Definitions

• This invention relates to an advertising sign where the desired message is applied to a relatively thin, flexible and, if desired, translucent canopy of reinforced or conventional plastic, fabric, or the like, which is stretched and fastened with a certain degree of tension onto a box-like structure in such manner that it remains completely straight and does not move substantially with wind pressure, etc.
• a box-like structure in such manner that it remains completely straight and does not move substantially with wind pressure, etc.
• sources of light in the form of fluorescent tubes, or the like, to enable the printed message to be visible in the dark also.
• the described advertising signs may frequently be several meters long; and it is thus clearly both difficult and strenuous to replace the fluorescent tubes, or the like, in these advertising signs because the entire length of the surface containing the message must be swung out and upward simultaneously, with the aid of hinges, etc. , and be held in the upward-swung position by, e.g., stakes while the replacement of the fluorescent tube takes place.
• Another disadvantage of the described structures is that the struts necessary to hold the fastening profiles for the canopy in the correct spaced relationship will cast shadows on the canopy even if said struts are made as narrow as possible.
• it is evident that in both production and use such advertising signs must be very demanding in terms of resources. Indeed, one can easily imagine how difficult it will be to open an advertising sign of a length of 10 meters to replace a fluorescent tube.
• the structure of the apparatus in accordance with the invention is much lighter and simpler, despite the fact that one attains at least an equal degree of a rigidity in the apparatus here, compared with the previous structures.
• the advantages that, firstly, it is very easy to mount the canopy correctly so that the message on the sign is not ruined by variations in height and in lateral direction. Considerable precision is required particularly when the message contains a straight line, which is often the case.
• the invention greatly facilitates the necessary tightening of the canopy to ensure that it does not move substantially even when exposed to the heaviest gusts of wind; and, in addition, it makes it possible to withstand much greater tolerances in the length and width of the canopy.
• the greatest advantage is attained when the light sources, e.g., in the form of fluorescent tubes, are to be replaced. Then, it is necessary merely to release the fastening device at the bottom and on the sides and to allow the canopy to hang straight down, because no heavy parts are attached to the canopy, and one then attains free access to the lighting tubes at the same time as the structure permits the resting of ladders directly against the structure at the top or the bottom. It is then a simple matter to reattach the canopy and to get it to hang exactly straight. All this may be accomplished by one person, regardless of the particular length of the advertising sign, as opposed to the previously mentioned signs where three men would certainly be necessary for a 10-meter-long sign.
• this invention provides several advantages pertaining to the structure itself.
• the struts which form and maintain the box shape may be made in various standard heights and depths, but are otherwise identical; and the longitudinal parts may be made in standard lengths. Also, in this invention there are no parts situated between the light sources and the canopy, and therefore no shadows are cast on the canopy, either.
• Figure 1 shows a section of the device having a simple embodiment form.
• Figure 2 shows a preferred embodiment form of the invention, and here only the top and outermost part of the advertising sign is shown.
• Figure 3 shows a lock fitting for the tightening member, viewed from above, and
• Figure 4 shows in section a second embodiment of the invention, also where only the top and outermost part of the apparatus is illustrated.
• the drawing in Figure 1 further shows the box-shaped advertising sign having front 2, top side 3, underside 4 and rear side 5.
• the front 2 may also face downward or upward, or the advertising sign 1 may have a message for several, sides, on the ends, etc., but in the interest of simplicity only the aforementioned designations are used both in the specification, patent claims and abstract.
• On the drawing in Figure 1 are also struts 6, which must be so strong that they do not substantially "give” or bend when the canopy 7 is mounted on apparatus 1.
• a fluorescent light/tube 11 or the like Inside the apparatus, e.g., on a rear panel 10, is mounted a fluorescent light/tube 11, or the like.
• the flexible and translucent canopy 7 is mounted at the front edge of apparatus 1.
• Canopy 7 is brought over the outside edge 12 of panel 9.
• the edge 12 is bent in an angle inclining upward/downward and inward 13, and its outermost edge is bent inward and back in order for canopy 7 to have a round edge over which to slide.
• the outermost edge of canopy 7 is inserted down between tightening member 16 and the upward bent portion 15 thereof, with the actual bend-edge 17 bearing against cover panel 9.
• a short distance from bend 17, the upward bent portion 15 is bent outward and back again 18 to form a rounded edge for canopy 7, which is secured between the mentioned parts by their being either pressed together or held together with the aid of screws, pins, glue or the like.
• Tightening member 16 is then placed in approximately perpendicular position inside edge 14 with its bend 17 against cover panel 9.
• cover panel 9 is tightened, and the tightening member can then be fastened to the cover panel 9, e.g, with the aid of pins, screws, or the like.
• covers 23 may be mounted over the tightening members 16, as shown, and secured with screws, pins, or the like 24, and the screws on the tightening members 16 may then be omitted.
• the tightening members 16 may be made relatively short. When the apparatus is to be opened, e.g., to replace the fluorescent tube, one is able, e.g., simply to open it at the bottom and let the canopy hang loose while the work is done.
• Figure 2 on .the front edge of apparatus 1, at the top, bottom, and on the ends of the struts 6 are attached profiles 25, and on these profiles are formed longitudinal means (37) in which may be placed aluminum strips to ensure that the abutting profiles are brought into precise alignment.
• Outermost toward front 2 is a rounded edge over which canopy 7 may easily be slid.
• Within the profiles 25 having a bottom 26, on the side closest to front 2, are situated a plurality of longitudinal tracks 27 over one another, with their openings facing inward in profiles 25.
• the top wall 28 over the uppermost track 27 is shorter than partition wall 28' between the two top tracks 27; and partition wall 28" extends farther out than partition wall 28 ' .
• On the opposite side of profile 25 are a plurality of longitudinal grooves 29 opening inward in profile 25 and having bevelled edges 30 outermost on the underside of each groove 29.
• the tightening members 16 and the attachment of canopy 7 thereto are, here, exactly the same as what is described for Figure 1, except that here there is a bent-over edge 31 serving as a stiffener for tightening member 16.
• a bent-over edge 31 serving as a stiffener for tightening member 16.
• Lock fitting 32 is pressed all the way into groove 29 until the upper section 31 of tightening member 16 springs up outside the downward bent flaps 34 and effectively locks tightening member 16.
• the tightening members 16 and the fastening of canopy 7 thereto are precisely the same as are shown in Figure 2, except that the tightening members 16 are bent 35 at the lower end thereof.
• Profile 25 has, on the top side 3 and underside 4 of apparatus 1, channels 36 opening, respectively, upward and downward along the entire profile 25. The side edges of channels 36 incline toward the rear side 5 of apparatus 1.
• the bent portion 35 of tightening member 16 is inserted down into an appropriate channel 36, and the upper part of tightening member 16 is then swung away from the front 2 and toward the upper side 3 or underside 4, respectively, and is secured there as described previously.
• the profiles 25 are also beneficial in the respect that they are very rigid, thus preventing the forces imparted by the canopy 7, when being tightened, from causing any substantial downward bending of the profiles 25.
