Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a self-propelled toy car and a launch pad for such a car, which car is powered by an air stream supplied by the user through a mouthpiece. It has a flywheel inside that is driven to rotate so as to store .

Toy cars have long been popular with young children and have taken many forms over the years.

Some of them are pneumatically powered, some use gyroscope effects, or a combination of both.

U.S. Patent No. 3. No. 1/3,303 discloses the use of balloons to supply air to drive a turbine, which drives a gear train, the gear train being the driving force in contact with the ground of the vehicle. move the wheel. The user connects the inflated and filled balloon to a conduit leading to the turbine.

The force of the air coming out of the balloon decreases rapidly when the balloon deflates.
The balloon itself causes the car to move forward slowly.

U.S. Patent No. 3,650. No. θA7 shows a gyroscopic toy car in which the flywheel is driven to rotate and store kinetic energy to propel the car and maintain gyroscope stability. U.S. Pat. No. 3,6/9, AO9 discloses a self-propelled toy automobile having a flip-table drive wheel driven by a cord wrapped around a spring-supporting axle. US Patent No. 3.7 g 9.34' 0
The specification describes that a toy car having an air-driven flywheel therein is driven to a launch pad at the same time that the flywheel is driven to rotate by a jet of air supplied from a pump in a launch mechanism. A compressed air propelled toy vehicle and launch system is disclosed. When the flywheel is rotating with sufficient kinetic energy, the car is ejected and disengaged from the launch structure as the car moves across the playing surface, propelled by the energy stored in the flywheel. be done. U.S. Pat. Multiple common wheels are relatively heavy to work with and extend laterally outward on opposite sides to rotate the rear wheel in response to the airflow supplied through the nozzle by the user blowing into the nozzle. It has radial wings.

After the wheels start spinning, the car is placed on the playing surface and propels itself until the kinetic energy stored in the flywheel is expended. The flywheel and vanes rotate inside the wheel housing, producing a whistling sound similar to that of an automobile due to the force of the jet.

U.S. Patent No. 1t, 3217. The drawbacks of conventional air turbine-powered toy cars, including the most suitable self-propelled cars shown in OA No. 3, are that this type of toy car is the most fun! ; its use by A-year-old children is limited by the extremely low efficiency of this air turbine. Air turbine devices consisting of a plurality of radially extending blades arranged between seven pairs of circular side plates are not very effective at converting the energy contained in the airflow into kinetic energy, and their conversion efficiency is generally low. Only about 2%.

O20 per second? rkg/crn2(0,tp,s
Considering the limited lung capacity of a five-year-old child, who can only maintain a pressure of , g, even if the breath is broken up into several small breaths, the car can travel far enough to be excited and entertained. If the air-driven flywheel has sufficient rotational speed fit(k
It is impossible to give. Tests have shown that air turbine-powered vehicles are unacceptable for children as young as 4.5 years old unless the air turbine is at least 10% efficient.

To test the toy car disclosed in U.S. Pat. Once the flywheel has sufficient rotational speed and kinetic energy, the car is placed on the playing surface and the car is thus propelled by the friction tires of the flywheel in contact with the playing surface. During the transition time from the user's mouth to the play surface, which may be relatively long given the infant's limited skills, most of the stored energy is expended and transferred to the flywheel, like a The car will only advance a limited distance before the stored energy is expended.

The purpose of this invention is that when a car is released on the playing surface,
It is an object of the present invention to provide an improved toy automobile of the type having a flywheel therein which is used to store kinetic energy to provide self-propulsion to the automobile.

Another object of this invention is to increase the air flow from the mouthpiece received by a person blowing into the mouthpiece, so as to cause the car to travel farther on the playing surface than a conventional car of the same percentage. An object of the present invention is to provide an improved toy automobile characterized in that energy is more effectively converted into kinetic energy.

Yet another object of the invention is to provide an improved toy automobile characterized in that the improved effects can be achieved with a relatively simple and inexpensive construction.

Another object of the present invention is to provide a launch pad provided in the car body with a launch pad so that a person can blow into the launch pad for the purpose of making a single sound rotation. A spring-loaded granger is used to release the car from the launch pad, leading to a spout that opens into a rotating flywheel, and for a hostage start that moves the car forward before the rotating flywheel touches the playing surface. An object of the present invention is to provide an improved launch device for a toy car.

