Description

Technical Field

[0001] This invention relates to a watch and a watch case.

Background Art

[0002] In watches, particularly portable ones that require waterproof and dustproof properties, a driving unit, a time display unit, etc. are housed inside a housing (case), and a transparent windshield glass located on the upper surface or the front is joined to the case so that the display content by this display unit can be visually recognized from the outside. It is known that an adhesive is used for the joining.

[0003] The adhesive used for the joining is usually used at a position not visible from the outside. However, since the adhesive has fluidity before adhesion and spreads somewhat from the joining surface when pressure-bonded and fixed, if this spreading becomes large and protrudes to a position visible to the user, the appearance deteriorates. In contrast, Patent Document 1 discloses a technique for suppressing unnecessary outflow to the outside of the joining surface by providing a space where the adhesive stays on the joining surface between the windshield glass of the case and the case.

Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the upper surface of the clock 1 of the present embodiment. The clock 1 is, although not particularly limited, for example, a wristwatch that displays time by the hands 2. The clock 1 includes a housing 5 (clock case), a windproof glass 6 (see FIG. 2) not shown in the figure, hands 2 that rotate below the windproof glass 6 to display time and the like, a dial 3 located below the hands 2 and having scales and the like not shown in the figure, and a partition plate 8 that is located substantially annularly along the inner peripheral surface 5a of the housing 5 around the hands 2 on the dial 3. The windproof glass 6 is a member that transmits light (light-transmissive member), and the dial 3, the hands 2, and the partition plate 8 are visible from the outside through the windproof glass 6.

[0011] The housing 5 houses various components (functional components) such as a control unit of the clock 1, the above-described hands 2, the dial 3, and the partition plate 8, and a battery inside. The housing 5 has a cylindrical shape with open top and bottom, and here, a substantially cylindrical shape. The material of the housing 5 is not particularly limited, but is a material to which the adhesive 7 described later adheres appropriately. Here, for example, it is various resins. The windproof glass 6 is positioned so as to cover one end (first end) on the open upper surface side of this housing. Among the various components located inside the housing 5, the hands 2 are included. The side opposite to the first end of the housing 5 (one end on the lower surface side) may also be open, and this one end may be sealed with a back cover not shown in the figure.

[0012] FIG. 2 is a diagram showing a part of the cross-section of the clock 1. The housing 5 has a groove 51a on the upper surface of the protruding portion 51. The windshield glass 6 is supported and fixed by the upper surface of the protruding portion 51.

[0013] The windshield glass 6 has an annular thin film 61 (thin film layer) along the periphery of the lower surface. This thin film 61 is a colored (for example, silver) light non-transmissive film, and is formed by printing on the windshield glass 6, for example. This thin film 61 is a light-shielding film, and the adhesive 7 and the structure of the housing 5 located further below the thin film 61 are shielded by the thin film 61 and not visible from the upper surface side.

[0014] The adhesive 7 joins the thin film 61 (that is, the periphery of the lower surface) of the windshield glass 6 to the upper surface of the protruding portion, and joins the side surface to the inner peripheral surface 5a above the protruding portion 51. The adhesive 7 is applied to the groove 51a, and the adhesive 7 on the protruding portion 51 mainly stays in the groove 51a. Also, there is a gap between the side surface of the windshield glass 6 and the inner peripheral surface 5a, and the adhesive 7 also enters and stays in this gap. That is, due to the existence of these grooves 51a and the gap, the adhesive 7 does not protrude greatly from the joint surface when it is crimped and heated. The adhesive 7 does not necessarily have to fill the entire gap as long as it is distributed to obtain the required joint strength and the required waterproofness, dustproofness, etc. The adhesive 7 is not particularly limited, but may be, for example, a thermosetting one. Some of these thermosetting adhesives expand slightly (such as a few percent) during heat curing. The color of the adhesive 7 does not have to be colorless and transparent, and may be colored (here, white is also included in the colored). In this way, the side surface of the windshield glass 6 is joined to the inner peripheral surface 5a of the housing 5 via the adhesive 7, and the periphery of the lower surface is joined to the upper surface of the protruding portion 51 via the adhesive 7.

