Definitions

  • the invention relates to a braking device for a cable drum, which is attached to a fixed Support part is rotatably mounted and can be driven in the winding direction by means of a spring drive, which braking device a acting on a wall part of the cable drum, by means of a release element has detachable braking element from its braking position.
  • Such a braking device is known from EP-B-0 090 974.
  • a circularly bent steel sheet strip is provided as the braking element, which rests on the peripheral edge of one of the cable drum walls and with its one End is attached to the supporting part carrying the cable drum.
  • At the other end is an as Tension spring molded onto the sheet steel strip, which is curved radially outwards is.
  • This leaf spring thus projects in the radial direction beyond the contour of the supporting part.
  • the leaf spring can be depressed using a release button. This leads to a Enlargement of the diameter of the steel sheet strip, which is thus somewhat from the peripheral edge of the lifts off the relevant cable drum and thereby the cable drum for a rotary movement releases in the winding direction.
  • Such a sheet steel strip is a relatively complex component to manufacture
  • the leaf spring protruding radially on the one hand leads to a constructional enlargement of the cable drum and, on the other hand, harbors one that is not installed in an additional housing Cable drum risk of injury.
  • the invention has for its object to provide a braking device of the generic type to further develop that these are carried out with structurally simple components can be and also a risk of injury from exposed parts of the braking device is avoided.
  • the object is achieved according to the invention in that the braking element from one with respect to the winding direction of the cable drum above its axis of rotation with one end on the side of the support part facing the cable drum on this supported, pivotable blocking member, which is in its blocking position with his other end on the inner circumference of an axially protruding on the corresponding flange wall the cable drum arranged braking edge rests, the blocking member in its length is dimensioned so that when the blocking member is pivoted from its other end circular arc described with the circular arc of the inner circumference of the braking edge cuts.
  • Such a blocking member can have a particularly simple structural design, for example have a straight-line contour. Because the blocking element is arranged on the inside of the support part and within the contour of the braking edge lies, it is completely covered so that there is no longer any risk of injury.
  • the blocking effect of the blocking member can be further improved in that the inner circumference of the braking edge one of successive grid elevations and recesses existing detent is formed and that described by the other end of the blocking member Circular arc with the enveloping circle on which the recesses lie, intersects.
  • a pivotable storage of the blocking member is unnecessary in that the Blocking member is rod-shaped and by using its own elasticity the release element is pivotable from its blocking position.
  • a particularly simple attachment of the blocking member results from the fact that Blocking member with one end in a receiving pocket provided on the support part is plugged in.
  • a separate attachment of the blocking member is superfluous if it is in one piece is integrally formed on the support member.
  • the release force for releasing the blocking member from its blocking position is thereby kept small, that the release element in the area of the other end of the blocking member with this is coupled.
  • a particularly simple coupling of the release element to the blocking member is provided that a push-through opening is provided on the blocking member, into which there is a release element connected driver pin engages.
  • a cable drum 3 is rotatably mounted on this hub 2.
  • the cable drum 3 will driven by a spring drive 4 in the winding direction 21.
  • An unwanted winding up to prevent the cable 5, such cable drums are provided with a braking device.
  • this braking device has a blocking member 6 which with one end 7 inserted into a receiving pocket 24 provided on the supporting part 1 and is thus supported on the support part 1.
  • the braking device also includes one on the supporting part 1 adjacent flange wall 8 of the cable drum 3 axially protruding brake rim 9.
  • On the inner circumference of this braking edge 9 is one of locking depressions 10 and locking elevations 11 existing locking contour provided.
  • the blocking member 6 is rod-shaped and engages in the blocking position with its other free end 12 in one of the locking recesses 10 a.
  • the length of the blocking member 6 from its pivot axis 13 to its free end 12 is dimensioned so that the free end 12 when pivoting the blocking member 6 described arc 14 with a continuous course of the inner circumference of the Brake edge 9 with the circular arc 15 of this inner circumference or one on the inner circumference provided screening with the enveloping circle 16 on which the locking recesses 10 lie, cuts.
  • the structural arrangement of the blocking member 6 is such that it is in its rest or Starting position (see hatched representation of the blocking member 6 in Fig.1) with his free end 12 at the bottom of one of the locking recesses 10 or with continuous, i.e. smooth contours of the inner circumference of the braking edge 9 abuts against this inner circumference.
  • the blocking member 6 is associated with a displaceably arranged on the support member 1 release element 17.
  • the release element 17 is provided with a driver pin 18, which in one in the area of free end 12 engages on the blocking member 6 provided through opening 19.
  • By pressing down of the release element 17 becomes the blocking member 6 using its own elasticity in the unwinding direction of the cable 5 indicated by an arrow 20 from the cable drum 3 corresponding direction pivots and thus moves out of the recess 10 out (see the unshaded representation of the blocking member 6 in Fig.1). This is the blocking effect is removed and the spring drive 4 can the cable drum 3 in the Drive arrow 20 in opposite winding direction 21.
  • the blocking member 6 swivels on account of it Self elasticity returns to its rest position and comes back in with the grid Engagement so that the cable drum 3 is blocked again in the winding direction 21.
  • an additional spring element 22 is indicated, which the return movement of the blocking member 6 can support.
  • the blocking member 6 with respect to the winding direction 21 above the axis of rotation 23 arranged the cable drum 3 and its length is such that it with his free end 12 in the rest position in one of the locking recesses 10 or on the smooth inner circumference of the braking edge 9 rests, results from a rotary movement of the cable drum 3 in Winding direction 21 a wedge action between the blocking member 6 and the braking edge 9, prevented by the further rotary movement of the cable drum 3 in the winding direction 21 becomes.
  • the spring drive 4 can Drive cable drum 3 in winding direction 21.
  • the blocking member 6 is integrally formed on the supporting part 1 when it is manufactured, it is not required the corresponding assembly costs for the blocking member 6. Since the grid at Manufacture of the cable drum 3 can be provided directly on the brake rim 9, result no additional assembly costs. When attaching the cable drum 3 on the support part 1, the braking device is created at the same time without any additional Activities.
