Description

[Detailed Description of the Invention] The present invention relates to a latching device for hanging a clock or the like on a wall.

Conventional latching devices for hanging a watch on a wall include those that have a hole for latching on the back of the watch body, and latching members that have holes or hook-shaped parts for latching. There is a watch that is attached so as to protrude from the upper end of the watch body (for example, Japanese Utility Model Publication No. 4686/1986). When hanging, the hanging holes or hook-shaped parts were hooked to hanging tools such as nails or screws driven into the wall or the like.

However, with watches that have a hole for hanging on the back of the watch, the hole is hidden and cannot be seen when hanging, making it difficult to hang and moving the watch while touching the back to a hanging device such as a nail. This has the disadvantage that it is often left in the latch position, which can damage the back of the watch. In addition, since the latching position is often at a high place, the watch body is often held and latched from below the latching position, and the latching hole or hook-shaped part is placed from the top of the watch body. A watch with a protruding locking member has the disadvantage that when latching the watch, the latching holes, nails, and other latching tools are hidden behind the upper edge of the watch body and cannot be seen, making it difficult to lock the watch.

In addition, in order to solve these shortcomings,
- In Publication No. 41841, a locking piece is provided on the back of the watch body so that it can swing freely in the vertical direction, and the lower end of the watch body is lifted up to make the locking piece and the nail that locks it visible. A dike is being proposed that will carry out latching work. However, even in this conventional technology,
When latching large and heavy objects such as equipment clocks, the lower end must be lifted while the latching operation is being carried out, and the installation location is often at a high place, making it difficult to maintain balance. This has the disadvantage that the latching process becomes extremely dangerous, and the watch itself remains movable even after latching has been completed, making it difficult to secure the watch so that it cannot fall off. It is difficult to guarantee safety.

Therefore, an object of the present invention is to enable the watch to be hung extremely easily and safely without damaging the back surface of the watch, and to ensure safety after the watch is hung.

Examples will be described below based on the drawings.

As shown in FIGS. 1 and 3, a front cover 4 is attached to the watch body 1 via a gasket 3 attached to the inner peripheral surface of a frame 2. Behind the front cover 4 is a dial plate. 5 are arranged. A timepiece mechanical body 6 is attached to the back of the dial 5 (as shown in the fifth figure), and pointers 7a and 7b are attached to a pointer shaft 7 that projects from the front of the dial 5. As shown in FIGS. 3 and 5, a support plate 8 is attached to the back of the watch body 1, and a butterfly plate 9 as a connecting means is attached to the upper edge of the frame 2.
It is attached so that it can swing vertically via the . An inclined guide groove 10 cut diagonally upward from the side is formed in the upper part of the support plate 8.
A latching hole 11 is formed at the upper end of the inclined guide groove 10. Further, a horizontally long through hole 12 is formed below the inclined guide groove 10 of the support plate 8. A threaded portion 13 is integrally protruded from the lower end of the support plate 8, and together with a wing nut 15, the watch body 1 is attached to the support plate 8.
It constitutes a connecting means that is unoscillatably connected to the. A locking portion 14 is provided at the lower end of the watch body 1, and the locking portion 14 is engaged with this connecting means.
By fitting the threaded part 13 into the threaded hole 14a drilled in 4 and screwing the wing nut 15 into the threaded part 13, the watch body 1 can be fixed to the support plate 8 without being able to swing. It's getting old. In addition,
16 is a latch shaft that engages with the latch hole 11, 17 is a fixed shaft that engages with the through hole 12, and 18 is a space between the watch body 1 and the support plate 8.

Next, the procedure for latching work will be explained.

First, the latch shaft 16 is screwed into the wall surface, and its head is separated from the wall surface by a gap equal to or more than the thickness of the support plate 8. Next, insert the screw part 13 into the screw hole 14a.
The watch body 1 is held in a vertical position with the wing nut 15 screwed into the threaded portion 13, that is, with the support plate 8 fixed so that it cannot swing. Then, as shown in FIG. 6, after positioning the latching shaft 16 in the space 18 between the watch body 1 and the support plate 8, the latching shaft 16 is brought into contact with the side 8a, and the latching shaft 16 is brought into contact with the side 8a.
When a is moved downward while pressing against the latching shaft 16, the latching shaft 16 enters the inclined guide portion 10, is further guided and reaches the latching hole 11, and the latching hole 11 is connected to the latching shaft 16. It is locked. Next, remove the wing nut 15 from the threaded part 13, and
is swung to expose the support plate 8 to the front side, and the fixed shaft 17 is screwed into the wall surface in alignment with the through hole 12 and fixed. As a result, movement of the watch body 1 in the vertical direction is restricted, and the engagement between the latch portion 11 and the hook 16 is prevented from coming off, so that the watch body 1 is fixed so that it cannot fall off. At this time, even if the screwing positions of the latch shaft 16 and the fixed shaft 17 are slightly shifted, the through hole 12
Since it is formed horizontally, the watch body 1 can be hung vertically. After further screwing in the latch shaft 16 to bring the wall surface and support plate into close contact, return the watch body 1, fit the threaded part 13 into the screw hole 14a again, and screw the wing nut 15 into the threaded part 13. The latching is completed by fixing the watch body 1 to the support plate 8 in a non-swingable manner, and the watch body 1 is fixed to the wall and will not easily come off.

As described above, according to the present invention, the latching operation can be performed extremely easily and safely without damaging the back surface of the watch or the like. It is also ideal as a latching device for public clocks such as facility clocks, as it can fix clocks and other objects to walls so that they cannot fall off, and is extremely safe after latching.
