A control device reduces an expansion speed of a covering material of a window covering system. The window covering system comprises the control device, the covering material and a weight member attached below the covering material to provide a weight force to the covering material. The control device comprises a driving module, a lifting module comprising a winding device configured to operate with the drive member and the covering material simultaneously, a damping module configured to operate with the winding device in only one direction for providing a damping force to the winding device selectively; wherein the damping force is provided to the winding device for reducing the expansion speed of the covering material when the winding device is rotated in the first direction; and wherein no damping force is provided to the winding device when the winding device is rotated in a second direction opposite to the first direction.

A device for rolling up and unrolling a floating mat with the floating mat having a first end, a second end, a first side, a second side, an upper surface and a bottom surface is disclosed. The device of the invention includes an elongated hollow cylinder having a first end, a second end and an outer surface. The cylinder has an elongated slot formed in the outer surface thereof which extends between the ends thereof. A mat retainer bar is positioned in the cylinder. One end of the mat extends inwardly through the slot in the cylinder and is secured to the mat retainer bar. End caps are secured to the ends of the cylinder and have a lever secured thereto. The mat may be rolled up on the cylinder or unrolled from the cylinder by rotating the cylinder by way of the levers.

A reel device is provided, including a shell body; a rotating shaft, movably and rotatably disposed in the shell body along an axial direction, the rotating shaft including a head section, an exterior circumferential face of the head section circumferentially having a plurality of engaging teeth circumferentially disposed thereon and extending radially; a ratchet assembly, including a first ratchet portion and a second ratchet portion meshed with the first ratchet portion, the first ratchet portion being fixed on the shell body, the second ratchet portion being rotatable relative to the first ratchet portion unidirectionally, the second ratchet portion comovably connected with the rotating shaft; a reel unit, rotatably disposed on the shell body for being connected to at least one rope, the reel unit having a meshed hole extending in the axial direction, the plurality of engaging teeth being radially detachably engaged with the meshed hole.

Described herein is a portable cleaning system comprising a reel around which one or more elongated flexible machine components such as roller chains may be wound to withdraw them from a machine, and means to clean and sanitize the components while they are supported on the reel. The reel may be rotatably supported on a cart. The apparatus further includes an enclosure for the reel, and means for introducing a fluid such as steam into the enclosure to clean and sanitize the components.

A window covering system comprises a shell, a weight member, a covering material positioned between the shell and the weight member, a control device. The covering material comprises at least one ladder, multiple slats corresponding to the at least one ladder, and at least one lifting cord, wherein the lifting cord is connected between the shell and the weight member. The control device comprises a driving module, a releasing module, and an operation module that are connected to each other. The ladder is connected to the operation module, and the lifting cord is connected to the driving module, such that the operation module drives the ladder to tilt the slats, at the same time, the releasing module is driven by the operation module to remove restriction to the driving module, hence descending the weight member.

A tightening system includes a housing and a spool situated within the housing. The spool is rotatable about an axis within the housing. An elongate tensioning element is rotatably linked to the spool and a tension control mechanism is operatively connected to the spool. The tension control mechanism is arranged to automatically move relative to the spool when tension in the tensioning element reaches a predetermined level, which, in turn, releases at least part of the tension in the tensioning element.

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 fastening device includes a case, a spool, a plurality of ratchet teeth, an incremental releasing set and a knob. The incremental releasing set includes a ratchet element and a swinging arm, the ratchet element includes a ratchet arm and a linking portion, the ratchet arm is selectively engaged with at least one of the ratchet teeth, and the swinging arm is abutted against the linking portion. The ratchet arm is engaged with at least one of the ratchet teeth to prohibit the spool from rotating in a releasing direction; as the knob is rotated in a tightening direction, the ratchet arm is disengaged from at least one of the ratchet teeth to allow the spool to tighten the lace; as the swinging arm is operated, the lace is incrementally released; as the knob is pulled up or rotated in the releasing direction, the lace is fully released.

Disclosed is a bidirectional spool apparatus (BSA) and method of use. The BSA comprises a spool apparatus having a plurality of spools, a plurality of cables, and an adjustment knob. When the BSA is in a first mode, rotation of the adjustment knob causes a corresponding rotation of a first spool in a tightening direction and a tightening of a first cable but allows a second cable to rotate substantially freely, and such that when the BSA is in a second mode, rotation of the adjustment knob causes a corresponding rotation of a second spool in a tightening direction and a tightening of a second cable but allows a first cable to rotate substantially freely. Switching of the BSA from a first mode to a second mode and vice versa is accomplished by pulling the adjustment knob out a distance and by pushing the adjustment knob in a distance.
