This invention generally relates to a vehicle, and more particularly, to a spinning vehicle apparatus and assembly.
Although toy vehicles have proven to be extremely successful and long-lasting products, manufacturers are constantly seeking new ways to make the operation of such vehicles more entertaining and amusing. While many toy vehicles are configured to be propelled on wheels in a straight path, some manufacturers have produced toy vehicles capable of performing one or more stunts or tricks. However, many toy vehicles have a predictable path of movement, which may become mundane or less entertaining after multiple uses. Moreover, while certain toy vehicles having spinning capabilities, their spinning behavior is typically limited to a single direction of rotation relative to the support surface on which the vehicle is propelled.
In addition, many toy vehicles have a tendency to flip over when performing tricks or to stop when the vehicle runs into an obstacle in the path of movement. Either of these circumstances requires the operator to manually place the vehicle back to its upright position or move the vehicle away from the obstacle and propel the vehicle again. Such an interruption may frustrate the operator and make the experience less enjoyable. As such, there is room for improvement of toy vehicles with spinning mechanisms.
According to one embodiment of the invention, a vehicle configured to operate on a support surface includes a platform having first and second sides and upper and lower surfaces. The vehicle also includes first and second wheels operatively coupled to the platform and disposed proximate the first side of the platform. The first and second wheels each have a support surface contact patch, and the contact patches lie in a first plane. The vehicle further includes a disk rotatably coupled to the lower surface of the platform. The disk has first and second regions associated with respective first and second sides of the platform and an inner ring. In an embodiment, the disk also has an outer ring. The disk lies in a second plane disposed at an angle to the first plane, such that when the contact patches of the first and second wheels are in contact with the support surface the first region is further away from the support surface than the second region and the inner ring contacts the support surface. In an embodiment, the vehicle further includes a pinion gear configured to engage a rack gear to thereby rotate the disk when the rack gear is pulled.
According to another embodiment of the invention, an assembly includes a vehicle configured to operate on a support surface and a rack gear. The vehicle includes a platform having first and second sides and upper and lower surfaces. The vehicle also includes first and second wheels operatively coupled to the platform and disposed proximate the first side of the platform. The first and second wheels each have a support surface contact patch, the contact patches lying in a first plane. The vehicle further includes a disk rotatably coupled to the lower surface of the platform. The disk has first and second regions associated with respective first and second sides of the platform and an inner ring and an outer ring. The disk lies in a second plane disposed at an angle to the first plane, such that when the contact patches of the first and second wheels are in contact with the support surface the first region is further away from the support surface than the second region and the inner ring contacts the support surface. The vehicle further includes a pinion gear coupled to the disk. The rack gear is configured to engage with the pinion gear to rotate the disk and inner ring to thereby propel the vehicle on the support surface.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and, together with the detailed description of the embodiments given below, serve to explain the principles of the invention.
With reference to
The vehicle 10 may be designed to resemble a skateboard (
The vehicle 10 is configured to be propelled on the support surface 28 in various directions, in a typically unpredictable path, and spun upon different parts of the vehicle 10. A movement path of the vehicle 10 may include straight or arcuate movement, spinning, turning, or even flipping. The vehicle 10 may be propelled by hand, by the rack gear 12, or by another rotation source.
With reference to
The upper and lower surfaces 48, 50 of the platform 14 are generally planar, and the platform 14 lies substantially within the plane 22. The platform 14 may be composed of plastic or another suitable material. When the vehicle 10 is positioned with the contact patches 26 of the wheels 16 on the support surface 28, the plane 22 is disposed at an angle relative to the plane 30 in which the contact patches 26 lie. In this way, the side 40 is distanced further from the support surface 28 than the side 42. As shown in
The platform 14 has an aperture 52 extending vertically through the platform 14 (i.e., extending from the upper surface 48 to the lower surface 50). The aperture 52 generally corresponds in size and shape to pin 54 (described in further detail below).
With continued reference to
The wheels 16, 18 may be designed to resemble skate board wheels. The wheels 16, 18 may be composed of rubber or encircled with rubber o-rings for increased traction with the support surface 28. Increased traction will cause the vehicle 10 to be propelled in a generally straighter path than wheels 16, 18 having less traction.
In an embodiment, axle supports 58 extend from the lower surface 50 of the platform 14 proximate the ends 44, 46 thereof. The axle supports 58 may be coupled to the platform 14 or formed integrally therewith. In the embodiment shown, the lower edge 60 of each axle support 58 is concave, forming an inverted U-shape. In this embodiment, one aperture 62, 64 runs through each wall 66 of the U-shape, and the axle 56 extends between the two apertures 62, 64. The wheels 16, 18 are positioned adjacent outside edges 68, 70 of the axle supports 58. In another embodiment, the lower edge 60 of the axle support 58 may be generally planar, and a single aperture (or tunnel) may run through the entire length of the axle support 58. As shown in

