Abstract
Abstract of the Disclosure An illuminated sign assembly has a cabinet of somewhat resilient sheet material with a self-hinging sign frame on at least one side which snap fits into the cabinet without use of a conventional hinge. An assembly may be provided for security and tensioning the vinyl sheet of a sign face into the frame. The snap action is provided by interaction between a channel defined by a system of resilient flanges formed by a portion of the cabinet to which the frame is hinged, and an abutment on a rearwardly extending flange on a hinged side of the frame.
Description
The present invention relates to an illuminated sign assembly.
The cabinet or casing for illuminated siqns has traditionally been oF box-like configuration formed by aluminum extrusions, and is generally arranged so that the assembly is weatherproof for outside use.
The cabinet has either one open face, ~or mounting a single-faced illuminated sign, or opposed open faces for mounting double-faced illuminated signs.
However, the use o-E aluminum extrusion for the cabinet has two disadvantages.
First, the aluminum is a rigid material, and if the sign frame is to be hingeable outwardly to open the cabinet for maintenancei some leeway must be provided where the sign frame hooks on~o the top of the cabinet. Any such leeway will prevent a snug fit when the sign frame is closed against the cabinet, allowing the sign to rattle, with consequent potential damage, in heavy winds.
Also, different widths of extr~sion require separate extrusion moulds at a substantial cost per mould. Because of this cost, a relatively small variety of standard widths of aluminum extrusion are available for manufacturing illuminated sign cabinets. In addition, there is a physical limit on the width of aluminum extrusion which can be extruded of 12 to 14 inches. For illuminated sign assemblies with deeper cabinets, widths of extrusion must be fastened together, with consequent loss of weather-proofing.
The present invention is therefore directed to providing an illuminated sign assembly with a self-hinging sign frame which snap fits onto the cabinet and does not require a conventional hinge, and can also be assembled utili~ing concealed fasteners to provide a clean and uninterrupted visual appearance meeting architectural standards.
The cabinet for the iLluminated sign assembly in a first embodi~
ment of the present invention is formed of a somewhat resilient sheet material, such as sheet metal. One advantage achieved by using sheet metal is that the cabinets for such sign assemblies can be formed of almost any width or profile, and of many dif-ferent profiles to achieve various lighting and styling effects according to the user's requirements.
The invention is also directed to an improved assembly for secur-ing and tensioning the vinyl sheet of a sign face onto a brace for inclusion ln an illuminated sign assembly.
In one embodiment, an illuminated sign assembly is provided con-sisting of a cabinet for holding an illuminating device, formed of resilient sheet material and having side walls and an opening in one face. At least one side wall of the cabinet is provided with an inwardly directed flange adjacent the open face of the cabinet r a forwardly directed flange extending from the inwardly directed flange, and an outwardly directed flange extending from the forwardly directed flange and forming with the inwardly and forwardly directed flanges an outwardly opening channel. A
return flange extending rearwardly from the outwardly directed flange is also provided. A sign frame is provided for mounting adjacent the open face. The sign frame has a rearwardly directed lip provided with a laterally extending abutment. The sign frame snaps from an inclined position, in which the lip e~tends inward-ly into the channel, to a position parallel to the opening, in which the abutment and lip are compressed between the inwardly directed flange and the return flange.
~referably, the return flange of the cabinet is offset inwardly from the at least one side wall. When the sign frame is in the position parallel to the opening, the sign frame has an outer wall which is then also parallel to the opening. The lip of the sign frame is preferably offset inwardly Erom this o~1ter wall~
Means may also ~e provided for releaseably securing the sign frame to a wall of the cabinet opposite the at least one wall when the sign frame is in the position parallel to the opening.
In a separate e~bodi~ent o~ the invention, a vinyl retainer frame for an illuminated sign assemb~y is provided consisting of a rigid brace of substantially C-shaped configuration extending from one side of the frame to an opposite side; an internally serrated clip for receiving a longituclinal fold of one end of a vinyl sheet, a serrated retainer adapted to be received in the fold and the clip for snuyly positioning the longitudinal fold of vinyl in the clip, and means for attaching and tensioning the clip at one end of the brace, ~hile the sheet is secured at the opposite end of the brace. Preferably, a second c]ip ancl retainer are provided for attaching and tensioning a longitudinal fold of vinyl at the opposite end of the brace, in order to tension the vinyl sheet between the clips.
