Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a fastener that is applied to a watch band.

"Prior Art and its Problems" There are various forms of watch band fasteners, such as an intermediate fastening method, a locking method, and a tri-fold method, each of which has the following characteristics. In other words, it is relatively easy to adjust the overall length of the band with intermediate fastening type and locking type fasteners, and in particular, locking type fasteners can be worn on the wrist without prior adjustment. Although it has the advantage of being able to set the locking position arbitrarily, it has the disadvantage that when the lock is released, the stopper separates into two parts, making it easy for the band to fall off the wrist. This type of fastener retains the entire band in a loop shape even when the lock is released, which has the advantage of preventing it from falling off the wrist, but has the disadvantage that it is difficult to adjust the length. be.

As a three-fold fastener that eliminates the above drawbacks, a slide piece is provided that has a plurality of first fixing holes, a plurality of second fixing holes, and one elongated hole on the inside of the bottom plate that contacts the wrist. It is attached movably in the length direction of the bottom plate, and the second protrusion provided on the bottom plate is inserted into the elongated hole to prevent the slide piece from being pulled out from the bottom plate, and the first protrusion provided on the bottom plate is inserted into the long hole. Fix the slide piece to the bottom plate at an arbitrary length by fitting it into any one first fixing hole, and
It is known that the top plate is foldably connected to one end of the bottom plate by a hinge, and an elastic snap of the top plate is fitted into a second fixing hole to maintain the folded state of the top plate with respect to the bottom plate. -5940 Publication).

However, the above-mentioned three-fold type fastener has a plurality of first fixing holes and a plurality of second fixing holes in the slide piece.
and one long hole must be formed,
There is a problem that the length adjustment range inevitably becomes short. Moreover, the plurality of first and second fixing holes,
Since the slide piece with the elongated hole is provided inside the bottom plate and comes into direct contact with the skin, there is also the problem that it does not feel good against the skin. In addition, since the first protrusion is attached to and removed from the first fixing hole by bending the slide piece, it is even more difficult to adjust the length if the slide piece is provided on the outer surface of the bottom plate to improve the texture. Become.

The object of the present invention is to provide a tri-fold type stopper for a watch band that is easy to adjust in length, has a wide range of length adjustment, and is comfortable to the touch.

``Means for Solving the Problems'' In order to achieve the above object, the present invention provides that the other end of the bottom plate, whose free end is connected to one watch band piece, has a top plate superimposed on the outer surface of the bottom plate. A watch band stopper in which one end of a plate is foldably connected at a hinge part, and an upper box connected to the other watch band piece is rotatably connected to the other end of the upper plate at another hinge part. , a slide piece having, on the outer surface of the bottom plate, a connecting part for one watch band piece at one end, a stopper at the other end, and a plurality of engaging parts formed in the center part at predetermined intervals in the length direction; The connecting portion is disposed on the free end side of the bottom plate, and is supported by protruding pieces formed along the bottom plate on both sides of the bottom plate so as to be movable in the length direction of the bottom plate,
At the free end of the bottom plate, a rounded protrusion is engaged with the engaging part to lock the slide piece to the bottom plate;
In addition, an elastic locking piece is attached to the end of the upper box on the upper box side of the upper plate to abut the stopper of the sliding piece and prevent the sliding piece from being pulled out from the bottom plate, and the elastic locking piece is attached to the upper box side end of the upper plate and locks on the protruding piece to prevent the sliding piece from being pulled out from the bottom plate. The structure includes a locking pawl that maintains the folded state of the plate, and a stopper pawl that engages with the engaging portion of the slide piece to fix the slide piece to the top plate when the top plate is folded relative to the bottom plate.

"Embodiment" Hereinafter, one embodiment of the watch band stopper according to the present invention will be described based on the drawings.

In the figure, reference numeral 1 denotes a bottom plate; reference numeral 2 denotes an upper plate rotatably connected to one end of the bottom plate 1 by a hinge part 3;
Reference numeral 4 is rotatably connected to the free end of the top plate 2 by a hinge part 5, and also connects the bottom plate 1 and the top plate 2.
When the two are folded together, an upper box that covers the upper plate 2 and is locked to the bottom plate 1 comes out.

The former sole plate 1 is made of a metal plate curved to fit the wrist, and both sides are raised vertically, and a protruding piece 1b is provided inward at a part of each raised part 1a. These startup parts 1
A slide piece 6, which can be freely pulled out in the length direction of the band, is inserted from the free end side of the bottom plate 1 into the space surrounded by the protruding piece 1b. A lock piece 7 is provided at the free end of the bottom plate 1 to restrict movement of the slide piece 6.
is provided.

The slide piece 6 as a whole is formed to have a width slightly larger than the opposing spacing between the protruding pieces 1b of the bottom plate 1, and has protruding parts 6a facing outward in the width direction at the insertion side end. In addition, both sides are vertically raised, and the center part in the width direction is also formed to protrude in the thickness direction, and a pair of grooves 8 along the length direction of the band are formed in parallel between them. Furthermore, a stopper 6b that protrudes downward in the thickness direction is provided at the tip of the central portion. And one watch band piece A ₁ on the end of the drawer side
A connecting portion 9 for attaching a connecting piece is provided, and a plurality of holes 10 are arranged at a constant pitch in the length direction of the band in the protruding central portion.

