Definitions
- the invention relates to a locking device for closing a door or window sash, with a spring piston acted upon by a spring for applying a closing force to a closer shaft and a damping piston for damping the movement of the closer shaft according to the preamble of claim 1.
- Locking devices for closing a door or window sash with a spring piston, a closer shaft and a damping piston or components of such a locking device are known from the prior art, for example DE 102 59 237 A1 or EP 2 372 065 B1 . These provide that a piston is formed by a shape-stabilizing insert, which is covered with a plastic cover layer. This means that sufficiently high forces can be transmitted, while the advantageous friction properties of the plastic are retained.
- US 5,901,412 discloses an overhead door closer with a one-piece plunger.
- WO 2004/003076 A1 discloses a drive device whose piston has a metal inlay and is covered with plastic (POM).
- DE 10 2014 103 580 B3 shows a hydraulic damper with a housing for a door closer.
- the invention is based on the object of enabling a cost-effective provision of a locking device using simple structural means.
- the invention solves this problem by a locking device with the features of claim 1.
- the damping piston or the spring piston then has a piston body which is originally formed from the plastic or liquid state and is designed to be monolithic.
- the piston body is thus formed monolithically from the plastic or liquid state by means of primary shaping. This contributes to a cost-effective design of the damping piston or the spring piston and the locking device as a whole.
- the piston body is in particular completely made of a uniform or identical material (monolithic design), so that the piston body is free of inserts (design of the piston body without inserts).
- the locking device can be a door drive for operating a door or window leaf or a door closer for closing a door or window leaf.
- the damping piston is in particular designed separately from the spring piston.
- the spring piston and the damping piston can each have a piston body which is originally formed from the plastic or liquid state and is monolithic. Since the piston body of the spring piston and the damping piston are also designed to be monolithic by way of primary molding from the plastic or liquid state, the structure of the damping piston and the spring piston and thus the closing device as a whole are once again simplified.
- the spring piston is designed using conventional machining, for example made of steel. This can already be used to realize an advantageous locking device.
- the piston body of the damping piston is formed by injection molding and the piston body of the spring piston is formed by die casting.
- the damping piston is formed by injection molding from plastic, in particular from polyoxymethylene (POM).
- POM polyoxymethylene
- the spring piston is made of non-ferrous metal, namely a zinc alloy (zinc die-casting process).
- the damping piston can expediently have a roller for engagement with the closer shaft, the roller having axle sections and roller sections which are radially expanded and axially spaced relative to the axle sections, the roller being mounted on the damping piston by means of the axle sections.
- the roller rests over the axle sections over a large area on trough-shaped support surfaces formed on the damping piston, preferably where the number of axle sections corresponds to the number of support surfaces.
- the support surfaces are designed in such a way that they have a vertical Limit circular cylinders, especially by an angle of 180° to 190°. This allows the roller to be inserted, in particular clipped, into the damping piston. This largely prevents the roll from falling out, which makes assembly easier.
- the damping piston can have an overload valve, a check valve, a sealing ring and/or an O-ring. This allows additional functions to be fulfilled by the damping piston.
- the damping piston can have a preferably circumferential groove on its outer surface (jacket surface) in which the sealing ring and the O-ring are arranged.
- the sealing ring can surround the O-ring radially outwards.
- the damping piston can have a first section facing away from the closer shaft when installed and a second section which tapers radially in sections over the circumference (facing the closer shaft).
- the overload valve, the check valve, the sealing ring and/or the O-ring can be arranged in the first section.
- the damping roller can be arranged in the second section.
- the outer surface (jacket surface) of the damping piston can form a running surface that runs on the inner wall (cylindrical bore) in the housing of the locking device.
- the sealing ring only serves to seal the pressure space on the damping side from the pressure-free space in which the closer shaft is located.
- the spring piston can have a roller for engagement with the closer shaft, the roller being mounted on the spring piston directly by means of axle sections or by means of a bearing bush.
- the bearing surface on the piston can be increased with a bearing bush.
- the one or more bearing bushes can be made of metal, for example aluminum or brass, or of a high-pressure-resistant plastic, for example polyimides.
- the spring piston can be designed to be groove-free on its outer surface (jacket surface). This contributes to a structurally simple and stable design of the spring piston.
- a large-area running surface can be provided, with the structure of the spring piston not being weakened.
