Abstract
A model car has a car chassis having at least three wheels, a steerable wheel and a steering gear, a spring mechanism that stores energy used to steer the steerable wheel, and a coupling/decoupling mechanism arranged between the spring mechanism and the steering gear. The steering gear has an input gear wheel connected to the spring mechanism, an output gear wheel connected to the steerable wheel, and two intermediate gear wheel paths each comprising an intermediate gear wheel providing an connection between the input and output gear wheels on alternative intermediate gear wheel paths, and the input gear wheel is movable by the coupling/decoupling mechanism to mesh with at least two of the intermediate gear wheels.
Claims12
A model car configured to travel on at least two different paths including one path and at least one other path, the model car comprising
- a) a car chassis (1) having at least three wheels (102, 105) rotatably mounted thereto and a tensionable spring mechanism (101) in a rotary connection to at least one drivable wheel (102) of said at least three wheels (102, 105) for driving said at least one drivable wheel (102), wherein the energy stored in said tensionable spring mechanism (101) is used to drive said at least one drivable wheel (102) and to propel said model car standing on a surface,
- b) at least one steerable wheel (105) of said at least three wheels (102, 105) embodied as a steerable wheel articulated in respect to the car chassis (1) about a steering axis (104), wherein articulation of the at least one steerable wheel (105) is effected by means of a steering gear (3),
- c) a deflection mechanism (2) which is operatively connected to the spring mechanism (101) in such a way that part of the energy stored in the tensionable spring mechanism (101) is used to steer the at least one steerable wheel (105) during propulsion of the model car, and
- d) a coupling/decoupling mechanism (217) operable from outside the model car, functionally arranged between the tensionable spring mechanism (101) and the steering gear (3) and configured to switch a steering function of the at least one steerable wheel (105) thereby switching travel of the model car between the at least two different paths, including switching travel of the model car from the one path to the at least one other path, and switching travel of the model car from the at least one other path to the one path, wherein
- the steering gear (3) comprises a plurality of gear wheels including an input gear wheel (210) operatively connected to the spring mechanism (101), an output gear wheel (211) operatively connected to the at least one steerable wheel (105), and two intermediate gear wheel paths each comprising at least one intermediate gear wheel (306, 307;
- 308, 309) providing an operative connection between the input gear wheel (210) and the output gear wheel (211) on alternative intermediate paths, and
- the input gear wheel (210) is movable by means of the coupling/decoupling mechanism (217) in order to selectively mesh with at least two intermediate gear wheels (306, 307;
- 308, 309), including either meshing with a first of an intermediate gear wheel (306) of a first intermediate gear wheel path, or meshing with a second intermediate gear wheel (308) of a second intermediate gear wheel path, or not meshing with any intermediate gear wheel at all.
