DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a triangular window device suitable for use in doors of vehicles, particularly cab-over trucks.

(Prior Art) A typical configuration of a triangular window device installed in a door of a conventional cab-over type truck is referred to FIG. 1 showing an embodiment of the present invention for convenience, and also shown in FIG. A description will be given with reference to a sectional view of the sash portion (corresponding sectional view in the sectional view taken along the line II-II in FIG. 1). Reference numeral 10 in the drawing generally indicates a door provided in the cab of the truck, and an arrow In in FIG. 1 indicates the inside of the vehicle, an arrow On indicates the outside of the vehicle, and an arrow F indicates the front of the vehicle body. A triangular window device, generally indicated by reference numeral 12, is provided at an upper front end portion of the door 10, and a main window 14 which is opened and closed by vertically displacing the window glass is provided behind the triangular window device.

(Note that, since the present invention is not directly related to the main window 14, the detailed structure is not shown in FIG. 1.
In the case of a cab-over type truck, the triangular window device 12 usually has a trapezoidal shape as shown in the figure, but since this type of window is conventionally called a triangular window, it is necessary to follow the custom in the technical field. To do. ) The triangular window device 12 includes a thin steel plate sash 16 whose detailed cross-sectional shape is shown in FIG. 3, and a longitudinal rotation axis XX.
Upper and lower support fittings 18 and 20 so that they can be rotated around the
The window glass 22 supported by the sash 16 and the weather strip 24 whose outer peripheral edge is supported by the sash 16 are provided. The weather strip 24 includes a pair of locking lips 28a and 28b elastically locked to a pair of locking edges 26a and 26b formed on the edges of the sash 16 facing the window glass 22, respectively. The locking lips 28a and 28b are shaped to have a substantially symmetrical cross-sectional shape with respect to the center line of the window glass and the sash. The weather strip 24 is used for the window glass 2
2, a main seal lip 30a having a large cross-sectional area that elastically abuts the peripheral edge portion of 2 to form a fluid contact hand, and the window glass 22.
And a sub-seal lip 30b having a small cross-sectional area that elastically abuts the outer peripheral end surface of the to form a fluid contacting hand.

When the window glass 22 is in the normally closed position shown in FIG. 1, the main seal lip 30a is applied to the window glass by an external force around the rotation axis XX as indicated by an arrow A in the figure. In addition, it also has the function of holding the window glass in the closed position against the rotational moment thereof, together with the sealing action. The locking lips 28a and 28b are
In consideration of workability when attaching the weather strip 24 to the sash 16, the weather strip 24 is provided in a shape that is easily bent to some extent. Therefore, when a relatively small external force is applied to the window glass 22 and the rotational moment thereof exceeds the set value, the locking lip 28b on the side opposite to the main seal lip 30a is easy as shown by the alternate long and short dash line in FIG. On the locking edge 26b of the sash
And the window glass 22 excessively rotates beyond the normally closed position. (Note that in the case of the left door 10 shown in FIG. 1, the main seal lip 30a of the weather strip 24 is in contact with the outer peripheral surface of the window glass 22, that is, the inner surface of the vehicle, in the front portion of the rotation axis XX. (Problems to be solved by the device) The present invention is designed to set an excessively large limit rotational moment for rotating the window glass in the closing direction beyond the normally closed position, thereby excessively rotating the window glass. It is an object of the present invention to provide a triangular window device which is configured to prevent movement and not impair the workability of attaching the weather strip to the sash.

(Means for Solving the Problems) The present invention was created to achieve the above object, and is a window glass pivotally supported about a rotation axis extending in the longitudinal direction, The sash that surrounds the outer peripheral edge of the window glass, and a pair of locking lips that engage with the locking edges of the sash are provided on the outer peripheral edge, and the inner peripheral edge of the sash abuts against the peripheral edge portion of the window glass and is in fluid contact. Forming a hand,
What comprises a weather strip having at least one main seal lip for restraining the closed position by restraining the excessive rotation of the window glass, of the pair of locking lips of the weather strip, The gist of a triangular window device of a vehicle is characterized in that a cross-sectional area of a locking lip on the side opposite to the main seal lip is formed to be sufficiently larger than a cross-sectional area of a locking lip on the main seal lip side.

(Operation) According to the present invention, of the pair of locking lips for attaching the weather strip to the locking edge of the sash, the locking lip on the side of the main seal lip is relatively flexible with a small cross-sectional area as in the conventional case. Although the shape is easy, the locking lip on the side opposite to the main seal lip is formed to have a sufficiently large cross-sectional area. By forming the cross-sectional area of the locking lip on the side opposite to the main seal lip large enough, the resistance moment of the weather strip against the external force that attempts to rotate the window glass from the closed position further excessively- And excessive rotation beyond the closed position of the glazing is effectively suppressed. Further, since the locking lip on the same side as the main seal lip is formed to be easily bent as in the conventional case, the weather strip can be easily assembled to the sash by using this lip.

(Embodiment) Hereinafter, an embodiment of the present invention will be specifically described with reference to FIGS. 1 and 2 (note that the matters already described with reference to FIG. 1 and FIG. According to the present invention, the locking lip 28a on the side of the main seal lip 30a of the weather strip 24 is the same as that of the conventional weather strip, as clearly shown in FIG. Is formed to have a small cross-sectional area, but the locking lip 28 on the side opposite to the main seal lip 30a.
As shown in the drawing, b is formed to have a sufficiently large cross-sectional area.

Therefore, from the fully closed position of the window glass 22 shown by the solid line in FIG.
When an external force A that tries to rotate around -X is applied, the limiting resistance moment generated by the locking lip 28b is significantly increased as compared with the related art, so that the locking lip 28b cooperates with a normal external force. Sash locking edge 26
It does not come off from b, and there is no problem that the window glass 22 excessively rotates beyond the normally closed position. Further, since the locking lip 28a on the side of the main seal lip 30a is formed so as to be easily bent as usual, the weather strip 2
4 is attached to the sash 16, first, as shown by the one-dot chain line in FIG.
8b is engaged with the locking edge 26b of the sash 16, and then the flexible clip 28a is pushed toward the sash side to engage with the locking edge 26a, thereby substantially assuring assembling workability. be able to. Further, the weather strip 24 is provided with only one locking lip 28b.
Since the cross-sectional area of is simply larger than the conventional one, the structure is extremely simple and the price is low.

When the triangular window is opened for ventilation in the passenger compartment, a force in the opposite direction to the external force A is applied from the passenger compartment to rotate the window glass 22 in the opposite direction around the rotation axis XX. Just do it.

(Effects of the Invention) As described above, the triangular window device for a vehicle according to the present invention has a window glass pivotally supported about a rotation axis extending in the longitudinal direction, and an outer peripheral edge of the window glass. And a pair of locking lips that engage with the locking edges of the sash on the sash that surrounds the sash. , A weather strip having at least one main seal lip for restraining the closed position by restraining the excessive rotation of the window glass, of the pair of locking lips of the weather strip. , The cross-sectional area of the locking lip on the side opposite to the main seal lip is formed to be sufficiently larger than the cross-sectional area of the locking lip on the main seal lip side. Effectively prevent being rotated It is extremely advantageous because it is possible to provide an apparatus of this type at a low cost that does not impair the workability of assembling the weather strip to the sash.
