Definitions

  • the present invention relates to a system for tilting roller blinds comprising tilting separable slats, the system being of use more particularly for blinds of the kind comprising two vertical guides and a number of slats pivotally connected at their ends to a pair of side chains adapted to tilt the slats, the slats also being connected to front chains which transmit the tilting movement of a leader slat to the other tilting slats.
  • the system according to the invention comprises in combination: a guiding peg so disposed at one end of the leader slat as to be near one of the lateral ribs of the corresponding vertical guide of the blind; a first auxiliary guiding path for guiding the peg, such path communicating with the vertical guide via a bottom passage and via a top passage, the first auxiliary guiding path being so disposed near the vertical guide that a portion of the lateral rib is interposed between the vertical guide and the first auxiliary guiding path; means which act on the peg, at least when the leader slat rises and reaches the bottom passage, to transfer the peg from the vertical guide to the first auxiliary guiding path; and peg-accompanying means so disposed as to bound a second auxiliary guiding path which extends into the first auxiliary guiding path and away from the vertical guide.
  • the guiding peg is fixedly mounted at one end of the leader slat; and the means acting on the peg comprises a resilient strip disposed near the bottom passage in extensoin of the said portion of the lateral rib, the strip extending downwards and away from the alignment of the side rib and extending some distance into the interior of the vertical guide.
  • the system according to the invention can also use a guiding peg of the kind disclosed by the aforesaid patent.
  • the guiding peg is pivotally mounted at one end of the leader slat; and the same receives resilient means which tends to urge the peg against the lateral rib of the corresponding vertical guide of the blind.
  • FIG. 1 is a partial perspective view of a blind which has the tilting system according to the invention and whose slats are in the tilted position;
  • FIG. 2 is a perspective view of one end of the leader slat, a fixedly mounted version of the guiding peg being shown;
  • FIG. 3 is a similar view to FIG. 2 but with a movable version of the guiding peg, the same being articulated to the leader slat;
  • FIG. 4 is an elevation of the casing receiving the vertical guide and the two auxiliary guiding paths
  • FIG. 5 is an elevation of the casing shown in FIG. 4 but without its cover
  • FIG. 6 is a view, on the line VIVI of FIG. 4, of the casing in longitudinal section;
  • FIG. 7 which is to an enlarged scale, is a cross-section through the casing on the line VII-VII of FIG. 4, the view including the end of the leader slat shown in FIG. 3;
  • FIGS. 8 and 9 are two elevation views of two variants of the casing
  • FIGS. l013 show the tilting system shown in FIG. 8 and, diagrammatically, part ofthe blind, during various operating phases of the tilting system;
  • FIG. 14 shows the tilting system shown in FIGS. 47
  • FIG. 15 is an oevrall perspective view of the blind showing the latter in a closed extended position.
  • the blind shown in FIG. 1 of the accompanying drawings comprises two kinds of horizontal slats-non-tilting slats 1 and inter-engaging, tilting and separable slats 2.
  • the non-tilting slats 1 connect the body of the blind to the top roller and the slat ends run inside lateral guides 3 disposed on both sides of the blind. In order that the slats 2 may tilt, their ends do not engage in the guides 3.
  • each slat 2 has at each end a top pivot 4 received in a side chain 5.
  • the two side chains 5 are disposed inside the guide 3 and are used to operate the blind.
  • the chains 5 comprise specially devised links disposed alternately as outer pairs of members 6a and inner pairs of members 6b, the ends of each pair of members 612 being disposed between the ends of two members 6a. Near one end the members 6a, 6b are formed with a slot 7; as can be seen in FIG. 7, a bushing 8 having two flanges 9 interconnects the ends of a pair of members 611 with the two ends of the immediately adjacent pair of members 617.
  • a roller 10 adapted to run on the guides 3 is disposed between the two members 6b of each pair.
  • the corresponding pivot 4 extends through the assembly formed by the members 6a, 6b, the pin 8 and the rollers 10, and such assembly is mounted pin 8 and the roller 10, and such assembly is mounted ring 12.
  • the pivot 4 can rotate freely inside the pin 8 to tilt the slat.
  • the pins 8 can move freely in the slots 7 to move the slats into and out of engagement with one another.
  • the weight of the blind itself separates the slats from one another, the side chains 5 then being at full length.
  • the slats start to close as the blind descends, and when the blind is in its fully closed position with all its slats in engagement with one another, the side chains 5 have their minimum length.
  • the same also connect the blind to the guides 3 and are used to raise and lower the blind.
  • the front chains can be of any kind appropriate for the required purpose but preferably take the form of metal link members 14 which terminate 0 in a T at their top end 15 and in closed hooks 16 at hooks 16 of the next link, except for the first link of the chain, the first link being received in a coupling member 16a which is mounted in a cavity in the first slat.
  • the leader slat 2a may have a link member 14 secured thereto which is pivotally received at its lower end in the next link member therebelow, as shown in FIG. 15 and corresponding to the arrangement in US. Patent 2,912,048.
