Definitions
- the present invention pertains generally to the field of toy vehicles and tracks or roadways upon which they travel and more particularly to a novel technique to accelerate unpowered vehicles along a track or road-Way.
- Toy unpowered vehicles are well known in the art. Generally, these vehicles, for example, are either adapted to be pushed along a horizontal surface such as a boor and on the ground or they are designed to follow a track or roadway and caused to accelerate therealong through the force of gravity by elevating a portion of the roadway.
- a horizontal surface such as a boor and on the ground
- they are designed to follow a track or roadway and caused to accelerate therealong through the force of gravity by elevating a portion of the roadway.
- the roadway In the second example, the roadway must be provided with an elevated portion and after each run, the vehicle must be manually replaced at'the top of the elevated roadway.
- Another object of the present invention is to provide an unpowered vehicle toy that does not require a portion of a roadway upon which the vehicle travels to be elevated and which provides an acceleration force on the vehicle independently of the force of gravity.
- Yet another object of the invention is to provide an unpowered vehicle toy 'wherein vehicles of varying sizes and weights may be accelerated along a track or roadway.
- stationary pressure means is disposed in a position to contact unpowered toy vehicles on a roadway.
- propulsion means including a rotating drum is disposed adjacent the roadway opposite the toy vehicles from the stationary pressure means for engaging the vehicles and providing thereto a force equal but opposite from the stationary pressure means and also an accelerating force in the direction of travel of the vehicles along the roadway.
- FIG. 1 is a perspective view of a single rotating drum toy vehicle acceleration mechanism constructed according to the present invention
- FIG. 2 is a cross-sectional view taken along line 1212 of FIG. 1.
- FIG. 3 illustrates another embodiment of the invention wherein a single rotating drum acts along the side of a vehicle to be accelerated
- FIG. 4 is an elevational view of an embodiment of the invention wherein a single rotating drum acts on an upper surface of a toy vehicle;
- FIG. 5 illustrates yet another embodiment of the invention similar to the embodiment shown in FIG. 4 but including means for allowing the rotating drum to follow the irregular upper contour of the toy vehicle to be accelerated.
- a first embodiment of the invention is shown generally designated as a single drum vehicle propulsion unit 301.
- This unit comprises a roadway portion 303 having an inner side wall 305 and an outer side wall 307 and a pair of elevating members 309 supporting the roadway portion 303.
- Attached to the side walls 305 and 307 is a tunnel arrangement 311 including side members 313 and a roof member 315.
- the roadway portion 303 is provided with a rectangular aperture 317 approximately centrally disposed between the side walls.
- the dimensions of the aperture 317 are large enough to just accept a portion of a rotating drum 319 protruding therethrough as it rotates in the direction indicated by an arrow 321.
- the drum 319 includes a pair of outer resilient tire portions 323 and is mounted on a motor shaft 325 of the electric motor 327. In order to energize the electric motor, it may be connected by means of electric wire 329 to a source of electricity (not shown). Alternatively, the drum 319 may be provided with a single tire portion.
- an unpowered toy vehicle 331 which is to be accelerated along the roadway 303 in the direction indicated by an arrow 333, makes simultaneous contact at its bottom portion 335 with the resilient tire portion 323 and at its top portion 337 with a resilient pressure exerting surface 339 of a stationary pressure plate 341.
- the pressure plate 341 is mounted on the tunnel arrangement 311 and extends from the roof member 315 to position over the axis of rotation of the drum 319.
- the function of the resilient pressure plate 341 is to exert an equal and opposite vertical force on the top portion 337 of the vehicle 331 as is being exerted by the tire portion 323 on the bottom portion 335 of the vehicle, to allow it to remain in a stable condition while being provided with a horizontal force in the direction 333.
- the resilient pressure plate may be fabricated from any suitable synthetic or metallic material such as for example, beryllium copper.
- An unpowered toy vehicle may also be provided with an acceleration force in the desired direction by a single rotating drum acting against a stationary pressure plate in a horizontal positioning arrangement 401 as shown in FIG. 3.
- a vehicle 403, having a first side 405 and a second side 407, is to be accelerated in the direction indicated by an arrow 409 along a roadway section 411 including a flat bottom surface 413, an inner wall 415 and an outer wall 417.
- an electric motor driven drum 419 having a resilient outer circumference 421 and rotating in the direction as shown by arrow 423.
- a resilient pressure exerting surface 427 of a stationary pressure plate 429 is also disposed alongside the roadway section, directly opposite to the axis of rotation 425 of the drum 419.
- This arrangement provides simultaneous and opposite forces perpendicular to the direction 409 of travel of the vehicle 403 since the resilient surface 421 engages the vehicles first side 405 at the same time the resilient pressure exerting surface 427 engages the vehicles second side 407.
- This system effectively cancels any lateral resultant force on the vehicle while providing an accelerating force along the roadway in the direction of the arrow 409.
- the stationary pressure arrangement described above need not always take the form of a pressure-exerting resilient plate.
- a single drum propulsion unit 501 may be utilized.
- a motor driven rotating drum 503, rotating in a direction as indicated by arrow 505, may be supported above a roadway section 507 so as to have a resilient outer surface 509 contact an upper portion 511 of an unpowered toy vehicle 513 supported by wheels 515 and moving in the direction of arrow 517.
- the arrangement described with respect to FIG. 4 utilizes the roadway 507 acting on the vehicle 513 through its wheels 515, to provide the necessary upward vertical force which cancels the downward vertical force component exerted by the pressure of the resilient portion 509 on the vehicles upper portion 511.
- the desired horizontal component provided by the rotation of the drum 503 is present to provide the desired acceleration.
- the rotating drum may be mounted in a fixed position to contact only the upper portion of the vehicle to be accelerated as shown in the embodiment of FIG. 4, or the drum may be mounted in such a manner that it will follow the upper contour of the vehicle, as is provided by the acceleration unit 601 illustrated in FIG. 5.
- an unpowered toy vehicle 603 having an irregular upper contour 605 and wheel 607 is to be accelerated in the direction of arrow 609 along a roadway 611.
- a rotating drum 613 including a resilient outer contacting surface 615.
- the drum 613 is mounted in a fixed relationship on an axle 617 that extends through a bearing aperture (not shown) adjacent an outer end 619 of a pivotally mounted arm 621.
- the axle 617 also carries a drum drive pulley 623 to which an outer drive belt 625 is also coupled to a first intermediate pulley 627 held by an intermediate axle 629 which passes through a bearing aperture (not shown) in a fixed pedestal 631 standing alongside the roadway 611.
- the intermediate axle 629 also carries a second intermediate pulley 633 that is caused to rotate by the movement of a motor drive belt 635 coupled to an electric motor (not shown).
- the diameter of each of the various pulleys is not critical and is governed by speed and power consideration well known to any engineer of ordinary skill in the mechanical art.
- the arm 621 is pivoted at its inner end 637, about the intermediate axle 629 to thus allow the drum freedom of movement in the path of an arc segment as indicated by arrow 639.
- This freedom of movement is limited, however, in its downward direction by a mechanical limit stop member 641 extending upward from the pedestal 631.
- this acceleration unit 601 performs like the unit 501 described in detail relative to FIG. 4.
- the invention provides a new and useful toy that propels unpowered toy vehicles of varying weights and sizes in a stable condition along a track or roadway.