A pin 54 that extends through apertures 52 in the disk 20 and the platform 14 couples the disk 20 to the platform 14 and creates an axis of rotation for the disk 20. The pin 54 and the axis of rotation are substantially perpendicular to the plane 24 and are tilted from vertical by angle 0 (
Unlike most toy vehicles having a disk with a horizontal axis of rotation, the axis of rotation of disk 20 is substantially vertical. The substantially vertical axis of rotation allows for the disk 20 to have a larger diameter than the disk on the horizontal axis of rotation, and the larger diameter offers energy benefits and different movement possibilities than the disk on the horizontal axis of rotation. For example, for a given material, the greater the diameter of the disk 20, the greater the mass of the disk 20. And the greater the mass, the greater the amount of rotational kinetic energy in the rotating disk 20 for a given angular velocity and, thus, the longer the possible duration of propulsion of the vehicle 10. In addition, the substantially vertical axis of rotation offers different movement possibilities for the vehicle 10 than the horizontal axis of rotation.
Based on these same principles, the material of the disk 20 may be selected so as to affect the movement path of the vehicle 10. The disk 20 may be composed of a metal or other material having a substantial mass and may be formed by die cast. The greater the mass of the disk 20 relative to a total mass of the vehicle 10, the longer the duration of propulsion of the vehicle 10.
The disk 20 has regions 80, 82 associated with sides 40, 42 of the platform 14. Because the disk 20 is configured to rotate, “region” does not refer to a fixed portion of the disk 20. Rather, “region” refers to the portion of the disk 20 that is associated with respective sides 40, 42 at any given time. Depending on the design of the platform 14 and the position of the aperture 52 for the pin 54 in the platform 14, the region 82 may extend beyond side 42 without extending beyond side 40. Because the disk 20 is tilted relative to the plane 30 (
The disk 20 includes inner and outer rings 84, 86. In the embodiment shown, the disk 20 has a lower surface 88 and a side surface 90 around a circumference of the disk 20. The outer ring 86 encircles the side surface 90 of the disk 20. The inner ring 84 is coupled to the lower surface 88 of the disk 20. The inner ring 84 is positioned intermediate the outer ring 86 and the pin 54. An angled annular surface 94 lies between the lower surface 88 and the side surface 90.
Due to the positions of the inner and outer rings 84, 86, only one of the inner and outer rings 84, 86 contacts the support surface 28 during the vehicle's 10 typical operations. In other words, when the inner ring 84 contacts the support surface 28, the outer ring 86 does not, and vice versa. Moreover, because the disk 20 is tilted relative to the support surface 28, only a portion of the inner or outer ring 84, 86 corresponding with region 82 of the disk 20 contacts the support surface 28 at a given time. The remainder of the inner or outer ring 84, 86 is distanced from the support surface 28 at that given time. When the inner ring 84 contacts the support surface 28 and the vehicle 10 is propelled on the inner ring 84, the wheels 16, 18 also contact the support surface 28, and the lower surface 50 of the platform 14 faces the support surface 28 (
With reference to
The inner and outer rings 84, 86 may comprise o-rings composed of rubber or another material that provides traction. Alternatively, the inner and outer rings 84, 86 may be formed integrally with the disk 20. The inner and outer rings 84, 86 have generally rounded outer surfaces.

When the rack gear 12 is not used with the vehicle 10, the pinion gear 76 may not be necessary. In alternative embodiments, the vehicle 10 may use an external motor or a rotating source other than the rack gear 12 to effect rotation of the disk 20. Particularly when the rack gear 12 or other rotating source is used, the vehicle 10 should clearly indicate an intended direction of movement of the vehicle 10 or what is the front of the vehicle 10, so that the vehicle 10 will be propelled away from the operator and not accidentally propelled toward the operator.

Depending on the configuration of the shell 120 and whether the vehicle is to be operated with the rack gear 12, it may be necessary for the shell 120 to include cutouts or otherwise be formed so as to provide access for the end 104 of the rack gear 12 to be inserted into the aperture 62 of the axle support 58.
Similar to the skateboard embodiment, the
In addition to movement on or about the inner and outer rings 84, 86 of the disk 20, the size and shape of the vehicle 10 may provide other surfaces upon which the vehicle 10 may spin. For example, the vehicle 10 may sit up on and spin on the back wheels 16, 18 (
In an embodiment, the pin 54 may have a convex or dome-shaped end 130 that extends slightly past and is disposed adjacent the lower surface 88 of the disk 20. The dome-shaped end 130 may correspond to another pin or a tower-like platform (not shown) having an end with a corresponding concave shape. In this way, the vehicle 10 may be positioned on top of the platform such that the dome-shaped end 130 of the pin 54 rests in the convex end of the platform. The pin 54 may then serve as an axle about which the vehicle 10 may spin on top of the platform. Spinning may be effected by hand power or the rack gear 12, for example.
In use, for the assembly 5 including the vehicle 10 and the rack gear 12, the vehicle 10 is positioned on support surface 28 such that a front end of the vehicle 10 faces away from the operator. One hand is placed on one or more sides 40, 42 or a back end (i.e., the end closest to the operator's body) of the vehicle 10. The end 104 of the rack gear 12 is then inserted through the aperture 72 in the axle support 58 at the back of the vehicle 10 such that the teeth 100 of the rack gear 12 mesh with the teeth 98 of the pinion gear 76. The end 104 of the rack gear 12 may be further extended through the aperture 74 in the axle support 58 of the front end 44, such that the handle 106 is positioned proximate the back end of the vehicle 10 and the end 104 of the rack gear 12 extends beyond the front end of the vehicle 10. The handle 106 of the rack gear 12 is then rapidly pulled back toward the operator's body, so as to cause the teeth 100 of the rack gear 12 to spin the pinion gear 76 and the disk 20 as the rack gear 12 is pulled out of the vehicle 10. When the rack gear 12 is pulled out of the vehicle 10, the operator releases his or her hand from the vehicle 10, and the spinning disk 20 propels the vehicle 10 away from the operator as soon as the operator releases his or her hold of the vehicle 10.
Alternatively, in an embodiment in which the vehicle 10 is operated without the rack gear 12, an operator simply uses his or her hand to propel the vehicle 10. Or as another alternative, an external motor or other rotating source may be used to cause rotation of the disk 20 and, thus, propel the vehicle 10.
