Description

[Detailed description of the invention] a. Industrial application field The invention relates to a door sash mounting structure.

b. Conventional technology Conventional door sash mounting structures include, for example,
Some are shown in the figure. This car door sash
Reference numeral 51 denotes a U-shaped cross section, and is attached to a pillar portion of a panel door 54 including a door inner panel 52 and a door outer panel 53. For this reason, a sash bracket 55, which is fastened and fixed to the panel door 53 with a screw or the like, is fixed to the upper part of the door sash 51, and a plurality of engaging pieces 56, which are partially cut and raised, are provided on the opposite side surface. It is provided at intervals. On the other hand, the flange portions of the door inner panel 52 and the door outer panel 53 located on the door sash 51 side are formed in open cross-section structures facing each other, and the terminal thereof is engaged with the engagement piece 56 of the door sash 51. A plurality of notches 57 are provided correspondingly.

In the door sash mounting structure,
The door sash 51 is disposed between the door inner panel 52 and the door outer panel 53, and each engagement piece 56 is positioned by being inserted into the corresponding notch 57, respectively. Thereafter, when the sash bracket 55 is tightened and fixed by a screw or the like (not shown), the door sash 51 is attached to the panel door 54.

c. Problems to be Solved by the Invention However, in the above-described conventional mounting structure, the door sash 51 is positioned and held by the engaging action of the engaging piece 56 and the notch 57, so that the door sash 51 in the vertical direction is
The positioning of the door sash 51 was not performed reliably, and there was a risk that the door sash 51 would fall when tightening a screw or the like. In addition, since the flange ends of the door panels 52 and 53 provided with the notches 57 contact and press the cut-and-raised portion of the engagement piece 56 due to the load in the front-rear direction, there is a problem that rust is easily generated in the portion. there were.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a door sash mounting structure capable of solving the above-mentioned disadvantages.

d. Means for Solving the Problems In order to solve the problems of the prior art, according to the present invention, in the mounting structure of the door sash, one end of which is mounted via a bracket to a pillar portion of a door panel having an open cross-sectional structure, While providing a plurality of semi-arc-shaped projections on the opposite side surface of the door sash at intervals in the vertical direction,
The flange portion of the door panel is provided with notches whose lower side is formed substantially in an L-shape, and the door sash is positioned by engaging the projections with these notches.

e. Embodiment Hereinafter, the present invention will be described in detail based on the illustrated embodiment.

1 to 5 show one embodiment of a door sash mounting structure according to the present invention. Referring to FIG. 1, reference numeral 1 denotes a panel door of an automobile. The panel door 1 includes a door inner panel 2 and a door outer panel 3 made of sheet metal. The pillar portion 4 of the panel door 1 has an inner peripheral end formed in an open cross-sectional structure, and is formed by bending the inner panel 2.
The funnel parts 2a, 3a of the outer panel 3 are arranged facing each other with a space therebetween.

Further, a door sash 5 for holding a door glass is attached to a pillar portion 4 of the panel door 1 via a sash bracket 6. The door sash 5 is formed in a U-shaped cross section, and one end of a sash bracket 6 is fixed to the upper part of the panel mounting surface 5a by welding.
Further, a plurality of semicircular projections 7 for positioning are provided on the opposite side surfaces 5b of the door sash 5 at intervals in the vertical direction, and these projections 7 are embossed as shown in FIG. Are formed integrally on the outer surface of both side surfaces 5b. The sash bucket 6 is formed in the shape of a crank in which both ends of a single plate-like member are bent at right angles in opposite directions in the vertical direction, and a mounting hole for a screw 9 screwed with a nut 8 is formed at the upper end. 10 are drilled.

On the other hand, a plurality of notches 11 that engage with the projections 7 of the door sash 5 are provided at corresponding positions at the ends of the flange portions 2a and 3a of the door inner panel 2 and the door outer panel 3, respectively. As shown in FIG. 4, these notches 11 are cut so that the upper side is inclined obliquely upward, so that the projection 7 of the door sash 5 can be easily incorporated. The lower side of the notch 11 is formed substantially in an L-shape, and the projection 7
a performs the positioning operation of the door sash 5 in the front-rear direction,
The lower wall 11b is configured to perform a vertical positioning operation of the door sash 5.

Next, a procedure for mounting the door sash 5 having the above configuration will be described. First, the lower end of the sash bracket 6 is applied to the upper part of the panel mounting surface 5a of the door sash 5 and fixed by welding. Next, the door sash 5 is arranged between the flange portions 2a, 3a of the door inner panel 2 and the door outer panel 3, and each projection 7 is inserted into the corresponding notch 11, thereby forming the door sash 5 on the back wall 11a and the lower wall 11b. Engage. Thus, the door sash 5 is held by the flange portions 2a, 3a of the door inner panel 2 and the door outer panel 3 in a state where the door sash 5 is positioned in the front-rear direction and the vertical direction. In this state, the upper end of the sash bracket 6 is brought into contact with a predetermined position of the door inner panel 2 and the screw 9 is attached to the mounting hole.
The door sash 5 is attached to the pillar portion 4 of the panel door 1 when the nut 8 is screwed into the screw portion of the screw 9 and then tightened and fixed (see FIG. 2).

As mentioned above, although one Example of this invention was described, this invention is not limited to the said Example, Various modifications and changes are possible based on the technical idea of this invention.

f. Effects of the Invention As described above, the door sash mounting structure according to the present invention provides a plurality of semi-circular arc-shaped projections on the opposing side surfaces of the door sash at intervals in the vertical direction, and on the flange portion of the door panel. The lower side is provided with notches formed in a substantially L-shape, and the projection is engaged with these notches so as to position the door sash. Therefore, the door sash can be reliably positioned in the vertical direction. As a result, there is no possibility that the door sash will fall from the door panel when the screw or the like is tightened, and the workability can be improved. Further, in the mounting structure of the present invention, since the positioning projection is formed in a semicircular arc shape, even if the flange portion terminal of the door panel comes into contact with the above projection due to the load in the front-rear direction and presses the same. The protrusions are less likely to be damaged,
It has the advantage that it is less likely to cause rust.
