- the bearing bush is rotatably connected to the bearing base.
- It also has a locking device which has a spring-loaded locking means in the form of a locking ring for the storage and determination of the handle neck. The latter is manually movable against a compression spring in the direction of the bearing base, wherein the compression spring is also designed as a torsion spring to bring the door handle back to its horizontal position after releasing.
- a non-rotatably mounted on the handle neck drive plate is provided, which must be performed during assembly of the fitting with an angled driver pin between the unwound spring ends of the compression and torsion spring.
- This is not only very expensive, it also requires a certain amount of skill to bring the drive pin in the assembly of the handle neck exactly between the spring ends can.
- this structure is extremely complex and therefore expensive to manufacture. A pre-assembly of the return spring means is not possible. The operating angle of the handle is limited.
- a handle set for actuating a lock nut provided with a square socket.
- This has a fixable on a door or a window bearing part in the form of a rosette or a shield, a handle with a bearing neck mounted in the neck with a square socket for receiving a square pin, and a restoring device for returning the handle in a non-actuated position.

- the invention provides that the central recess of the housing is provided at the edge with a step
- the driving element of the return spring device is rotated in the housing over the square pin.
- the driver pin deflects on the driver element of one of the spring ends, which can move within the respective associated recess in the circumferential direction, while the other end of the spring element is supported on the stationary stop element in the housing. If you let go of the handle, this returns due to the force acting on the driver spring or restoring force back to its original position.
- the recesses can be dimensioned almost arbitrarily due to the simple geometry, so that with the device according to the invention in comparison to conventional constructions even larger operating angle can be realized easily.
- driver element in the housing you can perform the handle movement in the other direction, so that the return spring means are easily used for both right and left hand grips can; it is universally usable.
- the return spring device is thereby formed by the housing, the driver element and the spring element - thus only a few components. It therefore has a very simple and clear structure with a simple geometry that is rational and therefore inexpensive to produce. All components can also be quickly and easily assembled into a unit, which ensures easy installation.
- the driver element is always smoothly and reliably stored without complex bearing elements are necessary.
- the central recess in the housing shell is substantially circular, so that it forms a bearing for both the driver element and, if necessary, for the handle of the fitting.
- the recesses adjacent to the recess are preferably arcuate and coaxial with the recess, so that the spring ends engaging therein over the entire Operating angle away can move freely. This is limited in the circumferential direction only by the abutment surfaces for the driver element and / or for the spring ends of the spring element, ie by appropriate choice of the arc length of the recesses can be realized in a simple manner different operating angle. Design changes or even additional components are not required.
- the preferably integrally formed with the housing shell stop element forms - as well as the arcuate recesses - a bow or ring section. It is limited in the circumferential direction of the stop surfaces of the recesses, so that the protruding into the recesses ends of the spring element can be supported in both directions of actuation of the stop element.
- the Mitauersteg the driver element forms a bow or ring portion, wherein the center angle of the stop element in the housing and the center angle of the Mitiliastegs on the driver element are preferably the same size.
- the entrainment element is in its home or rest position, the Mitauersteg is preferably immediately adjacent to the stop element of the housing shell. Both together form a symmetrical circular sector with substantially straight side surfaces.
- the spring ends of the spring element can always support reliable.
- the latter can be operated via the handle, the square pin and the driving element at any time in both directions by the Mit videsteg each entrains a spring end, while the other end of the spring remains on the stationary stop element.
- the spring element is stretched and leads - after releasing the handle - the driver element and with this the handle back to its original position.
- the handle of the fitting is thus always reliably brought back into its mostly horizontal starting position, regardless of the state of a possibly existing lock spring.
- the driver element For storage and guidance of the spring element, the driver element has a neck portion, wherein the driver web and the neck portion are radially spaced, so that the spring element can be arranged therebetween.
- the housing has a substantially cylindrical outer surface. This can - depending on the installation situation - at least partially flattened laterally, for example, to accommodate the return spring in a narrow door plate can.
- a further embodiment of the invention provides that the outer surface of the housing carries or forms radially protruding latching projections in order to be able to define, for example, a separate shield or rosette cover.
- the housing is or forms a stop element for the fitting. It can then be fixed to a stop surface for fitting, with screw holes being formed in the housing for this purpose.
- the invention further provides that the central recess of the housing forms a bearing opening for the handle of the fitting. It may be advantageous if the bearing opening is limited by a neck portion.
- the handle, in particular the handle neck, thus finds an always safe and wobble-free guidance.
- the cover is non-positively and / or positively with the Housing shell connectable, in particular clamped and / or latched. Through the cover both the driver element and the spring element are secured in the housing, unless the driver element is fixed axially in the housing shell. In this case, the cover would be unnecessary.
- the cover has a central recess which rotatably receives the driver.
- the latter can be provided for this purpose with an additional edge or a projection which engages rotatably in the recess.
- the driver element is thereby additionally or alternatively rotatably mounted in the housing. In order to ensure a low overall height, close the cover and the driver element flush with each other.
- the spring element is preferably a torsion spring or a spiral spring, which lays with one or more turns around the neck portion of the driver element.
- the spring ends of the spring element extend radially to the axis of rotation of the driver element, so that they can always reliably abut the stop element of the housing and the driver pin of the driver element.
- the spring element has a depth in the axial direction, which is preferably smaller than the axial depth of the central recess in the housing shell.
- the depth of the spring element is determined essentially by the thickness of the spring element material used and the number of windings or windings. Measured in the axial direction, however, the depth of the spring element is always smaller than that provided for receiving the spring element depth of the recess, so that both the spring element and the driver element do not protrude beyond the end face of the housing shell.
- the depth of the Mit supportivestegs of the driver element in the axial direction is dimensioned so that it corresponds approximately to the depth of the spring element. That is to say the carrier web has a depth with which it always reliably detects both ends of the spring element.
- the spring is mounted biased, ie the spring ends cross each other and are characterized by bias on the stop element and the driving pin on. To adapt to different handle weights you can bring the spring element but also without bias. Constructive changes are not necessary.
- the housing, the driver element and the spring element form a preassembled unit. These can be due to their simple geometry not only cost-effective manufacture, but also easily add automated.
