Abstract
An electrically actuable furniture locking device includes a locking housing, a locking pin and an indicator element. The locking housing is provided with two introduction openings for a locking pin. In the locking housing, a locking slide is arranged to be actuated electromagnetically and adjusted from a locking position into an unlocking position. A lever armature, which can be connected to the locking slide, can be connected to the locking slide such that it can be optionally switched over for closed-circuit or open-circuit operation. The locking device permits an arrangement adaptable to various installations, as well as monitoring of the open and closed states and optionally closed- and open-circuit operations.
Claims22
A locking device for furniture, said locking device having:
- a locking element affixable to a first furniture part, said locking element comprising a locking pin;
- a locking-element socket affixable to a second furniture part, said locking-element socket comprising a locking housing containing a locking slide, which is movable electromagnetically from a locking position that locks the locking element, into an unlocking position that unlocks the locking element, said locking-element socket further comprising a first introduction opening, and a second introduction opening disposed substantially perpendicular to said first introduction opening, said locking slide having a first socket and a second socket, each of said first introduction opening, second introduction opening, first socket and second socket intended for said locking pin, and
- a monitoring device, which comprises an indicator element arranged at a point of intersection substantially coincident of axes of intersection of each introduction opening of said locking housing and each socket of said locking slide, respectively.
A locking device for locking and unlocking two components moveable relative to one another, in particular doors or drawers of furniture, said locking device having:
- a locking element affixable to a first component, said locking element comprising a locking pin having a longitudinal axis, and
- a locking-element socket affixable to a second component and movable from a locking position that locks the locking element, into an unlocking position that unlocks the locking element, said locking-element socket comprising a locking housing containing an electrically actuable locking slide having a first socket and second socket intended for said locking pin,
- and setting relative positions of interacting locking parts of said locking pin and of said locking slide optionally sets an open-circuit operation, in which said locking pin is locked when an actuation device has not been supplied with current, and optionally sets a closed-circuit operation, in which the locking pin is unlocked when said actuation device has not been supplied with current.
