The present disclosure relates to a barrier system for shielding humans from harmful exposure to fire, smoke, noxious fumes, or contaminated air. Some embodiments provide a deployable barrier system that has a barrier retract assist system configured to assist a user in manually moving the barrier from the deployed position toward the retracted position with at least a portion of the barrier being rolled onto the barrel portion for egress past the barrier. The retract assist system can be positioned inside of the barrel portion.

A mounting assembly for a roller window shade includes a mounting bracket, a motor coupled with a shade tube of the shade, a battery, a charging port and a power source that can be magnetically attached to the charging port. The mounting bracket includes a body having a first surface and a second surface and a protrusion fixedly coupled with the body and extending perpendicularly from the second surface. The first surface bears against a flat surface. The motor defines a recess that receives the protrusion. The battery is in electrical communications with the motor and the charging port. The mounting bracket and shade tube can obscure the battery from view. The power source can be a power cord that can be magnetically attached to the charging port using a attachment rob having a grasping end.

A blind control for a window covering having a narrow profile; and particularly relates to a control module for a window shade where the location of the drive mechanism is selected to minimize the gap between the end of the window shade and inside edge of a window opening; locating the drive mechanism in a shell disposed in a housing to rigidify a reduced thickness of the drive so as to minimize the gap; and use a single rod depending from the control module to activate the drive mechanism in a safe and secure manner.

The invention also includes a housing with an end wall adjacent one end of the shade; a clutch projecting from said end wall and rotatable about a clutch axis, a drive gear engageable at one end of the clutch for rotatably driving said clutch and shade, said drive gear disposed in said housing adjacent said end wall; and a wand for driving said drive gear.

The invention provides for a wand to raise and lower the window shade.

The disclosure includes various keypad features, buttons, labels, shapes, sizes, format and materials. The system may comprise a processor; a keypad in communication with the processor and configured for controlling a window shade; capacitive or physical buttons on the keypad, wherein one of the capacitive buttons may be configured to set the window shade to a preset position; a proximity sensor; and a communication card. The processor may determine an override pattern to return the window shade to an automatic mode after a period of time from an override request. The capacitive buttons may include haptic feedback or visual feedback. The system may also include a scheduler and/or receive weather conditions. The system may also include an ambient light sensor.

Present disclosure relates to several adjustable roller shades. Adjustable roller shade includes: roller shade fabric winding shaft, weight, movable pulley, two traction ropes, and four winders. A roller shade fabric is wound on roller shade fabric winding shaft forming upper edge of adjustable roller shade. Weight is attached to bottom of roller shade fabric forming lower edge of adjustable roller shade. Movable pulley is fixedly attached to one end of the roller shade fabric winding shaft. The traction ropes are wound around the movable pulley and the four winders. Each of the four winders is driven by a driving motor respectively and the four winders rotate in different combination of directions to raise or lower both upper edge and lower edge of adjustable roller shade, resulting the adjustable roller shade to be opened or closed freely from both upper and lower edges of the adjustable roller shade.
