結を解除することが不可能であつた。 As shown in FIG. 1, when the pieces are connected, the pin holes of one piece and the other piece communicate with each other, and the pin hole 2 becomes a through hole orthogonal to the longitudinal direction of the band. Insert the connecting pin 2 into the connected pin hole 3 as described above, and insert the piece 1.
A band in which the two are connected by a connecting pin 2 is used as a high-quality band, but the pin hole 3 into which the connecting pin 2 is inserted is visible on the side of the band, which is unfavorable in terms of appearance. Although not shown, it was also possible to use a spring bar as the connecting pin and cover the side of the band so that the pin hole was not visible, but in this case it was impossible to disconnect the pieces. .

バンド構造を得ることを要旨としている。 The object of the present invention is to improve the drawbacks of the prior art described above, and to provide a watch band in which the pieces can be easily connected and separated, and the pin holes are not visible and the appearance is excellent. The pieces are connected by connecting pins so that the pin holes are not visible from the outside of the band, a shape memory alloy is used for the connecting pins, and the shape memory alloy is deformed by heating it from the outside of the band to above its transformation point. , the gist is to obtain a band structure in which the tips of the connecting pins are allowed to escape from the pin holes of one of the pieces, thereby separating the pieces.
なお、形状記憶合金は温度により結晶構造が変
る性質があり、高温で安定な原子配列をとつた時
の相を母相、低温で安定な原子配列をとつた時の
相をマルテンサト相という。 Note that shape memory alloys have the property that their crystal structure changes depending on the temperature, and the phase when the atomic arrangement is stable at high temperatures is called the matrix phase, and the phase when the atomic arrangement is stable at low temperatures is called the martensate phase.
この形状記憶合金は、母相において、ある形状
にした後、低温側にして形を変えても、再度変態
点以上に加熱し母相にすると、もとの形状に戻
る。 Even if this shape memory alloy is formed into a certain shape in its parent phase and then changed to a lower temperature, it will return to its original shape if it is heated again to a temperature above the transformation point to form the parent phase.
この発明は、形状記憶合金の上記の性質を利用
したものである。 This invention utilizes the above properties of shape memory alloys.

Since the spring constant k 1 of is made smaller than the spring constant k 2 of the spring 12, the elastic body 10 is influenced by the spring 12 and becomes stretched as shown in FIG. A coiled portion of the elastic body 10 formed by bonding the shaped alloy 11 and the spring material 12 is inserted into the pin hole 9, one end of the coiled portion is fixed to the inner wall of the pin hole 9, and the other end of the coiled portion is fixed to the inner wall of the pin hole 9. The tip 13a of the connecting pin 13 is inserted into the pin hole 7 of the cutout 6. FIG. 6 is a sectional view of a main part showing a state in which two pieces of elastic body 10 are inserted into pin holes 9 and pin holes 7 as described above to connect two pieces, and FIG. The perspective view shows a state in which pieces are connected.

きる。 Next, to separate the pieces, heat is applied from the outside of the band 4, and when the shape memory alloy 11 is heated above its transformation point, the crystal structure changes to the matrix, the spring constant increases to k 3 , and the spring Since the spring constant k 2 of 12 is larger than that of 12, it tries to change to its original shape, that is, a contracted state. As a result, as shown in FIG. 7, the tip 13a of the connecting pin 13 escapes from the pin hole 7 of the piece 6, so that the pieces can be separated.

数k2より小さいk1となるため、バネ１２によつて
弾性体１０は元の伸びた状態に戻る。 Note that when the heat is stopped and the temperature returns to room temperature, the crystal structure of the shape memory alloy changes to a martensitic phase, and the spring constant of the elastic body 10 becomes k1 , which is smaller than the spring constant k2 of the spring 12. The spring 12 causes the elastic body 10 to return to its original stretched state.
なお本実施例におけるピン孔９は、凸出部８の
両側壁に穿設した貫通していない２つのピン孔で

了する。 FIGS. 8 and 9 are sectional views of main parts showing a second embodiment of the present invention, in which an elastic body 15 made of a shape memory alloy and an ordinary coil spring 16 are arranged before and after a connecting pin 14. To connect the pieces, insert the elastic body 15 into the pin hole 18 of one piece 17, and insert the elastic body 15 into the pin hole 2 of the other piece 19.
0, with the coil spring 16 and the connecting pin 14 inserted, the recessed part and the protruding part of the two pieces 17 and 19 are assembled, and the pin hole 18 and the pin hole 20 are made to communicate with each other. The pin is pushed through the pin hole 18, and the connection between the pieces 17 and 19 is completed.
なお、このとき弾性体１５の結晶構造はマルテ

２５に挿通し、連結が完了する。 10 to 12 are main part sectional views showing a third embodiment of the present invention, and one end of an elastic body 21 made of a shape memory alloy has a hook portion 22a at the tip.
A connecting pin 22 having a diameter is attached. The other end of the elastic body 21 is fixed to the pin hole 24 of the piece 23,
As shown in FIG. 10, a portion of the connecting pin 22 protrudes from the pin hole 24. Piece 23
To connect the 11th piece 26 to the 11th piece, push the connecting pin 22 into the pin hole 24, incorporate the protruding part of the piece 23 and the recessed part of the piece 26, and make the pin hole 24 and the pin hole 25 communicate with each other. As shown in the figure, elastic body 2
The connecting pin 22 pushed to the position 1 is inserted into the pin hole 25 of the other piece 26, and the connection is completed.

る必要がある。 In the case of the third embodiment, even when the temperature returns to room temperature and the crystal structure changes from the parent phase to the martensitic phase, no external force is applied, so the elastic body 21 remains in a contracted state. Therefore, when connecting the pieces next time, it is necessary to pull out the connecting pin 22 using the hook portion 22a and cause the elastic body 21 to undergo plastic deformation.

It has a completely new structure that has never been seen before. Further, the temperature of the transformation point of the shape memory alloy can be arbitrarily set by changing the proportion of the mixture, so that the high temperature does not affect the surface of the band.
