DETAILED DESCRIPTION

[0017] Below, refer to Figure 1 to Figure 2 A timepiece 1 according to a first embodiment of the present invention will be described. Figure 1 It is a top view of the timepiece 1 according to the first embodiment. Figure 2 1 is a cross-sectional view showing a part of the clock 1. In the present embodiment, as an example, an example of applying the device to the dial of the clock 1 is shown. In the figure, X, Y, and Z respectively represent three directions that are orthogonal to each other. For example, in the present embodiment, with respect to the clock 1, the posture along the first direction of the Z axis along the back direction of the clock 1, the X axis along the longitudinal direction connecting the 6 o'clock and 12 o'clock of the clock 1, and the Y axis along the horizontal direction connecting the 3 o'clock and 9 o'clock of the clock 1 is described as an example, but it is not limited to this.

[0018] As Figure 1 and 2 The device shown in the clock 1 is, for example, a wristwatch, and includes a clock case 11 constituting an outer shell, a clock module 12 disposed in the clock case 11, a transparent cover 13 covering one side in a first direction, i.e., the front side, of the clock module 12, and a back cover (not shown) covering the other side in the first direction, i.e., the back side, of the clock module 12. In addition, the clock 1 includes a strap 14 connected to two locations of the outer periphery of the clock case 11, and a plurality of switches disposed on the outer periphery of the clock case 11.

[0019] The watch case 11 includes a frame 20 disposed on the outer periphery of the watch module 12. The watch case 11 includes band attachment portions for attaching the band 14 at two mutually opposing locations on the outer periphery, for example, at 6 o'clock and 12 o'clock of the watch.

[0020] The frame 20 is provided with a peripheral wall portion 21 formed of a metal or resin material, covering the outer periphery of the watch module 12 and the cover 13, and a storage portion 15 is formed in the central portion to form a space for configuring the watch module 12 and the cover 13. In the present embodiment, the frame 20 and the storage portion 15 are formed in a rectangular shape. That is, the frame 20 is configured as a quadrilateral shape surrounded by two sides extending in the horizontal direction along the X-axis and two sides extending in the longitudinal direction along the Y-axis. For example, in the present embodiment, the inside-outside direction of the watch case 11 becomes a direction orthogonal to the circumferential direction and the table back direction, for example, the inside-outside direction is the horizontal direction in the longitudinal side, and the inside-outside direction is the longitudinal direction in the lateral side. In addition, when the watch case 11 is circular, the shape of the frame 20 and the storage portion 15 is also formed in a circular shape.

[0021] The peripheral wall portion 21 has a protruding wall portion 22 that protrudes in the inner peripheral direction over the entire circumference. In addition, the frame body 20 may be configured by combining a plurality of case members.

[0022] The storage section 15 is a recessed portion in which the watch module 12 and the cover 13 are disposed. The storage section 15 is a space opened on the front side and the back side. For example, in the housing 20, the front side of the opening constituting the storage section 15 is covered by the cover 13, and the back side is covered by a back cover.

[0023] As an example, the housing 15 of the watch case 11 includes a first housing 15a where the cover 13 is disposed and a second housing 15b where the watch module 12 is disposed on the back side of the first housing 15a. A protruding wall 22 is disposed between the first housing 15a and the second housing 15b where a portion of the inner peripheral surface of the frame 20 protrudes inward.

[0024] A plurality of steps are formed on the inner circumference of the frame 20 in accordance with the arrangement of the parts. For example, the surface of the frame 20 has a first inner circumference 21a facing the outer circumference of the watch module 12, a back edge surface 21b which is the back of the protruding wall 22 and arranged on the front side of the outer circumference of the watch module 12, a front edge surface 21c which is the surface of the protruding wall 22 and facing the back side of the periphery of the cover 13, a second inner circumference 21d facing the outer circumference of the cover 13, an outer surface 21e, and a back surface.

[0025] That is, in the watch case 11, the watch module support portion is formed by the first inner circumferential surface 21a forming the second storage portion 15b and the back side of the protruding wall portion 22, i.e., the back edge surface 21b, and the cover support portion is formed by the surface of the protruding wall portion 22, i.e., the surface edge surface 21c and the second inner circumferential surface 21d constituting the first storage portion 15a.

