For the purpose of understanding particular embodiments, reference will now be made to the drawings.
As shown in
The collapsible support structure 100 further comprises a bottom portion 190. When the collapsible support structure 100 is in an unfolded position, the bottom portion 190 extends generally horizontally and can be elevated from the ground surface. As such, the bottom portion can provide vertical support. For example, depending on the application for the collapsible support structure, bottom portion 190 can be configured to support any of a small or large pet, a child, an adult, or any physical object.
The bottom portion 190 can comprise a solid fabric. Alternatively, the bottom portion 190 can comprise any other material or fabric, including mesh materials, polyester, and ballistic nylon. Preferably, the bottom portion 190 comprises a flexible material that is capable of being folded. In preferred embodiments, the bottom portion 190 comprises a material or fabric that is machine-washable. The material or fabric of the bottom portion 190 can be UV protected and mildew resistant. In addition, the bottom portion 190 can comprise webbing around its perimeter in an “X” shape or any other combination of patterns.
The top portion 110 can be configured as a canopy to provide shade to the interior of the collapsible support structure. As shown, the top portion 110 extends generally horizontally and can be substantially parallel to a ground surface. In other embodiments, the top portion can be provided at an angle to a ground surface.
The top portion 110 comprises a solid fabric. Alternatively, the top portion 110 can comprise any other material or fabric, including mesh materials, polyester, and ballistic nylon. In preferred embodiments, the top portion 110 comprises a material or fabric that is machine-washable. The material or fabric of the top portion 110 can be UV protected and mildew resistant.
The top portion 110 can be attached to the structure by several attachment pieces, such as attachment piece 112. In particular, attachment piece 112 can be any type of fastener, including a thumbscrew-type fastener and a coin-slot head-type fastener. Preferably, the attachment pieces connect the top portion to the tops of the plurality of poles. For example, attachment piece 112 connects the top portion 110 with the top of pole 120A. Removal of the attachment pieces can provide for easy removal of the top portion 110.
In alternative embodiments, the top portion is not connected with attachment pieces. Instead, the top portion can rest on top of the plurality of poles. By resting on the plurality of poles, the top portion can be easily removed for washing.
In addition, the material or fabric of top portion 110 can be supported by the plurality of poles 120A, 120B, 120C, and 120D but not otherwise supported by another structural member. In alternative embodiments, additional structural members can be used to provide support for the top portion.
In other alternative embodiments, the collapsible support structure does not comprise a top portion. If no top or side portions are provided, the plurality of poles need not necessarily extend above the bottom portion.
As shown in
The side portions 160 can further include an opening portion 170 that can selectively provide access to the interior volume or be closed such that no immediate access is provided. For example, the opening portion 170 can act as a door. Various mechanisms can be provided to allow the opening portion 170 to open and close. For example, as shown in
The side portions 160 can be secured to the collapsible support structure in a variety of ways. For example, in some embodiments, the side portions 160 can be fitted about the plurality of poles such that the force of friction is sufficient to keep the side portions 160 in a raised position. Alternatively, various attachment mechanisms may be provided to connect the side portions to the plurality of poles, including coin fasteners, coin-slot head-type fasteners, screws, plug and socket, hook and loop connections, as well as any other means of connection.
In alternative embodiments, the opening portion can be provided in the top portion. For example, in some embodiments the collapsible support structure is configured as an instant storage container. Providing the opening portion in the top portion can facilitate vertical access to the storage container. Alternatively, multiple opening portions may be provided. In addition, a single opening can extend to more than one surface of the support structure.
The opening portion can be made of any material or fabric. The opening portion can be made of the same material or fabric as the side portions or top portion, or the opening portion can be made of a different material or fabric. In the embodiment illustrated in
The dimensions in
Support member 250 can connect to the pole 220 through the slider 230. A person of ordinary skill will appreciate the variety of mechanisms that allow the support member 250 to connect to the slider 230. For example, any mechanism that connects the support member 250 to the slider 230 and provides for the support member 250 to be rotatable while transitioning from a folded to an unfolded position can be used.
