Abstract
Provided is a telescopic lock that can be fixed to a variety of closures of different configurations to thereby provide another closure protection measure.
Claims19
A lock, comprising:
- first and second elongated lock members wherein (i) the first member fitting telescopically into the second member and the two members jointly define an axis extending between a first end of the first member and a second end of the second member, and (ii) the two members can axially displace with respect to one another between one or more locking states and one or more open states, the first member has at least one opening in sidewalls thereof and the second member has at least one set of recesses corresponding to each of the at least one opening, the opening being aligned with one of the corresponding recesses in the one or more locking states and being configured to accommodate a blocking element;
- an electrically-driven blocking arrangement that is (i) housed within one or both of the two members, and (ii) having a blocking state, in which relative axial displacement of the two lock members is blocked, and a facilitating state, in which the relative axial displacement is enabled;
- and
- an electric control mechanism associated with the blocking arrangement for causing said arrangement to switch between the blocking and the facilitating states,
- the blocking arrangement comprises a slider that is axially displaceable between (i) the blocking state in which the slider obstructs the radial movement of the blocking element out of the recess to thereby maintain the first and second members in the locking state and (ii) the facilitating state in which the blocking elements can radially move out of the recess to thereby permit relative axial displacement of the first and second members into the open state;
- the slider being associated with an urging element, that urges the slider into the blocking state;
- and
- a solenoid with a solenoid plunger switchable between a pulled-in and a pushed-out positions and having a leading element or portion that defines a leading end that bears on the slider to displace the slider into the facilitating state.

- an electric control mechanism associated with the blocking arrangement for causing said arrangement to switch between the blocking and the facilitating states
- the blocking arrangement comprises a rotating element that can rotate between a blocking state, in which the rotating element obstructs the radial movement of the blocking element out of the recess to thereby maintain the first and second members in a locking state, and a facilitating state, in which the blocking elements can radially move out of the recess to thereby permit axial relative displacement of the first and second members into an open state;
- and
- an electric motor coupled to said rotating element for causing the rotating element to rotate between the blocking and the facilitating states.

- an electric control mechanism associated with the blocking arrangement for causing said arrangement to switch between the blocking and the facilitating states;
- and
- one or more radially-urged and radially displaceable pins being part of or being associated with said first member, said second member comprises corresponding one or more pin-receiving recesses formed in internal walls thereof that in the locked state align with and accommodate heads of the pins;
- said pin-receiving recesses being configured to engage the pin head in a manner such as to permit inward radial displacement of the pins upon relative displacement of the two lock members in one direction and not upon the opposite direction.
