Abstract:
A device for adjusting a window regulator in a vehicle door, having - a profiled base element (110) positionable on a lower section of the vehicle door and provided with a first elongate hole (111b) in its lower side and a second elongate hole (111a) in its upper side. A slider (112) slidingly moves within the base element (110) and includes a hole (113) aligned with the first elongate hole (111b). A screw extends through the hole (113) in the slider and the first elongate hole (111b) aligned therewith. A bolt (116) is fixedly attachable to the window regulator extending through the second elongate hole (111a) and includes a threaded rod engaging the threading of screw (114). The screw (114) can be turned from a first position, in which it does not engage the slider (112), to a second position, in which it engages the slider (112) with the first screw end (114b). The device provides for simple compensation of tolerances in connection with the vehicle door and for the window regulator.
Abstract:
An automatic closing door hinge, an automatic closing door mechanism, and the hinge of the automatic closing door mechanism allowing a smooth door opening operation and a smooth door closing operation while absorbing a shock; the automatic closing door mechanism, comprising a piston fitted into a tubular cylinder provided, for example, in one of a pair of slats, an operation rod having an upper part fixed to the other slat engaged with the piston, and a hinge interlocked to the rotating motion of the other slat through the operation rod for moving the piston forward and backward, wherein the piston is engaged with the operation rod by a cam formed on the piston and an engagement part movable in a cam formed on the operation rod, spherical bodies are disposed in a recessed part formed in the outer surface of the piston, and the spherical bodies are rolled along the recessed groove formed longitudinally in the inside wall of the cylinder, whereby the piston can be slidably moved in the cylinder and an impact caused when a door is closed can be absorbed by an air cushioning action in the cylinder by the returning operation of the piston.
Abstract:
A window (10) for use in buildings or other enclosed areas is structured to open horizontally relative to the buildings or window casement and comprises a screen-like enclosure between the window casement and the window frame (16) which limits the amount of moisture or dust that can enter through the window when in an open position. Further, the window (10) is particularly structured to provide light, ventilation and an unobstructed view while providing a high degree of security to prevent breakage or burglary.
Abstract:
A rigid corner connector (1) for a door (2) having a frame with stiles (6) and rails (8) seating a panel (2) therein, includes a bracket (14) having a generally planar body portion (24) with perpendicular sidewalls (26) defining a channel and having inwardly extending lips (28) along an intermediate portion. An end wall (30) extends between the sidewalls at one end thereof, and an end flange (32) at the other end extending in the opposite direction and having tabs (34) engaging the rail (8) thereon. The sidewalls (26) also have outwardly extending side flanges (42, 44) adjacent their ends, and the side flange (42) adjacent the end flange (32) has a tab (66) engagable in the end of the stile. The other side flange (44) has a tab (50) engagable in a slot (10) in the wall of the stile (6). A roller mounting member (16) is slidably seated in the bracket for sliding movement on the bracket and it transfers loads to the end wall (30). A roller (18) is rotatably mounted on the mounting member, and a detent tab (98) seated in a channel in the roller mounting member limits the movement of the mounting member on the bracket.
Abstract:
A garage door operator (10) is disclosed to have a front coupling (60) for a threaded screw (30) of the operator (10) and the rotor of the motor (20). The coupling (60) includes a first coupling device (62) that is a unitary coupling member with opposing recesses (68B, 68A) for receiving each of the rotor shaft (26F) and an end portion (74) of the screw (30). The unitary coupling member thereby connects the screw (30) to the motor (20) for torque transmission from the motor. The second coupling device includes a thrust containment device (92) that is supported on the screw (30), and an intermediate assembly (90) disposed between the thrust containment device and an end portion (44) of the guide rail (40) of the door operator. A retainer component (94) of the intermediate assembly restricts expansion of the thrust containment device.
Abstract:
Rotary locks used on transit vehicle doors (2) when opened and closed by a rotating helical door drive member (40). In a preferred embodiment, a first lock utilizes a negative thread portion (51) of the helical drive (40). A second lock utilizes a rotating lock pawl (22) and stop (23). The drive (40) and lock can be used to operate door systems with and without separate door hangers. Compensation for camber variations in car structure is provided through the use of spherical mounts or drive member journals (35, 38).
Abstract:
An overhead door assembly for opening and closing a door opening comprises a plurality of door sections (10) having hinges (12) for hingedly joining the door sections (10) together. A pivot (26) on an upper end region of each door section (10) pivotally connects a tandem arm (28). Each tandem arm (28) has at opposite ends thereof a rotatably mounted roller (20). A lowermost door section has a roller (21) rotatably mounted at the lowermost region of the door section. Two lead arms (29) each have a first end pivotally connected to the pivot (26) of the uppermost door section and an opposite end having a rotatably mounted roller (25). An axle (14) is rotatably mounted above the door opening (22) and having springs (16) for urging the axle (14) to rotate in opposite senses. Drums (15) are fixedly mounted on the axle (14) and aligned with each side of the door opening (22). Two cables (19), each extend from the lowermost door section about the drum (15) and extending to the opposite end of the lead arm (29). Two guides (24) extend upwardly along each side of the door opening (22) for guiding the door sections (10) as the door travels to open and close the door opening (22). A motor (32) drives the axle (14) in one sense tensioning the cable (19) extending from the lowermost door section for opening the door and for driving the axle (14) in an opposite sense tensioning the cable (19) extending at the opposite end of the lead arm (29) for closing the door.
Abstract:
A runner assembly of the type comprising a support (19) and a yoke (20), carrying a wheel (21), at least one part of which protrudes with respect to support (19) in at least one direction corresponding to its direction of use, said wheel being pivot mounted on a support (19) about axis (22) parallel to axis (23) of said wheel (21). According to the invention, elastic means (36) are associated with the yoke (20) which, when they are under stress, apply an elastic force to the yoke (20) in the direction of use of the wheel (21) mounted in it. Application for sliding doors, particularly for cupboards.
