DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide structure for an ascending and descending door glass having a sash for guiding the ascending and descending of the door glass in a main body of a door of an automobile.

[0002]

2. Description of the Related Art As shown in FIG. 2, a door body 2 guides a front edge and a rear edge of a door glass 2 to a front and rear position between an inner panel and an outer panel when the door glass 2 moves up and down. A sash 3 is provided.

Conventionally, metal sashes have been used,
A separate glass run was attached to this, but recently a synthetic resin made of nylon, polyacetal, or the like has been used to reduce the weight and cost of the vehicle.

In this sash made of synthetic resin, the glass run is omitted, the sash having a U-shaped cross section as shown in FIG. 3 is used in order to secure the sliding property of the ascending and descending door glass and to prevent rattling of the door glass. The projections 4 projecting from the inner surface 32 are formed on the inner surface 32 of the three opposing side walls 31 at opposing positions or at alternate positions in the longitudinal direction of the sash (see Japanese Utility Model Application Laid-Open No. 59-102867).
issue). However, since synthetic resin expands and contracts due to heat as compared with metal, it is necessary to provide a sufficient space between the glass surface and the projections 4, and it is not possible to sufficiently prevent rattling of the door glass. Was.

Therefore, in order to prevent rattling of the glass regardless of the temperature change, a plurality of lips 5 each having a substantially C-shaped cross section whose one end is connected to the inner surface 32 are provided on the opposing inner surfaces 32 as shown in FIG. A sash 3 formed at a predetermined interval in the longitudinal direction of the sash has been proposed (Japanese Patent Laid-Open Publication No. Hei 9 (1999)).
-100676). According to this, since the lip 5 absorbs thermal expansion and contraction due to its flexibility, the lip 5 can always be brought into contact with the surface of the door glass 2, and rattling of the door glass does not occur.

[0006]

By the way, the door glass is generally formed to have a curvature corresponding to the side shape of the vehicle body, and the sash is also formed to have a curvature corresponding to the curvature of the door glass.
When the door glass is moved up and down, the curvature of the sash does not always coincide with the locus of the side edge of the door glass, and the side edge of the door glass swings relatively to the sash. Therefore, the width of the sash is set to a width that allows the lateral swing. However, on the other hand, since a member such as a lock device is provided near the sash in the door main body, it is desired that the width of the sash be as small as possible.

Therefore, when the width of the sash 3 on which the lip 5 is formed is set to be as narrow as possible to allow the lateral deflection of the door glass 2, one surface of the door glass 2 is opposed to the sash 3 at the maximum lateral deflection. When approaching the inner surface 32 of
The door glass opening / closing force increases rapidly due to the reaction force at the base of the lip 5 that is difficult to bend. Then, rubbing between the door glass 2 and the lip 5 causes an abnormal noise. Therefore, in order to keep the opening / closing force of the door glass low, the width of the sash 3 is limited by a considerable gap between the lip 5 pushed in at the maximum amplitude of the door glass 2 and the opposing sash inner surface 32. Must be set to a width that will

Accordingly, the present invention provides a lift door glass guide structure in which sashes having lips sandwiching both sides of a side edge of a door glass are provided on opposing inner surfaces, without increasing the opening / closing force of the door glass. It is an object to set the width as small as possible.

[0009]

SUMMARY OF THE INVENTION The present invention provides a sash provided in a body of a door, wherein opposite sides of the sash are provided with lips for sandwiching a side edge of a door glass from both sides thereof. Extend in a direction rising obliquely to the inner surface, and have a cross-sectional shape in which a distal end portion is inverted and bent in a letter shape from the base end portion to extend. A lip base is connected to the opening edge on the lip side of the inner surface of the sash, and a concave portion having a depth and an area sized to receive the base end portion of the lip which is turned down toward the inner surface is formed.

The lip that sandwiches the door glass from both sides has a bent portion, and the base is formed on the opening edge of the recess so that the base can easily fall down to the recess side, so that the base end can be inserted into the recess. It easily bends with a low load until it reaches the state where the tip of the collapsed portion substantially overlaps the inner surface of the sash. Therefore, the interval between the opposing inner surfaces of the sash can be set to an interval close to the lateral swing width of the door glass, and the width of the sash can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 2, a sash 3 for guiding a front edge and a rear edge of an ascending and descending door glass 2 is installed vertically in a door body 1 of an automobile, respectively. It is.

The front and rear sashes 3 are substantially symmetrical in shape and are injection molded articles of synthetic resin. Taking the sash 3 on the front side as an example, as shown in FIG. A bracket 30 is provided on one outer surface, and the bracket 30 is fixed to the inner panel of the door body 1 by the bracket 30. Although the sash 3 is drawn in a straight line in FIG. 1A, it is actually formed in a gently curved shape corresponding to the curvature of the door glass.

On the inner surface 32 of both side walls 31 of the sash 3,
A plurality of lips 6 are formed at predetermined intervals in the longitudinal direction of the sash, and the lips 6 on both sides are at alternate positions. Each lip 6 is thinner than the side wall 31 and extends above the sash 3 in a rising direction at an acute angle with respect to the inner surface 32, and reversely bends in a V-shape and rises obliquely with respect to the inner surface 32 below the sash 3. It has a cross-sectional shape extending to the side. From the base 60 of the lip 6 to the bent portion 6
The length of the base portion 61 reaching the length 3 is about the thickness of the side wall 31 and is short, and the length of the tip portion 62 from the bent portion 63 to the terminal is longer than the base portion 61 and is about twice as long. . The width of the lip 6 is slightly smaller than the width of the side wall 31.

The inner surface 32 of the side wall 31 has the base end 61 formed thereon.
A concave portion 33 is formed at a position opposed to. The opening edge 331 of the concave portion 33 on the lip 6 side enters under the root 60 of the lip 6, and has a structure in which the root 60 of the lip 6 is connected to the opening end of the opening edge 331. The depth of the concave portion 33 is set to be slightly deeper than the thickness of the base end portion 61 of the lip 6, and the width is almost the same as the base end portion 61.
1 is received in the recess 33. The hole 34 located at the position corresponding to the lip of the sash 3 main body is a hole from which a lip molding pin has been removed when the sash 3 is injection-molded with a mold.

In the sash 3, the door glass 2 is moved up and down with the front edge of the sash 3 sandwiched by both sides of the lip 6, and the lateral deflection of the door glass 2 is absorbed by the deformation of the lip 6. In this case, when the front edge of the door glass 2 is displaced in the width direction of the sash 3 due to lateral deflection, the lip 6 on the compression side is bent at the distal end portion 62, the bent portion 63 is bent in the folding direction, and the base end portion 61 is bent. Are inclined in the direction of the concave portion 33 from the root 60 thereof, so that the bending load of the entire lip 6 hardly increases.
The lip 6 can be deformed until its base end 61 falls completely into the concave portion 33 and the front end 62 is folded and almost overlaps the inner surface 32 of the sash 3. The deflection load of the lip 6 hardly increases.

Therefore, the width of the sash 3 can be set substantially in accordance with the sash width direction interval between the lips 6 in the maximum deformation limit state of the both lips 6 and the maximum lateral deflection width of the door glass 6, so that the conventional sash 3 described above is used. The width can be smaller than that of the lip sash.

Although the lips 6 on both sides are formed at alternate positions in the above-mentioned example, they may be formed at opposing positions. Each lip 6 has a base end 61 extending obliquely downward with respect to the inner surface 32 toward the lower side of the sash 3 and a distal end 62.
May extend upward of the sash 3.
