ABSTRACT:
An integrated device for securing a wheelchair in a position on a floor is formed of a frame-like box for mounting beneath the floor and within an opening therein. The box mounts for rotation about parallel horizontal axes, a pair of laterally spaced, horizontally extending parallel flaps which are rotatable from a position flush with a pair of openings within a horizontal floor plate receiving the flaps to raised, oppositely oblique positions forming a V. A vertically upright cover extends from one end of the floor plate and mounts a pair of push button controls on an upper surface. A vertically upright actuator is fixedly mounted to a face of the upright cover and has a projectable and re tractable plunger coupled to a flap locking member which carries an axial projection projectable into an axial bore of a retaining cylinder fixedly mounted to the box. Wings to opposite sides of the flap locking member couple via connecting rods to respective pivotable rocker arms which fixedly mount rocker arm drive rods fixed to the hinged flaps for rotating the flaps in opposite directions. The connecting rods move into axial alignment, thereby ensuring force take-up by the flap locking member, with the flaps in oblique raised position. A vertically upright channel guide member receives a flap locking member having a slide fitted to a channel guide member allowing forces developed on the hinged flaps to be taken up by the channel guide member during opening and closing of the flaps.
