Definitions

  • the invention relates to a pull up curtain according to the introductory part of claim 1 and to a suspension system of a pull up curtain according to the introductory part of claim 13.
  • pull up curtains are described in which the pull up cords are arranged on one side of the curtain, which side usually forms the backside or outside of the curtain.
  • the operating portions of the pull up curtain are pulled around a side edge of the curtain, causing substantial deformation of a side edge region of the curtain.
  • another curtain is described in which a bundle of portions of cables to be operated is suspended at the front side or inside of the curtain and each pull up cord pass through an individual associated eye in the curtain to the backside or outside of the curtain at which side where it extends vertically downward to the bottom of the curtain.
  • Pull up curtains and suspensions of the initially defined type are known from practice, the curtain as such being typically formed by a web which can be made of various materials, such a woven tissue, non-woven sheets or layered compositions thereof.
  • the web is fixedly suspended and can generally be pulled up by pulling an end of the cords to be operated extending from the pulley-block unit through the hole in the web.
  • the lower end of the web is then pulled up by the opposite end of the cords attached to the web adjacent that lower end.
  • the cords are operated reversely, i.e. veered out.
  • pulled up condition the web material is fan folded, plied into vertically staggered U-shaped plies between subsequent horizontal profiles or randomly tucked up between guide cords or otherwise contracted adjacent the beam. It is also conceivable to roll up the web from the bottom.
  • the web material is generally suspended from the inner side of the beam and particularly from the top or adjacent the top of the inner lateral side of the beam, so also the beam is hidden behind the web material when seen from the inside. From the outside, the beam is generally not visible anyway, because, seen from outside, it is generally hidden behind the window-frame.
  • the pulley-block unit which generally incorporates stopping means, is also positioned at the outside of the web.
  • the pulley-block unit being located at the outside of the web, the cords to be operated for pulling up the web are suspended at the outside of the web, i.e. behind the web when seen from the inside. This would make pulling up and letting down the web cumbersome, because one usually carries out these operations from the inside of the web.
  • the web of the known curtain is provided with an eyelet adjacent the pulley-block unit, through which eyelet the cords are guided.
  • this solutions entails a number of problems.
  • the pulley-block unit incorporates stopping means which retain the cords against release lowering the web if the cords are tensioned in one direction and release the cords when these are tensioned in another direction.
  • the eyelets tend to become dislodged from the web easily, after which the web material adjacent the hole quickly becomes unsightly.
  • this object is achieved by providing a curtain of the initially identified type with the characterizing features of claim 1.
  • the cover in front of the hole in the web is rigidly positioned relative to the pulley-block unit and provided with at least one passage guiding the cord means, any loads exerted onto the boundaries of the passage are directly passed to a rigid structure behind the web, so each cord is reliably guided through the hole in the web material without exerting any forces on the web material itself.
  • the cover with the passage can relatively easily be positioned relative to the pulley-block unit, since the cover is rigidly attached relative to the pulley-block unit behind the web.
  • the cover covers an area of the curtain, so the hole of the web material can be relatively large without appearing visibly.
  • the mounted cover can be used as a jig for determining the position and the shape of the hole in the web material.
  • the invention further provides a suspension of the initially identified type with the characterzing features of claim 13.
  • This suspension is specifically adapted to provide a pull up curtain according to claim 1 after suitably mounting a curtain web thereto.
  • the invention is first described with reference to the pull up curtain shown in Figs. 1-3.
  • the main components of the pull up curtain shown in Figs. 1-3 are a beam 1, a pulley-block unit 2 fixed to the beam 1 and a web 5 fixedly suspended from the beam 1 along the front of the pulley-block unit 2 which is to face indoors.
  • the web 5 is provided with a hole 6 adjacent the pulley-block unit 2.
  • the material of the web 5 is flexible and may for example be sheet material, woven or other textile material or a layered composition of such materials.
  • Cords 3, 4 extend through the pulley-block unit 2 from a horizontal direction essentially parallel to the beam 1 and extend downward from the pulley-block unit 2.
  • Opposite ends 9, 10 of the cords 3, 4 are attached to the web 5 adjacent a lower end of the web 5 so that the lower end of the web 5 is pulled up and let down if the ends 7, 8 of the cords 3, 4 extending downward from the pulley-block unit 2 are pulled respectively veered out.
