Collapsible container
A collapsible container is formed from a unitary structure which is selectively movable between a folded compact storage position and an extended operating position without assembling or disassembling components of the container. A positive locking component is provided to selectively retain the container in its compact folded position. The container has a liquid impervious inner lining which is foldable and extendable together with the container.
The present invention is directed to a foldable container, and in particular a foldable container having a liquid impervious inner lining to permit the container to be used as a water bucket in its extended position. More particularly, the foldable container in accordance with the present invention is of particular use in confined spaces, such as on a boat or sailboat where space is extremely limited.
Typical collapsible containers known to the art are exemplified by U.S. Pat. Nos. 1,133,648; 1,533,636; 1,928,976; 2,019,636; 3,337,086; and 5,752,649.
It is the primary object of the present invention to provide an improved collapsible container which is selectively movable between an extended operating position and a folded compact position in which the container can be stored.
It is a further object of the present invention to provide a collapsible container formed from a unitary structure to avoid assembling or disassembling different components when the container is moved between its collapsed and extended positions.
It is yet a further object of the present invention to provide a collapsible container having a liquid impervious liner which is movable, together with the container, as the container is moved between its folded and extended positions.
Other objects and advantages of the collapsible container in accordance with the present invention will become apparent to those skilled in the art from the following description in conjunction with the accompanying drawings.
SUMMARY OF THE INVENTIONA collapsible container is formed from a unitary structure having upper and lower container sections. The container sections are movable relative to each other, at the selection of a user, between an extended operating position and a folded compact storage position. In a first embodiment of the invention, the upper and lower container sections are joined together by resilient elements cooperating with hinge means for pivoting the upper and lower sections between extended and folded positions of the container. In a second embodiment of the invention, the upper and lower container sections are joined by integrally defined deformable elements which permit the upper and lower container sections to be selectively moved relative to each other between an extended operating position and a folded compact storage position.
Locking means associated with the container are provided for selectively retaining the container in its compact storage position and/or its extended operating position.
The container may also include an inner surface or liner formed from a liquid impervious material so that the container, in its extended position, can be used as a water bucket. The inner surface of the container will preferably be formed from a pliable material so that it is movable, together with the container, between the folded and extended positions of the container.
The collapsible container in accordance with the present invention is advantageously formed from a unitary structure so as to eliminate the need to assemble or disassemble components as the container is moved between its extended operating position and its folded, compact, storage position.
BRIEF DESCRIPTION OF THE DRAWINGS
The collapsible container illustrated by
Although not shown in the drawings, a pair of handles can be mounted to the top of the container to permit the container to be carried when it is folded into its compact storage position, and also to be carried in its extended position with liquid contained therein.
To move the container from its folded position to its extended position, the steps recited above are reversed. The hooks 10 are disengaged from the U-bolts 14. The resilient forces exerted by the springs 24 and 36 bias the container into its extended position when the hooks are disengaged from the bolts and when the tension on the straps is reached. The container remains in its extended operating position until a downward force overcoming the resilient bias of the springs 34 and 36 is applied to the top surface of the container, and the hooks 10 are re-engaged with the U-bolts 14.
When the container is in its extended operating position, the hooks 10 are disengaged from their corresponding retaining means (i.e., the U-bolts 14). Therefore, if desired, the hooks 10 can be used to releasably attach other articles to the container when the container is in its extended operating position.
When the container is in its extended operating position as illustrated by
To move the container from its folded position into its extended position, the steps described above are reversed. Hook 78 is disengaged from loop 76, and side post 60 is pivoted 90 degrees into its upright position. Sleeve 70 is slid over the pivot 68 to maintain the side post 60 in its upright position. Loop 62, with the plastic ring 63 (
The preferred embodiments of the invention primarily show the container in a square configuration, for illustrative purposes. However, it is within the scope of the present invention to employ containers of any configuration, including but not limited to square, rectangular, circular, and oval shaped.
Although the preferred embodiments of the invention discussed herein employ a tension spring as the means for moving the container into its extended operating position, other means are also within the scope of the present invention. For example, a hoop formed from spring steel, or gas driven cylinder may also be employed to move the container from its folded storage position to its extending operating position, at the selection of the user.
The reinforcement structure inserted into the extended container is formed from four (4) vertical struts designated by reference numeral 80 received in each corner of the extended container. Each strut 80 has a top platform section designated by reference numeral 82, and a bottom platform section designated by reference numeral 84. The top and bottom platform sections 82 and 84 are generally triangular in configuration, and are adapted to be received in the corner sections of the top 12 of the container, and the corner sections of the bottom 8 of the container, respectively. Adjacent vertical struts 80 are coupled together by horizontal rods 86 which are received in suitable connector elements 88 located at the approximate midpoints of the respective vertical struts 80. Preferably, the length of the horizontal rods connecting adjacent vertical struts 80 is slightly greater than the distance between the respective vertical struts so that the rods apply a continuous outwardly directed force against the vertical struts to maintain the structural integrity of of the overall reinforcement structure. The reinforcement structure defined by the vertical struts 80 and the horizontal rods 86 is removably insertable, as a unit, into the container in its extended operating position to enhance the structural stability of the container in its extended position. The reinforcement structure is removably received within the extended container, and is held in its reinforcing position by the upper and lower supporting platforms 82 and 84 of the vertical struts which are received within the top and bottom corners of the extended container so that the vertical struts advantageously reinforce the extended container at its corners.
Other modifications of the collapsible container disclosed and illustrated herein within the scope of the invention will be apparent to those skilled in the art. Therefore, the discussion and illustration of the preferred embodiments of the invention herein are intended to be illustrative only, and not restrictive of the scope of the invention, that scope being defined by the following claims and all equivalents thereto.
