Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a fake leather adhered to the outer surface of a camera.

(Background of the invention) In conventional cameras, pseudo-leather such as a vinyl chloride sheet or a rubber sheet is adhered to the outer surface using a rubber adhesive to improve the design, grip, etc.

However, in such conventional cameras, the curing time of the rubber-based adhesive is generally about 24 hours, and when bonding fake leather to a large area such as the outside of the camera, the curing time is long. is 24
There was a problem that it took more than a few hours and the efficiency of the bonding work was poor.

In particular, for underwater cameras, the water pressure test is performed on the completed housing with the fake leather glued on, so if the water pressure test is performed 24 hours after the adhesive has been applied, the adhesive may be damaged. Since it was not sufficiently cured and the adhesive strength was insufficient, there was a problem in that the fake leather peeled off during the testing process, resulting in a high product defect rate.

Furthermore, in the above-mentioned conventional cameras, gas bubbles are generated in the adhesive due to the gas emitted by the solvent, and the bubbles swell up in the adhesive, making the appearance unattractive. There was a problem that it became stiff. In addition, when pasting films, etc., there are films that have many ventilation holes drilled in them to remove air bubbles, but in such configurations, the ventilation holes are exposed on the surface, which impairs the appearance and has a negative impact on the feel. However, there was a problem in that the required quality could not be maintained.

(Purpose of the invention) The present invention was created by focusing on these conventional problems, and aims to shorten the adhesive curing time and provide a good-looking imitation of a camera. .

(Structure of the invention) In order to achieve the above object, in the present invention, thin linear grooves are provided at intervals over the entire surface of the fake leather to be adhered to the outer surface of the camera. The curing time of the adhesive is reduced by evaporating the solvent through the vent holes, and evaporating the solvent through the vent holes. The appearance of the fake leather is improved by shortening the length and expelling air bubbles inside the adhesive caused by solvent gas etc. through the ventilation holes. It is possible to obtain good appearance quality and exterior without hitting the fingers.Also, since the conduit of the ventilation hole provided in the groove is shortened by the thinner wall, it is possible to provide the ventilation hole in the thicker part. The pipe resistance is lower than that in the case where the pipe is provided, and the solvent can be volatilized more easily.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

1 to 3 show a first embodiment of the present invention in which the present invention is applied to an underwater camera.

As shown in FIG. 1, a back cover 2 is hinged to a housing body 1 of the underwater camera, and the back cover 2 has mounting recesses 2a and 2b formed therein.

A fake leather 3 with a large area is placed in this mounting recess 2a.
Faux leather 4 having a small area can be adhered to each of the mounting recesses 2b.

As shown in FIGS. 2 and 3, a plurality of thin grooves 31, 31... are formed at intervals on the outer surface 3a of the fake leather 3, and ventilation holes are formed along the grooves 31. 32, 32... are drilled regularly at intervals.

The work of gluing the fake leather 3 to the mounting recess 2a of the back cover 2 is performed by applying adhesive to the adhesive surface 3b of the fake leather 3 and pasting the fake leather 3 to the mounting recess 2a.
Adhesive protruding from around the vent hole 32,
This is done by wiping off the adhesive that has protruded from 32 with a solvent.

The work of gluing the fake leather 4 to the mounting recess 2b of the back cover 2 is performed in the same way as the work of gluing the fake leather 3.

In the fake leather 3 of the underwater camera having the above configuration, when the fake leather 3 is adhered to the mounting recess 2a of the back cover 2, the solvent evaporates through the ventilation holes 32, 32...
The adhesive cures quickly, the curing time of the adhesive is shortened, and sufficient adhesive strength can be obtained in a short time.

Therefore, since the adhesive has sufficiently hardened within 24 hours of applying the adhesive, if you perform a water pressure test on the underwater camera 24 hours after applying the adhesive, The fake leather 3 will not peel off during the test process.

Moreover, since the ventilation holes 32, 32, .

Furthermore, the bubbles inside the adhesive caused by solvent gas etc. are expelled to the outside through the ventilation holes 32, 32..., so that the fake leather 3 does not partially bulge. Looks better.

According to the first embodiment, the ventilation holes 32, 32 are formed along the thin grooves 31, 31..., so the ventilation holes 32, 32... are not noticeable.
Looks good.

In the above embodiment, the ventilation holes 32, 32... were provided regularly, but they may be provided irregularly.

(Effects of the invention) According to the imitation leather for a camera according to the invention, since the imitation leather is provided with many ventilation holes over the entire surface, the solvent evaporates through the ventilation holes, so that the adhesive can be quickly applied. The adhesive cures quickly, shortens the curing time of the adhesive, improves adhesive work efficiency, and provides uniform and sufficient adhesive strength over the entire surface of the fake leather.

Furthermore, according to the imitation of the camera according to the present invention,
Air bubbles inside the adhesive caused by solvent gas and the like are expelled to the outside through the ventilation holes, so the fake leather does not bulge in parts and looks better. Furthermore, there are ventilation holes in the linear grooves, so
The ventilation holes are not noticeable and do not hit your fingers, making it possible to obtain good appearance quality and exterior.
Since the conduit of the vent provided in the groove is shortened by the thickness, the conduit resistance is lower than in the case where the vent is provided in the thick wall, and the solvent is more easily volatilized.
