Summary of the Invention

Problems to be Solved by the Invention

[0004] As the size and shape of the clock case change, the pulling force applied to the fusee when the clock is used may change. Therefore, it is preferable to change the size of the protrusion formed on the back presser according to the pulling force applied to the fusee. In the technique described in Patent Document 1, since the protrusion is formed on the back presser included in the movement, a plurality of types of movements having a back presser with a protrusion according to the pulling force applied to the fusee are to be prepared.

[0005] However, if a plurality of types of movements are prepared, the design / selection of the movement to be used becomes complicated, and the inventory management of the movement may become complicated, which may increase the manufacturing cost of the clock.

[0006] The present invention aims to solve these problems and provide a watch that prevents the crown from coming off together with the winding stem while maintaining the versatility of the movement. [Means for solving the problem]

[0007] The watch according to the present invention comprises a watch case having a case and a back cover that engages with the case; a movement having a winding stem to which a crown is attached and a saddle that engages with the winding stem, and disposed inside the watch case; an intermediate frame disposed between the case and the movement and holding the movement inside the watch case; and a regulating part disposed between the saddle and the back cover and restricting the movement of the saddle, wherein the intermediate frame is disposed between the back cover and the regulating part and has a pressing part that presses against the regulating part.

[0008] Furthermore, in the clock according to the present invention, it is preferable that the inner frame and the pressing part are integrally molded from resin.

[0009] Furthermore, in the clock according to the present invention, the inner frame preferably has an outer peripheral portion formed along the outer circumference of the movement, and the pressing portion is preferably located inside the outer peripheral portion.

[0010] Furthermore, in the watch according to the present invention, the inner frame preferably has a plurality of flexible protrusions that project from the outer periphery toward the back cover, and the pressing portion is preferably positioned so as not to overlap with the protrusions when the inner frame is viewed in plan.

[0011] Furthermore, in the watch according to the present invention, it is preferable that the pressing portion extends between the surface of the regulating portion on the back cover side and the surface of the back cover on the regulating portion side. [Effects of the Invention]

[Modes for carrying out the invention]

[0014] The clock according to the present invention will be described below with reference to the figures. However, it should be noted that the technical scope of the present invention is not limited to these embodiments, but extends to the invention described in the claims and its equivalents.

[0015] (Embodiment 1) Figure 1 is a front view of the clock 1 according to Embodiment 1, and Figure 2 is an exploded perspective view of the clock 1 shown in Figure 1. In Figure 2, the movement 14 is shown schematically to avoid making the drawing too complex.

[0016] The watch 1 includes a watch case 11, a crystal glass 12, a dial 13, an hour hand 133, a minute hand 134, a second hand 135, a movement 14, a crown 15, and a central frame 17, etc.

[0017] The watch case 11 is a flat, substantially disc-shaped member that houses components such as the dial 13 and the movement 14. The watch case 11 is formed by an annular body 112 and a back cover 113 that is disposed on the back surface of the watch 1 and engaged with the body 112.

[0018] The back cover 113 is assembled to the rear portion of the body 112 via a packing 115. The packing 115 is an annular elastic member formed from an elastic material such as rubber, and is also referred to as a sealing, gasket, or O-ring. Further, an insertion hole through which the winding stem 16, described later, is inserted is formed in the outer peripheral portion of the body 112. The back cover 113 is a substantially disc-shaped member, and presses the middle frame 17 when attached to the body 112, as described later.

[0019] In one example, the body 112 and the back cover 113 are formed of stainless steel. The body 112 and the back cover 113 may be formed of other metals such as titanium or gold, or resin.

[0020] The windshield glass 12 is attached to the front surface of the watch case 11 so as to be surrounded by the body 112. The windshield glass 12 is a transparent glass plate formed in a disc shape, and is formed of sapphire glass, mineral glass, or the like. The windshield glass 12 is adhered to the front portion of the body 112 by an adhesive member, and covers the dial 13, the hour hand 133, the minute hand 134, and the second hand 135, thereby protecting them while allowing them to be visible from the front.

[0021] The dial 13 is a flat member on which the hour numerals 131 indicated by the hour hand 133, the minute hand 134, and the second hand 135 are displayed on the front surface. The dial 13 is built into the watch case 11 so as to be parallel to the windshield glass​​​The hour hand 133, minute hand 134, and second hand 135 are positioned on the front of the dial 13 and are driven by a movement 14 positioned on the back of the dial 13 to point to the hour markers 131 displayed on the dial 13. The rotation axes of the hour hand 133, minute hand 134, and second hand 135 are inserted into coaxial hour hand pipes, minute hand pipes, and second hand shafts, respectively, and connected to the movement 14. The hour hand 133, minute hand 134, and second hand 135 are driven by rotational force transmitted from the movement 14 via the rotation axes. The movement 14 shown in the figure is a quartz movement positioned inside the watch case 11. However, the movement 14 is not limited to a quartz movement; for example, it may be a mechanical movement. Furthermore, the movement 14 may have functions other than time display, such as a calendar function that displays the date.