- the spring piston can have, in particular, circumferential grooves on its outer surface (jacket surface) for receiving a slide ring, a sealing ring or an O-ring and/or the spring piston can have a combination valve (combination of overload and check valve).
- the rings can be arranged in the respective groove and take on a guiding and/or sealing function. To provide a sufficient leadership function, it is conceivable that two axially spaced slide rings are arranged in corresponding grooves on the spring piston.
- the spring piston can have axially projecting foot sections at its end facing the closer shaft in the installed state and/or optionally the damping piston can have foot receiving sections for receiving the foot sections of the spring piston at its end facing the closer shaft in the installed state.
- the closer shaft can be bridged, so that a direct force transmission from the spring piston to the damping piston can take place, particularly when closing the door or window sash.
- the load on the damping piston in particular on its contact surfaces, can be reduced by the roller acting on the damping piston to engage with the closer shaft (damping piston roller).
- the foot sections extend in the axial direction away from the spring piston.
- the outer surface (outer surface) of the spring piston can be continued through the foot sections. This means that the contour of the spring piston continues without weakening.
- the outer surface forms a running surface running in the closing device, for example in the case of a spring piston made of plastic that is not designed according to the invention, this contributes to optimized guidance of the spring piston.

Description
Die Erfindung betrifft eine Schließvorrichtung zum Schließen eines Tür- oder Fensterflügels, mit einem durch eine Feder beaufschlagten Federkolben zum Aufbringen einer Schließkraft auf eine Schließerwelle und einem Dämpfungskolben zur Dämpfung der Bewegung der Schließerwelle gemäß dem Oberbegriff von Anspruch 1.The invention relates to a locking device for closing a door or window sash, with a spring piston acted upon by a spring for applying a closing force to a closer shaft and a damping piston for damping the movement of the closer shaft according to the preamble of claim 1.
Schließvorrichtungen zum Schließen eines Tür- oder Fensterflügels mit einem Federkolben, einer Schließerwelle sowie einem Dämpfungskolben bzw. Komponenten einer solchen Schließvorrichtung sind aus dem Stand der Technik bekannt, bspw. aus
Allerdings ist problematisch, dass der Herstellungsaufwand bedingt durch die regelmäßig spanende Herstellung eines Einlegeteils und den danach erfolgenden Überzug des Einlegeteils mit Kunststoff hoch ist. Der Herstellungsaufwand führt zu hohen Kosten solcher Schließvorrichtungen.However, it is problematic that the manufacturing effort is high due to the regular machining of an insert and the subsequent coating of the insert with plastic. The manufacturing effort leads to high costs for such locking devices.
Der Erfindung liegt die Aufgabe zugrunde, mit einfachen konstruktiven Mitteln eine kostengünstige Bereitstellung einer Schließvorrichtung zu ermöglichen.The invention is based on the object of enabling a cost-effective provision of a locking device using simple structural means.
Die Erfindung löst diese Aufgabe durch eine Schließvorrichtung mit den Merkmalen des Anspruchs 1. Danach weist der Dämpfungskolben oder der Federkolben einen Kolbenkörper auf, der aus dem plastischen oder flüssigen Zustand urgeformt und monolithisch ausgebildet ist.The invention solves this problem by a locking device with the features of claim 1. The damping piston or the spring piston then has a piston body which is originally formed from the plastic or liquid state and is designed to be monolithic.
Dadurch ist der Aufbau des Dämpfungskolbens oder des Federkolbens und damit der Schließvorrichtung insgesamt erheblich vereinfacht, da die Anzahl und die Komplexität der Fertigungsschritte reduziert sind. So wird der Kolbenkörper im Wege des Urformens aus dem plastischen oder flüssigen Zustand monolithisch ausgebildet. Dies trägt zu einer kostengünstigen Ausgestaltung des Dämpfungskolbens oder des Federkolbens und der Schließvorrichtung insgesamt bei. Der Kolbenkörper ist insbesondere vollständig aus einem einheitlichen bzw. identischen Material ausgebildet (monolithische Ausgestaltung), so dass der Kolbenkörper frei von Einlegeteilen ist (einlegeteilfreie Ausgestaltung des Kolbenkörpers).As a result, the structure of the damping piston or the spring piston and thus the locking device as a whole is considerably simplified, since the number and complexity of the manufacturing steps are reduced. The piston body is thus formed monolithically from the plastic or liquid state by means of primary shaping. This contributes to a cost-effective design of the damping piston or the spring piston and the locking device as a whole. The piston body is in particular completely made of a uniform or identical material (monolithic design), so that the piston body is free of inserts (design of the piston body without inserts).
