Abstract
A leverage mechanism actuating device includes a drive
member with an output shaft (121,321) to drive rotatably a
rotary body (13,33) around an axis. A force transmission member
(14,34) is moved relative to the rotary body (13,33) between
first and second positions by a centrifugal force generated
by a rotary driving force applied by the output shaft (121,321)
on the rotary body (13,33). Movement of the force transmission
member (14,34) 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 (24), and first and second locations. The
first location is associated operably with the force
transmission member (14,34). 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 (14,34) to result in a power output at the second
location for initiating motion of the toy.
Description
- 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.
- According to this invention, 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.

- Referring to Figs. 1 and 2, the first preferred embodiment of a leverage mechanism actuating device according to the present invention 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 amotor 12 with anoutput shaft 121 which extends upwardly through thebase seat 11 and which defines an axis. - The centrifuging mechanism includes a
rotary body 13 which is disposed above thebase seat 11 and which is driven by theoutput shaft 121 to rotate around the axis. Therotary body 13 has an arcuatesloping 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. Aball member 14 serves as a force transmission member, and is disposed rollingly on the slopingtrack face 132. As such, theball 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 therotary body 13 is driven rotatably by the output shaft. - The
transmitting plate 15 includes acircular plate 151 which is disposed above therotary body 13 to be moved upwardly by the lifting movement of theball member 14 in a direction parallel to the axis, anactuating member 152 which extends upwardly from the center of thecircular plate 151, and astop member 153 which is sleeved on the actuatingmember 152 on thecircular plate 151. - The leverage mechanism includes a
base plate 16 with at least twosupport stems 161 which are secured on thebase seat 11, acenter hole 162 for passage of the actuatingmember 152, and a guidingsleeve 163 which is mounted at thecenter hole 162 for guiding the movement of the actuatingmember 152. Anengaging seat 23 is secured on thebase plate 16. The leverage mechanism further includes aleverage member 21, such as a lid, which has anengaging block 22 to be pivoted in theengaging seat 23 by apin 24 so as to form a fulcrum. A central protrusion 25 (see Fig. 2) is formed on a bottom surface of theleverage member 21 and is aligned with the guidingsleeve 163 in the direction parallel to the axis of theoutput shaft 121. Thecentral protrusion 25 serves as a first location of theleverage member 21 and is associated operably with the actuatingmember 152. Theleverage member 21 further has a second location adapted to be connected to a toy (not shown). Moreover, the distance between a bottom surface of thebase plate 16 and thestop member 153 is shorter than a diameter of theball member 14, thereby preventing removal of theball member 14 from the slopingtrack face 132 during use. - With reference to Fig. 3, the
motor 12 can be controlled by acircuit 10, such as a voice-responsive sensor circuit, to rotate therotary body 13 via theoutput shaft 121, thereby generating a centrifugal force to move theball member 14 from the first position toward the second position. The transmittingplate 15 is lifted by theball member 14 in the direction parallel to the axis of theoutput shaft 121 with the assistance of the guidingsleeve 163. The actuatingmember 152 is moved upward to abut against theprotrusion 25 of theleverage member 21 so as to swing theleverage member 21 upwardly relative to the fulcrum, thereby resulting in a power output at the second location of theleverage member 21 for initiating motion of the toy. When themotor 12 ceases to be activated by the sensor circuit, therotary body 13 will stop rotating, and the transmittingplate 15 and theleverage member 21 will return back to their original positions, as shown in Fig. 2. - Referring to Figs. 4 and 5, 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 amotor 32 with anoutput shaft 321 passing through thebase seat 31. At least twosupport stems 361 are disposed on and extend upwardly from thebase seat 31 to connect securely with a resistingmember 36 of the leverage mechanism. The centrifuging mechanism includes arotary body 33 which is disposed above thebase seat 31 and which has two arcuate sloping track faces 332. Each slopingtrack face 332 has a lower end adjacent to the center of therotary body 33 and an upper end. Twoball members 34 are disposed rollingly on the sloping track faces 332, respectively, such that theball 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 transmittingplate 351, an actuatingmember 352 which extends upwardly from the transmittingplate 351 at the center of theplate 351 along a direction parallel to the axis of theoutput shaft 321, astop member 353 which is sleeved on the actuatingmember 352, and twoengaging seats 42 which are disposed on the transmittingplate 351 at two opposite sides of the actuatingmember 352. The resistingmember 36 is disposed above the transmittingplate 351, and has acenter hole 362 for passage of the actuatingmember 352, a guidingsleeve 363 which is disposed at thecenter hole 362, and two resistingportions 364 which are disposed at two opposite sides of thecenter hole 362. The leverage mechanism further has twoleverage members 41. Eachleverage member 41 has anaxial shaft 412 which extends transverse to the direction of the axis to divide theleverage member 41 into first and second locations 411,413, and which engages the respective one of theengaging seats 42 to form a fulcrum. - With reference to Fig. 6, the
motor 32 can be started by asensor circuit 30 to rotate therotary body 33 and generate a centrifugal force to move theball members 34 from the lower ends of the sloping track faces 332 toward the upper ends, respectively. The transmittingplate 351 is lifted by theball member 34 in the direction parallel to the axis of theoutput shaft 321 with the guidance of the guidingsleeve 363 so that thefirst locations 411 are moved upward to abut against the resistingportions 364 of the resistingmember 36 so as to swing upwardly thesecond locations 413 around the fulcrum, thereby resulting in a power output at thesecond locations 413 for initiating motion of the toy. When themotor 32 ceases to be activated by the sensor circuit, therotary body 33 will stop rotating, and theball members 34 will move back to the lower ends. As such, the transmitting plate 35 will return back to its original position, and thefirst locations 411 of theleverage member 41 will be released from abutting against the resistingmember 36. - As illustrated, the actuating device according to this invention applies a centrifugal force generated by the
rotary body ball member
