A lacing system configured to selectively adjust the size of an opening on an object and allow for the incremental release of the lace within the lacing system. The lacing system can have a reel comprising a housing, a spool supported by the housing, and a knob supported by the housing. The reel can be configured so that cable is gathered in the channel formed in the spool when the spool is rotated in a first direction relative to the housing, and so that cable can be incrementally released from the spool when the spool is rotated in a second direction relative to the housing. In some embodiments, the reel can include a rotation limiter which can be configured to prevent over-tightening of the lacing system and/or to prevent rotation past the substantially fully loosened state.

A system for dispensing a flexible hose includes a hose dispensing carousel having a frame, a spool support plate rotatably mounted to the frame and having a plurality of spool axles for rotatably supporting a plurality of spools of hose, and a lock adapted to fix a position of the spool support plate relative to the frame in a plurality of discrete positions. The system further includes a guide defining an opening adapted to receive a free end of a hose held on one of the plurality of spools. The guide defines at least one rotatable bearing surface positioned at the opening, and is adapted to guide the hose toward a tool for performing a manufacturing operation on the hose.

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.

A line-handling device is for letting out, winding up and locking a line. The line-handling device has: a first handle; a substantially flat reel which is rotatable relative to the first handle; a line-guiding part which is fixed relative to the first handle; a locking mechanism for locking the reel in a non-rotatable position; and an attachment element for a tautening device, the reel being displaceable relative to the first handle parallel to the rotational axis of the reel. A line-handling system is for suspending a line between two anchoring points and a method is for suspending a line between two anchoring points.

In accordance with example embodiments a hose reel system including a layout guide is provided.

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.

A control system and method for tensioning an active tether for a multirotor unmanned aerial system is provided. The control system includes a tensioning pulley and a tensioning spring. The tensioning spring is arranged to generate a variable tension force on the active tether. A transducer is connected adjacent to the tensioning spring to sense a linear displacement position of the tensioning pulley and to transmit a position signal to a controller. The position signal is proportional to the linear displacement position. A servomotor in communication with the controller receives a control signal from the controller in response to the position signal. The servomotor drives a cable reel. The cable reel is rotatably mounted in the frame for spooling the tether in response to rotation of the servomotor. The cable reel is rotated by the servomotor to maintain a predetermined tension on the tensioning spring.

The invention relates to a spool assembly for use to effectively manage cables and in particular cables for use as part of ultrasonic testing apparatus, The spool assembly allows the cables to be moved between a storage position in which at least part of the cables are located within the housing of the spool assembly and an extended position in which a greater portions of the cables is unwound and extended from the spool assembly. The spool assembly can be used in two modes of operation, a first mode to allow the cables to be wound onto the holder and a second mode in which the holder is biased to wind the cables into the storage position.

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.

The present invention relates to a device used to aid the rolling up and storage of a water mat or similar material.
