Definitions

  • the invention relates to a drive for a door, window or the like with the features of the preamble of claim 1, preferably a manual door closer.
  • Hydraulic door closers with closer springs are known. During the opening movement by hand, the closer spring is compressed. This results in a disadvantageous opening resistance. The closing movement then takes place automatically under the action of the closer spring. In practice, it is important that the closing torque is relatively high shortly before the closing position is reached in order to be able to overpress the lock latch. With conventional door closers, this has the consequence that the opening resistance in the area of small opening angles is particularly high and disturbing.
  • the invention has for its object to develop a drive of the type mentioned so that a higher ease of access is obtained and a safe closing is also guaranteed.
  • a door closer is to be created, which has a non-disturbing opening resistance when opening, so that a pleasant manual opening is possible and a safe automatic closing, eg. B. is guaranteed by overcoming the lock latch.
  • the different torque curve provided by the invention when opening and closing means that the path-dependent torque curve when opening and closing is different, i. H.
  • the path dependency of the opening torque, which represents the opening resistance, is different from the path dependency of the closing torque, which forms the automatic closing effect.
  • a control device can be provided for switching over the torque characteristic at a certain door rotation angle, whereby it can be realized that at a certain door rotation angle there is a transition from one torque characteristic to another torque characteristic.
  • the control device can be switched in such a way that one torque characteristic becomes effective in the opening direction and the other torque characteristic takes effect in the closing direction.
  • the energy store interacts with a control curve.
  • the control curve can preferably have separate curve sections for opening and closing, which can be switched in and out of effect. It is particularly advantageous if the curve sections are automatically controlled when opening or closing, preferably switched forcibly, e.g. B. be released or blocked.
  • the control curve can be formed on a cam disc and can cooperate directly or indirectly with the energy store, for. B. via an intermediate pressure piece.
  • Preferred embodiments of this principle can be designed as a door closer with a cam gear.
  • the control curve is formed on a cam, preferably two cams being present, namely a first cam with a first control curve which forms the opening cam and a second cam with a second control curve which forms the closing cam.
  • Particularly advantageous features of such exemplary embodiments are specified in claims 15 to 24.
  • control curve is designed as a control slot or control recess and interacts directly or indirectly with the energy store.
  • Particularly advantageous features of such designs result from claims 8 to 10. They can be designed as so-called switch sleeve closers.
  • the energy store is designed as a pneumatic or hydraulic pressure store and that different torque characteristics also occur here when opening and closing. Particular features of such designs are mentioned in claims 11 to 14.
  • the NO contacts shown all have a different torque characteristic when closing than when opening.
  • the door closer of Figures 1 to 5 has a switching sleeve device with special control cams for power transmission, the control curve for opening and closing run differently.
  • the control cams are switchable and are called switching pin tracks in the following.
  • the locking mechanism can be integrated in the door hinge.
  • a spring 3 When opening the door, i. H. when the door leaf or door leaf 50 is swung open, a spring 3 is tensioned via three switching pins 2 mounted in needle sleeves 1. For ease of understanding, only the movement sequence of a switching pin is considered below.
  • the switching sleeve 4 is concentric in the movement sleeve 5.
  • a different path-force curve is achieved by switching between the switching pin tracks 6 and 7.
  • the switching pins because of the predetermined direction of rotation of the door
  • the switching pins inevitably run on the flatter tracks 6 of the movement sleeve.
  • the track 8 on the shift sleeve runs steeper than the corresponding track 6 on the motion sleeve
  • the shift sleeve is rotated by the shift pin relative to the motion sleeve. If the door is opened beyond the switchover angle (here ⁇ / 16), the switching edge 9 blocks the switch pin's path back into the flat path.
  • the bow spring 11 is attached between the two sleeves.
  • the coil spring 3 is tensioned over the pressure plate 12 by the switching pins.
  • the pressure plate is secured by the plate 13 against rotation relative to the bearing pin 15 by the plate 13 engaging in an axial longitudinal groove in the bearing pin 15.
  • the bearing pin 15 can be stationary, ie fixed to the frame and the sleeve 5 with the door leaf 50 can be fixed.
  • the coil spring 3 acts as a closer spring.
  • the three radially directed switching pins 2 engage in the switching pin tracks in the sleeves, they are moved downwards when the sleeves 5, 4 rotate, vertically when opening and upwards when closing, with compression or relaxation of the closer spring 3.
  • the force is transmitted between the closer spring 3 and door leaf 50 by the switching pins 2 interacting with the edges of the switching pin tracks.