[0026] The first inner peripheral surface 21 a is an inner wall surface provided upright along the first direction, and is arranged to face the outer side of the outer peripheral portion of the timepiece module 12 .

[0027] The back edge surface 21b is the back side of the protruding wall portion that is continuous from the front side end of the first inner peripheral surface 21a and extends radially inward, and forms a plane that is orthogonal to the thickness direction of the timepiece 1, that is, the first direction. The back edge surface 21b is arranged opposite to the surface of the peripheral edge of the timepiece module 12. For example, the back edge surface 21b of the protruding wall portion 22 serves as a restraining portion that restricts the position of the timepiece module 12 in the first direction. The back edge surface 21b of the protruding wall portion 22 may also have a step or a concave-convex corresponding to the opposing component.

[0028] The front edge surface 21c is arranged to face the peripheral edge of the back surface of the cover 13. The outer peripheral edge of the front edge surface 21c is arranged outside the outer peripheral edge of the back edge surface 21b.

[0029] The surface edge surface 21c has: a bottom support portion 21f, which supports the back side of the peripheral portion of the cover 13; a retreat recess 21g, which retreats toward the back side on the inner side of the bottom support portion 21f; and a retaining groove portion 21h (first recess), which retreats toward the back side on the outer side of the bottom support portion 21f and is provided with an adhesive.

[0030] The bottom support portion 21f has a bottom surface portion facing the back surface of the cover 13 in an area on the outer peripheral side of the surface of the protruding wall portion 22. The bottom support portion 21f has an upper surface (one surface) located on the front side of the bottom surface of the retreat recess 21g and having a plane portion orthogonal to the first direction, and supports the cover 13 by being in contact with or facing the back surface of the cover 13. For example, the bottom support portion 21f has a plane extending from the base end portion on the back side of the second inner peripheral surface 21d to the inner peripheral side and divided into two by the retaining groove portion 21h. That is, by forming the retaining groove portion 21h on the bottom support portion 21f, the inner and outer areas of the retaining groove portion 21h are respectively disposed facing the back side of the outer peripheral portion of the cover 13 at a position on the front side compared to the bottom surface of the retaining groove portion 21h.

[0031] The retreat recess 21g is formed in the area on the central side of the watch case 11 in the surface of the protruding wall portion 22, forming a bottom surface that is retreated to the back side compared to the bottom support portion 21f. The bottom surface of the retreat recess 21g is arranged with a predetermined gap G1 spaced from the back side of the cover 13. That is, the area on the central side between the surface of the protruding wall portion 22 of the watch case 11 and the back side of the cover 13 is separated in the front-to-back direction, forming a gap G1 surrounded by the bottom support portion 21f all around.

[0032] The retaining groove portion 21h is a circumferential groove that is recessed toward the back side in the area on the outer peripheral side of the bottom support portion 21f, and is continuously formed over the entire circumference of the frame-shaped watch case 11. The retaining groove portion 21h constitutes an adhesive portion that retains the adhesive P and bonds the watch case 11 and the cover 13. Here, the dimension of the depth direction of the retaining groove portion 21h, that is, the first direction (along the Z axis) is shallower than the dimension of the depth direction of the adjacently formed retreat recess 21g. In addition, the dimension of the groove width direction along the inner and outer directions of the retaining groove portion 21h is larger than the dimension of the depth direction along the first direction (along the Z axis).

[0033] In addition, the depth of the holding groove portion 21h may be greater than the depth of the retreat recessed portion 21g. In addition, the depth of the holding groove portion 21h may be greater than the groove width of the holding groove portion 21h.

[0034] The second inner peripheral surface 21d is an inner wall surface erected from the outer peripheral edge of the surface of the protruding wall portion 22 toward the front side along the first direction and is arranged to face the outer side of the outer peripheral portion of the cover 13. For example, the second inner peripheral surface 21d is located outside the first inner peripheral surface 21a.

[0035] The outer surface 21 e extends outward from the front side end portion of the second inner peripheral surface 21 d , and constitutes the front side and outer peripheral side surfaces of the watch case 11 .

[0036] The back surface of the frame 20 is bonded to the back cover by bonding or fastening. For example, a waterproof ring is attached to the back surface of the frame 20 to make the back cover airtight.