  • Each link 14 is articulated via its closed hook 16 to a member 17 which is embedded in the coresponding slat 2 and secured thereto by a screw 18. Consequently, when one slat, called the leader slat 2a, is tilted, the others all tilt together into the position shown in FIGS. 1 and 13, and when the action on the leader slat 2a ceases, all the slats return simultaneously to their normal position under their own weight, the normal position being the chain-dotted line position in FIGS. 10l2 and 14.
  • the slats 2 are kept in the normal spaced-apart position, visible in FIGS. 10l2 and 14, by their own weight. While these movements are proceeding and at the intermediate stop positions, there is no need to tilt the slats. This need arises when the blind has been lowered with its slats separate from one anothera position hereinafter to be called the spacedclosure positi0n--and more light and/or ventilation is required. To tilt all the slats, it is sufficient to tilt just one slat, since the front chains 13 transmit the tilting movement to all the other slats.
  • the embodiment shown in FIG. 2 comprises means for tilting the top slat 2a hereinafter to be called the leader slat.
  • Projecting from each lateral end of the leader slat 2a is a curved bracket 19 terminating in the pivot 4, and a straight guiding peg 20 which has a substantially triangular cross-section comprising straight sides, a curvilinear base and rounded corners.
  • the bracket 19 and the peg 20 extend from a block 21 embedded in the slat 2a.
  • One of the surfaces of the peg 20 extends substantially parallel with the center-plane of the slat, the latter plane being comprised between the two faces of the slat.
  • the leader slat 2a which is made of sheet-metal, has formed at each lateral end an inwardly bent part 22 which leaves a window or aperture 23.
  • the lower part of the lateral end of the slat is formed with an angular window or aperture 24 at the same level as the aperture 23 and comprising a front portion 24a and a lateral portion 24b.
  • a moving guiding peg 25 is articulated via a flattened end 26 to the inwardly bent part 22 of the slat by a screw 27 and extends outside the slat through the angular aperture 24.
  • the peg 25 can move around the screw 27 in a direction perpendicular to the center-plane of the slat 2a and is cranked in its central portion 25a at the height of the edge 28 of the angular aperture M so that the end 25b of the peg can extend through the portion 24b of the aperture 24 in a direction substantially parallel with the face of the slat 2a. Also, the portion 25a of the peg 25 abuts the edge 28, so that the freedom of movement of the peg 25 is limited by the portion 24a of the aperture 24.
  • resilient means such as a spring 29, for compelling the peg 25 to move laterally into abutting engagement with the edge 28, so that the part 25b projects beyond the side 24b of the aperture 24.
  • a casing 30 is disposed in each of the two lateral guides 3-only one of which is shown in the drawingsat the same height as the leader slat 2a in the spaced-closure position; the casing 30 .comprises a base member 31 and a cover 32 which are appropriately connected to one another and to the guide 3.
  • the guide 3 has a large rib or fin 33, a small rib or fin 34 and a base 35 having longitudinal ribs 36 on its outside surface.
  • the small fin or rib 34 and the portion 34a forming part of the casing 30 form a guiding path for both kinds of guiding pegs.
  • the portion 34a of the rib 34 and an edge 37 of an aperture in the cover 32 of the casing 30 bound a first auxiliary guiding path 38.
  • the vertical guide 3 communicates with the path 38 via a bottom passage 39 and a top passage 40.
  • means for acting on the pegs to urge them into path 38 In order that the pegs 20 (or 25) may engage in the path 38 when the leader slat 2a rises and reaches the bottom passage 39, then goes from the vertical guide 3 to the path 38, there is provided means for acting on the pegs to urge them into path 38.
  • Such means, in the case of peg 25 comprises a spring 29 acting on the movable peg 25.
  • Such means in the case of peg 20 comprises a resilient tongue 41 for acting on the peg 20, the tongue 41 being disposed adjacent the bottom passage 39 as an extension of the portion 34a of the side rib 34 of the vertical guide 3, the tongue 41 extending downwards and away from the alignment of the rib 34 and extending some way into the interior of the vertical guide 3.
  • Adjacent the top passage 40 is a resilient tongue 42 which extends upwardly from the portion 34a into the passage 40, so that the pegs 20 and 25 can pass through said passage 40 when they pass from the path 38 to the guide 3 but not in the opposite direction.
  • the path 38 is extended by a second auxiliary guiding path 43 which extends away from the vertical guide 3; the path 43 is bounded by stationary and/ or moving means for accompanying the pegs 20 (or 25).
  • the stationary accompanying means take the form of an aperture 44 in the cover 32; the top edge 45a of the aperture 44 merges with the edge 37 of the first auxiliary guiding path 38, the aperture 44 lying in a lane which extends parallel with the base 35 of the vertical guides 3 and with the base member 31 of the casing 30.
  • the moving accompanying means take the form of a member 46 which can pivot around the horizontal spindle 47 and which has a hooked part 48 adapted to move between two end positionsa first end position near the place 49 where the second auxiliary guiding path 43 merges with the first auxiliary guiding path 38, and the second end position at the end 50 of the second auxiliary guiding path 43.
