An end effector device includes a housing, a cable, and a winding mechanism. The cable includes at least one of lines that include a power supply line and a signal line. The winding mechanism is located inside the housing and configured to wind the cable. The winding mechanism includes a case, a reel, and a spiral spring. The reel is supported in the case and allowed to rotate and wind the cable. The spiral spring urges the reel in a retrieval direction of the cable pulled out of the reel.

A cable reel includes a spool to extend and retract a cable that includes a first conductor. The cable reel further includes a first connector that is connected with the spool and rotates in relation to the spool. The first connector includes a first contact that is connected to the first conductor of the cable. The cable reel further includes a second connector that does not rotate. The first connector and the second connector are mateable. The second connector includes a second contact that is connected to a second conductor. The first connector and the second connector automatically mate to make an electrical connection between the first conductor of the cable and the second conductor when the first connector and the second connector are aligned in a predetermined position and at least some length of cable has been extended.

Disclosed is a hooking device of a VR data cable, configured to hang the VR data cable, including a buffer, a hang assembly, and an adjustment assembly. The buffer is hung on a hook of a ceiling. The hang assembly is configured to hang the VR data cable. One end of the adjustment assembly is connected to the buffer, and the other end of the adjustment assembly is connected to the hang assembly, and the adjustment assembly adjusts a hang height of the VR data cable through elastic expansion and contraction.

The invention relates to a modular rotary feed-through (1, 2) for circular movements across a limited rotational angle of one or multiple lines such as cables, hoses, or the like between two connecting points (A, B) which are rotatable relative to one another about a rotational axis. Therein, the line(s) is/are guided in an uninterrupted manner, i.e., without slip rings, rotary couplings or the like. The rotary feed-through (1, 2) has a first winding core (11a, 11) which is rotatable about the rotational axis (R) and which has a first energy guide chain (12a, 12) which winds and unwinds in a spiraling manner, correspondingly to a planar spiral. According to the invention, at least one second winding core (11b, 11) is provided axially adjacent, coaxial and rotatable about the rotational axis (R) relative to the first winding core (11a, 11), which second winding core (11b, 11) is equipped with a second energy guide chain (12b, 12). During its rotation, the second winding core (11b, 11) winds and unwinds the second energy guide chain (12b, 12) in a spiraling manner, correspondingly to a planar spiral. Furthermore, according to the invention, a connection (17, 27) for the uninterrupted feed-through of the at least one line is provided between the first energy guide chain (12a, 12) and the second energy guide chain (12b, 12).

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.

There is disclosed a power drop assembly which includes a housing and a reel positioned and rotatable within it. Preferably, the device determines, not only whether power is available, but how much power is available. Preferably, the power drop assembly also contains a processor and non-transitory storage medium, so that user settings and profiles as well as settings and profiles for the power drop assembly can be stored and run. Additionally, the power drop assembly preferably contains a wireless transceiver which connects to a home Wi-Fi network and then to a cloud account, user profiles and settings, and settings and profiles for the power drop assembly can be saved on the cloud account. In this way multiple users can use the power drop assembly without contradicting instructions or resetting the power drop assembly every time it is used.

A hose or cable reel winder provides a handle for winding hose or cable onto a stationary reel and facilitates an orderly winding onto the reel. A guide is attached to an arm and the arm is free to rotate with respect to the stationary reel. The handle rotates in the guide allowing a user to wind hose or cable onto the stationary reel, and slides into and out of the guide to facilitate the orderly winding of the hose or cable onto the reel. The stationary reel does not require couplings between fixed source hoses or cables and a rotating reel, and allows releasing and collecting pairs or groups of hoses or cables.

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.
