Specification

FIELD OF INVENTION
The present invention relates to a fender for the rear wheel of a two-wheeled motor vehicle.
BACKGROUND TO THE INVENTION
There are many arrangements of protecting from the splashing of water by the wheels in vehicles to prevent the water from being splashed on other vehicles or pedestrians. Also, the water thrown out by the wheel may enter the internal parts of the vehicle causing them to malfunction. However, none of these may be as efficient as that desired in terms of diverting the water away from the sensitive parts of the engine and towards the road surface. It is attempted in the present invention to achieve a fender, which diverts water away from vehicle parts particularly, electrical parts.
It is possible to provide an intermediate mud guard for the wheel, but to avoid the water entry, it has to extend below fender which may not be desirable from the point of aesthetics.
The known fenders may be provided with ribs on underside for strengthening. Motorcycles may be provided with fenders comprising skirts arranged along its length to prevent splashing of water from the wheels, enhance vehicle life and passenger safety. However, water is still splashed from the top end of the fender where the skirts may not be useful and the splashed water enters the vehicle's internal parts, possibly damaging the components and potentially posing a safety hazard owing to water entry into electrical components.
In another aspect of the present invention, the electrical components are enclosed into a compartment that is openable only on one side and situated away from the direction of splashing water.

PRIOR ART
It is a known problem that vehicles/water splashes when speeding on a rainy road. This leads to dangerous situation of blinding the adjacent driver and simultaneously damaging the own vehicle. Many attempts have been made to reduce the amount of spray created by the rotating wheels and to divert the water towards the road surface. However, most of them are complicated and bulky e.g. US 4,660,846; US 4,921,276 and US 6,719,318.
US 4,660,846 relates more particularly to a spray shield or splash guard that is adapted to be suspended in generally vertical orientation and disposed rearwardly of the vehicles' wheels to obstruct the spray of rain, dust, snow and rocks which may be thrown upwardly and rearwardly or laterally by the wheel.
US 4,921,276 relates more particularly to a fender which is adapted to be suspended over each of the wheels, or each of the sets of wheels, on each side of an automotive vehicle, and particularly large vehicles such as trucks and trailers to restrict the spray of rain, dust, snow and rocks which may be thrown upwardly and rearwardly or laterally by such wheels.
In US 6,719,318 trailer hitch cover assembly for a motor vehicle includes a hitch insert having an aperture extending longitudinally there through to fit over a hitch tube of a trailer hitch on a motor vehicle, and a rotatable door covering the aperture. The trailer hitch cover assembly also includes a top cover plate mounted to the hitch insert and a front cover plate mounted to the hitch insert and having an aperture extending there through aligned with the hitch tube of the trailer hitch.
In general, a housing acts as an enclosure for the cables which is not attempted in the prior art vehicle due to various reasons. The prior art suffers from one more disadvantage from the wires being distributed across the body of the vehicle thereby being prone to accidents and damages.

OBJECTS OF THE INVENTION
The first object of the invention is to direct the water splashed by a vehicle wheel away from sensitive parts of the motor vehicle particularly the electrical parts and minimize the entry of water onto the engine surface.
The second object of the invention is to provide an enclosed housing for accommodating sensitive electrical components such as wiring harness and circuitry.

A plurality of skirts are provided on the inside surface of the fender.
Preferably, at least one enclosed storage space is mounted on the vehicle frame
near an upper end of the fender.
Preferably, the skirts are spaced from each other.
Preferably, the skirts are substantially parallel.
Preferably, at least one skirt is positioned to deflect the water splashed from the
wheel away from the fender.
Preferably, the skirts extend transversely across the width of the fender.
Preferably, the enclosed storage space has at least one side which is openable.
Preferably, the said openable side opens away from the fender.
Preferably, the inside surface of the storage space is accessible from the said
openable side.
Preferably, components of the vehicle sensitive to water are housed within the said
storage space.
In a second aspect, the invention provides a vehicle body frame, structure for a two

DESCRIPTION OF THE DRAWINGS
It will be convenient to further describe the invention with reference to the accompanying drawings which illustrate preferred embodiments of the fender of the present invention. Other embodiments are possible, and consequently, the particularity of the accompanying drawings is not to be understood as superseding the generality of the preceding description of the invention.
The structure of the present invention has on underside of the fender a plurality of skirts disposed therein, such that the water from the road is divided off and guided by plurality of skirts back towards the road surface.
The structure of the present invention is to provide a location for electrical parts such as HT coil, CDl, Starter motor relay etc., which is substantially closed from all sides and which is attached from upper end to the cross number of the chassis and to the lower end the fender is attached.
The facilitate assembly of electrical parts in such a location the frontal side is kept open which subsequently closed by assembly of another part.

