Description

[Detailed Description of the Invention] The present invention relates to a frame fixing structure for a watch case, and more particularly to a watch case in which a front member, a side member, and a top member are integrated, and a watch case including a front member, a side member, and a top member of the watch case. The frame body fixed to the corner of the frame body can be securely fixed with one touch without using adhesive or the like.

Among conventional watch cases, for example, there is a transparent case for a decorative table clock in which parts of the watch case other than the time display section are made transparent so that the user can visually see the watch wheel train structure from outside the watch case.

Among such transparent cases, there is one in which a front member, a side member, and a top member are integrally molded from transparent plastic. In such cases, adhesives have been used to fix the folding frame to the corners.

However, in such watch cases, the parts other than the time display are transparent, so the adhesive can be seen through the case, and for this reason, fixing the frame with adhesive will seriously spoil the appearance of the watch as a decorative watch. I was getting used to it.

The present invention is an attempt to solve these conventional problems, and its purpose is to apply one-touch adhesives to the corners of a watch case where the front, side, and top members are integrated, without using adhesive. To provide a frame body fixing structure for a watch case that can securely fix the frame body.

In order to achieve the above object, the present invention provides a watch case in which a front member, a side member, and a top member are integrated, and a frame fixed to a corner of the front member, side member, and top member of the watch case. At least one protrusion or recess is formed on the frame portion that contacts the top member of the watch case, a plurality of claws are formed on the frame portion that contacts the side member, and the frame portion that contacts the front member is formed with at least one protrusion or depression. A plurality of convex portions or concave portions are formed on the body portion, while a concavity or protrusion is formed at the position of the watch case front member corresponding to the protrusion or concavity of the frame, and a watch case side member corresponding to the tab of the frame. A groove is formed at the position to slidably accommodate the tab of the frame body, and a groove is formed at the position of the watch case front member corresponding to the convex part or concave part of the frame body to slidably engage with the convex part or concave part of the frame body. Forming a concave part or a convex part,
A notch is formed in the groove formed at the position of the side member of the watch case corresponding to the tab of the frame body so that the tab of the frame body can be inserted from the direction of the front member. It is characterized in that by sliding the body in a direction opposite to the upper surface member, a recess or protrusion formed on the upper surface member and a protrusion or recess formed on the frame are engaged with each other.

Embodiments of the present invention will be described below based on the drawings.

1 and 2, a watch case 10 includes a front member 12, left and right side members 14, 16, and a top member 18 that are integrally molded from transparent plastic.

On the other hand, a decorative frame 20 serving as a frame has a protrusion 29 formed at a position where it contacts the upper surface member 18 of the watch case 10, and the left and right side members 1 of the watch case 10.
There are claws 25 at the positions where they contact 4 and 16, respectively.
a, 25b, 27a, and 27b are formed, and convex portions 23a and 23b are formed on the left and right, respectively, at positions that contact the front member 12 of the watch case 10.

A recess 19 is formed at the position of the upper surface member 18 of the watch case 10 corresponding to the decorative frame 20 and the protrusion 29, and furthermore, a recess 19 is formed at the position of the left side member 14 corresponding to the claws 25a, 25b of the decorative frame 20.
A groove 15 is formed to slidably accommodate the tabs 27a and 27b, and a groove 17 is formed at a position of the right side member 16 corresponding to the tabs 27a and 27b. The grooves 15 and 17 formed in the left and right side members 14 and 16 are provided with claws 25 of the decorative frame 20, respectively.
a, 25b, 27a, 27b can be inserted from the direction of the front member 12 shown by the arrow E, a notch 15a,
15b, 17a, and 17b are formed. Furthermore, recesses 13a and 13b are formed at positions on the front member 12 corresponding to the projections 23a and 23b of the decorative frame 20, and are slidably engaged with the projections 23a and 23b.

The watch case in this embodiment has the structure as described above, and a method for assembling it will be explained next.

In FIG. 3a, a decorative frame 20 indicated by a two-dot chain line
In this position, the decorative frame 20 is coupled to the watch case 10 from the direction of the seal E. This connection connects the claws 27a and 27b of the decorative frame 20 to the notches 17a and 17 formed in the groove 17 of the watch case 10, respectively.
b, and by inserting the convex portion 23b of the decorative frame 20 into the concave portion 13b of the watch case 10. In this state, the protrusion 2 of the decorative frame 20
The portion 9 is located at the position indicated by the two-dot chain line in FIG. 3b.

From this state, the decorative frame 20 is slid in the direction of arrow F as shown in FIG. 3a. Due to this sliding, the claws 27a, 27b and the convex portion 23b of the decorative frame 20 move to the positions indicated by solid lines. Due to this movement, the claws 27a and 27b are attached to the watch case 10.
The decorative frame 20 is securely stored in the groove 17 of the watch case 10, and the protrusion 29 of the decorative frame 20 also engages with the recess 19 of the watch case 10, as shown in FIG. .

Although the explanation is omitted, the claw 25 of the decorative frame 20
The connection and insertion of the convex portion 23a and the groove 15 of the watch case 10 and the concave portion 13a are also shown in FIG. 3a.
This process is similar to the process shown in .

The fixation of the watch case 10 and the decorative frame 20 is completed through the steps described above.

FIG. 4 shows an enlarged sectional view taken along the line C--C in FIG. 2.

As is clear in the figure, the claw 2 of the decorative frame 20
5b is securely accommodated in the groove 15 of the watch case 10, and this accommodation completely prevents the decorative frame 20 from coming off in the direction of arrow G.

FIG. 5 shows an enlarged sectional view taken along line D--D in FIG. 2.

In the figure, the convex portion 23b of the decorative frame 20 is reliably engaged with the concave portion 13b of the watch case 10, and this engagement completely prevents the decorative frame 20 from deforming in the direction of arrow H.

In this embodiment, a depression is formed on the top member of the watch case, and a protrusion is formed on the decorative frame.
It is also possible to form a depression in the decorative frame.

Furthermore, although a concave portion is formed on the front member of the watch case and a convex portion is formed on the decorative frame, it is also possible to form a convex portion on the front member of the watch case and a concave portion on the decorative frame. be.

As explained above, according to the present invention, the protrusion or depression formed on the frame can be easily removed by inserting the claw formed on the frame into the notch formed on the side member of the watch case and sliding it inside the groove. engages with a recess or protrusion formed on the watch case top member, and a protrusion or recess formed on the frame engages with a recess or protrusion formed on the watch case front member, so that the watch case on the frame It can be securely fixed with one touch, eliminating the need for adhesives, etc.
