A cord winding mechanism for a blind cord with a first end fixed to a window blind includes a base, a cord winder rotatably mounted to the base, a cord guiding assembly mounted to the base, and an elastic press member mounted to the base. The cord winder defines an annular slot to wind the blind cord layer by layer. The cord guiding assembly is abutted against an unwound portion of the blind cord between the cord winder and the window blind. A second end of the blind cord is fixed to an end of the cord winder in the slot. The press member is elastically abutted against a portion of the blind cord just separate from the cord winder.

A sheet dispenser system having a roll of sheet material and a housing to receive the roll. The roll of sheet material comprises a first end portion incorporating a key, and the housing comprises a mounting portion arranged to support the first end portion of the roll and a support portion arranged to support a second end of the roll. The mounting portion comprises a tilting member pivotally coupled to the housing to define an operative position, in which the mounting portion and the support portion are aligned to support the roll in the housing, and a loading position, in which the mounting portion and the support portion are unaligned to inhibit support of the roll in the housing. The mounting portion comprises a block arrangement which is movable between a blocked condition, in which movement of the tilting member from the loading position to the operative position is inhibited, and an unblocked condition, in which movement of the tilting member from the loading position to the operative position is permitted. The mounting portion is arranged such that the roll is movable between an engaged condition, in which the key engages the mounting portion, and a disengaged condition, in which the key is disengaged from the mounting portion, such that, when the roll is moved from the disengaged to the engaged condition, the first end portion of the roll moves the block arrangement into the unblocked condition, thereby permitting movement of the tilting member from the loading position to the operative position.

A winder cable guard includes a generally flat plate that is attached to an inwardly facing surface of the outer support bearing in a winder mechanism. The plate is sized and configured to fit within and seal the clearance gap between the outer end of the winder drum and the outer support bearing. This prevents a cable being wound onto the winder drum from slipping or falling into the gap. The potential for jamming and/or breakage of the lift cable is thereby reduced.

Embodiments of the present invention are directed to recoilers, merchandise security systems, and methods for displaying and protecting an article of merchandise from theft. In one example, the merchandise security system includes a sensor configured to be secured to the article of merchandise and a base for removably supporting the sensor and the item of merchandise thereon. The system also includes a recoiler operably coupled to the sensor. The recoiler includes a rotatable member defining a helical recess. The system further includes a cable configured to connect to the sensor and to be unwound from and wound on the rotatable member as the cable is extended and retracted. The cable is configured to be extended from the recoiler in response to the sensor being lifted off of the base, and the cable is configured to be retracted into the recoiler in response to the sensor being moved to a seated position on the base. The helical recess is configured to at least partially receive the cable therein as the cable is wound on the rotatable member.

An elliptical reel is provided. The elliptical reel can include one or more longitudinal support members about a longitudinal axis of the reel and on which hose can be wound for transport. A cross section of the longitudinal support members that is perpendicular to the longitudinal axis defines an outline that has an elliptical shape.

A motorized reel apparatus suitable for endobronchial ultrasound bronchoscopy (EBUS) is presented. The present invention attaches to any suitable corresponding biopsy needle stylus. The motorized reel apparatus contains a reel housing, a spool drum, a spool spindle, a motor, and a controller. The reel housing contains wire outlet aperture. The wire outlet aperture traverses through the reel housing. The spool drum is connected within the reel housing. The spool spindle operatively engages along the spool drum, where the spool spindle can dispense a biopsy wire along the wire outlet aperture. The motor is rotatably engaged to the spool spindle. The controller is electrically connected to the motor, where the controller is configured to retract or deploy a biopsy wire along the wire outlet aperture.

A line fixing device includes a first housing, a second housing disposed to face the first housing, and a fixing member at least partially provided between the first housing and the second housing and configured to hold and fix a line. The fixing member includes a base portion, a column portion, protruding from a center of the base portion, around which the line is to be wound, and a plurality of latching protrusions disposed at predetermined intervals along an outer periphery of the base portion and configured to hold and fix a portion of the line which is not wound around the column portion. The latching protrusions have a tapered shape with a diameter gradually decreasing away from the base portion.
