Description

  The present invention relates to a watch band type clasp that opens and closes both ends connected to the watch band.

2. Description of the Related Art Conventionally, a watch band buckle has a kannon type lock structure in which both ends connected to the watch band are opened and closed (Patent Document 1, etc.).
On the other hand, watch bands include those made by cutting and processing a band-shaped net into the shape of a band, and what is called a “mesh band” by assembling coiled parts and connecting them with pins (Patent Literature). 2 etc.).

  Conventionally, however, the Kannon type Nakadome is often used for metal bands such as muk bands and plate-wound bands. However, it was rarely used in the type of inserting a stick bar provided on the band on the side of the beautiful tablet. In addition, the Kannon type Nakadome used for mesh bands has never existed.

  Accordingly, the present invention is intended to provide a novel Kannon type middle ring used for a “beautiful tablet type” watch band, particularly a mesh band.

In order to achieve the above object, a first device is a watch band type clasp that opens and closes both ends connected to a watch band, and a hook is attached to an end of one of the opening and closing plates. An attachment member is provided for connecting the sword tip band having a locking hole for insertion through a length adjustable and detachable, and the attachment member is rotatably attached to the end of the opening and closing plate and is associated with the sword tip band. A watch band comprising: a lower plate provided with a locking projection for insertion through a stop hole; and an upper box that is pivotably attached to the upper side of the lower plate and controls the attachment and detachment of the sword tip band. It is a kannon type Nakadome.
The second device is a kannon type clasp for the watch band characterized in that the mounting member includes a lock mechanism for fixing the upper box to the lower plate and maintaining the wearing state of the sword band.
A third idea is a kannon type middle ring for the watch band, wherein the watch band including the sword tip band is a mesh band.

The above device has the following effects.
(1) An attachment member is provided at the end of one opening / closing plate that opens and closes the kannon-type fastener, and the attachment member is provided with a lower plate and an upper box, so that the sword tip band can be freely adjusted in length and detachable. This makes it possible to use a beautiful lock-type watch band for the Kannon-style Nakadome.
(2) By providing the lower plate and the upper box constituting the attachment member with a lock mechanism, the sword tip band can be reliably fixed to the attachment member.
(3) If it is a mesh band provided with a latching hole, it is possible to use a kannon type string.

An embodiment of a watch band kannon type middle ring according to the present invention will be described with reference to the drawings.
FIG. 1 is an exploded view of a watch band kannon type middle ring.
The watch band kannon type clasp 10 shown in FIG. 1 includes an attachment member 30 at an end portion 21 of one opening / closing plate 20 that opens and closes. A mesh band (sword tip band) attached to the 6 o'clock side of the watch band is attached to the opening / closing plate 20 via the attachment member 30, and attached to the other opening / closing plate 25 via the joint piece 26 to the 12 o'clock side. A mesh band is attached (the mesh band is not shown). Both the opening and closing plates 20 and 25 can be opened with one touch by push buttons 12 and 12 provided on the middle terminal body 11.

The attachment member 30 includes a lower plate 40 and an upper box 50. The lower plate 40 is rotatably attached to the end portion 21 of the opening / closing plate 20 via a connecting pin (not shown), and is provided with a locking protrusion 41 for being inserted into the locking hole of the blade tip band. Yes.
The upper box 50 has a substantially U-shaped cross section and is pivotably attached to the upper side of the lower plate 40 via the connecting pin to control the attachment / detachment of the sword tip band. That is, when wearing the sword band, the upper box 50 is closed to the lower plate 40 side. When the sword band is detached, the upper box 50 is released from the lower plate 40 and opened.

  The attachment member 30 includes a lock mechanism 31 for securely fixing the sword band. The lock mechanism 31 maintains a state in which the upper box 50 is closed to the lower plate 40 side, and is formed on the upper box 50 and convex portions 42 and 42 formed at portions contacting the upper box 50 of the lower plate 40. It is comprised by fitting of the recessed parts 52 and 52 which were made.

FIG. 2 is an assembly drawing of the watch band type clasp for the watch band.
2 shows a state in which the lower plate 40 and the upper box 50 are locked by the lock mechanism 31 of the mounting member 30 while the opening and closing plates 20 and 25 are closed. 2A is a perspective view showing a state in which the attachment member 30 is in front, and FIG. 2B is a perspective view showing a state in which the attachment member 30 is on the other side.

  In the present invention, a kannon type middle ring can be used for a mesh band. Furthermore, the present invention can be widely used not only for mesh bands but also for beautiful lock-type watch bands.
