The invention relates to a small vice, consisting of a screw clamp-like a table edge od. The like. Clampable bearing block and possibly also independent of this usable filing block, which faces the bearing block with one of its two clamping legs and hung in the bearing block by means of a holding part protruding from this clamping leg is, while the lower end of the same clamping leg by engagement in a recess of the bearing block the filing cock against movement out of the vertical plane of symmetry of the bearing block secures.

In a known small vice of this type is used as to hang the clasp in the Bearing block serving, of which one clamping leg of the filing block protruding holding part with a Button-head provided one end of the filet clamp screw used, on the other, the The end of the screw thread having the clamping nut can be screwed. This is the button head and the adjacent part that carries it and protrudes from the associated clasp leg of the clamping screw shaft inserted from above into a holding recess of the bearing block without special retaining means are provided for fixing the filing block on the bearing block. As a result, the Feilkloben, if a workpiece clamped in it is machined, inadequate on the Bearing block set so that there is no security against loosening of the filing clasp.

The object of the invention is to avoid this disadvantage. This is done with a small vice of the type described at the outset achieved according to the invention in that a holding part of the clasp is a Pin is provided which is at right angles to that formed by the two clamping legs of the filing block Clamping plane inserted through the clamping leg facing the bearing block and with its two protruding ends from above in two bearing grooves of the bearing block arranged at the same height is inserted, and that in the bearing block in its vertical plane of symmetry above or below a clamping device for the bearing slots, ζ. Β. a clamping screw or a clamping eccentric is arranged, by either the upper or the lower lever arm of the as a two-armed lever around the horizontal mounted pin swiveling clamping leg of the file block pressed to a small extent from the bearing block is, whereby the other lever arm of the same clamping leg is fixed accordingly to the bearing block is pressed.

In this embodiment of the subject invention with arrangement z. B. a fastening screw above or a fastening eccentric below the retaining pin bearing for the filing clamp with

ao nismäßig large distance from this storage is according to the resulting leverage, the immovable clamping leg of the clasp pressed against the bearing block with increased pressure. This leverage in connection With the favorable arrangement of the fixing pressure points on the bearing block this enables fast achievement of a very secure tight fit of the filing block on the bearing block, so that even when machining a workpiece clamped in the filing clamp does not yield or loosen in any direction of the filing block can be done on the bearing block.

In a further refinement of the subject matter of the invention, the one provided as the holding part of the filing block Pin at the same time as a means for axially fixing the clamping screw bolt or one to serve this parallel guide bolt of the filing clasp.

The drawing illustrates an embodiment of the invention, namely shows

F i g. 1 shows a view of a filing jaw clamping leg in the clamping direction,

Fig. 2 is a view of the contact side of the bearing block on which the filing block to form a Small vice is to be determined,

F i g. 3 shows the top view of the FIG. 2 bearing block shown,

F i g. 4 shows a side view of the entire small vise, with part of the bearing block shown in section is.

The filing clamp has two clamping legs S ₁ and S ₂ . The clamping jaw α (FIGS. 1 and 4) is formed on the clamping leg S _1. To attach the filing

clasp on the screw clamp-like ζ. B. at a table edge clamped bearing block d is inserted through the clamping leg J _{1 of} the filing block of the pin b , which is inserted with its two protruding ends in two at the same height bearing grooves / of the bearing block d. The pin b is expediently used at the same time as a means for axially fixing the tensioning screw bolt ο or a guide bolt m of the filing block that is arranged parallel to it.

The bearing grooves / are arranged at equal lateral distances from the vertical plane of symmetry of the bearing block d in ribs e projecting therefrom. In this plane of symmetry of the bearing block, the recess h (FIG. 2) is provided at its lower end, into which, as FIG. 4 shows that the lower part of the filing jaw clamping arm J ₁ engages, whereby it is secured against movement out of the plane of symmetry of the bearing block. Further, at the upper end of the bearing block d in the vertical plane of symmetry of the fastening screw ao Ic ₁ against the abutment surface i of the upper part of the Feilklobenschenkels A ₁ stored screwed.

Accordingly, four pressure and contact points g, f, f, h are provided for fixing the filing block on the bearing block, which are connected to one another in FIG.

To attach the filing block to the bearing block d , the clamping leg J _{1 of} the filing block is first hung with the protruding ends of the pin b into the bearing grooves / of the bearing block. Then the screw Ic ₁ or the eccentric k ₂ is rotated in the sense of the firm pressing of the filing clasp J ₁ against the bearing block d. As a result, the filing block is quickly and immovably attached to the bearing block.

Claims (2)

Patent claims: 1. Small vice, consisting of a screw clamp-like on a table edge or the like. 40 clampable bearing block and a filing block that can also be used independently of this, which has one of its two clamping legs facing the bearing block and is suspended in the bearing block by means of a holding part protruding from this clamping leg, while the lower end of the same clamping leg engages in a recess in the bearing block Feilkloben secures against movement out of the vertical plane of symmetry of the bearing block, characterized _{% r} that a pin (b) is provided as the holding part of the filing block, which is perpendicular to the clamping _{plane formed by the two clamping arms (J 1} , J ₂ ) of the filing block through the the bracket (d) facing the clamping leg (J ₁ ) inserted through and inserted with its two protruding ends from above in two bearing grooves arranged at the same height (/) of the bracket, and that in the bracket (d) in its vertical plane of symmetry above or below the Bearing grooves (/) a clamping device, e.g. B. a clamping screw (Jc ₁ ) or a clamping eccentric (Ic ₂ ) is arranged, through which either the upper or the lower lever arm of the two-armed lever around the horizontally mounted pin (b) pivotable clamping leg (J ₁ ) of the hawk to a small extent Dimension is pressed off the bearing block, whereby the other lever arm of the same clamping leg (j ") is pressed firmly against the bearing block. 2. Small vice according to claim 1, characterized in that the pin (b) provided as the holding part of the filing block also serves as a means for axially fixing the clamping screw bolt (ο) or a guide bolt (m) of the filing clamp arranged parallel to it.
