- SHEET 2 OF 2 FIG 5 1 SIGN BOX wrrn CLOSURE This invention relates to an illuminated sign and more particularly to a box for an illuminated sign of a type wherein a hinged front panel supports a translucent member having characters delineated by contrasting colours or by opaque areas which is back lighted by incandescent or fluorescent light. This application is a continuation-in-part of application Ser; No. 285,206, filed Aug. 31, 1972, now abandoned. v
BACKGROUND OF THE lNVENTlON that it is vibration free as the wind applies a force or pressure against this translucent member.
Usually, a one-sided sign is attached to a building an a two-sided sign is suspended from'the top or supported from the bottom. With the one-sided sign, the front panel must be removed to gain access to the interior of the main frame, to attach the main frame to the building. When the main frame is secured, the front panel must be replaced onthe main frame and secured properly to prevent the front panel from coming off the erably holds the translucent member in such a manner main frame, and possibly injuring someone beneath the sign. The front panel is supported in such a manner that the front panel does not have to be completely removed when some maintenance work has to be done on the sign at the site. Also, the sign is constructed insuch a manner than if any repair work has to be done on the sign, it'usually can be done without havingto take the sign down and return it to the shop for repair.
Preferably, the sign'is so constructed, that it can easily be disassembled and the repair work done to it on the site. Preferably the translucent member is made of plastic or the like and has attached thereto character or symbol forming members which have transparent, translucent or even vacant area. The members alsomay be partially opaque. The plastic translucent member usually expands and contracts as it is outside, open to the elements.
The known sign mentioned above has a suspension or support means for the front-panel on the top member of the main frame only which does not prevent the twisting of the front panel on the main frame under'the effect of high winds. To remove the front panel from the main frame, it is necessary to move the bottom of the front panel upwards and outwards from the main from until the front panel is approximately perpendicular to the main frame. The manoeuvre is very difficult when the operator is standing on a ladder approximately 10 feet above the ground. If, by some uncommon act, such as high 'winds, the suspension means are detached, the front panel is apt to come off the main frame and as there is no other securing means thereon, it will fall to the ground.

candescent or fluorescent illuminating elements 13 are arranged within the main frame 11 as will be described hereinafter. The illuminating elements 13 provide the back 'lilght for one translucent element 14 in a one sided sign and two translucent elements 14 in a twosided sign.
The main frame 11- is preferably rectangular in shape being formed of'aluminum extrusions having atop and bottom members 15 and 16 respectively, joined, to-
gether at the ends by side members 17 and 18 (shown in dotted lines in-FIG. 4) respectively. The members 15' to 18 preferably have identicalcross-sections. The cor-' ners of the members are mitred and a gusset 19(shown in FIG. 4) and screws (not shown) are used at each of the corners to connect the top and bottom members 15 and 16 to the side'rnembers 17 and 18 as will be described hereinafter. The main frame 11 for a one-sided sign is shown in FIG. 2 with the front panel 12 associated with the main frame 11 onone side with a suspension or support means 20 and a wall support member 21 at the other end. A groove 22 extends around the circumference of the main frame 11 and is U-shaped,
having parallel side walls Band 24. Extending out-.
