Definitions

  • Hook locks are typically used in settings where it is important to keep the unit value of the lock to a minimum. As such, simple manufacturing processes and efficiency of procedure are key in making successful hook locks.
  • An aim of the present invention is therefore to provide a hook lock mechanism that is simpler and more versatile than previous hook locks, while maintaining the same level of security and convenience.
  • the invention provides a hook lock mechanism, comprising a hook which pivots about an axis, characterized in that the hook is movable between at least (1) a position in which it is locked and can act as a dead bolt for a lock and (2) a position in which it is not locked but can act as a latch bolt for a lock.
  • the hook preferably comprises a latch ramp at its distal end.
  • the invention also provides a hook lock mechanism, comprising a hook which pivots about an axis, characterized in that the hook comprises a latch ramp at a distal end thereof.
  • the hook is preferably movable between at least a position in which it is locked and can act as a dead bolt for a lock and a position in which it is not locked but can act as a latch bolt for a lock. As shown in an example below, the hook may thus both latch in one position and lock in another.
  • the hook In its second position, the hook is free to move (preferably against a biaser) back into its first position without the need for e.g. a key. Movement into its third position preferably requires actuation of the mechanism with e.g. a key.
  • this position allows the gate to remain closed but not dead-locked; in other words, the gate is latched.
  • the gate can be opened from its latched position with a handle but without the need for a key. The gate can then swing closed with the hook in its second position because, advantageously, the hook has a latch ramp for passing over a strike plate fitted e.g. to the gate post.
  • the hook In its third position, the hook is unable to move back into its second position or its first position without actuation of the mechanism with e.g. a key.
  • this position allows the gate to remain dead-locked.
  • the invention thus provides a hook lock mechanism that is capable of both latch-locking and dead-locking, removing the need to have separate mechanisms for dead-locking and latch-locking a hook-based lock.
  • the lock is a gate lock.
  • the gate to which the lock is fitted is metal in composition. It is preferred that the gate to which the lock is fitted is a box section gate.
  • the gate to which the lock is fitted is the type which swings open and closed, such that a lateral impact is occasioned when the hook hits the strike plate.
  • the lock of the invention is not of the espagnolette (multi-point) type. These locks are most frequently used on patio doors and windows, where the materials are usually plastics or woods and it is easy to cut full-length portions therefrom. Espagnolette locks are not suitable for use on gates, especially box section metal gates.
  • the hook can latch when the gate is swung shut, when the hook laterally impacts a strike plate. That impact causes the hook to move substantially in the plane of the gate until the hook clears the strike plate whereupon it is biased back, e.g. by a spring, into a gate keeper.
  • the method is characterized in that the hook is responsible for providing both the latched position and the dead-locked position.
  • the invention hence provides a hook lock capable of both latch-locking and dead-locking a door or gate.
  • a cam (not shown) on the cylinder (10) moves a cam follower (28) which in turn rotates the hook (4) into a substantially horizontal, dead-locked position (not shown). In doing so, the latch return spring (22) is stretched to allow further projection of the hook (4).
  • the hook (4) is rotated approximately 90 degrees (from its vertical, retracted position) and hence projects out of the lock housing in a horizontal manner.
  • the invention hence provides a latching hook lock.
