Alois 1 i u s s i in Inzing (Tyrol, Austria) clamp for clamping objects,

For clamping objects such as each other To be glued pieces of wood, screw clamps have been used in many cases, i.e. clamps with one clamping jaws firmly on one leg of a U-shaped base body is arranged, while the second clamping jaw can be screwed to one in the second leg of this TJ-shaped body Screw bolt is seated. These known clamps have the disadvantage that the clamping strength of the "Ferkstück is limited by the opening of the U and on the other hand, those that the screwing in and out is always proportionate takes a lot of time.

Clamping clamps have also been proposed at which the sliding jaw slid along several flexible rods attached to the fixed jaw. For clamping of an object the two jaws had to be bent apart and the workpiece was then pushed through the leather effect of the flexible rods clamped. This clamp required a lot of force on the one hand, so that for larger clamping forces two operators were required for this clamp. On the other hand, there was the disadvantage that with prolonged use the rods remained permanently deformed, so that turning the jaws was then necessary.

The aim of the fire is to create a clamp which does not adhere to these disadvantages, and this is achieved in that the rigid rod has an essentially square cross-section and the movable jaw can be displaced along this rod with some play, so that the angle, which the 'movable jaw occupies in relation to the fixed jaw 4967,

occupies, something is changeable and thus a jamming of movable baking is made possible over a relatively large distance. By applying a blow to the The movable jaws can then be clamped to the rod, thereby ensuring that the workpieces are securely clamped achieve.

The new clamp has the advantage over screw clamps, which also use a clamping effect, that a screwing movement is not necessary.

In the drawing is an exemplary embodiment the new clamp shown sehematically u.zw. Fig. 1 is a partial travel side view, Fig. 2 is a section along the line II-II in Fig. 1 and

Fig. 3 shows the clamp with clamped workpieces and the type of clamping and releasing again.

At one end of a rod 1 made of square steel, the fixed jaw 2 is arranged at right angles to this. This can be generated, for example, in that one end of the square steel is bent by 90 ° by seam forging and, if necessary, forged a little flatter. The movable jaw 5 is displaceable along the rod 1. In the exemplary embodiment, this is formed from steel strip (see lig. 2) and its two halves are held together with rivets 5. The opening 6 in the clamping jaw 3, in particular on the surfaces 7 and 8 facing the fixed jaw, is kept somewhat larger than the rod 1. At its inner end, the movable jaw 3 has a projection 9 which is used for clamping If you clamp workpieces 10 and 11, such as for example boards, then you bring them with one outer side to rest against the fixed jaws 2 and then move the movable jaw 3 until its projection 9 is against the other outer side of the Workpieces come to rest. Then you hit with a hammer 12 in the direction 13 on the movable jaws 3 u.zw. As a result, this jaws around the projection 9> which essentially maintains its position as a result of the contact with the workpieces, a counterclockwise rotation until the edges 14 and 15 of the opening β are on the side walls of the Stan ge 1
