Description

  The present invention relates to a door sash of a vehicle door whose lower end is connected to a door panel and a method for cutting the door sash of a vehicle door.

As a conventional example of a door sash in a vehicle door, for example, there is one disclosed in Patent Document 1.
The door sash 1 of Patent Document 1 has a bag portion (not shown) having a hollow cylindrical cross section, and a weather strip holding portion (weather strip fitting groove 13) on the outer peripheral surface side, and has a glass on the inner peripheral surface side. And a flat buffer member holding portion (not indicated) having a run holding portion (door glass guide groove 12). Since the door sash 1 is formed by roll forming, the cross-sectional shape of the door sash is uniform (identical) at any position in the longitudinal direction at the time of forming.

The door sash 1 cuts the lower end part of the weather strip holding | maintenance part (the bead 7 and the wall 9 of the wall 8) after roll forming.
Since such processing is applied to the lower end portion of the door sash 1, as shown in FIG. 1, the wall 8 (portion excluding the bead 7) and the bottom surface 13a of the weather strip holding portion at the lower end portion of the door sash 1 are provided. It is possible to spot weld the door panel 6. Furthermore, since the bottom surface 13a of the weatherstrip holding portion of the door sash 1 and the surface (not shown) on which the weatherstrip of the door panel 6 is mounted are continuous with almost no step, the weatherstrip is almost at the joint between the door sash 1 and the door panel 6. It is possible to install without gaps.

The door sash 25 includes an upper sash 30 that constitutes a front edge portion and an upper edge portion of the door sash 25, and a side sash 27 that constitutes a rear edge portion and extends in a substantially vertical direction. The upper sash 30 and the side sash 27 are all made of metal.
As shown in FIG. 1, the lower end portion of the upper sash 30 faces the vehicle outer surface of the bulging portion 22, and as shown in FIG. 3, the two surfaces of the bag portion 32 and the front surface of the connecting portion 34 are The bulging portion 22 is welded to the vehicle outer side surface (the surface facing the upper sash 30). Further, as shown in FIG. 1, the lower end portion of the side sash 27 is also opposed to the vehicle outer surface of the bulging portion 22 and is welded to the vehicle outer surface (surface facing the side sash 27) of the bulging portion 22. . A window hole 29 is formed in a portion surrounded by the upper sash 30, the side sash 27, and the upper edge of the bulging portion 22.
A glass run GR formed of an elastic material such as rubber is attached to the inner peripheral surfaces of the upper sash 30 and the side sash 27 over the entire circumference. Further, a slide glass GL having substantially the same shape as that of the window hole 29 is fitted into the window hole 29, and the peripheral portion of the slide glass GL is slidably fitted into the glass run GR as shown in FIG. Yes. Therefore, the slide glass GL can slide in the vertical direction along the upper sash 30 (glass run GR) and the side sash 27 (glass run GR).

  A weather strip WS1 formed of an elastic material such as rubber is hung around a portion of the outer peripheral surfaces of the upper sash 30 and the side sash 27 located above the bulging portion 22. Further, as shown in FIG. 2, the entire outer peripheral surface (front surface 22 a, lower surface, and rear surface) of the bulging portion 22, and a portion positioned above the bulging portion 22 of the outer peripheral surface of the upper sash 30 and the side sash 27, The annular weather strip WS2 that is parallel to the weather strip WS1 and is located on the inner side of the weather strip WS1 is formed in the mounting hole 31 and the bulging portion 22 in which a plurality of engagement pins A are formed in the upper sash 30. It is mounted by fitting into the drilled through hole 22c. When the door 20 is closed, the weather strip WS1 and the weather strip WS2 are brought into elastic contact with the periphery of the door opening 10 of the vehicle body (see FIGS. 2 and 3) to seal between the door 20 and the door opening 10.

