| Abstract: |
Locking tongs (10) have an upper arm (12) and a lower arm (14) pivotally mounted to each other for grasping items, such as food. A pivot pin (24) extends through aligned openings (27) in side flange extensions (20, 22) of arms (12 and 14) to connect arms (12 and 14) for pivotal movement. Torsion spring (28) urges arms (12, 14) apart. A channel-shape slidable locking member (32) has side flanges (36) with transversely aligned slots (40) therein receiving pin (24). Hook (39) has a hook portion (42) which may be easily gripped for sliding movement of channel-shaped locking member (32) between a locked position of arms (12, 14) shown in FIG. 1 and an open position of arms (12,14) shown in FIG. 4. Hook (39) is also utilized for hanging tongs (10) in a vertical position from a wall or rack.