Preferred embodiments of the invention will now be described~ by way of example, in association with the accompanying drawings, in which:
Figure 1 is a perspective view of an illuminated sign assembly according to the invention showing the sign frame in closed position and F in phantom outline, showing the sign frame in hinged-open position;
Figure 2 is a cross-sectional view of a portion of the assembly of Figure 1, taken along line 2-2, showiny the assembly in closed position;
Figures 3 and 4, on the same page as Figure 1, are fragmentary cross-sectional views of the snap-fit and hinge structure, showing the assembly in closed and open positions, respectively;
Figure 5 is a cross-sectional view of the vinyl-retaining assembly, accordiny to the invention;
Figures 6 and 7 are fragmentary cross-sectional views showing the vinyl retaining assembly mollnted on a cabinet in closed and open positions, respectively; and Figure 8 is a f~agmentary cross-section through the upper por~ion of an alternative ernbodiment cf sign assembly, illustrating alternative cabinet confiyurations.
In Figure 1, an illuminated sign assembly is illustrated consisting of a cabinet 1 on which is mounted a sign frame 2.
~he ca~inet is p~ovided with opposed side walls 3, top wall 4 and bottom wall 5. ~he front face is left open and the back may be eithe-r enclosed, for a single faced illuminated sign, or left open as well for a double faced illuminated sign.
Whilst preferably ~he cabinet is formed of bent sheet metal, or of some other suitable sheet material which is strong, sufficiently weatherproof and somewhat resilient, the use of other fabrication techniques such as extrusion or roll forming is not excluded.
Each wall of the cabinet terminates in a peripheral, outwardly opening channel 6 adjacent the open face of the cabinet 1.
If the cabinet is intended as a double-faced illuminated sign, a corresponding channel to channel 6 will also be formed adjacent an opposed open face.
Channel 6 is formed by inwardly directed flange 7, forming a resilient rear wall to the channel, forwardly directed flange 8 and outwardly directed flange 9. Although the cabinet is formed of resilient material, this arrangement of flanges serves to stiffen the structure of the cabinet while still allowing sufficient flexibility for the spring action which will be described below.
Outwardly directed flange 9 is bent inwardly to form shoulder 10 and inwardly directed flange 11, which may be hemmed~ as shown at 5~;4 11a, for rigidity and extra strength. Preferably lip 11 is offset inwardly from the cabinet wall 4.
In one embodiment illustrated in Figures 2 to 4, the sign frame 2 is formed of alu~inum extrusion lengths 19 of configuraton.
The sign face is formed of a rigid translucent plastic or acrylic sheet 21, which has a peripheral abutment 22, preferably formed of the same material as the sheet. Edges of the sheet 21 with abutment 22 may be inserted snugly along a channel 19a of a length of the aluminum extrusion 19, the abutment 21 acting to retain the sheet 21 in the extrusion channel 19a.
The ends of the lengths 19 may be mitred as seen in Figure 1, and internal L-shaped corner brackets 29a and 29b (see Figure 3) having opposite arms connected in channels 20a and 20b adjacent their ends, in conventional fashion, may serve to hold the lengths 19 together.
Each length of extrusi~n 19 is further formed with a rearwardly projecting right angle lip, generally designated by 23, which is preferably offset inwardly from the top of extrusion 19 to sit on lip 1 lo Metal screws 24, which are substantially shorter than the depth of channel 6, may be inserted through top lip 23a to provide an abutment engaging the edge of flange 11 at the same time that the opposite edge of top lip 23a compressingly engages rear wall 7, for a spring or snap fit to positively locate the sign frame 2 on the cabinet. These screws may be self-tapping, or aperture may be pre-formed in the flange.
