Definitions

  • the invention relates to a shirring device for raising and lowering a shirring curtain with shirred rollers arranged distributed over the horizontal length of the curtain, which are provided with rollable pulling elements for raising and lowering the shirring curtain and by a common drive element around them Roll axes are rotatable.
  • a device for lifting and lowering a venetian blind is known from DE-OS 33 05 300.
  • This device consists of shirring rollers spaced apart from one another over the horizontal length of the curtain.
  • the raffle rollers are attached to a curtain rail, for example, by means of bearing blocks.
  • the axes of the shirring rollers run in the longitudinal direction of the curtain or curtain rail. All rollers are arranged in a torsion-proof manner on a winding shaft which is mounted in the bearing blocks and is guided to a longitudinal end of the curtain.
  • At one longitudinal end of the curtain there is an elevator roll, the axis of which is aligned with the winding shaft.
  • the elevator roller can be equipped, for example, with a cord, preferably a ball cord, which hangs down from the elevator roller into the area which can be reached by the operator.
  • a cord preferably a ball cord
  • Such an elevator device consisting made of winding roll and cord, can also be replaced by a drive motor that acts directly on the winding shaft.
  • the object is achieved in that -
  • the roll axes of the Raff rolls in the ceiling area run transversely to the longitudinal direction of the curtain, - the shirring rollers are connected in a torsion-proof manner to coaxial drive rollers to form roller sets, - the roller sets can be set without rigid mutual connection, -
  • the drive rollers of the rope or chain-like winding drive member, which is continued from drive roller to drive roller, are rotatable.
  • the main advantage of this device is based on the arrangement of the roller axes perpendicular to the longitudinal direction of the curtain. In this way, it becomes possible to change from the previously usual rigid winding shaft to a winding-capable drive member. This leaves the rigid connection between the individual Raff rolls.
  • a drive roller is connected coaxially to each shirring roller, and the windable drive member is now looped over this drive roller.
  • the wrapping of the respective drive roller is pulled from drive roller to drive roller up to the drive roller furthest away from the end of the pull.
  • This drive roller can take up the full train length on itself when the venetian blind is fully lowered. If the curtain is pulled up, the drive member rolls off this drive roller and falls to the side of the curtain, for example. But it can also be rewound on the train side. For example, when the curtain is raised and lowered along the curtain, the drive member is pulled once in one direction and once in the other direction.
  • a deflection device is provided, by means of which the drive member can be deflected in the lifting and lowering direction of the curtain that the horizontally acting, windable drive member between the shirring rollers by means of the deflection device is suspended below, the part hanging down serving as an actuating part.
  • the drive rollers are provided with dome-shaped recesses for ball cords or with serrations for chain bands or with wedge guides or adhesive surfaces for cords, either wrapping or tangential contacting of the drive rollers being provided.
  • other drive means are also conceivable. For a simple configuration, it is only necessary that the individual drive rollers are operated safely together.
  • a plurality of shirring rollers are arranged so that they cannot rotate against one another, but can be rotated together, with one drive roller each.
  • the curtain design can be made much more complex and thus more interesting. If several curtains hang in a row, then one curtain can be gathered with one roll of a set of rollers and the other curtain can be gathered with the other roll of the set of rolls. Of course, different raff heights are also conceivable.
  • the drive rollers can be plugged onto the gathering rollers.
  • drive rollers of the desired type can be combined with the gathering rollers.
  • the roller sets consisting of at least one shirred film and the drive roller, are arranged in a housing which can be closed by means of a cover. By arranging the roller sets in the housings, they are protected from dust and have an attractive appearance.
  • the roller axles or the housings which hold the roller sets can be attached to a curtain rail. The individual housings can either be slipped on top of the curtain rail or clicked onto it. Locking at the desired point on the curtain rail prevents slipping.
  • the deflection device consists of a separately mounted single roller, by means of which the drive slide which is guided to the drive rollers is deflected downward. With such a single deflection roller, the drive member is only suspended downwards and partially falls on the floor.
  • an additional drive roller is provided with a winding roller that is rotatable relative to it between the single deflection roller and the first driving roller, the drive member simultaneously pulling the winding roller with the gathering rollers when pulling the curtain rotates and its downward hanging part is lifted up from the winding reel to form a pull loop and wound up.
  • the single deflection roller lets the drive member hang down, it winds up the winding roller at the same time, forming a low-hanging loop. In this case, no part of the Drive link to the floor.
  • Another advantage is that you can always pull down. If the Raff curtain is to be raised, the part of the drive element that hangs from the single deflection roller is pulled downwards. If the Raff curtain is to be lowered, the part of the drive element hanging from the winding roller is pulled.
  • manual operation can also be replaced by motor operation if, for example, according to a further embodiment of the invention, the first drive roller or an upstream additional drive roller can be driven by means of an electric motor.
  • Fig. L shows in section a wall or the lintel l of a building, not shown, in front of or in front of which a curtain 3 is suspended.
  • roller sets 7 are arranged in housings.
  • the housing 5 are, as can be seen particularly clearly from FIG. 4, provided with bearing block-like suspension heads 9, which can be pushed or clipped onto a T-shaped curtain rail, for example.
  • the roller sets consist of two rollers which are rotatable about a roller axis 11 and are connected to one another in a rotationally fixed manner.
  • a roller 7a represents a gathering roller and a roller 7b a driving roller. Both rollers can be designed in one piece or pluggable together.
