Technical field

The present invention relates to comprise hoop structure (hoop structure) and also can deployed condition in use and deposit time folded state between carry out the field of the article folded, these article are circular structure at described folded state.The present invention is particularly applicable in the folding articles of tent or refuge's type.

Background technology

Traditionally, this kind of article comprise flexible sheets, such as, by one or more textile empiecement being fixed to hoop structure.

Term " hoop structure " is used in flexible sheets (being commonly called " the top cover fabric " of tent or refuge) when being fixed to flexible member (when article are in deployed condition, this flexible member forms open loop or closed-loop configuration) especially.Those flexible members can be made up of flexible rods (bar be especially made up of composite material, metal material or plastic material), and described bar can be connected to each other.

In some article, when article are in folded state when depositing, rods is in linear state, and only when article are set up, these rods are looping or dome-shaped structure.This is such as applied to some tents being commonly called yurt.

In other article, the element of hoop structure forms one or more closed loop, and those rings are particularly useful for making article present 3D shape.

Exemplarily, this article are described in document FR2877966, FR2805300 and FR2928953.

In those documents, when article are in folded state, the element of the hoop structure in closed loop constitutes the shape of multiple stacked ring.

In order to folding this article, reduce its overall dimension for the object of transporting and/or deposit, be necessary to perform a certain amount of operation, these operations have description in the above documents.

The ring that these operations are intended to by forming hoop structure generates subring, and makes these subrings stacked, so that the final structure forming flat disk shape.

Even so, but those operations are not very intuitively, are difficult to perform for unskilled user.Especially, they need the operation instruction with reference to introducing various step.Operation instruction can be lost or damage.In addition, for individual, always so uneasy with reference to this operation instruction while execution is folding.

Finally, especially for unskilled user, these operation execution are got up and are comparatively taken time.

Summary of the invention

Therefore, the object of the invention is to, except solving other problem, also solve and folding relevant the problems referred to above.

Therefore, the object of this invention is to provide a kind of folding articles of hoop structure, especially tent or refuge's type, wherein make it more easily become folded structure.

Therefore, in first scheme, the invention provides the folding articles of a kind of folding articles, particularly tent or refuge's type, it comprises and can be folded into circular and construct and the hoop structure comprising at least one ring.These article also have the flexible sheets and folding assist device that are fixed to hoop structure.

Folding assist device comprises at least one tractive element of the first source point of being connected to ring or the first source point along the flexible sheets of loop mapping.

When applying traction to it, tractive element is suitable for making the first source point be brought towards the first object point of ring or the first object point along the flexible sheets of ring, can form at least two subrings by torsion ring.

In addition, first object point and the first source point meet the following conditions (it is accumulation conditions, accumulative condition):

A) distance recorded along ring between the first source point and first object point is more than or equal to 2 π R _rupt, wherein R _ruptit is the limit curvature radius of ring;

B) when the shape of ring is the roughly on-plane surface with at least one main major axis and at least one main minor axis, { the first source point; First object point } to not both being positioned on main major axis, be not positioned on main minor axis yet; And

C) when the shape of ring is the oblong of the general plane with at least one main major axis, { the first source point; First object point } to not being positioned on main major axis.

Therefore, at least one step when at least one step when folding assist device makes puckered ring cuff structure and thus folded articles itself is easier, and described step comprises and forms at least two subrings by the ring of hoop structure.

Term " limit curvature radius R _rupt" ring can rupture when being used for representing that (such as when use composite fibre materials) exceeds this radius radius of curvature, or when (such as when using the materials such as such as steel) exceeds this radius, ring can be subject to permanent deformation and no longer return the radius of curvature of its original shape.

Therefore this limit curvature radius especially depends on the character of the material that ring uses, and depends on the diameter of the rods that can be made into ring.

Term " roughly oblong ring " is used for representing the ring of the shape with roughly elongated circle, and this elongated circle has at least one minor axis (or main minor axis) and at least one major axis (or main major axis).

This roughly oblong can be oval, it has single minor axis (or main minor axis) and single major axis (or main major axis) in this example.But, its overall shape that can present in an identical manner is the elongated circle with roughly line part, shown in some accompanying drawings (particularly Fig. 2 B and 2C) of this manual as described in detail below, in this example, this shape can have multiple major axis and/or multiple minor axis, at least one major axis namely except main major axis and/or at least one minor axis except main minor axis.

Detailed description of the invention

Fig. 1 is the schematic diagram of hoop structure in the embodiment of corresponding tent of article of the present invention.

This hoop structure generally includes basic ring 1, and this basic ring 1 can be plane or on-plane surface as shown in Figure 1, and nonplanar pressed on ring 2 is positioned on basic ring 1.

Each ring 1,2 can be made up of single hoop, so this hoop structure has two different hoops.Alternatively, the single hoop be shaped in a suitable manner can form basic ring 1 and pressed on ring 2.In another structure, hoop structure can comprise two different hoops, and each hoop 1,2 is made up of a part for one of them hoop and a part for another hoop.

It can be the shape of strict circle that these rings 1,2 present, but this shape is more typically roughly oblong, as shown in Fig. 1 reality.

