Definitions

  • the invention relates to an espagnolette lock with a latch and a bolt which, like the locking elements, can be moved into the unlocking position by pushing up the respective handle and by pushing down the handle located on the inside of the door, with a key-operated locking cylinder.
  • the different locking elements such as locking pins and bolts
  • the locking elements are unlocked by pressing the lever handle down.
  • the latch is separated from the other functions with the Key operated via the locking cylinder. If the locking elements are not brought into the final position by pulling up the lever handle, only the lock latch is actuated by pressing the lever handle down.
  • a pushrod lock which can be actuated by means of a pusher and which can be closed by means of a key and a nut having an opening for a pusher arbor is known, which has at least one pushrod in via a positive engagement with a coupling element when rotating in the opposite direction to the latch actuation Pushes the closed position, and with a control segment displaceable by key actuation, which decouples the positive drive connection between the nut and the drive rod when the key is turned into the closed position when the drive rod is in the closed position.
  • there should be an engagement lock between the nut and the coupling element which after the key is turned in the unlocked position is only lifted in a certain relative position between the nut and the coupling element.
  • the engagement lock is formed by a nose support surface of the lock nut, which cooperates with a nose of the coupling element.
  • the coupling element is a rack pivotably mounted between its ends on a connecting rod connecting piece, which has one end of the nose, to which a counter toothing meshing with a toothed segment of the nut connects, and which otherwise interacts with the control segment via a pin / recess handle, the toothed rack passing through Displacement of the control segment up to the coupling or uncoupling of the tooth engagement can be pivoted through an angle.
  • the pin / recess handle is lifted in the open position of the drive rod, the pin moving into the recess open to the edge of the control segment when the drive rod is displaced in the closed position.
  • the toothed segment of the nut should have two toothed side edges, the nose contact surface cooperating with the control section adjoining one toothed side edge.
  • the gear is to be arranged non-rotatably on a rocker with its end forming the slot / pin engagement to the bolt and is guided in a longitudinally movable manner relative to the touring pusher, in that the stationary one Rack is opposite a rack of the touring pusher that meshes with the gear running parallel.
  • the rocker lies in a rear recess in the broad area of the bolt tail.
  • the touring pusher is fork-shaped and overlaps the broad sides of the bolt tail and is guided with a rib in the lock base and carries a tumbler plate that can be controlled with a rear-facing shoulder in front of and behind a housing pin.
  • the gearwheel axis and the rocker pin lie in the dead bolt position on a dead center line extending in the dead bolt direction.
  • the invention is based on the object of designing an espagnolette lock of the required type in such a way that it locks from the outside and inside of the door - that is, all bolts are extended - but only from the outside a key can be opened again, which also applies to the additional bolts.
  • espagnolette lock can be locked from the inside by pulling up the lever handle and can be unlocked again by pushing it down, as can be unlocked from the outside by pulling up the lever handle, but cannot be unlocked again by pressing the lever handle down. This is only possible by pressing the key.
  • a further return part is provided which surrounds the corresponding square and which, by means of spring pressure, erects the door handle again after it has been pressed down.
  • the invention also enables a simple, compact spatial shape.
  • One, continuously and larger in diameter The square of the handle arbor is located on the inside of the door, while the other, separate handle part is on the outside of the door.
  • the change-over slide interacts on the one hand with the key or a key bit that can be actuated by the key, and on the other hand acts on a slide to move it into a position in which the two lock nut parts are non-rotatably coupled to one another.
  • Claim 2 describes the special lock nut structure. Since the parts are inserted into each other, this nut builds very compact, so that the outer dimensions of the lock do not increase. Compared to conventional multi-point locks of this type, no change in dimensions can be seen from the outside.
  • Claim 4 describes the retrieval member, while Pa tent pipe 5 illustrates a latch.
  • Claim 7 describes a rod drive and Pa tent Claim 8 the locking drive.

This is due to the fact that the slider 76, which is moved downward, that is to say in the direction Y (FIG. 2), causes the sector-shaped recesses 85 and 86 of the slider 76 to coincide with the corresponding kidney-shaped recesses of the nut body 55 (FIG. 29).
