Description

SCREEN SCREEN.

  The invention relates to a folding screen.

  As we know, a folding screen is composed of a plurality of hinged panels and joined together by hinges, used either to protect against

  cold, or to hide something.

  The invention relates to a screen of the type in question which is easy to build, economical, transformable, and can be easily dismantled,

  transported or modified, and in which we can

  niere convenient thanger the decor without damaging it.

  This folding screen constituted by a plurality of panels hinged together by hinges and in which said elementary panels include a frame

  rigid on which a flexible surface is placed

as the decor, is characterized:

  - on the one hand, in that the rigid frame is cons-

  formed by at least two substantially vertical uprights, interconnected by crosspieces, said uprights being constituted by profiles having a cross section

  U-shaped, the branches of which are directed towards the former

  each profile comprising a second profile in

  U, homothetic to the first profile, and inserted in this-

  itself to tighten the decorative surface; - and secondly, in that the decorative surface, inserted in the gap formed between the two profiles

  U-shaped homothetics of the second amount of the first

  mier panel is inserted also without solution of

  continuity in the gap formed between the two profi-

  U-shaped homothetic strips of the first upright of the next second panel, so that said surface

2 2625666

  flexible decorative thus forms hinge of articulation

between two adjoining panels.

  Advantageously, in practice: 5. the decorative surface is a fabric; the uprights are vertical; the two homothetic profiles of the same amount are clamped against each other by taking the decorative sandwich surface; 10. the two homothetic profiles of the same amount are tightened one against the other by a nut-bolt system; the crosspieces which connect the two uprights of the same frame have a profiled section in the shape of a gutter U, or even in H; the assembly of the uprights with the crosspieces is carried out by adjusted interlocking and keys; the two homothetic profiles of the same amount

  are clamped against each other by means of a

  vettes; the tetragonal frame has the shape of a square, a rectangle or a trapezoid; the substantially horizontal crosspieces in the form of a gutter include at least one lamp

lighting.

  The manner in which the invention can be implemented and the advantages which result therefrom will emerge more clearly from the following exemplary embodiments, given by way of

  indicative and not limiting, in support of figures an-

attached.

  Figure 1 shows in summary perspective view a

  characteristic framework of the invention.

  Figure 2 is a sectional representation of two

  amounts forming a hinge characteristic of the invention

  tion. Figures 3 and 4 schematically represent two possible paths of the decorative flexible surface

  from one upright to another thus forming a hinge.

  Figures 5, 6, 7 and 8 show other shapes

of achievement.

  Figure 9 shows another embodiment of assembly.

  The elementary panel characteristic of the invention

  tion designated by the general reference (1) essentially comprises (see Figure 1) two vertical uprights' respectively (2) and (3) parallel, interconnected by rigid crosspieces (4,5) U-shaped, turned

  for example up and down respectively.

  The two vertical uprights (2,3) also have a

  U-shaped section whose branches (6,7) are di-

  rigged outwards. In an advantageous embodiment, the sections (2,3,4,5) are made of aluminum or

  made of plastic and are welded together.

  According to a first characteristic of the invention, each vertical profile (2,3) has inside a second profile also in the form of U respectively (8,9), homothetic to (2,3), (see FIGS. 1 and 2), intended to sandwich the decorative fabric designated by the reference (10). This tightening is carried out thanks to a

  nut-bolt system (11) placed at the ends of the

  vertical legs (2,3) so as to pinch the fabric (10) well in the gap (12) between the homothetic U-shaped profiles of the same amount, respectively (2,8)

and (3.9).

  It goes without saying that the tightening of the U-shaped angles of (8.2, 9.3) can be carried out by any other

way than bolt nuts.

  Advantageously, the bottom of the U (2), (3) is coated

  an adhesive layer (13), as well as the outer surface

homothetic laughter (8.9).

  The decorative fabric (10) passes into the first in-

  terstice (12) of the first upright (6.8) where it is tightened, then it is stretched over the frame (A) passing over the branches (6.7), then enters the second interstice (12 ') of the upright opposite (3), then from there enters the gap (12 ") of the upright (2 ') of the following frame (B),

And so on.

