Definitions

  • the present invention relates to devices for supporting and driving curtains which can be gathered up along a vertical direction, of the type comprising:
  • a device for supporting and driving a curtain which can be gathered up along the vertical direction and having the above indicated features is disclosed for example in DE-C-4 439 423.
  • the main advantage of the device shown in the prior document lies in that it enables both the removal of the curtain for washing and its mounting on the device upon washing, to be carried out with simple and rapid operations, without the need of introducing again the strips through the guiding passages, this time-consuming and troublesome operation being instead necessary in the more conventional solutions.
  • Each reel is rotated by a driving transmission including a pair of bevel gears and a driving shaft having its axis parallel to the supporting profile of the curtain and connected at one end to a pulley which can be actuated in any known way, for example by a ball chain which drops from above up to a height which can be conveniently reached by the user.
  • a driving transmission including a pair of bevel gears and a driving shaft having its axis parallel to the supporting profile of the curtain and connected at one end to a pulley which can be actuated in any known way, for example by a ball chain which drops from above up to a height which can be conveniently reached by the user.
  • a drawback which takes place with the aforesaid previously proposed curtains lies in that when the curtain is raised, the top guiding passages, arranged at the ends of each horizontal strip run, tend to move closer to each other, thus hindering the raising operation.
  • the present invention provides a device of the type indicated at the beginning of the present description, characterized in that each of said top guiding passages is formed in an element rigidly connected to said supporting profile.
  • each top guiding passage is formed in a supporting body fixed to the supporting profile and having an upwardly facing hook shape, so as to enable an easy disengagement of the strip when the curtain must be removed.
  • each top guiding passage is defined by an eyelet portion of an element releasably connected to the supporting profile.
  • the strip is not removed from the top guiding passages and each of the elements defining these passages is instead removed from the supporting profile.
  • the element defining said eyelet portion is releasably connected to a supporting body which on its turn is fixed to the supporting profile.
  • the top guiding passages cannot move at all towards each other, since they are defined by elements rigidly connected to the supporting profile. Therefore, the raising operation of the curtain may take place in a proper and efficient way. At the same time, easiness and rapidity of removal and mounting of the curtain remain the same.
  • reference numeral 1 generally designates a device for supporting and driving a curtain which can be gathered up along the vertical direction, of the type which has formed the subject of Italian patent application No. TO96A000620 filed on 17 July 1996 by the same Applicant.
  • the device comprises a curtain 1a which can be gathered up on the vertical direction, having an upper edge 2 connected to a supporting metal profile 3 which on its turn can be secured by any known means, for example by screws, to a wall (not shown).
  • the supporting profile 3 is made of a light alloy and has a cross section as clearly shown in the figures.
  • the upper edge 2 of curtain 1a is connected to this supporting profile 3 by quick coupling means, a Velcro (registered trademark) type connection in the illustrated case, provided by two strips 4, 5 (see figures 1, 2) of the type having micro rings and microhooks, respectively fixed to profile 3 and the upper edge 2 of curtain 1a.
  • the lower edge of curtain 1a (not shown) is made heavier by a metal blade and is supported by one or more pairs of vertical supporting strips 6, 7.
  • the right hand vertical strip 7 is shown of a first pair of strips (the associated left hand strip is not visible in the drawing) along with a left hand vertical strip 6 of a further pair of vertical strips 6, 7 (the associated right hand strip being not shown in the drawing).
  • Each pair of vertical strips 6, 7 have their lower ends (not shown in the drawings) rigidly connected to curtain 1a adjacent to the lower edge thereof and are guided through guiding passages 8 (one of which is visible in figure 1) formed in curtain 1a.
  • the two vertical strip runs 6, 7 of each pair are directed at the top through guiding passages 9 which, according to the invention, are formed in elements rigidly connected to the supporting profile 3, the two vertical runs being connected to each other by a horizontal strip run 10, so that the vertical runs 6, 7 and the horizontal run 10 form a general upturned U-shaped configuration.
  • Each reel 12 is rotatably mounted around an axis 12a perpendicular to the plane of curtain 1 (figure 1) by a supporting bracket 13 fixed to the supporting profile 3.
  • Each reel 12 can be rotated by a respective pair of bevel gears (not shown) meshing with each other and arranged within a housing 13a fixed to the bracket 13 and respectively connected to reel 12 and a shaft 16 having a square cross section and an axis parallel to the supporting profile 3, this shaft being rotatably supported by the brackets 13 which also support reels 12, as well as by two end brackets (not shown in the drawings) fixed to the supporting profile 3.