- the housing, the driver element and the spring element are also all symmetrical, so that the return spring unit is not only used on both sides, but can also be installed in any position. Mounting and operating errors are thereby reliably avoided.
- a door fitting for which independent protection is claimed is provided with a return spring device according to the invention, wherein at least one handle is rotatably or pivotably mounted on or in a stop element.
- the return spring device receives in its driving element on the square pin of the fitting, so that upon actuation of the handle, the driver element is rotated.
- the spring element in the housing of the return spring device is tensioned. If you let go of the handle, the driver element and the coupled handle - regardless of the state of a lock spring - always reliably moved by the spring element back to the starting position.
- a guide ring is provided between this and the stop element. This serves as a plain bearing. He is preferably rotatably connected to the stop element.
- a further development provides that the guide ring with the housing of the return spring means is non-positively and / or positively connected. The latter is thus fastened to the stop element and at the same time held against rotation, which is particularly advantageous if the stop element is a door plate. It is expedient if the housing of the return spring device can be inserted into the door plate.
- the return spring means is completely covered by the shield and is not visible to the outside, which has a favorable effect on the appearance of the fitting.
- the guide ring is integral with the housing of the return spring means. This is advantageous in particular when the stop element is a rosette and when the stop element is formed by the housing of the return spring device. This results in a particularly compact design.
- a cover can be fixed, which is preferably latched to the radially issued locking projections on the housing.
- the in Fig. 1 generally designated 70 fitting is designed as a door fitting. He has a handle 72 which is rotatably mounted with a handle neck 71 in a stop member 74.
- the latter for example, has the form of a narrow door plate which is fixed by means of screws (not shown) to a door leaf (also not shown). To accommodate the screws 74 holes 73 are provided in the door plate.
- a guide ring 75 with a bearing opening 25 for the handle neck 71.
- the ring 75 is inserted in a circular recess 76 in the door plate 74 and fixed by means of circumferentially arranged locking springs 85 therein. He also carries circumferentially radially flared projections 77 which engage in anti-rotation in corresponding recesses 79 in the edge of the recess 76.
- a square pin 80 is rotatably inserted, which is axially secured by a grub screw 82.
- the square pin 80 engages through a back in the door plate 74 used remindholfeder disturbed 10 in a (not shown) Sch primanuß a lock in the door leaf.
- the return spring means 10 is provided to bring the handle 72 always reliable after its operation in its horizontal starting position. It is designed as a preassembled unit and is composed of a housing 20, a driver element 40 and a spring element 50.
- the housing 20 has a housing shell 21 and a rear-mounted cover member 27 in the form of a lid, which has substantially the same outer contour as the housing shell 21 and is provided with pins 39.
- the latter engage non-positively and / or frictionally engaged in corresponding holes or recesses 59 in the housing shell 21, so that a fast-to-install and permanently secure connection is ensured.
- a central circular recess 22 is formed for rotatably receiving the driver element 40 and the spring element 50.
- two arcuate recesses 30, 34 are introduced in the housing shell 21, which are bounded in the circumferential direction U respectively by end surfaces 31, 32 and 35, 36.
- a stop element 26 is formed for the spring element 50, which also forms a bow or ring section. It can be seen that the recesses 30, 34 coaxial with the recess 22 and symmetrical to the stop element 26, wherein the end surface 31 of the recess 30 and the end surface 35 of the recess 34 at the same time form the boundary surfaces of the stop element 26 (see also Fig. 5 ).
- the arc length of the recesses 30, 34 is selected so that the angular distance between the end surfaces 31, 32 and 35, 36, for example, 60 °, which is readily possible due to the simple geometry of the housing shell 21.
- the recess 22 in the housing 20 forms an opening 58 which corresponds in diameter to the recess 79 in the door plate 74. If the return spring device 10 is inserted back into the door plate 74, the guide ring 75 engages positively and / or positively with its detent springs 85 into the opening 58 and thus into the housing 20, so that the return spring device 10 is firmly connected to the door plate 74 , Recesses 57 introduced on the edge side in the opening 58 receive the radially protruded projections 77 of the guide ring 75, so that the housing 20 is also secured against rotation in the door plate 74.
- the housing 20 has a substantially cylindrical outer surface 28. However, this is in the embodiment of Fig. 1 and 2 Flattened laterally, so that the return spring means 10 - as shown - can also be used in narrower door plates 74 and is always completely covered by these.
- the lateral flattening of the housing 20 also serves as rotation in the door plate 74.
- at least two fferbohronne 23 are introduced in the housing 20 at the edge, both the housing shell 21 and the cover 27th push through.
- Carrier element 40 shown in detail is rotatably supported in the recess 20 in the housing 20 against the restoring force of the spring element 50. It has a substantially circular disc basic shape and centric to the rotation axis A a square recess 42, which serves for the rotationally fixed coupling with the square spindle 80. Laterally projecting in the radial direction, the drive plate 40 has two diametrically opposite tabs 43, which are supported in a sliding manner in the axial direction on the housing shell 21. Its recess 22 is provided on the edge side with a substantially annular step 24, on which the tabs 43 slidably rest. The latter are in the axial direction offset from an edge step 45.
- the driver element 40 is rotatably seated in a central recess 37 in the cover 27. This thus forms a pivot bearing for the driver element 40, via the between the annular step 24 and the cover 27 slidably guided tabs 43 is axially secured. In order to ensure a low overall height, close the cover member 27 and the driver element 40 flush with each other.
- This web 44 forms - as well as the stop element 26 and the adjacent recesses 30, 34 in the housing 20 - a bow or ring portion whose center angle ⁇ the center angle ⁇ of the Stop element 26 corresponds (see Fig. 5 and 6 ).
- the stop element 26 and the entraining web 44 thus form mutually adjacent an annular circular sector, wherein the Mitauersteg 44, the side surfaces 31, 35 of the stop member 26 and the recesses 30, 34 continues radially to the axis of rotation A.
- the driver element 40 Coaxially to the axis of rotation A, the driver element 40 has a neck portion 46, wherein the driving web 44 and the neck portion 46 for receiving the spring element 50 are radially spaced.
