Definitions

  • the invention relates to a lock, in particular for swing doors of buses.
  • Outer swing doors of buses or the like. can usually be opened and closed from the driver's seat, generally using compressed air.
  • doors can also be opened by means of manually operated door emergency opening levers which are arranged in buses above the doors and are connected to the opening mechanism thereof in order to unlock the door.
  • the invention has for its object to provide a closure for such swinging doors of buses, which should make it possible to secure the doors during longer downtimes of the buses, so that they do not close, even in the event of a possible failure of the compressed air system open, but at the same time ensure that the outside swing doors locked from the outside can be opened from the inside at any time, for example to give an accidentally locked passenger the opportunity to leave a bus despite the doors being closed.
  • the closure should be a compact design, good looks and are easy to manufacture, assemble and operate.
  • the object of the present invention to achieve the above object is a closure, in particular for swinging doors of buses, consisting of a housing to be fastened to a door, which has an outer and an inner handle body and an engaging driver for unlocking or locking the pulling rods effecting the door are mounted in a rotatable arrangement, the outer handle body being in engagement with the driver in the sense of a locking and unlocking movement and the inner handle body in engagement with the driver only in the sense of an unlocking movement, and wherein the outer handle body is equipped with a cylinder lock to ensure the rotational mobility to block it.
  • the new closure consists of a housing 1, an outer handle body 2 with cylinder lock 3, an inner handle body 4 and a driver 5 for tie rods 6.
  • the housing 1 has an approximately square outline contour with a circumferential flange 8, which is supported on the door 7, a housing recess 9, a bush-shaped bearing receptacle 11 with a base 12 which adjoins the bottom 10 of the housing recess 9, a central bore 13 in the base 12 and an eccentrically arranged pin 14 projecting above the base 12.
  • a semicircular slot opening 18 is formed in the bottom 12 of the housing recess 9.
  • the bearing receptacle 11 of the housing 1 is provided with a radially aligned slot opening 19 which passes through the bearing receptacle 11 and is located in the vicinity of the base 12.
  • the outer handle body 2 has a two-winged handle knob 21, which finds a substantially recessed receptacle in the housing recess 9.
  • On the back of the handle knob 21 there is an integrally formed with the outer handle body 2 receiving housing 22 which receives the cylinder lock 3, which or the like in the receiving housing 22 by a spring pin 23. is set.
  • the receiving housing 22 is cylindrical, has a perforated base 24 and an adjoining central pin 25 for a fastening element 26.
  • the receptacle housing 22 is rotatably mounted in the bearing receptacle 11 of the housing 1 and passes through the bore 13 in the bottom 12 of the bearing receptacle 11 with the pin 25.
  • the receptacle housing 22 also has a slot opening 27 which is aligned with the slot opening 19 of the bearing receptacle 11 when the handle knob 21 is in a central position, as shown for example in FIG. 1. If the slot openings 27 and 19 are aligned with one another, a locking bolt 29 can be moved into the slot openings 19, 27 by means of a key 28 to be inserted into the cylinder lock 3, so that the outer handle body 2 is secured against rotation on the housing 1.
  • the work of the cylinder lock 3 is designed so that the key 28 can only be inserted into the cylinder lock and can be removed again when the handle knob is in its central position according to FIG. 1.
  • the outside handle body 2 also has an eccentrically arranged driver pin 3o on its rear side, which extends parallel to the receiving housing 22.
  • the driver pin 3o first penetrates the semicircular Slot opening 18 in the housing 1 with the result that the outer handle body 2 can only be rotated over a pivoting range of approximately 180 degrees.
  • a restoring spring 31 which overlaps the bearing receptacle 11 and which is supported with one leg end on a housing projection (not shown) and with the other leg end on the driver pin 3o ensures that the handle knob 21 is always held in its central position according to FIG. 1 or after actuation is returned to this position.
  • the driver 5 has a hollow cylinder 32 encompassing the bearing receptacle 11 of the housing 1, a link groove 33 extending over an angular range of approximately 90 degrees and a two-armed flange 34 formed on the outside of the hollow cylinder, on the arm ends of which there are hanging eyes 35 or the like. for the tie rods 6.
