Definitions

  • the invention relates to a lock for a door, a window or the like.
  • the pinion mounted in a lock case or the like being designed as a radially slotted ring is, which is penetrated by a lock cylinder, the eccentrically mounted to the pinion engages in the slot of the pinion and is drive-connected to the latter.
  • a lock of this type is already known.
  • the locking cylinder can be either a commercially available profile cylinder or a conventional round cylinder. In the latter, the cylindrical part with a circular cross section is larger than in the normal profile cylinder.
  • both are equipped with a flat housing part which is rounded at its free end and has a recess at its inner end for rotating the locking bar.
  • the flat housing part is provided with a thread through which a fastening screw, which is only accessible when the door is open, is screwed through.
  • the lock bit is located on a drive ring which can be rotated in a known manner by means of a key belonging to the lock.
  • the centers of the slotted pinion and the drive ring are offset from one another in the longitudinal direction of the flat housing part, which is why the slide type is mounted eccentrically to the pinion, that is to say the trajectory of the locking bit does not run concentrically with the geometric pinion axis.
  • the lock housing has an opening on its base and cover, through which the lock cylinder can be inserted.
  • This breakthrough is like a keyhole. Its exact shape depends on the locking cylinder to be used.
  • the shooting cylinder is displaced in the radial direction of the pinion or in the longitudinal direction of its flat housing part until the threaded bore of the flat lock cylinder housing part is aligned with the axis of the fastening screw. When the latter is fully screwed in, the lock cylinder has assumed its final, secure position in the lock.
  • round cylinders are also used, as mentioned, but there are differences in the position of the axis of the drive ring, which is arranged eccentrically to the housing part which is circular in cross section. In connection with this there are also radial differences in length of the mustaches. The longer lock bit naturally has a larger flight circle diameter than the shorter one.
  • the outer contour of these different round cylinders is, however, the same in the customary embodiments, so that the same shape can be used with regard to the lock openings for the round cylinders.
  • the slotted pinion is penetrated in the axial direction by the locking cylinder. For this reason, it can only be stored on its outer circumference. This storage is easy with conventional profile cylinders (Hahn cylinders). However, it can be difficult in the case of round cylinders with a long lock bit because the outer diameter of the pinion and the flight circle of the lock bit intersect. On the other hand, however, efforts are being made to design such locks universally so that all customary round and profile cylinders can be used. This is also the object of the present invention.
  • the lock is designed according to the preamble of claim 1 in accordance with the characterizing part of this claim.
  • the guide edge of the pinion which engages in the circular-shaped groove between the guide wall and the guide bar, ensures secure pinion guidance during rotation and the crescent-shaped shape of the guide bar enables the unhindered, despite the eccentric arrangement of the cam lock flight circle with respect to the geometric pinion rotation axis or the guide wall, even with a comparatively long cam lock Rotation.
  • the outer dimensions of the various round cylinder housings are the same, and there are no differences with regard to the radial spacing of the thread for the fastening screw from the geometric axis of the round lock cylinder housing part, only the flight circles of the mustaches are different in size and there are different eccentricities of the centers of rotation , the inner contour or the radius of the inner wall of the crescent-shaped guide rail depends on the flight circle of the longest locking bar of the usual round cylinders. This means that there is automatically enough space available for shorter mustaches and for beards of normal commercially available profile cylinders.
  • the crescent-shaped guide bar advantageously extends over an angle of approximately 180 °, which ensures good guiding of the pinion and there is sufficient movement space for the lock bit for all conventional locking cylinders and types of installation. If possible, the angle should not be less than about 150 ° and its maximum value for today's locks and lock cylinders is around 190 ° .
  • a further development of the invention provides that the guide bar and the guide wall are attached, in particular molded, to a guide body connected to the lock case.
  • the separately manufactured guide body provides a particularly universal lock, because the guide body can possibly be replaced by another lock part which serves the same purpose, but permits a further variation of the lock cylinder.
  • the guide body is preferably made of die-cast material, in particular of die-cast zinc, which ensures high accuracy and thus ultimately leads to the smoothness and robustness of this lock. The same applies to the manufacture of the pinion.
  • a lock case 3 On the bottom 1 and on the cover 2 of a lock case 3 there are each an essentially keyhole-like push-through opening 4 or 5 for a lock cylinder 6.
