Definitions

  • doors namely garden doors or doors in barriers, fences and hedges are simple constructions. They are designed as single-leaf doors, so they only have a single door leaf, which is hinged on one side and can be swung open on both sides.
  • Such doors are built into wire mesh fences, for example. These wire mesh fences have vertical tubular steel posts that are offset at intervals, and the areas between the tubular steel posts are braced with a wire mesh.
  • High quality versions are made with galvanized tubular steel posts, the upper end of which is closed by a chrome steel or aluminum cap with a frustoconical shape. A more or less coarse rectangular-meshed wire mesh or a so-called diagonal wire mesh is braced between the individual posts as the wire mesh.
  • two posts are set with a little more distance than the width of the door to be used.
  • Hinges are provided on one pillar, into which a door made of a square or rectangular frame is inserted.
  • These frames are usually made of the same pipe material as the tubular steel posts, and they are either curved by a right angle for each of the four corners or screwed together with fittings in the form of bends from straight pipe sections or welded together from pipe parts.
  • the area within the frame is braced with a wire mesh in the same way as the fence.
  • FR 2 380 406 It is a double-sided effective door closer, which, however, is not suitable for a garden door due to its construction. The construction is not housed in a closed housing and has many sharp corners and edges that pose a risk of injury.
  • this door closer is designed to be visible as an open mechanism, and several individual parts are visible on it, including a spiral spring, which is probably covered by an angle iron, but is otherwise openly exposed to the weather. Since there is only a single spring, the closing force is rather modest in view of the associated dimensions. In addition, it is not possible to steplessly preload the spring.
  • GB 395 135 A (BROOKES & ADAMS LTD; ARNOLD EDWIN discloses (page 2, line 94 - page 3, line 85; Figures 1-4) a door closer for use in or on a vertical door post or to be placed firmly on such, including a bolt 13, which is mounted at each of its two ends in a disk 12, the two disks 12 being firmly connected to one another via a radially spaced bridge 10 running parallel to the bolt 13.
  • the bolt 13 carries a rotary disk 23 in its longitudinal center, which radial to extends to the inside of the bridge 10, with a steel spring 9, 10 each being guided around the bolt 1 with several turns above and below the turntable 5.
  • the door closer after PCT / EP2017 / 068466 is only effective in one direction and its structure and mode of operation are significantly different from what is disclosed here.
  • the door closer after US 2 102 321 A (KEENE WILLIAM J ) has only one spring and this is not not not not arranged between the disks (12, 16).

Description

Viele Türen, namentlich etwa Gartentüren oder Türen in Abschrankungen, Zäunen und Hecken sind einfache Konstruktionen. Sie sind als Einflügel-Türen ausgeführt, weisen also bloss ein einzelnes Türblatt auf, welches auf einer Seite angeschlagen ist und auf beide Seiten aufgeschwenkt werden kann. Solche Türen werden zum Beispiel in Drahtgeflecht-Zäunen verbaut. Diese Drahtgeflecht-Zäune weisen in Abständen versetzte, vertikale einbetonierte Stahlrohrpfosten auf, und die Bereiche zwischen den Stahlrohrpfosten sind mit einem Drahtgeflecht verspannt. Ausführungen in hoher Qualität werden mit verzinkten Stahlrohrpfosten erstellt, deren oberes Ende von einer Chromstahl- oder Aluminiumkappe mit stumpfkegeliger Form verschlossen wird. Als Drahtgeflecht wird ein mehr oder weniger grobes rechteckmaschiges Drahtgeflecht oder ein sogenanntes Diagonal-Drahtgeflecht zwischen den einzelnen Pfosten verspannt. Wo eine Türe eingebaut werden soll, werden zwei Pfosten mit wenig mehr Abstand als die Breite der einzusetzenden Türe gesetzt. Am einen Pflosten werden Scharniere vorgesehen, in welche eine Türe aus einem quadratischen oder rechteckig gestalteten Rahmen eingesetzt wird. Diese Rahmen sind in der Regel aus dem gleichen Rohrmaterial gefertigt wie die Stahlrohrpfosten, und sie werden entweder um je einen rechten Winkel für die vier Ecken gekrümmt oder mit Fittingen in Form von Bögen aus geraden Rohrabschnitten zusammengeschraubt oder aus Rohrteilen zusammengeschweisst. Der Bereich innerhalb des Rahmens wird in gleicher Weise wie der Zaun mit einem Drahtgeflecht verspannt. Es ist klar, dass es vielerlei ähnliche Konstruktionen gibt, mit blossen Stahlprofilen anstatt Rohren, zum Beispiel mit T-Profilen, oder mit minderwertigeren Materialien hergestellt, etwa aus Holz oder gewöhnlichem Baustahl, welcher zum Schutz vor Korrosion gestrichen wird. Zuweilen werden für luxuriöse Ausführungen von Abschrankungen auch Chromstahlpfosten gesetzt, zwischen diese zum Beispiel starke Glasplatten eingesetzt werden.Many doors, namely garden doors or doors in barriers, fences and hedges are simple constructions. They are designed as single-leaf doors, so they only have a single door leaf, which is hinged on one side and can be swung open on both sides. Such doors are built into wire mesh fences, for example. These wire mesh fences have vertical tubular steel posts that are offset at intervals, and the areas between the tubular steel posts are braced with a wire mesh. High quality versions are made with galvanized tubular steel posts, the upper end of which is closed by a chrome steel or aluminum cap with a frustoconical shape. A more or less coarse rectangular-meshed wire mesh or a so-called diagonal wire mesh is braced between the individual posts as the wire mesh. Where a door is to be installed, two posts are set with a little more distance than the width of the door to be used. Hinges are provided on one pillar, into which a door made of a square or rectangular frame is inserted. These frames are usually made of the same pipe material as the tubular steel posts, and they are either curved by a right angle for each of the four corners or screwed together with fittings in the form of bends from straight pipe sections or welded together from pipe parts. The area within the frame is braced with a wire mesh in the same way as the fence. It is clear that there are many similar constructions, with bare steel profiles instead of pipes, for example with T-profiles, or made with inferior materials, such as wood or ordinary structural steel, which is painted to protect against corrosion. Sometimes chrome steel posts are set for luxurious versions of barriers, with strong glass plates inserted between them, for example.

