Abstract

LUMINOUS SIGN BOX INCLUDING AT LEAST ONE FRONT PLATE 13 SHAPED OF A THIN SHEET CURVED LOCALLY FOLLOWING A LONGITUDINAL AXIS OR FOLLOWING SEVERAL LONGITUDINAL AXES SENSITIVELY PARALLEL, THIS SHEET HAVING A PROFILE NEARLY SHAPED UNDER THE NERVURES. THESE RIBS EXTEND IN PLANS ABOUT PERPENDICULAR TO THE SAID LONGITUDINAL AXES, AND CAVITIES 18 CAN POSSIBLY BE PROVIDED IN THE PROFILED FRONT PLATES FOR THE INSERTION OF SIGNS OR SYMBOLS TO BE DISPLAYED. THUS, THESE PLATES ARE SELF-SUPPORTING AND MAY BE FIXED DIRECTLY ON THE FLAT SURFACE OF A WALL. ALTERNATIVELY, A PROFILED FRONT PLATE MAY BE ATTACHED TO A SECOND FRONT PLATE WHICH IS IDENTICALLY PROFILED AND CURVED, SO TO FORM A SURFACE OR SELF-CONTAINED LIGHT SIGN BOX.

Description

i

  The present invention relates to a boot maker

  light barrier comprising at least one front plate, and in which one or more light sources are arranged,

such as fluorescent tubes.

  We already know many models of bootmakers

  illuminated signs intended to be mounted on a flat wall.

  A common feature of all these models is that they are

  made up of a large number of parts.

  The object of the present invention is to provide a luminous sign housing made up of a small number of parts.

  The subject of the invention is a boot maker with a sign

  miner including at least one front plate which is locally

  curved or folded along a longitudinal axis or along more

  roughly parallel longitudinal axes, this front plate having a ribbed profile, the ribs roughly

  parallels extending in planes forming a predefined angle

  terminated with said longitudinal axes and preferably being perpendicular thereto, cavities can be provided in said front plate for the insertion of signs or symbols to be displayed Thus, the front plate is self-supporting

  and can be attached directly to the flat surface of a wall.

  According to one embodiment of the invention, the profiled front plate, curved and fixed to a second plate

  front which is contoured and curved in much the same way

  nière, so as to form a shoemaker of a projecting or separate illuminated sign In this embodiment, the shoemaker can

  be supported at its end surfaces.

  Various embodiments of the invention will be described below with reference to the accompanying drawings in which:

  Fig 1 shows a shoemaker of light sign

  neuse according to the invention, which is fixed to the facade of a bat-

  timent; Fig 2a is a perspective view of the light sign housing of Figure 1; Fig 2b is a sectional view of part of the profiled front plate;

  Fig 3a is a front view of a boot maker

  protruding luminous sign, according to the invention; and Fig 3 b is a city view of the boot maker of the

figure 3 a.

  The illuminated sign boot 11 shown on

  Figure 1 is mounted on the facade of a building 12 and com-

  takes at least one front or front plate 13, in which

  there are one or more light sources, not shown

  tees, such as fluorescent tubes Front plate 13 is formed from a thin, curved, aluminum foil

  or folded locally at 14 along a longitudinal or following axis

  with several roughly parallel longitudinal axes, including

  me we see it in figure 2 a The profile is constituted by

  approximately parallel bosses or ribs 15 extending

  in planes preferably perpendicular to said

  longitudinal axes It follows that the front plate 13 is re-

  laterally robust, partly thanks to the work hardening made during stamping and also thanks to the rigidity provided by the ribs By producing a profile with symmetrical ribs, by

  example by giving these ribs the form of isocè trapezoids

  them, we get a predetermined symmetry of the distribution

  The front plate is fixed either to a rear plate.

  re flat, either directly on the facade of building 12 via the

  oblong attachment or fixing means

  gue (not shown) These attachment means can possibly-

  Lement consist of brackets or fittings The ends of the case are closed by plates 16 forming lids Translucent acrylic plates or units 17 corresponding to signs or symbols to be displayed can be inserted into cavities or openings 18 formed in the

front plate 13.

  This luminous sign box presents in part

  the advantage of being made up of a very small number of parts. According to the other embodiment shown in FIG. 3, the curved profiled front plate is leaned and fixed to a second front plate 19 which is profiled and curved in an identical manner, thereby forming a shoemaker

  of illuminated sign 20 projecting or separating This boot maker

  light sign is also pretty much self-supporting, so

  that it avoids the use of reinforcing elements, as well as

  separate upper and lower support elements

  Please note that the front plates are the same length.

  these can be optionally fixed to each other by the in-

  internal means of connection or attachment, (not

  shown), before mounting end plates 21.

  The boot of a projecting illuminated sign can optionally be supported at its two ends by means

amounts 22.

  These front plates offer the particular advantage

  to be cut on site.

  The ribbed plates are curved or folded to

  approximately 1800 in total, the radius of curvature being included

be 3 and 20 cm.

  The profile may alternatively have a shape

of continuous ripples.