[0015] Also, the lower end of the side surface of the windshield glass 6 is chamfered so that the adhesive 7 can easily spread across the lower surface side and the side surface side of the windshield glass 6 during joining. This chamfering may be made at an angle deeper than 45 degrees (an angle at which the chamfered surface 6a rises more steeply with respect to the bottom surface).

[0016] On the tip side surface (inner surface) of the protrusion 51, the outer peripheral surface 8a of the baffle plate 8 faces (the facing portion). There is a gap in this facing portion along the windshield glass 6. The inner edge of the thin film 61 of the windshield glass 6 extends inside beyond the outer edge of the baffle plate 8. There may be a minute gap between the upper surface of the baffle plate 8 and the windshield glass 6.

[0017] Figure 3 is a diagram for explaining the notch position. As shown in Fig. 3(a), the housing 5 has a plurality of protrusions 52 (here, four at 90-degree intervals) protruding from the inner peripheral surface 5a along the inner peripheral surface 5a. The circle passing through the tip positions of the protrusions 52 is substantially the same size as (actually, slightly larger than) the outer edge of the windshield glass 6, whereby the position of the windshield glass 6 with respect to the housing 5 (inner peripheral surface 5a) is defined. That is, the protrusions 52 may be positioned at three or more locations at an angular difference of less than 180 degrees each so as to be able to define this circle.

[0018] As described above, the distance from the center position in plan view of the housing 5 to the inner peripheral surface 5a is partially very narrow in the cross section including this protrusion 52. Therefore, when the windshield glass 6 is joined to the housing 5, the adhesive 7 is extruded from this narrow portion and spreads to the surroundings in response to the expansion due to heating as described above. In particular, on the bottom surface side of the windshield glass 6, inside the groove 51a, since the gaps between the windshield glass 6, the protrusion 51, and the baffle plate 8 are minute, the width by which the extruded adhesive 7 spreads inward is likely to be large with respect to the volume of the adhesive 7. When the adhesive 7 spreads inside beyond the thin film 61, the adhesive 7 will be visible from the outside, deteriorating the appearance.

[0019] The baffle plate 8 shown in Fig. 3(b) has a C-shaped configuration with a cut 81 in one direction, but may be a continuous annular shape. Although not particularly limited, here, the baffle plate 8 is made of resin.

[0020] The parting plate 8 has cutouts 82 to 86 (notches). The cutouts 82 and 83 are located on both sides of the cut 81. The cutouts 84 to 86 are each located at 90-degree intervals including the cutout 83. The angular range of these cutouts 83 to 86 includes the position (angular direction) of the protrusion 52 in plan view. The widths of the cutouts 83 to 86 in the angular direction (the direction along the inner peripheral surface 5a) are all wider than the width of the protrusion 52 in the angular direction. Also, the volume (capacity) cut out from the cylindrical parting plate 8 by the cutouts 83 to 86 is larger than the volume of each protrusion 52.

[0021] These cutouts do not necessarily have to be intentionally added according to the protrusion 52, and those used / used for other purposes may be diverted. For example, the parting plate 8 is usually obtained by injection molding in which resin is poured into a mold and solidified. The surface including the cutting trace of the gate, which is the resin inflow path at this time, may be made into the cutouts 84, 86, etc. Also, when the parting plate 8 has the cut 81, at the time of injection molding, both sides of the cut 81 may be connected by a connection path (bridge), so it has the cutting trace of this bridge, and the surface adjacent to the cut 81 (the position corresponding to the cut 81. Here, the correspondence indicates the distance from the cut 81 determined according to the manufacturing method of the parting plate 8, etc.) may be made into the cutouts 82, 83. The shape of the gate and the bridge may be appropriately determined as necessary. Also, the positions of the cutouts 82, 83 related to the bridge do not necessarily have to be in contact with and adjacent to both sides of the cut 81. They may be separated from the cut 81.

[0022] FIG. 4 is a diagram for explaining the case when the parting plate 8 is viewed from the side from the side of the cut 81. In the cutouts 82, 83 located adjacent to both sides of the cut 81 and where the bridge has been cut, these cutting traces 87 may remain. The cutting traces 87 are not limited to those protruding from the cutout surfaces of the cutouts 82, 83 or having a rough surface. Also, the cross-sectional shape, size, etc. of the bridge may be arbitrary.

