Abstract:
A high-pressure mine door assembly for use in mine shafts configured with opposing wings, which enable the door to open and close quickly. The assembly includes a major hub and a minor hub positioned at or above the cap of the door assembly and coupled together via a connecting bar. A drive mechanism is coupled to the cap and the connecting bar, which facilitates the opening and closing of the wings of the door. The door assembly is configured in a 12-6 pitch orientation, requiring only a ⅔ rotation of the wings of the door assembly to fully open the door. Such a configuration also negates the effect of air pressure on operation of the door, as regardless of the direction of the airflow, with the airflow assisting one wing in opening and the other in closing.
Abstract:
An industrial sliding door for closing off a door opening in a wall of a structure includes a door panel that extends vertically for substantially the height of the door opening and horizontally between an inward edge of the door panel and an outward edge of the door panel and covers at least a portion of the door opening when the door is closed. The sliding door also includes a trolley assembly that is coupled to the door panel and that includes a track component. A shroud covers the trolley assembly and forms a rail for the track component. A drive assembly drives the trolley assembly to open and close the door opening and is positioned below a top panel of the shroud and behind a front panel of the shroud and between the trolley assembly and the wall.
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:
An improved sliding door for a vehicle comprises a guide rail (5) and a sliding carriage (6) which is mounted on the guide rail (5) in a longitudinally movable manner. The sliding door furthermore comprises a hinge stirrup (7), which is rotatably (8, 9) mounted on the sliding carriage (6) and on a body flange (4), a control lever (11) which is rotatably (12, 13) mounted on the sliding carriage (6) and on a body flange (4), a first intermediate lever (10) which is rotatably (17) mounted on the control lever (11), and a second intermediate lever (18) which is rotatably (19, 20) mounted on the first intermediate lever (10) and on the sliding carriage (6).
Abstract:
The invention relates to the adjusting and locking of the position of a guide rail for a movable window pane in a vehicle door. A device, a vehicle door equipped therewith and a tool provided for the adjusting and locking are disclosed. In the vehicle door, a first mounting plate mounted on the rail side and a second mounting plate mounted on the door side are provided, which are connected to one another by screw-fastenable mounting means. One of the mounting plates comprises an engaging element for an eccentric lever, which on rotation brings about a mutual translational displacement of the mounting plates in an adjusting (Y) direction.
Abstract:
Movable partition systems include a vertical alignment structure including at least one roller element coupled to a portion of a movable partition and a ramp configured to abut against the at least one roller element to vertically align the portion of the movable partition to engage with a strike plate. Methods of vertically aligning the movable partition include coupling at least one vertical alignment structure to the movable partition including coupling at least one structural frame member to the movable partition and coupling the at least one roller element to the at least one structural frame member and installing at least one ramp to an overhead structure configured to abut the at least one roller element and vertically align a leading end of the movable partition.
Abstract:
A mechanical reducer case for converting a motor torque into a drive torque for an opening is provided, the case forming a guide rail guiding the opening into a closed position or into an open position. Also disclosed is a motorized system for driving an opening including the preceding case and a method for manufacturing the preceding case including a half-shell.
Abstract:
A step unit includes: a step member which is provided with a pair of lower rails extending in an opening and closing direction of a slide door of the vehicle; and a rail plate member which is provided to a cutout formed in a part of either of the lower rails and which continuously connects the lower rails in the opening and closing direction. The step member is molded using a resin material and is provided with an insertion hole which vertically penetrates through the step member at a position corresponding to the cutout; and a support extension section which is extended from a side end of the cutout of the lower rail. The rail plate member is mounted to the step member by being inserted so as to penetrate through the insertion hole from above the step member.
Abstract:
A modular sliding door system includes a modular base with one or more lower tracks that may be removably connected in parallel, and ramps that may be connected to either side of a given lower track. The base may include one or more connectors that are configured to connect between two consecutive lower tracks. Each lower track has at least one longitudinal rail configured to receive a lower wheel assembly of a sliding door. The lower wheel assembly includes a lower wheel that has a transverse latch member disposed vertically below the lower wheel to slidably latch the lower wheel assembly to the lower track as the lower wheel rotates matingly on the longitudinal rail.
Abstract:
This is a design for a sliding glass door that provides the option to choose an opening right to left, or change to an opening left to right at anytime. The outside panel of the door can slide to either end of the opening and lock into place. The inside panel, sliding can slide to either end of the opening.
