Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a pendulum device fixed to a swing rod.

(Prior Art) On the back surface of the movement case, a swing rod is attached so that it cannot be separated from the movement.
A pendulum that exerts a decorative function is fixed.

Conventionally, the pendulum has been vertically separated and fastened, as seen, for example, in Japanese Utility Model Publication No. 63-44785.
Specifically, a decorative body was worn on the upper end of the swing rod, and a traditional pendulum was hung on the lower end of the swing rod. Both the ornamental body and the traditional pendulum are oscillating with a swing rod,
Even if it is a separate body, it can be understood by the concept of a "pendulum".

When carrying the watch out to the market, lock the swing rod in place, remove the ornament and the pendulum from the swing rod and store them in the cosmetic box, and remove the back plate of the watch body when the customer uses it. The ornament and the pendulum were attached to the pendulum.

(Problems to be Solved by the Invention) The above conventional technique has the following problems.

If the ornament and the pendulum are separated, the number of parts will increase accordingly.

Annoying the customer's hand after the market is shipped.

Since the large back plate must be attachable / detachable, the large back plate causes a large amount of distortion, which makes mounting work difficult.

The present invention has been made to provide a pendulum device that solves the above problems.

(Means for Solving the Problem) That is, the pendulum device of the present invention is a pendulum device in which a pendulum is superposed and fastened in a laminated manner on the back surface of a swing rod provided on the back surface of the movement case and having a protrusion at the top end. In addition, it has a decorative body at each of the upper and lower ends, a fitting hole for the protrusion of the top end of the swing rod is provided in the upper part, and a U-shaped shape that wraps the left and right end edges of the swing rod in the center part. And a contact piece to the lower end of the swing rod.

(Operation) In the pendulum device of the present invention, the fitting hole is fitted to the projection of the top end of the swing rod, and the locking portion is fixed so as to enclose the left and right edges of the swing rod. It is firmly integrated with the swing rod. The pendulum is fastened to the pendulum at the factory.When the pendulum is used for transportation, the lock hole of the pendulum is generally fitted to the locking pin in the fixed state so that it does not move during transportation. Keep it. Therefore, the customer only has to disengage the swing rod from the locking pin at the time of use, and a force is applied to both the fitting hole and the locking portion at the time of fitting onto the locking pin and separating from the locking pin. The damage to the fitting hole or the locking portion is avoided.

Further, in the pendulum device having the above-mentioned configuration, it suffices that the back plate can be opened and closed in the vicinity of the locking pin and the battery box, and by installing a small door on the back plate, it is not necessary to attach and detach the entire back plate. I'm done.

(Example) Hereinafter, the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows an embodiment of the present invention, FIG. 1 is a longitudinal sectional view showing a timepiece body equipped with a pendulum according to the present invention, FIG. 2 is a front view of the pendulum, and FIG. FIG. 4 is a side view, FIG. 4 is a rear view showing the timepiece body with the pendulum removed, and FIG.
FIG. 6 is a vertical side view in the figure, FIG. 6 is a rear view showing a mounted state of a pendulum on a swing rod, and FIG. 7 is a perspective view of the mounted pendulum as seen from the rear side.

In the figure, 1 denotes a watch body, 2 denotes a movement case, and a vertically long swing rod 3 is attached to the movement case 2 in the center of the rear face thereof so as to be inseparable from the movement. In addition, 4 is a guide alignment axis, 5 is a pointer, 6 is a pointer axis, 7 is a dial, and 8 is a glass plate. Further, 9 is a projection formed on the top of the swing rod 3, 10 is an elastically deformable pressing protrusion disposed on the back side of the protrusion 9, and these protrusions 9 and 10 are It is used to fix the upper end of the pendulum 14 described later. Reference numeral 11 denotes a heavy hanging member disposed below the swing rod 13, and the lower portion of the swing rod 3 of the present invention does not have a pendulum locking portion as in the prior art. This is because, as will be described later, the pendulum 14 of the present invention is an integral body having decorative bodies 15 and 16 on the upper and lower portions, respectively.

Reference numeral 12 is a lock hole formed on one side of the lower portion of the swing rod 3, and the lock hole 12 is fitted to a locking pin 13 projecting from the back surface of the movement case 2, whereby The swing rod 3 is configured so as not to swing when the watch is transported.

Then, on the back surface of the above-mentioned swing rod 3, a pendulum 14 having decorative bodies 15 and 16 at upper and lower portions is superposed and fixed in a laminated manner. The pendulum 14 has a fitting hole 17 formed on the lower surface of the upper ornamental body 15 to be fitted into the projection 9, and is provided on the upper side of the lower ornamental body 16 under the pendulum 3. An abutment piece 18 for supporting the edge is provided, and a U-shaped engaging portion 19 for enclosing the left and right end edges of the center portion of the swing rod 3 is further provided at the center portion. 9 is fitted in the fitting hole 17, and the left and right end edges of the central portion of the swing rod 3 are locked by the locking portions 19.
If it is wrapped around, the contact piece 18 exists at the lower end of the swing rod 3. Further, the length of the pendulum 14 is such that the decorative bodies 15 and 16 are the glass plate 8 when the pendulum 14 is polymerized and attached to the pendulum 3.
It is set so that it can be seen through.

Reference numeral 20 denotes a receiving blade provided on both sides of the pendulum 14, and the receiving blade 20 has a certain width and length in the depth direction (the front-back direction of the timepiece body 1). That is, when the pendulum 3 and the pendulum 14 are stacked on the back surface of the movement case 2 as in the present invention, a large gap in the depth direction is generated between the movement case 2 and the back plate 21 to cause a battery box. When the battery is taken out of 22, the battery may fall into the large gap. Therefore, at the position to be matched with the lower edge of the back side of the battery box 22,
The receiving blade 20 is provided to prevent the battery from dropping. However, the receiving blade 20 may be provided on the swing rod 3.

The above-mentioned pendulum 14 is attached to the swing rod 3 in the factory, and both of the swing rods 3 are fitted and locked to the locking pins 13 and handed to the customer. Therefore, the customer opens the door body formed on the back plate 21 at the time of use and removes the swing rod 3 from the locking pin 13. At this time, the customer may have a pendulum 1 that may be nearby.
Although it is easy to remove the pendulum 4 by putting it on the hand 4, even if such an operation is performed, the pendulum 14 is integrally fastened to the pendulum rod 3 at the upper, middle, and lower portions, and therefore the pendulum 14 is not damaged. Escape. Further, since the contact piece 18 exists at the lower edge of the swing rod 3, the fitting hole 17 of the pendulum 14 and the projection 9 of the swing rod 3 cannot be disengaged from each other by some impact.

(Effects of the Invention) As described above, the present invention has a decorative body attached to each of the upper and lower parts of the pendulum, which is an integral body, and the number of parts is reduced, so that the pendulum is gripped when the initial lock of the pendulum is released. Even if a force is applied, since the U-shaped locking portion wraps both side edges of the swing rod, it does not cause unnatural and concentrated force,
There is no damage to the pendulum fitting hole or the pendulum projection. Further, since the contact piece exists at the lower end of the swing rod, the pendulum is not accidentally detached from the swing rod due to the existence of the corresponding contact piece.
