Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass run for an automobile which is attached to a sash portion of a door of an automobile and seals an edge of a windshield.

[0002]

2. Description of the Related Art Conventionally, as this type of glass run for automobiles, a fin-shaped locking projection is formed on the outer end side of the side wall, and the locking projection is provided at the opening edge of the sash. It is known that the glass run is held so as not to slip out of the sash portion by being locked inside the engaging convex portion (see, for example, Japanese Patent Laid-Open No. 62-115215).
In addition, there is also known one in which the position where the window glass is fitted into the sash portion is located outside the vehicle as much as possible in order to improve the aerodynamic characteristics of the vehicle (for example, Japanese Patent Publication No.
-69786). In this structure, the side wall portion and the bottom portion inside the vehicle are connected via an inclined portion, and the fin-shaped locking protrusion is formed at the outer end of the inclined portion.

[0003]

However, in the case of holding the grass run by using the above-mentioned conventional fin-shaped locking projections, the workability of attaching the grass run to the sash portion is difficult and unstable. There is a risk that the sealability will deteriorate due to the occurrence of the attached state.

For example, as shown in FIG. 5, one side wall portion 10 is formed.
As an example, the grass run 100 in which 1 is shorter than the side wall part 102 on the other side, and the side wall part 101 on the shorter side is fitted into the concave groove-shaped sash part 2 will be described. First, install the
As shown in, the outer end of the side wall portion 101 on one side (short side) of the pair of side wall portions 101 and 102 is positioned with respect to the opening edge 21 on one side of the sash portion 2, and the whole is slanted. The grass run 100 is inserted into the sash portion 2, and then the side wall portion 102 on the other side is slid with respect to the engaging projection 22 on the opening edge on the other side of the sash portion 2 while the side wall portion 10 on the other side is slid.
Push 2 diagonally. After the locking projection 103 of the side wall 102 on the other side hits the engagement projection 22 as shown in FIG. 6, the locking projection 103 is further projected by applying a stronger pushing force. The mounting work is completed when the vehicle gets over the portion 22 and reaches the inside (see FIG. 5). As the pushing force is applied when overcoming the engaging projection 22, the side wall 102 on the other side is bent as a whole as shown in FIG. 7, while the locking projection 103 is bent. When the above-mentioned engaging projection 22 is overcome by these elastic deformations and the engaging projection 22 is restored to the inside of the engaging projection 22, the engaging projection 22 is locked.

However, in this mounting work,
Since the locking projection 103 abuts on the engaging projection 22 to generate insertion resistance, it is necessary to locally apply a stronger pushing force against the insertion resistance in order to get over the engaging projection 22. In addition, the pushing force is
The larger the approach angle α of 03 (see FIG. 6), the greater the force required. Moreover, it is not possible to visually confirm from the outside whether or not it is locked, and the locking to the engaging convex portion 22 is performed through a relatively slow process of bending / compressing-restoring the locking projection 103. Therefore, it is difficult for an operator who is performing the pushing operation with the above relatively strong pushing force to know whether or not the locked state is achieved. Moreover,
If the protruding length of the locking projection 103 is excessively long or the locking projection 103 itself is easily bent when the engaging projection 22 is passed over, the locking projection 103 is pushed in the pushing process. If the bottom reaches the bottom of the sash section 2 before the 103 gets over the engaging projection 22, the engaging projection 103 remains bent and cannot be pushed any further. There is a possibility that the mounting work may be completed in an incompletely mounted state in which the portion 22 is not locked.

Further, as shown in FIG. 8, the grass run 100 is relatively long along the sash portion 2 of the door D, and there is an insertion resistance due to the locking projection 103, so that the mounting work is locally performed. Therefore, it is inevitable that the pushing force P is applied and the mounting is performed little by little. For this reason, the installation work efficiency is lowered, and when the above-mentioned incompletely installed state partially occurs, the incompletely installed state is propagated in the longitudinal direction, which may impair the sealing property.

The present invention has been made in view of such circumstances, and an object of the present invention is to surely attach the sash portion in a predetermined holding state while promoting the efficiency of attachment work. To do so.

