Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a frame structure of a watch.

[Prior art] Conventionally, when a watch frame is composed of two parts,
Usually, a through hole is provided in one of the two and a screw hole is provided in the other, and a screw is inserted through the through hole and screwed into the screw hole, thereby connecting the two.

[Problems to be solved] According to the above-mentioned conventional technology, since screws must be used, the number of parts increases, leading to an increase in cost, and the assembly work becomes extremely complicated, resulting in high cost. There are inconveniences such as losing the .

Therefore, the purpose of the present invention is to provide a watch frame structure that allows the two to be easily connected with one touch, makes it easy to separate the two, and reduces costs without requiring extra parts. It is in.

[Means for Solving the Problems] In order to achieve the above object, the frame structure of the present invention includes a frame body having a flange portion at the rear end portion, and a rear end surface that contacts the flange portion so that the outside of the frame body It consists of an outer frame that fits into the The frame body is provided with an elastic locking arm on the peripheral wall, and the elastic locking arm has a pair of locking protrusions at its rear end, and a height lower than the locking protrusion between the two locking protrusions. It is equipped with a removal protrusion.
The collar portion is provided with a through hole at a position opposite to the removal protrusion into which the tip of the removal tool can be inserted. Further, the outer frame is provided with a locking groove into which the locking protrusion is locked, and a groove at a position opposite to the through hole that guides the tip of the removal tool to the position of the removal protrusion.

[Operation] With such a configuration, when the outer frame is fitted to the outside of the frame body, the locking projections lock in the locking grooves, and the two are irremovably connected. When the tip of the removal tool is inserted through the through hole, it is guided by the groove and reaches the removal protrusion. Then, when the removal tool is slightly swung, the removal protrusion is pressed downward, the elastic locking arm is elastically deformed, the locking protrusion is disengaged from the locking groove, and the two can be separated.

[Example] An example of the present invention will be described with reference to the drawings.

As shown in FIG. 1, an outer frame 2 is provided on the outside of the frame 1.
are mated.

As shown in the first to third figures, the frame 1 has a collar 11 at its rear end, and its peripheral wall 12 includes:
An elastic locking arm 14 is formed by a U-shaped cut groove 13. At the rear end of the elastic locking arm 14, a pair of locking protrusions 15, 15 are provided with an interval between them. ) height removal protrusion 16 is formed. The rear end surface of this removal protrusion is a tapered surface 16.
It becomes a. A removal protrusion 16 is provided on the flange 11.
A through hole 17 into which the tip of the removal tool 3 can be inserted is provided at a position opposite to the. Reference numeral 18 denotes a locking hole, and with the protrusion of the dial 4 inserted into this hole as shown in the first figure, the locking claw 5a of the front glass 5 is locked in the locking hole 18, and the front glass is closed. Attach 5 to frame 1.

As shown in the first, fourth, and fifth figures, the outer frame 2 has a rear end surface 21 in contact with the flange 11. Furthermore, a locking groove 23 into which the locking protrusions 15, 15 lock is formed in the inner surface of the peripheral wall portion 22. Further, at a position facing the through hole 17, a rear end surface 21 is provided on the inner surface of the peripheral wall portion 22.
A concave groove 24 extending from the to the locking groove 23 is provided. The rear end surface of the locking groove 23 is a tapered surface 23a. The front end 25 of the outer frame 2 engages with the outer periphery of the front glass 5.

With such a structure, when the outer frame 2 is fitted to the outside of the frame body 1, the locking protrusion 15 engages with the tapered surface 2.
3a to gradually bend the elastic locking arm 14 inward, and the locking protrusion 15 gradually moves into the locking groove 23.
As a result, the frame body 1 and the outer frame 2 are irremovably connected. When separating the two, insert the tip of the removal tool 3 through the through hole 17, and the groove 2
4, the tip of the removal tool 3 reaches the removal projection 16. The tip of the removal tool 3 is
Since the tapered surface 16a is slid and pressed inward, the elastic locking arm 14 is deflected inward, and the removal tool 3 rides on the removal protrusion 16. Then, when the removal tool 3 is slightly swung, the removal protrusion 16 is further pressed, the elastic locking arm 14 is further flexed, and the locking protrusion 15 is disengaged from the locking groove 23. As a result, the frame 1 and the outer frame 2 can be separated, and the frame 1 can be separated by being pulled out from the outer frame 2.

[Effects] Since the present invention is configured as explained above, there is no need for separate parts such as screws to connect the frames, which is advantageous in reducing costs. They can be easily connected by simply fitting them together, and they can be separated by simply inserting a removal tool and rocking them slightly, which greatly simplifies the work. can be converted into
