Definitions

  • the invention relates to a reversible blind comprising: a series of hingedly connected slats; a roll-up drum mounted on a shaft for rotation and having slat pulling means; drive means for said drum; a first pair of guides for receiving the side edges of the slats, in a conventional rolled-down position thereof and a second pair of guides for receiving the same edges in a reversed rolled-down position thereof; a rotatable arcuate shell-like casing coaxial with at least the end portions of said drum; two fixing discs fixedly attached peripherally to said shell-like casing; a clutch device adapted to associate said casing to said drum; spring means urging said device; and locking means for said casing.
  • blinds have one side which, in the rolled-down position thereof, is on the inside of the opening receiving the blind, whereby it is perfectly accessible to the user and is easy to clean.
  • the opposite side is either rolled up or is on the outside of the opening in which the blind is located. Therefore, when this opening is not accessible from the outside (as is the different cases of a balcony, terrace or like construction), this opposite side may not be cleaned by the user, unless costly and/or hazardous positions are adopted, either by hanging down from higher levels or climbing up from lower levels.
  • the blind referred to in the foregoing paragraph has certain minor drawbacks, some of which relate to the space, at times excessive, required for installing the roll-up drum, the clutch device and the drive means.
  • said clutch device comprises: a ring member fixedly attached to said drum, situated at one end thereof and provided with axially extending bores; axially extending orifices formed in said fixing disc and which are adapted to be aligned with said bores; a free disc, coaxial with said drum, provided with a eye and axially extending pins passing through said orifices and adapted to be inserted in said bores; and an operative means, provided with a locking pin and adapted to move said free disc axially between a first position in which said pins are inserted in said bores and said locking pin is not engaged with said eye, and a second position in which said pins are not in said bores and said locking pin is in said eye.
  • said spring means urge said free disc towards said first position and said operative means is an electromagnet adapted to attract said free disc from said first position to said second position, overcoming the force of said spring means.
  • said eye of said free disc is a notch; said spring means urge said free disc towards said second position; and said operative means is a coupling wedge (a) having a shoulder, a first rabbetted surface and a second advanced surface, and (b) may slide in a direction transverse to said axial extension between a disengaged state in which said shoulder is inserted in said notch and said first rabbetted surface engages said free disc (directly or with an intermediate washer) causing the latter to be in said second position and an engaged position in which said shoulder is external to said notch and said second advanced surface is engaged with said free disc, causing it to be in said first position.
  • a coupling wedge (a) having a shoulder, a first rabbetted surface and a second advanced surface, and (b) may slide in a direction transverse to said axial extension between a disengaged state in which said shoulder is inserted in said notch and said first rabbetted surface engages said free disc (directly or with an intermediate washer) causing
  • each of the guides of the second pair of guides should form a space having a vertical bottom wall and opposite thereto a vertical aperture flanked by two narrow flanges, there being in said space a cover plate for covering said aperture and having at the upper end thereof an extension sloping towards said bottom wall, there being at least one spring urging said cover plate against said flanges, said cover plate yielding towards said bottom wall when the blind slats are inserted in the guide.
  • one guide of the first pair of guides and one guide of the second pair of guides form part of a single structure having an intermediate separating land.
  • the blind has a plurality of hingedly connected slats 2 in such a way that a groove 4 ( Figures 10 and 11) is defined between each pair of adjacent slats 2.
  • Each of these ribs is normally continuous, although they may be formed by a plurality of aligned ribs.
  • the drive means for the rotation of the drum.
  • these means are formed by an electric motor (not shown) which is preferably housed within the drum; in another case, the drive means comprise a windlass 10 (Figure 9) driving the shaft 7 and being associated through a joint 12a with a not shown rod.
  • the blind is provided with the first pair of guides 12 ( Figures 5, 8, 10 and 11) along which the slats 2 are conventionally rolled down.
  • a second pair of guides 14 is required ( Figures 5-8, 10 and 11), also with a guide on each side of the opening.
  • Each guide 12, 14 has a vertical bottom wall 15 and a vertical aperture 17, facing the bottom wall 15.
  • one guide 12 of the first pair of guides and one guide 14 of the second pair of guides form a single structure 16 ( Figures 5, 8, 10 and 11) which may be obtained either by extrusion or from a subsequently formed cold-rolled steel strip.
  • the structure 16 has an intermediate land 18 keeping the two guides 12 and 14 at a suitable distance to facilitate the two ways of rolling the blind down.
  • the blind is normally frequently rolled down and up in the conventional way from and to the rolled-up position around the drum 6.
  • reverse unrolling only occurs from time to time, whereby the second guides are generally left unused for relatively long periods of time.
  • the invention contemplates that the vertical aperture 17 of the inner space 20 of the second guides 14 be flanked by two narrow flanges 22 and that inside the space 20 there is a cover plate 24 which may cover the aperture 17. There are springs 26 urging the cover plate 24 against the flanges 22, closing the aperture 17.
  • Each cover plate 24 is provided with an upper extension 28 preferably arcuately sloping towards the bottom wall.
  • This extension 28 is pushed by the first slat 2 of the blind ( Figures 5-8) when reverse rolling down is started and this push overcomes the force of the springs 26 so that the cover plate recoils to the position shown in phantom lines in Figure 5.
  • at least the first slat 2a be provided with a side reinforcement 30.
  • the guides 12, 14 are located offset from the vertical line of unrolling of the blind slats, as may be seen in Figure 11. Reference is made hereinafter to the way of achieving a good operation of the blind in the non-aligned position.