  • the pivoted member 46 also has a spring 51 biasing it to the first end position.
  • the casing 30 receives a resilient finger 52 whose free end 53 presses against the portion 34a, forming one boundary of the path 38, at a place 54 higher than the place 49 where the second auxiliary guiding path 43 merges with the first auxiliary guiding path 38. From the place 54 the finger 52 crosses the path 38 downwards and extends to a place Where it is secured to the side of the casing base member 31 by means of a foot 55.
  • FIGS. 10-13 show how the stationary peg type tilting device operates; the non-tilting slats 1, the leader slat 2a and the tilting slats 2 nearest the same are shown in chaindotted lines, while the side guide 3 and the casing 30 are shown in solid lines.
  • the blind is lowered from its rolled or open position (see FIG. 10)
  • the end of the stationary peg 20 slides along the small rib 34 of the vertical guide 3 (see e.g. the position 20a in FIG. 10).
  • the peg 20 passes by the resilient tongue 42, which prevents the peg from entering the first auxiliary guiding path 38, whereafter the peg 20 continues to descend along the portion 34a of the rib 34 (see e.g. the position 20 in FIG. 10), passes by the tongue 41, which prevents the peg 20 from entering the path 38 through the bottom passage 39, and finally reaches a position in which (see e.g., the position 20b in FIG. 10) it abuts the rib 34.
  • the slats cannot therefore tilt while the blind is descending.
  • the peg 20 is soon forced by the strip 41 to enter the bottom passage 39 and thus enter the first auxiliary guiding path 38 until reaching some position therein, for instance the position 20c. If the blind continues to be raised, the peg 20 can leave via the top passage 40, overcoming the force of the strip 42. If the blind is lowered with the peg 20 in its position 20c, the peg 20 moves to a position 20d on the hooked part 48 of the pivoted member 46 (FIG. 12),
  • the peg 20 then entering the second auxiliary guiding path 43 and moving to the end 50 thereof and taking up a position Ziie where the peg 20 is at its furthest distance from the vertical guide 3 (FIG. 13).
  • the leader slat 2a separates a little from the vertical line of the other slats when introduced into the first auxiliary guiding path 38 and is gradually tilted to finally assume a position perpendicuar to such vertical line as it moves along the path 43.
  • the other slats 2 tilt sianeously.
  • the leader slat 2a comprises the moving peg 25 instead of the stationary peg 20, except that the moving-peg embodiment requires no resilient strip 41 (as in FIG. 9) for the bottom passage 39.
  • the pivoted member 46 can be omitted with either kind of peg; if the member 46 is omitted, the aperture 44, not only bounds the path 43, but the edges 45a, 45b of the aperture 44 form the peg-accompanying means, the edge 45a being operative while the blind is being raised from the tilted position to the space-closure position, while the edge 45b is operative while the blind is being lowered, to tilt the slats.
  • the second edge 45b does not act on either kind of peg 20 or 25 when the pivoted member 46 is provided in the casing 30. Thereby, the member 46 serves to permit the passage of peg 20 or 25 in path 43 without contact between the peg and the edges 45a and 45b.
  • the casing 30 receives the resilient finger 52.
  • One function thereof is to guide the peg 20 or 25 towards the path 43, but its main function is to give the rib part 34a a sharp tap or hammerlike blow when the peg 20 or 25 passes from its position intermediate the portion 34a and the free end 53 of the finger 52 (shown in solid-line in FIG. 14) to the immediately higher position (position 200 in FIG. 14), so that an audible warning is given that the peg is in the path 38 and the blind can be lowered to tilt the slats 2.
  • the invention has been described with reference to embodiments used in blinds having inter-engaging, separable and tilting slats but is also of use with blinds whose slats are not inter-engaging.
  • a system for tilting the slats comprising in combination; a movable component comprising a guiding peg at one end of the leader slat near one of the lateral ribs of the corresponding vertical guide means of the blind; a stationary component comprising a first auxiliary guiding path for guiding the peg, such path communicating with the vertical guide means via a bottom passage and via a to passage, the first auxiliary guiding path being disposed near the vertical guide means with a portion of the said lateral rib interposed between the vertical guide means and the first auxiliary guiding path; compelling means which acts on the peg, at least when the leader slat rises and reaches the said bottom passage, to transfer the pe
  • a tilting system as set forth in claim 1 comprising a resilient finger whose free end presses against the said rib portion forming one boundary of the first auxiliary guiding path, the lace where the finger presses against the said rib portion being higher than the place where the second auxiliary guiding path joins the first auxiliary guiding path, the resilient finger being separated at its free end by the passage of the guiding peg when the same moves from the vertical guide means to the first auxiliary guiding path through the bottom passage to produce, by returning abruptly to its stable position, a blow forming an audible signal which warns that the guiding peg is in the first auxiliary guiding path and the blind is ready to be lowered to tilt its slats.
