Definitions
- the present invention relates generally to collapsible structures and specifically to a collapsible container for convenient storage and transportation of items.
- the present invention has numerous applications including container, play structure, and shelter.
- a typical household often encounters the need for temporary storage of garments prior to washing or cleaning. Regardless of the place where laundry or cleaning is done, either at home or in a commercial setting, soiled garments need to be sorted, stored, and eventually transported to a designated place.
- the present invention can be utilized for garment sorting, storage and transportation.
- the present invention can also be utilized as an organizer for various objects.
- the present invention may be used to organize objects normally found in the trunk of a car.
- the present invention can also be used for other purposes, such as the storage or transportation of toys or other objects.
- the present invention could be used as a child's play structure or pet den structure. Accordingly, its use is multipurpose as both a container and structure.
- U.S. Pat. No. 2,625,973 to Weldon et al. teaches a laundry hamper comprising a rectangular frame having upper and lower portions that telescope within one another in a detachable manner.
- the lower portion includes a base frame, while the upper portion comprises a top frame.
- a cover is secured by a hinge to the top frame and an outer bag surrounds the rectangular frame.
- a plurality of small inner bags are provided within the outer bag.
- U.S. Pat. No. 1,581,888 to Thomas discloses a collapsible receptacle comprising two rectangular wire frames, hingedly secured together, means for holding the frames to form a triangularly shaped structure, and a fabric portion covering the frames and providing an enclosure.
- the present invention solves the above-mentioned shortcomings and provides a convenient, easy to manipulate, and ergonomic means for storing or transporting garments or other objects.
- U.S. Pat. No. 6,539,895 to Hoagland teaches a portable pet carrier having a top portion, a middle section and a bottom portion made primarily from a molded synthetic material, with the top portion having a handle-like structure for carrying the assembled pet carrier and the middle portion having holes for ventilation and a door or window-like structure for placing a pet in or removing a pet from the carrier.
- Other pet enclosures are known in the art to be collapsible. These devices commonly have a square footprint and a domed configuration, which creates a pet enclosure that is larger than necessary because of unutilized space. As the size of the enclosure increases, its cost increases and its integrity decreases.
- the present invention relates generally to a collapsible structure and specifically to a collapsible structure for storing articles or forming a child's toy and method of making and using the same.
- each side panel comprises a flexible continuous loop frame, a web of material, and an edging material.
- the edging envelops the frame and is coupled to the periphery of the web.
- the floor panel is attached to the bottom side of each side panel thus forming the structure.
- each side panel is attached to a side panel separator, which in turn is connected to the next adjacent side panel.
- the floor panel is attached to both the bottom side of each side panel and to the side panel separators, thus providing means for holding articles within the structure and for supporting the structure in its expanded state.
- a single frame member forms the frame structure for two side panels.
- Each side panel comprises a web of material and an edging material.
- the edging material is attached to portions of the web.
- the edging partially envelops the frame and is coupled to predetermined portions of the periphery of the web.
- the floor panel is attached to the bottom side of each side panel, thus forming the structure.
- At least one handle member is coupled to opposite side panels at the open top of the structure.
- the handle may be coupled to only one side panel or may be an aperture formed within one or more of the side panels.
- the edging may be attached to portions of the frame and the handle may be coupled to or looped around the frame at a portion not including edging.
- an optional storage pouch may be coupled to one of the side panels at the open top of the structure.
- the present invention is easily collapsed into a compact state and the pouch allows storage of the structure in its collapsed, compact state.
- the collapsible structure further comprises a divider panel, the divided panel being attached to diagonally opposite edgings of the side panels.
- the collapsible structure further comprises at least two divider panels, preferably arranged substantially parallel to each other and being coupled to opposite side panels to create at least three separate compartments within the structure.
- each side panel comprises a flexible, continuous loop frame, and a two-ply web of material.
- the loop frame is captured between the two layers of web material comprising the two-ply web.
- the floor panel is attached to the bottom side of each side panel, thus forming the structure.
- at least one handle member may be coupled to opposite side panels at the open top of the structure.
- the handle may be coupled to only one side panel or may be an aperture formed within one or more of the side panels.
- the two-ply embodiment may further include an optional storage pouch for receiving the structure in the collapsed state for storage.
- a preferred method of manufacturing the collapsible structure includes the steps of attaching each handle member to a side of two opposite webs.
- the edging is next coupled to each web such that the edging surrounds the perimeter of the web and forms a channel or pocket through which the frame will later be inserted.
- each side of the floor panel is attached to the bottom side of each side panel.
- a side of each side panel is connected with a side of an adjacent side panel.
- the frame for each side panel is inserted through the channel formed by each edging.
- the ends of each frame member are connected, preferably using a crimped butt connector, to give the collapsible structure its ability to freely stand in a rigid, expanded, upright state.
- the edging may be non-continuous to allow the handle members to be attached to or looped around the frame member at a non-continuous gap in the edging.
- An alternative method of manufacturing the collapsible structure includes the steps of supplying two attached webs of material. Next, edging is coupled to each web such that the edging substantially surrounds the perimeter of each web and forms a channel or pocket through which the frame will later be inserted. An opening in the edging is left along the respective sides where the two webs are contiguous. A two-web side panel is thus formed. After a pair of two-web side panels have been formed, a single frame is inserted through the channel formed by the edging of each two-web side panel. Each frame first is threaded through the edging surrounding one web and then is threaded through the edging surrounding the second, contiguous web.
- each frame member is connected, preferably using a crimped butt connector, in a “figure eight” configuration to give the collapsible structure its ability to freely stand in a rigid, expanded, upright state.
