Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band whose entire length can be adjusted when it is worn on a part of the body, and more particularly to a band suitable for attaching a watch to the part of the body and the use thereof. It was about a watch with a band.

[0002]

BACKGROUND ART Conventionally, a bracelet-type band in which a plurality of pieces formed of metal or the like are connected has been used as a wristwatch or an accessory. Such a band may be provided with a length adjusting mechanism for adjusting the entire length. The length adjusting mechanism includes a coarse length adjusting mechanism for relatively roughly adjusting the length by attaching and detaching one or a plurality of pieces, and a clasp provided on the band for attaching and detaching the band. In addition, a length fine adjustment mechanism or the like, which allows the end portion of the band main body to be attached so that the position can be changed and relatively finely adjusts the length, is often used.

As an example thereof, FIG. 9 shows a length fine adjustment mechanism 92 provided in the clasp 91. In FIG. 9, the clasp 91 is provided with a cover member 93 having a U-shaped cross section. The cover member 93 is provided with a pair of flanges 95 extending in the longitudinal direction of the band 94 and facing each other. A plurality of sets of engagement holes 96 are formed in these flanges 95 at positions facing each other along the longitudinal direction of the band 94. A spring rod 97 inserted through the end of the band 94 main body can be engaged with any of a plurality of engagement holes 96 provided by changing the engagement hole 96 for retaining the spring rod 97. The length of the band 94 is adjustable. For example, if one of the plurality of sets of engagement holes 96 is selected according to the thickness of the arm to be worn, the length of the band 94 is adjusted appropriately and the band 94 is fitted to the arm. be able to.

[0004]

In such a length fine adjustment mechanism 92, a spring rod 97 is used to attach the end of the body of the band 94 to the cover member 93. However, a special tool such as so-called “spring bar removal” is required, and there is a problem that the user himself cannot easily perform fine adjustment of the band length. If the spring rod 97 is not used for attachment / detachment, when the spring rod 97 is attached / detached from / to the cover member 93, the spring rod 97 suddenly flies due to the elastic force of the spring provided inside the spring rod 97, There is also a problem that the spring rod 97 is easily lost.

On the other hand, Japanese Patent Laid-Open No. 2001-509408 discloses a fine length adjusting mechanism which allows the user to easily fine adjust the length of the band. Since the number of parts is large and the structure is complicated, precision is required for processing each part, and assembly work and finishing work are complicated, so that the production efficiency is not good, and especially expensive titanium alloy etc. There is a problem that the production cost rises when the material is adopted. Also,
Since it is a structure that combines many parts intricately, sweat that has entered between the parts does not easily escape from between the parts,
Since it is easy to corrode parts, form parts with corrosion resistant materials or apply corrosion resistant gold plating etc.
It is necessary to secure sufficient corrosion resistance, and from this point as well, there is a problem that the production cost rises.

It is an object of the present invention to provide a band having a simple structure and a simple structure with a small number of parts and a watch with a band using the band.

[0007]

The first invention of the present invention comprises a plurality of constituent members connected in the longitudinal direction thereof and an adjusting mechanism for adjusting the entire length, and among the plurality of constituent members, A band in which a pair of constituent members to be connected to each other are connected to each other via the adjusting mechanism, and the adjusting mechanism includes a turning link and a connecting link whose tip ends are turnably connected to each other. The rotating link and the connecting link can be changed from one of the folded state in which they overlap with each other and the extended state in which their base ends are separated from each other to the other state. Is rotatably attached to one of the component members of the rotary shaft through a rotary shaft, and has a shaft exposed portion that exposes a part of the rotary shaft that is inserted inside. The locking protrusion is attached to the other of the pair of constituent members so as to be rotatable, and has a locking projection for locking the side surface of the rotation shaft, and the locking projection passes through the shaft exposed portion when in the folded state. It is characterized in that it is provided at a position where it engages with the rotating shaft.

In the present invention as described above, the lengths of the rotating link and the connecting link are changed in two steps by changing the rotating link and the connecting link from one of the folded state and the extended state to the other. Therefore, the total length of the band can be finely adjusted in two steps. Further, when one of the rotation link and the connection link is rotated with respect to the other so as to be in the folded state, the locking projection engages with the rotation shaft and is locked to the rotation shaft, so that tension or the like is generated. Even if an external force is applied, if one of the rotation link and the connection link does not rotate with respect to the other, the engagement between the locking protrusion and the rotation shaft is not released, and the folded state is maintained, The link and the connecting link do not unexpectedly shift from the folded state to the spread state.
On the other hand, by manually rotating one of the rotation link and the connection link with respect to the other, the engagement between the locking projection and the rotation shaft can be easily released, so that the length adjustment operation is performed exclusively. It can be done easily without the use of tools. Since only tension is usually applied as an external force to each part of the band,
The rotating link and the connecting link as described above do not shift from the spread state to the folded state by an external force, and
Once in the extended state, the extended state is maintained, and therefore a mechanism for maintaining the folded state is not necessary. Moreover, the adjusting mechanism can be configured if the rotary link and the connecting link and the shafts such as the rotary shaft for connecting the rotary link and the connecting link to each other or the constituent members are provided. Even if the mechanism is provided, the number of parts does not increase, the structure of the entire band does not become complicated, and the manufacturing cost of the band can be reduced.

