Definitions

  • the invention relates to a braking device for a cable drum, which is rotatably mounted on a fixed flange wall and can be driven in the winding direction by a spiral spring, in which braking device a braking element is provided which acts directly on the peripheral edge of one of the cable drum walls.
  • Such a braking device is known from DE-AS 2641 800.
  • a pivotably arranged support element which has two spring legs tapering in the winding direction of the cable drum.
  • the two spring legs lie on both sides of an axially outwardly formed edge formed on one cable drum wall.
  • the spring legs together with the edge form two wedge-shaped spaces, in each of which a hollow roller is arranged.
  • a disc pivoted in the winding direction by a leaf spring engages with two pins in the cavities of the rolls and also pulls them in the winding direction.
  • the hollow rollers are clamped between the tapered spring legs and the edge of the cable drum, so that the cable drum is prevented from rotating in the winding direction against the force of the spiral spring.
  • the disk can be pivoted against the force of the leaf spring by means of a release button.
  • the hollow rolls are also carried in the opposite direction and release the cable drum for a rotary movement in the winding direction.
  • the known braking device consists of a variety of elements, the assembly of which takes a lot of time.
  • the invention has for its object to provide a braking device which consists of only a few parts and is therefore easier and faster to assemble.
  • a braking element is provided with one end attached to the flange wall, which at least partially wraps around the peripheral edge and the other end is connected to a tension spring also attached to the flange wall.
  • a tension spring also attached to the flange wall.
  • a further simplification of the braking device is achieved according to one embodiment of the invention in that the band consists of an arcuate steel sheet strip on which an arcuate leaf spring is integrally formed.
  • the braking device thus consists of only a single component.
  • the leaf spring is curved radially outwards and with its end connected to the sheet steel strip rests on an axial projection of the flange wall and that a release button which can be pressed against it is also arranged above the curvature.
  • a cable drum 1 with a cable drum is designated, which is rotatably mounted on a journal 3 connected to a fixed flange wall 2.
  • a band 5 consisting of a sheet steel strip.
  • the band 5 has a loop 6, with which the band 5 is fastened to a first pin 7 connected to the flange wall 2.
  • the band 5 is integrally connected to an arcuate leaf spring 8.
  • the leaf spring 8 also has a loop 9 at its free end, with which it is attached to a second pin 10 connected to the flange wall 2.
  • the end 11 of the leaf spring 8 connected to the band 5 rests on an axial projection 12 provided on the flange wall 2.
  • a release button 13 is attached over the curvature of the leaf spring 8. The release button 13 is pushed back into its rest position either by the force of the leaf spring 8 or by an additionally provided coil spring 14.
  • the braking device described consists of only a single component, which by up put on the provided on the flange wall 2 pins 7 and 10 is already functional mounted.