- the second two-web side panel is completed by the same steps. The pair of two-web side panels are connected together and a floor panel is attached along the lower edge of each side panel.
- Yet another alternative method of manufacturing the collapsible structure includes the steps of attaching each handle member to a side of two opposite webs. Coupling the edging to each web such that the edging surrounds the perimeter of the web and forms a channel or pocket through which the frame will later be inserted. After the requisite number of side panels has been formed, each corner of the floor panel is attached to one end of each side panel separator. Next each side panel is connected with one side of the floor panel and with two adjacent side panel separators. The frame for each side panel is inserted through the channel formed by each edging. The ends of each frame member are connected, preferably using a crimped butt connector, to give the collapsible structure its ability to freely stand in a rigid, expanded, upright state.
- the edging may be non-continuous to allow the handle members to be attached to or looped around the frame at a non-continuous gap in the edging.
- Yet another alternative method of manufacturing the collapsible structure includes the step of first joining two webs together leaving a small opening for receiving the continuous loop frame member. This forms a side panel. The requisite number of side panels are formed and attached along their side edges. Next, each side of a floor panel is attached to the bottom side of each side panel. The frame for each side panel is inserted through the small opening. Finally the opening is closed. Optionally, one or more handles may be attached to or formed in the side panel, frame or both.
- the first step comprises attaching the first web to the second web along their outer peripheries to form a side panel.
- the requisite number of side panels are formed and attached along their side edges.
- each side of a floor panel is attached to the bottom side of each side panel.
- the frame for each side panel is inserted into the peripheral opening formed between the first and second webs.
- one or more handles may be attached to or formed in the side panel, frame or both.
- the structure can be folded and collapsed for storage or transportation.
- the preferred steps of collapsing the structure include grasping opposite corners of the floor panel and biasing one corner toward the other until all side panels are adjacent and overlay each other.
- the structure is now partially collapsed but each side panel is still in an expanded state.
- the optional handle members and the floor panel are inserted in between any two of the adjacent overlaying side panels.
- the structure will form three overlaying circular loops folded adjacently.
- the three overlaying loops may be placed into an optional storage pouch. The pouch prevents the structure from springing back into its fully expanded condition.
- the three overlaying loops may be maintained in the collapsed state by way of an elastic band or other retaining device.

No. 09/393,956 filed on 10 Sep. 1999 now abandoned, which is a continuation-in-part of U.S. patent Parent application Ser. No. 09/108,521 filed on 1 Jul. 1998 that has since issued to U.S. Pat. No. 5,971,188, now RE37,924 issued 10 Dec. 2002; the pending application and the issued patents are commonly owned by the assignee hereof.
- The present invention relates generally to collapsible structures and specifically to a collapsible container for convenient storage and transportation of items.
- The present invention has numerous applications including container, play structure, and shelter. A typical household often encounters the need for temporary storage of garments prior to washing or cleaning. Regardless of the place where laundry or cleaning is done, either at home or in a commercial setting, soiled garments need to be sorted, stored, and eventually transported to a designated place. The present invention can be utilized for garment sorting, storage and transportation. The present invention can also be utilized as an organizer for various objects. For example, the present invention may be used to organize objects normally found in the trunk of a car. Alternatively, the present invention can also be used for other purposes, such as the storage or transportation of toys or other objects. Further yet, the present invention could be used as a child's play structure or pet den structure. Accordingly, its use is multipurpose as both a container and structure.
- Numerous devices are known in the art to provide effective storage of soiled garments, for example laundry baskets, conventional hampers, or clothing bags. For example, U.S. Pat. No. 2,625,973 to Weldon et al. teaches a laundry hamper comprising a rectangular frame having upper and lower portions that telescope within one another in a detachable manner. The lower portion includes a base frame, while the upper portion comprises a top frame. A cover is secured by a hinge to the top frame and an outer bag surrounds the rectangular frame. A plurality of small inner bags are provided within the outer bag. U.S. Pat. No. 1,581,888 to Thomas discloses a collapsible receptacle comprising two rectangular wire frames, hingedly secured together, means for holding the frames to form a triangularly shaped structure, and a fabric portion covering the frames and providing an enclosure.
- However, all these prior art devices are voluminous in their expanded state, are uneasy to fold or collapse, are still relatively voluminous in their collapsed state, and are difficult to manipulate. The present invention solves the above-mentioned shortcomings and provides a convenient, easy to manipulate, and ergonomic means for storing or transporting garments or other objects.
- Other devices are known in the art to be collapsible structures. For example, U.S. Pat. No. 5,560,385 to Zheng teaches a collapsible play structure. This device forms a large cubicle that children can crawl through. However, each cube of the Zheng device utilizes three (3) frame members, preferably four members, to achieve structural integrity. The present invention may be practiced with as few as two frame members.
- Additionally, devices are known in the art to provide an enclosure or structure for temporarily containing or for transporting a pet or other objects. For example, U.S. Pat. No. 6,539,895 to Hoagland teaches a portable pet carrier having a top portion, a middle section and a bottom portion made primarily from a molded synthetic material, with the top portion having a handle-like structure for carrying the assembled pet carrier and the middle portion having holes for ventilation and a door or window-like structure for placing a pet in or removing a pet from the carrier. Other pet enclosures are known in the art to be collapsible. These devices commonly have a square footprint and a domed configuration, which creates a pet enclosure that is larger than necessary because of unutilized space. As the size of the enclosure increases, its cost increases and its integrity decreases.