Well imagine, the ring 1,2 in the present invention be rendered as have at least one minor axis a1, a2 and at least one major axis A 1, A2 elongated circular time be called as oblong.

Therefore, in the example of fig. 1, basic ring 1 has main major axis A 1 and main minor axis a1, and pressed on ring 2 has main major axis A 2 and main minor axis a2.

This roughly oblong shape can be ellipse as shown in Figure 2 A.Ring 1 be plane or nonplanar (in this example, shown in the view of Fig. 2 A is the ring 1 paved), so it has single minor axis (or main minor axis) a1, along main minor axis a1, there is relative summit s3 and s4, and single major axis A 1(or main major axis) A1, this main major axis A 1 has two relative summit s1 and s2.

As illustrated by figures 2 b and 2 c, overall shape can also be the thin oblong form with roughly line part, and in this example, ring 1 can have one or more minor axis a1, a1 ' and one or more major axis A 1, A1 '.

Therefore, in the example of Fig. 2 B, ring 1 can be plane or nonplanar (in this example, shown in the view of Fig. 2 B is ring 1 when paving), ring 1 has be parallel to main major axis A 1 two roughly straight sides, and this ring has single major axis A 1 or main major axis A 1(has two relative summit s1, s2 in this main major axis A 1), and multiple minor axis a1, a1 ' (at each minor axis a1, a1 ' all have two relative summit s3, s3 ' and s4, s4 ').

About these minor axises a1, a1 ', the minor axis a1 intersected vertically in mid point and the main major axis A 1 of relative summit s1 and s2 line is called as main minor axis a1.Another minor axis a1 ' is called as time minor axis a1 '.

In addition, in the example of Fig. 2 C, ring 1 be plane or nonplanar (in this example, shown in the view of Fig. 2 C is the ring 1 paved), ring 1 has be parallel to main minor axis a1 two roughly straight sides, and this ring has single minor axis a1 or main minor axis a1(has two relative summit s3 and s4 on this main minor axis a1), and multiple major axis A 1, A1 ' (there is two relative summit s1, s1 ' and s2, s2 on each major axis A 1, A1 ' ').

About these major axis A 1, A1 ', the major axis A 1 intersected vertically at mid point and the main minor axis a1 of relative summit s3 and s4 line is called as main major axis A 1.Another major axis A 1 ' is called as time major axis A1 '.

Should be clear that, the combination of Fig. 2 B and 2C has the ring of two roughly straight sides (described straight sides is parallel to any one in main minor axis a1 or secondary minor axis a1 ') and another two roughly straight sides (described straight sides is parallel to any one in main major axis A 1 or secondary major axis A1 ') by providing, therefore have multiple minor axis a1, a1 ' and multiple major axis A 1, A1 '.So this overall shape becomes approximate rectangular (may be square) with fillet.

Be called as roughly oblong annular and also cover roughly avette ring, as shown in Figure 2 D.

In figure 2d, ring 1 be plane or nonplanar (in this example, shown in the view of Fig. 2 D is the ring 1 paved), and it has minor axis a1(or main minor axis a1 that offset, that it has two relative summit s3 and s4 left), and there are two relative summit s1 and s2, the major axis A 1 that forms axis of symmetry.

More straight near the part of summit s1, and part between s3 and s2 on side and the part between s4 and the s2 on opposite side more straight, then this avette more trending towards becomes the triangle with fillet.

In the unshowned structure of Fig. 2 D, wherein ring 1 has two parallel roughly line parts, so except main major axis A 1 and/or main minor axis a1, is the secondary axes of major axis or minor axis respectively by having one or more.

The feature of folding articles of the present invention (describing its example by concrete with reference to Fig. 6 to Fig. 9 below) is, they have for assisting the device folded, and this device forms at least two subrings for assisting by least one ring of the hoop structure of article.

By using folding assist device to obtain formation subring, thus take source point to impact point, each in above-mentioned point is arranged to one of them ring along structure with being directly or indirectly.

However, but source point and impact point must form a pair point meeting a certain amount of accumulation conditions, are described this referring to Fig. 3 A and 3B.

Therefore, Fig. 3 A is the view of the ring 1 that the circular that can be plane or on-plane surface (in this example, the corresponding ring 1 paved of the view of Fig. 3 A) is shown.

In order to discussed { source point is described; Impact point } to one of them condition that must meet, ring 1 illustrates arbitrary source point P _sand a series of impact point P _cwith a P ₂, be a little all arranged to record along ring 1 distance be more than or equal to 2 π R _rupt, wherein R _ruptit is the limit curvature radius of ring.This distance is represented by the ring 1 of dotted lines.

These P _cand P ₂all form source point P _ssuitable impact point.

But, by the meaning of the present invention, the some P in Fig. 3 A ₁source point P can not be formed _simpact point because its distance recorded along ring 1 on ring 1 is less than 2 π R _rupt.

Well imagine, by the meaning of the present invention, limit curvature radius is that this ring can rupture or this ring can be subject to permanent deformation and can not return the radius of curvature of its original shape when exceeding this radius of curvature, therefore this limit curvature radius depends on the material (such as glass fiber, wirerope or line) that ring uses especially, but also depends on the diameter of the rods forming ring.

