Description

[Detailed Description of the Invention] The present invention relates to a structure on the watch side that has a rotating glass edge such as a register ring and a protective lid that covers the glass edge.

Conventionally, when a wristwatch is used for sports, a rotating glass edge such as a register ring is sometimes provided to provide a time setting function.

Wristwatches with such rotating glass edges are often used for strenuous sports such as diving and mountain climbing, and during use, unexpected shocks and vibrations from vigorous exercise often act on the outer periphery of the watch. It was. If an impact is applied to the outer periphery of the watch, the rotating glass edge may rotate and the set time may change, or the outer periphery may be scratched or deformed.
The rotating glass edge could no longer be rotated, or the appearance would be impaired.

In view of the above-mentioned drawbacks of the conventional example, the present invention provides a lid for protecting the rotating glass edge without adding any special locking parts, and realizes an exterior having a rotating glass edge with a lid. The purpose is to Embodiments of the present invention will be described below based on the drawings. FIG. 1 is a sectional view of a main part showing a first embodiment of the present invention.

1 is a body, which has an annular stepped portion 1a on the upper outer periphery;
Also, a rising portion 1b rising from this stepped portion 1a,
It also has an inwardly protruding part 1c that protrudes inwardly from this raised part 1b and on which the glass 2 is placed.

Reference numeral 3 designates a ring-shaped rotating glass edge that is rotatably attached by fitting an annular protrusion 3a into a groove 1d provided on the periphery of the rising portion 1b of the body 1. A scale is marked on the top surface.

4 is a protective lid that covers the watch surface, and is attached to the case 1 with a hinge or the like so that it can be opened and closed.

Reference numeral 5 designates a ring-shaped spring disposed on the stepped portion 1a of the body 1, which imparts appropriate elasticity to the rotating glass edge 3 and moderates its rotating motion.

As shown in FIG. 2, this spring 5 includes a rotation suppressing spring part 5a that pushes up the rotating glass edge 3 from its bottom side, and a locking spring part 5b that protrudes upward from the outside of the watch side and is bent. is provided.

A groove portion 4a provided on the inner circumference of the edge of the protective lid 4 is set to lock onto the locking spring portion 5b, and prevents the protective lid 4 from lifting up. In this first embodiment, when the protective lid 4 is closed as described above, the groove 4a of the protective lid 4 is
The curved surface part of the locking spring part 5b of the spring 5 is fitted into the inside to prevent it from opening due to impact or the like, and when the protective cover 4 is opened, it is configured to have an appropriate click action.

FIG. 3 is a sectional view of a main part showing a second embodiment of the present invention. Note that the same parts as in the first embodiment shown in FIG. 1 are given the same reference numerals.

The locking spring portion 5b of the spring 5 in this embodiment is as follows:
As shown in the figure, it is bent to form an inverted U shape. On the other hand, the groove 4 on the inner side of the periphery of the protective lid 4
A horizontal hole 4b is provided at the bottom of a, and a push button 6 is loosely fitted into this horizontal hole 4b.

As shown in FIG. 3, when the protective lid 4 is closed, a spring portion 5b is engaged with the inner wall of the groove 4a of the protective lid 4.
The protective lid 4 is prevented from opening by engaging the ends of the protective lid 4. At this time, the locking spring portion 5b that presses the push button and comes into contact with one end of the push button 6
When the locking spring portion 5b is bent, the engagement state between the locking spring portion 5b and the groove portion 4a of the protective lid 4 is released, and the protective lid 4 can be opened.

FIG. 4 is a sectional view of main parts showing a third embodiment of the present invention. Note that the same parts as in the first embodiment shown in FIG. 1 are given the same reference numerals.

The locking spring portion 5b of the spring 5 in this embodiment is as follows:
As shown in FIG. 5, it is composed of an inverted U-shaped curved portion 5c and an operating portion 5d.

On the other hand, the edge of the protective lid 4 is provided with a notch 4c.

In this embodiment, when the protective lid 4 is closed, the inner wall 4d (FIG. 6) of the groove 4a of the protective lid 4 engages with the shoulder 5e of the curved portion 5c of the spring 5, and the protective lid 4 is opened. prevent something.

Further, when opening the protective lid 4, the operating portion 5d of the spring 5 is pressed to release the engagement between the shoulder portion 5e of the curved portion 5c and the inner wall 4d of the groove portion 4a. Become.

FIG. 7 is a sectional view of a main part showing a fourth embodiment of the present invention. Note that the same parts as in the first and second embodiments shown in FIGS. 1 and 3 are given the same reference numerals.

The locking spring portion 5b of the spring 5 in this embodiment is provided with a horizontally long cut portion 5f, as shown in FIG. On the other hand, a long hole 4d is provided at the periphery of the protective lid 4.
A slide button 7 is loosely fitted into this elongated hole 4d.

In this embodiment, when locking the protective lid 4 in a closed state, after closing the protective lid 4, slide the slide button 7 so that its tip 7a fits into the notch 5f of the locking spring portion 5b. It is meant to be. When opening the protective lid 4, slide the slide button 7 and press the tip 7a.
It is configured to release the locked state and open by letting the locking spring portion 5b out of the notch 5f of the locking spring portion 5b. FIG. 9 is a sectional view of a main part showing a fifth embodiment of the present invention.

Note that the same parts as in the first embodiment shown in FIG. 1 are given the same reference numerals.

The protective lid 4 in this embodiment basically consists of the first
Similarly to the embodiment, the locking spring portion 5b of the spring 5 is fitted into the groove portion 4a of the protective lid 4 due to the elasticity of the spring, thereby preventing the protective lid 4 from floating.

However, the protective lid 4 in this embodiment is provided with an elongated hole 4e on its upper surface, and this elongated hole 4
A slide button 8 that slides inside e is attached. This slide button 8 usually has a spring 5
It is located in a place that does not come into contact with the locking spring part 5b, and by sliding it, the tip part 8
a pushes the locking spring portion 5b outward, that is, toward the inside of the protective lid 4a.

When the locking spring portion 5b is pressed by the slide button 8 in this way, the locking spring portion 5b cannot bend inward toward the watch side as when opening the protective cover 4, and the protective cover 4 will be locked in the closed position.

According to the present invention, when attaching a protective cover to a watch having a rotating glass edge, the rotating glass edge can be attached without adding a spring for a click operation or a spring for a locking mechanism when opening and closing the protective cover. The number of parts can be kept to a minimum by using the spring as one unit.

In addition, assembly and manufacturing are easy because no small springs are used.

As described above, the present invention relates to a watch with a lid that has remarkable practical effects.
