Description

[Detailed description of the invention] The present invention relates to a protection plate for the dial of a wall clock.The hand hook of the wall clock has a protective plate between the hole opening and the back of the dial to prevent nails, wood screws, etc. It is an object of the present invention to provide a protective plate capable of preventing damage to the back surface of a dial by the head of a tool.

FIG. 1 shows a sectional view of an example of a wall clock.

In the figure, 1 is a front case, 2 is a glass, and 3 is a dial plate, which are provided on a resin case 4.

5 is a movement (clock drive mechanism) that drives the clock hands 6.

Since such a wall clock is usually used by hanging it on an L-shaped metal fitting, the hole 7 of the hand hook provided in the rear case 4 is formed in a surface perpendicular to the back surface of the opening of the case 4, as shown by 7a. .

However, when using the wall clock by inserting a long nail or wood screw into the hole 7 for the needle hook, the head 8' of the nail 8 with one end fixed to the wall 9 as shown in FIG. The needle hook collides with the back surface of the dial plate 3 through the hole 7, and as a result, the front surface of the dial plate 3 may protrude and spoil the appearance.

FIG. 3 shows an example of the shape of the hook hole 7 into which the nail 8 is inserted from the dial 3 direction.

The shape of the hole 7 in the above needle hook can be made by splitting the mold for resin molding of the rear case 4 so that the head 8' of the nail 8 does not come into contact with the dial 3. In order to prevent the above phenomenon, conventionally the member 10 in which screw holes 10a to 10C1 and nail insertion holes 10d as shown in FIG. 4 were formed was replaced with a rear case as shown in FIG. 4
It was installed so as to cover the space 13 provided on the back side of the.

However, in the above conventional method, the screws are 11.
12 and another one not shown in the figure are required, which is relatively expensive, and the work of attaching and fixing the member 10 to the back of the rear case 4 using screws is complicated. This has the disadvantage that it takes time and furthermore, screws that are different from those of the rear case 4 are attached, which spoils the appearance and aesthetics of the rear case 4.

The present invention eliminates the above-mentioned drawbacks, and each embodiment thereof will be described with reference to the drawings from FIG. 6 onwards.

Figures 6A and 6B are perspective views of the first embodiment of the protection plate for the dial of a wall clock according to the present invention, and a perspective view showing the installation state thereof, and the same parts as in Figure 1 are designated by the same numbers. It is.

Reference numeral 14 in FIGS. 6A and 6B is a protection plate, and a mounting screw hole 14a is bored in its upper part, while a tongue piece 14b is formed in its lower part.

When the tongue piece 14b of the protective plate 14 is inserted into the opening 7a of the hook hole 7, the screw hole 14a is opposed to the boss 15 provided on the rear case 4.

Thereafter, as shown in FIG. 6B, the screw 16 is inserted into the boss 15 through the screw hole 14a to fix the protection plate 14.

As a result, as shown in FIG. 7, the head 8' of the nail 8 passes through the opening 7a but contacts the protection plate 14, but does not contact the dial 3. can be protected by

Furthermore, the work of attaching and fixing the protective plate 14 can be done using one screw, which improves work efficiency and reduces costs compared to the conventional method.

Next, a second embodiment of the present invention will be described.

FIGS. 8A and 8B show a perspective view and a side view, respectively, of a second embodiment of the wall clock according to the present invention.

Reference numeral 17 denotes a protection plate, which has a hole 18 drilled through the flat plate, and a tongue piece 17a for attachment on the peripheral edge of the hole 18.
, 17b, 17C, and 17d are provided at an angle with respect to the flat plate surface as shown.

The protective plate 17 has a hole 18 drilled in the protrusion on the back of the hole 7 for nail hanging.
is inserted, and after the tongue piece 17a is brought into contact with the bottom of the nail hook hole 7, the tongue pieces 17b and 17C are inserted, using the tongue piece 17a as a fulcrum.
, 17d are cylindrical nail hooks that are press-fitted into the side surfaces of the back surface of the hole 7 to fix the protection plate 17.

As a result, as shown in FIG. 9, the head 8' of the nail 8 passes through the opening 7a but contacts the protection plate 17 and does not contact the dial 3. It can be protected by 17.

Unlike the first embodiment, this embodiment does not require the screws 16 for mounting, so the mounting work can be carried out extremely easily.

Next, a third embodiment of the present invention will be described.

Figure 10 shows the third protection plate for the dial of the wall clock according to the present invention.
A perspective view of an example is shown.

In the figure, reference numeral 19 denotes a protection plate, which is made of an elastic member such as stainless steel and has a roughly U-shape, and has notches 19a and 19b formed at both ends, and a tongue piece 19C. There is.

On the other hand, the rear case 4 has an opening 7a as shown in FIG.
Key-shaped ribs 20 a and 20 b are disposed opposite to each other above.

First, pinch both sides of the protective plate 19 with your fingers and bend it toward the center, and insert the tongue piece 19C into the opening 7a as shown in FIG. 12A. Both sides of the key-shaped ribs 20a, 20
Push it inside b.

Next, the notches 19 a and 19 b form hook-shaped ribs 20 .
When the finger is released after being pushed to the stepped portions a and 20b, the restoring force of the protective plate 19 returns its deflection and the protective plate 19 is fixed as shown in FIG. 12B.

That is, FIG. 13 is a top view showing the installed state of the protection plate 19, and since the notches 19a and 19b of the protection plate 19 are fitted with the steps of the hook-shaped ribs 20a and 20b, Tongue piece 19 12th B with C as the fulcrum
In the middle, counterclockwise rotation is prevented.

Therefore, the protective plate 1 is
9, but in this case, the protective plate 19 is
The attached state shown in Figure B is maintained.

According to this embodiment, since there is no need to provide screws to fix the protective plate 19, the installation and fixing work is extremely simple and workability can be improved compared to the conventional method, and since it is configured to be inserted into the opening 7a, the shape can be reduced. It can be constructed at a low cost and has a high fixing strength, so the wall clock can be stably hung even with nails.

As mentioned above, the protection plate for the dial of the wall clock according to the present invention is
The nail hanger is installed between the back of the dial on the resin case of the wall clock and the hole opening, and is configured to abut the head of the hanger exposed through this opening, so that the hanger's This prevents the dial from being damaged or deformed due to the head hitting the back of the dial, and the protective plate can be press-fitted into the hole in the rear case nail hook or inserted into the opening or opening part of the rear case. The workability of mounting and fixing can be greatly improved compared to conventional fixing using multiple screws, and the rear case resin molding mold is not divided into molds, so fewer or no screws are used. Therefore, it has features such as being able to be constructed at low cost6.
