Definitions
- the subject of the invention is a device for winding a blind suspension cord comprising a winding drum, on which the end of at least one suspension cord is fixed, and means for winding the cord in regular turns without overlapping.
- the blinds whether they are fabrics, Venetian blinds, pleated blinds or other, generally have two hanging cords, one end of which is fixed to the winding drum and the other end of which is fixed to the free end. of the awning.
- two hanging cords one end of which is fixed to the winding drum and the other end of which is fixed to the free end. of the awning.
- the axially displaceable winding drum has at one end a threaded part.
- a corresponding threaded part must be provided on its support.
- an arrangement must be provided to allow both the drive in rotation and the translation induced by the threaded parts. All this is a source of complications and additional costs.
- the spaces required for axial movement must be left free and in some embodiments (CH 400 816) they constitute dead spaces which increase the size of the blind support.
- the invention aims to obtain a regular winding of the cord without axial displacement of the winding drum.
- the winding device is characterized in that the winding drum is mounted fixed in translation in a frame having a guide means for the vertical section of the cord and in that the means for ensuring a winding of the cord in regular turns without overlapping consist of a sliding nut immobilized in rotation and in engagement with a thread formed on the winding drum, said sliding nut moving between the end of the cord fixed to the winding drum and said means of cord guide.
- the turns are formed in abutment against a lateral face of the sliding nut. If the screw pitch is equal to or greater than the diameter of the cord, it is then wound in regular turns without overlapping.
- No other nut can be fitted portable players on the same winding tube, as well as establishing a kinematic connection between several winding tubes.
- the cord Over at least most of the length of the winding of the cord on the winding drum, the cord must pass from one side to the other of the sliding nut. For reasons of saving space and in particular if the winding drum with its sliding nuts is mounted in a housing, the cord passes through the sliding nut.
- This passage of the cord in the sliding nut can be advantageously used to control a retractable stop, as is the case in the device shown in document EP 0 380 346.
- the retractable stop can be constituted by a simple rocker resting on the section of the cord passing through the sliding nut so that a tension on the cord has the effect of lifting this rocker and of disengaging the stop from the counter-stop formed on the winding drum.
- Figure 1 is a partial view in axial section along I-I of Figure 2, of a blind winding drum in a position close to the complete winding.
- FIG. 2 is a cross-sectional view along II-II of FIG. 1.
- Figure 3 is a view similar to that of Figure 1, blind completely unrolled.
- FIG. 4 is a cross-sectional view along IV-IV of FIG. 3.
- the winding device shown comprises a box 1 of rectangular parallelepiped shape open towards the top and provided with two end flanges, such as the flange 2, supporting a tubular motor 3 whose casing 4 carries and rotates a winding drum 5 provided with a screw thread engaged with a sliding nut 6 of square shape with sides of length very slightly less than the internal width of the housing 1, so that the sliding nut 6 is immobilized in rotation but that it can move along the winding drum 5 during the rotation thereof.
- the end 7a of a cord 7 is fixed at the end of the winding drum 5 opposite the flange 2 at the end of the winding drum 5 opposite the flange 2 .
- This fixing is ensured by any suitable means, for example a screw, a slot or a ring.
- the cord 7 passes through the bottom wall of the housing 1, near the end flange 2, through an eyelet 8 which serves as a guide means for the cord 7 so that the latter descends vertically.
- the tubular casing 4 carries a second winding drum similar to the drum 5 on which a second cord is wound.
- These two cords are fixed to a load bar 9 which constitutes the lower end of the blind, for example a blind with slats.
- the sliding nut 6 has, in its lower part, a vertical slot, directed along the axis of the winding drum, for the passage of the cord 7.
- the sliding nut 6 has a vertical internal housing 11 in the one of the lower angles which is articulated around a horizontal axis 12, a retractable stop 13 consisting of a V-shaped piece whose lower arm 13a transversely crosses the slot 10 and whose other arm 13b is intended to cooperate with two counter-stops 14 and 15 each formed by a radial wall of a groove extending all along the winding drum 5 and diametrically opposite.
- the bottom of the grooves is convex and practically tangent to the envelope of the winding drum.
- the winding drum 5 can still rotate clockwise, i.e. in the winding direction of the cord, while in the another direction the end of the arm 13b can abut against one of the counter-stops 14 or 15.
- the latter has the advantage of great simplicity and making it possible to reject the point of entry of the cord into the box 1 at the quasi-end of the blind.
- the device according to the invention can of course also be used with manual training.
- the winding drum does not have to be mounted in a box.
- the retractable stop could have another shape and be provided with a spring tending to keep it in the locked position.
- the tubular casing generally carries a second winding tube provided with a screw thread in the opposite direction to that of the illustrated winding tube and carrying a second sliding nut moving in the opposite direction to that of the sliding nut shown .
