Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a watch latching device.

[Prior Art] Conventionally, when a wall clock is used in a general household or when a specific person comes in and out, a latching hole formed on the back of the clock is attached to the hook of a latching device fixed to a wall, etc. It is hung and attached. Also, in theaters and assembly halls where the public enters and exits, equipment clocks are used and are firmly fixed to the walls.

[Problems to be Solved] The wall clocks used at home and the like described above are easy to hang and remove, and are convenient for battery replacement, time adjustment, etc. As is well known, the performance of clocks has improved significantly in recent years, and there is no problem in terms of performance even if a home clock is used as an equipment clock in a public hall or the like. However, as mentioned above, household wall clocks are designed to be easily removed, so if they are hung in a public place, there is a high risk of theft. Further, when the above-mentioned equipment clock is used, it inevitably becomes large and expensive, and there is also the problem of high installation costs.

The purpose of the present invention is to provide a clock latching device that, once latched, cannot be easily removed unless one is familiar with the latching mechanism and configuration. The object of the present invention is to enable the clock to be used as an equipment clock without fear of theft.

[Means for Solving the Problems] A feature of the present invention is that it includes a means for restricting a watch from being easily removed once it has been hung.

That is, in the first invention, the latching device for hanging the watch has a latching hook and a fixing part projecting forward above the hook, and a latching device for latching the watch is provided on the back of the watch. A possible latching hole is formed. Further, on the back of the watch, a protruding portion is provided above the latch hole so as to be able to face the upper surface of the fixing portion. A fixing screw is then passed through this protrusion and screwed onto the fixing part to prevent the watch from coming off.

In the second invention, the latching tool is provided with a protruding support column having a swingable retaining piece at its tip above the fixing part thereof. Further, the protrusion provided on the back of the watch is formed with a through hole through which the retaining piece protrudes above the protrusion when the latch hole is engaged with the hook. When the retaining piece is swung while protruding from the upper surface of the protrusion, it faces the protrusion and prevents the watch from coming off.

Furthermore, in the third invention, the latching tool is provided with a protruding regulating protrusion having a head at its tip above the fixing part thereof. Furthermore, in place of the protrusion, a lock member that is slidable in the horizontal direction is provided on the back of the watch. This locking member is provided with a regulating piece consisting of a base that can closely face the upper surface of the fixing part and a regulating part that extends horizontally from this base via a connecting part, and this regulating piece has a regulating protrusion. A guide hole through which the lock member can be inserted is formed in a substantially L shape from the front end of the base toward the regulating part, and when the locking member is slid horizontally, the guide hole is formed in a substantially L-shape. and controls the departure of the clock.

[Function] In the first idea, the fixing part and the protrusion are made to face each other, and the fixing screw is screwed into the fixing part by passing through the protrusion, and in the second idea, the fixing screw is provided at the tip of the support column. By making the retaining piece protrude above the protrusion from the through hole of the protrusion, and by swinging the retaining piece to face the protrusion, the third invention further provides an L-shaped locking piece to the regulating protrusion. With the entrances of the guide holes facing each other, hook the latching holes to the hooks,
After that, when you slide the locking member horizontally,
By the head of the regulating protrusion facing the regulating part,
In either design, it becomes impossible to move the clock up or down, and it becomes impossible to remove the clock.

[Examples] Examples of the present invention will be described below with reference to the drawings.

The first idea is that, as shown in FIGS. 1 to 3, a latching tool 1 is fixed to a wall W, and a latching hook is formed at the lower end of a mounting part 1a of this latching tool 1. A latching hole 3 formed on the back surface of the watch 2 is latched to 1b. The latching tool 1 is provided with a fixing part 1c projecting forward above the latching hook 1b, and a female thread 1d is formed in the fixing part 1c. A protrusion 4 is formed above the latch hole 3 on the back of the watch 2 so as to protrude and be able to face the upper surface of the fixing part 1c. This protrusion 4 is provided with an insertion hole 4a for a fixing screw 5.

