Description

Folding articles with hoop structure

Technical field

The present invention relates to comprise hoop structure (hoop structure) and deployed condition that can be in use and the folded state when depositing between the field of the article that fold, these article are circular structure at described folded state.The present invention specifically is applied in the folding articles of tent or refuge's type.

Background technology

Traditionally, these class article comprise flexible sheets, for example by one or more textile empiecements that are fixed to hoop structure.

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

In some article, when article were in folded state when depositing, rods was in linear state, and only when article were set up, these rods are loopings or dome-shaped structure.This for example is applied to be commonly called some tents of yurt.

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

As example, this article have been described in document FR2877966, FR2805300 and FR2928953.

In those documents, when article were in folded state, the element that is the hoop structure of closed loop had consisted of the shape of a plurality of stacked rings.

For folding this article, reduce its overall dimension for the purpose of transporting and/or depositing, be necessary to carry out a certain amount of operation, these operate in above-mentioned document description.

These operations are intended to generate subring by the ring that consists of hoop structure, and make these subrings stacked, in order to finally form the structure of square position shape.

Even so, but those operations are not very directly perceived, are difficult to carry out for unskilled user.Especially, they need with reference to the operation instruction of introducing various steps.Operation instruction can be lost or damage.In addition, for the individual, always so uneasy with reference to this operation instruction when execution is folding.

At last, especially for unskilled user, these operations are carried out to get up to take time.

Summary of the invention

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

Therefore, the purpose 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 the 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 the hoop structure that at least one ring was constructed and comprised to circular.These article also have flexible sheets and the folding assist device of the hoop structure of being fixed to.

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

When it being applied traction, the tractive element is suitable for making the first source point by the first object point with the flexible sheets of encircling to first object point or the edge of ring, in order to can form at least two subrings by torsion ring.

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

A) distance that the edge ring records between the first source point and first object point is more than or equal to 2 π R _Rupt, R wherein _RuptIt is the limit curvature radius of ring;

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

C) when the ring be shaped as the oblong of the general plane with at least one main major axis the time, { the first source point; The first object point } to not being positioned on main major axis.

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

Term " limit curvature radius R _Rupt" be used for expression (for example in the situation that use composite fibre materials) radius of curvature that when exceeding this radius, ring can rupture, perhaps (such as when use during such as materials such as steel) when exceeding this radius ring can be subject to permanent deformation and no longer return to the radius of curvature of its original shape.

Therefore this limit curvature radius especially depends on the material character 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 to have the ring of the shape of 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.Yet, its overall shape that can present in an identical manner is to have the roughly elongated circle of line part, as described in detail below shown in some accompanying drawings of this manual (particularly Fig. 2 B and 2C), in this example, this shape can have a plurality of major axis and/or a plurality of minor axis, i.e. time major axis of at least one except main major axis and/or at least one time minor axis except main minor axis.

In all cases, main shaft (no matter being major axis or minor axis) is all axis of symmetry, and secondary axes (no matter major axis or minor axis) are not axis of symmetry, and all minor axises (no matter main shaft or secondary axes) are all perpendicular to all major axis (no matter main shaft or secondary axes).

As described below shown in some accompanying drawings of this manual (especially Fig. 2 D), by the present invention's meaning this roughly oblong can be also to have or line part roughly avette roughly not.In this case, this shape also has one or more major axis and one or more minor axis, namely has main major axis and one or more times possible major axis, and has main minor axis and one or more times possible minor axises.

In the first variant embodiment, pulling device is fixed to flexible sheets by direct stitching or via textile section (for example for ring insertion sheath wherein) in the middle of being sewn onto.

In the second modification (it can make up with the modification of front), folding assist device comprises the mark that is arranged on first object point place.

In the 3rd variant embodiment (its can with one or two combination of aforementioned variant), the tractive element is fixed to the second source point of ring or along second source point of flexible sheets of ring, and the tractive element is suitable for making the second source point can be by band to the second impact point of ring or along the second impact point of the flexible sheets of described ring by this tractive element being applied tractive force.

First object point and the second impact point can overlap.

