A fixture for dumpster bottom replacement is provided including four vertical support legs, three fixed horizontal supports, with each horizontal support attached to two vertical supports, one slidable horizontal support which is slidably attached to two fixed horizontal supports, four upper supports which are integral with the vertical support legs or attachable to the vertical support legs and the upper supports comprise a plurality extension supports and one or more push pin assemblies. A kit for dumpster bottom replacement includes a fixture for dumpster bottom replacement as described above and a lift table including a surface capable of holding a dumpster that is vertically adjustable in height. A method of using a dumpster bottom kit includes placing a dumpster on the fixture with the lift table, securing the dumpster with a slidable horizontal support, removing the bottom of the dumpster and welding a new bottom onto the dumpster.

A carpenter's accordion is disclosed herein. The carpenter's accordion is a portable, compactable, and free-standing tool that may be advantageously used in combination with a table saw to increase the length of stock that one user can cut with a blade. Generally, the more sections that comprise the carpenter's accordion, the greater the lengths of stock one user will be able to cut using a table saw or other similar tool in combination with the accordion.

An integrated folding foot rest includes a table-board supporting seat, the bottom of which is provided with four break angle bending portions. Each of the break angle bending portions is connected to a leg folding mechanism. The leg folding mechanism includes a pedestal, a rotating seat and a leg. The pedestal is formed by symmetrically splicing a front pedestal and a back pedestal. Lower portions of the front and back pedestals are respectively provided with rotary limiting grooves, and two end portions of the rotary limiting grooves are respectively provided with limiting ends. One side of the rotating seat is provided with a telescopic slideway, the telescopic slideway is internally provided with a T-shaped locking piece, two ends of a limiting portion of the locking piece are correspondingly embedded into the rotary limiting grooves, respectively, and a pressure spring is annularly sleeved on the telescopic portion of the locking piece.

Workstation for performing a task on a workpiece using a tool. Some implementations of the invention allow an adjustable shelf to be used to position a workpiece on the workstation. Some implementations of the invention include a support bar for partially supporting a tool as the task is performed on a workpiece coupled to the workstation. Some implementations of the invention allow a workpiece to be positioned at a reference location or orientation relative to the workstation. Some implementations of the invention allow a tool to perform an action based on determining the position of the tool relative to the workstation using computer vision techniques to analyze a feature of the workstation.

A convertible rolling workbench supports a worker when sitting or kneeling. The workbench includes a bench structure that can be used alone or selectively attached to a dolly. The bench structure includes two vertical leg assemblies. Each leg assembly includes two legs and upper and lower support bars extending between the two legs near their first and second opposite ends. The bench structure is affixed to the two leg assemblies and offset from the workbench's horizontal center axis. The dolly includes two horizontal frame members and an intermediate planar member extending between them. Attached to each horizontal frame member is a caster wheel. Each frame member includes a receiver configured to receive said first or second ends of the vertical legs on said leg assemblies. The user may also rotate the bench seat assembly over the dolly or directly over a support surface to position the seat at different elevations above the support surface. Locks are provided to prevent the dolly from rolling over a support surface. The intermediate planar member may be a wide tray used to hold tools in one embodiment.

A convertible sawhorse and work table assembly includes two sawhorse legs, a worktable and two pivoting support rods. The two support rods are pivotably attached to the work table near one end thereof and to one of the sawhorse legs at the other end thereof. When in the closed condition, the sawhorse legs are folded against each other, with the worktable folded along one of the legs and the two support rods folded against the other sawhorse leg. In a second condition, the sawhorse legs are pivoted away from each other with the worktable and support rods remaining folded against the legs. In a third condition, the table is pivoted upwardly away from the one sawhorse leg until it is disposed substantially horizontally above the sawhorse legs, and is then slid rearwardly relative thereto until the pivot support rods are fully extended away from the other sawhorse legs.
