  • the forces to be applied are towards the end of the clamping process extraordinarily high, so that taking into account the location of the fitter appearing on a ladder and there are considerable accidents Forces must be applied.
  • a tensioning device with the features mentioned above is already from the US 3,921,761 known. Instead of a device with which the chuck in more or less difficult handling in any case with regard to the to be applied Clamping force is only operated by hand, this allows known Formation of the clamping device with a worm gear, the output side Coupling to the chuck of a torsion spring to be tensioned and its drive-side connection option to a motor-driven Tools such as hand drills are only used to operate this tool Required actuation with only one hand and without the torque for tensioning the spring only by manual actuation have to.
  • the invention has for its object a tensioning device of the beginning to provide the type mentioned, the tensioning of the torsion spring device for the fitter less dangerous and with less manual operation allowed.
  • the worm gear is self-locking trained, i.e. when decoupling the hand tools from the gear the tensioned spring does not restrict the gearbox as far as the drive member move. This also simplifies handling for the clamping process or an interruption of the tensioning process, intended or by Slipping of the hand tools does not lead to a return of the spring tension.
  • the transmission gear consists of one Worm gear with a to the chuck or the taper of the for tensioning the spring end to be rotated relative to the shaft connected worm wheel and a worm engaging in it as Drive member, which is held rotatably in a clamping housing for the clamping process can be connected to the hand tools at one of its two shaft ends.

  • a connecting body in realize axial longitudinal median plane, forming a connecting body, the one with the protruding perpendicular to the central plane, in the assembled state in pins engaging diametrically opposite radial bores is provided and after joining the two half-shells the output member of the gear, in particular the worm wheel.
  • the clamping housing or connection body With multi-part training of the clamping housing or connection body must be due to the uniform Ensure the circumferential course of the worm wheel be worn that its configuration also taking into account the Rotation relative to the shaft is ensured, for example, what one achieved by distance-securing adapter sleeves, which are in aligned holes in the intervene several, in particular two, parts to be connected and by Bolts of corresponding screw connections are penetrated.
  • the tensioning housing together with the, in particular, approximately quarter-circle-shaped, hollow-throat gear formation of the worm wheel on the shaft applied state a the gear engagement between worm and worm wheel securing lock against axial relative movements, in particular by a provided on the clamping housing projection on a shoulder or in a Groove that engages in the quarter-circle toothing of the worm wheel axially facing area of the worm wheel or chuck unit and worm wheel or the connecting body.
  • the at least one torsion spring device mentioned here which is used for weight compensation a door leaf with a vertical component is used, is in conventionally by a correspondingly encompassing the shaft with its coils strong torsion spring formed. There are of these torsion springs on a wave two or more. These individual torsion springs can also by bundles of parallel, weaker torsion springs be formed, which are coupled via a planetary gear. Depending on Installation conditions and design can actuate the drive element, in particular a worm with shaft sections provided on both end faces, be desirable from both axial directions of the drive member, which is why a corresponding accessibility on both sides for the connection of the hand tools is preferred.
  • the figures all show a section of a shaft 1, as is known in the art Way for the weight compensation and / or the drive of door leaves with vertical Motion component is used, i.e. for single-leaf overhead doors, Lifting gates and in particular overhead or sectional gates; basically Such a shaft can also be used in the area of a winding shaft for roller doors.
  • cable drums are on both ends of the shaft provided, the end facing away from these windable and unwound ropes are attached to the door leaf and thus create a gear connection the movement of the door leaf in an accompanying rotational movement of the shaft implement; these facilities are generally known.
  • this high-speed transmission 8 is a self-locking, single-stage worm gear, so that the drive member of the Worm 10 and the output member corresponds to the worm wheel 9, the latter arranged coaxially to the chuck and connected to it so that it cannot rotate is.
