[0009] A timepiece 1 according to a first embodiment of the present invention will be described below with reference to Figs. 1 and 2. Fig. 1 is a plan view of the timepiece 1 according to the first embodiment. Fig. 2 is a cross-sectional view showing a part of the timepiece 1. In this embodiment, an example is shown in which the device is applied to the dial of the timepiece 1. In the figure, X, Y, and Z respectively indicate three mutually orthogonal directions. For example, in this embodiment, the timepiece 1 will be described as being in a position in which the first direction along the Z axis is the front-to-back direction of the timepiece 1, the X axis is the vertical direction connecting 6 o'clock and 12 o'clock on the timepiece 1, and the Y axis is the horizontal direction connecting 3 o'clock and 9 o'clock on the timepiece 1, but this is not limiting.

[0010] 1 and 2 is, for example, a wristwatch, and includes a watch case 11 forming an outer shell, a watch module 12 provided within the watch case 11, a transparent cover 13 covering the front side, which is one side in a first direction, of the watch module 12, and a back cover (not shown) covering the back side, which is the other side in the first direction, of the watch module 12. The watch 1 also includes a watch band 14 connected to two points on the outer periphery of the watch case 11, and multiple switches arranged on the outer periphery of the watch case 11.

[0011] Watch case 11 has a frame 20 that is disposed on the outer periphery of watch module 12. Watch case 11 has band attachment parts, to which watch bands 14 are attached, at two opposing locations on the outer periphery, for example at the 6 o'clock and 12 o'clock positions of the watch.

[0012] The frame 20 is made of metal or resin material, has a peripheral wall 21 that covers the outer periphery of the watch module 12 and the cover 13, and has a storage section 15 in the center that is a space in which the watch module 12 and the cover 13 are arranged. In this embodiment, the frame 20 and the storage section 15 are formed in a rectangular shape. That is, the frame 20 is configured in a quadrangle shape surrounded by two sides extending horizontally along the X axis and two sides extending vertically along the Y axis. For example, in this embodiment, the inward and outward directions of the watch case 11 are directions perpendicular to the circumferential direction and the front and back directions, and for example, the horizontal direction is the inward and outward direction on the side along the vertical direction, and the vertical direction is the inward and outward direction on the side along the horizontal direction. Note that when the watch case 11 is circular, the frame 20 and the storage section 15 are also formed in a circular shape.

[0013] The peripheral wall portion 21 has a protruding wall portion 22 that protrudes inwardly around the entire periphery. The frame body 20 may be formed by combining a plurality of case members.

[0014] The housing 15 is a recess in which the watch module 12 and cover 13 are disposed. The housing 15 is a space that is open on the front and back sides. For example, in the frame 20, the front side of the opening that constitutes the housing 15 is covered by the cover 13, and the back side is covered by a back cover.

[0015] As an example, the housing section 15 of the watch case 11 has a first housing section 15a in which the cover 13 is disposed, and a second housing section 15b in which the watch module 12 is disposed on the back side of the first housing section 15a. A protruding wall section 22, which is a part of the inner peripheral surface of the frame body 20 that protrudes inward, is disposed between the first housing section 15a and the second housing section 15b.

[0016] A plurality of steps corresponding to the arrangement of the components are formed on the inner peripheral surface of the frame body 20. For example, the surface of the frame body 20 has a first inner peripheral surface 21a facing the outer periphery of the watch module 12, a back edge surface 21b that is the back surface of the protruding wall portion 22 and is disposed on the front side of the outer peripheral edge of the watch module 12, a front edge surface 21c that is the surface of the protruding wall portion 22 and faces the back side of the periphery of the cover 13, a second inner peripheral surface 21d that faces the outer peripheral surface of the cover 13, an outer surface 21e, and a back surface.

[0017] That is, within the watch case 11, a watch module support portion is formed by a first inner surface 21a that forms the second accommodating portion 15b and a back edge surface 21b that is the back surface of the protruding wall portion 22, and a cover support portion is formed by a front edge surface 21c that is the front surface of the protruding wall portion 22 and a second inner surface 21d that constitutes the first accommodating portion 15a.

