Definitions

  • the present invention relates to a framework composed by knockdown elements, a part of which are modular elements, for supporting and stretching light signs made from flexible materials, of large size, suitable for long-distance display and installed on fixed structures, such as buildings, fuel distribution stands, and the like.
  • the supporting/stretching structures for light signs in the form of a sheet made from a flexible material are normally enclosed inside a quadrangular, box-like body with large sizes in length and width, and with a small depth; the signs are then lighted by fluorescent lamps, or another type of lamps, installed inside the box-like body, close to light-reflective surfaces.
  • the sheet of flexible, transparent or semitransparent material is taut on a quadrangular framework which has the configuration of a frame, rotatably anchored onto the upper edge of the container body by means of hinges or "U"-shaped hooking means, in order to enable the interior of the box-like body to be accessed for assembly, periodical cleaning, lamp replacement and maintenance purposes.
  • US-A-817317 discloses a sign structure including a sign face frame which is pivoted or hinged to a central filler frame.
  • EP-A-0268308 discloses an illuminated sign comprising a housing with an open front and a front cover frame which is peripherally connected along its top to the housing and is pivoted to the top of the housing.
  • the supporting/stretching structure for the flexible sheet bearing the display is provided with support section bars, which are such as to enable the sheet to be diverted around the edge of the same framework and then stretched inside the interior of the latter, by winding on small metal rods capable of being put under tension on the section bars which are contained inside the interior of the box-like body; in such a way, the sheet-supporting peripheral frame can be omitted.
  • EP-A-0387030 discloses a sign assembly in which the frame members forming the sign frame are provided with a channel to receive a tensioning bar over which an edge of the material has been secured by a plurality of spring clips; the channel is formed with a series of shoulders engageable with the spring clips so that, to increase the tension of the sign, the tensioning bar is urged farther into the channel to cause the clips to engage successively inwardly disposed shoulders.
  • EP-A-0296863 discloses a sign assembly having about its periphery a rope or other member sewn into a pocket formed from the sheet adapted to cooperate with an open sided extrusion wherein the edge of the sign is restrained.
  • the dap-joint hooking system with rotation of the framework around the edge of the upper horizontal side of the box-like body requires that in said side a continuous, quite long, open hollow is provided, with an "U"-shaped hook means, of same length, being simultaneously provided on the edge of the side of the rotatable framework; and, between said hollow and said hook means, a wide room should exist in order to allow the flexible sheet-bearing, stretching-means-bearing framework to rotate; inasmuch as it requires the presence of a continuous, upwards-open hollow, this type of hooking constitutes a water and dust collecting means, with possible seepage of these substances into the interior of the box-like body.
  • section bars of the support structure are positioned in front of the lamps, so that they unavoidably cause undesired shadows to appear on the sign.
  • said structure shows the disadvantage that the upwards-openable sheet-bearing framework thereof is quite heavy, and that, when the size of the box-like body has to be changed, i.e., the depth, as well as the length and width thereof have to be changed, the section bars which support the stretching device have to be integrally replaced.
  • a purpose of the instant finding is of providing a framework for supporting and stretching light signs constituted by a sheet made from a flexible material, which framework has such a structure as to obviate the drawbacks and overcome the disadvantages associated with the structures known from the prior art and, above all, such as to display high stiffness, as well as to give easy and quick access to the structural elements housed inside the support/sheltering framework, as well as to be capable of securing an even brightness throughout the sign surface, preventing any undesired shadows from being formed on the same sign.
  • Another purpose of the instant finding is of providing a light-sign support/stretching structure which is so conceived as to result to be, at least partially, modular, and hence easily adaptable to different sizes of housing frameworks, to require a small number of metal section bars and sheet elements, to be easily and rapidly assemblable, also off place, and to secure, in any case, a perfect tightness to atmospheric agents.
  • a knockdown-elements framework for supporting and stretching light signs made from a sheet of a transparent or semi-transparent flexible material, using sign stretching elements of discontinuous-rod type suitable for being put under tension by means of pushing screws, which framework comprises, according to the present invention:
  • each of said reverse-"L"-shaped continuous section bars placed above and under said vertical section bars, shows, in the horizontal flange of said "L"-shape, a continuous hollow (groove) with quadrangular cross-section, i.e., substantially a box structure with its upper face open, ending with two continuous protrusions with cylindrical outline, around which the arched longitudinal edge of the upper and, respectively, lower structure-sealing element of the support structure is rotatably inserted, so as to allow the access to the interior of said body to be gained from the top side and/or from the bottom side.