- the spring element 50 is preferably a torsion spring or a spiral spring that lies around the neck section 46 of the driver element 40 with one or more windings. It also has two radially to the axis of rotation A angled spring ends 52, 53 which lie on both sides of the Mitauerstegs 44 and engage on both sides of the stop element 26 in each case a recess 30, 34 of the housing shell 21.
- the spring ends 52, 53 thus close the annular sector formed by the stop element 26 and the Mitauersteg 44, wherein the side surfaces 31, 35 of the stop element 26 and the recesses 30, 34 serve as abutment surfaces for the spring ends 52, 53.
- the cam member 40 rotates in one direction, e.g. to the right, the end 52 of the spring 50 is deflected by the Mitauersteg 44 in the circumferential direction U to the right, while the other end 53 is supported on the stop surface 31 in the recess 30 and the stop element 26.
- the spring 50 is tensioned. If you let go of the handle 72, the spring 50 rotates the driver element 40 via the Mitauersteg 44 back to its original position in front of the stop element 26. The handle 72 is moved back over the square pin 80 in its horizontal position.
- the spring end 52 moves in the arcuate recess 34 until it abuts against the second boundary surface 36. This therefore forms a stop both for the rotational movement of the driver element 40 and for the pivoting movement of the handle 72. Due to the relatively large arc length of the recess 34 and the angular distance of 60 ° between the abutment surfaces 35 and 36, the handle 72 - conventional fittings with return spring means - perform a relatively large pivoting movement.
- the return spring device 10 can therefore be used universally both for a right as for a left-hand operation, without the need for another component or that it requires design changes.
- the pivoting angle of the driver element 40 within the housing 20 can also be adjusted to e.g. Limit 40 ° by the arc length of the recesses 30, 34 is chosen correspondingly smaller.
- Another alternative provides that not the spring ends 52, 53 on the boundary surfaces 32, 36 of the recesses 30, 34 come to rest, but for example, the tabs 43 of the driver 40. Also by the pivoting movement can be limited, so that for example the spring element 50th not overloaded.
- Fig. 3 shows its another embodiment of a fitting 70 according to the invention with an alternative design of a remindholfederelements invention 10.
- Its housing 20 forms here directly the stop element 74 in the form of a rosette which is fastened by means guided in holes 23 (not shown) screws on the door leaf.
- 23 cams 33 are formed in the region of the bores, which engage in corresponding holes (not shown) in the door leaf.
- the handle 72 of the fitting 70 is rotatably mounted with its handle neck 71 in the stop element 74 and thus in the housing 20 of the return spring means 10.
- the central recess 22 of the housing 20 forms the bearing opening 25 for the handle neck 71, which is preferably bounded by a neck portion 38 (see Fig. 4 ). It can be seen that the neck portion 38 forms the guide ring 75, which is thus integral with the housing 20 of the return spring means 10. An anti-rotation is therefore not necessary here.
- a cover 78 is provided, which is placed on the housing shell 21.
- the substantially cylindrical outer surface 28 of the housing 20 bears radially protruding latching projections 29 which can be latched to the inner circumference of the cover 78 (not described in more detail).
- the housing shell 21 is provided with curved oblong holes 49 in the region of the latching projections 29, so that the latching projections 29 are seated on spring webs 89 and can radially spring inwardly when the cover 78 is placed on the housing 20.
- the cover 78 has a central opening 88 which receives the neck portion 38 of the housing shell 21.

Die Erfindung betrifft eine Rückholfedereinrichtung für Tür- oder Fensterbeschläge gemäß dem Oberbegriff von Anspruch 1 und einen Tür- oder Fensterbeschlag gemäß Anspruch 26.The invention relates to a return spring device for door or window fittings according to the preamble of claim 1 and a door or window fitting according to
Türschlösser besitzen gewöhnlich eine federbelastete Falle, die über Türgriffe betätigbar ist. Letztere sind meist als Bestandteile eines Beschlags zu beiden Seiten eines Türblatts in einem Anschlagkörper drehbar gelagert und über einen Vierkantstift axial- und drehfest miteinander verbunden. Der Vierkantstift durchsetzt formschlüssig eine Schlossnuss, die innerhalb des Türschlosses von einer Schlossfeder in einer Ausgangsstellung gehalten wird. Nach Betätigung des Türgriffs wird die Falle zurückgezogen und nach Loslassen des Griffs wieder in ihre Ausgangsstellung zurückgebracht. Das gleiche gilt für die Schlossnuss und den damit verbundenen Griff. Ist zumindest einer dieser Griffe gemäß einer Knopfform ausgebildet, so reicht die Kraft der Schlossfeder meist aus, um die Rückkehr des Türgriffes in seine Ausgangsstellung zu bewirken. Abgewinkelte Griffe oder Hebel, die nicht selten aus spezifisch schwerem Material wie Messing oder Stahl bestehen, werden jedoch oft aufgrund ihres Eigengewichts nicht immer vollständig in die Ruheposition oder die Ausgangsstellung angehoben und in dieser Position gehalten, insbesondere dann, wenn die Schlossfeder nach längerem Gebrauch bereits ermüdet oder zu schwach dimensioniert worden ist.Door locks usually have a spring loaded latch which is operable via door handles. The latter are usually rotatably mounted as components of a fitting on both sides of a door leaf in a stop body and connected via a square pin axially and rotationally fixed to each other. The square pin penetrates positively a lock nut, which is held within the door lock by a lock spring in a starting position. After pressing the door handle, the case is withdrawn and returned to its original position after releasing the handle. The same applies to the lock nut and the associated handle. If at least one of these handles is designed according to a button shape, then the force of the lock spring is usually sufficient to bring about the return of the door handle to its initial position. Angled handles or levers, which are often made of specific heavy material such as brass or steel, however, are often not fully raised due to their own weight in the rest position or the starting position and held in this position, especially if the lock spring after prolonged use already fatigued or too weakly dimensioned.

Hauptmerkmale der Erfindung sind im kennzeichnenden Teil von Anspruch 1 und Anspruch 26 angegeben. Ausgestaltungen sind Gegenstand der Ansprüche 2 bis 25 und 27 bis 37.Main features of the invention are set forth in the characterizing part of claim 1 and claim 26. Embodiments are the subject of claims 2 to 25 and 27 to 37.