[0008]

In order to achieve the above object, the invention according to claim 1 has a bottom portion and a vehicle of this bottom portion in a state in which the sash portion having a cross-sectional shape is recessed. A pair of side wall portions extending outward from the sash portion so as to have a substantially U-shaped transverse cross section from both ends on the inner side and the vehicle outer side, and from the respective tip ends of the pair of side wall portions toward the bottom portion side. A pair of extending seal lips are integrally provided, and an engaging protrusion projecting to the outside of the vehicle is formed at an opening edge of the sash portion on the inside of the vehicle. The engaging protrusion is engaged with the engaging protrusion to prevent the sash from coming off. It is assumed that the car will be run by grass. In this structure, the bottom portion is arranged in the sash portion at a position offset to the vehicle outer side, and the side wall portion on the vehicle outer side is formed to be shorter than the side wall portion on the vehicle inner side in a cross-sectional shape. The side wall portion on the inner side of the vehicle is provided with an inclined portion that extends obliquely from the end portion on the inner side of the vehicle of the bottom portion to the side wall portion on the outer side of the vehicle, and the outside of the sash portion by bending from the outer end of the inclined portion. A sash portion mounting guide portion extending inward, and a concave step portion that is bent from the outer end of the guide portion to the side wall portion outside the vehicle at a substantially right angle and engages with the engaging convex portion. To do. The outer surface of the guide portion is disposed obliquely with respect to the inner and outer directions of the sash portion with the outer end portion of the outer wall portion of the vehicle positioned at the outer edge of the sash portion. Then, when the side wall portion on the vehicle inner side is slidly inserted into the engaging convex portion to be internally fitted, the side wall portion is formed so as to extend flat in a direction substantially the same as the pushing direction. .

In the case of the above construction, since the side wall portion on the outer side of the vehicle is shorter than the side wall portion on the inner side of the vehicle in the mounting work to the sash portion, when inserting the grass run into the sash portion, the side wall portion on the outer side of the vehicle and the following side portion are inserted. By inserting the entire glass run obliquely with respect to the sash portion with the corner portion on the bottom side first, the insertion work is facilitated. Then, by making the above oblique state, the outer surface of the inclined portion of the side wall portion on the inside of the vehicle hits the engaging projection of the sash portion, and by pushing the side wall portion on the inside of the vehicle, the outer surface of the inclined portion is a kind of guide surface. As the inclined portion slides with respect to the engaging convex portion and advances toward the inside of the sash portion, the side wall portion inside the vehicle is bent outward. Then, the guide surface of the guide portion slides on the engaging convex portion following the inclined portion, the side wall portion on the vehicle interior side is smoothly pushed in, and the guide surface is pushed to the outer end position of the guide surface. The concave step portion fits into the combined convex portion. With the fitting of the recessed step portion, the side wall portion on the inside of the vehicle is restored to the inner wall surface side of the sash portion, and the sliding resistance suddenly disappears. By the generation of the collision sound with, the installer can easily and surely recognize that the grass run is in the holding state. Moreover, since the guide surface extends substantially in the same direction as the pushing direction of the side wall portion on the inside of the vehicle, even if the guide surface slides on the engaging projection, It suffices to continue the pushing work to the same extent, and it is not necessary to carry out the pushing work with a locally strong pushing force as in the case where a conventional locking projection hits the engaging projection. For this reason, the pushing work for the mounting work becomes smooth and easy, and since the portion of the range relatively long with respect to the longitudinal direction of the grass run is pushed in at one time, the efficiency of the mounting work can be greatly improved.

According to a second aspect of the present invention, in the side wall portion on the vehicle interior side according to the first aspect of the present invention, the portion from the guide portion to the concave step portion is made thicker than the other portions and is formed in a block. .

In the case of the above construction, the restoring inertial force of the side wall portion on the vehicle interior side when the concave step portion is fitted into the engaging convex portion is increased due to the thickened and lumped shape, and thus the concave step portion is formed. It becomes easier for the operator to confirm the occurrence of the collision sound between the side wall portion inside the vehicle and the inner wall surface of the sash portion when the portion is fitted. In addition, the grass run is held more reliably by fitting the concave step portion and the engaging convex portion.

