For example, a human or animal shaped ornamental body fixed to the stage of a mechanical clock, incorporating a link mechanism made of a soft synthetic resin agent accommodated in the body of the ornamental body, and an arm portion of the link mechanism. The present invention relates to a timepiece ornament in which a joint portion is made to project from a shoulder portion of the ornament and an arm portion made of a hard synthetic resin material is attached.

管理が面倒であるという問題があった。(Problems to be solved by the invention) When the arm of the decorative body is connected to the link mechanism, workability is poor if the press-fitting means has a large pressurizing force, and workability is good if the press-fitting force is small, but it may drop or vibrate. There is a problem of easy separation. The fusing means requires a jig and a tool, and in particular, the ultrasonic welder device has a problem that it cannot be implemented unless the shape of the parts of the joint is a specific shape. There are two types of adhesives, one is an instant adhesive and the other is an adhesive that uses a mixture of two types of liquids. The former is vulnerable to impacts such as dropping, and the latter is troublesome to manage the adhesive in the bonding work process. There was a problem.

合は48〜53dbであった。Further, in the decoration of the mechanical timepiece, there is a problem that noise due to a collision sound between the link levers during the reciprocating rotation operation of the arm portion is large. In FIG. 4, the link mechanism housed inside the decorative body 2 includes a first link lever 6 and a second link lever 6 in which shaft portions 3 and 5 are rotatably supported in the body.
The link pin 8 comprises a link lever 8, and the through hole 10 provided in the first link lever 6 has a connecting pin provided at one end of the second link lever 8.
12 is penetrated and the other end 14 of the second link lever 8 is indicated by arrow A.
Drive lever 16 that swings in the front-back direction of the decorative body 2 like
Is engaged with. With this configuration, the drive lever 16 moves in the direction of arrow A.
When reciprocating in the direction, the arm portion 4 can be operated in the arrow B direction via the first link lever 6. During this operation, the drive lever 16 and the second link lever 8, the first link lever 6 and the second link lever 8 come into contact with each other, or the link levers 6 and 8 come into contact with the body of the decorative body 2 to cause noise during operation. It happens. The cause of the large noise is that the arm portion 4 and the first and second link levers 6 and 8 are formed of hard synthetic resin (for example, ABS resin). By the way, the volume of sound in this state is 60 to 63db, and the link levers 6 and 8 are made of polypropylene (ABS
It was 50 to 53 db when it was made of a resin softer than resin, and it was 48 to 53 db when the link lever 6.8 was made of a polyester elastomer (which is softer than polypropylene).

The first part of the present invention corresponds to the arm portion 4 of FIG. 4, and the second part corresponds to the first link lever 6 of FIG. The arm portion 4 is made of ABS resin, and a coupling hole 22 is provided at the coupling portion with the first link lever 6. Connecting hole
As shown in FIG. 3, a flat surface 24 is provided inside 22 so as not to rotate with respect to the first link lever 6.

As shown in the drawing, methylene chloride is applied as the organic solvent 32 to the entire inner surface of the coupling hole 22 of the arm portion 4 and the coupling protrusion 26 of the first link lever 6 is simply inserted into the coupling hole 22. The organic solvent 32 has a function of melting (including softening) a styrene-based synthetic resin such as ABS resin, and has almost no function of melting (including softening) with respect to the polyester elastomer. Therefore, the melted material 32 melted by the organic solvent 32 flows into the recess 28 provided in the coupling projection 26 as shown in FIG.

A convex portion 34 integrated with the coupling hole 22 is formed therein as shown in FIG. As a result, the connecting protrusion 26 is firmly connected to the connecting hole 22, and the arm 4 is integrated with the first link lever 6.

衝突音は小さくならない。As another structure for preventing the arm portion 4 from rotating with respect to the first link lever 6, a concave portion in the direction perpendicular to the peripheral surface of the coupling protrusion 26 is provided in the peripheral surface, and an organic solvent is used in the concave portion. A configuration may be adopted in which the melted melt enters and solidifies, or a configuration in which a small protrusion is provided on the peripheral surface of the coupling protrusion 26 and the melt is solidified around the protrusion. It should be noted that if ABS resin that melts the coupling projection 26 side with an organic solvent is used, the uneven portion of the slip-out preventing peripheral surface becomes unnecessary, but the collision noise between the link levers in the link mechanism does not decrease.

体内と当る為に生ずる騒音も小さくすることができた。(Effect of the Invention) According to the present invention, the peripheral surface of the connecting convex portion of the second component fitted in the connecting hole is provided in the first component formed of the synthetic resin agent that melts in the organic solvent. In the structure provided with the uneven portion, when a predetermined organic solvent is applied to the inside of the bonding hole and the bonding protrusion is fitted into the bonding hole, a melt generated by melting in the bonding hole by a chemical reaction is generated on the uneven surface of the bonding protrusion. It goes around and solidifies. As a result, the first component and the second component are joined together with a strong joining force. This joining work is extremely simple, and the handling and management of the organic solvent is also easy, and the joining between the parts is simplified as a whole. Furthermore, when the second component is bonded to the first component, even if the second component is formed of a member having a very weak bonding force when an organic solvent is used as an adhesive, the first component and the second component are strongly bonded. Combined by force. In addition, the noise generated when the link levers hit each other in the link mechanism or when the link levers hit the interior of the ornament can be reduced.
