Definitions

  • the invention relates to a drive for a wing of a window or a door according to the preamble of claim 1.
  • a drive which comprises a designed as a cylindrical tube housing and a linearly slidable in the bore of the housing working piston, in the rack meshes a drive pinion.
  • a predetermined fluid volume of a hydraulic fluid is present, wherein the volume change of the fluid due to thermal expansion is compensated by means of a gas volume acted upon by the fluid.
  • the compensating gas volume is enclosed by a flexible enveloping body, on the lateral surface of which the pressure of the hydraulic fluid is effective, whereby the enveloping body can be elastically deformed.
  • a wound drive spring for a spring drive is also arranged in the hollow cross-section of the enveloping body can be accommodated, but here the enveloping body is firmly connected to the working piston and is moved out in its Verschjeberison from the hollow cross-section of the drive spring.
  • the pressure surge of the hydraulic fluid acts directly on the flexible enveloping body, A surge tank for receiving the enveloping body is not provided and thus an impact on the implementation of the hydraulic pressure is not possible.
  • a door closer is described with an expansion chamber in which a deformable capsule lies in a receiving channel in which it can be lapped by the hydraulic fluid.
  • the amount of hydraulic fluid flowing is determined by a manually adjustable valve.
  • the reaction of the deformable capsule influenced by pressure surges or the ambient temperature is also predetermined.
  • the expansion chamber with the receiving channel and the valve is arranged laterally of the drive spring.
  • a door drive is also the DE 10 2004 031 936 A1 already to be taken as known.
  • the drive for a door closer comprises a cylindrical housing, in which a movement-coupled with the door leaf via a gearbox is linearly slidably guided.
  • hollow cylinder is divided into two hollow chambers. These hollow chambers are connected to each other in response to the position of the working piston by overflow, whereby the displaced hydraulic fluid can flow with damping of the movement of the working piston in dependence on its direction of movement from one to the other hollow chamber.
  • Both compression springs are designed as helical compression springs and provided with different winding diameter, whereby they are arranged to save space concentric with each other in the hollow cylinder.
  • the helical compression spring with the smaller coil diameter is axially guided during its compression and expansion of a guide sleeve, while the larger helical compression spring is slidably guided by the cylinder wall itself. When you release the door, this is pressed by the spring force of the synchronously expanding springs against the damping force of the overflowing hydraulic fluid back into its closed Stelung and thus automatically closed.
  • the closing springs made of steel ensure that the closing movement of the door largely independent of the ambient temperature can be done reliably by the drive.
  • a free gas volume should advantageously be present in the housing of the drive, so that the change in volume of the hydraulic fluid due to its thermal expansion can be compensated reliably, without resulting in leaks due to a pressure increase due to expansion of the hydraulic fluid. It may also interfere with the technical function by an uncontrolled air volume in the hydraulic system.
  • a drive for a door closer is known, which is acted upon in a cylinder sliding piston operated by mediation by the hydraulic fluid from a gas spring as a closing spring.
  • the displaced by the working piston hydraulic fluid passes during its opening stroke via an overflow channel in a separated from the rest of the cylinder chamber chamber in which a rubber-elastic, inflated with compressed air cushion is arranged.
  • This gas cushion is compressed by the hydraulic fluid flowing into the chamber, whereby the volume of the gas cushion is correspondingly reduced with increasing pressure of the gas cushion.
  • the gas cushion expands back to its original volume, wherein the hydraulic fluid flows out of the chamber into the cylinder and drives the working piston in the direction of its closing stroke to its end position.
  • the invention has for its object to provide a generic drive that can be designed while avoiding excessive pressure levels in the hydraulic system with great structural freedom, the comfort of the door drive is maintained.
  • the basic idea of the invention is based on the consideration of compensating for the volume change of the fluid in the closed fluid system as a result of temperature changes via a compensating means, which does not react to rapid pressure changes in the hydraulic system, but allows compensation of the volume change.
  • a compliant enveloping body with gas filling such as a rubber bladder, which communicates with the hydraulic system through a bore.
  • This enveloping body may have an overall relatively small volume, because although it can act to a small extent as a gas spring, but serves only the purpose of compensating for the temperature-dependent change in volume of the fluid. This allows the gas pressure in the envelope and its Volume should be correspondingly low. For a safe expansion of the enveloping body with decreasing fluid temperature can already be a low internal pressure of eg 1 bar sufficient. Also, the fluid system can be completely filled and vented.
  • the enveloping body consists of rubber-elastic material, which is inflated by the gas filling and compressed uniformly by the expanding fluid.
  • the enveloping body is protected against damage integrated into the fluid system of the drive.
  • it can be arranged within a fixed expansion tank.
  • a connecting channel, through which the fluid can flow into the interior of the expansion tank, can be advantageously formed as a throttle point.
  • the overflow can consist of a single bore with a correspondingly small diameter. This implements a high-pass filter for hydraulic systems. Ease of use is fully maintained, as pressure surges, such as opening the door, do not impact while slow pressure changes are compensated.
  • a sintered part with a correspondingly larger size may be provided instead of the bore, wherein the fluid-permeable pore spaces of the sintered part together form the connecting channel or the high-pass filter.
  • the overflow channel is arranged in a peripheral wall of a tubular receiving body, the sintered part can preferably be designed as a circumferential sintered ring or over a part of the circumference extending sintered ring segment.
  • the sintered part can advantageously be integrated in a lid or form a permeable sintered lid.
  • the compact expansion tank is arranged in the hollow cross-section of the spring winding and possibly also used for radial support or linear guidance of the coil spring surrounding it.
  • This advantageous arrangement possibility exists regardless of whether the spring drive is associated with a door closer for fire doors, a door opener for escape doors or a direction reversible spring drive for door operation of fire or escape doors.
