BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a sign device comprising a mounting part and an information-carrying part capable of being pushed onto said mounting part, wherein the mounting part and the information-carrying part comprise mutually cooperating profile portions having the effect that the pushing of the information-carrying part onto the mounting part can only be performed during mutual displacement of substantially planar, mutually abutting surface portions on the mounting part and the information-carrying part, respectively.
BACKGROUND ART
Various sign devices of the above type are known. Such signs are used both as permanent signs and as signs, where the user according to his wishes can replace the information-carrying part with another information-carrying part. These sign devices are generally used without any locking of the information-carrying part in relation to the mounting part, for which reason unauthorized persons can easily remove the information-carrying part. Different methods have consequently been used for locking the two parts together, but the previously known methods have not proved fully satisfactory, either because the information-carrying part has been disfigured by visible screws or because unauthorized persons have nevertheless been able to release the fastening mechanism concerned.
DESCRIPTION OF THE INVENTION
The sign device according to the invention is characterised in that the sign device comprises a hidden magnetically releasable lock adapted to automatically lock the mutually displaceable surface portions together in the pushed-on state of the information-carrying part. As a result a sign device is provided ensuring locking of the two mutually displaceable portions without the visible information-carrying part being disfigured. As a further result, unauthorized persons cannot remove the information-carrying part without having knowledge as to how the magnetically releasable lock is situated, and thus how the magnet in question has to be placed to release the lock.
The lock may according to the invention be a tiltably mounted magnetic plate mounted in a first recess in one of the two mutually displaceable surface portions, and the plate may comprise a projection for locking cooperation with a similarly formed second recess in the second of the two mutually displaceable surface portions, whereby the lock may comprise a spring influencing he magnetic plate in such a manner that the projection will automatically be in engagement with the recess in the second of the two mutually displaceable surface portions in their assembled position. A lock is consequently obtained which is particularly simply and easily constructed.
In a particularly advantageous embodiment of the invention the magnetic plate may be of an oblong, rectangular shape and may be bent around a transverse bending line in close proximity to the center of the plate, and the plate may at each longitudinal side comprise a further outwardly extending projection at the bending line, said projections being received in corresponding notches extending in opposite directions from the first recess in one of the two mutually displaceable surface portions, the notches having such a depth in a direction perpendicular to the corresponding surface portion that the plate is supported in the notches with the bending line being approximately flush with the surface of the surface portion.
The projection of the plate for locking the surface portions together may be an outwardly extending narrow flange along one end of the plate viewed in its longitudinal direction, whereby a lock is obtained, in which the projections of the plate for locking cooperation with the corresponding second recess are particularly simple and function easily during displacement of the two mutually displaceable parts in a direction coinciding with the longitudinal direction of the plate.
Furthermore, according to the invention the spring may be a coiled spring, which is fastened, e.g. by soldering, to the plate on the side facing the bottom of the
