DESC:TECHNICAL FIELD
[0001] The present subject matter relates in general to a footpeg assembly for a vehicle, in particular but not exclusively to a pillion footpeg assembly for a two wheeled vehicle.
BACKGROUND
[0002] Conventionally, a two wheeled vehicle is configured for a seating of one or two persons. In two wheeled vehicles such as a scooter type vehicle or a motorcycle type vehicle, a footpeg assembly is provided for safety and comfort of a rider and a pillion passenger. In a scooter type vehicle, the rider may place his feet on a floorboard region but a foot peg is necessity for the pillion passenger. The foot peg assembly for the pillion passenger is usually matched with the vehicle body shape and often stowed away into a recess space when not in use. The placement of the pillion passenger foot peg assembly has to steadily bear weight of the pillion rider in all situations and match the external shape of the vehicle to ensure that desired breadth of the vehicle is not extended.

SUMMARY
[0008] In an aspect of the present invention, a foot peg assembly comprising: foot peg and a mounting member is disclosed. The foot peg being detachably attached to a frame member. The foot peg comprises: a mounting portion, the mounting portion being configured to receive the mounting member. The mounting portion comprises a stepped profile along a longitudinal axis, the vertical axis passes through a centre of the mounting portion and the mounting member. The mounting member includes a shank portion followed by a threaded portion along a longitudinal axis. The mounting member is manufactured as a single piece structure, and a shank portion of the mounting member having a larger diameter than a threaded portion of the mounting member.
[0009] Summary provided above explains the basic features of the present subject matter and does not limit the scope of the invention. The nature and further characteristic features of the present subject matter will be made clearer from the following descriptions made with reference to the accompanying drawings.
DETAILED DESCRIPTION
[00010] Typically, the pillion passenger opens up the footpeg assembly with his/her leg to use, and this process should be as smooth as possible. The operation of the opening and closing of the footpeg is performed by the pillion rider numerous times during usage of vehicle. Therefore, the footpeg assembly should be capable of perform the operation many number of times for several years.
[00011] Generally, the foot peg assembly is mounted on the vehicle body or a side frame on each of a left and right side of the vehicle as a pair of foot peg assembly. The vehicle body is typically made of fiber and the side frame of the vehicle body is generally a side tube. The vehicle body/side tube in such cases receive direct pressure/unwanted stress from the rider. Additional problems may arise due to vehicle vibrations. Due to high vehicle vibrations, numerous parts of the footpeg assembly may loosen up leading to rattling noise, safety risk etc. The footpeg assembly is generally mounted to the vehicle body/side tube of the vehicle. The primary aim of the present invention is to provide a robust and durable footpeg assembly which can withstand heavy weights and a strong downforce from the rider without causing any bending impact on the vehicle body or the side tube. The problem exaggerates when the pillion riders are habited of jumping on the pillion footpeg assembly or standing on single side foot peg while getting on the vehicle. The present invention aims to withstand such continuous downforce from the rider.
[00012] Conventionally, a footpeg of the footpeg assembly is rotated and retracted to a stowed-in position aligning the shape of the vehicle body. The rotation is done around a clevis pin/bolt. In known footpeg assembly, the footpeg is mounted to the frame/body of the vehicle using a spacer, washer and the bolt. However, in such mountings, the number of parts is more and the assembly is complex. Such assembly takes more time for assembly and is prone to get loosen due to high downforce impact and vibrations. The present invention aims to restrict the size of the footpeg and reduce the number of parts for the assembly.
[00013] In a known footpeg assembly, a ball-catch mechanism has been used on two sides of the footpeg. In such known foot pegs, a slot hole is provided on the mounting portion of the foot peg through which a pivot pin passes which connected to a mounting member. The mounting member has two blind holes to accommodate a ball pin in an open state and a close state of the foot peg respectively. Such a known foot peg has two ball catch mechanism on each of two sides of the foot peg. Deployment of such a blind holes and slot hole complicates the assembly of the foot peg and makes the foot peg prone for loose fittings. During high impact or impactful seating of the pillion passenger, such foot peg may break.
[00014] In another known foot peg assembly, a foot peg is secured to the vehicle body frame. The foot peg has an arm portion and a foot rest portion. One end of the arm portion is pivotally secured to the vehicle body frame and the foot rest portion is retracted to a position under a pillion seat when the pillion step is retracted to a retracted position. Such an assembly affects the retraction of the foot peg but such an assembly is more prone to bending or breaking because of poor mounting provisions.
[00015] In another known foot peg assembly, the foot peg includes a mount adapted to be coupled to a motorcycle and a foot pad supported by the mount. The foot pad is selectively adjustable between a first position corresponding with a first damping characteristic and a second position corresponding with a second damping characteristic different than the first damping characteristic. However, such configuration of the pedal assembly does not resolve the problem of loose fittings and delay in assembly and disassembly time. Neither such foot peg assembly provide sufficient strength which can prevent huge vertical load for long duration of time.
