Definitions

  • This invention refers to a framework composed by knockdown- elements, a part of which at least 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 frameworks for light signs in the form of a sheet made from flexible materials, such as for instance a vinyl sheet or the like, 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 or parabolae.
  • 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 framework by means of hinges or other 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, as described, for instance, in US 4817317 and in EP 0268308.
  • the supporting/stretching structure for the flexible sheet bearing the display is provided with supporting 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 latter, by winding on small metal rods capable of being put under tension on the section bars which are contained inside the box-like body; in such way, the sheet-supporting peripheral frame can be omitted.
  • the dap-joint hooking system with rotation of the framework requires that in said side a continuous quite long open hollow be provided, to allow the rotation of the sheet-bearing, stretching-means bearing framework; this type of hooking constitutes a water and dust collecting means, with possible seepage of these substances into the box-like body.
  • section bars of the supporting structure are positioned in front of the lamps, so that they unavoidably cause unwished shadows to appear on the display.
  • a purpose of this invention is the realization of a framework for supporting and stretching light signs from flexible materials, whose structure is such as to obviate the drawbacks and disadvantages shown by the known structures, and such as to be endowed with a high stiffness, and to allow the internal structural elements to be easily and quickly accessed, so as to ensure a uniform luminosity on the whole display, without formation of unwished shadows, and such as to be constituted by structural elements of very simple shape and therefore easily and economically realizable, either from light alloys by extrusion, or by means of common sections of normal steel.
  • Another purpose of this invention is the realization of a supporting/stretching framework for light signs, designed in such a way as to be at least partly modular, to require a reduced number of profiles and to be easily and quickly assemblable, and such as to ensure, in any case, a perfect tightness to the atmospheric agents.
  • said arms for the upper and lower anchoring are arranged in mutual opposite, mirror-imaged relation and inclined at 45° relatively to said vertical bars.
  • they are fixed at the wished distance from the upper and lower ends of the vertical bar respectively, by causing the sliding of the support plate associated to the interior counter-plates along the anchoring flat surface of the vertical bar, utilizing the slot for causing the sliding of the bolts or tie-rods which connect the supporting plate to the internal counterplate.
  • the flange is fastened by tightening the connecting bolts.
  • such sheet is fastened by means of its longitudinal upper and lower edges respectively to the upper stretching section bar, and to the lower stretching bar by winding for one or more turns the sheet around said section bar, or by inserting the section bar into a continuous longitudinal eyelet provided at the end of the sheet, or utilizing any other suitable means; the stretching section bars are fixed, in their turn, to the quadrangular heads of the anchoring flanges.
  • the sheet For instance, to mount the sheet, one can fix, as a first step, the upper anchoring flanges in the wished position, and, at the free end or quadrangular head of said flanges, the upper stretching section bar, fixed, in its turn, to the longitudinal upper edge of the sheet, as will be illustrated later on.
  • the lower mobile reflective plates slide respectively upwards or downwards, translating with their upper edge onto the folded strip of the fixed intermediate plates, the latter being simply resting against said strip, as said.
  • the lower reflective plates are housed and supported in the lower part inside the continuous grooved "U"-shaped seat, and can therefore translate horizontally until they superpose to one another, so as to allow the access to the inside of the structure for the length and in the point wished, or they can be completely removed by simply shifting them upwards. In this way it is possibly to carry out easily and quickly the necessary maintenance and replacement operations on the reflective plates and the lamps, the latter being normally fixed in correspondence of the intermediate vertical fixed plates or of the upper fixed plates, or anyhow inside the structure.
  • knockdown-elements which constitute the framework according to this invention have a simple shape and therefore they can be made either of light alloy, such as aluminium alloy, when the structure has to be particularly light, utilizing in particular, in most cases, extruded sections, or of normal galvanized steel, prevarnished or the like.
  • the reflective plates are constituted by rectangular or square metal plates, varnished with reflective varnishes, or made from bright anodized aluminium alloy.
  • the stretching ?section bars may have a round or a polygonal cross-section, and their outer surface may be either smooth or provided with longitudinal grooves or protrusions to improve the adherence and the tightness of the sheet on said section bar.
  • the flexible light sign supporting/stretching framework is constituted by the plurality of hollow vertical section bars 1, 1a, 1b, 1c, etc., having a substantially quadrangular section, fixed to a support wall which is not shown in the figures, provided with the continuous longitudinal slot 2.
  • the "L"-shaped section bars 3 and 3a are arranged, on which the covering elements 4 and 4a are mounted by means of screws or dap-joints, said covering elements being constituted by suitably shaped metal sheets.
  • the upper anchoring flange 5 inclined at 45° relatively to the vertical bar and looking upwards, and the lower anchoring flange 5a, also inclined at 45° but looking downwards, are fixed by means of the supporting plate 6 engaged on a counterplate or the like not shown in the figure, placed inside the vertical bar, and special bolts or tie-rods, also not shown, which pass through slot 2 and can freely translate, when they are not tightened, towards the upper or lower part of the vertical bar, integrally with the plate and the counterplate, easing in this way the positioning of the flange in the point wished.
  • the flanges are provided with the quandrangular head 7, provided with a through-hole 8, inside which the bolt or tie-rod 9 is inserted.
  • Such bolt 9 fastens and keep in position by a ledge or a dap-joint, through the stop small plate 16, passing through hole 17, the sheet blocking flange 10, the small blocking bracket 11, passing respectively through the "U"-shaped adjustment longitudinal opening 12 provided on flange 10 and hole 13 provided on the horizontal wing of the small bracket 11, the upper stretching section bar 14 or the lower stretching section bar 14a, and the reverse "L"-shaped upper 15 and lower 15a section bars.
  • the "U"-shaped section bar which constitutes the continuous grooved 18a seat for supporting and stretching the lower reflective plates 20 is horzontally placed on the lower anchoring flanges 5a; the section bar 18 is blocked and kept in place by bolts 9 through the tightening of wing 19 between the small stop plate 16 and flanges 5a.
  • the upper reflective plates 21 are fixed and mounted with a downwards inclination; the intermediate reflective plates 22 are also fixed and vertically mounted on the vertical bars 1.
  • the lighting equipment such as lamps, fluorescent tubes and the like, not shown in the figure, are mounted on the intermediate reflective plates.
  • These intermediate reflective plates 22 are also provided in the lower part with the folded strip 23, which constitutes the upper seat for the lower reflective plates 20, which, as said, are supported in the lower part and can slide in the "U"-shaped grooved seat 18a.
  • the lower reflective plates 20 can therefore translate horizontally until they partly superpose, as shown on Fig. 3, or even until they fully superpose, to allow to have free access to the lamps or other internal equipments of the structure, or even to allow their simple removal by shifting them upwards.
  • plates 20 can translate upwards by simply sliding along strip 23, when the lower anchoring flanges 5a together with the lower section bar 14a are shifted upwards, as shown on Fig. 2, to allow the mounting and correct stretching of sheet 24, as shown on Fig. 1.
