Definitions

  • the present invention relates to devices for supporting and controlling roller blinds.
  • the object of the present invention is that of providing a device of the above indicated type which is relatively simple and reliable while enabling the user to control lowering and raising of the blind with easy and rapid operations.
  • the invention provides a device for supporting and controlling a roller blind, having the features indicated in the annexed claim 1.
  • reference numeral 1 generally designates a roller blind comprising a blind web 2 having a lower edge strengthened by a a bar 3 and an upper edge (not visible in the drawings) anchored to a roller 4 for winding the web which is rotatably supported around a horizontal axis 5 by a fixed support structure 6 (figure 1).
  • the fixed support structure 6 includes a metal profile 7 (see for example figures 4, 5) which is to be anchored by any known fixing means to a ceiling 8 or a wall, for example above a window aperture which blind 1 is to cover.
  • the fixed support structure 6 includes two end heads 9, 10 (figure 1) which rotatably support the two ends of roller 4 respectively.
  • the end head 9a comprises a housing of plastic material 9a, including a front wall 11 and two side walls 12, as well as an upper wall 13 (figure 9).
  • the housing 9a of plastic material has its upper portion fitted inside the profile 7 (figure 9).
  • the end head 9 further includes a body of plastic material 14 which has two vertical side arms 15 which are elastically deformable, and end with end teeth 16 adapted to be engaged by snap action each within a window 17 of the cooperating side wall 12 of the housing 9a. In this manner, the body 14 may be snap mounted into housing 9a once this body has received the respective end of the roller 4 of the blind, to the advantage of convenience of assembling of the device.
  • roller 4 has a tubular body which, at its end facing towards head 9 (the end on the left in figure 1) which rotatably supports a disk 18 at its inside which is connected to the conventional spring which biasses the roller towards the position of complete winding of web 2.
  • This spring is not shown in the annexed drawings, since it may be made in any known type and it does not fall, taken alone, within the scope of the present invention.
  • the roller 4 rotates (in an anticlockwise direction with reference to figures 5, 9) causing the loading of said spring, which therefore is able to return the web to its raised position when it is no longer locked in a lowered condition.
  • disk 18 is provided with an axial tab 19 projecting outwardly which is kept locked on head 9 in a way which will be described after, in order to enable said return spring to be loaded when the blind web is lowered.
  • the anchoring angular position of tab 19 on head 9 is adjustable, in order to allow for an adjustment of the load of the return spring located inside roller 4.
  • tab 19 is received in an axial slot 20 of a circular disk 21 having a central cylindrical pin 22 which is freely rotatably received within a circular through hole 23 of the body 14 of plastic material and is axially retained therein by an elastic ring 24.
  • Disk 21 is further provided with a cylindrical skirt 25 surrounding the central pin 22 and interrupted at one portion so as to define two radial stop surfaces 26, 27.
  • this body has a projecting annular edge 28 which defines said through hole 23.
  • a helical spring coupling 29 formed by a helical spring which is tightened by its elastic load around the edge 28 and has two end tails 30, 31 projecting radially at the area wherein the skirt 25 is interrupted.
  • the hub 32 of a circular knob 33 having a knurled gripping peripheral surface 34.
  • the hub 32 of knob 34 has an inner radial tooth 35 which radially projects inside the area in which the skirt 25 is interrupted, between the two end tails 30, 31 of spring 29.
  • the knob 33 serves for adjusting the load of the return spring means of roller 4.
  • tab 19 connected to the return spring located inside roller 4 is kept in a fixed position with respect to the end head 9.
  • this rotation cannot be followed by disk 18 and tab 19, since the latter is rotatably connected to disk 21 and disk 21 cannot rotate since abutment surface 27 impinges against the end tail 31 of spring 29 which is tightened around the edge 28 of body 14 (fixed) and therefore prevents a rotation of disk 21.
  • the device is able on one hand to rotatably support one end (that on the left with reference to figure 1) of the blind roller and on the other hand to allow for load of the spring biassing the roller towards the position of complete winding of web 2 of the blind to be adjusted.
  • roller 4 of the blind has inside a first tubular body 36 of plastic material.
  • Body 36 has outer longitudinal wings 37 (figures 3, 4) which are received with an interference fit within roller 4 (figure 2) to connect permanently in rotation the first tubular body 36 to roller 4.
  • the first tubular body 36 is rotatably supported around axis 5, in a way which will become apparent in the following, on a second fixed tubular body 38 (figures 2, 4) forming part of the end head 10 of the fixed support structure 6. More precisely, the first tubular body 36 is rotatably mounted on the second tubular body 38 with the interposition of a third tubular body 39 (figures 2, 4), which will be illustrated in detail in the following.
  • the end head 10 forming part of the fixed support structure 6 also includes a housing of plastic material 40 which has its upper part (figures 6-8) fitted within profile 7.
  • the housing 40 has a centrifugal mass brake 41 inside (shown only diagrammatically in figure 2) which can be made in any known way and does not fall, taken alone, within the scope of the present invention.
  • brake 41 is for slowing down the rotation of roller 4 when the latter returns towards its position of complete winding of the blind web due to its return spring means.
  • the housing 40 has a central mouth 42 from which there extends a rotatable hexagonal shaft 43 connected in rotation to brake 41.
  • Shaft 43 is received into an hexagonal cavity 44 (figure 2) formed at one end of a shaft 45 (figures 2, 4) which is freely rotatably mounted within the tubular body 36 and at its opposite end has two deflectable tapered axial wings 46 to receive and lock by a snap action a bush 47 thereon which is received inside the end of the tubular body 36 facing towards the inside of blind roller 4.