The foregoing objects and other objects of this invention are: a car body for moving on a playing surface; This is accomplished in an improved self-propelled toy vehicle having at least three supporting wheels.

A plurality of blades are provided on both sides of the relatively heavy driving wheel in order to turn the driving wheel in response to the air flow that follows the nozzle provided on the body. The outer end of the nozzle is designed to obtain human breath either directly or through a mouthpiece that cooperates with a nozzle provided on an attached firing device. Air is directed into the vane channels to turn a wheel that acts as a flywheel, storing kinetic energy to propel the car on the playing surface. Each pair of vanes is closed by a driving wheel and a circular outer plate having a plurality of holes, each hole communicating with a recess defined by an adjacent vane, the adjacent vanes being closed on either side of the driving wheel. The direction of the airflow hitting the blade is changed so that the air exits from the hole in the plate in cooperation with the inclined surface of the plate, thereby improving the conversion efficiency of energy in the airflow into kinetic energy.

The vehicle may be used alone or with a launch pad that increases the vehicle's running speed and range. The launch pad includes a member for removably supporting the vehicle with driving wheels separated from the support surface for free rotation, and a member for removably supporting the vehicle with driving wheels separated from the support surface for free rotation, and a member for removably supporting the vehicle for initial forward movement before the driving wheels contact the high traction surface of the launch pad. It has a member to convey the information. The launch pad and vehicle allow the user to easily place his or her mouth to blow into the outer end of the mouthpiece provided at the rear end of the launch pad, and then easily release the vehicle. It consists of a handheld device that can be placed on a playing surface for firing. The inner end of the nozzle receives a nozzle installed in the car.

Referring to the drawings in detail, FIG. 1 depicts an improved self-propelled toy automobile constructed in accordance with features of the present invention.

The vehicle is designated by the reference IO and has an elongated streamlined hollow bodywork preferably made of molded high-density plastic material. In addition, this car body 12
has an upper plate /Qi that slopes forward and downward,
A raised windproof part /Af is provided at the rear end of the upper plate. The upper plate /44 has a rectangular opening ig> behind the windbreak part /6 which extends sufficiently to the rear end 20 of the vehicle 10. Vehicle body/2 has l pairs of side plates 22, 21I and rear plate 2.
6 as an integral part. The underside of the vehicle body 7.2 is open for receiving the chassis, designated 2g in FIG. The Jassy-g consists of a rectangular frame 30, preferably made of molded plastic material.

In addition, this frame 30 has a screw receiver formed on the axis in the longitudinal direction of this frame 30.
It also has a pair of rearwardly projecting tabs 300.30Df as shown in FIG. In order to form an inlet surface that receives the whole mouth and lips of a person so that when the car 10 is operated without a launch pad, air, which is breath, can be blown into the hollow car body 12. A nozzle 32 is attached to the rear end plate 30E of the chassis 2g and protrudes outward. As clearly shown in Figure 3, the vehicle body/U
A rearwardly projecting tab 300.30D extends into and is engaged with a hole provided in the rear plate 2B, Jll, 3A.
And a single screw extending through the hole 30Bf of the front projection 30 and screwed into the boss qO formed inside the upper plate/4? f, the chassis and 2g are maintained in combination with the hollow vehicle body 1.2.

The vehicle body /2 which has been folded has side plates 2.2. ．． 2'l, one of which is designated ulIA in FIG. This shaft is supported by a recess provided in the lower edge of the side plates 22, 2, and these 1ii11 plates, 22. Coq to axis 4
4 is a loose fit and is supported by the front projection 30k of the frame 30 of the chassis g. This front axle lI freely moves in the opposite direction so as not to interfere with the free rotation of the front wheel q2. At the rear end of the vehicle body 12, another pair of single chambers, one of which is indicated by 21IB in FIG.
This rear wheel lI4 does not support the car body/2 except during the initial acceleration when it is attached to the launch pad, so it is provided only to make the car 10f look like the real thing and does not rotate. For this purpose, it is simply attached to the vehicle body 12 with studs or other fasteners (not shown).

