Disclosed is a decontamination robot. The robot includes a decontamination box including at least two arrays of ultraviolet LEDs, the two arrays arranged to irradiate an object placed inside the decontamination box from at least two independent directions, the decontamination box further including an interior surface with at least 90% reflectivity of ultraviolet light. The robot also includes a drivetrain including four swerve-drive units, each swerve-drive unit capable of rotating a wheel on an axis of the wheel and capable of orienting the wheel in a plane defined by the axes of the four wheels of the four swerve-drive units, whereby the four swerve-drive units coordinate to generate translational motion of the decontamination robot on a working surface. The robot also includes a scissor lift capable of raising the decontamination box from a first position to a second position, wherein the scissor lift comprises a plurality of bars connected by a plurality of joints such that the plurality of bars form a series of crosses, and a top plate attached to a top of the decontamination box.

Cradle assemblies for supporting a door for uninstalling and/or installing the door to a fuselage of an aircraft, and arrangements and methods for the same are provided. In one example, a cradle assembly includes a first contoured board and a second contoured board that is spaced apart from the first contoured board. The first and second contoured boards are cooperatively configured to support outer sections of a first door. A third contoured board is configured to be selectively positioned adjacent to and extending higher than the first contoured board to support a first outer section of a second door that has a different outer shape than the first door. The third contoured board is contoured to substantially match the first outer section of the second door. The cradle assembly is configured to be positioned proximate to the fuselage.

The present invention relates to a scissors lift comprising a bottom frame, a top frame and a scissors mechanism arranged between said bottom frame and said top frame to displace said bottom frame and said top frame relative to each other by transfer of an actuation force. The scissors mechanism comprises a central hollow scissors arm delimited between opposite scissors arm surfaces, wherein said central hollow scissors arm has a bottom pivotal connection connecting it to said bottom frame and a top pivotal connection connecting it to said top frame. Further, the mechanism comprises two passive scissors arms being pivotally connected to said bottom frame and pivotally connected to said top frame. Each of said two passive scissors arms are pivotally connected to said central hollow scissors arm on said opposite scissors arm surfaces of said central hollow scissors arm. Further, the scissors lift comprises a motor providing said actuation force, said motor located between said opposite scissors arm surfaces of said central hollow scissors arm. Thereby, the motor may be protected and at least partially enclosed by the scissors lift and even by the central hollow scissors arm, allowing a safer and/or more easily maintained scissors lift.

According to the present disclosure, a projector lift is provided to raise and lower a projector from the ceiling. The projector lift includes a ceiling mount normally coupled to the ceiling, a projector mount supporting the projector, a lift assembly configured to raise and lower the second mount and projector, and a stabilizer extending between the ceiling and projector mounts.

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 shoe tying support assembly includes a frame that is positionable on a floor. A scissor lift is movably coupled to the frame and the scissor lift is actuatable between a lifted position and a lowered position. A platform is positioned on the scissor lift and the platform is spaced upwardly from the frame when the scissor lift is actuated into the lifted position. Thus, a user can position their foot on the platform for assisting with tying shoes. A tilting unit is coupled between the scissor lift and the platform and the tilting unit tilts the platform at a selectable angle of deflection from a horizontal plane to enhance comfort for the user to position the user's foot on the platform. A remote control is provided to remotely control the scissor lift and the tilting unit.
