Description

Wearing structure and the clock of the belt

technical field

The present invention relates to a belt mounting structure and a timepiece.

Background technique

Conventionally, as a structure for attaching a band to a case of a timepiece or the like, a structure in which the band is fixed to the case using a spring bar is known.

For example, Patent Document 1 discloses a structure including a cylindrical member, a pair of pins provided at the end of the cylindrical member so as to be able to advance and retreat along the axial direction of the cylindrical member, and a pin disposed inside the cylindrical member. And to the urging member that urges the pin in the forward direction that makes the pin protrude from the end of the cylindrical member, the rear of the pin is at least equipped with a spring bar (connecting member), and the spring bar is configured to pass through the pin from the cylindrical member. The locking part at the position where the end part of the pin is away from the stroke of the pin is locked to prevent the pin from detaching from the cylindrical member, and the band is mounted on the watch case by using the spring bar.

In the structure described in Patent Document 1, compared with the case where the spring bar does not have such a structure, the effect of increasing the strength of the spring bar against a load such as when the timepiece is dropped and impacted can be expected.

prior art literature

Patent Document 1: Japanese Patent Laid-Open No. 2007-89882

However, as in the structure described in Patent Document 1, when the spring bar is in direct contact with the case and the band, when a strong impact is applied to the case or the band when the timepiece is installed or dropped, the shock will Pass directly to the spring bar. In particular, when shocks are applied in the direction in which the case and the belt approach or separate, in the direction in which the case and the belt twist each other, or when the product is used in an environment where high-frequency and high-amplitude vibrations are repeatedly applied, etc. , a larger impact is applied to the part of the spring bar that connects the housing and the belt.

In addition, in order to reflect the high-end sense of clocks, etc., the casing and the band are not formed of resin or the like but are formed of a metal material. However, when the casing and the band are formed of a metal material, it is not very possible to move the belt on the side of the casing and the band. Absorbs shocks, so shocks applied directly to the spring bar are greater.

In this case, simply providing a shock-absorbing structure in the spring bar like the structure described in Patent Document 1 cannot sufficiently prevent damage to the spring bar or the risk of the belt falling off when the spring bar is removed.

In a state where the strap 2 is attached, the cushioning member 3 holds the connecting joint 20 at a predetermined position of the strap attaching portion 15 of the timepiece case 10 .

In the present embodiment, the second fitting portion 30 has a convex portion 32 protruding in the direction in which the belt 2 extends (the vertical direction in FIG. 1 ). As mentioned above, the convex part 32 is accommodated in the concave part 22 of the 1st fitting part 23, and has the shape fitted into it.

A second through hole 33 extending in the width direction of the belt 2 (horizontal direction in FIG. 1 ) is formed in the second fitting portion 30 (in this embodiment, the convex portion 32 constituting the second fitting portion 30 ).

In the fitting state where the connecting joint body 20 and the buffer member 3 are fitted, the second through hole 33 communicates with the first through hole 25 , and in this communicating state, the first through hole 25 and the second through hole 33 are inserted into the second through hole 33 . Through the spring rod 4. In addition, the second through hole 33 in this embodiment is arranged such that its center is offset to the outside of the belt attachment direction (that is, the side opposite to the side facing the timepiece case 10 ) from the center of the first through hole 25 . moved position.

In this embodiment, the inner diameter of the second through hole 33 is substantially the same as the outer diameter of the spring rod 4 , and the spring rod 4 is fitted into the second through hole 33 with substantially no play.

In addition, in the second fitting portion 30 (in this embodiment, the convex portion 32 constituting the second fitting portion 30 ), a second through hole 33 is formed along the width direction of the belt 2 (lateral direction in FIG. 1 ). ) Extended second shaft hole 34.

As described above, in the fitting state where the connecting joint body 20 and the cushioning member 3 are fitted, the second shaft hole 34 communicates with the first shaft hole 26 formed in the first fitting portion 23 to constitute a coupling shaft. A connected shaft hole into which part 51 (see FIG. 4 etc.) is inserted.

The spring bar 4 is a rod-shaped member inserted through the first through hole 25 and the second through hole 33 . The spring rod 4 includes, for example, a cylindrical member, a pair of pins provided at both ends of the cylindrical member so as to be able to move forward and backward along the axial direction of the spring rod 4, and a pair of pins that are mounted on the inside of the cylindrical member toward the outside of the cylindrical member. The spring (all not shown) of applying force.

The spring bar 4 inserts one pin into the belt mounting hole 152 of the belt mounting part 15 in a state of passing through the first through hole 25 and the second through hole 33 formed on the belt side, and makes the other pin The band 2 is connected to the timepiece case 10 by being inserted into the other band attachment hole 152 while being temporarily pressed into the interior of the cylindrical member against the spring force.

As described above, the front end portions 41 on both sides of the spring bar 4 are tapered, and the belt attachment hole 152 becomes deeper toward the center in accordance with the shape of the front end portions 41 of the spring bar 4 . Thus, when the front end portion 41 of the spring bar 4 is inserted into the belt attachment hole 152 , the front end portion 41 of the spring bar 4 is stably held in the center portion of the belt attachment hole 152 .