Bei allen diesen Abschrankungen und Zäunen stellt sich das Problem, dass eine eingebaute Türe oftmals nach dem Durchschreiten offen stehen gelassen wird. Zwar werden solche Türen entweder mit einer Türfalle und zugehörigem Schloss ausgeführt, oder mit einem Schieberiegel oder einem schwenkbaren Riegel, aber die Benützer der Türen schliessen diese nach dem Passieren der Türen oftmals nicht. Minderjährige vergessen sich, wenn sie in Gruppen eine solche Türe passieren, und so steht sie dann lange Zeit offen und die Abschrankung erfüllt ihren Zweck nicht, nämlich Dritten gegenüber deutlich ein Privatareal zu markieren. Ideal wäre eine Türe, die bei Nichtgebrauch stets geschlossen ist oder zumindest geschlossen erscheint, und die bei jedem Öffnen, das heisst bei jedem Aufschwenken, egal auf welche Seite hin aufgeschwenkt, nach dem Passieren von selbst immer in die Ausgangslage zurückschwenken würde und somit geschlossen bliebe.With all these barriers and fences, the problem arises that a built-in door is often left open after walking through. Such doors are designed either with a door latch and associated lock, or with a sliding bolt or a pivoting bolt, but the users of the doors often do not close them after passing through the doors. Minors forget themselves when they pass such a door in groups, and so it is then open for a long time and the barrier does not serve its purpose, namely to clearly mark a private area to third parties. A door that is always closed or at least appears closed when not in use would be ideal, and which would always swing back into its starting position automatically after passing through, i.e. when it was opened, i.e. when it was opened, regardless of the side, and would therefore remain closed .

