Abstract
The invention provides a lock body having a keyway and a throughbore parallel to the keyway with the throughbore having two portions separated by a shoulder. A first cable passes through the throughbore, the first cable having a knob at one end and a chevron at a second end. A second cable depends from and is attached to the lock body. The cable body also has a bolt that is biased partially into the first portion of the throughbore. The keyway has a plug that is rotatable with the proper key to retract the bolt from the throughbore. The chevron can pass by the bolt in an axial first direction by urging the chevron and allowing the taper to move the bolt transversely against the bias, but not in a second axial direction. A base accommodates the lock body and cables and is captured by the second cable.
Claims19
A cable lock comprising:
- an elongate cable with a first end having a knob, and a second end terminating in a chevron, with the chevron having a tapered end and a flat transverse back face;
- a lock body having a first end and a second end and having a keyway and a cylindrical throughbore parallel to the keyway, the throughbore extending from the first end to the second end and having a first portion and a second portion separated by a shoulder;
- the keyway having a plug that selectively rotates with a proper key;
- a bolt transverse to the throughbore and retractably biased into the throughbore first portion and selectively retractable against the bias out of the throughbore first portion by rotation of the plug;
- wherein in a first state, the cable second end is accommodated in the throughbore second portion and the cable extends through the throughbore first portion and out of the lock body first end;
- and
- wherein in a second state the cable extends through the throughbore second portion, out of the lock body second end, and the cable first end and the cable second end are captured in the first portion of the throughbore between the bolt and the shoulder with the bolt cooperating with the flat transverse back face of the chevron.
A twin cable lock for securing equipment comprising:
- a lock body having a first end and a second end and having a keyway and a cylindrical throughbore extending through the lock body from the first end to the second end with an axis parallel to the keyway, the throughbore having a first portion and a second portion separated by a shoulder;
- a first elongate cable extending through the throughbore with a first end having a knob, and a second end terminating in a chevron, with the chevron having a tapered end and a flat transverse back face;
- a second cable having a first end and depending from and attached to the lock body first end at the second cable first end;
- the lock body also having a bolt that is retractably biased into the first portion of the throughbore transverse to the throughbore axis;
- the keyway having a plug that is rotatable with the proper key to retract the bolt from the throughbore against the bias;
- wherein the chevron can pass by the bolt as the chevron moves axially in the throughbore in a first direction by the chevron tapered end urging the bolt out of the throughbore against the bias, but the chevron cannot pass by the bolt as the chevron moves axially in the throughbore in a second direction without the bolt being retracted by the plug.
