BACKGROUND
1. Field of the Invention
This invention relates to work benches, and more particularly relates to a folding work bench movable between a folded configuration or partially folded configuration for convenient space-saving storage, and an unfolded configuration to provide a working surface and work space with ready access to a user's tools.
2. General Background and State of the Art
Many home owners have limited work shop or garage space for home repair projects and home construction projects. Typical home work shop work benches are permanent structures occupying a constant amount of space whether in use or not, and having places for storage of tools for ready access for use at the work bench. In such crowded work shop or garage spaces, it would be desirable to store the work bench and tools in a smaller space when not in use. Hooks of various sorts are often provided for hanging tools for ready access, but such tools are also typically not securable against theft when the work bench area is not in use, and it would be desirable to provide a way of securing such a work bench collection of tools against theft when the work bench area is not in use. The present invention satisfies these and other needs.
SUMMARY OF THE INVENTION
Briefly, and in general terms, the invention provides for a folding work bench that folds compactly for storage, such as in a storage box in a folded configuration or against a wall in a partially folded configuration, when not in use. The folding work bench occupies a minimal work space, allowing a work shop area in garage or basement to be utilized for other purposes as well. The folding work bench has a durable work table with a work surface, a top storage shelf, a back board member for hanging tools, and a locking mechanism. The work table can be folded up against the back board member and locked in a compactly folded configuration that also secures tools placed on the back board member within the folded work bench.
The present invention accordingly provides for a folding work bench movable between a folded configuration or partially folded configuration and an unfolded configuration. In one presently preferred embodiment, the folding work bench includes a generally planar work table having a top work surface, which is movable between a folded position extending in a longitudinal direction in the folded configuration and an unfolded position extending in a transverse direction substantially perpendicular to the longitudinal direction in the unfolded configuration. The work table typically has a durable top work surface, such as a laminated wood work surface, for example, and optionally may also include one or more sliding drawers mounted to the underside of the work table.
A plurality of front legs are pivotally connected to the front side of the work table, so as to be compactly foldable against the underside of the work table in the folded or partially folded configuration. The folding work bench typically has a pair of front legs, which optionally may include bottom folding end pieces, and which optionally may be connected together by a cross-brace.
The folding work bench includes a generally planar back board member extending in the longitudinal direction in the folded and unfolded configurations, which includes a pair of first support struts and a pair of second support struts mounted to the bottom side of the back board member. The pair of first support struts extend downwardly in the longitudinal direction from the bottom side of the back board member. The pair of second support struts extend in the transverse direction from the bottom side of the back board member and are pivotally connected to the left and right sides of the work table. In a presently preferred aspect, the back board member is a peg board for holding tools, and typically is a steel peg board.
A plurality of rear legs, typically a pair of legs, are pivotally connected to the pair of first support struts, and are movable between an upwardly folded position extending in the longitudinal direction adjacent to the back board member and a downwardly unfolded position extending downwardly from the pair of first support struts in the longitudinal direction for supporting the folding work bench. The folding work bench can assume a partially folded configuration in which the rear legs are unfolded to support the folding work bench with the work table and front legs in their folded positions, so that the folding work bench can be stored in the partially folded configuration in a standing position against a wall, ready to be unfolded for use. The rear legs optionally may include telescoping end pieces, and optionally may also be connected by a cross brace.
In a presently preferred aspect, the folding work bench includes one or more articulated struts having first and second links pivotally connected together. The folding work bench typically includes a pair of the articulated struts. For each articulated strut, the first link is pivotally connected to a front leg, and the second link is connected to one of the first support struts. The articulated struts extend in the transverse direction in the unfolded configuration, and extend in the longitudinal direction in the folded configuration.
The folding work bench advantageously preferably includes a top storage shelf mounted to the top side of the back board member and extending in the transverse direction from the back board member. The top storage shelf optionally may include a fluorescent light mounted to the underside of the top storage shelf, and optionally may include an electrical outlet on the underside of the top storage shelf.
In another presently preferred aspect, the folding work bench includes a locking device for locking the work table in a folded position. The locking device typically includes a pair of opposing locking pins connected to a locking handle. By turning the locking handle, the locking pins can be moved between an inwardly withdrawn unlocking position and an outwardly extending locking position. A pair of locking struts are mounted on opposing sides of the back board member and extend in the transverse direction toward the front of the folding work bench, and each of the opposing locking struts includes an aperture for receiving the locking pins when the locking pins are in their outwardly extending locking position. In this manner, tools on the back board member may be locked inside the folding work bench.
In another presently preferred embodiment, the present invention provides for a folding work bench movable between a folded configuration or partially folded configuration and an unfolded configuration, including a generally planar work table movable between a folded position and an unfolded position, a plurality of front legs slidably connected to the table member so as to be slidable between the front and rear sides of the table member, a plurality of rear legs pivotally connected to the rear side of the table member, and a generally planar back board member slidably connected to the plurality of rear legs. In a presently preferred aspect, the front legs are pivotally connected to the rear legs by a truss assembly of link members pivotally connected together. The table top member may include one or more sliding drawers, and a top storage shelf is typically mounted to the top side of the back board member.
Other features and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments in conjunction with the accompanying drawings, which illustrate, by way of example, the operation of the invention.
