Definitions

  • the present invention relates to improvements made to roller shutters. It relates more particularly to the mechanism transmitting the rotational movement from a crank or a motor along a determined axis, in a rotational movement along a generally perpendicular axis, this rotational movement is generally transmitted to a winch secured to the 'winding shaft driving the roller shutter deck in translation.
  • the present invention therefore aims to overcome these drawbacks, by proposing an angle deflection device, mounted on an oscillating frame, which allows the axis of the drum winch to be oriented, crossing the wall, in a position such that it either collinear with the axis of the crank.
  • the angle transmission device object of the invention, is characterized in that it comprises a cradle formed by two parallel flanks and joined by two curvilinear walls, the internal faces of said flanks being further provided with grooves allowing the movement of a box comprising housings through which is positioned a pinion assembly comprising at each of their ends an engagement zone and a rod allowing the fastening with the winch axis of the roller shutter drum and with the operating axis, said cradle cooperating with the wall section by means of a base forming a support.
  • the angle transmission device essentially comprises a cradle 1, formed by two parallel sides 2, 3 joined by two curved walls 4, 5, so as to constitute a box 6.
  • Each of the sides 2, 3 is provided on its inner face 7, 8 with a groove 9 with a flat or spherical imprint; these imprints cooperate with a housing 10.
  • This housing also includes lateral parts 11, 12 of profile similar to the imprints present on the sides 2, 3 of the cradle 1, these lateral parts being joined by means of a crown 13.
  • the housing 10 is produced from a cylindrical portion and in particular comprises, on the periphery of the crown 13, housings 14, 14 ′ projecting perpendicularly and emerging, by one of their ends 15, 16, into the internal cavity 17 of the cylindrical portion of the housing 10. Furthermore, provision is made to arrange these housings 14, 14 ′ at an open angle, between the right angle and the flat angle greater than the right angle, such as in particular 120 ° . Each of the housings 14, 14 ′ further receives a team 20 of pinions 18, 19 whose inclination of the teeth depends on the angular offset between the two respective axes of the housings.
  • a crew 20 essentially comprises, at one of its ends 21, 22, an engagement zone 23 carrying the toothing, while at the other end 24, 25, the crew 20 comprises a rod 26 which s adapts by known means such as in particular by an end cavity, of the hexagon socket type 27, or by means of radial bores 28, in order to ensure its attachment to the axis coming from the crank 29, or to axis 30 of the drum winch carrying the apron.
  • the imprints 9 present in the lateral flanks 2, 3 of the cradle 1 authorize an angular rotation or pivoting according to the type of imprint of the housing 10 provided with its angular gear pair.
  • the openings 31, 32 present on the walls 4, 5 curvilinear and which allow the passage of the housing 14, 14 'are slightly larger in diameter and can if necessary be oblong.
  • the cradle 1 cooperates with the wall panel via a base forming a support 33.
  • This support comprises a flat face 34 intended to be in contact with the wall panel, while the opposite face 35 is of curvilinear profile, similar to that of the cradle.
  • the support 33 is moreover provided with a plurality of holes 36, 37 for the passage, on the one hand of an assembly 20 and on the other hand, for the fixing means such as screws, of the support 33 on the Wall.
  • the fixing means also make it possible to trap, at the countersinks 39, 40, and therefore to secure one of the curvilinear walls 4, 5 constituting the box 6, by virtue of the support of the fixing means on a shoulder 38 produced. on a part set back from one of the curvilinear walls 4, 5.
  • a slide 41 is interposed between the support 33 and the cradle 1, the female part possibly being arranged on the side 35 of the support 33 and the male part on one of the external faces of the cradle 1.
  • the slide 41 optionally has a plurality of guide surfaces, thereby limiting the degrees of freedom of the cradle 1 on the support 33, to a single direction.
  • the fixing means no longer trap the cradle 1 on the support 33, the attachment of the latter being effected by the shape of the slides and in particular by their dovetail profile.
  • the angular clearance between the winch axis of the roller shutter drum and its operating axis, by crank is at least 120 ° around d '' a mounting position of the support relative to the axis of the roller shutter, it being understood that the articulation or slide system allows an angular offset around this position of a few additional degrees, preferably of the order of more or less 5 °, thus making it possible to compensate for any dimensional tolerances of the wall.
