Definitions

  • the invention relates to a drive for a wing of a door or a window according to the preamble of claim 1.
  • a drive for a sash of a door or a window is known, with a free-wheeling device, the drive being integrated in the sash or in the frame.
  • the drive has an actuating arm which is arranged on an output shaft of the drive and which is pivoted when the sash is actuated.
  • the actuating arm is arranged freely rotatably on the output shaft and has a driver which cooperates with a driver disk which is arranged non-rotatably on the output shaft.
  • the actuating arm In the area around the output shaft, the actuating arm has bores lying opposite one another, the driver being insertable into one of the bores to selectively determine the actuation direction of the drive.
  • the disadvantage here is that the freely movable sash may not stop in an open position, since the sash is already running towards its closed position due to a small force in the closing direction, which can occur, for example, from door hinges installed at an angle or a draft. This can be undesirable because the open door can be freely entered and should therefore remain open.
  • the invention is based on the object of creating a simple and inexpensive holding device to prevent the wing from closing.
  • Drives for the sash of a door or a window can rest on the sash or be integrated in the sash or in a frame or a frame.
  • the drive has an energy store, which stores the energy required for closing when the sash is opened.
  • an actuating arm is arranged between the drive and a slide rail mounted in or on the frame.
  • the drive-side end of the actuating arm interacts with an output shaft of the drive, the other end of the actuating arm having a slider which is guided in the slide rail.
  • the drive can also be arranged on the frame and the slide rail on the sash.
  • the actuating lever rotates the drive output shaft, thereby tensioning the closing spring in the drive and storing the energy in order to then automatically return the sash to its closed position.
  • the rotary movement of the output shaft is converted into a linear movement which tensions the spring.
  • Toothed pistons can be used here, which interact with a pinion fixed on the output shaft.
  • the rotary movement of the pinion causes a longitudinal displacement of the piston.
  • the piston divides the interior of the drive, which is filled with a hydraulic fluid, into two parts, with the behavior of the drive being adjustable or controllable by means of overflow channels and valves and throttles.
  • the drive In order to use the drive for different opening directions of the sash - DIN left or DIN right - the drive has an output shaft which exits on both sides of the drive, whereby the drive can then also be used for the other direction of rotation when mounted in reverse.
  • drives with a cam disc are often used, which when using a symmetrical cam disc, for example a heart cam, are equally suitable for both directions of rotation of the wing.
  • On the lifting cam are supported by rollers a damping piston acted upon by a return spring and a spring piston acted upon by the closing spring.
  • the damping piston divides the interior of the housing, which is filled with a hydraulic fluid, into two sub-areas. The movement of the damping piston and thus the behavior of the drive can be influenced by overflow channels provided with throttle valves and valves arranged in the damping piston.
  • the drive In order to enable the wing to move freely, a free-wheeling device is arranged on the drive.
  • the drive has a freely rotatable receptacle for the actuating lever on the output shaft. Underneath this receptacle there is arranged a driving disk connected to the output shaft in a rotationally fixed manner, on which an extension is formed.
  • the actuating arm In the area around the receptacle, the actuating arm has a driver which protrudes into the area of movement of the extension on the driver disk.
  • the driver disk which is arranged non-rotatably on the output shaft, is also rotated by the driver.
  • the closing spring is compressed via the toothed piston or the cam disc and the energy is stored in the closing spring, with the hydraulic fluid flowing over from one side of the piston or the damping piston to the other side. If the wing is released, the energy stored in the closing spring causes the piston or the damping piston to be pushed back and the hydraulic fluid to flow back again, which means that the output shaft also rotates back.
  • valve position only enables hydraulic fluid to flow over in the direction required for the opening process and if it is blocked in the opposite direction, the movement of the piston or the cam disc is prevented so that the output shaft cannot turn back.
  • the valve can be operated electromagnetically to prevent the hydraulic fluid from flowing back released or blocked. After releasing the valve, the energy stored in the closing spring rotates the output shaft back, whereby the extension of the drive plate comes into contact with the drive arm of the actuating arm and transfers the rotary movement to it, whereby the wing is guided into its closed position.
  • the driver arranged on the actuating lever which is freely rotatable on the output shaft is guided out of its contact with the extension on the drive plate, and the wing is freely movable despite the locked drive and thus locked output shaft.
  • a freewheel lock is provided.
  • Mechanical fixtures which are used to hold door leaves open, are complex and set to a fixed, usually the maximum possible door opening angle, so that to fix the leaf it must first be opened to the maximum. Furthermore, mechanical hold-open devices are not permitted on fire protection doors; cost-intensive and complex electrical hold-open devices coupled with a fire protection device must be provided here.
