However, in the past, in order to attach and detach the frame, it has been necessary for a store clerk or other specialist who is familiar with the handling of the band or the like to use a dedicated tool. It was difficult to do.
For this reason, if the belt length cannot be adjusted by the store salesperson, for example, when it is necessary to adjust the size after purchase, or when purchasing via mail order, etc., the user can adjust the band length by himself / herself. It was difficult to carry out the work, and it was very inconvenient because it had to be brought to a store with specialists.

In this respect, for example, in Patent Document 1, a small rod-like body is inserted into the frame body, and a connection pin (connection protrusion) that connects the frame bodies protrudes from the adjacent frame body. There has been proposed a configuration in which the connecting pin (connecting protrusion) is moved inward, thereby releasing the connecting state by the connecting pin (connecting protrusion) in the adjacent piece.
According to this, since the frame can be attached and detached with one push, even a normal user can attach and detach the frame relatively easily, and the length of the band can be easily adjusted.

For example, when the insertion hole 234a is formed in the surface portion 231 of the outer frame 23, the insertion hole 241a is also formed at a position corresponding to this. In this embodiment, the insertion hole 234a of the outer frame 23 and the insertion hole 241a of the inner frame 24 constitute an insertion hole into which the shaft portion 12 of the frame attaching / detaching jig 1 is inserted.
Further, the protruding portion 242 is formed with a hollow cylindrical portion 242a along the width direction of the frame body 2 by bending the end portion of the plate member. The cylindrical portion 242a has an inner diameter larger than the diameters of the connecting projections 253 and 263 of the moving members (the first moving member 25 and the second moving member 26) described later. The connecting projections 253 and 263 of the first moving member 25 and the second moving member 26 are accommodated in the cylindrical portion 242a of the adjacent frame body 2 so as to be able to appear and retract.

The first moving member 25 and the second moving member 26, which are a pair of moving members, are disposed inside the inner frame 24 so that the inner end faces face each other.
The first moving member 25 and the second moving member 26 are respectively plate-shaped moving main body portions 251 and 261, protruding portions 252 and 262 protruding to one end side of the moving main body portions 251 and 261, and the protruding portions. And connecting projections 253 and 263 provided at end portions of 252 and 262.
The movable body portions 251 and 261 are formed with inclined surfaces 251 a and 261 a that are inclined inwardly from the surface facing the insertion holes 234 a and 241 a to the opposite surface on the inner end surfaces thereof. The movable main body portions 251 and 261 are formed with laterally long grooves 251b and 261b that open outward. Coil springs 27a and 27b are disposed in the horizontally long grooves 251b and 261b.
The coil springs 27a and 27b are urging members that urge the first moving member 25 and the second moving member 26 in the direction in which the connecting protrusions 253 and 263 are maintained in the inserted state. In the present embodiment, one end sides of the coil springs 27 a and 27 b are in contact with the back of the horizontally long grooves 251 b and 261 b, and the other end side is in contact with the inner wall of the external frame body 23.
The coil springs 27a and 27b protrude from the horizontally long grooves 251b and 261b in the extended state to press the first moving member 25 and the second moving member 26 inward (see FIG. 6), and are substantially horizontally long grooves 251b in the compressed state. , 261b (see FIG. 9).
The urging member is not limited to the coil springs 27a and 27b, and may be composed of an elastic body such as rubber.
Further, the connecting protrusions 253 and 263 are provided so as to protrude toward the inner side opposite to the outer side where the horizontally long grooves 251b and 261b open. The connecting projections 253 and 263 are inserted into the adjacent pieces 2 to lock the pieces.

  The first moving member 25 and the second moving member 26 are arranged inside the moving main body portions 251 and 261 so that the coil springs 27a and 27b are arranged in the horizontally long grooves 251b and 261b and the connecting protrusions 253 and 263 are opposed to each other. Are arranged inside the inner frame 24 with their end faces facing each other.

Next, the action of the frame attaching / detaching jig 1 in this embodiment will be described with reference to FIGS. 7 to 9.
In the state in which the frame body 2 of the present embodiment is not mounted, as shown in FIG. 6, the first moving member 25 and the second moving member 26 are moved inward by the coil springs 27a and 27b. The inner end surfaces of the first moving member 25 and the second moving member 26 are in contact with each other by receiving the biasing force, and the connection protrusions 253 and 263 protrude into the recess 22 of the frame body 2. It has become a state.
Thereby, when the frame body 2 is adjacent to the other frame body 2, the connection protrusions 253 and 263 are adjacent to each other inside the adjacent frame body 2 by the urging force of the coil springs 27 a and 27 b (in this embodiment, the frame body 2). It is maintained in the inserted state inserted into the cylindrical portion 242a in the convex portion 21 of the body 2.