In the present embodiment, the strap attachment structure is constituted by the strap attachment portion 15 on the side of the watch case 10 in which the strap attachment hole 152 is penetratingly provided on the opposing surfaces of the two leg portions; , which has a first fitting portion 23 formed with a first through hole 25 extending in the width direction of the belt 2, and is mounted to the belt mounting portion 15; a buffer member 3, which has a second fitting portion 30, the second The fitting part 30 can be fitted with the first fitting part 23 and is formed with a second through hole 33 communicating with the first through hole 25 in the fitted state; The two through holes 33 are passed through, and when the band 2 is attached to the watch case 10 , both ends are respectively inserted into the band attaching holes 152 of the band attaching portion 15 .

Next, with reference to FIG. 4 , FIG. 5( a ) and FIG. 5( b ), the belt attachment structure and the action of the timepiece according to this embodiment will be described.

FIG. 4 is an exploded perspective view showing a structure in which the connecting joint body 20 and the cushioning member 3 are integrated in the present embodiment.

5( a ) and FIG. 5( b ) are main part side views illustrating how the integrated connecting joint body 20 and buffer member 3 are attached to the strap attachment portion 15 of the watch case 10 .

When assembling the timepiece 100 by attaching the band 2 to the timepiece case 10, first, as shown in FIG. The convex part 32. At this time, the connecting joint body 20 and the cushioning member are arranged so that the first shaft hole 26 formed in the first fitting part 23 and the second shaft hole 34 formed in the second fitting part 30 form a single continuous shaft hole. 3 for counterpoint.

And, in the state where the first shaft hole 26 and the second shaft hole 34 form one continuous shaft hole, the coupling shaft member 51 is inserted from the side formed as the small-diameter portion 26a toward the other side, and the shaft member 51 is inserted from the side formed as the large-diameter portion 26a. 26b is inserted into the C-shaped ring 52, and the C-shaped ring 52 is fitted into the insertion-side front end of the coupling shaft member 51. Thereby, the connection joint body 20 and the cushioning member 3 are integrated.

Furthermore, the spring bar 4 is inserted into the first through hole 25 formed in the first fitting portion 23 and the second through hole 33 formed in the second fitting portion 30 .

As described above, since the inner diameter of the second through hole 33 is substantially the same (equal to) the outer diameter of the spring bar 4 , the spring bar 4 is arranged in a state of being closely attached to the second through hole 33 . On the other hand, since the inner diameter of the first through hole 25 is formed larger than the outer diameter of the spring bar 4 , the spring bar 4 is arranged with a play with respect to the first through hole 25 of the connection joint body 20 .

In this embodiment, before the spring bar 4 is attached to the belt mounting part 15, as shown in FIG. The center of the first through hole 25 is further shifted to the outside in the band mounting direction (ie, the side opposite to the side facing the timepiece case 10 ).

Next, the integrated connecting joint body 20 and the buffer member 3 are disposed between the two leg portions 151 of the band attachment portion 15 of the timepiece case 10 . At this time, as shown in FIG. 5( a ), the end surfaces of the second fitting portion 30 and the protruding portion 31 of the shock absorbing member 3 are arranged to face the side surface of the timepiece case 10 .

Then, the front end portion 41 of the spring bar 4 inserted through the first through hole 25 and the second through hole 33 is inserted into the belt attachment hole 152 formed in the leg portion 151 of the belt attachment portion 15 .

Then, the other end portion 41 of the spring bar 4 is inserted into the belt attachment hole 152 formed in the other leg portion 151 of the belt attachment portion 15 while being pushed in. At this time, the cushioning member 3 is pressed and shrunk by pressing and fitting the joint joint body 20 and the cushioning member 3 toward one side of the timepiece case 10 (in the direction indicated by the arrow in FIG. 5( a )). And when the front end portion 41 on the other side of the spring bar 4 is inserted into the belt mounting hole 152 on the other side of the belt mounting portion 15, as shown in FIG. The center of the second through hole 33 is moved to a position substantially coincident with the center of the first through hole 25 .

The spring bar 4 is pressed by the spring force and expands along the width direction of the band 2, so that the front ends 41 on both sides of the spring bar 4 are respectively locked in the band mounting portion 15, thereby completing the installation of the band 2 to the watch case 10 .

As mentioned above, since the axial center of the spring bar 4 and the center of the first through hole 25 approximately coincide with each other in the belt-mounted state, it becomes approximately between the spring bar 4 and the first through hole 25 with respect to the outer circumference of the spring bar 4 . A state where play is evenly provided (see FIG. 5(b)).

Furthermore, as shown in FIG. Therefore, unless a strong force such as greatly crushing the shock absorbing member 3 is applied, the connecting joint body 20 does not come into contact with the timepiece case 10 .