  • the freewheel lock is therefore advantageously arranged on the drive plate, which reliably prevents the wing from closing due to the aforementioned low forces on the wing, but triggers it when the force is greater, as occurs by manually closing the wing, and allows the wing to close safely and unhindered. Manual closing of the sash when the drive is locked out of the freewheel lock is thus possible at any time. If the drive lock is triggered, the sash is also safely guided into the closed position by the drive plate.
  • the freewheel lock is particularly advantageously designed in such a way that the freewheel lock is brought about by simply opening the sash when the drive is locked at any desired door opening angle.
  • a drive 3 integrated in a leaf 1 of a door is shown together with an associated frame 2.
  • the slide rail 6, in which the slider 5 is guided, is installed in the frame 2.
  • the slider 5 is rotatably arranged at one end of an actuating arm 4, the other end of the actuating arm 4 being non-rotatably connected to a receptacle 14 of the drive 3 and cooperating with the drive plate 13 of the drive 3.
  • the drive 3 can also be integrated in the frame 2 and the slide rail 4 in the leaf 1.
  • the drive 3 can also be designed in a manner known per se as a drive 3 mounted on the sash 1 or the frame 2.
  • the drive 3 has a housing 7 in which a spring-loaded damping piston 8 and a spring piston 9 are arranged.
  • a closing spring 10 acts on the spring piston 9 as an energy store, which can be pretensioned via a closing force adjustment 15 in order to adapt the drive 3 to different wings 1.
  • the damping piston 8 divides the housing interior filled with the hydraulic fluid into two areas in front of and behind the damping piston 8.
  • the behavior of the drive 3 can be influenced by valves in the piston and by overflow channels in the housing, which are provided with throttle valves. This can be used for the soft opening, soft closing, latching action and a fixing of the wing 1 are executed.
  • the settings can be made manually or electromagnetically or by an electric motor.
  • An output shaft 11 is arranged between the damping piston 8 and the spring piston 9 and is rotatably supported in the housing 7.
  • a cam disk 12 is arranged on the output shaft 11, connected to it in a rotationally fixed manner.
  • the lifting cam disk 12 is symmetrical, for example a heart curve, in order to be able to use the drive both for installation on DIN left and DIN right wings 1.
  • the output shaft 11 has a non-rotatably connected drive plate 13 and a freely rotatable receptacle 14 for the actuating arm 4.
  • a driver 16 can be fixed on the actuating arm 4 and cooperates with the drive plate 13.
  • the drive 3 can also be designed as a drive 3 provided with a toothed piston and pinion and can also be arranged resting on it, the pinion forming the output shaft 11, the shaft ends of which can emerge from the housing 7 on both sides, which also allows use on DIN links as is also possible on DIN right wing 1.
  • the actuating arm 4 can be placed on the receptacle 14 and screwed, wherein the actuating arm 4 can rotate freely without the closer shaft 11 being rotated at the same time.
  • the damping piston 8 and the spring piston 9 each have a rotatably mounted roller 17 at their end facing the output shaft 11, which rollers roll on the cam disc 12 of the output shaft 11. If the output shaft 11 is rotated by opening the wing 1 and the resulting movement of the actuating arm 4 via the driver 16 and the driver disk 13, the damping piston 8 and the spring piston 9 are displaced by the cam disk 12. The rotational movement of the output shaft 11 is converted into a linear movement.
  • the spring piston 9 moves in such a way that the closing spring 10 is tensioned by being compressed and thus stores the energy required for closing the sash.
  • the spring-loaded damping piston 8 is also displaced, whereby the hydraulic fluid can flow from one side of the piston to the other side of the piston through overflow channels.
  • a valve can prevent the hydraulic fluid from flowing back, as a result of which the damping piston 8 can be displaced when the sash 1 is opened, but cannot move back again. This ensures that the cam disc 12 does not rotate back when the sash 1 is closed by the force of the closing spring 10, but further opening of the sash 1 and thus further tensioning of the closing spring 10 and displacement of the damping piston 8 is possible. As a result, the output shaft 11 is blocked with the drive plate 13 fixed on it in the closing direction.
  • a first embodiment of a drive plate 13 is shown, which has an extension 15 on which the driver 16 arranged on the actuating arm 4 can act.
  • the drive plate has a recess 20 for arrangement on the output shaft 11 of the drive 3.
  • a spring tongue 21 is arranged on the drive plate 13, which tongue also cooperates with the driver 16.
  • FIG. 13 is a view from above of a section of the actuating arm 4 placed on the receptacle 14 with the drive plate 13 according to FIG Fig. 3 shown.
  • the drive plate 13 is arranged concealed under the actuating arm 4, but is drawn here with solid lines for better illustration.
  • the housing 7 of the drive 3 is shown in simplified form as a section of a side edge in order to illustrate the respective position of the actuating arm 4.
