Example 1
Embodiment 1 of the present invention will be described below with reference to FIGS. The sheet fixture is formed by bending a brass plate into a substantially V-shape, connecting the base portions of each other, and forming a pair of sandwiching pieces 1 and 1 each having an open end, and an annular stainless steel material. The rope attachment portion 3 is formed by bending the wire attachment portion, and the rope attachment portion 3 is attached to the base portion of the seat attachment portion 2, and a pair of spring members are formed at the distal end portion of the sheet attachment portion 2. Locking pieces 4 and 4 are provided.

  The seat mounting portion 2 is configured to sandwich a huge portion 7 formed by sandwiching a reinforcing rope 6 at the edge of the seat 5 from both sides with a pair of sandwiching pieces 1, 1 and attach and fix the fixture to the seat 5. A reinforcing rib 8 formed by bending both sides and a reinforcing rib 19 formed by pressing at the center are provided to prevent the pair of sandwiching pieces 1 and 1 from opening. Yes. The rope attachment portion 3 is for attaching a rope, a wire or the like (not shown) for expanding and fixing the sheet 5, and the pair of locking pieces 4, 4 constitute a means for preventing the sheet 5 from coming off. To do.

  The locking piece 4 is formed in a substantially square shape and is arranged inside the holding piece 1 so that the tip thereof protrudes obliquely toward the base portion of the holding piece 1. Further, the base of the locking piece 4 is clamped by the bent piece 9 formed at the tip of the holding piece 1, and the projection 10 formed on the bent piece 9 is fitted into the mounting hole 11 of the locking piece 4. Are attached. Further, as shown in FIG. 3, the projection 10 of the bent piece 9 is formed to have a smaller diameter than the mounting hole 11, and there is a minute gap between the locking piece 4 and the bent piece 9. For this reason, the locking piece 4 is held in a loosely fitted state so that the ends of the pair of locking pieces 4, 4 can be opened and closed in the direction in which the sheet 5 is sandwiched.
