SYSTEM FOR PROTECTING AND IMPROVING THE MAIN PARTS FOR A PLAIN BLIND FITTED INSIDE A GLASS-ENCLOSED CHAMBER

Description

[0001] The present patent application concerns a system for protecting and improving the main parts used for operating a plain blind mounted within a glass-enclosed chamber, subject of the patent applications Italy MI2003A 001902 - 3.10.03, PCT IT 03 00715 - 5.11.03 entitled "System for operating a plain blind within a chamber enclosed by panes of glass" by the same applicant. Document WO2004/001175A discloses all features of the preamble of claim 1 The plain blind is mounted in a glass-enclosed chamber on a frame consisting of four metal bars, an upper one, a lower one and two lateral bars, and by four corner pieces of plastic material, two at the top and two at the bottom.

[0002] The upper end of the blind is mounted on a blind roller placed underneath a fixed upper box, and is pulled by two devices acting on the blind roller and on the lower end of the blind fixed to a mobile box.

[0003] The upper corner pieces of the frame fit into the inner sides at the top of the frame's lateral bars by means of a rectangular aperture whose width is slightly less than that of said inner sides and whose length corresponds to the greater length of the upper corner pieces.

[0004] Advantageously the blind roller is protected at its sides by two rectangular substantially flat longitudinal horizontal aprons, shaped on their upper longitudinal edges substantially like an upward-facing "C", that hook by elastic pressure into the substantially T-shaped lower longitudinal edges of the fixed upper box. Preferably the lower longitudinal edges of the aprons curve inwardly to form a cavity H in each one, the geometrical axis of which substantially coincides with that of holes made in the lower end of the upper corner pieces of the frame, so that self-threading screws can be screwed into said cavities through said holes, simultaneously stabilizing both the upper corner pieces of the frame as well as the aprons, to provide maximum protection for the blind when being wound up or let down and when such movement is completed.

[0005] Advantageously the vertical lateral bars and the lower horizontal bar of the frame present orthogonal channels in their sides facing the blind, practically in line with said sides, the channels being shaped substantially like a square "U".

[0006] Preferably the width of the mobile box at the lower end of the blind with its terminal H plugs, is less than the width of said channels so that the mobile box, and therefore the lower end of the blind, can slide freely inside them.

[0007] Advantageously the characteristics of the two lateral bars of the frame and those of the lower bar are substantially the same.

[0008] In a preferred embodiment external base of the fixed upper box forms, together with the pair of H aprons, a chamber in whose top a lighting device is placed lengthwise.

[0009] This lighting device may consist of LEDs and extend along the whole length of said chamber.

[0010] The system subject of the present patent application offers evident advantages.

[0011] Insertion of the upper corner pieces of the frame inside its lateral bars not only fully protects said corner pieces of plastic material, but also prevents their coming in contact with the material used for the external seal of the glass-enclosed chamber, lessening the risk of contamination and improving the overall seal of the system.

[0012] The aprons not only protect the blind when being wound round the blind roller, as well as the blind roller itself, but also improve stabilization of the whole unit by means of the connections made with self-threading screws through the upper corner pieces and through said aprons.

[0013] The fact that the lower mobile box - a decisive element where plain blinds are used - slides in a double vertical lateral guide, not only ensures full protection for the blind, but also improves screening against light from outside.

[0014] The lighting device placed on the external base of the fixed upper box forming a chamber with the pair of aprons, consists of a longitudinal light-emitting means aligned with said base of the box, which can extend right across said chamber, illuminating the internal glass pane in a pleasing as well as useful manner, and therefore the room where the glass-enclosed chamber has been mounted, while the same light is dimmed on the external glass pane by the apron where it touches against the blind itself Particularly advantageous is the use of LEDs that occupy little space but give a light which is both cold and of considerable intensity.

[0015] Summing up these advantages, the improvements here described ensure maximum operational safety, a long life for the glass-enclosed chamber as well as a high degree of environmental comfort.

