Abstract

PURPOSE:To obtain a window panel guide device to be formed conveniently by joining the internal edge part of the base part of a glass run outer side with the back of a seal lip root by means of a padding rib. CONSTITUTION:A padding rib 20, formed bead-like in the range of the length of a projected expansion part 18, is made in one body with a glass run 10 along with the expansion part 18. The upper end part 3a of a door glass makes contact with a slant face 18a of the expansion part 18 at the last stage of closing a door glass 3. When closing action is continued in this condition, although the expansion part 18 shows inclination to curve in X direction, the padding rib 20 strongly resists the curving deformation. The door glass upper end part 3a, being unable to stand the resistance of the rib 20, slides along the slant surface 18a and is guided to the regular seal position where it makes elastical contact with seal lips 14, 16.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wind panel guide device.

Generally, when opening and closing a wind panel, such as a front door glass, along the door sash, the top edge of the glass should be opened and closed along one edge of the front door sash to prevent the top edge of the glass from protruding from the sash at the end of the closing period and not closing at the proper seal position. A glass guide device is provided in the glass section, and this guide device automatically guides the glass to the proper sealing position within the scythe at the upper end of the glass, ensuring sealing performance when the glass is fully closed. Conventionally, the guide device shown in FIG. 2 or 3 is well known. In the case of FIG. Door weather strip 2 that seals between the vehicle body and the door by coming into elastic contact with the front and top pillar P
A glass run is fitted to the inner peripheral edge of the door glass 3, which circumscribes the peripheral edge of the door glass 3 as a window panel and seals between the door sash l and the door glass 3.

, this glass and the rung include a U-shaped base lIO that is held by a satsume l, and a pair of seal lips 112 that extend from the inside surface of the cylinder of this base 110. Consisting of 'I'l' and 1
, A bulge 6 is provided at the outer side end of the base I10 and extends from the sash 1 to the heavy side E, and the bulge I6 has a slope that smoothly continues toward the seal lip 't, 2. A plane ψ6a is formed.

In addition, 6 roughly oval-shaped reinforcing plates are provided at the portion 81S that protrudes from the bulging portion Il of this glass rung. A wind tunnel (glass guide device) is constructed, so that when the glass 3 is closed, the glass 7'I is closed at its final stage.
When the MA part 3a contacts the stop slope 116a and the glass 3 is closed in this state, the seal 1 notch 17 is inserted along the slope 116a with its first end 3aJ'' as shown by the imaginary line along the slope 116a.
2. In the case of Fig. 3, the bulging part q6 is not protruded from the glass rank, and a lubrication force is applied to the seal lip I12) Slope J' continuous to
A guide plate with a force on it is held between a sash l and a glass run t, and the guide plate constitutes a guide device.

However, in the first guide device of this kind, that is, in the one shown in Figure 2, the reinforcing plate B must be buried, which increases manufacturing costs, and it is necessary to bury the reinforcing plate B in the thin glass run q without exposing it. It is difficult to apply flocking to the seal lip 2゜IItl where the reinforcing plate 2 is present, which requires high precision and is difficult to manufacture, and it increases the sliding resistance when opening and closing the glass, making it difficult to operate. There is also the problem of compromising sexuality.

In the case shown in Figure 3, there is a risk that the guide plate and the cover may rub against each other, causing the paint on the cover to peel off and cause rust. There is a risk that the plate t will collide with the plate t and generate a hitting sound, resulting in a quality loss.

The present invention has been made in view of such conventional problems, and it is an object of the present invention to provide a wind panel guide device that is inexpensive and easy to manufacture without impairing operability, rust prevention, etc. In order to achieve this purpose, a protruding portion is provided on the glass run, and a built-up rib is formed on the inner side of the end of the outer base of the glass run, where the protrusion is formed, and on the back surface of the base of the seal lip that connects to the protrusion. 1. The upper end of the wind panel touches the bulge while the wind panel is closed. When the flannel is closed, the overlay ribs tighten and restrict the deflection of the bulge. The seal is guided to the proper seal position where it makes elastic contact with the seal lip.

According to the embodiment shown in the drawings, 7t, which is the same as the conventional one (5 minutes are given the same reference numerals), in Figures V and J, / is the door sash, and 2 [1 and the same number]. The door weatherst 9 tab 2 is engaged with the outer periphery of the opening, which makes elastic contact with the opening periphery of the heavy body, and the glass run 10 car is fitted on the inner periphery. A U-shaped base/Y is held by the U-shaped base 12, and a winton (
It is equipped with a pair of seal lips/gears and IA that come into elastic contact with the door glass 3 as a panel, and the width of this base l is 11+ outside.
One end l core aK extends j1 from the sash l to the outside E of the vehicle, and is provided with a protruding portion having a sloped surface/ramp that smoothly continues toward the seal lip lμ.

1, the back surface of the base /la of the seal lip /l that continues to the bulge /g, the outer side end of the base 12 /, and the inside of la are connected by a build-up rib 1.0. As shown in FIG. 5, this build-up rib 20 is formed in a bead shape in the length range where the bulge/crop protrusion is provided.
It is manufactured by integral molding with the glass run 10 together with the bulging part /I.

With this configuration, when the door glass 3 is closed, at the end of the closing period, the door glass L end 3a reaches the end of the bulge 1g.
When it comes into contact with the
When the cut tries to bend and bend in the direction, the overlay Lipco O strongly pushes against the bending deformation and bends.Unable to resist this bend, the door glass and the end 3a move along the inclined surface Ig&. It slides and is guided to the normal seal position where it comes into elastic contact with the seal lips /μ, /l as shown by the imaginary lines.

6 to 9 show other embodiments, and to explain only the differences from the previous embodiments, the overlay is 1 nop, λO'
As shown in FIG. 7, the grooves are formed at three locations at appropriate intervals in the longitudinal direction of the glass run, all of which are the back surface of the base/qa of the seal lip A connected to the bulge and the outer side end/2a of the base 12. is connected to the inside of the

With this configuration, the built-up rib 20' is in a free state as shown in Fig. 1, and in this state, the upper end portion 3a of the door glass comes into contact with the bulge l♂, and the bulge l is exposed to the outside of the vehicle. When an attempt is made to bend the glass, the upper end 3a of the glass is strongly resisted by being stretched and guided to the proper sealing position as shown by the imaginary line in Fig. 6. At the normal sealing position, it is easily bent into a dogleg shape as shown in Fig. 9. This reduces the sliding resistance of the glass when guiding it to the normal seal position and the increase in seal reaction force at the normal seal position.

Therefore, according to this invention, the bulging portion and the overlay rib can be formed at the same time as the glass run is formed, and there is no need to embed a reinforcing grate as in the conventional method, so it can be manufactured at low cost. be.

゛ In addition, since the seal lip can be flocked in its unfolded state, it does not impair operability.Furthermore, the quality can be improved without causing rust or hammering noise due to rubbing between the seal lip and the satush. This effect can also be obtained.