wards from the side wall- 23 of the main frame 11 is the support means 20 comprising a shoulder 25, a concave supporting wall 26' extending downwards from the shoulder and outwards past the free end of the shoulder 25 having a free end 27. A J-shaped member 28 is connected to the supporting wall 26 adjacent the free end I 27 thereof. The'shoulder 25 has an upper surface 29 in the same plane'as the outer surface of the top member 15. A plurality of threaded holes 30 are tapped through the shoulder 25. The holes 30'are spaced apart on the top member 15 and bottom member 16 only and are the front panel 12. is placedon the main frame 10. A C-shaped engaging means 44 is positioned at the junction of the side wall 36 and retaining flange 39. The C- shaped member 44 rests on the free end 27 of the supportingwall 26 when the front panel 12 is placed on the main frame 11. The sickle-shaped member 43 has an outer surface 45 which makes contact with the supporting wall 26. Thesickle-shaped member is of such a width, that without screws 31 passing through the holes 30, the sickle-shaped member 43 can be drawn out of contact with the supporting wall 26 without tilting the fron panel l2.Also, the sickle-shaped member 43 has I such a length that the outer surface 45 engages the supadapted to receive preferably a flat headed threaded screw 31 therein. A The front panel 12 is rectangular in shape and made from aluminum extrusions having spaced apart top and bottom members 32 and 33 respectively joined at their ends by side members 34 (only one is shown). The corners of the members are mitred and joined together by gussets and screws (not shown). The members of the front panel l2 are U-shaped channels with parallel side walls 35 and 36 joined at one end by a base 37. The side wall 35 has a length greater than theside wall 36 for reasons which will be explained hereinaftenAt the free ends of the side walls 35 and 36 are inwardly extending flanges 38 and 39 respectively forming a slot 40 between them to receive the translucent element 14. Ex-
1 tending inwardly from the side wall 35 at the junction I I wall 36 and extends perpendicularly therefrom to engage the concave wall 26 of the support means 20 when porting wall 26 when the C-shaped member 44 rests on the free end 27 of the wall 26. When the front panel 12. is placed in the position shown in FIG. 2, an opening 46 is left between the top member 32 of the panel 11 and the shoulder 25 on the main frame 11. The translucent element 14 supported in .the front panel 12 is preferably rectangular in shape having strips 47 adhesively bonded to the top and bottom edges of the element 14 for assembly as will be described hereinafter.
As shown in FIG. 2, the members of the main frame I 11 have an inwardly extending Z-shaped member 49; attached to the side wall 24 of the groove 22. The Z- shaped member 49 has parallel walls 50, 51 and 52 joined by a perpendicular wall 53. At the other side of the member of the main frame 11 is a T-shaped member 54 having .a stem 55 attached to the underside of the top member 15 and a bar 56 attached on the stem 55. A diverging wall 57 is connected to the bar 56 to receive a clip means 58 attached to the wall support member 21. The stem 55 of the T-shaped 'member54 is spaced apart from the side wall 24 of the groove 22 the width of the gusset member 19.,The bar 56 of the T-shaped member and the wall 50 of the Z-shaped member 49 are spaced from the underside of the top member 15 a distance approximately equal to the thickness of the gusset 19. Also the wall 51 is spaced apart from the wall 52 of the Z-shapedrnember the thickness of the gu et member 19. f i
The structure of the top member 15 for the main frame 1'1.on a two-sided sign is shown in FIG. 3. The support means 20 extending outwards from .both side edges of the top member 15 are identical to the support means 20 described in FIG. 2. Extending inwards from the side wall 24 on both sides of the main frame are Z- shaped members 49 having parallel walls 50 and 52 joined by the perpendicular wall 53. The wall 52 has a free end 59 diverging therefrom. Between the free ends 63 on opposite sides is clip-in bar 60 (shown in dotted lines). The clip-in bar 64 has arrow heads61 adjacent its ends with the free ends 59 to provide'a spacing between the bar 60 and the underside of the top member 15 to receive the'wires and fixtures and fluorescent ballasts (not shown) required for the illuminating elements 13.
' As shown in FIG. 4, the gusset 19 is a right-angle shaped member having two legs 63 and 64 of approximately equal lengths joined together at a junction 65. The inner surfaces of the legs 63 and 64 have a plurality oftransverseteeth cut therein with diverging walls 66 joined at their ends by straight walls 67.
I The use and assembly of the sign according to the invention is as follows:
The members 15 to 18 of the main frame 11 are cut to size and the corners mitred. The main frame 11 isthen assembled using the gussets 19 at each corner to inner surface of the gusset 19 to prevent the members from coming apart at the corners, thus providing a weathertight seal at the corners of the main frame 11. With the one sided sign, the clip means 58 of the wall support member 21 is inserted between the bar- 56 and the diverging wall 57. Screws (not shown) are inserted in threaded holes (not shown) in the diverging wall 57, clip means 58, and bar 56 to connect the wall support member 21' to the main frame 11.
