By pushing and advancing by hand, the sheet fixing wire 2 is pushed into the sheet fixing groove 40 together with the sheet 3 to be fixed.

Hereinafter, a sheet fixing tool according to the present invention will be described based on the illustrated embodiments.
As shown in FIG. 1, the main body 1 of the sheet fastening tool 10 of this embodiment is formed in a substantially rectangular parallelepiped shape having a size of about 115 × 47 cm in length and width and about 34 cm in height. When the main body 1 is viewed from the side, the rear portion is formed in a shape that is slightly inclined downward, so that it is easy to grip and work.
The seat fastening tool 10 has a weight (about 350 g as an example) that is highly stable during traveling and does not shake from side to side.

  The front end face of the main body 1 of the sheet fastening tool 10 is formed in a rectangular cutout shape in which the introduction port 1a of the sheet fastening wire 2 is elongated vertically and the lower end is opened when viewed from the front direction shown in FIG. . As shown in FIG. 3, the wall portion of the introduction port 1a is formed in an arc shape or R shape in which the sheet fixing wire 2 is slippery when seen in a plan view, so that the sheet fixing wire 2 can be easily guided. Yes. Moreover, the steel plate 7 and 7 which protects the surface and slides the sheet | seat stop wire 2 are affixed on the wall part of the introduction port 1a.

When the main body 1 is viewed in the bottom direction shown in FIG. 3, a concave surface portion 1b is formed, and wheels 6a (6b) traveling on the opening edges 43, 43 of the seat fastening groove 4 in the concave surface portion 1b. Two sets of anti-wheel removal wheels 5a (5b) that fit into the grooves 40 inside the opening edges 43, 43 are installed on the front and rear of the seat fixing tool 1 in the traveling direction by the axle.
The anti-wheel removal wheel 5a installed in the front is configured separately from the left and right wheels 6a, 6a, and a part of the anti-wheel removal wheel 5a faces the introduction port 1a of the main body 1 at the rear part. The sheet retaining wire 2 guided to 1a is installed in a position to push the sheet fastening groove 40 below the seat fixing groove 40, and has the effect of preventing the main body 1 from being detached. The sheet retaining wire 2 guided by the introduction port 1a is The effect of pushing down the sheet fastening groove 40 is also achieved.
The rear wheels 6b and 6b and the wheel removal preventing wheel 5b are integrally formed, and are installed in the concave portion 1b of the main body 1 by a common axle.

  As shown in FIGS. 1 and 2, the sheet fastening tool 10 is a sheet in which both side walls rising on both sides of the bottom wall are inclined inwardly in a square shape when viewed in cross section, and the opening 41 is narrow. The sheet fixing groove profile 4 in which the fixing grooves 40 are formed, and a wave shape continuous in the direction in which the same circular wave is alternately reversed on one plane with an amplitude slightly larger than the width dimension of the opening 41. The present invention is applied to a sheet stopper composed of an elastic arc corrugated sheet stopper wire 2 formed.

The sheet fastening tool 10 is used by first pushing one end of the sheet fastening wire 2 into the sheet fastening groove 40 together with the sheet 3 spread over the opening of the sheet fastening groove profile 4. Fix it.
Next, the sheet fixing tool main body 1 is fitted on the end portion of the sheet fixing wire 2 pushed into the sheet fixing groove 40, and the derailment prevention wheels 5a and 5b are fitted into the sheet fixing groove 40, and the wheel 6a and 6b are placed on the opening edges 43 and 43.
Next, the introduction port 1a is opposed to a portion where the sheet fixing wire 2 is exposed to the outside of the sheet fixing groove 40, and the wheels 6a, 6b are placed on the opening edges 43, 43 of the sheet fixing groove member 4. The seat fixing tool body 1 on which is placed is pushed by hand to advance. Then, one mountain and one mountain of the arc corrugated sheet retaining wire 2 successively hit the left and right introduction ports 1a one after another, and the sheet retaining wire 2 is guided into the sheet securing groove 40, and into the sheet securing groove 40. Fixed.
The seat fastening tool 10 according to the first embodiment is implemented with a configuration in which, as shown in FIGS. 8 and 9, for example, a manual operation unit 16 raised upward from the upper surface of the main body 1 is provided. Thus, the main body 1 placed on the opening edges 43, 43 of the sheet fastening groove member 4 can be easily pushed forward.

  Incidentally, the sheet fixing groove member 4 has substantially the same shape and size as the existing groove member, and is disclosed in, for example, Japanese Patent Application Laid-Open No. 2003-222106 and Utility Model Registration No. 3116845 as shown in FIG. It is possible to press and connect to the pipe member 9 (or other sheet fastening groove shape member) using the wedge type connecting fitting 8 or the like. Therefore, on both side walls of the sheet fastening groove member 4, support pieces 42, 42 protruding outward in an arc shape are formed continuously in the longitudinal direction of the sheet fastening groove member 4.
