Abstract

PURPOSE:To make it possible to the water-proof attachment of a photograph, a decorative plate or the like, by a method wherein an opening part is provided to the central part of the bottom surface of a back lid to be inlaid with a plate made of synthetic resin, ceramics or the like and a water-proof packing is arranged between the opening part and the plate. CONSTITUTION:To the upper end of the outer peripheral rising part of a bottomed dish shaped core 3, a flange part projected to the outer periphery is provided and an engaging protrusion 3a is formed from a part of said flange. A large opening part 2A is formed to the central part of the back lid 2 and, in the outer peripheral part thereof, a core 3 is adhered to the bottom surface of said lid by welding or soldering. A photograph 9 or the like is arranged in the opening part of the back lid and pressed from the upper surface thereof by glass 4. A plastic packing having intermediate hardness is contacted with the outer peripheries of the opening part 2A and the glass 4 and develops function for fixing the glass and, at the same time, the water-proofness to the interior of the glass. By this method, a decorative element can be added to a portable watch in addition of water-proofness.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for attaching KfilC decorative plates, mirrors, photographs, etc. of wristwatches and pendant watches.

Traditionally, the above-mentioned structures have not been seen in the market, such as cases where a line is drawn directly on the case back, as seen on hand watches,
All I could see were pendants, so-called lockets, other than watches, which had been pasted with printed resin films and had been torn to pieces, with photographs inlaid into them. The creators of this invention had no idea how to attach it to the back of a wristwatch, let alone to make it waterproof.

In addition to the above, the present invention provides a waterproof, inexpensive, and simple practical structure for parts that are exposed to sweat and rainwater.

Figure 1 shows the structure of a traditional clock with a picture on it, A
It is difficult to draw a picture on some parts due to paint. Usually they are hand-painted, but I have not seen any inexpensive ones that have printed Zawa L resin film glued on them. The W2 diagram is the same (conventional rocket). Place the glass 25 on the edge of photo 24 and press the glass presser 11.
This structure is such that the ring 22 is pushed into the shell 21 and assembled. This is very simple, but since no consideration was given to waterproofing, it could easily be applied to wristwatches and the like.

In Fig. 3, 6 is a saucer-shaped core with a bottom, and has a flange portion projecting to the outer periphery at the upper end of a rising portion of the outer periphery, and a retaining protrusion 3a is formed from a part of the flange. There is. 2 is a camera back with a wide opening 2A in the center.
2. At its outer periphery, n9, which is joined to the bottom surface of the core 3 by welding or brazing, is a photograph or printed matter, placed in the opening of the back cover, and pressed from the top with the glass 4. ing. , 6 is a plastic gasket having medium hardness such as Tefzel or polyethylene, which is located on the back cover opening 2A and the outer periphery of the glass 4, and serves to fix the glass and at the same time waterproof the interior of the glass. The back cover 1 with the photograph or printed matter 9f set in the above manner is inserted into the engagement protrusion 2a of the back cover into the engagement groove 1A provided on the inner wall of the body.
And back cover Patsukin 8? It is removably engaged with the body through the body.

, Attach the body 1 through the glass gasket 8'fr with the 5-piece windshield.
It is fixedly offset. , is a middle frame that supports the 12-digit movement 10, and 11 is a screw for operating the movement 10 from the outside.

The three people in the figure have through-holes for removing the glass 4 when it is necessary to replace the photograph or printed matter 9. The printed matter can be incorporated into the cover of a mobile watch in an extremely wasteful and waterproof manner. Nowadays, as a portable watch, pendants are most commonly used, but other uses are also possible.

In place of the photograph, leaves of trees, butterfly wings, or holograms can be held in place, and in place of the glass 4, ceramics, tiles, metal plates, various bonded materials, etc. can be used as decorative plates or mirrors. is almost similar to the embodiment shown in FIG. 6, but the insertion direction of photographs and printed matter is different from that shown in FIG.

5- The v4 diagram will be explained below. In Fig. 4, there is a flange core with a 6-square cross section, and a glass 4. The difference in thickness from Fig. 3 is that the opening 3B is slightly smaller.The glass 4 is fixed by pushing it into the back cover 2 through the plastic gasket 6 before inserting the photograph or printed matter 9F. After that, the photograph or printed matter 9 is inserted from the direction of the opening 3B of the core. ,1
Reference numeral 3 denotes an internal member made of synthetic resin or metal, which is used to bring the photograph 9 into close contact with the glass 4. The inner cover 15 is conditioned to be fixed by pushing it into the opening 3B of the core with a tightening margin.In addition, in order to remove the inner cover from the opening 3B of the core, one or more removal grooves 13A are provided. It was possible to easily add more decorative elements to a functionally oriented mobile watch.
