Definitions

  • the present invention is related to collapsible toy structures such as tents and playhouses.
  • Collapsible structures that are used for playhouses are well-known in the art. They are typically collapsible into a small volume but can be easily popped up by various means, including the use of extendable frames and inflatable tubes.
  • U.S. Pat. No. 6,305,396 described a collapsible structure that is provided with a plurality of foldable frame members each having a folded and an unfolded orientation. A fabric material is provided for covering a portion of each frame member to form a side panel therefrom.
  • the structure may be folded and stored by folding the side panels and their corresponding frame members on top of each other about the hinge portions to have the side panels and frame members overlying each other.
  • the overlying side panels and frame members are then collapsed by twisting and folding to form a plurality of concentric frame members to substantially reduce the size of the structure.
  • the present invention provides a foldable enclosure structure containing a fabric cover defining a desired shape when expanded to an expanded position; a first supporting frame attached to the cover; and a second supporting frame provided within the cover and rotatably coupled to the first frame such that the second frame is movable between a collapsed position and an expanded position.
  • the second frame is superposed over the first frame in the collapsed position for ease of storage, but is rotated axially to intersect with the first frame in the expanded position to prop up the cover to the desired shape.
  • fixing means are provided for fixedly attaching the second frame to the first frame in the expanded position.
  • the shape of the two frames assume the same shape as the cross-sectional shape of the cover along the points to which they attach such that they are effectively prop up the cover in the expanded position.
  • first and second frames are both fixedly sewn onto the cover.
  • the frames may be sewn either onto the inner or outer sides of the cover.
  • the intersections between the first and second frames are left unsewn, such that the two frames can rotate axially relative to each other.
  • the first and second frames are each foldable from an open position to a folded position, the folded position achievable by twisting and folding the frames into at least two concentric circles. Since the two frames are superimposed onto each other in the collapsed position, it is most convenient for the user to twist and fold the two frames together simultaneously. This would reduce the total area of the collapsed structure to a minimum.
  • the first and second frames are each in the general shape of a loop and containing a first and second central vertical axis respectively.
  • the first and second frames are coupled together such that the first and second central vertical axes coincide with each other, and the second frame rotatable therealong.
  • the two loops may be coupled theretogether by an elastic band provided at the top intersection between the frames.
  • the fixing means is a set of Velcro tapes that allow the two frames to be fixedly attached together after the second frame has been rotated to the expanded position.
  • the fixing means is a bottom pad for mounting onto the bottom of the enclosure.
  • This bottom pad has a bottom frame shaped to match the shape of the bottom of the desired shape for abutment of the first and second frame in the expanded position.
  • At least one reinforcement frame may further be attachable along the girth of the first and second frames in the expanded position to prop up the cover to the desired shape.
  • This reinforcement frame is preferably attached to the first and second frames after they are arranged into the expanded position.
  • the cover defines a complete enclosure with a top portion, a bottom portion and side portions for sheltering at least one person therein, the cover further provided with at least one opening for the person to access therethrough.
  • the first and second frames are each in the general shape of a loop with a first and second central horizontal axis respectively.
  • the first and second frames are coupled together such that the first and second central horizontal axes coincide with each other, and the second frame rotatable therealong.
  • This embodiment is suitable for shapes such as aeroplanes and airships.
  • the fixing means is at least one loop attachable to the first and second frames along the vertical girth for abutment in the expanded position.
  • a method of supporting a fabric enclose comprising providing a plurality of rigid or semi-rigid loops having a shape of a second of the enclosure and defining a central axis therein; fixedly attaching one of the loop to a cross-section of the enclosure; and coupling the other loop or loops to the attached loop at a position wherein the loop or loops are rotatable along the central axis relative to the attached loop.
  • the loops in pre-determined relative position are abutted into position using a reinforcement frame.
  • FIG. 1A is a drawing of an exploded view of the supporting structures according to one embodiment of the present invention.
  • the fabric cover is not shown for ease of understanding.
  • FIG. 1B shows the assembled supporting structures according to the same embodiment as FIG. 1A. The fabric cover is not shown.
  • FIG. 1C shows the perspective view of the fully expanded cover of the enclosure structure according to the same embodiment as FIG. 1A with windows and openings that can be provided on the cover.
  • FIG. 1D shows the step of the folding process for a frame into three concentric loops.
  • FIG. 2A shows a second embodiment according to the present invention in which a first, second and third frames are rotatable along a horizontal axis in an expanded position.
  • FIG. 2B shows an additional reinforcement loop provided within the structure shown in FIG. 2A.
  • FIG. 2C and 2D shows a second and third reinforcement loop provided respectively within the structure shown in FIG. 2B.
  • FIG. 3 shows a third embodiment of the present invention in which additional structures are provided.
  • the term “fabric” is simply used to describe a material that has the collapsible and foldable characteristics of a fabric, and is not meant to limit the instant invention to any particular type of material.
  • the cover may be made of, among other things, nylon, cotton, leather, PVC and other natural, synthetic or blended material.
  • the term “loop” is defined loosely as any rigid or semi-rigid frame that forms a complete piece without any break in the frame.
  • the “loop” may be of any shape, such as circular, triangular, quadrilateral, polylateral, mushroom, or any other regular or irregular shape.
