The magnetic tape container includes a core around which a magnetic tape is wound. The magnetic tape includes a non-magnetic support, and a magnetic layer including a ferromagnetic powder. A maximum value of a deviation of a center position of an average minimum region reference circle of a trajectory of one rotation drawn by the magnetic tape, in a case where the wound magnetic tape is drawn out from the core core is 100 μm or less for three points of the magnetic tape in a width direction.

A fastening device includes a case unit, a spool, a connecting unit, a knob and an engaging unit. The case unit includes a wall forming a receiving space, a partition separates the receiving space into an upper chamber and a lower chamber, a through hole located at the partition, and a base detachably connected to at least one part of the wall. The spool is located at the lower chamber. The knob is connected to the connecting unit. The engaging unit is located at the upper chamber. After the connecting unit is inserted into the spool, the through hole and the engaging unit to couple to the knob, the partition, the spool, the connecting unit, the knob and the engaging unit are connected integrally without being separated from each other while the base is separated from the at least one part of the wall.

An apparatus includes a housing, a rotatable spool disposed within the housing, a belt at least partially wound onto the spool, a motorized retraction mechanism disposed within the housing, coupled to the spool, and configured cause rotation of the spool in a first direction for winding the belt onto the spool, and a tensioning mechanism disposed within the housing, coupled to the spool, and configured to prevent over-rotation of the spool in a second direction opposite the first direction while the belt is being dispensed from the spool.

The invention discloses a locking structure for adjusting and/or locking a relative position between the first structure and the second structure, comprising: locking body, being movably connected to the first structure; a first member, extending along the length of the locking body and connected to the locking body; a guiding body disposed on the first member. The guiding body adjusts a relative position between the first structure and the second structure by moving along the guiding passage. The guiding body locks a relative position between the first structure and the second structure by entering a locking area of the guiding passage. The present invention further discloses a locking device and a coiling device using the locking structure. By providing a first member having a guiding body on the first structure and simultaneously providing a guiding passage on the second structure, when the first structure and the second structure are moved relatively, the guiding body is guided on the guiding passage. Different positions are used to adjust the relative position between the first structure and the second structure, and the locking of the specific position is completed, the locking effect is good and the reliability is high.

A retractable cable assembly in use with an electrical charger, power adapter, or other power supply. A cable wound on a spool disposed within a housing may be extracted by manually pulling on the cable or pressing of a release switch until the desired length of the cable is drawn. As the cable is drawn an engaged locking mechanism is used to keep the cable in place during and after extraction of the cable until which time retraction of the cable is desired. A retraction actuator disengages the locking mechanism, thereby freeing the cable and immediately retracting the cable within the housing.

A device tethering system is provided for securing a device to a source location as may be assisted by a tether. The device tethering system may include a retraction component, tether, pouch, belt, device mounting component, device aspect of the device mounting component, and/or tether aspect of the device mounting component. A method for securing a device to a source location using the device tethering system is also provided.

The invention relates to a winding device (30) for winding up and unwinding lines (50) of a stunt kite, paraglider or parachute (60) with at least three reels (11) for receiving at least one line (50) of the stunt kite, paraglider or parachute (60). According to the invention, at least two reels (11) have their own reel drive (14) for winding up and unwinding the line (50) taken up on the reel (11).

A portable retracting device for medical tubing management includes a housing. The housing includes a retractable cord disposed within the housing, wherein the retractable cord is configured to extend from a side of the housing. The device includes a first spring clamp configured to attach to clothing of an individual, a second spring clamp configured to clamp to the medical tube having a first diameter at a first location of the first medical tube, and a third spring clamp coupled to an end of the retractable cord configured to clamp the medical tube at a second location of the first medical tube to form a first loop in the first medical tube from the first location of the first medical tube to the second location of the first medical tube.

A pipeline inspection device including a stand, a drum rotatably supported by the stand, the drum including an opening in a front wall of the drum, a cable disposed at least partially within the drum, the cable including a camera disposed on a distal end of the cable, the camera and the cable configured to be directed into a conduit, a hub including a body at least partially insertable into the opening of the drum, the hub being electrically coupled to the cable when inserted into the opening, a wireless communication module housed within the hub, and a battery supported by the hub, the battery and the hub being removable from the drum as a single unit.

A retractable cable assembly in use with an electrical charger, power adapter, or other power supply. A cable wound on a spool disposed within a housing may be extracted by manually pulling on the cable or pressing of a release switch until the desired length of the cable is drawn. As the cable is drawn an engaged locking mechanism is used to keep the cable in place during and after extraction of the cable until which time retraction of the cable is desired. Rotation or twisting of at least a portion of the housing disengages the locking mechanism, thereby freeing the cable and immediately retracting the cable within the housing.
