Abstract
An interlock system of a cabinet having two or more drawers includes an interlock swivel associated with a lock mechanism for each drawer. Each drawer includes a drawer pin movable along with the respective drawer and the interlock swivel is mounted so as to be movable between first and second positions. The interlock swivel comprises a pin capture slot, and the interlock swivel is constructed and arranged to be in the first position with the drawer pin of a respective one of the drawers disposed within the pin capture slot when the respective drawer is in the closed position. The interlock swivel is configured so that the drawer pin will enter the pin capture slot when the drawer is closed, even if the drawer pin is not aligned with the pin capture slot, to avoid a jam of the interlock swivel.

An interlock swivel for an interlock system of a cabinet having two or more drawers, each drawer being movable between a closed position and an open position, and each drawer including a drawer pin movable with the respective drawer, wherein the interlock swivel is mounted with respect to the cabinet so as to be movable between a first position and a second position, and wherein the interlock swivel comprises:
- a first leg;
- and
- a second leg spaced apart from the first leg to define an open-ended pin capture slot between the first leg and the second leg, wherein the interlock swivel is constructed and arranged to be in the first position with the drawer pin of a respective one of the two or more drawers disposed within the pin capture slot when the respective drawer is in the closed position, and wherein movement of the respective drawer from the closed position to the open position causes the drawer pin to engage the first leg and cause the interlock swivel to move from the first position to the second position, and wherein the first leg includes an end surface oriented at an obtuse angle with respect to a side of the first leg forming one side of the pin capture slot, so that if the drawer pin contacts the end surface of the first leg of the interlock swivel disposed in the second position as the respective drawer is moved from the open position to the closed position, inter-engagement between the drawer pin and the end surface will cause the interlock swivel to deflect to enable the drawer pin to enter the pin capture slot so that continued movement of the respective drawer to the closed position will return the interlock swivel to the first position with the drawer pin of the respective drawer disposed in the pin capture slot.
An interlock swivel for an interlock system of a cabinet having two or more drawers, each drawer being movable along a drawer axis between a closed position and an open position, and each drawer including a drawer pin movable with the respective drawer, wherein the interlock swivel is mounted with respect to the cabinet so as to be movable between a first position and a second position, and wherein the interlock swivel comprises:
- a first leg;
- and
- a second leg spaced apart from the first leg to define an open-ended pin capture slot between the first leg and the second leg, wherein the interlock swivel is constructed and arranged to be in the first position with the drawer pin of a respective one of the two or more drawers disposed within the pin capture slot when the respective drawer is in the closed position, and wherein movement of the respective drawer from the closed position to the open position causes the drawer pin to engage the first leg and cause the interlock swivel to move from the first position to the second position, and wherein the first leg includes an end surface oriented at an acute angle with respect to the drawer axis when the interlock swivel is in the second position, so that if the drawer pin contacts the end surface of the first leg of the interlock swivel disposed in the second position as the respective drawer is moved from the open position to the closed position, inter-engagement between the drawer pin and the end surface will cause the interlock swivel to deflect to enable the drawer pin to enter the pin capture slot so that continued movement of the respective drawer to the closed position will return the interlock swivel to the first position with the drawer pin of the respective drawer disposed in the pin capture slot.
