## Title
Motorcycle automatic balancing stand and methods

## Abstract

An automatic balancing stand and a method for supporting a motorcycle in an upright position are disclosed. The stand comprises a motion sensor coupled to a controller housed in an housing that signals a pump when the motorcycle changes speed. The housing is coupled to a hydraulic pump assembly comprising at least a pump, valve mechanism and hydraulic fluid. The stand further comprises a pair of members which are each coupled to a slidable member coupled to a wheel. Another end of the pair of members is coupled to the hydraulic pump assembly. The motion sensor signals the controller, activating the pump when the motorcycle slows to a preset speed, causing the pump to activate hydraulic pistons within each one of the members, extending the slidable members fully when the motorcycle is stationary. The slidable members are retracted when the motorcycle moves above the preset speed.

## Background
FIELD OF THE INVENTION
This invention relates generally to stands for motorcycles, and more specifically to, automatic balancing stands for supporting stationary motorcycles in an upright position and methods for providing support for a stationary motorcycle in an upright position.
BACKGROUND OF THE INVENTION
In the past, there have been a number of devices for supporting a motorcycle in an upright position when it was desired to keep the motorcycle stationary, such as during parking of the motorcycle. The simplest of these devices for motorcycles required physical contact with a kick stand pivotally connected to the motorcycle frame. When a motorcycle was stopped, the stand was kicked to an operative extended position to support the motorcycle on the ground. The stand was lifted into the non-extended position to allow the motorcycle to proceed. Riders either needed to support the motorcycle with their feet or get off the motorcycle to release the kick stand.
Currently, a number of more complex stands have been proposed that require mechanical interactions between components such as gears that may result in unreliability due to mechanical breakdown. Many of the stands that have been proposed are similar to kick stands since they use friction on a flat edged component that touches the ground when the motorcycle approaches a stationary position. This leads to premature wearing out of such a component and may lead to sparking that is dangerous near fuel driven motorcycles.
Su, U.S. Pat. No. 5,886,349 proposed an automated motorcycle stand that is activated by a manual switch. The stand comprises two specially designed rods vertically mounted to the bottom of a motorcycle. The rods are activated from a retracted position to an extended position by means of complex gearing that is coupled to in-built electronics. The rods have wheels that touch the ground in the extended position. As discussed above, the need for mechanical gears may lead to mechanical unreliability. The need for a manual switch to activate the stand is a limitation on the automatic nature of the stand.
For the foregoing reasons, there is a need to provide improved automatic balancing stands for supporting motorcycles in an upright position and methods for providing support for a stationary motorcycle in an upright position.
SUMMARY OF THE INVENTION
Accordingly, it is an object of this invention to provide improved automatic balancing stands to support stationary motorcycles in an upright position.
It is a further object of this invention to provide improved automatic balancing stands to support stationary motorcycles in an upright position that require minimal mechanical components.
It is a still further object of this invention to provide improved automatic balancing stands to support stationary motorcycles in an upright position that are activated by sensors rather than mechanical switches.
It is a still further object of this invention to provide improved automatic balancing stands to support stationary motorcycles in an upright position that use hydraulics.
It is a still further object of this invention to provide a method for supporting a stationary motorcycle in an upright position.

