Abstract

(57) [Summary] [Purpose] To obtain a connection structure that can be easily connected or disconnected with one touch. [Structure] The sandwiching pieces 34 face each other in an elastically deformable cantilever state, and when the connecting piece 20 is fitted between them, the sandwiching pieces 34 are gradually expanded by the projections 22 and the vertical surfaces 22B of the projections 22 are locked. When reaching the hole 36, the protrusion 22 is engaged with the locking hole 3
It is taken into 6 and elastically returns to the original state. As a result, the vertical surface 22B of the projection 22 is locked in the locking hole 36, and the withdrawal of the connecting piece 20 is prevented. Further, when the connecting piece 20 is pushed into the sandwiching piece 34, the sandwiching piece 34 will be projected.
It is pushed out by 2. Here, since the projection 22 is not locked in the locking hole 36, when the connecting piece 20 is slid in the direction orthogonal to the pushing direction, the connected state of the connecting piece 20 and the sandwiching piece 34 is released.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connecting structure applied to a buckle of a watch band.

[0002]

[Prior art]

 As a means for detachably connecting the two members, there are buckles 84 and 86 for stopping the band 82 of the wristwatch 80 as shown in FIGS. 8 and 9 (see JP-A-63-63406).

In the buckle 82 shown in FIG. 8, a locking piece 90 elastically deformable provided on the frame 88 is elastically deformed in a direction to be pushed into the frame 88 and is inserted into the opening 94 of the tubular body 92. Then, when it reaches the locking window 96, it elastically returns and the claw portion 90A is locked to the edge portion 96A of the locking window 96.

Further, in the buckle 86 of FIG. 9, a pair of leg members 100 provided at both ends of the locking body 98 are elastically deformed in a direction in which they approach each other and are inserted into the opening 104 of the tubular body 102. When it is inserted and elastically returns to the locking window 106, the claw portion 100A is locked to the edge portion 106A of the locking window 106.

In such buckles 84 and 86, when releasing the connected state, either the fingertips press the locking piece 90 (see FIG. 8) or the side surface 100B of the leg member 100 is sandwiched (see FIG. 9). It is necessary to release the locking state and pull out the locking piece 90 or the leg material 100.

That is, in the conventional buckle, since the connecting direction and the connecting releasing direction are both on the same straight line, it is always necessary to operate the engaging portion with a fingertip to release it.

Therefore, it is not easy to attach and detach the buckle when it is difficult to operate the engaging portion with fingertips, such as when using thick gloves.

[Action]

 In the connection structure according to claim 1, the plate-shaped connection piece attached to the first member is inserted into the sandwiching piece attached to the second member, and the first member and the second member are connected. .

The sandwiching pieces face each other in an elastically deformable cantilever state, and when the connecting piece is inserted between them, the sandwiching piece is gradually expanded by the protrusions standing from the flat surface of the connecting piece, and When the vertical surface reaches the locking hole of the sandwiching piece, the projection is taken into the locking hole and elastically returns to the original state. As a result, the vertical surface of the protrusion is locked in the locking hole of the holding piece, and the connecting piece is prevented from being pulled out from the holding piece.

Next, when releasing the connected state, when the connecting piece is further pushed into the holding piece, the projection is guided out by the inclined surface in the pushing direction from the locking hole, and the holding piece is expanded by the protrusion. To be Here, the protrusion is not locked in the locking hole, and the connecting piece is simply held by the holding piece. Therefore, when the connecting piece is slid in the direction orthogonal to the pushing direction, the connected state between the connecting piece and the sandwiching piece is released.

Further, in the connecting structure according to the second aspect, when the connecting piece is inserted between the holding pieces, the flat surface portion of the connecting piece and the projection slide to gradually expand the holding piece. Next, when the projection reaches the vertical surface of the locking groove, the projection enters the locking groove, and the sandwiching piece elastically returns to the original state. As a result, the protrusion locks the vertical surface of the locking groove and prevents the connecting piece from being pulled out from the holding piece.

