Abstract
Locking devices that may be used with product display hooks, cabinets, and drawers are provided. A locking device according to one implementation comprising a housing and a shell. The housing includes an outer wall that defines an interior. The housing further includes a channel extending at least partially through the interior of the housing. The shell includes a projection. The shell is at least partially disposed within the interior of the housing and is moveable in a longitudinal direction within the interior of the housing. In an unlocked position, the projection is biased away from the first channel. In a locked position, the projection is maintained in the first channel.
Claims17
A locking device comprising:
- a housing including an outer wall defining a hollow interior, the hollow interior having a first longitudinal axis, the housing further including a first channel extending from at least one aperture in the outer wall to the interior of the housing, the first channel traversing the first longitudinal axis;
- an inner body mounted inside the interior of the housing, the inner body including an interior and a first slot;
- a cylindrical shell including a projection, the cylindrical shell being at least partially disposed in the interior of the inner body and moveable within the interior of the inner body along the first longitudinal axis relative to the inner body and housing;
- a cylinder plug including a key hole and an arced channel, the cylinder plug contained within the cylindrical shell and rotatable relative to the cylindrical shell when a proper key is inserted in the key hole and rotated;
- and
- a barrel pin disposed through a wall of the cylindrical shell, such that a first portion of the barrel pin projects toward the interior of the cylindrical shell into the arced channel to rotatably retain the cylinder plug in the cylindrical shell, and a second portion of the barrel pin projects toward the exterior of the cylindrical shell into the slot of the inner body to control the longitudinal motion of the cylindrical shell;
- wherein the first channel is configured to receive a wire to be locked, and wherein, in the locked position, the projection is extended into the first channel and maintained in the first channel to secure the wire.

A locking device comprising:
- a housing having an opening to an interior of the housing, the interior including a first longitudinal axis, the housing further including a first channel extending from at least one aperture in a wall of the housing to the interior of the housing;
- an inner body mounted inside the interior of the housing, the inner body including an interior and a first slot;
- a cylindrical shell including a projection, the cylindrical shell being disposed through the opening of the housing and into the interior of the inner body and moveable within the interior of the inner body along the first longitudinal axis relative to the inner body and housing;
- a cylinder plug including a key hole and an arced channel, the cylinder plug contained within the cylindrical shell and rotatable relative to the cylindrical shell when a proper key is inserted in the key hole and rotated;
- and
- a barrel pin disposed through a wall of the cylindrical shell, such that a first portion of the barrel pin projects toward the interior of the cylindrical shell into the arced channel to rotatably retain the cylinder plug in the cylindrical shell, and a second portion of the barrel pin projects toward the exterior of the cylindrical shell into the slot of the inner body to control the longitudinal motion of the cylindrical shell;
- wherein, in a locked position, the projection of the cylindrical shell is maintained in the first channel.
