US Patent:

20090120593, May 14, 2009

Filed:

Jan 16, 2009

Appl. No.:

12/355599

Inventors:

Leo J. Lesperance - Boulder CO, US

Assignee:

Hunter Douglas Inc. - Upper Saddler River NJ

International Classification:

E06B 9/24

US Classification:

160 8402

Abstract:

A control unit for controlling a lift system in a covering for an architectural opening includes a drive assembly and a brake assembly. The drive assembly includes a spool about which a pull cord can be wrapped or unwrapped and a spring for biasing the spool in a direction to wrap the pull cord thereabout. A drive gear is operatively associated with the spool so that upon a pulling of the pull cord and unwrapping of the cord from the spool, the drive gear is shifted axially into engagement with a driven gear in the brake assembly. The driven gear under such circumstances rotates a driven shaft, which in turn rotates a lift shaft in the covering to raise the covering from an extended position to a retracted position.

International Classification:

A01K 27/00
F21V 8/00

Abstract:

An animal restraint is either a leash or a collar. The animal restraint includes a lighting module and a circuit board, the circuit board enclosed in the lighting module. The animal restraint further includes a first light source connected to the circuit board, such that the first light source does not have a fixed position in relation to the circuit board, the first light source enclosed in the lighting module. The animal restraint further includes a fiber optic connected to and receiving light from the first light source, the fiber optic at least partially in the lighting module. The animal restraint further includes a first flat strap, the fiber optic surrounded by the first flat strap.

International Classification:

B25B 11/02
F16M 13/02

Abstract:

A bracket installation tool includes a tool body having a length extending along a longitudinal axis of the body, a proximal end, and a distal end. The body defines a longitudinal slot extending along the length. The body includes a body mating feature disposed along the longitudinal slot. A handle is coupled with the proximal end and a receiver hitch is coupled with the distal end. The receiver hitch is configured to receive a portion of a bracket for a window covering. A stop is slidably engaged with the slot along the length. The stop includes a lock mechanism. When in a locked configuration, a lock mating feature of the lock mechanism engages the body mating feature to fix a location of the stop. When in a free configuration, the mating features are disengaged such that the lock mechanism and the stop are slidable within the slot.
