~, DISPLAY APPARATUS
d of the Inventlon The present invention relates to a display apparatus, and particularly to means for mounting siyns to walls and ceilings or other surfaces.
Summar of the Invention According to the invention there is provided a display apparatus comprising at least one elonge display member which is adapted to bear indicia for display, and at least one support for the display member. The display member is an extrusion of C-section, defining a channel, the extrusion having wall portions at one side defining between them a narrowed mouth of the channel, and an opposed base portion. The extrusion also has an opposed pair of internal ribs that extend parallel to the base wall portion and divide the channel interior into two longitudinally extending cavities, each of which has an open mouth at each end of the display member, and a first one of which communicates with the narrowed mouth while the second one of which is bounded by the base wall portion. A support includes a mounting portion having first and second arm portions disposed in an L-configuration and arranged to be mountable to a surface, and at least one display member supporting means projecting away from the first arm portion.
The display member supporting means and each of the cavlties is mutually dimensioned so that the supporting means is R

-la insertable in the longitudinal direction of the display member selectively into either cavity through either mouth thereof to provide support for the display member. The spacing of the supporting means from the second arm portion is such that the display member is supportable by the supporting means selectively in either of two con-figurations, namely in either a first configuration in which the base wall portion is substantially in contact with the second arm portion and the supporting means is inserted in the cavity bounded by the base wall portion, or a second configuration in which the second arm portion is substantially in contact with the narrowed mouth defining wall portions, and the supporting means is inserted in the cavity which communicates the narrowed mouth~
Preferably the support is selectively mountable in two configurations such that the projection means extends outwardly away from or substantially parallel to the surface.
A display apparatus may then include two supports, mountable with their projection means mutually opposed and arranged to be received within the display member extrusion.
The or each support may be an elongate element having a multiplicity of projection means along its length, whereby a multiplicity of display members are supportable.
Pre~erably the projection means are so spaced that display members are mountable with adjacent display members .,;. . ~

substant:ially in eorltact so as to preC;ent a s~lbst:anticlLly flush composite surface. ~n elongate element may be arrangecl to be separable into desired lengths containing any number of projection mearls. Display members may be of different sizes, having channels receiving one or a plurality of adjacellt projection means.
A display member may have means defining two like parallel channels, each extending over its whole length and open at both ends, so ~hat either can receive a projection means. Preferably at least one of the channels is open along at least part of its length, so that a slat may be slidably received in it with a portion of a surface of the slat visible through the opening. Depending on which channel receives the projection means, this open channel may face in either direction. A channel may have means defining elongate ribs projecting into it, so as to define two substantially parallel narrower channels, one behind the other. This is par~icularly useful for a forwardly-open channel. For example, the rear one of the narrower channels may contain a slat bearing alternative information such as "IN" ancl "OUT", and the front narrower channel may contain a short slat which is displaceable so as to o~scure selectively one of these. The projection means may have grooves for receiving the elongate ribs defining the narrower chan~c-ls. This may increase the positiveness of the support.

Description of the Preferred Æmbodiment The support 10 comprises a generally L-shaped elongate bracket 12. The shorter leg of the L has, at its free end, an upstanding flange 14 projecting in the same sense as the other leg. At an intermediate region of the shorter leg, close to the longer one, there are a multiplicity of tongues 16 projecting generally parallel to lS the longer leg. The tongues 16 are arranged in a row, with alternately large and small spacings between -them. For most of the length of a tongue 16, its cross-section is generally rectangular (possibly with bevelled edges), and with a slot 17 in that face which faces the nearer adjacent tongue 16. A free end portion 18 narrows to facilitate insertion of the tongue into a channel, as will be described later.
Between adjacent tongues 16 with the larger spacing, there are respective L~shaped channels 20 in the bracket 12.
That is, the thickness of the bracket 12 is reduced. The channels 20 have bevelled edges 22. The bottom of the channels 20 in the longer legs of the bracket 12 are . .