[0026] Plate 5/5 Fig.10. Glass-enclosed chamber in Fig 1, in position, front view.

[0027] Plate 5/5 Fig. 11. Glass-enclosed chamber with LED lighting device, cross section.

[0028] The glass-enclosed chamber 300 comprises glass panes 6 and 7, the frame 302 having four right-angles, formed of four flat metal tubular bars of a substantially rectangular cross section, an upper bar 20, a lower bar 310, and lateral bars 312 joined by corner pieces of plastic material, top left 315, top right 317 and bottom corner pieces 50.

[0029] In the upper end of their inner side 320, the lateral bars 312 present a rectangular aperture 322 (Figure 2) the width of which is slightly less that of the inner side 320 and whose length substantially corresponds to that of the oblong body of the upper corner pieces 315 and 317.

[0030] On their inner side 320, the lateral bars 312 also present parallel sides 324, set at 90° in relation to said inner side 320, said parallel sides 324 forming a substantially U-shaped channel 326 within which slides the blind 112 with the mobile box 376 at its lower end, while the top 110 of the blind 112 is wound round a cylindrical blind roller 113, with pins 116, 118 turning in their seats 338, made respectively in the substantially equal corner pieces 315 and 317 (Figure 7).

[0031] The blind 112 remains in position under the fixed upper box 360.

[0032] In the inner side 328 of the lower bar 310 there is also a square U-shaped channel 330 substantially the same as the square U-shaped channels 326 in the lateral bars 312.

[0033] The upper corner pieces 315 and 317 (Figure 7) comprise an oblong body 346 sized so as to penetrate inside the lateral bars 312 of the frame 302 (Figure 1).

[0034] Anchored to the fixed upper box 360, at the position of the blind roller 113, are aprons 364 and 366 held in place by means of substantially C-shaped parts 368 that hook onto the substantially T-shaped projections on the lower lengthwise edges of said fixed upper box 360 (Figures 3-6).

[0035] The aprons 364, 366 are then rotated towards the blind 112 wound round the blind roller 113, as shown in Figure 6, by means of their terminals 374, as indicated by the arrows 375.

[0036] At the lower ends of the aprons 364, 366 are hook-shaped pieces 372 with small cavities in which the self-threading screws 344 can be screwed after passing through the holes 340 made for them in the lower ends of the corner pieces 315 and 317 (Figures 7, 8).

[0037] Said corner pieces 315 and 317 present an inner wall 334 (Figure 7) that makes contact with the fixed upper box 360, said wall 334 having an extension 336, made to penetrate inside said fixed upper box 360 and, at its lower end, short peg-like projections 342 that press externally against the hook-shaped pieces 372 at the lower ends of the aprons 364 and 366.

[0038] The mobile box 376 (Figure 2) at the bottom end of the blind 112, can slide along the square U-shaped channels 326 in the lateral bars 312 and, when the blind 112 has been fully pulled down, can settle inside the channel 330 in the lower bar 310.

[0039] For this reason the mobile box 376 and its terminal plugs 378 with pegs 380 (Figure 2) have been made of a width compatible with the internal width of the channels 326 and 330.

[0040] Inside the the mobile box 376 is a heavy bar 382 to give sufficient pull on the blind 112.

[0041] Figure 1 shows that the dimensions and positions of U-shaped channels 326 and 330 are such as to ensure reciprocal matching.

[0042] Figure 10 illustrates the glass-enclosed chamber 300 with the sealing material filling its perimeter 301.

[0043] At the top of the chamber 386, formed by the base of the fixed upper box 360 and aprons 364 and 366, a support 388, for a LED-operated lighting device 392, is held in place by adhesive (Figure 11).

[0044] It will be clear that this device throws a pleasing light (arrows 394) from the internal pane 7 into the room where the glass-enclosed chamber 300 is installed, while any light on the external pane 6 is dimmed by the presence of the blind 112.