According to a third aspect of the present invention, the guide surface in the first aspect of the invention extends parallel to the inner wall surface of the sash portion on the vehicle inner side in a state where the glass run is fitted inside the sash portion. To form.

In the case of the above structure, the forming direction of the guide surface is specifically shown. That is, by forming the guide surface so as to extend parallel to the inner wall surface on the vehicle inner side of the sash portion as described above, when the entire grass run is slanted and inserted into the sash portion, the guide surface engages with the convex portion. The direction in which the side wall portion on the inside of the vehicle is pushed in in the state of being in contact with is substantially coincident with the extending direction of the guide surface.

Further, the invention according to claim 4 is the same as claim 1.
In the invention described above, the fitting position of the window glass is offset from the center position of the sash portion in the vehicle interior / exterior direction to the vehicle exterior position to form a flash surface type.

In the case of the above construction, the window glass comes closer to the side wall portion outside the vehicle, and the step difference between the door frame and the window glass becomes smaller and the surface becomes closer to the flush state. As a result, the flash surface is further enhanced and the aerodynamic characteristics of the automobile are improved.

[0016]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a state in which a glass run 1 according to an embodiment of the present invention is attached by being fitted into a sash portion 2.

The sash portion 2 has a groove bottom 20 and both groove walls 21 and 2 which intersect the groove bottom 20 at substantially right angles.
2 is formed into a groove shape as a whole,
The groove wall 21 on the vehicle outer side (left side in FIG. 1) is formed to have a relatively shallow depth, and the groove wall 22 on the vehicle inner side (right side in FIG. 1) is formed to be relatively deep. The groove wall 21 on the outer side of the vehicle
On the outer end side (the lower end side in FIG. 1) of the vehicle, the opening edge is slightly curved inwardly of the vehicle to form an engaging portion 21a, and the groove edge 22 of the vehicle inner side is open to the vehicle outer side. Projecting engagement protrusion 22a
Are formed. The window glass 3 is arranged so as to be fitted into the sash portion 2 at a position offset to the vehicle outer side as much as possible from the center position of the sash portion 2 in the vehicle interior-exterior direction (the left-right direction in FIG. 1). .

The glass run 1 includes a bottom portion 10, a pair of side wall portions 11 and 12 extending from both ends of the bottom portion 10 in the vehicle interior / exterior direction so as to have a substantially U-shaped cross section, and the side wall portions 11 and 12, respectively. And a pair of seal lip portions 13 and 14 which are curvedly extended from the tip to the side of the bottom portion 10 and are brought into pressure contact with the window glass 3, and these are integrally molded of synthetic resin. The bottom portion 10 is formed to be considerably shorter than the width of the groove bottom 20 of the sash portion 2 in the vehicle interior / outside direction, and the bottom portion 10 is offset and positioned so as to contact the groove wall 21 on the vehicle exterior side.

The side wall portion 11 on the outer side of the vehicle extends along the groove wall 21 from the outer side end of the bottom portion 10, and the outer surface of the outer end of the side wall portion 11 is in close contact with the periphery of the engaging portion 21a to prevent it from coming off. A locking portion 11a having a function is formed.

The side wall portion 12 inside the vehicle is the bottom portion 10
The slanted portion 1 extending obliquely from the vehicle inner side end to the groove wall 22.
5, a guide portion 16 extending from the outer end of the inclined portion 15 along the groove wall 22, and a concave step portion 17 that is bent in a crank shape from the guide portion 16 and faces the groove wall 22 facing each other. And a crank-shaped portion 18 that forms The side wall portion 12 on the inner side of the vehicle is formed thicker as a whole than the bottom portion 10 and the side wall portion 11 on the outer side of the vehicle. Among the side wall portions 12, the guide portion 16 extends from the side of the inclined portion 15 to the side of the crank-shaped portion 18. Is formed so that the range up to is thicker than other parts. The guide portion 16 has a guide surface 16a at the time of mounting work on the outer surface side thereof,
The guide surface 16a is continuously bent from the outer surface of the inclined portion 15 and is fitted inside the sash portion 2 so that the groove wall 2
2 extends substantially parallel to the wall surface and flat. The crank-shaped portion 18 is bent at a substantially right angle from the outer end of the guide portion 16 to the outer side of the vehicle and further bent from a position offset by a predetermined dimension from the outer side of the vehicle to the tip of the side wall portion 12 on the inner side of the vehicle. This crank-shaped portion 18 extends toward the side.
A concave step portion 17 having a depth corresponding to the protruding dimension of the engaging convex portion 22a is formed on the outer surface side of the guide surface 16a from the outer end position of the guide surface 16a.