[0023] The crown 15 is a component that is operated when setting the time, etc. The crown 15 is a rotatable component, and in one example it is located at the 3 o'clock position on the dial 13 on the side of the watch 1. The rotational force of the crown 15 is transmitted to the hour hand 133 and minute hand 134 via the movement 14 for setting the time, causing the hour hand 133 and minute hand 134 to rotate.

[0024] The winding stem 16 has a crown 15 attached to one end and is connected to the movement 14 by being inserted through a through-hole formed in the case 112 of the watch case 11, thereby transmitting the rotational force of the crown 15 to the movement 14.

[0025] The inner frame 17 is a component that fixes the movement 14 in a predetermined position within the watch case 11 (casing 112), and in this embodiment, it is made of polyacetal resin. The inner frame 17 is positioned between the casing 112 and the movement 14, holding the movement 14 inside the watch case 11. By being positioned between the casing 112 and the movement 14, the inner frame 17 protects the movement 14 when the watch case 11 is subjected to impact. The inner frame 17 also suppresses rattling of the movement 14 during time setting. The inner frame 17 may be made of other resins such as polycarbonate resin or polyamide resin.

[0026] The structure of the clock 1 is not limited to the example shown in Figure 2. For example, the clock 1 may be equipped with a solar cell (not shown) used for light power generation. In this case, the solar cell may be placed between the dial 13 and the movement 14.

[0027] Figure 3 is a rear view of movement 14, Figure 4(a) is a perspective view showing the arrangement of some components of movement 14 from the rear side, (b) is a rear view of (a), (c) is a side view of (a), and (d) is a front view of (a).

[0028] Movement 14 includes a shift lever 141, a bolt 142, a barrel wheel 143, a date wheel 144, a battery 145, and a battery retaining plate 146, etc. The shift lever 141, the bolt 142, and the barrel wheel 143 are linked to the winding stem 16 and transmit the rotational force of the crown 15 to the date wheel 144. In detail, the winding stem 16 engages with the shift lever 141, the shift lever 141 engages with the bolt 142, the bolt 142 engages with the barrel wheel 143 when the position of the shift lever 141 changes with the movement of the winding stem 16 (crown 15), and the barrel wheel 143 engages with the date wheel 144. In this way, the rotational force of the crown 15 is transmitted to the date wheel 144.

[0029] In this embodiment, the battery 145 is a button cell and supplies power to the movement 14. The button cell is, for example, a silver oxide cell, an alkaline button cell, or a lithium coin cell.

[0030] The battery retaining plate 146 is a metal component positioned on the back cover 113 side of the movement 14, and in one example, is fixed to the movement 14 via screws. The battery retaining plate 146 restricts the movement of the battery 145. The battery retaining plate 146 also restricts the movement of the mandarin duck 141. In other words, the battery retaining plate 146 also serves as a restricting part that restricts the movement of the mandarin duck 141.

[0031] The battery retaining plate 146 has a battery restricting portion 1461 and a mandarin duck restricting portion 1462. The battery restricting portion 1461 is positioned between the movement 14 and the case back 113, and the battery retaining plate 146 is fixed to the movement 14 via screws, thereby pressing the battery 145 from the case back 113 side towards the dial 13 side. In this way, the battery restricting portion 1461 restricts the movement of the battery 145 toward the case back 113 side.

[0032] An example of a restricting part is the mandarin duck restricting part 1462, which is connected to the battery retaining plate 146 and restricts the movement of the mandarin duck 141. In other words, in this embodiment, the restricting part is integrally molded with the battery retaining plate 146. The mandarin duck restricting part 1462 is positioned between the mandarin duck 141 and the case back 113, and the battery retaining plate 146 is fixed to the movement 14 via screws, thereby pressing the mandarin duck 141 from the case back 113 side towards the dial 13 side. As a result, the mandarin duck restricting part 1462 restricts the movement of the mandarin duck 141 toward the case back 113 side.

[0033] Figure 5(a) is a perspective view of the inner frame 17 from the back side, (b) is a back view of the inner frame 17, (c) is a front view of the inner frame 17, and (d) is a cross-sectional view along the BB line shown in (b).

