Definitions

  • the present invention relates to a handle lock assembly according to the preamble of the claim 1.
  • Handle lock assemblies of a conventional type have a construction in which: a main body of the assembly is fixedly mounted on a door of a box or container; a handle is pivoted to the main body so as to be pulled out forward and pushed back rearward relative to the main body.
  • a lock plug is also incorporated in the handle wherein the handle is pushed back rearward relative to the main body and held in its closed position in the main body.
  • the available space for mounting this type of vertical handle-operated lock assemblies can be limited. It may be necessary to reduce in thickness the handle lock assembly as a whole by reducing in thickness the handle and in-depth the main body.
  • EP2476825 A prior art publication in the technical field of the invention may be referred to as EP2476825 (A2 ), which discloses a lock mechanism comprising a main body accommodating a handle. Rotation of said handle activates longitudinal rods movable on a locking and unlocking direction with respective slots.