- All these prior art pet enclosures are voluminous in their expanded state, are either non-collapsible or are uneasy to fold or collapse, are still relatively voluminous in their collapsed state, and are difficult to manipulate. These configurations require more space, consume more materials, and require stronger collapsible framing than are necessary to efficiently contain or transport a pet or other objects. The present invention solves the above-mentioned shortcomings and provides a convenient, easy to manipulate, and more efficiently sized ergonomic enclosure for containing and transporting pets or other objects, and is adaptable for use in most weather conditions.
- The present invention relates generally to a collapsible structure and specifically to a collapsible structure for storing articles or forming a child's toy and method of making and using the same.
- According to the present invention, the foregoing and other advantages are obtained by providing a collapsible structure comprising a plurality of side panels and a floor panel forming an enclosure having an open top. In the preferred embodiment, each side panel comprises a flexible continuous loop frame, a web of material, and an edging material. The edging envelops the frame and is coupled to the periphery of the web. The floor panel is attached to the bottom side of each side panel thus forming the structure.
- In an alternative embodiment, each side panel is attached to a side panel separator, which in turn is connected to the next adjacent side panel. The floor panel is attached to both the bottom side of each side panel and to the side panel separators, thus providing means for holding articles within the structure and for supporting the structure in its expanded state.
- In another alternative embodiment, a single frame member forms the frame structure for two side panels. Each side panel comprises a web of material and an edging material. The edging material is attached to portions of the web. The edging partially envelops the frame and is coupled to predetermined portions of the periphery of the web. The floor panel is attached to the bottom side of each side panel, thus forming the structure.
- In accordance with an aspect of the invention, at least one handle member is coupled to opposite side panels at the open top of the structure. Alternatively, the handle may be coupled to only one side panel or may be an aperture formed within one or more of the side panels. In yet another variation, the edging may be attached to portions of the frame and the handle may be coupled to or looped around the frame at a portion not including edging.
- In accordance with another aspect of the invention, an optional storage pouch may be coupled to one of the side panels at the open top of the structure. The present invention is easily collapsed into a compact state and the pouch allows storage of the structure in its collapsed, compact state.
- In another alternative embodiment, the collapsible structure further comprises a divider panel, the divided panel being attached to diagonally opposite edgings of the side panels. In yet another alternative embodiment, the collapsible structure further comprises at least two divider panels, preferably arranged substantially parallel to each other and being coupled to opposite side panels to create at least three separate compartments within the structure.
- In yet another embodiment, each side panel comprises a flexible, continuous loop frame, and a two-ply web of material. The loop frame is captured between the two layers of web material comprising the two-ply web. The floor panel is attached to the bottom side of each side panel, thus forming the structure. Similarly to previously mentioned embodiments, at least one handle member may be coupled to opposite side panels at the open top of the structure. Alternatively, the handle may be coupled to only one side panel or may be an aperture formed within one or more of the side panels. Further, and as discussed in conjunction with previously mentioned embodiments, the two-ply embodiment may further include an optional storage pouch for receiving the structure in the collapsed state for storage.
- A preferred method of manufacturing the collapsible structure includes the steps of attaching each handle member to a side of two opposite webs. The edging is next coupled to each web such that the edging surrounds the perimeter of the web and forms a channel or pocket through which the frame will later be inserted. After the requisite number of side panels has been formed, each side of the floor panel is attached to the bottom side of each side panel. Next, a side of each side panel is connected with a side of an adjacent side panel. The frame for each side panel is inserted through the channel formed by each edging. The ends of each frame member are connected, preferably using a crimped butt connector, to give the collapsible structure its ability to freely stand in a rigid, expanded, upright state. Optionally, the edging may be non-continuous to allow the handle members to be attached to or looped around the frame member at a non-continuous gap in the edging.
- An alternative method of manufacturing the collapsible structure includes the steps of supplying two attached webs of material. Next, edging is coupled to each web such that the edging substantially surrounds the perimeter of each web and forms a channel or pocket through which the frame will later be inserted. An opening in the edging is left along the respective sides where the two webs are contiguous. A two-web side panel is thus formed. After a pair of two-web side panels have been formed, a single frame is inserted through the channel formed by the edging of each two-web side panel. Each frame first is threaded through the edging surrounding one web and then is threaded through the edging surrounding the second, contiguous web. The ends of each frame member are connected, preferably using a crimped butt connector, in a “figure eight” configuration to give the collapsible structure its ability to freely stand in a rigid, expanded, upright state. The second two-web side panel is completed by the same steps. The pair of two-web side panels are connected together and a floor panel is attached along the lower edge of each side panel.
- Yet another alternative method of manufacturing the collapsible structure includes the steps of attaching each handle member to a side of two opposite webs. Coupling the edging to each web such that the edging surrounds the perimeter of the web and forms a channel or pocket through which the frame will later be inserted. After the requisite number of side panels has been formed, each corner of the floor panel is attached to one end of each side panel separator. Next each side panel is connected with one side of the floor panel and with two adjacent side panel separators. The frame for each side panel is inserted through the channel formed by each edging. The ends of each frame member are connected, preferably using a crimped butt connector, to give the collapsible structure its ability to freely stand in a rigid, expanded, upright state. Optionally, the edging may be non-continuous to allow the handle members to be attached to or looped around the frame at a non-continuous gap in the edging.
- Yet another alternative method of manufacturing the collapsible structure includes the step of first joining two webs together leaving a small opening for receiving the continuous loop frame member. This forms a side panel. The requisite number of side panels are formed and attached along their side edges. Next, each side of a floor panel is attached to the bottom side of each side panel. The frame for each side panel is inserted through the small opening. Finally the opening is closed. Optionally, one or more handles may be attached to or formed in the side panel, frame or both.
