Abstract

ABSTRACT OF THE DISCLOSURE
A name plate assembly having invisible locking means re-quiring the use of an externally applied magnet.
The name plate assembly includes the use of a base mem-ber having one or more dovetailed type rails on one face and a name plate having corresponding dovetail recesses for slidingly engaging with the rails of the base member. Mounted on the base member is a first magnet means which normally engage with the name plate to hold the name plate locked securely on the base member. The magnet means can only be disengaged from the name plate by the application to the assembly of a second magnet means withdrawing the firs mag-net means from locking engagement with the name plate.

Description

'~V'^J~

This invention relates to name plate ~ssemblies and par-ticularly to name plates which are slidably mounted on a base and have invisible locking means controlled by the use of a magnet or a system of magnets.
Name plates, particularly those which are mounted on a base secured to a door or wall and those which are mounted on a directory board, are readily subjected to unwarranted removal.
This is particularly so with name plates which can readily be used by othersO The unauthorized removal of name plates has led to con-siderable inconvenience and expense in providing replacements.
The invention consists of a name plate mounted on a basetogether 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. In one example, the name plate base has dovetailed rails on its frame face and the name plate has dovetailed rails on its rear face, the dovetailed rails engaging with each other to permit the name plate to be slidably mounted on the base. One or more metal dowels or magnets are floatably mounted in cavities, half of which are located on the front face of the name plate base with the other half being located on the rear face of the name plate. The two facing halves of the cavities are aligned with each other when the name plate is in its proper position on the name plate base~ The metal dowels or mag-nets are floatably captive in the name plate base and partially drop into engagement in the cavity in the name plate only when the . .
name plate is slidably moved along the base to take up its desired position. In order to permit the name plate to be withdrawn from the base, an external magnet or magnet system must be applied to the upper edge or predetermined area of the base name plate assem-bly in order to raise or unlock the metal dowel or magnet out ofthe cavity in the name plate. While the metal dowel or magnet within the name plate assembly is in the raised or unlockedposition, ~ '1 jJ

the name plate can be slid along and out o~ engagement with the base. Thus, without the use of an operative magnet, the name plate remains securely locked on the base.
In some applications of the invention where an elestri-cal supply is available, such as for illuminating a directory pa-nel board, electro-magnets can be employed for locking and unlock-ing the name plates on their base.
The present invention, therefore, provides a relatively ~heap and practical means of protecting name plates from unwar-rented removal from the base on which they are mounted.
The object of the invention is to provide a lockablename plate assembly in which the locking means is not visible and an external magnetic device suitably designed must be applied to a predetermin0d area of the assembly in order to remove the name plate from its base.
A further object of the invention is to provide a name plate assembly in which a name plate will automatically lock itself when repositioned on the base of the name plate assembly.
~ ~urther object o~ the invention is to provide means for locking a multiple of name plates on a base or directory board.
These and other objects of the invention will be apparent from the following detailed specification and the accompanying drawings in which:
Figure 1 is a part perspective view of a name plate as-sembly according to the present invention with the name pla-te mov-ed along the base to show a magnet locking pin captive in the base.

Figure 14 is a partial vertical section of a multiple name plate assembly employing a magnet and a gang dowel ~or lock-ing the name plates.
Figure 15 is a front view of the multiple dowel shown in Figure 14.
Figure 16 is a side view of the multiple dowel shown in Figure 15, Referring to the drawings and particularly to ~igures 1 to 4, Figure 1 is a partial perspective view of one end of a name plate assembly 5 of typical form which includes a base 6 and a name plate 7. The base 6 is preferably of extruded form having on its front face 8 a pair of dovetailed rails 9 and corresponding but smaller dovetail-shaped recesses 10 on its rear face 11. The name plate 7 has a flat front face 12 and on its rear face 13 there is provided a pair of dovetail-shaped recesses 14 adapted to fit on the rails 9 of the base 6 for sliding movement o-P the name plate 7 on the base 6.
At a distance inwards from one end of the base 6 there is drilled, or otherwise formed, a vertically disposed cavity 15 centrally disposed between the front face and the rear face of the base 6, the cavity 15 extending upwards behind the rail 9a and downwards to be exposed in the dovetail recess 10 located between the two rails 9.
The name plate 7, a* the same distance inwards from the end of the name plate as the cavity 15 in the base 6, has a cavity 17 drilled, or otherwise formed, extending downwards from the low-er edge 14a of the upper recess 14.
A floating magnet 18 is located in the cavity 15 in the base 6 and is held therein by the plug 19 set in the rear face of the base 6, as shown in Figures 3 and 4. The plug 19 is held in place by the detents 20.

