Description

Drive to operate the leaf of a door or window
The invention relates to a drive for a door leaf or a window sash, according to Claim 1.
An electro-hydraulic drive for door leaves, having a cylinder-and-piston device, the piston-operating space of which on the inlet side is connected to the pressure side of an electrically driven hydraulic pump and on the outlet side to a hydraulic reservoir is known from DE 32 02 966 C2. The piston-operating space receives in a displaceable manner a piston which is coupled by way of a drive to the leaf and is impinged in the closing direction of the leaf by means of a closer spring. By switching on the hydraulic pump, the piston is advanced counter to the force of the closer spring, on account of which the leaf reaches the open position. A pressure-compensation element which receives volumetric changes of the hydraulic fluid may be provided in the hydraulic reservoir. EP 2 075 398 A2 discloses a drive for a window sash or a door leaf, having a housing and a piston which is impinged by a spring and is disposed in the housing. The housing is filled with a hydraulic fluid which serves for controlling the movement of the piston when the sash or leaf is opened or closed, to which end overflow channels and valves are provided. In order to compensate for the volumetric change of the hydraulic fluid, for example as a result of thermal expansion, a gas volume which is enclosed by an elastic enveloping body and on the jacket sleeve of which the pressure of the hydraulic fluid acts is provided. The complex sealing of the elastic enveloping body which may also become permeable as a result of aging is disadvantageous. DE 34 11 189 A1 discloses a drive which is configured as a door closing unit, having a damping piston which is supported on a lifter cam disc and which has a cavity serving as a reservoir cylinder in which a pressure-compensation piston which is loaded by a pressure spring in the direction towards the cavity of the damping piston and forms a pressure-compensation unit for the pressure means kept in the door closing unit is disposed. In the event of rising pressure within the door drive, the pressure-compensation piston is displaced toward the pressure spring. Here, sealing of the air volume in the cavity of the damping piston by way of the pressure-compensation piston is problematic.
The invention is based on the object of providing a simple, reliable pressure-compensation unit for a drive for a door leaf or a window sash.
The object is achieved by the features of Claim 1.
The dependent claims form advantageous potential design embodiments of the invention. Electro-hydraulic drives for a door leaf or a window sash may be configured as drives which are disposed on the door frame or on the door leaf or the window sash, respectively, and may have a piston with a toothing which meshes with the pinion of an offtake shaft. Here, a linkage or a slider arm which is guided in a slider rail and which for opening and closing interacts with the leaf or sash, respectively, is disposed in a known manner on the offtake shaft. The piston in the housing filled with the hydraulic fluid is impinged by a spring, Furthermore, overflow channels and valves for the hydraulic fluid, which serve for controlling the behaviour of the drive, are disposed in the drive.
The proposed pressure-compensation unit for compensating temperature-related volumetric changes of the hydraulic fluid is disposed in the hydraulic reservoir.
The hydraulic pump suctions the hydraulic fluid out of the hydraulic reservoir. In the assembled state of the drive, the longitudinal extent of the hydraulic reservoir is oriented in at least an almost horizontal manner. In order to suction off the hydraulic fluid, a flexible intake hose which on its open end has a neck which is at least so heavy that said neck always comes to lie on the bottom of the hydraulic reservoir, protrudes into the hydraulic reservoir. The recirculation of the hydraulic fluid from the receiving space of the piston and the closer spring back into the hydraulic reservoir is performed by way of one or a plurality of hydraulic channel(s) which open(s) out in a centric manner with respect to the vertical extent into the hydraulic reservoir. A gas volume, for example air, is provided in the hydraulic reservoir which, on account of its low density in comparison to the hydraulic fluid, is located above the hydraulic channels opening thereinto. On account thereof, the gas volume is trapped in the hydraulic reservoir. Since gases are compressible or expandable, respectively, a temperature-related change in the volume of the hydraulic fluid is compensated.
The pressure-compensation unit acts in a positionally independent manner, on account of which the drive is suited to alternative assembly modes. This positional independence is important in the case of an alternative assembly on the hinge side or the side which is opposite the hinge of a door, or in the case of an optional assembly on the leaf or else on the door frame, since the drive here also has to be installable when rotated by 180°.
In the following an exemplary embodiment in the drawing is explained in more detail by means of the figures, in which:
Fig. 1 shows a horizontal longitudinal section through an electro-hydraulic drive;
Fig. 2 shows a longitudinal section through the hydraulic reservoir in a first assembly mode of the drive;
Fig. 3 shows a longitudinal section through the hydraulic reservoir in a second assembly mode of the drive.