In another modification (its can with the combination of one or more aforementioned variant), pulling device be the elongated flexible element of rope, band or flexible grip formula for example, and its first end is fastened to the first source point.

The first end of elongated flexible element can be fastened to the first source point in described article subsequently.

In addition, folding assist device can comprise the first induction element of stereosphere or textile ring type, and it is fit to make the second end of elongated flexible element therefrom to pass and is positioned at the first object point.

As the alternative of aforementioned variant, and with the 3rd modification combination, pulling device is the elongated flexible element of rope, band or flexible grip formula for example, its first end is fastened to the first source point, the second end is fastened to the second source point.

So elongated member can form one or more rings between its first end and the second end, folding assist device comprises the first induction element and second induction element of stereosphere for example or textile ring type, and it is fit to make ring therefrom to pass and lay respectively at first object point and the second impact point.

In another modification (it can make up with one or more aforementioned variant), ring is basic ring, and flexible sheets comprises opening.So the first source point is arranged to relative with opening in article, and be positioned on described basic ring.

Alternatively, ring is pressed on ring, and it is outer and be positioned at described pressed on ring place that the first source point is positioned at article.

In another modification (its can with the combination of one or more aforementioned variant), tractive element, ring and flexible sheets make the tractive element with permanent or interim mode and ring or with fix at the series of points place along the flexible sheets of described ring.

These points one after the other consist of the impact point of the point of the continuous source point of point of the back separately in series of points and the front separately in series of points.

So the tractive element be suitable for source point by can make a series of point to tractive element tractive one or many by area one after the other or simultaneously to its impact point, so that by means of one after the other reversing described ring (1,2) can form a plurality of subrings, described subring may be the form of stacked circle.

When the description of reading following preferred embodiment, it is clearer, more complete that other features and advantages of the invention will seem, these embodiment provide as non-limiting example and with reference to accompanying drawing, in accompanying drawing:

Fig. 1 is the figure of example that the hoop structure of article of the present invention is shown;

Fig. 2 A to 2D is the figure of example of ring that the hoop structure of article of the present invention is shown;

Fig. 3 A and 3B are the figure that illustrates about the source point of two example rings of the hoop structure of article of the present invention and impact point right position;

Fig. 4 to 7 is relevant method for folding of the present invention figure in four examples; And

Fig. 8 to 12 is respectively the figure of four examples of article of the present invention.

The specific embodiment

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 the on-plane surface plane or as shown in Figure 1, and nonplanar pressed on ring 2 is positioned on basic ring 1.

Each

ring

1,2 can be made of single hoop, so this hoop structure has two different hoops.Alternatively, the single hoop that is shaped in a suitable manner can consist of 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 of the part of one of them hoop and the part of another hoop.

It can be the shape of strict circle that these

rings

1,2 present, yet this shape is more typically roughly oblong, as shown in Fig. 1 reality.

Well imagine, the ring 1 in the present invention, 2 be rendered as have at least one minor axis a1, a2 and at least one major axis A 1, A2 elongated circular the 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 the ellipse as shown in Fig. 2 A.The ring 1 be the plane or nonplanar (in this example, shown in the view of Fig. 2 A is the ring 1 of paving), so it has single minor axis (or main minor axis) a1, have relative summit s3 and s4 along main minor axis a1, and single major axis A 1(or main major axis) A1, have two relative summit s1 and s2 on this main major axis A 1.

As shown in Fig. 2 B and 2C, overall shape can also be to have the roughly thin oblong form of 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, the ring 1 can be the 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 on this main major axis A 1), and a plurality of minor axis a1, a1 ' (all having two relative summit s3, s3 ' and s4, s4 ' on each minor axis a1, a1 ').

About these minor axises a1, a1 ', the minor axis a1 that intersects 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, the ring 1 be the plane or nonplanar (in this example, shown in the view of Fig. 2 C is the ring 1 of paving), 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 a plurality of major axis A 1, A1 ' (having 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 that intersects 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 will provide has two roughly straight sides (described straight sides is parallel to any in main minor axis a1 or inferior minor axis a1 ') and another two rings of straight sides (described straight sides is parallel to any in main major axis A 1 or inferior major axis A1 ') roughly, therefore has a plurality of minor axis a1, a1 ' and a plurality of major axis A 1, A1 '.So this overall shape becomes approximate rectangular (may be square) with fillet.

