Definitions

  • the invention relates to a screw clamp with a guide rail made of steel, a longitudinally displaceable slide bracket carrying a threaded spindle with a tensioning cap and a fixed bracket obtained by bending and drop forging the guide rail, which in the region of its free end on the side facing the slide bracket and a pressure plate and opposite side has a slope which - seen in the side view transverse to the plane of movement of the slide bracket - forms an acute angle with the fixed bracket longitudinal direction, which opens in the direction of the guide rail.
  • the invention was based on the object to protect the all-steel screw clamps of the type mentioned on the market against tipping when they are set up together with the workpiece held by them in the manner described with the fixed brackets down or on a workbench or the like be put on.
  • This object can be achieved according to the invention by means of a protective cap which can be snapped onto the free end of the fixed bracket and is preferably in the form of a plastic injection-molded part and which, on its outside facing away from the sliding bracket, forms a supporting surface which projects beyond the highest point of the slope of the fixed bracket retrofit further, ie the solution according to the invention can also be applied to all-steel screw clamps which have already been produced.
  • the protective cap according to the invention thus takes on the task of the nose on the fixed bracket of the known malleable cast iron screw clamps, and the distance of the support surface from the clamping formed by the protective cap, measured in the clamping direction
  • the surface can be chosen to be of any size, so that the screw clamp can be securely held in any case. If it was mentioned above that the support surface protrudes beyond the slope of the fixed bracket, this means that the support surface, held in the tensioning direction, is at a greater distance from the pressure plate of the fixed bracket than any point of the slope of the fixed bracket.
  • the protective cap could snap into the rounding of the pressure plate facing the guide rail.
  • a stepped shoulder provided on the latter behind the pressure plate is used to hold the protective cap on the fixed bracket, the protective cap then being provided with a projection for snapping onto or behind this shoulder.
  • the protective cap according to the invention could also have the shape of a shoe that is open at the top.
  • a simpler plastic injection molding tool results if the protective cap is in the form of a closed quiver which surrounds the free end of the fixed bracket on all sides.
  • FIG. 1 shows the all-steel screw clamp 10 to be improved according to the invention, which comprises a guide rail 12, a fixed bracket 14 integral therewith, a slide bracket 16 which can be displaced along the guide rail and can be fixed on the guide rail in a known manner by tilting, and one with a Handle 18 and a pressure cap 20 provided threaded spindle 22.
  • the latter runs in a threaded bore of the slide bracket 16, the axis of which runs parallel to the longitudinal axis of the guide rail 12.
  • the slide bracket has an opening penetrated by the guide rail 12 and it is also designed as a forged part, like the fixed bracket 14 produced by bending and deforming the guide rail 12.
  • the latter has in the region of its free end uz on the side facing the pressure cap 20, a pressure plate 24 with an oval shape in the view from below, which, like a molded on the pressure plate, in the side view approximately triangular web 26 merges into the actual bracket 14.
  • the latter forms on its underside, together with the pressure plate 24, a shoulder 28 which has the shape of a step, but in principle could also be designed, for example, as a notch.
  • this protective cap has a base 34 which is adapted to the shape of the pressure plate 24 and which is provided at its end facing an opening 36 of the protective cap with a nose 38 or a differently shaped projection which engages behind the shoulder 28 when the protective cap 32 to has pushed onto the fixed bracket 14 as far as it will go.
  • the shape of the upper part of the protective cap 32 is adapted to the shape of the fixed bracket 14, ie it has a hollow rib 40, which is adapted to the web 26 in side view and in width, and finally has the protective cap 32 is a hollow hump 42, the upper side of which forms a support surface 44 which, according to the invention, projects beyond the upper edge 14a of the fixed bracket 14, as far as is necessary, in order to tilt the screw clamp in the direction of the arrow shown in FIG. 1 B to prevent.
  • the protective cap 32 can be designed such that the support surface 44 - according to FIG. 1 - is somewhat higher lies as the highest point of the fixed bracket 14.
  • the course of the support line 50 is therefore to be regarded as a special feature of the invention.
  • the protective cap according to the invention is also advantageous if the fixed bracket does not have the slope formed by the upper edge of the web 26, but rather the support surface formed by the protective cap simply gives the screw clamp set up such an angle between the upper bracket edge and the table top, that the screw clamp cannot tip over even with a clamped workpiece.
