Description

Die Erfindung bezieht sich auf einen Außenschwingtürverschluß für Omnibusse.The invention relates to an external swing door lock for buses.

Ein Verschluß, insbesondere für Außenschwingtüren von Omnibussen, ist durch die DE-A- 39 29 324 bekanntgeworden. Dieser bekannte Verschluß besteht aus einem an einer Tür zu befestigenden Gehäuse, das einen Außen- und einen Innengriffkörper sowie einen mit diesen in Eingriff stehenden Mitnehmer für ein Entriegeln und Verriegeln der Tür bewirkenden Zugstangen in drehbeweglicher Anordnung lagert. Dabei steht der Außengriffkörper mit dem Mitnehmer im Sinne einer Verriegelungs- und Entriegelungsbewegung und der Innengriffkörper mit dem Mitnehmer ausschließlich im Sinne einer Entriegelungsbewegung in Eingriff. Der Außengriffkörper ist mit einem Zylinderschloß ausgerüstet, mit dem die Drehbeweglichkeit des Außengriffkörpers blockiert werden kann.A closure, in particular for swing doors of buses, has become known from DE-A-39 29 324. This known closure consists of a housing to be fastened to a door, which supports an outer and an inner handle body as well as an engaging driver for unlocking and locking the door pull rods in a rotatable arrangement. The outer handle body engages with the driver in the sense of a locking and unlocking movement and the inner handle body with the driver only in the sense of an unlocking movement. The outer handle body is equipped with a cylinder lock, with which the mobility of the outer handle body can be blocked.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Außenschwingtürverschluß für Omnibusse zu schaffen, der aus nur wenigen Einzelteilen besteht und einen besonders einfachen und dennoch robusten Aufbau aufweist.The present invention has for its object to provide an outer swing door lock for buses, which consists of only a few items and has a particularly simple, yet robust structure.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß der Außenschwingtürverschluß businnenseitig an der Tür anordbar ist und im wesentlichen aus einem zylindrischen Gehäuse mit daran einendig sitzender Befestigungsplatte, einem drehbeweglich am Gehäuse gelagerten Mitnehmer für Verriegelungsstangen, die mit ihren freien Enden in einander gegenüberliegenden Rastaufnahmen des Türrahmens einschiebbar und herausziehbar sind, einem drehfest mit dem Mitnehmer verbundenen Griffkörper, einem den Griffkörper durchsetzenden und in einer Bohrung des Mitnehmers verdrehfest aufgenommenen Zylinderschloß und einem über einen Schlüssel des Zylinderschlosses gegen die Kraft von Federmitteln zu betätigenden Schnäpper besteht, wobei der Schnäpper sich in entriegelter Stellung der Verriegelungsstangen stets in einer ein Verdrehen des Griffkörpers blockierenden Raststellung befindet, so daß ein Verriegeln der Tür nur mit Schlüssel ein Entriegeln hingegen ohne Schlüssel erfolgen kann.To solve this problem it is provided according to the invention that the outer swing door lock can be arranged on the inside of the bus on the door and essentially consists of a cylindrical housing with a mounting plate attached to it at one end, a rotatably mounted driver for locking rods, the free ends of which lie in mutually opposite latching receptacles of the door frame are insertable and extractable, a handle body connected to the driver in a rotationally fixed manner, a cylinder lock passing through the handle body and received in a bore of the driver in a rotationally fixed manner, and a catch which can be actuated by means of a key of the cylinder lock against the force of spring means, the catch being in the unlocked position the locking rods are always in a locking position blocking a turning of the handle body, so that locking the door with a key only unlocks it without a key can olgen.

