Definitions

  • the invention relates to a door closer, consisting of a piston arrangement guided in a housing and mechanically coupled with a rotatably mounted closer axis, at least one closing spring interacting with the piston arrangement and a hydraulic damping device.
  • This known closer is designed such that the torque acting on the closer axis has its maximum in the zero position, decreases rapidly in the area of the small opening angle, then remains approximately the same and finally gradually drops to zero at an opening angle of 180 °.
  • the closing spring is guided on a hollow cylinder arranged in the closer housing and in slits at the ends of the same one slider serving as an abutment is displaceable in such a way that the slider facing the closer axis by means of a roller on one of the The cam is seated on the closer axis and the other slider is connected by a link to a crank which is mounted in the end of the housing opposite the closer axis and is non-positively connected to the closer axis by a chain drive.
  • this known device is extremely complex and, on the other hand, it offers only limited possibilities with regard to the specification of a specific closing force curve.
  • the gear ratio of the respective NO contact i.e.
  • great attention must be paid to the instantaneous ratio of the rotational angular velocity of the closer axis to the rotational angular velocity of the door, particularly when special demands are made of closers, be they overhead door closers or floor door closers.
  • This is the case, for example, with so-called slide arm closers, in which the closing torques are unfavorable because, with a small opening angle, when the door has to be pressed into the lock, only a comparatively small moment is available.
  • sliding arm closers which are characterized by an optically favorable appearance, the friction ratio at the moment the wing is opened is favorable, since there is little friction with a small opening angle, relatively long guide rails must always be accepted in order to ensure the required functional reliability.
  • the object of the invention is to provide a door closer which can be used both as an overhead door closer and as a floor door closer and in particular as a sliding arm closer, which fulfills both the requirements for compact design and economical manufacturing possibilities and the requirement for functionally optimal closing moments and accordingly the use of short, in sliding arm closers the dimensions of the closer dimensions of corresponding guide rails allowed.
  • this object is essentially achieved in that the piston arrangement consists of two pistons which can be displaced coaxially one inside the other and in relation to one another, and that these two pistons are coupled to the closer axis by means of separate gear elements having different transmission functions.
  • the effective total closing torque can be varied within a wide range, depending on the opening angle, by means of pistons which can be acted upon in a predefined manner and with different ratios against the respective spring force, since the total closing torque results from the addition of the individual closing torques assigned to the two pistons and thus, for example, a proportionally increasing closing torque can be combined with a closing torque that is high at small opening angles and then decreases in a predeterminable manner, so that, for example in the area of small opening angles, a correspondingly high total closing torque can be selected and this total closing torque can then be reduced to a lower, but essentially constant closing torque over the entire opening angle.
  • a combination of the closing torques originating from the two pistons can produce a total closing torque that also provides a fully satisfactory closing force curve when the closer axis is arranged relatively close to the door pivot bearing, surprisingly short guide rails can be produced use, which results in a particularly favorable optical appearance.
  • the two pistons are each supported via a compression spring on a housing-fixed, in particular adjustable stop. Even if the preload of the two springs is changed by the adjustable stop, the overall characteristic predetermined by the gear elements is retained.
  • the closer axis is arranged in a corner region of the housing and is coupled to the gear elements having different translation functions via an axially fixed gearwheel.
  • This arrangement enables an extremely low k-value, the small transverse dimension being of particular importance.
  • the gearwheel assigned to the closer axis can be moved directly to the edge of the housing, and it is also possible to choose different gearwheels in order to vary the course of the force achieved.
  • the side k dimension in floor door closers for single-action doors can be 20 mm.
  • a variant of the invention which is characterized by particular simplicity and operational reliability, for solving the problem, has at least one eccentric pinion for engaging the closer axis and piston, which engages in a complementary toothing which is at least non-positively assigned to the piston.
  • the pitch curve of the pinion connected to the closer axis continuously changes from an area with a minimal radius to an area with maximum radius, while the toothing on the piston side associated with the pinion runs in accordance with an elongated and flat S-shaped pitch curve.
  • a feature of the invention which is characterized by particular compactness, low manufacturing costs and high operational safety is characterized in that the piston-side toothing is formed on a rack-shaped extension of the piston and this extension forms a wall section of the piston designed as a hollow piston, the eccentric pinion in the piston cavity is located.
  • the closer axis is arranged in a corner region of the housing and is coupled to the toothing assigned to the piston via two eccentric pinions. In this way, very high gear ratios can be achieved with an extremely compact design without sacrificing functionality and operational reliability or service life.
