Description

  The present invention relates to a connection structure between a watch band and a watch case.

Conventionally, there are various connection structures between a watch band and a watch outer case, but the connection structure between a metal band formed by a plurality of pieces or a flat leather band and a case includes a case body. A structure in which a spring bar is inserted into a band connecting part and a band provided on the side surface of the band (for example, Patent Document 1), and a structure in which a pin and a C ring are inserted into the band connecting part and the band (for example, Patent Document 2) Is.
In addition, in the case of a band called a bangle formed in an annular shape or a C shape (for example, Patent Document 3), the end of the band is often joined to the side surface of the trunk by brazing or the like.
That is, the band and the case are often directly connected, and the band is provided so as to protrude from the side surface of the trunk.

JP-A-8-332106 Japanese Utility Model Publication No. 5-94787 Utility model registration No. 3006073

In the case of the watch band connection structure as in Patent Documents 1 to 3, since the band is provided so as to protrude from the side surface of the case, the band and the watch body are independent in appearance.
Here, in the case of a bangle watch as disclosed in Patent Document 3, the case and the band may be connected such that the connecting portion of the case and the end of the band (bangle) have a continuous shape formed by a curve or the like. Although it may be preferable in terms of design, it may be difficult to design and manufacture the connecting portion depending on the connecting position of the band in the case. For example, if the band is to be connected to a position close to the back cover of the case, the back cover may be difficult to open or close.

In general, the height of the band is smaller than the height of the case, and the width of the band is smaller than the case diameter. Although it is necessary to squeeze the shape from the case side toward the band side, considering the space for inserting a jig for opening the back cover, the shape cannot be squeezed so much from the case toward the band side. In addition, when the back cover is fixed with screws, the case has a larger diameter due to the space where the screws are raised, so that it is more difficult to make the case and the band continuous. That is, when the band is connected to the case at the position of the back cover or in the vicinity of the back cover, there is a problem that the continuity between the case and the band is lost.
Here, it is conceivable that the case and the band are made continuous by using the back cover itself as a connecting member between the case and the band. However, a load is applied to the back cover at the time of impact, and the band is detached from the back cover. There is a possibility that. For this reason, the fixing structure of the back cover is limited.

  In view of the above problems, an object of the present invention is to provide a timepiece in which a case and a band can be connected in a continuous shape without hindrance to opening and closing of the back cover, and the back cover structure is not limited. .

  The timepiece of the present invention includes a case main body provided with a watch body, an exterior case having a back cover, a connecting member that is detachably fixed to the exterior case in a state of facing the back cover, and the connection member. And a band connected to the exterior case.

In this invention, since the connecting member is interposed between the outer case and the band, even if the case and the band are connected in a continuous shape so as to have a shape squeezed from the outer case side toward the band, the outer case The vicinity of the back cover is not so thin. That is, the back cover can be easily opened and closed by the jig while the connecting member is removed from the outer case while the outer case and the connecting member are connected in a continuous shape.
Here, the case main body and the band are connected via the connecting member, so that the case main body and the band can be formed in a continuous shape even if the case has a considerably larger diameter than the band diameter.
In addition, when the shape of the case main body or the band is changed, the structure in which the case main body is directly connected to the band needs to change the shape of the connection portion or the end of the band in the case main body. Then, it is only necessary to change the shape of the connecting member, so that the model development can be promoted.
Furthermore, since it is easier to form the band fixing portion on the connecting member than to form the band fixing portion on the case body, the band can be easily attached.

  In addition, since the connecting member faces the back cover in a state where the outer case and the band are connected, it is difficult for a load to be directly applied to the back cover during a drop impact or the like. Therefore, even when a back cover fixing structure having a low impact resistance compared to a screw back cover structure or the like, such as a dowel fixing structure, is employed, reliability against impact can be ensured. That is, the fixing structure of the back cover is not limited.

  In the timepiece of the present invention, it is preferable that the back cover has a dowel that fits into the opening of the case body.

According to the present invention, the dowel fixing structure is space-saving and the case main body does not increase in diameter, so that it is easy to form a continuous shape from the case main body to the band.
Further, as described above, since the back cover is difficult to be removed in the event of an impact, the effect of the present invention can be increased by adopting a dowel fixing structure with a relatively weak fixing force.

  In the timepiece according to the aspect of the invention, it is preferable that the band is curved substantially along an arm, and the case body and the connecting member are continuously curved in a curved shape of the band.

  According to this invention, since the entire timepiece has a continuous curved shape, the appearance design can be improved.

  In the timepiece of the present invention, it is preferable that the connecting member is gradually reduced in diameter from the outer case side toward the band side.

In this invention, the diameter of the band at the position facing the back cover in the exterior case and the diameter of the band are such that the diameter of the band is often smaller, and the connecting member has a reduced diameter. . That is, the exterior case and the band can be easily connected in a continuous shape via the connecting member.
The cross-sectional shapes of the band and the connecting member are appropriately determined such as a circle, an ellipse, and a polygon.