Die erfindungsgemäße Ausbildung des Außenschwingtürverschlusses macht ein Durchbohren der Außenschwingtür und damit auch die Anordnung türaußenseitiger Abdichtungsmittel entbehrlich. Das Zylinderschloß ist businnenseitig angeordnet und somit bestens gegen Witterungseinflüsse geschützt. Besonders vorteilhaft ist der aus nur wenigen Teilen bestehende Grundaufbau des Außenschwingtürverschlusses der sehr robust ist und den technischen Anforderungen vollauf genügt. Der erfindungsgemäße Außenschwingtürverschluß ermöglicht es, eine Außenschwingtür bei Stillstandzeiten eines Busses von innen zu verriegeln und von innen auch wieder zu entriegeln. Eine Verriegelung ist dabei nur unter Zuhilfenahme eines Schlüssels möglich, mittels dem der Schnäpper aus seiner Raststellung herausbewegt werden kann. Erst hiernach ist es möglich, den Griffkörper nebst Mitnehmer zu drehen und die Verriegelungsstangen in die Widerlager auszufahren. Eine Verriegelung der Außenschwingtüren von Bussen wird verlangt, um es z.B. auch bei Ausfall des Druckluftsystems, mit dem die Bustüren üblicherweise geöffnet und geschlossen werden, unmöglich zu machen, die Außenschwingtüren von außen zu öffnen. Der erfindungsgemäße Außenschwingtürverschluß macht also die Außenschwingtüren von Omnibussen einbruchssicher. Des weiteren wird verlangt, daß eine, z.B. irrtümlich in einem Omnibus eingeschlossene Person den Bus auch bei verriegelter Außenschwingtür jederzeit verlassen kann. Dieser Forderung wird die Erfindung vollauf gerecht, denn der Griffkörper läßt sich jederzeit und ohne Schlüssel unter Mitnahme der Verriegelungsstangen in Entriegelungsrichtung betätigen. Der erfindungsgemäße Außenschwingtürverschluß ermöglicht somit eine problemlose Verriegelung (mit Schlüssel) und eine problemlose (Not-) Entriegelung (ohne Schlüssel).The design of the outer swing door lock according to the invention makes it unnecessary to drill through the outer swing door and thus also to dispose the sealing means on the outside of the door. The cylinder lock is arranged on the inside of the bus and thus optimally protected against the weather. The basic structure of the swing door lock, which consists of only a few parts, is particularly advantageous because it is very robust and fully meets the technical requirements. The outer swing door lock according to the invention makes it possible to lock an outer swing door from the inside when a bus is at a standstill and also to unlock it again from the inside. Locking is only possible with the help of a key, by means of which the catch can be moved out of its locked position. Only then is it possible to turn the handle body and driver and to extend the locking rods into the abutments. Locking of the outside swing doors of buses is required, for example to make it impossible to open the outside swing doors even if the compressed air system, with which the bus doors are usually opened and closed, fails. The outer swing door lock according to the invention thus makes the outer swing doors of omnibuses burglar-proof. Furthermore, it is required that a person, for example, accidentally trapped in a bus, takes the bus even when the outer swing door is locked can leave at any time. The invention fully meets this requirement because the handle body can be actuated at any time and without a key while taking the locking rods in the unlocking direction. The external swing door lock according to the invention thus enables problem-free locking (with key) and problem-free (emergency) unlocking (without key).

Eine Ausgestaltung der Erfindung sieht vor, daß der Schnäpper verschiebbar in einer den Mitnehmer querenden Öffnung angeordnet ist und mit seinem freien, den Federmitteln abgewandten Ende in einer radialen Schlitzöffnung des Gehäuses sitzt, wenn sich die Verriegelungsstangen in ihrer aus den Rastausnehmungen des Türrahmens herausgezogenen Entriegelungslage befinden. Der Schnäpper muß damit zunächst aus der Schlitzöffnung des Gehäuses herausbewegt werden, bevor es möglich ist, eine Verriegelung der Außenschwingtür vorzunehmen.An embodiment of the invention provides that the catch is slidably arranged in an opening crossing the driver and sits with its free end facing away from the spring means in a radial slot opening of the housing when the locking rods are in their unlocked position pulled out of the locking recesses in the door frame . The catch must therefore first be moved out of the slot opening in the housing before it is possible to lock the outer swing door.