Zu diesem Zweck gibt es im Stand der Technik freilich schon eine Vielzahl von Lösungen. Eine mögliche Lösung ist in FR 2 380 406 offenbart. Es handelt sich um einen zweiseitig wirksamen Türschliesser, der sich aber wegen seiner Konstruktion nicht für eine Gartentüre eignet. Die Konstruktion ist nicht in einem geschlossenen Gehäuse untergebracht und zeigt viele scharfe Ecken und Kanten, welche eine Verletzungsgefahr in sich bergen. Ausserdem ist dieser Türschliesser als offene Mechanik sichtbar ausgeführt, und es sind mehrere Einzelteile daran sichtbar, unter anderem eine Spiralfeder, die wohl von einem Winkeleisen abgedeckt ist, sonst aber offen der Witterung ausgesetzt ist. Da bloss eine einzige Feder vorhanden ist, ist in Anbetracht der zugehörigen Abmessungen die Schliesskraft eher bescheiden. Zudem ist es nicht möglich, die Feder stufenlos vorzuspannen. Insgesamt wirkt die Konstruktion wenig elegant und ist wohl auch aufwändig in der Herstellung und vor allem im Anbau. GB 395 135 A (BROOKES & ADAMS LTD; ARNOLD EDWIN offenbart (Seite 2, Zeile 94 - Seite 3, Zeile 85; Abbildungen 1-4) einen Türschliesser zum Einsatz in oder an einem vertikalen Türpfosten oder zum festen Aufsetzen auf einen solchen, einschliessend einen Bolzen 13, der an seinen beiden Enden in je einer Scheibe 12 gelagert ist, wobei die beiden Scheiben 12 über eine parallel zum Bolzen 13 verlaufende, von ihm radial beabstandete Brücke 10 miteinander fest verbunden sind. Der Bolzen 13 trägt in seiner Längsmitte eine Drehscheibe 23, die sich radial bis zur Innenseite der Brücke 10 erstreckt, wobei ober- und unterhalb der Drehscheibe 5 je eine Stahlfeder 9, 10 mit mehreren Windungen um den Bolzen 1 herum geführt ist. Der Türschliesser nach PCT/EP2017/068466 ist nur in eine Richtung wirksam und sein Aufbau und seine Wirkungsweise wesentlich unterschiedlich zum hier offenbarten. Der Türschliesser nach US 2 102 321 A (KEENE WILLIAM J ) weist nur eine Feder auf und diese ist nicht nicht zwischen den Scheiben (12,16) angeordnet. Der Fachmann findet darin keine Anregung für einen Türschliesser wie vorliegend konstruiert, ebenso wie auch der Türschliesser nach US 139 458 A (DAVID DICK) 3. Juni 1873 (1873-06-03) dazu Hinweise gibt.There are of course a large number of solutions in the prior art for this purpose. One possible solution is in FR 2 380 406 disclosed. It is a double-sided effective door closer, which, however, is not suitable for a garden door due to its construction. The construction is not housed in a closed housing and has many sharp corners and edges that pose a risk of injury. In addition, this door closer is designed to be visible as an open mechanism, and several individual parts are visible on it, including a spiral spring, which is probably covered by an angle iron, but is otherwise openly exposed to the weather. Since there is only a single spring, the closing force is rather modest in view of the associated dimensions. In addition, it is not possible to steplessly preload the spring. Overall, the construction is not very elegant and is probably also complex to manufacture and, above all, to cultivate. GB 395 135 A (BROOKES & ADAMS LTD; ARNOLD EDWIN discloses (page 2, line 94 - page 3, line 85; Figures 1-4) a door closer for use in or on a vertical door post or to be placed firmly on such, including a bolt 13, which is mounted at each of its two ends in a disk 12, the two disks 12 being firmly connected to one another via a radially spaced bridge 10 running parallel to the bolt 13. The bolt 13 carries a rotary disk 23 in its longitudinal center, which radial to extends to the inside of the bridge 10, with a steel spring 9, 10 each being guided around the bolt 1 with several turns above and below the turntable 5. The door closer after PCT / EP2017 / 068466 is only effective in one direction and its structure and mode of operation are significantly different from what is disclosed here. The door closer after US 2 102 321 A (KEENE WILLIAM J ) has only one spring and this is not not not arranged between the disks (12, 16). The person skilled in the art does not find any suggestion therein for a door closer as constructed in the present case, nor does the door closer according to this US 139 458 A (DAVID DICK) June 3, 1873 (1873-06-03) gives information on this.

Die Aufgabe der vorliegenden Erfindung ist es vor diesem technologischen Hintergrund, einen kompakten und soliden Türschliesser für eine Gartentür, für einen Weidezaun und ähnliche Anwendungen zu schaffen, welcher in beide Schliessrichtungen wirksam ist, der wartungsfrei ist und sich bei Neuausführungen von Türen wie auch nachträglich einfach in einen Türpfosten hinein integrieren lässt, sodass sein Antrieb unsichtbar bleibt. Auch sein Anbau soll einfach sein.Against this technological background, the object of the present invention is to create a compact and solid door closer for a garden door, for a pasture fence and similar applications, which is effective in both closing directions, which is maintenance-free and which is easy to use for new designs of doors as well as retrospectively can be integrated into a door post so that its drive remains invisible. It should also be easy to grow.

Diese Aufgabe wird gelöst von einem zweiseitig wirksamen Türschliesser zum Einsatz in oder an einem vertikalen Türpfosten oder zum festen Aufsetzen auf einen solchen, der sich durch die Merkmale des Patentanspruches 1 auszeichnet. Dieser Türschliesser ist erstens zweiseitig wirksam, zweitens ist der Bolzen drehbar in zwei Scheiben gelagert ist, wobei er aus der oberen Scheibe herausragt, zur Übertragung eines Drehmomentes auf einen Treiberstab, drittens ist eine Drehscheibe fest mit dem Bolzen verbunden ist, und in deren Umfangsbereich durchsetzt ein Mitnehmerbalken diese Drehscheibe senkrecht, sodass der Mitnehmerbalken innerhalb der Brücke oder der Stiftschrauben an dieser bzw. diesen in beiden Drehrichtungen des Bolzens vorbeischwenkbar ist. Viertens sind die beiden Stahlfedern so verbaut, dass der Bolzen aus einer mittleren, neutralen Drehlage in jeder Drehrichtung nur unter Wirkung der Federkraft der Stahlfedern auslenkbar ist. Dieser Türschliesser ist deshalb in beiden Schliessrichtungen wirksam ist und er lässt sich nachträglich einfach in einen Türpfosten hinein integrieren.This object is achieved by a double-sided effective door closer for use in or on a vertical door post or for fixed placement on one, which is characterized by the features of claim 1. This door closer is firstly two-sided effect, second is the bolt is rotatably mounted in two slices, wherein it protrudes from the upper disc, is connected to transmit torque to a drive rod, thirdly, a hub fixedly connected to the pin, and passes through in the peripheral area a driving bar this turntable vertically, so that the driving bar within the bridge or the studs can be swiveled past this or these in both directions of rotation of the bolt. Fourth , the two steel springs are installed in such a way that the bolt can only be deflected from a central, neutral rotational position in each direction of rotation under the action of the spring force of the steel springs. This door closer is therefore effective in both closing directions and it can be easily integrated into a door post afterwards.