  • the web 5 is provided with horizontal rods 24 enclosed in loops 25 of the web material.
  • panels 26 of the web material between subsequent rods 24 are each plied into vertically staggered, essentially U-shaped plies or loops between subsequent rods 24. Naturally, the web can also be pulled up partially.
  • the pulley-block unit 2 is provided with a toothed cam 20 for cleating the cords 3, 4, and thereby the lower end of the web 5, in any desired position in a manner generally known in the art.
  • a cover 11 is rigidly positioned relative to the pulley-block unit 2 and provided with two passages 12, 13 guiding the cords 3, 4.
  • the cover 11 is positioned relative to the beam 1 and the pulley-block unit 2 by fastening members 14, 15 which are seated in holes 16, 17 in the pulley-block unit 2 as well as by a flange 18 extending from the cover 11 which is seated against an upper wall of a groove 19 in the beam 1.
  • the cover 11 in front of the hole 6 in the web 5 is fixedly positioned relative to the pulley-block unit 2 and provided with passages 12, 13 guiding the cords, loads exerted by the cords 3, 4 onto the boundaries of the passages 12, 13 are directly passed to the beam 1 and pulley-block unit 2 behind the web 5, so the cords 3, 4 are reliably guided relative to the hole 6 in the web 5 without exerting any forces onto the web material.
  • the cover 11 with the passages 12, 13 can relatively easily be positioned relative to the pulley-block unit 2, since the cover 11 is fixed directly to the rigid structure behind the web 5 which structure is constituted by the beam 1 and the pulley-block unit 2. Furthermore, the cover 11 can simply be dimensioned to cover a relatively large area (e.g.
  • the mounted cover 11 can be used as a jig for determining the position and the shape of the hole 6 in the web material.
  • Each one of the cords 3, 4 cord is guided through a separate passage 12, 13, so twisting of sections of the cords 3, 4 behind the cover 11 is precluded.
  • the passages 12, 13 each have an elongate shape with an essentially uniform width. This allows the angle of the cords 3, 4 relative to the pulley-block unit 2 to be varied between an angle in which the toothed cam 20 engages the cords and an angle in which the cords are not engaged by the toothed cam 20 and can be veered out.
  • the elongate shape of the passages 12, 13 can also be advantageous in combination with other stopping systems which are operated by varying the angle of the end of the cord end extending from the curtain.
  • the cover 11 accommodating the passages can be of a compact design.
  • a suspension system to be used in a curtain according to the present invention may be supplied without web material to lofts and workshops as a base component for manufacturing a curtain according to the invention.
  • the suspension system incorporated in the curtain shown in Figs. 1-3 is constituted by the beam 1 adapted for suspending the web 5 in a plane extending along a lateral face 21 of the beam and the pulley-block unit 2 connected to the beam 1.
  • a divert pulley 23 is rotatably suspended in the pulley-block unit 2 for guiding a cord from a direction essentially transverse to the beam 1 to a direction essentially parallel to and preferably within the beam 1.
  • the pulley-block unit 2 is further provided with a mounting face 22 facing in the same direction as the lateral plane 21 of the beam 1.
  • the cover 11 is adapted to be mounted to the mounting face 21 and the passages 12, 13 are positioned such that, if the cover 11 is in mounted position as shown in Figs. 1 and 3, the passages 12, 13 are closely in front of and below
  • the web 5 When the cover 11 is mounted, the web 5 is sandwiched between the cover 11 and the beam 1. Thus it is ascertained that the web 5 extends directly behind the cover 11, so the hole 6 of the web 5 is not visible, also if one is looking at a small angle relative to the plane in which the web 5 extends.
  • the pins 14, 15 for fixing the cover 11 relative to the beam 1 and the pulley-block unit 2 each extending from the cover 11 through a perforation in the web 5. This enables to support the cover 11 closely to the hole 6 in the web 5 to provide a stable positioning of the cover 11 in the area of the passages 12, 13, also if the hole 6 is located at a substantial distance from the upper end of the web 5.