  • Bush 47 is normally tightened within the coils of a helical spring coupling 48 having a radial end tail 49 received in a longitudinal slot 50 (figures 2, 4) of the tubular body 36.
  • the coupling 48 is for connecting the centrifugal mass brake 41 to the blind roller when the latter is returned by its return spring means towards the raised position of web 2 and to discontinue this connection when the web is lowered, so as to avoid that brake 41 renders this operation more difficult.
  • roller 4 rotates in an anticlockwise direction (with reference to figures 3, 4 and 6-8).
  • the slot 50 of tubular body 36 actuates the end tail 49 of spring 48 so as to open the coils of the latter to cause a free rotation thereon around bush 47. Therefore, in this condition, the rotation of the roller is not transmitted to the centrifugal mass brake.
  • the roller is caused to rotate in the opposite direction (i.e.
  • the third tubular body 39 has an intermediate disk 51 from which there project two opposite tubular portions 52, 53.
  • disk 51 is further provided with a cylindrical skirt 54 coaxially surrounding the tubular portion 53 and having an interruption so as to define radial abutment surfaces 55, 56 (figures 4, 6).
  • Disk 51 further pivotally supports, by means of a radial pin 57, a rocking lever 58 having ends 58a, 58b projecting from opposite sides of disk 51 through an aperture thereof.
  • disk 51 On the side facing towards roller 4, disk 51 further has an axial wing 59 (figures 4, 7).
  • tubular portion 53 of tubular body 39 is freely rotatably mounted within the second tubular body 38.
  • tubular portion 52 is freely rotatably mounted within the first tubular body 36.
  • a one-way helical spring coupling 60 is tightened which is formed by a helical spring which is tightened by its elastic load on the tubular body 38 and has an end radial tail 61.
  • This tail is arranged in the area in which the cylindrical skirt 54 of tubular body 39 is interrupted (see also figure 6).
  • the tubular body 36 has an end portion 36a facing towards the end head 10 on which a helical spring coupling 62 is tightened having end radial tails 63, 64.
  • coupling 62 serves to normally connect in rotation tubular body 36 to tubular body 39, while discontinuing this connection during the winding stage of the blind web.
  • Coupling 60 serves to keep the blind roller 4 locked over the fixed tubular body 38, by means of the interposition of the tubular body 36 and the tubular body 39, when the blind web must be stopped in any partially or totally lowered position. The detailed operation of these couplings will be described later.
  • the fixed tubular body 38 forms part of a plate 65 of plastic material which is fixed to the housing 40 by a snap action as well as with the aid of a screw 66 (figure 2).
  • a driving pulley 67 (figure 4) which is rotatably mounted on the tubular body 39 (figure 2) and can be engaged by a flexible driving member 68, which in the illustrated example is formed by a chain of balls 69 adapted to engage seats 70 formed on the periphery of pulley 67.
  • the ball chain 68 has two vertical runs 71, 72 which extend sufficiently downwardly to enable the user to operate the blind easily; these runs are to be pulled downwardly to cause the progressive lowering or the rapid raising of the blind web 2 respectively.
  • the driving pulley 67 has an inner radial tooth 73 which is arranged (figure 6) between the radial tail 61 of spring 60 and the end 58b of the rocking lever 58.
  • the ends 58b and 58a of the rocking lever are for cooperation with the radial tooth 73 of the driving pulley 67 and the tail 64 of spring 62 respectively in order that when the run 72 of chain 68 is pulled, in order to cause the rapid raising of the blind web 2, the tooth 73 rotates the rocking lever 58 so as to cause an opening of spring 62.
  • tubular body 39 The rotation of tubular body 39 is on its turn transmitted by the axial wing 59 to the tail 63 of spring 62 (figures 4 and 7) which is tightened around the portion 36a of the tubular body 36 and therefore transmits its rotation to said tubular body and consequently to the blind roller 4.
  • the roller is caused to rotate in an anticlockwise direction, with reference to figures 6-8, causing thereby the lowering of the web 2 of the blind.
  • the blind Once the blind has been locked in any partially or completely lowered position, it may be unlocked to cause a rapid return of web 2 to the raised condition by pulling the run 72 of chain 68. A short pulling action imparted to this run is sufficient to cause the engagement of the tooth 73, as already discussed, against the end 58b of the rocking lever 58. This rocking lever is thus compelled to rotate so as to bring its opposite end 58a against the tail 64 of spring 62 which is thus opened discontinuing the rigid connection between the tubular body 36 (connected to the blind roller) and the tubular body 39 (locked by spring 60 on the fixed tubular body 38). The tubular body 36 is therefore free to rotate inside the coils of spring 62, along with roller 4, under the action of the return spring means of the latter. In this manner, the web 2 is rapidly wound on roller 4.
  • the slot 50 causes an opening of the coils of spring 48 so as to discontinue the connection between the centrifugal mass brake 41 and the blind roller.
  • the tubular body 36 rotates in the direction tending to tighten the coils of spring 48 over the push 47. Therefore, in this condition, roller 4 is connected in rotation to the centrifugal mass brake 41, that slows down the roller during the winding stage.
  • the device according to the invention enables the user to control the blind with very simple, convenient and rapid operations.
  • it has a relatively simple and reliable structure.
  • the possibility to adjust the load of the return spring means for the roller provided by the device illustrated in figure 5 renders the invention further advantageous.
  • the possibility to snap engage the body 14 into the housing 10 following its coupling with roller 4 renders the assembling operation of the blind particularly simple.
