Description

DETAILED DESCRIPTION OF THE INVENTION The invention of Jin relates to a lifting guide device in a lifting device for a windshield for a vehicle.

As a lifting device for windshields of passenger vehicles, automobiles, etc.
In addition to the nine-arm type using the Risik mechanism, various mechanisms have been proposed such as the Goldewire type, tape type, and projection rack type. It is suitable for elevating devices such as the Goldia type, Q1 type, and projection rack type, which have an elevating guide device consisting of a fitted guide roller on the glass side.

Some window glass lifting devices use door sashes to guide the window gas on both sides, but if the sashes are not parallel, at least one edge will come off the door sash when the glass is lowered! Therefore, at that tt, there is a risk that the glass may rotate and become damaged. Therefore, by attaching a guide roller to the glass holder at the lower end of the glass, fitting this guide roller to the idle rail arranged inside the door panel, and moving it up and down along the guide rail, the door panel can be moved up and down.
Some are designed to prevent the glass from rotating.

However, in such an elevating guide device, if the guide rail and the lower guide roller are fitted with precise dimensional accuracy with no looseness between them, a large sliding resistance is generated, which impairs the ease of nozzle operation. Since the edges will be wrinkled, they are fitted so that there is a slight gap in advance. As a result, looseness occurs between the guide roller, guide rail, and zero.
There were problems such as the glass tilting slightly and making strange noises.

This invention focuses on the above-mentioned problems, and aims to prevent mold from forming on the shield glass by eliminating looseness between the guide rail and the guide roller in an elevating guide device consisting of the guide rail and the guide roller. For this purpose, attach a pair of guide rollers to the glass holder that fit inside the guide rail, and insert the guide rollers into the guide rail from opposite directions, respectively, on the outside of the guide rail corresponding to this guide roller. It is characterized by providing a biasing means for press-contacting.

This development will be explained below based on the drawings.

In this embodiment, an o')-type elevating device, which has a basic configuration of a rack and a binion that are engaged with each other, which was developed by the present applicant for the purpose of narrowing the door width, will be described.

FIG. 1 shows the overall structure of the lifting device, where l is a rear door of an automobile, 2 is a door sash, and 3 is a windshield. The windshield 3 is guided along a center sash 2a and moves up and down. ing. A glass elevating device is built in the door channel la of the door 1. 4 is a rack case arranged between the door inch panel and the window glass 3 and fixed to the door inner funnel by brackets 5, 6, and 18; A flexible resin rack 9 is slidably inserted into the rack case 4 using a guide rail fixed to the nanocinel. As shown in FIG. 2, a knob shaft ν having a binion 10 meshing with the rack 9 at one end and a regulator knob 11 at the other end is rotatably attached to the bracket 6, as shown in FIG. In addition, guide rollers 14 and 14' attached to the glass holder (2) are slidably fitted to the guide rail 7, and
As shown in FIG. 3, the glass holder opening is held and connected to a part of the rack 9, and the lower end of the window glass 3 is fixed and held to the glass holder 13 by pins 115, 15.

Therefore 1. When the handle 11 is rotated, the binion 10
is rotated, the rack 9 meshed with this slides inside the rack case 4, the glass holder 13 connected to the other end of the rack 9 is moved upward or downward, and the glass holder opening and the window glass 3 are guided. It is moved up and down along the rail 7. The handle shaft U is provided with a reversal prevention mechanism 16 of a known structure. FIG. 4 shows details of the elevating guide device.
Nine pairs of guide rollers 14, 14 are slidably fitted together.
' is attached. A presser roller 21 facing the guy roller 14 with the guide rail 7 sandwiched between the guide rollers 7 and 14a formed on the glass holder ■ corresponds to the guide roller 14 at the upper part of the glass holder ■.
The presser roller 21 is slidably attached by a holder n that holds it, and this presser roller 21 is always directed toward the guide rail 7 by the end 25a of the screw spring 6 that is locked to the pin 24, and corresponds to the bias 14'. The presser roller 21 contacts the guide rail 7 from the opposite direction to the guide roller 14.
' is likewise slidably mounted within the elongate 141';
It is urged toward the guide rail 7 by a screw or a spring.

In this way, the press rollers 21 and 21', which serve as biasing means for pressing the guide rollers 14 and 'x4' against one side of the guide rail 70, are respectively provided on the opposite side of the guide rail 7. When the windshield 3 is placed behind the door 1, the rear window glass 2afC of the door 1 is placed to lean against it.The moment of clockwise rotation that causes the window glass 3 to rotate backwards causes the guide roller 14 to move against the right side wall 7a of the guide rail 7 and against the guide roller 14. , -214' are pressed against the right side wall 7b, and thereby the guide rollers 14, 14
' There is no looseness between the guide rail 7 and the windshield 3, and the windshield 3 is tightly fitted to the rear sash 2a, thereby preventing mold and mildew.

FIG. 6 shows another embodiment of this M9IO, in which a curved plate spring n is used as the biasing means, and this plate spring n is attached to the glass holder by a locking piece n, and the guide row 214 is attached to the glass holder.
The guide rail 7 is brought into contact with the side wall of the guide rail 7 so as to face the guide rail 7.

Further, although not shown, a similar leaf spring is provided on the opposite side of the guide rail 7 in correspondence with the guide roller 14'.

Even in this case, the same effects as in the embodiment described above can be obtained.

In Fig. 7, a rubber device is fixed to a glass holder facing a guide row 914, and a biasing means is brought into contact with the side wall of the guide rail 7 by making a rubber device (7) 3G attached to one side of the rubber 9 come into contact with the side wall of the guide rail 7. An example of the configuration is shown below.

As explained above, this I&- is a non-parallel satchet type window f! by attaching a pair of guide rollers that fit into a guide rail to a glass holder. (A biasing means is provided on the outside of each guide rail corresponding to each guide roller to press the guide rollers against the guide rail from opposite directions.) Therefore, the pair of guide rollers are always moved up and down while being in pressure contact with the guide rail.
There is no backlash between the guide 4-ra and the guide rail (1k)
, Also, the window glass is suitable for door sashes.11KmK
It has the effect of preventing mold and mildew from forming, and also eliminates abnormal noises.

In the above embodiment, a door window glass lifting device has been described, but it goes without saying that the present invention can also be applied to a door window glass lifting device. Meeting nine,
In the embodiment, a case has been explained in which the present invention is applied to a rack type lifting device, but it can also be applied to a lifting device such as a Golde type or a tape type.