The members 32 to 34 of the front panel 12 are cut to size and the corners mitred. The translucent element 14 with the strips 47 at the top and bottom edges is then assembled with the top and bottom members 32 and 33. Gussets (not shown) are then inserted in the ends of the side members 43 and'the side members 34 areass embled with the top and bottom members 32 and 33 by passing the free ends of the gussets (not shown) into the ends of the top and bottom members 32 and 33. Screws (not shown) are then passed through side walls 35 and 36 of the members to make contact with the gussets to prevent the members from coming apart at the corners thus providing a weathertight seal at the, corners of the front panel 12.
The front panel 12 is then assembled with the main frame 11 by placing the sickle-shaped member 43 in engagement with the concave supporting wall 26 of the support means 20. Also the C-shaped engaging means 44 on the front panel 12 engages the free end 27 of the concave supporting wall 26. Stop means on screws 31 are preferably secured to the shoulder 25 of the support means 20 of the top and bottom members 15 and 16 ofthe main frame 11 in such a manner that the screws 31 are not in engagement with the sickle-shaped member 43 but prevent the sickle-shaped member 43 from coming out of engagement with said concave supporting wall 26. r
To tilt the front panel 12 upwards and outwards relative to the main frame 12, the screws 31 on the bottom member 16 of the main frame 11 are removed to permit the bottom member 33 of the front panel 12 to be drawn out of engagement with the bottom member 16 of the main framell. As the front panel 12 is moved upwards and outwards the sickle-shaped member 43 engaging the concave supporting wall 26 on the top member 15 of the main frame 11 is rotated. The screws 31 prevent the front panel 12 from coming away from the main frame 11. A standard (not shown) may be inserted between the bottom member 33 of the front panel 12 and the bottom member 16 of the main frame bottom members 15 and 16 by gussets 19. The free end of the gussets 19 is inserted between the walls 51 and 52 of the Z-shaped member 49 and screws (not shown) are passed through the wall 52 tosecure the gusset 19 therein.
In the front panel 12', the translucent member 14 is held securely between the retaining flanges 38 and 39 of all themembers 32 to 34. The slot 40 between the retaining flanges 38 and 39 preferably has a width free end of. the flange 38 engage the outer surface 43 sealed all around the frame on all four sides thereby enin channel 73 and will not permit rain and the like from- 11 to hold the front panel 12 at the desired position relative to the main frame 11. This permits a worker to work on the interior of the sign 10 without having to remove the front panel 12 from-the main frame 11.
It should be noted that if a one-sided sign 10 is constructed which has a much greater length than height, supports or stiffners (not shown) are necessary between the top and bottom members 15 and 16 of the main frame 11 at different locations along the length of the main frame. The stiffner is placed against the wall supporting member 21 and is attached to the top and when the strips 47 engage the flange 39 of the top and bottom members 32 and 33.
With further reference to' the drawings. FIG. 5 is a sectional view of an alternate embodiment of the inven-- tion showing in section a sign frame with a front detachable panel attached thereto similar to the frame and panel of FIG, 4. According to this further embodiment of the invention, the groove 46 can be replaced by a pair of grooves shown on the new FIG. 5 as and 74 with a flange 72 therebetween. When the panel of the frame of FIG. 4 is positioned in the open, dirt, snow, ice, and water may fall into the groove sections at the top and run down to lodge between the movable sickle section and its curved mating part causing the parts to bind when an attempt is made to open the front panel for service. In order' to seal the hinge an angled channel 73 is-provided with a plastic sealing strip 730, and a sealing rib 72a is formed onflange 72 to engage the strip 73a. ln this way the groove 74 is completely suring that the interior of the device is kept clean and dry at all times and in addition the moving parts are thereby more easily hinged one with another when the sign is lifted for service.
