    System for securing a sign to a support surface
    FIELD OF THE INVENTION
    The present invention relates to a system for securing a sign to a support surface, More specifically the inventic«! relates to a system comprising a magnetically releasable lock adapted to automatically lock mutually displaceable surface portions together.
    BACKGROUND OF THE INVENTION
    Signs, name plates and the like often need to be mounted on a base secured to a door or wall. These are prone to be subjected to unwarranted removal. This is particularly so with name piates which can readily be used by others. The unauthorized removal of name piates has led to considerable inconvenience andexpense in providing replacements;
    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. it is therefore an object of the present Invention to provide a system: for securing a sign to a support surface, wherein the sign can be readily secured and which is not prone to unauthorized removal.
    The object of the invention is to provide a system in which the locking means is not visible and an externa! magnetic device suitably designed must be applied to a predetermined area of;the assembly in order: to;:remove the sign-carrying part from its base,: A further object of the invention is ίο provide a system in which a sign-carrying part wi automatically lock itself when repositioned on the base of the name plate assembly
    SUMMARY OF THE INVENTION
    The system according to the invention is characterised in that the sign device comprises a magnetically releasable lock adapted to automatically lock mutually displaceable surface portions^ i^getherj The system ensures locking of the two mutuailydisplaceabie portions without the visible Information-carrying part being disfigured. Unauthorized persons cannot remove the information-carrying part without having knowledge about the location of the magnetically releasable lock.
    Specifically the present invention provides a system for securing a sign to a support surface, said system comprising·. • a sign-carrying part for releasable attachment on a mounting part, said sign-carrying part having a front side for holding the sign and a back side provided with a track that loosely høids a locking plate, said track providing a compartment for the locking plate with an opening distal to the back side of the sign-carrying part, said locking plate provided with a protrusion that protrudes beyond the opening of the track when the locking plate is resting on the inner surface of the track distal to the back side; * a mounting part configured to be fixedly attached to a support surface, said mounting part having a backside for mounting it on the support surface, and a front side with a track for receiving the protrusion of the locking plate thereby preventing lateral displacement/movement of the sign-carrying part; wherein the mounting part and the sign-carrying part further comprise mutually cooperating profile portions, said locking piate being magnetic and in an a locking position when not being influenced by an external magnetic force from the front side of the sign that is greater than the magnetic force between the locking plate and a part of the front side of the mounting part, said locking plate being in an open position when influenced by said external magnetic force thereby allowing the sign-carrying part to be released from said mounting part.
    Preferably the track of the mounting part includes a magnetic piece for exerting the magnetic force between the locking plate and a part of the front side of the mounting part. The sign-carrying part and/or the mounting part are preferably produced from a nonmagnetic material. such as aluminum.
    In a preferred embodiment of the present invention the mutually cooperating profile portions are located in the peripheral region of the sign-carrying part and the mounting part. Accordingly, the tracks of the sign-carrying part and the mounting part are located in the central regions thereof.
    In a particularly preferred embodiment the cross section of the track of the sign-carrying part takes the form of a quadratic tunnel closed in the ends and with a longitudinal opening in the roof section of said tunnel to ensure that the locking plate is slidable in the tunnel between said ends, and wherein the track for receiving the protrusion of the locking plate is aligned and parallel with the longitudinal opening. Preferably the roof section is in contact with the uppers section of the track of the mounting part when the system is assembled. It is also preferred that the opening of the perfectly fits the protrusion of the opening of the track of the sign-carrying part. Likewise, the protrusion of the Socking plate is preferably of quadratic shape, whereas the locking plate is of a rectangular shape.
    The system of the present invention comprises a sign or name plate mounted on a base together with magnet means whereby the name plate is secured to the base and is releasable from the base only when the magnet means is made operable by an authorized person. While the magnet within the sign or name plate assembly is in the unlocked position, the sign-carrying part can be wristed out of engagement with the mounting part. Without the use of an operative magnet, the part remains securely locked. in some applications of the invention where an electrical supply is available, such as for illuminating a directory panei board, electro-magnets can be employed tor locking and unlocking the parts.
    The present invention, therefore, provides a relatively cheap and practical means : of protecting signs and name plates from unwarranted removal from the baso on which they are mounted.
    BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a part perspective view of a system according to the present invention with the sign-carrying part removed from the mounting part.
    FIG. 2 is a part perspective view of the system of FIG.2, which has been disassembled. DETAILED DESCRIPTION OF THP INVENTION
    The system illustrated in Figs. 1-2 comprises a sign-carrying part (1) for releasable attachment on a mounting part (2), said sign-carrying part (1) having a front side for holding the sign and a back side provided with a track (3) that loosely hoids a locking plate (4), said track providing a compartment {5) for the locking plate (4) with an opening (6) distal to the back side of the sign-carrying part, said iocking piate (4) provided with a protrusion (7) that protrudes beyond the opening {6} of the track (3) when the iocking plate is resting on the inner surface of the track (3) distal to the back side. The mounting part (2) configured to be fixedly attached to a support surface, said mounting part (2) having a backside for mounting it on the support surface, and a front side with a track (3') for receiving the protrusion {7} of the iocking piate (4) thereby preventing lateral displacement/movement of the sign-carrying part (1).
    As shown in Figs. 1-2 the mounting part (2) and the sign-carrying part (1) further comprise mutually cooperating profile portions (8,8 9,9’), said iocking plate {4} being magnetic and in an a iocking position when not being influenced by an externa! magnetic force from the frail side of the sign that is greater than the magnetic force between the locking plate (4) and a part {10} of the front side of the mounting part, importantly the iocking plate (4) being In an open position when influenced by said external magnetic force thereby allowing the sign-carrying part (1) to be released from said mounting part (2). Fig. 2 further shows end caps (11) and screws (12) for fastening these to the ends of the mounting part (2) and the sign-carrying part {1} in order to prevent that the parts may slide longitudinally relative to each other.
    The sign-carrying part {1) may further comprise an information-carrying part in the form of a raii. The mounting part (2) and the sign-carrying pad (1) are preferably of the same length.
