Definitions

  • the invention relates to a rotary latch for doors or windows, with a bolt rotatable about an axis running at right angles to the door or window plane, which by means of a drive rod and a link connecting the drive rod with a rear part of the bolt from an open position to a closed position and is rotatable back, in the open position the bolt is essentially inside the door or window sash and in the closed position a hook-like and provided with a wedge-shaped front latch part engages through a recess arranged in a faceplate into a fastening part fastened to the frame and thereby engages behind a wall of the locking part.
  • a twist lock closure of this type is known from DE-PS 24 32 777.
  • the rotary bolt is mounted on a bracket attached to the faceplate and is only guided in the recess of the faceplate.
  • This design of a rotary bolt lock does not prevent with sufficient certainty that a closed door or window can be broken open by means of a crowbar.
  • the mounting of the rotating bolt and the guidance of the rear part of the bolt are inadequate and are not able to absorb larger forces acting transversely to the door or window level.
  • the well-known rotary bolt lock requires very specially designed face plates and drive rods and a very deep fitting groove in the casement.
  • the invention has for its object to provide a twist lock that offers maximum security against tampering with the smallest installation depth and easy assembly.
  • This rotary latch which can be pivoted by exactly 90 °, has the advantage that, in the closed position, the part guided in the housing is larger than the part swung out through the recess in the faceplate and engaging in the closing part. Since the rear part of the bolt is guided in the housing with only a small amount of play even in the closed position, very large forces acting transversely to the sash plane can be absorbed by the bolt without the bearing of the bolt being damaged.
  • the slide parallel to the drive rod in the housing is connected in a simple manner to the drive rod in that when the housing is screwed on, a lug of the slide engages in a recess in the drive rod. Only recesses and screw holes are to be provided in the drive rod and in the faceplate in order to be able to mount the rotary bolt lock.
  • the rotary bolt lock has a bolt 5 which can be rotated about the axis 6 and which by means of a drive rod 12 and one of the drive rod 12 with a rear part 15 of the bolt 5 connecting slider 8 is rotatable from an open position to the closed position shown and back. In the open position, the bolt is located essentially within the door leaf or the window leaf. In the closed position shown in FIGS. 1 and 2, a hook-like locking part provided with a wedge surface 20 engages in a locking part 16 fastened to the frame 1 and engages behind a wall of the locking part 16 or one Additional locking plate 17. In the drive rod 12 and in the faceplate 3, recesses 4 are incorporated, through which the bolt 5 extends.
  • the latch 5 has essentially the shape of a semicircle and is mounted within a housing 7 made of cast metal with a housing cover 7 '.
  • the housing 7, 7 ' encloses the bolt 5 on its circumference and on its sides with little play.
  • the housing 7 with the housing cover 7 ' also has a guide for a slide 8, 8', which can be inserted into a recess 22 of the drive rod 12 with a lug 11.
  • the slide or the two slide parts 8 and 8 'each have an elongated hole 9 into which a bolt 10 fastened to the bolt 5 engages.
  • the housing 7 or the housing cover 7 ' has screw-on flanges 23 and 24 with which the housing 7, 7' can be screwed onto the faceplate 3.
  • the bolt 10 can be formed by stub axles 10 and 10 'which are cast onto the bolt 5.
  • the axis 6 and the bolt 10 can also be steel bolts which are inserted into the bolt 5.
  • the latch 5 is guided over its entire depth within the housing. For this reason, it can also absorb extremely high forces acting transversely to the door or window level.
  • the groove for receiving the faceplate 3 and the drive rod 12 can be very flat, and the assembly of this twist lock is very simple because the slide parts 8 and 8 'and the latch 5 can be easily inserted into the housing 7,7' before the Housing cover 7 'is screwed on. Furthermore, it can closed housing can be screwed onto the faceplate 3.
  • the channel 13 engages around the drive rod 12 with play on the front of the housing.
  • a pocket can be formed in the bolt 5 for receiving a flat steel reinforcement which is inserted into this pocket.
  • This steel reinforcement 33 ensures that the bolt 5 cannot break even when the greatest forces are applied.
  • the hook-like nose entering the locking part 16 is provided on both sides with a wedge surface 20, so that when the rotary bolt lock is closed, the door or window sash is always tightened and the rotary bolt lock can be used in different arrangements.
  • guide webs 25 and 26 are integrally formed on the inner wall of the housing 7 and the screw-on cover 7 'in the region of the rear part 15 of a bolt 5 in the open position and in the region of the axis of rotation 6.
  • These guide webs 25 and 26 form pockets for receiving the locking parts 8 and 8 'shown in FIGS. 8 to 11 and 12 to 14.
  • Each locking part 8, 8 ' has a guide groove 18 which is guided on a guide rib 19 and 19' which is formed on the inner walls of the housing 7 and the housing cover 7 '.
  • the rotary bolt engages with its front hook-like part 14 from above or, depending on the arrangement, also from below behind the locking plate 17.
  • the bolt 5 has been rotated by 90 ° from its open to its closed position, then a reliable locking is achieved.
  • the bolt 5 ' has a lateral projection 34 which engages behind a wall 36 of a closing part 16'.
  • the rotary bolt lock can be used for different applications and the arrangement of several rotary bolt locks on a door leaf or a window leaf the locks can be arranged both closing in the same direction and closing in opposite directions, the bolt 5 'is equipped with a V-shaped tiltable catch 37, the greatest width is wider than the clear width of the closing part 16 '.
  • this tilting catch 37 can tilt to the right or left when entering the enlarged inlet opening 34, so that the tilting catch 37 engages behind a left or a right wall of the closing part 16 'in any case.
  • the tilting latch 37 is accommodated in a recess 38 of the bolt 5 'and is held by a web 39.
  • the tilting latch 37 expediently consists of sheet steel.
  • the bolt 5 'with the catch 34 engaging on the side has the advantage that the locking part 16' does not have to be aligned so precisely with respect to the bolt 5 'and that a reliable engagement is achieved despite a height offset.