  • Fig. 1 is designed as a door closer drive 10 can be seen in horizontal section.
  • the drive 10 comprises as main components designed as a cylindrical tube housing 11, a linearly sliding in the bore of the housing 11 working piston 12, in the rack a drive pinion 13 meshes, a helical compression spring 14, the axially between an annular end face of the working piston 12 and an opposite Ring end face of a spring plate 15 is supported, wherein the spring plate 15 axially to the working piston 12 along an adjusting screw 16 is guided, a housing cover 17 for completion at the left end and a housing cover 18 for completion at the right end of the housing 11 and a cylindrical expansion tank 19, which is arranged in the hollow cross-section of the helical compression spring 14.
  • the spring force is adjustable by the spring plate 15 along the adjusting screw 16 with an engagement arrangement not shown here from outside the housing 11 is adjustable.
  • a closing force indicator 22 may be arranged in the housing 11.
  • the hollow cylinder of the housing 11 is divided by the working piston 12 and the spring plate 15 into two hollow chambers.
  • the left hollow chamber is therefore limited by the housing cover 17 and piston 12, the right hollow chamber of the piston 12 and the housing cover 16. All cavities in the hollow chambers are completely filled with hydraulic fluid 20, since the hydraulic system of the drive 10 has been carefully vented after filling.
  • the working piston 12 can perform its stroke in the housing 11 under damping by the hydraulic fluid 20, not shown in the housing 11
  • Matterströmkanäle are formed with associated, adjustable valves.
  • 12 check valves 21 are arranged in the working piston, which allow directional overflow of hydraulic fluid 20.
  • valves and check valves 21 is a controlled overflow of hydraulic fluid 20 from the left into right hollow chamber of the housing 11 and vice versa, possible.
  • the rotation of the drive pinion 13 is formed by the fact that it is rotatably connected outside of the housing immovably held on the frame of a door or a window 11 with a crank arm, not shown, which is guided for example in a slide rail.
  • the in Fig. 1 only schematically indicated compensation tank 19 is mounted in the hollow cross-section of the spring winding so that it the compression and expansion the helical compression spring 14 can not hinder and also causes no noise.
  • the expansion tank 19 serves primarily for the purpose of compensating for the change in volume of the hydraulic fluid 20 as a result of thermal expansion by means of a gas volume pressurized by the hydraulic fluid 20, which is enclosed by a flexible enveloping body.
  • the supporting structure advantageously consists of a tubular, cylindrical receiving body 23, for example made of impact-resistant plastic material or metal, which is closed at its ends by a respective screw cap 24.
  • the screw cap 24 is screwed onto an associated thread on the outer circumference of the receiving body 23.
  • a cylindrical plug 25 is depressed to an associated sealing seat, which is formed by an annular groove 26 with a rectangular cross-section. This annular groove 26 is end cut out of the inner circumference of the receiving body 23 and thus forms a stepped shoulder in the pipe wall.
  • a hose portion 27 In the sealed by the annular groove 26 sealing seat an end portion of a hose portion 27 is clamped, which consists of rubber-elastic plastic material and extends over the entire length of the receiving body 23. Both ends of the hose portion 27 are thus sealed in each case via a fastening arrangement of screw cap 24, plug 25 and annular groove 26 with respect to the associated peripheral portion of the receiving body 23.
  • a valve In one of the plugs 25, a valve, not shown, is integrated, through which the enveloping body bounded on the circumference by the hose section 27 is filled by a pump with a gaseous medium, such as air 28, and inflated to a pressure of about 1 bar. As a result, the inflated tube section 27 rests against the entire circumference of the receiving body 23 with a somewhat radial bias on the entire surface.
  • the wall of the receiving body 23 is penetrated by a connecting channel 29 in the middle length region.
  • the connecting channel 29 has only a relatively small free flow cross-section on, whereby he acts as a throttle point and forms a high-pass filter for the hydraulic fluid.
  • the connecting channel 29 may also be formed by a sintered insert 30 having a multiplicity of fine, gas-permeable pores.
  • the sintered insert 30 is embedded in the receiving body 23, in particular injected in a receiving body 23 in the form of a plastic body, and, depending on the size of the pore spaces in the sintered material, extends over a partial circumference or even the entire circumference of the receiving body 23.
  • hydraulic fluid 20 can penetrate into the expansion tank 19 through the connecting channel 29 and uniformly compress the air cushion in the hose section 27, with the hollow cross section of the hose section 27 being correspondingly reduced. If the system pressure drops again, the air cushion expands in the hose section 27 and the hose section 27 abuts against the inner circumference of the receiving body 23. The hydraulic fluid 20 is thus pushed out of the expansion tank 19 through the connecting channel 29 again.
  • compensating tank 19 'agrees with the principle of operation with that of the above-described expansion tank 19, which is why only the differences are explained in more detail.
  • a supporting structure of the surge tank 19 'a receiving body 23' is provided, which is closed pot-like manner at one end.
  • a bellows 27' is arranged made of rubber-elastic plastic, the cup-shaped and adapted with its open edge side near the bottom of the pot receiving body 23 'with circumferential sealing on the inner circumference of the receiving body 23' adapted to the hollow cross-section of the receiving body 23 ' , Due to this arrangement, the bellows 27 'is compressed in pressurization by the hydraulic fluid 20 is not in the radial direction, but in the axial direction and expands upon pressure drop of the hydraulic fluid 20 in the opposite axial direction.
  • the connection channel 29 'designed as a throttle point is therefore arranged on the open front side of the receiving body 23'.
  • the surge tank 19 may, if necessary, under mirror-symmetrical design of its end regions, similar to the expansion tank 19 be designed to be elongated so that it can be integrated to save space in the winding cavity of the helical compression spring 14.
