FOOD HANDLING TONGS WITH SERRATED BLADE SLOTS Field of the Invention This invention relates to tongs utilized for gripping food products on a grill.

Background of the Invention Tongs for gripping food items on a grill including upper and lower plates connected to arms for grasping food objects therebetween. An example of such food handling tongs is 0 illustrated in U.S. Patent No. 4,002,365, issued January 11, 1977.

S A problem experienced in the prior art food handling tongs is that irregularly shaped food objects often'are squeezed out from between the plates by the action of the tongs. This problem is especially noticed when using the food handling tongs to grasp chicken parts or similar rounded skinned food objects.

Summary of the Invention The food handling tongs of this invention eliminates the problem experienced with the prior food handling tongs by providing 0 a pair of serrated slots in the upper and lower plates of the tongs. The projections or teeth formed by the serrated slots engage or bite into the food product when the two plates are squeezed together by the tong arms. Further, as in the previous food handling tongs, the plates are angled relative to the tongs' handles and intersect one another during the closing at other than a 90 degree angle such that the two plates slide relative to one another along the food product when squeezed to the closed position. The sliding action of the plates relative to one another also aid- in the biting action of the slot teeth in the plates.

Accordingly, it is an object of the invention to provide tongs for grasping and turning food items upon a grill.

Another object of this invention is to provide for tongs having upper and lower plates with serrated slots for grasping the food product.

Other objects for this invention will become apparent upon a reading of the invention's description taken with the accompanying drawings.

Description of the Preferred Embodiment The preferred embodiment herein described is not intended to be exhaustive or to limit the application to the precise form disclosed. Rather, it is chosen in order to enable others skilled in the art to utilize its teachings.

Referring now to the drawings, tongs 10 include a pair of arms 12 which are pivotally connected together by pin 14. One corresponding end of each arm 12 is formed into a handle 16 and the opposite end of each arm carries a plate 18. Pivotal movement of the atrms 12 about pin 14 causes plates 18 to shift between the generally superimposed food grasping or closed position shown in figures 1, 2, 4 and 5 and an open position such as that shown in figure 3.

Plates 18 are laterally offset when the tongs are in the open position as shoon in fig. 3. As the, tongs are closed to bring plates 18 together in a food grasping position, the upper plate 18 S shifts toward and laterally over the lowzr plate 18. This lateral displacement of the upper plate 18 relative to the lower plate 18 when the tongs are open enables the user of the tongs to more clearly see the food item 20 as the lower plate is being slid under the food item in preparation to be grasped and turned over or removed from a cooking surface. This movement of the upper plate 18 relative to the lower plate 18 is effected by having the pivot axis 24 defined by pin 14 of arms 12 angled relative to the plane of each of the plates. This angular relationship causes arms 12 when pivoted about pin 14 to move in a plane which intersects the plane of plates 18 at an other than 90 degree angle. As thus far described, tongs 10 of the present invention are substantially similar to those described in and claimed in U.S. Patent 4,002,365 incorporated herein by reference. A more thorough understanding of the basic operation of the tongs may be had by reference to the incorporated patent.

The tongs 10 of the present invention include a pair of longitudinal aligned serrated slots 26 formed in each plate 18.

The edge 27 of each slot 26 is formed into a plurality of projections or teeth 28. As illustrated in the figures and previously described, plates 18 in their open position are laterally offset in one direction relative to one another.

However, as further illustrated in the figures, plates 18 in their closed position are lateral offset in the opposite direction.

A Therefore, it should be understood that the plates during closing laterally shift relative to one another. When a food object is *600 presented between the plates 18 and the upper and lower plates are g o urged toward their closed position, the upper plate 18 slides across the upper surface of the food product. As the upper plate 18 slides laterally toward the lower plate 18, teeth 28 formed by serrated slots 26 bite into the food product to restrict movement of the food product as seen in Fig. 4. The biting of teeth 28 is enhanced by portions of the food product being squeezed through the slots 26 as the plates 18 are forced together. In the preferred embodiment, there are six protrusions or teeth 28 per slot for biting into the food product.

It is to be understood that the invention is not to be limited by the details above given, but may be modified within the scope of the appended claims.