Bei der Schließvorrichtung kann es sich um einen Türantrieb zur Betätigung eines Tür- oder Fensterflügels oder einen Türschließer zum Schließen eines Tür- oder Fensterflügels handeln. Der Dämpfungskolben ist insbesondere separat zum Federkolben ausgebildet.The locking device can be a door drive for operating a door or window leaf or a door closer for closing a door or window leaf. The damping piston is in particular designed separately from the spring piston.
Im Rahmen einer bevorzugten Ausgestaltung können der Federkolben und der Dämpfungskolben jeweils einen Kolbenkörper aufweisen, der aus dem plastischen oder flüssigen Zustand urgeformt und monolithisch ausgebildet ist. Indem auch der Kolbenkörper des Federkolbens und des Dämpfungskolbens im Wege des Urformens aus dem plastischen oder flüssigen Zustand monolithisch ausgebildet sind, sind der Aufbau des Dämpfungskolbens sowie des Federkolbens und damit der Schließvorrichtung insgesamt abermals vereinfacht. Alternativ hierzu ist denkbar, dass der Federkolben konventionell spanend ausgestaltet ist, bspw. aus Stahl. Bereits hiermit kann eine vorteilhafte Schließvorrichtung realisiert werden.As part of a preferred embodiment, the spring piston and the damping piston can each have a piston body which is originally formed from the plastic or liquid state and is monolithic. Since the piston body of the spring piston and the damping piston are also designed to be monolithic by way of primary molding from the plastic or liquid state, the structure of the damping piston and the spring piston and thus the closing device as a whole are once again simplified. Alternatively, it is conceivable that the spring piston is designed using conventional machining, for example made of steel. This can already be used to realize an advantageous locking device.
Weiter erfindungsgemäß sind der Kolbenkörper des Dämpfungskolbens durch Spritzgießen und der Kolbenkörper des Federkolbens durch Druckguss ausgebildet. Hiermit lassen sich der Federkolben und der Dämpfungskolben mit einfachen konstruktiven Mitteln in hinreichender Stabilität fertigen. Im Konkreten ist der Dämpfungskolben durch Spritzgießen aus Kunststoff, insbesondere aus Polyoxymethylen (POM), ausgebildet. Der Federkolben ist aus Nichteisenmetall ausgebildet, und zwar aus einer Zinklegierung (Zinkdruckgussverfahren).Further according to the invention, the piston body of the damping piston is formed by injection molding and the piston body of the spring piston is formed by die casting. This allows the spring piston and the damping piston to be manufactured with sufficient stability using simple design means. Specifically, the damping piston is formed by injection molding from plastic, in particular from polyoxymethylene (POM). The spring piston is made of non-ferrous metal, namely a zinc alloy (zinc die-casting process).
In zweckmäßiger Weise kann der Dämpfungskolben eine Rolle zum Eingriff mit der Schließerwelle aufweisen, wobei die Rolle Achsabschnitte und relativ zu den Achsabschnitten radial erweiterte und axial zueinander beabstandete Rollenabschnitte aufweist, wobei die Rolle mittels der Achsabschnitte am Dämpfungskolben gelagert ist. Damit ist ein hinreichend stabile Lagerung der Rolle (Dämpfungsrolle) am Dämpfungskolben geschaffen. Dabei liegt die Rolle über die Achsabschnitte großflächig auf am Dämpfungskolben ausgebildeten muldenförmigen Auflageflächen auf, vorzugsweise wobei die Zahl der Achsabschnitte mit der Zahl der Auflageflächen übereinstimmt. Die Auflageflächen sind derart ausgebildet, dass diese einen senkrechten Kreiszylinder begrenzen, insbesondere um einen Winkel von 180° bis 190°. Dadurch kann die Rolle in den Dämpfungskolben eingesetzt, insbesondere eingeclipst, werden. Ein Herausfallen der Rolle wird somit weitestgehend vermieden, was die Montage erleichtert.The damping piston can expediently have a roller for engagement with the closer shaft, the roller having axle sections and roller sections which are radially expanded and axially spaced relative to the axle sections, the roller being mounted on the damping piston by means of the axle sections. This creates a sufficiently stable storage of the roller (damping roller) on the damping piston. The roller rests over the axle sections over a large area on trough-shaped support surfaces formed on the damping piston, preferably where the number of axle sections corresponds to the number of support surfaces. The support surfaces are designed in such a way that they have a vertical Limit circular cylinders, especially by an angle of 180° to 190°. This allows the roller to be inserted, in particular clipped, into the damping piston. This largely prevents the roll from falling out, which makes assembly easier.
