Definitions

  • the invention relates to a curtain rail with a cord and longitudinally displaceable curtain carriers, with the traction elements connected to the curtain touching the cord and being removable from the cord when the cord is actuated due to the static friction.
  • the device In addition to the curtain carriers, which are loosely lined up on the cord, the device has driver disks, which are also penetrated by the cord.
  • the curtain is attached to the curtain brackets by means of chains. Each holding chain is assigned a somewhat longer pull chain that connects the curtain to the drive plates.
  • the disks When the cord pull is actuated, the disks are first taken along a short distance by the cord due to the static friction, whereby they are inclined together with the stretching pull chains. As a result, the disks jam on the cord, so that the curtain is also pulled when the cord is moved further.
  • the cord can slip relative to them.
  • the device is used in particular to apply a uniform tensile force to heavy curtains and to prevent the formation of creases outside the end zones of the curtain.
  • the inclinable pull chains with the washers should also stabilize the curtain and make it impossible to swing.
  • the known device has a complicated structure and is not suitable for light, short curtains, such as those used in hotels and public buildings. Such curtains are often operated by different people, some of whom are used to flinging the curtains and others who prefer the pull cord type. For example, it is common in the USA to put curtains on the curtains, while the European generally prefers curtains for slinging.
  • the curtains are often not operated carefully, so that with known curtains with a drawstring there is often the risk that overloads lead to the curtains being torn out. This is particularly the case if the curtains are closed and opened by pulling directly on the free curtain ends instead of using the drawstring.
  • curtain rails which are connected to the pull cord and pull the curtain when the last one is actuated. If there is too much tension on the cord or on the curtain, the connection of the cord with the followers can tear or the entire rail can be torn down.
  • the assembly and adjustment of curtains with forerunners is complex.
  • the forerunners must be precisely positioned and coordinated, otherwise the curtain will not close or open completely.
  • To position the precursors on the line the distance must be removed before the rail is installed on the line. The readjustment of the forerunners after the rail assembly is difficult and connected with operations.
  • a pulling device for curtains in which individual curtain carriers are designed as intermediate carriers and have rollers that run on the pull cord. To center the pull cord and to prevent the curtain brackets from tilting, the cord is guided through the center of the rollers.
  • the intermediate carriers which are only held by the cord and are not supported on the rail, hang down, which is disadvantageous. To reduce the deflection somewhat, the pull cord is stretched using a heavy counterweight. It is also disadvantageous that, when the curtain is closed, the pull cord is not guided at all over a long distance and, despite the stretching, also hangs down here.
  • the pull cord To operate this curtain, the pull cord must be attached to a carrier or a main curtain support, otherwise it would simply be pulled under the slightly rotating rollers without moving the curtain.
  • the assembly of this pulling device is complex since the pull cord has to be threaded into each curtain support.
  • the invention now has for its object to provide a curtain rail with a cord of the type mentioned, in which the disadvantages of the known devices are avoided.
  • the curtain rail with drawstring should have fewer items, so that it is cheaper to manufacture.
  • the assembly should be simple and the operation should be comfortable and uncomplicated, both with the cord pull as well as with a blasting stick or by manually pulling on the free curtain ends.
  • it should be possible to drive a z. B. to provide an electric drive that brings no difficulty with regard to the setting of limit switches.
  • the curtain rail should be able to be assembled telescopically from individual rail parts without the bumps affecting the movement of the running elements.
  • the object is achieved in such a way that the curtain carriers themselves are designed as tension elements, that the cord is guided in the longitudinal direction through at least one longitudinal channel of the curtain rail, that the curtain carriers are supported indirectly via the cord on the rail, and that when the Static friction loops the cord relative to the curtain carriers.
  • the curtain rail consists of telescoping rail parts.
  • Extendable curtain rails are well known, e.g. B. from DE-C 747 108.
  • the known curtain carriers rolling on the rails experience a blow at the step-like transition point, which is very disadvantageous.
  • curtain carriers are only in contact with the cord covering the transition point, no more blows can occur.
  • the profile of the curtain rail 1 according to the F i g. and 2 is composed of two symmetrically arranged longitudinal channels 2, 3 for the cord 4 and the running elements 5, 5a and a fastening channel 6, in which known plastic buttons, not shown, can be retracted, around the curtain rail 1 on the wall to assemble.
  • a continuous intermediate web 7 separates the fastening channel 6 from the longitudinal channels 2, 3.