Bei einer Rückholfedereinrichtung für Tür- oder Fensterbeschläge, mit einem in einem Gehäuse gegen eine Rückstellkraft drehbar gelagerten Mitnehmerelement, das zentrisch zu einer Drehachse eine Vierkantausnehmung zur Aufnahme eines Vierkantstifts aufweist, der drehfest mit wenigstens einem dreh- oder schwenkbar gelagerten Griff des Beschlags verbindbar ist, wobei die Rückstellkraft von einem Federelement erzeugt wird, wobei das Gehäuse eine Gehäuseschale aufweist, die zur Aufnahme des Mitnehmerelements und des Federelements mit einer zentralen Ausnehmung versehen ist, wobei die Gehäuseschale radial angrenzend an die Ausnehmung zwei Aussparungen aufweist, zwischen denen ein Anschlagelement für das Federelement ausgebildet ist, wobei das Mitnehmerelement einen Mitnehmersteg für das Federelement aufweist, wobei letzteres zwei Federenden hat, die derart ausgebildet sind, dass diese zu beiden Seiten des Mitnehmerstegs liegen und zu beiden Seiten des Anschlagelements in jeweils eine der Aussparungen in der Gehäuseschale eingreifen und wobei das Gehäuse ein Abdeckelement aufweist, sieht die Erfindung vor, dass die zentrale Ausnehmung des Gehäuses randseitig mit einer Stufe versehen ist, und dass das Mitnehmerelement zwei radial überstehende Laschen aufweist, wobei das Mitnehmerelement mit den Laschen auf der Stufe der Ausnehmung des Gehäuses gleitend aufliegt und wobei das Mitnehmerelement über die zwischen der Stufe und dem Abdeckelement gleitgeführten Laschen axial gesichert ist.In a Rückholfedereinrichtung for door or window fittings, with a rotatably mounted in a housing against a restoring force driver element which has a central axis to a rotational axis a square recess for receiving a square pin rotatably connected to at least one rotatably or pivotally mounted handle of the fitting, wherein the restoring force is generated by a spring element, wherein the housing has a housing shell, which is provided for receiving the driver element and the spring element with a central recess, wherein the housing shell radially adjacent to the recess has two recesses, between which a stop element for the spring element is formed, wherein the driver element has a Mitnehmersteg for the spring element, the latter having two spring ends which are formed such that they lie on both sides of the Mitnehmerstegs and on both sides of the stop element in each e engage in the recesses in the housing shell and wherein the housing has a cover, the invention provides that the central recess of the housing is provided at the edge with a step, and in that the driver element has two radially protruding tabs, wherein the driver element with the tabs on the step of the recess of the housing slidably rests and wherein the driver element via the slides between the step and the cover is axially secured.
Betätigt man den Griff des Beschlags wird über den Vierkantstift das Mitnehmerelement der Rückholfedereinrichtung im Gehäuse gedreht. Dabei lenkt der Mitnehmerstift am Mitnehmerelement eines der Federenden aus, welches sich innerhalb der jeweils zugeordneten Aussparung in Umfangsrichtung bewegen kann, während sich das andere Ende des Federelements am ortsfesten Anschlagelement im Gehäuse abstützt. Lässt man den Griff los, gelangt dieser aufgrund der auf das Mitnehmerelement einwirkenden Feder- bzw. Rückstellkraft wieder in seine Ausgangslage zurück. Die Aussparungen lassen sich aufgrund der einfachen Geometrie nahezu beliebig dimensionieren, so dass mit der erfindungsgemäßen Einrichtung im Vergleich zu herkömmlichen Konstruktionen problemlos auch größere Betätigungswinkel realisiert werden können.Pressing the handle of the fitting, the driving element of the return spring device is rotated in the housing over the square pin. In this case, the driver pin deflects on the driver element of one of the spring ends, which can move within the respective associated recess in the circumferential direction, while the other end of the spring element is supported on the stationary stop element in the housing. If you let go of the handle, this returns due to the force acting on the driver spring or restoring force back to its original position. The recesses can be dimensioned almost arbitrarily due to the simple geometry, so that with the device according to the invention in comparison to conventional constructions even larger operating angle can be realized easily.
Aufgrund der im Wesentlichen symmetrischen Lage der Aussparungen zu beiden Seiten des Anschlagelements und des in beiden Richtungen drehbaren Mitnehmerelements im Gehäuse kann man die Griffbewegung auch in die jeweils andere Richtung ausführen, so dass die Rückholfedereinrichtung problemlos sowohl für rechts- als auch für linksseitige Griffe eingesetzt werden kann; sie ist universell verwendbar. Die Rückholfedereinrichtung wird dabei von dem Gehäuse, dem Mitnehmerelement und dem Federelement - mithin von nur wenigen Bauteilen - gebildet. Sie hat daher einen äußerst einfachen und übersichtlichen Aufbau mit einfacher Geometrie, der rationell und damit kostengünstig herstellbar ist. Alle Bauteile lassen sich zudem rasch und bequem zu einer Einheit zusammenfügen, was eine einfache Montage gewährleistet. Das Mitnehmerelement ist stets leichtgängig und zuverlässig gelagert, ohne dass aufwendige Lagerelemente notwendig sind.Due to the substantially symmetrical position of the recesses on both sides of the stop element and the rotatable in both directions driver element in the housing you can perform the handle movement in the other direction, so that the return spring means are easily used for both right and left hand grips can; it is universally usable. The return spring device is thereby formed by the housing, the driver element and the spring element - thus only a few components. It therefore has a very simple and clear structure with a simple geometry that is rational and therefore inexpensive to produce. All components can also be quickly and easily assembled into a unit, which ensures easy installation. The driver element is always smoothly and reliably stored without complex bearing elements are necessary.
Die zentrale Ausnehmung in der Gehäuseschale ist im Wesentlichen kreisförmig ausgebildet, so dass diese ein Lager sowohl für das Mitnehmerelement als auch bei Bedarf für den Griff des Beschlags bildet.The central recess in the housing shell is substantially circular, so that it forms a bearing for both the driver element and, if necessary, for the handle of the fitting.
