  • Figure 2 illustrates a first operative configuration wherein the lock assembly 100 is in unlocked state.
  • the pivoting hooks 50A, 50B are initially in a withdrawn position.
  • the stub 36 of slider 30 is in an unlocking slot 92B of locking bracket 90.
  • the drive lug 42 lifts the locking bracket 90 and pushes the side of driving slot 34 of the slider 30 which causes the slider 30 to be slideably displaced towards the striker 80.
  • pivoting hooks 50A, 50B are engaged with the slider with the help of the first protrusion 52, the pivoting hooks 50A, 50B are rotated in the direction of displacement of the slider 30 to facilitate pivoting of the pivoting hooks 50A, 50B.
  • the locking limb 56 is ejected out of the lock housing 10 to enter the striker slot 82 and brace against the striker to facilitate locking of the sliding door with the jamb.
  • the pivoting hooks 50A, 50B remain in locked state until the key is inserted again and turned in a reverse direction to do unlocking.
  • Figure 3 illustrates a second operative configuration wherein the lock assembly 100 is in a first intermediate state.
  • the locking means 12 receives the key which is angularly displaced in a first direction.
  • the drive lug 42 of the crank 40 is pushed against the locking bracket and lifting it in upward direction against the force of tension spring 70 and frees stub 36 of the slider 30.

  • the stub 36 of the slider 30 is free to move in slots 92A of the profile 92 of locking bracket 90 when the slider 30 linearly displaced forwardly.
  • Figure 4 illustrates a second operative configuration wherein the lock assembly 100 is in a second intermediate state.
  • the stub 36 of the slider 30 is free to move forward without hindrance towards the locking slot 92A.
  • the angular displacement of the crank 40 due to turning of the key causes further forward linear displacement of the slider 30.
  • the pivoting hooks 50A, 50B are provided angular displacement due to sliding of the slider 30, thereby causing an intermediate outward displacement of their locking limbs 56 in a partially locked state.
  • Figure 5 illustrates a fully locked state of the locking mechanism of the lock assembly 100.
  • the forward displacement of the slider 30, further from the position shown in Figure 4, brings the stub 36 in alignment with the locking slot 92A of the locking bracket 90.
  • the tension spring 70 immediately pulls the locking bracket 90 downwards to lock the locking slot 92A against the stub 36 of the slider 30.
  • no angular moment would be exerted on the locking bracket 90 due to a horizontal force on the slider 30 through pivoting hooks 50A, 50B in the operative reverse/inverse direction so stopping the angular play in pivoting hooks 50A, 50B.
  • the pivoting hooks 50A, 50B would remain outside of the lock housing 10 in the locked state, as shown in Figure 5.
  • Overall, a very secure state of locking is guaranteed by the locking mechanism realized by the locking profile 92 of the locking bracket 90 combined with the stub 36 of the slider 30.
  • the dimensions and the weight of the various links in the mechanism are optimized due to the configuration described above.
  • a driving recess 32 having an oblong shape is configured on the slider 30 to facilitate travel of the first protrusion 52 of the pivoting hooks 50A, 50B when the slider 30 is slideably moved.
  • the pivoting hooks 50A, 50B include a second protrusion 54 configured on the first surface 50’ of the body of the pivoting hooks 50A, 50B.
  • each of the pivoting hooks 50A, 50B has a stepped configuration, wherein the height of the first surface 50’ of the pivoting hooks 50A, 50B is lesser than the thickness of the body of the pivoting hooks 50A, 50B.
  • the stepped configuration of the pivoting hooks 50A, 50B allows the slider 30 to fit in and push the pivoting hooks 50A, 50B to the maximum extent. Further, the stepped configuration of the pivoting hooks 50A, 50B minimizes the overall thickness of the lock assembly 100.
  • the pivoting hooks 50A, 50B further includes a third protrusion 58 configured to extend from the second protrusion 54 to a second surface of the pivoting hooks 50A, 50B.

  • the overall configuration of the components of the lock assembly 100 allows the lock assembly 100 to maintain a thinner configuration as compared to the conventionally available locks for sliding doors. Further, the strength provided by the lock assembly 100 of the present disclosure is also greater than the conventionally available locks.
  • the lock assembly 100 of the present disclosure can be used in locking sliding doors of a wardrobe, cupboards and the like.

Abstract

La présente invention concerne et vise un ensemble de verrouillage pour une porte coulissante. L'ensemble comprend une structure de support (10, 20), au moins un crochet pivotant (50A, 50B) et un mécanisme d'actionnement. Le mécanisme d'actionnement comprend un coulisseau (30), une manivelle (40) et un support de verrouillage (90). La manivelle (40) peut être actionnée par les moyens de verrouillage (12). Le coulisseau (30), monté sur la structure de support (20), coulisse le long d'un plan parallèle au plan de la structure de support (20). Le coulisseau (30) est relié au crochet pivotant (50A, 50B) pour faciliter sa rotation vers un état verrouillé à partir d'un état déverrouillé et vice versa. Le support de verrouillage (90) est rotatif et présente un profil de verrouillage (92) qui permet le verrouillage du coulisseau (30) et par conséquent amène le crochet pivotant (50A, 50B) dans un état verrouillé ou dans un état déverrouillé.