In Figur 1 ist eine erste Variante des Türschliessers offen dargestellt, sodass der Blick ins Innere des Türschliessers freigegeben ist und man seinen konstruktiven Aufbau erkennen kann. Als Besonderheit wirkt dieser Türschliesser oder Türtreiber auf beide Seiten. Eine Tür kann also gegen aussen oder innen aufgeschwenkt werden und in beiden Fällen wird sie zuverlässig wieder in ihre Schliessposition zurückgeschwenkt. Hierzu besteht dieser Türschliesser aus einem zentralen, vertikal angeordneten Bolzen 1, der an seinen beiden Enden in je einer Scheibe 2, 3 drehbar gelagert ist, wobei er die obere Scheibe 2 durchsetzt und oben aus ihr herausragt. Von dort aus ist das von ihm aufgebrachte Drehmoment auf einen Treiberstab übertragbar. Die beiden Scheiben 2, 3 sind über eine parallel zum Bolzen 1 verlaufende, von ihm radial beabstandete Brücke 4 miteinander verbunden. Es handelt sich dabei um ein Hohlstahlsegment, das zwischen die beiden Scheiben 2, 3 in der gezeigten Art fest verbaut ist. Der drehbar gelagerte Bolzen 1 trägt in seiner Längsmitte eine mit ihm fest verbundene Drehscheibe 5, die sich bis zur hier sichtbaren Innenseite 6 der Brücke 4 erstreckt. Im Umfangsbereich 7 der Drehscheibe 5 ist sie von einem Mitnehmerbalken 8 in Form eines Flachstahls durchsetzt, welcher senkrecht bzw. axial zu ihr verläuft, sodass der Mitnehmerbalken 8 innerhalb der Brücke 4 an dieser in beiden Drehrichtungen des Bolzens 1 vorbeigeschwenkt werden kann. Oberhalb und unterhalb der Drehscheibe 5 sitzt je eine Stahlfeder 9, 10, die mit mehreren Windungen um den Bolzen 1 herum geführt ist. Je ein freies Ende 11a dieser beiden Stahlfedern 9, 10 liegt einerseits an der einen Längsseite 12 der Brücke 4 und an der einen Längsseite 13 des Mitnehmerbalkens 8 an, und das jeweils andere freie Ende 11b der Feder liegt an der gegenüberliegenden, anderen Längsseite der Brücke 4 und des Mitnehmerbalkens 8 an, was in der Figur 1 allerdings nicht direkt sichtbar ist. Diese jenseitigen Enden 11bder Federn 9, 10 an diesen Stellen auf der im Bild hinteren Seite sind aber mit gestrichelten Linien angedeutet. Durch diese Anordnung der Stahlfedern 9, 10 und den auf beide Seiten schwenkbaren Mitnehmerbalken 8 kann der Bolzen 1 auf beide Seiten nur gegen Federkraft ausschwenken und wird in beiden Fällen von den Enden 11a, oder 11b der Stahlfedern 9, 10, mit jeder Auslenkung gespannt und daher zurück in seine neutrale Mittelstellung getrieben.In Figure 1 a first variant of the door closer is shown open, so that a view of the inside of the door closer is released and its structural design can be seen. As a special feature, this door closer or door driver works on both sides. A door can therefore be swung open towards the outside or inside and in both cases it is reliably swiveled back into its closed position. For this purpose, this door closer consists of a central, vertically arranged bolt 1, which is rotatably mounted at both ends in a disk 2, 3, whereby it penetrates the upper disk 2 and protrudes from it at the top. From there, the torque it applies can be transferred to a driver rod. The two disks 2, 3 are connected to one another via a bridge 4 which runs parallel to the bolt 1 and is radially spaced apart from it. It is a hollow steel segment that is permanently installed between the two disks 2, 3 in the manner shown. The rotatably mounted bolt 1 carries in its longitudinal center a turntable 5 firmly connected to it, which extends as far as the inside 6 of the bridge 4, which is visible here. In the circumferential area 7 of the turntable 5, it is penetrated by a driving beam 8 in the form of a flat steel, which runs perpendicular or axially to it, so that the driving beam 8 within the bridge 4 in both of these Directions of rotation of the bolt 1 can be pivoted past. A steel spring 9, 10 is seated above and below the turntable 5 and is guided around the bolt 1 with several turns. One free end 11a of each of these two steel springs 9, 10 rests on one side 12 of the bridge 4 and on one side 13 of the driver bar 8, and the other free end 11b of the spring is on the opposite, other longitudinal side of the bridge 4 and the driver bar 8 to what is in the Figure 1 however, is not directly visible. These opposite ends 11b of the springs 9, 10 at these points on the rear side in the figure are indicated with dashed lines. Due to this arrangement of the steel springs 9, 10 and the driver bar 8, which can be pivoted on both sides, the bolt 1 can only pivot out against spring force on both sides and is tensioned in both cases by the ends 11a or 11b of the steel springs 9, 10 with every deflection therefore driven back to its neutral center position.

