Definitions

  • the invention relates to a striking plate for door locks, in particular for hollow plastic profiles, with a latch recess intended for receiving a lock latch, and with a latch stop part delimiting the latch recess on one side, which is adjustable relative to the striking plate in the direction of movement of the latch, but one against unwanted adjustment has locking groove engagement transversely to the direction of adjustment, which is secured by fastening the stop part.
  • Strike plates for door locks are usually provided with a punched recess into which the latch falls when the door leaf is closed. Since the latch stop part is rigidly connected to the striking plate, there is no possibility of adjustment once the striking plate has struck the frame. As a result, it cannot be ruled out that the latch has play in the latch recess when the door is closed, so that the door rattles. But it can also be the case that the latch cannot intervene in the latch recess due to incorrect assembly of the striking plate. In the latter case, it is common to either bend or file the latch stop part. In both cases, however, irreparable damage occurs.
  • Both parts therefore have a grooved or toothed surface area which is secured by fastening the stop part.
  • a screw connection is used for fastening.
  • the fastening screws penetrate the striking plate and / or its stop part and the locking grooves located between the two and engage in the frame material.
  • this intervention is unreliable. It has been found, for example, that the striking plate and its latch stop part are not exactly in the engagement groove engagement during assembly, because a relative transverse position of the two parts was possible due to the tolerances of fastening holes and fastening screws. Other tolerances of the striking plate and the latch stop part can lead to a correct engagement of the groove not available. In addition, the attachment can come loose over time because the attachment parts such. B.
  • the invention has for its object to improve a striking plate of the type mentioned so that disengagement of the striking plate and latch stop part is not possible by loosening the attachment of the stop part.
  • the arrangement of the locking grooves perpendicular to the main plane of the striking plate is important because the locking grooves are not only arranged transversely to the adjustment direction, but also such that they extend over a larger height range in the direction of the attachment of the stop part.
  • loosening or loosening of this fastening does not lead to the locking grooves of the striking plate and the latch stop part coming out of engagement.
  • the locking grooves are provided on the narrow edges of the stop part on the one hand and on the narrow edges of the striking plate forming a stop part recess on the other hand.
  • the latter at least partially takes the place of the striking plate in the region of the stop part recess. This results in an essentially undisturbed outer circumference of the striking plate, if one disregards the comparatively minor impairments caused by adjusting the latch stop part.
  • An overlap of areas of the striking plate and areas of the latch stop part in the vertical is avoided, which in addition to the improved appearance also results in a reduction in material consumption.
  • the locking grooves are formed only on part of the length of the narrow edges on the trap inlet side. Such a reduced intervention is sufficient because the stressing forces occur there.
  • the narrow edge length of the latch stop part having the locking grooves is smaller than the narrow edge length of the striking plate having the locking grooves.
  • the shorter narrow edge length of the latch stop part is sufficient because the latter is adjusted relative to the striking plate for adjustment, so that the narrow edge length of the latter must take into account the adjustment range of the stop part and must be correspondingly longer.
  • the locking grooves each extend over the entire height of the narrow edges of the striking plate forming the stop part recess and the narrow edges of the stop part. This design ensures a high degree of connection security because the narrow edges would have to be disengaged over their entire height perpendicular to the main plane of the striking plate. Such loosening or loosening of the parts securing the fastening and thus the locking groove engagement is, however, not to be expected.
  • the striking plate has an externally projecting ledge on the latch inlet side and the latch stop part has an equally projecting ledge provided with a corresponding cross section and forming the latch recess.
  • their bar takes the place of a projection or a longitudinal bar of the hollow profile on which the striking plate is to be fastened.
  • the additional, projecting ledges serve to stabilize against torsion. This applies in particular to the striking plate.
  • the stop part there is also the fact that the bar forms the latch recess, namely insofar as it overlaps with the latch when the door is closed.