Next, the structure of the upper sash 30 will be described in detail.
The upper sash 30 is formed by roll forming or pultrusion as a linear long object having the cross-sectional shape shown in FIGS. 2 and 4 (the cross-section at all positions in the longitudinal direction is uniform), and then bending is performed. Thus, the shape of FIG. 1 is obtained. The upper sash 30 has a hollow cylindrical bag part 32, a flat buffer member holding part 33 extending in the vehicle width direction (with the door 20 closed), a bag part 32, and a buffer member over the entire length of the upper sash 30. A flat connecting portion 34 for connecting the holding portion 33, an inner peripheral ridge (weather strip holding portion) 36 and an outer peripheral ridge (weather) protruding forward from both side edges of the front surface 35 of the buffer member holding portion 33. A strip holding portion 37 and a protrusion (glass run holding portion) 39 projecting rearward from the vehicle outer edge portion of the rear surface 38 of the buffer member holding portion 33 are formed. A weather strip holding groove 40 that fits and holds the inner peripheral side end of the weather strip WS1 is formed between the front surface 35, the inner peripheral ridge 36, and the outer peripheral ridge 37 of the buffer member holding portion 33. A glass run holding groove 41 is formed between the rear surface 38 of the holding portion 33, the protrusion 39 and the bag portion 32 to fit and hold the outer peripheral side end of the glass run GR.
When the upper sash 30 having such a cross-sectional shape is viewed in a direction orthogonal to the buffer member holding portion 33 (arrow B direction), as shown in FIG. The protrusion 36, the outer peripheral protrusion 37, and the protrusion 39 do not overlap the bag portion 32 (shifted in the vehicle width direction).

As described above, the buffer member holding portion 33, the inner peripheral ridge 36, the outer peripheral ridge 37, and the ridge 39 are integrally formed on the upper sash 30 by roll forming or pultrusion as described above. However, as shown in FIGS. 3 and 4, the buffer member holding portion 33, the inner peripheral protrusion 36, the outer peripheral protrusion at the lower end of the upper sash 30 (the portion facing the bulging portion 22 of the inner panel 21). Since the side edge portions on the buffer member holding portion 33 side of the strips 37, the protrusions 39, and the connecting portions 34 are cut after roll molding (or after pultrusion molding), the lower end portion of the upper sash 30 is connected to the bag portion 32. Only a part of the part 34 is left.
When the lower end portion of the upper sash 30 is cut so as to have such a shape, as shown in FIG. 2, the front surface of the connection portion 34 and the front surface 22a of the bulging portion 22 are continuous without any step in plan view. Therefore, even at the joint portion between the upper sash 30 and the bulging portion 22, the inner peripheral end of the weather strip WS <b> 2 can be brought into contact with the front surface of the connection portion 34 and the front surface 22 a of the bulging portion 22 without any gap.

Next, the cutting procedure of the lower end portion of the upper sash 30 will be described with reference to FIGS.
The cutting operation is performed using the jig 50 and the cutting tool 60.
A groove 51 and a groove 52 linearly extending in the longitudinal direction are formed on the upper surface of the jig 50, and a support protrusion 53 whose upper surface forms a flat surface is formed between the groove 51 and the groove 52. It is. Further, an inclined support surface 54 that extends linearly in the longitudinal direction and a vertical surface 55 that is continuous with the inclined support surface 54 are formed on the upper surface of the jig 50. Further, the entire portion closer to the groove 51 than the inclined support surface 54 at one end in the longitudinal direction of the jig 50 is notched, and the end surfaces of the notch 56 are first plane 57 and second plane orthogonal to each other. 58.
The cutting tool 60 is a member whose cross-sectional shape (planar shape) is substantially L-shaped, and the entire lower surface thereof is a tooth portion 61. Furthermore, a first sliding contact plane 62 parallel to the first plane 57 of the jig 50 and a second sliding contact plane 63 parallel to the second plane 58 of the jig 50 are formed on the outer surface of the cutting tool 60. It is.
Note that the notch 56 and the cutting tool 60 of the jig 50 have the same length as that of the portion facing the bulging portion 22 of the upper sash 30 (see FIG. 1), but for convenience, in FIGS. The figure is shorter than that.

