Definitions

  • the invention relates to a Roman blind with a winding shaft with fastenings for the ends of drawstrings.
  • DE-A-39 31 090 describes a winding device for the pull cords of venetian blinds.
  • the upper ends of the draw cords of the venetian blind are removably attached to a fixed, rotatable shaft on which they can be wound up or unwound, thereby the curtain is raised or lowered.
  • the risk of entanglement and entanglement of the individual pull cords with each other when removing and / or reapplying the curtain is to be avoided in that the upper end of each pull cord is guided by a guide element fixed above this shaft before it is attached to the shaft.
  • DE-A-38 11 326 shows a reversible winding system for interchangeable bobbins, in which the pull cords of a removable Roman blind, on the ends of which Velcro strips are attached, are wound on bobbins which are covered with a corresponding (eg, fleece part / Velcro part) Velcro strip .
  • the reel spools are mounted on a shaft that is mounted in bearings that are firmly connected to the building.
  • the Roman blind is assembled and disassembled by placing or removing the Velcro strips on or off the Velcro coverings of the spools.
  • Strips of a flexible material placed on the shaft can also be used as coils, the total width of which is less than half the shaft circumference and two each parallel, right-angled, flat projections projecting from the shaft axis. Even with this winding system, tangling and devouring of the pull cords cannot be avoided.
  • CH-A-672 658 relates to a venetian blind with an elevator drum for receiving a windable or unwindable strand, the elevator drum being provided with an external thread and being rotatably mounted in a fixed threaded nut in order not only to lift the venetian blind but also to lift it to be able to operate when lowering.
  • Attachment of the pull cords to a winding shaft for shirring curtains by means of plug-like shaped bodies which are inserted in bores of the winding shaft is not provided. Rather, the strand or the pull cord is fastened to the elevator drum by means of screws.
  • DE-A-30 09 992 describes a foldable or pull-up curtain that should be removable and attachable easily and quickly.
  • the curtain is provided at appropriate points with a plurality of releasable connecting elements from two parts that can be coupled as desired, one part being attached to the curtain and the other part carrying an uninterrupted or interrupted small ring which acts as a holding and guiding member for a cord serves, which forms part of the pulling and lowering device of the curtain.
  • a plurality of tapes extending in the vertical direction are provided, which are attached to the curtain at appropriate intervals.
  • a first part of a plurality of tongue and groove connections designed here as snap fasteners is attached to these bands at regular intervals.
  • the other corresponding Part of the push buttons serving as a tongue and groove connection is designed in such a way that it has a closed ring or an open ring or in any case an openable ring for carrying out the individual pull cords.
  • the fastening device should be inexpensive to produce, the attachment and detachment to and from the winding shaft being carried out with ease. Unintentional detachment of the pull cord ends from the winding shaft, as well as entanglement and entanglement of the individual pull cords with one another, is completely excluded.
  • 100 denotes a hollow winding shaft, in which holes 12 are provided at the points at which a pull cord 150 is to be detachably fastened, which are suitable for receiving the tightly fitting and therefore fixed fastening insert 13 .
  • This fastening insert 13 consists essentially of a preferably cylindrical main body 13a which is expediently open at the bottom and which is closed at the top by a roof-shaped cover 13b provided with a central opening 13c. Through this opening 13c this is covered with a thickening 14, e.g. a knot or a melt drop, provided end of the pull cord 150 pulled through from below.
  • At least the main body 13a of this fastening insert is made of elastic material such as UV-resistant elastic or another suitable plastic. However, the entire fastening insert is preferably made in one piece from the same elastic material.
  • the outer diameter of the main body 13a is so on Matched inner diameter of the bore 12 that it can be inserted into and pulled out again without too much effort, but is not loosened or even thrown out by accidental vibrations, for example.
  • the fastening insert 13 which in addition to a cylindrical shape can also have other geometric shapes with different geometric cross sections, can have the designs shown in FIG. 1.
  • the holes provided in the winding shaft 100 for the fastening inserts 13 have dimensions and shapes which correspond to those of the fastening inserts 13, so that a snug fit and press fit of the fastening insert 13 in the hole is ensured.