  • This bar of the stop part also forms a headstock for the trap that opens when the door closes.
  • the end faces of the strips of the stop part and the striking plate are also in locking engagement with one another.
  • the latching engagement is not only increased, but is also present at the point which is closest to the point of application of the force of the trap. This is particularly useful for locking engagement security.
  • the lengthening of the locking grooves also increases the security of engagement, because the bars, which are high compared to the sheet thickness of the striking plate, have to be completely pulled apart before the engagement is released.
  • the latch stop part has longitudinal fixing holes aligned in its direction of adjustment.
  • the striking plate 10 shown in FIG. 1 essentially consists of a plate 30 which determines the main plane 19 of the striking plate 10 shown in FIG. 6, which is the same as the plane of representation of FIG. 1. It has a recess 31 for the engagement of a bolt of a door lock and a recess 25 for receiving a stop part 16. While the recess 31 is closed, the recess 25 is open on one side of the plate 30, so that the striking plate 10 in the region of the recess 25 has only one web 32, see also FIG. 2.
  • the plate 30 is fastened to the fixed door frame with fastening screws which are inserted through holes 33 in the plate 30.
  • the plate 30 in the region of its edge 30 'frame side has a flat 34, the Installation serves. Opposed to this flattening 34 there can be cams 35 on the top of the plate 30, which serve to clamp the striking plate 10 to the profile 12 of the fixed frame.
  • the plate 30 In the area of its other edge 30 ⁇ , the plate 30 has a projecting strip 26, which forms the latch recess 15 by its projection.
  • the strip 26 is provided on the hollow profile side with a recess 36 which, according to FIG. 6, serves to support the strip 26 on a projection 37 of the hollow profile 12.
  • the narrow edges 23 of the striking plate 10 are provided with latching grooves 21 which extend over the length L, which is smaller than the total length of the narrow edge 23 or the depth of the recess located in the plane of the plate 30 25 is.
  • the locking grooves 21 can also be found in the region of the end face 28 of the strip 26.
  • a stop member 16 is inserted into the recess 25. Its profile is adapted to the profile of the striking plate 10. This is shown in Fig. 4. In this figure it is also shown that the narrow edge 24 of the stop member 16 is only provided over its length 1 with locking grooves 22, but which also extend over the entire height of the end face 28 'of a strip 27. By comparing the end faces 28, 28 'of the strips 26, 27 and the areas of the narrow edges 23, 24 provided with grooves 21, 22, it follows that the engagement groove engagement 17 is comparatively large.
  • FIG. 3 shows in view A of FIG. 1 chamfer 37 of the back of the bar 27 of the stop member 16.
  • the hollow profile 12 of the fixed door frame shown in FIG. 6 is adjacent to the hollow profile 13 of the door leaf, that has a rollover 13 '.
  • a door lock 11 is installed in the door leaf, the latch 14 of which projects and projects into the latch recess 15.
  • the latch recess 15 is formed by the bar 27 of the latch stop part 16, which overlaps with the latch 14 according to FIG. 6.
  • the latch 14 comes into the position shown when the door wing runs in the direction 18 into the door recess formed by a plurality of hollow profiles 12.
  • the striking plate 10 is installed in such a way that its flattened portion 34 is inserted under a projection 38 which also serves to accommodate a center seal. Then the strip 27 is placed on the projection 37 of the hollow profile 12 and the plate 30 can be fastened with fastening screws inserted through the holes 33. Then the stop part 16 is installed by bringing it vertically downward into the desired position in FIG. 6, the locking groove engagement 17 being produced. Fig. 6 shows the stop part 16 in its target position. If it turns out that the distance between the bar 27 of the stop part 16 and the latch 14 is too large, the stop part 16 is moved to the left in FIG. 6, so that the free recess 25 of the striking plate 10 is reduced. The resulting recess from the outer surface of the profile 12 is insignificant and is covered by the rollover 13 'when the door leaf is closed.
