Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a structure in a delta sash of an automobile.

[Prior Art] FIG. 11 shows a conventional passenger car. Generally, a delta sash 2 is provided at a front door 1 of the passenger car.
Is provided.

The conventional delta sash 2 is constructed as shown in FIG. That is, the core material made of the sheet metal 3 is covered with the rubber covering material 5, and the tongue pieces 7, 7 which are in sliding contact with the door glass 6 at the leading edge portion of the covering material 5 are formed. The cross-sectional shape of the delta sash 2 is a constant shape regardless of its cross-sectional position, and the interval between the pair of tongue pieces 7 sandwiching the door glass 6 does not always change.

On the other hand, the ascending / descending locus L of the door glass 6 which moves vertically while being slidably held between the tongues 7 of the delta sash 2 is
It is constant as shown in Fig. 13.

[Problems to be Solved by the Invention] As described above, the conventional delta sash 2 is effective only when the ascending / descending locus L of the door glass 6 is constant. However, as is often the case with modern luxury cars, for example, in the case where the door glass 6 has a three-dimensional curved surface, the locus L of the door glass 6 swings left and right as the door glass 6 moves up and down, and the locus L has a width.

In such a case, a strong rubber-elastic reaction force is applied to the tongue piece 7 on the side of the swing, and a large frictional force is generated in the sliding door glass 6, impairing its up-and-down performance.

Further, due to the same reason, the swinging door glass 6 exerts an unreasonable force on the sealing tongues 7,7, which deteriorates the durability of the tongues 7,7.

The present invention has been made in view of the above problems, and its purpose is to have a strong rubber elastic reaction force on the tongue for sealing, even if the locus of the door glass is swayed to the left or right as the door glass moves up and down. (EN) Provided is a delta sash structure for an automobile, which can improve the ascending / descending property of a door glass which can be ascended / descended without adding a tongue, and the durability of its tongue piece.

[Means and Actions for Solving the Problems] In order to solve the above problems, the present invention is directed to a vehicle used for a door glass in which the locus position of the door glass fluctuates as the door glass moves and the locus has a width. In the delta sash structure, a pair of left and right tongues are formed that sandwich the edge of the door glass with the edges of the elastic covering material that covers the core material and seal the door glass in a slidable contact manner. The protruding length of the tongue is adjusted so that the reaction force of the tongue does not increase in accordance with the movement of the tongue.

However, since the door glass has a three-dimensional curved surface, when the door glass moves up and down, the locus of movement moves left and right as compared with the position when the door glass is closed, and even if the locus has a width, the shake side The reaction force of the tongue corresponding to is small,
Since it is flexible, it does not give a large frictional force to the door glass sliding on the tongue. Further, it is possible to improve the operability of raising and lowering the door glass and enhance the durability of the tongue piece.

[Embodiment] FIGS. 1 to 8 show an embodiment of the present invention. FIG. 1 is an external view of the delta sash portion of the passenger car. This covers a core material 11 made of sheet metal with a rubber covering material 12, and constitutes a pair of left and right sealing tongue pieces 14a, 14b which are in sliding contact with the peripheral edge portion of the door glass 13 at the tip edge portion of the covering material 12. ing. A mounting portion 15 attached to the door frame is formed below the core material 11.

The door glass 13 is formed on its three-dimensional curved surface as shown in FIGS. For this reason,
Each position when the door glass 13 is raised and lowered changes depending on each moving position as shown in FIG. 7, and swings to the left and right.
That is, as shown in FIG. 8, the moving locus L is different from the position 1 when the door glass 13 is completely closed,
In particular, if the door glass 13 is opened, the swinging range becomes wider as it is opened.

Therefore, as shown in FIG. 2, FIG. 3 and FIG. 8, the sealing tongue piece 14a on the shake side of the door glass 13 depends on the shake of the door glass 13, that is, as it moves from the upper part to the lower part. Increase the a dimension and the b dimension. When the door glass 13 is opened, the lower side of which the swing width expands, the dimensions a and b increase, the free length of the tongues 14a and 14b increases, and the flexibility increases.

Even when the door glass 13 has a three-dimensional curved surface, the door glass 13 swings left and right as compared with the position 1 when the door glass 13 is closed due to its ascending / descending, and there is a difference in the moving position. Since the tongue piece 14a on the swinging side is long and flexible, a strong reaction force of rubber elasticity is not applied thereto. Therefore, a large frictional force is prevented from being generated on the door glass 6 with which the tongues 14a and 14b are in sliding contact, and the operability of raising and lowering the door glass 6 is not impaired. Further, since no unreasonable force is applied to the swing-side tongue piece 14a as the door glass 6 moves up and down, the durability of the tongue pieces 7, 7 is not impaired.

9 and 10 show another delta sash portion. In this example, the core material 11 is composed of a plurality of metal plates 11a and 11b, and each metal plate 11a and 11b is formed in a cross-sectional shape as shown in FIG. 9, and a and b parts are welded and integrally fixed. . And, in particular, only the front and rear parts of the core material 11 are covered with rubber 12
Cover with. Also, in the central part where there is no covering 12,
By covering the portion where 11a is visible with a resin cover 16, deterioration of appearance can be prevented.

Therefore, by constructing the cross-sectional shape of the core material 11 as shown in FIG. 9, it is possible to reduce the amount of the metal plates 11a and 11b. Further, since the rubber covering material 12 is provided only on the front and rear portions of the core material 11, the amount of the covering material 12 can be reduced. Therefore, the cost can be reduced.

Further, the one having such a structure is suitable for the one in which the rigidity of the delta sash portion is not so much required as in the above-mentioned embodiment.

[Effects of the Invention] As described above, according to the present invention, in the case where the locus of the door glass swings to the left or right as the door glass moves up and down,
It is possible to improve the up-and-down property of the door glass that moves up and down and the durability of the tongue piece without applying a strong rubber elastic reaction force to the sealing tongue piece.