Der aus der einen Scheibe 2 oben herausragende Bolzen 1 bildet mit seinem Ende 14 den einen Teil eines Kreuzgelenkes 15, während ein zweiter Teil 16 dieses Kreuzgelenkes 15 auf der dem Gelenk 15 abgewandten Seite eine Büchse 17 mit einem Innengewinde 18 zum Einschrauben eines Treiberstabes bildet. Als Variante kann der zweite Teil 16 des Kreuzgelenkes 15 auf der dem Gelenk 15 abgewandten Seite einen Stab mit endseitigem Aussengewinde bilden, auf welches ein Treiberstab mit endseitiger Gewindemuffe aufschraubbar ist. Anstelle einer Gewindeverbindung kann auch eine Steckverbindung dienen, zum Beispiel mit einem Bajonett-Verschluss. Statt eines Kreuzgelenkes kann am Ende 14 des herausragenden Bolzens 1 ein Zapfen mit Querbohrung aufgesetzt und mit einem Schwerspannstift gesichert werden. In die Querbohrung lässt sich dann eine Rute einfügen und mit einer axialen Schraube festklemmen. Auf diese Weise erhält man neben dem Türschliesser für Gartentore auch einen Türschliesser für Schliessruten in Weidezaunöffnungen.The bolt 1 protruding from the top of one disk 2 forms with its end 14 part of a universal joint 15, while a second part 16 of this universal joint 15 forms a bushing 17 with an internal thread 18 for screwing in a driver rod on the side facing away from the joint 15. As a variant, the second part 16 of the universal joint 15 on the side facing away from the joint 15 can form a rod with an external thread at the end, onto which a driver rod with a threaded sleeve at the end can be screwed. Instead of a threaded connection, a plug connection can also be used, for example with a bayonet lock. Instead of a universal joint, a pin with a transverse bore can be placed on the end 14 of the protruding bolt 1 and secured with a dowel pin. A rod can then be inserted into the transverse bore and clamped with an axial screw. In this way, in addition to the door closer for garden gates, you also get a door closer for closing rods in pasture fence openings.

Die endseitigen Scheiben 2, 3 sind vorzugsweise kreisrunde Scheiben, die in einen Rohrabschnitt 19 einpassen, der hier zur Hälfte aufgeschnitten dargestellt ist. Der Rohrabschnitt 19 ist an jedem Ende mit einer weiteren Abdeckscheibe 20, 21 ausgerüstet, deren Umfänge den Rohrabschnitt 19 ganz oder teilweise überragen, unter Einschluss der beiden kreisrunden Scheiben 2, 3. Die Abdeckscheibe 20 ist mit der endseitigen Scheibe 2 fest verbunden, sodass sich jene nicht gegenüber der Brücke 4 und den endseitigen Scheiben 2, 3 verdrehen kann. Mit den beiden Abdeckscheiben 20, 21 und dem zwischenliegenden Rohrabschnitt 19 aus Stahl oder Kunststoff wird der Antrieb des Türschliesser vollständig und uneinsehbar eingeschlossen, es sei denn, der Rohrabschnitt 19 wird von einem Abschnitt eines durchsichtigen Plexiglas-Rohres gebildet. Der Rohrabschnitt 19 wird, um verdrehsicher gegenüber den Abdeckscheiben 20, 21 zu sein, noch mit radialen Schrauben 29 an diese gespannt und gesichert.The end disks 2, 3 are preferably circular disks which fit into a pipe section 19, which is shown cut open in half here. The pipe section 19 is equipped at each end with a further cover disk 20, 21, the circumference of which protrudes completely or partially beyond the pipe section 19, including the two circular disks 2, 3. The cover disk 20 is firmly connected to the end disk 2 so that that cannot rotate with respect to the bridge 4 and the disks 2, 3 at the end. With the two cover disks 20, 21 and the intermediate pipe section 19 made of steel or Plastic, the drive of the door closer is completely and securely enclosed, unless the pipe section 19 is formed by a section of a transparent Plexiglas pipe. In order to be secure against rotation with respect to the cover disks 20, 21, the pipe section 19 is also tensioned and secured to the cover disks 29 with radial screws 29.

