A STRAP TENSIONER

摘要

A strap tensioner of the type with a pivot arm (1) serving as a handle which is mounted in a frame (2) serving as a guideway for the strap (16) intended for tightening, the pivot arm having two bars over which the strap (16) intended for tightening is designed to be laid. The main object of the invention is to provide a strap tensioner of the above-mentioned type which is able to bring relatively high levels of traction force to bear on the strap intended to be tensioned, both during tightening and in the locked state, without this strap being subjected to wear due to mechanical action between the tensioning arrangement and the strap. According to the invention the frame (2) has a check (38) past which there runs the tensionable strap section (16) of the strap in question, which co-acts with the pivot arm (1), and a clamping device (27) which extends across the frame and moves the plane of the strap, and which is designed to clamp the strap securely against the check in one position, the "clamped position", and to allow the strap to pass freely between the clamping device and the check in another position, the "free position", the clamping device being designed to be moved by the pivot arm into its free position when the pivot arm is pivoted into its locking position, and having a catch (29) which holds it in the free position when the pivot arm is moved back again towards its releasing position.
