Description

March 1, 1966 F. w. BLANCHARD REMOTELY CONTROLLED TOY VEHICLE Filed Feb. 13, 1964 INVENTOR. f70/4D W 5074 1/76 United States Patent 3,237,343 REMOTELY CONTROLLED TOY VEHICLE Floyd W. Blanchard, 2334 Loma Vista Place, Los Angeles, Calif. 90039 Filed Feb. 13, 1964, Ser. No. 344,636 9 Claims. (CI. 4695) This invention relates to a toy vehicle, and more particularly to a remotely controlled toy vehicle.
While remotely controlled toy vehicles are presently available, some of them have the disadvantages that they have a comparatively high first cost, are rather complicated and diflicult to operate and maintain, and are somewhat limited in their range of operation.
In view of the foregoing factors and conditions characteristic of remotely controlled toy vehicles, it is a primary object of the present invention to provide a new and improved toy vehicle not subject to the disadvantages enumerated above and having inexpensive remotely controlled means especially designed for propelling and steering a toy vehicle efliciently, safely and expeditiously.
Another object of the present invention is to provide a remotely controlled toy amphibious vehicle.
Still another object of the present invention is to provide a toy vehicle which is controlled and propelled by hydraulic pressure means.
A further object of the present invention is to provide an inexpensive toy vehicle adapted to be connected to a conventional garden hose to supply water under pressure thereto which propels and steers the vehicle.
In accordance with the present invention, a toy vehicle is provided in the form of a small racing car or the like which has a body portion with a water-tight bottom wall so that the vehicle is adapted to float in a body of water. The vehicle includes a fixed rear axle on which rear wheels are rotatably mounted.
The front wheels of the vehicle are rotatably mounted on a bolster which is pivotally connected intermediate the wheels to the 'front of the vehicle. A nozzle is affixed to the bolster adjacent each wheel. The nozzles are directed rearwardly and downwardly and are connected by a flexible conduit to a source of water under pressure. When the nozzles are subjected to an equal pressure, the vehicle will be propelled forwardly due to water jets issuing from the nozzles. A valve is connected to each flexible conduit so that the flow of water to a particular nozzle can be interrupted at the will of the operator of the vehicle. When the flow of water is interrupted to one of the nozzles while water under pressure continues to issue from the other nozzle, a lever arm is created between the pressurized nozzle and the pivot point for the bolster creating the necessary moment to swing the bolster about the pivot point and turn the front wheels of the vehicle.
The water jets will also propel the vehicle through a body of water and the course of the vehicle in the water may be controlled by manipulating the valves.
In a modification of the toy vehicle, expanding pressure chambers are provided as boosters to increase the turning force on the bolster, particularly at slow speeds or when the vehicle is stationary.
The features of the present invention which are believed to be novel are set forth with particularity in the appended claims. The present invention, both as to its organization and manner of operation, together with further objects and advantages thereof, may best be understood by reference to the following description, taken in connection with the accompanying drawings in which like reference characters refer to like elements in the several views.
In the drawings:
FIGURE 1 is a perspective view of a toy vehicle of the present invention;
FIGURE 2 is a cross-sectional view, on a reduced scale, of the vehicle of FIGURE 1;
FIGURE 3 is a bottom view, on a reduced scale and with parts broken away to show internal construction, of the vehicle of FIGURE 1;
FIGURE 4 is an enlarged cross-sectional view taken along line 44 of FIGURE 3;
FIGURE 5 is a bottom view of the vehicle of FIGURE 1 showing a modified control mechanism; and
FIGURE 6 is a partial, cross-sectional view taken along line 66 of FIGURE 5.
Referring again to the drawings, the toy vehicle constituting a presently preferred embodiment of the invention, generally designated 10, includes a hollow body portion 12 having a wall means 14 shaped to form a hood 16, a cockpit 18 and a tail section 20.
The body 12 has an open bottom 22 defined by an encompassing flange 24 which merges into a shoulder 26. The open bottom 22 may be closed by a bottom wall 28 which is preferably sealed to the shoulder 26 forming a water-tight chamber 30 inside the body portion 12. The chamber 30 imparts buoyancy to the vehicle 10 so that it will float, if desired.
The rear portion of the flange 24 has diametrically opposed notches 32 in which a rear axle 34 is mounted. A rear wheel 36 is rotatably mounted on each end of the axle 34.