  • Each longitudinal channel 2, 3 is composed of a lower groove-shaped part 8, 9 and an upper groove-shaped part 10, 11 with a U-cross section.
  • a deflection roller 13 is mounted at one end 12 of the curtain rail 1 and two exit rollers 14, 17 are rotatably attached to the opposite end 16.
  • the endlessly woven cord 15 of the cord 4 passes from the one exit roller 17 into the one longitudinal channel 2, from there to the deflection roller 13 and then back again into the other longitudinal channel 3 to the second exit roller 14.
  • the operating part of the cord 4 hanging down is through that Weight 18 weighed, with a further deflection roller 19 for the cord 15 being mounted in the weight 18.
  • the cord 15 lies in the channel-shaped parts 8, 9 of the longitudinal channels 2, 3 and is guided through them.
  • the running elements 5, 5a which are made in one piece from plastic, are guided so that they can move longitudinally in the longitudinal channels 2, 3, namely one group 5 is assigned to the inner longitudinal channel 3 and the other group 5a to the outer longitudinal channel 2.
  • a lower part 20 of the running elements 5, 5a protrudes downward out of the curtain rail 1 through the space 22 arranged between the two channels 8, 9 and is provided with a recess 21 to which the curtain is fastened.
  • a round pin 23 is also attached, which rests on the cord 15 and is pressed against it by gravity.
  • the pin 23 is guided through the groove 10, 11 of the longitudinal channel 2, 3 and connected via the neck 24 to a central part 25 of the barrel element.
  • the pin is in frictional contact with the cord.
  • the round shape ensures that there is always a point-like contact point even when the curtain swings slightly, so that the frictional force is always the same.
  • the two curtains are each fastened to one end 12 or 16 of the curtain rail 1 and suspended in the running elements 5, 5a. If the cord 4 is now actuated, the two groups 5, 5a of running elements are displaced towards one another by the cord 15 against the middle of the curtain rail 1. As soon as the curtain fold between the rail end and the first running element is pulled out, remains are the first running element and the cord 15 grinds under its round pin 23. This process is repeated until all running elements stand still and the two free curtain ends touch. If the cord 4 is pulled further, there is no danger that the curtain or the cord will be injured, since the cord is simply pulled under the pin 23 with sliding friction. When opening the curtain, the sliding elements are moved against the ends of the curtain rail until they line up, in which case the cord loops again.
  • the curtain can also be used without a cord, e.g. B. by a flinging rod, a centrifugal cord or simply by hand by pulling on the free curtain ends. Then the running elements slide on the stationary cord until the curtain is closed or opened.
  • a cord e.g. B. by a flinging rod, a centrifugal cord or simply by hand by pulling on the free curtain ends. Then the running elements slide on the stationary cord until the curtain is closed or opened.
  • the curtain rail 26 of FIG. 3 differs from that of FIG. 1 and 2 in that the fastening channel 6 is not arranged laterally but at the top, and in that the space 22 between the two channels 8, 9 is wider. So it is possible that the running elements 5, 5a mounted in the two running channels 2, 3 are moved next to each other in the area of the free curtain ends can so that the curtain closes better due to the covering.
  • the other ends of the curtain parts are hung on the rail ends by means of brackets (not shown).
  • a two-part curtain rail 27 made of rolled iron sheet is shown.
  • the surface can be treated, for example, by stove enamelling.
  • Rolled curtain rails can be produced with tighter tolerances compared to extruded light metal curtain rails, which is particularly advantageous when telescoping the two curtain parts 27a, 27b.
  • the butt joint 28 present between the two rail parts 27a, 27b does not interfere, since it is bridged by the cord 15.
  • the running elements 5, 5a are arranged above the cord 15 and do not slide directly on the rail.
  • the rail 29 has only a single running channel 20 in which the running elements 5 are guided.
  • a deflecting roller 13 or two exit rollers 14, 17 are provided on the rail ends, so that the cord pull 4 can only be operated from one side.
  • both rail ends are each provided with an exit roller 31, 32. This curtain can be operated from both sides. In contrast to the other devices, the cord is not made endlessly here.
  • the curtain device according to the invention is particularly suitable for an electric drive, for. B. one of the rollers is driven.
  • an electric drive for. B. one of the rollers is driven.
  • only a cheap pulse switch is required.
  • the curtain is self-adjusting with an electric cable and can also be easily installed by a non-craftsman.