[0034] The inner frame 17 has a base portion 171, an outer peripheral portion 172, a plurality of protrusions 173, a plurality of openings 174, a pressing portion 175, and a groove portion 176. Each of these portions is integrally molded from resin. In other words, in this embodiment, the inner frame 17 and the pressing portion 175 are integrally molded from resin.

[0035] The base portion 171 is an annular part that serves as the base for the inner frame 17 and is positioned between the case 112 and the movement 14. The inner frame 17 is fixed in a predetermined position within the watch case 11 by the base portion 171 contacting the case 112 and the dial 13 (or the solar cell if the watch 1 is equipped with a solar cell).

[0036] The outer periphery 172 is a cylindrical portion that connects to the base portion 171 and is formed along the outer circumference of the movement 14. The outer periphery 172 houses the movement 14 inside and fixes the movement 14 in a predetermined position within the case 112. In this embodiment, the outer periphery 172 is formed in a substantially elliptical shape when viewed from above or from the bottom, but the shape of the outer periphery 172 only needs to be formed along the outer circumference of the movement, and may, for example, be formed in a circular shape when viewed from above or from the bottom. In the following description, unless otherwise specified, "when viewed from above or from the bottom" will simply be described as "when viewed from above".

[0037] The protrusions 173 are formed on the end face of the outer circumference 172 on the side facing the case back 113, and are flexible parts that protrude from the outer circumference 172 toward the case back 113. The protrusions 173 come into contact with the case back 113 when the case back 113 is attached to the case 112. In this embodiment, four protrusions 173 are formed. Specifically, each protrusion 173 is formed such that, when viewed from above, the distance between it and two other protrusions 173 that are not diagonally opposite each other is approximately equal. This makes it easier for each protrusion 173 to evenly receive the pressure from the case back 113 when the case back 113 is attached to the case 112.

[0038] In one example, the protrusion 173 is formed in a curved convex shape, but it does not have to be curved as long as it protrudes from the outer circumference 172 toward the back cover 113. Also, the number of protrusions 173 formed on the outer circumference 172 is not limited to four.

[0039] The opening 174 is formed on the outer circumference 172 at a position corresponding to the protrusion 173. In other words, the opening 174 is formed at a position that overlaps with the protrusion 173 when the inner frame 17 is viewed from above. In this embodiment, the same number of openings 174 as the protrusion 173 (four) are formed. The opening 174 is formed so that when the case back 113 is attached to the case body 112, the protrusion 173, along with the outer circumference 172, will bend due to the pressure from the case back 113. The opening 174 is formed so that the width of the inner frame 17 in the circumferential direction is wider than the width of the protrusion 173 in the circumferential direction. As a result, the protrusion 173 is more likely to bend together with the outer circumference 172 when the case back 113 is attached to the case body 112.

[0040] The pressing portion 175 is positioned between the case back 113 and the shidori regulating portion 1462, and presses against the shidori regulating portion 1462 when the case back 113 is attached to the case body 112. The pressing portion 175 is connected to the end face of the outer peripheral portion 172 on the case back 113 side and is positioned on the inside of the outer peripheral portion 172. As a result, when the case back 113 is attached, the pressing portion 175 contacts the surface of the shidori regulating portion 1462 on the case back 113 side and the surface of the case back 113 on the shidori regulating portion 1462 side. In other words, the pressing portion 175 comes into contact with the case back 113 and the shidori regulating portion 1462.

[0041] The pressing portion 175 extends between the side of the mandarin duck regulating portion 1462 facing the case back 113 and the side of the case back 113 facing the mandarin duck regulating portion 1462. More specifically, protrusions 1751 are formed on both the side of the pressing portion 175 facing the case back 113 and the side facing the mandarin duck regulating portion 1462. The height of the protrusion 1751 on the case back 113 side of the pressing portion 175 is such that when the case back 113 is mounted, the protrusion 1751 and the projection 173 come into contact with the case back 113. The height of the protrusion 1751 on the mandarin duck regulating portion 1462 side of the pressing portion 175 is such that when the inner frame 17 is mounted on the movement 14, the protrusion 1751 comes into contact with the mandarin duck regulating portion 1462. As a result, the pressing portion 175 can fill the gap between the back cover 113 and the shibori regulating portion 1462.

