Has been.

  Such a locking part 54 and a locking receiving part 64 are such that the tip of the locking part 54 in the first clamping part 5 becomes closer to the first clamping part 5 as the second clamping part 6 approaches the overlapping direction. The first erected plate 52 is in the width direction (arrow) while the taper 54a of the locking portion 54 is in sliding contact with the corner portion formed by the locking receiving surface 64a and the side surface 62a in the second clamping portion 6. (X direction) bends outward and enters the latch receiving portion 64. The first standing plate 52 returns to the natural state. And the latching surface 54b of the latching | locking part 54 and the latching receiving surface 64a of the latching receiving part 64 are opposingly arranged. Thus, the locking portion 54 is locked to the locking receiving portion 64, and the elastic body 3 is fixed (mainly fixed) to the belt body 2 by the first clamping portion 5 and the second clamping portion 6.

  Next, the assembly procedure of the belt 1 will be described.

  First, in the belt main body 2, the elastic body 3 is attached to the belt body 2 so that the adhesive layer 31 of the elastic body 3 is opposed to the belt main body 2 at both ends (positions straddling the slack portion) of the slack portion 20, part of which is slack. The elastic body 3 is superimposed on the belt body 2 and temporarily fixed by pressing against the body 2. At this time, the elastic body 3 is in a natural state.

  Next, the first clamping part 5 is brought close to the elastic body 3, the positional deviation restricting part 53 is inserted into the insertion hole 3 a of the elastic body 3, the second clamping part 6 is brought close to the belt body 2, and the first clamping part The elastic body 3 and the belt body 2 are clamped from the overlapping direction by the 5 and the second clamping unit 6. The locking part 54 of the first clamping part 5 is locked to the locking receiving part 64 of the second clamping part 6. Each convex part 63 bites into the belt main body 2, and the positional deviation of the belt main body 2 in the longitudinal direction is restricted. The elastic body 3 is fixed to the belt body 2 by the first clamping portion 5 and the second clamping portion 6. Thus, the belt 1 is assembled.

  The belt 1 assembled in this way is supported at both ends by a pair of support portions. At this time, the belt body 2 is pulled in the longitudinal direction (arrow Y direction), the elastic body 3 is expanded, and a contraction force is generated in the elastic body 3, whereby the belt body 2 is elastic except for the slack portion 20. By being pulled by the contraction force of the body 3, tension is applied to portions other than the slack portion 20 of the belt body 2. In this way, looseness of the belt body 2 other than the slack portion 20 is eliminated. Therefore, for example, when the belt 1 is used for restraining the luggage or laying on the front of the shelf on which the article is displayed, the looseness of the parts other than the slack part 20 is eliminated, and the collapse of the article and the falling of the article are prevented. Can be achieved. In other words, earthquake countermeasures can be taken.

  Alternatively, in a state where the belt main body 2 is supported by the pair of support portions, that is, in a state where the belt main body 2 is already installed, the elastic body 3 is extended in the longitudinal direction (arrow Y direction), and the longitudinal direction thereof is increased. You may fix to the belt main body 2 with the fixing tool 4 in the state made to produce force so that it may shrink | contract.

  According to the above-described embodiment, the elastic body 3 can be fixed to the belt main body 2 by a simple operation of holding the elastic body 3 and the belt main body 2 by the fixing tool 4. Accordingly, it is possible to improve the workability required for fixing the elastic body 3 to the belt body 2.

  In addition, this invention is not limited to the said embodiment, Including other structures etc. which can achieve the objective of this invention, the deformation | transformation etc. which are shown below are also contained in this invention. For example, in the embodiment described above, the locking portion 54 is formed in the first clamping portion 5 and the locking receiving portion 64 is formed in the second clamping portion 6. However, the present invention is not limited to this, and the first clamping portion is formed. An engagement receiving portion may be formed on the portion 5, and an engagement portion may be formed on the second sandwiching portion 6.

  Further, in the present embodiment, an example in which the pair of fixing tools 4 and 4 are fixed across the slack portion 20 of the belt body 2 is described, but the present invention is not limited thereto, Two or more may be provided. In that case, the fixture may be provided, for example, in the central portion of the elastic body 3 in the longitudinal direction. According to this, the slack portion 20 of the belt body 2 can be dispersed in a plurality of locations without being concentrated in one place.

  Next, a modification of the belt fixture according to the embodiment of the present invention will be described with reference to FIG. FIG. 6 is an exploded perspective view showing a modified example of the belt fixture according to the embodiment of the present invention. In FIG. 6, parts having the same configurations or functions as those of the above-described embodiment are denoted by the same reference numerals and description thereof is omitted.

The invention is not limited to this, and as shown in FIG. 6, the longitudinal dimension of each first standing plate 52 is formed to be shorter than the longitudinal dimension of each second standing plate 62. The two standing plates 62 are provided with a notch portion 65a formed by cutting out the side surface 62a on the outer side in the width direction of the second standing plate 62 so that the first standing plate 52 can be accommodated. It may be.

  Further, in the belt 1 according to the embodiment of the present invention, each convex portion 63 formed in the second sandwiching portion 6 has an inclination of the inclined surface 63a on the one side in the longitudinal direction and the other side in the longitudinal direction. The slope 63b is formed so that the slope is substantially the same slope, but the present invention is not limited to this, and as shown in FIG. 6B, each convex part 63 'in the second sandwiching part 6' The slope 63a on one side in the longitudinal direction from the top may be formed to be steeper than the slope of the slope 63b on the other side in the longitudinal direction. As shown in FIGS. 6A and 6B, the convex portion 63 ′ is provided with a steep slope 63a on the center side in the longitudinal direction (arrow Y direction) of the second flat plate portion 61, and the second A slope 63 b is provided on the end side in the longitudinal direction of the flat plate portion 61. By forming such a plurality of convex portions 63 ′, it is possible to further restrict the positional deviation of the belt body 2 with respect to the fixture 4.