Next, when releasing the connected state, when the connecting piece is further pushed into the sandwiching piece, the projection is guided by the inclined surface and comes out from the locking groove in the direction opposite to the pushing direction, and the sandwiching piece is pushed by the projection. Can be expanded. Here, the projection is not locked in the locking groove, and the connecting piece is simply sandwiched between the projection and the sandwiching piece. Therefore, if the connecting piece is slid in the direction orthogonal to the pushing direction, the connected state between the connecting piece and the sandwiching piece is released.

【Example】

 FIG. 1 shows a buckle of a watch band to which the connecting structure according to the first embodiment is applied.

The buckle 10 includes a holding member 14 attached to the timepiece band 12 side and a connecting member 18 attached to the timepiece 16 side and inserted into the holding member 14.

The connecting member 18 is provided with a plate-like connecting piece 20 having rounded corners. At the center of the upper surface of the connecting piece 20, two protrusions 22 are provided upright in the width direction. One side of the projection 22 forms a vertical surface 22B, and the other side forms an inclined surface 22A that is inclined toward the tip of the connecting piece 20.

On the other hand, one end of the connecting piece 20 is a thick connecting portion 24, and a step portion 24 A is formed between the connecting piece 20 and the connecting piece 20. Further, the end portion of the connecting portion 24 is cut into a width that can be inserted into the bracket 26 of the timepiece 16, and the axial hole 28 is penetrated in the longitudinal direction. The spring rod 30 is inserted into the shaft hole 28 so that the bracket 26 of the timepiece 12 and the connecting member 18 are connected to each other.

The holding member 14 into which the connecting member 18 is inserted has a shape like a sheet of material bent in a U shape, and has a cantilevered holding piece 34 having the U-shaped bent portion 32 as a fixed point. Have The sandwiching pieces 34 can be elastically deformed in the direction away from each other, and a rectangular engaging hole 36 is formed on the free end side of one sandwiching piece 34. The locking hole 36 is sized to accommodate the projection 22 provided on the connecting piece 20. Further, the free end portion of the sandwiching piece 34 is formed with a taper portion 34A that inclines inward, and when the connecting piece 20 is inserted between the sandwiching pieces 34, the stepped portion 24A of the connecting member 18 is contacted. It comes into contact (see Fig. 2).

As shown in FIGS. 1 and 5, a guide projection 38 and a detent projection 40 are provided on the rear surface side of the edge of the locking hole 36. The guide protrusion 38 is a triangular pyramid that rises and slopes toward the U-shaped bent portion 32, and is positioned between the two protrusions 22 when the connecting piece 20 is inserted between the sandwiching pieces 34. The projection 22 is guided into the locking hole 36. Similarly, the detent projection 40 also has an inclined surface that swells and inclines toward the U-shaped bent portion 32, and a vertical surface 40A that stands upright, and when the connecting piece 20 is pushed into the sandwiching piece 34, the vertical direction. The surface 40A locks the vertical surface 22B of the protrusion 22 so that the connecting piece 20 is not pushed back by the elastic force of the sandwiching piece 34 (see FIG. 5).

It should be noted that a pair of support pieces 41 project from both ends in the width direction at the ends of the holding member 14. The spring rod 30 is inserted into the mounting hole 42 formed in the support piece 41 so that the timepiece band 12 and the holding member 14 are connected.

Next, a method of handling the buckle 10 will be described. As shown in FIGS. 2 and 4, when the connecting piece 20 is inserted between the sandwiching pieces 34, the inclined surface 22A of the projection 22 is guided by the tapered portion 34A formed at the tip of the sandwiching piece 34, and the sandwiching piece 34 is formed. To spread. At this time, the guide protrusion 38 is positioned between the two protrusions 22, and guides the protrusion 22 into the locking hole 36 while correcting the positional deviation in the width direction. When the projection 22 reaches the inside of the locking hole 36, the sandwiching piece 34 elastically returns to the original state and the vertical surface 22B of the projection 22 is locked to the edge portion of the locking hole 36. As a result, the connection state between the connecting piece 20 and the sandwiching piece 34 is maintained against the pulling force in the direction of arrow A.

