SAFETY SIDE STAND ASSEMBLY FOR MOTORCYCLES
FIELD OF THE INVENTION
The present invention relates to a safety side stand assembly for a motorcycle and more particularly safety side stand which prevents the starting of the vehicle when side stands unfolded.
OBJECTIVE OF THE INVENTION
It is an object of the invention to provide a reliable system for preventing the
operation of a motorcycle while it is in a dangerous configuration.
It is a further object of the invention to provide a simple and reliable system for preventing operation of a motor-powered, two wheel cycles while its storage stand is in storage position.
It is a more particular object of the invention to provide a simple and reliable safety system for motorcycles which defeats an operating system of the engine until the storage stand is in proper position for safe operation of the cycle.
It is a special object of the system to provide a simple and reliable safety system for motorcycles which defeats the electrical system of the engine whenever the storage stand is not in a safe position for operation of the motor cycle.

BACKGROUND OF THE INVENTION
Motorcycles have gained enormous popularity in the past decade, and accompanying the gain in popularity has been an increase in death and injuries resulting from motorcycle accidents. The purpose of the present invention is to prevent one cause of motorcycle accidents, namely the side stand on the motorcycle being "down" in its supporting position while the motorcycle is being driven.
As most experienced motorcyclists are aware, a side stand can pose a serious threat to the safety of a motorcyclist if it is not in its "up" or stored position while the motorcycle is being driven. The danger to the motorcyclist normally is the greatest when the motorcycle is leaned by the driver to negotiate a turn and the side stand is thereby brought into contact with the ground. The contact between the ground and the side stand while the motorcycle is moving will often cause the motorcycle to jerk or spin, and, in such a situation, a motorcyclist can easily lose control of the motorcycle.
Some side stands have been designed so that if they are down and come into contact with the ground they will be immediately pushed by the ground away into their up position. However, these side stands have not eliminated the danger. Depending on how and where the ground contacts the side stand, the condition of the ground surface, and the construction of the side stand, the stand may or may not be pushed into the up position. Even if it is pushed into the up position, the momentary contact with the ground is often enough to jerk or otherwise affect the movement of the motorcycle. Even if the movement of the motorcycle is not at all affected, the driver can be startled upon hearing the side stand strike the ground and thereby be dangerously distracted.

Insofar as is known, there is no prior art teaching the installation of a safety side stand on a motorcycle to alert a driver if the stand is down.
In order to overcome the above said drawbacks associated with prior arts, thus the present invention developed. The present invention prevents the starting of the motorcycle without folding up the side stand. It is a usual that some people forget to fold the side stand and riding the vehicle. The accident happened because the motorcycle side-stand had not been pushed back after riding on the vehicle. It struck against an obstruction on the ground while the vehicle was moving. This habits leads to even fatal accident as well as damage of the vehicle and also causes to injure third party and their property damage. This safety arrangement prevents the starting of the vehicle with side stand unfolded and it will be started only if the side stand is folded. The main advantage of the present invention is Prevention of loss of life and property damage by negligence. This stand can be unfolded instead of operating ignition key, this increase the life of ignition key and switch. It will aware the people when they are in tension.
SUMMARY OF THE INVENTION
In accordance with the present invention, a safety side stand for a motorcycle is provided for alerting the driver if the stand has not been moved to its up position. The device includes a switch mechanically connected to the frame and electrically connected with the ignition and so that an alert can be given whenever the ignition is off and the stand is down.
Preferably, the device further includes a position responsive cut off switch electrically connected to the ignition. Thus in the preferred embodiment, the side stand switch are electrically connected to the ignition switch of the motorcycle.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Fig. 1, 2 and 3 illustrate a motorcycle having a tubular frame assembly 1, a side stand 4, an ignition switch 9, a rear wheel , all mounted on a rear shock absorber pivotally mounted to the frame 1.
Side stand 4 is attached by a bolt 6 to a stand bracket 3 on a lower portion of the frame assembly 1 and is rotatable about the axis of the bolt 6 from a down position for supporting the motorcycle, as is illustrated in FIGS. 1 and 2. The movement of the side stand 4 from its down position to its up position is aided by a side stand spring 7 connected at one end to a lug 8 on the side stand 4 and at its other end to any suitable location on the underside of the motorcycle. Because of the connection of spring 7 to the side stand 4, the positions and movement of the spring 7 will generally follow and correspond to the positions and movement of the side stand 4.
It is to be understood that the illustrated motorcycle is typical of a motorcycle with which this invention may be used. Parts of the motorcycle are shown in simplified form and parts are omitted. In general, this invention may be used with all motorcycles having a stand which should be moved to an up position for safe operation. Thus for purposes of this invention, the construction and location of the

illustrated parts described above are important and for this reason are described or illustrated in greater detail.
As shown in FIG. 1 & 2 the safety device of this invention includes a spring-biased side stand cut off switch 9 mounted on switch bracket to hold securely to the underside of the frame assembly. The cut off switch 9 may be one of any of a variety of commercially available spring-biased switches and, for example, may be
a switch of the type used for motorcycle brake lights. In the illustrated embodiment, the switch 9 is normally close.
With reference to FIG. 3, the illustrated switch 4 includes positive and negatively charged contact plate 15. Prior attempts have included the use of weakened springs for holding the side stand in its lowered position, thereby attempting to minimize the interference of the side stand with safety cut off switch 9. In order to ensure that side stand 4 interface with the safety cut off switch 9 the slatted hole 10 and adjustable nut 11 are provided and switch terminal 13 to link between ignition circuit and ground . The two contact points 15 one is negative and another one is negative provided to ensure the ignition circuit. The push button 17 also provided with spring 16 to release the contact point 15 and contact plate 14.
Side stands on some motorcycles may not have a spring in the same location as side stand spring. In such case the link could be connected to the side stand itself by a clamp or other suitable fastener.
With reference to FIG. 4, one contact of the cut off switch 9 are connected in electrical series by a wire. The other contact of the cut off switch is a ground connection which, as conventional, may be made to the motorcycle frame. A simplified diagram of the usual switch operating circuitry is included in FIG. 4. The switch 9 is connected by a conductor to one positive terminal of ignition switch and the other terminal of switch is connected which its negative terminal

has grounded to the frame. In another preferred embodiments magneto-type ignition system, the cut off switch preferably is a normally closed switch which grounds the magneto and which is opened by engagement by the stopper plate of side stand when the side stand is raised to the operating position of the vehicle.