Für eine Schnäpperbetätigung ist am Zylinderschloß ein Exzenterzapfen in axialer Richtung überstehend angeordnet, der in eine Mitnahmeöffnung des Schnäppers eingreift. Der Exzenterzapfen ist Teil des Zylinderschlosses und daher nur mit Schlüssel betätigbar. Es kann daher nicht zu einer Fehlfunktion, also nicht zur unbeabsichtigten Türverriegelung kommen, denn eine Türverriegelung ist vom Einsatz des zugehörigen Schlüssels abhängig.For actuation of the catch, an eccentric pin projecting in the axial direction is arranged on the cylinder lock, which engages in a driving opening of the catch. The eccentric pin is part of the cylinder lock and can therefore only be operated with a key. This means that there can be no malfunction, i.e. inadvertent door locking, because door locking depends on the use of the associated key.

Eine Weiterbildung der Erfindung kann darin bestehen, daß der Mitnehmer mit einem, den freien Endbereich des Gehäuses über einen axialen Längenbereich aufnehmenden Ringspalt ausgebildet ist. Damit ergibt sich für den Mitnehmer, der im übrigen schraubgemäß am Gehäuse drehbar festgelegt ist, eine saubere und wackelfreie Führung.A further development of the invention can consist in that the driver is formed with an annular gap which receives the free end region of the housing over an axial length region. This results in a clean and wobble-free guidance for the driver, which is rotatably attached to the housing according to the screw.

Gemäß einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß der Mitnehmer eine radiale Bohrung mit einer darin einendig abgestützten Schraubenfeder aufweist, die anderendig eine Rastkugel belastet, welche in um 90 Winkelgrade zueinander versetzte Rastausnehmungen am Gehäusemantel einzurasten vermag. Damit ergibt sich eine zuverlässig wirkende Arretierung für den Griffkörper in den zwei Endstellungen, bei denen die Verriegelung einmal geöffnet und einmal geschlossen ist.According to a further embodiment of the invention, it is provided that the driver has a radial bore with a helical spring supported therein at one end, which at the other end loads a locking ball, which is able to snap into the recesses on the housing shell offset by 90 degrees to one another. This results in a reliably acting locking for the handle body in the two end positions, in which the lock is opened and closed once.

Es kann weiterhin vorgesehen sein, daß das Zylinderschloß durch eine, eine radiale Bohrung des Mitnehmerschafts durchsetzende Schraube am Mitnehmer befestigt ist. Diese Maßnahme bietet die Möglichkeit, ein defektes Schloß ersetzen zu können ohne den gesamten Verschluß auswechseln zu müssen.It can further be provided that the cylinder lock is fastened to the driver by a screw which penetrates a radial bore of the driver shaft. This measure offers the possibility of being able to replace a defective lock without having to replace the entire lock.

Gemäß einer anderen Ausgestaltung der Erfindung, kann an der Befestigungsplatte ein Endschalter mit Tastfühler sitzen, der über einen am Mitnehmer angeordneten Steuernocken betätigbar ist. Hierdurch kann in Verbindung mit der Fahrzeugelektrik dem Fahrer akustisch oder optisch mitgeteilt werden, ob sich die Verriegelung der Außenschwingtür (Mitteltür) in verriegelter oder entriegelter Stellung befindet. Gegebenenfalls kann über den Endschalter auch die Öffnungsmechanik für die Außenschwingtür blockiert werden.According to another embodiment of the invention, a limit switch with a touch sensor can be seated on the fastening plate and can be actuated via a control cam arranged on the driver. In this way, in conjunction with the vehicle electrics, the driver can be informed acoustically or optically whether the locking of the outer swing door (center door) is in the locked or unlocked position. If necessary, the opening mechanism for the outer swing door can also be blocked using the limit switch.

