Abstract:
A power drive assembly (110) for controlling movement of a closure panel (102, 105) of a vehicle includes a closure panel (102, 105) that moves relative to the vehicle between open and closed positions, and a latch (108, 115) for cinching the closure panel (102, 105) to the vehicle. The drive assembly (110) includes an actuator (134), a first torque output (136) coupled to effect movement of the closure panel (102, 105), a second torque output (138) coupled to the latch (115), and a clutch assembly (114, 150) coupled between the actuator (134) and the torque outputs (136, 138) for selectively transferring torque between the actuator (134) and the torque outputs (136, 138).
Abstract:
A field assemblable panel door comprises a pair of metallic stiles each having an outer wall, a pair of side walls extending perpendicularly thereto and an engagement element on the inner surface of the outer wall which provides a bore. The side walls provide a first inwardly opening panel receiving channel therebetween, and a pair of flanges on one side wall provide a second panel receiving channel. A pair of metallic rails each have inner and outer side walls, and a base wall extends between the inner ends of the side walls to provide an outwardly opening channel, and the base wall provides a second inwardly opening channel. Corner connectors join the ends of the stiles and rails to form a rectangular frame. The connectors have an outer end wall overlying the ends of the rails and a body portion extending in the outwardly opening channel. A fastener seated in the corner connector engages in the bore of the engagement element in the adjacent stile, and a panel is seated in the opposed inwardly opening channels of the stiles and in the inwardly opening channel of at least one of the rails.
Abstract:

The door assembly includes at least one bottom roller mechanism fitted into a lower portion of a bottom rail. The bottom roller mechanism is adjustable and concealed within the bottom rail. The door assembly further includes at least one top roller mechanism fitted into an upper portion of a top rail. The top roller mechanism is concealed in the top rail.
Abstract:
A corner bracket assembly for use in an associated movable frame assembly is provided. The corner bracket assembly includes a first housing piece having upstanding coupling pins. A second housing piece has receiving pockets for connecting engagement with the coupling pins and defining a cavity therebetween. A roller assembly is received within the cavity. The roller assembly includes a roller housing, a threaded engaging portion defined in the roller housing, and a roller rotatably mounted within the roller housing. A threaded fastener is rotatably mounted between the first and second housing pieces and is in threaded engagement with the roller assembly. A track is defined between the first and second housing pieces and the roller assembly for linearly adjusting a position of the roller assembly in relation to the first and second housing pieces.
Abstract:
The invention relates to a damping device for movable furniture parts, for example for doors or drawers, comprising a piston or plunger which is slidably guided in a hollow body, e.g. a cylinder, with said piston or plunger being impinged upon by spring force into its pushed-out position. According to the invention, the hollow body comprises at least one section of a spiral-shaped stay of the internal screw thread, and/or the piston or plunger comprises at least one section of a spiral-shaped stay of the external screw thread. The stays of the screw threads are glidingly supported one on top of the other, or cams or journals of the hollow body or of the piston or plunger are supported on a screw-thread section of the other component. The pitch of the stays of the screw threads is greater than the pitch at which self-locking occurs.
Abstract:
An automatic closing door hinge, an automatic closing door mechanism, and a hinge of the automatic closing door mechanism, for smoothly opening a door or closing, with damping, a door. For example, an automatic door closing mechanism has a hinge having a pair of wing plates one of which has a cylinder in a circular cylindrical form received therein a piston, the other wing plate fixing an upper portion of an operation rod engaged with the piston, the piston being to be advanced and retracted through the operation rod associatively with a rotation of the other wing plate. The automatic closing door mechanism comprises a cam formed on the piston. An engaging part provided in the operation rod and movable in the cam. The cam and the engaging part engaging between the piston and the operation rod. A sphere arranged in a recess formed in an outer surface of the piston. A recess groove formed lengthwise in the cylinder. The sphere rolls along the recess groove, to allow the piston to slide within the cylinder. Impact upon door closing is to be damped by an action of air cushioning within the cylinder due to a return movement of the piston.
Abstract:
A hanger bar assembly for sliding doors used in transit cars has at least two separate coaxially oriented, preferably tubular bearing segments which can slidingly engage a cylindrical rod secured above an entry portal of a transit car. Each bearing segment contains bearing means such as a ball bushing bearing. The tubular bearing segments can be secured to a hanger bar at selected locations, taking into consideration such factors as the location of door hanger support points above an entry portal of the transit car, the location where the sliding door interfaces with an adjacent sliding door, the horizontal width of the door, and the distance that the door must travel along the cylindrical rod. Each of the bearing segments can be sealed at either end to reduce the likelihood of dirt and other contaminants entering the bearing segments.
Abstract:
Disclosed is an improved apparatus for opening and closing a door, comprising a hydraulic hinge and a spring-type hinge. The hydraulic hinge includes a rotary member having a housing, a piston guide placed inside the housing, a rotary shaft disposed inside the piston guide and a piston screwed with the rotary shaft, and a fixed member having a housing, a cylinder placed inside the housing and having an oil outlet formed therethrough for allowing oil to pass therethrough, an outflow part formed on the top surface of the cylinder and having a plurality of support protrusions formed thereon, a head mounted on the top surface of the cylinder and an adjusting bolt screwed with the head in such a manner as to form an oil circulating passage therein. The spring-type hinge includes a spring disposed therein for closing an opened door due to its compressive tension and an elevation part disposed therein to be rotatably elevated while being rotated and having a spring fixing part formed on the top surface thereof for allowing the lower end of the spring to be fixed thereto.
Abstract:
A powered operator assembly for moving an object along a linear axis and particularly for moving doors in a mass transit vehicle utilizing a helical drive member for moving and supporting an attached door panel. The helical drive engages a drive nut that is connected to one of the two door panel hanger assemblies. Each door panel hanger assembly is attached to the door panel and includes at least two rollers which engage the outer surface of a helical drive for motion along the drive axis. One end of such helical drive is connected to an electric prime mover with such prime mover mounted to a stationary bracket mounted to the door opening structure. The second end of the helical drive engages a bearing mounted to a stationary bracket mounted to the door opening structure.
Abstract:
A power sliding assembly for moving a windowpane within a track within a window frame between an open position and a closed position. The power sliding assembly includes a motor fixedly secured to the window frame. The motor generates a rotational force. The power sliding assembly also includes a lead screw that is operatively connected to the motor to translate the rotational force to axial movement. In addition, the power sliding assembly includes a bracket secured to the lead screw and the windowpane. The bracket travels with the lead screw as the lead screw is driven axially along the track to move the windowpane between the open and closed positions.