  • a continuous hollow (groove) with quadrangular cross-section i.e., substantially a box structure with its upper face open, ending with two continuous protrusions with cylindrical outline, around which the arched longitudinal edge of the upper and, respectively, lower structure-sealing element of the support structure is rotatably inserted, so as to allow the access to the interior of said body to be gained from the top side and/or from the bottom side
  • said upper and lower rotatable structure-sealing elements are constituted by sectors having a pre-established length, and a width equal to the depth of the structure, releasably connected with one another by at least one cross element anchored inside a longitudinal groove provided at the head of each of said section bars with box-like cross-section bearing the sign-supporting flanges.
  • the flexible light sign supporting/stretching framework according to the present invention is constituted by the combination of various laminar, extruded section bars of aluminum and the like, suitable for forming a structure open at at least one of its visible faces, defined by a taut flexible sheet which constitutes the true sign.
  • the framework of Figure 1 is destined to be anchored to a whatever support means and is constituted, in the present case, by at least two continuous edge section bars 1, the length of which equates the length of the sign to be supported, and which are positioned parallel to each other, at the opposite ends, i.e., the upper end and the lower end, of quadrangular section bars 11 equidistant from each other on vertical planes.
  • Said section bars 1 (only the upper of them is depicted in Figure 1) have ( Figure 2) a cross-section with a reverse-capital-"L" shape, the vertical flange 1a of which is provided with longitudinal, channel-like guides 2-2a and so forth, suitable for receiving, in dap-joint fashion, thin metal plates 3 forming the vertical rear wall of the support framework.
  • Said thin metal plates may be omitted when the structure is anchored to a continuous support wall, such as, e.g., a masonry wall 4.
  • each "L"-shaped section bar is provided with two continuous hollows 5 and 5a of quadrangular shape, the upper face of which is partially open, and is provided with mutually opposite cylindrical enlargements 6-6a destined to constitute: the first one, a means for spring-like retaining a thin metal plate or strip 7 (Figure 1) for realizing a seepage-tight seal between the section bar 1 and the wall 4 (or another support element); and the second cylindrical enlargement 6a constituting the stationary portion of a continuous hinge destined to rotatably receive a, respectively upper and lower, sealing metal sheet 8, which constitutes the top or bottom sealing side of the structure.
  • the same longitudinal section bars 1 show, in their flanges, at least one channel-like seat 9 and, respectively, 9a, suitable for housing tight-sealing gaskets of tubular or balloon shape. Furthermore, in the vertical flange 1a of each "L"-shaped section bar a channel-like seat with quadrangular cross-section 10 is provided (Figure 2), the function of which is disclosed in the following.
  • section bars 11 with quadrangular cross-section are vertically arranged and aligned at a prefixed distance, such as to constitute support means for further section bars, as is better explained in the following.
  • Each section bar with box-like cross-section 11 is furthermore provided, at its opposite ends, with a protruding element with a quadrangular end-head 12 ( Figure 1), suitable for being inserted, in dap joint fashion, inside said quadrangular-cross-section seat 10 provided in the vertical flanges 1a of the opposite "L"-shaped section bars.
  • the various vertical section bars 11 constitute, together with the "L"-shaped section bars, a stiff framework, with which a sealing wall can be associated, when required, by means of the installation of thin closure plates 3 slidingly mounted, with overlapping, inside the opposite guide grooves 2-2a, etc., whilst, when the structure is affixed to a fixed wall, e.g. masonry wall, 4, said plates can be omitted.
  • a fixed wall e.g. masonry wall
  • Said section bars 13 are arranged diagonally inclined at 45 o to the vertical section bars, and namely, one of them is directed upwards and the other one is directed downwards.
  • each section bar 13 is placed at 45 o relatively to the common section bar 11, is designed to have different length value, as a function of the depth of the support structure, and is removably anchored to the section bar 11 with possibility of adjustment of its installation level, by an end thereof being inserted inside an "U"-shaped seat 14a associated with a hollow support section bar 14 ( Figures 1 and 4), with triangular cross-section.
  • Said section bar 14 has a cross-section having the shape of a right-angle triangle and can be anchored to the section bar 11 by means of suitable fastening means and relevant screws 15, so that the "U"-channel-shaped seat 14a, suitable for housing the end of the section bar 13, is also arranged inclined at 45 o .
  • Both section bars 13, inclined at 45 o and directed upwards and downwards respectively on a same vertical section bar 11, are then fastened against the hypotenuse side 14b by means of transversal screws 16 (only the trace of such screws is illustrated in short-dashed line in Figure 1).
  • a continuous section bar 17 ( Figures 1 and 3) is associated, which is arranged in a horizontal position and crosswise to the individual inclined section bars.
  • Said continuous section bar 17 is given an equal length to the longitudinal side of the flexible sign 18.
