Definitions

  • the invention relates to a reel in particular intended to receive an operating strap for a roller shutter.
  • a roller shutter is constituted by an apron which comes to wrap around a drum, driven in rotation by means of a crank or a strap.
  • a roller shutter operated by a strap the latter is moved back and forth between two extreme positions which correspond one to the high position, the other to the low position of the apron.
  • the free end of the strap is preferably fixed on a reel, which has tensioning means, allowing the strap to be wound on itself.
  • tensioning means are usually constituted by a spring.
  • This reel delivered with the spring tensioned and protected by a protective case.
  • This reel has a tongue secured to the drum energized, and. Maintained outside the housing by means of a retaining rivet. After fixing the strap on the tongue, you can remove the retaining rivet, which causes the spring to relax and the strap to wind up on itself. But then, it is necessary to proceed to the installation and the fixing of the strap clamp in the opening of the case by using for example a hammer or pliers. This operation can be dangerous for the hands of the installer.
  • this type of reel has the disadvantage of not being easily removable and requires replacement in the event of accidental breakage of the strap.
  • the main object of the present invention is to provide a reel delivered with a protective box which allows the tensioning of the elastic means which can drive the drum, from the outside of the box, the strap being already mounted on the reel, and the housing being closed.
  • Another object of the present invention is to provide a reel such that the tensioning of the elastic means which can drive the drum, does not present a danger to the hands of the installer.
  • Another object of the present invention is to provide a reusable reel in the event of accidental rupture of the strap.
  • Another object of the present invention is to provide a reel whose installation is simple, the number of parts reduced, and which allows the intervention of a non-experienced installer in the event of an incident.
  • Another object of the present invention is to provide a reel, the fixing of the strap on the drum is carried out by means which pinch the end of the strap.
  • the retractor in particular intended to receive an operating strap for a roller shutter, comprising in particular a housing constituting a closed casing, an opening for the exit of the strap, a drum for winding the strap on itself , elastic means capable of being tensioned to drive the drum and allow the belt to move back and forth from the inside of the housing, is characterized in that it has means accessible from outside the casing closed to carry out said tensioning.
  • FIGS 1 and 2 show a preferred embodiment of a reel according to the invention.
  • This reel in particular intended to receive a maneuvering strap for a roller shutter, comprises a case 1 constituting a closed casing, which has an opening 2 for the exit of the strap 3 and a winding drum 4 of the strap on it -even.
  • This reel also includes elastic means capable of being tensioned to drive the drum 4 and allow the back and forth of the strap 3 to go inside the housing 1.
  • the drum 4 being placed inside the housing 1, the reel according to the invention has means accessible from the outside of the closed housing 1 for carrying out the tensioning of the elastic means driving the drum 4.
  • the placing under tension of the elastic means is carried out while the strap 3 is already mounted on the drum 4 and the housing 1 is closed.
  • the drum 4 in the housing 1 has an opening 5 masked by a removable cover 6 and, the means accessible from outside the housing 1 for tensioning the elastic means will advantageously consist of cover 6.
  • the winding drum 4 has an axis of rotation 7, and the elastic means capable of being tensioned are driven by this axis 7 of the winding drum 4.
  • the cover 6 is integral with this axis 7. Consequently, the rotation of the cover 6 is accompanied by the rotation of the axis 7 of the drum which causes the elastic means to be tensioned.
  • the drum 4 is constituted by two parallel flanges 8 and 9, perpendicular to the axis of rotation 7, and connected by the cylindrical winding surface 10 of the strap, whose generatrices are parallel to the axis of rotation 7.
  • the housing 1 its shape is defined from the size of the drum 4.
  • This housing is essentially constituted by two walls 11 and 12 perpendicular to the axis of rotation 7 of the drum and, connected by a side wall 13 including generators are preferably parallel to the axis 7.
  • the cover 6 is preferably located on one of the walls perpendicular to the axis 7, for example on the wall 11. It will advantageously consist of a panel.
  • the opening 2 for the exit of the strap 3 is made in the lateral surface 13 of the boot 1.
  • the elastic means capable of being 'tensioned, they are advantageously constituted by a spiral spring 14, one of the ends 15 of which is integral with the drum 4, and the other end of which 16 can be driven by the axis of rotation 7 of the drum. Consequently, if the drum 4 is kept in a determined position, the rotation of the cover 6 generates a tension in the spring 14 which tends to oppose the direction of rotation of the cover 6.
  • the spring 14 will preferably be placed in the drum 4 around the axis of rotation 7.