In order to perform the cutting operation, first, as shown in FIG. 6, the front surface of the upper sash 30 is directed downward and the inner peripheral ridge 36 and the outer peripheral ridge 37 are fitted into the groove 52 and the groove 51 of the jig 50, respectively. Match. Then, the front surface (jig contact surface) 35 of the buffer member holding portion 33 is supported by the upper surface of the support protrusion 53, and the front surface (jig contact surface) of the connection portion 34 and the bag portion 32 is supported by the inclined support surface 54. Further, the inner side surface (jig contact surface) of the bag portion 32 comes into contact with the vertical surface 55.
When the upper sash 30 is supported by the jig 50 in this way, as shown in FIGS. 5 and 6, the cutting tool 60 is moved immediately above the notch 56 of the jig 50 (the first sliding contact plane 62 and the first slidable plane 62 and The first plane 57 and the second sliding contact plane 63 and the second plane 58 are positioned on the same plane). In this state, when the cutting tool 60 is linearly moved downward (in the direction of the arrow in FIGS. 5 and 6), the cutting tool 60 uses the first sliding contact plane 62 and the second sliding contact plane 63 as the first plane 57 of the jig 50. And the second flat surface of the upper sash 30 by the tooth portion 61, the buffer member holding portion 33, the inner peripheral ridge 36, the outer peripheral ridge 37, the ridge 39 and the connecting portion 34 at the lower end of the upper sash 30. The side edge part on the buffer member holding part 33 side is cut once (see FIG. 7).

  As described above, the upper sash 30 according to the present embodiment has the buffer member holding portion 33 and the inner peripheral side bump when viewed from the direction orthogonal to the buffer member holding portion 33 (the arrow B direction in FIG. 4). Since the strip 36, the outer peripheral ridge 37, and the ridge 39 are cross-sectional shapes that do not overlap the bag portion 32, the buffer member holding portion 33, the inner peripheral ridge 36, the outer peripheral ridge 37, and the ridge 39 are cut by the cutting tool 60. And the lower end part of the side edge part by the side of the buffer member holding | maintenance part 33 of the connection part 34 can be cut | disconnected without damaging the bag part 32 by one linear cutting operation | work. Therefore, processing (cutting) of the lower end portion of the upper sash 30 is easier than in the prior art in which a plurality of operations are required to process the lower end portion of the door sash.

  Moreover, during the cutting operation, the front surface 35 of the buffer member holding portion 33 of the upper sash 30, the connection portion 34 and the front surface of the bag portion 32, and the inner side surface of the bag portion 32 are connected to the upper surface of the support protrusion 53 of the jig 50, and the inclined support surface. 54 and the vertical surface 55 respectively support the cutting operation in a stable state.

  Further, the upper sash 30 of the present embodiment has an end on the buffer member holding portion 33 side of the buffer member holding portion 33, the inner peripheral ridge 36, the outer peripheral ridge 37 and the ridge 39 and the connecting portion 34 from the lower end thereof. Although the portion is cut off, most of the connecting portion 34 is left without being cut off. For this reason, the inner side surface of the bag portion 32 and the front surface of the connecting portion 34 can be welded to the outer side surface of the bulging portion 22 (the surface facing the upper sash 30), so the lower end portion of the upper sash 30 and the bulging portion 22 (Inner panel 21) can be firmly joined.

Although the present invention has been described based on the above embodiments, the present invention is not limited to the above embodiments, and can be implemented with various modifications.
For example, as shown in FIG. 2, the connection portion 34 is exposed through the gap between the bag portion 32 and the glass run holding portion 39 when viewed from the inner peripheral side of the door sash 30, and therefore the cutting direction of the cutting tool 60 is indicated by an arrow. It is not limited to the B direction. That is, for example, the cutting tool 60 is linearly moved in a direction perpendicular to the connecting portion 34 and is brought into contact with the connecting portion 34 through the gap between the bag portion 32 and the glass run holding portion 39. Can be cut at once.
Furthermore, in the said embodiment, the side edge part by the side of the buffer member holding | maintenance part 33 side of the connection part 34 not only the buffer member holding | maintenance part 33, the inner peripheral side protrusion 36, the outer peripheral side protrusion 37, and the protrusion 39 by the cutting tool 60 However, it is also possible to implement in a mode in which only the buffer member holding portion 33, the inner peripheral ridge 36, the outer peripheral ridge 37, and the ridge 39 are cut.
Alternatively, the lower end portion of the side sash 27 may have the same cross-sectional shape as the upper sash 30, and the lower end portion of the side sash 27 may be cut using the jig 50 and the cutting tool 60 in the same manner as described above.