  • the driver 16 is arranged on the actuating arm 4 in such a way that it extends into the plane of the driver disk 13 and, when the actuating arm 4 rotates, comes into contact with the extension 15 of the driver disk 13, thereby moving it along with it.
  • the drive 3 is in its in the Figure 4a starting position shown. If the wing is 1 in Moving the opening direction of the door, the driver disk 13, which is arranged non-rotatably on the output shaft 11, is rotated by the driver 16 fixed on the actuating arm 4 in the direction of the arrow A, as shown in FIG Figure 4b is shown. As a result, as described above, the closing spring 10 is tensioned.
  • the actuating arm 4 When the valve is closed and the drive plate 13 is blocked in the closing direction, the actuating arm 4 remains in the respective open position as long as no external force acts on the wing 1.
  • the wing 1 is freely movable in the direction of its closed position, decoupled from the drive 3, since the actuating arm 4 is arranged on the freely rotatable receptacle 14 and the driver 16 of the actuating arm 4 can be released from its contact with the extension 15.
  • a free-wheeling lock 19 is provided.
  • the freewheel lock 19 is implemented by the spring tongue 21 which is arranged on the drive plate 13 and cooperates with the driver 16.
  • the driver 16 can be supported on the spring tongue 21, as shown in FIG Figure 4b is shown.
  • the damping piston 8 can move back again and the output shaft 11 with the drive plate 13 rotates back.
  • the spring tongue 21 is overcome by the driver 16 and this comes into contact with the extension of the driver disk 13.
  • the rotary movement of the output shaft 11 is transmitted to the actuating arm 4 and the wing 1 is guided into its closed position. This is particularly advantageous in the case of fire protection doors which have to be closed in the event of danger, the door not always having to be opened against the closing force of the drive 3 in normal operation.
  • the wing 1 of the locked drive 3 can also be easily guided manually out of the freewheel lock 19 by moving the wing 1 in the closing direction, whereby the spring tongue 21 is overcome by the driver 16.
  • the wing 1 can then move freely in the area between the closed position and the holding position, as indicated by the arrow B in Figure 4c is shown.
  • the wing 1 can be guided back into the freewheel lock 19 at any time by opening the wing 1 so far that the driver 16 overcomes the spring tongue 21 in the direction of the extension 15 and is then located between the spring tongue 21 and the extension 15.
  • the locking position of the leaf 1 can particularly advantageously be increased at any time in the opening direction by opening the leaf 1 further. Since the spring tongue of the freewheel lock 19 cooperating with the driver 16 is arranged on the driver 13, the holding position of the wing 1 in the open position always runs with it and is always in the open position selected by the opening movement of the wing 1.
  • the drive disk 13 can be mounted on the output shaft 11 in the opposite direction.
  • the driver 16 on the actuating arm 4 is to be arranged offset accordingly, for which purpose, for example, two threaded bores can be provided in the actuating arm 4, into which the driver 16 can optionally be screwed.
  • FIG. 5 and 6 Another exemplary embodiment is shown, with a drive plate 13, which also has an extension 15 which cooperates with the driver 16. Furthermore, a contour 22 is provided on the circumference of the drive plate 13, which works together with a slide 23 received in a recess in the actuating arm 4.
  • the slide 23 is pretensioned with one or more springs 24 in the direction of the drive plate 13.
  • a package of several springs 24 can advantageously be formed in order to be able to keep the diameter of the springs 24 small and to facilitate installation in the recess in the actuating arm 4.
  • the slide 23 and the spring 24 can be closed on both sides of the actuating arm 4 with a cover 25 each, which are screwed to the actuating arm 4, for example.
  • the function and mode of operation of the arrangement corresponds in principle to that of the first exemplary embodiment, but the freewheel lock 19 is formed by means of the contour 22 and the spring-loaded slide 23.
  • the wing 1 of the door is prevented from closing by the contour 22 and the spring-loaded slide 23, which rests against the contour 22, as shown in FIG Fig. 6 is shown.
  • the wing 1 is freewheeling by a movement in the closing direction, since the slide 23 slides on the contour 22 and moves along the increased freewheeling area 27 of the drive plate 13 with a further movement of the wing 1.
  • a roller 26 can be provided, which facilitates the sliding of the slide 23 on the contour 22 of the drive plate 13 and further reduces the inherently low forces due to the sliding of the slide 23 in the free-running area 27 of the drive plate 13 reduced.
  • a section of an actuating arm 4 of a further embodiment of the spring-loaded slide 23 is shown.
  • the spring 24 is formed from two leg springs which are designed to converge at their ends. If the slide 23 runs up against the contour 22 of the drive plate 13, not shown here, the two legs of the spring 24 are spread apart by a spreading element 28, whereby the force is exerted on the slide 23 in the direction of the drive plate 13. This advantageously results in a very small overall size, which simplifies integration into the recess in the actuating arm 4.