In the band as described above, the band includes a plurality of metal pieces connected to each other, and a clasp having an end member, an intermediate member, and a cover member foldably connected to each other in a Z shape. A piece provided at the end of a plurality of connected pieces as the pair of constituent members to be connected to each other, wherein the piece, the end member, the intermediate member and the cover member are provided as the constituent members. And a cover member connected to the cover member via the adjusting mechanism. By applying the present invention to such a band, it becomes possible to easily adjust the length of a metal bracelet type band, and even if the wearing part of the body becomes slightly thick due to swelling etc., it can be adjusted by the adjusting mechanism. By increasing the total length of the band, the feeling of pressure caused by wearing a cramped band is eliminated, and a comfortable feeling of wearing can always be maintained.

Further, in the above-mentioned band, the rotation link includes a pair of outer piece portions arranged at side edge portions of the band, and a connecting portion connecting these outer piece portions to each other.
Each of the pair of outer piece portions is provided with a rotation shaft insertion hole through which the rotation shaft is inserted and a connection shaft insertion hole through which a connection shaft for rotatably connecting the connection link is inserted. ,

The shaft exposing recessed part is the shaft exposing part for exposing a part of the rotating shaft, and the connecting link is A connecting shaft disposed between the pair of outer piece portions of the rotating link and extending in the longitudinal direction, the connecting shaft having an insertion hole through which the connecting shaft is inserted at one end of the connecting link. An insertion tube portion is provided, and a fixed shaft insertion tube portion having an insertion hole through which a fixed shaft for rotatably connecting to the other of the component members is inserted is provided at the other end of the connection link. The connecting shaft insertion tubular portion and the fixed shaft insertion tubular portion are connected by a connecting wall portion in which a recessed portion for receiving the shaft is formed, and the recess portion for receiving the shaft is inside the folded state when the folded state. The rotating shaft is housed, and the connecting shaft is inserted. It is preferable that the locking projection is provided on the outer circumferential surface of the part. With this configuration, when the turning link and the connecting ring are overlapped with each other and they are in the folded state, the connecting link is arranged between the outer piece portions of the turning link, and the shaft receiving recess of the connecting ring is provided. Since the rotating shaft is housed, the thickness is small even in the folded state, and the whole is compact. For this reason, it is possible to provide an adjusting mechanism inside the cover member provided in the middle clasp with three folds or in the double door, and if the adjusting mechanism is provided inside the cover member, the rotation link, the connecting ring, etc. Because it is hidden by the cover member and disappears,
The appearance of the band will be excellent in terms of design.

In such a band, the rotating shaft includes a pipe portion formed in a tubular shape, a pin provided at an end of the pipe portion so as to be able to move forward and backward, and a spring for urging the pin outward. It is desirable that the spring rod is equipped with. By doing so, the adjusting mechanism can be formed by using a general-purpose component such as a spring rod, and also from this point, the manufacturing cost of the band can be reduced. In addition, since the turning link can be easily attached to and detached from the cover member, when the band is a watch band, when the turning link is removed from the cover member when disassembling the watch, the band can be removed from the left and right sides of the watch. Can be divided into
Since the back side of the watch can be opened, the convenience of disassembling the watch can be achieved.

At this time, the connecting shaft inserting tubular portion itself is a cylindrical one, and the locking projection is a cam which is a part of the cylindrical peripheral surface of the connecting shaft inserting tubular portion protruding. It is preferable that the spring rod has a profile in which the spring rod is gradually elastically deformed by a rotating operation of the connecting shaft insertion tube portion. With this configuration, both the rotating operation for engaging the cam with the spring rod and the rotating operation for releasing the engagement between the cam and the spring rod can be smoothly performed with a small force. In addition to improving the feeling, the wear of the contacting parts of the cam and the spring rod is reduced, and the spring rod is not deformed by force, so the durability of the adjusting mechanism for adjusting the length is improved. be able to.

Further, in the above-mentioned band, a watch band for mounting the watch on the wrist can be adopted as the band. If the present invention is applied to such a watch band, even if the thickness of the arm changes due to physical condition or the like, the entire length of the band can be adjusted by the adjusting mechanism. When the link is in the folded state, the band fits to the arm, a comfortable fit can be always maintained, and inconveniences such as the timepiece turning behind the arm are avoided.

A second aspect of the present invention is a timepiece with a band provided with a band to be worn on a part of the body, wherein the band has a plurality of structural members connected in the longitudinal direction thereof and an entire length. Adjusting mechanism for adjusting the height, a pair of constituent members to be connected to each other among the plurality of constituent members are connected to each other via the adjusting mechanism, and the adjusting mechanism has tips with respect to each other. A pivotal link and a coupling link that are rotatably coupled to each other are provided, and the pivotal link and the coupling link can change their state from one of a folded state in which they overlap with each other and a spread state in which their base ends are separated from each other. The rotation link has a base end rotatably attached to one of the pair of constituent members via a rotation shaft and exposes a part of the rotation shaft inserted therein. The connecting link has a base end rotatably attached to the other of the pair of constituent members, and a locking projection for locking the side surface of the rotating shaft. The locking protrusion is provided at a position that engages with the rotating shaft through the shaft exposing portion when in the folded state. In the second invention as described above, as described above, even if the length adjusting mechanism is provided, the number of parts is not large, the structure of the entire band is simple, the manufacturing cost of the timepiece can be reduced, and The length can be easily adjusted without using a dedicated tool, and even if the body part becomes slightly thicker due to swelling etc., the length adjustment makes the watch feel comfortable at all times.
