Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a thin clock such as a wall clock.

(Prior Art) One of the most well-known structures for wall clocks is that a dial is placed in front of the mounting plate of the clock mechanism, and a front cover is installed in front of the dial.
Some models have a pointer between the front cover and the dial. By the way, in recent years, the demand for watches that are lighter, thinner, and smaller has increased, and making watches thinner has become an extremely important technical issue. As a result, the distance between the dial and the front cover, and the distance between the dial and the mounting plate of the watch mechanism are extremely narrow, and the front cover, dial, mounting plate, and other points themselves are also very narrow, unless their strength is affected. It is formed extremely thin.

(Problem that the invention aims to solve) However, due to the extremely thin structure of the watch, there is a risk that the front cover and the mounting plate of the watch mechanism will deform due to temperature deformation, pressure applied when turning the hands, etc. As a result, this front cover may push the hands, especially the minute hand, causing the minute hand to stop interlocking with the minute hand axis, or the front cover to be scratched by the minute hand, or worse. In this case, the clock will stop.

Therefore, an object of the present invention is to maintain a constant gap between the front cover and the dial even if the front cover and the mounting plate of the watch mechanical body are deformed.

(Means for Solving Problems) The present invention is characterized in that a dial plate 2 is arranged on the front side of the mounting plate 1 of the watch mechanical body, a front cover 3 is arranged on the front side of this dial plate, In a watch in which a pointer 5 is provided in a narrow gap between the front cover and the dial, a decorative body 6 is attached to a locking body 9 inserted from the back side of the front cover.
The locking body is fixed to the front surface of the cover in a protruding state, and the front surface of the dial abuts or is close to this locking body.

(Function) Therefore, even if the front cover 3 is deformed due to temperature or pressurized during hand turning operation, the locking body 7 that fixes the decorative body 6 to this cover and the dial plate 2 will come into contact with each other. As a result, a gap between the front cover 3 and the dial 2 is maintained, and the front cover does not come into contact with the pointer.

(Example) An example of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, in the thin watch according to the present invention, a dial plate 2 is located in front of a watch mechanical body mounting plate 1 which also serves as a rear frame, and in front of this dial plate there is a narrow A thin transparent front cover 3 is disposed with a gap in between. A watch mechanical body 4 is installed in the recess at the center of the back of the mounting plate 1, and this mechanical body controls the minute hand, which is located in the gap between the dial plate 2 and the front cover 3. A hand 5 consisting of an hour hand is rotatably driven. In addition, the front cover 3 has a decorative body 6 on the front side of the cover.
is located. Of this decorative body 6, 12 o'clock, 3
The decorations at the hour, 6 o'clock, and 9 o'clock positions are formed between the dial plate 2 and the front cover 3 and the mounting plate 1 by screws 7 inserted from the back side of the mounting plate 1.
They are strongly connected with the intervening state.

As shown in FIG. 3, the remaining decorative body 6 is fixed to the front surface of the cover by screws 8 serving as locking bodies being screwed into the rear surface of the cover. Further, a protrusion 2a is integrally formed on the dial plate 2 at a position facing the screw head of the screw 8, and this protrusion is close to or in contact with the male screw. Furthermore, a support column 1a is formed on the mounting plate 1, and the tip end surface of this support column is in contact with the back surface (bottom surface in FIG. 3) of the protrusion 2a of the dial plate.

Therefore, even if the mounting plate 1 or the front cover 3 tries to deform due to external force, the protrusion 2a of the dial plate 2 will come into contact with the screw head of the screw 8 that fixes the decorative body 6 to the front cover. Therefore, this deformation is prevented, so that the gap between the front cover 3 and the dial 2 is kept constant, and the front cover is prevented from coming into contact with the pointer. Note that the shape of the protrusion 2a is different from that of the dial 2 in order to ensure contact with the locking body 9.
However, depending on the size of the locking body, this protrusion is not necessarily limited to a protruding shape. For example, as shown in FIG. 4, if the decoration mounting portion 3a of the front cover 3 is recessed toward the back side, the dial 2 can be made into a simple flat plate.

Further, the decorations 6 are provided at positions corresponding to the respective time display positions, and function as indicators. Of course, the shape of the decorative body 8 itself can also be made into the shape of Roman numerals, Arabic numerals, etc. representing scale numbers.

(Effects of the invention) Since the present invention has the above-described configuration, even if the front cover tries to deform due to temperature, external force, etc., the front cover and the dial can be fixed by the contact between the locking body and the dial. The gap between the front cover and the pointer is kept constant, and this prevents the front cover from coming into contact with the pointer.This prevents the front cover from being scratched by the pointer, the pointer stopping to rotate, and preventing the front cover from coming into contact with the pointer.
This prevents the clock from ceasing to operate. Furthermore, if a decorative body is provided at the time display position, it can also function as an indicator and produce a design effect as a three-dimensional character.