  • the arcuate shell-like casing 32 is preferably a one-piece member and is coextensively coaxial with the drum 6. Nevertheless, the invention also contemplates the possibility of the casing 32 being formed by two aligned portions, each of which is coaxial with the end portions of the drum 6. Herein, this item is sometimes called a tile.
  • the tile is attached to two fixing discs 34, one at each end of the tile 32 and attachment is preferably made by screws, pins or the like which are inserted in some of the bores 36 ( Figure 12). Where the casing 32 is two-part, each of them is attached to a corresponding fixing disc 34, extending in overhang over a distance.
  • a supplement 37 substantially diametrally opposed to the casing 32 and of a substantially narrower width. It is also contemplated that the supplement 37 be formed by two aligned portions, each of which is attached to the corresponding fixing disc 34. The presence of this supplement 37 -- in one or two portions--facilitates the rolling up of the blind, without hindering the reverse unrolling in any way whatsoever.
  • the tile or casing 32 may be drivingly attached to the drum 6 (whereby it rotates at the same time as the drum), or it may be independent from the movement of the drum.
  • the blind operates as a conventional blind, i.e., the ribs 8 of the drum 6, on being inserted in the grooves 4 between the slats 2, pull the blind along, moving it between the rolled-up position around the drum (and therefore at least in part around the shell-like casing 32) and the rolled-down position along the first pair of guides 12.
  • the tile 32 itself prevents the blind from being unrolled along the second pair of guides 14 since it closes the access thereto.
  • the device comprises a ring member 38, fixedly attached to an end portion of the drum 6 and having, preferably, four axially extending bores, i.e. the centre lines of these bores 40 are generally parallel to the centre line of the drum 6.
  • the fixing disc 34 located on the same side as the ring member 38 has also axially extending orifices 42. All the bores 40 and all the orifices 42 may be aligned simultaneously.
  • the device comprises furthermore a free disc 44, mounted on the shaft of the drum 6 and which, of itself, is not bound to the rotation of the shaft.
  • the free disc 44 is provided with an eye 46, which in the case illustrated in Figures 3 and 4, must be in the form of a notch, i.e.
  • the free disc 44 is also provided with also axially oriented pins 48 which are inserted in the respective orifices 42 of the fixing disc 34, whereby the free disc 44 is caused to rotate with the fixing disc 34.
  • the pins as explained hereinafter, may also be inserted in the bores 40 of the ring member 38 and it may be seen in Figures 1 and 3 that the pins 48 have not been inserted in the bores 40, contrary to what is seen in Figures 2 and 4.
  • the clutch device is provided with an operative means having a locking pin 50 which may be inserted in the eye 46 so that, when it is inserted, it blocks the free disc 44.
  • a locking pin 50 which may be inserted in the eye 46 so that, when it is inserted, it blocks the free disc 44.
  • This operative means is adapted to cause axial movement of the free disc between a first position ( Figures 2 and 4) and a second position ( Figures 1 and 3).
  • first position the pins 48 are inserted (further to in the orifices 42) also in the bores 40 of the ring member 38, while the pin 50 is not engaged in the eye 46.
  • second position referred to hereinbefore
  • the locking pin 50 is in the eye 46 and the pins 48 are only in the orifices 42, but not in the bores 40.
  • the operative means comprises a spring 52 and an electromagnet 54.
  • the spring 52 urges the free disc to be spaced apart from the electromagnet 54 and, therefore, in the first position of Figure 2.
  • the electromagnet 54 may overcome the force of the spring 52 and attract the free disc 44 towards the magnet and, therefore, to the second position illustrated in Figure 1.
  • the locking pin 50 is inserted axially in the eye 46.
  • the operative means is provided with a spring 56 which (unlike the spring 52) urges the free disc 44 to the second position thereof as illustrated in Figure 3, i.e., with the pins 48 removed from the bores 40.
  • the operative means comprises furthermore a coupling wedge 58, which is provided with the locking pin 50 (which in this case is inserted by way of a transverse movement in the eye 46, which is open along one edge).
  • the spring 56 urges the free disc 44 against the wedge 58 which has a first rabbetted surface 60 and a second advanced surface 62.
  • the surfaces 60, 62 are preferably the result of portions of different thickness of the coupling wedge 58.
  • a washer 64 or the like is preferably inserted between the free disc 44 and the wedge 58.
  • This wedge is moved transversely alternately as indicated by the arrows 66 in Figures 3 and 4 and is provided with a sloping plane 66 facilitating the movement thereof and which is limited in both directions by the length of an elongate hole 70.
  • the pins 48 of the free disc 44 must be aligned with the bores 40 of the ring member 38 of the drum 6. This position occurs at least when the blind is fully in its normal rolled-down position and it is usual to start from this regular position to start the blind on its reverse roll-down.
  • the clutch device comprises an electromagnet 54, it is de-energized by pressing an appropriate switch.
  • the device comprises the coupling wedge 58, the wedge is moved in the conventional rolled-down position in the direction of the arrow 66 of Figure 4, it being possible to use conventional devices to facilitate this movement, as well as the reverse movement.
  • the clutch device comprises the electromagnet 54
  • the electromagnet in the position shown the electromagnet is de-energized, whereby the spring 52 operates to urge the free disc 44 to the first position thereof. From there, when the blind is operated, it moves to the reverse rolled-down position.
  • the clutch device comprises the coupling wedge 58
  • the wedge 58 in the aforementioned conventional fully rolled-down position of the blind, the wedge 58 is moves upwards (arrow 66 in Figure 4) and the desired first position is obtained.
