A system of pay-in and pay-out function of a cooling system for an electric vehicle and a method of use is presented in this disclosure. The system may include a cooling cable, a cooling connector, wherein the cooling connector may include an actuator, a cable reel, and an idler drum. The cable reel may include a helical pattern where the cooling cable resides during the stowed configuration. The idler drum may be parallel to the cable reel.

A drum construction for an overhead garage door lift assembly includes a spiral groove comprised of three connected sections each having a distinct sequence of radii to facilitate raising and lowering of a multi-panel garage door mounted on a track in a manner which avoids undesirable surface impact of the door upon closing and enhances torque energy for lifting from the closed position.

The disclosure relates to a sleeve for fitting around a spooling drum: the sleeve comprises at least a groove for receiving a conveying element to be spooled around the drum, is made of flexible material and is configured so as to be able to take a first configuration in which the sleeve forms a flat sheet, the groove extending in a direction, called spooling direction, and a second configuration in which the sleeve forms a cylinder, with the groove is situated on an external face of the cylinder.

A refueling system, comprising a drum rotatatable to wind and unwind a hose, a carriage guiding the hose and lineally displaceable along a shaft parallel to the longitudinal direction of the drum so as to follow the movement of the hose along the drum. The shaft allows the displacement of the carriage along its length. A motor is coupled to the carriage and displaces the carriage along the shaft. A first position sensor communicates with the carriage to obtain its position. A second position sensor communicates with the drum to obtain the position of the hose. A control system is coupled to the first and the second sensor, to compare their obtained positions and to operate the motor.

The invention relates to a winding device (10) for a line (1), such as a cable or hose, including a stationary frame (11) and a winding drum (12), which is rotatably mounted on said frame and has an interior (12B). From the outside (12A) of the winding drum (12), the line can be wound or unwound. An inner rotary guide (18) in the interior (12B) guides the line (1) continuously from a fixed point (F) fixed with respect to the frame to a rotation point (R) on the winding drum (12) and defines a line course, having two opposite windings (18A, 18B) about the axis of rotation (A), and a rotatable deflection element (18C), in which the line changes over. According to the invention, the winding drum (12) has a first cut-out (15A) at a first end, on the side of the rotation point (R), which cut-out opens out axially and at an end face, and a retaining part (19B) at the other end, which retaining part is rotationally fixed to the frame, has a second cut-out (15B), which opens outward in a plane perpendicular to the axis of rotation (A). By virtue of the cut-outs (15A, 15B) in combination with the special rotary guide (18), the line (1) to be wound can be continuously routed without interruption and without rotational coupling or be subsequently attached, from the outside (12A) through the first cut-out (15A), in the inner rotary guide (18) and from the fixed point (F) of the rotary guide through the second cut-out (15B) or vice versa.

A tether guide operable through a wide range of tether/fleeting angles while causing minimal wear and having a reduced size compared to a levelwind wheel. The tether guide may include a series of rollers approximating the curved shape and radius of levelwind wheel. The tether guide may include downward facing guide wings matched to a curved roller profile, but flaring out to capture and guide tether into rollers. Sensors may be included on the tether guide to provide information about tether location, including whether the tether is engaged in the tether guide.

A system for carrying a tether guide, including a counter-balanced support system with two pivot points, where a first pivot allows the tether guide to travel up and down and the second pivot allows the tether guide to match the tether angle. Both pivots may be passive pivots. A shuttle that carries the tether guide may be electronically cammed to follow variable pitch helical grooves of a winch drum as the tether guide traverses across the drum length.

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 tether guide system operable through a wide range of tether/fleeting angles while causing minimal wear to the tether. The tether guide system may include a series of rollers arranged in a curved path. Also disclosed are tether guides with a sliding belt, a guide surface, or a guide wheel, all for use in the disclosed tether guide system.