In addition, although shown in Fig. 3 A is nonplanar roughly annulus 1 paved, but the main major axis A 1 of nonplanar roughly annulus 1 is defined as the axle through two extreme values (plane of the center tangent of these two extremal distances and ring 1 farthest), and main minor axis a1 is defined as perpendicular to A1 and is arranged in the axle with the plane of the center tangent of ring 1.

In this case, by the meaning of the present invention, put { P ₁; P ₂as putting { P ₂; P ₁equally { source point can not be formed; Impact point } right, because they are positioned in major axis A 1.

Similarly, for two the some P be positioned on minor axis a1 _c, when they are arranged on described minor axis a1 really, these press the meaning of the present invention can not form { source point; Impact point } right.

In addition, Fig. 3 B illustrates that the concrete situation of oblong ring 1(is oval) figure, thus therefore it have single major axis A 1(or main major axis A 1) and single minor axis a1(or main minor axis a1), this ring can be plane, or it can be nonplanar (in this example, the corresponding ring 1 paved of the view of Fig. 3 B).

In this case, { source point is corresponded to; Impact point } { P to (its by of the present invention be meant to suitable) _s; P _cto meeting the above-mentioned condition identical about the distance recorded along ring 1 between them described with reference to Fig. 3 A.

Therefore, from the source point P locating (upper left 1/4th at ring 1) along ring 1 _sstart, all some P _call suitable impact point, as long as the distance that they record along ring 1 on ring 1 is more than or equal to 2 π R _rupt.Again, this distance is represented by the ring 1 of dotted lines.

On the contrary, still from the source point P being positioned at (upper left 1/4th at ring 1) on ring 1 _sstart, only will put P ₁the distance that ring 1 records along ring 1 is less than 2 π R _rupt, it does not form suitable impact point.

However, except the condition about the distance recorded along ring between source point and impact point, and only for the ring 1 of the general plane such as limited above or oblong shape, simultaneously as Fig. 3 B exemplarily shown in, { source point; Impact point } to also meeting additional conditions.

Source point and impact point must not be positioned in the main major axis A 1 of ring 1.

Therefore, in the example of Fig. 3 B, be positioned at the some P in main major axis A 1 _cthus suitable { the source point by the meaning of the present invention can not be formed with the relative point (without Reference numeral) in main major axis A 1; Impact point } right.

In addition, be under the special case of the non-planar rings 1 of paving at the oblong ring 1 shown in Fig. 3 B, { source point; Impact point } point that formed two that both must not correspond to main minor axis a1 relative summits is right, also do not correspond to the point that the relative summit of two of main major axis A 1 formed right.

Therefore, for nonplanar oblong ring 1, shown in Fig. 3 B, by the some P on summit being positioned at main minor axis a1 ₄with the some P at the summit on the other side place be positioned on main minor axis a1 ₃the point formed is to the suitable { source point that can not form by the meaning of the present invention; Impact point } right.

In addition, and still when nonplanar oblong ring 1, the some P in main major axis A 1 is positioned at _ccan not form by the suitable { source point of the meaning of the present invention with the corresponding point (without Reference numeral) be positioned in main major axis A 1; Impact point } right.

But, as shown in Figure 2 B, for the plane of multiple the minor axis a1 ' had except main minor axis a1 and/or multiple major axis A1 ' or nonplanar oblong ring 1, if the secondary minor axis a1 ' considered is obviously different from main minor axis a1, or the secondary major axis A1 ' considered is obviously different from main major axis A 1, so correspond to { the source point on the relative summit of one of one of time minor axis a1 ' or secondary major axis two; Impact point } to the suitable { source point that can form by the meaning of the present invention; Impact point } right.

Except the condition about the minimum range between source point and impact point, (special case is about non-planar rings to there are those two exceptions above-mentioned, another special case is about the oblong ring of plane) one of reason relevant with the impossibility of the difficulty of expectation distortion or reality that obtain ring, even when the above-mentioned condition about the minimum range between these two points meets.

Need it is clear that, circular or oblong non-planar curve is usually used to the curve that expression represents at least one linear axis (major axis of oblong curve or minor axis) herein, the plane of described linear axis and at least two extreme values (these two extreme values correspond to the plane point farthest of the center tangent of distance on curve and curve, but are never limited to this curve) is comprised with the center tangent of curve.

Therefore, by this oblong curve, Fig. 1 shows such non-planar curve.

For the oblong curve 1 of corresponding basic ring 1, minor axis a1 is straight line, and prepares to rest formation with on the ground of the plane of the center tangent of curve, and major axis A 1 is curve, and passes via two extreme values corresponding to distance ground two points farthest.

For the oblong curve 2 of corresponding pressed on ring 2, minor axis a2 is straight line, and preparation formation has the top with the tent of the plane of the center tangent of curve, principal axis A 2 is curves, and passes via two extreme values corresponding to distance tangential plane two points farthest.

Fig. 4 and Fig. 5 is two examples that the method that assistance of the present invention folds is shown.

As described above with reference to Figure 1, and example as the article shown in referring to Fig. 6 to Fig. 9 is described in more detail, hoop structure generally includes multiple ring.In this case, method of the present invention is applied to separately each ring, or is applied to the virtual ring formed by other ring stacked.

