Holder for handgrip device

Field of invention

This invention is related to "Holder for a handgrip device" and more particularly related a retrofittable bracket for providing a handgrip for the pillion rider of a motorcycle.

Background of the invention

In most of the known type of motorcycles, handgrip device is provided behind the pillion rider. The said handgrip device is permanently mounted on the frame structure behind the seat. This device provides a secure hold to the pillion rider when the vehicle is accelerating, decelerating or moving at steady high speeds. Since the said device is mounted behind the pillion seating area, it is uncomfortable for the pillion rider to access the said device located behind his back and can cause fatigue during the vehicle movement. In case of ladies sitting on one side of the vehicle, the said device is accessible only to one hand causing further safety related issues especially during sudden braking of the vehicle. However this is overcome in some motorcycles having two separate seats for the rider and pillion. In these vehicles, an inverted U type bracket is mounted onto the frame structure between the riders' seat and pillion seat in addition to the handgrip device provided behind the pillion seat. This arrangement for such vehicles makes the pillion rider to hold the said U type bracket since it is in front of the pillion rider. Even if the pillion sits on the side, there is a secure hold for each of the hands of the pillion rider. In some two-wheelers provided with a single continuous seat, to be shared by rider and pillion, have a strap attached to the middle of the seat. The ends of the strap being riveted or fastened on either side of the seat base which holds the seat. Such arrangement is effective only if the seat base is made of sheet metal since the strap should not tear off while pulling. Considering the cost effectiveness and manufacturing feasibility, the contemporary motorcycles are having only plastic seat bases. In such vehicles having a continuous seat with plastic seat base, there is a need to provide a safe bracket for handgrip device for the pillion.

Hence the objective of the invention is to provide a bracket for a handgrip device for a motorcycle having a continuous seat.

Another objective of the present invention is to provide a bracket for a handgrip device that can be fitted as an accessory in the field and still meeting the safety requirement.

Another objective of the present invention is to provide a bracket for a handgrip device that can be used for multi utility functions for holding or suspending articles.

Brief description of the invention

The present invention consists of a bracket or a seat belt holder securely held by known means on either side of the seat behind the rider. The said bracket consists of an L shaped plate having a longer leg wider than a shorter leg. The outer most intersection of legs is blended with a chamfer more or less equal to 45 deg. A hole is provided on the shorter leg located beyond the width of the longer leg. The angle between the shorter & longer is more or less perpendicular. Two projecting lugs are formed integrally away from the inner surface of the bottom most point of the shorter leg. At least two slots of known shapes running along the longer leg are provided as provision for a cable or belt to pass through. The said bracket grip is clamped to the top end of the shock absorber located behind the rider seat on either side of the frame. In another embodiment, the said bracket is mounted directly onto an integral part of the frame member. In both the above embodiments the hole is used for clamping purposes. In both the above embodiments the projected lugs facilitates anti rotation. The slots, which help in adjusting the length of the cable or belt and securing the cable /belt in position, are aligned at an ergonomically convenient angle to the profile of the seat contour. The edges of the bracket are given a smooth radius and the said bracket is made of a suitable material stiffness in the range of 4000 N/mm to 64000 N/mm in the direction of load application i.e. cable or belt pulling direction.

Detailed description

A motorcycle comprises of a frame 103, front fork 104 attached to a pivot tube of the vehicle frame 103, a front wheel 105 attached to these front forks 104, a handle bar 106 connected to the front forks 104, a fuel tank 107 attached so as to straddle an upper part of the vehicle frame 103, a seat 102 attached to the upper rear portion of the vehicle frame 103, an engine unit 108 attached to the lower front section of the vehicle frame 103, a swing arm 109 attached to a lower rear section of the vehicle frame 103, suspended by a rear shock absorber 110 from the vehicle frame 103 and a rear wheel 111 attached to a rear end of swing arm 109. The intake system of the engine comprises of a carburettor, intake duct and an air cleaner. The exhaust system of the engine comprises of exhaust pipe and a muffler. A holder 101 also attached to the rear portion of the frame that acts as a handgrip device for the pillion rider. The motorcycle is also provided with a side cover 113 for covering a side section of the vehicle frame, a seat cover for covering a rear section of the vehicle frame below the seat, a front fender 114 for covering an upper part of the front wheel, and a rear fender 115 for covering an upper part of the rear wheel 111.

The disclosure provides the description of a retrofittable hand-gripping device 201 for a two-wheeler for multi utility functions. The present invention comprises of a bracket 210 securely held by clamping and/or other fixing means 203 on both the sides of the seat 102 behind the rider. The bracket 210 is nearly L shaped wherein the width of the longer leg is more than that of the shorter leg of the said bracket. The outermost intersection of legs is melded having a chamfer of around 45 degrees. The innermost intersection is nearly perpendicular. A hole 204 is provided on the shorter leg as shown in the diagram, located beyond the width of the longer leg 205 of the bracket 210. Moreover, a pair of extrapolative conducts 206 is positioned such that they are integrally away from the inner surface of the bottom of the shorter leg 207 as shown in the diagram. Slots 208 are provided in the longer end 205 for making provisions for materials such as cables, belt, etc. to pass through. This bracket 210 could be mounted in either of the formats wherein the bracket 210 is clamped to the top end of the rear shock absorber 110 that is located behind the rider seat on both the sides of the frame 103. Alternatively, the said embodiment could be directly mounted on the frame 103 themselves. The main aim of these mounting is to provide facilities for anti rotation in case of stress and pressure. The brackets 210 are arranged in such a manner so that it opposes rotation and remains rigidly attached during riding conditions. The bracket 210 is aligned economically so that it gives convenience in order to fix belt 209 and other attachments as required. The edges of the bracket 210 are given a smooth radius and the said bracket 210 is made of a suitable material stiffness in the range of 4000 N/mm to 64000 N/mm in the direction of load application i.e. cable or belt 209 pulling direction. Figure 1 illustrates left side perspective view of a motorcycle with respect to prior art. Here 101 illustrate the hand-gripping device attached to the frame situated behind the rear seat 102.
