Description

FIELD

This disclosure relates to a collapsible furniture support structure. More particularly, this disclosure relates to a collapsible brace members having a handle for manipulating the brace members between an extended position and a collapsed position.

BACKGROUND

Conventional folding leg assemblies for furniture support structures such as tables and benches often include brace members. One end of the brace member is typically connected to the bottom of the support structure while the opposite end of the brace member is connected to one or more legs. When the brace member is in an extended position, the one or more legs connected to the brace member are in a use position (i.e., the legs are supporting the support structure at a particular height above the ground). When the brace members are in a collapsed position, the legs are in a folded position typically disposed along the bottom surface of the support structure for storing and/or transporting the support structure.
One problem associated with conventional brace members is that it is often difficult for a user to manipulate the brace members between the extended position and the collapsed position. Another problem is that the support structure, particularly larger/longer support structures, may be difficult to carry in the folded position.
What is needed therefore is a folding leg assembly having brace members that are easily manipulated between the extended position and the collapsed position as well as a system for assisting in carrying the support structure when the brace members are in the collapsed position.

Referring to FIGS. 1 - 8, a furniture support structure 10 in accordance with one exemplary embodiment of the present disclosure includes a planar top surface 12, a bottom surface 14 opposite the top surface 12, a first end 16, a second end 18 opposite the first end 16, a first side 20, and a second side 22 opposite the first side 20. The top surface 12 is preferably rectangular shaped as shown, but may also be square, oval, circular, or irregular shaped within the spirit of the present disclosure. The top surface 12 is preferably formed from blow-molded plastic, but other materials can also be applicable. Secured to the bottom surface 14 are a plurality of folding leg assemblies 24. In preferred embodiments, the bottom surface 14 includes frame members 15, and the folding leg assemblies 24 are attached to the frame members 15 as described below.
The furniture support structure 10 of the present disclosure, and more particularly the folding leg assemblies 24 for the support structure 10, is believed to be best utilized with respect to furniture support structures having an elongated top surface 12. Even more specifically, the folding leg assemblies 24 of the present disclosure are believed to be particularly suited for structures 10 having an elongated top surface 12 that are intended to be disposed relatively low to the ground, such as the bench as shown. However, the present disclosure can also be utilized for many different structures such as tables, chairs, stools, television trays, etc. having folding leg assemblies and other folding mechanisms. Thus, while the present disclosure is shown and described herein with respect to a bench 10, it should be understood that the disclosure could also be utilized with respect to other surfaces that are supported by folding leg assemblies and other folding mechanisms.
As shown best in FIG. 2, each folding leg assembly includes a first leg 30 and a second leg 40. Each leg is attached to an axle 32, 42 that is rotatably secured to a frame member 15 extending along the length of the bottom surface 14. As shown, each leg may be secured to a separate axle 32, 42. However, according to alternate embodiments, first leg 30 and second leg 40 may be secured to a single axle extending along the width of the bottom surface 14. As shown, a support member or pedestal 60 is preferably provided for securing the first leg 30 to the second leg 40 and providing additional support when the support structure 10 is in a use position.
Secured to the first leg 30 is a first brace member 34 and secured to the second leg 40 is a second brace member 44. Each brace member 34, 44 includes an upper portion 36, 46 and a lower portion 38, 48. The upper portion 36, 46 of each brace member 34, 44 is secured to their respective leg, and the lower portions 38, 48 are secured to the frame members 15 extending along the length of the bottom surface 14. Each brace member 34, 44 further includes a pivot member 39, 49 for connecting the upper portion 36, 46 to the lower portion 38, 48 such that each brace member 34, 44 is movable between an extended position and a collapsed position. Axles 32, 42 allow the legs 30, 40 to pivot when the brace members 34, 44 are moved between the extended position and the collapsed position so that the legs are movable between a use position (FIGS. 1 - 5) and a folded position (FIGS. 6 - 8).
A handle 50 is preferably disposed between the first brace member 34 and the second brace member 44 for manipulating the pivot members 39, 49 of the first and second brace members. As a result of the handle 50 connecting the pivot members 39, 49, both brace members 34 and 44 are operable to be manipulated between the extended position and the collapsed position together (i.e., the pivot members 39, 49 are concurrently manipulated using handle 50). In preferred embodiments, the handle 50 includes a cross member 52 having a first end secured to the first brace member 34 and a second end secured to the second brace member 44 and a handle portion 54 extending from the cross member 52 to make it easy for a user to grasp handle 50 using handle portion 54. In preferred embodiments, cross member 52 is welded on opposing ends to the brace members 34 and 44.
Referring to FIGS. 1 - 5, the first and second legs 30, 40 of each folding leg assembly 24 are in a use position when the first and second brace members 34, 44 are in the extended position. According to preferred embodiments, the handle portion 54 is dimensioned and configured to extend in the opposite direction of the first and second legs 30 and 40 (i.e., extend away from the legs) for easier access to the handle portion while the support structure 10 is in the use position. Referring to FIGS. 6 - 8, the first and second legs 30, 40 are in a folded position when the first and second brace members 34, 44 are in the collapsed position. When the first and second legs 30, 40 are in the folded position, the handle portion 54 is preferably dimensioned and configured to extend substantially perpendicular to the bottom surface 14 to assist in carrying the support structure 10.
Referring to FIGS. 2 and 5, each brace member 34, 44 preferably includes a spring 56 or similar extendable mechanism attached to the upper portions 36, 46 and lower portions 38, 48 of each of the first and second brace members 34, 44 for biasing the respective brace member to the extended position. In preferred embodiments, the upper portions 36, 46 and lower portions 38, 48 form recesses 31, 41 across the pivot members 39, 49, and the springs 56 or similar extendable mechanisms are disposed within the recesses 31, 41.
Referring to FIGS. 5 - 7, the support structure 10 preferably includes one or more clips 58 secured adjacent the bottom surface 14 for receiving the first and second legs 30, 40 in the folded position. As shown, clips 58 are preferably positioned to receive the first and second legs 30, 40 via pedestal 60. Thus, according to this embodiment, one clip 58 may be used to secure both the first and second legs 30, 40 of a folding leg assembly 24 adjacent to the bottom surface 14 of the structure 10 in the folded position by being positioned to receive the pedestal 60 (or other type of support member) connecting the first and second legs 30, 40. Additional clips 58 may be used to assist in securing the legs 30, 40 adjacent to the bottom surface 14 of the support structure 10.