Die Figur 2 zeigt den Türschliesser schematisch dargestellt, eingebaut in einen Türpfosten, mit seinem Treiberstab 27 und dem Türrahmen 28. Der Türschliesser wird von oben in das Stahlrohr 25 eines Türpfostens eingefügt. Hierfür wird zunächst eine Muffe 22 über das obere Ende des Stahlrohrs 25 gestülpt. Dann wird der Türschliesser durch die Muffe hindurch in das Stahlrohr 25 eingesetzt und liegt dann mit dem auskragenden Rand seiner oberen Scheibe 20 auf der Muffe 22 auf, sodass die Scheibe 20 und Muffe 22 aussen bündig abschliessen. Die Muffe 22 wird mittels mehrerer Madenschrauben 26, welche sie radial durchsetzen, am Stahlrohr 25 verspannt und ist hernach gegenüber dem Stahlrohr 25 verdrehsicher verbaut. Die Scheibe 20 lässt sich ebenfalls mittels mehrerer Madenschrauben 29 verdrehsicher auf der Muffe 22 verspannen. Der oben aus der Scheibe 20 herausragende Abschnitt 14 des Bolzens 1 ist dann über das Kreuzgelenk 15 drehfest und gelenkig mit dem Treiberstab 27 verbindbar, der am anderen Ende mit einem zu treibenden oder zu schliessenden Türrahmen 28 verbunden werden kann. Bei dieser Verbindung kann der Treiberstab 27 mit seinem Endabschnitt in der Fassung 30 in axialer Richtung hin und her schieben. Die Fassung 30 ist schwenkbar um die Achse 31 in der Halterung 32 gelagert. Die Halterung 32 ist wiederum schwenkbar um den Schaft 33 einer Rohrschelle 34 gelagert.The Figure 2 shows the door closer shown schematically, installed in a door post, with its driver rod 27 and the door frame 28. The door closer is inserted from above into the steel tube 25 of a door post. For this purpose, a sleeve 22 is first placed over the upper end of the steel pipe 25. Then the door closer is inserted through the sleeve into the steel tube 25 and then rests with the protruding edge of its upper disc 20 on the sleeve 22 so that the disc 20 and sleeve 22 are flush on the outside. The sleeve 22 is braced on the steel pipe 25 by means of a plurality of grub screws 26 which penetrate it radially and is then installed so that it cannot rotate relative to the steel pipe 25. The disk 20 can also be clamped on the sleeve 22 in a manner secure against rotation by means of a plurality of grub screws 29. The section 14 of the bolt 1 protruding from the disk 20 can then be connected in a rotationally fixed and articulated manner via the universal joint 15 to the driver rod 27, which can be connected at the other end to a door frame 28 to be driven or closed. With this connection, the end section of the driver rod 27 can slide back and forth in the mount 30 in the axial direction. The mount 30 is mounted in the holder 32 such that it can pivot about the axis 31. The holder 32 is in turn mounted pivotably about the shaft 33 of a pipe clamp 34.

In Figur 3 ist dieser Türschliesser von schräg oben dargestellt, fertig zum Einbau in den oberen Abschnitt eines Türpfostens. Er steckt in einem Rohrabschnitt 19. Das kann ein Edelstahl-Rohrabschnitt sein oder auch Rohrabschnitt aus Plexiglas, um den Blick auf die innere Mechanik freizugeben.In Figure 3 This door closer is shown obliquely from above, ready for installation in the upper section of a door post. It is located in a pipe section 19. This can be a stainless steel pipe section or a pipe section made of Plexiglas to reveal the internal mechanics.

