Description
5~3 FIELD OF THE INVENTION
The present invention pertains to the combination of a connector element with a cover element which, once assembled, form part of a display panel which may be found in electric power distribution systems and serve to represent large distribution circuits and controls forming part of such systems.
BACKGROUND OF THE INVENTION
One example of such a diagram board or panel 10is found described in Canadian patent no. 1 126 023 datec June 22, lg~2 and entitled "Mosaic displa~
par;el". A series of inter-connected horizontal and vertical members supI)ort an assemb;y of tiles and con~roi instrumer;ts thrcugh interfiLting components.
15In the above-referreà Canadian ~atent, there ~s shown the cor;ne~ticn of a cover element with a conllector element where .he connecting parts of these elernents extend in the ~lane of the sidewGll cf the eiementC. Tc assem~le two adjacently disposed connector and~'or cover eiements, a spring act.on 'LS required.
OBJECTS AND STATEME;~T OF THE INVENTIO~
The present invention is concerned wlth imp~oving the inter-connec~ion of the cover eiement, or tile, of a display panel to the connector el~ment which, itself, is mounted to various other structural cornponents of the panel.
It is an ob~ect cf the pLesent invent:ion to ~,:
. r~
~25~3 transpose the spring action of -the inter-connection into the abutting planes of the cover and the connector elements thereby minimizing interference with other essential components of the panel and maximi~ing the usuable area for insertlon of those actuating or controlling elements which are usually mounted in a mosaic display panel.
The pxesent invention therefore relates, in "
its broadest aspect, to the combination of a connector 10 element and of a cover element wherein inter-engaging male and female means are prodided on opposing faces of these two elements, the inter-engaging means being slightly inclined with respect to a vertical axis. The male means are so disposed as to bear against an 15 opposing one of the faces prior to engagement of the cover element with the connector element. These elements are formed of elastic material so that pressure on the cover element causes deflection of the material in the area of the inter-engaging means to 20 enable a sliding insertion of the male means in the female means and to provide a tight frictional engage-.! ment between the cover and connector elements.
r In one form of the invention, the female means consists of cavities provided in the cover - 25 element and the male means consists of projections extending upward from the connec-tor element.
In an other embodiment of the invention, the ~2~25~3 projections are provided on the cover element while the cavities are provided in the connector element.
Yet, in an other embodiment of the invention, the completed insertion of the projections into the cavities is such as to leave an air circulation gap between the opposing faces of the cover element and the connector element. This also allows the insertion of a filter elem`ent which is used in the case where the cover element is made of a translucid material and the filter is colored thereby providing the tile with a particular shade when a lamp is mounted inside the connector beneath the cover.
~ he scope of applicability of the present invention will become apparent from the detailed description given hereinafter; it should be understood however that this description while lndicating prefer-red embodiments of the invention, is given by way of illustration only since various changes and modifica-tions within the spirit and scope of the invention will become apparent to those skilled in the art.

DESCRIPlllOIi OF PREFERRED EI~BOD~ENTS
Referring to figures 1 and ~, there is shown an in~er-engagelnent of a series of co~er elements, three of which are shown as 10, 11, 12, rnounted on a c~nnector element 14. These elements form some of the components used in che assembly of a mosaic display panel (not shown) where the top face of the cover eleinents, also called tiles, may disp,ay aiagrams or symbols, such as may be found on panels of elec,ric
2~ power dis~ribution systems. In some area of a panel, the cover elements are replaced by instruments such as lights, switches, knobs, etc.
The connector element 14 is mounted to various struc'urai members o~ the display panel and, ir.
the embodiment illustrate~, include a plurality of depending ieg~ 16, 18, 20 and 22 which are de~ined ir.
detail .n appliccnt's above-refelred pacent.
1%~5~3 -- s These legs extend from each sidewall o~ th~ connectol elemer.t, three of these sidewails ~eing identified as 24, 26, 28 where leg 16 depends from sidewall 24, legs 18 and 20 from sidewall 26 and leg 22 from sidewall 28.
In ~he embodimen~ illustrated, the connector element defines a rectangular body with fo~r opened spaces 30, 32, 34 and 36. However, a separate connector element may be formed of a single rectangular body with one central opened space similar, for example, to that which is shown in the lower right corner of Figure 1.
Silnilarly! a connector element may have a flat top face or one that is defined by the four pefipheral edges 38, 40, 42 and 44 as designated for the lower right quarter of the connector shown in Figure 1. Each corner of this quarter displays a projection 46, 4R, 50, 52.
Irl Figure 2 projection 48 is shown received in a correspondly ehaped cavity 54 provided in cover 10. This projection is in the form of a cylindrical body which extends upwardly with an inclination with respect to a vertical axis entending through the connecting elements. Similarly, cavity 54 has a cylindrical shape and extends upwardly with a similar inclination with respect to the vertical axis. The top wall of projection 48 has a chamfered section 58 .: .
5~3 to provide a centering effect during engagement as described hereinbelow.
Figure 3 illustrates the cover element resting on the projection 48 prior to engagement with S the connector element. The edges of the cavity at the level of the under face 56 define a funnel that includes a cylindrical portion 60 and a inward sloping portion 62 (see Figure 5). This particular funnel shape assists in centering the elements for the snapping engagement of the connector element with the cover elementO The location of the cylindrical bore 60 is such that when the cover element is placed on the connector element the edges of cavity 54 rest on the top face of projection 48.
The material of the connector element and of the cover element in the area of the inter-engaging male and female parts is elastic (poly carbonate, for example) so that, when pressure is applied to the cover element in the direction indicated by arrow 64 in figure 4j the result is a deflection of the mate-rial as indicated by arrows 66 and 68 which then allows a sliding insertion of the projection 48 into the cavity 54 to acheive the engagement illustrated in figure 5.
In figure 6, another embodiment of the invention is shown and consists in providing the height of projection 48 somewhat greater than the depth of a ~ .~
J
~2~ 3 cavity 54' so that once inter-engagement is completed, there is a gap 70 between the cover element 10' and the connector element 14. In some cases thls gap is requlred to provide air circulation between the connected parts especially when a heat dissipating instrument, such as a lamp, is mounted behind the cover in the connector element. In other cases, where a cover element 10' is made of a tr~nslucid material, a coloured filter element 72 may be mounted to rest on the top face of the connector element to give a particular shade to the tile when a lamp is mounted within the connector element.
Xeferring to figure 7, another embodimen-t of the present invention is illus-trated and consists of a cover element 76 provided with a construction similar to that of 10 and 10' with the exception that a pro-jection 78 extends from the under face 80 of the cover element into a cavity 84 provided in the top face of the connector element. In this embodiment, prior to engagement, the lower chamfered face 86 of the pro-jection rest on the edges 88 of the top face of theconnector element. Manual pressure on cover element 76 causes deflection in the material of projection 78 and that of the connector element in the area of the cavity to effect the snap engagement between the two elements. In this embodiment, a filter element 72' can also be mounted, if desired, in a manner similar ~2~ 9L3 to that illustrated in figure 6.
Although the invention has been described with reference to the specific forms, it may be refined and modifled in various ways. It is therefore wished to have it understood that the present invention is not limited in interpretation except by the ter~-ns of the following claims.