Be called as roughly that oblong annular also covers roughly avette ring, as shown in Fig. 2 D.

In Fig. 2 D, the ring 1 be the plane or nonplanar (in this example, shown in the view of Fig. 2 D is the ring 1 of paving), and it has skew, minor axis a1(or main minor axis a1 that have two relative summit s3 and s4 on it left), and have major axis A 1 two relative summit s1 and s2, that consist of axis of symmetry.

More straight near the part of summit s1, and the s3 on a side and the part between s2 and the s4 on opposite side and the part between s2 more straight, this avettely more trends towards becoming the triangle with fillet.

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

Folding articles of the present invention (below will specifically describe its example with reference to Fig. 6 to Fig. 9) is characterised in that, they have for assisting folding device, and this device is used for assisting forming at least two subrings by at least one ring of the hoop structure of article.

By obtaining to form subring with folding assist device, thereby take source point to impact point, each in above-mentioned point is arranged to one of them ring along structure directly or indirectly.

However, but source point and impact point must consist of a pair of point that satisfies a certain amount of accumulation conditions, below with reference to Fig. 3 A and 3B, this are described.

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

For { the source point of discussing is described; Impact point } to necessary one of them condition that satisfies, on ring 1, source point P arbitrarily is shown _SAnd a series of impact point P _CWith a P ₂, have a few all be arranged to along the ring 1 distance that records more than or equal to 2 π R _Rupt, R wherein _RuptIt is the limit curvature radius of ring.This distance is by ring 1 expression of dotted lines.

These P _CAnd P ₂All consist of source point P _SSuitable impact point.

Yet, by the meaning of the present invention, the some P in Fig. 3 A ₁Can not consist of source point P _SImpact point because its ring 1 on along the ring 1 distance that records less than 2 π R _Rupt

Well imagine, by the meaning of the present invention, the limit curvature radius is in the situation that surpass this radius of curvature and should ring can rupture maybe and should ring can be subject to permanent deformation and can not return to the radius of curvature of its original shape, therefore this limit curvature radius depends on the material (for example glass fiber, wirerope or line) that ring uses especially, but also depends on the diameter of the rods that consists of ring.

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

In this case, by the meaning of the present invention, point is to { P ₁P ₂As putting { P ₂P ₁Equally can not consist of { source point; Impact point } right, because they are positioned on major axis A 1.

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

In addition, Fig. 3 B illustrates the concrete situation of oblong ring 1(for oval) figure, thereby 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 the plane, perhaps it can be nonplanar (the view correspondence of Fig. 3 B pave ring 1) in this example.

In this case, corresponding to { source point; Impact point } to { P of (it is suitable by the meaning of the present invention) _SP _CTo must satisfy above-mentioned with reference to Fig. 3 A describe about between them along the ring 1 identical condition of the distance that records.

Therefore, from the source point P along ring 1 location (in the upper left 1/4th of ring 1) _SBeginning, all some P _CAll suitable impact point, as long as 1 distance that records is encircled more than or equal to 2 π R in their edges on ring 1 _RuptAgain, this distance is by ring 1 expression of dotted lines.

On the contrary, still from being positioned at the source point P of (in the upper left 1/4th of ring 1) on ring 1 _SBeginning only will be put P ₁Edge ring 1 distance that records is less than 2 π R on ring 1 _Rupt, it does not consist of suitable impact point.

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

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

Therefore, in the example of Fig. 3 B, be positioned at the some P on main major axis A 1 _CWith relative point (without Reference numeral) on main major axis A 1 thereby can not consist of suitable { source point by the meaning of the present invention; 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 } right to the formed point in two relative summits that must both not correspond to main minor axis a1, the formed point in two relative summits that does not also correspond to main major axis A 1 is right.

