<p>PURPOSE:To prevent noise due to contact and friction of connecting members by fixing a belt-shaped member, which connects each shoe, to one ends opposed to each other of the adjacent shoes. CONSTITUTION:Each one end of a broad belt-shaped member 8, having not expansibility but flexibility, is inserted into a groove 6, formed in squared shape with one side open, provided in front and rear side end parts of a shoe main unit 1. Two or more bolt holes 9 are drilled toward the upper from bottom surface front and rear ends of the shoe main unit 1 of each shoe 7, and the upper end of these bolt holes 9 penetrates through the one side-open squared- groove 6 to reach its upper. Further a bolt 10 is screwed respectively through each bolt hole 9 to the upper end thereof in the above by penetrating through the belt-shaped member 8 in each groove 6 of squared shape with one side open. In such a way as mentioned, the many shoes 7 are connected by fixedly inserting both ends of the belt-shaped member 8 into each groove 6 of squared shape with ore side open.</p> |