  • Said continuous section bars 17 constitute the support structure, to support the flexible sheet which constitutes the sign in the vertical direction and parallel to the vertical rear wall defined by the vertical section bars 11 ( Figure 1).
  • Each of said support section bars 17 has a hollow cross-section with two mutually opposite protruding flanges 17a, such as to form a channel-shaped seat with a quadrangular cross-section suitable for receiving the free end of the inclined section bars 13, which are then affixed to said protruding flanges 17a by means of transversal screws 19.
  • Said section bar 17 furthermore has its flange 17b ending with an outwards-arched end 17c performing the task of enabling the flexible sheet 18 which constitutes the sign to correctly rest on the section bar edge, to be diverted around the rounded edge 17c of said flange 17b, and then the bent edge of said sheet to be blocked inside a continuous channel-shaped seat 20 by means of stretching rods of known type.
  • the stretching of said sheet is made, in a known way, by folding the opposite longitudinal edges of the sheet 18 around the upper and lower flanges 17c, then winding said edges around quadrangular rods 21, then sliding the latter in said seat 20 and finally putting the quadrangular rods 21 under tension, by being pushed towards the bottom of said seat 20 by means of horizontal stripes 22 tightened by means of screws 23 engaged inside respective screw-threaded seats 24 ( Figure 3), using, for example, the hooking/stretching device which is the subject-matter of Italian patent application No. 22,302 A/89 filed by the same Applicant on November 8 th , 1989.
  • Each continuous section bar 17 has its upper portion 17e flat and flush with the upper surface of the flanges 1b of the "L"-shaped section bars around which the upper and lower metal sheets 8 are rotatably associated.
  • section bar 17 is provided with a protruding flange 25 and a hollow having the shape of a continous groove 26, coplanar with each other, suitable for receiving longitudinal plates which perform the task of connecting the various sectors (of pre-established length, and same width) which constitute the sealing metal sheets 8.
  • Each sealing metal sheet 8 is fastened onto the upper plane of the section bar 17 by means of equally spaced screws 27 ( Figure 1).
  • each metal sheet 8 is rotatably mounted around the cylindrical enlargements 6a, by removing the screws 27 of one or more of said sector(s) which constitute said metal sheets 8, the metal plate sector(s) can be lifted, by being turned (in shutter fashion), therefore giving access to the interior of the box-like body, from the bottom and/or from the top, for cleaning operations, lamp replacement and servicing in general.
  • a wall 28 of light-reflective material is installed, which is constituted by at least two light-reflective plates 28a-28b (Figure 1) mounted guided, at one of their longitudinal sides, on section bars 29 ( Figure 6) removably anchored, by screws, to the vertical section bars 11 and provided with parallel prismatic grooves 29a-29b inclined at 45°, inside which the individual light-reflective plates may slide until to mutually overlap, lengthwise to the structure; and, along their opposite longitudinal sides, inside analogous prismatic grooves 30 ( Figure 1) provided in the continuous section bars 17.
  • plates of light-reflective material 31 are furthermore provided anchored to the vertical section bars 11 present at least on the vertical rear wall 3, as well as usual lamps 32, also anchored to the vertical section bars 11.
  • a stretching device is provided, which is installed at the four corners and inside the interior of the box-like body, which stretching device eliminates any possible wrinkles and/or folds which may arise when the edges of the flexible sheet are bent and stretched around two adjacent sides (at 90° to each other) of the sign-bearing visible faces.
  • Said device is constituted, as depicted in Figure 7, by two length-adjustable tie-rods 33-33a anchored to the vertical section bars 11 or to other internal fixed parts of the box-like body, which tie-rods are provided with hook- or ring-shaped arched ends 34, connected to small cables 35 which, in their turn, are integral with both edge portions 36-36a which are inside the interior of the structure after said flexible sheet being folded and stretched around two adjacent sides of the quadrangular framework formed by the external flanges 17c of the continuous section bars 17 which support the stretching mechanisms.
  • Both edges, anyway folded and crumpled 36-36a are stretched by means of a stay bolt 37 interposed between the two sections which constitute the tie-rods, the coaxial ends of which are engaged with the sleeve of the stay bolt, provided at its ends with two screw-threads, the directions of which are opposite to each other.
  • the practical advantages, of use and of financial character, of the present finding consist in the possibility of providing section bars with box-like cross-section which can be both used as vertical section bars, and as diagonally inclined section bars, and are such as to enable them to be used for accomplishing structures having different sizes; in the present case, in fact, in order to increase, or decrease, the depth of the structure, it is enough that the triangular section bar 14 is shifted upwards or downwards, while the length of the section bars 13 is simultaneously reduced accordingly.
  • the support structure disclosed hereinabove can be easily assembled off place, independently of its dimensions.