Before the method performing formation two subrings, or while manner of execution, carry out stacked ring by initial step.

Finally, before folding or in folding period, when this structure in fact comprise multiple overlie one another or stacked ring time, two virtual subrings are considered to be formed from single virtual ring.But, should be clear that, so the same way that each virtual subring corresponds to stacked multiple rings by single initial virtual ring corresponds to stacked multiple subrings.

For simplicity, the method is illustrated by the schematic diagram only with a ring, no matter this ring is single ring or stacked ring.

Therefore, in the example depicted in fig. 4, hoop structure comprises nonplanar oblong ring 1, this ring 1 have be marked thereon, meet the above source point 5a that imposes a condition and impact point 6.

One end 5a of tractive element 5 is fastened to source point 5a.Tractive element 5 in the form of elongated flexible member 5, such as, is rope 5.It can be band or simple flexible grip equally.

By this tractive element of tractive, the source point 5a of ring 1 can be taken to the impact point 6 of same ring 1 by user.

In order to promote this operation, mark 6 can be set at impact point 6 place, to provide the accurate instruction which some source point 5a need to be brought towards for user.

Can also provide be positioned at impact point 6 induction element formula attachment device 6(for simplicity, be still Reference numeral 6 in the diagram), tractive element 5 with permanent or interim mode through itself and insert, this element is such as the guiding ring type of rigidity or flexibility.

From the view of Fig. 4 (a), this tractive element 5 of user's tractive, preferably simultaneously by pin or hand retaining ring 1.

As shown in the view of Fig. 4 (b), the result of this operation starts to make source point 5a turn to impact point 6.Represented by the curved arrow in this view, so the part 100,101 that ring 1 starts between source point 5a on ring 1 and impact point 6 is reversed.

By continuing this tractive element 5 of tractive, source point 5a continues to turn to impact point 6, and continues to reverse, to arrive the structure shown in view of Fig. 4 (c), result forms two subring 1a and 1b.

Particularly, the part 100,101 that the formation being shown as ring 1 is in the subring 1a of rollover states is reversed.The remainder of ring 1 forms subring 1b.

As long as source point 5a and impact point 6 start diametrically, as shown in the view of Fig. 4 (a), then obtained two subrings 1a, 1b are roughly symmetrical, and they have identical girth, as shown in the view of Fig. 4 (c).

In the example depicted in fig. 5, hoop structure comprises nonplanar oblong ring 1 equally, and it has an impact point 6 and two source point 5a, 5b marked, { source point 5a thereon; Impact point 6} to { source point 5b; Each of impact point 6} centering all meets above-mentioned condition.

One end 5a of tractive element 5 is fastened to source point 5a, and other end 5b is fastened to source point 5b.

Again, the form of this tractive element 5 in elongated flexible member 5 is such as rope 5.It can be band or simple flexible grip equally.

By carrying out this tractive element 5 of tractive via ring 12, the source point 5a of ring 1 can be taken to the impact point 6 of same ring 1 by user, can take the source point 5b of ring 1 to same impact point 6 simultaneously.

Again, in order to make operation easier, mark 6 can be arranged to be positioned at impact point 6 place, source point 5a, 5b are with the accurate instruction of putting to which for user provides.

Can also provide the object of induction element formula attachment device 6(in order to simplify being positioned at impact point 6, be still Reference numeral 6 in Figure 5), tractive element 5 forever or provisionally inserts through it, and this element is such as guide ring type.

Should see, can have two different tractive elements equally, one end of each tractive element is fastened to one in source point 5a, 5b respectively, the opposite end of two tractive elements freely, for user's tractive.

From the view of Fig. 5 (a), user via this tractive element 5 of ring 12 tractive, preferably simultaneously by pin or hand retaining ring 1.

The result of this operation makes source point 5a, 5b initial turn point 6, as shown in the view of Fig. 5 (b).As shown in the curved arrow in this view, so the part 100,101 and 102 of the ring 1 of ring 1 beginning first between source point 5a and impact point 6, secondly between source point 5b and impact point 6 is reversed.

By this tractive element 5 of continuous tractive, source point 5a, 5b continue to turn to impact point 6, and twist, to reach the structure shown in view of Fig. 5 (c), form subring 1a, 1b and 1c.

Particularly, reverse the part 100,101 being in rollover states being first shown as ring, next is shown as the part 100,102 being in rollover states of ring 1.Sub-fraction and the part 101 of part 100 form subring 1a.Residue sub-fraction and the part 102 of part 100 form subring 1b.The remainder of ring 1 forms subring 1c.

In this example, two source point 5a and 5b are roughly arranged on the summit of the main shaft of nonplanar oblong ring 1, corresponding to two peaks.In addition, impact point 6 is roughly positioned at one of summit of the minor axis of nonplanar oblong ring 1, corresponding to one of two minimum points.

Therefore, three subrings 1a, 1b and 1c are obtained.Postulated point 5a, 5b are initially positioned on ring 1 as in the view of Fig. 5 (a), then the girth of subring 1c is the only about half of girth of ring 1, and the respective girth of two subrings 1a, 1b is roughly the same, is about 1/4th of the girth of ring 1.Therefore the girth of ring 1c is about the twice of the girth of ring 1a or 1b.

