  • Patent number: 11312000
    Abstract: The invention discloses a workbench, comprising: a folding base comprising a left support frame and a right support frame cross connected with each other by a pivot and a handle rod connected with tops of the left support frame and the right support frame; a movable plate fixed on the left support frame and provided with at least one first fixing hole; a fixed plate fixed on the right support frame and provided with at least one second fixing hole; the movable plate and the fixed plate are spread out on the upper surface of the folding base as the left support frame and right support frame are unfolded; and the movable plate and the fixed plate are folded downwards along both sides of the handle rod as the left support frame and the right support frame are furled. The present invention allows the workbench to be folded by folding downwards the movable plate and the fixed plate, such that the workbench occupies less space and the folded workbench is more secure.

  • Patent number: 8522769
    Abstract: The present invention relates to outdoor grill accessories, and more particularly, a foldable worktable attachment for an outdoor grill that includes a large table area that is interconnected to a lower shelf by two sets of foldable legs. When in an erect position, the table provides ample space for preparing foods and the like, but when in a collapsed position, the table lies flush against one of the sides of the grill housing, thus, enclosing the lower shelf and supporting legs that are folded and stored between the table and a recessed area included in the grill housing.

  • Patent number: 5974979
    Abstract: Portable folding tables which are particularly adapted for massage and other body therapy uses wherein each table includes two top sections which are hingedly connected at one end and which are supported by legs which are pivotally connected thereto. Each leg is reinforced by either a longitudinal pivotally folding brace, a guide assembly or a positive stop member. The legs, and reinforcing braces when used, are automatically deployed and stabilized by cable systems which extend both longitudinally and diagonally relative to the table legs.

  • Patent number: 5660121
    Abstract: A folding framework (18) for a ramp section (12) includes folding legs (20). The legs include extendable members (24) extending between the sets of legs with an inner sliding member (28) and a outer sliding member (26) providing for folding motion. The sets of legs (20) both fold inward to a storage position wherein extendable members (24) and the legs (20) lie substantially flat against the underside of a supportive deck (14). The extendable members (24) include an angled end portion (32) which extend downward and pivotally mount to the legs (20) for offsetting the extendable members (24) from the legs (20) when in the folded position.

  • Patent number: 5544592
    Abstract: A table for use in a spray booth is foldable against a support wall when not in use. Telescoping arms engage opposite ends of the table and are pivotally mounted to the support wall so that the table is easily foldable against that wall when the telescoping arms are fully retracted. The table may be positioned in differing spatial relationships from the support wall when deployed into its operative configuration due to the telescoping arms. The table is supported by foldable legs that are foldable under the table, and the legs are interlocked to one another so that folding or unfolding one leg accomplishes folding or unfolding of the other legs as well. A pair of handles facilitates folding and unfolding of the table and a step facilitates climbing onto and descending from the table. A worker standing on the platform may walk along its length and reach any part of a vehicle parked in the spray booth due to the elevation provided by the table.

  • Patent number: 4354436
    Abstract: A trolley for supporting and transporting units of electronic equipment is provided with a front pair of legs and a rear pair of legs, with horizontal members being integrally formed with each pair of legs. A platform is supported upon the horizontal member of the rear legs and upon a mount member rotatably mounted upon the horizontal member of the front pair of legs. Supporting brackets are fixed to each of the rear legs, upon which are attached retaining brackets, with the horizontal member of the front legs being retained within these retaining brackets in rotatable manner. Link members are rotatably coupled to the lower ends of the legs, in such a way that the entire assembly may be folded together into a very compact space. Greatly increased strength and rigidity by comparison with conventional trolleys is ensured.

  • Patent number: 4155386
    Abstract: The invention is directed to a foldable, portable workbench having a work table and a support structure for supporting the work table. The support structure includes a pair of mutually spaced leg assemblies and each of these leg assemblies, in turn, includes a pair of legs pivotally connected at one end thereof to the work table. Articulated linkages pivotally interconnect, respectively, the two legs of each pair of legs to each other and at least one of the legs to the work table. The articulating linkages are connected so that the work table and leg structures are stacked in juxtaposition to each other when the workbench is in its folded position and, so that the other ends of the leg structures are spread apart from each other with the work table substantially transverse to the leg structures when the workbench is in the erected position.