  • a “semi-rigid” frame has the characteristic of maintaining a defined shape when it is expanded into the fully open position, but can also be folded, or twisted into concentric circles, or otherwise collapsible by other ways.
  • the first embodiment exemplifying the present invention shows two identical frames 22 and 24 that have a mushroom-like shape in the fully open position.
  • a fabric enclosure assuming the shape of a mushroom with a dome-shaped top 23 a and a short, thick stem at the bottom 23 b (see FIG. 1C).
  • the bottom portion of the stem is also shown to have a girth that spreads wider than the top portion of the stem.
  • FIG. 1C shows the fabric enclosure or cover, and the relative position of the same cover is only shown as dotted lines in FIG. 1A.
  • the two frames in the open position assumes a shape that is the same as the cross-sectional shape of the cover (i.e.
  • first frame 22 is sewn and fixed onto the appropriate position along the cover.
  • the first frame is sewn on the inside of the cover.
  • the two frames are provided in the upright position, each with a central vertical axis defined therein (in FIG. 1A, the two frames are positioned such that their central axes coincide along line 26 ).
  • the second frame is also be fixedly sewn onto the inside of the cover, except that the points of intersection 28 and 30 with the first frame are not sewn to the cover, such that the two frames may rotate axially relative to each other as shown by arrow 40 .
  • first and second frames may be sewn either on the outside or the inside of the cover, and are considered “rotatably coupled” with the cover itself acting as the coupling means.
  • the frames are arranged such that they are axially aligned along the vertical axis and, when the frames are in the expanded position, intersect at a 90 degree angle.
  • three optional reinforcement loops 32 , 34 and 36 of varying sizes, and a square pad 38 with a semi-rigid frame is also provided.
  • Pad 38 assumes the same shape as defined by the bottom of the two frames, and once it is inserted into the enclosure as shown in FIG. 1B, the two frames would be secured at a 90 degree angle.
  • the three reinforcement loops can then be attached along various heights of the girth of the top portion of the mushroom structure, for example by velcro tapes provided at the appropriate position.
  • the cover 25 as shown in FIG. 1C also illustrates how windows 25 a and openings 25 b may be provided.
  • FIG. 2A to 2 C another embodiment of the present invention is shown in the form of a generally olive-shaped space ship.
  • the fabric cover is not shown in order to review the supporting structures therein. It is understood that openings may be provided in the enclosure for a user such as a child to enter the space ship and reside within the confines of the frames.
  • Frame 42 is fixedly sewn onto the inner side of the cover, and frames 44 and 46 are rotatably coupled therein using an elastic band attached to the cover at the two side ends 48 and 50 of the spaceship such that frames 44 and 46 are rotatable along a horizontal as 52 that also coincides with their respective longitudinal axis of symmetry. In the expanded position as shown, the three frames intersect each other at an angle of 60 degrees.
  • FIG. 2B shows one large reinforcement loop 54 provided at one end of the olive-shaped structure and aligned perpendicularly to the axis 52 .
  • the vertical alignment of the reinforcement loop relative to the horizontal axis of rotation is referred to as attachment of the reinforcement loop to the vertical girth of the frames.
  • Fixing means such as Velcro tapes are provided at the relevant position of the inner side of the enclosure for the secure position thereof.
  • the reinforcement loop 54 assumes a curved shape 54 a along 3 ⁇ 4 of sides, but contains on flat side 54 b which is preferably facing the floor to stabilize the entire spaceship structure.
  • FIGS. 2C and 2D shows two further reinforcement loops 56 and 58 provided at the mid-section and right-end section of the space ship. Again, Velcro tapes are provided along the designated positions of the inner side of the cover for fixed attachment thereto. Again, the bottom side of these two reinforcement loops are flat to provide stability to the whole structure.
  • the three reinforcement loops may again be detached and the three frames 42 , 44 and 46 be rotated to superimpose on each other in the collapsed form. If the three frames are large, and made of a semi-rigid material, they can be further twisted and folded simultaneously each into two or three concentric circles for storage. The three frames will stay within the fabric of the cover, and they are attached or coupled to the inner side thereof, and therefore the entire structure would conveniently be stored. The three reinforcement frames may also be twisted and folded and put in the same small bag for storage.
  • FIG. 3 shows another embodiment in which the basic enclosure or cover is a cube 60 , supported by two square frames 62 and 64 .
  • One optional square reinforcement frames 66 and one optional abutment frame 68 are also provided at the top and bottom respectively of the enclosure, said fixed thereto by fixing means such as Velcro tapes.
  • An opening 70 is provided on the cover for a user to access the interior. Windows 70 a are also provided.
  • four additional conical/cylindrical structures 72 are provided at the four corners to give the structure the appearance of a castle. The structures 72 are simply attached onto the expanded cover using velcro tape as illustrated in the shaped area 74 . For ease of illustration, only one of the four areas is shaped so as not to obscure the other structures.
  • the present invention may clearly be practised with more than two loops.
  • this may be a substitution for the reinforcement frames in the larger enclosures.
  • the loops may be, for example, spread evenly at 60 degree angles into three evenly distributed frames.
  • the bottom pad if desired, may be a hexagon.
  • the coupling means as described in the first example actually uses the cover therefor, with the two frames fixed thereto except at the points of intersection, while elastic band is described as the coupling means in the second example.
  • elastic band is described as the coupling means in the second example.
  • strings and mechanical joints may also be used.