Next, as shown in FIGS. 3 and 5, when releasing the connection state between the connecting piece 20 and the sandwiching piece 34, the connecting piece 20 is further connected to the U-shaped bent portion 32 of the sandwiching piece 34. Push it in (the direction opposite to arrow A). As a result, the protrusion 22 moves along the inclined surface of the detent protrusion 40, and pushes and extends the holding piece 34. Further, at this time, since the step portion 24A of the connecting portion 24 is guided by the taper portion 34A, the connecting piece 20 can be easily pushed.

Next, when the protrusion 22 passes through the inclined surface of the detent protrusion 40, as shown in FIG. 5, the sandwiching piece 34 is expanded by only the protrusion 22 and a part of the step portion 24A, and the connecting member 18 is expanded. The other parts of are not in contact with the sandwiching piece 34. Here, as shown in FIG. 3, when the connecting member 18 is slid in a direction orthogonal to the pushing direction, the connecting piece 20 is detached from the sandwiching piece 34.

As described above, in the buckle 10 described above, the engagement state between the protrusion 22 and the engagement hole 36 is released only by the pushing operation of the connecting member 18, and the connecting piece 20 is slid in the direction orthogonal to the pushing direction. It is easy to handle because it only needs to be done. Although the projection 22 and the locking hole 36 are provided on only one surface in the above-described embodiment, they may be provided on both surfaces in a buckle that requires a locking force.

Further, in the above-described embodiment, the guide projection 38 guides the connecting piece 20 between the sandwiching pieces 34, but the connecting piece 20 and the connecting piece 20 which are in a non-contact state when pushed (see FIG. 5) are sandwiched. By separately forming a guide mechanism at the portion with the piece 34, the protrusion 22 can be accurately guided into the locking hole 36. Furthermore, the connecting structure according to the present embodiment is not limited to being applied to the buckle of a watch band, but can be applied to, for example, a connecting portion between plate materials, and the use is not limited.

Next, a second embodiment will be described. As shown in FIGS. 6 and 7, in the buckle 49 according to the second embodiment, the protrusion 54 is provided on the surface of the holding member 50 facing the holding piece 34. On the other hand, on the upper surface of the connecting piece 20 of the connecting member 52, a locking groove 56 having a vertical surface 56A on the insertion direction side and an inclined surface 56B on the opposite side is recessed. Further, on the upper surface of the connecting piece 20, a guide groove 58 is formed apart from the locking groove 56 in the width direction of the connecting piece 20.

When the connecting piece 20 is inserted between the sandwiching pieces 34, the sandwiching piece 34 is expanded while the projection 54 and the upper surface of the connecting piece 20 slide. Next, when the vertical surface 56A of the locking groove 56 corresponds to the projection 54, the projection 54 enters the locking groove 56, and the sandwiching piece 34 elastically returns to the original state. As a result, the vertical surface 56A of the locking groove 56 is locked to the protrusion 54, and the connected state of the connecting piece 20 and the sandwiching piece 34 is maintained against the pulling force in the direction of arrow A.

Next, when releasing the connected state between the connecting piece 20 and the sandwiching piece 34, the connecting piece 20 is further pushed toward the U-shaped bent portion 32 of the sandwiching piece 34 (the direction opposite to the arrow A). As a result, the protrusion 54 and the inclined surface 56B of the locking groove 56 slide, and the holding piece 34 is expanded.

Next, when the inclined surface 56B passes through the projection 54, the guide groove 58 formed across the width direction of the connecting piece 20 and the projection 54 are engaged with each other, and the holding piece 34 is expanded. Here, as shown in FIG. 3, when the connecting member 18 is slid in the direction orthogonal to the pushing direction, the connecting piece 20 is detached from the sandwiching piece 34.

As described above, in the above-described buckle 49, the sliding movement of the connecting member 18 is guided by the guide groove 58, so that the detaching operation can be smoothly performed. Further, the shapes of the projection, the hole, the sandwiching piece, etc. are not limited as long as the locking state of the projection and the hole for locking the projection is released by the pushing operation of the connecting member 18.