A relatively heavy flywheel-like driving wheel Sθ is provided at the rear of the vehicle in front of the rear wheel q6.
O has a rubber friction tire S which is fitted into a groove 5ti in the center of its outer circumferential surface in order to contact the floor on which a car is placed or other gaming surface in a running direction. This dynamic SO is relatively heavy or dense and is preferably made from nickel plated brass. this@@! ;0 is rotating at a relatively high speed and when the car lθ is placed on the playing surface and released, the driving wheel SO acts as a flywheel that stores the kinetic energy used to propel the car lθ. Driving wheel 5
The 0 is preferably made from brass rod on a lathe and, when actually machined, does not need to be balanced to work well in a toy car. No. 5, 71g
As shown in the figure, the driving wheel or flywheel SO has parallel sides extending inward from its outer periphery! rOA,! ;OB
f, and the slope 500, which terminates at the relatively large hole SOE in the axis, is 500,! It protrudes downward and outward in a conical shape to provide OD'i.

The flywheel SO is driven by a pair of turbine units 5B mounted on either side thereof, each turbine unit 56 consisting of a molded plastic member which is fitted into a hole SOW in the flywheel GO by a force fit. The cylindrical boss 5g is made to fit snugly, the outer edge is bent to receive the propulsion air flow, and the inner edge is formed to match the corresponding contour of the flywheel SO. The blade consists of a plurality of blades 400 extending radially, and an outer circular end plate A with the same number of U-shaped holes as the blades. The holes 6t are formed in the circular end plate 62, and have the same shape as the recesses formed by the parts of the V4 matching blades 60 in the circle formed by the outer peripheral end of the hole 611, and communicate with each of the recesses. are doing. The flywheel 50 and its associated air turbine are mounted within the chassis 2g on a laterally extending shaft 6g, which extends between opposite portions of the frame 30 and at the center of the end plate 62. It extends through all the holes 70 of the same size made in the. Hole 70 is a flywheel/turbine device! rt,
The bearing contact with the IVilB6g is much smaller than the hole &gA at the center of the boss sg, and this contact is only near the end of the hole adjacent to the frame 301i111 of the chassis 8.

As mentioned earlier, Nyasi, 2g is the vehicle body / 2VCklt
When installed, the friction tire 52 is centered entirely on the vertical center plane of the longitudinally extending vehicle body/2.

The flywheel O is the vane 6 of the high-speed air flow from the 3 nozzles.
The collision with 0 causes it to rotate at a very high speed. The front end of the nozzle 32 is located on both sides of the flywheel 50.
Pairs of mutually spaced exits, ? . They are aligned with each turbine to direct airflow toward the curved ends. Air entering the recess formed by a pair of adjacent blades 6θ is connected to the shape of the blades O and the conical slope SO of the flywheel.
Due to the interaction with D, the direction is changed downward and exits through the hole All in the end plate A2. In this way, the turbine 5 makes full use of the well-known principle that energy can be extracted from an air flow simply by changing the direction of the air flow. In this example, the direction is approximately /'
700, achieving an approximately five-fold increase in the efficiency of an air turbine with only curved blades and without the entire device for changing the direction of the air. More specifically, the above-described configuration has a conversion efficiency of only about 70 cm, which is enough for a toddler to generate enough crystal rotation speed to drive the car far enough to maintain the child's interest. It is provided in an inexpensive combination consisting of three easily assembled parts, namely the flywheel 50 and the two turbine devices 5B, which can be precisely assembled by simply pressing the flywheel 50 together.

Such a design is simpler and much cheaper to construct than the automotive turbine and wheel housings shown in US Pat. No. 4.32'l, OA 3.

When air is blown from the nozzle 32 onto the blades AO of the turbine, the turbine blows the flywheel SO and the friction tires! r
- begins to rotate rapidly, and at this time a whistle-like sound similar to the sound of a jet engine is emitted. When sufficient rotational speed and kinetic energy (for older children, blowing in three breaths can give a rotational speed close to 10,000 rpm) is applied to the rotating flywheel Sθ. , the toy car is placed on the playing surface or launched from the aforementioned suitable launching pad, and the friction tires S2 are in contact with the playing surface until the energy of the flywheel Sθ is expended.
causes the vehicle tO to advance in the longitudinal axis direction of the vehicle body l-.

The external shape of this toy car IO is similar to that of a jet powered car, but it can be given a variety of body shapes, and the sounds made by the rotation of the air turbine add even more authenticity to the lifelike toy. The vehicle has a relatively simple construction, is economical to mass produce, and has functional features that maintain the interest of young children.

