ABSTRACT:
A pair of serving tongs (10) comprises two tong limbs (12, 14) which are connected to each other in a manner such that they can pivot relative to each other about a pivot axis (15) and are designed at their front ends (12a, 14a) for grasping food products, a spring (18) in order to prestress the tong limbs (12, 14) into an open position of the pair of serving tongs (10), and a locking mechanism (20) in order to lock the tong limbs (12, 14) counter to the prestress of the spring (18) in a closed position of the pair of serving tongs (10). In this case, the first tong limb (12) comprises an elongated hole (22) in which a locking pin (24) is moveably guided, and a locking cam (26) is provided on the second tong limb (14) and, in the locked closed position of the pair of serving tongs (10), comes into contact with the locking pin (24). A locking and an unlocking of the tong limbs (12, 14) takes place here by simple pivoting of the pair of serving tongs (10) into an essentially vertical position with the tong limbs close to each other. Furthermore, the locking mechanism (20) is arranged behind the pivot axis (15) of the tong limbs (12, 14), as viewed from a front end (12a, 14a) of the tong limbs (12, 14).