The support 10 is provided with regularly-spaced transverse lines oE weakness 28. These extend betwcen adjacent closely-spaced tongues 16. Preferably, the lines extend on the inside face of the flange 14 (facing towards the tongues 16), so that it is not generally visible.
It is preferred to form the support from plastics material, and preferably the main forming step is performed by injection moulding. It is convenient simultaneously to form a pair of spacer members 30, whose function will be described later. Thus, the moulding can give a support 10 with the spacers 30 attached by slender nibs 32, so that they can be easily detached on site.
Fig. 4 shows three elongate clisplay members 40,42,44.
~ach is an extrusion of constant section, having a base 46 and a pair of opposed arm pieces 48. Each arm piece 48 has an inwardly projecting flange 50 extending parallel to the base 46 from the middle of the piece 48. The outer end of each piece 48 has an inwardly pointing bevelled flange 52, which is of si.milar extent to the intermediate flange 50.
Between these two large flanges 50,52, there is a thinner and shorter flange 59.
Each display member is dimensioned so that it can . .

The next larges-t member 42 is of twice the si~e, and the largest 44 is of three times the size. (Of course, still larger display members could be used.) In each case, the arm pieces 48 extend between closely-spaced tongues 16. It can be seen that the dimensions are such that when there are a pair of display members 4~ occupying adjacent sites, their adjacent arm pieces 48 are i.n contact.
A display member can be fi-tted to the support 10 so that tongues 16 thereof engage either between the intermediate flange 50 and the base 46, or between the two lS flanges 50,52. This will affect whether it is the base 46 or the outer flange 52 which lies against the l.ong leg of the L-bracket 12. When the tongues 16 are engaged between : the flanges 50,52, then the small flanges 5~ engage in the slots 17 on respective tongues 16.
The illustrated apparatus may be used to mount a sign flat against a wal.l or other surface, or so as to pro~ect. For mounting flat against a surface, the support is fixed to the walls by screws or bolts passing through the apertures 24 (whose bevelled edges 22 provide counter-sinking). Generally, a pair of supports 10 will be used, one to support each end of the display members. They will.
then be mounted the appropriate distance apart, with -their , ' .'. ' ' ' ." ` . ' '1'. , '~' :. .

Thus one or both supports 10 can be slid outwardly to allow a display member to be engaged over tongues 16 of one support 10. Relative displacement of the supports 10 towards one another then drives the tongues 16 of the other support into the display members, which are thus securely and firmly held.
To provide a projecting sign, a support is mounted by screws or other such means driven through the panels 26, or through apertures provided by knoc~ing out these panels.
A display member can then be simply pushed over outwardly projecting tongues 16.
In either configuration, the display members can be mounted in two different orientations. It is normally desired to use the channel defined by the flanges 50 and 52 for mounting matter to be displayed, so of course one would not normally choose an arrangement in whic~ this was pointing into the wall. Generally, information to be displayed will be provided on slats which can be inserted slidably into the channels defined by the flanges 50 and 52.
Thin slats may be used which can be inserted into the narrower channels formed on ei.ther side of ~the small flanges 54. A slat beari.ng information could be mounted in the channel defined by flanges 50 and 54, whereas the front channel containecl a transparent protector shee-t.
Alternatively, the front channel may contain a short opaque , ~261~33~
slat which is sliclable so as seLectively to obscure parts oE the material written on the slat behind.
A pair of supports 10 may be mounted back~to-back, with corresponding legs of their L-brackets 12 abutting.
They may be cl~mped together by means of the spacers 30 passed through the apertures 24 (or apertures produced in the panels 26).
The illustrated support has kwelve tongues 16, though of course they can be produced with any number. If a small support 10 is required, e.g. to mount a single small display member 40, this is readily obtained by breaking off the required piece along a line of weakening 28.
In use, when a support 10 is used for supporting display members extending parallel to a wall, the only part of the support 10 which is visible from the front is the flange 14. This has a pleasing, unbroken appearance, since even any remaining lines of weakness 28 do not appear on this face. Of course, if the rear face of the shorter leg of the L-bracket 12 is visible, lines 28 are vislble thereon. However, these are not very unsightly, and are in any case invisible if pairs of supports 10 are mounted back-to-back.
The display members preferably comprise aluminium extrusions.