The cavity 15 in the base 6 and the cavity 17 in the name plate 7 are aligned with each other when the name plate 7 is Z~

a ligned in its correct position on the base 6 and when the hase and name plate assembly are positioned vertically when mounted on a door or in a directory stand, as shown in Figure 2, the lower end o~ the magnet 18 drops into the cavity 17 in the name plate 7 to lock the name plate f'rom horizontal movement relative to the base 6, An external magnet A, shown in Figure 4, is applied to the top edge of the name plate assembly f'or the purpose o~ lifting the rod magnet 18 out o~ engagement with the cavity 17 in the name plate 7 and thus releases the name plate ~rom locking engagement with the base member.
In Figure 5 there is shown an arrangement of two magnets 19 and 20 located parallel with each other in the base member 69 with the magnets having opposite polarity requiring an opposite pole magnet to retract the magnets 19 and 20 ~rom locking engage-ment with the name plate.
In Figure 5a the magnets l9a and 20a are similar to those shown in Figure 5. In order to permit the magnets l9a and 20a to lock with a name plate when the assembly is mounted on a flat ho-rizontal surface, an additional magnet 21 is mounted in a f`ixedposition at right angles and spaced f'rom the inward ends of the magnets l9a and 20a, In this arrangement the magnet 21 pulls the magnets l9a and 20a into locking engagement with the name plate.
In Figure 6 there is shown an arrangement of' two magnets 22 and 23 which are ~ertically aligned with each other, one in each of' the rails 9. These magnets 22 and 23 are of' opposite po-larity and their adjacent ends 24 together act to lock the name plate to the base in the manner abo~e described, In Figures 7, 8, 9 and 10 there is shown a variation in which the round-f'lat magnets are used to lock the name plate to the base on which the name plate is mounted.

In Figures 7 and 8 the magnet 25 is mounted centrally on ~ 3~

the leaf spring 26 and the magnet is seated within the aperture 27 in the rail 9a. The leaf spring 26 has its ends anchored at 28 in the longitudinal recess lOa in the rear face of the base member 29, The name plate 30 has a circular recess 31 ~ormed in its rear face 32 in which the magnet 25 is normally seated when the name plate 30 is positioned on the base member 29, and is withdrawn from its seated position when the operative magnet is applied to permit the name plate to be slidingly removed ~rom the base member.
Figures 9 and lO are similar to Figures 7 and 8, except that two magnets 33 are employed, secured to the ends o-f the lea~
spring 34 which is secured centrally to the rear face Oe the base member 35. The magnets 33 seat in the recesses 36 in the name plate 37 to hold the name plate locked on the base member 35.
In Figures 11, 12 and 13 there is shown an arrangement similar to Figures 7, 8 and 9 with the exception that round rod type~magnets 38 and 38a are secured on the ends of the single leaf spring 39 and the double leaf spring 40O
In Figures 14, 15 and 16 there is shown a still eurther modieication in which a series o~ name plates 41 are mounted on a board, such as a directory board 420 The means -eOr locking the name plates 41 on the board is shown in Figures 15 and 16 and con-sists o~ a gang rod 43 having raised portions 44 which ride in slots 45 within the rails 46 mating with corresponding slots 47.
A magnet or soft iron plate 4~ in the name plates is secured to the top end of the gang rod 430 When the operative magnet is applied close to the loca-tion o e the magnet 48, the magnet or so~t iron plate ~8 is attrac-ted to move upwards in the mating slots 45 and 47 and thereby with-draw the raised sur:eaces 44 o e the gang rod 43 upwards out o~ en-gagement with the slots 47 in the lower edge portion o e the name platesO

In all of the above described arrangements, the metal dowels or magnets locking the name plates to the base member on which they are mounted can only be moved out of engagement with the name plates by the application of the operative magnet, shown as an external magnet and designated ~ in Figure 4, to the name plate assembly adjacent to where the locking magnet is located.
For instance, the pin-type metal dowels or magnets 18 such as are shown in Figure 3 would require the external magnet A to be applied to the top horizontal edge of' the name plate assembly, and where the disc-type magnets are employed, the external magnet A would have to be applied to the outer face of the name plate in order to repulse the disc magnet out of engagement with the name plate.
In other arrangements such as where two magnets are used as in Figures 5 and 5a, a double-pole external magnet is employed to attract the two magnets away from each other to unlock the name plate from the base member.
Where an electrical supply is available, the external magnet A shown in Figure 4 can be replaced by electro-magnets built into the base member and controlled by switches or push buttons which in turn can be locked against unauthorized use.
While the base members and name plates have been illus-trated having dovetailed mating surfaces, the base members couldbe of channel form, having lips at their longitudinal edges to retain the name plates for sliding movement in the channels.
With the above described arrangements the name plates cannot be removed from their mounting and no visible locking ar-rangement can be seen. One must have the knowledge that an exter-nal magnet must be used to unlock the name plate and, in certain instances such as with the arrangements shown in Figures 5, 5a and 6, the external magnet must be used in a specific way in order that the locking magnets will withdraw from locking contact with the name plateO
