Abstract
Abstract A toy having a movable element is provided with a magnetic actuator which includes a magnet that is placed in proximity to a magnetically attractable component of a transmission disposed within the toy for transmitting power from a motor to the movable element of the toy. The magnet is embedded in a play piece which is placed on the toy on a designated area in proximity to the magnetically attractable component.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
A toy comprising: a body; a movable element connected to the body; spring mechanical drive motor means with rotary release means, and being operatively connected to the movable element for moving the movable element; an actuator for selectively contacting and releasing the rotary release means; a first magnetic member linked to said actuator; and a second magnetic member for placement in contact with the body and being operative to move the actuator into and out of contact with the rotary release means by magnetic attraction with the first magnetic member, so that when the actuator is out of contact with the rotary release means, the drive motor outputs a rotary driving force to the movable element.
Claim 2
Dependent Claim
116 words
A toy comprising: a body; a movable element connected to the body; spring mechanical drive motor means with rotary release means, and being operatively connected to the movable element for moving the movable element; an actuator for selectively contacting and releasing the rotary release means; a first magnetic member linked to said actuator; and a second magnetic member for placement in contact with the body and being operative to move the actuator into and out of contact with the rotary release means by magnetic attraction with the first magnetic member, so that when the actuator is out of contact with the rotary release means, the drive motor outputs a rotary driving force to the movable element.
Claim 3
Dependent Claim
27 words
A toy according to claim 1, wherein the body has a vertical portion for supporting the movable element and a horizontal portion for housing the drive motor.
Claim 4
Dependent Claim
94 words
A toy according to claim 2, wherein one of the magnetic members is a piece of magnetic material carried by a distal end portion of a lever pivotally supported inside the body, the opposite end portion being linked to the actuator which is movable in response to movement of the lever into and out of engagement with an output member of the motor, and the other of the magnetic members is a magnet movable outside the body into and out of proximity to the magnetic material of the lever to magnetically move the lever.
Claim 5
Dependent Claim
35 words
A toy according to claim 1, wherein the motor is a spring-wound motor having a low speed/high torque output for driving the movable element and a high speed/low torque output comprises the rotary release means.
Claim 6
Dependent Claim
117 words
A toy comprising: a body; a rotatable wheel rotatably supported by the body; spring mechanical drive motor means with rotary release means, and being operatively connected to the rotatable wheel for rotating the rotatable wheel; an actuator for selectively contacting and releasing the rotary release means; a first magnetic member linked to said actuator; and a second magnetic member for placement in contact with the body and being operative to move the actuator into and out of contact with the rotary release means by magnetic attraction with the first magnetic member, so that when the actuator is out of contact with the rotary release means, the drive motor outputs a rotary driving force to the movable element.
Claim 7
Dependent Claim
117 words
A toy comprising: a body; a rotatable wheel rotatably supported by the body; spring mechanical drive motor means with rotary release means, and being operatively connected to the rotatable wheel for rotating the rotatable wheel; an actuator for selectively contacting and releasing the rotary release means; a first magnetic member linked to said actuator; and a second magnetic member for placement in contact with the body and being operative to move the actuator into and out of contact with the rotary release means by magnetic attraction with the first magnetic member, so that when the actuator is out of contact with the rotary release means, the drive motor outputs a rotary driving force to the movable element.
Claim 8
Dependent Claim
25 words
A toy according to claim 5, wherein the body includes a substantially horizontal portion and a substantially vertical portion extending upwardly from the horizontal portion.
Claim 9
Dependent Claim
133 words
A toy according to claim 6, further comprising a lever having a proximal end, a distal end, and a medial portion, and being pivotally connected at the medial portion to support means within the body, and having the first magnetic member disposed at the distal end and a linkage integrally formed at the proximal end, the linkage being operatively connected to a sliding bar, and the second magnetic member is movable outside the body to a position near the magnetic material of the lever for moving the lever by magnetic attraction, movement of the lever causing movement of the sliding bar through the linkage so that the sliding bar disengages and thereby releases the rotary release means which is permitted to rotate freely by the high speed/low torque output of the drive motor.
Claim 10
Dependent Claim
35 words
A toy according to claim 5, wherein the motor is a spring-wound motor having a low speed/high torque output for driving the movable element and a high speed/low torque output comprises the rotary release means.
