Compact winding device for a flexible line

A winding device (10) for winding and unwinding a flexible line (1) comprising:

• a frame (11) configured to be stationarily mounted;
• a hollow-cylindrical winding drum (12) mounted to the frame rotatably about an axis of rotation (A), the winding drum (12) forms an internal space and has an outside (12A) on to and from which a line can be wound and unwound;
• an inner rotary guide (18) for interruption-free guidance of the line (1) from a fixed point (F) which is fixed with respect to the frame to a rotary point (R) which is rotationally fixed to the winding drum (12) and is relatively rotatable about the axis of rotation with respect to the fixed point, and
• wherein the rotary guide between the fixed point and the rotary point predetermines a line path with two oppositely directed windings (18A, 18B) with a first winding direction about the axis of rotation (A), a direction-changing means (18C) which is rotatable about the axis of rotation and in which the line is changed over from the one winding (18A) into the other winding (18B) and a second winding direction in opposite relationship to the first winding direction;
• wherein the inner rotary guide (18) is accommodated at least predominantly in the internal space (12B) of the winding drum (12);
• wherein the winding drum (12) includes a first opening (15A) at a first end, on the side of which the rotary point (R) of the inner rotary guide (18) is provided, which opening (15A) opens out at the first end in the axial direction with respect to the axis of rotation (A), and that provided at the opposite second end is a holding portion (19B) which is non-rotatably connected to the frame and which has a second opening (15B) which opens outwardly in a radial plane perpendicularly to the axis of rotation (A) so that a line (1) to be wound can be laid from the outside through the first opening to the rotary point (R) in the inner rotary guide, in the inner rotary guide and from the fixed point (F) thereof through the second opening and vice-versa.