  In the timepiece of the present invention, it is preferable that an axial direction of the timepiece connecting the time display portion of the timepiece and the case back intersects a bending direction of the case body.

  When the axial direction of the watch body (movement) is substantially along the bending direction of the case body, the time display unit (the dial plate or the display panel) is oriented in the direction substantially along the arm, but as in the present invention. In addition, since the axial direction of the watch body intersects the bending direction of the case main body, it is possible to provide the case main body so that the time display portion can be easily seen.

  In the timepiece of the present invention, the back cover has a dowel that fits into the opening of the case body, and a part of the outer periphery of the back cover is the case on the inner peripheral side of the curved shape of the case body. It is preferable to be exposed from the main body.

  According to this invention, since a part of outer peripheral part of a back cover is exposed from a case main body, it is easy to pry off a back cover. Here, since the position where the outer peripheral part of the back cover is exposed is the arm side and is not conspicuous, the appearance design can be improved.

  In the timepiece of the present invention, the connecting member is formed with a protruding portion that protrudes toward the back cover, and at least part of the case body around the back cover protrudes toward the connecting member. A protruding portion is formed, and the connecting member and the case main body are fixed by a fixing member inserted into the protruding portion of the connecting member and the protruding portion of the case main body in a direction substantially along the back cover. It is preferable.

According to the present invention, the case main body and the connecting member can be easily connected by inserting the fixing member such as a screw or a spring bar into the protruding portion of the connecting member and the protruding portion of the case main body not facing the protruding portion. Can be fixed.
In addition, since the protrusions of the connecting member are close to the back cover in a state where the protrusions are fixed to each other, impact resistance can be improved.

  In the timepiece of the present invention, a concave portion into which a convex portion formed at an end portion of the band is inserted is formed at an end portion on the band side of the coupling member, and the coupling member and the case body are It is fixed by a fixing member that is inserted from the bottom of the recess toward the case body, and the connection member and the band are inserted into the connection member and the protrusion with the protrusion inserted in the recess. It is preferable that the fixing member is fixed.

In this invention, the convex part of a band is inserted in the recessed part into which the fixing member of a connection member and a case main body is inserted. That is, since the concave portion of the connecting member is used both for connecting the connecting member and the case main body and for connecting the connecting member and the band member, the space efficiency can be increased.
In addition, if a concave portion is formed at the end of the band and a convex portion is formed at the end of the connecting member on the band side, the fixing member of the band and the connecting member is exposed on the surface after finishing the band. However, the fixing member is not exposed on the band surface after finishing by forming the convex portion at the end portion of the band and the concave portion at the end portion on the band side of the connecting member as in the present invention. Thereby, since it becomes possible to fix a band and a connection member after finishing of the band surface, workability | operativity improves.

  Here, as described above, in the case where the connecting member and the case main body are fixed by the fixing member inserted into the protruding portion of the connecting member and the protruding portion of the case main body in the direction substantially along the back cover. Since the connecting member and the case main body are fixed in two directions, a direction substantially along the back cover and a direction crossing the back cover, the impact resistance can be further increased.

  According to the present invention described above, it is possible to provide a timepiece in which the outer case and the band can be connected in a continuous shape without hindering the opening and closing of the back cover, and the back cover structure is not limited.

Comes off the case body 11.

According to this embodiment, the following effects can be obtained.
(1) Since the connecting member 20 is interposed between the outer case 10 and the band member 30, even if the outer case 10 and the band member 30 are connected in a continuous shape, the vicinity of the back cover 12 of the outer case 10 It will not be so thin. That is, the back cover 12 can be easily opened and closed by the jig while the connecting member 20 is detached from the outer case 10 while connecting the outer case 10 and the connecting member 20 in a continuous shape.

(2) Since the connecting member 20 faces the back cover 12 in a state in which the exterior case 10 and the band member 30 are connected, it is difficult for a load to be applied directly to the back cover 12 during a drop impact or the like. Hard to come off from 10. Thereby, the reliability with respect to an impact is securable.
Further, since the back cover 12 has a space-saving dowel fixing structure, the case body 11 does not increase in diameter. For this reason, it is possible to easily form a continuous shape from the case main body 11 to the band member 30.

(3) When the shape of the case main body 11 or the band member 30 is changed, in the structure in which the case main body is directly connected to the band member, it is necessary to change the shape of the connection part in the case main body or the end of the band member. On the other hand, in this embodiment, since the shape of the connecting member 20 may be changed, model development can be promoted.

(4) Since it is easier to form the fixing part (such as the recess 22) of the band member 30 on the connecting member 20 than to form the fixing part of the band member 30 on the case main body 11, the band member 30 can be easily attached. it can.

(5) Since the case main body 11 and the connecting member 20 are continuously curved in the curved shape of the band member 30, the appearance design of the timepiece can be improved.

