Electric wall bed and leg extender

A wall bed system comprising:

• a frame for a wall bed;
• a bed leg for the wall bed;
• a rack plate with a T-shaped slot and a plurality of protrusions extending upright relative to the rack plate, the rack plate being movable relative to the frame between a first position, a second position, and a third position;
• a pinion plate rotatably coupled to the frame, the bed leg connected to the pinion plate, the pinion plate comprising a plurality of extensions that extend upright relative to the pinion plate, and a lock pin movable within the T-shaped slot;
• wherein when the rack plate is in the first position, the lock pin is positioned in a first location within the T-shaped slot, and as the rack plate moves from the first position to the second position, a first extension of the plurality of extensions engages a first protrusion of the plurality of protrusions, wherein engagement between the first extension and the first protrusion rotates the pinion plate in relation to the rack plate in a first direction from a first pinion plate orientation to a second pinion plate orientation that is approximately 90 degrees (“°”) from the first pinion plate orientation, wherein the bed leg rotates with the pinion plate;
• and
• wherein when the rack plate is in the second position, the lock pin is positioned in a second location within the T-shaped slot, and as the rack plate moves from the second position to the third position, a second extension of the plurality of extension engages a second protrusion of the plurality of protrusions, wherein engagement between the second extension and the second protrusion rotates the pinion plate in relation to the rack plate in the first direction from the second pinion plate orientation to a third pinion plate orientation that is approximately 90° from the second pinion plate orientation.

An rotation apparatus comprising:

• a rack plate with a T-shaped slot and a plurality of protrusions extending upright relative to the rack plate, the rack plate being movable relative to a frame between a first position, a second position, and a third position, the frame comprising a bed frame of a wall bed, the rack plate moving in a direction substantially horizontal to the frame when moving from between the first position and the third position, the rack plate slidably coupled to the frame;
• a pinion plate rotatably coupled to the frame, the pinion plate comprising a plurality of extensions that extend upright relative to the pinion plate, and a lock pin movable within the T-shaped slot, the pinion plate coupled to a bed leg;
• and
• a rod connected to the rack plate, the rod moving the rack plate from the first position to the third position when the rod moves from a retracted position to an extended position, wherein the rod moves from the retracted position to the extended position as the frame moves from a vertical position to a horizontal position,
• wherein when the rack plate is in the first position, the lock pin is positioned in a first location within the T-shaped slot, and as the rack plate moves from the first position to the second position, a first extension of the plurality of extensions engages a first protrusion of the plurality of protrusions, wherein engagement between the first extension and the first protrusion rotates the pinion plate in relation to the rack plate in a first direction from a first pinion plate orientation to a second pinion plate orientation that is approximately 90 degrees (“°”) from the first pinion plate orientation;
• and
• wherein when the rack plate is in the second position, the lock pin is positioned in a second location within the T-shaped slot, and as the rack plate moves from the second position to the third position, a second extension of the plurality of extension engages a second protrusion of the plurality of protrusions, wherein engagement between the second extension and the second protrusion rotates the pinion plate in relation to the rack plate in the first direction from the second pinion plate orientation to a third pinion plate orientation that is approximately 90° from the second pinion plate orientation.
