Abstract:
The present disclosure includes systems, methods, and articles of manufacture for controlling a door. In various embodiments, exemplary systems may include a controller that may initialize and/or reset a limit count. A controller may initialize and/or reset a limit count in response to detection by a first position sensor of a first target. A controller may further initialize and/or reset a limit count by incrementing the limit count in response to a signal from a gear tooth sensor until a second position sensor detects a second target, whereupon the controller may store the limit count.
Abstract:
A frame member is provided for a structure. The frame member includes a generally flat, elongated first surface having an elongated slot therein extending along an axis. The slot is defined by first and second converging sidewalls lying in corresponding planes which are at acute angles to the first surface. A first diverging outer abutment wall is generally perpendicular to the first converging sidewall and a second diverging outer abutment wall is generally perpendicular to the second converging sidewall. A first diverging inner abutment wall is generally perpendicular to the second converging sidewall and a second diverging inner abutment wall is generally perpendicular to the first converging sidewall.
Abstract:
A door assembly includes a track, a track header, a fixed door panel, at least two sliding door panels, a pivot mechanism, and a lock arrangement. The sliding door panels are slidably movable on the track between (1) a closed position wherein the sliding door panels are extended across the track, and (2) an open position wherein the sliding door panels are constructed and arranged to be in a compact, overlapping relationship with each other and the fixed door panel. The pivot mechanism is constructed and arranged to enable pivotal movement of the track with fixed door panel and the two sliding door panels mounted thereon about a pivot axis from a normal configuration to a breakaway configuration. The lock arrangement is constructed and arranged to releasably lock the track with respect to the track header to prevent pivotal movement of the track away from the normal configuration.
Abstract:
A revolving door that has a drive, which is operatively connected to a turnstile of the revolving door and rotationally drives the turnstile. The drive includes a drive motor configured as a multipole electro-motor, the axis of rotation thereof extending parallel or coaxially to the axis of rotation of the turnstile and has a height of equal to or smaller than 80 mm.
Abstract:
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.
Abstract:
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.
Abstract:
Apparatus and techniques for bracing roll down doors of a building against severe winds and against burglary use a vertical bar mounted in a quick release fashion to a plate mounted to the floor by the door and a mounting bracket, mounted to the building, which receives a bracket mounted to the vertical bar which slides into the bracket. The equipment can be provided in a kit form for easy installation by a homeowner, authorized dealer or contractor. The apparatus can be quickly and easily installed for security or when a threat of severe wind is anticipated and easily removed when the threat has passed.
Abstract:
An explosion-resisting window with a window frame and a sash frame, which accommodates a panel and is mounted in hinges on the window frame, so as to be tiltable, the sash frame nesting in the window frame in closed position. In order to obviate the need for an outer front glazing of armored glass while guaranteeing adequate safety against explosion shocks and permit the function of continuous ventilation if necessary in open position of the sash frame, the panel is made of armored glass and the window is provided with at least one tilt-limiting element, by means of which explosion-induced tilting of the sash frame in the hinges beyond a tilt-limit position can be resisted. There is at least one shift-limiting element, by means of which explosion-induced shifting of the sash frame perpendicular to a tilt axis in the hinges can be resisted.
Abstract:
Apparatus and methods for generating repeatable closure of a volume measurement chamber are provided. More particularly, in one embodiment of the present invention, a dual articulating hinge is used to affix a chamber door to a volume measurement chamber, providing repeatable closure of a chamber door. In another embodiment of the invention, a laterally compliant magnetic latch is used to fasten a chamber door to a volume measurement chamber. In a third embodiment, a chamber door lid is mounted to a hinge bar via a ball joint, allowing the chamber door lid to self center about the chamber opening.
Abstract:
Retractable doors 22 to a washing chamber 20 of a washer 10 open automatically to allow a load to be processed to be wheeled into the chamber. The doors are fitted with blowout panels 42, 44. In an emergency, a worker trapped in the washing chamber can escape by pushing the blowout panels outward. A tilting floor assembly 70 includes a floor 76 supported on a frame 74 and a lifting mechanism 90 for selectively raising and lowering a side of the frame to tilt the floor. The floor is tilted automatically during a cleaning cycle to allow cleaning fluids to drain from the load, then leveled before opening of the doors for ease of removal of the load.
