Definitions

• roller blinds composed of horizontally articulated slats, which may be manually wound around a horizontal shaft with a belt, or automatically, by means of an electric motor.
• the uppermost slat is integral with the shaft, which bears the entire weight of the blind, and this is the reason why it must be carried by strong supports, which are permanently fastened to the wall.
• roller blinds in particular, and of blinds in general is precisely the complexity of the twofold installation procedure: first of all, it is necessary to fasten the shaft supports , and then to fix the wooden box enclosing the space above the window/door housing the roller blind assembly.
• Another drawback of roller blinds is the large amount of space required to house the blind when it is fully raised, i.e.
• This invention relates to window and door blinds which, when fully compacted, i.e. open, occupy less space than the current type of roller blinds and, in any case, less than the thickness of the wall in which they are contained, so that the box housing the blind is perfectly flush with the wall on the inside.
• This invention also relates to window and door blinds whereby all the components may be installed and supported inside the relative box, so as to make it easier and faster to install the blinds, since all that is required is to place the box inside the space above the wmdow/door and fasten it to the wall.
• the width of the blind coincides with the width of one slat, since all the slats lie precisely one on top of the other, forming a pile of constant width, regardless of the number of slats composing the blind, whereas in the case of roller blinds, the greater the number of slats composing the blind, the larger the diameter of the spiral formed by the blind when open.
• the first or uppermost slat is fastened directly to the top of the box or, alternatively, when the blind is fully raised, it is in contact with the top of the box, while when it is fully lowered it goes to lie, by means of a pm, on a support above the pin guide, so as to reduce the overall height of the blind.
• the blind is raised by rotating two cams, which engage the heads of the pins on the middle of each slats and either drag them upwards or push them downwards.
• a chain-based or other similar system may be used, with the further advantage of requiring a smaller diameter than the cams and, therefore, enabling a further reduction of the box's width.
• more than one pin may be applied at the ends of the slats, but the additional ones will not have rounded heads.
• the two lateral cams are driven manually, with a belt, or by a motor, through a set of cogged wheels connected the one to the other and to a driving shaft; the cogged wheels are housed inside an adequately sized metal box, capable of withstanding the effort required to raise and lower the blind ; the whole assembly is contained inside the box.
• Fig. 1 shows a perspective and schematic view of the blind, when it is fully raised inside the box; Figs .
• FIG. 2 , 3 and 4 show a couple of slats in the following positions, respectively: coplanar and detached ; coplanar and touching ; and superimposed, the one on top of the other, respectively;
• Fig. 5 shows the RH part of the box with some of the folded slats;
• Fig. 6 is fig. 5 shown from the left toward the right;
• Fig. 7 shows a cross-section of a slat near its end
• Fig. 8 shows a cross-section of the lateral guides
• Fig. 9 shows the slats with the hooks grouped together
• Fig. 10 shows the slats in fig. 9, but separated
• Fig. 11 gives a different view of the slats.
• the present blind comprises a series of slats (1) hinged the one to the others by means of connecting elements (2) with curved ends (2a) , which hook into the slots on the edges of each slat.
• connecting elements (2) with curved ends (2a) , which hook into the slots on the edges of each slat.
• a semi-circular slot (la) closed by a rounded rib (lb) , which engages the curved lower end of the connecting element (2)
• a larger almost rectangular slot (lc) which also features a rib (lb) similar to the one mentioned above, and which engages the curved upper end of the connecting element (2) .
• the slot (lc) is large enough to accomodate a part of the connecting element (2) , when two slanted and coplanar slats (1) come into contact (see fig. 3) ; for construction purposes, the slots la and lc may also be centred (see fig. 11) .
• the slots (la and lc) are decentralized and located at the opposite ends of each slat (1) , therefore the slats (1) must be alternately arranged so that the upper slot (lc) of one slat perfectly interfaces with the lower slot (la) of the slat (1) immediately above.
• the slats (1) are folded and arranged one on top of the other, being forced into this position by the upward thrust of the cams (9) and the pin-heads (3a and 3b) running in the guides (8a and 8b) fixed to two box-shaped partitions (8) .
• the lateral guides (7) feature a specific housing (7a) in which the rounded heads (3a) and (3b) of the pins (3) slide.
• the guides (7) continue inside the box (6) , on the RH and LH sides, above the cams (9) , where the guide (8a) splits into two arms (8b) and (8c) , at different heights, each arm facilitating the engagement of the wheels (3a) and (3b) at the ends of the pins (3) with the cams (9) , and each of the two arms of the guide being such as to oblige the slats to fold like an accordion; the pins (3) , integral with the slats placed at different heights (see fig. 5) , oblige the wheels (3a) , when the blind is lowered, to arrange themselves in the space between the guide and the preceding wheel (3b) , thus reducing the space occupied by the totality of the wheels when the blind is raised.
• the hollow space inside the box-shaped partitions (8) houses the cogwheels (10) , which are suitably protected and may act as reducers.
• the guides (8a) , (8b) and (Be) on the inside wall of the box-shaped partition (8) are so shaped and sized as to oblige the slats (1) to fold pair by pair, and to unfold in a likewise manner, to allow the pins (3) , when the blind is raised or lowered, to engage with the cams (9) at the same distance, thus achieving the uniform raising and lowering of the slats (1) .
• On the outside of one of the two box-shaped partitions (8) precisely, on the wall opposite the guide (8a) , there is attached the motor for driving the blind or the pulley activated by the belt.