Further, the outer surface 11b at the outer end of the vehicle side wall portion 11 is formed so as to be smoothly curved toward the window glass 3 from the opening edge of the groove wall 21. The flash surface is formed by smoothly continuing from the outer surface of the sash portion 2 to the outer surface of the window glass 3. Further, from the outer surface 11b of the outer end portion of the vehicle exterior side wall portion 11 to the vehicle interior seal lip portion 1
4 is formed so that the shape extending from the outer surface 14b to the outer surface 14b is smoothly curved toward the inside of the vehicle, so that even when the window glass 3 is in the open state, the portion exposed to the outside of the glass run 1 is made into a flash surface. Is designed.

Reference numeral 10a in FIG. 1 is a fin-shaped support piece. This support piece 10a extends obliquely from the root of the inclined portion 15 on the bottom 10 side to the groove wall 22 side, and the tip abuts on the groove wall 22. This helps the bottom part 10 to be positioned at a predetermined position. Also, in the figure, 14a is a fin portion, and this fin portion 14a is a vehicle interior seal lip portion 14a.
On the contrary, it extends inside the vehicle to shield the boundary between the grass run 1 and the sash portion 2.

Next, a procedure for attaching the glass run 1 having the above-mentioned configuration to the sash portion 2 will be described.

In the state before the glass run 1 is attached to the sash portion 2, both side wall portions 11 and 12 are separated from each other with the both end portions of the bottom portion 10 inward and outward of the vehicle being as starting points and opened outward. The side walls 11 and 12 which are molded are fitted in the sash portion 2 which is narrower than the gap in the molded state, so that the side walls 11 and 12 are more closely adhered to the groove walls 21 and 22, respectively, to improve the holding property. There is.

Then, the grass run 1 is added to the sash portion 2
As shown in FIG. 2, first, the grass run 1 is placed inside the sash portion 2 in a state in which the corner portion composed of the bottom portion 10 and the side wall portion 11 is at the beginning and the whole is inclined with respect to the sash portion 2. The side wall 11 and the locking portion 11a.
Is fitted in the engaging portion 21a of the sash portion 2 and is positioned. At the time of this insertion, the bottom portion 10 is attached to the sash portion 2
Since it is formed to be much shorter than the inner width of the groove bottom 20 of FIG.
Since it is formed to be shorter than the side wall portion 12 on the inside of the vehicle, the above insertion work can be easily performed even if the grass run 1 is inserted in a state where the whole is inclined. As a result of this inserting operation, the outer surface of the inclined portion 15 of the side wall portion 12 on the vehicle interior side is brought into contact with the engaging convex portion 22a of the sash portion 2.

Next, when the tip end of the side wall portion 12 on the inner side of the vehicle is pushed in the direction of the arrow in FIG. 2, the outer surface 15a of the inclined portion 15 slides on the engaging convex portion 22a, so that the side wall. The part 12 advances to the back, and the side wall part 12 is guided to the outer surface 15a of the inclined part 15 so that the guide surface 16a of the guide part 16 continues.
It smoothly rides on and comes into contact with 2a. In the course of this riding, the inclined portion 15 becomes the engaging convex portion 22a.
As it slides with respect to the side wall portion 12 on the inside of the vehicle, the seal lip portions 13, 1 start from the connection portion with the bottom portion 10 as a starting point.
4 is bent so as to rotate toward the side where the interval is narrowed, and accordingly, the reaction force of pressing the side wall portion 12 against the engaging convex portion 22a increases and the sliding resistance gradually increases. The surface that slides with respect to the engaging convex portion 22a moves from the outer surface 15a of the inclined portion 15 to the guide surface 16a, so that the extending direction of the outer surface of the side wall portion 12 with respect to the pushing direction is substantially the pushing direction. Since it changes to the same direction, the sliding resistance does not increase any more and is kept at the same sliding resistance as the sliding resistance immediately before moving to the guide surface 16a. Therefore, without increasing the pushing force, the side wall portion 12 is smoothly pushed into the sash portion 2 by applying the same pushing force as the pushing force until then, and the side wall portion 12 exceeds the outer end position of the guide surface 16a. As a result, the concave step portion 17 is fitted inside the engaging convex portion 22a, and the grass run 1 is brought into a retained state in which it is prevented from coming off, and the mounting operation is completed.

