Definitions

  • the invention relates to a clamp with two articulated clamping parts and one for adjusting the same serving spindle, which can be screwed into a nut part of one clamping part and is connected at one end to the other clamping part.
  • the object of the invention is to provide measures by which a quick rough adjustment of the tensioner parts and a fine adjustment of the same is made possible.
  • the spindle is guided in a part rotatable in the tensioner part, in which a button is slidably mounted transversely to the axis of the opening, which is provided with an opening penetrated by the spindle, the diameter of the openings of the rotatable part and the button is at most the same, preferably larger than the outer diameter of the spindle, and at least part of the opening wall of the rotatable part and / or the button with a nut thread or the like corresponding to the thread of the spindle. is provided.
  • the openings of the rotatable part and of the button are preferably provided with a threaded part at opposite positions of the axis of the button.
  • the button is expediently loaded by a spring which has the tendency to push the button out, so that the spindle is always in engagement with the nut part and the spindle only emerges from the nut thread when the button is pressed in against the force of the spring.
  • FIG. 1 shows the clamp in a diagrammatic representation
  • FIG. 2 shows a cross section of the spindle nut in the closed position
  • FIG. 3 shows a side view of the spindle nut according to FIG. 2
  • FIG. 4 shows a cross section of the spindle nut similar to FIG. 2 with the spindle released
  • Fig. 5 is a side view of the spindle nut
  • the ferrule according to the invention consists of an angled tensioner part 1 with a longer arm 1 'and a shorter arm 1 "and a second angled tensioner part 2, one arm 2' of which is articulated about a bolt 3 on the arm 1 'approximately in the center of the length thereof, while the second arm 2 "has a rotatable jaw 4 at its end, which interacts with a likewise rotatable jaw 5 at the end of the arm 1" of the fixed clamping part 1.
  • Each of the jaws has four receiving surfaces which have different profiles, for example cross-shaped, have round or other profiled millings that can be used as required.
  • a spindle 6 is provided which is rotatably but not longitudinally displaceable in a bolt 7 which is rotatably mounted at the angle of the pivotable tensioner part 2.
  • a rotatable part 8 in the form of a bolt g elarert, whose axis of rotation ⁇ arall to the axis of rotation of the bolt 7 and perpendicular to the upper or 2 to 5, which has a knob 9 which is guided in a bore 10 running transversely to the axis of rotation of the bolt 8 and transversely to the spindle axis and at its inner end is loaded by a spring 11, which is supported on the one hand on the bottom 12 of the bore 10 and on the other hand on the bottom of an end recess 13 of the button 9.
  • the button 9 which has the shape of a bolt, has, like the spindle nut 8, a bore 14 or 15, which bores have an inner diameter D which is larger or at most as large as the outer diameter d of the spindle. Both holes 14, 15 are penetrated by the spindle 6 and have diametrically opposite positions in the axial direction of the button 9 ie a nut thread 16, 16 'and 17, which, as will be described in more detail later, can be brought into engagement with the spindle 6 can, the nut thread 17 of the button is fed to the inner end thereof.
  • the button 9 As shown in FIG. 4, is pressed in by hand, as a result of which the SDindel 6 comes out of the reef of the threaded parts 16, 16 'and 17 ⁇ and can be rotated by pressure or tension Part 8 can be moved freely in the axial direction of the same.
  • the button 9 is released, as a result of which the spring 11 pushes it back into the position according to FIG. 2, so that the spindle 6 engages with the threaded parts 16, 16 'and 17, after which the fine adjustment can be made by turning the spindle with the handle 18.
  • the thread parts mentioned extend only over part of the wall of the bores 14, 15, so that there is sufficient engagement between the thread of the spindle 6 and the corresponding nut thread.

Abstract

La pince de serrage est constituée de deux parties (1, 2) coudées articulées qui présente à leurs extrémité se faisant face des éléments de serrage (4, 5). L'une des parties coudées (1) présente une tige (6) qui est vissée dans un écrou d'articulation (8), l'écrou (8) comporte un bouton (9) soumis à l'action d'un ressort (11). Par pression sur le bouton (9), il est possible de libérer la tige du pas de vis (16, 16') de l'écrou, ainsi la tige (6) peut être déplacée librement à travers l'écrou. La tige (6) est montée libre en rotation et articulée à une extrémité sur la seconde partie coudée (2).
