Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a music box toy in which a figurine such as a doll moves in a curved line.

[Prior art]

Previously, the applicant of the present invention proposed a music box toy in which a movable body moves on a trajectory drawing an epicycloid curve as the music box plays. This structure involves meshing a crown gear with a large gear on the side of the drum of a music box, fitting a support plate onto the shaft of the crown gear and fixing the arm, fitting a rotating shaft onto the arm, and connecting a rotating ring to the rotating shaft. The arm is fixed, the rotating ring is meshed with the internal gear of the support plate, a first permanent magnet is provided on the arm to make it revolve and rotate, and a magnetic member is attached to the upper outer surface of the case on which a movable object such as a doll is placed. The magnetic member was arranged opposite to the first permanent magnet.

The above structure has the disadvantage that the structure is complicated because the first permanent magnet itself is moved in a curved manner by revolution and rotation. Furthermore, since the movable body was fixed on the magnetic member, the movable body only followed the movement of the first permanent magnet, and the action of the movable body was restricted.

[Purpose of invention]

In view of the above-mentioned drawbacks, the present invention aims to simplify, stabilize quality, and reduce costs by creating a structure in which the drive magnet can move in a simple circular motion, and the glyphic object such as a doll can move without being restricted by the circular motion of the drive magnet. Our goal is to propose a music box toy that can provide a variety of actions.

[Structure of the idea]

The present invention consists of a music box, a driving magnet that moves in a circular motion in conjunction with the music box, a driven magnet that follows the magnet through a fixed plate such as a case, and a driven magnet that is movably fitted and positioned on the fixed plate. It consists of a movable plate that is moved by the driven magnet, and a glyph, such as a doll, supported by the movable plate.

(Example) The present invention will be explained below with reference to the illustrated example. As shown in FIGS. 1 and 2, the toy music box has a frame 10 of a music box 3 fixed on a bottom plate 2 of a case 1. A plurality of annular projections 1b are formed inside the upper fixed plate 1a of the case 1. An annular protrusion 1c is formed on the outer periphery of the fixed plate 1a of the case 1.

The above-mentioned music box 3 has a winding key 1 in which a barrel in a barrel 11 fixed on a frame 10 is screwed to a barrel.
It is rolled up in 2. Drum 1 with this whole drive source
3 is rotated under the control of a speed governor (not shown), and the music box is played by pulling a diaphragm (not shown) with a pin on the drum.

Spur gear 14 fixed to one side of the drum 13
A crown gear 15 is meshed with. The bearing lever 4 to which the crown gear 15 is fixed is rotatably held by a bearing 16 fixed to the frame 10. A long hole 4b is formed in the lever portion 4a of the bearing lever 4, and a shaft 17 holding a drive magnet 5 is fitted into the lever portion 4a to prevent it from coming off upward. The drive magnet 5 is fitted into a concentric groove 1d formed by an annular projection 1b of the case 1.

A movable plate 6 and a driven magnet 7 are placed on the fixed plate 1a of the case 1. A hole 6a larger than the outer diameter of the driven magnet 7 is bored in the center of the movable plate 6, and the center of the driven magnet 7 fitted in the hole 6a is a dimension α from the center of the drive magnet 5 as shown in FIG. It is configured to be on the center side of case 1. A glyph 1 such as a doll is placed on the movable plate 6 at a position away from the center.
8 is fixed. The glyph 18 may also be fixed on the driven magnet 7.

The operation of the music box toy is such that when the winding key 12 winds up the whole song, the music box 3 is played and the crown gear 15 is rotated. This rotation rotates the bearing lever 4 and rotates the drive magnet 5 in a circular motion within the groove 1d. When the drive magnet 5 is rotated, the driven magnet 7 is located on the center side of the case 1 with α dimension as shown in FIG.
The outer circumference of the movable plate 6 is pushed in the direction of the case 1.
The movable plate 6 is pressed against the inner circumferential wall of the annular jetty 1c on the outer circumferential portion of the movable plate 6, and is rotated and revolved around its axis.

When the movable plate 6 revolves and rotates, the glyph 1
8 moves on a trajectory that draws an epicycloid curve (not shown).

