A guide device for at least one line, such as an electric line of a C-arm, has a rotatable first cylinder with a first cylindrical surface and a static second cylinder, adjoining the first cylinder in the axial direction and having a second cylindrical surface. A first guide element for guiding the line on the first and/or the second cylindrical surface, is disposed coaxially with respect to the first and the second cylinder and it is movable relative to the first and the second cylinder. The line can be wound up on the first and/or the second cylindrical surface or can be unwound therefrom depending on the movement of the first cylinder.

The proposed line guiding system for at least one heavy and/or rigid line, for example a power cable for shore-side power supply for a ship (alternative maritime power), has a winding device which is rotatable about an axis of rotation for coiling and uncoiling the line and a rotary guide for the line from a first point to a relatively rotatable second point. The rotary guide has a helical guiding course having first helical layers, in which the line is wound about the axis of rotation, and second helical layers, in which the line is wound in the opposite direction. A return curve connects the two helical layers. According to the invention, the rotary guide has a tubular support sleeve which is coaxial with respect to the axis of rotation and serves to support the helical layers radially outwards or radially inwards. Furthermore, a rotary decoupling structure is provided, by which helical layers supported on the support sleeve are decoupled from the winding device.

A waterproof storage system includes a protective housing member configured to mate with a handheld electronic device. The protective housing member includes at least one accessory station. The accessory station is configured to form between a surface of the protective housing member and a surface of at least one accessory item of the handheld electronic device. The protective housing member includes first and second housing parts. At least one sealing element positioned between the first and second housing parts provides a waterproof seal to protect the components of the waterproof storage system.

A retractable cord reel houses contacts that connect autonomously when the user aligns the spool to lock it from retracting. The spool and housing contains high quality, sensitive contacts for high speed data and other critical signals that engage when indexed by the user. The design is flexible for adaptation to a variety of applications and scalable based on cable type and length as well as the number of contacts required. The contacts are engaged when the user allows an indexing dog to engage a spool indexing housing causing the dog to shift and force a mating lever to make the electrical connection. Decoupling occurs instantly when the spool is slightly rotated by the user. The user's only action throughout the process is to pull the cable. Without this intentional action of the user, the spool, rotates freely and the contacts are not engaged.

A cable retractor includes a housing. A spool is disposed within the housing and is mechanically coupled to the housing and rotatable about an axis. A spring mechanism is operatively attached to the spool and is configured to urge the spool to rotate in a first rotational direction about the axis. An electricity operated rotation regulator is operatively attached to the spool and is configured to, when activated, prevent the spool from rotating in the first rotational direction.

The invention relates to a system (1) for transferring a magnetic link (2) between a first element and a second element rotatable relative to the first element, a first end of said link being adapted to be attached to the first element and a second end of the link being adapted to be attached to the second element, characterised in that it comprises: a first part (11, 13) adapted to be rigidly connected to the first element; a second part (21, 23) rotatable relative to the first part and adapted to be rigidly connected to the second element so as to be rotationally driven at the rotational speed of said second element; a third part (30, 31) rotatable relative to the first and second parts, a member for coupling (40, 45) the second and third parts, adapted to rotationally drive the third part at a speed equal to half the rotational speed of the second element, two sets of two coaxial ferromagnetic surfaces for winding the magnetic link (2), a first set comprising a first surface integral with the first part and a second surface integral with the third part, a second set comprising a third surface integral with the second part and a fourth surface integral with the third part.

A cable retractor is disclosed and includes a housing. A spool is disposed within the housing and is mechanically coupled to the housing and rotatable about an axis. A spring mechanism is operatively attached to the spool and is configured to urge the spool to rotate in a first rotational direction about the axis. An electrically operated rotation regulator is operatively attached to the spool and is configured to, when activated, prevent the spool from rotating in the first rotational direction.

A reel based closure device includes a housing, a tension member, a spool that is rotatably positioned within the housing, and a tightening component that is positioned axially above the spool and that is operably coupled therewith so that an operation of the tightening component causes the spool to rotate within the housing to wind the tension member about the spool. The reel based closure device also includes a coupling component that is separate from the tension member and that frictionally engages with a distal end of the tension member so that the coupling component is removably fixed to the tension member. The spool component includes a coupling feature within which the coupling component is positioned to attach the tension member to the spool.

A spool apparatus is described to include in one particular example a cable spool with a first cylindrical lip and a second cylindrical lip on an opposite side of the cable spool. A center of the spool includes a clutch bearing in the center of both the first cylindrical lip and the second cylindrical lip that provides a rotational axis for the cable spool to rotate around. The apparatus may also include a feed slot near the first cylindrical lip that provides a passage for cable to pass from the second cylindrical lip to the first cylindrical lip.

A cord reel assembly including a single, continuous cord having stationary and retractable segments, with the stationary segment including multiple connectors and sheath covering such connectors where the connectors twist and untwist relative to the sheath in response to the retract and extension of the retractable segment.