  • the steeper the switching pin path the greater the resulting force component in the circumferential direction of the sleeve 5, which determines the torque.
  • the steep section is preferably at a door angle of less than 90 degrees, in particular less than 40 degrees.
  • the apex of the turn forms the switchover point, in the present case at 40 degrees of rotation.
  • the door closer in FIGS. 6 and 7 has two cam-shaped cams, namely an opening cam 16 and a closing cam 17.
  • the gear is a cam gear with a switchable characteristic.
  • the compression spring 14 serves as a closer spring.
  • the pressure piece 19 cooperating with the compression spring 14 bears against the opening cam 16 at a).
  • the compression spring 14 is tensioned via the pressure piece 19.
  • the closing cam 17 serves only as a guide for the pressure piece.
  • the pressure piece is pressed down by the switching spring 60 onto the closing cam 17 as soon as it reaches the switchover point b).
  • the opening and closing cams have the same radius. The further course of the closing movement is controlled by the closing cam 17. From the switching point b), this has a smaller radius than the opening cam 16 in this area.
  • the desired path-force curve can be achieved by appropriate shaping of the cams.
  • Opening and closing cams have the same radius b) in the end position (closed door).
  • the pressure piece is pushed back onto the opening cam by a suitable mechanism after reaching the end position.
  • the compression spring 14 acts as a closer spring.
  • the cams form the output side of the door closer.
  • You can be connected to a closer shaft, e.g. B. rigid.
  • the axis of the closer shaft can be aligned with the axis of rotation A of the cams.
  • the closer shaft can be connected to the door leaf directly or via a force-transmitting linkage.
  • the cam device shown can be connected to a damping device, not shown, for. B. also attacking the closer shaft.
  • the cam device and the damping device can be arranged in a common housing, for example as in a conventional floor closer.
  • the door closer according to the principle in Figure 9 works in a corresponding manner.
  • the energy store 90 is connected to a piston-cylinder unit with a smaller effective cross section, a valve 91a is interposed.
  • the piston is connected to a piston of a second piston-cylinder unit 92, e.g. B. via a piston rod.
  • An overflow line 93 connects the two cylinders.
  • the small piston cylinder 91 acts when opening and closing.
  • the larger piston cylinder 92 is switched on at the end of the closing movement close to zero degrees of door rotation angle.
  • FIGS. 8 and 9 Sufficient energy for falling into the lock does not have to be stored again with every smallest opening operation.
  • the pressure accumulator is completely filled by repeatedly opening the door.
  • the complete closing of the door is achieved by a second cylinder (or enlargement of the first) that is active near zero closing angle.
  • the system works like an air pump. When opened, energy is added to the storage and stored there.
  • the memory is filled by opening it several times. As soon as the accumulator is filled, the opening resistance is minimal. Relatively little energy may have to be consumed from the memory to close, especially if closing takes place relatively slowly.
  • the pistons of the piston-cylinder systems are coupled to the door in a geared manner, e.g. B. to drive a shaft that forms the closer shaft.
  • the piston rods in FIG. 8 can be coupled to one another in terms of gears.
  • the energy store can also have an additional energy supply for recharging.
  • the torque characteristic curve when opening is different than when closing.
  • the torque characteristics shown in FIG. 11 are obtained. This result is obtained from the path / force curve present there, which is different when opening and closing, as shown in FIG. 10.
  • the closing torque is the same as the opening torque and remains as low until shortly before the closing position, in the present case at 8 degrees door angle. There, the closing torque jumps to a value that is significantly higher than the opening torque. The high closing moment just before the closed position ensures that the door closes firmly and the door latch is overpressed. If the door angle is even smaller immediately shortly before the end position, the closing torque can drop again to a value that keeps the door in the closed position.
  • the opening torque and thus the opening resistance over the entire angular range is relatively low, especially with no door angles - unlike conventional door closers - there is no high opening resistance.
  • This torque curve is only an example. In the exemplary embodiment in FIGS. 1 to 5, it can be set by appropriately selecting the parameters, in particular designing the control curve — this means correspondingly setting a varying transmission ratio and specifically differently when opening and closing.
  • the door closers according to FIGS. 12 to 42 have two cam-shaped cams, namely an opening cam 16 and a closing cam 17.
  • a switching device ensures that the opening torque characteristic is controlled by the opening cam 16 and the closing torque characteristic is controlled by the closing cam 17. Due to the different contour and the lever arms of both cams acting differently, a different opening and closing torque curve is achieved on the closer shaft 18.
