The lock release member includes an elongated element disposed below the upper surface of the table and extending along the table toward the handle, and the lock of the table is released when the user pulls the elongated element in the longitudinal direction of the elongated element. According to the invention, the user can release the lock of the table simply by pulling the elongated element, so that ease of lock releasing operation is enhanced.

  • Patent number: 7604027
    Abstract: A retractable workbench is provided that is mounted to a vertical surface such as a wall. The workbench is retractable between a horizontally oriented deployed position, and a vertically oriented retracted position. The workbench is vertically adjustable along wall mounts. Bench mounted tools may be mounted on rotatable panels, and the panels may be inverted when the workbench is retracted, thereby allowing the workbench to be fully rotated to the vertically oriented retracted position without removing the tools. Storage of tools and hardware may be achieved by a rotatable mounting surface that attaches to the workbench. Workbench legs that support the workbench when deployed are also retractable, and the legs may be adjusted for height and securely attached to the floor for additional stability.

  • Patent number: 7555976
    Abstract: The subject invention provides a portable saw table assembly for cutting a material longitudinally, laterally, and at various angles thereto. The assembly includes a first and a second table rail being parallel and spaced from each other and each extending between a proximal end and a distal end. A saw rail is moveably supported by the first and the second table rails for moving longitudinally along the table rails between the proximal and the distal ends and a mounting plate is moveably supported by the saw rails to allow movement of the mounting plate laterally along the saw rail between the first table rail and the second table rail. A saw plate is rotateably supported by the mounting plate for carrying a saw to cut the material. A guide bar is disposed diagonally relative to the first and the second table rails and engages the saw plate to guide the saw plate diagonally in response to simultaneous movement of the saw rail longitudinally and the mounting plate laterally.

  • Patent number: 7543614
    Abstract: A collapsible infeed/outfeed table is provided with a pair of collapsible wings that are supported by struts slidably attached to the wings and pivotally attached to two pairs of elongated support legs. A pair of vertical stanchions provide a pivot point for the wings and lower ends thereof support a pair of sliding braces also connected to the extensible legs. A central roller is provided between the two wings that telescope between an extended and a retracted position. Extensible rollers are provided at free ends of the wings such that, when extended, the table may serve as a crosscut saw support stand. With the wings retracted and the central roller raised, the table may serve as an infeed/outfeed roller support for a separate saw, such as a crosscut saw or table saw. Finally, with all of the rollers retracted and the wings extended, the table is a work table.

  • Patent number: 7530377
    Abstract: An improved portable work bench includes a structural body, and a platform disposed on the structural body. In addition, the platform includes a cam mechanism for locking the position of the platform along the structural body. Further, the portable work bench may include a plurality of legs for supporting the structural body. The structural body may be tubular and preferably has a square cross-section. Accordingly, the user need only place the platform in any position along the length of the structural body and move the cam mechanism to lock the platform in place. The cam mechanism may include a cam pivotally attached to the platform near the structural body, so that when the user rotates the cam, the cam contacts the structural body, locking the platform. A plate may be disposed between the cam and the structural body. The plate may have a hook portion, which contacts the bottom surface of the structural body.
