Abstract

PURPOSE:To smoothly unwind a wound belt by small force by rotationally movably journaling the extreme end part of a winding lever with an annular flange part projectingly provided on the circumferential edge part of a journaling hole journaling a winding shaft in a fastener main body. CONSTITUTION:For unwinding a belt V1 wound around a winding shaft 23, a ratchet engaging plate 18 is pulled backward against a compression spring 21 by means of a pulling piece 18b provided on the ratchet engaging plate 18, a winding lever B is rotationally moved counterclockwise, and the engaging plate 18 is engaged with the engaging groove 12 of a fastener main body A. In this condition, an engaging plate 5 for preventing reverse rotation is disengaged out of a ratchet, 25. Hereby, the belt V1 wound around the winding shaft 23 can be unwound. At this time, reaction of the restoring force of the compression spring 21 energizing the ratchet engaging plate 18 to the engaging groove 12 is applied on an annular flange part 4 projectingly provided on the circumferential edge part of a journaling hole 3 of the fastener main body A, and not applied on the winding shaft 3 at all. Hence the belt V1 can be smoothly unwound by small force.

In the conventional belt tightening tool, the winding lever is directly rotatably supported on the winding shaft supported by the tightening tool body. Therefore, when the ratchet engagement plate provided on the take-up lever is engaged with the engagement groove provided on the fastener body in order to make the belt wound around the take-up shaft ready for rewinding, The reaction force of the restoring force of the biasing means (spring) that biases the ratchet engagement plate in the ratchet direction acts on the winding shaft. This reaction force becomes a rotational resistance of the rotating shaft when the belt is rewound, and the rotating force of the take-up shaft becomes large, which requires a large force to rewind the belt. Will be described in more detail in the description part of the embodiment of.

1. A ratchet is integrally attached to a take-up shaft, and the take-up shaft is provided at one longitudinal end of a fastener main body provided with a reverse rotation preventing engagement plate biased in the direction of the ratchet. At the tip of the winding lever, which is supported, is provided with a ratchet engaging plate that is biased in the direction of the ratchet and engages with it,
A cam portion for retracting the reverse rotation preventing engagement plate is provided, and the tightening tool main body is provided with the winding lever when the winding lever is rotated beyond the winding rotation end. An engaging groove for engaging the ratchet engaging plate provided on the lever is provided, and when the winding lever is rotated in the standing direction from the fallen state, the ratchet engaging plate attached to the ratchet engaging plate and the ratchet are Engagement, the winding shaft rotates in the same direction and the belt is wound, and the ratchet engagement plate is retracted against the biasing force, and the winding lever is moved beyond the winding rotation end. When the ratchet engagement plate is engaged with the engagement groove of the fastener body by further rotating in the winding direction, the cam portion at the tip of the take-up lever causes the reverse rotation prevention engagement plate to move. The belt wound on the take-up shaft is wound by pushing it back. In a belt tightening tool using a ratchet mechanism having a structure capable of performing an operation, an annular flange portion is projected on a peripheral edge portion of a support hole for supporting the winding shaft in the tightening tool body, and the annular flange A belt tightening tool using a ratchet mechanism, characterized in that a tip end portion of the winding lever is rotatably supported by a portion.
