| Abstract: |
The invention relates to a simple method for producing tongs ( 1 ) and to a tong ( 1 ) comprising two arms ( 2 ) consisting of wooden material that can be elastically bent in relation to one another, said arms ( 2 ) being rigidly inserted into a head piece ( 3 ) at an angle to on another. To obtain an advantageous construction, each arm ( 2 ) is inserted into a respective groove of the wooden head piece ( 3 ), said V-shaped grooves being angled towards one another and both arms are connected to the head piece ( 3 ) in a permanent manner.

1. Field of the Invention
The invention refers to a tong comprising two converging arms consisting of elastically bendable wooden material and rigidly inserted into a head piece.
2. Description of the Prior Art
In order to seize food, tongs are known (DE 442 855 B) comprising two arms consisting of elastically bendable wooden material, which are inserted into a hollow conical head piece made of metal. Due to the form of the head piece and due to a cross strut at the open end of the cone surface area, the arms are rigidly inserted into the head piece at an angle to each other. However, a disadvantage about this tong is that the tong arms are easily detachable, since they fit only over small bearing surfaces inside the head piece. Repeated use leads soon to an increase of the axial play, so that the necessary rigid support is no longer given. In addition, the production of a conical head piece is complex and costly, in addition to which a cross strut needs to be introduced at the open end of the cone surface area.
Furthermore, tongs are known (U.S. Pat. No. 5,054,835 B) which have serving members held together with a head piece designed as a sleeve. The serving members are inserted into the head piece in parallel and this head piece holds the serving members together with a snap-fitting engagement. A disadvantage with using these tongs is, that with a reduction of the spring force of the snap-fitting engagement, a release of the serving members from the head piece may take place when holding food. In addition, the spring force of the snap-fitting engagement does not provide a rigid support of the serving members in the head piece, that gives a feeling of a sensitive holding of the food with the tong arms. Also, regenerating materials, like wooden materials, can be used for the head piece only at high production expenditure, which doesn't allow economical manufacturing of such tongs.
Other tongs (DE 75 02 395 U) consist of a head piece and two serving members. Thus a head piece is shown (FIG. 9), which has two serving members rigidly inserted at an angle to each other. For this purpose, two hole-like recesses, such as bores, pass through the whole head piece. In these recesses, the serving members are inserted. A disadvantage is, that the bending forces the serving members exert upon the head piece have to be taken up by the head piece parts lateral to the bores, which demands an increased expenditure of material. Also, the width of the head piece has to be larger than the width of the tong arms, therefore narrow tongs can't be produced with such a head piece. In addition, a rectangular recess is comparatively difficult to produce in a wooden head piece.

1. A tong comprising a head piece having a width and consisting of wooden material, the head piece having two grooves extending transversely therethrough in the direction of the width from one side of the head piece to the other, the grooves converging towards each other to form a V-shape, and two arms having the same width as the width of the head piece and consisting of wooden material elastically bendable in relation to one another, the arms having one end rigidly inserted in the grooves and connected to the head piece in a permanent manner to form converging arms.
