BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner piece grass run mounting structure.

[0002]

2. Description of the Related Art As a conventional glass run mounting structure for a corner piece, there is, for example, one shown in FIGS. 7 to 10 (for a similar technique, see Japanese Patent Laid-Open No. 61-16124). In the following description, the passenger compartment side is referred to as “inner side”,
The outside of the vehicle will be described as "outer side".

FIG. 7 shows a hard top vehicle, and its door 1 has a sashless structure composed of a door outer panel 2 and a door inner panel 3. A waist opening 4 is formed in the upper part of the door 1, and an outer reinforcement 5 and an inner reinforcement 6 which are respectively joined to the door outer panel 2 and the door inner panel 3 are provided in the waist opening 4. . Further, inside the door 1, a door glass 7 that can be raised and lowered from the waist opening 4 is provided.

Further, at the front end position of the waist opening 4, a corner piece 8 of a substantially triangular shape in which the door inner panel 3 is formed to extend upward in order to mount the door mirror M.
Is provided. A glass run bracket 10 is joined to the rear side portion 9 of the corner piece 8 from the outer side, and a fitting groove 11 that opens rearward is formed between the glass run bracket 10 and the rear side portion 9. At the lower end portion of the glass run bracket 10 located inside the waist opening 4, there is a connecting surface 12 in a state where the outer reinforcement 5 and the inner reinforcement 6 facing each other in the waist opening 4 are connected in the width direction of the door 1. Has been formed. A circular mounting hole 13 is formed in the connecting surface 12. Further, the oblique side portion 14 of the corner piece 8 has a shape of being bent to the outer side with a constant width, and the front side of the oblique side portion 14 is provided with an extension portion 16 which is directly extended to the front side through a step portion 15. Has been formed.

Then, the fitting groove 11 of the corner piece 8 is formed.
Inside, there is a guide groove 17 that elastically contacts the front edge of the door glass 7.
A glass run 18 (see FIG. 9) is attached. A weather strip portion 19 attached to the oblique side portion 14 of the corner piece 8 and the like is integrally formed from the upper end of the glass run 18.

Engaging pieces 30 that engage with both ends of the fitting groove 11 are formed on the side surface of the grass run 18 above the waist opening 4. In addition, the lower side surface portion 21 located in the waist opening 4 of the grass run 18
Is wider than the upper portion in the width direction of the door 1, and a tapered portion 22 is formed at the lower end of the side surface portion 21 in a divergent shape. Further, the front surface portion 23 at the lower end portion of the grass run 18 is formed with a projection portion 24 which is inserted into the mounting hole 13 of the connecting surface 12 at an intermediate position thereof. Therefore, the grass run 18 is the corner piece 8
The mounting span d extends vertically from the upper end of the rear side portion 9 to the mounting hole 13. The glass run 18 is an injection-molded product of soft rubber, and if burrs are left on the protrusions 24 during manufacturing, it will not be possible to insert the burrs into the mounting holes 13. Therefore, deburring of the protrusions 24 is particularly careful. Need to do.

[0007]

However, in such a conventional technique, it is troublesome to insert the protrusion 24 formed at the lower end of the glass run 18 into the mounting hole 13 of the connecting surface 12. However, it has been a cause of reducing the efficiency of the work for mounting the grass run 18, and therefore improvement thereof is desired.

Further, since it is necessary to completely remove the burr on the protrusion 24, the workability in manufacturing the glass run 18 is also disadvantageous.

Furthermore, since the protrusion 24 is formed at an intermediate position in the lower end of the grass run 18, the protrusion 2
The shape of the portion below 4 is not stable, and in some cases, as shown in FIG.
Like the guide groove 17 of the door glass 7 and the glass run 18
There is a risk that the normal operation of raising the door glass 7 may be hindered. Therefore, as a measure for that,
For example, it is necessary to manufacture only the lower end portion of the grass run 18 with hard rubber, which makes the manufacturing of the grass run 18 more difficult.

In addition, since the mounting state of the glass run 18 is affected by the position of the mounting hole 13 formed on the connecting surface 12 of the glass run bracket 10, strict positional accuracy is required for forming the mounting hole 13, and the glass run is required. This is a cause of lowering the yield when the bracket 10 is press-molded.

The present invention has been made by paying attention to such a conventional technique, and it is easy to attach and manufacture the grass run, and the shape of the lower end portion of the grass run is stabilized, and the yield of the grass run bracket is improved. The present invention provides a corner piece grass run mounting structure capable of

[0017]

According to the first aspect of the present invention, since the recess formed by the hook portion of the grass run is engaged with the lower end of the connecting surface of the grass run bracket to be mounted, the projection is formed in the mounting hole as in the conventional case. The work is easier than when inserting. Further, since it is not necessary to deburr the grass run precisely, the manufacturing work of the grass run itself becomes easy. Further, since the hook portion at the lower end of the front surface portion of the grass run is engaged with the lower end of the connecting surface, the shape of the lower end portion of the grass run is stable, and the raising operation of the door glass can be reliably performed. Since the hook portion at the lower end of the front surface of the grass run is engaged with the lower end of the connecting surface, the span of attachment of the grass run is increased, the rigidity of attachment of the grass run is increased, and the support performance of the door glass is improved. Furthermore, since it is not necessary to form a mounting hole in the glass run bracket,
The yield of grass run brackets is also improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to FIGS.
It will be described based on. The same parts as those in the prior art are designated by the same reference numerals, and a duplicate description will be omitted.

