Abstract

A powered retractable motorcycle stand is disclosed having a stationary upper assembly mounted to a motorcycle and a moving lower assembly for ground contact. The stationary assembly includes a horizontal driven shaft coupled to an electric motor coupled. Gear reduction means transfers torque from the horizontal shaft to a vertical screw shaft that extends to a ground contact position and retracts into a protective housing. The vertical screw shaft is pinned so that it does not rotate and is restricted to linear movement. A safety device to prevent operation of the motorcycle while the stand is engaged is included. Motorcycle anti-theft means are also included.

Claims

What is claimed is:

[Claim 1] A powered retractable motorcycle stand comprising: a stationary assembly mounted to a motorcycle by mounting means, said stationary assembly comprising a horizontal driven shaft coupled to shaft driving means which is in turn coupled to; gear reduction means which is in turn coupled to; a moving assembly comprising a vertical driven shaft with ground contact means adapted for motorcycle support, wherein said powered retractable motorcycle stand further includes moving assembly control means and motorcycle anti-theft means.
[Claim 2] The stand as claimed in claim 1 wherein said horizontal driven shaft has a first end and a second end, and wherein said shaft driving means comprises an electric motor coupled to the horizontal driven shaft first end.
[Claim 3] The stand as claimed in claim 2 wherein said vertical driven shaft is a threaded vertical screw gear having an axis, a first end and a second end, and wherein said second end has an unthreaded portion adjacent thereto.
[Claim 4] The stand as claimed in claim 3 wherein said horizontal driven shaft second end is coupled to said gear reduction means, and wherein the gear reduction means is adapted to transfer torque from the horizontal driven shaft to the threaded vertical screw gear.
[Claim 5] The stand as claimed in claim 4 wherein the gear reduction means comprises a worm gear coupled to the horizontal shaft second end and a spur gear having an outside diameter having cogs for meshing contact with said worm gear and a threaded inside diameter for meshing contact with the threaded vertical screw gear, and further wherein said gear reduction means is housed in a gear housing.
[Claim 6] The stand as claimed in claim 5 wherein the threaded vertical screw gear is rotationally fixed by fixing means with respect to said spur gear.
[Claim 7] The stand as claimed in claim 6 wherein said fixing means comprises an linear co-axial keyway within the threaded vertical screw gear and a fixed key having a first end and a second end, wherein said key first end is in sliding relationship with said co-axial key way and said key second end is fixed to said gear housing, the result being that rotation of the threaded vertical screw gear is prevented by the key first end and rotation of the spur gear around the threaded vertical screw gear results in a linear vertical movement of the threaded vertical screw gear from a first retracted position to a second extended position.
(Claim 8] The stand as claimed in claim 7 wherein the stationery assembly further comprises a housing adapted to protectively house the threaded vertical screw gear in said first retracted position.
[Claim 9] The stand as claimed in claim 8 wherein said mounting means comprises a mounting block having dowel means adapted for mounting said mounting block to the motorcycle and fastening means adapted for mounting the mounting block to a gear housing first side;
and, a mounting bracket having a first end for mounting to a gear housing second side and a second end for mounting to the motorcycle.
[Claim 10] The stand as claimed in claim 9 wherein said ground contact means for motorcycle support comprises a ground contacting angle member having a ground contacting horizontal portion having a central aperture, a vertical flange portion, and a ring member fixed over said central aperture and adapted to receive said unthreaded portion of the second end of the threaded vertical screw gear.
[Claim 11] The stand as claimed in claim 10 wherein said moving assembly control means comprises a DC power source for energizing the control means, said DC power source connected to a circuit breaker for circuit protection, said circuit breaker connected to a reversing polarity contactor for reversing the polarity of said electric motor thereby permitting forward and backwards rotation thereof; and, the electric motor for raising and lower the moving assembly.
[Claim 12] The stand as claimed in claim 11 wherein the control means further comprises an up/down switch connected to relay switch means, said relay switch means in turn connected to said reversing polarity contactor for engaging the electric motor in a desired direction thereby lowering or raising the stand; first limit switch means adapted to permit only upward motion of the stand when the stand is in ground contact; and, second limit switch means adapted to permit only downward motion of the stand when the stand is in its retracted position.
[Claim 13] The stand as claimed in claim 12 wherein the control means further comprises safety switch means comprising a motorcycle engine stop switch having an off position and an on position and connected to safety relay means which is in turn connected to said up/down switch so that said motorcycle engine will run only when the stand is in its retracted position or when the motorcycle is in neutral gear.
[Claim 14] The stand as claimed in claim 13 wherein the up/down switch further includes an indicator light indicating that the stand is not retracted.
[Claim 15] The stand as claimed in claim 14 wherein said anti-theft means comprises relay means adapted to isolate the electric motor from the battery when the stand is extended and the key has been removed from the starter relay so that the stand cannot be retracted when the key has been removed.
[Claim 16] A powered retractable motorcycle stand comprising a stationary assembly mounted to a motorcycle by mounting means and a moving assembly operatively connected to said stationary assembly, wherein the stationary assembly comprises a horizontal driven shaft having a first end and a second end; an electric motor coupled to said horizontal shaft first end; gear reduction means coupled to said horizontal shaft said second end, wherein said gear reduction means is adapted to transfer torque from the horizontal driven shaft to said moving assembly.
[Claim 17] The stand as claimed in claim 16 wherein the moving assembly further comprises a threaded vertical screw gear having an axis, a first end and second end, wherein said first end is coupled to said gear reduction means and said second end is coupled to a ground contacting a ground contacting angle member.
[Claim 18] The stand as claimed in claim 17 further comprising moving assembly control means and motorcycle anti-theft means.
[Claim 19] The stand as claimed in claim 18 wherein the gear reduction means comprises a worm gear coupled to the horizontal shaft second end and a spur gear having an outside diameter having cogs for meshing contact with said worm gear and a threaded inside diameter for meshing contact with the threaded vertical screw gear, wherein said gear reduction means is housed in a gear housing.
[Claim 20] The stand as claimed in claim 19 wherein the threaded vertical screw gear is rotationally fixed by a linear co-axial keyway within the threaded vertical screw gear and a fixed key having a first end and a second end, wherein said first end is in sliding relation with said co-axial key way and said second end is fixed to said gear housing the result being that rotation of the vertical screw gear is prevented by the key first end and rotation of the spur gear around the threaded vertical screw gear results in a vertical linear movement of the threaded vertical screw from a first retracted position to a second extended position; and wherein the stationary assembly further comprises a housing adapted to protectively house the threaded vertical screw gear in said first retracted position.