Die an die Ausnehmung angrenzenden Aussparungen sind bevorzugt bogenförmig und koaxial zur Ausnehmung ausgebildet, so dass sich die darin eingreifenden Federenden über den gesamten Bedienwinkel hinweg frei bewegen können. Dieser wird in Umfangsrichtung nur von den Anschlagflächen für das Mitnehmerelement und/oder für die Federenden des Federelements begrenzt, d.h. durch entsprechende Wahl der Bogenlänge der Aussparungen lassen sich auf einfache Weise unterschiedliche Bedienwinkel realisieren. Konstruktive Veränderungen oder gar zusätzliche Bauteile sind nicht erforderlich.The recesses adjacent to the recess are preferably arcuate and coaxial with the recess, so that the spring ends engaging therein over the entire Operating angle away can move freely. This is limited in the circumferential direction only by the abutment surfaces for the driver element and / or for the spring ends of the spring element, ie by appropriate choice of the arc length of the recesses can be realized in a simple manner different operating angle. Design changes or even additional components are not required.
Das bevorzugt mit der Gehäuseschale einstückige Anschlagelement bildet - ebenso wie die bogenförmigen Aussparungen - einen Bogen- oder Ringabschnitt. Es wird dabei in Umfangsrichtung von den Anschlagflächen der Aussparungen begrenzt, so dass sich die in die Aussparungen hineinragenden Enden des Federelements jeweils in beiden Betätigungsrichtungen an dem Anschlagelement abstützen können.The preferably integrally formed with the housing shell stop element forms - as well as the arcuate recesses - a bow or ring section. It is limited in the circumferential direction of the stop surfaces of the recesses, so that the protruding into the recesses ends of the spring element can be supported in both directions of actuation of the stop element.
Auch der Mitnehmersteg des Mitnehmerelements bildet einen Bogen- oder Ringabschnitt, wobei der Mittelpunktswinkel des Anschlagelements im Gehäuse und der Mittelpunktswinkel des Mitnehmerstegs am Mitnehmerelement bevorzugt gleich groß sind.Also, the Mitnehmersteg the driver element forms a bow or ring portion, wherein the center angle of the stop element in the housing and the center angle of the Mitnehmerstegs on the driver element are preferably the same size.
Befindet sich das Mitnehmerelement in seiner Ausgangs- oder Ruheposition, so liegt der Mitnehmersteg bevorzugt unmittelbar neben dem Anschlagelement der Gehäuseschale. Beide zusammen bilden dabei einen symmetrischen Kreissektor mit im Wesentlichen geraden Seitenflächen. An diesen können sich die Federenden des Federelements stets zuverlässig abstützen. Letzteres kann über den Griff, den Vierkantstift und das Mitnehmerelement jederzeit in beide Richtungen betätigt werden, indem der Mitnehmersteg jeweils ein Federende mitnimmt, während das andere Federende am ortsfesten Anschlagelement verbleibt. Das Federelement wird gespannt und führt - nach Loslassen des Griffs - das Mitnehmerelement und mit diesem den Griff wieder in seine Ausgangsposition zurück. Der Griff des Beschlags wird dadurch unabhängig vom Zustand einer gegebenenfalls vorhandenen Schlossfeder stets zuverlässig in seine meist horizontale Ausgangslage zurück gebracht.The entrainment element is in its home or rest position, the Mitnehmersteg is preferably immediately adjacent to the stop element of the housing shell. Both together form a symmetrical circular sector with substantially straight side surfaces. At these, the spring ends of the spring element can always support reliable. The latter can be operated via the handle, the square pin and the driving element at any time in both directions by the Mitnehmersteg each entrains a spring end, while the other end of the spring remains on the stationary stop element. The spring element is stretched and leads - after releasing the handle - the driver element and with this the handle back to its original position. The handle of the fitting is thus always reliably brought back into its mostly horizontal starting position, regardless of the state of a possibly existing lock spring.
Zur Lagerung und Führung des Federelements weist das Mitnehmerelement einen Halsabschnitt auf, wobei der Mitnehmersteg und der Halsabschnitt radial beabstandet sind, so dass das Federelement dazwischen angeordnet werden kann.For storage and guidance of the spring element, the driver element has a neck portion, wherein the driver web and the neck portion are radially spaced, so that the spring element can be arranged therebetween.
Das Gehäuse hat eine im Wesentlichen zylinderförmige Außenfläche. Diese kann - je nach Einbausituation -zumindest abschnittsweise seitlich abgeflacht sein, um z.B. die Rückholfedereinheit in einem schmalen Türschild unterbringen zu können.The housing has a substantially cylindrical outer surface. This can - depending on the installation situation - at least partially flattened laterally, for example, to accommodate the return spring in a narrow door plate can.
Eine weitere Ausführungsform der Erfindung sieht vor, dass die Außenfläche des Gehäuses radial ausgestellte Rastvorsprünge trägt oder bildet, um beispielsweise eine gesonderte Schild- oder Rosettenabdeckung festlegen zu können. Dies ist z.B. dann zweckmäßig, wenn das Gehäuse ein Anschlagelement für den Beschlag ist oder bildet. Es Lässt sich dann an einer Anschlagfläche für den Beschlag festlegen, wobei dazu im Gehäuse Schraubbohrungen ausgebildet sind. Zur Verdrehsicherung kann man das Gehäuse im Bereich der Schraubbohrungen mit Nocken versehen, die in korrespondiere Sacklöcher in der Anschlagfläche, meist einem Türblatt, eingreifen.A further embodiment of the invention provides that the outer surface of the housing carries or forms radially protruding latching projections in order to be able to define, for example, a separate shield or rosette cover. This is e.g. then expedient if the housing is or forms a stop element for the fitting. It can then be fixed to a stop surface for fitting, with screw holes being formed in the housing for this purpose. To prevent rotation one can provide the housing in the area of the screw holes with cams, which engage in corresponding blind holes in the stop surface, usually a door leaf.