[0018] The first inner circumferential surface 21a is an inner wall surface that stands along the first direction, and is disposed opposite the outside of the outer periphery of the timepiece module 12.

[0019] The back edge surface 21b is the back surface of the protruding wall portion that continues from the front end portion of the first inner circumferential surface 21a and extends radially inward, forming a plane perpendicular to the first direction, which is the thickness direction of the watch 1. The back edge surface 21b is disposed opposite the peripheral surface of the watch module 12. For example, the back edge surface 21b of the protruding wall portion 22 serves as a retaining portion that regulates the position of the watch module 12 in the first direction. The back edge surface 21b of the protruding wall portion 22 may have steps or unevenness according to the opposing member.

[0020] The front edge surface 21c is disposed opposite to the peripheral edge of the back surface of the cover 13. The outer peripheral edge of the front edge surface 21c is disposed outside the outer peripheral edge of the back edge surface 21b.

[0021] The front edge surface 21c has a bottom support portion 21f that supports the back side of the peripheral portion of the cover 13, an evacuation recess 21g that retreats to the back side inside the bottom support portion 21f, and a retaining groove portion 21h (first recess) that retreats to the back side outside the bottom support portion 21f and in which adhesive is placed.

[0022] The bottom support portion 21f has a bottom surface portion that faces the back surface of the cover 13 in an area on the outer periphery side of the front surface of the protruding wall portion 22. The bottom support portion 21f has an upper surface (one surface) that is located on the front side of the bottom surface of the retreat recess 21g and has a flat surface portion perpendicular 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 flat surface that extends to the inner periphery side from a base end portion on the back side of the second inner periphery surface 21d and is divided into two parts by the holding groove portion 21h. That is, by forming the holding groove portion 21h in the bottom support portion 21f, the inner and outer regions of the holding groove portion 21h are each positioned on the front side of the bottom surface of the holding groove portion 21h and facing the back surface side of the outer periphery of the cover 13.

[0023] The retreat recess 21g is formed in a region on the surface of the protruding wall 22 toward the center of the watch case 11, and forms a bottom surface that retreats to the rear side of the bottom support portion 21f. The bottom surface of the retreat recess 21g is disposed with a predetermined gap G1 from the rear surface of the cover 13. In other words, between the surface of the protruding wall 22 of the watch case 11 and the rear surface of the cover 13, the central region is disposed spaced apart in the front-to-rear direction, and a gap G1 is formed whose entire periphery is surrounded by the bottom support portion 21f.

[0024] The holding groove 21h is a circumferential groove in which the area on the outer periphery of the bottom support portion 21f is recessed toward the back side, and is formed continuously around the entire circumferential direction of the frame-shaped watch case 11. The holding groove 21h holds adhesive P, and constitutes an adhesive portion that bonds the watch case 11 and the cover 13. Here, the dimension in the first direction (along the Z axis), which is the depth direction of the holding groove 21h, is configured to be shallower than the dimension in the depth direction of the adjacently formed retraction recess 21g. Also, the holding groove 21h is configured to have a dimension in the groove width direction along the inward / outward direction larger than the depth direction along the first direction (along the Z axis).

[0025] The depth of the holding groove 21h may be greater than the depth of the retreat recess 21g. Also, the depth of the holding groove 21h may be greater than the groove width of the holding groove 21h.

[0026] The second inner peripheral surface 21d is an inner wall surface that stands on the front side along the first direction from the edge on the outer peripheral side of the surface of the protruding wall portion 22, and is disposed opposite to the outside of the outer periphery of the cover 13. For example, the second inner peripheral surface 21d is located outside the first inner peripheral surface 21a.

[0027] The outer surface 21e extends outward from the front end of the second inner circumferential surface 21d, and constitutes the surface of the front side and outer circumferential side of the watch case 11.

[0028] The back surface of the frame 20 is joined to the back cover by adhesive or fastening. For example, a waterproof ring is attached to the back surface of the frame 20 to make the gap between the frame 20 and the back cover airtight.

