This invention is to provide a kind of sporting toy car for children, which mainly raises children's interest in toys of this type and provides a wholesome physical exercise for children playing with it to promote their growth.
Description
~Z31~i7 The present invention relates to a sportin~ car fo~
children, more particular~y of the twis-tin~ car t~pe.
Most of the current toy cars ~or children are m~de similar to a general automobile or three~wheel car. ~hey are driven ahead by feet pedaLing or by hands. As a result, they cannot provide a balanced development for children's growth since they merely exercise their hands or feet without exercising their main bodies. Furthermore, such dri~ing exercise has made children tired of -the to~vs. This invention is a kind of novelty toy car designed to overcome the above-mentioned w~ak points and can be driven ahead along a wavelike track merel~ by hands oscillating with a child's twisting body.
Such a driving technique certainly will appeal to children's curiosities and is an excellent aide to the growth and development for children due to a complete physical exercise`
in its operation.
This invention is a kind of sporting car provided for entertainment, which has four wheels~ the front ones are fixed on both ends of an axle and may each rotate freely. Also the axle of the two front wheels is fixed on the handle and may rotate about a point when the handle is twisted. The handle is mounted on a car body by means of pivot, and while in driving, it is twisted by means of manual control to make the car body drive ahead along a wavelike track since the front wheels turn from side to side while the handle is twisted. As a result, the child will fully enjoy such entertainment due to complete physical twisting while driving the car.
More specifically, the invention as broadly claimed herein is a toy car which moves in a wavelike pattern due to a driver's ~wisting motion comprising in combination: a fram~, a pair of handles connected to a front portion of the frame through a pivot bolt, a wheeled first axle interconnecting a ~.2~3~367 terminal rearward portion oE the frame, and a wheeled second axl~ interconnecting the pa.ir of handles at an area between -the pivot bolt and -the wheeled first axle whereby rotation o~ the handles rotates the wheeled second axle about the pi~o-t bol-t and thus the car moves in a serpentine manner.
In a preferred form of the invention, the pivot bo~t is affixed to the frame through a bearing, and joint type plates are fastened to a bottom face of the frame and a top face of - the handles around the pivot bolt, and a second bearing separates the joint type plates to provide pi.voting action.
Preferably alsor a transverse bar interconnects the handles and serves as a foot support forward of the pivot bolt and substantially in a same horizontal plane whereby the feet can assist in rotating the handles.
In this preferred embodiment, the frame may be substantially V-shaped and may diverge rearwardly from the pivot bolt, the first wheeled axle being longer than the second wheeled axle and the wheels on the first axle having a greater diameter than the wheels on the second axle. The seat for the driver may be fixed to the frame.
In a further preferred embodiment, the handles are substantially C-shaped when viewed from a side of the car and each has a lower portion which together define a pair of laterally spaced substantially parallel bars flaring and diverging upwardly and outwardly with a concave portion facing the rear of the car, whereby the handles and the foot res~s can provide a turning moment on the second axle about the pivot.
Advantageously, the axles may mount on the frame and handles by sliding onto bifurcated extremities of the frame and of the handles.
A preferred embodiment of the invention will now be described with reference to the appended drawings wherein ~,_ 3 ~ 386~7 Fig. 1 is a top view showing -the construction o~ the car body and the movin~ capability of the handle;
Fig. 2 is a sectional yiew alon~ the dotted line A-~of Fig. 1 showing the details of the car body and wheels;
Fig. 3 is a bottom view showing the further details of the car body and car wheels' Fig. 4 is a front view of the front side of the car body;
Fig. 5 is a side view of a dri~er in the car~ and Fig. 6 is an enlarged view of part B in Fig. 2.
The substantial components of this invention are as follows:
The seat cushion 1 is fastened on frame 8 by means of a screw set 6 and fastener 7. Frame 8 is substantially ~-shaped (as shown in Fig. 3). At the rear end, this frame 8 is con-nected with a rear wheel axle 9 which has rear wheels 4 at both ends. These two rear wheels 4 rotate freely around rear wheel axle 9; and a support 10 is jointed at the front of the frame, which support 10 has a hole for being mounted with handle 2~
Handle 2 is fastened to transverse pole 3 and joint 12. Handle

Fig. 5 is a side view of a dri~er in the car~ and Fig. 6 is an enlarged view of part B in Fig. 2.
The substantial components of this invention are as follows:
The seat cushion 1 is fastened on frame 8 by means of a screw set 6 and fastener 7. Frame 8 is substantially ~-shaped (as shown in Fig. 3). At the rear end, this frame 8 is con-nected with a rear wheel axle 9 which has rear wheels 4 at both ends. These two rear wheels 4 rotate freely around rear wheel axle 9; and a support 10 is jointed at the front of the frame, which support 10 has a hole for being mounted with handle 2~
Handle 2 is fastened to transverse pole 3 and joint 12. Handle
2 mounts under the rame 8 by means of a pivot bolt 13 passing through support 10 and joint 12. Bearings 15 (as shown in Fig. 6) go between handle 2 and frame ~ so that they may turn freely. The distance between handles near handgrips 11 is at a minimum. There is a front wheel axle 14 set at the end of handle 2 close to pivot bolt 13, where there are mounted front wheels 5 at either end of the front wheel axle such that the front wheels rotate freely. The diameters of the front wheels are smaller than that of the rear wheels 4. Front wh~els 5 are se-t near pivot bolt 13 and between the rear wheels.
In operation the structural features mentioned ~bove work as follows:
38~i7 As shown in Fig. 5, a driver is sitting on seat cushion 1 with his feet on transverse pole 3. ~Iands are grabbing onto handle grips 11 to rotate them around to also meet the twisting body. As a result, while hand grips 11 move toward the left, the car body is moving to the left, and the wheelbase from the right front wheel to the right rear wheel is longer~ Similarly while rotating handle grips to~ard the right, the car will move along to the right, and the wheelbase of left front wheel to the lef-t rear wheel are longer and the car body keeps moving toward the right. According to such movement to the right and left in accordance with the driver's twist and the fundamental laws of motion, the car body will go ahead in a wavelike manner.
Having thus described the preferred embodiment of the invention it should be understood that numerous structural modifications and adaptations may be resorted to without - departing from the spirit of the invention.
