A reeling device for the controlled coiling and uncoiling of a cable has a first end that is fixed and a second end that is movable relative to the first end. The cable is unbroken between its first and second ends. The reeling device includes first and second reels about which the cable is coiled. The first and second reels are coaxial. The first reel is fixed against rotation and axial movement, and the second reel is rotatable about the axis with such rotation causing axial movement of the second reel relative to the first reel.

The invention relates to a rotary guide (1) for guiding at least one line (2) between two points (3, 4), which can be rotated relative to each other, without interruptions. Two receiving parts (12, 14) for receiving a respective sub-section of two sub-sections (29, 31), which are to be wound about the common rotational axis (X) in opposite directions, of a line section (2a), which can be received in the rotary guide (1), can be rotated relative to each other about a rotational axis (X). A deflecting unit (16) supports a deflecting region (18), in which the line section (2a) of the line (2) changes over between the opposite sub-sections (29, 31) in order to deflect the line (2) to be guided from one receiving part (12, 14) to the other receiving part (12, 14) in the event of a relative rotation. Each of the receiving parts (12, 14) has a spiral-shaped receiving groove (20, 22) with a plurality of windings (24, 26) for receiving a line section (2a), said windings running about the common rotational axis (X) from a starting radius (r.sub.a) to a final radius (r.sub.e), wherein the windings (24, 26) lie on a plane perpendicular to the common rotational axis (X). The deflecting unit (16) has an active surface (33) which extends or can be adjusted radially between the starting radius (r.sub.a) and the final radius (r.sub.e) and which interacts with the receiving grooves (20, 22) in order to transfer the line section (2a) from the receiving groove (20, 22) of the one receiving part (12, 14) to the receiving groove (20, 22) of the other receiving part (12, 14) in the event of a relative rotation.

A length-adjustable cable device for wiring an aircraft cabin includes a cable and a cable drum with a cylindrical wall which is arranged around an axis of rotation and has an outwardly facing rolling-up surface. The first end of the cable is fastened to or arranged on the cable drum in such a manner that the first connection provided at the first end can be connected to a corresponding connection of another cable device. The cable is wound up onto the rolling-up surface in such a manner that it is unwound from the rolling-up surface by rotation of the cable drum about the axis of rotation thereof when the second end is moved away from the cable drum. The cable drum is configured for fastening to a cabin component of an aircraft cabin.

This invention concerns a line reeling device for reeling front and back lines of a kite. The device includes a reeling mechanism comprising a first reel and a second reel which are located in an enclosure and on which the front and back lines are, in use, wound respectively. The reels are arranged so that their rotation in one direction retracts the lines and their rotation in the other direction deploys the lines. The reeling mechanism further includes reel connecting means which is operable to cause the reels to rotate in harmony in one configuration and rotate independently in another configuration. The reeling mechanism also has a braking mechanism for controlling rotation of the reels and a control mechanism which is in connection with the braking mechanism. The control mechanism is operable between a first, locked position wherein rotation of the reels is obstructed and a second, released position wherein rotation of the reels is allowed.

A device for reeling in a cable and temporarily storing the cable is described. The device comprises first and second storage units, each comprising a cylindrical body for arranging the cable, as well as support means for carrying the cable from the source to cable seizing means of the second storage unit and further to the first storage unit. The second storage unit is rotatable around a rotation axis parallel to the cylinder longitudinal axis in a reeling direction. The storage units are arranged such that the second storage unit when rotating in the reeling direction can simultaneously reel in a part of the seized cable originating from the source and another part of the seized cable originating from the first storage unit. A method for reeling in the cable is also described. The device and method allow storing an increased amount of cable on a cable laying vessel for instance.

A retractable cord reel assembly comprises a reel rotatably supported within a frame or housing for rotation about an axis; a biasing spring engaged with the reel; and a single unitary electrically conductive cord having a distal end portion affixed to the housing, and a movable proximal end, wherein the cord is wound about the reel in a plurality of contiguous segments. The cord reel comprises separate coaxial cord-take-up and cord-storage compartments, having, in an initial cord configuration, a fixed-length segment of cord wound in a spiral around a hub in the cord-take-up compartment, and a segment comprising helical windings of the cord in the cord-storage compartment. The cord reel assembly described herein can be used in modern electronic data and power transmission applications without the significant losses of signal integrity or power, commonly associated with conventional cord reel assemblies.

A reel arrangement includes a main reel and a secondary reel which are mounted on a common reel axle. A winding diameter of the secondary reel is smaller than a winding diameter of the main reel. A line runs from a stationary first line end via a line loop to the secondary reel to be wound up and unwound there. The line is then routed to the main reel and secured to the main reel and/or the secondary reel. The secondary reel is winding spirally and the main reel is winding cylindrically. The line loop is under the influence of a tensioning force directed in opposition to a winding direction of the secondary reel and pulls on the line loop such as to always spirally wind the line. A weight body is connected to the line loop for displacement in longitudinal direction of the line to generate the tensioning force.
