Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a small pendulum lock structure of an integrated swing clock in which a small pendulum is provided inside the clock and the clock itself swings. When transporting the small pendulum, the small pendulum is securely fixed using the battery mounting part using a locking member from within the battery mounting part.

(Prior Art) When transporting a pendulum clock, an important issue was how to securely fix the swinging pendulum.

As shown in FIG. 4, when the pendulum 30 is outside the case of the watch or is visible or within reach, the pendulum 30 can be easily engaged and fixed to the case 34 with the locking member 32. However, in the case of a full-body clock with a built-in pendulum, the pendulum was completely invisible from the outside, so it was not possible to lock it easily.

Furthermore, since the watch itself is made up of extremely sophisticated parts, it is required to securely lock the watch so as not to damage the parts.

(Problems to be Solved by the Invention) The purpose of the invention is to provide a lock structure that can easily and reliably lock the pendulum so that it cannot vibrate, and also prevents forgetting to release the lock, in a full-body swing clock with a built-in pendulum. It's about doing. When transporting a full swing clock, take advantage of the fact that the battery is removed before transporting, and by drilling a hole through which the locking member is inserted into the battery mounting part from which the battery has been removed, and inserting the locking member into the hole. It is intended to hold a small pendulum in place.

(Means for Solving the Problem) The present invention includes a lock pin with a lock portion protruding in the radial direction, a battery mounting portion provided on the outer surface of the watch case, and a rotatable lock pin on the bottom surface of the battery mounting portion. A lock part insertion hole that can be held in a detachable manner, and a small pendulum that is disposed between both the locking pin provided inside the watch case and the lock part insertion hole, and is swingably supported inside the case. The small pendulum is configured such that the rod of the small pendulum is locked by being held between a locking pin and a locking portion of the locking pin by rotation of the locking pin.

(Example) Fig. 1 is a plan view showing the structure of the present invention seen from the back, Fig. 2 is a central vertical sectional view seen from the side of a full-body swing clock equipped with the present invention, and Fig. 3 is a plan view showing the structure of the present invention as seen from the back. FIG. 4 is a perspective view showing an example of a conventional lock structure.

Reference numeral 2 denotes a front case, and 4 denotes a rear case. A battery mounting part 12 is provided inside the upper part of the rear case 4, and an adjustment knob 24 protrudes from the center part.

Reference numeral 6 denotes a support shaft attached to the upper part of the front case 2 and the rear case 4, and a small pendulum 8 is swingably suspended from the support shaft 6.

The small pendulum 8 has a window 10 formed by hollowing out the center thereof, and a magnet 28 is attached below the window 10, and the magnet 28 is oscillated by an electromagnetic coil 26 installed nearby. It's summery.

Reference numeral 12 denotes a battery mounting part, into which a dry cell battery is mounted, and a lock part insertion hole 14 is bored in the inner part.

The lock portion insertion hole 14 is a hole having a shape through which the lock portion 16 provided at the tip of the lock pin 18 can pass.As shown in FIG.
When the locking pin 18 is inserted into the front case 2 and the locking portion 16 is rotated in the direction of the locking pins 20 and 22 provided on the front case 2, the small pendulum 8 is locked into the window 1 by the locking portion 16.
0 is pushed from the inside to the outside.

The small pendulum 8 pushed in this way comes into contact with the locking pins 20 and 22 provided in the direction in which it was pushed, and is locked while being held between the lock portion 16 and the locking pins 20 and 22. It's summery.

The lock pin 18 has a collar 17 as shown in Fig. 2.
is provided, and when the lock pin 18 is rotated after being inserted into the lock part insertion hole 14, the battery mounting part 1
Since the bottom surface of the lock pin 18 is disposed between the collar 17 and the lock part 16, the lock pin 18 will not fall out from the lock part insertion hole 14.

To release the lock, it is sufficient to simply rotate the lock pin 18 in the opposite direction to the direction used when locking and remove the lock portion 16 from the lock portion insertion hole 14.

(Effects of the invention) a. Even if the pendulum is completely invisible from the outside, it can be easily
Moreover, the swinging of the small pendulum can be reliably locked.

b After removing the battery, a lock pin is fitted into the lock insertion hole in the battery mounting part to lock the vibration of the pendulum, so the battery cannot be installed unless the lock pin is removed, so do not forget to remove the lock pin. Not at all.

c. It can be easily locked by simply fitting the lock pin into the lock insertion hole provided in the battery mounting part and turning it.

d. The small pendulum is held and locked by the locking portion at the tip of the locking pin and the locking pin provided on the case, so it will not come off due to vibrations or shocks during transportation.

As described above, the present invention is an epoch-making lock structure that allows the small pendulum of a total hand clock, which cannot be seen from the outside, to be locked easily and reliably.