  In this way, the fabric (10) not only forms the

  decoration when stretched over the frame (1), but also

  the hinge (14) passing without any con-

  continuity from a first frame (A) to the next frame (B).

  In another embodiment shown schematically in Figure 9, the assembly of the uprights (2,3) and crosspieces (4,5) is no longer by welding but by fitting and keys. The end of each crosspiece (4) is cut in the shape of a tenon (20) whose width is slightly less than the internal width of the profile (2) corresponding to be inserted in a horizontal slot (21) provided for this purpose. The post (20) also includes a light (22) intended

  to receive a locking key (23). This arrangement

  tion ensures rapid, rigid, adjusted and aesthetic mounting.

tick.

  The gutter shape of the two vertical U-shaped profiles (2,8,3,9) embedded one inside the other, not only promotes good fixation

  decor (10) stretched, without sliding, but also offers

  minimum distance between two frames (A) and (B)

  successive. Furthermore and above all, this provision

  puts these two frames (A) and (B) to be easily

  beaten 180 on one another on the side of the hinge (14). This hinge (14) (see Figure 3) has

  at least twice the width

  wing protector (7) of the characteristic profile.

  The closed folding direction of the screen is defined at each hinge (14) by the side o said hinge

  is placed. The folding of the screen can therefore be chosen

  if during assembly by the arrangement of the decorative surface (10) in this or that way on the frames

  successive (A, B). On request, we can thus obtain

  hold a Z-fold (Figure 3) or a trypti-

that (Figure 4).

  If in the examples above, the two uprights (2,3) are vertical, it goes without saying that they can be

  also tilted relative to each other for-

  sea a tetragonal frame in the shape of a trapezoid for example.

  Figure 5 is another embodiment of

  the invention particularly suitable for a screen of-

  before being placed on stairs (25) and around a column (26). The decorative surface (10), normally flat; is mounted loose on the first frame (A), which then forms Venetian blind style folds. Then this decorative fabric (10) is then stretched to form a hinge

6 2625666

  between the frame (A) and its next frame (B) where it is also released. Leaving the frame (B), the decor fabric (10) is left free over a determined length so as to be able to step over the staircase (25). The fabric is then introduced into the following frame (C) o as

  previously he is released. It goes without saying that for

  maintain good stability, the frame (C) must be provided with legs and brackets, while on the other hand, the

  torque (A, B) is freestanding as soon as the hinge

  téristique makes an angle less than 180. Leaving the frame (C), the decor fabric (10) can surround a column (26) or another similar obstacle by joining the other

  freestanding group of executives (D + E + F).

  In the embodiment shown in Figure 6, the assembly is of the "wedge-shaped" type. In one embodiment, the unitary frames (G, H, I, J, K) have a substantially trapezoidal geometry, while the fabric

  decor (10) has a standard rectangular shape. We ob-

  then holds a spectacular arrangement of the panels (G-K) in space, forming an oblique broken arc or a

  pyramid according to the mounting of the characteristic hinges

  ques. In another embodiment shown in Figure 7 called "oblique", the unit frames (L-T) are at least partly of them substantially in the form of

  parallelepipeds (warped rectangle). We can thus

  hold a screen with oblique hinges

"bent over".

  In the embodiment shown in FIG. 8, it is possible to combine oblique and triangular shapes, which thus makes it possible to hide a foot of wall or

  to be fixed to the wall to form an awning.

  Thus, the same fabric (10) can be mounted without

  continuity solution on geometry-shaped frames

  very diverse, which allows obtaining

  very varied figurations and by there, interior decorations

finished.

  The arrangement according to the invention has many

  many advantages compared to the screens marketed today. We can cite: - first and foremost, the fact that the fabric

  (10) itself forms a hinge, which facilitates

  production and installation;

  - the possibility of making oblique hinges

  What the hinges do not allow

previously used;

  - the fact that the assembly is easily demon-

table;

  - the fact that the decor can be modified on demand and at the lowest cost;

  - the possibility of using the set as a light-

  preferably inserting into the cross rails

  (5) an appropriate lighting system (30,31)

(see figure 4).