Der Schnäpper ist zweckmäßigerweise in Form einer rechteckigen Platte mit abgerundeten Längsenden ausgebildet und weist zudem seitliche Ausnehmungen für die Aufnahme von Schraubendruckfedern auf.The catch is expediently designed in the form of a rectangular plate with rounded longitudinal ends and also has lateral recesses for receiving helical compression springs.

Finally, the housing 1 is formed on the outside with a stop cam 11 which, starting from the fastening plate 6, extends over an axial partial region of the housing shaft.

Der Mitnehmer 2 ist rohrförmig und einendig mit einem Mitnehmerflansch 12 ausgebildet. Bohrungen 13 im Mitnehmerflansch 12 dienen der Befestigungsanordnung von Verriegelungsstangen 14, die mit ihren freien Enden in nicht gezeigte Widerlager eines ebenfalls nicht gezeigten Türrahmens durch eine Drehbewegung des Mitnehmers 2 eingeschoben werden können. Der Mitnehmer 2 ist drehbeweglich am Gehäuse 1 angeordnet. Hierfür ist der Mitnehmer 2 unter Bildung eines Ringspalts 15 über einen axialen Längenbereich doppelwandig ausgebildet und unterendig mit einem Boden 16 versehen, an den sich ein zylindrischer Fortsatz 17 in axialer Verlängerung anschließt. Im zusammengebauten Zustand des Verschlusses greift das Gehäuse 1 mit dem freien Endbereich des Gehäuseschaftes in den Ringspalt 15 des Mitnehmers 2 ein, der sich seinerseits mit dem Boden 16 auf der Bodenplatte 8 des Gehäuses 1 abstützt, wobei der Fortsatz 17 die Bohrung 9 der Bodenplatte 8 durchsetzt. Eine Gewindebohrung im Fortsatz 17 nimmt eine Schraube 18 zur Festlegung des Mitnehmers 2 am Gehäuse 1 auf. Am freien Ende trägt der Mitnehmer 2 den Griffkörper 3 über klipsartig verrastende Befestigungselemente 19 in drehfester Anordnung.The driver 2 is tubular and has one end with a driver flange 12. Bores 13 in the driver flange 12 serve for the fastening arrangement of locking rods 14, which can be inserted with their free ends into abutments, not shown, of a door frame, also not shown, by a rotary movement of the driver 2. The driver 2 is rotatably arranged on the housing 1. For this purpose, the driver 2 is double-walled to form an annular gap 15 over an axial length range and provided with a bottom 16 at the bottom, to which a cylindrical extension 17 adjoins in an axial extension. In the assembled state of the closure, the housing 1 engages with the free end region of the housing shaft in the annular gap 15 of the driver 2, which in turn is supported with the base 16 on the base plate 8 of the housing 1, the extension 17 the bore 9 of the base plate 8 enforced. A threaded bore in the extension 17 receives a screw 18 for fixing the driver 2 on the housing 1. At the free end, the driver 2 carries the handle body 3 in a non-rotatable arrangement via clip-like fastening elements 19.

