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

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.

13. A locking device comprising:
-
an outer housing including an outer wall and a hollow cylindrical interior, the hollow cylindrical interior having a longitudinal axis, the outer housing further including an opening to the hollow cylindrical interior and a first slot, the first slot of the outer housing extending from at least one aperture in the outer wall to the interior of the outer housing and traversing the longitudinal axis; an inner body mounted inside the outer housing, the inner body including a first slot and a second slot; a shell having a projection aligned along the longitudinal axis and an outer wall including a first slot, the shell being at least partially disposed through the opening and into the hollow cylindrical interior of the outer housing and longitudinally moveable within the interior of the outer housing, wherein, in a locked position, the projection of the shell is maintained in the first slot of the outer housing; a cylinder plug including a key hole, tumblers, and an arced channel, the cylinder plug contained within the shell and rotatable relative to the shell when a proper key is inserted in the key hole and rotated; and a barrel pin disposed through a wall of the shell, such that a first portion of the barrel pin projects toward the interior of the shell into the arced channel to rotatably retain the cylinder plug in the shell, and a second portion of the barrel pin projects toward the exterior of the shell into the first slot of the inner body to control the longitudinal motion of the shell; a plunger locking bolt movably mounted through the first slot of the shell, such that, the plunger locking bolt moves perpendicularly to the longitudinal axis and the second slot of the inner body receives the plunger locking bolt to maintain the projection in the locked position; and a barrel spring at least partially contained within the hollow cylindrical interior of the outer housing, the barrel spring configured to bias the projection of the shell away from the first slot of the outer housing to an unlocked position. - View Dependent Claims (14, 15, 16)

17. A locking device comprising:
-
an outer housing including an outer wall and a hollow cylindrical interior, the hollow cylindrical interior having a longitudinal axis, the outer housing further including an opening to the hollow cylindrical interior and a first slot, the first slot of the outer housing extending from at least one aperture in the outer wall to the interior of the outer housing and traversing the longitudinal axis; an inner body mounted inside the outer housing, the inner body including a first slot and a second slot; a shell having a projection aligned along the longitudinal axis and an outer wall including a first slot, the shell being at least partially disposed through the opening and into the hollow cylindrical interior of the outer housing and longitudinally moveable within the interior of the outer housing, wherein, in a locked position, the projection of the shell is maintained in the first slot of the outer housing; a cylinder plug including a key hole, tumblers, an arced channel, and an engaging element, the cylinder plug contained within the shell and rotatable relative to the shell when a proper key is inserted in the key hole and rotated; a barrel pin disposed through a wall of the shell, such that a first portion of the barrel pin projects toward the interior of the shell into the arced channel to rotatably retain the cylinder plug in the shell, and a second portion of the barrel pin projects toward the exterior of the shell into the first slot of the inner body to control the longitudinal motion of the shell; a plunger locking bolt movably mounted through the first slot of the shell, such that, the plunger locking bolt moves perpendicularly to the longitudinal axis and the second slot of the inner body receives the plunger locking bolt to maintain the projection in the locked position, the plunger locking bolt further including an aperture, wherein the engaging element of the cylinder plug is disposed in the aperture of the plunger locking bolt, such that, when the cylinder plug is rotated the plunger locking bolt is drawn toward the interior of the shell in a direction perpendicular to the longitudinal axis to release the plunger locking bolt from the second slot of the inner body when in the locked position; and a barrel spring at least partially contained within the hollow cylindrical interior of the outer housing, the barrel spring configured to bias the projection of the shell away from the first slot of the outer housing to an unlocked position.