  • the pin-shaped fastening members 14, 15 are integrally attached to the cover 11. Thus there are no heads of the fastening members 14, 15 which are visible when the cover 11 is mounted. This contributes to the attractive appearance of the cover and avoids the need to provide an additional layer over the cover, such a sticker, to keep fastening members out of sight.
  • FIG. 4 an alternative embodiment of a curtain according to the invention is shown which is provided of which the fastening members 14 are provided with snapping members 26 for reliably retaining the fastening members .14 in mounted position.
  • the curtain shown in Fig. 4 is further provided with a second cover 27 at the side of the web 5 to be facing outdoors and opposite the cover 11. A part of the web material is sandwiched between these covers 11, 27.
  • the second cover is provided with a passage 28 which is positioned and dimensioned such that it is contiguous with the passages 12, 13 in the cover 11 mounted to the side of the web 5 to be facing indoors.
  • the cover 27 provided at the side of the web 5 facing outdoors covers the hole 6 in the web 5 from the outside, so the edges of this hole, which may be crudely cut are also not visible from outdoors if the area of the web 5 including the hole 6 is not hidden behind a window-frame.
  • a suspension system is shown, which represents the presently most preferred embodiment of the invention.
  • the suspension system can be completed into a curtain according to a most preferred embodiment of the invention.
  • the cover is provided with a single passage 12 for the cords, which facilitates assembly into a complete curtain, since all cords can simply be threaded through the same passage 12. If a plurality of cords is passed through the passage 12 and the cords are mutually positioned in a given sequence in longitudinal direction of the passage 12, in practice cords will not easily change places in longitudinal direction of the passage 12, since the passage 12 is so narrow in transverse direction that suitably dimensioned cords threaded through the passage 12 cannot pass each other easily.
  • a rim 29 facing away from the cover 11 is provided in a side of the beam 1 which faces upward when the beam is in its operative position. Furthermore, a hook member 30 is provided which extends transversely from the cover 11 and engages the rim 29. The hook member 30 engaging the rim 29 securely holds the upper end of the cover 11 positioned against the beam 1 and provide additional support against rotation of the cover 11 in the plane in which it extends.
  • the pins of the cover 11 of this embodiment of the invention are also integrally attached to the cover 11.
  • the cover 11 including the hook member 30 and the pins 16, 17 are injection moulded as a single piece.
  • the pulley-block unit 2 of the suspension system shown in Figs. 5 and 6 comprises an upper pulley 23 for diverting cords ends extending within the beam 1 to a direction transversely to the beam 1. From the upper pulley 23, a channel 33 extends downward to a lower pulley 31.
  • the lower pulley 31 cooperates with the toothed cam 20 as a support member against which the cords can be clamped by the toothed cam 20, which is rotatably suspended opposite the lower pulley 31 and guided in grooves (not shown) which extend obliquely in the direction of the channel 33 towards the upper pulley 23 and towards the circumference of the lower pulley 31.
  • the lower pulley operates as a guide pulley guiding the cords form the operated end into the channel 33.
  • a section of the channel 33 adjacent the upper pulley 23 is curved.
  • a cam surface 32 extends in the channel 33 at the inside of the curved section of the channel 33.
  • a brackets 37 are provided for attaching the beam 1 to a horizontal, downward facing surface such as a ceiling.
  • the brackets are somewhat flexible and comprise a hook section 34 and a clip section 35 from which an operating lip 36 extends.
  • To attach the beam 1 to the bracket 37 first one flange of the beam 1 is hooked behind the hook section of the bracket 37. Subsequently, the beam 1 is pivoted about the hook section 34 until the clip section engages a second flange of the beam 1.
  • the bracket 37 is to be mounted with the clip section 35 at its outdoor side.
  • connection formed by the clip section 35 and the flange of the beam 1 engaged thereby does have be adapted to resist some downward force, because the forces exerted onto the cords cause result in a couple about the hook section 34 which urges the flange of the beam 1 engaged by the clip section 35 downward.
  • the suspension system includes a combination of a mounting bracket with a hook section at one side and a clip or snapping section at the other side horizontally spaced from the hook section and a beam from which a web is suspended or to be suspended, the beam being designed so that the plane in which the web is suspended is horizontally spaced from the bracket in a direction in which the side of the bracket where the hook section is located faces.
