A mechanism for automatically regulating tension of wires employed in a window regulator comprising a drum being provided for rotational movement within said housing, and having a first side surface provided with a first ratchet teeth, a second side surface provided with a first engaging portion for engaging a first wire end, and a peripheral surface as winding surface; a ratchet plate being adjacent to said drum coaxially, and having a surface provided with a second ratchet teeth engaging said first ratchet teeth and a second engaging portion engaging a second wire end; a spiral spring having one end engaged with said ratchet plate and having the other end engaged with said housing, and urging said ratchet plate is such direction that said first ratchet teeth and said second ratchet teeth are moved idly; an elastic member axially urging said drum toward said ratchet plate; and a shaft for operating said drum to rotate by means of engaging with said drum. The mechanism can employ a spiral spring having a larger diameter, and therefore, functions of regulating tension of wires and of balancing the force for raising a window glass with the force for lowering the window glass operate smoothly.

A window regulator employing a flexible control cable as a transmission means, comprising a bracket secured to a window glass, an operating means and an inner cable connecting the bracket and the operating means through conduits, and both end portions of the inner cable being respectively wound up and off in the operating means to slidably move the bracket along a guide rail in order to perform an opening or closing action of the window glass, whereby a light, small and simple regulator is provided.

Window regulator

A guide rail for a window regulator which is light in weight and is high in rigidity, being formed from a hoop plate and having a double-bending portion which is raised at almost right angle with the hoop plate and in the longitudinal direction of the hoop plate. Furthermore, a slide-guide mechanism for a window regulator which is light and in which play is small when it is slidably moved, comprising the guide rail and a bracket which is slidably guided along the guide rail. The bracket has slide shoes arranged zigzag along the double-bending portion of the guide rail and provided with an oil groove on a side face coming into contact with the double-bending portion, and a guide shoe having a face to guide both side edges of the guide rail secondarily and a fitting member for securing a wire.

A wire-driving device for a window regulator comprising a first pulley secured to a shaft supported rotatably to a casing, a second pulley secured to the shaft so as to be rotatable and axially movable along the shaft, and a wire of which both end portions are wound round said first pulley and second pulley respectively in the opposite direction to each other, the wire being capable to transmit power when the shaft is rotated, and ratchet teeth being provided on each of facing side surfaces of the pulleys, whereby elongation of the wire is automatically absorbed when the shaft is rotated to wind and unwind the wire round the pulleys.

Automatic tension-adjusting mechanism for window regulators

A compact and thin wire-driving device for a window regulator which absorbs elongation of wire automatically, wherein both ends of a driving wire are wound round two pulleys arranged parallel, i.e. a first pulley and a second pulley, in the same direction; a first gear is secured coaxially to the first pulley; a second gear is adjacent coaxially to the second pulley through ratchet teeth; the first gear and second gear are meshed to each other; and, when the wire is wound up round the first pulley, a slack of the wire is wound up round the first pulley and the second pulley remains stopped.

Wire-driving device for window regulator

A mechanism for absorbing elongation of a wire in a power transmission device comprising two coaxial pulleys, i.e., ratchet pulley and winding pulley, winding both end portions of the wire respectively in the opposite direction; a ratchet roller connecting with the ratchet pulley by means of ratchet and engaging to the winding pulley, whereby the elongation of the wire can be absorbed by winding only one end portion of the elongated wire around either the ratchet pulley or the winding pulley.
