Abstract: In venetian blinds, a combination of a louver clip and a louver sleeve for supporting a louver. The louver sleeve has a cylindrical opening with an obstrusion on the lower part of its periphery having a cross-section in the form of a segment. The louver clip comprises a shank and a stem on top of the shank. The stem is adapted to be introduced in the sleeve. The stem has a longitudinal axial flat adapted to match the flat side of the obstrusion. The stem is provided with an aperture in its upper portion extending through the axial flat. An anchor tab extends from the top of the stem and projects downwardly in the aperture and angularly so as to project outside the contour of the stem. When the stem is introduced in the sleeve, the tab catches the top surface of the obstrusion, which acts as a support for the stem. The advantage of this combination resides in the fact that if the shank breaks away from the stem, another clip is used to push the broken stem out of the sleeve.

Abstract: A vertical louver assembly of the type designed to movably support a plurality of vertically oriented louvers from a horizontally oriented housing and accompanying track structure and a tilt rod extending along the length of the housing. Each louver is supported by a carrier assembly itself including a carrier frame structured to accomplish collective positioning of the louvers along the length of the housing and also in a rotatable orientation about their own longitudinal axis through operation of the tilt rod as well as other control facilities. Each carrier frame includes a biasing assembly disposed and structured to force gear elements into mating engagement with one another and a clutch assembly disposed and structured to allow for realignment of any louver which has become inadvertently disconnected without damage thereto.

Abstract: A venetian blind of the vertical louver type includes an elongated guide track and a plurality of louver carriers supported by the guide track for traverse between open blind and closed blind conditions, each of the louver carriers supporting a louver in generally vertical orientation for traverse with the carrier and for rotation about its longitudinal axis between open and closed louver positions. A louver control mechanism is supported on one end of the guide track and is operative to rotate the louvers to open louver positions prior to traverse along the guide track from a closed blind condition to an open blind condition. In the disclosed embodiment, a rotation rod extends longitudinally of the guide track in cooperative relation with the louver carriers and supports a spool which is actuated by a beaded chain to rotate the rotation rod and effect rotation of the louvers.

Abstract: Herein disclosed is an actuator for actuating an vertical blind or curtain of electric type to be mounted on a mounting support face. The actuator is enabled to eliminate the deformations such as torsions of rotating rods thereto to ensure their rotations by driving the two ends of each of the rotating rods with the torques of a pair of motors. The tension to be applied to a traverse rod can be easily adjusted to an appropriate value by fastening a nut on a tensing threaded rod connected to the traverse rod to tense the traverse rod. Rotation transmitting unit can be held in position in a pivotal state even if the tension is applied to the traverse rod. Since the traverse rod is fitted in a bearing by the face contact between ridges and corners, moreover, the rotating torque is dispersed to enhance the breaking stress at the fitted connection.
