JPH083289Y2 - Adjusting structure of watch band - Google Patents

Description

[Detailed Description of the Invention] <Industrial field of application> The present invention relates to the structure of the adjusting portion of a watch band, more specifically, the adjuster of a watch band in which the unit piece can be easily removed and adjusted to adjust the watch band length. It is related to the partial structure.

<Prior Art> As a conventional example of this type, there is JP-B-48-4916. In this publication, when a large number of band bodies having a pair of mounting shafts are connected to each other with a connecting fitting while keeping a slight distance from each other, the connecting fitting has a curved substrate and one edge of this board. And a locking plate that is freely rotatably attached to the plate, and the locking plate is attached to the free end of the locking plate that is elastically locked to the other edge of the substrate. The tongue pieces projecting inwardly of the base plate close to the base are provided on both side edges, and the locking plate connects the band body to the back side of the band and the base plate to the front side of the band. It describes the watch band.

<Problems to be Solved by the Invention> However, in the above-mentioned publication, not only is it difficult for the locking portion end 12 of the locking plate 10 to form a step and to be seen from the upper surface,
Since they are merely overlapped and locked, there is a problem that the locking is released due to an impact or the like, and the connecting metal fittings fall out of the band main body and do not perform the connecting function.

<Means for Solving the Problems> According to the present invention, two side pieces and two connecting pins extending in parallel with each other at a distance between the side pieces and one end of one of the connecting pins are fitted. , A unit piece having a connecting piece projecting the other end in the connecting direction, the connecting piece is divided into an upper lid and a lower plate, and the connecting pin is provided inside one end of the connecting direction of the upper lid and the lower plate. An engaging holding cylinder for inserting and holding one of them is provided, and a downward curved edge that rotates and opens and closes at the other end in the connecting direction of the upper lid and the lower plate and a semicircular retaining portion that contacts the inner surface of the downward curved edge, respectively. Provided with an engaging concave and convex portion between the downward curved edge and the semicircular holding portion, and providing a hole for releasing the engaging of the engaging concave and convex portion in the middle part of the lower plate. , The other one of the connecting pins of the adjacent unit pieces is held by the semicircular holding portion so as to be freely drawn out. Configure
It is intended to solve such a problem.

<Operation> The present invention is a unit in which a thin rod-shaped tool such as an awl is inserted through a small hole provided in the middle of the lower plate and the upper lid is pushed to unlock the uneven portions for latching and the upper lid is rotated to open and close. One of the connecting pins of the piece is removed, and the unit piece between the removed connecting pins is removed and reconnected to adjust the band length to fit around the wrist.

<Example> An example will be described below with reference to the drawings.

The connecting piece 10 is divided into an upper lid 3 and a lower plate 5, downward bending edges 1a and 1b are provided at both ends of the upper lid 3 in the connecting direction, and a holding tube 2 is attached to an intermediate portion of one downward bending edge 1a. Holding cylinders 2a, 2 which mesh with the holding cylinder 2 on both sides of one end of the plate 5 in the connecting direction
b is provided, and a semicircular holding portion 4 that contacts the inner surface of the downward curved edge 1b of the upper lid 3 is formed at the other end of the lower plate 5 in the connecting direction. 6
Reference numerals a and 6b are concave and convex portions for hooking, which are provided so as to face the joint surface of the downward curved edge 1b and the semicircular holding portion 4, and 7 is a thin portion for inserting a pressing tool provided in the middle of the lower plate 5. It is a hole.

The connecting piece 10 thus formed is engaged with the holding cylinder 2 of the upper lid 3 with the holding cylinders 2a and 2b of the lower plate 5, the connecting pin 8a is inserted and held, and a space is provided outside the downward curved edge 1a. Side pieces 9a, 9b are driven at both ends together with parallel connecting pins 8b to assemble and form a unit piece 11 in which a downward curved edge 1b and a semicircular holding portion 4 are projected in the connecting direction.

The unit pieces 11 are pivotally opened between the downward curved edge 1b of the connecting piece 10 and the semicircular holding portion 4 based on the connecting pin 8a, and the adjacent unit pieces 11 are connected by the semicircular holding portion 4. The watch band of a predetermined length is knitted in such a manner that the holding pin 8b is held, the upper lid 3 is redeposited, and the engaging concave-convex portions 6a and 6b are engaged and locked to each other.

If the length of the band is long between the wearer's wrist and the wearer's wrist, insert a thin rod-shaped tool (not shown) such as an awl through the hole 7 provided in the middle of the lower plate 5 of the connecting piece 10. Then, the upper lid 3 is unfolded and rotated to pull out the connecting pin 8b from the semi-circular holding portion 4, and then one to several unit pieces 11 are pulled out, and then the band length is adjusted so that they are re-joined to fit. To do.

<Effects of the Invention> As described above, the present invention divides the connecting piece, which is fitted as a unit piece so as to partially protrude in the middle between the side pieces, into the upper lid and the lower plate, and has a holding portion that is meshed at one end. Since the projecting side of the connecting piece is pivotally opened and closed based on the connecting pin that holds and inserts through, the semi-circular holding portion of the lower plate provided on the pivotal opening and closing side of the adjacent unit piece The effect that the connecting pin can be easily held or removed, and the length of the watch band can be adjusted extremely easily by removing and reconnecting the unit pieces.

Since the downward curved edges that cover the both ends of the lower plate are provided on both sides in the connecting direction of the upper lid, the connecting piece has an effect of being seen as a solid body from the upper surface and giving an aesthetic appearance and a high-class feeling.

Since a concave and convex portion for locking is provided between the downward curved edge of the protruding side of the upper lid and the semicircular holding portion, the meshing is stopped.
Even if the watch band is pulled or an impact is applied, the lid is unintentionally opened to prevent the connecting pin from being pulled out.

Since the small hole is provided in the middle of the lower plate, the effect that the tool can be inserted through the small hole and the upper lid can be pushed to unlock the uneven portion for latching and the upper lid can be pivotally opened. Cause