In addition, support member 252 can connect to the pole 220 through the bottom pole support 240. Alternatively, support member 252 can connect directly to the pole 220. Support member 250 can be rotatably connected to support member 252 to form a pivot 254. The support members 250 and 252 can be movable about the pivot 254 to facilitate transition between a folded position in which the pole 220 is spaced substantially close to the other poles and an unfolded position in which the pole 220 is spaced apart from the other poles.
The slider 230 can be attached to the pole 220 and can comprise a hollow portion to facilitate movement of the slider along the pole 220. The terms “slider” and “slidable connector” are used interchangeably throughout and have the same meaning. A fastener 232 can be used to hold the slider together. The sliders can provide added vertical support to the bottom portion 290. In some embodiments, the fastener 232 can facilitate holding the slider 230 in place along the pole 220.
The “X”-member structure described above with respect to a front facing side of the collapsible support structure 200 can be repeated on each of the other sides of the collapsible support structure. For example, the collapsible support structure 200 comprises four poles, eight support members, four pivots, four sliders, and four bottom pole supports.
The bottom pole supports, including bottom pole support 240, can serve as feet that help to anchor the collapsible support structure 200. The bottom pole supports also may comprise spikes, such as those that may be used for a tent, to anchor the collapsible support structure to the ground in an outdoor location. The bottom pole supports may comprise a rough texture to provide added traction between the bottom pole supports and the ground.
A primary objective of the collapsible support structure 200 is to facilitate quick transition from a folded position to an unfolded position. In a folded position, the poles can be spaced substantially close to the other poles, the sliders can be placed in a vertically raised position along the poles, and the support members can be aligned or nearly aligned with each other as well as the poles. As such, a cross-sectional footprint of the collapsible support structure 200 can be at a minimum when in a folded position. In an unfolded position, the poles can be spaced relatively farther apart, the sliders can be placed in a vertically lowered position along the poles, and the support members are not aligned or nearly aligned in the same direction as the poles. In an unfolded position, a cross-sectional footprint of the collapsible support structure 200 can be at a maximum.
The extent to which the collapsible support structure 200 can unfold, and the extent to which the sliders can slide down the poles, can be limited by the size of the bottom portion 290. For example, when the collapsible support structure is unfolding, the support members connected to the sliders can push outwardly on the poles as the structure expands. As the sliders move down the poles, the support members can push the poles outwards. The bottom portion 290, which generally comprises a flexible material, does not initially resist this expansion. However, the bottom portion 290 is of a limited size. As the structure continues to unfold and expand, at a certain point the bottom portion 290 will become taught and no longer able to expand. At that point, the bottom portion 290 can pull inwards on the poles and balance the outward pressure from the support members and sliders. At that point, the support members can no longer expand outwards, and the sliders can no longer continue to move vertically down the poles. At that point, the collapsible support structure is in an unfolded position. The bottom portion 290 can be substantially horizontal and raised above a ground surface. Alternatively, the bottom portion may be adjacent to the ground. The sliders can provide added vertical support to the bottom portion 290 to maintain it in a raised position above the ground. For example, sufficient support can be provided to the bottom portion 290 to support any of a small or large pet, a child, an adult, or any physical object. In the event the bottom portion is removed, the sliders generally can continue to move down the poles until they contact the bottom pole supports.
The bottom portion can be connected to the sliders by way of an attachment piece. For example, the attachment piece can be any means of providing a connection between the bottom portion and the sliders, including a screw, a plug and socket, and a hook and loop mechanism. By connecting the bottom portion and the sliders, an attachment piece facilitates automatic pulling of the bottom portion into place as the collapsible support structure is expanded from a folded position to an unfolded position. In alternative embodiments, and as illustrated in
The “X”-members such as described with respect to
Support members 350, 352 can be movable about center pivot 354. Similarly, support members 351, 353 can be movable about center pivot 355. Support members 350, 353 can be movable about end pivot 356. Similarly, support members 351, 352 can be movable about end pivot 358.