As shown in Figure 6, source point 5a, 5b by the mode selected be preferably, three subrings 1a, 1b and 1c all have roughly the same girth (that is, ring 1 girth 1/3rd), and relative to each other roughly symmetrical.For this reason, these source points 5a, 5b can lay respectively at 1/3rd distances between one of summit of the main minor axis of one of summit of the main major axis of ring 1 and ring 1, and impact point 6 is positioned at the relative summit place of the main minor axis of ring 1.

Therefore, in the example depicted in fig. 6, hoop structure comprises nonplanar oblong ring 1 equally, and this ring 1 has two source points 5a, 5b and an impact point 6 of marking thereon, { source point 5a; Impact point 6} to { source point 5b; Impact point 6} is to all meeting above-mentioned condition.

Again, tractive element 5 in the form of elongated flexible member 5, such as, is rope 5.It can be band or simple flexible grip equally.

By via this tractive element 5 of ring 12 tractive, the source point 5a of ring 1 can be taken to the impact point 6 of same ring 1 by user, and takes the source point 5b of ring 1 to same impact point 6 simultaneously.

Again, in order to promote operation, mark 6 can be set at impact point 6 place, so as user provide source point 5a, 5b be brought towards which put accurate instruction.

The object of induction element formula attachment device 6(in order to simplify being arranged on impact point 6 place can also be provided, be still Reference numeral 6 in figure 6), tractive element 5 inserts in permanent or interim mode through this induction element formula attachment device 6, and this induction element can be such as guide ring type.

Should observe, can have two different tractive elements in an identical manner, one end of each tractive element is fastened to one of source point 5a and 5b respectively, and user is at its relative free end tractive.

From the view of Fig. 6 (a), user via its this tractive element 5 of ring 12 tractive, preferably simultaneously by hand or pin retaining ring 1.

The initial results of this operation makes source point 5a, 5b turn to impact point 6, as shown in the view of Fig. 6 (b).As shown in the curved arrow in this view, the part 100,101 and 102 of the ring 1 subsequently first between source point 5a and impact point 6, secondly between source point 5b and impact point 6 starts to reverse.

By continuing this tractive element 5 of tractive, source point 5a, 5b continue to turn to impact point 6, and continue to reverse, thus reach the structure shown in view of Fig. 6 (c), form three subrings 1a, 1b and 1c.

More accurately, reverse the part 100,101 being first shown as the ring 1 being in rollover states, next is shown as the part 100,102 of the ring 1 being in rollover states.The sub-fraction of part 101 and part 100 forms subring 1a.Another fraction of part 102 and part 100 forms subring 1b.The remainder of ring 1 forms subring 1c.

In this example, two source points 5a, 5b roughly one of summit of major axis and present nonplanar oblong ring 1 minor axis one of summit between 1/3rd distances.In addition, impact point 6 is roughly positioned at one of summit of the minor axis of nonplanar oblong ring 1, corresponding to one of two minimum points.

Therefore, obtain subring 1a, 1b and 1c that three girths are roughly the same, 1/3rd of the girth of the corresponding ring 1 of this girth.

Fig. 7 illustrates another example of method for folding of the present invention, and the structure that structure is similar by describing to above example starts and reference Fig. 6, more specifically as shown in the view of Fig. 6 (a).

Therefore, the hoop structure shown in Fig. 7 comprises nonplanar oblong ring 1, and this ring 1 has two source points 5a, 5b and impact point 6 of marking thereon, { source point 5a; Impact point 6} to { source point 5b; Impact point 6} is to all meeting above-mentioned condition.

Again, one end 5a of tractive element 5 is fastened to source point 5a, and other end 5b is fastened to source point 5b.

Therefore this tractive element 5 is the form of elongated flexible member 5 again, such as rope 5, and can be made up of band or simple flexible grip, or comprises band or simple flexible grip.

By this tractive element 5 of tractive, by its ring 12, user takes the source point 5a of ring 1 impact point 6 of same ring 1 to, also takes the source point 5b of ring 1 to same impact point 6 simultaneously.

As in the examples described above, in order to promote operation, mark 6 can be set at impact point 6 place, to be brought towards for user provides source point 5a, 5b the accurate instruction which puts.

The object of induction element formula attachment device 6(in order to simplify being positioned at impact point 6 place can also be provided, be still Reference numeral 6 in the figure 7), tractive element 5 inserts in permanent or interim mode through this guiding piece formula attachment device 6, and induction element such as guides ring type.

Can also provide the tractive element that two different, one end of each tractive element is fastened to source point one of 5a, 5b respectively, and user is at its relative free end tractive.

From the view of Fig. 7 (a), user is via this tractive element 5 of ring 12 tractive.

The result of this operation makes source point 5a, 5b initial turn point 6, as Fig. 7 (b) and 7(c) view shown in.

But although from identical structure, in this example, the torsion of subring is not occur by the mode identical with the example shown in above-mentioned Fig. 6 with formation.