[0029] Clock module 12 is housed in housing section 15 of frame 20. For example, clock module 12 is placed on the back side of cover 13, and placed in first housing section 15a, which is the back area of ​​housing section 15. For example, clock module 12 includes a display device that displays various information such as the time, and a circuit board on which various electronic components such as an IC and an antenna are mounted as a drive unit. Clock module 12 also includes a battery, a solar board, various sensor components, and various other components necessary for the clock function. In this embodiment, the display device and circuit board that are stacked are configured, for example, in a rectangular shape that corresponds to the shape of watch case 11.

[0030] The cover 13 is a transparent member formed of a light-transmitting material such as SiO2 glass. For example, the cover 13 is a rectangular plate-shaped watch glass that conforms to the shape of the first housing portion 15, and is disposed on the front side of the watch module 12 to cover the front side of the watch module 12. For example, the cover 13 is supported on the inner peripheral edge of the opening on the front side of the watch case 11. The rear peripheral surface of the cover 13 is disposed opposite the bottom support portion 21f having the holding groove portion 21h, and is bonded to the watch case 11 by the adhesive P supplied to the holding groove portion 21h. As an example, in this embodiment, the cover 13 is joined to the frame body 20 of the watch case 11 by the adhesive P, with a packing interposed between the cover 13 and the frame body 20 of the watch case 11.

[0031] The cover 13 is formed in a plate shape 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. The edge between the front surface 13a and the outer peripheral surface 13c is chamfered to form an inclined surface 13d.

[0032] An escape groove 13f (second recess) is formed as a notch formed all around the circumference in the circumferential direction at the edge between the back surface 13b and the outer peripheral surface 13c of the cover 13, i.e., at a corner portion which is the end portion on the back side of the outer peripheral surface 13c. That is, a part of the back side area of ​​the outer peripheral surface 13c of the cover 13 is retreated to the inside of the watch case 11 more than the front side area.

[0033] For example, the outer peripheral surface 13c of the cover 13 has a first peripheral surface portion 113a on the front side, a second peripheral surface portion 113b retreated inward from the first peripheral surface portion 113a, and a ceiling portion 113c connecting the first peripheral surface portion 113a and the second peripheral surface portion 113b, which are continuous with each other. That is, the relief groove portion 13f is formed by the second peripheral surface portion 113b, which is a vertical surface portion facing the inner surface of the peripheral wall portion of the storage portion 15 with a gap therebetween, and the ceiling portion 113c, which faces the bottom surface portion of the case 11 at an angle.

[0034] The first peripheral surface portion 113a is disposed along and facing the second inner peripheral surface 21d of the frame 20.

[0035] The second circumferential surface portion 113b (vertical surface portion) faces the second inner circumferential surface 21d with a predetermined gap G2 therebetween. That is, the second circumferential surface portion 113b is disposed at a position retreated inward from the first circumferential surface portion 113a.

[0036] The ceiling portion 113c connects the first peripheral surface portion 113a and the second peripheral surface portion 113b. The ceiling portion is inclined in the front-back direction and the inward-outward direction. For example, the ceiling portion has a tapered inclined surface extending outward and toward the front side from the second peripheral surface portion 113b.

[0037] For example, the cover 13 is configured such that the area of ​​a cross section taken along the second circumferential surface portion 113b and perpendicular to the first direction is smaller than the area of ​​a cross section taken along the first circumferential surface portion 113a and perpendicular to the first direction.

[0038] The first peripheral surface portion 113a and the second peripheral surface portion 113b have surfaces parallel to each other. For example, each of the peripheral surface portions 113a and 113b has two sets of vertical and horizontal flat portions.

[0039] In a cross-sectional view, the relief groove portion 13f is configured to have a trapezoidal shape with an inclined side on the front side. The relief groove portion 13f is disposed apart from the holding groove portion 21h, where the adhesive is disposed, with a part of the bottom support portion 21f sandwiched between them. That is, the relief groove portion 13f is disposed apart from the holding groove portion 21h on the outer periphery side of the watch case 11. The relief groove portion 13f is configured so that the dimension Lz in the first direction along the front-back direction is larger than the dimension Lx in the inner-outer direction perpendicular 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 groove depth direction along the inner-outer direction. The relief groove portion 13f becomes an escape portion (adhesive escape structure portion) into which the excess of the adhesive P disposed in the holding groove portion 21h enters.