The child holds the car 10 and blows into the nozzle 3.2 to give a fast rotation to the driving wheels or flywheel SO;
Then, on the game side, there's a car lθ'i'N! However, in order to improve the performance of the vehicle IO, it is preferable to use a launcher in the vehicle 10, a preferred embodiment of which is shown in FIGS. ing.

In preparation for launch, the vehicle lθ is backed into the launch pad 100, and the lower edge of the vehicle tOO rear plate 3θE moves the slanted front end of the hook metal/76 downward, and at the same time the outer surface of the rear plate 3ow moves downward. Push the plunger l into the granger housing lS6 so as to compress the contained spring 75g. During this process, the latch 774 is moved downwards against the movement of the flat springs/gll, tgb, and when the rear plate 30B of the car IO is under full pressure on the upper edge of the latch 77B. , the stake is gold/7A returns to the original, the stake is gold/

At the same time, the inlet end of the nozzle 3.2 of the vehicle 10 enters the front end or outlet end of the outlet/4'θ of the launch pad 100, and since the dimensions of the vehicle 10 and the launch pad lθO are very related to each other, the vehicle 10 When in the latching position, the nozzle 3 of the car 10

In this manner, when air is blown to the air turbine through the entire air pipe consisting of the air outlet /'10 and the nozzle 32, the flywheel 5o and the friction tire tacho begin to rotate by the turbine S6. When sufficient rotational speed and kinetic energy are stored in the rotating flywheel 5 degrees, it is expressed by the pitch of the whistling sound made by the air coming out of the hole AII in the end plate of the turbine S6, and at that time the launch pad lθO is placed on the playing surface, the trigger rod /20 is quickly pressed FVf, so that the lower ends of the tongues //A, //g are flat springs iga,

When the friction tire S2 comes into contact with the corrugated platform /'04, the energy stored in the compressed spring 13g gives the entire vehicle a substantial forward start, and the corrugated surface of the plant platform IOA connects the friction tire S2 with the launch platform tOθ. m f)'t: minimizes and aids in fast starts and maintenance of the kinetic energy stored in the rotating flywheel 50. The vehicle 10 is stable while being propelled by the front wheels engaged with the truck/theta, whose trunk ioq is mounted on a corrugated platform 101. It is slightly beveled from the front end to the front end to allow a smooth and effective transition of the friction tires 52 from the playing surface to the playing surface, so that on the playing surface the car 10 will run the course, and while on the playing surface. , car/θ is stabilized by the gyroscope effect of the flywheel θ rotating at a relatively high speed.

This launch pad 100 is designed and constructed to be used in connection with the above-described toy car lθ, but it is of a width such that the wheels are supported on the track 70g and is connected to the plunger/AO. The latches can also be used to provide forward motion in other types of toy cars that are provided with a rear plate of the type held by the metal t7A.

That is, in order to achieve the forward propulsion provided by the metal 776 and the plunger/AO, there is no need for air force or automatic propulsion to be provided.

The other device that is launched is the plunger/AO.
If the hook opposite to that surface has a plate or similar structure that can be secured to the surface of the hook of metal 77A,
It is important to note that the fitting of Granja t1.0 is effectively achieved only in that case, and this is due to the fact that the vertical distance between Kakehakina/76 and Blankya/6θ is narrow; Due to the small diameter of the plunger and the fact that the tip of the plunger rotates, the spring force is used to launch pencils other than automobiles with wheels, missiles similar to pencils, etc. <f prevents use.

If the hook is not engaged with the object to be fired and the object is not pushed against the spring-forced plunger, the trigger rod will not perform its function. . As a result, in order to emit a noise similar to a pencil or a pencil, a child must grasp the base of the launch pad lθθ with one hand, engage the front end of the plunger ITO with the end of the pencil, and then press the plunger/Aθ gold compression spring. /& Which action must be pushed backwards and then fire the pencil,
Such a procedure is difficult even for adults and it is difficult to achieve a safe firing. Because of the arrangement and interaction between the hook and the plunger iAO, the launch mating is safe if used for its intended purpose, and is useful for those curious about using the launch pad for other purposes. It will hinder the child's attempts.

This invention is based on a toy car and a launch pad for the same.
Although shown in accordance with two illustrative embodiments, it will be appreciated that various modifications to one or both of these may be devised by those skilled in the art without departing from the true spirit and scope of the invention as set forth in the claims. You will understand.