  • the cover 6 has on its outer face 17 one or more notches or asperities which make it possible to drive it in rotation about the axis 7.
  • a notch 18 illustrated in the center of the cover 6 is illustrated.
  • the opening 5 is preferably circular and of sufficient size to allow the engagement of the drum 4 in the housing 1, the cover 6 has a circular shape whose diameter is greater than the outside diameter of the drum 4.
  • the cover 6 For the tensioning of a reel according to the invention, one starts by fixing the strap 3 on the drum 4, then, one places the cover 6 on the opening 5. To proceed with the setting operation tension of the spring 14, the operator causes the cover 6 to perform the desired number of turns while keeping the drum 4 fixed by means of the strap 3. When the operation is complete, the cover 6 must be immobilized in rotation relative to the housing 1. To this end, the cover 6 has means which make it possible to immobilize it relative to the housing 1; for example, the internal face 19 of the cover has at least one lug 20 which engages in a notch 21 formed in the housing 1.
  • the cover 6 has on its inner face 19 two lugs 20, diametrically opposite, and located at its periphery.
  • the housing 1 has at the periphery of the circular opening 5 a shoulder also of circular shape 22 on which the cover 6 is applied when the latter is placed on the housing.
  • the housing 1 has on the edge of the opening 5, at the shoulder 22, two notches 21, diametrically opposite, in which come to rest the pins 20 of the cover. By the presence of these two notches 21, the cover 6 can be immobilized on the housing in two opposite positions.
  • the axial immobilization of the cover 6 and the drum 4 on the housing 1 will advantageously be carried out at the level of the axis 7 as illustrated in FIG. 3.
  • the length of the axis 7 of the drum is such that its end 23, opposite the cover 6, is located substantially in the plane of the wall 12 and opens out of the housing through a hole 24 made in the wall 12.
  • the end 23 of the axis has a threaded hole 25 in which a screw 26 is engaged which axially immobilizes the cover 6 on the housing 1.
  • Figure 1 illustrates in section 40-40 the connection of the end 16 of the spring with the axis 7 of the drum.
  • the axis of rotation 7 is constituted by an axis of square section 27, on which is placed a ring 28, of circular outer section, but which has in its central zone a tooth 29 which can engage in the opening 30 made in the end 16 of the spring 14.
  • the tooth 29 is such that only rotation in one direction of the axis drives the end 16 of the spring.
  • the direction of rotation which causes the spring to be tensioned is illustrated in FIG. 1 by the arrow 31 directed in the opposite direction to the hands of a clock.
  • the attachment of the end 15 of the spring to the drum is of a known type.
  • a tongue 32 located from the winding surface 10, inside the drum 4, engages in an opening 33 made in the end 15 of the spring. This tongue 32 will be properly oriented to obtain tension on the spring 14 when the cover 6 is moved in the direction of the arrow 31.
  • the winding surface 10 of the drum has a depression area 34 in which is placed a tilting plate 35 which clamps the end of the strap 3.
  • the plate 35 disposed parallel to the axis 7 has two lugs 36 which are introduced into two holes 37 made in the flanges 8 and 9 of the drum.
  • the end of the strap 3 is introduced into the vacuum zone 34 under the tilting plate 35 and then it is folded around the tilting plate 35 on the side of its end.
  • the plate 35 thus acts as a self-clamping clamp which holds the end of the strap on the winding surface 10.
  • the housing of the retractor according to the invention will advantageously have in the opening 2 a strap clamp 38 known to those skilled in the art which serves to immobilize the strap 3 relative to the shoemaker.
  • the housing 1 has at its upper part and at its lower part two fixing lugs 39 which are used to fix the reel on its support.
  • the procedure is as follows: the housing 1 is fixed to the support using the lugs 39, the flap is placed in the low position, the drum 4 is removed of the housing, we introduce the strap 3 into the opening 2 and then we fix the end of the strap 3 on the drum 4 by means of the clamp 35. Then, we put the cover 6 on the housing, we come axially immobilize the cover 6 using the screw 26, leaving sufficient axial clearance to allow the cover 6 to rotate, then the cover 6 is rotated by means of the notch 18 while keeping the strap 3 fixed. The maximum spring tension is obtained for about ten turns, but this tension can be adjusted to a different value depending on the dimensions of the roller shutter. Then, the cover 6 is immobilized in rotation by introducing the lugs 20 into the notches 21, and the screw 26 is tightened on the axis 7 to immobilize the cover and the drum in the housing.
