Definitions

  • the invention relates to a cord brake for a curtain, in particular Roman blind, with a housing in which at least one Brake roller is slidably mounted and by at least a pulling element is pulled through to actuate a curtain, the brake roller in a first position the traction member clamps and in a second position releases this, the Brake roller is connected to a reversing device, the one in a wall of the housing arranged guide curve and a cooperating with this guide part, which in a carrier is slidably mounted.
  • the invention relates also a Roman blind with such a cord brake.
  • a brake roller is also provided with a grooved Wall works together. By tilting the cord or of the cord bundle, this brake roller can move upwards into a braking position be moved. Will be on the line or on the line bundle pulled, the brake roller slides down and thereby the braking effect is canceled.
  • the cord brakes mentioned are so-called "single stage brakes". Two-stage are also known Brakes with which the curtain is lowered or raised Position can be held.
  • the brake roller has here two positions, which are adjustable by means of a reversing device are.
  • the disadvantage of these cord brakes is that they have a lot of individual parts. So they are in the making, assembly and revision work and expensive.
  • the invention has for its object a cord brake to create the kind that is easier with fewer parts can be manufactured and assembled.
  • the task is in a cord brake of the generic type solved that the guide curve of the reversing device arranged so is that the carrier is subjected to a radial force of the pulling member on the brake roller essentially said wall not burdened and thus between the carrier and the named Wall essentially no friction is present.
  • the Exertion of force to bring the brake roller into the braking position is very low.
  • Elaborate means to move the tension member between to clamp two rollers and on the necessary spring elements can be dispensed with. It has been shown that the cord brake according to the invention due to the low mentioned Friction only requires a brake roller. The train organ does not have to be tilted to operate the curtain, actuation is therefore possible with a vertical line course.
  • the cord brake according to the invention can be significantly fewer individual parts and thus much easier and manufactured more cheaply.
  • a major advantage of the inventive Cord brake is that the traction element mounted much easier than before or by the cord brake can be pulled through. This has significant advantages both when assembling the system and when washing of the curtain.
  • the figures show a venetian blind 1 with a curtain 4, the with a Velcro 3, a hook band 3a and has a pile ribbon 3b, detachably with a profile rail 2 connected is.
  • the profile rail 2 is in turn with rings 29 or another suitable connecting device with a Decoration rail 28 connected, which is attached to a building wall is, as shown in Figure 3.
  • the hook tape 3a is fixed to the profile rail 2 and the pile tape 3b firmly attached to the back of the curtain 4.
  • the curtain 4 can be pulled off the rail 2 as shown in FIG and be attached to it again in a known manner.
  • the cords 5a of a pulling element 5 lead to the Shirring 4 and are known in the back of the hanging 4 wise eyelets 6 attached.
  • the tension member 5 is thus a bundle of several Laces 5a, each at the bottom not shown here of the curtain 4 are attached.
  • the tension member 5 is by a Cord brake 7 passed through, which is releasable at one end of the Profile rail 2 is attached. If the traction element 5 according to FIG 3 moved in the direction of arrow 30 by hand, see above the curtain 4 is gathered according to arrow 31, i.e.
  • the cord brake 7 has a housing 10 on which a holding element 8 is formed, which is designed as a locking member and which is snapped into the profile rail 2 according to FIG. 1. to Fixation, a screw 32 is provided, which is still in Figure 1 screwed in further and placed on the profile rail 2. In order to the housing 10 is stable and yet simple detachably fixed to the profile rail 2.
  • two deflection rollers 9 are each on a horizontal, molded axis 9a mounted. These two roles 9 serve to redirect the tension member 5, optionally to the right according to Figure 2 or to the left, depending on which end of the Rail 2 the cord brake 7 is attached. It usually does only one of the two pulleys 9 used. in principle but can also both roles 9 for each part of the Cords 5a are used.
  • Over the pulleys 9 is one Wall 33 arranged on the side one down projecting retaining finger 17 is formed. Grasp these holding fingers 17 each a pulley 9 and prevent the tension member 5 unintentionally slipped from the corresponding deflection roller 9. Between the holding fingers 17 and the corresponding deflection roller 9 there is a space so that the traction element 5 can be removed from the cord brake 7.
  • the housing 10 has an opening 19 at the lower end which the tension member 5 is pulled freely. Below this The traction element 5 protrudes from opening 19 according to FIGS. 1a and 1b below and can be pulled here by hand. Above opening 19 is located behind the cover 11, a brake roller 18 on an axis 15 is freely rotatable and on its circumference has a plurality of axially extending ribs 20. The brake roller 18 is mounted on two support arms 23a of a carrier 23. In the housing 10 are laterally slits 14, through which one end of the axis 15 is visible. These slots 14 allow the axis 15 with a wire or a similar instrument in the longitudinal direction and thus to release the brake roller 18 from the support arms 23a.
  • the cover 11 After acceptance the cover 11 can then remove the brake roller 18 and be replaced by another.
  • the slots 14 are not mandatory and can be replaced by other guide elements.
  • the cover 11 has pegs 12 formed on the side and 13 which fit into corresponding recesses in the housing 10 are inserted or engaged. So it is possible without tools remove the cover 11 and put it back on.
  • FIGs 6a to 6c are individual steps when snapping on the lid 11 shown.
  • the carrier 23 has a bearing plate 23b, which is on the back 27 of a wall 21 is arranged.
  • This bearing plate 23b has on the inside a recess 34 in which a guide part 24a is guided laterally.
  • This guide part 24 has a guide pin 34 with a guide curve 25 works together.
  • This guide curve 25 is represented by a Recess formed in the back of the wall 21.
  • This Guide curve 25 is heart-shaped according to FIGS. 4 and 5 and known per se.
  • the guide curve 25 has an upper and a lower position.
  • the carrier 23 In the lower position according to FIG. 4, the carrier 23 is in the position shown in Figure 1.
  • the brake roller 18 is located in a lower region of a toothing 22, with which the brake roller 18 clamps. Is the brake roller 18 in this lower position, the traction element 5 in the direction of Arrow 30 pulled down according to Figure 3 and thus the curtain 4 are gathered.
  • the tension member 5 slides on the Circumference of the brake roller 18 without being rotated. Now the train on the tension member 5 so reduced that the weight of the Blinds 4 moves the pulling element 5 upwards in the opposite direction, so the brake roller 18 is due to the friction of the tension member 5 the brake roller 18 rotated and this together with the carrier 23rd moved up into the position shown in Figures 1b and 5.
  • the brake roller 18 meshes with the toothing 22 here Guide part 24 slides accordingly in the guide curve 25, the guide part 24 is correspondingly deflected laterally.
  • the tension member 5 is now between the brake roller 18 and an inclined inside 16 of the Cover 11 clamped, as shown in Figure 1b. Will the tension member 5 released, it remains due to the clamping between the Brake roller and the inner roller 16 fixed. The curtain 4 remains thus in the gathered position. It is now essential that in the clamped Condition as well as with the mentioned movement of the brake roller 18 upwards exerted by the tension member 5 on the brake roller Force the friction between the carrier 23 and the wall 21 not increased. By the said force, which is essentially horizontal acts, the carrier 23 of the wall 21 is slight lifted.
  • the friction between the carrier 23 and the wall 21 is very small. This also applies to the friction of the Guide part 24 in the guide curve 25. This has the effect that the brake roller 18 with a very small force upwards and can be moved down.
  • One to the usual second Roller with which the tension member 5 is pressed against the brake roller 18 is not necessary here.
