Definitions

  • the invention relates to an external swing door lock for buses.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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).
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the driver 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.
  • 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.
  • the new outer swing door lock has a cylindrical housing 1, a driver 2, a handle body 3, a cylinder lock 4 and a catch 5 as main components.
  • the cylindrical housing is formed at one end with a fastening plate 6, which is provided with perforations 7 for the passage of fastening screws.
  • the pot-shaped housing 1 is close to the mounting plate 6 through a base plate 8 which has a central bore 9 has closed.
  • the shaft of the housing 1 has a slot opening 10 into which the catch 5 can snap into place.
  • 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.
  • 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.
  • 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.
  • 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.
  • the driver 2 carries the handle body 3 in a non-rotatable arrangement via clip-like fastening elements 19.
  • 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.
  • 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.
  • the catch 5 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.
  • 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.
  • the driver 2 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.
  • 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.
  • a limit switch 33 with a touch sensor 34 which can be actuated via a control cam 35 arranged on the driver 2.