[0040] At least one of the holding groove 21h, which is the first recess, and the relief groove 13f, which is the second recess, holds the adhesive. At least one of the holding groove 21h and the relief groove 13f constitutes an adhesive relief structure that accommodates any adhesive that overflows. In other words, the timepiece 1 as a device has an adhesive relief structure.

[0041] For example, when an excess of adhesive P provided in the holding groove 21h enters the relief groove 13f, the relief groove 13f becomes an adhesive escape structure. Alternatively, when an excess of adhesive P provided in the relief groove 13f enters the holding groove 21h, the holding groove 21h becomes an adhesive escape structure.

[0042] For example, when cover 13 is formed by molding resin glass, escape groove 13f can be formed without increasing the number of steps by forming a protrusion on the mold when pouring resin into a metal mold for molding. Also, when cover 13 is made of inorganic glass, escape groove 13f can be formed at the same time when polishing the side surface by providing a protrusion or step on a polishing tool.

[0043] The watch band 14 is connected to the outer periphery of the watch case 11 at two opposing points and includes a pair of band members and a connecting mechanism such as a buckle.

[0044] The switch is provided, for example, on the outer periphery of the case, and when pressed by an operator, switches the mode of the clock module 12, adjusts the time, and so on.

[0045] The watch case 11 and cover 13 constructed as above are adhesively fixed to the cover 13 by adhesive P placed in the retaining groove portion 21h.

[0046] For example, in the assembly process of the watch 1, adhesive P is applied to the retaining groove portion 21h formed on the outer periphery of the bottom surface of the storage portion 15 of the watch case 11, and the cover 13 is inserted from the front side of the frame body 20 of the watch case 11 and glued in place.

[0047] The adhesive P is, for example, a silicone or urethane resin that has elasticity and hardens depending on temperature and humidity.

[0048] That is, the manufacturing method of watch 1 according to this embodiment includes a first step of applying adhesive to holding groove 21h as a first recess formed in at least either the bottom surface inside storage compartment 15 of case 11 or the underside of cover 13, and a second step of inserting cover 13 into storage compartment 15 of case 11 and adhesively fixing it in place. In the second step, the adhesive that has overflowed from inside holding groove 21h flows into escape groove 13f as a second recess formed in the outer circumferential surface of cover 13.

[0049] With the device and watch 1 of this embodiment, even if the adhesive P supplied to the holding groove portion 21h during the assembly process of the watch 1 overflows onto the outer side surface, the adhesive P will enter the escape groove portion 13f formed on the outer surface of the cover 13, thereby preventing the adhesive P from overflowing onto the outer surface of the case.

[0050] In addition, the relief groove portion 13f has a structure having a peripheral surface that stands toward the front side, and compared to a chamfered shape, for example, the dimension in the front-back direction can be made longer, thereby making the dimension in the inside-outside direction smaller. That is, the volume of the relief groove can be secured without impairing the appearance. For example, when forming a C-chamfer at the corner of the back side of the cover 13, it is necessary to make it larger on the inside in order to secure the volume, which affects the appearance, but in the above embodiment, by securing the dimension in the first direction along the front-back direction, the shape becomes inconspicuous when viewed from the front side.

[0051] Conventionally, when a groove is formed on the inner peripheral surface of the case, it is necessary to add a cutting process using a cutting tool. However, when resin glass is used for the cover 13, for example, the resin is poured into a mold and molding is performed, so by forming a protrusion on the mold, it can be formed without increasing the number of steps. Also, when inorganic glass is used for the cover 13, the notch shape can be formed during the side polishing that is usually performed, so the first recess can be formed at the same time. Therefore, the escape portion for the adhesive can be easily formed without increasing the number of steps.