When the music box toy is configured as above,
Since the drive magnet 5 rotates in a simple circular motion, the structure for rotating the drive magnet 5 is simplified, and quality can be stabilized and costs can be reduced. Further, the quadrilateral body 18 can move on a locus drawing an epicycloid curve with a simple structure in which the movable plate 6 is provided for the simple circular rotation of the driving magnet 5.

The driving magnet 5 may be fitted into another concentric groove 1e, and the outer diameter of the movable plate 6 may be made large. Furthermore, the movable plate 6 may be formed to have an outer shape other than a perfect circle.

As described above, drive magnet 5 is connected to groove 1d and groove 1.
The radius of rotation of the drive magnet 5 can be easily changed by selecting which groove of the drive magnet 5 to install it.

Furthermore, the movable plate 6 is adjusted to match this rotation radius.
If you prepare Case 1, you can use case 1 in common to perform a variety of actions.

Furthermore, when the quadrangular body 18 is fixed to the movable plate 6, it is possible to draw epicycloid curves with various shapes depending on the fixed position.

FIG. 4 shows a modification of the movable plate, in which a downward pin 19 is fixed to one side of the movable plate 8 and is inserted into a hole 1f having an inner diameter larger than the outer diameter of the pin 19 drilled in the fixed plate 1a of the case 1. has been done. Further, the movable plate 8 has an elongated hole 8a into which the driven magnet 7 is fitted. The length of the elongated hole 8a is made shorter than the diameter β of the circular motion locus of the drive magnet 5 or the sum of the diameter of the circular motion locus plus the diameter of the driven magnet 7. A quadrangular body 18 is fixed at a position away from the center of the movable plate 8. Further, a glyph 18 is fixed outside the movement range of the movable plate 8 on the fixed plate 1a.

In the operation of this modification, when the music box 3 is played and the driving magnet 5 is moved in a circular motion, the driven magnet 7 is moved above the driving magnet 5 in a circular motion. The movable plate 8 is swung in the direction B by the circular motion of the driven magnet 7, and the pin 19
The inner diameter of the hole 1f is larger than the outer diameter of the elongated hole 8a.
Since the length is formed to be shorter than the diameter of the circular motion locus of the drive magnet 5, when the driven magnet 7 hits the end of the elongated hole 8a, the movable plate 8 is moved in the moving direction D of the driven magnet 7, resulting in movement and oscillation. This is a reciprocating motion of repeated motion, and the glyph 18 is moved by the reciprocating motion.

In this modification, the driving structure of the case 1 and the driving magnet 5 is substantially the same as that of the embodiment shown in FIGS. 1 and 2, and can be used in common. Further, by simply providing a fulcrum by the hole 1f of the fixed plate 1a and a fulcrum by the pin 19 of the movable plate 8, a complex motion of rocking and moving can be easily obtained. In addition, each of the glyphs 18 is fixed on the fixing plate 1.
a upper part and driven magnet 7 upper part and movable plate 8
By fixing them to the upper part, it becomes possible to stop, fix, and swing the glyphs 18, respectively.

Further, in this modification, the long hole 4b formed in the bearing lever 4 of the first and second embodiments is omitted, and the shaft 17 of the drive magnet 5 is prevented from coming off upward.

FIG. 5 shows a modification of the movable plate 8, in which a rectangular long hole 8b is bored.

FIGS. 6 and 7 show other modifications of the movable plate, in which a shaft portion 4c of a bearing lever 4 of a crown gear 15 is supported on the fixed plate 1a of the case 1, and decorations (not shown) are projected upward. is fixed. A downward pin 19 is fixed to one side of the movable plate 9 and inserted into a hole 1g formed in the fixed plate 1a of the case 1. Further, the movable plate 9 has an elongated hole 9a into which the driven magnet 7 is fitted.
The arc-shaped shaft portion 4c is located on both sides of the middle of the elongated hole 9a.
An escape hole 9b into which is fitted is bored. Long hole 9a
The length is slightly longer than the sum of the diameter of the circular motion locus of the driving magnet 5+the diameter of the driven magnet 7.

In the operation of this modification, when the music box is played and the driving magnet 5 is moved in a circular motion, the driven magnet 7 is moved in a circular manner. The movable plate 9 is swung in the B direction by the circular motion of the driven magnet 7.