[0037] The watch module 12 is stored in the storage section 15 of the frame 20. For example, the watch module 12 is arranged on the back side of the cover 13, and is arranged in the first storage section 15a which is the back area of ​​the storage section 15. For example, the watch module 12 includes a display device that displays various information such as time, and a circuit substrate that is equipped with various electronic components such as an IC as a driving section and an antenna. The watch module 12 also includes a battery, a solar substrate, various sensor components, and various components required for other watch functions. In this embodiment, the stacked display device and the circuit substrate are configured to correspond to the shape of the watch case 11, for example, in a rectangular shape.

[0038] The cover 13 is a transparent component formed of a light-transmitting material such as SiO2 glass. For example, the cover 13 is a rectangular plate-shaped watch glass along the shape of the first storage portion 15, which is arranged on the surface side of the watch module 12 and covers the surface side of the watch module 12. For example, the cover 13 is supported on the inner peripheral edge of the opening on the surface side of the watch case 11. The peripheral surface portion on the back side of the cover 13 is arranged opposite to the bottom support portion 21f having the retaining groove portion 21h, and is bonded to the watch case 11 by the adhesive P supplied to the retaining groove portion 21h. As an example, in the present embodiment, the cover 13 is provided with a gasket between the cover 13 and the frame 20 of the watch case 11, and is bonded to the frame 20 of the watch case 11 by the adhesive P.

[0039] The cover 13 is plate-shaped and has a front surface 13a, a back surface 13b, and an outer peripheral surface 13c. The front surface 13a and the back surface 13b form a plane perpendicular to the axial direction. In addition, the edge between the front surface 13a and the outer peripheral surface 13c forms an inclined surface 13d cut by chamfering.

[0040] A cutout or a retreat groove 13f (second recess) formed along the circumferential direction and extending over the entire circumference is formed at the edge between the back surface 13b and the outer peripheral surface 13c of the cover 13, i.e., the end portion or the corner portion (corner portion) on the back side of the outer peripheral surface 13c. That is, a portion of the back side of the outer peripheral surface 13c of the cover 13 retreats to the inner side of the watch case 11 than the area on the front side.

[0041] For example, the outer peripheral surface 13c of the cover 13 continuously includes the first peripheral surface 113a on the front side, the second peripheral surface 113b retreating inward from the first peripheral surface 113a, and the top 113c connecting the first peripheral surface 113a and the second peripheral surface 113b. That is, the retreat groove 13f is formed by the second peripheral surface 113b which is a longitudinal surface facing the inner surface of the peripheral wall of the storage portion 15 with a gap therebetween, and the top 113c which is obliquely facing the bottom surface of the housing 11.

[0042] The first peripheral surface portion 113 a is disposed along the second inner peripheral surface 21 d of the frame body 20 so as to face the second inner peripheral surface 21 d .

[0043] The second peripheral surface 113b (vertical surface) is spaced apart from and faces the second inner peripheral surface 21d with a predetermined gap G2 therebetween. That is, the second peripheral surface 113b is arranged at a position retreated inward from the first peripheral surface 113a.

[0044] The top portion 113c connects the first circumferential surface portion 113a and the second circumferential surface portion 113b. The top portion is inclined relative to the front-back direction and the inside-outside direction. For example, the top portion has a tapered inclined surface extending from the two circumferential surface portions 113b toward the outside and the front side.

[0045] For example, the cover 13 is configured such that the area of ​​a cross section perpendicular to the first direction cut at the second peripheral surface portion 113 b is smaller than the area of ​​a cross section perpendicular to the first direction cut at the first peripheral surface portion 113 a .

[0046] The first peripheral surface portion 113a and the second peripheral surface portion 113b have surfaces parallel to each other. For example, the peripheral surface portions 113a and 113b each have two sets of vertical and horizontal plane portions.

[0047] When viewed in section, the retreat groove portion 13f is configured to be a trapezoidal shape having an inclined edge on the front side. The retreat groove portion 13f is configured to be separated from the retaining groove portion 21h in which the adhesive is configured, sandwiching a portion of the bottom support portion 21f. That is, the retreat groove portion 13f is configured to be separated from the outer peripheral side of the watch case 11 relative to the retaining groove portion 21h. The retreat groove portion 13f is configured such that the dimension Lz along the first direction along the front and back directions is larger than the dimension Lx in the inside-outside direction orthogonal to the first direction and the circumferential direction. That is, the dimension in the groove width direction along the first direction is larger than the depth direction of the groove along the inside-outside direction. The retreat groove portion 13f becomes a retreat portion (adhesive retreat structure) for the remaining portion of the adhesive P configured in the retaining groove portion 21h to enter.

