  • the present invention relates to a latch assembly according to the preamble of the claim 1.
  • the latch assemblies with handles are known in the art. Such latch assemblies are used in panels, industrial machines, or cabinet doors.
  • latch assemblies in the art are mostly available in the market as mechanical cabinet locks. When only the mechanical lock is used, it is not possible to get information on whether the door is open or closed. There is a need of a latch assembly in which electronic and mechanical opening options work together. Moreover, such latch assemblies are generally formed of a single locking component. Frequently a need exists for added locking features such as the use of a padlock or the like.
  • US2002112511 A prior art publication in the technical field of the invention may be referred to as US2002112511 (A1 ), which discloses a double lock T-handle having a tray which includes an inwardly dished handle receiving area, a second recessed handle receiving region, and a recessed padlock receiving depression.
  • the primary object of the invention is to provide a latch assembly that allows both mechanical and electronic locking operations with increased security.
  • Another object of the invention is to provide a latch assembly having an electronic unit that informs whether the door of the cabinet or the like is open or closed.
  • Another object of the present invention is to provide a system in which the handle can be easily blocked so that the latch assembly cannot be unlocked.
  • Another object of the present invention is to include a lock plug suitable to be used with a key that also allows mechanical use.
  • Another object of the invention is to provide a latch assembly in which if the door is not opened for a certain period of time when it is triggered to unlock, the lock can lock itself within a certain period of time.
  • Another object of the invention is to provide a latch assembly that allows the lock to be opened with a key from the front of the door and by pressing the back side of the door.
  • Another object of the invention is to provide a latch assembly that includes a remote control to enable remote locking.
  • the present invention relates to a latch assembly comprising a main body; a handle pivotable mounted on the main body for movement between a normally closed position and open position; a pivotably mounted locking hook in communication with a spring-biased triggering member for locking and unlocking the latch assembly; a locking lever having two spaced apart arms attached to opposite sides of the main body; an attachment pin guided in the main body and mechanically connected to the handle and at least one of the arms of the locking lever; an electronic circuit for triggering a motor unit wherein the motor unit is operatively connected to a locking tongue being movable between unlocked and locked positions.
  • the proposed locking tongue is arranged to operatively engage a locking slot formed on one of the arms of the locking lever when the locking tongue is brought to the locked position.
  • the present invention proposes a latch assembly (10) comprising a main body (20); a handle (30) pivotable mounted on the main body (20) for movement between a normally closed position and an open position; a pivotably mounted locking hook (22) in communication with a spring biased triggering member (24) for locking and unlocking the latch assembly (10); a locking lever (50) having two spaced apart arms (52a, 52b) attached to opposite sides of the main body (20); an attachment pin (28) guided in the main body (20) and mechanically connected to the handle (30) and at least one of the arms (52) of the locking lever (50); an electronic circuit (29) for triggering a motor unit (25) wherein the motor unit (25) is operatively connected to a locking tongue (40) being movable between unlocked and locked positions.
  • the locking tongue (40) is arranged to operatively engage a locking slot (51) formed on one of the arms (52a) of the locking lever (50) when the locking tongue (40) is brought to the locked position.
  • Both arms (52a, 52b) are in contact with the attachment pin (28) and one of the arms (52a) has an extended portion (53).
  • This extended portion (53) preferably extends parallel to the longitudinal axis of the latch assembly (10) and includes said locking slot (51) at its end.
  • the locking lever (50) which is normally connected with the attachment pin (28) and suitable for pivotal movement, does not pivot when the locking tongue (40) at least partly enters the locking slot (51).
  • This extended portion (53) is preferably provided only one of the arms (52a).
  • a substantially U-shaped locking lever (50) is mounted to the handle (30) with the cylindrically shaped attachment pin (28) which ensures main parts of the latch assembly (10) move together as a one-piece system.

  • the handle (30) has a holding portion (31) arranged to be held by the user and has two oppositely arranged guiding legs (32) extending from the holding portion (31). So, the handle (30) is arranged to pivotable release the locking hook (22); and when the locking tongue (40) is in the locked position whereby movement of the motor unit (25) to the open position slides the locking tongue (40) to engage the locking slot (51) such that the movement of the handle (30) is blocked.
  • the locking tongue (40) has a snap-fitted attachable locking head (41) and a carrier (43) operatively connected to the motor unit (25).
  • This cylindrically shaped locking head (41) has a U-shaped engagement groove (411) arranged to engage with an engagement protrusion (431) formed on the carrier (43).
  • the locking head (41) is shaped and dimensioned with respect to the cylindrically shaped locking slot (51) and perfectly fits in the locking slot (51) when the locking tongue (40) is pushed horizontally.
  • the main body (20) has a substantially rectangular cross-section and has a raised embossed housing portion to house the handle (30) and the locking mechanism.
  • the main body (20) is, preferably, equipped with bolts and nuts at each corner and also includes a back cover (21) covering the raised embossed housing portion of the main body (20).
  • the back cover (21) has an elevated support portion (211) in the middle of this back cover (21).
  • This support portion (211) can have a triangle cross-section with at least two guiding holes for pivotable attaching the locking hook (22) and the triggering member (24) wherein two fastening members (212) pass through the guiding holes and corresponding nuts (26) are used to fasten therein.
  • a bearing cover (23) is attached to one of the main lateral sides of the support portion (211) in which the locking hook (22) and the triggering member (24) are guided with a corresponding triggering spring unit (27).
  • Said bearing cover (23) has also suitable holes and engaging cylindrical tips for inserting into the corresponding holes of the support portion (211).
  • the triggering member (24) has two holes one of which is guided within the bearing cover (23) and the other hole of the triggering member (24) is used to attach between the arms (52) of the locking lever (50). In this way, the position of the locking hook (22) can be adjusted by bringing the position of the triggering member (24) to the desired position.
  • the proposed motor unit (25) has an outer body arranged to place within the embossed housing portion of the main body (20) and has a rotating operating rod (251) on which a spring (not shown) is placed and guided (25) to push the carrier (43) of the locking tongue (40).
  • the spring on the operating rod (251) is guided by a vertically arranged spring protrusion (252) formed on the operating rod (251).
  • One end of the spring abuts an inner wall of the carrier (43) and when the operating rod (251) is rotated, the spring is squeezed by the spring protrusion (252) which results in the carrier (43) being pushed.
  • the operating rod (251) can move along the horizontal direction (Y).
  • the locking hook (22) and the triggering member (24) together mechanically lock or unlock the latch assembly (10).
  • the handles (30), the attachment pin (28), and the locking lever (50) formed as one piece are connected to the triggering member (24) which is placed substantially in the middle of the latch assembly (10).
  • the triggering member (24) enables the locking hook (22) to be opened. Thanks to the triggering spring unit (27), the triggering member (24) always tries to stay in the neutral position. After it turns on, it returns to its original position. In order to bring the latch assembly (10) to the locked position, the locking hook (22) must be closed physically. This occurs when the door of a cabinet is physically closed. Referring to Fig.