In this example, between 5a, 5b and the part of the ring 1 relative with point 6 (that is, the part of the last formation subring 1c as shown in the view of Fig. 7 (d)) pass under the part 100 corresponding to the ring 1 near point 6.This specifically illustrates in the view of Fig. 7 (c).

When some 5a, 5b complete more near point 6 respectively, ring 1 between a 5a with some 5b and this part relative with point 6 reverses, thus formation subring 1c.

Although some 5a, 5b and 6 should be roughly stacked at the end of these operations, in the view of Fig. 7 (d), they are shown as separation, to demonstrate the result of torsion, how corresponding point 6 overturns in the position of some 5a, 5b.

Finally, the sub-fraction of part 101 and part 100 forms subring 1a, and another part of part 102 and part 100 forms subring 1b, and the remainder of ring 1 forms subring 1c.

As in the above examples, two source points 5a, 5b are disposed generally on 1/3rd distances between one of summit of one of summit of the major axis of nonplanar oblong ring 1 and minor axis.In addition, impact point 6 is disposed generally on one of the summit of the minor axis of nonplanar oblong ring 1 place, one of corresponding two minimum points.

Therefore, three subrings 1a, 1b and 1c that the girth girth of the corresponding ring 1 (1/3rd) is roughly the same are obtained equally.

Should observe, the example of three shown in Fig. 5 to 7 provides single target point 6, two source point 5a and 5b, but can arrange two different impact points in the same way.So result will be three subrings equally, but they are by asymmetric and girth different.

Fig. 8 to 12 is the figure of four examples of article of the present invention (especially tent-type) respectively.

In the example of fig. 8, tent has the hoop structure be similar to reference to described in Fig. 1, and just basic ring 1 is plane.

Therefore, tent comprise flexible sheets 3,4(its be such as made up of the multiple textile empiecements 3,4 being fixed to the hoop structure comprising basic ring 1 and pressed on ring 2).

Tractive element 5 is positioned at tent, and presents the form point 5a of basic ring 1 being connected to the first band of the point 21 of pressed on ring 2, and this tractive element extends with endless belt.

Tractive element 5 or be directly fixed to ring 1 at a 5a place, or be directly fixed to flexible sheets 3,4 at a 5a place.If it is fixed to sheet, then tractive element 5 in fact such as can be connected to flexible shroud by suture, and this flexible shroud forms the part of flexible sheets 3,4 and inserts wherein for basic ring 1.

Point 6 is diametrically relative with a 5a on basic ring 1.So user can perform method of the present invention as specifically described with reference to Fig. 4.

Point 6 can be arranged to and enclose 6 and coordinate, user by the free end of tractive element 5 through circle 6, this tractive element 5 of tractive simultaneously.

By continuing this tractive element 5 of tractive, the point 5a of basic ring 1 and both points 21 of pressed on ring 2 with the point 6 to basic ring 1, thus are positioned on the point 21 of pressed on ring 2 because tractive force is applied to by user, form two subrings, a subring comes from basic ring 1, and another subring comes from pressed on ring 2.

In this embodiment, by continuing a vertical pulling, especially due to the rebound effect of the rope of the hoop structure 1,2 of bending installation and by means of the prestressing force in flexible sheets 3,4, the subring formed before two trends towards auto-steering each other.

In the method for folding of this tent, this structure makes it can surmount the basic steps being formed two subrings by a ring, and until stacked two subrings (this is final purpose), especially reduces overall dimension.

Still in this configuration, once two subrings are stacked, so user can use the band 5 of the part forming tractive element 5 around the square position formed by two stacked subrings, then makes band 5 guide through another of point 7 place being now positioned at basic ring 1 and encloses.

For putting 6,7, special mark can be set, so that user more easily performs the method by using the mark of such as color and/or digital form.

Then by tractive band 5, user performs method of the present invention as shown in Figure 4 again.

Last two subrings of such formation manually can be overlapped each other by user, are then again kept together by band 5.

/ 4th of a girth of the ring 1,2 of hoop structure is substantially equal to like this by the girth of the square position of stacked described subring acquisition.

Therefore, put 5a and point 6 form by the meaning of the present invention, { the source point that meets above-mentioned condition; Impact point } right.Similarly, once two the first subrings are formed and stacked, point 6 and point 7 form equally by the meaning of the present invention, { the source point that meets above-mentioned condition; Impact point } right.

In the example of figure 9, the tent with the hoop structure identical with Fig. 8 can be seen.

Therefore, tent comprise equally flexible sheets 3,4(its be such as made up of the multiple textile empiecements 3,4 being fixed to the hoop structure comprising basic ring 1 and pressed on ring 2).

In this example, tractive element 5 is arranged in tent again, but it is the form of such band, first this band is connected to some 5a on basic ring 1 and the point 17 in pressed on ring 2, is then connected to the point 18 diametrically relative with point 17 in pressed on ring 2, is finally connected to the point 6 diametrically relative with a 5a on basic ring 1.

Again, tractive element 5 or be directly fixed to ring 1 at a 5a place, or be directly fixed to flexible sheets 3,4 at a 5a place.When being fixed to sheet, tractive element 5 in fact such as can be connected to flexible shroud by suture, and this flexible shroud forms a part for flexible sheets 3,4 and inserts wherein for basic ring 1.

