(54) Title:
IMPACT FENDER
(57) Abstract:
The kung kong fender are shock absorbers made from metal bars and springs. One bar above lies the other and is welded on the vehicle. The one below protrudes beyond the vehicle and is held horizontally by asmall metal bars welded on the bar above . On collission , the protruding bar is pushed inward to the vehicle. It compresses springs held between the two bars and also pushes levers that are pivoted on bar above and on vehicles wheels so that the whole stands on the small wheels on the levers.The mall wheels allow the vehicle to roll off from the point of the impact. The clutch is pushed in, the gear is also pushed to the neutral position so that the vehicles wheels can turn freely to the force of the impact.
 
KUNG KONG FENDERS
These are basically Front and Rear Shock absorbers. They are for protecting a vehicle from damage and its occupants from injury or death in the event of a collision.
They are made of four pairs of metal bars, coil springs, 5.    leaf springs and small wheels.
The four pairs of metal bars are almost similar, therefore one pair is used to describe all the others. b,c,d can be
used to denote parts corresponding to the parts being described.
10. Two pairs of the metal bars are at the front part of the vehicle each pair at either side of it. The other two pairs
are at the rear and also each at either side of the vehicle.
Every pair has two main metal bars i.e Bar (1) and Bar (2). 15. Bar (1) is above Bar (2).
Bar (1) is either bolted or welded on the underside of the vehicle's body. An L-shaped flat bar (18) is welded on Bar (1) at the front end as shown in figure 1. The bar is for holding bar (2) in place without hindering its movement.
20. Metal pierce (7) which is for holding coil spring (8), and has an aperture for allowing bar (2) to pass through, is welded on bar (1). A metal stopper 19 for stopping bar (2) from moving beyond a certain point is also welded on bar {1)
25. Levers (31),(34) and (42) are pivoted on bar (1). One end of lever (31) is attached in a free movement manner to brakes lever (32). Likewise one end of lever (34) is also attached to clutch lever (33). Clamps (38) & {40) are made
in such a way that they slide along bar (1).
 
2
One end of bar (2) protrudes beyond the end of bar (1) and also the front of the vehicle for the front pair, and the back of the vehicle for the rear pair. The protruding part of bar (2) is long enough to be bent upwards at some point
5.    well away from the vehicle's body. Two metal bars (3) and
(4)    are bolted on the bent bars at the front while bars
(5)    and {6) are bolted on the bent bars at the rear.
Metal plate (9) is welded on bar (2) at the point where one
end of coil spring (8) reaches. The coil spring is held in
10. place by metal plate (9) on bar (2) and metal plate (7) on bar (1). The coil spring is not welded on any side. Bar (2) passes through the spring and the aperture in m e t a 1
plate (7).
The similarities on the front and rear pairs of the metal
15. bars cease there, but similarities on the front pairs continue and the similarities on the rear pairs continue. So one front pair will be described and one rear pair will be described below.
FRONT PAIR
20. Three small metal pieces (10), (11) and (20) are welded on bar (2). Two metal levers (12) and (13) have small wheels (14) and (15) at one end of each lever. The levers (12) and (13) are pivoted on the vehicles wheels' axles by metal tubes (16) and (16b) that allow the levers free movement.
25. Return springs (17a) is fixed on one end on bar (1) and the other end on lever (12).The small wheels (14) and (15) on the levers lie beyond the diameter of the vehicle's wheels welded on bar {2).
A metal rod (45) which is bent in a such a way that when it 30. is pushed it pushes one end of the leaf-spring to minimise the shock.
 
3
One front pair on the right hand side is different from the one on the left in that it houses more small metal pieces and levers.Small metal pieces (29), (30), (35), (3e), (43) and (45a) are welded on bar (2) on the right side. An
5.    adjustable flat bar (44) is bolted on piece (29).
If a head-on collision occurs, both bar (2a) and (b) would be pushed inwards to the vehicle. Metal plate (9) would push the coil spring and the small metal pieces (10) and (11). Metal (10) and (11) would push levers (12) and (13) e.t.c
10. to a vertical position subject to the force of the impact. Small metal piece (20) and metal stopper (19) would stop bars (2) and levers (12) and (13) e.t.c from moving beyond a vertical position. Levers (12? and (13) e.t.c standing at a vertical position would force the vehicle and its wheels
15. off the ground since the combined diameter of the levers and the small wheels is greater than that of the vehicles wheels. The vehicle would then roll off on the small wheels from the point of impact. This would reduce or eliminate the fatal collision force. Even without a coil spring, the
20. levers (12) and (13) etc would still be pushed to a vertical position by bar (2). But the spring helps in returning bar (2)to its original position.
When bar (2) is pushed in, metal pieces welded on it push levers (31), (34),(42) and clamp (38).Clamp (40) is pushed 25. in by lever (42).
The brakes lever (32) is stopped from going in beyond a certain point by bar (44). If the driver happens to have fully applied the brakes,bar (44) pushes back the brakes lever to the desired position. By controlling the brakes
30. applications, the movement of the vehicle's wheels is also controlled.
The clutch lever (33) is pushed in by lever (34) and plate
(35),It releases the gears temporalily and temporalily
allows the vehicle's wheels free movement. The wheels free
35. movement mean that the vehicle and its occupants would not have to absorb all the collusion force since the vehicle can move off from the point of impact.
 
4
When the clamps (38) and (40) are pushed towards each other
by plate (36) and lever (42), they push the gear rod {39)
from any of the gear's positions (46a & b) to the neatral
5.    position (47) thereby releasing the gears until they are
again physically engaged. By releasing the gears, the vehicle's wheels gain free movement again but for alonger time. This adds a guarantee of safty to a vehicle's occupants.
10. REAR PAIR
Metal pieces (21a) and (21b) are welded on the underside of the vehicle. A leaf spring assembly (22) is placed on the metal pieces (21a) and b by laying the springs on the flat bars (24a) and (24b). The flat bars (24a) and b are welded
15. on metal pieces (21a) and (b) and the metal holder (25). A center bolt joins the leaves to a round metal bar (23). Bar (23) can move to and fro in its holder (25). The holder is welded on the under side of the vehicle. A V-shaped metal bar (26) is welded at its apex on bat (23). Metal pieces
20        (27a) and (27b) axe welded on the open ends of the v-shaped
metal.
Light collision force on the rear bar (2) would be neutralised by coil spring {8) before reaching the leaf springs since there is a gap between the end of bar (2) and
25. plate (27). But on a strong force, bar (2) would push both the coil spring and the metal (27) thereby, pushing the V-shaped bar (26), bar (23) and the leaf spring (22). Since collision forces at the rear axe not too severe, it is possible that the force can be neutralised by springs
30. without any harm coming to the vehicle or the occupants.