The dimensions in
As shown in
The top portion 510 can be provided with a downward sloping angle. For example, the poles 520B, 520C can be comparatively taller than the poles 520A, 520D. As such, the top portion 510 can form a downward sloping angle as it extends from atop poles 520B, 520C down to poles 520A, 520D. Thus, liquid such as rain water will run off of the top portion and not accumulate.
In addition, the top portion 510 can have varying degrees of overhang on different sides. For example, on the taller side, the top portion 510 can have an overhang h1, and on the shorter side, the top portion 510 can have an overhang h2. As shown in
The dimensions in
Connecting screws 934A, 934B, 934C, and 934D can connect the bottom portion to sliders 930A, 930B, 930C, and 930D (not shown). By connecting the bottom portion and the sliders, the connecting screws 934A, 934B, 934C, and 934D facilitate pulling the bottom portion into place as the collapsible support structure is expanded from a folded position to an unfolded position. Alternatively, other means of attaching the bottom portion to the sliders may be used. For example, plug and socket, hoop and loop, and other means of connection may be used. In other alternative embodiments, no attachment mechanism of the bottom portion to the sliders is provided. Instead, the bottom portion can comprise holes for each pole so that the bottom portion may slide down the poles.
The support members can be movable to facilitate transition between a folded position in which the poles 1020A, 1020B, and 1020C are spaced substantially closer to each other and an unfolded position in which the poles 1020A, 1020B, and 1020C are spaced further apart from the other poles.
The sliders 1030A, 1030B, and 1030C can be slidably attached to the poles 1020A, 1020B, and 1020C. When the collapsible support structure is in a folded position, the sliders 1030A, 1030B, and 1030C can be positioned relatively closer to the top portion 1010 than when the collapsible support structure is in an unfolded position.
Additionally features found in other embodiments will now be described. Several features can be added to improve mobility of the collapsible support structure. For example, many embodiments can be combined with a carry case configured to transport a collapsible support structure when the structure is in a folded position. For example, a backpack can be used to transport the collapsible support structure.
In addition, in some embodiments, the collapsible support structure further can comprise one or more wheels that provide mobility to the collapsible support structure. For example,
Also, the collapsible support structure further can comprise a telescoping or hinged handle to aid the mobility of the collapsible support structure. The collapsible support structure can also be configured for transport within a carry case. For example, the collapsible support structure can also be configured for transport within a back pack.
In various embodiments, the collapsible support structure can be configured for a variety of purposes. In a preferred embodiment, the collapsible support structure can be configured as an enclosure for pets, such as an instant kennel. In instant kennel embodiments, the bottom portion can function as a dog bed. By being elevated, the dog bed keeps a dog cleaner and away from potentially wet grass, cold snow, hard cement, and ground insects. A breathable fabric may be provided for the dog bed to keep a dog more comfortable. In addition, the top portion can function as a canopy to provide shade to a pet. The top portion can provide sun and rain protection to a pet as the pet relaxes outdoors, helping keep the pet more comfortable. The instant kennel can include side portions comprising mesh materials and solid fabrics. In addition, the instant kennel can include a clear window as an opening portion. A zipper can be provided to open and close the window.
As the bottom portion can be elevated, cool air can be circulated underneath the bottom portion for added comfort. For example, circulation of cool air may be desirable on a warm day. In addition, warm air can be circulated underneath the bottom portion for added comfort. For example, circulation of warm air may be desirable on a cold day. In addition, circulation of air can help keep the material of the bottom portion dryer and cleaner.
In some embodiments, the bottom portion can offer a hammock-like effect for added comfort.
In another embodiment, the collapsible support structure can be configured as an instant playhouse, playpen, or castle for children. The instant playhouse, playpen, or castle for children can optionally provide an open-access top in which a top portion cover is lacking. The instant playhouse, playpen, or castle can be configured to meet or exceed CPSC standards.