[0023] The positional relationship between the gate and the bridge is determined by the direction of the required cut 81 and the like. Therefore, when the notch does not match the protrusion 52 in position or the number is insufficient, separate notches 85 or the like may be formed.

[0024] FIG. 5 shows a cross-sectional view taken along the cutting line AA in FIG. 3(a) and a cross-sectional view taken along the cutting line BB, respectively.

[0025] The cross-sectional view taken along the cutting line AA shown in FIG. 5(a) includes the protrusion 52 and the notch 84 having a separation mark at the position of the gate as described above. The portion (notch surface) of the outer peripheral surface 8a facing the inner peripheral surface 5a of the parting plate 8 corresponding to the notch 84 may be a flat surface (a straight line in plan view). Accordingly, in the cross-section including the notch 84, a gap corresponding to the height of the outer periphery of the parting plate 8 is formed between the inner side surface of the protruding portion 51 and the outer peripheral surface 8a of the parting plate 8. The cross-section including the notch 86 may have the same structure as this. Also, the cross-section including the notch 82 corresponding to the trace of the bridge may have the same structure as this. That is, there is no need to distinguish between the trace of the gate and the trace of the bridge. Since the angle difference between the notch 83 and the notch 82 is small, the parting plate 8 does not have the protrusion 52 in the direction corresponding to this notch 83, but may have the protrusion 52 in the direction corresponding to the notch 83.

[0026] The cross-sectional view taken along the cutting line BB shown in FIG. 5(b) has the protrusion 52 and the notch 85 having no cutting trace of the gate as described above. This notch 85 has a cross-sectional shape different from that of the notch 84 here, although it is not particularly limited. Here, instead of completely cutting out the parting plate 8 in the vertical direction, only a part near the upper surface is cut out. Even with such a shape, it is sufficient if the notch has a volume capable of receiving the adhesive 7 extending in the central direction along the lower surface of the windshield glass 6.

[0027] In this way, due to the cutout portions 82 to 86, the gap in a partial region along the lower surface of the windshield glass 6 in the plane view range (angular direction) including the protrusion 52, which is a portion of the opposing part between the inner surface of the protruding portion 51 and the cut-off plate 8, is wider than the gap in the portion other than the partial region. By providing such a wide-gap portion in an angular range where the gap between the inner peripheral surface 5a and the windshield glass 6 is narrow due to the protrusion 52, the adhesive 7 extruded from the narrow gap and spreading particularly in the central direction of the windshield glass 6 stays in this gap, suppressing further spreading in the central direction. Thereby, it is possible to suppress the adhesive 7 from spreading inside the thin film 61 and becoming visible from the outside.

[0028] [Modification Example] FIG. 6 is a cross-sectional view showing a modification example of the clock 1 of the present embodiment. This cross-section includes the same protrusion 52 as the cross-section shown in FIG. 5(b), and the same reference numerals are given to the same parts and the description thereof is omitted.

[0029] In this modification example, the cut-off plate 8 does not have a cutout portion in the same cross-section as the protrusion 52. Instead, the protruding portion 51 of the housing 5 has a cutout portion 511 whose protruding width is partially narrower than the other parts (other portions). As long as the gap between the cut-off plate 8 and the protruding portion 51 along the windshield glass 6 is partially widened, the cutout portion serving as the gap may be in either the cut-off plate 8 or the protruding portion 51.

[0030] Here, the cutout portion 511 is located only in a portion further inside than the inner edge 51b of the groove 51a, but the edge 51b may be thinner or may be locally absent.

[0031] As described above, the clock 1 of the present embodiment includes a housing 5 with one end (first end) on the upper surface side open, a windshield glass 6 which is a member located at the first end and transmits light, a partition plate 8 which is a functional component located inside the housing 5, and an adhesive 7 joining the housing 5 and the windshield glass 6. The housing 5 has a protruding portion 51 protruding inward from its inner peripheral surface 5a and extending in the circumferential direction, and a plurality of protruding portions 52 protruding inward from the inner peripheral surface 5a and defining the position of the windshield glass 6 with respect to the inner peripheral surface 5a. The side surface of the windshield glass 6 is joined to the inner peripheral surface 5a via the adhesive 7, and the peripheral edge of its lower surface is joined to the upper surface of the protruding portion 51 via the adhesive 7. The outer peripheral surface 8a of the partition plate 8 extends along the inner side surface of the protruding portion 51. There is a gap in the opposing portion of the protruding portion 51 and the partition plate 8 along the windshield glass 6, and the gap in the region formed by the notches 83 to 86, which is a part including the position of the protruding portion 52, is wider than the gap in the portion other than the region formed by the notches 83 to 86. By forming the gap in accordance with the protruding portion 52 in this way, in the clock 1, while surely aligning the position of the windshield glass 6, it is possible to suppress the adhesive 7 from protruding to unnecessary places and suppress the deterioration of the appearance.