  When the frame body 2 is removed from the band 10, as shown in FIGS. 7 and 8, the base portion 11 of the frame body attaching / detaching jig 1 is superposed on the back surface side of the frame body 2, so that a transparent or translucent base portion is formed. The shaft portion 12 is arranged at a position where the shaft portion 12 can be inserted into the insertion holes 234 a and 241 a of the frame body 2 while the user visually confirms the position through 11. At this time, since the hanging portions 13 are respectively arranged outside the both side portions of the frame body 2, positioning of the frame body attaching / detaching jig 1 is facilitated, and a plurality of the frame bodies 2 are continuously removed from the band 10. At this time, since the hanging portion 13 serves as a guide, the piece attaching / detaching jig 1 can be smoothly moved to the next piece 2 along the connecting direction of the band 10.

To move.
Accordingly, the moving members (the first moving member 25 and the second moving member 26) move against the urging force of the coil springs 27a and 27b, which are urging members. That is, in this embodiment, the frame body 2 moves to the opposite side in the width direction (the left and right outer sides in FIGS. 6 and 9).
As a result, the connection protrusions 253 and 263 of the first moving member 25 and the second moving member 26 are accommodated in the inner frame 24. When the piece 2 is connected to another adjacent piece 2, the insertion state of the connection protrusions 253 and 263 is thereby released, and the piece 2 can be removed from the other piece 2. Become.

  Similarly, when the frame body 2 is attached to another frame body 2, the frame body attaching / detaching jig 1 is similarly arranged at a predetermined position on the back side of the frame body 2, and the first moving member 25 and the second movement After the connecting projections 253 and 263 of the member 26 are accommodated in the inner frame 24, the recess 22 of the frame 2 in a state in which the connecting projections 253 and 263 are accommodated and the mounting target frame 2 The convex part 21 is fitted. Then, by removing the frame attaching / detaching jig 1 from the frame 2, the connecting protrusions 253 and 263 of the first moving member 25 and the second moving member 26 protrude by the urging force of the coil springs 27 a and 27 b and are attached. The inserted state inserted into the cylindrical portion 242a in the convex portion 21 of the previous piece 2 is maintained, and the pieces 2 are locked.

As described above, according to the frame attaching / detaching jig 1 of the present embodiment, the piece attaching / detaching jig 1 is overlapped with the piece 2 so that the shaft portion 12 is inserted into the inside of the piece 2 so as to be light. By simply pushing in, the first moving member 25 and the second moving member 26 are moved outward to release the insertion state of the connecting protrusions 253 and 263, and the piece 2 is moved to another piece. It can be made a state which can be removed from the body 2 or connected to another piece 2. Thereby, even when the belt length cannot be adjusted by the store salesperson in the case of mail order sales, any user who has purchased the product can easily adjust the length of the wristwatch belt or the like.
Further, since the base portion 11 of the frame attaching / detaching jig 1 is formed of a transparent or translucent material, the base portion 11 of the piece attaching / detaching jig 1 is transparent when superimposed on the piece 2. Alternatively, the positions of the insertion holes 234a and 241a of the frame body 2 can be visually confirmed through the semi-transparent base portion 11, and the frame body attaching / detaching jig 1 can be easily positioned.
Further, when the base portion 11 of the frame body attaching / detaching jig 1 is overlaid on the frame body 2, the hanging portions 13 are respectively arranged outside both side portions of the frame body 2. It becomes easy to position in the width direction.
Further, when the plurality of pieces 2 are continuously removed from the band 10, the hanging portion 13 serves as a guide so that the piece attaching / detaching jig 1 is moved to the next piece along the connecting direction of the band 10. 2 can be moved smoothly.
Further, the hanging portion 13 of the frame body attaching / detaching jig 1 has a length in the hanging direction longer than the length of the shaft portion 12 in the hanging direction. Thereby, it is hard to get hurt even if the stepping tool 1 is accidentally stepped on.
In addition, the frame body attaching / detaching jig 1 and the frame body 2 to which the attachment / detachment operation is performed can realize easy attachment / detachment of the frame body 2 with a relatively simple configuration. Bands can be provided.
