Collapsible play box
A child's play box includes a pliable base piece and four semi- rigid, planar sidewalls. The base piece has four edges, and each sidewall is joined to the base piece by a folding joint that permits the sidewall to pivot with respect to the base piece. Furthermore, each sidewall is joined to adjacent sidewalls by folding joints that permit the adjacent sidewalls to pivot with respect to each other. The folding joints collectively allow the play box to be manipulated between an open configuration in which the sidewalls extend perpendicularly from the base piece to define an internal cavity and a closed configuration in which all of the sidewalls are arranged in a stack.
This invention relates generally to play equipment for children and more particularly to a play box capable of holding various play media.
Parents of young children have long sought ways to keep their children amused and entertained. Playpens and similar enclosures are widely used to allow a child to play with minimal supervision. However, most currently available playpens are relatively large and inconvenient to store when not in use. While collapsible playpens are available, they still tend to be bulky and difficult to set up and collapse, which limits their portability. Moreover, playpens are confining by nature and do not provide much stimulation to the child.
Other items available for child play include sand boxes and wading pools. While these devices provide a medium (i.e., sand or water) for children to play in, they are generally limited to outdoor use and not typically used in a variety of locations.
Accordingly, there is a need for a versatile, portable play device that allows children to explore many play media.
SUMMARY OF THE INVENTIONThe above-mentioned need is met by the present invention, which provides a child's play box having a pliable base piece and four semi-rigid, planar sidewalls. The base piece has four edges, and each sidewall is joined to a respective edge of the base piece by a folding joint that permits the sidewall to pivot with respect to the base piece. Furthermore, each sidewall is joined to adjacent sidewalls by folding joints that permit the adjacent sidewalls to pivot with respect to each other. The folding joints collectively allow the play box to be manipulated between an open configuration in which the sidewalls extend perpendicularly from the base piece to define an internal cavity and a closed configuration in which all of the sidewalls are arranged in a stack.
The present invention and its advantages over the prior art will be more readily understood upon reading the following detailed description and the appended claims with reference to the accompanying drawings.
DESCRIPTION OF THE DRAWINGSThe subject matter that is regarded as the invention is particularly pointed out and distinctly claimed in the concluding part of the specification. The invention, however, may be best understood by reference to the following description taken in conjunction with the accompanying drawing figures in which:
Referring to the drawings wherein identical reference numerals denote the same elements throughout the various views,
Each one of the sidewalls 14, 16, 18 and 20 is joined along one edge to a respective edge of the base piece 12 by a corresponding folding joint that permits the sidewall to pivot with respect to the base piece 12. In addition, each sidewall 14, 16, 18 and 20 is joined at both ends to corresponding ends of two adjacent sidewalls by folding joints that permit adjacent sidewalls to pivot with respect to each other, thereby defining four corners A, B, C and D. All of the folding joints (i.e., those between the sidewalls 14, 16, 18 and 20 and the base piece 12 and those between adjacent sidewalls) are design to provide a full range of pivoting motion between the connected elements. For example, the folding joint between the base piece 12 and the first sidewall 14 permits the first sidewall 14 to pivot through a substantially 360 degree angle relative to the base piece 12. The folding joints act collectively to allow the play box 10 to be manipulated between an open configuration (shown in
The play box 10 includes a set of suction cups 22 attached to the underside of the base piece 12 for anchoring the play box 10 to a support surface. Alternative anchoring means, including but not limited to hooks, straps, adhesive pads and magnets, could be used instead of the suction cups. The play box 10 can also be provided with a closeable drain 24 formed in one of the sidewalls 14, 16, 18 and 20, preferably near the base piece 12. Opening the drain 24 would allow play material to drain from the play box 10. The drain 24 could be alternatively located in the base piece 12.
The base piece 12 is preferably a pliable sheet of material that is capable of being freely and repeatedly bent or folded without breaking. On the other hand, the sidewalls 14, 16, 18 and 20 are semi-rigid pieces. As used herein, “semi-rigid” means that the sidewalls 14, 16, 18 and 20 generally will not bend under their own weight or light forces but are sufficiently flexible so as to bend when a moderate force is applied. Both the base piece 12 and the sidewalls 14, 16, 18 and 20 are made from waterproof and durable materials. For example, the base piece 12 can be made of a sheet of an acrylic-coated fabric, vinyl or another suitable plastic material. As shown in
As mentioned above, the play box 10 is collapsible and can be manipulated between an open configuration for use and a closed configuration for storage when not in use. When in the open configuration, the play box 10 can be converted to the closed configuration by pushing one of the four corners, for example corner B, to its opposing corner, corner D in this example. As corner B is pushed towards corner D with sufficient force, the sidewalls 14, 16, 18 and 20 will flex or bow inwardly as shown in
Next, corners A and C are pushed together so that folding joints of corners B and D fold inward. This results in the play box 10 assuming its closed configuration in which all of the sidewalls 14, 16, 18 and 20 are arranged in a stack with the first and second sidewalls 14 and 16 being positioned between the third and fourth sidewalls 18 and 20, as shown in
While the sidewalls 14, 16, 18 and 20 can have equal lengths, as mentioned above, it is noted that providing two of the sidewalls with a slightly shorter length than the other two sidewalls facilitates the folding process. By way of example, the first and second sidewalls 14 and 16 could be 19% inches long and the third and fourth sidewalls 18 and 20 could be 20 inches long.
While specific embodiments of the present invention have been described, it will be apparent to those skilled in the art that various modifications thereto can be made without departing from the spirit and scope of the invention as defined in the appended claims.
Claims