- In the alternative embodiment where the first web is continuous and non-interrupted and the second web has an annular configuration, the first step comprises attaching the first web to the second web along their outer peripheries to form a side panel. Next, the requisite number of side panels are formed and attached along their side edges. Next each side of a floor panel is attached to the bottom side of each side panel. The frame for each side panel is inserted into the peripheral opening formed between the first and second webs. Again optionally, one or more handles may be attached to or formed in the side panel, frame or both.
- From the expanded state, the structure can be folded and collapsed for storage or transportation. The preferred steps of collapsing the structure include grasping opposite corners of the floor panel and biasing one corner toward the other until all side panels are adjacent and overlay each other. The structure is now partially collapsed but each side panel is still in an expanded state. Next, the optional handle members and the floor panel are inserted in between any two of the adjacent overlaying side panels. By rotating two opposite corners of the flattened, overlaying side panels in opposite directions while biasing the two corners toward each other, the structure will form three overlaying circular loops folded adjacently. Finally, the three overlaying loops may be placed into an optional storage pouch. The pouch prevents the structure from springing back into its fully expanded condition. Alternatively, the three overlaying loops may be maintained in the collapsed state by way of an elastic band or other retaining device.
- In yet another embodiment, the collapsible structure is preferably an enclosure being rectangular in shape and comprises a top panel, a bottom panel, two side panels, a front panel having a door, and a rear panel. The top panel, bottom panel, two side panels, front panel, and rear panel are connected to one another to form a substantially rectangular enclosure having the door for ingress and egress. The top panel, bottom panel, and two side panels each comprises a flexible, continuous loop frame, a web of material, and an edging material. The edging envelops the frame and is coupled to the periphery of the web. The top and bottom web preferably comprises a web being continuous and non-interrupted. Each side panel web preferably comprises a web being a continuous and non-interrupted mesh material. The front panel is attached to the front side of the top panel, bottom panel, and two side panels. The door is preferably a square shaped cutout in the front panel, and includes a hinged edge and a zipper, although other shapes and other conventional securing means may be used. The rear panel is attached to the rear side of the top panel, bottom panel, and two side panels, thus forming the enclosure.
- In an alternative embodiment, each of the top panel, bottom panel, and two side panels are attached to a side panel separator, which in turn is connected to the next adjacent panel. The front panel is attached to both the front side of the top panel, bottom panel, and two side panels, and to the side panel separators. The rear panel is attached to both the rear side of the top panel, bottom panel, and two side panels, and to the side panel separators, thus providing means for holding pets or other objects within the enclosure and for supporting the enclosure in its expanded state.
- Similarly to previously mentioned embodiments, at least one handle member may be coupled to an edge or edges of the top panel or side panels. Alternatively, the handle may be coupled to only one side panel or may be an aperture formed within one or more of the side panels or top panel. In yet another variation, the edging may be attached to portions of the frame and the handle may be coupled to or looped around the frame at a portion not including edging. However, it should be noted handle members are not required to practice the present invention. Further, and as discussed in conjunction with previously mentioned embodiments, these embodiments may further include an optional storage pouch for receiving the enclosure in the collapsed state for storage.
- (2 Ply Closed and 2 Ply Stitched)
- In yet another embodiment, each of the top panel, bottom panel, and two side panels comprises a flexible, continuous loop frame, and a two-ply web of material. The loop frame is captured between the two layers of web material comprising the two-ply web. The front panel is attached to the front side of the top panel, bottom panel, and two side panels. The rear panel is attached to the rear side of the top panel, bottom panel, and two side panels, thus forming the enclosure

The top and bottom two-ply web preferably include a first layer being continuous and non-interrupted and having a closable opening sized for insertion and removal of the loop frame, and a second layer being continuous and non-interrupted. Each side panel two-ply web preferably includes a first layer being annular in shape having a closable opening and a second web being a continuous and non-interrupted mesh material. The loop frame is releasibly captured between the two layers of web material comprising the two-ply web. The front panel is attached to the front side of the top panel, bottom panel, and two side panels. The door is preferably a square shaped cutout in the front panel, and includes a hinged edge and a zipper, although other conventional securing means may be used. The rear panel is attached to the rear side of the top panel, bottom panel, and two side panels, thus forming the enclosure.
- Similarly to the previously mentioned embodiments, at least one handle member may be coupled to an edge or edges of the top panel or side panels. Alternatively, the handle may be coupled to only one side panel or may be an aperture formed within one or more of the side panels or top panel, by way of non-limiting example. However, it should be noted handle members are not required to practice the present invention. Further, and as discussed in conjunction with previously mentioned embodiments, the two-ply embodiments may further include an optional storage pouch for receiving the enclosure in the collapsed state for storage.
- Summary Methods
- Method W/Sleeve
- A preferred method of manufacturing the collapsible enclosure includes the steps of attaching each handle member to a side of two opposite webs. The edging is next coupled to each web such that the edging surrounds the perimeter of the web and forms a channel or pocket through which the frame will later be inserted. After the top panel, bottom panel, and two side panels have been formed, each side of the rear panel is releasibly attached to the rear side of the top panel, bottom panel, and two side panels. Next, a side of the top panel, bottom panel, and two side panels is releasibly connected with a side of each adjacent panel. Next, each side of the front panel is releasibly attached to the front side of the top panel, bottom panel, and two side panels. The frame for the top panel, bottom panel, and two side panels is inserted through the channel formed by each edging. The ends of each frame member are connected, preferably using a crimped butt connector, to give the collapsible enclosure its ability to freely stand in a rigid, expanded, upright state. Optionally, the edging may be non-continuous to allow the handle members to be attached to or looped around the frame member at a non-continuous gap in the edging. Additionally, an optional storage pouch for receiving the enclosure in the collapsed state for storage may be releasibly attached to any of the panels.
