Definitions

  • the subject-matter of the invention comprises a coupling assembly for coupling the shaft of a moving blind to its housing.
  • a building opening shading device comprising a winding shaft with a curtain, suspended on two lateral end faces of a box housing using at least one support piece was disclosed in the description of patent EP2918768B1 .
  • the aforementioned support piece is designed for longitudinal movement with respect to the winding shaft, so that it can assume an assembly position or an working position. In the assembly position of the shaft, the support piece at least partially enters it.
  • the device also comprises a securing device for the purpose of securing the shaft against undesirable movement when it is in the working position wherein the support piece is supported on the surface of an end side of the box.
  • the securing device comprises a stop face part of the box housing end face. The stop face is pointing to the outside of the shaft and comprises a counter stop pin protruding towards the shaft.
  • the counter stop pin is in a securing position, where it is located at the height of the stop surface of one support piece sleeve, which prevents or at least limits the support piece from accidentally pushing into the shaft.
  • the stop face together with the counter stop pin is moved so that it is outside of the support piece sleeve stop, which may be telescopically moved to the assembly position where it is inside the shaft.
  • a solution comprising an assembly coupling the moving blind shaft on the moving blind housing, entailing locking the winding shaft movable sleeve with respect to an intermediate sleeve has also been disclosed.
  • the movable sleeve comprises ridges on its circumference and a movable ring which travels along the longitudinal axis of that sleeve, and once aligned with the ridges they press flush against its outer surface allowing the movable sleeve to be pushed into the intermediate sleeve. This operation is carried out during assembly of such a winding shaft inside the shutter box, when the winding shaft has to be shortened in order to seat it on fixed plugs of pre-determined spacing.
  • Document FR 2 934 307 A1 discloses an assembly for coupling the shaft of a moving blind to its housing according to the preamble of claim 1.
  • variable length of the shaft is particularly important for a flush-mounted shutter during its assembly, and particularly during maintenance works, where the assembly cavity for the box and the shaft is of a certain size limiting assembly space.
  • the variable length of the shaft is achieved through the use of the coupling assembly according to claim 1.
  • the essence of the invention comprises an assembly for coupling the shaft of a moving blind to its housing, made out of a movable sleeve and an intermediate sleeve which move relative to each other so that the movable sleeve is at least partially inside the intermediate sleeve and the coupling assembly is in its working position when axial movement of the movable sleeve inside the intermediate sleeve is locked and in an assembly position, when axial movement of the movable sleeve inside the intermediate sleeve is unlocked, wherein a ring is seated on the movable sleeve with at least one arm locking axial movement of the movable sleeve inside the intermediate sleeve in the working position of the coupling assembly where the ring arm is resting on the stop face of the intermediate sleeve and the intermediate sleeve has at least one longitudinal notch for the ring arm, when the coupling assembly is in the assembly position, wherein transition of the assembly from one position
  • the ring arm has one free end and one end permanently attached to the ring, so that the ring turning around the movable sleeve causes the free end of the arm to move around the movable sleeve from the working position to the assembly position.
  • stop faces of the intermediate sleeve for the arm in the coupling assembly working position are on its outside and number no less than the number of ring arms, and the longitudinal notch for the ring arm in the assembly position of the coupling assembly is located between the stop faces.
  • the free end of the ring arm has a foot.
  • the foot of the free end of at least one arm has a rib designed to align in a groove.
  • a flange locking the longitudinal movement of the ring with respect to the movable sleeve.
  • an elastic element in the form of a spring.
  • Box 5 of flush-mounted shutter is seated in a rectangular building opening with shutter guide rails on its side walls.
  • Rotary shaft 6 is mounted in box 5 housing onto which the shutter blind material is wound.
  • Shaft 6 has two holes, where one constitutes an outlet for shutter drive 7 and the other an inlet for the coupling assembly.
  • the coupling assembly facilitates assembly of shutter shaft 6 in box 5 housing.
  • the coupling assembly can assume two opposite positions: working and assembly. In the assembly position, axial movement of the movable sleeve 1 inside the intermediate sleeve 2 is unlocked, so that movable sleeve 1 partially enters intermediate sleeve 2 when a user wants to insert or remove shaft 6 into the box housing.
  • Spring 4 is located between the sleeves, and, once the force causing movable sleeve 1 to enter intermediate sleeve 2 is removed, it forces movable sleeve 1 to return to its starting position. Whereas the working position of the coupling assembly is achieved when axial movement of movable sleeve 1 in intermediate sleeve 2 is locked. Locking sleeve axial movement is achieved via ring 3 seated on movable sleeve 1 which has flange 13 preventing ring 3 moving along movable sleeve 1.
  • Ring 3 has at least one arm 31 locking the axial movement of movable sleeve 1 in intermediate sleeve 2, and the said arm 31 with its foot 311 in the working position is resting on stop face 21 of intermediate sleeve 2 and intermediate sleeve 2 has at least longitudinal notch 22 for ring 3 arm 31, when the coupling assembly is in the assembly position.
  • the said stop faces 21 of the intermediate sleeve are on its outside and number no less than the number of ring 3 arms, and longitudinal notch 22 for ring 3 arm 31 is located between stop faces 21.
