Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a watch side, and more particularly to a watch side having features in a glass fixing means.

(Prior Art) A watch is already known in which at least a part of the periphery of the glass forms the contour of the watch side.
Several proposals have been made regarding glass fixing means for this type of watch.

What was disclosed in Japanese Patent Application Laid-open No. 58-33175 is
This type of glass is inserted from the side into a sliding groove provided in the body, but as pointed out in Japanese Patent Application Laid-open No. 57-211577, etc., this type of glass is There is a risk that the packing may be deteriorated or deformed due to directional movement.

In order to solve this problem, the latter method moves the glass horizontally to position it before tightening the bottom, and then presses the glass onto the packing while tightening the bottom to the body. However, there is a risk that the flexible and thin packing may be deformed when the glass moves in the horizontal direction. Glass is press-fitted while being elastically deformed, and the periphery of the press-fitted glass is held by a shallow inwardly inclined surface of the body. However, if a large impact or negative pressure is applied to the glass, it will easily come off. It has the following problems.

(Purpose) The present invention has been made in view of the above problem, and its purpose is to avoid applying lateral frictional force to the packing that causes deformation, etc., and to prevent stacking errors within the tolerance range. The purpose of the present invention is to provide a watch side with a simple structure that can be assembled without causing problems.

(Structure) That is, the present invention integrally forms a protruding step portion for attaching a glass fixing member to a watch body whose upper surface is a glass mounting surface, and presses the upper edge of the glass inward to the step portion. A glass fixing member having a supporting protrusion and a connecting part with a band on the outside is placed on the glass fixing member, and is integrally tightened and fixed with screws together with the case back which is in contact with the lower surface of the watch body. The feature is on the watch side.

Therefore, details of the present invention will be explained below based on illustrated embodiments.

FIG. 1 shows an embodiment of the present invention, and the reference numeral 1 in the figure is a watch body whose upper surface 2 is a mounting surface for a glass 3 and the inside is a movement housing, and the outer periphery is the plane of the glass 3. This watch body 1, which is formed to have the same shape, has a pair of glass fixing members 5, which will be described later, on the 12 o'clock side and the 6 o'clock side, that is, on the side where the band is attached.
A plate-shaped bracket 4 for placing and fixing the is integrally formed in a protruding manner.

By the way, this glass fixing member 5 is a member that serves both to connect the band and to fix the glass 3, and has a supporting protrusion 6 on its inner upper part that presses and supports the upper edge of the glass, and on its outer lower part. It has a concave part 7 for fixing the band end, and is configured to be integrally tightened and fixed on the bracket 4 with screws 9 together with a back cover 8 that is joined to the lower surface of the watch body 1. There is. In addition, the reference numeral 10 in the figure indicates the clock body 1.
It shows the packing fitted around the top surface.

Therefore, in order to assemble a watch constructed in this way, first, the glass 3 is placed on the top surface 2 of the watch body 1 via the packing 10, and then the supporting protrusion 6 is attached to the upper edge of the glass 3. After the pair of glass fixing members 5, 5 are placed on the bracket 4 of the watch body 1 so as to be in contact with each other, they are fixed together with the back cover 8 by tightening with screws 9. As a result, the glass fixing member 5 is subjected to the tightening action of the screw 9 and presses the glass 3 onto the watch body 1 by means of its support protrusion 6.

FIG. 4 shows another embodiment of the present invention applied to a pendant timepiece, in which an engaging recess 12 that engages with one end edge of a glass 13 is formed protruding inwardly on the upper surface of the watch body 11 on the 6 o'clock side. On the other hand, on the 12 o'clock side, a plate-shaped bracket 14 is integrally formed to protrude, and a chain connection block 15 having a glass support protrusion 16 formed on the inner surface is placed here, and together with the back cover 18. screw 1
9, and the reference numeral 17 in the figure indicates a ring for attaching the chain.

In this embodiment, one end edge of the glass 13 is fitted into an engagement recess 12 protruding from the 6 o'clock side of the watch body 11,
It is sufficient to fix the other end edge with the block 15 for chain connection, and by tightening the screw 19, the glass 13 is fixed using the upper inner surface of the engagement recess 12 as a fulcrum.
The 12 o'clock side is pressed down by a support protrusion 16 to be tightly fixed onto the watch body 11.

(Effects) As described above, according to the present invention, the glass is placed on the top surface of the watch body and is fixed by pressing it from above using a glass fixing member separate from the watch body. To airtightly fix glass to the upper surface of a watch body without deforming a flexible and thin glass packing. Moreover, this glass fixing member, which also serves as the end joint of the bands, and the case back, which covers the lower opening of the watch body, are attached to a common bracket that protrudes from the outer surface of the watch case. Since they are integrally tightened and fixed using screws inserted from the side, not only can assembly be extremely simplified, but even if there are variations in the tolerance range of these,
The glass and the back cover can be airtightly assembled without causing stacking errors and with sufficient waterproofness essential for a portable watch.
