Definitions

  • the present invention relates to an actuating device for roller blinds, in particular for the devices that enable the actuation of the curtains or the fixing at any point during the rolling up or rolling off.
  • the present invention has set itself the task of realizing an actuating device for roller blinds, which not only enables the curtain to be supplied by a coupling group block angular position, but also an immediate disengagement of the coupling group allowed as soon as the curtain is rolled up or down.
  • an actuating and locking device for roller blinds which has a fixed hub with a friction surface and a movable hub with a surface interacting with the first surface, which is subject to the action of an elastic means that the surfaces approaches each other; furthermore, a plurality of balls are accommodated in cam surfaces, while an actuating element for the curtain has means which move the balls in the cam surfaces under the action of the elastic means, and a sliding surface and a driver are provided between the actuating element and the movable hub. This driver is moved after the balls have been moved on the corresponding cam surface, so that the balls remove the interacting surfaces between the fixed hub and the movable hub and thereby release or block the rotation of the movable hub and thus the curtain rolling up.
  • a first realization provides that the cam surface, which forms the sliding track for each ball, is arranged radially.
  • the driver consists of the balls themselves, which wedge between the fixed hub and part of the inner surface.
  • a second implementation provides that the cam surface is arranged peripherally.
  • the driver consists of a partially slidable pin which firmly connects the actuator to the movable hub as soon as the balls have removed the two interacting friction surfaces.
  • cam surface is arranged in some other way, for example along a spiral.
  • the braking surfaces can be formed by interacting conical as well as flat or interacting surfaces which are provided with teeth and corresponding catches which are or are not removed during the release or blocking.
  • 1 denotes the fixed hub and 2 the movable hub, which together form the coupling group.
  • the actuator is designated, which here consists of an actuating disc; 4 are the release and locking balls and 5 denotes the compression spring, which is loaded so that it presses the fixed hub 1 and the movable hub 2 together.
  • the end of the spring 5 is fastened with a washer 6 which is fastened to the shaft by a split pin 9.
  • the fixed hub 1 is blocked on the shaft 7 and has two conical surfaces, namely a first surface la on which the balls 4 slide and a second conical surface lb on which the cooperating conical surface 2b of the movable hub 2 is supported .
  • the two surfaces 1b and 2b are pressed against one another by the action of the spring 5.
  • An open ring 8 is fastened over the hub 2, which is pressed onto the hub 2 and then fastened with a screw.
  • the hub 2 has grooves 2a into which the balls 4 can slide. In this implementation, the number of grooves 2a corresponds to the number of balls 4.
  • FIGS. 2 and 3 show the coupled device (blocked curtain) and the disconnected device Show (curtain in the operating state).
  • the spring 5 presses against the movable hub 2, so that the balls 4 slide along the conical surface la and are arranged in the recess 3a of the disk 3.
  • the surface 1b of the fixed hub comes into contact with the corresponding cooperating surface 2b of the movable hub 2 on which the curtain is mounted; the force they exert holds the curtain in a certain position.
  • the balls 4 slide along the surface 1a due to their rotation through the cam 3a and move radially inwards, the spring being retracted.
  • the balls are arranged in the manner shown in FIG. 3.
  • the movable hub 2 is moved back by a few millimeters with respect to the fixed hub and the spring 5 is thereby further compressed, so that the two cooperating conical surfaces 1b and 2b of the fixed or movable hub are no longer in contact with one another, but are mutually free can move.
  • the disc can be actuated, which now rolls up the curtain without having to overcome the friction due to the clutch.
  • the actuating disc 3 now moves with the movable hub 2, on which the curtain is rolled up, since the balls 4 are clamped between the cam surfaces 3a and the guide grooves 2a. This position of the balls is maintained until a certain moment acts on the disc 3, which causes the curtain to roll.
  • the spring 5 presses the movable hub 2 into its starting position, the balls 4 running inwards along the conical surface la.
  • the part designated by 11 is the fixed hub mounted on the support shaft 10.
  • This hub always remains immobile and firmly connected to the shaft 10 and is used to stop the curtain in any desired location.
  • the hub 11 is provided with a conical part 11b which serves as a friction surface and which couples with the movable hub 12, which also has an inner conical surface 12b which interacts with the surface 11b of the fixed hub 11.
  • the two surfaces 11b and 12b are in contact with one another when the movable hub 12 is pressed against the fixed hub 11 by the spring 5, which is attached at one end to the ring 6 fixed to the shaft 10, while the other end presses against the hub 12, which both rotates on the shaft 10 and slides on it in the longitudinal direction.
  • the curtain is mounted on shaft 12.
  • the front surface of the hub 12, which is opposite to the side on which the spring 5 acts, has a cam-like course; it has some depressions 15, which are separated by flat points 14 and connected to one another by inclined planes 17.
  • a pin 16 is provided which is fixed to the movable hub 12 and which can be taken away the movable hub 12 is used after the actuator has run empty in a certain arc to move the balls 4 on the corresponding cam surfaces, as will be described.
  • An actuating member 13 is arranged between the fixed hub 11 and the movable hub 12, which has the exterior, for example, the course of a disc 13c with a groove into which the cord for operating the curtain is inserted.
  • the curtain cord comes out of the group via the window 11d provided in the fixed hub 11.
  • the actuating member 13 is designed as a ball guide and has (FIG. 5) a hole 13d coaxial with the shaft and can slidably receive the cylindrical surface 18 of the movable hub 12. It also has three cavities 13a for receiving the balls 4 and a curved slot 13b, into which the pin 16 can penetrate and partially slide.
  • the parts are in the arrangement shown in Fig. 6, i.e. the interacting conical surfaces llb and 12b are in contact with each other so that they block the curtain.
  • the balls 4 are located in the recesses 15 and therefore do not touch the surface 11c which forms the bottom wall of the fixed hub, and the spring 5 is extended as far as possible in order to allow the movable hub 12 to adhere to the fixed hub 11, so that the two parts are close together and the curtain is blocked.
  • curtain actuation has started should be, is determined by the n on the disk 13c of the actuator 13 "cord not shown ontlixator this organ by a certain arc rotated while being moved in the holes 13a contained balls. 4 Before the balls 4 arranged in the recesses 15, move along the inclined surface 17 (Fig. 4) until they have reached the flat surface 14.
  • the spring 5 displaces the hub 12 against the fixed hub 11, as a result of which the balls 4 run along the inclined surface 17 so that they are brought back into the depressions 15. In this position, the balls 4 are completely in the hub 12 and no longer remove the hub 11 from the hub 12, so that the curtain is blocked.
