Description
- This application claims priority on U.S. Provisional Application Ser. No. 60/580,707, filed Jun. 21, 2004, titled REMOVABLE TOOL SUPPORT FOR WORKBENCH and is included herein in its entirety.
- 1. Field of the Invention
- This invention relates to trestles, and specifically relates to trestle extensions that can support tools.
- 2. Description of Related Art
- Construction workers use trestles to support lumbers or panels at an appropriate height. Prior art trestles have a top portion supporting the panels or the lumbers. The top portion is supported by a plurality of legs. Usually, four legs are connected to the top portion. The legs may be foldable thus providing easy transportation of the trestle.
- Workers using trestles are using the top portion of the trestle to support the material they need to work with. The top portion of the trestle, normally an horizontal member such as a commonly called 2×4, is therefore not available or unusable to support tools. The size of the top portion is usually too narrow to really be helpful to support a tool. Workers must put their tools on the ground when they need both hands for manipulating material on the trestle. Tools on the ground are subject to dirt or to be hurt by the feet of the worker or contact the bench's legs. Movements needed by the worker to access the tools on the ground are not ergonomic and can promote back pain or other injuries.
- Other prior art trestles offer room to support tools within the body of the trestle. Positioning tools within the trestle does not provide easy access to tools when lumbers are positioned on the trestle. The tool support being part of the trestle may add additional weight to the bench when not needed for the work performed with the bench. Moreover, fixed tool support may be cumbersome.
- In the past, tool supports for workbenches or trestles have been positioned, as described in U.S. Pat. Nos. 5,875,828, 5,862,731 and 5,592,981, on the top portion. This positioning of the tool support on the trestle precludes any complete use of the top portion to support over sized sheet panel for instance.
- Existing tool supports for trestles or workbenches are generally extending higher than the top surface of the top member of the trestle. The tool support is often built into the trestle's top portion therefore not permitting natural positioning of the tools on the trestle further from the trestle's top portion.
- Tool supports on trestles are practical when the user uses tools but can become cumbersome when no tools are needed to perform the work.
- Consequently, a need has been felt for providing an improved trestle tool support over the existing prior art.
- The present invention satisfies the above-described needs by providing an improved trestle over the prior art.
- Accordingly, one aspect of one or more embodiments of this invention provides a modular tool support that can be removed from the trestle when not needed. A mechanical connection is made between the tool support and the frame of the trestle. A fastener removably locks the tool support to the trestle.
- An aspect of the present invention disposes a removable tool support on a trestle at least partially outside the volume defined by the plane created by the ground contacting portion of the trestle's legs when the trestle is on substantially flat ground, the perimeter of the plane vertically extending to the level of the uppermost portion of the trestle's top member.
- An aspect of the present invention disposes a removable tool support on a trestle at least partially inside the volume defined by the ground contacting portion of the trestle's legs when the trestle is viewed from one end of the top member and is on substantially flat ground extending vertically to the level of the uppermost portion of the trestle's top member minus the volume defined between the legs of the trestle when still axially viewed from one end of the top member.
- Yet another aspect of the present invention is to disposed the removable tool support on a side of the trestle's top member.
- Another aspect of one or more embodiments of the present invention provides a tool support for trestles disposed on the side of the trestle.
- Another aspect of one or more embodiments of the present invention provides a tool support that is lower than the top member of the trestle. The tool support is disposed lower on the trestle allows the highest portion of the tool maintained on the support to be lower than the upper surface of the top member.
- Another aspect of one or more embodiments of the present invention provides a tool support that leaves free the top surface of the top member of the trestle.
- According to a further aspect of one or more of these embodiments, the top surface of the trestle can support oversized lumber without limiting the trestle tool support to maintain tools.
- According to a further aspect of one or more of these embodiments, the tool support can support a “skill saw” with the blade perpendicular to the top member and lower than the top member. The tool on the support can be ergonomically aligned for the user of the trestle to use the tool.
- According to a further aspect of one or more of these embodiments the tool support can support a “skill saw” with the blade parallel to the top member and lower than the top member.
- According to a further aspect of one or more of the embodiments, the tool support maintains the tools needed by the user of the trestle at a constant position thus preventing the user to search the tools.
- Another aspect of one or more embodiments of the present invention provides a removable tool support that can be folded to reduce its size when stored. The support of one embodiment of this invention has a frame and a leg pivotably connected to the frame. The leg is perpendicular to the frame when in use with the trestle and can be folded parallel to the frame when stored. The result is a flat tool support to be stored as opposed to the larger volume defined by the frame and the leg in the perpendicular position.
- Additional and/or alternative advantages and salient features of the invention will become apparent from the following detailed description, which, taken in conjunction with the annexed drawings, disclose preferred embodiments of the invention.
