Abstract
A rotary cabinet with a self-latching and positioning rotor is provided with an improved latch mechanism. The latch is operated by a sliding hand actuator connected by links and levers to a latch member. To operate, the actuator is lifted to release the rotor. An air cylinder retards the return of the actuator and latch member to the latched position. While the rotor is released, the rotor is rotated to a desired position. The latch returns to the latched position and restrains the rotor. Materials can be stored in or retrieved from shelves on the rotor.
Claims26
A latching device for a rotor of a cabinet, comprising:
- an actuator;
- a generally vertically extending, vertically elongated link having a top end and a bottom end, said top end being operatively connected to the actuator;
- a movable latch adapted to engage between the cabinet and a rotor of the cabinet so as to restrain rotation thereof;
- a bias device for urging the latch toward its engaged position;
- and
- a linkage connected to the bottom end of the link and to the latch to translate motion of the actuator so as to cause disengagement of the latch, wherein the actuator is disposed above the linkage and the link extends substantially vertically between the linkage and the actuator.
In a rotary cabinet comprising:
- a cabinet;
- a rotor adapted for storage and rotatably mounted in the cabinet;
- and a base above which the rotor is mounted;
- a latch mechanism, comprising:
- a latch member mounted on the base, housed by the base and movable to a rotor engaging position so as to restrain movement of the rotor;
- a generally vertically extending, vertically elongated link operatively connected to the latch member;
- a bias device urging the latch member toward its rotor engaging position;
- and
- an actuator operatively connected to the latch member by the elongated link so as to disengage the latch member by movement of the actuator, the actuator being vertically spaced above the base.

- an actuator;
- a link operatively connected to the actuator;
- a movable latch adapted to engage between the cabinet and a rotor of the cabinet so as restrain rotation thereof;
- a bias device for urging the latch toward its engaged position;
- a linkage connected between the link and the latch to translate motion of the actuator so as to cause disengagement of the latch;
- and
- a delay mechanism for retarding return of the latch to its engaged position after disengagement.