  • FIG. 33 The arrangement in a door closer, preferably a floor door closer, is shown in FIG. 33. It can be seen there that the pressure roller 19 interacts with the opening cam 16 and the closing cam 17.
  • the pressure roller 19 interacts with a closing mechanism, not shown, which can be arranged to the right of the pressure roller 19 in FIG. 33 and in a conventional manner a closing spring and a damping device, e.g. B. with hydraulic piston-cylinder unit with damping pistons.
  • the cam device 16, 17, closer shaft 18 and pressure roller 19 and the aforementioned other locking mechanism are arranged in a housing, preferably cast housing 49.
  • the technical-functional details of the switchable cam device are described below with reference to FIGS. 12 ff.
  • the opening cam 16 shown in FIGS. 12 and 13 is non-positively connected to the closer shaft 18 of the door closer and cannot rotate relative to the closer shaft.
  • the opening cam has a cylindrical recess 20 which is concentric with the receiving bore 21 for the closer shaft.
  • the closing cam shown in FIGS. 15 and 16 fits with the cylindrical part of its outer contour in a form-fitting manner in the recess 20.
  • FIGS. 16 and 17 show how the closing cam is inserted in the opening cam.
  • the closing cam 17 can rotate in the opening cam 16 about the closer shaft 18.
  • the opening cam is firmly connected to the closer shaft.
  • the two cams have different outer contours up to a certain angle, which determines the switchover point between the opening and closing torque characteristics. This angle is 50 °, for example.
  • the locking cam From the edge 23a, the locking cam has a cylindrical outer contour which is concentric with the bore 28 (cf. FIG. 14).
  • Figures 18 to 20 show the interaction of opening and closing cam with the pressure roller 19 at different positions of the door.
  • the pressure roller 19 is acted upon from its right side with the spring force of the closer spring; this spring force is symbolized in FIGS. 18 to 20 by a black arrow.
  • Figure 18 shows the position of the cams and the pressure roller with the door closed.
  • the opening cam 16 connected to the closer shaft rests with the tips of its control surfaces 22 on the pressure roller and thus holds the door firmly in the rest position.
  • the closing cam 17 also rests with its control surfaces 23 on the pressure roller.
  • FIGS. 21 and 22 show the closing spring mechanism.
  • the leg spring lies concentrically around the disk 37 pushed onto the closer shaft 18 and is supported at each end against a bolt 26.
  • the bolts 26 are each pressed into an axial bore in the opening or closing cam.
  • FIG. 21 shows the position of the opening and closing cams and the leg spring 27 when the door is closed.
  • Figure 22 shows the position of the opening and closing cams and the leg spring with an opening angle of the door of less than 50 °.
  • the torsion spring is tensioned by rotating the closing cam in relation to the opening cam.
  • the spring tension creates a restoring moment that tries to turn the two cams back into the starting position (see FIG. 21).
  • FIG. 19 shows the rotation of the cams when the door is opened by an angle of less than 50 °.
  • a rotary movement (shown here in the clockwise direction) is transmitted to the opening cam 16 connected to the closer shaft via the closer shaft 18.
  • the opening cam slides with its control surface 22 over the pressure roller 19.
  • the pressure roller is pushed to the right by the control surface and compresses the closer spring (not shown here).
  • leg spring 27 is tensioned by turning the opening cam 16 (see FIG. 22).
  • the closing cam 17 is pressed by the tension of the leg spring with its control surface 23 against the pressure roller and cannot turn back into its starting position (FIG. 21). This creates a relative rotation of the closing cam to the opening cam.
  • the closing cam 17 lifts off the pressure roller.
  • the tension of the leg spring 27 rotates it back into its starting position relative to the opening cam 16.
  • the pressure roller 19 is only moved further to the right by the outer contour of the opening cam; the closer spring is further compressed.
  • the opening cam is non-positively connected to the closing cam by means of a switching pin 25, so that the two can no longer turn against each other.
  • This locking mechanism is explained in more detail below.
  • FIGs 23 to 26 The operation of the switching pin 25 is shown in Figures 23 to 26.
  • Figure 23 shows the position of the switching pin when the door is closed.
  • the switching pin 25 is located only in the opening cam 16, therefore the closing cam 17 has no non-positive connection to the opening cam (except via the leg spring 27).
  • FIG. 24 shows how the closing cam 17 rotates relative to the opening cam when the door is opened (cf. also FIG. 19). Since the relative rotation of the cams to one another obscures the bore 28, the switching bolt cannot be pressed into the closing cam by the switching force B. The switching mechanism and switching forces are explained below.
  • Figure 25 shows the switching process with a door opening angle of 50 °.