[0042] The pressing portion 175 is positioned so as not to overlap with the protruding portion 173 when the inner frame 17 is viewed from above. More specifically, the pressing portion 175 is positioned between the two protruding portions 173 that are close to the groove portion 176 when viewed from above. Furthermore, the pressing portion 175 is positioned so as not to overlap with the opening 174 when the inner frame 17 is viewed from above. More specifically, the pressing portion 175 is positioned between the two openings 174 that are close to the groove portion 176 when viewed from above.

[0043] When viewed from above, the pressing portion 175 is positioned so that the connection portion with the outer periphery 172 overlaps with the groove 176. As described later, the groove 176 is a groove through which the winding stem 16 passes, and the shibori 141 engages with the winding stem 16. Therefore, the distance between the portion of the pressing portion 175 that abuts against the shibori regulating portion 1462 and the portion of the pressing portion 175 that connects to the outer periphery 172 can be shortened. As a result, the pressing portion 175 can be formed with less material when extending from the end face of the outer periphery 172 on the back cover 113 side.

[0044] The groove 176 is a groove formed in the base portion 171 and the outer circumference portion 172 for passing the winding stem 16 through. The width of the groove 176 can be any width as long as the winding stem 16 can pass through, but it is preferable that it not be too wide from the viewpoint of maintaining the strength of the inner frame 17. In one example, the width of the groove 176 is less than the width of the crown 15 (winding stem 16) in a direction perpendicular to the axial direction of the crown 15.

[0045] Figure 6 is a reverse view showing the arrangement of some components of the movement 14 and its relationship to the central frame 17. The central frame 17 is shown with a dotted line to clarify the arrangement. Furthermore, to avoid clutter, Figure 6 shows the central frame 17 schematically, omitting the description of the protruding portion 173 and the opening 174.

[0046] As shown in Figure 6, the middle frame 17 is positioned so that the winding stem 16 passes through the groove 176. In this case, the pressing portion 175 is positioned to overlap with the shibori regulating portion 1462 when viewed from above. Also, the protrusion 1751 is positioned to overlap with the shibori regulating portion 1462 when viewed from above. Therefore, the pressing portion 175 (protrusion 1751) can press the shibori regulating portion 1462 when the back cover 113 is attached to the barrel 112. Furthermore, since the shibori regulating portion 1462 is positioned to overlap with the shibori 141 when viewed from above, it can also be said that the pressing portion 175 and the protrusion 1751 are positioned to overlap with the shibori 141 when viewed from above.

[0047] Figure 7(a) shows the arrangement of the back cover 113, the inner frame 17, and the battery retaining plate 146, focusing on region C shown in Figure 5(d). It is a schematic diagram of the back cover 113 being attached, and (b) is a schematic diagram of the back cover 113 after it has been attached. For the sake of explanation, in (a) and (b), the protruding portion 173 is shown as being directly above the outer peripheral portion 172 in the drawings.

[0048] As shown in Figure 7(a), when the case back 113 is attached to the case body 112, the pressing portion 175 and the multiple protrusions 173 come into contact with the case back 113. More specifically, the convex portion 1751 and the four protrusions 173 formed on the case back 113 side of the pressing portion 175 come into contact with the case back 113.

[0049] As shown in Figure 7(b), when the case back 113 is attached to the case 112, the pressing portion 175 and the four protrusions 173 flex toward the dial 13 (movement 14) due to the pressure from the case back 113. More specifically, the four protrusions 173 flex due to the pressure from the case back 113, and the convex portion 1751 formed on the side of the pressing portion 175 toward the shidori regulating portion 1462 presses the shidori regulating portion 1462 due to the pressure from the case back 113. Here, since the pressing portion 175 fills the gap between the case back 113 and the shidori regulating portion 1462, when the case back 113 is attached to the case 112, the pressing portion 175 can transmit the pressure from the case back 113 to the shidori regulating portion 1462. In other words, the pressing portion 175 can press the mandarin duck regulating portion 1462, including the pressure from the back cover 113.

[0050] The watch 1 of this embodiment is equipped with a winding stem regulating part 1462 (regulating part) positioned between the winding stem 141, which is engaged with the winding stem 16, and the case back 113, which restricts the movement of the winding stem 141. The inner frame 17 is positioned between the case back 113 and the winding stem regulating part 1462 and has a pressing part 175 that presses against the winding stem regulating part 1462. As a result, the watch 1 further presses the winding stem regulating part 1462, which restricts the movement of the winding stem 141 toward the case back 113, with the pressing part 175, thereby preventing the crown 15 from coming off together with the winding stem 16. In other words, the watch 1 can increase the fixing force of the winding stem 16. Furthermore, since the watch 1 has a pressing part 175 in which the inner frame 17 presses against the mandarin duck regulating part 1462, it is not necessary to prepare multiple movements 14 according to the shape of the watch case 11, and the versatility of the movement 14 can be maintained.

