Description

[Detailed Description of the Invention] The present invention relates to a pendulum device. In a conventional pendulum device, an edge portion for integrally supporting the pendulum is formed in the lower case, upper case, frame, or the like of the watch mechanical body. For this reason, the edge portion is made of the same material as the case, etc., and it is not possible to use a different material that is particularly suitable for the edge. In addition, when placing the V-groove of a swing rod on the edge, the V-groove is pressed from the upper position toward the edge against the claw provided to prevent it from slipping out, which may damage the edge and leave an extra gap at the top of the edge. However, it has disadvantages such as requiring a The present invention eliminates these conventional drawbacks, and provides a pendulum device that can select and use a suitable material for the edge part, easily replace the edge part if it is damaged, and is easy to assemble. It is something. An embodiment of the present invention will be described. FIG. 1 is a front view of the main parts, showing the back side of the device. Furizao 1 shown in illustrations 1 to 3
A substantially cylindrical swinging center body 2 is formed at the upper end of the swing body 2 in the horizontal direction in the front and back directions. Downward V grooves 3a and 3b having a center angle of approximately 120 degrees are formed on the lower surfaces of the front and rear ends of this swing center body. swinging rod
A magnet holding portion 4 is provided at the lower end of the magnet. As shown in Figures 1 and 4 to 6, the frame 5 has a mechanical attachment part 6 in the center and a window 7 in which a coil (not shown) facing the magnet attached to the swinging rod is located in the lower part. A drive circuit mounting portion 8 and a battery storage chamber 9 are provided on the side. Guide grooves 10 are formed in the upper surface of the frame 5 in the horizontal direction in the front and rear directions corresponding to the swing center body 2. Presser plates 11a and 11b face each other with a predetermined gap from both sides of the guide groove. At the top of the guide groove 10,
An arch-shaped cover portion 12 into which the swinging center body 2 is fitted and rotatable is integrally provided. Cover part 1
A notch 13 is formed in a part of 2 to facilitate insertion of the swing center body 2. As shown in the first and seventh to ninth figures, a guide portion 15 that can be inserted into and removed from the guide groove 10 is formed on the support member 14 of the swinging rod. Both sides of the guide part are presser plates 1
Thin part 16a that can be inserted into the lower surface of 1a, 11b,
16b, and a plurality of approximately hemispherical protrusions 17 are provided on the upper surface of this thin interior so that the guide groove can be inserted into the guide groove without loosening. Guide part 15
Edge portions 18a, 1
8b is formed in a protruding manner, and the V-grooves 3a and 3b of the swing center body 2 can be placed on this edge portion. A degree determining means is provided between the support member 14 and the guide groove 10. That is, a cut groove 19 is formed between the guide portion 15 and the front end (upper part of FIG. 7) of the thin wall portion 16b.
is provided, so that the front end portion 16c of the thin portion 16b has elasticity. Further, a protrusion 20 is formed on the outside of the front end portion 16c. On the other hand, a locking step 21 (shown in the sixth figure) is provided at the front end outlet of the guide groove 10.
is provided so that the protrusion 20 can be locked. In addition, near the rear end of the guide part 15 (lower part in FIG. 7), there is no thin wall part, but there are two defining parts 22a and 22b that have the same wall thickness as the guide part and extend to both sides. It abuts against the rear end surfaces of 11a and 11b to prevent further intrusion. Therefore, in order to attach the swinging rod 1 to the frame 5 , as shown in FIG .
Place the V-grooves 3a and 3b of the swinging center body 2 on the edges 18a and 18b of the frame 5 (shown by chain lines), and move the guide portion 15 in the direction of the arrow from the rear end of the guide groove 10 of the frame 5 to the front end, that is, the present device. Insert it by sliding it from the back to the front. As a result, the swing center body 2 fits into the cover part 12 with a small gap. Once fitted, the swinging center body 2 is connected to the edge 1.
8a and 18b block the front and back, and there is no gap for escape to the upper part by the cover part 12, so it will no longer escape. When inserting the guide portion 15 into the guide groove 10, the front end 16c of the thin wall portion 16b is bent into the cut groove 19, so that the protrusion 20 can enter into the guide groove 10. In addition, the protrusions 17... are determined by the depth of the guide groove 10 and the thin wall portion 16a,
It acts to compensate for the difference in wall thickness of 16b and eliminate looseness. When the guide part 15 is fully inserted into the guide groove 10, the degree determining part 22a of the guide part,
22b comes into contact with the rear end surfaces of the holding plates 11a and 11b to prevent further intrusion, and the front end 1
6c protrudes from the guide groove, and the protrusion 20 is locked to the locking step 21 by the spring force of the front end. Furthermore, since the cover part 12 is provided with a notch 13, first insert only the support member 14 halfway into the guide groove 10, and then insert the V grooves 3a and 3b of the swing center body 2 from the notch 13 into the edge. It may be placed on 18a and 18b and then slid and inserted as described above. As described above, according to the present invention, since the supporting member of the swing rod is made a separate member from the frame, the supporting member can be made of the most suitable material for the edge, and the durability of the edge can be increased. Furthermore, if the edge is damaged, only the support member can be replaced. It also has many excellent effects such as ease of assembly.