At the time of this fitting, the crank-shaped portion 18 is struck against the engaging convex portion by the pressing reaction force based on the bending of the side wall 12, while the bending of the side wall 12 is accompanied by the fitting. Is restored to engage the convex portion 22a.
The force to bend the side wall portion 12 due to the force suddenly escapes, and the sliding resistance (resistance to pushing) is almost eliminated. Therefore, the operator feels that the side wall portion 12 has been securely fitted into the predetermined position due to the feel of the pushing operator due to the abrupt change of the sliding resistance and the tapping sound generated when the pushing is performed. It can be confirmed that the grass run 1 is held by surely preventing the engaging convex portion 22a from coming off.

In short, the corner portion 17a constituted by the guide surface 16a and the concave step portion 17 is fitted inside the engaging convex portion 22a, so that the side wall portion 12 is surely prevented from falling out of the sash portion 2. In addition, the corner 17a can be
Is formed into a fairly thick lump and, in addition, its corners 17a
The guide surface 16a in the process of getting over the engaging convex portion 22a.
Is formed so as to extend in the same direction as the pushing direction so that the pushing resistance does not increase. Therefore, the occurrence of bending or compression of the corner portion 17a itself is substantially eliminated, and the corner portion 17a is substantially eliminated.
Can be engaged with the inside of the engaging convex portion 22a by a restoring force based on elastic deformation of the side wall portion 12 that bends from the side of the bottom portion 10 as a starting point. For this reason, it is possible to reliably eliminate the occurrence of an incompletely attached state that may occur during the locking process in which the locking protrusion 103 (see FIG. 7) of the related art is bent and deformed and then restored to the locked state. You can

Further, in the process in which the corner portion 17a is engaged with the inside of the engaging convex portion 22a as described above, the increase of the pushing resistance is eliminated and the side wall portion 12 is smoothly inserted into the sash portion 2. Therefore, unlike the conventional grass run 100 (see FIG. 8), it is not necessary to locally push the locking projection 103 locally with a relatively strong pushing force P ′ in the pushing process into the sash portion 2, as shown in FIG. As described above, a relatively long range portion of the grass run 1 can be fitted into the sash portion 2 by a single pushing operation of the operator, such as the thumb, to finish the attachment work. Therefore, the efficiency of the mounting work can be significantly improved as compared with the conventional one.

<Other Embodiments> The present invention is not limited to the above-described embodiments, but includes various other embodiments. That is, in the above embodiment,
The glass run 1 is first inserted into the sash portion 2 with the entire body obliquely inserted, and then the vehicle interior side wall portion 12 is pushed obliquely. However, the invention is not limited to this. The bottom wall 20 and the bottom portion 10 may be arranged so as to be parallel to each other, and the glass run 1 may be fitted into the sash portion 2 as it is. Even in this case,
The outer surface 15a of the inclined portion 15 comes into contact with the engaging convex portion 22a, and the side wall portion 12 is pushed in a direction parallel to the groove wall 22 of the sash portion 2, whereby the outer surface 15a is brought into contact with the engaging convex portion 22. Sliding against each other, the side wall portion 12 is bent accordingly and sliding resistance increases. When the guide surface 16a of the guide portion 16 is reached, the increase of the sliding resistance is almost stopped, and the corner portion 17a is fitted to the inside of the engaging convex portion 22a by pushing with the same pushing force up to that point. To do. Therefore, also in this case, it is possible to obtain the same actions and effects as those described in the above embodiment.
