Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
105 words
A toy vehicle equipped with a device operated with an electric motor drive for producing engine noises, said device comprising an adjusting means in the form of a slide simulating a gas accelerator pedal mounted in said toy vehicle, an electric motor, and a noise producing device actuated by said motor under control of said pedal, said pedal being operative to change the frequency and the sound volume of the noise produced by said noise producing device, said toy vehicle including a door and means for actuating and stopping said motor operative in response to the closed position of said door to stop said motor.
Claim 2
Dependent Claim
105 words
A toy vehicle equipped with a device operated with an electric motor drive for producing engine noises, said device comprising an adjusting means in the form of a slide simulating a gas accelerator pedal mounted in said toy vehicle, an electric motor, and a noise producing device actuated by said motor under control of said pedal, said pedal being operative to change the frequency and the sound volume of the noise produced by said noise producing device, said toy vehicle including a door and means for actuating and stopping said motor operative in response to the closed position of said door to stop said motor.
Claim 3
Dependent Claim
29 words
Device in accordance with claim 1, including a contact breaking device associated with said motor and said door that is closed in response to the opening of said door.
Claim 4
Dependent Claim
41 words
Device in accordance with claim 2, including a battery connected to said contact breaking device and a potential reducing resistor in circuit with said motor, whereby said motor is connected to said battery in response to closing said contact breaking device.
Claim 5
Dependent Claim
36 words
Device in accordance with claim 3, including a starting contact preferably disposed proximate said contact breaking device, operative to be closed briefly in response to closing said door and supply the full potential to said motor.
Claim 6
Dependent Claim
34 words
Device in accordance with claim 1, including a latching device proximate said door operative in response to the closed position of said door to assume its initial position in which said slide is free.
Claim 7
Dependent Claim
54 words
Device in accordance with claim 5, including a friction disc driven by said motor, a friction wheel in engagement with said friction disc and driven thereby, a noise producing means driven bY said friction wheel, and adjusting means operative to set the spacing between said friction wheel and the center of said friction disc.
Claim 8
Dependent Claim
23 words
Device in accordance with claim 5, including a resistor disposed in the circuit of said electro-motor and movable for adjustment by said slide.
Claim 9
Dependent Claim
43 words
Device in accordance with claim 5, including a membrane having components adapted to produce various sounds, clappers operative to actuate membranes, said membranes being adjustable relative to said clappers and means operative to place different membrane parts in actuating relation to said clappers.
Claim 10
Dependent Claim
14 words
Device in accordance with claim 8, including a biasing spring associated with said slide.
Claim 11
Dependent Claim
18 words
Device in accordance with claim 5 where said slide is operative to connect said motor to different potentials.
Claim 12
Dependent Claim
47 words
Device in accordance with claim 8, including a clapper support operatively connected to said friction wheel and supporting clappers and means responsive to low speed of said friction wheel to actuate only a part of said clappers and in response to higher speed to actuate all clappers.
