Definitions

  • the invention relates to a drive, e.g. Door closer, for a wing of a door, a window or the like.
  • the drive housing is preferably provided for concealed installation in a door leaf or in a door frame. At least two closer springs are arranged in the drive housing, which are acted upon when opening or closing the leaf and are designed as energy stores for automatically closing or opening the leaf, with each closer spring being supported on a separate piston, known as a spring piston, guided in the drive housing .
  • a preferably hydraulic damping device for damping the closing and / or opening movement of the wing is arranged in the drive housing.
  • an output member preferably designed as a closer shaft, which cooperates with the closer springs and / or with the damping device via a gear and is coupled to a force-transmitting linkage.
  • DE 195 26 061 A1 describes a particularly narrow door closer for concealed installation in a door leaf or door frame.
  • the door closer has a piston system with two pistons working in opposite directions and two separate closer springs.
  • the two pistons are coupled to the closer shaft via a crank mechanism arranged on an eccentric disc.
  • the crank mechanism allows the use of particularly narrow springs.
  • the design of the crank mechanism is relatively complex.
  • a separately designed damping device is required, which in turn takes up more installation space.
  • DE-PS 61 34 44 describes a door closer with two separate closer springs, which interact in opposite directions via a pinion with a pinion arranged on the closer shaft.
  • the two closer springs are arranged in one plane on opposite sides of the closer shaft.
  • a common damping device is accommodated in the door closer housing, which interacts with the closer shaft.
  • the Schi manergeophuse has a relatively large height.
  • the object of the invention is to construct a particularly narrow door closer with a damping device, which is also of particularly compact construction.
  • the object is achieved according to the invention by the subject matter of claim 1.
  • the closer springs with spring pistons are arranged offset to one another in the direction of the closer axis
  • the closer springs can be arranged in a plane arranged parallel to the door plane - i.e. parallel to the plane in which the door closer housing is mounted on or in the door leaf or on or in the door frame - be arranged one above the other.
  • the closer springs with spring pistons are arranged offset parallel to one another in a direction parallel to the door plane
  • the closer springs and spring pistons lie in two planes arranged parallel to one another at a distance and parallel to the door plane.
  • the closer springs with spring pistons can both lie in one plane parallel to the door plane.
  • the closer springs can be axially aligned with one another or more or less offset from one another, whereby the overall height can also be reduced
  • the spring piston chambers are arranged on opposite sides of the closer shaft, a particularly significant reduction in the overall height can be achieved; for this purpose the offset between the central axes of the piston spaces is made smaller than their diameter, i.e. When viewed in the axial direction of the housing, the cross sections of the piston chambers partially overlap.
  • the overall lengths are 250 mm to 350 mm for arrangements with closer springs on one side of the closer shaft and 350 mm to 550 mm for arrangements with closer springs arranged opposite the closer shaft.
  • the two closer springs can be of identical design or can also have different lengths, diameters or spring constants. At least one of the closer springs can interact with a device for adjusting the spring force, with which the bias of the closer spring can be varied.
  • two further piston chambers with a smaller diameter can advantageously be formed in the housing for receiving two damping pistons.
  • a spring piston chamber and a damping piston chamber at the same height on opposite sides of the closer shaft.
  • the damping piston chambers are also designed to be shorter than the spring piston chambers, so that there is free space in the housing for accommodating further assemblies following the damping piston chambers.
  • Such assemblies can be, for example, an electromagnetic valve actuation and / or the valve itself, a locking device, a sensor element, a hydraulically connectable additional spring or the like.
  • cam disks can be arranged one above the other on the closer shaft, the cam disks being mirror-symmetrical to their longitudinal axis.
  • the cam disc is heart-shaped, so that the ratio between the spring piston and the closer shaft changes depending on the angular position of the closer shaft; It is hereby achieved that the torque on the closer shaft remains almost constant or slightly decreases with increasing opening angle despite increasing spring force - there is therefore a reduction ratio with the opening angle - so that when using a sliding arm linkage when opening the The door gives a drastically decreasing torque towards larger opening angles.
  • the gearbox can be used as a pinion, e.g. with a pinion on the closer shaft side and a rack on the piston side.
  • the pitch curve of the pinion can be designed such that the effective lever arm of the pinion becomes smaller as the opening angle increases; here too there is a transmission ratio that decreases with the opening angle.
  • One spring piston and one damping piston each interact with the same lifting disc.
  • the interaction preferably takes place via a force transmission roller or damping roller, which are mounted on an axle bolt at the front end of the respective piston.
  • pinions and pinions can also be provided for coupling between the piston and the closer shaft. It is also possible to interpose a preferably hydraulic transmission between the spring piston and the cam plate or pinion or between the damping piston and the cam plate or pinion.
  • the closer shaft can be formed in two parts within the housing into two axially connected sections, the interaction of the two closer shaft sections taking place via a gear. In this way, the rotary movement of the closer shaft can be reduced or translated, which enables the use of differently designed closer springs.
  • the pressure-side piston chambers of the two damping pistons are coupled to one another via one or more hydraulic channels.
  • the pressureless piston chambers of the two damping pistons are also hydraulically connected to one another via the receiving chamber of the closer shaft. This makes it possible to provide only one valve for adjusting the damping and only one valve for adjusting the end stop for both damping pistons.
  • the valves are easily accessible on the top of the housing.
  • the door closer has a locking device in the open position of the door.
  • the damping pistons can be hydraulically locked in the open position of the door, e.g. operated by an electromagnetic valve.
  • Another variant provides a free-wheel function for the door closer. This freewheeling function is achieved by locking the closer springs in the tensioned state. In addition, the damping is switched off hydraulically. The Spring pistons can then be moved freely by the closer springs without restoring forces.
  • Versions with a freewheel function can have a locking device for the closer spring, e.g. hydraulic valve, and have a freewheel in the area of the closer shaft or a force-transmitting linkage connected to it.
  • a locking device for the closer spring e.g. hydraulic valve
  • the drive is modular. Different, universally combinable modules can be provided, e.g. Spring and damping components, spring components, damping components, locking components or drive components; e.g. the required closing force can be achieved by the preferably axial alignment of spring components.
  • the output shafts e.g. coupling via belt, pull rope, chain or push rod.
  • the door closer can also be provided for use on swing doors, with the door leaf opening in both directions.
  • an overlying installation of such door closers is also possible, with optical advantages resulting from the small structural depth.
  • a door closer is sunk in the floor area near the door axis of rotation.
  • the closer shaft which is arranged parallel to the floor level, is then connected to an angular gear with the door rotation axis or to a sliding arm arranged in the lower door area.
  • the angular gear can be designed as a module which can be connected to the door closer housing.

Abstract

L'invention concerne un mécanisme d'entraînement, conçu pour être le plus étroit possible, notamment un ferme-porte automatique (1), qui doit être incorporé à un vantail de porte ou à un encadrement de porte de façon non visible. Le ferme-porte automatique de l'invention (1) présente un axe de fermeture (2), sur lequel sont placées deux cames de commande (22a, 22b), décalées l'une par rapport à l'autre. Deux pistons à ressort (3a, 3b), équipés chacun d'un ressort de fermeture (4a, 4b), sont respectivement placés de chaque côté de l'axe de fermeture (2), également décalés en hauteur l'un par rapport à l'autre. Dans cet agencement, chaque piston à ressort (3a, 3b) coopère avec une came de commande (22a, 22b). Deux pistons d'amortissement (5a, 5b) de plus faible diamètre sont placés respectivement en face de chacun des pistons à ressort (3a, 3b), et coopèrent aussi avec les cames de commande (22a, 22b).
