Abstract:
A door operator includes a first component having a right-hand thread, a second component having a left-hand thread, and a plug-in or rotatable coupling having two complementary threads. The first and second compartments are interconnected to each other by the coupling when the right-hand thread of the first compartment and the left-hand thread of the second compartment engage the respective complementary threads of the coupling.
Abstract:
A system for use with a emergency exit door, comprising: a door opener including a stationary actuator with a movable distal arm for pushing the door open; a door strike mountable to a door frame having an opening to receive a latch of the emergency exit door, the electric door strike including a gate having a locked condition and a release condition; a controller connected to the door opener and the door strike; a remote activator having a triggered condition, which provides a signal to the controller when the remote activator is triggered, to unlock the gate and then the door opener, to open the emergency exit door.
Abstract:
A linear gate drive assembly with a drive rail connectable to a gate panel. A linear drive portion having a toothed drive surface is coupled to a first drive surface of the drive rail and has teeth thereon with a first rolling tooth profile. A drive wheel is attached to one drive motor and engages the first drive surface to impart an axial drive force on the drive rail. Another drive wheel is attached to another drive motor and engages the second drive surface. The second drive wheel has teeth that mate with the first teeth and that define another rolling tooth profile corresponding to the first rolling tooth profile. Rotation of the second drive wheel imparts axial and normal forces via a rolling teeth interface for moving the drive rail and the gate panel.
Abstract:
A ceiling track system including a guiding rail, in which at least one wall element is received and an encasing element that is affixed to the guiding rail. A long leg extends in a vertical joining direction and has a latching geometry, into which a latching hook can be latched such that the encasing element is affixed to the guiding rail in a self-retaining manner. The long leg has a web with a projection. The guiding rail has a groove into which the projection engages for the purpose of self-retaining the encasing element. Adjacent to the groove the guiding rail has a screw reception into which a screw element is screwable by which a clamping action is achieved. The screw reception is at an angle with regard to the vertical joining direction.
Abstract:
An at least partially preassembled and packaged movable partition system is disclosed. The at least partially preassembled and packaged movable partition system includes a shipping box including a plurality of pocket walls defining a pocket therein, at least a portion of a track located within the pocket, the at least a portion of the track coupled to at least one pocket wall of the plurality of pocket walls, and a door coupled with the at least a portion of the track. Methods of packaging and installing an at least partially preassembled and packaged movable partition system are further disclosed herein.
Abstract:
A drive system for operating and for guiding a wall element, in particular for a room partitioning wall system, with a carriage unit, which is guided to be longitudinally movable in a guiding rail (3). The wall element is pivotably attached to the carriage unit.
Abstract:
A mechanical arm system for opening a door includes an actuator assembly having an output shaft and an arm driven by the output shaft so as to move the door from a closed position toward an open position. The arm is free from contact with the door when the door moves from the open position to the closed position. The actuator assembly is mounted to a support member adjacent the door. The arm extends between the output shaft and the door. The arm may be moveable between a position in which the arm contacts the door in the open position and a retracted position in which the arm is free from contact with the door in the closed position. The arm may be moved to the retracted position before the door reaches the open position so as to abort the opening of the door.
Abstract:
A multiple position ball stud assembly for a closure strut supporting a closure pivotally attached adjacent to an opening, and a method of operation, is disclosed. The ball stud assembly may comprise a ball stud and a ball stud actuator. The ball stud may have a socket portion mounted on a closure lift assist strut and a guide pin extending from the socket portion. The ball stud actuator assembly may include a housing, a guide for receiving the guide pin, and an actuator for moving the guide pin along the guide to thereby cause the ball stud to move relative to the housing. The multiple position ball stud assembly may also include a control assembly that engages the actuator for selectively causing the actuator to move the guide pin along the guide.
Abstract:
An ejection device for a furniture component moveably housed in or against a furniture body. The ejection device includes a swivellably housed lever. A first castor is attached to a free end of the lever, and a second castor is attached to the lever at a distance from the free end.
Abstract:
The invention relates to an energy guide chain system comprising an energy guide chain for guiding cables, hoses or the like between a stationary and a movable connection point, an entrainment portion to which the energy guide chain is connected by way of the movable connection point, and a guide channel which has a hollow profile with a passage extending in the longitudinal direction for the entrainment portion, wherein the energy guide chain is guided in the guide passage in the longitudinal direction thereof in the form of two runs which are guided in mutually parallel relationship and which are connected to each other by way of a deflection region, as well as a sliding door system for a vehicle having the energy guide chain system. In order to achieve easy and reliable guidance of cables, hoses or the like in at least two directions, it is proposed that the entrainment portion has a movable arm which projects from the guide channel with a fastening side for connection to an apparatus movable relative to the guide channel, wherein the spacing between the fastening side and the guide channel is variable in a travel component in transverse relationship with the longitudinal direction of the guide channel.
