Abstract
In a vertical blind with a blind head and a number of carriers supported for reciprocating movement in the head, and holders respectively supported in the carriers for pivotal movement and adapted to support a plurality of vertical vanes therefrom, with a control for controlling the reciprocating movement of the carriers and the pivotal movement of the holders including a tilt rod: first bevel gears respectively rotatably supported in the carriers and mounted for rotation with the tilt rod, and second bevel gears respectively connected to the holders and respectively mounted for meshing engagement with the first bevel gears. The carriers are interconnected by special spacer bands and have special openings for receiving the cord for traversing or drawing the blind.
Claims34
A vertical blind, comprising:
- a blind head, a plurality of carriers supported for reciprocating movement in said head, a plurality of holder means respectively supported in said carriers for pivotal movement and respectively adapted to support a plurality of vanes therefrom, and control means for controlling said reciprocating movement of said carriers and for controlling said pivotal movement of said holder means, said control means including rod means rotatably supported in said head, said rod means extending in a substantially vertical plane substantially bisecting said carriers, means for rotating said rod means, a plurality of first bevel gear means respectively rotatably supported in said carriers and mounted for rotation with said rod means in said plane, a plurality of second bevel gear means respectively connected to said holder means and respectively mounted for meshing engagement with said first bevel gear means and having substantially vertical axes of rotation located in said plane, whereby rotation of said rod means by said rotating means will rotate said holder means, each of said carriers comprising seat means for supporting the respective holder means, and also comprising bearing means for rotatably supporting the respective first bevel gear means in a position such that said first bevel gear means holds the respective holding means on said seat means.
In a vertical blind having a blind head:
- at least one carrier supported for reciprocating movement in said head, a holder supported in said carrier for pivotal movement and adapted to support a vane therefrom, a first bevel gear rotatably supported in said carrier in a substantially vertical plane substantially bisecting said carrier, a second bevel gear connected to said holder mounted for meshing engagement with said first bevel gear, and having a substantially vertically extending axis of rotation located in said plane, said carrier comprising a seat for supporting said holder, and a bearing rotatably supporting said first bevel gear in a position such that said first bevel gear holds said holder on said seat.