- Method W/Separators
- Yet another alternative method of manufacturing the collapsible enclosure includes the steps of attaching each handle member to a side of two opposite webs. Coupling the edging to each web such that the edging surrounds the perimeter of the web and forms a channel or pocket through which the frame will later be inserted. After the top panel, bottom panel, and two side panels have been formed, each corner of the rear panel is releasibly attached to the rear end of each side panel separator. Next, each of the top panel, bottom panel, and two side panels are releasibly connected with one side of the rear panel and with two adjacent side panel separators. Next, each corner of the front panel is releasibly attached to the front end of each side panel separator. Next, the front side of each of the top panel, bottom panel, and two side panels are releasibly connected with the front side of the front panel and with two adjacent side panel separators. The frame for the top panel, bottom panel, and two side panels are each inserted through the channel formed by each edging. The ends of each frame member are connected, preferably using a crimped butt connector, to give the collapsible enclosure its ability to freely stand in a rigid, expanded, upright state. Optionally, the edging may be non-continuous to allow the handle members to be attached to or looped around the frame at a non-continuous gap in the edging. Additionally, an optional storage pouch for receiving the enclosure in the collapsed state for storage may be releasibly attached to any of the panels.
-
Method 2 Ply Closed - Yet another alternative method of manufacturing the collapsible structure includes the step of first joining two webs together leaving a small opening for receiving the continuous loop frame member. This forms one of the top panel, bottom panel, and two side panels. The requisite number of panels are formed and attached along their side edges. Next, each side of a rear panel is attached to the rear side of the top panel, bottom panel, and two side panels. Next, a side of the top panel, bottom panel, and two side panels is releasibly connected with a side of each adjacent panel. Next, each side of a front panel is attached to the front side of the top panel, bottom panel, and two side panels. The frame for the top panel, bottom panel, and two side panels are inserted through the small opening. Finally the opening is closed. Optionally, one or more handles may be attached to or formed in any of the top panel, side panels, or frame, or any combination. Additionally, an optional storage pouch for receiving the enclosure in the collapsed state for storage may be releasibly attached to any of the panels.
- In an additional alternative step, frame stitching may be applied preferably substantially parallel to the frame and may comprise a pair of substantially parallel stitch lines.
-
Method 2 Ply w/Openings - In the alternative embodiment where the top and bottom two-ply web preferably include a first layer being continuous and non-interrupted and having a closable opening sized for insertion and removal of the loop frame, and a second layer being continuous and non-interrupted, and each side panel two-ply web preferably includes a first layer being annular in shape having a closable opening and a second layer being a continuous and non-interrupted mesh material, the first step comprises attaching the first layer to the second layer along their outer peripheries to form each panel. Next, the requisite number of panels are formed and releasibly attached along their side edges. Next each side of a front panel is releasibly attached to the front side of the top and bottom panels and each side panel. Next each side of a rear panel is releasibly attached to the rear side of the top and bottom panels and each side panel. The frame for each panel is releasibly inserted into the peripheral opening formed between the first and second layers. Again optionally, one or more handles may be attached to or formed in any of the top panel, side panels, and frame. Additionally, an optional storage pouch for receiving the enclosure in the collapsed state for storage may be releasibly attached to any of the panels.
- Summary Steps of Collapsing
- From the expanded state, the enclosure can be folded and collapsed for storage or transportation. The preferred steps of collapsing the enclosure include grasping opposite corners of the rear panel or front panel and biasing one corner toward the other until the top panel, bottom panel, and two side panels are adjacent and overlay each other. The enclosure is now partially collapsed but the top panel, bottom panel, and two side panels each are still in an expanded state. Next, the optional handle members and the rear panel and front panel are inserted in between any two of the adjacent overlaying expanded panels. By rotating two opposite corners of the flattened, overlaying panels in opposite directions while biasing the two corners toward each other, the enclosure will form three overlaying circular loops folded adjacently. Finally, the three overlaying loops may be placed into an optional storage pouch. The pouch prevents the enclosure from springing back into its fully expanded condition. Alternatively, the three overlaying loops may be maintained in the collapsed state by way of an elastic band or other retaining device.