[0048] At least one of the first recessed portion, i.e., the holding groove portion 21h, or the second recessed portion, i.e., the escape groove portion 13f, holds the adhesive. In addition, at least one of the holding groove portion 21h or the escape groove portion 13f constitutes an adhesive release structure that is received when the adhesive overflows. That is, the timepiece 1 as a device has an adhesive release structure.

[0049] For example, when the remaining part of the adhesive P disposed in the retaining groove portion 21h enters the escape groove portion 13f, the escape groove portion 13f becomes an adhesive release structure. Alternatively, when the remaining part of the adhesive P disposed in the escape groove portion 13f enters the retaining groove portion 21h, the retaining groove portion 21h becomes an adhesive release structure.

[0050] For example, when the cover 13 is formed by molding using resin glass, the retreat groove 13f can be formed without increasing the number of steps by forming a protrusion in the mold when the resin is poured into the mold for molding. In addition, when the cover 13 is made of inorganic glass, the retreat groove 13f can be formed by providing a protrusion or a step on the grinding tool during side grinding.

[0051] The watch band 14 includes a pair of band members connected to two opposing locations on the outer circumference of the watch case 11 , and a fastening mechanism such as a buckle.

[0052] The switch is provided, for example, on the outer periphery of the housing, and is pressed by an operator to switch the mode of the timepiece module 12 , adjust the time, and the like.

[0053] The watch case 11 and the cover 13 configured as described above are bonded and fixed to the cover 13 by the adhesive P arranged in the holding groove portion 21 h.

[0054] For example, in the assembly process of the timepiece 1 , adhesive P is applied to the retaining groove 21 h formed on the outer peripheral side of the bottom surface of the storage portion 15 of the timepiece case 11 , and the cover 13 is inserted from the front side of the frame 20 of the timepiece case 11 and fixed by bonding.

[0055] As the adhesive P, for example, a silicone-based or polyurethane-based resin that has elasticity and cures under temperature and humidity is used.

[0056] That is, the manufacturing method of the timepiece 1 according to the present embodiment includes: a first step of applying adhesive to the first recessed portion, i.e., the holding groove portion 21h, formed in the bottom surface portion of the housing portion 15 of the case 11 and the lower surface of the cover 13; and a second step of inserting the cover 13 into the housing portion 15 of the case 11 and fixing it by adhesive after the first step. In the second step, the adhesive overflowing from the holding groove portion 21h enters the second recessed portion, i.e., the retreat groove portion 13f, formed in the outer peripheral surface of the cover 13.

[0057] According to the device and timepiece 1 of this embodiment, even if the adhesive P supplied to the retaining groove portion 21h overflows toward the outer peripheral side during the assembly process of the timepiece 1, the adhesive P can be prevented from overflowing toward the outer surface of the shell by entering the retreat groove portion 13f formed on the outer peripheral surface of the cover 13.

[0058] In addition, the retreat groove portion 13f is a structure having a peripheral surface arranged upright toward the front side. For example, compared with the chamfered shape, by lengthening the dimension in the front-back direction, the dimension in the inside-outside direction can be reduced. That is, the volume of the retreat groove can be ensured without damaging the appearance. For example, in the case where a C-chamfer is formed at the corner of the back side of the cover 13, a larger dimension is required on the inside to ensure the volume, which affects the appearance. However, in the above-mentioned present embodiment, by ensuring the dimension in the first direction along the front-back direction, it becomes a shape that is not conspicuous when viewed from the front side.

[0059] When a groove is formed on the inner peripheral surface of the housing side as in the past, it is necessary to perform cutting using a cutting tool. However, for example, when resin glass is used as the cover 13, since the resin flows into the mold for molding, it can be formed by forming a protrusion in the mold without increasing the number of steps. In addition, when inorganic glass is used as the cover 13, a cut shape can be formed in the side grinding that is usually performed, so the first recess can be formed at the same time. Therefore, the retreat portion of the adhesive can be easily formed without increasing the number of steps.

