Abstract
A handle is releasably secured to a rail wall by means of fasteners extending from inside the rail. An actuator shaft pushes against a contact plate to move a movable braking member to stop the rotation of a rod inside the rail.
Claims13
A brake arrangement for a covering for an architectural opening, comprising:
- a rail;
- a rod mounted on said rail for rotation in first and second directions about an axis of rotation relative to said rail, for extending and retracting a covering, said rod having an axial length;
- a brake for stopping the rotation of said rod in at least one of said first and second directions;
- wherein said brake includes a biased movable braking member which is biased in a braking direction transverse to the axis of rotation of the rod and which includes a contact plate;
- and
- a pusher, wherein said pusher defines a contact surface which pushes against the contact plate to push said biased movable braking member opposite to said braking direction to disengage said brake.
3 more elements
A handle arrangement for a covering for an architectural opening, comprising:
- a rail having a U-shaped cross-section and defining a connecting wall, a front wall merging with said connecting wall and having a free front edge, and a rear wall merging with said connecting wall and having a free rear edge;
- a handle mounted on said rail, said handle having a front surface and a rear surface, said rear surface of said handle abutting the front wall of said rail;
- said handle defining a first recess having a rear opening, said first recess being defined by a first guide surface and a first slotted yielding surface, said first guide surface defining a first screw axis which clears the free rear edge of said rail when said handle is mounted on said rail in a first orientation, and said first slotted yielding surface being farther from the first screw axis at the rear opening and tapering toward the screw axis as the slotted yielding surface extends toward the front of the handle.