DESCRIPTION OF THE INVENTION
According to FIG. 1, an automatic balancing stand 10 is secured to a portion of a surface of a top frame member 38 and to a portion of a surface of a piston 40 of a motorcycle near a rear wheel 36 of the motorcycle and a pair of slidable members 16, 18 of the automatic balancing stand 10 is in an extended position. The automatic balancing stand 10 comprises a pair of members 12, 14, which are substantially V-shaped. One end of each one of the pair of members 12, 14 is coupled to an end of each one of the pair of slidable members 16, 18. When the slidable member 16, 18 are in an extended position (see FIGS. 1 and 3) the slidable members 16, 18 straddle outside of two lower frame members 42, 44 of the motorcycle. Each one of the slidable members 16, 18 is coupled to an end of one of a pair of joint couplers 46, 48 (see FIGS. 1 and 3) at an opposite end of each one of the slidable members 16, 18. Another end of each one of the joint couplers 46, 48 is coupled to each one of a pair of wheels 28, 30 allowing the automatic balancing stand 10 to smoothly roll on the ground when the slidable members 16, 18 are in an extended position (see FIGS. 1 and 3). A pair of wheel covers 32, 34 (see FIGS. 1 and 2) are coupled to a portion of an external surface of each one of the pair of joint couplers 46, 48 (see FIGS. 1 and 3). The wheel covers 32, 34 are safety protectors from the wheels 28, 30 for a user of the motorcycle and safety protectors for the wheels 28, 30 from flying debris.
Referring further to FIGS. 1-4, each one of the pair of members 12, 14 is a hydraulic cylinder comprising a one-sided hydraulic piston housed internally within each one of the pair of members 12, 14. Another end of each one of the pair of members 12, 14 is coupled to a hydraulic pump assembly 20. The hydraulic pump assembly 20 comprises at least a pump, a valve mechanism and hydraulic fluid to provide hydraulic action for each one of the one-sided hydraulic pistons so that each one of the pair of slidable members 16, 18 may be extended when the pump is activated. The hydraulic pump assembly 20 is further coupled to the pump that is partially enclosed in a housing 22, as well as in the hydraulic pump assembly 20. A motion sensor 24, which is coupled to a power supply 26 of the motorcycle is further coupled to a controller comprising electrical circuitry within the housing 22. The motion sensor 24 signals the controller to activate the pump when the motorcycle slows to a preset speed. The pump moves hydraulic fluid through the valve mechanism against each one of the hydraulic pistons within each one of the members 12, 14 so as to act upon each one of the slidable members 16, 18 extending the slidable members 16, 18. When the motorcycle is stationary, each one of the slidable members 16, 18 is fully extended so that each one of the pair of wheels 28, 30 meets a portion of a road surface providing upright stability for the motorcycle. When the motorcycle moves above a preset speed, the motion sensor 24 signals the controller within the electronic housing 22 stopping the pump and hydraulic fluid drains back through the valve mechanism releasing each one of the hydraulic pistons so that each one of the slidable members 16, 18 is retracted (see FIGS. 2 and 4). When the motorcycle is stationary and an ignition switch for the motorcycle is switched off, the controller within the housing 22 closes the valve mechanism within the hydraulic pump assembly 20 so that hydraulic pressure is maintained in the members 12, 14 and the slidable members 16, 18 remain fully extended. When the ignition switch is turned on, the controller within the housing 22 opens the valve mechanism and turns on the pump within the hydraulic pump assembly 20 so that the slidable members 16, 18 remain fully extended until the motion sensor 24 detects that the preset speed is exceeded causing the controller to turn off the pump in the hydraulic pump assembly 20 fully retracting the slidable members 16, 18 as described above.
FIG. 2 is a partial perspective view of the motorcycle with the automatic balancing stand 10 of FIG. 1 near the rear wheel 36 and with the automatic balancing stand 10 in a retracted position. The wheels 28, 30 straddle outside of the two lower frame members 42, 44 of the motorcycle. All other features of the automatic balancing stand 10 in FIG. 2 are the same as described above.
FIGS. 3 and 4 are perspective views of the automatic balancing stand 10 of FIGS. 1 and 2 in respectively the extended and in the retracted position without the portion of the view of the motorcycle. FIGS. 3 and 4 more clearly show the features of the automatic balancing stand 10 described above.
In summary, the present invention is directed to an automatic balancing stand for a motorcycle. The stand comprises a motion sensor coupled to a controller housed in an housing that signals a pump when the motorcycle changes speed. The housing is coupled to a hydraulic pump assembly comprising at least a pump, valve mechanism and hydraulic fluid. The stand further comprises a pair of members which are each coupled to a slidable member coupled to a wheel. Another end of the pair of members is coupled to the hydraulic pump assembly. The motion sensor signals the controller to activate the pump when the motorcycle slows to a preset speed causing the pump to activate hydraulic pistons within each one of the members extending the slidable members fully when the motorcycle is stationary. The slidable members are retracted when the motorcycle moves above the preset speed.
While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing and other changes in form and details may be made therein without departing from the spirit and scope of the invention. For example, the automatic balancing stand may be coupled to the top frame and the piston in various ways, including brackets or clamps for welding or bolting. The automatic balancing stand may be coupled to other portions of a motorcycle. The automatic balancing stand may be coupled to scooters and bicycles. The motion sensor may be connected to a wheel or to the speed indicator gauge. The motion sensor may be a photocell, a RF sensor, a gyroscope or use a Doppler shift mechanism. The wheel covers may comprise metals or plastics.
