Definitions
- the present invention relates to a watch case, and particularly to a watch case having an impact-resistant structure for protecting a movement (including a module) in the case.
- a shock-resistant structure for protecting a movement accommodated in a watch case from an externally applied shock for example, a watch case described in Japanese Utility Model Publication No. 6-11710 is known. .
- Fig. 47 is a cross-sectional view showing a wristwatch case according to the prior art.
- a buffer 3 made of an elastic material is provided.
- the buffer 3 is sandwiched between the inner shell 1 and the outer shell 2 so as to cover the upper surface 1 a of the inner shell 1 and the outer periphery of the annular projection 1 b holding the windshield 4.
- the inner trunk 1 and the outer trunk 2 are fixed by a plurality of fixing screws 5.
- the metal back cover 7 is fixed to the inner body 1 by screws 8.
- This shock-resistant structure has the advantage that the shock applied to the watch case can be absorbed by the elastic deformation of the shock absorber 3 and the seeds transmitted to the movement 6 can be reduced.
- FIG. 48 is a cross section in the case where a screw lock crown is employed in the above-described conventional technology.
- the screw lock crown is composed of a support cylinder 17 fixed to the hole 16a of the inner body 1, a crown head 10 supported and screwed to the thread of the support cylinder 17 with screws 18, and
- the winding stem 11 includes a winding stem connecting member 13 that is connected to the winding stem 11 with screws 12 and is rotatably supported by the support cylinder 17, and a retaining ring 9 that is fitted to the winding stem 13.
- the coil split The head 10 protrudes outward by the ring 14, and the engaging hole 15 having a polygonal cross section of the inner wall of the head engages with the corresponding polygonal engaging portion 16 of the outer wall of the winding connection member 13.
- the winding pin 11 can be rotated via the connecting member 13 to adjust the time.
- a crown guard 19 is often used to protect the crown from impact.
- the crown guard 19 is composed of a pair of protective walls protruding from the outer shell 2 so as to sandwich the crown head 10 from both sides.
- the size of the crown guard 19 is formed to be larger than the crown head 10 in both height and length so that no impact is applied to the crown head 10. This crown guard 19 prevents shock from being applied to the crown head 10. Thus, it is possible to prevent an accident in which the winding pin connected to the crown is bent or broken by an impact.
- the outer peripheral wall 1c of the inner shell 1 and the inner peripheral wall 2a of the outer shell 2 are completely in close contact with each other at the portion where the shock absorber is not arranged. Seeds hit on the inner trunk 1 are easily transmitted to the inner trunk 1. In addition, an impact applied to the outer shell 2 from the outside is transmitted to the inner shell 1 via the fixing screw 5.
- the impact is transmitted to the movement 6 contained in the inner body, and the movement 6 may be broken.
- the lower surface of the inner trunk 1 is not covered by the buffer or the outer trunk. Therefore, if the wristwatch is dropped and an impact is applied to the lower surface of the inner body, the impact cannot be buffered at all.
- the outer trunk 2 covers the upper side surface of the inner trunk 1, but the lower surface of the inner trunk does not. Therefore, when the screw 8 is loosened, the inner trunk may come off from the outer trunk.
- the outer shell 2 in the above-mentioned impact-resistant structure is a synthetic resin, although hard, but does not have sufficient strength, scratch resistance and abrasion resistance. Therefore, when an excessive impact is applied to the wristwatch, the outer shell made of hard synthetic resin may crack even if the shock absorber sandwiched between the body and the outer shell can be elastically deformed. Also, if you use the watch for a long time, the outer body will be damaged or worn.
- the crown guard 19 is larger than the crown head 10, it prevents a finger from touching the crown head 10. Therefore, it is difficult to rotate the crown head 10 with a finger.
- a first object of the present invention is to provide an impact-resistant structure of a wristwatch case that can sufficiently absorb an impact.
- a second object of the present invention is to provide an impact-resistant structure of a wristwatch case that can securely fix an outer case and an inner case.
- a third object of the present invention is to provide an impact-resistant structure for a watch case having sufficient strength, scratch resistance, and wear resistance.

- the primary molding die is removed, the secondary molding die is attached, and the inner shell is placed in the secondary molding die.
- a soft synthetic resin such as polyurethane is injected into the secondary molding die.
- the outer surface of the inner shell made of the hard synthetic resin and the injected soft synthetic resin are integrally cured.
- the outer shell made of the soft synthetic resin is integrally formed outside the inner shell made of the hard synthetic resin.
- the inner and outer shells may be integrally formed using the insert molding method.
- the outer shell 122 is disposed so as to cover the upper, side, and lower surfaces of the inner shell so that the inner shell 123 is not exposed to the outside.
- a pair of connecting legs 125 for connecting the knobs 124 are formed on both sides of the outer shell 122.
- connection hole into which a connection pin 126 for connecting the band 124 is inserted is formed in a contour 123 of the outer body, whereby the band is connected to a rigid inner contour.
- the band pulling force does not reach the soft outer shell, so that the danger of the outer shell being deformed or broken can be prevented. Also, even if the band is pulled, the rigid inner shell does not deform or break, so that the band is firmly connected to the outer shell.
- the inner body 120 includes a main body 120a and a bottom 120b as shown in FIGS.
- a movement 130 is arranged on the bottom part 120 b through an annular bottom buffer body 127 made of synthetic resin and an anti-magnetic member 13 1, and is provided with an outer periphery of the anti-magnetic member 13 1.

- the movement cushion 1336 has a downward step 1336a, with which the dial fixing part 134 of the movement is engaged.
- the return ring buffer 1 3 8 is a windshield receiving member due to the impact applied to the windshield 1 4 5 This prevents the 140 from hitting the dial ring 13 7 and damaging any of them, and also prevents the windshield itself from being damaged. Further, the impact on the windshield 1 45 is prevented from being transmitted to the movement 130.
- the dial ring 1337 has upper and lower extensions 1337a and 1337b (Fig. 27), and hides the buffers 138 and 136, especially the extension 1337a. Is extended to the place of the windshield receiving member 140 so that the buffer is not visible from the outside. Further, even if a radial impact is applied, the extension portion 1337a hits the cushioning member 1338 ', so that damage to the ring can be prevented.
- the movement buffer 1 36 prevents the axial impact from being transmitted to the movement 130 and also prevents the dial ring 1 37 from hitting the movement. Furthermore, the dial contacts the upper surface of the outer periphery of the dial 135 to suppress the dial.
- the cylindrical buffer body 132 absorbs external force applied to the outer shell 122 and the inner shell 120 to prevent it from being transmitted to the movement.
