Description

[Detailed description of the invention] The present invention relates to a lifting device for a wheel opening glass.

In detail, the drive cable, which is connected by a large number of engaging pieces (tIs-shaped bodies), has a length of 1 m and 19 st J! Get a lifting device that allows you to lower it - after the glass has reached its lowering limit! l! Preventing the bell-shaped body of the drive cable from applying the force that would lower the glass, thereby preventing fatigue of the bell-shaped body, thereby preventing the breakage accident of the cable extension and prolonging its life. We aim to provide a completely new installation for vehicle headlights.

As a device for lifting and lowering the roof glass for a vehicle, there are a number of spherical O-engaging pieces b, b,...t with holes as shown in the irises/-.
We will discuss in more detail the known elevating device, which is formed by connecting II-shaped bodies 6 in a *bead-like shape, and is capable of elevating one galanus ε using a nine-way cable d. Then, the drive cable d#i
Among the vertical guide fv and the horizontal guide /A, flK is arranged so as to be slidable, and the engaging piece b%b,... is located between the horizontal guide /h and the vertical guide f. No. 1 is engaged with a sprocket wheel 5 rotatably disposed within housing I, and rotation of this sprocket wheel causes drive cable d to slide within guide f. The upper end of the drive cable d and the window glass are connected by a connector jK extending inwardly and outwardly through the vertical guide f, which is formed along the axial direction on one side of the vertical guide f.

However, when the sprocket wheel rotates forward or backward due to such a lifting device, the drive cable d, guide f, or housing go moves in the passage kO, and the window glass # moves accordingly. However, in such an elevating device, when the window glass is lowered by the single rotation force of the motor of the drive unit 1, the window glass remains at the point of descent and the glass tube remains closed. It is normal for the force that tries to lower the window glass to continue (applied), and after the window glass reaches the lowering limit point, the window glass is prevented from lowering further by a guide etc. Therefore, until the motor assembly stops, the drive cable dl
c A very strong force is added, and the cable dO
An excessive load will be applied to the engaging piece, k, . . . [the bell-shaped body to be connected]. However, the t1 bundle-like body is the engaging piece b%
h, -...-, the hole that was pierced by the shore, 6, ·°.

Although it can be inserted through the ... ) The bell-shaped body becomes fatigued due to turning, making it prone to breakage (IFI), and therefore, there is a problem that the durability is poor.

Therefore, in the present invention, after g*t passes to the descending member boundary point, K>
The force that causes the window glass tube to descend,

It prevents fatigue of the linear body, and it is KxJ @Ilt of the linear body.
This is intended to prevent and extend the service life of the drive cable, and it is designed to have a large number of flexible engaging pieces such as spherical and abacus bead shapes.
a drive cable connected in a shape, a cable guy for slidably guiding the drive cable in at least a certain straight section, and a rotating shaft (manually or by a suitable power source). The sprocket wheel engaged with the piece of the drive cable; an engagement piece on the lower side of the portion fixed to the drive cable of the connector from at least one of the holding pieces that are engaged with the sprocket wheel when the window glass reaches its lowering limit; and the connecting tool are integrally or integrally connected to each other.
-Characteristics Below, the vehicle window glass elevating device of the present invention will be explained in detail with reference to the accompanying drawings.

Figures m2 to #lφ show 11 configurations of the vehicle window glass elevating device of the present invention, in which l is fixed to the frame of the vehicle for the purpose of use.

The supports 1 and 01iK are parallel to each other and extend upward and downward 111. is formed, and the wall Jt % Jt □ Nakaseki IIK is formed with a circular fitting recess roller into which the fitting protrusion Jj of the coupling piece is fitted. In addition, a support groove core that extends in the front and rear views of the single unit and opens upward is formed on the support body K11, so that approximately the center of the lower edge of the support groove core K11L glass/F is placed on a fixed base. . Set 1: Connected platenco 0
By fitting the connecting piece here K1l1l*tC into the fitting lI@koj1 support J/lIDl1lsha concave 4, the connecting platen Co O and the support Co I are coupled and overlapped, thereby connecting the coupling tool/ I is formed.

Connecting platen 0 of connector /1 and a plurality of, for example, t engaging pieces /ja, /la, l! α

As mentioned above, the vehicle window glass of the present invention can be raised and lowered.
In m, from at least one of the retaining pieces engaged with the sprocket wheel when the window glass is suitable for the lowering limit point to the lower @O engaging piece of the connecting bracket, and the connecting bracket. [In addition, the two are connected as one. Therefore, in the case of lowering the window glass t''F, the blade that is applied to the window glass even after the window glass has reached the lowering limit point is connected from the sprocket to the connection bracket integrally or integrally with the connection plug. The force transmitted through the connecting piece does not act on the thin body.Therefore, there is a fear that the force applied to the window glass after it reaches its lowering limit will cause the linear body to become fatigued and break easily. Therefore, it is possible to increase the longevity of the drive cable.

Incidentally, the lifting device Ki of the present invention shown in #IJ diagram to 1st wAK

Also, there is a risk that the smooth movement of the connecting wire bracket 0 may be hindered. FIG. 5 and m4WJ show the deformation of the guide of the lifting device of the present invention which is designed to prevent dust from entering the guide.

30 is a straight guide formed by cutting a part of ll1l# of a cylindrical pipe body in the axial direction to form a notch 1lllIj111c, and the inner end fst along the axial direction is bent in opposite directions to form a retaining piece Jj, It is formed into an fA# shape and approximately an Ω-shape depending on the 3 pieces. Jj is a cover made of a material with appropriate elasticity, 70X
Engaging pieces 3≠, 3 are formed by folding back both side edges along the hand direction, and are formed so as to form a substantially mouth-like shape with a transverse surface shape. This cut is formed along the longitudinal direction approximately at the center, and is provided in a portion excluding the upper ms and lower end of the cover 3JO.

This cover JJ has its engagement piece 3-1Jμtm straight guide J
It is engaged with the vertical guide 30 so as to close the notch #I3 by the thread that engages with the engagement piece 3-1j- of No.0. The connecting piece 37 formed on the connecting bracket 36 in the guy FjO is connected to the cut J! of the cover 33 that closes the cutout @j/.
It is a cap that closes the upper 1l# opening of the guide 30.

In this way, in the 1 & straight guide 30, the 0 notch @j/ and the upper j1ml IO are closed by the cover 33 and the middle yap it, so there is no risk of dust entering inside the vertical guide j0. According to this modification, there is a risk that the smooth movement of the drive cable and connection bracket J4 within the vertical guide JO will be hindered.