As described above, according to the present embodiment, the second fitting portion 30 of the buffer member 3 formed with the second through hole 33 is fitted to the first fitting portion 23 of the coupling node 20 formed with the first through hole 25 . , the spring bar 4 is inserted through the first through hole 25 and the second through hole 33, and is arranged between the two legs 151 of the belt mounting part 15 on the watch case 10 side, and the front end 41 of the spring bar 4 The band 2 is attached to the timepiece case 10 by engaging with the band attachment hole 152 provided through the opposing surface of the leg portion 151 . Moreover, the inner diameter of the second through hole 33 is the same as the outer diameter of the spring bar 4, whereas the inner diameter of the first through hole 25 is formed larger than the outer diameter of the spring bar 4, and the spring bar 4 has Configured with play.

Thus, in a state where no impact or the like is applied to the timepiece case 10 or the band 2, or even if an impact or the like is applied, the impact can be absorbed within the range of elastic deformation of the cushioning member 3, the spring The rod 4 is not in contact with the connecting node body 20 , and the impact or the like applied to the belt 2 is not directly transmitted to the spring rod 4 . In addition, shocks and the like applied to the timepiece case 10 are also absorbed by the cushioning member 3 in contact with the timepiece case 10 . Therefore, when an impact or the like is applied to the watch case 10 or the band 2, the impact or the like transmitted to the spring bar 4 is attenuated to prevent breakage of the spring bar 4 and falling off of the band 2, thereby improving the impact resistance of the timepiece 100, Vibration resistance.

In addition, in this way, the spring bar 4 is arranged with play with respect to the connecting node body 20, but since the spring bar 4 is inserted into the first through hole 25 of the connecting node body 20, when the timepiece case 10 and the belt 2 are applied, When the buffer member 3 cannot completely absorb such a large impact, the spring bar 4 abuts against the first through-hole 25 of the connecting joint body 20 to lock it. Thereby, it is possible to reliably prevent the belt 2 from coming off.

In addition, the second fitting portion 30 has a convex portion 32 protruding in the extending direction of the belt 2 , and the first fitting portion 23 has a concave portion 22 having a shape that receives the convex portion 32 . Thereby, positioning can be easily performed only by fitting the convex part 32 and the recessed part 22, and assembly of components becomes easy.

In addition, shaft holes 26 and 34 communicating in the fitted state are formed in the first fitting portion 23 and the second fitting portion 30 , and the connecting joint body 20 and the cushioning member 3 are coupled through the shaft holes 26 and 34 . It is integrated with the shaft member 51 . As described above, since the connecting joint body 20 and the cushioning member 3 are integrated, the assembly of the band 2 to the timepiece case 10 becomes easy.

In addition, instead of using the spring bar 4 for attaching the band 2 to the watch case 10, the connecting joint body 20 and the buffer member 3 are integrated using a coupling shaft member 51 which is a different member, thereby holding the spring bar 4 This is a state where there is play with respect to the connecting joint body 20 . Therefore, it is possible to prevent an impact or the like applied to the belt 2 from being transmitted to the spring bar 4 via the connection joint body 20 .

In addition, the shock can be absorbed by the amount of elastic deformation of the cushioning member 3 , and a sufficient width for cushioning by the cushioning member 3 can be ensured.

In addition, since the surface of the buffer member 3 facing the timepiece case 10 protrudes toward the timepiece case 10 side than the surface of the connecting joint body 20 facing the timepiece case 10, it is possible to prevent the force applied to the timepiece case 10 Shock and the like are directly transmitted to the belt 2 side. In particular, when the watch case 10 and the band 2 (connecting nodes 20 constituting the band 2 ) are both formed of metal materials, it is possible to prevent the metals from colliding directly with each other and rubbing against each other, thereby preventing the watch case 10 and the band 2 from colliding with each other. damaged or broken.

In addition, in the present embodiment, when the band 2 is attached to the timepiece case 10, the spring bar 4 is fitted while the buffer member 3 is pressed and shrunk. Therefore, when the belt 2 is detached from the watch case 10, if the one front end 41 of the spring bar 4 is detached from the belt mounting hole 152, the cushioning member 3 will move toward the watch from the watch due to the restoring force of returning to the original shape. The strip 2 is squeezed in the direction in which the housing 10 is removed. Thereby, the belt can be detached relatively easily.

In addition, when the belt 2 including the joint body 20 and the watch case 10 are formed of a metal material, by arranging the cushioning member 3 formed of a material having a texture different from that of metal, such as urethane resin or silicone rubber, it is possible to realize The lightweight appearance and design are different from clocks made of only metal materials.

In addition, in this embodiment, the case where the second fitting part 30 of the cushioning member 3 has the convex part 32 and the first fitting part 23 of the connection node 20 has the concave part 22 of the shape which receives this convex part 32 was shown as an example. , but the shapes of the first fitting portion 23 and the second fitting portion 30 are not limited thereto.

Either one of the first fitting portion 23 and the second fitting portion 30 may have a convex portion, and the other may have a concave portion in a shape that receives the convex portion 32 , or it may be configured such that the first fitting portion of the joint body 20 is connected. 23 has a convex portion, and the second fitting portion 30 of the cushioning member 3 has a concave portion in a shape that receives the convex portion.

In addition, in this embodiment, the case where the coupling joint body 20 and the cushioning member 3 are integrated using the joint shaft member 51 and the C-ring 52 is shown as an example, but the structure in which the coupling joint body 20 and the cushioning member 3 are integrated Not limited to this.
