Abstract:
An arm, forming a linkage arm, includes: a first linkage arm part; and a second linkage arm part. The first linkage arm part is arranged with one end at a driven shaft of a swing leaf operator so as to be fixed with respect to rotation relative to the driven shaft, so that the swing leaf operator can swivel the first linkage arm part around a first end of the first linkage arm part, as a center point of a rotational axis of the first linkage arm part, the first linkage arm part being configured, at a second end of the first linkage arm part, to be arranged at a first end of the second linkage arm part, so as to be fixed with respect to rotation relative to the second linkage arm part.
Abstract:
A swing leaf operator having a closer portion is described. The closer portion has an output shaft, on which a cam disc is torsion-resistantly disposed, as well as a pressure roller. By way of an operational connection, a closer spring presses the pressure roller against a running surface of the cam disc. The pressure roller, with regard to an axial center of the output shaft, is disposed such that, during an opening or closing of a swing leaf coupled to the output shaft, the pressure roller is moved along a path. Due to the fact that the path bypasses the axial center of the output shaft and on account of the configuration of the running surface of the cam disc, in different modes of operation of the swing leaf operator at a respective opening angle of the swing leaf, a very similar or identical torque is respectively applied to the output shaft. Furthermore, the swing leaf operator has a drive motor, which is in operational connection with the output shaft.
Abstract:
The invention relates to a drive device for a sliding door or a sliding plug door of a passenger transportation vehicle, comprising at least one at least linearly movable runner (7) in order to move a door leaf fastened thereto, a motor (3) fastened to the runner (7) or to the passenger transportation vehicle, and a first gearbox (2, 5, 6) between the motor (3) and runner (7) in order to effect at least the longitudinal displacement of the runner, characterized in that at least two fastening options (13, 14), which differ in the arrangement ratios of the first gearbox and motor, are provided between the motor and the first gearbox.
Abstract:
This disclosure relates to an electrically actuated door holder and release for the multi-point holding of a pivoted door at selected door opening angles, and for the release of a held door either electrically or in response to manual override. The door holder and release includes a rotatable spindle adapted to be connected to a pivoted door which is either push or pull-side mounted. The holder and release comprises a spindle gear assembly having a pair of male spline gears with each gear having a circular ring of splineways forming a series of male projecting keys. A pair of cams, each having cam lobes defining detent segments with each cam having a circular hole internally grooved to mate with the projecting keys of spline gear, is mounted on the shaft. A pair of springs yieldingly hold the cams into mating positions with associated spline gears to rotate therewith. A double lever having a common pivot or fulcrum carries a roller which follows the cams. The lever may be electromagnetically actuated and released to effect a door hold and release, or alternatively, the lever may be manually overridden. The selected hold-open angles may be set and altered, without removal of the holder and release or the associated door closer from their fixed positions on a header frame and door, respectively. This function is attained by the arrangement of the cams on the spline gears in association with depressible springs which enable the cams to be manually adjusted without removal of any component except the housing cover.
Abstract:
An over-the-top type cabinet door prop unit is characterized in that it comprises a fitting case to be rigidly fitted to the inner surface of one of the lateral walls of the cabinet, a movable spring holder vertically movable relative to the fitting case containing it and urged downward by compression springs, a link arm pivotably linked at the upper end to the movable spring holder by a pivot pin and a swing arm swingable around an arm spindle located in a lower portion of the fitting case and having a base section arranged around the arm spindle and linked to the lower end of said link arm by a link pin and an arm section extending from the base section and pivotably linked at the distal end thereof by an anchor pin to an anchor pin bearing secured to the over-the-top type cabinet door and that the pivot where the link arm and the base section of the swing arm is linked by the link pin is located closer to the cabinet door relative to the vertical axial line connecting the pivot pin and the arm spindle when the over-the-top type cabinet door is closed and moved onto the vertical axial line in the initial stages of the opening motion of the cabinet door and then further away from the cabinet door relative to the vertical axial line in the subsequent stages of the opening motion of the cabinet door until the cabinet door is placed on the top wall of the cabinet.
Abstract:
Apparatus is are disclosed for selective alteration and control of door movement modes, the apparatus being primarily non-hydraulic and incorporated with a known mechanism which is functional independently from the apparatus in one mode of operation and which includes a piston for controlling door closing characteristics by selected fluid flow within the mechanism. The apparatus includes a motor driven lead screw having a linearly movable shuttle unit mounted thereon, the shuttle unit being positioned relative to the piston of the mechanism to accommodate nonattached contact with the piston to urge the piston, when the shuttle unit is moved, in a direction that will at least provide selective assistance with door opening in another mode of operation.
Abstract:
