Locking device for product display hooks, showcases, cabinets, fixtures, and casework

A locking device comprising:

• an outer housing including an outer wall and a hollow cylindrical interior having a first longitudinal axis and an interior wall, the interior wall including a slot, the outer housing further including a first peg groove extending from a first side of the outer housing to a second side of the outer housing, the first side of the outer housing opposite to the second side of the outer housing, the first peg groove traversing the first longitudinal axis;
• a cylindrical shell including a projection, the cylindrical shell being at least partially disposed in the interior of the outer housing and moveable within the interior along the first longitudinal axis;
• 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;
• 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 to control the longitudinal motion of the cylindrical shell;
• and
• a pivoting member hingedly coupled to the outer housing by a hinging mechanism, the pivoting member including a second peg groove extending from a first side of the pivoting member to a second side of the pivoting member, the first side of the pivoting member opposite to the second side of the pivoting member, the pivoting member is pivoted about the hinging mechanism to achieve an open position relative to the outer housing or a closed position relative to the outer housing, wherein, in the closed position, the first peg groove is disposed adjacent to the second peg groove to form a channel extending from the first side of the outer housing and the first side of the pivoting member to the second side of the outer housing and the second side of the pivoting member,
• wherein the first peg groove is configured to receive a portion of a wire when the pivoting member is in the open position relative to the outer housing, the pivoting member is pivoted about the hinging mechanism to achieve the closed position relative to the outer housing enclosing the portion of the wire in the channel and the cylindrical shell is advanced along the first longitudinal axis such that the projection secures the pivoting member in the closed position to secure the wire in the channel.

A locking device comprising:

• a housing having a first end and a second end, the first end including a hollow cylindrical interior having a first longitudinal axis along the housing and an interior wall, the interior wall including a slot, the second end including a groove traversing the first longitudinal axis, the groove configured to receive at least a portion of a wire;
• a cylindrical shell including a projection, the cylindrical shell being at least partially disposed in the interior of the housing and moveable within the interior along the first longitudinal axis;
• 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;
• 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 to control the longitudinal motion of the cylindrical shell;
• and
• a pivoting member hingedly coupled to the second end of the housing by a hinging mechanism, wherein in an open position, the pivoting member is spaced away from the groove, and in a closed position, the pivoting member is pivoted about the hinging mechanism enclosing the portion of the wire in the groove,
• wherein when the cylindrical shell is advanced along the longitudinal axis toward the second end of the housing, the projection secures the pivoting member in the closed position.
