Definitions
- the present invention relates to a toy vehicle, which when pushed momentarily puts into motion a high inertia element that returns the energy stored therein at the end of the external thrust.
- the vehicle has such an arrangement of the high inertia element that friction losses in it are reduced, while at the same time giving the vehicle improved self-aligning characteristics with respect to known embodiments.
- patent document US 800,741 describes a toy consisting of a hollow figure representing a dance couple in whose interior a captive ball is arranged. In this way it is achieved that the figure can freely rotate on itself and move in all directions when it is supported on a plane that is inclined in one direction or another at will.
- the high degree of freedom offered by the spherical shape of the ball is used, but it is not aware of the possibilities that a heavy ball would offer.
- the toy is not intended to be pushed by hand, which is confirmed by his drawings, which represents a crystal ball, not metal.
- Document US 4,156,986 describes a small toy vehicle, very economical, intended to be incorporated as a gift in cereal packages, for which it is made by injection in a plastic material, with a high inertia disk that rotates around a cross axis while rolling on the support surface. In this way it is achieved that, once the vehicle has been started by manual thrust, the movement continues for a longer time than if the vehicle did not present the high inertia rotating disk.
- the applicant's experience with the vehicle just described has shown that, surprisingly, when the ratio of the inertia of the ball to the vehicle's weight is considerably increased, the conditions of self-alignment thereof change.
- the inertia of the ball is not very high with respect to the weight of the vehicle, there is an undoubted interest in it resting on a circular surface, since this causes a pair of forces that move the front of the vehicle with respect to the center of rotation thereof, which is located at an intermediate point between the rear wheels.
- the explanation is that it is the vehicle (heavier) itself that determines the main trajectory, limiting the ball to exert a lateral reaction on the front of it.
- the main path is determined by the ball and it is the vehicle that rotates around it, simultaneously moving both its rear and its anterior part.
- the evolution of the vehicle is determined by the position of its resistance center (defined by the result of the frictional forces of its wheels) with respect to the ball of inertia.
- the proposed objective is achieved in the vehicle of the invention through the provision of a captive ball, of considerable inertia with respect to the weight of the vehicle, inside the cavity formed by an upper body and a lower chassis; in such a way that said ball rolls freely on the surface of Toy vehicle support.
- the opening of the vehicle chassis, and through which the ball appears, is straight sided polygonal, which replaces the linear contact of the prior art with one or two point contacts.
- the polygonal opening is arranged in front of the center of resistance of the vehicle, defined as the virtual actuation point of the result of the various friction forces that act on it due to the weight of its wheels on the support plane.
- the center of resistance will be on the intersection of the Rectangle bisectors defined by the contact points of the wheels with respect to the bearing surface. Otherwise, the center of resistance will move towards the wheels that support a greater percentage of the vehicle's weight or, in general, have greater friction, which can be modified by varying the width and roughness of the same.
- the evaluation of the center of resistance of the vehicle may be carried out by calculation or, preferably, by empirical tests.
- the choice of the distance between the point of contact of the ball with the support surface and the center of the polygonal opening will be made depending on the maneuverability desired for the toy vehicle, so that the characteristics of the same, depending on whether it is a sports car or a transport vehicle, for example.
- Figure 1 shows a plan diagram of the forces acting during self-alignment as it has been shown to occur in vehicles made according to the prior art.
- Figure 2 shows a plan diagram of the forces acting during self-alignment as it has been shown to occur in the vehicle made according to the invention.
- FIG. 3 shows a partial section, in elevation, of the vehicle object of the invention.
- the numerical references correspond to the following parts and elements:
- Figure 1 illustrates the scheme of forces and movement that occur during the self-alignment of a vehicle made according to the prior art.
- the relatively heavy vehicle will determine the main trajectory after the manual impulse.
- the ball of inertia (5), acting on the circular partition (9) generates a resulting force R1 that causes the vehicle a moment M1 that tends to move its front part in the direction of the deflected impulse, causing the vehicle to rotate with respect to a center of rotation 0 which, under these conditions, is located between and next to the rear wheels.
- the movement is considerably abrupt and unnatural, while supposing high friction losses between the inertia ball (5) and the circular partition (9).
- the inertia ball (5) is held captive between an upper body (2) and a chassis (3) in which a polygonal opening (4) is made through which the inertia ball ( 5) it can roll on the support surface (8), but without letting it pass through it when the vehicle (1) is lifted from the support surface (8). See figure 3.
- the inertia ball (5) must be inserted between the upper body (2) and the chassis (3) before joining it by any known means, and the wheels can be mounted rotating on the corresponding wheel axles ( 7), or they may be fixed, merely decorative, forming part of the upper body (2) or the chassis (3), which will significantly reduce the product.
