Description

Holding tongs for laying concrete blocks and other large-format stones

Me invention relates to holding tongs for masonry Concrete blocks and other large format stones,

Such stones, which are relatively large in size and heavy, are currently being set by hand, although two-handed work is of course required. The stones are very rough and partly sharp-edged, ₅ so that constant manipulation is only possible with gloves, if scratches and abrasions are to be avoided. But working with gloves is cumbersome _? because they hinder the bricklayer and impair the sense of touch.

The invention is based on the object of a tool to create with which the concrete blocks and other large-sized stones "while lurking without difficulty and can be handled and set with great accuracy.

Mach the invention is to solve this problem a holding pliers proposed, which is characterized by two articulated pliers levers ₅ which have a substantially rectangular pliers mouth with the front lever sections and a substantially flat _s with the tip approximately in the rear, handle-bearing lever sections Area of the joint 1 form "

To form the essentially rectangular pliers jaws, the front lever sections are at right angles bent and provided with clamping jaws at the free end}, which when the holding forceps are closed on the stone side surfaces come to rest in the KLemmsitζ «, The distance between the practically parallel opposite lever sections of the jaws of the pliers, the dimensions "of the stones to be manipulated ..." are of course adapted. In order to avoid different holding tongs for different stone dimensions, a preferred

Preferred embodiment of the invention, characterized in that the joint of the pliers has a detachable G-elenkbolzenc, for example a hinge screw secured by lock nuts _s and that a series of hinge bores for the hinge pin is provided in the caliper levers to adjust the width of the pliers nipple. The pincer levers can therefore be plugged together as desired depending on the required opening width in the joint.

The jaws can be articulated connected to the tongs levers in principle _s to ensure regardless of the 3eweiligen mouth width surface contact of the clamping jaws on the stone side surfaces. However, if the opening width of the holding clamp in the manner described above the stone dimensions adaptable _s -.daß- so the opposite, the clamping jaw carrying the lever parts are practically parallel to each other, it is sufficient in an expedient embodiment. ■ ■ to fix the clamping jaws rigidly to the pliers lever ends and to provide them with a profile to increase friction on the IQ, emmflache *

The gate parts achieved by the invention consist essentially 'that a robust ₃ simple and
