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:
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:
To provide a movable body driving device which has simple structure and is capable of moving a movable body in a certain direction and automatic drawer equipment. A movable body driving device is provided which comprises a roller 12 as a rotary member which is rotatably supported on an inner frame 11 as a supporting member and a motor 13 for rotating the roller 12. The roller 12 is brought in contact with the movable body, which is adapted to be movable in a certain direction, with predetermined force using elastic force of coil springs 21, 22, 23 as elastic members. The movable body is moved by frictional force between the movable body and the roller 12. Automatic drawer equipment employing the movable body driving device as its drawer driving mechanism is also provided.
Abstract:
A door system is driven by a motor. The door wings of this door system are guided by rollers (27) on a rail (10) secured in a door frame construction. The driving motor (30) of each door wing is secured onto an operating mechanism receiving the roller (27). It acts on the roller (27) in a positive manner or by friction-grip. The door system with the driving motor (30) fixedly arranged on the door wing and moving jointly with the door wing has a simpler structure as compared to known door systems, and can be manufactured and serviced at favorable cost.
Abstract:
A driving mechanism is disposed in the bottom of a door for driving the door and includes a reduction gearing and a motor fixed to the door, and a gear coupled to the reduction gearing and engaged with two shafts for rotatably supporting the wheels of the door so as to apply a downward force to the pinions in order to prevent the wheels moving upward away from the tracks. A retaining device is fixed to one of the tracks or fixed to the ground and has an opening for engaging with one of the pinions so as to maintain the door in place.
Abstract:
A sliding door apparatus for a railway platform, has a plurality of sliding doors provided along an edge of a railway platform, the plurality of sliding doors being, in a closed position, arranged continuously along a line; a sliding door shifting apparatus for shifting those of the sliding doors to be opened and closed into shifted positions parallel to the closed position of the plurality of sliding doors; opening/closing apparatus for opening and closing the sliding doors disposed at the shifted positions, the opening/closing apparatus being capable of moving the sliding doors in varying directions and amounts; and a logic apparatus for analyzing information regarding the positions and widths of entrances of a railway vehicle stopped at the platform, selecting the sliding doors to be shifted, and controlling the shifting and opening/closing of the sliding doors such that the sliding doors are opened and closed in conformity with the entrances of the railway vehicle.
Abstract:
A rolling nut in combination with a smooth shaft includes a plurality of bearing-like roller cages surrounding the shaft and having internal surfaces in contact with portions of the outer surface of the shaft and is operative for transforming a rotary movement of the shaft into thrust movement of the rolling nut. The rolling nut is open and is provided with a base plate formed with a plurality of pocket-shaped recesses in which the roller cages are partially inserted. The base plate is formed with similar recesses at both sides thereof so that the roller cages can be repositioned on either side of the plate to selectively adjust the roller cages to the left hand thread of the shaft or the right hand thread of the shaft.
Abstract:
A door operating device for operating by means of a DC motor the slide door of a slide door unit including an opening formed in the exterior panel of an automobile, the door designed to be arranged flush with the exterior panel when closed, guide rails extended along the upper frame, the lower frame of the opening and the outside surface of the exterior panel, respectively, and guide rollers for guiding the door along the guide rails. A first turnable arm is supported rotatably on the floor of the automobile, a second turnable arm is supported rotatably on the free end of the first turnable arm and a driving wheel is supported rotatably on the free end of the second turnable arm. The output torque of the motor is distributed into a torque for rotating the driving wheel and a torque for rotating the first turnable arm. When the motor is actuated with the door closing the opening of the exterior panel of the body of the automobile, first the door is swayed outside of the exterior panel of the body due to the rotatory motion of the first turnable arm and then the door is driven to slide along the exterior panel of the body by the agency of the frictional engagement of the driving wheel with a guide member secured to the inside surface of the door.