In Figur 4 ist ein weiter entwickelter Türschliesser offen dargestellt, sodass der Blick ins Innere des Türschliessers freigegeben ist und man seinen konstruktiven Aufbau erkennen kann. Auch dieser Türschliesser oder Türtreiber wirkt auf beide Seiten. Hierzu besteht dieser Türschliesser wiederum aus einem zentralen, vertikal angeordneten Bolzen 1, der an seinen beiden Enden in je einer Scheibe 2, 3 drehbar gelagert ist, wobei er die obere Scheibe 2 durchsetzt und aus ihr herausragt. Von dort aus ist das von ihm aufgebrachte Drehmoment auf einen Treiberstab übertragbar. Die beiden Scheiben 2, 3 sind über parallel zum Bolzen 1 verlaufende, von ihm radial beabstandete Stiftschrauben 4a, 4b und 4c miteinander verbunden. Es handelt sich dabei um Stahlstifte, die an den Enden jeweils ein Gewinde aufweisen. Dabei ist jeweils ein Gewinde in der Scheibe 2 eingelassen und das andere durchsetzt die Scheibe 3. Zwischen den Scheiben 2 und 3 befindet sich zudem ein Rohrabschnitt 19, der die Schliessmechanik schützt und ihr Stabilität verleiht. Auf die Gewinde, die durch die Scheibe 3 führen, werden Hutmuttern festgeschraubt, derart dass die Scheiben 2 und 3 sowie der zwischenliegende Rohrabschnitt 19 fest miteinander verbunden sind. Die Stiftschraube 4c dient einerseits als Endanschlag für die ausdrehenden Federenden und andererseits zur gleichmässigen Verschraubung des Schliesszylinders. Der drehbar gelagerte Bolzen 1 trägt in seiner Längsmitte einen mit ihm fest verbundenen Drehkörper 5, der sich bis zur hier sichtbaren Innenseite 6 der Stiftschrauben 4a, 4b erstreckt. Im Umfangsbereich 7 des Drehkörpers 5 ist sie von einem Mitnehmerbalken 8 in Form eines Flachstahls durchsetzt, welcher senkrecht bzw. axial zu ihm verläuft, sodass der Mitnehmerbalken 8 innerhalb der beiden Stiftschrauben 4a, 4b an diesen in beiden Drehrichtungen des Bolzens 1 vorbeigeschwenkt werden kann. Oberhalb und unterhalb der Drehscheibe 5 sitzt je eine Stahlfeder 9, 10, die mit mehreren Windungen um den Bolzen 1 herum geführt ist. Je ein freies Ende 11a dieser beiden Stahlfedern 9, 10 liegt an der Stiftschraube 4a und an der einen Längsseite 13a des Mitnehmerbalkens 8 an, und das jeweils andere freie Ende 11b der Feder liegt an der Stiftschraube 4b und an der gegenüberliegenden, in der Figur nicht sichtbaren Längsseite 13b des Mitnehmerbalkens 8 an. Diese jenseitigen Enden 11b der Federn 9, 10 an diesen Stellen auf der im Bild hinteren Seite sind aber mit gestrichelten Linien angedeutet. Durch diese Anordnung der Stahlfedern 9, 10 und den auf beide Seiten schwenkbaren Mitnehmerbalken 8 kann der Bolzen 1 auf beide Seiten nur gegen Federkraft ausschwenken und wird in beiden Fällen von den Enden 11a oder 11b der Stahlfedern 9, 10 mit jeder Auslenkung gespannt und daher zurück in seine neutrale Mittelstellung getrieben.In Figure 4 a further developed door closer is shown open so that a view into the interior of the door closer is released and its structural design can be seen. This door closer or door driver also acts on both sides. For this purpose, this door closer consists in turn of a central, vertically arranged bolt 1, which is rotatably mounted at each of its two ends in a disk 2, 3, whereby it penetrates the upper disk 2 and protrudes from it. From there the torque applied by it can be transferred to a driver rod. The two disks 2, 3 are connected to one another via stud bolts 4a, 4b and 4c which run parallel to the bolt 1 and are radially spaced apart from it. These are steel pins that each have a thread at the ends. In each case one thread is embedded in the disk 2 and the other penetrates the disk 3. Between the disks 2 and 3 there is also a pipe section 19 which protects the locking mechanism and gives it stability. Cap nuts are screwed tightly onto the threads that lead through the washer 3, so that the washers 2 and 3 and the pipe section 19 between them are firmly connected to one another. The stud screw 4c serves on the one hand as an end stop for the unscrewing spring ends and on the other hand for evenly screwing the lock cylinder. The rotatably mounted bolt 1 carries in its longitudinal center a rotating body 5 which is firmly connected to it and which extends as far as the inside 6 of the studs 4a, 4b which is visible here. In the circumferential area 7 of the rotating body 5, it is penetrated by a driving bar 8 in the form of a flat steel, which runs perpendicular or axially to it, so that the driving bar 8 can be pivoted past the two studs 4a, 4b in both directions of rotation of the bolt 1. A steel spring 9, 10 is seated above and below the turntable 5 and is guided around the bolt 1 with several turns. One free end 11a of each of these two steel springs 9, 10 rests on the stud 4a and on one longitudinal side 13a of the driver bar 8, and the other free end 11b of the spring rests on the stud 4b and on the opposite one, not in the figure visible longitudinal side 13b of the driver bar 8. These opposite ends 11b of the springs 9, 10 at these points on the rear side in the figure are indicated with dashed lines. Due to this arrangement of the steel springs 9, 10 and the drive bar 8 which can be pivoted on both sides, the bolt 1 can only swing out against spring force on both sides and is tensioned in both cases by the ends 11a or 11b of the steel springs 9, 10 with every deflection and therefore back driven into its neutral middle position.