Im Konkreten kann der Dämpfungskolben ein Überlastventil, ein Rückschlagventil, einen Dichtring und/oder einen O-Ring aufweisen. Hierdurch lassen sich durch den Dämpfungskolben weitere Funktionen erfüllen. Der Dämpfungskolben kann an seiner Außenfläche (Mantelfläche) eine vorzugsweise umlaufend ausgebildete Nut aufweisen, in welcher der Dichtring und der O-Ring angeordnet sind. Dabei kann der Dichtring den O-Ring nach radial außen umgeben.Specifically, the damping piston can have an overload valve, a check valve, a sealing ring and/or an O-ring. This allows additional functions to be fulfilled by the damping piston. The damping piston can have a preferably circumferential groove on its outer surface (jacket surface) in which the sealing ring and the O-ring are arranged. The sealing ring can surround the O-ring radially outwards.
Der Dämpfungskolben kann einen ersten, im eingebauten Zustand von der Schließerwelle abgewandten Abschnitt und einen zweiten, abschnittsweise über den Umfang radial verjüngten Abschnitt aufweisen (der Schließerwelle zugewandt). In dem ersten Abschnitt können das Überlastventil, das Rückschlagventil, der Dichtring und/oder der O-Ring angeordnet sein. In dem zweiten Abschnitt kann die Dämpfungsrolle angeordnet sein. Insbesondere bei einer Ausgestaltung des Dämpfungskolbens aus Kunststoff kann die Außenfläche (Mantelfläche) des Dämpfungskolbens eine Lauffläche bilden, die im Gehäuse der Schließvorrichtung an der Innenwand (zylindrische Bohrung) läuft. Der Dichtring dient lediglich zur Abdichtung des dämpfungsseitigen Druckraums gegenüber dem druckfreien Raum, in dem sich die Schließerwelle befindet.The damping piston can have a first section facing away from the closer shaft when installed and a second section which tapers radially in sections over the circumference (facing the closer shaft). The overload valve, the check valve, the sealing ring and/or the O-ring can be arranged in the first section. The damping roller can be arranged in the second section. In particular, in a design of the damping piston made of plastic, the outer surface (jacket surface) of the damping piston can form a running surface that runs on the inner wall (cylindrical bore) in the housing of the locking device. The sealing ring only serves to seal the pressure space on the damping side from the pressure-free space in which the closer shaft is located.
Im Rahmen einer bevorzugten Ausgestaltung kann der Federkolben eine Rolle zum Eingriff mit der Schließerwelle aufweisen, wobei die Rolle mittels Achsabschnitten unmittelbar oder mittels einer Lagerbuchse an dem Federkolben gelagert ist. Somit lässt sich eine stabile Lagerung der Rolle des Federkolbens am Federkolben realisieren. Mit einer Lagerbuchse kann die Lagerfläche am Kolben vergrößert werden. Dies ist insbesondere bei einer nicht erfindungsgemäßen Ausgestaltung des Federkolbens aus Kunststoff von Vorteil. Die eine oder mehrere Lagerbuchsen können aus Metall ausgebildet sein, bspw. aus Aluminium oder Messing, oder aus einem hochdruckfesten Kunststoff, bspw. aus Polyimiden. In vorteilhafter Weise kann der Federkolben an seiner Außenfläche (Mantelfläche) nutfrei ausgebildet sein. Dies trägt zu einer konstruktiv einfachen und stabilen Ausgestaltung des Federkolbens bei. So kann insbesondere bei einer nicht erfindungsgemäßen Ausgestaltung des Federkolbens aus Kunststoff eine großflächige Lauffläche bereitgestellt werden, wobei die Struktur des Federkolbens nicht geschwächt ist.As part of a preferred embodiment, the spring piston can have a roller for engagement with the closer shaft, the roller being mounted on the spring piston directly by means of axle sections or by means of a bearing bush. This makes it possible to achieve a stable storage of the role of the spring piston on the spring piston. The bearing surface on the piston can be increased with a bearing bush. This is particularly advantageous if the spring piston is made of plastic and is not designed according to the invention. The one or more bearing bushes can be made of metal, for example aluminum or brass, or of a high-pressure-resistant plastic, for example polyimides. Advantageously, the spring piston can be designed to be groove-free on its outer surface (jacket surface). This contributes to a structurally simple and stable design of the spring piston. In particular, in a design of the spring piston made of plastic that is not according to the invention, a large-area running surface can be provided, with the structure of the spring piston not being weakened.