DESCRIPTION OF PREFERRED EMBODIMENTS:
The description herein covered relates to one of the preferred embodiments illustrated in Figures 1, 3, 4A, 4B and 4C wherein the underside of the fender 1 has an additional set of skirts 2 disposed along its length, the said each skirts 2 disposed transversely across the width of the fender.
The working of the invention is described herein below. The water hitting the skirts 2 positioned on the underside gets divided amongst the skirts and handled by a plurality of skirts creating thereby a situation wherein the splashing water is smoothly

led back towards the road surface as illustrated in Figure 5. This is in contrast to an arrangement in prior art where the splashed water is led inward of the fender towards engine parts.
Because of the plurality of flexible skirts 2 in the central portion and the rigidity of the fender also improved there is a reduction in the splashing of water sidewards and upwards, thereby causing least damage to the own vehicle parts.
Because there is a plurality of skirts each skirt having one edge fixed to the planar surface of the fender and the second free end, and each skirt being independent it is possible to split and select the number and size of the skirts thereby for this reason efficiency can be improved.
It is envisaged in the preferred embodiment that the plurality of the skirts are all identical to one other though this may not be essential in all cases. Each of the skirt may have a different shape and size from the other skirts disposed on the fender.
It is envisaged in the preferred embodiment that the inter-space between the skirts is uniform but the invention also covers non uniform distance between the skirts.
The skirts disposed on the underside of the fender and within the outer edges of the fender provide a possibility of retrofitting the fenders as per the invention on a vehicle on road.
In a second aspect of the invention, housing has been provided as an enclosure within which all electrical parts can be mounted without any contact with splashing water.
The waterproof enclosure has an housing (3) having six members (4-9) covering and adjacent to each other to form an enclosed rectangular box with an interior cavity formed within illustrated in Figures 6, 7, 8 and 9. The bottom plate member is fixed on the vehicle frame 15 for holding the body housing upright. One surface of the

body provided with a removable openable portion and said surface (10) is recessed to allow the cables to run through. Since the openable surface portion is provided facing away from the mudguard 16 of the vehicle it resists catching splashing water from the road surface. The material of the body housing is preferably electrically nonconductive plastic.
The most significant feature of the enclosure is that it is sealed on five surfaces and only the sixth surface is openable. In one of the embodiment of the invention as depicted Figure 7, one of the surfaces of the enclosure may be closed by rear portion of storage box 17, hence eliminating need for separate openable surface.
In such an arrangement all electrical connections are typically enclosed in one area facing one direction such that the access to the connectors and cables is restricted, controlled and protected.
By enclosing the electrical connections in one area and directing the leads out of the enclosure in only one direction, the safety of the enclosure increases as it is sealed on all its other sides and thereby displays an improved water proof and safety characteristics.
Previously the wires run along the frame and or scattered onto different areas along the body. Even though they served the purpose the system was not particularly safe or well designed. Here the attempt has been made to have and enclosure for this application with the necessary safety feature demanded in the application.
Currently in the prior art the free wiring allow access to the connection terminals while the terminals are energized and also when they are wet due to splashing road water, thereby creating a risk for somebody who may accidentally touch the exposed terminals.

Therefore, there exists in this field a need for safer design to manage the wiring and significantly reduce the risk of exposure of these wires to splashing water from the road surface by shielding them.
The device of the housing and the method of mounting has several features which provide several advantageous over traditional devices and methods.
In one embodiment the housing 3 is attached onto the body frame near the raised top end of the mudguard. This aids in preventing the inadvertent splashing of road water accessing the wiring. The skirts 2 in the fenders prevent the splashing to a very large extent and the balance portion of the water which gets splashed are at least diverted away from the vehicle back towards the road surface.
Together the modified fender and the electrical enclosure prevent the water splash and protect the electrical components running within the vehicle.
The fender and the housing are adapted to be secured the rear of the vehicle. Accordingly as illustrated in the accompanying drawings and as described above, a fender has been achieved which facilitates smooth driving avoiding water entry to the vehicle parts.
The modification of the fender is simple and easy as the external configuration of the fender is not altered, does not disturb the structural arrangement for fitting the fender onto the vehicle thereby facilitating the continuous use of mounting mechanism of the fender onto the vehicle adopted and used in prior art.
The objects, scope and description of the present invention has been given herein. However, it should be understood that the drawings and descriptions are indicative and illustrative for the purpose of explanation thereby including all variations and modifications within the spirit and scope of the invention to the extend as apparent to those skilled in the art covered in the application.