[0032] Also, a part of the gap related to the notches 83 to 86 is due to the partition plate 8. Since the spread of the adhesive 7 to the inside of the thin film 61 depends on the position and shape of the partition plate 8 (functional component), by adjusting the gap on the side of the partition plate 8, the number of patterns of the shape according to the product of the housing 5 can be reduced.

[0033] Also, the width in the direction along the inner peripheral surface 5a of the notches 82 to 86 is wider than the width in the direction along the inner peripheral surface 5a of the protruding portion 52. Thereby, when joining, the adhesive 7 can be more easily induced to spread in the circumferential direction, and the thickness of the notches 82 to 86 can be kept small, minimizing the influence on the size of the display screen of the clock 1 and the like.

[0034] Further, the volume of each of the cut-out portions of the cut-out portions 83 to 86 is larger than the volume of the corresponding protrusion 52. As a result, even if all of the adhesive 7 extruded by the amount of the protrusion 52 flows into the cut-out portions 83 to 86, it does not overflow, so that the spread of the adhesive 7 to the inside of the thin film 61 can be more reliably suppressed.

[0035] Further, the surfaces of the cut-out portions 83 to 86 of the parting plate 8 are made of resin, and at least a part of the surfaces of the cut-out portions 83 to 86 has a cutting trace 87. That is, not all of the cut-out portions 83 to 86 need to be formed to store the adhesive 7. The portions after these gates and bridges of the cut-outs generated in applications such as gates and bridges are separated may be diverted and used as a place where the adhesive 7 efficiently accumulates.

[0036] Further, the parting plate 8 has a cut 81 in the direction along the tip side surface (inner surface) thereof, and may have, for example, adjacent cut-out portions 82 and 83 at positions corresponding to the cut 81. That is, depending on the function of the parting plate 8 and the balance with the positions of other parts, the parting plate 8 does not necessarily have to be annular. Also, the position of the cut 81 itself may correspond to the position of the protrusion 52, but when other parts are located at the position of the cut 81, it is possible to utilize the positions of the adjacent cut-out portions 82 and 83, mainly the position where the bridge is cut off.

[0037] Further, the windshield glass 6 has an annular thin film 61 on the joint surface with the upper surface of the protruding portion 51, and the adhesive 7 joins the thin film 61 and the upper surface of the protruding portion 51. In this way, by joining the thin film 61 with the adhesive 7, the adhesive 7 is not directly attached to the lower surface of the windshield glass 6, so that the adhesive 7 does not interfere with the display surface by the pointer 2 or the like through the windshield glass 6. And since the adhesive 7 can be hidden by the thin film 61, the appearance can be improved.

[0038] In particular, when the adhesive 7 is colored and easily visible from the upper surface side, by preventing the adhesive 7 from spreading to the inside of the thin film 61, a decrease in appearance can be appropriately suppressed.

[0039] Further, the protrusion 52 is located between the protruding portion 51 and the first end. Thereby, the windshield glass 6 can be stably supported, and the adhesive 7 extruded from the region between the inner peripheral surface 5a and the windshield glass 6 can be appropriately made to flow into and stay in the gap between the protruding portion 51 and the outer peripheral surface 8a.

