Abstract
Abstract A door window regulator for vertically moving a door window glass of a vehicle includes a guide member and a slider which is secured to the door window glass and guided by the guide member. A wire is stretched between upper and lower pulleys respectively disposed atthe upper and lower portions of the quide member and is connected at its intermediate portion to the door window glass. Thus, the door window glass is vertically moved by the driving force derived from a wire driving unit. A wire guide shoe projects from the guide member such as to contact the portion of the wire between the upper and lower pulleys, whereby the wire is bent between the upper and lower pulleys to thereby reduce the space occupied by this door window regulator.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
109 words
A door window regulator in which a slider guided by a guide member is secured to the lower portion of a door window glass, and a wire stretched between upper and lower pulleys respectively disposed at the upper and lower portions of said guide member is connected at its intermediate portion to said door window glass, characterized by comprising: a wire guide shoe projecting from said guide member and contacting the portion of said wire between said -upper and lower pulleys such as to limit the movement of said wire toward the inside of the compartment of a vehicle, thereby reducing the space occupied by said door window regulator.
Claim 2
Dependent Claim
109 words
A door window regulator in which a slider guided by a guide member is secured to the lower portion of a door window glass, and a wire stretched between upper and lower pulleys respectively disposed at the upper and lower portions of said guide member is connected at its intermediate portion to said door window glass, characterized by comprising: a wire guide shoe projecting from said guide member and contacting the portion of said wire between said -upper and lower pulleys such as to limit the movement of said wire toward the inside of the compartment of a vehicle, thereby reducing the space occupied by said door window regulator.
Claim 3
Dependent Claim
29 words
A door window regulator according to Claim 1, wherein the portion of said wire guide shoe where it contacts said wire has a circular surface projecting toward said wire.
Claim 4
Dependent Claim
35 words
A door window regulator according to Claim 1, wherein said guide shoe is disposed such as to project either forwardly or rearwardly of said guide member in terms of the longitudinal direction of said vehicle.
Claim 5
Dependent Claim
108 words
A door window regulator according to Claim 1, wherein the mounting portion of said wire where it is secured to said door window glass is disposed such as to pass on the side of said shoe which is closer to the outside of said vehicle when said glass is vertically moved, whereby, when said mounting portion reaches either the upper or lower end of said guide member, the intermediate portion of said wire abuts against said shoe and is thereby bent, and when said mounting portion is at a position intermediate between the upper and lower ends of said guide member, said wire is separated from said shoe.
Claim 6
Dependent Claim
25 words
A door window regulator according to Claim 1, wherein said shoe is secured to said guide-member through a shoe bracket projecting from said guide member.
Claim 7
Dependent Claim
28 words
A door window regulator according to Claim 5, wherein said shoe bracket is clamped by holders respectively projecting from both sides of the reverse surface of said shoe.
Claim 8
Dependent Claim
39 words
A door window regulator according to Claim 6, wherein a projection is provided on either one of the respective opposing surfaces of said shoe and said shoe bracket, thereby ensuring the connection between said shoe and said shoe bracket.
Claim 9
Dependent Claim
37 words
A door window regulator according to Claim 1, wherein said shoe has a stopper projecting from the side thereof such as to limit the movement of said wire in the direction orthogonal to the longitudinal direction thereof.
Claim 10
Dependent Claim
68 words
A door window regulator according to Claim 1, wherein said shoe has a stopper projecting from one of the sides thereof and a slanting surface formed on the other side, whereby it is possible for said wire which has been shifted in the direction orthogonal to the longitudinal direction thereof to smoothly return to its normal position, and said wire is prevented from interfering with any other elements.
Claim 11
Dependent Claim
32 words
A door window regulator according to Claim 1, wherein said shoe is formed from a synthetic resin so that the amount of friction occurring between said shoe and said wire is reduced.
