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.

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

The present disclosure discloses a hose telescopic device with a locking structure, including: a hose, a receiving assembly and a locking structure, wherein one end of the hose is received in the receiving assembly, and the other end of the hose passes through the receiving assembly and the locking structure successively, and the locking structure includes a locking seat, the locking seat being provided with several locking pawls having elasticity, the locking pawls being used for locking the hose, and the locking seat being sheathed with a locking piece used for tightening or loosening the locking pawls. The locking seat is sheathed with a locking piece for tightening or loosening the locking pawls, and the locking pawls lock the hose, to provide a hose telescopic device with a locking structure, which is convenient for locking the hose after drawing, and expands the scope of application for drawing hose.

A reel has a spool member on which the linear material is spooled, an electric motor that rotates the spool member, and a controller that controls the operation of the motor. The controller monitors an unwound length of the linear material based on sensed rotation of the spool member by one or more sensors. The controller causes the electric motor to wind the linear material around the spool member, for example, upon detection of a pulling force on the linear material over a pull distance within a predetermined range, but, for example, does not trigger the winding of the linear material if the pull distance is greater than the predetermined range. The controller can cause the electric motor to stop winding of the linear material upon detection of a force on the linear material that holds the linear material in place.

A self-opening bag includes front and real walls joined at their respective first and second side and bottom edges. The bag is folded at least once parallel to its side edges. At least one attaching feature is located on the outer surface of the bag adjacent the upper end and between the folded walls. The bag is releasably attached to a subsequent bag. The at least one attaching feature causes the bag to open as the bag is pulled from the subsequent bag. The once folded bag may be sealed at the bottom edges after folding to form a star-sealed bag bottom. The bags may be removably attached to each other at a perforation line and wound onto a compact roll for use with a bag dispenser. The bags may have an upper seam, a U-shaped cut and a pair of bag handles. The bags may be corona treated.

Apparatus and methods are disclosed related to spooling and unspooling linear material. Such apparatus and methods can assist the user in deploying and/or retracting linear material.

An apparatus for spooling wire including an inner flange assembly, wherein the inner flange assembly includes a first inner supporting wall and a second inner supporting wall, wherein the first inner supporting wall includes an inner locking hole. The apparatus including an outer flange assembly, wherein the inner flange assembly is capable of freely rotating relative to the outer flange assembly, and wherein the outer flange assembly includes a first outer supporting wall and a second outer supporting wall, wherein the first outer supporting wall includes an outer locking hole. The apparatus also including a locking plug for insertion into the inner and outer locking holes, wherein the inner flange assembly cannot freely rotate relative to the outer flange assembly when the locking plug is inserted into the inner and outer locking holes and wherein the locking plug, when inserted, extends between only one outer supporting wall and the adjacent inner supporting wall.

A safety leash comprises a wrist mount body, a cord supported by the wrist mount body, a biased engaged brake for braking the cord, and a brake release.

A spooling system for deploying cable, hose, and/or umbilical connections may include a drum, an air motor, a sheave having one or more sensor, and an electronic control unit coupled to an electro-pneumatic drive for controlling the system. The sensors may provide information to the electronic control unit, such as a measured line tension and/or a length of cable, hose or umbilical connection that has been deployed, and the information may be displayed on the electronic control unit. The electronic control unit also may allow an operator to rotate the reel, stop rotation of the reel, increase or decrease the speed of rotation of the reel, increase or decrease pressure and/or line tension, and/or select between a normal mode of operation and a tensioning mode of operation.

An elongate article holder with a flexible non-magnetic band, along with two terminal ends that may be removably secured to each other, is used to wrap around an elongate article or coils of the elongate article. In various exemplary embodiments, removable coupling of the two terminal ends may be provided by magnet(s), which may be substantially protected from environmental harm while simultaneously helping to achieve optimum magnetic closure strength by using tubular apertures/dimples which may run from a cavity housing the magnet to or near a mating surface of a respective terminal end. Further, the flexible non-magnetic band may have an integral closed loop for removably attaching to the elongate article, operating by passing a portion of the elongate article through a formed orifice that is formed from the integral closed loop.