After the latching hole 3 is latched to the latching hook 1b as described above, the fixing screw 5 is inserted into the insertion hole 4a of the protrusion 4 and screwed onto the female thread 1d of the fixing portion 1c. Even if you try to lift the watch 2 and remove it from the latching hook 1b in this state, it is impossible to lift the watch 2 because it is fixed by the fixing screw 5.
The watch 2 cannot be removed from the latch 1 unless the connection between the protrusion 4 and the watch 2 is released.

As shown in FIG. 4, the second device has a support column 11d projecting from the upper surface of the fixing part 11c of the latch 11, and a retaining piece 1 at the tip of the support column 11d.
1e are swingably connected via pins 11f. A latch hole 13 is provided on the protrusion 14 that protrudes from the back of the watch so that it can face the fixing part 11c.
A through hole 14a is formed through which the retaining piece 11e projects above the protrusion 14 when it is hooked to the protrusion 14. Once the retaining piece 11e is swung to face the protrusion 14 (as shown by the chain line in FIG. 4), even if an upward force is applied, the retaining piece 11e will stand up and come off due to this force. In order to prevent this, the lower end portion is made slightly larger than the concentric circle of the fulcrum pin 11f.

To attach the watch to the latch 11 in the second invention, put the retaining piece 11e in an upright state, insert it into the through hole 14a of the protrusion 14 on the back of the watch, make it protrude upward, and attach it to the latch hole. 13 on the hook 11b. After that, when the retaining piece 11e is brought down to a horizontal state, that is, facing the upper surface of the protrusion 14, the upward movement of the protrusion 14 is restricted by the retaining piece 11e, and the watch cannot move up or down. The watch cannot be removed from the latch 11 unless the retaining piece 11e is made upright again.

In the third invention, as shown in FIGS.
A regulating protrusion 21e having a T-shaped cross section and having a T-shaped cross section is erected. Latching hook 21b of the latch tool 21

As shown in FIG. 6a, the locking member 25 has a regulating piece 25b bent rearward from the upper side of the sliding portion 25a. The regulating piece 25b has a base 25c that can closely face the upper surface of the fixing part 21c of the latching tool 21.
It consists of a connecting part 25d, which is an inclined surface that is bent upward and continuous with this base part, and a regulating part 25e, which is bent in the horizontal direction and continuous with this connecting part 25d. As shown in FIG. 6b, the base portion 25c, the connecting portion 25d, and the regulating portion 25e are provided with a substantially L-shaped guide hole 25 for guiding the regulating protrusion 21e.
f is provided. In addition, the sliding groove 2 is provided in the sliding portion 25a.
5g is opened horizontally.

Above the latch hole 23 on the back of the watch 22, there are 2
A book guide pin 26 is provided horizontally through the sliding groove 25g of the lock member 25, and the lock member 25 is attached to the watch 22 so as to be slidable in the horizontal direction while being guided by the guide pin 26. be.

To attach the watch 22 to the latch 21 in the third invention, the locking member 25 is moved to the right as shown by the solid line in FIG. 5, and the regulating protrusion 21e is aligned with the entrance of the guide hole 25f. . Next, the upper end of the latching hole 23 is latched onto the latching hook 21b, and the watch 22 is pushed toward the wall. Finally, when the locking member 25 is slid to the left as shown by the chain line in FIG. are in contact with each other, and movement of the watch 22 in the vertical direction is restricted. The watch 22 that has been locked in this manner has the lock member 25 locked again.
It cannot be removed unless it is slid to the right in the figure.

[Effects] As explained above, the latching device of the present invention has the following effects:
Once a clock has been latched, it cannot be easily removed unless one knows the mechanism and composition of the latching mechanism. Therefore, for example, if a household clock is used as an equipment clock in a place where the public accesses, there is a risk of theft. It can be used without worry. Since the structure is simple, it can be provided at an extremely low cost, and the latching operation is easy, which is a remarkable effect.