In the embodiment shown in FIG. 5, ll designates the main frame. Numeral 15 is a top section of the main frame having the curved section 26 attached to it and having the attachment means 31 positioned in a recessed support 23. Along the edge of support 23, channel 73 is attached for carrying the sealing strip 73a. The bolt support 23 at the bottom of groove 74 is drilled and threaded to receive bolts 31 therethrough. An additional groove 70 is formed by an upwardly turned support member 71 having flange 72, forming a groove 70 between the flange 72 and the front panel frame 37. Sealing rib 72a extends below flange 72 and registers with channel 73 positioned below the groove formed by the channel section 71 and 72. In this way, the panel I may swing and hinge freely about the main frame and yet in a resting position, rib 72 seals with seal strip 73a entering into the area above the mating hinge and sickle members and similarly will seal the other three sides of the flange.
The supporting wall 26 with its free end and J-shaped member 28 has been re-designed in the embodiment shown in H6. 5 by having the curved wall 26 project in a horizontal direction, then inwardly curved as at 76 to form a lip member which contacts the movable projection means 44 of the front panel to provide a surface contacting pair of curved members 44 and 76 which replace the point contacting members formerly shown as 44 and 28 in FIG. 4 allowing for a greater load bearing contact of the front panel against the main frame when the front panel is in the vertical rest position.
, 7 As indicated previously, the front support 26 bears the weight of the front panel 37 through the surface contact of the front support 26 which the sickle-shaped hingeable member 43, such that the screw member 31 does not bear against the surface of the sickle member or against its edge unless a force is applied, such as the force of a wind or a jarring movement against the front panel designed to push it out of contact with the main frame. Then the screw 31 will hold the panel in its rest position against the curved support 26. The sickleshaped hingemember 43 has a flat surface shank portion 77 attached and integrally formed with the side wall 36 of the front panel allowing for greater surface contact with the support wall of the main frame since rain and weather is prevented from entering into the area above the sickle-shaped. member and from interfering with the free smooth operation of the hinging of the'sickle-shaped member 43 on the curved surface 26 it is found that agreater surface contact between the parts can be permitted thereby allowing for a more stable position of rest forthe front panel section on the main frame and allowing for a greater weight to be transferred to the main frame and thereby allowing the main frame atthe curved support, to carry a greater weight.
ln'operation the assembly of the sign box is essentially the same as in the case of the embodiments of the FIGS. 1 to 4. The hinge is formed by merely placing the front panel in position against the mainframe, with the sickle-shaped member 43 lying on the curved surface 26 around all four sides of the frame. The screws 31 are then inserted into the threaded holes in the shoulder 23,.along the top portion of the frame 15, and are screweddown into position until'they bid against the sickle-shaped member 43.
Similar screws 31 are then inserted in similar holes in the bottom portion 16 of the frame.
The front panel'of the sign box is in this manner secured to the main frame, and the contact between the sickle-shaped member 43 and the curved portion 26 of the support member effectively seals and secures the front panel against any tendancy to shake or rattle or become loosened by wind action. In addition, any possibility for drivingrain or moisture to enter the interior of the sign isprevented by the effective seal provided by the plastic sealing strip 73a, and the ribs 72a bedding into the plastic strip all around all four sides of the sign.
When it is desired to service the interior of the sign then the bottom screws 31 are removed and the top screws 31 are backed off two or three turns, at which point the front panel may then be swung upwardly.
By re-designing the contacting surfaces of the'front panel and the main frame support, there is less liability of breakage and rupture of the parts when in rest contact position when high winds batter against the sign and jar the contacting surfaces together. In the result, the contacting surfaces can be made of less rugged construction giving a saving in material and manufacturing costs.
The foregoing is a description of a preferred embodiment of the invention only. The invention is not to be taken as limited to any of the specific features described, but comprehends all such variations as come within the spirit and scope of the claims.
