A roller carriage for the reception of a sliding door includes a roller module for a displaceable affixing at a roller running path and a basic body for the attachment to the sliding door. The roller carriage includes a lift-off protection device for the protection against removal of the roller module out of the displaceable affixing at the roller running path. The lift-off protection device includes a lift-off protection element which is supported to be movable between a protection position and a release position, as well as an arresting device for an arresting of the lift-off protection element at least in the protection position.

The system includes a series of operable louvers mounted on a four-sided frame and connected on each side to the operating mechanism that allows for easy opening and closing of the louvers. Every part of the system that is exposing to the exterior of the building is separated from the interior part of the system by a low heat conductivity material as a thermal barrier. Each operable louver is composing of a four-sided main frame, two panes of glass (inner and outer) and a coupling mechanism on each side that connects to the operating mechanism. The main frame acts as the thermal break as well as a system that absorbs the energy created when an outside object impacts the window from the outside. The system incorporates sealing devices between all moving parts to eliminate water and air infiltration. The operating system allows for easy opening and closing of the window by rotating each louver with the crank mechanism assisted by springs.

A system and method of a latching hinge system including a first leaf, a second leaf pivotally coupled to the first leaf, a coupler mounted on a first latch surface of the first leaf and a receiver mounted on a second latch surface of the second leaf wherein at least one of the coupler and the receiver has a corresponding orientation for latching the first leaf and the second leaf at a corresponding first angle.

A component part assembly adapted for use with a window or door screen is provided. One or more component parts are provided which add functionality to a window or door screen. An attachment mechanism is provided for attaching the one or more component parts to a screen frame of the screen subsequent to manufacture of the screen. The one or more component parts may include at least one of a locking component, a guide component, a slide component, a handle component, a pull tab component, a roller component, a wheel component, a hinge component, a pivot cam component, a weather stripping component, a seal component, a frame component, a barcode component, an RFID component, a flexible attachment component, or the like. The screen frame may be a flexible screen frame or a rigid screen frame, and may be for a full or half window screen or a door screen.

A multi-panel overhead stacking door which allows for the addition of multiple panels across an opening width. A vertical extrusion acts a guide for the panel above and/or below it. The vertical extrusion serves as a moving guide which thereby allows for the relatively easy addition of multiple panels. At each end of the door is a series of formed parts that are attached to the ends of the end panels and movably maintained with door guides. The assembled door is driven by, for example, a driven shaft, positioned at the top of or above the door opening. The shaft comprises drums to windingly and unwindingly receive a lifting member. The lifting member runs from the drum to the bottom panel assembly behind each vertical extrusion.

An elevating-type shelter door enables operators to easily open and close in a short period of time, is highly water-tight, and has an excellent durability. A shelter door opens and closes an opening portion when a door body ascends and descends along a guide rail by means of an elevating device. The opening portion is provided on a ceiling of a shelter body. The shelter body is defines an interior space which serves as an evacuation space in an underground. A main body has a central convex portion which slidably fits to the opening portion along an inclination direction in which both the opening portion and the guide rail inclines. An elevating stand is slidably fixed to move along a rest column. The elevating stand is located above the opening portion when the door body is fully ascended and located in the interior space when the opening portion is closed.

An omni-directional connection assembly broadly includes a hinge pin and one or more connection brackets. The hinge pin comprises a base section, a pair of primary walls, and a pair of opposed projections. The primary walls form a primary slot therebetween for receiving an engagement portion of a first panel therein. The opposed projections are spaced from the primary walls and form elongated passageways for allowing the primary walls to bend slightly outward for receiving the engagement portion of the first panel. The connection brackets are U-shaped for being positioned over the hinge pin and including flanges for attaching the connection brackets to a second panel. The first and second panels are then connected together at angles of between 0 and 180 degrees or more.

A door hoist includes a bracket, drive sprocket, ring gear, hub assembly, set of planetary gears, and governor shaft. The drive sprocket has a drive sprocket axis. The ring gear is fastened to the drive sprocket. The ring gear has a ring gear axis that is in alignment with the drive sprocket axis. The hub assembly includes a connector to receive a door drive shaft and secure the door drive shaft in a fixed rotational alignment with the hub assembly. The set of planetary gears is rotationally mounted to the hub assembly. The set of planetary gears is configured to mate with the ring gear. The governor shaft includes a sun gear, brake assembly, and link. The sun gear is configured to mate with the set of planetary gears. The brake assembly has an engaged position and a disengaged position. The sun gear is rotationally fixed relative to the bracket in response to the brake assembly being in the engaged position. In response to the brake assembly being in the disengaged position, rotation of the sun gear is unfixed relative to the bracket. The link secures the brake assembly in the engaged position. The link is configured to melt in response to an ambient temperature exceeding a predetermined temperature.

A corner piece is provided for interconnecting frame members. The corner piece includes a first plate member defining an inner face, an opposite outer face, a first side face, an opposite second side face, and an end face. The first plate member including a bolt-receiving bore therethrough. A second plate member defines an inner face contiguous with the inner face of the first plate member, an outer face, a first side face, an opposite second side face, and an end face. The second plate member includes a bolt-receiving bore extending between the inner face and the outer face thereof along a first axis generally parallel to the inner face of the first plate member.
