A security device includes a plurality of cables which are securable about an item of merchandise with a lockable cable-linking member and a cable-tightening mechanism each connected to the cables in a spaced apart manner. The cable-linking member may include a key member for unlocking the tightening mechanism. The tightening mechanism includes an internal spool and other internal members some of which are related to the locking and unlocking of the tightening mechanism. The tightening mechanism carries sense loops which typically include the cables and which if compromised actuate an onboard audible alarm. The device is configured to sound a security gate alarm upon passing through the gate and upon simply reaching a certain distance from the gate. The tightening mechanism may include a flip-up handle for rotating the spool to tighten the cable.

1. A security device comprising: a housing;a first cable;a spool within the housing which is rotatable about a vertical axis in a cable-tightening direction to wind the cable thereon and rotatable in an opposite cable-loosening direction to unwind the cable therefrom;a first internal member within the housing which is movable relative to the housing between a lowered locked position which prevents rotation of the spool in the cable-loosening direction and a raised unlocked position which allows rotation of the spool in the cable-loosening direction;a spring which biases the first internal member downwardly to the locked position so that an upward force is required to overcome the downward spring bias to move the first internal member from the locked position to the unlocked position; andan interference member within the housing which selectively prevents movement of the first internal member from the locked position to the unlocked position;wherein the spool is rotatable relative to the interference member. 2. The device of claim 1 further comprising an upwardly facing surface on the first internal member; and a downwardly facing surface on the interference member which abuts the upwardly facing surface to prevent upward movement of the first internal member. 3. The device of claim 1 further comprising a first opening formed in the first internal member; and wherein the interference member extends upwardly into the opening. 4. The device of claim 3 wherein the first internal member is rotatable about the vertical axis; and further comprising an arcuate edge which defines a portion of the first opening and is concentric about the vertical axis. 5. The device of claim 1 wherein the first internal member is rotatable relative to the housing and spool. 6. The device of claim 5 further comprising a second internal member which rotates with the spool relative to the housing about the vertical axis; and a sliding engagement between the first and second internal members during relative rotation between the first and second internal members. 7. The device of claim 5 further comprising an engaging member within the housing; and a second internal member within the housing which rotates with the spool relative to the housing about the vertical axis and which is movable relative to the spool and housing between a lowered engaging position in which the second internal member engages the engaging member to prevent rotation of the spool in the cable-loosening direction and a raised disengaged position in which the second internal member is disengaged from the engaging member to allow rotation of the spool in the cable-loosening direction; and wherein the second internal member is in the lowered engaged position when the first internal member is in the lowered locked position and in the raised disengaged position when the first internal member is in the raised unlocked position. 8. The device of claim 5 further comprising a first stop within the housing; and wherein the first internal member engages the first stop to limit rotation of the first internal member in a first direction. 9. The device of claim 8 further comprising a second stop within the housing; and wherein the first internal member engages the second stop to limit rotation of he first internal member in a second direction opposite the first direction. 10. The device of claim 1 further comprising a ramp within the housing; and a sliding engagement between the first internal member and ramp to translate rotational movement of the first internal member to upward movement of the first internal member. 11. The device of claim 1 further comprising a ramp within the housing; and a sliding engagement between the first internal member and ramp to translate downward movement of the first internal member to rotational movement of the first internal member. 12. The device of claim 1 wherein the first internal member is rotatable relative to the interference member between first and second positions; and further comprising a detent formed in one of the first internal member and interference member; and a detent projection on the other of the first internal member and interference member which is received in the detent in the first position to prevent the first internal member from inadvertently rotating out of the first position toward the second position. 13. The device of claim 1 further comprising an upwardly facing seating ledge within the housing; and wherein the first internal member in the unlocked position is seated on the seating ledge to prevent downward movement of the first internal member. 14. The device of claim 13 further comprising a ramp adjacent the seating ledge; and a sliding engagement between the first internal member and ramp during movement of the first internal member from the locked position to the unlocked position. 15. The device of claim 1 further comprising an annular space formed in the first internal member; and wherein the interference member is received within the annular space. 16. The device of claim 15 further comprising a second internal member within the housing which is below and rotates relative to the first internal member and housing; and wherein the interference member extends upwardly from below the second internal member into the annular space. 17. The device of claim 16 further comprising a slot formed in the second internal member; wherein the interference member extends upwardly from below the second internal member through the slot into the annular space. 18. The device of claim 1 further comprising a cavity formed in the spool having a bottom entrance opening; and wherein the first internal member comprises an annular ridge which is received within the cavity via the bottom entrance opening. 19. The device of claim 18 further comprising an annular space formed in the annular ridge having a bottom entrance opening; and wherein the interference member is received within the annular space via the bottom entrance opening of the annular space. 20.
