Abstract
In one embodiment, a lock mechanism includes a control element arranged for rotation about an axis between an active position and an inactive position. The control element includes a control head having one or more axially extending projection(s). The lock mechanism further includes a lock element that is axially aligned with the control element and includes a lock element head. The lock element head has one or more axially extending projection(s). The projection(s) of the control head and the projection(s) of the lock element head are arranged such that in the active position, the lock element and control element are held apart by the projections, and such that in the inactive position, the projections can mesh together to permit axial movement of the lock element relative to the control element.

A lock mechanism comprising a control element arranged for rotation about an axis between an active position and an inactive position, the control element including a control head having at least one axially extending projection extending along the axis, the lock mechanism further comprising a lock element that is axially aligned with the control element and includes a lock element head, the lock element head having first and second opposed axial ends along the axis and at least one axially extending projection extending along the axis from an axial end face of the first axial end and toward the control head of the control element, the projection(s) of the control head and the projection(s) of the lock element head arranged such that in the active position, the lock element and control element are held apart by the projections and in the inactive position, the projections can mesh together to permit axial movement of the lock element relative to the control element, wherein the lock element comprises an elongate body having the at least one projection at the first axial end and a lock bolt at the second axial end, and wherein the lock mechanism includes a spring to urge the control element and lock element apart.
A lock comprising:
- a keep;
- and
- a lock mechanism comprising a control element arranged for rotation about an axis between an active position and an inactive position, the control element including a control head having at least one axially extending projection, the lock mechanism further comprising a lock element that is axially aligned with the control element and includes a lock element head, the lock element head having first and second opposed axial ends along the axis and at least one axially extending projection extending along the axis from an axial end face of the first axial end and toward the control head of the control element, the projection(s) of the control head and the projection(s) of the lock element head arranged such that in the active position, the lock element and control element are held apart by the projections and in the inactive position, the projections can mesh together to permit axial movement of the lock element relative to the control element, wherein the lock mechanism includes a spring to urge the control element and lock element apart;
- the lock element comprising a lock bolt at one end, opposite the lock element head, for engaging the keep of the lock and withdrawal rod for withdrawing the lock element when the control element is in the inactive position.
A locking system for securing doors or windows of a building, the locking system incorporating a controller and at least one lock mechanism, each lock mechanism comprising:
- a control element arranged for rotation about an axis between an active position and an inactive position, the control element including a control head having at least one axially extending projection, the lock mechanism further comprising a lock element that is axially aligned with the control element and includes a lock element head, the lock element head having first and second opposed axial ends along the axis and at least one axially extending projection extending along the axis from an axial end face of the first axial end and toward the control head of the control element, the projection(s) of the control head and the projection(s) of the lock element head arranged such that in the active position, the lock element and control element are held apart by the projections and in the inactive position, the projections can mesh together to permit axial movement of the lock element relative to the control element, and wherein the lock element comprises an elongate body having the at least one projection at the first axial end and a lock bolt at the second axial end, and wherein the lock mechanism includes a spring to urge the control element and lock element apart;
- the controller being adapted to control each lock mechanism.