[0052] In addition, the relief groove 13f is not continuous with the holding groove 21h, and is separated from the holding groove 21h with a part of the bottom support portion 21f sandwiched therebetween, so that the volume of the holding groove 21h can be reduced and the required amount of adhesive can be reduced, and excess adhesive can be absorbed while maintaining adhesion. In other words, the adhesive is distributed preferentially to the holding groove 21h, and then the excess adhesive P can be absorbed by the relief groove 13f.

[0053] In addition, in the cover 13 in the above embodiment, the cross-sectional area of ​​the corner portion on the back side of the outer peripheral surface is reduced due to the notch, which acts as a guide during assembly when inserting and attaching the cover 13 into the storage portion 15 of the watch case 11, thereby improving the ease of assembly.

[0054] Furthermore, first peripheral surface portion 113a and second peripheral surface portion 113b are connected by ceiling portion 113c which expands in a tapered shape, thereby guiding insertion into storage portion 15 and further improving ease of assembly. If the bottom surface (the other surface) of cover 13 were simply C-chamfered like the top surface (one surface), the C-chamfer (adhesive) would become noticeable as it would become larger on the inside. In the first embodiment, the capacity of the adhesive reservoir is increased in the height direction of the cutout, so it is not noticeable when viewed from above.

[0055] The above-described embodiments are merely examples and do not limit the scope of the invention. Furthermore, features of multiple embodiments may be combined.

[0056] Second embodiment In the first embodiment described above, an example was shown in which a retaining groove 21h in which adhesive P is placed is formed in a corner portion on the back side of the cover 13, but this is not limited to this. For example, as in the case of cover 13A of a watch 1A shown in Fig. 3 as a second embodiment, an escape groove 213f may be formed around the entire circumference near the center in the axial direction of the outer circumferential surface 13c.

[0057] When resin glass is used for the cover 13, the grooves can be formed without increasing the number of steps by matching the cutting tool shape to the product side shape in the cutting process. Also, when inorganic glass is used for the cover 13, the grooves can be formed at the same time as the side polishing, so there is no increase in the number of steps. This is possible by providing a ring-shaped protrusion on part of the grindstone.

[0058] (Another embodiment 1) In the first embodiment, the ceiling 113c of the relief groove 13f is formed in a trapezoid shape with a tapered inclined surface, but this is not limited to this. As another embodiment 1, the cover 13B of the watch 1B shown in Fig. 4 may have a relief groove 313f with a rectangular cross section.

[0059] (Another embodiment 2) As another example, a cover 13C of a watch 1C shown in FIG. 5 as a second alternative embodiment may have an escape groove portion 413f in which the inner surface of the groove is formed into a curved shape.

[0060] (Other embodiment 3) In the first embodiment, the second embodiment, and other embodiments 1 and 2, an example was shown in which the holding groove 21h in which the adhesive P is placed is formed on the bottom surface of the watch case 11 facing the back side of the cover 13, but this is not limited to this. As shown in FIG. 6 as another embodiment 3, a holding groove 513g may be formed as a first recess on the back surface 13b side of the cover 13D, which is the opposing surface facing the bottom surface of the watch case 11. The holding groove 513g is a recess in which the back surface 13b of the cover 13D is retracted to the front side, and is configured to be able to hold the adhesive P. Note that in the watch 1D, no groove is formed in the bottom support portion 21f of the watch case 11, and it is configured to be flat. In this embodiment as well, the excess of the adhesive P supplied to the holding groove 513g is absorbed by the escape groove 13f, so that the adhesive P can be prevented from spilling out from between the watch case 11 and the cover 13D.

[0061] Also, different embodiments may be combined, and for example, the relief grooves may be formed in a plurality of locations.

[0062] Although the watch 1 is rectangular, it may be circular. If the watch 1 is circular, the inward and outward directions are radial directions. In other words, the inner circumference side is the radially inward side, and the outer circumference side is the radially outward side.

[0063] Although several embodiments of the present invention have been described, the present invention is encompassed within the scope of the invention described in the claims and their equivalents. [Explanation of symbols]
