Title:
AUTOMATIC DIRECTION SWITCHING PENDULUM-TYPE ROTARY DRIVE RATCHET FOR INDIRECT LIVE WIRE
Document Type and Number:
WIPO Patent Application WO/2023/153643
Kind Code:
A1
Abstract:
The present invention relates to a rotary drive ratchet used in a wire grip or tensioner and, more specifically, to an automatic direction switching pendulum-type rotary drive ratchet for an indirect live wire, which is configured to adjust, when winding or unwinding a wire grip or tensioner, the forward or backward rotation of a pendulum drive shaft by means of the operation of an automatic reversing pawl and a pendulum drive shaft operation plate in accordance with a reciprocating motion of a pendulum without the operation of a direction switching lever, so as to enable the forward or backward reversing rotation of the pendulum drive shaft to be automatically performed by means of operating a rotary lever using a stick for an indirect live wire without a separate rotational direction switching operation. In addition, the ratchet is configured such that the pendulum drive shaft is driven by a backstop ratchet ring operated by a multi-angle bundle pawl, so as to enable robust backward rotation prevention and enable robust rotational driving, such as preventing backlash during reversing to backward rotational driving.