The front portion of the flange 24 is provided with diametrically opposed arcuate slots 38 in which the ends 39 of a bolster 40 are mounted. The bolster 40 includes a somewhat triangularly shaped portion 42 which is pro vided with an aperture 44 in its apex 46. The bolster 40 is pivotally connected to the body 12 by a pin 48 which engages the aperture 44 and is retained on the pin 48 by a nut means 50 having resilient fingers 52 which grip the pin 48. The pin 48 is preferably formed integrally with the bottom wall 28 so that it will form a liquidtight connection therewith. A front wheel 54 is rotatably mounted on each end 39 of bolster 40.
The vehicle 10 is propelled and steered by hydraulic jet means which includes a nozzle or jet 56 formed in a block 58. The block 58 is affixed to the bolster 40 adjacent each front wheeel 54 in such a manner that the nozzle 56 points rearwardly and downwardly with respect to the vehicle 10. Hydraulic fluid, such as water, may be supplied to the jets 56 through flexible conduits 60 which are connected to the jets 56 by nipples 62. Flow of fluid through each of the flexible conduits 60 is controlled by a valve 62' which is mounted in each conduit 60 intermediate its ends. Each valve 62' may be operated by a push button 64 in such a manner that flow of fluid through an associated conduit 60 is immediately interrupted by depressing the button 64. The conduits 60 may be connected to a suitable supply of water under pressure up stream of the vehicle 10 by connecting them to a garden hose, not shown. The conduits 60 preferably are brought upwardly through a hollow boss 65 provided in cockpit 18 and are held above the vehicle 10 by a support rod 66. It has been found that such an arrangement makes the vehicle 10 easier to handle than would be the case if the conduits 60 were brought out through the tail section 20 by reducing their drag resistance against the ground as the vehicle moves and by enabling the vehicle to pivot freely in a turn.
Referring now to FIGURES 5 and 6, a vehicle 10a is shown which is identical with the vehicle 10 except that expanding pressure chamber means in the form of flexible bladders 68 are connected in the flexible conduits 60 adjacent the bolster 40a. The bladders 68 are caged within a recess 70 in bottom wall 28a by a pivot arm 72 on bolster 40, depending members 74 on bottom wall 28a and a cover 76. When pressure is reduced-on one nozzle 56, it is also reduced in an associated bladder 68 so that it collapses. The other bladder 68 expands to exert a force against pivot arm 72. Thus, two turning moments act to turn the bolster 40a, i.e., one by the pressurized nozzle 56 and one by the pressurized bladder 68.
Referring again to FIGURES l4, in use, the flexible conduit 66 may be connected to a garden hose, not shown, upstream of the vehicle 10. With both valves 62 open, Water may be admitted to the nozzles 56 so that the water will issue from the nozzles 56 in the form of a jet which propels the vehicle 10 forwardly. Should it be desired to turn the vehicle 10 to the left, as viewed in FIGURE 1, the button 64 associated with the left front wheel 54 of vehicle 10 may be depressed interrupting the flow of water to its associated nozzle 56. Water issuing from the other nozzle 56 will create a moment about the pin 48 through a lever arm defined by the length of the bolster 40 from the pin 48 to the pressurized nozzle 56. The vehicle 10 may be turned to the right in like manner by depressing the button 64 associated with the right front wheel 54.
The modification shown in FIGURES 5 and 6 is useful in turning the vehicle 143a when it is stationary or at slow speeds Where greater turning forces are required than when the vehicle 10a is moving at ordinary speed.
Of course, it will be obvious to those skilled in the art that the expanding pressure chamber means may be employed as the sole steering means. In this event, the nozzles 56 do not necessarily have to be mounted on the bolster 40a.
Since the vehicles 10 and 10a are buoyant, they function as amphibious vehicles so that they may be driven from a roadway into a body of water. Jets issuing from the nozzle 56 propel the vehicles through the water and the vehicles may be turned within a body of water in the same manner that they are steered on land by actuating the valves 62.
While the particular toy vehicles herein shown and described in detail are fully capable of attaining the objects and providing the advantages hereinbefore stated, it is to understood that they are merely illustrative of the presently preferred embodiments of the invention and that no limitations are intended to the details of construction or design herein shown other than as defined in the appended claims.
