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.

The present system is directed to a modular apparatus that may be assembled and disassembled repeatedly without the use of tools. The modular system includes connectors that may be fixed to the underside of a plank and then engaged with leg portions. The connectors further include channels to accommodate retention members of additional attachments, such as covers, guards, signage, or racks that may be added onto the modular apparatus to increase its utility. The retention members mate with the connectors to connect and securely hold the attachment and can be removed from the connectors all without the need for tools.

A tool cabinet includes a cabinet body having two guide rails and a routing space that is proximate to one of the guide rails, a working platform unit having a protective tube, two lifting units, a driving unit, and a power supply unit having a transmission wire. The working platform unit includes two extension members respectively slidable relative to the guide rails. Each lifting units includes a threaded rod extending through a respective extension member. The driving unit is disposed for driving rotation of the threaded rod of a respective one of the lifting units. The transmission wire has an end connected to the driving unit, and an opposite end extending through the protective tube into the routing space.

A storage apparatus includes trays, a shaft, a base element and two wheel assemblies. The shaft is inserted in the trays to connect the trays to one another so that each of the trays is rotatable between a withdrawn position and a spread position relative to a lower one of the trays. The base element is attached to the shaft. The base element is connected to a second one of the trays by a connecting element. The base element is located below the lowermost tray when the trays overlap one another. The first wheel assembly includes wheels attached to the lowermost tray. The second wheel assembly includes wheels attached to the base element. The wheels cover a first area when the trays overlap one another and cover a second area when the trays fully spread from one another. The first area is smaller than the second area.

A tool cabinet includes a cabinet body having two guide rails, a working platform unit having a movable platform member and two hollow extension members, two lifting units each having a threaded rod, two driving units, and a control unit. The extension members are respectively slidable relative to the guide rails. The threaded rods respectively extend through the extension members and telescopically into the guide tubes. Each driving unit has a motor, and a speed reduction mechanism driven to rotate the threaded rod of a respective lifting unit. The control unit is connected to the motors for synchronizing movements of the motors.

A convertible sawhorse and worktable including a sawhorse assembly having first and second outer-facing side surfaces and a worktable top assembly arranged for selectable positioning relative to the sawhorse assembly, the worktable top assembly including a worktable surface defining element and a worktable auxiliary support assembly, the worktable top assembly having at least two operative orientations including a storage operative orientation wherein the worktable surface defining element is located adjacent the first outer-facing side surface of the sawhorse assembly and the worktable auxiliary support assembly is located adjacent the second outer-facing side surface of the sawhorse assembly and a worktable usage operative orientation wherein the worktable surface defining element is located above the sawhorse assembly and the worktable auxiliary support assembly is located adjacent the second outer-facing side surface of the sawhorse assembly.

A workstand support can have a height adjustment mechanism using a multi point locking system for simultaneously lock and unlock multiple locations in the height adjustment mechanism. Latch configurations of the multi point locking system can provide high surface areas for higher load support. Snap latches and spring loaded assemblies can provide means to secure the multi point locking system. Folded legs can reduce storage space for the workstand support.

Provided is a sawhorse including two rigid frame members pivotally articulated to one another. Each frame member includes two legs wherein at least one leg of each frame member is an extendible leg including a support leg portion, an extension member coaxially extending therewithin and a locking mechanism actuatable by one or more manipulation member. The extension member is displaceable between a fully retracted position and a fully extracted position. The arrangement is such that extraction of the extension member is facilitated without requiring manipulation of the manipulation member actuating the locking mechanism while the retraction displacement of the extension member is facilitated only upon manipulating the manipulation member to actuate the locking mechanism to thereby allow retraction of the extension member into the support leg portion.
