Definitions

  • the invention relates to a clamping device for self-locking tensioning and shortening of belts and the like. With a holding part and a displaceably mounted clamping part, which causes the free end of the belt to jam under tensile stress.
  • clamping devices are known in different embodiments. They generally consist of at least two individual clamping parts which are connected as a unit by the belt wrap.
  • the components provided as clamping parts build relatively high, so that, in particular in the case of clamped objects used in the stack, the actual clamping device projects excessively beyond the circumference of this stack and leads to damage to the adjacent stacked objects.
  • the tensioning parts are also designed to be relatively large in the direction of the belt to be tensioned, so that damage must also be expected on the circumferential surface to be tensioned.
  • the invention has now set itself the task of forming a particularly flat clamping device which preferably has the belt itself at least on the fixed clamping side and in a further area as an outer boundary and thus excludes a metallic damage surface.
  • the holding part and the clamping part are designed as loosely displaceable frames with cross bars and the fixed end of the belt comprises both frames, the transverse web of the clamping part enclosed thereby being wider than that of the holding part and this crossbar is assigned a second crossbar as the actual clamping web, which is arranged at a distance from its end face to the second web and this distance is designed to be less than the protrusion of the enclosed crossbar remaining against the pulling direction.
  • the holding part is equipped with a pulling device at its free end, which is not enclosed by the belt.
  • clamping device is shown in simplified form in a side view, from which the essential features emerge.
  • the clamping device consists of a holding part 1 and a clamping part 2, which are designed as loosely displaceable frames with crossbars 3-7.
  • the fixed belt end 8 comprises both frames, so that it is available as a closed unit.
  • the enclosed cross bar 5 of the clamping part 2 is wider than the web 8 of the holding part.
  • This web 5 is assigned a further web 6 on the clamping part 2 as the actual clamping device or as the actual clamping web, which is arranged with its end face 9 at a distance from the end face 10 of the transverse web 4. In the open state, this distance is less than the protrusion 1 of the enclosed cross bar 5 remaining against the pulling direction 11.
  • the transverse webs 3 and 5 are looped around by the belt end 18 fastened to one another.
  • the remaining belt end 13 runs around the web 4 of the holding part and then between the spacing surface of the webs 4 and 6, in order to finally be led away below the web 6 as a free end outside the actual area of the clamping device as the end of the pull.
  • a pulling device can be provided as a crosspiece 7 at the free end 15 of the holding part 1, which is equipped, for example, with a tab as a pulling strap, which also provides protection with regard to the direct contact of the clamping part with the stacked materials, for example, stacked materials stacking or bracing material.
  • the enclosed cross bar 5 of the clamping part has a bevel 16 on its end facing the holding part 1, which chamfer serves to unroll the corresponding cross bar 3 of the holding part 1 during the opening process.
  • the mutually facing clamping surfaces 9 and 10 of the transverse webs 4 and 6 are designed at an acute angle to the direction of tension 11 of the tension belt 13.
