Definitions
- This invention relates to a leverage mechanism actuating device for use in initiating motion of a toy, more particularly to a leverage mechanism actuating device with a centrifuging mechanism which can convert a rotational force into a translational lifting force for actuating a leverage mechanism to initiate motion of a toy.
- a conventional actuating device for initiating motion of a toy usually has a large number of components, such as gears and electrical control circuits, thereby resulting in higher manufacturing and maintenance costs.
- the object of the present invention is to provide a leverage mechanism actuating device with a centrifuging mechanism which has a simple construction that is easy to fabricate at a relatively low manufacturing cost.
- a leverage mechanism actuating device includes a drive member with an output shaft.
- a centrifuging mechanism includes a rotary body which is driven rotatably by the drive member around an axis of the output shaft, and a force transmission member which is moved relative to the rotary body between a first position and a second position radially spaced from the first position by a centrifugal force generated by a rotary driving force applied by the output shaft on the rotary body. Movement of the force transmission member from the first position to the second position enables the force transmission member to convert the rotary driving force into a translational lifting force in a direction parallel to the axis.
- a leverage mechanism includes a fulcrum, and first and second locations. The first location is associated operably with the force transmission member. The second location is adapted to be connected to a toy. Thus, the first location is actuated by the translational lifting force of the force transmission member to result in a power output at the second location for initiating motion of the toy.
- the first preferred embodiment of a leverage mechanism actuating device is shown to comprise a drive member, a centrifuging mechanism, a transmitting plate 15, and a leverage mechanism.
- the drive member has a base seat 11, and a motor 12 with an output shaft 121 which extends upwardly through the base seat 11 and which defines an axis.
- the centrifuging mechanism includes a rotary body 13 which is disposed above the base seat 11 and which is driven by the output shaft 121 to rotate around the axis.
- the rotary body 13 has an arcuate sloping track face 132 with a lower end to define a first position and an upper end opposite to and extending upwardly from the lower end to define a second position.
- a ball member 14 serves as a force transmission member, and is disposed rollingly on the sloping track face 132. As such, the ball member 14 can be moved from the first position (i.e. the lower end) to the second position (i.e. the upper end) by a centrifugal force which is generated when the rotary body 13 is driven rotatably by the output shaft.
- the transmitting plate 15 includes a circular plate 151 which is disposed above the rotary body 13 to be moved upwardly by the lifting movement of the ball member 14 in a direction parallel to the axis, an actuating member 152 which extends upwardly from the center of the circular plate 151, and a stop member 153 which is sleeved on the actuating member 152 on the circular plate 151.
- the leverage mechanism includes a base plate 16 with at least two support stems 161 which are secured on the base seat 11, a center hole 162 for passage of the actuating member 152, and a guiding sleeve 163 which is mounted at the center hole 162 for guiding the movement of the actuating member 152.
- An engaging seat 23 is secured on the base plate 16.
- the leverage mechanism further includes a leverage member 21, such as a lid, which has an engaging block 22 to be pivoted in the engaging seat 23 by a pin 24 so as to form a fulcrum.
- a central protrusion 25 (see Fig. 2) is formed on a bottom surface of the leverage member 21 and is aligned with the guiding sleeve 163 in the direction parallel to the axis of the output shaft 121.
- the central protrusion 25 serves as a first location of the leverage member 21 and is associated operably with the actuating member 152.
- the leverage member 21 further has a second location adapted to be connected to a toy (not shown).
- the distance between a bottom surface of the base plate 16 and the stop member 153 is shorter than a diameter of the ball member 14, thereby preventing removal of the ball member 14 from the sloping track face 132 during use.
- the motor 12 can be controlled by a circuit 10, such as a voice-responsive sensor circuit, to rotate the rotary body 13 via the output shaft 121, thereby generating a centrifugal force to move the ball member 14 from the first position toward the second position.
- the transmitting plate 15 is lifted by the ball member 14 in the direction parallel to the axis of the output shaft 121 with the assistance of the guiding sleeve 163.
- the actuating member 152 is moved upward to abut against the protrusion 25 of the leverage member 21 so as to swing the leverage member 21 upwardly relative to the fulcrum, thereby resulting in a power output at the second location of the leverage member 21 for initiating motion of the toy.
- the motor 12 ceases to be activated by the sensor circuit, the rotary body 13 will stop rotating, and the transmitting plate 15 and the leverage member 21 will return back to their original positions, as shown in Fig. 2.
- the second preferred embodiment of the leverage mechanism actuating device of this invention is shown to comprising a drive member, a centrifuging mechanism, and a leverage mechanism.
- the drive member has a base seat 31, and a motor 32 with an output shaft 321 passing through the base seat 31.
- At least two support stems 361 are disposed on and extend upwardly from the base seat 31 to connect securely with a resisting member 36 of the leverage mechanism.
- the centrifuging mechanism includes a rotary body 33 which is disposed above the base seat 31 and which has two arcuate sloping track faces 332. Each sloping track face 332 has a lower end adjacent to the center of the rotary body 33 and an upper end.
- Two ball members 34 are disposed rollingly on the sloping track faces 332, respectively, such that the ball members 34 are moved by virtue of centrifugal force to the upper ends.
- the leverage mechanism is disposed above the rotary body 33, and has a transmitting plate 351, an actuating member 352 which extends upwardly from the transmitting plate 351 at the center of the plate 351 along a direction parallel to the axis of the output shaft 321, a stop member 353 which is sleeved on the actuating member 352, and two engaging seats 42 which are disposed on the transmitting plate 351 at two opposite sides of the actuating member 352.
- the resisting member 36 is disposed above the transmitting plate 351, and has a center hole 362 for passage of the actuating member 352, a guiding sleeve 363 which is disposed at the center hole 362, and two resisting portions 364 which are disposed at two opposite sides of the center hole 362.
- the leverage mechanism further has two leverage members 41.
- Each leverage member 41 has an axial shaft 412 which extends transverse to the direction of the axis to divide the leverage member 41 into first and second locations 411,413, and which engages the respective one of the engaging seats 42 to form a fulcrum.
- the motor 32 can be started by a sensor circuit 30 to rotate the rotary body 33 and generate a centrifugal force to move the ball members 34 from the lower ends of the sloping track faces 332 toward the upper ends, respectively.
- the transmitting plate 351 is lifted by the ball member 34 in the direction parallel to the axis of the output shaft 321 with the guidance of the guiding sleeve 363 so that the first locations 411 are moved upward to abut against the resisting portions 364 of the resisting member 36 so as to swing upwardly the second locations 413 around the fulcrum, thereby resulting in a power output at the second locations 413 for initiating motion of the toy.
- the actuating device applies a centrifugal force generated by the rotary body 13,33 to the ball member 14,34 so as to convert the same into a translational lifting force that is imparted to the leverage mechanism, thereby actuating the leverage mechanism so as to result in a power output at the leverage mechanism for initiating motion of a toy.