In other words, as before with in this example of following example, the point discussed physically can be positioned in an identical manner on discussed ring 1,2 or may to have along the flexible sheets 3 of the ring 1,2 discussed, this sheet of 4(the sheath that ring 1,2 passes) on.

User can perform method of the present invention as concrete with reference to Fig. 4 explanation.

By (such as via being positioned at the circle 12 of free end of tractive element 5 or the ring 12 that formed via the free end of tractive element 5) this tractive element 5 of tractive, the point 5a of basic ring 1 is with the point 6 to basic ring 1 by user, simultaneously by the point 17 of pressed on ring 2 with the point 18 to pressed on ring 2, form two subrings by both basic ring 1 and pressed on ring 2 thus.

In this embodiment, especially due to the rebound effect of the rope of the hoop structure 1,2 of bending installation and by the prestressing force in flexible sheets 3,4, the subring formed before two trends towards auto-steering each other.

As in the example of fig. 8, therefore this structure makes it can surmount the basic steps being formed two subrings by a ring, and until stacked two subrings (this is final purpose), especially reduces overall dimension.

Still in this configuration, once two subrings are stacked, so user can make band 5 again be passed in the guiding circle of the point 8 place successive position fixes of the point 7 of basic ring 1, the point 19 of pressed on ring 2, the point 20 of pressed on ring 2 and basic ring 1.

Last two subrings of such formation manually can be overlapped each other by user, are then held togather by band 5.

Again, 1/4th of the girth of the ring 1,2 of hoop structure is substantially equal to by the girth of the square position of stacked described subring acquisition like this.

Therefore, put to 5a & 6} and every in 17 & 18} all form for a pair by the meaning of the present invention, { the source point that meets above-mentioned condition; Impact point } right.Similarly, once two the first subrings are formed and stacked, then put to 7 & 8} and 19 & 12} form equally by the meaning of the present invention, { the source point that meets above-mentioned condition; Impact point } right.

The example of Figure 10 forms the 3rd example with the tent-type article of the hoop structure identical with Fig. 8 with Fig. 9.

Therefore, tent comprises flexible sheets 3,4 equally, and it is such as made up of textile empiecement 3,4 and is fixed to the hoop structure comprising basic ring 1 and pressed on ring 2.

In this example, tractive element 5 is the simple ropes be positioned at now outside tent.Rope 5 is connected to the some 5a of pressed on ring 2.

Other important point is shown in Figure 10, and they preferably mark by such as special color and/or numeral, so that user more easily performs the method.

Therefore, the approximate below that point 13 is positioned at a 5a on basic ring, point 6 is positioned to put 13 diametrically relative on basic ring 1.

Point 14 be positioned in pressed on ring 12 a little 6 approximate above, point 15 be positioned in pressed on ring 2 equally and a 5a relative to the major axis symmetry of pressed on ring 2.

Point 7 is positioned at the approximate below of a little 15 on basic ring 1, and point 8 is arranged on basic ring 1, diametrically relative with point 7.

Point 16 be positioned in pressed on ring 2 a little 8 approximate above, point 9 is positioned in pressed on ring 2 equally, overlaps or closely put 5a with a 5a.

Again, such as, by being connected to the flexible shroud inserting flexible sheets 3,4 wherein for the ring discussed, tractive element 5 or be directly fixed to basic ring 1 or pressed on ring 2 at each place's point, or be directly connected to flexible sheets 3,4 at those places.

All these points are all provided with and guide circle or similar item, more easily to perform the method.

User is therefore, it is possible to perform method of the present invention as with reference to Fig. 4 specific explanations.

Therefore, user is by making rope 5 from the guiding circle at outside crossing point 13,6 and 14 place of tent, then applying tractive force comes to rope 5.

By rope for traction 5, the some 5a of pressed on ring 2 is with to the point 14 of pressed on ring 2 by user, simultaneously by the point 13 of basic ring 1 with the point 6 to basic ring 1.

Especially due to the rebound effect of the rope of the hoop structure 1,2 of bending installation and by means of the prestressing force in flexible sheets 3,4, the subring formed before two trends towards auto-steering each other.

Therefore, as Fig. 8 and Fig. 9 example shown in, this structure makes it surmount to comprise the basic steps being formed two subrings by a ring, and until stacked two subrings (this is final purpose), especially reduces overall dimension.

Once two subrings are stacked, so user can make band 5 again be passed in the guiding circle of the point 9 place successive position fixes of the point 15 of pressed on ring 2, the point 7 of basic ring 1, the point 8 of basic ring 1, the point 16 of pressed on ring 2 and last pressed on ring.

Then, by enough rope for traction 5 at full tilt, user performs method of the present invention again as shown in Figure 4.

Last two subrings of such formation manually can be overlapped each other by user, then keep together by rope 5.

Therefore, put and 5a & 14 and 13 & 6 formed by the meaning of the present invention separately and meets { the source point of above-mentioned condition; Impact point } right.Similarly, once two the first subrings are formed and stacked, then o'clock 15 & 16 and 7 & 8 are formed equally by the meaning of the present invention and meets { the source point of above-mentioned condition; Impact point } right.