- The present invention, a
collapsible structure 10, is illustrated inFIGS. 1 through 4 . - As shown in
FIG. 4 , thestructure 10 comprises fourrectangular side panels 20, afloor panel 50, and twohandles floor panels - Referring to
FIGS. 1 and 2 , eachside panel 20 further comprises aframe 22, aweb 24, and an edging 26. Theframe 22 is flexible, preferably formed from a sufficiently stiff yet resilient material such as spring steel wire or plastic, and is contained within the channel orpocket 25 formed by the edging 26 (best seen inFIGS. 6 b and 24 b). Theframe 22 forms a continuous loop. Preferably, theframe 22 has a rectangular cross-section, but a material with a different geometric cross-section can be used. Theweb 24 is a flexible foldable material, such as nylon cloth or nylon mesh, but can be any suitably flexible material. The nylon, or other flexible material, may be solid or perforated. The perimeter of theweb 24 is stitched to the edging 26 such that the edging 26 forms apocket 25 about the periphery of theweb 24. The edging 26 is a foldable, but stretch-resistant material capable of housing theframe 22 within itspocket 25. The edging 26 has two ends 27 and 29. - A
seam cover 28, also made out of a foldable stretch-resistant material, may be provided to cover theends frame 22 from escaping out of the edging 26. As shown inFIG. 1 , theseam cover 28 is also stitched to theweb 24. - As shown in
FIG. 3 , thefloor panel 50 is also a foldable web of material and has a generally rectangular shape. Thefloor panel 50 has fourcorner sections perpendicular sides side panel 20. Thefloor panel 50 provides means for holding the garments or other objects (not shown) within thestructure 10 and for supporting thestructure 10 in its expanded state. - Referring now to
FIGS. 5-8 , one embodiment of thecollapsible structure 10 is shown. This embodiment includesside panel separators 40 located between eachside panel 20. However, it should be noted that theside panel separators 40 are not required to practice the present invention. Theside panel separators 40 are shown to be substantially longitudinal, each including anend 42 attached preferably by means of stitching to one of thecorner sections floor panel 50. Theother end 44 of eachseparator 40 corresponds to theopen top 16 of thestructure 10. Theside panel separators 40 are preferably formed from a stretch-resistant material similar to the material used for the seam covers 28 or the edging 26. - As shown in
FIG. 6A , each rectangularly-shapedside panel 20 includes atop side 32 corresponding to theopen top 16 of thestructure 10, afloor side 34 attached to one of thesides floor panel 50, and twolateral sides FIG. 6A , eachlateral side side panel separator 40 adjacent to theside panel 20. - As depicted in
FIGS. 4 and 8 , thehandles top side 32 of two opposingside panels 20. Thehandles FIGS. 4 and 8 . Several alternative embodiments are shown inFIGS. 9 through 12 , illustrating different handle members. InFIG. 9 , thehandle members FIG. 10 depicts an alternative embodiment wherein thehandle members webs 24 of twoopposite side panels 20. InFIG. 11 , onehandle member 60 is shown as a strap coupled to diagonally opposedside seam separators 40. InFIG. 12 , thehandles webs 24 of twoopposite side panels 20. - As shown in
FIG. 13 , anoptional storage pouch 70 may be formed from a foldable material, such as nylon mesh, and stitched to theside 32 of one of theside panels 20. Thestorage pouch 70 is dimensioned to accommodate thestructure 10 in its collapsed state as later described. - Although stitching is presented as the preferred means for attaching or connecting the elements of the
structure 10 and permitting relatively convenient folding of thestructure 10, it is to be understood that other methods of attachment can be used in this invention. Such other methods may include heat sealing, gluing and the like. Accordingly, construction of the collapsible structure should not be limited to stitching alone. -
FIGS. 14 through 17 depict an alternative embodiment of thecollapsible structure 12. Thestructure 12 further includes adivider panel 80.Divider panel 80 is connected to oppositeside seam separators 40 thereby dividing the interior of thestructure 12 into two separate chambers. - FIGS. 18 to 21 show a second alternative embodiment of the
collapsible structure 14. Thestructure 14 comprises sixside panels 20 and twodivider panels divider panels divider panel sides webs 24 of twoopposite side panels 20. Thedivider panels structure 14 into three separate compartments for improved sorting and storage of objects. - FIGS. 22 to 30 show various stages in the manufacturing process of the preferred embodiment of
collapsible structure 10. Referring toFIGS. 22A and 22B , the step of stitching thehandle 60 to thetop side 32 of two (2) of thewebs 24 is shown. Specifically, the stitching is shown at 90. - In
FIG. 23 , aseam cover 28 is partially stitched toside 21 of each of the four (4)webs 24. In the two (2)webs having handles seam cover 28 is placed and sewn opposite to thehandle side 21 and includes a flap or unstitched portion, but it is to be understood that it could be placed anywhere on any side of each of thewebs 24. Referring now toFIG. 24B , the edging 26 is then folded in a channel-like fashion around the periphery of theweb 24 and stitched to theweb 24, surrounding the perimeter of theweb 24. The stitching is shown at 30. The stitched edging 26 forms apocket 25 around the periphery of eachweb 24. In the preferred embodiment, eachstructure 10 requires four (4)webs 20. The two (2) sides including theweb 24, edging 26 and seam cover 28 are shown inFIG. 24 a and the two (2) sides including thehandle 60,web 24, edging 26 and seam cover 28 are shown inFIG. 25 . Stitching of each edging 26 starts and ends at theseam cover 28, thereby leaving a small space between ends 27 and 29 of each edging 26. - In