[0060] In addition, the escape groove 13f is not continuous with the holding groove 21h, but is separated therefrom with a part of the bottom support 21f sandwiched therebetween, thereby reducing the volume of the holding groove 21h and reducing the amount of adhesive required, and absorbing the excess adhesive while ensuring the adhesiveness. That is, the excess adhesive P can be absorbed by the escape groove 13f after the adhesive is preferentially spread over the holding groove 21h.

[0061] In addition, according to the above embodiment, the cross-sectional area of ​​the corner portion on the back side of the outer peripheral surface of the cover 13 is reduced due to the cutout, so that the cover 13 can be inserted and installed in the storage portion 15 of the watch case 11 during assembly and can guide the assembly work, thereby improving the assemblability.

[0062] Furthermore, the first circumferential surface 113a and the second circumferential surface 113b are connected by the top 113c that expands in a conical shape, thereby guiding the insertion into the storage portion 15, and further improving the assembly performance. Assuming that the lower surface (the other surface) of the cover 13 is simply set to a C chamfer like the upper surface (one surface), it becomes larger toward the inside, so that the C chamfer (adhesive) becomes conspicuous. In the first embodiment, the capacity of the adhesive reservoir increases in the height direction of the cutout, so it is not conspicuous when viewed from above.

[0063] The above-described embodiments are exemplary and do not limit the scope of the invention. In addition, features of a plurality of embodiments may be combined.

[0064] (Second Embodiment)

[0065] In the first embodiment, an example is shown in which the retaining groove 21h for disposing the adhesive P is formed at the corner portion on the back side of the cover 13, but the invention is not limited thereto. Figure 3 Like the cover 13A of the timepiece 1A shown in the figure, a relief groove portion 213f is formed over the entire circumference near the center in the axial direction of the outer peripheral surface 13c.

[0066] When resin glass is used as the cover 13, in the cutting process, the groove can be formed without increasing the number of steps by making the shape of the cutting tool consistent with the shape of the product side surface. In addition, when inorganic glass is used as the cover 13, the groove can be formed at the same time when the side surface is ground, so the number of working hours is not increased. An annular convex portion can be provided on a part of the grinding tool.

[0067] (Other Embodiments 1)

[0068] In the first embodiment, the top 113c of the escape groove 13f is formed into a trapezoidal shape with a tapered inclined surface, but the present invention is not limited thereto. Figure 4Like the cover 13B of the timepiece 1B shown in the figure, the evacuation groove portion 313f having a rectangular cross-sectional shape is provided.

[0069] (Other Implementation 2)

[0070] In addition, as another embodiment 2, it is also possible to Figure 5 As in the case 13C of the timepiece 1C shown in the figure, the inner surface of the groove having the escape groove portion 413f is formed in a curved shape.

[0071] (Other Implementation 3)

[0072] In the first embodiment, the second embodiment, and other embodiments 1 and 2, examples are shown in which the bottom portion of the watch case 11 facing the back side of the cover 13 is provided with the retaining groove 21h for disposing the adhesive P, but the present invention is not limited thereto. Figure 6 As shown in the cover 13D of the watch 1D, a first recessed portion, namely, a retaining groove portion 513g, is formed on the back side 13b of the cover 13D, which is the opposite surface to the bottom surface of the watch case 11. The retaining groove portion 513g is a recessed portion where the back side 13b of the cover 13D retreats toward the front side, and is configured to retain the adhesive P. In addition, in the watch 1D, no groove is formed on the bottom support portion 21f of the watch case 11, but it is configured to be flat. In this embodiment, since the remaining portion of the adhesive P supplied to the retaining groove portion 513g is also absorbed by the retreat groove portion 13f, it is possible to suppress the adhesive P from overflowing from between the watch case 11 and the cover 13D.

[0073] In addition, different embodiments may be combined. For example, the escape grooves may be formed at a plurality of locations.

[0074] The timepiece 1 is square, but may also be circular. In addition, when the timepiece 1 is circular, the inside-outside direction is the radial direction. That is, the inner peripheral side is the radial inner side, and the outer peripheral side is the radial outer side.

[0075] Several embodiments of the present invention have been described. However, the present invention is intended to be included in the inventions described in the claims and their equivalents.