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

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

Yet, as shown in Fig. 2 B, for having for the plane or nonplanar oblong ring 1 of a plurality of minor axis a1 ' main minor axis a1 and/or a plurality of major axis A1 ', if the inferior minor axis a1 ' that considers is obviously different from main minor axis a1, the inferior major axis A1 ' that perhaps considers is obviously different from main major axis A 1, so corresponding to the { source point on two of one of one of inferior minor axis a1 ' or inferior major axis relative summits; Impact point } to consisting of the suitable { source point 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 above-mentioned those two exceptions, another special case is about the oblong ring on plane) difficulty or the actual impossibility of one of reason and the expectation distortion that obtains ring relevant, even when above-mentioned condition about the minimum range between these two points satisfies.

What need were clear and definite is, circular or oblong non-planar curve is usually used at this paper the curve that expression represents at least one linear axis (major axis of oblong curve or minor axis), with the center tangent of curve and comprise the plane of described linear axis and at least two extreme values (these two extreme values corresponding to plane farthest the point of the distance on curve with the center tangent of curve, but never be limited to this 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 on the ground that forms with the plane of the center tangent of curve, and major axis A 1 is curve, and via passing corresponding to two extreme values of distance ground two points farthest.

For the oblong curve 2 of corresponding pressed on ring 2, minor axis a2 is straight line, and prepare forming the top that has with the tent on the plane of the center tangent of curve, principal axis A 2 is curves, and via passing corresponding to two extreme values of the positive section of distance two points farthest.

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

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

Before carrying out the method that forms two subrings, perhaps in manner of execution, come stacked ring by initial step.

At last, before folding or during folding, when in fact this structure comprised a plurality of stacking or stacked ring each other, two virtual subrings were considered to begin to form from the single virtual ring.Yet, should be clear that, so each virtual subring by single initial virtual ring corresponding to the same way as of stacked a plurality of rings corresponding to stacked a plurality of subrings.

For simplicity, the method is illustrated by the schematic diagram that only has 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, and this ring 1 has source point 5a and the impact point 6 that is marked, impose a condition more than satisfying thereon.

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

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

In order to promote this operation, can mark 6 be set at impact point 6 places, in order to need by the accurate indication of band to which point for the user provides source point 5a.

Can also provide be positioned at impact point 6 induction element formula attachment device 6(for simplicity, be still Reference numeral 6 in Fig. 4), tractive element 5 passes it and inserts in permanent or interim mode, this element is for example rigidity or flexible guiding ring type.

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

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

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

subring

1a and 1b.

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

As long as 6 beginnings of source point 5a and impact point are relative along diameter, as shown in the view of Fig. 4 (a), resulting two

subring

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, the 5b of mark thereon, { source point 5a; Impact point 6} to { source point 5b; Each of impact point 6} centering all satisfies 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, this tractive element 5 is the form of elongated flexible member 5, is for example rope 5.It can be band or simple flexible grip equally.

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

Again, easier in order to make operation, mark 6 can be arranged to be positioned at impact point 6 places, in order to provide the accurate indication of

source point

5a, 5b band to which point for the user.

The purpose of the induction element formula attachment device 6(that is positioned at impact point 6 in order to simplify can also be provided, and is still Reference numeral 6 in Fig. 5), tractive element 5 forever or provisionally passes it and inserts, and this element is for example the guiding ring type.

Should see having equally two different tractive elements, an end of each tractive element is fastened to respectively in

source point

5a, 5b, and the opposite end of two tractive elements freely supplies user's tractive.

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

The result of this operation is to make

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, then ring 1 beginning at first between source point 5a and impact point 6, secondly part 100,101 and 102 torsions of the ring 1 between source point 5b and impact point 6.

By this tractive element 5 of continuous tractive,

source point

5a, 5b continue to turn to impact point 6, and twist, in order to reach the structure shown in the view of Fig. 5 (c),

form subring

1a, 1b and 1c.

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

In this example, two

source point

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

Therefore, obtain three

subring

1a, 1b and 1c.Postulated

point

5a, 5b are initially positioned at as in the view of Fig. 5 (a) on ring 1, and the girth of subring 1c is ring 1 only about half of girth, and the girth separately of two

subring

1a, 1b is roughly the same, be about ring 1 girth 1/4th.Therefore the girth of ring 1c is about the twice of the girth of

ring

1a or 1b.