It will be obvious to one skilled in the art that the abutment may be constituted by posts or other similar structures formed with the lip 23a.
Once the sign frame 2 is closed in place on cabinet 2, longer metal screws 25 may be inserted through bottom lip 23b, to pass - .
', .,: ` ~ . , ~ ,: , ''; , '` :
through wall 8a, ~o secure the sign frame 2 on the cabinet 1 (Fiyure 2). Again, self-tapping screws may be utilised, or apertures pre-formed to accommodate the screws.
Flange 26 extending at a right angle from lip 23 acts to channel water off the edges of the sign frame when the sign assembly is closed. Flange 26 also provides an aesthetically neater appearance to the sign assembly construction.
The outer surface of the extrusion l9 is extended rearwardly to form a flange 2~ outwa~d of the lip 23 which serves to hide fasteners such as screws 2~a utilized to secure the ~rac~ets 29a.
The flange 28 gives the sign assembly construction a finished appearance, to provide a clean architectural appea~ance. Flange 28 also functions to channel water, thereby improving the weatherability of the assembly~
As illustrated in ~igure 4, the sign frame may be hinged outward-ly to allow maintenance on the illuminating device inside the cabinet 1. When the sign frame 2 is tilted outwardly from the open face of cablnet 1, the end of top lip 23a will engage flange 7 in order to provide support to tne forward portion of lip 23a hinging on flange 11 and the rear wall 27 of extrusion 19 hinging on shoulder 10. The abutment or screw 24 simultaneously engages the end of lip 11, and suspended s~lpport of the sign frame 2 in the hinged open position is achieved by compression of the screw 24 against the end of flange 11 and the end of flange 23a against the somewhat resilient surface of flange 7.
In this manner, sign frame 2 may be hinged on cabinet 1 without the necessity for any additional props or stops.
In Figure 5, a second embodiment for the sign frame 2 is illustrated. In this case, the sign itself is formed of a flexible material such as vinyl.
The main component of the sign frame is generally a C-shaped brace 30 which is Eormed of two brace brackets 31 connected to intermediate rigicl column 32 by bolts 33. The brace brackets 31 are thus usable to connect to an intermediate column 32 of any length, and the sign can thus be easily modified by size.
Braces 30 may be placed at approximately four to five feet intervals along the length of a sign to provide ade~uate support for the structure.
Each brace bracket 31 is inserte~ into a frame 34 provided with blunt end 35 over which vinyl 36 passes. Frame 34 is a continuous frame, assembled at mitered corners, to provide a four-sided structure. L-shaped corner brackets may be inserted into channel 46a to secure the corners of frame 34r Along the top and bottom edges, a longitudinal fold is formed in the vinyl 36, and each fold inserted into a clip 37 provided with internal serrations. Each clip 37 is approximately three inches in length, and it has been found most advantageous to place a clip 37 approximately every ten inches around the perimeter of frame 34.
A serrated retainer 38, of the same length as the clip 37, is forced, in the middle of the fold, into the mouth of clip 37 to snugly secure the fold of vinyl in the clip 37.
The two clips 37 are affixed to opposed frames 34a and 34b with the vinyl sheet 36 at first slack between them~ Long bolts or screws 39, which are used to attach the clips 37 to the frame 34, may be adjusted to tension or loosen the vinyl sheet 36 held between them. As tension is applied to the sheet 36, it pulls the serrated retainer 38 and the folded edge portion of the vinyl against the clip thus providing a secure fastening.
Cover 40 is a continuous length of extrusion attached over the frame 34 around its perimeter by bolts 41, in order to protect the internal sign assembly from the weather.
A].ternatively, cover 40a~ having a right-angle f].ange 42 -traming all or a portion of the perimeter o the face of the sign, may be substitute-l.
As illustrated in Figures 6 and 7l it is intended that the vinyl sign frame be mountable and self-hingeable on the cabinet 1 in the same manner as previously described.
An overhang 43 may also be provided, extending rearwardly from cover 40/ providing aesthetic finish and water channelling as described above in relati.on to overhand 26 illustrated in Figu~es