  • Possible threaded bores 29 for an alternative arrangement of the driver 16 are also shown by way of example.
  • the spring 24 and a one-armed or two-armed lever 31 pivotably mounted in a pivot bearing 30 are arranged in a receptacle 32 within the drive plate 13.
  • the drive disk 13 can be closed by a cover which is identical in its external shape and is not shown here, as a result of which the spring 24 and the lever 31 are arranged securely in the receptacle 32.
  • a two-armed lever 31 is provided, which is mounted in the pivot bearing 30.
  • a first lever arm 31a engages behind the screw head of an adjusting screw 33, which is received in a threaded sleeve 34, the threaded sleeve 34 being fixed in the drive disk 13, for example by being pressed into place.
  • the position of the lever arm 31a can be adjusted with the adjusting screw 33, as a result of which the freewheel lock 19 can be adjusted with regard to the holding force.
  • the second lever arm 31b of the lever arm 31 protrudes into the possible path of movement of the driver 16, the lever 31 here being made of spring steel, whereby at least the lever arm 31b forms the spring 24 and thus an adjustable spring tongue 21, as shown in the embodiment according to Fig. 3 is to describe, represents.
  • the two-armed lever 31 is rigid, with a spring 24 wound in sections tapered at the ends being provided on the first lever arm 31a, the ends of which are only inserted into one of the openings provided on the lever arm 31a and at the other end into an adjusting screw 33.
  • the spring 24 With the adjusting screw 33, the spring 24 can be adjusted with respect to the lever arm 31a, whereby the freewheel lock 19 can be adjusted with respect to the holding force.
  • the second lever arm 31b of the lever arm 31 protrudes into the possible path of movement of the driver 16, which is in the Figures 8 to 10 is just in contact with the extension 15 and is so between the extension 15 and the lever arm 31b.
  • the leaf 1 is in the partially open position when it is locked Drive 3, the wing 1 can be brought out of the freewheel lock 19 into the freewheeling area 27 by pulling the lever arm 31b protruding into the path of the driver 16 through the driver 16 against the spring 24 or against the spring force of the lever arm 31b itself, in the Drive plate 13 is pivoted into it. This is promoted by the shape of the end of the lever arm 31b, which is advantageously rounded at the end.
  • the force required to guide the wing 1 into the free-wheeling area 27 is determined by the effective length of the lever arms 31a, 31b and the spring force of the spring 24, the adjustability of the spring 24 coordinating the free-wheel lock 19 with the wing 1 allowed on its size and weight.
  • the free-running wing 1 can be guided back into the free-wheel lock 19, the driver 16 overcoming the lever arm 31b again in the opposite direction and reaching the area between the lever arm 31b and the extension 15 of the driver disk 13.
  • a one-armed lever 31 mounted in the pivot bearing 30 is provided, which is supported on a spring 24 designed as a compression spring.
  • the lever 31 has a cam 35 on one side, which is directed outwards and protrudes into the path of movement of the driver 16.
  • the freewheel lock 19 functions as described above, the driver 16 having to overcome the cam 35, which is displaced by the driver 16 out of the movement path of the driver 16 in the direction of the driver disk 13.
  • an adjusting screw 33 which, for example, is arranged opposite the lever 31 at the end of the spring 24 within the drive plate 13.
  • Fig. 11 Another embodiment of a freewheel lock 19 is shown, only a partial section in the area of the drive plate 13 is shown.
  • the freewheel lock 19 is implemented with a tappet 36 acted upon by the spring 24, which is arranged in the area around the output shaft 11 in the drive 3 parallel to the axis of the output shaft 11.
  • the spring-loaded tappet 36 interacts with the driver 16, the driver 16 being supported on the tappet 36 in order to hold the wing 1 in the freewheel lock 19. If the wing 1 is in the Freewheel area 27 guided, the plunger 36 is pushed back against the spring 24 by the driver 16.
  • the end of the plunger 36 and the driver 16 are rounded at least at the edges in order to facilitate sliding on.
  • the illustrated embodiment shows a freewheel lock 19, also in a partially cut section, the drive disk 13 having a roller 37 on the circumference, which cooperates with the driver 16.
  • the drive plate 13 can be displaced axially on that of the output shaft 11, the drive plate 13 being supported against the actuating arm 4 by means of the spring 24 formed from cup springs. If the wing 1 is guided out of the freewheel lock 19, the driver 16 runs onto the roller 37, whereby the actuating arm is raised according to arrow C and the driver 16 overcomes the roller 37 and enters the freewheel area 27 of the driver disk 13.
  • the driver 16 is advantageously rounded at the edges.
