Abstract

A merchandise display hook has a time delay mechanism for increasing the amount of time required to dispense items of merchandise from a display arm, while permitting bulk loading of the items of merchandise onto the display arm. The time delay mechanism includes a housing, a helix extending from the housing in a rearward direction, and a rotatable handle extending from the housing in a forward direction. Rotation of the handle causes the helix to rotate about the display arm to thereby dispense the items of merchandise from the display arm in the forward direction. The time delay mechanism further includes a lock mechanism having a secured position for attaching the time delay mechanism to the display arm and an unsecured position for allowing the time delay mechanism to be detached from the display arm to permit bulk loading. A first drive gear may be affixed to the handle that engages a reducing gear that in turn engages a second drive gear affixed to the helix so that the second drive gear turns the helix slower than the handle turns the first drive gear.

Claims (27)

1. A merchandise display hook for supporting and dispensing items of merchandise comprising:

a display arm having a first end for attachment to a display fixture and a second end extending in a forward direction away from the display fixture, the display arm comprising an elongate first rod extending from the first end to the second end and an elongate second rod extending from the first end to the second end and configured for supporting the items of merchandise on the display arm; and

a time delay mechanism configured to be removably attached to at least one of the first rod and the second rod adjacent the second end, the time delay mechanism comprising a helix that is at least partially disposed about both the first rod and the second rod;

wherein the helix is operable for increasing the amount of time required for dispensing the items of merchandise from the second rod at the second end of the display arm, while permitting bulk loading of the items of merchandise onto the second rod at the second end of the display arm.

2. A merchandise display hook according to claim 1 , wherein the time delay mechanism further comprises a housing and wherein the helix extends from the housing in a rearward direction towards the display fixture.

3. A merchandise display hook according to claim 1 , wherein the helix is disposed about both the first rod and the second rod at the second end of the display arm.

4. A merchandise display hook according to claim 1 , wherein the time delay mechanism further comprises a rotatable handle that is operable for rotating the helix about both the first rod and the second rod at the second end of the display arm.

5. A merchandise display hook for supporting and dispensing items of merchandise comprising:

a display arm having a first end for attachment to a display fixture and a second end extending in a forward direction away from the display fixture for supporting the items of merchandise on the display arm adjacent the second end; and

a time delay mechanism configured to be removably attached to the second end of the display arm;

wherein the time delay mechanism comprises a housing and a helix extending from the housing in a rearward direction towards the display fixture, the helix being at least partially disposed about the second end of the display arm;

wherein the time delay mechanism further comprises a rotatable handle extending from the housing in the forward direction and wherein the handle is operable for rotating the helix about the second end of the display arm;

wherein the time delay mechanism further comprises a first drive gear affixed to the handle and wherein the first drive gear is provided with a plurality of gear teeth that engage a plurality of gear teeth provided on a larger diameter portion of a reducing gear; and

wherein the time delay mechanism is operable for increasing the amount of time required for dispensing the items of merchandise from the second end of the display arm, while permitting bulk loading of the items of merchandise onto the second end of the display arm.

6. A merchandise display hook according to claim 5 , wherein the reducing gear comprises a smaller diameter portion opposite the larger diameter portion in the rearward direction that is provided with a plurality of gear teeth that engage a plurality of gear teeth provided on a second drive gear.

7. A merchandise display hook according to claim 6 , wherein the second drive gear is affixed to the helix so that rotation of the handle results in rotation of the helix about the second end of the display arm.

8. A merchandise display hook according to claim 7 , wherein the second drive gear has a larger diameter than the first drive gear so that the second drive gear turns the helix at a slower rate than the rate at which the handle turns the first drive gear.

9. A merchandise display hook for supporting and dispensing items of merchandise comprising:

a display arm having a first end for attachment to a display fixture and a second end extending in a forward direction away from the display fixture for supporting the items of merchandise on the display arm adjacent the second end; and

a time delay mechanism configured to be removably attached to the second end of the display arm; and

a lock mechanism disposed within the time delay mechanism, the lock mechanism having a secured position for attaching the time delay mechanism to the second end of the display arm and an unsecured position for allowing the time delay mechanism to be detached from the second end of the display arm,

wherein the lock mechanism further comprises a shuttle that is biased by a biasing force of a spring into engagement with a notch formed in the second end of the display arm in the secured position;

wherein at least a portion of the shuttle is made of a magnetically attractable material and wherein a magnetic force field attracts the portion of the shuttle against the biasing force of the spring from the secured position to the unsecured position; and

wherein the time delay mechanism is operable for increasing the amount of time required for dispensing the items of merchandise from the second end of the display arm, while permitting bulk loading of the items of merchandise onto the second end of the display arm.

10. A merchandise display hook according to claim 1 , further comprising a pusher device positioned medially between the display fixture and the time delay mechanism for moving the items of merchandise in the forward direction towards the second end of the display arm.

11. A merchandise display hook according to claim 1 , further comprising a locking base disposed on the display arm adjacent the first end, the locking base operable for locking the display arm to the display fixture to prevent removal of the display arm from the display fixture in a locked position and for allowing removal of the display arm from the display fixture in an unlocked position.

12. A merchandise display hook according to claim 1 , wherein the display arm comprises a lower rod for supporting the items of merchandise and an upper rod configured for receiving and removably attaching the time delay mechanism to the display arm.