[0040] Also, the watch case of the present embodiment includes a housing 5 with the first end (the upper surface side end portion) open. The housing 5 has a protruding portion 51 that protrudes inward from the inner peripheral surface 5a of the housing 5 and extends in the circumferential direction, and on which a windshield glass 6 covering the first end is disposed on the upper surface, and a plurality of protrusions 52 that protrude inward from the inner peripheral surface 5a and define the position of the windshield glass 6 with respect to the inner peripheral surface 5a. At least a part (notch portion 511) including the position of the protrusion 52 among the opposing portions of the protruding portion 51 along the windshield glass 6 is narrower than the other portions of the part. In this way, there may be a notch portion 511 on the side of the housing 5, and thereby, when the windshield glass 6 is joined by the adhesive 7, the spread of the adhesive 7 inward along the lower surface of the windshield glass 6 can be suppressed. Thereby, it is possible to suppress the adhesive 7 from becoming visible from the upper surface side through the windshield glass 6 and to suppress a deterioration in appearance.

[0041] Note that the present invention is not limited to the above-described embodiment, and various modifications are possible. For example, in the above-described embodiment, the protrusion 52 and the notch portions 83 to 86 have been described as corresponding one-to-one, but in a case where there is a portion where the intervals of the protrusions 52 are narrow, a plurality of protrusions 52 may be included in one notch portion. In this case, it is preferable that the notch portion has a volume larger than the sum of the volumes of the plurality of protrusions 52.

[0042] In the above embodiment, the case where the notches 82 to 86, which are the traces where gates, bridges, etc. are separated from the resin-made parting plate 8, are used as gaps for ink pooling has been described. However, they may also be gaps formed by notches provided exclusively. In particular, in the case of functional components such as the parting plate 8 made of metal instead of resin, such separation traces do not occur, so they may all be provided separately and exclusively.

[0043] Also, the number and intervals of the notches 82 to 86 may be arbitrarily determined within a range where the position of the windshield glass 6 can be defined. Also, the shapes and sizes of the notches 82 to 86 may be different for each.

[0044] Also, the notch surfaces of the notches 82 to 86 do not have to be planar in plan view. They may be concave or convex curved surfaces.

[0045] Also, since not all of the adhesive 7 extruded from the protrusion 52 flows into the notches 82 to 86, the volume of each of the notches 82 to 86 does not necessarily have to be larger than the volume of the protrusion 52. Conversely, if the required volume is obtained, notches with a width in the circumferential direction narrower than the width of the protrusion 52 may be used.

[0046] Also, the color of the adhesive 7 is not particularly limited and may be colorless and transparent. Also, the joint surface of the thin film 61 with the windshield glass 6 may be of an appropriate color according to the design of how it looks from the upper surface side, etc. Also, the adhesive 7 does not necessarily have to be thermosetting, and it does not necessarily have to expand during thermosetting.

[0047] In the above-described embodiment, the timepiece has been described as one that performs display by means of the pointer 2. However, it may be a timepiece having a digital display screen. Further, the timepiece 1 is not limited to an electronic timepiece. It may be a mechanical timepiece that uses a spring or the like. Also, the timepiece 1 does not necessarily have to be a product dedicated to time display. It may have basic functions such as a stopwatch and an alarm. Furthermore, it may have physical sensors such as a barometric pressure sensor, a geomagnetic field sensor, a temperature sensor, an acceleration sensor, and an optical parameter sensor, and be a multifunctional product (including a smartwatch) capable of measuring and displaying temperature, direction, altitude, weather changes, usage status, the activity status of the user, pulse, SpO2, etc. Also, it may be capable of acquiring various information from the outside through the communication unit and performing display and notification operations. Also, the timepiece 1 is not limited to a wristwatch worn on the wrist. It may be something worn on other parts of the body, or a pocket watch that is placed in a pocket and carried around.

[0048] Also, the opening end of the housing 5 and the outer shape of the windproof glass 6 do not have to be circular. These shapes may be elliptical, or may be a rounded or chamfered polygonal shape or the like. Also, the outer shape of the windproof glass 6 and the outer shape of the index plate 8 may be different shapes. In particular, in the case of the timepiece 1 having a digital display screen, it may be the shape of the index plate 8 corresponding to the digital display screen.

[0049] Also, in the above-described embodiment, the index plate 8 has been described as an example of a functional component, but it is not limited to this. When the dial 3 directly contacts the protruding portion 51 of the housing 5, the dial 3 may be a functional component, or may be a component used for other purposes. In addition, the specific configurations, the contents and procedures of the processing operations, etc. shown in the above-described embodiment can be appropriately changed without departing from the spirit of the present invention.