  • the closing cam 17 is turned back into its starting position relative to the opening cam 16 by the pretensioning of the leg spring 27 (compare FIGS. 19 and 20).
  • the switching bolt is pushed into the bore 28 of the locking cam by the switching force B.
  • FIG. 26 shows how the bolt is clamped between the opening and closing cam bores due to the closing torque. A force F can thus be applied to it without shifting.

  • Figure 28 shows a cross section through the switching mechanism.
  • the left end of the guide rod 29 is guided axially displaceably in the end plate 30.
  • the guide rod has a shoulder 31.
  • the blocking spring 32 which is arranged concentrically with the guide rod, presses with its right end on the shoulder 31 and with its left end on the end plate 30.

  • the switching pin has an axial bore, with which it is axially displaceably guided on the guide rod.
  • Figures 29 to 32 show the operation of the switching mechanism.
  • Figure 29 shows the switching mechanism with the door closed (see also Figures 23 and 35).
  • the closer spring presses on the pressure roller 19 on the threaded sleeve 33 and pushes the guide rod 29 into its left end position.
  • the blocking spring 32 is pressed and compressed by the shoulder 31 against the end plate 30.
  • the locking cam 17 can rotate about the closer shaft 18.
  • FIG. 30 shows the switching mechanism at a door opening angle ⁇ 50 °.
  • the closing cam 17 is rotated relative to the opening cam 16 (cf. also FIG. 24). Since in this position the pressure roller 19 is no longer in contact with the threaded sleeve 33, the blocking spring 32 pushes the switching pin 35 to the right until its outer surface 36 abuts the locking cam. The locking cam 17 can continue to rotate about the closer shaft 18.
  • Figure 31 shows the switching mechanism with a door opening angle> 50 °.
  • the closing cam 17 was rotated back into its starting position relative to the opening cam 16 by the leg spring (cf. also FIG. 25). In this position, the blocking spring 32 can push the switching pin 35 into the closing cam 17. This creates a positive and positive connection between the opening and closing cams.
  • FIG. 32 shows the switching mechanism at a door opening angle during the closing process shortly before the door is finally closed.
  • the pressure roller 19 has already pushed the switching mechanism back over the threaded sleeve 33 to the left. Due to the moment acting on the locking cam, the switching pin 35 is clamped in this position (see FIG. 26); therefore the release spring 34 cannot push it back to the left.
  • FIG. 33 shows the arrangement of the opening and closing cam and the switching mechanism in the installed state in the door closer with the door closed, the remaining closing mechanism interacting with the pressure roller 19 not being shown, but being able to be designed in a conventional manner, as mentioned at the beginning.
  • Figure 34 shows a section through the switching mechanism with the door closed. It can be seen how the guide rod 29 and the switching pin 35 are pushed to the left by the pressure roller 19.

  • the closing cam 17 loses contact with the pressure roller 19 at the switching opening angle predetermined by the cam shape (here 57 °)
  • the closing cam is rotated back into its starting position relative to the opening cam (cf. also FIGS. 19 and 20).
  • the switching pin 35 can now turn again and is rotated by the prestressed spring leg 43.
  • the cylindrical outer contour of the switching pin now engages in the recess 47 of the locking cam. This creates a positive and positive connection between the opening and closing cams.
  • the closing cam can no longer rotate relative to the opening cam.
  • Figure 40 shows the position of the cams 16 and 17 and the switching pin 35 when closing the door, here at 30 ° opening angle.
  • the spring leg 43 slides with its end over the cam track 44 and thereby holds the switching pin in its rotated position. This means that the opening and closing cams remain connected to each other in a positive and non-positive manner.
  • the pressure roller 19 rolls over the outer contour of the locking cam. (see also Figure 20).
  • FIG. 41 shows the position of the cams 16 and 17 and the switching bolt 35 when the door is closed, here at an opening angle of approximately 4 °.
  • the pressure roller 19 rolls over the button 23 of the closing cam 17.
  • the compressive force of the closing spring acts on the pressure roller 19 via the spring rocker 40.
  • a torque is introduced into the closing cam 17 via the button 23 and forwarded via the switching pin 35 into the opening cam 16 connected to the closer shaft.
  • Figure 42 shows the position of the cams 16 and 17 and the switching pin 25 when the door is closed, here at an opening angle of approximately 1.8 °.
  • the spring leg 45 is biased.
  • the clamping pin 35 between the opening and closing cam is released and the switching pin is released due to the pretension Leg spring turned back to its starting position (see Figures 36 and 37).