Die Erfindung sieht weiter vor, dass die zentrale Ausnehmung des Gehäuses eine Lageröffnung für den Griff des Beschlags bildet. Dabei kann es günstig sein, wenn die Lageröffnung von einem Halsabschnitt begrenzt wird. Der Griff, insbesondere dessen Griffhals, findet dadurch eine stets sichere und wackelfreie Führung.The invention further provides that the central recess of the housing forms a bearing opening for the handle of the fitting. It may be advantageous if the bearing opening is limited by a neck portion. The handle, in particular the handle neck, thus finds an always safe and wobble-free guidance.
Bei einer weiteren Bauform der Rückholfedereinrichtung ist das Abdeckelement kraft- und/oder formschlüssig mit der Gehäuseschale verbindbar, insbesondere verklemm- und/oder verrastbar. Durch die Abdeckung werden sowohl das Mitnehmerelement als auch das Federelement in dem Gehäuse gesichert, sofern nicht das Mitnehmerelement für sich in der Gehäuseschale axial festgelegt ist. In diesem Fall wäre die Abdeckung entbehrlich.In a further design of the return spring device, the cover is non-positively and / or positively with the Housing shell connectable, in particular clamped and / or latched. Through the cover both the driver element and the spring element are secured in the housing, unless the driver element is fixed axially in the housing shell. In this case, the cover would be unnecessary.
Das Abdeckelement hat eine zentrische Ausnehmung, welche das Mitnehmerelement drehbar aufnimmt. Letzteres kann hierzu mit einem zusätzlichen Rand oder einem Vorsprung versehen sein, der drehbar in die Ausnehmung eingreift. Das Mitnehmerelement ist dadurch ergänzend oder alternativ im Gehäuse drehbar gelagert. Um eine geringe Bauhöhe zu gewährleisten, schließen das Abdeckelement und das Mitnehmerelement bündig miteinander ab.The cover has a central recess which rotatably receives the driver. The latter can be provided for this purpose with an additional edge or a projection which engages rotatably in the recess. The driver element is thereby additionally or alternatively rotatably mounted in the housing. In order to ensure a low overall height, close the cover and the driver element flush with each other.
Das Federelement ist bevorzugt eine Torsionsfeder oder eine Spiralfeder, die sich mit einer oder mit mehreren Windungen um den Halsabschnitt des Mitnehmerelements legt. Die Federenden des Federelements verlaufen dabei radial zur Drehachse des Mitnehmerelements, so dass sie stets zuverlässig am Anschlagelement des Gehäuses und am Mitnehmerstift des Mitnehmerelements anliegen können.The spring element is preferably a torsion spring or a spiral spring, which lays with one or more turns around the neck portion of the driver element. The spring ends of the spring element extend radially to the axis of rotation of the driver element, so that they can always reliably abut the stop element of the housing and the driver pin of the driver element.
Um eine kompakte und leicht zu montierende Rückholfedereinrichtung zu schaffen ist es vorteilhaft, wenn das Federelement eine Tiefe in axialer Richtung aufweist, die bevorzugt kleiner ist, als die axiale Tiefe der zentralen Ausnehmung in der Gehäuseschale. Die Tiefe des Federelements wird im Wesentlichen durch die Dicke des verwendeten Federelementmaterials und die Anzahl der Windungen bzw. Wicklungen bestimmt. In axialer Richtung gemessen ist jedoch die Tiefe des Federelements stets kleiner als die für die Aufnahme des Federelements vorgesehene Tiefe der Ausnehmung, so dass sowohl das Federelement als auch das Mitnehmerelement nicht über die Stirnseite der Gehäuseschale herausragen.In order to provide a compact and easy-to-install return spring device, it is advantageous if the spring element has a depth in the axial direction, which is preferably smaller than the axial depth of the central recess in the housing shell. The depth of the spring element is determined essentially by the thickness of the spring element material used and the number of windings or windings. Measured in the axial direction, however, the depth of the spring element is always smaller than that provided for receiving the spring element depth of the recess, so that both the spring element and the driver element do not protrude beyond the end face of the housing shell.
Die Tiefe des Mitnehmerstegs des Mitnehmerelements in axialer Richtung ist so bemessen, dass sie etwa der Tiefe des Federelements entspricht. Das heißt der Mitnehmersteg weist eine Tiefe auf, mit welcher er beide Enden des Federelements stets sicher erfasst.The depth of the Mitnehmerstegs of the driver element in the axial direction is dimensioned so that it corresponds approximately to the depth of the spring element. That is to say the carrier web has a depth with which it always reliably detects both ends of the spring element.
Bevorzugt wird die Feder vorgespannt montiert, d.h. die Federenden überkreuzen sich und liegen dadurch mit Vorspannung am Anschlagelement und am Mitnehmerstift an. Zur Anpassung an unterschiedliche Griff-Gewichte kann man das Federelement aber auch ohne Vorspannung einbringen. Konstruktive Veränderungen sind dazu nicht notwendig.Preferably, the spring is mounted biased, ie the spring ends cross each other and are characterized by bias on the stop element and the driving pin on. To adapt to different handle weights you can bring the spring element but also without bias. Constructive changes are not necessary.
Um den Montageaufwand weiter zu reduzieren, bilden das Gehäuse, das Mitnehmerelement und das Federelement eine vormontierte Einheit. Diese lassen sich aufgrund ihrer einfachen Geometrie nicht nur kostengünstig fertigen, sondern auch problemlos automatisiert fügen. Das Gehäuse, das Mitnehmerelement und das Federelement sind zudem allesamt symmetrisch ausgebildet, so dass die Rückholfedereinheit nicht nur beidseitig verwendbar ist, sondern auch in jeder beliebigen Lage eingebaut werden kann. Montage- und Bedienfehler werden dadurch sicher vermieden.To further reduce the assembly costs, the housing, the driver element and the spring element form a preassembled unit. These can be due to their simple geometry not only cost-effective manufacture, but also easily add automated. The housing, the driver element and the spring element are also all symmetrical, so that the return spring unit is not only used on both sides, but can also be installed in any position. Mounting and operating errors are thereby reliably avoided.