In this embodiment, an upward hook portion 27 is formed at the lower end of the front surface portion 23 of the grass run 26, and the hook portion 27 and the front surface portion 23 have a U-shaped cross section (note that a V-shaped shape is also acceptable). 2) is formed. Then, the recess 28 is engaged with the lower end of the connecting surface 12 of the grass run bracket 25, whereby the grass run 26
Is attached to the connecting surface 12. The width of the hook portion 27 is the same as the width of the grass run 26, and the side surface of the hook portion 27 and the side surface portion 21 at the lower end portion of the grass run 26 are flush with each other.

Further, vertical ribs 29 and 30 having lower ends continuous with the tapered portion 22 are formed on the outer and inner side surfaces 32 of the glass run 26, respectively. The side surfaces of the vertical ribs 29, 30 are in contact with the outer reinforcement 5 and the inner reinforcement 6 as “opposing surfaces” in the waist opening 4, respectively.

Next, the attachment of the weather strip portion 31 to the hypotenuse portion 14 of the corner piece 8 will be described.
A groove portion 32 having a cross-sectional shape corresponding to the oblique side portion 14 is formed at a portion of the weather strip portion 31 corresponding to the oblique side portion 14 (see FIG. 5), and the oblique side portion 14 is engaged in the groove portion 32. There is. The formation of the groove portion 32 ends at a position corresponding to the step portion 15 at the front end of the hypotenuse portion 14, and the step portion 1 is formed.
A corresponding surface 33 is formed at a position corresponding to 5. Then, a notch 34 for confirming the state of the corresponding surface 33 is partially formed in the vicinity of the corresponding surface 33. Further, a shielding rib 35 is formed on the corresponding surface 33, and the lower end of the shielding rib 35 continuously extends along the lower surface of the weather strip portion 31 in front of the corresponding surface 33, to some extent. Is absorbed by the lower surface of the weather strip portion 31 as it is and ends. The advantages of this embodiment are listed below.

Improvement of workability of attaching the glass run 26: In this embodiment, the concave portion 28 formed by the hook portion 27 of the glass run 26 is connected to the connecting surface 1 of the glass run bracket 25.
Since the structure is mounted by engaging with the lower end of 2, the work is easier and the workability of mounting the grass run 26 is improved as compared with the case where the protrusion is inserted into the mounting hole as in the conventional case.

Improvement of manufacturing workability of the glass run 26 : As described above, the glass run 26 of this embodiment can be mounted by the engagement of the concave portion 28 and the connecting surface 12, so that the glass run 26 is injection molded. The deburring of the glass run 26 does not need to be performed as strictly as in the conventional case when the glass is manufactured. Therefore, the manufacturing work of the grass run 26 itself is facilitated.

Prevention of rattling of the glass run 26: The recess 28 formed by the hook 27 has a U-shaped cross section, and the lower end of the connecting surface 12 engages with the lowest point 28a of the recess 28 (see FIG. 3). Rattling of the lower end of the grass run 26 in the front-rear direction is reliably prevented.

Shape stability of lower end of glass run 26 : Hook portion 2 formed at lower end of front surface 23 of glass run 26
7 is engaged with the lower end of the connecting surface 12, the shape of the lower end of the glass run 26 is stable, the door glass 7 and the lower ends of the glass run 26 do not interfere, and the raising operation of the door glass 7 is ensured. Can be done. Further, since the width of the hook portion 27 is the same as the width of the grass run 26, the rigidity of the lower end portion of the grass run 26 is increased by the formation of the hook portion 27, and the width between the taper portions 22 is prevented from being narrowed. . Further, since the vertical ribs 29 and 30 whose lower ends are continuous with the tapered portions 22 are formed on the side surface portions 21 of the grass run 26, the rigidity of the lower end portion of the grass run 26 can be increased by the formation of the vertical ribs 29 and 30. Moreover, since the side surfaces of the vertical ribs 29 and 30 are in contact with the outer reinforcement 5 and the inner reinforcement 6, this also prevents the lower end of the glass run 26 from being deformed to the outer side or the inner side.

Yield improvement of glass run bracket 25:
The glass run bracket 25 of this embodiment does not need to be provided with a "mounting hole" that requires strict positional accuracy as in the conventional case, so that the yield at the time of press molding the glass run bracket 25 is improved.

Expansion of mounting span D: Also, glass run 2
6 has a structure in which the hook portion 27 at the lowermost end position is engaged with the lower end of the connecting surface 12, the mounting span D between the hook portion 27 (strictly speaking, the lowest point 28a) and the upper end of the grass run 26 (see FIG. 1) is increased, and the mounting rigidity of the grass run 26 is increased.

Waterproofness of the weather strip portion 31: Since the shielding rib 35 is formed on the corresponding surface 33, even if a gap S is formed between the corresponding surface 33 and the step portion 15, the outer side of the gap S is shielded. It can be covered with the rib 35. Therefore,
It is possible to prevent rainwater and the like from entering the inner side through the gap S. Further, even if the gap S is formed in this manner, the waterproof property is maintained, so that the gap S for absorbing the variation between the oblique side portion 14 and the weather strip portion 31 can be positively provided. . Therefore, it is not necessary to pay much attention to the attachment error and the forming error of the weather strip portion 31, so that the workability of attaching the weather strip portion 31 and the productivity are improved. Moreover, covering the outer side of the gap S with the shielding rib 35 is also effective in preventing wind noise when the vehicle is traveling.
