Abstract
A selferecting structure includes a frame formed by one or two flexible continuous contours of rod or tube material possessing round cross section, each contour having two figure eight loops longitudinally formed as a double figure eight type continuous contour, and sheet material extending over the frame and attached to the rod or tube material. Two flexible continuous contours will be connected together side by side, parallel to each other through four binding tube sleeves to form one foldable structure. Three fixing tube sleeves respectively placed at a crossing of rod or tube of each flexible continuous contour, where the length and the inner size of the fixing tube sleeve define the level of friction of the frame rod or tube material inside the sleeve when unfolding the structure, thus defining a safety rate of the selferecting speed.
Description
- The present invention relates to a selferecting structure and, more particular, to a multi-purpose structure made of flexible frame elements and sheet material to form different shade providing devices or antimosquito net frames.
- Structures, which are composed of one or more continuous flexible figure eight loops with fabric extending over and between sections of the loops to define a partial or full enclosure, have been developed, which can be quickly erected or collapsed. Such devices are illustrated in U.S. Pat. No. 6,302,127; U.S. Pat. No. 3,990,463, the disclosures of which are incorporated herein by reference.
- The simplest of the structures disclosed in the aforementioned patents is formed by a single FIGURE eight frame made of continuous band. Structures using this frame construction are not stable in the erected position and especially when placed on steep slopes, because of the two support points to ground and not stable frame construction at the same time (there is no enough extending (unfolding) force to keep their construction steady upright). This is because the continuous band of which their frame is made does not have the possibility to accumulate much unfolding power when folded. Folding these structures by coiling is not too easy, because of the big diameter of their loops. Unfolding of those structures is not fully independent. The next structure is formed by a single FIGURE eight frame made of continuous material with preferably asymmetric cross section. However “Round or square tubing or solid stock, while less preferred, can also be employed.” If so the structures using this frame are not stable in the erected position too, because they have two support points to ground and not steady construction at the same time, due to the big diameter of the loops of the frame (that is why they are not preferred—a frame constructed of a material with round cross section can not possess big loops and be steady at the same time). Folding here is not easy, because of the same big diameter of the loops. Unfolding can be at dangerous rates. There is a structure, that is constructed by two figure eight frames, placed at a distance from each other, but the separate frames are not connected steady and firmly between them in one rigid frame and so need additional strengthening, tightening and fastening elements like pegs, ropes and fabric as a linking element to keep the structure upright. Folding is heavy and unfolding could be dangerous if the frames have a round cross section and thus a big unfolding force.
- The present invention is directed to a structure including a frame, formed of one or two continuous contours made of rod or tube material possessing round cross section, each including two figure eight loops, selfconnected on their longitudinal axis one after another (hereafter referred as a double figure eight type continuous contours), to form one rigid structure, covered by sheet material, extending over loops and sewed to the rod material. The places of the crossings of the rod or tube material are accumulating the energy, when folded, that is needed for the unfolding of the structure. In the places of the crossings of the rod or tube material are placed with fixing tube sleeves, having the role to define the rate of the unfolding speed.
- The advantages of thus presented invention are because of the use of one or two contours in the form of double figure eight formations of flexible rod or tube material, alone or connected together side by side, parallel to each other by the means of the binding tube sleeves and with the help of the sheet material on them, form a rigid and stable construction with huge extending (unfolding) force, keeping them steady and having two or four support points to ground. The inner useful space is enlarged and the space, needed when in folded position, is low to a level, that they can be placed in a personal bag. Folding is easy, because of the smaller diameter of the loops. Unfolding is fully automatic and its speed is kept in a safety limits by the means of the fixing tube sleeves positioned at a crossing of two adjacent round rods or tubes of the flexible continuous contour.
- Accordingly, the present invention is to provide an improved structure, defined by a frame of one or two selfconnected continuous double figure eight type contours, composed of crossed rod material and sheet material, extending over the loops. Other and further objects and advantages will appear hereinafter.
- It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the invention as claimed.

- Referring to
FIGS. 1 , 2 and 3, the frame of one preferred embodiment for the present selferecting structure 1 is constructed with onecontour 3 made of flexible continuous rod material with round cross section and asheet material 2 extends over the frame and attached to thecontour 3. Thecontour 3 includes two figure eight loops longitudinally formed as a double figure eight type contour. Afixing tube sleeve 4 is placed on the crossing of two adjacent round rods, which pass through thesleeve 4 crosswise as shown inFIG. 4 , so that the rate of automatic unfolding speed of the selferecting structure 1 is defined. Actually, the length and the inner size of thefixing tube sleeves 4 define the level of friction of the frame rod material inside thosesleeves 4 when unfolding the structure. The structure 1 is folded by folding the continuous contour in the middle and the two such formed figure eight loops are folded in the middle again to form a hoop. Then the one end of thus formed hoop is twisted 180 degrees relative to the other end and now formed figure eight loops are folded in the middle to form a hoop. Thus folded structure is placed in a bag possessing similar dimensions. The structure unfolds automatically when pulled out of the containing bag. - Referring to
FIGS. 5 , 6 and 7, the frame of another preferred embodiment for the present selferecting structure 1 is constructed with twocontours 3 made of flexible continuous round rod and asheet material 2 extends over the frame and attached to thecontour 3. Eachcontour 3 includes two figure eight loops longitudinally formed as a double figure eight type contour. The twocontours 3 are arranged side by side to be connected together in parallel by means of fourbinding tube sleeves 5 as shown inFIG. 9 . Similarly, eachcontour 3 includes two figure eight loops longitudinally formed as a double figure eighttype contour 3. Thefixing tube sleeve 4 is placed on the crossing of two adjacent round rods of thecontinuous contour 3, which pass through thesleeve 4 crosswise as shown inFIG. 8 , so that the rate of automatic unfolding speed of the selferecting structure 1 is defined. Actually, the length and the inner size of thesleeves 4 define the level of friction of the frame rod material inside thosesleeves 4 when unfolding the structure. The structure 1 is folded by folding in the middle the contour nearest to the door opening 25, then folding it over the second contour and the four thus formed figure eight loops are folded in the middle again to form a hoop. Then the one end of thus formed hoop is twisted 180 degrees relative to the other end and now the formed figure eight loops are folded in the middle to form a hoop. Thus folded structure is placed in a bag possessing similar dimensions. The structure unfolds automatically when pulled out of the containing bag. - The structures of this invention are useful as tents, shelters, sunshade covers.
- Thus, improved selferecting structures with greater stability, improved form, easy folding and fully automatic unfolding are disclosed. While embodiments and applications of this invention have been disclosed, it would be apparent to those, skilled in the art, that many more modifications are possible without departing from the inventive concepts herein. The invention, therefore is not to be restricted, except in the spirit of the appended claims.