  • a number of roller sets 7 arranged in housings 5 are required for the gathering of a gathering curtain.
  • the two roller sets shown on the left can be thought of as the first and last shirring roller set, between which several roller sets are distributed. This is indicated by the break line l3.
  • the housing 5 and the roller sets 7 are shown opened from the front.
  • the curtain rail 15 into which the suspension heads 9 of the housings are inserted can be seen above the housings.
  • the shirring tapes l7 are guided on the shirring curtain by means of loops l9.
  • the shirring tapes 17 are arranged on the shirring rollers 7a and are rolled off the shirring rollers when the shirring curtain 3 is lowered.
  • a windable drive member 2l which can be a cord, a ball cord, a chain belt or the like, is operated by the deflection device 23 shown on the right in FIGS. If the Raff curtain 3 is lowered, the drive member 2l is released by the deflection device 23 and it moves in the direction of an arrow 25 to the left.
  • the deflector is at least once around Drive roller 7b of the first roller set 7.l looped and leads over the further roller sets to the roller set 7.n. There it is wound up when the Raff curtain 3 is lowered. Appropriate dimensioning of the winding core of the drive roller 7b of the roller set 7.n ensures that all drive rollers 7b rotate at the same speed.
  • the venetian blind 3 is thus lowered evenly over the venetian belts l7.
  • the curtain 3 is raised, the direction of pull of the drive member 2l reverses. To raise the tieback 3, the drive member is thus pulled in the direction of an arrow 27 toward the deflection device 23.
  • the deflection device 23 consists, for example, of a roller set 7.0, which can correspond to the roller sets 7.l to 7.n.
  • a single deflection roller 29 is provided.
  • the cord-like or chain-shaped drive member 2l wraps around the drive roller 7b and is then passed on to the deflection roller 29, from which it then hangs vertically downward. The end of the drive member is then raised again via a loop 30 and wound onto a shirring roller 7a.
  • the operator pulls the part 2la of the drive member 2l downward.
  • the drive member 2l then moves in the direction of arrow 25 and rotates the roller sets 7.l to 7.n in the rolling sense for the gathering belts l7.
  • the curtain 3 is to be raised, the operator pulls the part 2lb of the drive member 2l. Now the drive rollers 7b for the gathering belts l7 in winding sense turned, and the Raff curtain 3 rises.
  • Fig. L only one drive roller 7b is shown in the dash-dotted housing box.
  • This drive roller 7b is operated by means of an electric motor 32 via a shaft 3l. With the aid of the electric drive, the drive member 2l is pulled back and forth between the roller 7b, on which the motor 32 acts, and the roller 7b of the roller set 7.n, in order to lower and raise the curtain.
  • FIGS. 3b, 3d and 3f show suitable drive elements.
  • 3a, 3c and 3e the gathering rollers 7a are designed in the same way.
  • Different drive roller types 7b.l, 7b.2 and 7b.3 are attached to them.
  • the drive roller 7b.l has a ring of calottes 33
  • the drive roller 7b.2 a ring with teeth 35
  • the drive roller 7b.3 is designed as a wedge disc with a V-shaped trough 37.
  • a ball cord 2l.l is used, into which a distance the spherical caps 33 balls 34 are incorporated, as can be seen from FIG. 3b.
  • a chain belt 2l.2 with openings 36 which can be seen in FIG. 3d, is used.
  • a cord 2l.3 shown in FIG. 3f is used to actuate the drive rollers 7b.3 in the form of a wedge disk.
  • Other transmission means are of course also conceivable, as can be seen, for example, from FIG. 5, where the drive roller 7b.4 is designed similarly to a shirring roller 7a and has 38 adhesive strips 39 on its winding core 38 in the form of a slight Velcro or adhesive adhesion.
  • Fig. 4 shows in section a housing 5 which receives a roller set 7.
  • the housing corresponds to that of FIGS. 1 and 2 and has a suspension head 9 which can be clamped onto a T-rail.
  • the suspension head can also be designed for insertion into a U-rail.
  • the housing 5 is provided on its front with a cover 6, which is attached.
  • the housing 5 with suspension head 8 and the cover 6 are preferably plastic injection molded parts.
  • FIG. 5 shows a further variant, with which it is possible to design venetian blinds in an even more varied manner, such as, for example, constructing them from a plurality of individual curtains hanging from one another.
  • a roller set 7 ⁇ is inserted into the housing 5 ⁇ according to FIG Drive roller 7b.4 and two laterally non-rotatably attached shirring rollers 7a.
  • the roller set 7 ⁇ is guided in the housing 5 ⁇ via a roller axis 11 ⁇ .
  • a suspension head 9 ⁇ on the housing 5 ⁇ is adapted to a special type of T-curtain rail l5 ⁇ .
  • the Raff curtain 3 is raised and lowered via the Raff tape 17, which is only indicated as a double arrow.
  • Raff curtain 3 ⁇ which hangs in front of the Raff curtain 3, is operated with the help of Raff tapes l7 ⁇ the front Raff roll 7a.
  • the Raff tapes l7 and l7aff in loops l9 and l9 ⁇ are indicated on the Raff curtains 3 and 3 ⁇ .
  • clamping screws 4l are provided which press against the T-rails l5 and l5 ⁇ from the suspension heads 9 and 9 ⁇ .
  • the roller sets 7 and 7 ⁇ in the housings 5 and 5 ⁇ are provided with a self-locking if necessary.