Figure 11 is the another example of tent-type folding articles of the present invention, but it uses the method for folding of the type described with reference to Fig. 6 or Fig. 7.

This tent comprises flexible sheets 3,4 equally, and it is made up of multiple textile empiecements 3,4 of the hoop structure being fixed to the basic ring 1 and nonplanar pressed on ring 2 comprising general plane.

Tractive element 5 is similar to the tractive element briefly described with reference to Fig. 6 and Fig. 7.It comprises the rope 5 that first end is connected to the some 5a of pressed on ring 2, the second end is connected to the some 5b of pressed on ring 2.

Point 5a, 5b 1/3rd distances roughly between one of summit of one of summit of the major axis of nonplanar oblong pressed on ring 2 and minor axis.

From a 5a, rope 5 is through the guiding circle 11 at point 23 place be positioned on basic ring 1.From a 5b, rope 5 is through the guiding circle 11 at point 22 place be positioned on basic ring 1.

/ 3rd distances of point 22,23 all roughly between one of summit of one of summit of the major axis of the oblong basic ring 1 of plane and minor axis.

Respectively from point 22 and 23, rope 5 to be positioned at basic ring 1 main minor axis one of summit place basic ring 1 on point 6 advance.

At this point 6 place, rope 5 also through guiding circle 11 or similar item, and forms the ring 12 that user is easier to grasping.

Again, tractive element 5 or be directly fixed to basis 1 or pressed on ring 2 at each some place, or be directly fixed to flexible sheets 3,4 at those some places, be such as connected to the flexible shroud making discussed ring insert flexible sheets 3,4 wherein.

User therefore, it is possible to perform method of the present invention as explained in concrete reference Fig. 6 or Fig. 7.

Therefore, by applying tractive force via ring 12 pairs of ropes 5, some 5a is initially brought towards a little 23, puts 5b and is initially brought towards a little 22.

By continuing to apply tractive force to rope 5, realize reversing, and formed like that as is seen in fig. 6 or fig. 7 three subrings.

In this configuration, once some 5a is brought to a little 23, these two points are considered and corresponding to making, pressed on ring 2 and the stacked virtual ring of basic ring 1 are overlapping.Similarly, once some 5b is brought to a little 22, these two points are considered and make pressed on ring 2 and the stacked virtual ring of basic ring 1 overlap in correspondence.

Therefore, put (5a(or 23); 6) and (5b(or 22); 6) to form respectively by the meaning of the present invention and to meet (source point, the impact point) of above-mentioned condition right.

Therefore obtain square position by stacked subring, the girth of this disk is substantially equal to 1/3rd of the girth of the ring 1,2 of hoop structure.

Figure 12 is the figure of the another example of tent-type folding articles of the present invention.

Tractive element 5 is identical with tractive element described above.Exemplarily, it comprises rope 5.The first end of this rope 5 is connected to the point 23 of basic ring 1, then before the rearmost point 6 through pressed on ring 2, via point 5a and 5b of pressed on ring 2 and another point via basic ring 1 22 to pass.

/ 3rd distances of point 22,23 roughly between one of summit of one of summit of the major axis of the oblong basic ring 1 of plane and minor axis.

Point 6 is positioned at one of the summit of the main minor axis of basic ring 1 place.

Rope 5 can via the guiding circle system similar to the guiding circle system 11 that the example of above reference Figure 11 describes through various each point listed above.

At point 6 place, rope 5 can form the similar ring of the ring 12 that describes as Figure 11 to above reference example, so that user more easily catches.

Again, tractive element 5 or be directly fixed to basic ring 1 or pressed on ring 2 at each some place, or be directly fixed to flexible sheets 3,4 at those some places, be such as connected to the flexible shroud making discussed ring insert flexible sheets 3,4 wherein.

So user can perform method for folding of the present invention as explained below.

Therefore, by applying tractive force to rope 5, point 23 is brought towards a 5a, is almost brought towards a little 22 with time point 5b simultaneously.

By continuing to apply tractive force to rope 5, the some 5b and 22 be brought towards each other is brought towards a little 6.

Finally, the some 5a and 23 be brought towards each other is brought towards a 5b, 22 and 6.

Such generation is reversed and three subrings needed for being formed.

As explained with reference to above example, once some 5a has been brought to a little on 23, these two points have been considered and have overlapped on the virtual ring of the stacked pressed on ring 2 of correspondence and basic ring 1.Similarly, once some 5b has been brought to a little on 22, these two points have been considered and have overlapped on the virtual ring of the stacked pressed on ring 2 of correspondence and basic ring 1.

Therefore, put to 5a(or 23); 6} and 5b(or 22); 6} is formed { source point, the impact point } that meet above-mentioned condition by the meaning of the present invention respectively.

Produce square position by being stacked in folding period by reversing the subring that formed like this, the girth of this square position is substantially equal to 1/3rd of the girth of the ring 1,2 of ring structure.

In any embodiment, can be arranged to use retention device, the structure that this retention device is applicable to making to fold remains on intermediateness and applies any power to obtain this maintenance without the need to user.
