Abstract

A hand-propelled toy airplane, locomotive or other wheeled vehicle for pre-school children having a handle making it possible for a player to push the vehicle along a surface. The vehicle is provided with one or more lights whose bulbs are connected to a battery supply through a handle switch that is actuated only when the player grasps the handle to turn on the lights. Operatively coupled to the axle of a wheel set is an interrupter switch connected in series with the handle switch, the circuit arrangement being such that when the handle switch is actuated, at least one light goes one, and when the vehicle is pushed along the surface, the actuated interrupter switch then causes the lights to turn on intermittently to produce a blinking effect at a rate depending on how fast the vehicle is being propelled. When the handle switch is released by the player, the battery supply is disconnected from the bulbs, so that no power is drained from the supply when the toy is not in use.

Claims

1. A hand-propelled toy vehicle having a body and provided with a battery power supply, a set of wheels mounted on an axle and a U-shaped handle whose ends are secured to the body, the handle to be grasped by a player to propel the vehicle along a playing surface, said vehicle comprising:

(a) a trigger-actuated, spring loaded, normally open switch mounted on an inner surface of the handle, the switch being closed by the player when grasping the handle and in doing so squeezing the trigger;

(b) an interrupter switch operatively coupled to the axle, whereby as the axle rotates, this switch is periodically opened and closed at a rate that depends on the speed of rotation;

(c) at least first and second light bulbs disposed in the vehicle; and

(d) circuit means connecting the first bulb through the handle switch in parallel with the interrupter switch to said supply and also connecting said second bulb through the handle switch in series with the interrupter switch to said supply, whereby when a player actuates the handle switch and the interrupter switch is then closed but the vehicle is not yet being propelled, the first bulb is then turned on, and when the vehicle is thereafter propelled by the handle, the second bulb is turned on intermittently to produce a blinking light action, neither bulb being turned on when the handle is not grasped by the player.

2. A toy vehicle as set forth in claim 1, wherein said interrupter switch has a movable contact that is operatively coupled to the axle by means of a cam mounted on the axle which, as the axle turns, causes the movable contact to periodically engage a fixed contact to close the switch.

3. A toy vehicle as set forth in claim 2, wherein said interrupter switch includes a pair of fixed contacts on either side of the movable contact, one fixed contact being connected to said first bulb and the other fixed contact to a second bulb, whereby as the axle turns, the first and second bulbs are alternately turned on.

4. A toy vehicle as set forth in claim 3, wherein said vehicle is in an airplane format having wings, and said first and second bulbs are mounted at the tips of the wings.

5. A toy vehicle as set forth in claim 4, wherein said airplane has a translucent fuselage section behind which is mounted a third bulb connected in parallel with the first bulb.

6. A toy vehicle as set forth in claim 1, wherein said handle switch is formed by a pair of normally parallel, flat metal springs, one of which is deflected by the squeezed trigger into engagement with the other spring.

7. A toy vehicle as set forth in claim 1, wherein said vehicle body is in a locomotive format having a headlight opening associated with one of said light bulbs.

8. A toy vehicle as set forth in claim 2, wherein the fixed contact is mounted on an insulating plate of flexible material which is contoured to define a tine, said tine engaging the teeth of a gear mounted on the axle adjacent the cam to deflect the tine periodically as the axle rotates to produce an engine noise.

9. A toy vehicle as set forth in claim 1, further including a third bulb and wherein said axle is formed of conductive metal and is provided with an insulating cam segment and said interrupter switch comprises first and second spring contacts disposed on opposite sides of the axle whereby as the axle rotates the segment thereon is alternately interposed between the axle and one of the contacts, the other contact then electrically engaging the axle, the first contact being connected through the second bulb and the handle switch to one terminal of the supply, the second contact being connected through the third bulb and the handle switch to said one terminal of the supply whose other terminal is connected to a third spring contact which permanently engages the axle, whereby when the handle switch is closed said first bulb is then engaged, and when the vehicle is thereafter propelled, the second and third bulbs are alternately energized.