FIGS. 26A and 26B , the next step involves stitching eachcorner section floor panel 50 to theend 42 of eachside panel separator 40. The stitching is shown at 46. Now referring toFIGS. 27 and 28 , the step of attaching each of the fourside panels 20 by means of stitching to thefloor panel 50 and theside panel separators 40 is shown. The two (2)side panels 20 containing thehandles handles floor side 34 of each of theside panels 20 is stitched to one of thesides floor panel 50 as shown inFIG. 23 . Still referring toFIG. 23 , next the lateral sides 36 of each of theside panels 20 is stitched to the corresponding adjacentside panel separator 40. As shown inFIG. 28 , once the firstlateral side 36 of aside panel separator 40 is stitched on one side, the secondlateral side 38 of anotherside panel separator 40 is stitched to the other side. The resultingenclosure 92 is shown inFIG. 29 . - As discussed previously, the
structure 10 may be constructed without theside panel separators 40. In constructing the embodiment withoutside panel separators 40, the two (2)side panels 20 containing thehandles handles floor side 34 of each of theside panels 20 is stitched to one of thesides floor panel 50. Next the lateral sides 36, 38 of each of theside panels 20 are stitched to anadjacent side panel 20 thus forming thestructure 10 having an open top 16. - The final steps of the manufacturing process of the present invention involve inserting the
frame 22 in one of the open ends 27 or 29 of each of theedgings 26 as shown inFIG. 30 . Theframe 22 is passed through the edging 26 and around the periphery of each of theside panels 20. The ends of theframe 22 are joined together such that theframe 22 forms a continuous loop. In the preferred embodiment, the frame ends are connected by inserting each end into a butt connector and crimping the connector. Finally, the unstitched portion of eachseam cover 28 is stitched toside 21 of eachweb 24 and over theends frame 22 from escaping theedgings 26. - From the expanded state, the
structure 10 may be folded into a collapsed state for storage and transportation. FIGS. 31 to 36 show various steps for collapsing thestructure 10. Referring toFIG. 31 , the first step requires grasping opposite sides of thestructure 10 and biasing one toward the other until allside panels 20 are adjacent and overlay each other. The next step includes inserting thehandle members floor panel 50 in between any two of the adjacentoverlaying side panels 20 is shown inFIG. 32 . It is important to make sure that thestorage pouch 70 remains outside of thecollapsed side panels 20. In the preferred embodiment, the resulting partially collapsedstructure 10 is a stack of fourside panels 20.FIGS. 33 and 34 show the next step of rotating twoopposite corners structure 10 in opposite directions while biasing thecorners structure 10 will first twist and then will rotate to form three overlayingcircular loops 150 situated adjacently as shown inFIG. 35 . The final step, shown inFIG. 36 , is the insertion of thecollapsed structure 10 into thestorage pouch 70. - When the
collapsed structure 10 is removed from thestorage pouch 70, theframe members 22 will bias thestructure 10 into its fully expanded state. Again, the fully expanded state of the embodiment is that shown inFIG. 4 . - Referring now to
FIGS. 37-40 , the preferred embodiment of the collapsible structure is shown asreference numeral 100. Thestructure 100 includes fourside panels 20 and afloor panel 50. Theside panels 20 andfloor panel 50 are connected to one another to form thestructure 100 having an open top 16. Twoside panels 20 are connected to form apair 84 ofside panels 20. Twopair 84 ofside panels 20 are preferably used to form thestructure 100. The preferred embodiment in these views includes a single modifiedframe 22′ for eachpair 84 ofside panels 20. Eachside panel 20 further comprises aweb 24 and an edging 26. As in the previous embodiments, theweb 24 is a flexible foldable material, such as nylon cloth or nylon mesh, but any suitable material may be used. The material may be solid or perforated, as desired. Theframe 22′ is flexible, preferably formed from a sufficiently stiff yet resilient material such as spring steel wire or plastic, and similarly to the previously described embodiments, is contained within the channel or pocket 25 (seen in FIG. 55) formed by the edging 26. The edging 26 is a foldable, but stretch-resistant material capable of housing the modifiedframe 22′ within itspocket 25. The edging 26 has two ends, 27 and 29. Theframes 22′ are each formed in a “figure eight” configuration as will be discussed in more detail. As shown inFIG. 53 b, theframe 22′ has a rectangular cross-section, but a material with a different geometric cross-section may be used. For purposes of example only, an alternative cross-section, seen as circular, is shown inFIG. 54 b. -
FIGS. 41-43 illustrate another embodiment of the twoframe structure 100. In this embodiment, aseam cover 28 is stitched to eachweb 24 and over the open ends 27 and 29 of each edging 26, thereby protecting theframe 22′ from escaping the edging 26. Each seam cover 28 includes a flap or unstitched portion, and it is to be understood that it could be placed anywhere on any side of each of thewebs 24, depending on the insertion point of theframe 22′ defined by the open ends 27 and 29. -
FIGS. 44-49 illustrate the various stages in the manufacturing process of the two-frame structure 100 shown inFIGS. 37-40 . To form thefirst pair 84 ofcontiguous side panels 20, two integrally formed,contiguous webs 24 seen inFIG. 44 , are provided. Edgingmaterial 26 is then attached to theweb 24 perimeter and a portion of thecontiguous border 72, as shown inFIG. 45 . The edging 26 is folded in a channel-like fashion around the periphery of theweb 24 and stitched to theweb 24 withstitching 30. The folded and stitched edging 26 forms a pocket 25 (seen best inFIG. 55 ) around the periphery of theweb 24. Stitching of each edging 26 starts and ends at the open ends 27 and 29, preferably located at thecontiguous border 72. - The next steps of the manufacturing process of the present invention involve inserting the