Ein Türbeschlag, für den selbständiger Schutz beansprucht wird, ist mit einer erfindungsgemäßen Rückholfedereinrichtung versehen, wobei wenigstens ein Griff an oder in einem Anschlagelement dreh- oder schwenkbar gelagert ist. Die Rückholfedereinrichtung nimmt in ihrem Mitnehmerelement den Vierkantstift des Beschlags auf, so dass beim Betätigen des Griffs das Mitnehmerelement gedreht wird. Das Federelement im Gehäuse der Rückholfedereinrichtung wird gespannt. Lässt man den Griff los, werden das Mitnehmerelement und der damit gekoppelte Griff - unabhängig vom Zustand einer Schlossfeder - von dem Federelement stets zuverlässig in die Ausgangsstellung zurück bewegt.A door fitting for which independent protection is claimed is provided with a return spring device according to the invention, wherein at least one handle is rotatably or pivotably mounted on or in a stop element. The return spring device receives in its driving element on the square pin of the fitting, so that upon actuation of the handle, the driver element is rotated. The spring element in the housing of the return spring device is tensioned. If you let go of the handle, the driver element and the coupled handle - regardless of the state of a lock spring - always reliably moved by the spring element back to the starting position.
Um eine dauerhaft zuverlässige Lagerung des Griffs zu gewährleisten ist zwischen diesem und dem Anschlagelement ein Führungsring vorgesehen. Dieser dient als Gleitlager. Er ist dabei bevorzugt drehfest mit dem Anschlagelement verbunden.In order to ensure a permanently reliable storage of the handle, a guide ring is provided between this and the stop element. This serves as a plain bearing. He is preferably rotatably connected to the stop element.
Eine Weiterbildung sieht vor, dass der Führungsring mit dem Gehäuse der Rückholfedereinrichtung kraft- und/oder formschlüssig verbindbar ist. Letztere ist damit an dem Anschlagelement befestigbar und zugleich verdrehsicher gehalten, was insbesondere dann von Vorteil ist, wenn das Anschlagelement ein Türschild ist. Dabei ist es zweckmäßig, wenn das Gehäuse der Rückholfedereinrichtung in das Türschild einsetzbar ist. Die Rückholfedereinrichtung wird dadurch vollständig von dem Schild verdeckt und ist nach außen hin nicht sichtbar, was sich günstig auf das Erscheinungsbild des Beschlages auswirkt.A further development provides that the guide ring with the housing of the return spring means is non-positively and / or positively connected. The latter is thus fastened to the stop element and at the same time held against rotation, which is particularly advantageous if the stop element is a door plate. It is expedient if the housing of the return spring device can be inserted into the door plate. The return spring means is completely covered by the shield and is not visible to the outside, which has a favorable effect on the appearance of the fitting.
Eine andere Ausführungsform sieht vor, dass der Führungsring mit dem Gehäuse der Rückholfedereinrichtung einstückig ist. Dies ist insbesondere dann vorteilhaft, wenn das Anschlagelement eine Rosette ist und wenn das Anschlagelement von dem Gehäuse der Rückholfedereinrichtung gebildet ist. Dadurch ergibt sich eine besonders kompakte Bauform. Um das Gehäuse der Rückholfedereinrichtung zu verdecken ist auf dem Anschlagelement eine Abdeckung festlegbar, die bevorzugt mit den radial ausgestellten Rastvorsprüngen am Gehäuse verrastbar ist.Another embodiment provides that the guide ring is integral with the housing of the return spring means. This is advantageous in particular when the stop element is a rosette and when the stop element is formed by the housing of the return spring device. This results in a particularly compact design. To cover the housing of the return spring means is on the Stop element a cover can be fixed, which is preferably latched to the radially issued locking projections on the housing.

Zwischen dem Handgriff 72 und dem Türschild 74 sitzt ein Führungsring 75 mit einer Lageröffnung 25 für den Griffhals 71. Der Ring 75 ist in einer runden Ausnehmung 76 im Türschild 74 eingesetzt und mittels umfangsseitig angeordneter Rastfedern 85 darin festgelegt. Er trägt überdies umfangsseitig radial ausgestellte Vorsprünge 77, die zur Verdrehsicherung in korrespondierende Aussparungen 79 im Rand der Ausnehmung 76 eingreifen. In dem Griffhals 71 des Griffs 72 ist stirnseitig ein Vierkantstift 80 drehfest eingesetzt, der mittels einer Madenschraube 82 axial gesichert wird. Der Vierkantstift 80 greift durch eine in das Türschild 74 rückseitig eingesetzte Rückholfedereinrichtung 10 hindurch in eine (nicht dargestellte) Schloßnuß eines Schlosses im Türblatt ein.Between the
Die Rückholfedereinrichtung 10 ist vorgesehen, um den Handgriff 72 nach dessen Betätigung stets zuverlässig in seine horizontale Ausgangsstellung zurück zu bringen. Sie ist als vormontierte Baueinheit ausgebildet und wird aus einem Gehäuse 20, einem Mitnehmerelement 40 und einem Federelement 50 zusammengesetzt.The return spring means 10 is provided to bring the
Das Gehäuse 20 hat eine Gehäuseschale 21 und ein rückseitig angebrachtes Abdeckelement 27 in Form eines Deckels, der im Wesentlichen die gleiche Außenkontur wie die Gehäuseschale 21 aufweist und mit Stiften 39 versehen ist. Letztere greifen kraft- und/oder reibschlüssig in entsprechende Bohrungen bzw. Ausnehmungen 59 in der Gehäuseschale 21 ein, so dass eine rasch zu montierende und dauerhaft feste Verbindung gewährleistet ist.The
