Abstract:
A tilt-up door for a building having an opening, a pair of substantially vertically juxtaposed members, cam surfaces extending laterally from the vertical members at the upper portion and a door sized to span the opening. The door can be pivotally coupled to carriages arranged for vertical movement along the vertical members and can have cam followers extending laterally from the upper portion of the door to contact the cam surfaces. Hydraulic actuators can be connected to the carriages to move the carriages along the vertical members. When the actuator or actuators are operated to move the carriages vertically along the members the cam followers can move along the cam surfaces to tilt the door to a horizontal position as the door is moved vertically upward into an open raised position.
Abstract:
A sliding door with reversible hand configurations can include a plurality of mounting locations along a top and a bottom edge thereof. The plurality of mounting locations can be configured to allow the sliding door to selectively hang and operate according to multiple orientations in order to satisfy site-specific handedness requirements. In one implementation, the sliding door includes a door frame and mounting hardware for selectively mounting the sliding door to a roller track affixed near the upper portion of a doorway.
Abstract:
A roller assembly (1) for supporting a panel (62), including a coupling (5) for connecting the assembly (1) to the panel (62) and a roller (3) for transferring the weight load of the panel (62) to a sill (30), the roller (3) being received in the sill (30) and oriented for rotation about an axis (38) which extends in a direction of the weight load. The invention also relates to a sill and panel assembly for use with the roller assembly.
Abstract:
A locking device for locking a leaf of a leaf installation has first and second locking elements with respective first and latching elements. The second latching element is located at an end facing the first latching element and capable of a latching operative engagement with the first latching element. The second locking element is stationarily disposed relative to the leaf installation. The first locking element is disposed with regard to the leaf to move correspondingly to a movement of the leaf, so that the first locking element is moved translationally into a locking position towards the second locking element and away from the second locking element into an unlocking position. One of the locking elements has an activating element operable to allow for the latching operative engagement between the latching elements in a blocking position and to prevent the latching operative engagement in a release position.
Abstract:
A personnel access door assembly of an opposing wing of a mine ventilation door. The personnel access door includes a frame including a top portion, a bottom portion, a first post portion and a second post portion, the top frame portion and the bottom frame portion coupled to respective top and bottom ends of the first post and second post portions. The personnel access door further includes sets of trolley wheels affixed to the top or bottom of the frame to engage a top rail or bottom rail affixed on the opposing wing.
Abstract:
Disclosed is a window regulator that reduces thrust-down noises by minimizing the moment of rising even when the window glass reaches the lower edge, and improves the durability of an elastic member. The window regulator (10) is provided with: a carrier plate (12) that holds the window glass; a guide rail (11) that freely guides the carrier plate up and down; a direction switching member (13) disposed at the top end of the guide rail; inner cables (16, 17) that pass over the direction changing member, and are connected to the carrier plate (12); and a drive mechanism (14) that reciprocatingly drives the inner cables. An elastic member (28) is disposed on the lower edge of the carrier plate (12). A receiving section (27), which comes into contact with the elastic member (28) and controls the descent of the carrier plate, is disposed on the drive mechanism (14) housing (25). The receiving section (27) has an inclined surface (44) inclined in such a manner as to rise with increasing distance from the guide rail.
Abstract:
Insulated tracks for use with loading dock doors are disclosed herein. In one embodiment, an insulated door track configured in accordance with the present disclosure includes a first insulator, such as a plastic material, applied to a surface of the door track that extends adjacent to the loading dock door in the closed position. A second insulator, such as a radiant barrier comprised of a thin film of a reflective material, such as aluminum, can be applied to an opposing surface of the first insulator to prevent or at least reduce radiant energy losses through the track. A gap between the first insulator and the door jamb can be sealed with a third insulator, such as a suitable strip of foam.
Abstract:
A drive system for driving 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. The carriage unit has a roller carriage disposed within the guiding rail, and a drive unit disposed below the guiding rail. A guiding device is provided in the transition area between the roller carriage and the drive unit that cooperates with the guiding rail for guiding the carriage unit.
Abstract:
A motor vehicle window lifter with a twistable or bendable guide rail 3 on which a driver to be coupled with a window pane is shiftably mounted and which includes fastening points 51 with are connectable with fastening receptacles 41 of a carrier element 2. Between the fastening receptacles 41 of the carrier element 2 at least one supporting point 61 is provided. When bracing the fastening points 51 of the guide rail 3 with the fastening receptacles 41 of the carrier element 2, the guide rail 3 supports on the supporting point 61 and twisting of the initially straight guide rail 3 with a specified degree of twisting and/or bending of the guide rail 3 with a specified bending radius R is effected.
Abstract:
A roller door system includes a roller assembly configured to mount directly to a panel and move along a complementary upper guide. In particular, the roller assembly can be coupled to a coupling member embedded in the panel. The roller assembly, when coupled with the panel, can provide a smooth gliding motion for the panel.
