Abstract

In a clamping lock for antiskid chains with a housing supporting an actuating lever which has a catch position in which a clamping rope which can be pulled through a housing opening into the housing for purposes of clamping can be locked against its clamping direction and has a release position in which the clamping rope can be released from this locking, the clamping rope is connected inside the housing to a winding device which is pretensioned in the wind-up direction.

Claims22

Dependent claims

A clamping lock for an antiskid chain comprising:

a housing having a housing opening;
an actuating lever which is fitted to said housing having a catch position in which a clamping rope which can be pulled through said housing opening into the housing for purposes of clamping can be locked against its clamping direction,
said actuating lever having a release position in which the clamping rope can be released from said locking;
a winding device;
and
said clamping rope being connected inside the housing to said winding device which is pretensioned in the wind-up direction;
the actuating lever being able to also be moved into a third position in which it locks the clamping rope in both of its directions;
a toothing being arranged laterally at the winding roll and which can be brought into a locking engagement with a catch member arranged at the actuating lever or controlled by the actuating lever in the catch position of the actuating lever, the actuating lever cooperating with a locking lever which is movable relative to it, both levers being mounted at the housing so as to be swivelable, and the locking lever being provided with the catch member by which it can be brought into engagement with the toothing in a catch position, while the actuating lever can be moved into its three positions by the user from the outside of the housing;
the locking lever being pretensioned in the engagement position of its catch member with the toothing,
the actuating lever having two projections provided on both sides of a tilting axis on the side of the actuating lever facing the locking lever, the locking lever being swiveled out of engagement with the toothing in the release position of the actuating lever by means of one of the projections and the locking lever can be locked in position in its catch position, in which the catch member engages with the toothing, by means of the other projection in the third position of the actuating lever.
