【考案の詳細な説明】
本考案は手動或いは電動によるピニオンギヤ−の回動に
連動して昇降する自動車の窓ガラス昇降装置における特
にガイドパイプの構造の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the structure of a guide pipe in an automobile window glass lifting device that moves up and down in conjunction with the rotation of a manual or electric pinion gear.
従来の昇降装置におけるガイドパイプは第４図に図示す
るように、ガイドパイプ１３に同一平面内の長手方向に
沿って切欠き軌道溝１４を設けて断面円形状に構成して
いた。As shown in FIG. 4, the guide pipe in a conventional lifting device has a circular cross-section with a notched raceway groove 14 provided in the guide pipe 13 along the longitudinal direction within the same plane.
なお１１は撚り線からなるインナーワイヤーで、又１２
はインナーワイヤー１１の外周面に一定のピッチを有し
て螺旋状に連続捲き付けられたピニオンギヤ−と掛合し
て回動により移動する金属線材である。Note that 11 is an inner wire made of twisted wires, and 12
is a metal wire that moves by rotation while being engaged with a pinion gear that is continuously wound spirally at a constant pitch on the outer peripheral surface of the inner wire 11.

沿って設けた切欠き軌道溝１４に捩れ変形を生ぜしめ易
く、このような変形によって昇降操作に摺擦抵抗を増大
して比較的大きな回動力を必要とし、円滑作動を阻害す
る傾向にあった。Therefore, the circular cross-sectional shape increases the rubbing area between the inner circumferential surface and the outer circumferential surface of the metal wire 12 during sliding, and furthermore, when bending the guide pipe 13 as a product, the bent portion may be distorted or the same. The notched raceway grooves 14 provided along the longitudinal direction of the plane are likely to be torsionally deformed, and such deformation increases sliding resistance during lifting and lowering operations, requiring a relatively large rotational force and preventing smooth operation. tended to be inhibited.

面３′もしくは３′、３″として構成されている。The purpose of the present invention is to provide a guide pipe for a window glass lifting device that extremely effectively solves the problems of the prior art. The wire rod 2 is wound continuously in a spiral shape with a fixed pitch to engage a pinion gear that rotates manually or electrically, and the window glass attachment fixed to one end of the inner wire is attached to the leg part of the metal fitting 5. The guide pipe 3, which has a desired bent shape by engaging with the four notched raceway grooves in the same plane provided along the longitudinal direction and into which the inner wire is slidably inserted, has a circular cross section. At least part of the circular circumferential surface is configured as a flat surface 3' or 3', 3''.

かな回動力により円滑に作動できるものである。As described above, according to the present invention, at least a part of the circular circumferential surface of the guide pipe having an occluded circular cross section is formed on a flat surface.
' or 3' or 3'', the area of mutual sliding between the inner wire and the outer peripheral surface of the spiral metal wire 2 is reduced, and during bending into the desired shape as a product, In order to stabilize the seating in similar grooves provided on the opposing circumferential surfaces between a pair of bending rolls, not only the bending portions will not be distorted, but also the notches provided in the same plane along the longitudinal direction. It can be molded while easily preventing torsional deformation in the raceway groove 4, and the synergistic effect of these effects effectively reduces the sliding resistance during lifting and lowering operations, allowing smooth operation with a small rotational force.