  • a driving pulley (not shown) which can be rotated by a ball chain which drops downwardly up to a height which can be conveniently reached by the user.
  • each reel 12 has a front face 17 entirely crossed by a diametrical slot 18 which is adapted to receive a central portion of the respective horizontal strip run 10. In this manner, when reel 12 (figure 1) is rotated, the two halves of the horizontal run 10 arranged at the two sides of reel 12 are wound on reel 12.
  • curtain 1a must be removed for washing, it is sufficient to disengage each horizontal run 10 from the respective winding reel 12, simply by disengaging the central portion of the horizontal run 10 from the respective slot 18. Then, by separating the upper edge 2 of the curtain 1a from the supporting profile 3 it is possible to remove completely the curtain 1a, while the vertical supporting strips 6, 7 cannot slip out of the guiding passages 8, since they are held by the respective horizontal runs 10.
  • each top guiding passage 9 is defined by an element having an upwardly facing hook configuration, so as to enable easy removal of the strip therefrom when the curtain 1a is removed.
  • the element defining the top guiding passage 9 is rigidly connected to a supporting body 19 which projects downwardly from the supporting profile 3 and is fixed thereto by coupling means of any known type.
  • body 19 has a top head 19a (figure 2) having a T-shaped cross section, which is slidably received within a lower slot 3a of profile 3 and is locked axially within this slot by rotating a cam 19b which is rotatably supported around a vertical axis 19c by head 19a and can be rotated by a control lever 19d between an unlocking position and a locking position.
  • This locking device however is of a type known per se and does not fall, taken alone, within the scope of the invention.
  • any other known coupling means can be used for connecting body 19 to profile 3.
  • a further feature of the preferred embodiment shown in figures 1, 2 lies in that the element defining the top guiding passage 9 associated with a right hand vertical strip run 7 and the element defining the top guiding passage 9 associated with the adjacent left hand vertical strip run 6 are rigidly supported by the same supporting body 19.
  • Figures 4, 5 show a variant in which the element defining each top guiding passage 9, which has an upwardly facing hook configuration, is carried by a respective supporting body 19 and in which the latter has a wall 19e having an edge 19f adjacent to the top of the hook portion, so as to decrease the risk of an accidental disengagement of the strip from the hook portion.
  • Figures 6-9 show a second embodiment of the invention in which the element defining each top guiding passage 9 has an eyelet portion.
  • the element defining each top guiding passage 9 has a body including a pair of parallel and spaced apart cylindrical element 20 extending between two parallel plates 21, one of which is provided with a stem 22 which is releasably received within a cylindrical hole 23 of the supporting body 19.
  • the two cylindrical elements 20 and the two plates 21 thus define an eyelet which is engaged by a vertical right hand run 7 of a pair of vertical runs 6, 7 as well as by the adjacent left hand vertical run 6 of the adjacent pair of vertical strips 6, 7.
  • Stem 22 has a notched portion 22a adapted to cooperate with a rib 24 formed in the wall of hole 23 to provide a pressure snap engagement of element 9 on supporting body 19.
  • a sufficient force to element 9 it is possible to obtain removal thereof from body 19, due to a deformation of the wall of body 19 with rib 24. Therefore, also in this case it is possible to provide rapidly for the removal of curtain 1a.
  • the strips 6, 7 remain engaged through the eyelet formed by the passage defining element and the latter is instead removed from the supporting profile 3.
  • any other quick coupling means between the element defining the top guiding passage 9 and the supporting profile 3 may be used.
  • the supporting body 19 on its turn is connected to the supporting profile 3 in a way identical to that already described for the first embodiment.
  • the invention is applicable not only to the solution which has formed the subject of the previous Italian patent application of the Applicant, but also generally to any other type of gather-up curtain, and particularly to a curtain of the type shown in German patent DE-C-4 439 423.
  • the device according to the invention enables all the advantages of the previously proposed curtains which have been described above to be kept, with reference to easiness and rapidity of the operations for removing and mounting the curtain, while ensuring that during raising of the curtain the top guiding passages 9 remain at fixed positions, so as to provide for a proper and efficient raising operation.
  • the supporting bodies 19 may be shaped in such a way that the top guiding passages 9 are formed in the same plan parallel to curtain 1a and containing the front slot 18 of reels 17, so that the horizontal strip runs 10 are oriented exactly parallel to the supporting profile 3, differently from what may take place in the previous solutions in which the top guiding passages 9 are formed in curtain 1a, which involves that the horizontal strip runs 10 are arranged slightly inclined relative to the plane of curtain 1a.
  • cords or any other equivalent means may be used instead of the above described strips.