Das Zylinderschloß 4 durchsetzt eine zentrische Bohrung des Griffkörpers 3 und ist in einer stufenförmig abgesetzten Aufnahmebohrung 20 des Mitnehmers 2 befestigt. Zur auswechselbaren Befestigung des Zylinderschlosses 4 ist eine Madenschraube 21 vorgesehen, die in einer Gewindebohrung des Mitnehmers 2 sitzt. Ein Exzenterzapfen 22 ist am Zylinderschloß 4 in axialer Richtung überstehend angeordnet, der mittels Zylinderschloßschlüssel 23 verschwenkbar ist. Der Schlüssel 23 dient zum Verschwenken des Exzenterzapfen 22 in Richtung des Pfeils in Fig. 4 und damit zum Entriegeln des Schnäppers 5, der im verriegelten Zustand mit einem Endbereich in der Schlitzöffnung 10 des Gehäuses 1 sitzt und in dieser Stellung durch Schraubendruckfedern 24 gehalten ist. Der Schnäpper 5 besteht aus einer rechteckigen Platte mit abgerundeten Längsenden. In einer Breitseite weist der Schnäpper 5 eine Mitnahme-öffnung 25 für den Exzenterzapfen 22 auf und an den Längsseiten sind Ausnehmungen 26 für die Aufnahme der Schraubendruckfedern 24 vorgesehen. Der Schnäpper 5 ist verschiebbar in einer den Mitnehmer 2 querenden Öffnung 27 angeordnet und einendig durch die sich an Mitnehmervorsprüngen 28 abstützenden Schraubendruckfeder 24 belastet.The cylinder lock 4 passes through a central bore of the handle body 3 and is fastened in a stepped receiving bore 20 of the driver 2. For the interchangeable fastening of the cylinder lock 4, a grub screw 21 is provided, which is seated in a threaded bore of the driver 2. An eccentric pin 22 is arranged on the cylinder lock 4 projecting in the axial direction, which can be pivoted by means of the cylinder lock key 23. The key 23 is used to pivot the eccentric pin 22 in the direction of the arrow in FIG. 4 and thus to unlock the catch 5, which in the locked state is seated with an end region in the slot opening 10 of the housing 1 and is held in this position by helical compression springs 24. The catch 5 consists of a rectangular plate with rounded Longitudinal ends. On a broad side, the catch 5 has a driving opening 25 for the eccentric pin 22 and recesses 26 are provided on the long sides for receiving the helical compression springs 24. The catch 5 is displaceably arranged in an opening 27 crossing the driver 2 and is loaded at one end by the helical compression spring 24 which is supported on driver projections 28.

In Fig. 1, 2 und 5 ist der neue Außenschwingtürverschluß in der Türverriegelungssituation dargestellt, wobei die Verriegelungsstangen 14 in den Widerlagern des Türrahmens eingefahren sind. Zum Entriegeln der Tür braucht lediglich der Griffkörper 3 um 90 Grad gedreht zu werden, wobei der Mitnehmer 2 in Pfeilrichtung P mitschwenkt und die Verriegelungsstangen 14 aus den Widerlagern herausgezogen werden. Da der Schnäpper 5 frei drehbar im Gehäuseschaft sitzt, ist zum Lösen der Türverriegelung die Zuhilfenahme eines Schlüssels nicht erforderlich.1, 2 and 5, the new outer swing door lock is shown in the door locking situation, the locking rods 14 being retracted into the abutments of the door frame. To unlock the door, only the handle body 3 needs to be rotated by 90 degrees, the driver 2 also pivoting in the direction of the arrow P and the locking rods 14 being pulled out of the abutments. Since the catch 5 is freely rotatable in the housing shaft, the aid of a key is not required to release the door lock.

Bei entriegelter Tür nehmen der Mitnehmerflansch 12 und der Schnäpper 5 die in Fig. 3 und 4 gezeigte Stellung ein. Dabei sitzt der Schnäpper 5 zufolge der auf ihn wirkenden Federkraft mit seinem freien Ende in der Schlitzöffnung 10 des Gehäuses 1. Die Stellung des Schnäppers 5 nach Fig. 3 und 4 bedeutet, daß die Tür entriegelt, der Schnäpper 5 hingegen verriegelt ist. Eine Betätigung des Griffkörpers 3 ist somit erst möglich, wenn unter Zuhilfenahme des Schlüssels 23 der Schnäpper 5 aus der Schlitzöffnung 10 bewegt worden ist.When the door is unlocked, the driving flange 12 and the catch 5 assume the position shown in FIGS. 3 and 4. The catch 5 sits due to the spring force acting on it with its free end in the slot opening 10 of the housing 1. The position of the catch 5 according to FIGS. 3 and 4 means that the door is unlocked, but the catch 5 is locked. An actuation of the handle body 3 is thus only possible when the catch 5 has been moved out of the slot opening 10 with the aid of the key 23.