frame 22′ in one of the open ends 27 or 29 of the edging 26 as shown inFIG. 47 . Theframe 22′ is passed through the edging 26 and around the periphery of each of theside panels 20. As theframe 20′ completes its circuit around thefirst side panel 20, it crosses over itself atopen end second panel 20. When theframe 22′ is completely inserted in thepocket 25 surrounding bothpanels 20, the ends of theframe 22′ are joined together at ahelical portion 68 such that theframe 22′ forms a continuous loop. In the preferred embodiment, the frame ends are connected by inserting each end into abutt connector 64 and crimping the connector 64 (see in particularFIG. 52 ). The steps shown inFIG. 44-49 are completed a second time to form asecond pair 84 ofcontiguous side panels 20. As illustrated in FIGS. 50 51 b, the first andsecond pair 84 ofcontiguous side panels 20 are positioned to form thestructure 100. Thefloor panel 50 is attached to thefloor side 34 ofpanels 20, as shown particularly inFIG. 50 , and the first andsecond pair 84 ofcontiguous side panels 20 are attached to one another along the edging 26 oflateral sides panels 20. As shown inFIG. 51 b, anoptional storage pouch 70 may be formed from a foldable material, such as nylon mesh, and stitched to thetop side 32 of one of thepanels 20. Thestorage pouch 70 is dimensioned to accommodate thestructure 100 in its collapsed state, as will be described. - As will be observed in
FIGS. 52-54 b, theframe 22′ includes ahelical portion helical portion 68 has a relatively flat cross section whereas theportion 68′ may be formed with a circular cross section. Thehelical portions frame 22′ which allows facile folding and unfolding of eachindividual pair 84 ofpanels 20, as will be later described. -
FIGS. 56-60 b illustrate an alternative manufacturing process of the two-frame structure 100. Seen particularly inFIG. 56 , four integrally formed,contiguous webs 24 are provided. As shown inFIG. 57 , edgingmaterial 26 is then attached to theweb 24 perimeter and a portion of thecontiguous border 72, leavinginsertion areas 74 defined byopen ends web 24 and stitched to theweb 24 withstitching 30. As seen inFIG. 55 , the folded and stitched edging 26 forms apocket 25. Stitching of each edging 26 starts and ends at open ends 27 and 29. - The next step in the alternative manufacturing process involves inserting a
frame 22′ at eachinsertion area 74, in anopen end FIG. 46 , eachframe 20′ of the embodiment shown inFIG. 58 completes its circuit around apanel 20, crosses over itself atinsertion area 74, and enters asecond panel 20 inopen end frame 22′ is completely inserted in thepocket 25 surrounding twoadjacent panels 20, the ends of theframe 22′ are joined together to form a continues loop. Acrimped butt connector 64 retains the ends. The alternative method of manufacture is completed as seen inFIGS. 59 and 60 in a manner similar to that described with reference toFIGS. 50 and 51 . The method may optionally include astorage pouch 70, as seen inFIG. 60 b. - As discussed in reference to the primarily described embodiments shown in
FIGS. 1-30 , the twoframe structure 100 ofFIGS. 37-61 may, from the expanded state, be folded into a collapsed state for storage and transportation. FIGS. 31 to 36 show various steps for collapsing thestructure 10, and the twoframe structure 100 is similarly collapsed, as shown inFIGS. 62-67 . Referring toFIG. 62 , the first step requires grasping opposite sides of thestructure 100 and biasing one toward the other until allside panels 20 are adjacent and overlay each other. The next step includes inserting thehandle members floor panel 50 in between any two of the adjacentoverlaying side panels 20 is shown inFIG. 63 . It is important to make sure that thestorage pouch 70, if provided, remains outside of the collapsed side panels 20 (as shown inFIG. 33 ). The resulting partially collapsedstructure 100 is a stack of fourside panels 20.FIGS. 64 and 65 show the next step of rotating twoopposite corners structure 100 in opposite directions while biasing thecorners structure 100 will first twist and then will rotate to form three overlayingcircular loops 150 situated adjacently as shown inFIG. 66 . The final step, shown with reference to structure 10 inFIG. 36 , is the insertion of thecollapsed structure storage pouch 70, if provided. - When the
collapsed structure 100 is removed from thestorage pouch 70, theframe members 22 will bias thestructure 100 into its fully expanded state. - An alternative folding step may be seen in
FIG. 67 wherein the twoframe structure 100 may be finally secured in the collapsed state by way of an elasticflexible band 66. -
FIGS. 68-70 c, inclusive, illustrate a further embodiment of thecollapsible structure 10. Eachside panel 20 comprises aframe 22, aweb 24, and an edging 26. As in the previously mentioned embodiments, theframe 22 is flexible, preferably formed from a sufficiently stiff yet resilient material such as spring steel wire or plastic, and is contained within the channel orpocket 25 formed by the edging 26 (as seen inFIG. 6 b). The perimeter of theweb 24 is stitched to the edging 26 such that the edging 26 forms apocket 25 substantially about the periphery of theweb 24. At least one of thewebs 24 includes edging 26 having anon-continuous gapped portion 48. Thegap 48 defines an area wherein theframe 22 is exposed. As illustrated inFIGS. 70 a-70 c, ahandle 60 may be inserted in thegap 48 between edging ends 27 and 29. After insertion ingap 48, thehandle 60 is looped around theframe 22. As seen particularly inFIG. 70 c, thehandle 60 may be stitched at 78 for securement after insertion ingap 48. Alternatively, thehandle 60 may be affixed to itself or the frame member with adhesive or another securement means. Both handles 60 and 62 may be attached in this manner. - It is to be understood that although not specifically illustrated in the Figures, handles 60 and 62 may be secured by looping around the
frame 22 of any of the foregoing embodiments. -
FIGS. 71-77 , inclusive, illustrate a further embodiment of thecollapsible structure 200. Thestructure 200 preferably includes fourside panels 20 and afloor panel 50. Theside panels 20 andfloor panel 50 are connected to one another to form a substantially rectangular structure having an open top 16. - Referring to
FIGS. 71 and 72 it may be seen that eachside panel 20 comprises aframe 22 and a two-ply web 124. As in the previously mentioned embodiments, theframe 22 is flexible, preferably formed from a sufficiently stiff, yet resilient, material such as spring steel wire or plastic. In the embodiment shown inFIGS. 71-77 , and as seen particularly inFIG. 72 , theframe 22 is captured between the twolayers ply web 124. Theframe 22 forms a loop.
