Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a door glass seal structure for a satsileless door of an automobile, and particularly to a door glass sealing technique for a satsileless door having a triangular patch.

(Prior Art) Conventionally, as shown in FIG. 1, a door glass 3 of a sashless door having a triangular patch 1 and a glass run 2 has a shape of an upper end on the front side of the vehicle that is formed by an upper end line 3a and a front end line 3b. The lines were extended straight as they were, and their intersections were gently connected by a circular arc line 3c. The upper end of the vehicle front side of the door glass 3 having the shape described above has a sealing structure in which the end 2a of the glass run 2 and the weather strip 5 provided on the vehicle body 4 are overlapped and sealed.

However, in such a conventional door glass seal structure, when the door glass 3 is raised to the highest closed position, the thickness of the end 2a of the glass run 2 is added to push up the weather strip 5, and the reaction force (in the direction of arrow B in Figure 1) is trying to act as a sealing force on the door glass 3, but the force that slightly pushes up the thickness of the end 2a of the glass run 2 leads to an increase in reaction force. However, as shown in FIG. A gap t is formed in the area surrounded by the three parts 5 and 5, and there is a problem in that rainwater or the like flows into the vehicle interior through the gap t.

Therefore, if the sealing performance is low due to the small reaction force as mentioned above, we thought that it would be better to increase the sealing reaction force from the weather strip 5. Even with this door glass seal structure, the hollow part of the weather strip 5 was filled with sponge 6.

However, in the case of a suctionless door, increasing the seal reaction force too much will affect the door closing force, so even if the sponge 6 is filled, the amount of increase in the seal reaction force is limited, and the seal reaction force The increased amount was simply dispersed throughout, and even if a weather strip 5 having a structure filled with sponge 6 was used, a gap t would be created as described above.

(Purpose of the invention) The present invention was made to solve the above-mentioned problems, and its purpose is to create a door glass seal that can reliably seal the door glass of a door without a triangular patch. It consists in providing structure.

(Structure of the invention) That is, in order to achieve this object, the present invention includes a door glass provided on a sutureless door so as to be movable up and down, a glass run provided on a triangular patch of the sutureless door for sealing the front end of the door glass, A door glass seal structure for a door glass door having a weather strip provided on the vehicle body for sealing the upper end of the door glass and the upper end of the triangular patch, wherein the door is sealed with the glass run and the weather strip overlapping each other. The upper end of the glass on the vehicle front side extends above the upper end extension line of the door glass.

(Effect of the invention) Therefore, in the door glass seal structure of the present invention, the upper end of the door glass on the vehicle front side extends above the extension line of the upper end of the door glass. In order to achieve this, the upward extension amount, the weather strip, and the glass run are pushed up, and the weather strip and the glass run are partially deformed greatly, and this deformation produces a locally concentrated high sealing reaction force, ensuring that no gaps are created. This has the effect of sealing the upper end of the door glass on the vehicle front side.

Further, since the seal reaction force mentioned above is concentrated only in one part, it does not affect the door closing force.

In addition, although it is extremely concise in structure,
As mentioned above, it shows a high sealing effect.

(Example) In describing an example, a door glass seal structure of a sillless door of a two-door type automobile will be taken as an example, and the same parts as in the conventional structure will be given the same reference numerals.

3 to 7, reference numeral 3 denotes a door glass, which is guided by guides 8, 8 of the door 7 and is movable up and down by a window regulator (not shown).

1 is a triangular patch, and the door 7 is a triangular patch.
This triangular patch 1 is integrally fixed to the upper end of the front side of the vehicle with the door 7.
In some cases, the triangular patch 1 is provided merely for decoration, but in this embodiment, the triangular patch 1 is provided for attaching the door mirror 9.

Reference numeral 2 denotes a glass run, which is bonded to the rear end of the triangular patch 1 for sealing by sandwiching the front end of the door glass 3, and is made of a rubber material.

A weather strip 5 is fixed to the vehicle body 4 in order to seal the upper end of the door glass 3 and the upper end of the triangular patch 1. As shown in FIG. The weather strip retainer 10 is provided with a hollow structure having an outer seal portion 5a and an inner seal portion 5b, and is a continuous extrusion molded product made of rubber. Next, the characteristic configuration of the embodiment of the present invention will be explained.

First, as shown in FIG. 5, the shape of the upper end of the door glass 3 on the vehicle front side is such that it has an upwardly extending portion 3d extending above the upper end extension line 3a of the door glass 3. The outer shape of the upwardly extending portion 3d is a gently curved shape.

Further, as shown in FIGS. 5 and 6, the portion of the weather strip 5 overlapping with the glass run 2 is partially filled with sponge 6a to increase the sealing reaction force locally.

In the figure, 1a indicates the inner frame plate of the triangular patch 1, 1b the resin-covered plate of the triangular patch 1, 1c the mounting hole for the door mirror 9, and 1d the interior side finisher of the triangular patch 1. As shown in FIG. 7, the mounting hole 1c of the door mirror 9 has a bent portion 1e formed by bending the resin-coated plate 1b on the inner circumferential surface of the mounting hole 1c. This prevents the inner frame plate 1a from rusting due to infiltration.

Therefore, when the door glass 3 is raised to the closed position, which is the highest position, as shown in FIGS. The amount of upward extension by the upwardly extending portion 3d pushes up the weather strip 5 and the end portion 2a of the glass run 2, allowing the weather strip 5 and the glass run 2 to be greatly deformed. When the sealing member deforms in this way, a locally concentrated high sealing reaction force (in the direction of arrow C in FIG. 5) is obtained due to the restoring force proportional to the amount of deformation, and the door glass 3, glass run 2, and weather strip 5 Even in the area surrounded by the three parts, the deformation of the sealing member allows it to come into close contact with the end face of the door glass 3 and reliably seal the upper end of the door glass 3 on the front side of the vehicle without creating a gap. can.

Furthermore, in the embodiment, since the weather strip 5 is partially filled with the sponge 6a, the above-mentioned sealing effect is achieved by increasing the sealing reaction force, resulting in extremely high sealing performance.

Furthermore, since the sealing reaction force mentioned above is concentrated and increased only in one part, and the filling of the sponge 6a is also limited to one part, it is difficult to increase the sealing reaction force as a whole. The closing force does not become stronger.

Moreover, although the structure is such that the upwardly extending portion 3d is formed in the door glass 3 and the sponge 6a is only partially filled, it exhibits an extremely high sealing effect as described above.

Although the embodiment of the present invention has been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment. For example, the amount of upward extension of the door glass may be set as appropriate according to necessity. It's okay.

Furthermore, filling the weatherstrip with sponge is not necessarily required; it may be replaced by changing the material of the weatherstrip itself, making the weatherstrip partially thicker, or even using a conventional hollow weatherstrip. The sealing effect can be improved.