  • the closer axis is coupled via an eccentric pinion with a center-symmetrically designed toothed segment which is pivotally mounted and is articulated on the piston via a connecting element which is in relation to one of the closed positions corresponding center position is under spring tension on both sides.
  • the The closer axis is preferably arranged in a corner area of the housing and connected to an eccentric pinion, which is connected to the piston via an eccentric tooth segment, the pivot axis of which is preferably located in the housing half opposite the closer axis, and via a connecting element articulated on this tooth segment Spring biased against a first fixed stop and is movable up to a second fixed stop.
  • a double-piston arrangement is provided in a closer housing 1, which is formed by an outer piston 5 designed as an annular piston and an inner piston 8 which is coaxial with it and passes through the annular piston and is guided by the annular piston.
  • a first compression spring 9 is assigned to the outer piston 5 and a second compression spring 10 is assigned to the inner piston 8. Both springs are preferably supported on a common, in particular adjustable stop 16.
  • the outer bulb 5 is sealed with respect to the housing wall by means of a seal 14, while a seal 13 is provided between the outer bulb and the inner bulb 8.
  • a plastic sleeve 12 held in the outer bulb 5 serves to protect the sliding surfaces.
  • the outer bulb 5 has at least one shoulder which extends in the direction of the housing end opposite the fixed stop for the springs 9, 10 and which is designed as a toothed rack 4.
  • This rack 4 meshes with a gear 3, which is rotatably connected to the closer axis 2.
  • the resulting lever arm between rack 4 and closer axis 2 is designated by the letter a.
  • the control member 6 has the shape of a cam disk, the course of the cam outer surface, which cooperates with the fixed stop 7, can be selected in accordance with the respectively required closing torque course.
  • the closer is in a position corresponding to a closed wing, and the fixed stop 7 lies against a contact surface 11 of the control element 6, in which a lever arm b results with respect to the closer axis 2.
  • This lever arm b can be larger than the lever arm a between gear 3 and rack 4.
  • both the outer piston 5 and the inner piston 8 are displaced against the respective force of the biasing spring 9, 10.
  • the restoring axis 2 acts as the restoring torque, the sum of the individual torques which are exerted by the two pistons 5, 8 via their transmission transmission elements 3, 4 and 6, 7.
  • a second closing torque can be generated via the cam-shaped control member 6 by the inner piston 8, which is large at small opening angles and then decreases in the course of increasing opening angles, and possibly drops so much that, at large opening angles, it is even opposite to the closing moment resulting from the outer bulb.
  • the outer piston is provided with spaced double toothed racks 4 and the control member 6 and the fixed stop 7 are located between these two toothed racks and the inner piston 8 via a support guide shoulder 22 on a corresponding one Sliding surface of the racks is guided. In this way, the occurring forces are optimally absorbed and wear and tear is minimized.
  • FIG. 2 The embodiment variant of the invention shown in FIG. 2 is intended for hinged doors in the same way as the embodiment according to FIG. 1, but is specifically designed as a floor door closer.
  • the control member 6 has a modified outer contour that can generate a negative closing torque due to the reduction in the radius and thus the lever arm in the area assigned to the large opening angles.
  • the total torque, originating from the outer piston and inner piston, is still positive, but it is avoided by the contribution of the inner piston with a large opening angle that the compression spring 9 assigned to the outer piston 5 causes a further, no longer required increase in the closing torque.
  • k-dimension which should be as small as possible, is of particular importance for floor door closers.
  • FIG. 3 A further embodiment of the invention is shown in FIG. 3, the same reference numerals as in FIGS. 1 and 2 also being used in this figure for the same elements.
  • a special control element 6 which is no longer designed as a pure cam disc, but consists of a disc element toothed on a partial area of its circumference, which engages in a toothed rack attachment 17 of the inner piston 8 by means of a tooth section in the area of small opening angles and comes out of engagement from a predeterminable opening angle.
  • the inner piston 8 is connected via a rigid or flexible connecting element 21 to an eccentric element 20 which is attached to the gear 3.
  • the connecting element 21 is articulated on the outer region of the eccentric 20. This articulation is carried out in such a way that when the closer axis moves counterclockwise and the wing is opened, the inner piston 8 is moved in the direction of the closer axis and thus in the opposite direction to the outer piston 5.
  • a compression spring 19 is provided, which takes over the function of the previously described two compression springs 9, 10 in this embodiment.
  • Fig. 5 shows a schematic of a pinion 25 to be connected to a closer shaft, which meshes with a piston-fixed toothing 27.
  • the pinion 25 has a pitch curve 26, which is composed of a first circular section with the radius R1, an adjoining circular section with the radius R2 and an in turn continuously adjoining circular section with the radius R3.