[0051] Furthermore, in watch 1, the inner frame 17 and the pressing part 175 are integrally molded from resin. Because the inner frame 17 and the pressing part 175 are integrally molded, when the pressing part 175 receives pressure from the case back 113, the inner frame 17 also receives that force, thus preventing the pressure from being applied only to the pressing part 175. In addition, because the pressing part 175 in watch 1 is made of resin, when pressed from the case back 113, the pressing part 175 deforms and compresses, making it easier to fill the gap between the case back 113 and the shibori regulating part 1462.

[0052] Furthermore, in watch 1, the inner frame 17 further has an outer peripheral portion 172 formed along the outer circumference of the movement 14, and the pressing portion 175 is positioned inside the outer peripheral portion 172. As a result, in watch 1, the outer peripheral portion 172 fixes the position of the movement 14, and both the outer peripheral portion 172 and the pressing portion 175 receive pressure from the case back 113, thus preventing the pressure from the case back 113 from being applied only to the pressing portion 175.

[0053] Furthermore, in watch 1, the inner frame 17 further has a plurality of flexible protrusions 173 that project from the outer periphery 172 toward the case back 113, and the pressing portion 175 is positioned so as not to overlap with the protrusions 173 when the inner frame 17 is viewed from above. In watch 1, because the inner frame 17 has a plurality of protrusions 173, the protrusions 173 and the pressing portion 175 receive pressure from the case back 113, and it is possible to suppress the pressure from the case back 113 from being applied only to the pressing portion 175. Also, in watch 1, because the pressing portion 175 is positioned so as not to overlap with the protrusions 173 when the inner frame 17 is viewed from above, it is possible to suppress the impact of the bending on the pressing portion 175 when the protrusions 173 are pressed by the case back 113 and bend together with the outer periphery 172.

[0054] Furthermore, in watch 1, the pressing portion 175 extends between the side of the case back 113 of the winding arm regulating portion 1462 and the side of the case back 113 of the winding arm regulating portion 1462. This makes it easier for watch 1 to fill the gap between the case back 113 and the winding arm regulating portion 1462, and further prevents the crown 15 from coming off together with the winding stem 16.

[0055] In the above-described embodiment 1, the restricting part that restricts the movement of the mandarin duck was a mandarin duck restricting part 1462 integrally molded with the battery retaining plate 146. However, any other component within the movement that restricts the movement of the mandarin duck toward the back cover 113 side may be used, such as a back retainer or a circuit block.

[0056] In the above-described embodiment 1, the inner frame 17 and the pressing portion 175 were integrally molded from resin. However, the pressing portion 175 may be molded separately from the inner frame 17 and joined to it. Known adhesive means can be used as appropriate for joining. For example, the inner frame 17 and the pressing portion 175 may be joined by adhesive bonding or adhesive tape bonding.

[0057] In the embodiment 1 described above, the pressing portion 175 had a protrusion 1751 that extended between the surface of the mantle-shaped regulating portion 1462 on the back cover 113 side and the surface of the back cover 113 on the mantle-shaped regulating portion 1462 side. However, the pressing portion 175 may not have a protrusion 1751, and instead may have a thickness sufficient to fill the gap between the back cover 113 and the mantle-shaped regulating portion 1462. In this case as well, the pressing portion 175 can fill the gap between the back cover 113 and the mantle-shaped regulating portion 1462 and press the mantle-shaped regulating portion 1462.

[0058] In the above-described embodiment 1, the inner frame 17 had a pressing portion 175. However, the pressing portion 175 may be formed on a member other than the inner frame 17, as long as it presses against the restricting portion that restricts the movement of the winding stem 141. In one example, the watch may have a pressing portion formed on the case back. In this case, the case back has a case back projection that protrudes toward the movement 14, and the case back projection may be positioned to correspond to the restricting portion (winding stem restricting portion 1462) when the case back is attached to the case 112, thereby forming a pressing portion. Even in this case, the watch can increase the fixing force of the winding stem 16 because the case back presses against the restricting portion.

[0059] Furthermore, the pressing portion 175 may not be joined to the inner frame 17 and may be a standalone pressing member. The pressing member may be made of the same resin as the inner frame 17 (polyacetal resin, polycarbonate resin, polyamide resin, etc.), or it may be made of a different resin than the inner frame 17. The pressing member is positioned between the back cover 113 and the regulating portion (duck-shaped regulating portion 1462) and presses against the regulating portion.
