Description

[Detailed Description of the Invention] The present invention relates to a sliding door opening/closing device on the side of an automobile body.

Sliding doors in conventional automobiles slide along guide rails protruding from the side panels of the vehicle body or along guide rails in grooves formed in the side panels. A cover must be provided to hide the rail, and even if this method is used, there are still problems in that the appearance is unsightly and the work is complicated.

The present invention attempts to solve these problems by providing a door guide rail using the seam of a lid member such as a bonnet at the front end of the vehicle body or a trunk lid at the rear end. The purpose of the present invention is to provide a sliding door opening/closing device for an automobile that has a simplified structure and maintains its aesthetic appearance.

For this reason, the sliding door opening/closing device for an automobile according to the present invention is arranged along the upper edge of the side panel of the vehicle body, which is opposite to the side edge when the lid member pivotally attached to the end of the vehicle body is closed. A guide rail is provided inside, and the base end of the door guide hinge lever is attached to the door provided in the side opening of the vehicle body, and a roller pivotally supported on the inner end of the door guide hinge lever engages with the guide rail. A roof side guide rail and a side sill guide rail are provided along the upper and lower edges of the side opening of the vehicle body, respectively, and a sash rail is also provided on the vertical sash portion of the door. , a lower roller assembly comprising a plurality of rollers is engaged across the roof side guide rail and the sash rail, and is supported by an arm pivotably attached to the lower part of the door so as to be swingable laterally. is configured to engage with the side sill guide rail to slide the door open and close, and the lid member also serves as a cover that covers the guide rail when the door is closed.

Hereinafter, an embodiment of the sliding door opening/closing device for an automobile according to the present invention will be explained with reference to the drawings. Fig. 1 is a perspective view showing the sliding front door in an open state, and Fig. 2 is a perspective view showing the opening/closing state of the front door. Figure 3 is a partial cross-sectional view taken along the line ■-■ in Figure 2, Figure 4 is a partial cross-sectional view showing the
A partial perspective view showing the details of the ■ part in the figure, FIG. 5 is a partial view showing the arrangement of the roof side guide rail and the sash rail, and FIG. 6 is a roller that engages with the roof side guide rail and the sash rail.

The front door 1 can be slid open and closed by engaging with the front door 1.

Furthermore, as shown in FIG. 1, a roof side guide rail 11 and a side sill guide rail 12 for guiding the front door 1 are arranged along the upper and lower edges of the opening of the vehicle body having the front door 1, respectively. A sash rail 13 is also provided on the vertical sash portion of the front door 1 in correspondence with the roof side guide rail 11.

Then, as shown in FIG. 5.6, a plurality of rollers 14a
, 14b and a roller holding member 14c is mounted across the roof side guide rail 11 and the sash rail 13, one roller 14a engages with the roof side guide rail 11, and the other roller 14b engages with the roof side guide rail 11. is engaged with the satchel rail 13.

As shown in FIG. 6, the roller holding member 14c has a universal joint 14d between the support portion of one roller 14a and the support portion of the other roller 14b. In combination with the fact that the lower roller 15 that engages with the side sill guide rail 12 is supported by the arm 16 that is pivotally attached to the lower part of the front door 1 so as to be able to swing laterally, the front door 1 is , as shown in FIG. 7, a tilting motion around the universal joint 14d can be performed at the beginning of opening the door or at the end of closing the door.

That is, when the front door 1 is tilted, as shown in FIG.
It is swung out to the side by the rotation.

Further, as shown in FIG. 2, the rear ends of the guide rail 3 and the side sill guide rail 12 are each curved inward, so that the front door 1 can be closed without protruding laterally from the outer surface of the vehicle body. Ru.

Since the sliding door opening/closing device for an automobile according to the present invention is constructed as described above, when opening the front door 1, the front door 1 can be freely moved by swinging the door guide hinge lever 7 and the arm 16 laterally. While performing a tilting operation around the joint 14d, each roller 10, 15 is guided along the curved rear end of the guide rail 3 and the side sill guide rail 12, and as a result, the front door 1
The opening can be opened smoothly without interference from the front edge of the vehicle body opening (entrance/exit) or the fender panel.

Figures 8 to 13 show the main parts of a device as a second embodiment of the present invention, and Figure 8 shows a roller assembly that engages with the roof side guide rail and the sash rail, corresponding to Figure 6. 9 is a perspective view of the roof side guide rail, FIG. 10 is a perspective view of the roller assembly,
FIG. 11 is a perspective view of the sash rail, FIG. 12 is a partial sectional view showing the lower roller engaged with the side sill guide rail, and FIG. 13 is a perspective view of the lower roller.

As shown in FIGS. 8 to 11, in this second embodiment, the roller assembly 14 consisting of a roller 14a that engages with the roof side guide rail 11 and a roller 14b that engages with the sash rail 13 is greatly simplified. , and the rear end portion 11a of the roof side guide rail 11 is curved inward,
As a result, the front door 1 is angled outward in the initial stage of opening.

In FIG. 8, the sash rail 13 and the door sash 1a supporting the same are shown twisted approximately 90 degrees in a horizontal state.

Further, in this second embodiment, as shown in FIG. 12.13, the lower roller 15 on the door side that engages with the side sill guide rail 12 on the vehicle body side is provided to rotate around a horizontal axis 15a. There is.

That is, the lower roller 15 is supported via a horizontal shaft 15a at the tip of an arm 16 that is pivotally attached to the inside of the front door 1 by a vertical pin 16a.
