Description

  The present invention relates to a toy mainspring unit having a rotating shaft rotated by a mainspring spring.

  Conventionally, this kind of mainspring unit for toys is provided with a main body case that accommodates a spiral mainspring spring and is provided on the main body of the toy. The main body case is provided with a rotating shaft connected to an end portion on the center side of the mainspring spring. The rotary shaft tightens the mainspring spring by rotation in one direction, and is driven to rotate in the other direction when the mainspring spring is wound back by elastic force. Further, an eccentric weight is eccentrically provided on the rotating shaft via a clutch mechanism.

One end of the rotating shaft 17 passes through one side of the unit case 16 and protrudes to one side of the unit case 16. One end of the rotating shaft 17 is connected to the power generation unit 14. Further, the other end of the rotating shaft 17 is connected to the driven rotating shaft 19 via a clutch mechanism (not shown). This clutch mechanism transmits the rotation of the rotating shaft 17 to the driven rotating shaft 19 only when the rotating shaft 17 rotates in the forward direction.

  The drawstring reel 18 is rotatably provided on the side portion of the unit case 16, and the drawstring 21 is wound around the outer periphery. The drawstring 21 is led out to the outside from a lead-out hole 22 provided in the main body case 11, and is led out to the outside of the stuffed toy main body 2. An operation portion 23 is provided at the lead-out end portion. With this operation unit 23, the pull string 21 can be pulled from the outside of the stuffed toy main body 2.

  One end of the secondary rotary shaft 19 passes through the other side of the unit case 16 and protrudes to the other side of the unit case 16. An eccentric weight 13 is provided at one end of the driven rotary shaft 19.

  The eccentric weight 13 is provided eccentrically with respect to the slave rotary shaft 19 and is eccentrically rotated by the slave rotary shaft 19 rotated by the forward rotation of the rotary shaft 17 to vibrate the entire toy mainspring unit 3.

  The power generation unit 14 includes a columnar magnet unit 25 provided at one end of the rotating shaft 17 and a coil 26 facing the outer periphery of the magnet unit 25.

  The magnet unit 25 includes a columnar magnet unit body 31 provided coaxially with the rotary shaft 17 and an even number, for example, two magnet bodies 32 and 33 provided on the magnet unit body 31. .

  As a result, interest by rotation of the driving body and interest by actuation of the actuating element, that is, interest by movement of the toy 1 due to vibration of the toy mainspring unit 3 by eccentric rotation of the eccentric weight 13 accompanying rotation of the rotating shaft 17, and In addition, it is possible to obtain interest by light emission of the light emitting diode 43, and to improve the interest of the toy 1.

  Further, an even number of magnet bodies 32 and 33 are arranged on the outer peripheral portion of the magnet portion main body 31 of the columnar magnet portion 25 provided on the rotating shaft 17 so as to be alternately different in the circumferential direction. By arranging the coil 26 so as to face the outer peripheral portion of the magnet portion 25, the power generation portion 14 can be made relatively simple, the manufacturing cost can be suppressed, and the mainspring unit 3 for toy can be downsized. It is possible to cope with downsizing of the toy 1.

  Further, by using the light emitting diode 43 as the operating element, the service life can be extended as compared with the case where a light bulb or the like is used.

  The first magnetism receiving portion 56 is bent from one end portion side to the other end portion side of the coil 26, extends to one side of the magnet portion main body 31, and protrudes to the other end portion side of the coil 26. . Further, the first magnetic receiving portion 56 includes a plurality of, for example, two, along the axial direction of the rotary shaft 17 so that the plurality of first magnetic receiving terminals 56a face the outer peripheral surface of the magnet portion main body 31. , Each projecting.

  Further, the second magnetism receiving portion 57 is extended from the other end portion side of the coil 26 to the other side of the magnet portion main body 31, and a plurality of, for example, three second magnetism receiving terminals 57a are provided. Projections are provided along the axial direction of the rotary shaft 17 so as to oppose the outer peripheral surface of 31.

  Then, as shown in FIG. 6, the magnetic receiving terminals 56a and the magnetic receiving terminals 57a are arranged so as to be alternated in the axial direction of the magnet unit body 31 above the magnet unit body 31. The intervals corresponding to the 31 magnetic poles are substantially equally spaced. Each of the magnetic receiving terminals 56a and 57a is disposed on a concentric circle with the rotation shaft 17 as the center.

  The tire portion 55 is a rear wheel of the toy 51, for example, and has an outer peripheral surface formed of a member having elasticity and a relatively large friction coefficient on the surface, such as rubber, and is exposed to the outside of the toy main body 52. It is in contact with the surface to be driven.