Der aus der Scheibe 2 herausragende Bolzen 1 bildet mit seinem Ende 14 den einen Teil eines Kreuzgelenkes 15, während ein zweiter Teil 16 dieses Kreuzgelenkes 15 auf der dem Gelenk 15 abgewandten Seite eine Büchse 17 mit einem Innengewinde 18 zum Einschrauben eines Treiberstabes bildet. Als Variante kann der zweite Teil 16 des Kreuzgelenkes 15 auf der dem Gelenk 15 abgewandten Seite einen Stab mit endseitigem Aussengewinde bilden, auf welches ein Treiberstab mit endseitiger Gewindemuffe aufschraubbar ist. Anstelle einer Gewindeverbindung kann auch eine Steckverbindung dienen, zum Beispiel mit einem Bajonett-Verschluss. Statt eines Kreuzgelenkes kann am Ende 14 des herausragenden Bolzens 1 ein Zapfen mit Querbohrung aufgesetzt und mit einem Schwerspannstift gesichert werden. In die Querbohrung lässt sich dann eine Rute einfügen und mit einer axialen Schraube festklemmen. Auf diese Weise erhält man neben dem Türschliesser für Gartentore auch einen für Schliessruten von Weidezaunöffnungen.The bolt 1 protruding from the disk 2 forms with its end 14 part of a universal joint 15, while a second part 16 of this universal joint 15 forms a bushing 17 with an internal thread 18 for screwing in a driver rod on the side facing away from the joint 15. As a variant, the second part 16 of the universal joint 15 on the side facing away from the joint 15 form a rod with an external thread at the end, onto which a driver rod with a threaded sleeve at the end can be screwed. Instead of a threaded connection, a plug connection can also be used, for example with a bayonet lock. Instead of a universal joint, a pin with a transverse bore can be placed on the end 14 of the protruding bolt 1 and secured with a dowel pin. A rod can then be inserted into the transverse bore and clamped with an axial screw. In this way, in addition to the door closer for garden gates, you also get one for closing rods of pasture fence openings.

Die Figur 5 zeigt den Türschliesser vor dem Einsetzen in eine Ringfassung 36 oder als Variante in eine Rohrschelle oder einen Rohrabschnitt an einem Türpfosten, welcher in Verlaufrichtung eines Zaunes auf die Innenseite des Türpfostens 35 montiert wird, vom Durchgang aus gesehen dargestellt. In diese Ringfassung wird der Türschliesser verdrehsichert eingesetzt. Die Figur 6 zeigt ihn dann eingesetzt in die Ringfassung 36 an einem Zaunpfosten 35. Oben ist eine Schliessrute 39 anstelle einer Treiberstange in das Bolzenende 14 des Türschliessers eingesteckt und gesichert. Der Zaun ist dann zu Fuss oder auch mit einem Fahrzeug passierbar, indem die Schliessrute 39 von der durchschreitenden Person oder dem langsam durchfahrenden Fahrzeug aufgeschwenkt wird und nach dem Passieren zuverlässig wieder geschlossen wird. Tiere hingegen nehmen die Schliessrute 39 als Hindernis wahr.The Figure 5 shows the door closer before being inserted into a ring mount 36 or as a variant in a pipe clamp or a pipe section on a door post, which is mounted on the inside of the door post 35 in the direction of a fence, viewed from the passage. The door closer is inserted into this ring socket so that it cannot twist. The Figure 6 shows it then inserted into the ring socket 36 on a fence post 35. At the top, a locking rod 39 is inserted and secured in the bolt end 14 of the door closer instead of a driver rod. The fence can then be passed on foot or with a vehicle in that the closing rod 39 is swung open by the person walking through or the vehicle driving slowly through and is reliably closed again after passing. Animals, however, perceive the closing rod 39 as an obstacle.

Die Figur 7 zeigt den Türschliesser im Inneren des Stahlrohrs 25 eines Türpfostens eingesetzt, zum Einsatz als Türschliesser für ein Gartentor, wie schon mit Figur 2 in schematischer Weise gezeigt wurde. Ein Haltebügel 34 ist Teil einer Halterung 32, durch welche der Treiberstab 27 hindurchgeführt ist und wegen der unterschiedlichen Positionen der Türschwenkachse und der Schwenkachse des Türschliesser-Bolzens in der Halterung 32 hin und her verschiebbar ist.The Figure 7 shows the door closer used inside the steel tube 25 of a door post, for use as a door closer for a garden gate, as with Figure 2 has been shown in a schematic manner. A retaining bracket 34 is part of a bracket 32 through which the driver rod 27 is passed and can be moved back and forth in the bracket 32 because of the different positions of the door pivot axis and the pivot axis of the door closer bolt.