Alternativ hierzu kann der Federkolben an seiner Außenfläche (Mantelfläche) insbesondere umlaufende Nuten zur Aufnahme eines Gleitrings, eines Dichtungsrings oder eines O-Rings aufweisen und/oder kann der Federkolben ein Kombiventil (Kombination aus Überlast- und Rückschlagventil) aufweisen. Die Ringe können in der jeweiligen Nut angeordnet werden und eine Führungs- und/oder Dichtungsfunktion übernehmen. Zur Bereitstellung einer hinreichenden Führungsfunktion ist denkbar, dass zwei axial voneinander beabstandete Gleitringe im entsprechenden Nuten am Federkolben angeordnet sind.Alternatively, the spring piston can have, in particular, circumferential grooves on its outer surface (jacket surface) for receiving a slide ring, a sealing ring or an O-ring and/or the spring piston can have a combination valve (combination of overload and check valve). The rings can be arranged in the respective groove and take on a guiding and/or sealing function. To provide a sufficient leadership function, it is conceivable that two axially spaced slide rings are arranged in corresponding grooves on the spring piston.
Im Rahmen einer bevorzugten Ausgestaltung kann der Federkolben an seinem im eingebauten Zustand der Schließerwelle zugewandten Ende axial abragende Fußabschnitte aufweisen und/oder optional kann der Dämpfungskolben an seinem im eingebauten Zustand der Schließerwelle zugewandten Ende Fußaufnahmeabschnitte zur Aufnahme der Fußabschnitte des Federkolbens aufweisen. Dadurch kann die Schließerwelle überbrückt werden, so dass insbesondere beim Schließen des Tür- oder Fensterflügels eine direkte Kraftübertragung vom Federkolben auf den Dämpfungskolben erfolgen kann. Durch ein solches Überbrücken der Schließerwelle mittels der Fußabschnitte kann die Belastung des Dämpfungskolbens, insbesondere an dessen Auflageflächen, durch die auf den Dämpfungskolben wirkende Rolle zum Eingriff mit der Schließerwelle (Dämpfungskolbenrolle) reduziert werden. Die Fußabschnitte erstrecken sich in axialer Richtung vom Federkolben weg.As part of a preferred embodiment, the spring piston can have axially projecting foot sections at its end facing the closer shaft in the installed state and/or optionally the damping piston can have foot receiving sections for receiving the foot sections of the spring piston at its end facing the closer shaft in the installed state. This allows the closer shaft to be bridged, so that a direct force transmission from the spring piston to the damping piston can take place, particularly when closing the door or window sash. By bridging the closer shaft in this way by means of the foot sections, the load on the damping piston, in particular on its contact surfaces, can be reduced by the roller acting on the damping piston to engage with the closer shaft (damping piston roller). The foot sections extend in the axial direction away from the spring piston.
In vorteilhafter Weise kann die Außenfläche (Mantelfläche) des Federkolbens durch die Fußabschnitte fortgesetzt werden. Dadurch wird die Kontur des Federkolbens ohne Schwächung fortgesetzt. Insbesondere dann, wenn die Außenfläche eine in der Schließvorrichtung laufende Lauffläche bildet, bspw. bei einer nicht erfindungsgemäßen Ausgestaltung des Federkolbens aus Kunststoff, trägt dies zu einer optimierten Führung des Federkolbens bei.Advantageously, the outer surface (outer surface) of the spring piston can be continued through the foot sections. This means that the contour of the spring piston continues without weakening. In particular, if the outer surface forms a running surface running in the closing device, for example in the case of a spring piston made of plastic that is not designed according to the invention, this contributes to optimized guidance of the spring piston.