(6) Since the connecting member 20 is gradually reduced in diameter from the outer case 10 side toward the band member 30 side, the outer case 10 and the band member 30 are easily connected in a continuous shape via the connecting member 20. can do.

(7) Since the axial direction S of the movement 100 intersects the bending direction R of the case main body 11 and the dial 101 and the pointer 102 face upward with respect to the direction along the arm, the time is visually recognized. Can be improved.

(8) Since the stepped portion 122 of the back cover 12 is exposed to the outside from the notch 113 of the case body 11, the back cover 12 can be easily removed. Here, the position where the stepped portion 122 is exposed is on the side facing the arm (in the 6 o'clock direction) and is not conspicuous, so the appearance design can be improved.

(9) The case main body 11 and the connecting member 20 can be easily fixed by inserting the screw 25 into the connecting member protruding portion 21 and the case main body protruding portion 111 that does not face the connecting member protruding portion 21.
In addition, since the connecting member protruding portion 21 is close to the back cover 12 in a state where the connecting member protruding portion 21 and the case main body protruding portion 111 are fixed, impact resistance can be improved.

(10) The convex portion 311 of the band member 30 is inserted into the concave portion 22 into which the screw 26 for fixing the connecting member 20 and the case main body 11 is inserted, and the concave portion 22 of the connecting member 20 is connected to the connecting member 20 and the case main body 11. Therefore, the space efficiency can be increased.

(11) The protrusion 311 is formed at the end of the band member 30, and the recess 22 is formed at the end of the connecting member 20 on the band member 30 side, whereby a screw is formed on the surface of the skin material 32 of the band member 30. The band member 30 and the connecting member 20 can be fixed without being exposed. That is, since the band member 30 and the connecting member 20 can be fixed after the skin material 32 is wound around the core material 31, workability is improved.

(12) Since the connecting member 20 and the case main body 11 are fixed in two directions by a screw 25 provided in a direction substantially along the back cover 12 and a screw 26 provided in a direction intersecting the back cover 12, Higher impact resistance can be achieved.

[Modification of the present invention]
The present invention is not limited to the above-described embodiment, and various improvements and modifications can be made within the scope of solving the problems of the present invention.
In the above embodiment, the connecting member 20 and the case main body 11 are fixed by the two screws 25 as shown in FIG. 11, but the fixing member between the connecting member 20 and the case main body 11 is not limited to a screw. For example, as shown in FIG. 12, the connecting member 20 and the case main body 11 are fixed by a pin 41 provided in a through hole 40 formed in the case main body 11 and the connecting member 20 and a pipe 42 having a C-shaped cross section. Also good. The pipe 42 is disposed at one end of the case body 11 in the through hole 40, and the pin 41 and the pipe 42 are fixed in the through hole 40 by press-fitting the pin 41 into the pipe 42.
Further, the connecting member 20 and the case main body 11 may be fixed by the screw pins 43 as shown in FIG.

  FIG. 14 shows an outer case 45 and a connecting member 46 having shapes different from those of the above embodiment. The exterior case 45 and the connecting member 46 of this example have a substantially rectangular cross section. Since the structures of the exterior case 45 and the connecting member 46 are configured in substantially the same manner as the structures of the exterior case 10 and the connecting member 20 of the above-described embodiment, description thereof is omitted. The connecting member 46 is preferably connected to a band member having a square cross section. Thereby, like the timepiece of the above embodiment, the entire timepiece has a continuous curved shape, so that the appearance design can be improved.

The back cover fixing structure in the embodiment is a dowel biting structure, but the back cover fixing structure is not limited to this, and any fixing structure can be adopted. In the present invention, since the connecting member is interposed between the exterior case and the band, the case does not become so thin that the back cover goes into the back of the case, and a space for inserting a jig for opening the back cover is secured. Therefore, it is possible to employ a screw back cover fixing structure that is screwed into a female screw formed in the opening of the case body. A groove for engaging a jig is formed in the outer peripheral edge of the screw back cover, and the back cover can be opened and closed by engaging the jig in this groove and rotating the back cover.
Moreover, it is good also as a structure where a back cover is fixed to a case main body with a screw. In this case, the case body has a large diameter corresponding to the space for raising the screw, but by connecting the connecting member to an appropriate length and reducing the diameter from the outer case side to the band side, the outer case to the band can be smooth. A continuous shape can be obtained.

Although the best configuration for carrying out the present invention has been specifically described above, the present invention is not limited to this. That is, the invention has been illustrated and described primarily with respect to particular embodiments, but may be configured for the above-described embodiments without departing from the scope and spirit of the invention. Various modifications and improvements can be made by those skilled in the art in terms of materials, quantity, and other detailed configurations.
The description limited to the shape, material, etc. disclosed above is an example for easy understanding of the present invention, and does not limit the present invention.
