Definitions

  • the invention relates to a lock, in particular espagnolette lock, according to the preamble of claim 1.
  • locks in particular espagnolette locks, it is known to bend tabs cut free from the edge of the lock base facing the cuff and to connect these to the cuff either by spot welding or by riveting.
  • the lock base and cuff thus form a firmly connected unit, which will be assigned to the lock set-up during subsequent assembly.
  • Different types of locks require correspondingly designed units consisting of a cuff, lock base and lock fittings.
  • Different types of locks can e.g. be formed by the fact that there are different sizes of distance between the handle mandrel and the axis of rotation of the key. Furthermore, they can have different backset dimensions.
  • the object of the invention is based on the task of simplifying the manufacture of corresponding locks while increasing the possibility of variation. This object is achieved by the solution specified in claim 1.

  • the cuff and lock housing are connected via the fastening projections provided on the rear surface of the cuff and projecting over the narrow side walls of the lock housing. Therefore, there is good accessibility, which allows the cuff to be connected to the lock housing in the short term.
  • Bolts which are oriented parallel to the cuff are particularly suitable as a compound. If these are designed as screws, only the corresponding screws need to be brought into joint engagement to fix the cuff to the lock housing.
  • the fastening projections By inserting pockets on the narrow side walls for the fastening projections, it is possible to mount the cuff with the fastening projections on it by means of plug-in assembly. Then the bolts are then screwed into the threaded hole of the fastening projections while pushing through the pockets.
  • the insertion pockets are formed by bends from the lock base and lock cover. The end sections of the bends of the insertion pocket provided in a narrow side overlap.
  • the corresponding overlap area is penetrated by the bolt, which is screwed into the threaded bore of the fastening projection.
  • a multiple function is achieved by the fact that the fastening projections on the bearing blocks are provided for the drive rods penetrating them. Separate slot guides in the area of the lock housing can then be omitted for the drive rods.
  • the cuff with the drive rods form a firmly connected structural unit before assembly, which makes it easier to attach them to the lock housing.
  • the outer surface of the fastening projections, pockets, bearing blocks are designed to be convexly curved or have a corresponding course. The pocket to be incorporated into the door is therefore completely filled by the lock housing with bearing blocks and fastening projections as well as insertion pockets.
  • a bolt penetrating the lock base is used, which engages in a further projection protruding on the rear of the cuff.
  • This bolt can also be designed as a bolt. However, its alignment is transverse to the other two bolts, so that this course of the three bolts results in a particularly high fastening stability of the cuff on the lock housing.
  • the espagnolette lock has a lock housing 2 connected to a cuff 1.
  • the cuff 1 fastened to one narrow side of the lock housing 2 has a greater length than the lock housing 2 and extends over an upper and a lower drive rod 3 or, respectively, emerging from the lock housing 2. 4.

  • the fastening projections 9 projecting over the narrow side walls 6, 7 have a trapezoidal shape such that the base of the trapezium faces the interior of the lock housing.
  • both the lock base 10 and the lock cover 11 running parallel thereto form insertion pockets 12 and 13 on the narrow side walls.
  • the pocket 12 formed by the lock base 10 is obtuse-angled.
  • the angle section 12 ′′ is equipped with a passage opening 14 which is aligned with a threaded bore 15 of the fastening projection 9. Otherwise, this threaded hole runs parallel to the cuff 1.
  • the other insertion pocket 13 in turn also has an angular shape.
  • the angle leg 13 'starting directly from the castle ceiling 11 is supported on the facing oblique flank of the trapezoidal fastening projection 9.

  • the outer surface 18 of the bearing blocks 8 is convexly curved. Within this convex curvature also extend the outer surface of the fastening projections 9 and the insertion pockets 12, 13 formed by bends, cf. 5 and 6. This makes it possible to produce pockets on the doors which are adapted to the outline of the lock housing at the height of the bearing blocks 8.
  • Each bearing block 8 has a projection 19 with an oval cross section for fixing it on the cuff 1, which is inserted into a shape-adapted recess 20 of the cuff and riveted there, cf. 5 and 14 in particular.
  • the bearing blocks 8 form centering brackets 22 which are immersed in shape-matched edge recesses in the lock base 10 and lock cover 11.
  • the aforementioned centering tabs 22 are flush with the outer surfaces of the lock base 10 and lock cover 11.
  • the lower drive rod 4 is forked in the region of the section crossing the bearing block 8.

  • the drive rod connecting slide 53 controls the bolt closure with the interposition of a pivot lever 56 in such a way that first the drive rod connecting slide 53 leads the bolt exclusion and then the bolt 35 is taken along. As a result, only the locking members 5 can engage and bring about a tightening of the door, so that the locking bar 35 can then move freely into the striking plate recess facing it.
  • the bolt 35 has on its bolt tail 35 'an inclined to the direction of movement of the bolt 35 Run-up slope 57. This is formed by a lateral elevation 35 '''of the bolt tail 35'', which elevation 35''' leads on the lock base 10.

If drive rod locks with different backset dimensions are to be created, these structural units need not be modified. Rather, it is sufficient to lengthen or shorten the castle floor and castle ceiling, while the rear area remains unchanged including the bulges. Corresponding reductions and extensions are then to be made for the bolt and the latch and the connecting rod connecting slide 28. Due to this slight change, however, a large range of differently designed locks can be manufactured combined with reduced production costs and reduced storage.
