A cabinet lifting assembly for lifting overhead cabinets for installation includes a scissor lift that is positionable between a lifted position and a lowered position. The scissor lift includes a base, a top, a pair of scissors and a screw extending between the scissors. A fitting is coupled to the screw to be engaged by a chuck on a drill thereby facilitating the screw to be rotated in the first direction or the second direction. A panel is coupled to the top of the scissor lift. A support is coupled to the panel such to have an overhead cabinet positioned thereon thereby facilitating the scissor lift to lift and lower the overhead cabinet for installation.

In general, a scissor jack is described. A typical embodiment includes four arms (4) hingedly arranged to provide two opposite elbows between a base (10) and a load support (11), a pair of trunnions (2, 2.1), one at each elbow connected by a partially threaded shaft (12) with one end of the shaft rotatably engaged in the threaded trunnion (2.1) to extend beyond the outer corner of the elbow.

Located on the shaft and between the outer two trunnions is an assembly comprising a pair of levers (3) pivotally assembled on a third trunnion (5) which forms the one end of a double yoke (1) comprising two rods slideably passing through the outer trunnion (2) and beyond the elbow. In contact with and operating against the inner trunnion (5) is a thrust bearing (9) fixed in portion on the shaft by means of a flange. Springs (6) are attached to individual levers and the corresponding arms for alignment purpose.

Fully collapsed the angle of operation of the first stage of the lever in contact with the pivot point (8) is such that it simulates the same optimum angle of a typical scissor jack at approximately 75% of it's range. Once the first stage of the lever is fully extended the second stage takes over at pivot point (7) when it is again at the optimum angle. Once the second stage of the sever is fully extended the jack itself is in an optimum height for further lifting. Thus the jack is able to utilise the full extent of it's range of motion.

A scissor jack comprises a bracket coupled to a first upper arm and a second upper arm; a load rest positioned above the bracket and pivotally connected to the bracket; an elastic element disposed between the load rest and the bracket; a base coupled to a first lower arm and a second lower arm; a first connector pivotally connected to the first upper arm and the first lower arm; a second connector pivotally connected to the second upper arm and the second lower arm; and a driving rod drivably connected to the first and second connectors.

A scissor jack kit to elevate each vehicle quadrant for maintenance including one scissor jack for each wheel. Each scissor jack includes a parallelepiped bottom base, a lower support base atop thereof, and mirror image first and second arms, each having top and bottom ends hinged at a central elbow. Each of proximal and distal ends of the bottom and top ends, respectively, pivotably couples to the respective lower and upper support base. An aperture in the central elbow receives a rotatable leadscrew therethrough having a socket with a hole which receives a hook of a jack speed crank handle to rotate the leadscrew to adjust the scissor jack height. Mount holes in the upper support base provide for chassis mounting. A groove in an axle mount body on the upper support base supports the axle proximal the respective wheel and has a cushioned lining thereon.

A table device and a printing apparatus are provided. The table device includes a X-shaped link member in which two long members are turnably coupled in an X-shape, an expansion/contraction mechanism that expands/contracts with at least a pair of X-shaped link members arranged facing each other, a table that is disposed on one end side of the expansion/contraction mechanism and moves in the expansion/contraction direction of the expansion/contraction mechanism, a support member disposed on the other end side of the expansion/contraction mechanism, a coupling member that couples the opposing long members of the long members forming the expansion/contraction mechanism and moves with the expansion/contraction of the expansion/contraction mechanism, and a regulating member that regulates a fluctuation of the coupling member that moves when the expansion/contraction mechanism expands/contracts.

A device comprising a main support an equipment support having a first position and a second position adjustable relative to the height of the main support. A first crank lever is mounted to the first bearing and rotatable about a first rotational axis via a first shaft. A connecting rod is connected to the first crank lever via a first joint and to the equipment support via a second joint. A guide is arranged such that the equipment support is displaceable while guided to remain parallel to the main support. The equipment support passes an upper dead center position when moving from a first to a second position by rotation of the first crank lever and, upon further rotation a stop element contacts a stop.
