Description

SURFBOARD AND RIDER TOY
This invention relates to a toy.
More particularly, the invention relates to a surfboard and rider toy which is arranged so that it is capable of riding a wave.
It is known in the art to produce toy surfboards and riders but generally speaking these cannot reliably be used to ride a wave.
The object of the present invention is to provide a novel surfboard and rider toy which is reliably capable of riding a wave.
According to the present invention there is provided a surfboard and rider toy which is capable of riding a wave, said toy including a buoyant board having a length L said board having front and rear ends and top and bottom surfaces, said top and bottom surfaces being curved upwardly at least adjacent to the front and rear ends, a rider means for mounting the rider on the top surface of the board above or rearwardly relative to the centre of gravity of the board.
Preferably the board has a length L.
Preferably the board has a width which is in the range .25L to .4L and most preferably .3L.
Preferably a forward part of the board has a radius of curvature in the range 1.2L to 1.5L and most preferably 1.37L.
Preferably the rearward part of the board has a radius of curvature in the range 4 to
6 times L, and most preferably 5.5L. Preferably the average density of the board is in the range 0.4 to 0.5gm/cm3 and most preferably .46gm/cm3.
Preferably the weight of the board is in the range 100 to 150gm and most preferably 120gm.
Preferably the weight of the rider is 0.3 to 0.4 times the weight of the board and preferably 0.36 times the weight of the board.
Preferably the weight of the rider is 45gm.
Preferably the height of the rider is .3L to .45L and preferably .4L.
Preferably the centre of gravity of the board is .45L to .48L from the rear end of the board and preferably .47L from the rear end of the board.
Preferably the centre of gravity of the rider is .15L to .25L above the top surface of the board and preferably .2L.
The invention will now be more fully described with reference to the accompanying drawings, in which:
FIGURE 1 is a perspective view from the rear of the surfboard and rider toy;
FIGURE 2 is a plan view of the toy;
FIGURE 3 is a side view of the board; FIGURE 4 is a schematic view showing the orientation of the fins;
FIGURE 5 is a side view of the lateral fins;
FIGURE 6 is a side view of the centre fin;
FIGURE 7 is a schematic view which shows cross sections through the board at different places along its length. The drawings show a surfboard and rider toy 2 comprising a surfboard 4 and rider 6 attached thereto. In the preferred embodiment of the invention, the board 4 is moulded separately from the rider 6 and is fixed thereto by means of plastic pins 8 which pass through the feet 10 of the rider and are received within sockets (not shown) moulded into the top surface 12 of the board.
The board 4 is preferably provided with a pair of lateral fins 14 and 16 and a central fin 18. The fins 14 and 16 are preferably inclined inwardly by an angle A as shown in Figure 7. The angle A is in the range 3° to 10° and preferably 5°. The fins 14 and 16 are also preferably inclined outwardly relative to a normal from the bottom surface 36 of the board at an angle B. The angle B is in the range 7° to 15° and preferably 10°. The outer faces 20 and 22 of the fins 14 and 16 are foil shaped whereas the inner faces 24 and 26 are flat. The centre fin 18 has a foil shape on both sides. The board 4 has a pointed forward end 28 and rounded rear end 30. The lateral sides 32 and 34 are rounded. As seen in Figure 7, the radius of curvature of the rounded sides 32 and 34 is smaller adjacent to the bottom surface 36 compared to the radius of curvature adjacent to the top surface 12.
The board 4 is preferably moulded from rigid plastics material. Preferably the board 4 has an average density in the range 0.4 to 0.5gm/cm3 and most preferably the average density is 0.46gm/cm3.
In order that the board 4 has sufficient stiffness it preferably comprises a relatively thin walled hollow structure. This can be accomplished by moulding the board 4 in two pieces and then joining them together by known techniques such as solvent bonding, ultrasonics or the like. Alternatively, the board can be injection moulded using a known technique for injecting an inert gas such as nitrogen during the moulding process in order to form the hollow body. These techniques are known in other fields and therefore need not be described. The preferred material for moulding the board is low density polyethylene having a specific gravity of 0.91.
In the preferred form of the invention, the fins 14, 16 and 18 are separately moulded from the board and mounted in slots (not shown) formed in the bottom 36 of the board. In the illustrated arrangement, the rear end 30 of the board has a minimum radius of curvature of about 25mm. In the preferred form of the invention, the board 4 has a length L and usually L will be in the range 250mm to 400mm. In the preferred form of the invention the length L is 306mm and the width is normally in the range .25L to .4L and preferably .3L. In the illustrated arrangement the width is 90mm. As is apparent from Figure 3, in side view, the forward and rear ends of the board curve upwardly. Preferably a forward part of the board has a radius of curvature in the range 1.2L to 1.5L and most preferably 1.37L. The radius of curvature of the forward part 40 of the board is about 420mm. Preferably the rearward part of the board has a radius of curvature in the range 4 to 6 times L, and most preferably 5.5L. Preferably further the radius of curvature of the rear part 42 of the board has a radius of curvature of about 1670mm.
The fins 14 and 16 are preferably separated by a distance in the range of .15L to .25L and preferably .18L.
Preferably, the centre of gravity 44 of the board is located in the range .45L to .48L from the rear 30 of the board. Preferably the centre of gravity 44 is .47L from the rear of the board.
Preferably the rider 6 is located so that its feet 10 are located either side of the centre of gravity 44, as shown in Figure 2. The position of the rider, however, can be adjusted so that different performance characteristics can be obtained. By moving the rider further rearwardly it has been found to be more stable on larger waves.
The rider 6 preferably has a height which is about .3L to .45L. In the preferred form of the invention the height is about .4L.
Preferably the weight of the board 4 is in the range 100 grams to 150 grams. Usually a weight of about 125 grams is typical for a board having a length of 306mm. The weight of the rider is preferably about .3 to .4 times the weight of the board. In the preferred arrangement, the weight of the rider is .36 times the weight of the board, typically about 45 grams.
The rider is preferably moulded from flexible plastics material which is such that it can be bent readily by a user. In this way the centre of gravity of the rider can be shifted from a centre position to the left, right, forward or rear so as to give different performance and turning characteristics.
The rider 6 is also preferably moulded so as to have a relatively low centre of gravity. Thus can be achieved by moulding the feet and lower legs thicker than the upper part of the torso, head and arms. Preferably, the centre of gravity of the rider is in the range .15L to .25L and preferably about .2L above the top surface 12 of the board.
A prototype of the invention has been tested and has been found to ride a wave reliably. In use of the device the user places the toy in an upright position on the crest of a shore wave of a height typically less than lm. The toy will ride the wave in an upright position for a considerable distance. The toy can be made to turn left or right by bending the rider 6 so as to shift its centre of gravity to the left or right.
Many modifications will be apparent to those skilled in the art without departing from the spirit and scope of the invention.