  • a material attachment 36 which is formed in one piece with the driver 5 and which is provided with a bore 37 which is oriented perpendicularly to the axis of the hollow cylinder 32 and also penetrates the hollow cylinder 32.
  • the bore 37 receives a ball 38 that can be rolled off on the outer casing of the bearing receptacle 11 of the housing 1 and a compression spring 39 that loads it and is supported by a spring pin 40.
  • the ball 38 engages in one of the two latching recesses 20 of the bearing receptacle 11, around the driver 5 either in its locking position, which is shown in FIG. 4 with solid lines, or in its unlocking position, which is shown in FIG. 4 with dash-dotted lines is to keep solvable.
  • the driver pin 3o engages a slotted groove end in order to move the driver 5 into the locking or unlocking position (see FIG. 4).
  • the outer handle body 2 pivots back into its central position according to FIG. 1, supported by the return spring 31, the driver pin 3o freely passing through the link groove 33, in order then to contact the other link groove end.
  • the tie rods 6 must run over dead center when moving from the locking position into the unlocking position because they are each connected to the flange 34 of the driver 5 outside the horizontal 41.
  • the tie rods 6 can thus be used in the event of an attempted break-in, e.g. when placing a tool in the door seal area, do not unlock.
  • the inner handle body 4 has a two-part construction and consists of an adapter 42 and a grip wheel 43 connected to it.
  • the adapter 42 is designed like a socket and has a bottom 44 which is surmounted by a cylindrical extension 45.
  • a central bore 46 and an arcuate recess 47 are formed in the bottom 44 of the adapter 42.
  • the adapter 42 is attached to the bearing receptacle 11 of the housing 1, the bottoms 12 and 44 coming to lie against one another, the pin 25 passing through the bore 46, the pin 14 passing through the recess 47 and the extension 45 passing through the hollow cylinder 32 of the driver 5 in some areas spreads.
  • the adapter 42 is fixed to the housing 1 by means of the fastening element 26, which can be, for example, a screw that taps its thread, a washer and a toothed disk that prevents the screw from loosening.
  • the arcuate recess 47 with the pin 14 engaging therein allows only a rotational movement of the inner handle body 4 in the sense of an unlocking movement. An extension of the recess could of course also result in a closing movement of the inner handle body and thus a locking of the vehicle door from the inside, but this is not desirable for various reasons.
  • the extension 45 of the adapter 42 has an interruption 48, in which the material approach 36 of the driver 5 engages. If the material approach 36 abuts the end 49 of the interruption 48 (in this case, the tie rods 6 are in the locking position), the driver 5 can be transferred into its unlocked position (shown in dash-dot lines in FIG. 4) by turning the inner handle body 4. After the unlocking movement, the inner handle body 4 automatically rotates back into its starting position, for which purpose a return spring 5o is provided, which is supported with one leg end on the pin 14 and with the other leg end in a slot opening 51 of the adapter 42. The restoring movement is stopped by the other end 52 of the interruption 48, which comes into contact with the material attachment 36.
  • the adapter 42 has clip lugs 53 at its free end, which are engaged by spring arms 55 of the grip wheel 43 provided with locking lugs 54. Mounting openings 56 allow disassembly if necessary.
  • the closure according to the invention which can be assembled quickly and easily with the interposition of sealing elements 57, 58, which are intended to prevent the ingress of moisture or moisture into the interior of the door, is distinguished in various respects. Since the outer handle body 2 can only be turned when the key 28 is inserted, actuation of the same by unauthorized persons is ruled out. On the other hand, the lock can be easily operated using a key. Of particular advantage is the possibility given by the invention of being able to unlock and open a locked door easily from the inside. It is also advantageous that there is only one unlocking possibility for the inner handle body, because this can rule out that an unwanted locking is brought about by manipulations on the inner handle body. A locking mechanism not noticed by the driver could cause considerable damage when the door is opened using the automatic compressed air system.
  • the invention also provides, as a precaution, a safety device which, for example, consists of a warning lamp installed on the dashboard and indicates to the driver whether the lock is open or closed.
  • the warning lamp can be controlled, for example, via the vehicle electrical system and cooperate with a microswitch 59, which sits on a housing attachment 6o and is closed when the tie rods 6 are in the locking position.