  • the middle pitch curve section with the radius R2 has the least curvature, ie the radius R2 is much larger than the radii R1 and R3.
  • the pitch curve section with the smallest radius R3 is in the shown schematic representation in engagement with the toothing 27, the position shown corresponds to the opening angle zero of the closer, i.e. the associated door is closed. If the door is opened, the spring force acting on the piston and thus on the toothed rack carrying the toothing 27 is effective via the lever arm A, i.e. a high closing force is available in the area of small opening angles.
  • the lever arm decreases in accordance with the selected course of the rolling curves, down to the value B, which corresponds to the radius R 1 of the rolling curve 26 of the pinion.
  • the ratio of A to B is 2: 1. This ratio corresponds to the translation achieved.
  • the maximum pressure angle in an embodiment according to FIG. 5 is identified by ⁇ .
  • FIG. 6 shows an arrangement particularly suitable for floor door closers.
  • an eccentric pinion 30 is connected to the closer axis, which meshes with a further, rotatably mounted, eccentric pinion 25, which in turn is in engagement with a toothing 27 which is fixedly connected to the piston, in particular in the form of a rack.
  • the pitch curve 31 of the eccentric pinion 30 extends with respect to the axis of rotation such that the lever arms effective with respect to the pinion 25 change from the maximum value A3 to the minimum value B3 over the full opening angle of the closer.
  • the rolling curve 31 of the pinion 30 is assigned a rolling curve 29 on the pinion 25, which is indicated by dashed lines and extends approximately over half the circumference of the pinion 25.
  • the other half of the circumference of the pinion 25 has a rolling curve 26 which interacts with the toothing 27 and which, in turn, is associated with the very flat rolling curve 28 of the toothing 27.
  • the minimum effective radius of the pinion 25 is marked with B2 and the maximum effective radius with A2.
  • a particularly favorable k-dimension of, for example, 20 mm results, it being essential for the floor closer that, despite the very flat rolling curve 28 of the toothing 27, a very high transmission ratio can be achieved.
  • the translation ratio is determined from the product of the individual translations, ie in the present case from the product ⁇ ⁇ .
  • a ratio of, for example, 4.5 to 1 can be achieved without problems in practice.
  • Fig. 4 shows a partial sectional view of an overhead door closer designed according to the invention.
  • a piston 33 is arranged in the housing 1 and is biased in the usual way into the closed position by means of compression springs 34.
  • the piston 33 In its area facing away from the springs 34, the piston 33 has a recess or a cavity 32 in which an eccentric pinion 25, which is connected in a rotationally fixed manner to the closer shaft, is arranged.
  • This pinion 25 is in engagement with a toothing 27 which is matched with regard to its rolling curve to the corresponding rolling curve of the pinion 25.
  • a check valve 43 belonging to the damping device is provided in the area of the piston recess 32 on the spring side.
  • Fig. 8 shows an embodiment of the invention in the form of a floor door closer for swing doors.
  • the eccentric pinion 25 is arranged in a corner region of the housing 1 in order to achieve the most compact possible construction and is in engagement with a center-symmetrical tooth segment 35.
  • This tooth segment 35 is articulated in the center and is connected to the piston 33 via a lever 36.
  • the lever 36 is hinged at both ends.
  • the piston 33 is provided with a rod 38 which carries an axially adjustable support and guide disk 39 in the region of its end. Between this support and guide plate 39 and a stop sleeve 37 directly adjacent to the piston 33 in the middle position, a compression spring 34 is arranged, which is acted upon depending on the direction of the pivoting movement of the associated swing door, on the one hand via the support and guide plate 39 when supported on the stop sleeve 37 and on the other hand by the stop sleeve 37 when supported on the support and guide sleeve 39 which is fastened to an adjustable sleeve 40 which on the one hand slidably receives the piston rod 38 and on the other hand from the outside of the housing in the axial direction can be adjusted.
  • the course of the closing force can in turn be predefined optimally.
  • Fig. 9 shows an embodiment of the invention in the form of a floor door closer for hinged doors.
  • the eccentric pinion 35 is in turn preferably arranged in a corner region of the housing and interacts with an eccentric segment 41 which is pivotally mounted and via a connecting rod 36 is coupled to the piston 33.
  • the cup-shaped piston 33 is biased by a spring 34 against the bottom of the housing 1 and movable between this bottom and a housing stop 42.
  • the eccentricities or rolling curves of the pinion 25 and toothed segment 21 can in turn be selected in accordance with the desired closing force profile.