  • This has a flat housing part 7 and a housing part 8 with a circular cross section.
  • a drive ring 9 is rotatably mounted eccentrically , from which a locking bit 10 protrudes radially.
  • the flat housing part 7 has an opening 11, which allows the passage of this housing part through the lock bit.
  • a threaded bore 12 for screwing in a fastening screw 13 the head of which is accessible only when the door is open or the window equipped with this lock is open.
  • the flat housing part 7 passes through the radial slot 14 of a slotted ring-shaped pinion 15. Its inner diameter 16 is dimensioned such that the lock cylinder with the largest round housing part 8 can also be inserted.
  • the locking cylinder is, however, after being pushed through the pinion 15 in the radial direction, with its flat housing part 7 first in the direction of the arrow 17, that is normally moved downwards until its threaded bore 12 is aligned with the axis of the fastening screw 13, so that the latter can be screwed in .
  • the round housing part 8 according to FIG. 1 then engages behind the pinion at its lower area, which is assigned to the screw 13.
  • the geometric axis of the pinion 15 is designated 18.
  • the geometric axis 20 of the drive ring 9 with the locking bit 10 is offset downward on the vertical axis of symmetry 19.
  • lock cylinders in particular other round cylinders, can also be used in the lock.
  • Another such round cylinder has, for example, a drive ring with a shorter cam 21, the geometric axis of which is designated 22.
  • the eccentricity here is somewhat less than that of the embodiment with the lock bit 10.
  • a correspondingly shorter opening 23 can be present.
  • the external dimensions of these two locking cylinders are the same, as is the distance between the threaded bores 12 from the upper end of this locking cylinder in FIG. 1.
  • the locking cylinder passes through the ring-shaped pinion in the axial direction, it can only be supported on its outer circumference.
  • the storage must be designed so that all commercially available round cylinders, but also the normal profile cylinders with a round housing part that is much smaller in diameter, can be used in this lock and that there is sufficient space for the rotary movement of the locking bar.
  • the decisive factor is the flight circle of the locking bar compared to the pinion, which is arranged eccentrically at least in the case of the round cylinders.
  • the pinion size in such locks is not freely selectable, at least as far as the outer diameter is concerned, because the available space is limited.
  • the pinion driven by the key and thus the lock bit works in a known manner with a gear 24 of the lock, which has a fixed translation and thus also has a very specific space requirement.
  • gears are known, which is why they are not described in detail.
  • the last pinion of this gear acts on a rack which is coupled to a drive rod 25 which, in a manner not shown, carries a locking pin or the like which interacts with a striking plate on the fixed frame.
  • a lock bolt 26 can be moved back and forth in the sense of the double arrow 27 via this gear and known intermediate links, i.e. be locked in and out.
  • the Sch mayge housing therefore has an arcuate guide wall 28 in its area above the axis 18 and the pinion 15 is equipped with a concentric, axially projecting annular guide edge 29. In the exemplary embodiment, this arises from the fact that the pinion on its left-hand end face in FIG. 2 is equipped with a concentric, circumferential annular groove 30.
  • Their cross section can be semicircular or in a comparable manner.
  • the guide edge 29 is gripped behind by a crescent-shaped guide bar 31, specifically according to FIG. 1, only in the upper area, i.e. opposite the flat housing part 7 of the lock cylinder 6 or in FIG. 1 above the pinion center 18.
  • the crescent-shaped guide bar is limited by two circular cylindrical surfaces.
  • the outer one is concentric to the geometric axis 18 of the pinion 15 or to the guide edge 29, while the inner one is located concentrically to the trajectory of the locking bar 10 or 21, which projects the most in the radial direction.
  • Fig. 1 also shows a spring-loaded transport lock 32, which engages in the toothing of the pinion 15 and ensures its position during transport and before the insertion of a locking cylinder.
  • This transport lock is released via the pointed free end of the fastening screw 13. When the screw is unscrewed, it is reactivated so that after the locking cylinder has been removed, an inadvertent rotation of the pinion 15 is avoided and the new locking cylinder can be used without any problems.
  • a guide body 33 which preferably consists of die-cast zinc and is held or attached to the floor 1 in a suitable manner.