Die beiden Endstellungen des Verschlusses werden dadurch definiert, daß der Mitnehmer 2 eine radiale Bohrung 29 mit einer darin einendig mittels Splint abgestützten Schraubenfeder 30 aufweist, die anderendig eine Rastkugel 31 belastet, welche in um 90 Winkelgrade zueinander versetzte Rastausnehmungen 32 am Gehäusemantel einzurasten vermag. Zudem sorgt der Anschlag 11, der am Gehäuse 1 angeformt ist, für eine Schwenkwegbegrenzung.The two end positions of the closure are defined by the fact that the driver 2 has a radial bore 29 with a helical spring 30 supported therein at one end by means of a cotter pin, which at the other end loads a locking ball 31, which is able to engage in locking recesses 32 on the housing shell offset by 90 degrees from one another. In addition, the stop 11, which is integrally formed on the housing 1, limits the swivel path.

An der Befestigungsplatte 6 sitzt ein Endschalter 33 mit Tastfühler 34, der über einen am Mitnehmer 2 angeordneten Steuernocken 35 betätigbar ist.On the mounting plate 6 there is a limit switch 33 with a touch sensor 34 which can be actuated via a control cam 35 arranged on the driver 2.

  1. Closure means for the exterior swinging doors of buses, characterized in that said closure means can be arranged on the door in the inside of the bus and is essentially composed of a cylindrical housing (1) with a fastening plate (6) fitted thereon at one end, of a driver (2) which is mounted in a rotationally movable manner on the housing (1) and is intended for locking rods (14) which, by means of their free ends, can be pushed into, and drawn out of, mutually opposite latching receiving means of the door frame, of a handle element (3) which is connected in a rotationally fixed manner to the driver (2), of a cylinder lock (4) which passes through the handle element (3) and is received in a rotationally fixed manner in a bore of the driver (2), and of a catch (5) which can be actuated, counter to the force of spring means, via a key (23) of the cylinder lock (4), the catch (5) always being located, when the locking rods (14) are in the unlocked position, in a latching position which blocks rotation of the handle element (3), with the result that locking of the door can be carried out only by means of the key (23), but unlocking of the door can be carried out without the key (23).
  2. Closure means for exterior swinging doors according to Claim 1, characterized in that the catch (5) is arranged displaceably in an opening (27) crossing through the driver (2) and is seated, by means of its free end remote from the spring means, in a radial slot opening (10) of the housing (1) when the locking rods (14) are located in their unlocked position, drawn out of the latching receiving means of the door frame.
  3. Closure means for exterior swinging doors according to Claim 1 or 2, characterized in that, for actuation of the catch, an eccentric pin (22) is arranged, such that it projects in the axial direction, on the cylinder lock (4), said pin engaging into an entraining opening (25) of the catch (5).
  4. Closure means for exterior swinging doors according to at least one of Claims 1 to 3, characterized in that the driver (2) is formed with an annular gap (15) which receives the free end region of the housing (1) over an axial length region.
  5. Closure means for exterior swinging doors according to at least one of Claims 1 to 4, characterized in that the driver (2) exhibits a radial bore (29) with a helical spring (30) which is supported therein by one end and, at the other end, loads a latching ball (31) which can latch into latching recesses (32) offset by 90 degrees with respect to one another on the outside of the housing.
  6. Closure means for exterior swinging doors according to at least one of Claims 1 to 5, characterized in that the cylinder lock (4) is fastened on the driver (2) by a screw (21) which passes through a radial bore of the driver shank.
  7. Closure means for exterior swinging doors according to at least one of Claims 1 to 6, characterized in that seated on the fastening plate (6) is a limit switch (33) with sensor (34), which can be actuated via a control cam (35) arranged on the driver (2).
  8. Closure means for exterior swinging doors according to at least one of Claims 1 to 7, characterized in that the catch (5) is designed in the form of a rectangular plate with rounded longitudinal ends and exhibits lateral recesses (26) for receiving helical compression springs (24).