In addition, the lock piece 7 is inserted with its tip (the right end in FIGS. 1 and 2) between the bottom plate 1 and the slide piece 6, and the slide piece 6 is raised above the surface of the bottom plate 1. It is fixed to the free end of the bottom plate 1 in contact with the lower surface. The base end portion (the left end portion in FIGS. 1 and 2) of the lock piece 7 is divided into two parts, protrudes from both sides of the slide piece 6, and pivotally supports the pin 11. The pin 11 extends above the slide piece 6. Further, a protrusion 7a that fits into the hole 10 of the slide piece 6 is provided on the surface of the tip of the lock piece, and the elasticity of the tip urges the slide piece 6 in a direction to press it from below. are doing. The protruding portion 7a is formed in the hole 1 when the slide piece 6 is moved in the longitudinal direction shown by the arrow A in the following figures by applying a slight force from the state shown by the solid line in FIGS. 1 and 2.
In order to easily deviate from zero, it is formed into a slightly rounded state by drawing in a press or the like.

On the other hand, the top plate 2 is curved to match the bottom plate 1, and most of the top plate 2 except for the tip is formed on the bottom plate 1.
The width dimension is set to be slightly smaller than the facing interval of the protruding pieces 1b, and when both sides thereof are raised and folded on the bottom plate 1, the raised parts 2a will fit into the grooves 8 of the slide piece 6. It is becoming more and more engaged. Furthermore, the free end portion includes a pair of locking claws 12 that are locked to the tips of both the protruding pieces 1b when folded onto the bottom plate 1, and a hole 10 of the slide piece 6.
A stopper pawl 13 inserted into the housing is integrally provided.

The upper box 4 is formed by bending a metal plate into a U-shape as a whole, and includes a folded bottom plate 1,
It is designed to cover the outside of the top plate 2, and its free end is provided with a connecting part 14 for attaching the connecting piece of the other watch band _A2 .

Note that the pin 1 provided on the lock piece 7
1 are rotatably provided at both ends of the bottom plate 1, upper plate 2, and upper box 4 for holding down the recess 4a of the upper box 4 to maintain the folded state.

The stop metal fitting constructed in this way can be assembled by rotating the holding metal fitting 15 as shown by the arrow B from the locked state shown in FIG. 4, and then turning the upper box 4 as shown by the arrow C. Releasing the locked state,
As shown in Figure 1, the bottom plate 1, the top plate 2 and the top box 4
can be in an expanded state. In the state shown in FIG. 1, when the slide piece 6 is pulled in the longitudinal direction of the band shown by arrow A, the protrusion 7a of the lock piece 7 fitted into the hole 10 of the slide piece 6 is removed. is pressed, and the lock piece is elastically deformed downward as shown by arrow D, thereby releasing the fitted state with hole 10 and moving slide piece 6 as shown by chain lines in FIGS. 1 and 2. It can be pulled out from the bottom plate 1. Therefore, when adjusting the overall length of the band, such as when wearing it on the wrist, open the bottom plate 1, top plate 2, and top box 4 as shown in FIG. This can be easily done by pulling out the watch and changing the engagement position between the hole 10 and the protrusion 7a of the lock piece 7, and is suitable for cases where the length needs to be adjusted frequently, such as in a diver watch. It is. Note that the stopper 6b at the tip of the slide piece 6 is engaged with the tip of the lock piece 7 to prevent the slide piece 6 from coming off when the slide piece 6 is pulled out from the bottom plate 1 to the vicinity of the tip. I can do it.

On the other hand, when worn on the wrist, both locking claws 12 of the top plate 2 are locked to the tips of both protruding pieces 1b of the bottom plate 1, as shown in FIGS. 4 and 5.
Since the stopper claw 13 provided on the upper plate 2 is inserted into one of the holes 10 of the slide piece 6, it prevents the slide piece 6 from moving when tension is applied to the band.
The state of attachment to the wrist can be maintained reliably.

In addition, since it basically has a so-called three-fold structure, when the bottom plate 1 and the upper box 4 are released from the locking state, the entire band is maintained in a loop shape.
Of course, it is possible to prevent it from falling off the wrist.

In one embodiment, the means for engaging the slide piece 6 and the lock piece 7 is provided by providing a plurality of holes 10 at a constant pitch in the slide piece as engaging portions.
However, the structure is such that the protrusion 7a of the lock piece 7 is fitted into the lock piece 7. The present invention is not limited to the structure of this embodiment, and a structure may be adopted in which the slide piece is made of a corrugated plate and a part of the lock piece is engaged with the recessed part of the slide piece.

"Effects of the Invention" As explained above, the watch band fastener according to the present invention has the above-mentioned structure, and therefore has the following effects.

Since one watch band piece is connected to the bottom plate via a movably provided slide piece, the length of the entire band can be adjusted.

Since the slide piece is held by a protruding piece on the outer surface of the bottom plate and does not directly touch the wrist, the feel will not be impaired.

Since the inner end of the slide piece is provided with a stopper that comes into contact with the lock piece and prevents the slide piece from being pulled out, it is possible to increase the movement width of the slide piece, that is, the length adjustment width. .

The structure is such that a rounded protrusion formed at the tip of the elastic locking piece engages with an engaging part of the slide piece to temporarily fix the slide piece to the bottom plate, and the protrusion engages with the engaging part. can be removed by simply applying a little strong force in the longitudinal direction of the slide piece, making length adjustment easy.

The protruding piece that holds the slide piece on the bottom plate works to lock the locking pawl, and the elastic lock piece works together with the stopper to prevent the slide piece from being pulled out, so the overall structure is simplified accordingly. can do.
