Clamping device for immobilising an object on a support table
Abstract
Abstract A CLAMPING DEVICE FOR IMMOBILISING AN OBJECT ON A TABLE HAS A CANTILEVER TYPE CLIP TRAVERSED BY A SCREW WHICH IS ANCHORED IN THE TABLE. AN ADJUSTABLE NUT BORNE COAXIALLY ON THE SCREW TO EXERT THRUST AGAINST THE CLIP CAN SLIDE ON THE SCREW AND COMPRISES A SLIDER ELEMENT TRANSVERSALLY MOVABLE IN A CYLINDRICAL BOX ELEMENT. THE SLIDER HAS A TAPPED CONCAVE SURFACE WHICH COOPERATES WITH THE SCREW THREAD IN A TRANSVERSALLY ADVANCED POSITION AND IS SPACED FROM THE SCREW THREAD IN A RETRACTED POSITION IN WHICH THE NUT CAN THEN SLIDE FREELY AXIALLY. THE SLIDER CAN THEN EFFECT A LIMITED AXIAL MOVEMENT IN THE BOX. THE TWO ELEMENTS HAVE COOPERATING CONICAL SURFACES TO LOCK AND UNLOCK THE TRANSVERSE POSITION OF THE SLIDER WHEN CLAMPING AND RELEASING RESPECTIVELY. A BETWEN BOX AND SLIDER URGES IT INTO ADVANCED POSITION. A NOSE OF THE SLIDER OPPOSITE THE CONCAVE TAPPING EXTENDS THROUGH A SLOT IN THE BOX FOR OPERATIONAL ACCESS. A SECOND SIMILAR. NUT RIGIDLY FIXED ON THE CLIP IS TRAVERSED BY A SECOND SCREW WHICH THRUSTS AGAINST THE TABLE TO INCREASE THE GRIP ON THE OBJECT.
