Rear fender for a Scooter type motorcycle

Field of invention

The present invention relates to a "Rear fender for a scooter type motorcycle" and more particularly to a rear fender made of resin for increasing the stiffness

Background of the invention

The present invention relates to rear fender for scooter type motorcycles. The rear fender assembly in a scooter type motorcycle includes a front-half rear fender subassembly, arranged above the scooter type motorcycle rear wheel and below a seat assembly, and a rear-half rear fender subassembly extending rearward from the seat assembly. The rear fender basically address three important functions namely as a protection against mud and alike substances, as a licence plate holder and holder for illumination for the license plate. Sticky materials such as mud may adhere to the smooth outer tire surface, while smooth loose objects such as stones can become temporarily embedded in the tread grooves as the tire rolls over the ground. These materials can be ejected from the surface of the tire at high velocity as the tire imparts kinetic energy to the attached objects. For a vehicle moving forward, the top of the tire is rotates upward and forward, and can throw objects into the air at other vehicles or pedestrians in front of the vehicle. The rear fender effectively avoids this. In the contemporary scooter type motorcycles the rear fender is mounted only for the purpose above. However in case of scooters provided with fuel tank on the rear most part of the frame, there is no such protection from the mud, splash and equivalents originating from the riding surface. Hence the objective of the present invention to provide a rear fender for a scooter type motorcycle that overcomes the above problem.

Brief description of the invention

The rear fender comprises a set of mounting holes on the main curb separating the upper and lower portion of the rear fender and a profile having extended corrugations spaced along the upper part of the fender to form crests and troughs. The corrugations act as ribs to provide extra strength and stiffness. Moreover an extended mounting support at the frontal portion of the upper part of the fender is provided with a support base and an extended bracket so that the slot imbibes itself with the frame to provide extra support and strength to the rear fender. Also, an extra space for utility such as fuel tank mounting is created over a C shaped arcade by raising the curb of the upper part so that a subtle portion is carved out for extra storage.

Detailed description of the invention

Figure 1 illustrates the side view of a concerned scooter type motorcycle wherein all the embodiments viz. left side cover mounting, right side cover mounting, rear fuel tank cover and an under cowl.

Scooter-type vehicles, or scooters, include a frame assembly, which usually supports the body of a scooter, along with front and rear wheels. A frame assembly for a scooter-type vehicle comprises of at least one front wheel, at least one rear wheel and a vehicle body.

Typically, a frame structure 101 for a scooter type motorcycle comprises a main frame and may also have a sub-frame. The sub-frame is attached to the mainframe using appropriate fastening members. All the other components such as the body panels, the engine 102, the electrical units are mounted on the main frame and the sub frame either directly or by means of brackets and fastening members.

The frame assembly includes a head tube, which supports a front wheel suspension assembly 103 of the vehicle. An upper frame extends from the head tube to a rearward end of the vehicle body. A swing arm 104 is pivotally supported by the upper frame and supports a rear wheel of the vehicle. The frame assembly may include a lower frame removeably coupled to the upper frame and defining a space 107 there between.

The sub-frame preferably supports at least one component of the scooter-type vehicle in the space, such as a fuel tank, for example.

Typically, front 103 and rear 104 suspension assemblies are operatively positioned between the front and rear wheels and the frame assembly. The front suspension assembly commonly is a telescopic fork arrangement, while the rear suspension assembly is a swing type arrangement. In a scooter, the rear suspension swing arm typically supports a power unit 102, which is configured to drive the rear wheel of the scooter.

The power unit 102, is coupled along with a transmission assembly 108, such as a drive shaft, drive belt, or chain and sprocket assembly.

The frame assembly 101 of a scooter-type vehicle is an elongated structure, which typically extends from a forward end to a rearward end of the scooter. A scooter frame assembly generally is convex in shape, as viewed from a side elevational view. A handlebar assembly 105 and a seat assembly 106 are supported at opposing ends of the frame assembly and a generally open area is defined there between. The rear fender 109 is placed on the rearward end of the scooter

Accordingly, the open area between the handlebar assembly and the seat assembly allows the scooter to be easily straddled, or mounted, as opposed to a typical motorcycle, wherein a motorcycle fuel tank occupies the space between the handlebar assembly and the seat assembly. Such an arrangement may be referred to as a "step-through" frame assembly. Generally, a scooter frame assembly is constructed of a welded-up assembly of individual tubular members.

Typically, a central portion of the frame assembly includes a pair of upper tubes, and a pair of lower tubes. The individual pairs of upper and lower rails usually are aligned with one another in a vertical direction and spaced from one another in a lateral direction, with the pair of upper rails being spaced above the pair of lower rails.

Figure 2 and Figure 3 illustrates the rear fender that is the subject matter of the present invention. The scope of the present invention is a rear fender 109 of a scooter type motorcycle comprising a set of mounting holes 201 on the main curb separating the upper 202 and lower portion 203 of the rear fender 109 and a profile having extending corrugations 204 spaced along the upper part of the fender to form crests and troughs.

Mounting holes 201 are provided so that the rear fender is latched on to the frame 101.

The corrugations 204 act as ribs to provide extra strength and stiffness. Moreover an extended mounting support 205 at the frontal portion of the upper part 202 of the fender is provided with a support base and an extended bracket 205 so that the slot 206 imbibes itself with the frame 101 to provide extra support and strength to the rear fender 109.

Also, an extra space for utility such as fuel tank mounting is created over a C shaped arcade 301 by raising the curb of the upper part so that a subtle portion is carved out for extra storage. Mostly the space 301 can be utilised for fuel tank support and carving out an aesthetically smooth harbourage. The said rear fender can either be made of metal sheets or fibre incorporating metal inserts.
