Claims (1)

[Claims for Utility Model Registration] (1) A double arch-shaped spring part consisting of a series of upper arch parts and lower arch parts, having a through space between the two arch parts, and a spring part continuous from the lower end of the arch. and a flange locking member disposed approximately in the center of the double arch spring portion so as to extend from the lower surface side of the lower arch portion to beyond the upper surface of the upper arch portion. A futon clamp comprising a rod and a pressing force setting lever disposed near the top of the flanged locking rod. (2) The pressing force setting lever is pivotally mounted near the upper part of the flange-attached locking rod, and has a plurality of plane parts whose perpendicular distances from the pivot point are different from each other, and the upper arch part is roughly the same as the upper arch part. 2. The futon gripper according to claim 1, wherein the central portion is provided with a flat portion that engages with a flat portion of the pressing force setting lever. (3) A longitudinal through-hole is provided near the top of the flanged locking rod along the axis of the locking rod, and a fulcrum hole communicating with the longitudinal through-hole is located toward the longitudinal through-hole. The pressurizing force setting lever is movable between the fulcrum holes by means of a pin loosely fitted into the hole, and is arranged so as to be freely drivable in each of the fulcrum holes. The futon clip according to claim 1, characterized in that: (4) The flanged locking rod is configured to fit the lower arch into a through hole that is provided in a substantially central portion of the double arch spring portion and aligned with the lower arch and the upper arch. The futon nipper according to any one of claims 1 to 3, characterized in that it is arranged by being inserted so as to extend beyond the upper surface of the upper arch portion from the lower surface side. (5) The flanged locking rod has a substantially U-shape, and the lower arch portion and the upper arch portion are each narrowed on the inside of the U shape at approximately the center of the double arch spring portion. The futon nipper according to any one of claims 1 to 3, wherein the pressure setting lever is rotatably pivoted to an inner upper end portion of the U-shape.