In Fig. 1 an electro-hydraulically configured drive 1 is illustrated in cross section. The drive 1 comprises a housing 2 having a piston 7 which is guided in a displaceable manner in the cylindrical receiving space 5 and in the toothing of which the pinion of an offtake shaft 8 meshes. A closer spring 6 is axially disposed between an end face of the piston 3 and a right end of the housing 2.
The receiving space 5 of the housing 2 is entirely filled with hydraulic fluid 9, since the hydraulic system of the drive 1 was bled during filling.
On account of bleeding, uncontrolled closing of the door leaf, which is disadvantageous to the user and is caused by an otherwise existent air cushion in the receiving space 5 of the housing 2, is avoided. That is to say that, disadvantageously, on account of the compressible air cushion, initially no resistance or only very little resistance would then be perceptible on the leaf, until the air cushion has been compressed to the point where the hydraulic system of the drive becomes effective. However, on account of the absent air cushion in the event of a complete filling with hydraulic fluid, there is disadvantageously an increase in pressure in the housing 2 of the drive 1 when the temperature rises.
In order for the piston 3 to be able to execute its displacement movement in the housing 2 while being damped by the hydraulic fluid 9, hydraulic channels 10 are provided in the housing 2. Further hydraulic channels 10, in which valves for controlling the behaviour of the drive 1 may be disposed, may also be provided. The drive 1 furthermore is provided with a hydraulic pump 3 and a motor 4, on account of which automatic operation is possible when actuator elements for personal identification are used. The suction region of the hydraulic pump 3 is located in a hydraulic reservoir 11 which likewise communicates with the receiving space 5 via hydraulic channels 10. In the assembled state of the drive 1, the longitudinal extent of the hydraulic reservoir 11 is oriented in at least an almost horizontal manner. A lever arm or a linkage, respectively for opening and closing the door leaf is disposed on the offtake shaft 8 of the drive 1, said lever arm or linkage, for this purpose, being connected to the leaf in a manner known per se.
In order for the door to be opened, the piston 7, by way of the hydraulic pump 3 which is driven by means of the motor 4, is displaced in the direction of the closer spring 6, on account of which the latter is compressed. The energy which is stored on account thereof in the closer spring 6 is now available again in a reversal of the situation when closing the door leaf, to which end no operation by the motor 4 and the hydraulic pump 3 is required.
In Fig. 2 the hydraulic reservoir 11 is illustrated in longitudinal section. In the hydraulic reservoir 11, a suction element 13 for removing hydraulic fluid 9 is disposed on the bottom of the hydraulic reservoir 11. The suction element 13 is disposed on a connector of the hydraulic pump 3 and comprises a hose 14 and a neck 15. Alternatively, the neck 15 may also be directly connected in an articulated manner, for example by means of a ball joint, to the connector of the hydraulic pump 3. In order for the increase in pressure to be compensated, a gas volume 12 is provided in the hydraulic reservoir 11.
One of two potential assembly modes is shown in Fig. 2, such as is required for example for an alternative assembly of the drive 1 on the side opposite the hinges or the hinge side, respectively, or else in the case of doors with two leaves. The second potential assembly mode is an assembly rotated by 180°, as is illustrated in Fig. 3. In relation to the arrangement shown in Fig. 2, the motor 4 then is located on the left, made possible on account of the continuous offtake shaft 8 which allows for connection interfaces for the linkage and the slider arm, respectively, in order for the door leaf to be attached on both sides of the housing 2.
The hydraulic channels 10 which open into the hydraulic reservoir 11 are disposed so as to be approximately centrical in the hydraulic reservoir 11. The gas volume 12 which is located above the hydraulic fluid 9 is selected such that at the lowest envisaged operating temperature said gas volume 12 at maximum reaches up to the hydraulic channels 10. This state is shown in Fig. 3. Fig. 2 shows a state having a temperature which is higher in comparison, wherein the volume of the hydraulic fluid 9 has increased, this having been compensated for by way of compression of the gas volume 12.
The suction element 13 is configured such that by way of its open end it always sinks to the bottom of the hydraulic reservoir 11. For this purpose, the suction element 13 is advantageously configured so as to be flexible, such that at least the neck 15 thereof, independently of the position of the drive 1 and corresponding to the assembly mode, always remains in the hydraulic fluid 9, on account of which no gas is suctioned by way of the hydraulic pump 3 from the gas volume 12 or makes its way via the hydraulic channels 10 into the receiving space 5. For this purpose, the comparatively heavy neck 15, which may be of metal, for example, is secured to a flexible hose 14, on account of which, in order to remove hydraulic fluid 9, the neck 15, following gravity, comes to rest in the hydraulic fluid 9 on the bottom of the hydraulic reservoir 11.
The ratio of hose 14 and neck 15 is in this case not specified. The neck 15 may also be arranged as a short end piece on a then somewhat longer hose 14.