  • Fig. 3 shows a portion of an assembled winding shaft 100 with guide rings 16 for the pull cords 150, the attachment of these pull cords is accomplished on the left side of the figure in the manner according to the invention, in the right part of the figure for comparison one according to DE-A -38 11 326 detachable fastening of the pull cord ends carrying a Velcro strip on the winding shaft provided with corresponding Velcro coverings is reproduced.
  • the winding shaft 100 is designed as a cylindrical hollow shaft or as a solid shaft. Its circumferential wall surface is labeled 111 (Fig. 5).
  • the winding shaft 100 is provided with a longitudinal groove 120.
  • the longitudinal groove 120 which extends from one end to the other end of the winding shaft 100, has an approximately rectangular cross section.
  • the longitudinal groove 120 is delimited by the side wall surfaces 121, 122 and the bottom wall surface 123 (FIG. 5).
  • a number of receiving openings 130 are provided, which are designed as through-bores 130 '. These receiving openings 130 are formed at equal intervals in the region of the longitudinal groove 120, but a different arrangement of the receiving openings 130 can also be provided. In those cases in which the winding shaft 100 is designed as a hollow shaft, the receiving openings 130 are designed as through bores 130 '. If the winding shaft 100 is designed as a solid shaft, then the receiving openings 130 consist of bores or blind bores.
  • Each plug-shaped shaped body 140 consists of a head-like section 141 and a neck-like retracted section 142.
  • the diameter and shape of the through-holes 130' correspond to the shape and cross-section of the neck-like drawn-in section 142 of the stopper-shaped shaped body 140, so that after inserting the plug-shaped molded body 140 into a bore 130 'of the molded body under a press fit on the the bore 130 'delimiting wall is held.
  • the plug-shaped molded body 140 can be designed as a solid body; however, it is also possible to design the plug-shaped molded body 140 as a hollow body.
  • This plug-shaped molded body 140 is preferably made of resilient plastic, but other suitable material can also be used for the molded body 140.
  • the head-like section 141 of the plug-shaped molded body 140 which protrudes with a circumferential section from the circumferential plane of the neck-retracted section 142, is dimensioned such that, after the neck-like section 142 has been inserted into a bore 130 ', the head-like section 141 on the bottom wall surface 123 of the Longitudinal groove 120 rests in the area of the through hole 130 '.
  • the end 151 of the pull cord 150 is connected to the plug-shaped molded body 140 (FIG. 7).
  • the surface 141a of the head-like section 141 of the plug-shaped molded body 140 is designed to run in an arcuate manner, the surface 141 corresponding to the course of a part of the circle on which the winding shaft 100 is based, ie the radius of the pitch circle which corresponds to the surface 141a of the head-like section 141 of the plug-shaped body 140 is based, corresponds to the radius of the circle or the diameter of the winding shaft 100.
  • the take-up shaft 100 is designed as a hollow shaft, then the longitudinal groove 120 in the wall surface 111 of the take-up shaft 100 is designed as a wall surface recess, in which the receiving openings 130 for the plug-shaped shaped bodies 140 are provided as through holes 130 '.
  • the longitudinal groove 120 with the receiving openings 130 can extend over the entire length of the winding shaft 100. According to a further embodiment, however, there is the possibility of providing the longitudinal groove 120 in the form of individual sections lying one behind the other in the winding shaft 100, so that each longitudinal groove section then has a length which makes it possible to receive two or three or a different number of receiving openings 130.
  • the longitudinal groove 120 can also have a different cross-sectional shape than that shown in the drawings.
  • the cross-sectional shape of the longitudinal groove 120 can be adapted to the cross-sectional shape of the head-like section 141 of the plug-shaped shaped body 140.
  • the neck-like section 142 of the plug-shaped molded body 140 can have a circular, but also a different cross-sectional shape.
  • the receiving openings 130 then have a corresponding shape.
  • the height of the head-like section 141 of the plug-shaped molded body 140 is equal to or less than the height of the longitudinal groove 120, so that the plug-shaped molded bodies 140 do not protrude from the circumferential plane of the winding shaft in the inserted state.