As shown in Figure 6, the preferred selecteed mode of

source point

5a, 5b is, three

subring

1a, 1b and 1c have roughly the same girth (that is, the girth of ring 1 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 the summit of main minor axis of one of summit of ring 1 main major axis and

ring

1, and 6 of impact points are positioned at the relative place, summit 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 point

5a, 5b and an impact point 6 of mark thereon, { source point 5a; Impact point 6} to { source point 5b; Impact point 6} is to all satisfying above-mentioned condition.

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

By via ring 12 tractives this tractive element 5, the user can take the source point 5a of ring 1 impact point 6 of same ring 1 to, and will encircle simultaneously 1 source point 5b and take same impact point 6 to.

Again, in order to promote operation, can mark 6 be set at impact point 6 places, in order to provide

source point

5a, 5b by with the accurate indication to which point for the user.

The purpose of induction element formula attachment device 6(in order to simplify that is arranged on impact point 6 places can also be provided, be still Reference numeral 6 in Fig. 6), tractive element 5 passes this induction element formula attachment device 6 and inserts in permanent or interim mode, and this induction element can be for example to guide ring type.

Should observe, can have in an identical manner two different tractive elements, an end of each tractive element is fastened to respectively one of

source point

5a and 5b, and the user is at its relative free end tractive.

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

The initial result of this operation is to make

source point

5a, 5b turn to impact point 6, as shown in the view of Fig. 6 (b).Secondly as shown in the curved arrow in this view, subsequently at first between source point 5a and impact point 6, the part 100,101 and 102 of the ring 1 between source point 5b and impact point 6 begins torsion.

By continuing this tractive element 5 of tractive,

source point

5a, 5b continue to turn to impact point 6, and continue to reverse, thereby reach the structure shown in the view of Fig. 6 (c), form three

subring

1a, 1b and 1c.

More accurately, reverse the part 100,101 that at first is shown as the ring 1 that is in rollover states, next is shown as the part 100,102 of the ring 1 that is 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 point

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

Therefore, obtain three

subring

1a, 1b and 1c that girth is 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, is begun and with reference to Fig. 6, more specifically as shown in the view of Fig. 6 (a) by the structure of the beginning structural similarity of describing with above example.

Therefore, hoop structure shown in Figure 7 comprises nonplanar oblong ring 1, and this ring 1 has two

source point

5a, 5b and the impact point 6 of mark thereon, { source point 5a; Impact point 6} to { source point 5b; Impact point 6} is to all satisfying above-mentioned condition.

Again, an 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, and for example rope 5, and can be made of band or simple flexible grip, perhaps comprise band or simple flexible grip.

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

As in above-mentioned example, in order to promote operation, can mark 6 be set at impact point 6 places, in order to provide

source point

5a, 5b by with the accurate indication to any point for the user.

The purpose of induction element formula attachment device 6(in order to simplify that is positioned at impact point 6 places can also be provided, be still Reference numeral 6 in Fig. 7), tractive element 5 passes this guiding piece formula attachment device 6 and inserts in permanent or interim mode, and induction element is for example to guide ring type.

Two different tractive elements can also be provided, and an end of each tractive element is fastened to respectively one of

source point

5a, 5b, and the user is at its relative free end tractive.

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

The result of this operation is to make

source point

5a, 5b initial turn point 6, as shown in Fig. 7 (b) and view 7(c).

Yet although from identical structure, in this example, the torsion of subring is not that mode by identical with above-mentioned example shown in Figure 6 occurs with forming.

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

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

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

At last, 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 above example, two

source point

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

Therefore, obtain equally girth (girth of corresponding ring 1 1/3rd) roughly the same three

subring

1a, 1b and 1c.

Should observe, three examples shown in Fig. 5 to 7 provide single target point 6, two

source point

5a and 5b, yet two different impact points can be set in the same way.So result will be three subrings equally, but they are with asymmetric and girth is different.

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

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

Therefore, tent comprises flexible sheets 3,4(it is for example made by a plurality of