In der Gehäuseschale 21 ist zur drehbaren Aufnahme des Mitnehmerelements 40 und des Federelements 50 eine zentrale kreisförmige Ausnehmung 22 ausgebildet. Radial angrenzend an die Ausnehmung 22 sind in der Gehäuseschale 21 zwei bogenförmige Aussparungen 30, 34 eingebracht, die in Umfangsrichtung U jeweils von Endflächen 31, 32 bzw. 35, 36 begrenzt werden. Mittig zwischen den Aussparungen 30, 34 ist ein Anschlagelement 26 für das Federelement 50 ausgebildet, das ebenfalls einen Bogen-oder Ringabschnitt bildet. Man erkennt, dass die Aussparungen 30, 34 koaxial zur Ausnehmung 22 und symmetrisch zum Anschlagelement 26 liegen, wobei die Endfläche 31 der Aussparung 30 und die Endfläche 35 der Aussparung 34 zugleich die Begrenzungsflächen des Anschlagelements 26 bilden (siehe dazu auch
Auf der dem Türschild 74 zugewandten Seite bildet die Ausnehmung 22 im Gehäuse 20 eine Öffnung 58, die im Durchmesser der Aussparung 79 im Türschild 74 entspricht. Setzt man die Rückholfedereinrichtung 10 rückseitig in das Türschild 74 ein, greift der Führungsring 75 mit seinen Rastfedern 85 kraft- und/oder formschlüssig in die Öffnung 58 und damit in das Gehäuse 20 ein, so dass die Rückholfedereinrichtung 10 fest mit dem Türschild 74 verbunden ist. Randseitig in der Öffnung 58 eingebrachte Aussparungen 57 nehmen die radial ausgestellten Vorsprünge 77 des Führungsrings 75 auf, so dass auch das Gehäuse 20 verdrehsicher in dem Türschild 74 fixiert ist.On the side facing the

Wie
Koaxial zur Drehachse A weist das Mitnehmerelement 40 einen Halsabschnitt 46 auf, wobei der Mitnehmersteg 44 und der Halsabschnitt 46 zur Aufnahme des Federelements 50 radial beabstandet sind.Coaxially to the axis of rotation A, the
Das Federelement 50 ist bevorzugt eine Torsionsfeder oder eine Spiralfeder, die sich mit einer oder mit mehreren Windungen um den Halsabschnitt 46 des Mitnehmerelements 40 legt. Sie hat ferner zwei radial zur Drehachse A abgewinkelte Federenden 52, 53, die zu beiden Seiten des Mitnehmerstegs 44 liegen und zu beiden Seiten des Anschlagelements 26 in jeweils eine Aussparung 30, 34 der Gehäuseschale 21 eingreifen. Die Federenden 52, 53 schließen mithin den vom Anschlagelement 26 und vom Mitnehmersteg 44 gebildeten ringförmigen Kreissektor ein, wobei die Seitenflächen 31, 35 des Anschlagelements 26 bzw. der Aussparungen 30, 34 als Anschlagflächen für die Federenden 52, 53 dienen.The
Dreht sich das Mitnehmerelement 40 durch eine Betätigung des Griffs 72 im Gehäuse 20 in eine Richtung, z.B. nach rechts, so wird das Ende 52 der Feder 50 von dem Mitnehmersteg 44 in Umfangsrichtung U nach rechts ausgelenkt, während sich das andere Ende 53 an der Anschlagfläche 31 in der Aussparung 30 bzw. am Anschlagelement 26 abstützt. Die Feder 50 wird gespannt. Lässt man den Griff 72 los, dreht die Feder 50 das Mitnehmerelement 40 über den Mitnehmersteg 44 wieder zurück in seine Ausgangsposition vor das Anschlagelement 26. Der Griff 72 wird über den Vierkantstift 80 in seine horizontale Lage zurück bewegt.By turning the
Während der Drehbewegung des Griffs 72 bewegt sich das Federende 52 in der bogenförmigen Aussparung 34 bis es an der zweiten Begrenzungsfläche 36 anschlägt. Diese bildet mithin einen Anschlag sowohl für die Drehbewegung des Mitnehmerelements 40 als auch für die Schwenkbewegung des Griffs 72. Aufgrund der relativ großen Bogenlänge der Aussparung 34 und des Winkelabstandes von 60° zwischen den Anschlagflächen 35 und 36, kann der Griff 72 - im Vergleich zu herkömmlichen Beschlägen mit Rückholfedereinrichtungen - eine relativ große Schwenkbewegung ausführen.During the rotational movement of the
Aufgrund der symmetrischen Ausbildung der Rückholfedereinrichtung 10, insbesondere der symmetrischen Ausbildung der Aussparungen 30, 34, kann man das Mitnehmerelement 40 über den Griff 72 und den Vierkantstift 80 auch in die andere Richtung nach links drehen. In diesem Fall bewegt der Mitnehmersteg 44 das Federende 53 in der Aussparung 30 nach links, während sich das Federende 52 an der Anschlagfläche 35 abstützt. Die Rückholfedereinrichtung 10 kann mithin universell sowohl für eine Rechtswie für eine Linksbetätigung eingesetzt werden, ohne dass ein anderes Bauteil benötigt wird oder dass es konstruktiver Änderungen bedarf.Due to the symmetrical design of the return spring means 10, in particular the symmetrical design of the
Man kann den Schwenkwinkel des Mitnehmerelements 40 innerhalb des Gehäuses 20 bei Bedarf auch auf z.B. 40° begrenzen, indem die Bogenlänge der Aussparungen 30, 34 entsprechend kleiner gewählt wird. Eine weitere Alternative sieht vor, dass nicht die Federenden 52, 53 an den Begrenzungsflächen 32, 36 der Aussparungen 30, 34 zum Anliegen kommen, sondern beispielsweise die Laschen 43 des Mitnehmerelements 40. Auch dadurch Lässt sich die Schwenkbewegung begrenzen, damit beispielsweise das Federelement 50 nicht überlastet wird.If necessary, the pivoting angle of the
Der Handgriff 72 des Beschlags 70 ist mit seinem Griffhals 71 in dem Anschlagelement 74 und damit im Gehäuse 20 der Rückholfedereinrichtung 10 drehbar gelagert. Die zentrale Ausnehmung 22 des Gehäuses 20 bildet dazu die Lageröffnung 25 für den Griffhals 71, welche bevorzugt von einem Halsabschnitt 38 begrenzt ist (siehe
Um das Gehäuse 20 nach außen hin optisch zu verkleiden, ist eine Abdeckung 78 vorgesehen, die auf die Gehäuseschale 21 aufgesetzt wird. Zur Festlegung der Abdeckung 78 trägt die im Wesentlichen zylinderförmige Außenfläche 28 des Gehäuses 20 radial ausgestellte Rastvorsprünge 29, die mit dem (nicht näher bezeichneten) Innenumfang der Abdeckung 78 verrastbar sind.
