A base slat pry stopper, such as a base slat locking bracket, for locking a rolling shutter curtain covering an opening of a structure is disclosed. The base slat pry stopper may include a bracket base plate mounted to an opening bottom wall on an interior side of the shutter curtain, and a base slat engagement portion extending upward from the bracket base plate and above a top surface of the opening bottom wall. When the shutter curtain is unrolled to cover the opening, the base slat engagement portion engages the base slat to prevent the base slat from deflecting upward away from the opening bottom wall when a force applied from an exterior side of the shutter curtain causes the base slat to deflect toward the interior side of the structure and the shutter curtain. The base slat pry stopper may be permanently or removably installed.

A locking system for a rolling shutter comprises a housing, a body, and a lock bar. The housing has a longitudinal housing channel. The body has a body channel, and is positioned in and moveable transversely within the housing channel. The lock bar is positioned within the body channel, and is moveable longitudinally to the body and housing between a locked position extending away from the body and an unlocked position retracted toward the body. The movement of the body within the housing channel is coupled to the movement of the lock bar between the locked and unlocked positions.

In one embodiment, a guide system includes a first member configured to be fixed to a structure. A coupling element is fixed to the first member. A second member is moveable relative to the first member. The second member is configured to receive the coupling element to couple the first member to the second member. There is a channel between the first member and the second member when the first member is coupled to the second member. The channel is configured to receive a portion of a closure.

A locking mechanism for use with a door structure having a corrugated surface includes a main body having a corrugated surface. The locking mechanism is configured to be adjustable between an unlocked position where the corrugated surface of the main body is not nested relative to the corrugated surface of the door structure and a locked position where the corrugated surface of the main body is nested relative to the corrugated surface of the door structure. The corrugated surface of the main body includes a plurality of engagement surfaces. Each of the engagement surfaces is configured to resist movement and/or deformation of the door structure with respect to a direction of movement of the door structure associated with the door structure being moved from a closed position towards an open position.

The support connector system includes a first shade band having a support connector and a lock that receives the support connector. The lock includes a first opening in a first position, wherein the first opening is configured to receive the support connector and configured to restrict rotation of the support connector. The lock includes a second opening in a second position, wherein the second opening is configured to receive the support connector and configured to allow rotation of the support connector.

The window shade system may comprise a support connector and/or a first shade band. An adjustment arm may interface with the support connector and/or the first shade band. The adjustment device interfaces with the adjustment arm, wherein in response to adjusting the adjustment device, the adjustment arm is configured to rotate and adjust the support connector and/or the first shade band to an adjusted position.

The window shade system may comprise shade fabric with a first portion and a second portion. A rod may be configured to include the second portion of the shade fabric rolled around the rod. A hembar may receive the rod within a compartment of the hembar, wherein the compartment includes a first surface and a second surface, and wherein the rod and the second portion of the shade fabric rolled around the rod are supported between the first surface and the second surface.

A roller shade assembly includes a roller tube including a first end opposite a second end, the roller tube defining an opening longitudinally extending between the first and second ends, and an idler assembly partially received by the opening at the first end, the idler assembly including an idler housing, a plunger received by the idler housing, and a biasing member configured to apply a biasing force onto the plunger, wherein the plunger is configured to slide relative to the idler housing, and the plunger is configured to selectively engage a bracket member.

A closure locking design is presented that is more resistant to a displacement/dislodgement force. A closure end strip is fixed to a closure end and received by a closure guide first section. A rotatable tube and hook assembly run vertically within a closure guide second section. When rotated to a locking position a hook member of the tube and hook assembly rotates through a slot cut in the guide and through a cutout in the closure end strip to restrictively engage the closure.

An improved roller shade system provides increased support, additional adjustments and/or increased safety. The slip plate allows the brake to slip forward and minimize damage to the clutch spring when a user pulls too hard on the hembar. The center drive mechanism extends through a bracket to allow the drive shaft to distribute power in both directions and drive two shade tube simultaneously. The tube adapter absorbs force from the spinning shade tube to minimize damage to the other components and the bead chain. The sprocket has a back wall supporting the sprocket, allowing the sprocket 130 to rest on the back flange of the sun gear to minimize pressure on the gears. An adjustment arm is adjusted to help level the shade band. The shade bands may be removed without disturbing the other shade bands in the system. A height of a hembar may be adjusted by rotating a rod within the hembar.
