Abstract: A lifting system for lifting a lifting platform through use of a lifting assembly. The lifting assembly having a vertical support rail and a control arm that is pivotally connected to the vertical support rail about a first pivot axis. A support beam being connected to the lifting platform the support beam having an engaging member near its proximal end that engages the vertical support rail to provide translational movement of the support beam along the vertical support rail. The control arm having an engaging member engaging the support beam at a location spaced from the vertical support rail to provide translational movement of the engaging member with respect to the support beam. A stabilizer arm is pivotally connected to the control arm and pivotally near the proximal end of the support beam. Movement of the lifting platform causing translational movement of the engagement members.

Abstract: A stowable platform is connected to a frame with a first and second trolley, each trolley is moveable inside a channel and has an upper and lower roller. The lower rollers are tied to a mechanism that moves them in the channels in a linear motion. The upper rollers are in contact with one side of the channel from the offset center of gravity in the platform. The platform moves between a stored position defined by the lower roller near a terminal end of the channel and a use position defined by the upper roller located in an overhanging end of the channel and the lower roller closer to the overhanging end than the terminal end.

Abstract: A drive mechanism having a first and second side plate opposite each other that rotatably hold an engagement shaft and a gear shaft. A rack passes between the gear shaft and engagement shaft. The first and second side plates are allowed to float vertically in a frame. The gear is maintained in constant contact with the rack when the rack is moved vertically within the frame.
