Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
217 words
A remote control device for an electrically motor driven toy comprising: a hollow member free to expand and contract under air pressure; manually operable means coupled to said hollow member by means of a flexible tube for conducting air pressure to said hollow member, to selectively expand and contract said hollow member; stop means spaced from one end of said hollow member for limiting the expansion of said hollow member to a predetermined range; resilient holding means for maintaining the other end of said hollow member at a substantially fixed position, during expansion of said hollow member up to the limit of said predetermined expansion range defined by said stop means, said resilient holding means maintaining said other end of said hollow member such that said otheR end of said hollow member is displaced during further expansion of said hollow member beyond said predetermined expansion range upon application of further air pressure by said manually operable means; a steering mechanism coupled to said hollow member and controlled by the expansion and contraction of said hollow member within said predetermined expansion range; and a switching mechanism coupled to said hollow member and controlled by the expansion and contraction of said hollow member beyond said predetermined expansion range, said switching mechanism being further coupled to and controlling said motor.
Claim 2
Dependent Claim
217 words
A remote control device for an electrically motor driven toy comprising: a hollow member free to expand and contract under air pressure; manually operable means coupled to said hollow member by means of a flexible tube for conducting air pressure to said hollow member, to selectively expand and contract said hollow member; stop means spaced from one end of said hollow member for limiting the expansion of said hollow member to a predetermined range; resilient holding means for maintaining the other end of said hollow member at a substantially fixed position, during expansion of said hollow member up to the limit of said predetermined expansion range defined by said stop means, said resilient holding means maintaining said other end of said hollow member such that said otheR end of said hollow member is displaced during further expansion of said hollow member beyond said predetermined expansion range upon application of further air pressure by said manually operable means; a steering mechanism coupled to said hollow member and controlled by the expansion and contraction of said hollow member within said predetermined expansion range; and a switching mechanism coupled to said hollow member and controlled by the expansion and contraction of said hollow member beyond said predetermined expansion range, said switching mechanism being further coupled to and controlling said motor.
Claim 3
Dependent Claim
35 words
The control device according to claim 1, wherein the holding means is a compression coil spring disposed between the other end of the hollow member and the toy body and exhibiting a predetermined compressive force.
Claim 4
Dependent Claim
26 words
The control device according to claim 1 further comprising means biasing said one end of said hollow member in a direction to contract said hollow member.
Claim 5
Dependent Claim
122 words
The control device according to claim 3 wherein said switching mechanism comprises a rotor provided with a pair of contact members and a plurality of ratchet teeth formed on the peripheral edge of said rotor; four fixed contact members which are selectively engaged with or detached from the movable contact members according to the rotation of the rotor and which, thereby selectively change the direction of rotation of the motor and stop its rotation; and an actuating plate operated in interlocking relationship with said other end of said hollow member so as to rotate the rotor in one direction by means of said ratchet teeth during each reciprocation of said actuating plate during displacement of said other end of said hollow member.
Claim 6
Dependent Claim
17 words
The control device according to claim 1 wherein said hollow member is an elongated bellows-like air cylinder.
