Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to an additional structure of a door window regulator suitable for a rear door of a hardtop automobile.

"Prior Art" As shown in Figures 1 and 2, the rear door of an automobile (
10), the door body (11) has a tire cutout (1).
2), it is not easy to avoid this rear tire gouge (12) and store the door window (13) inside the door body (11). Since there is no door sash in a car and it is not possible to install a vision bar, the area of the door window (13) is large, and when it is stored inside the door body (11), I try to lower it while drawing a complicated trajectory.

Examples of door window regulators used in such cases include those shown in FIGS. 3 to 5 of the ``Nisan Laurel Model C31 Vehicle Maintenance Manual J''.

That is, the door window regulator (20) includes a door window support rail (21) attached to the lower edge of the door window (13), and a plurality of X-shaped parts that raise and lower the door window (13) via the support rail (21). The link member (24) of the link mechanism (22) is pivotally connected to the phase hx.
) and a drive unit (2) that rotates this link mechanism (22).
3) and one end of the link member (24) fixed to the door inner panel outside the area and forming the link mechanism (22) (
25) and a subchannel (30) slidably supporting the subchannel (30).

The subchannel (30) has a groove-shaped cross section.

The door window (13) is formed into an asymmetrical shape bent in a substantially S-shape so that the door window (13) can be raised and lowered along a predetermined movement trajectory, and a mounting stud bolt (32) is attached to the rear surface (31).
(33) is erected.

Conventionally, such a subchannel (30) was connected to the door body (
11) When installing on the door inner panel, the door inner panel has mounting holes corresponding to the stud poles (32) and (33) for mounting the subchannel (30). Stud bolt (32),
(33) was commonly inserted and fastened with a nut.

However, with such a structure of conventional door window regulators, even if the front and back direction of the subchannel (30) is reversed, the mounting stud hole is still attached to the mounting hole (3).
Since inserting 2) and (33) is a serious matter, there is a risk of incorrectly assembling them, and if they are incorrectly assembled, the door window (13) will move on a completely different trajectory than the one set, even though it will be assembled. Since the door window (13) and the door body (11) may interfere with each other, the door window (13) may
3) is damaged or the door window regulator (
There was a problem that 2o) could be damaged.

``Purpose of the Invention'' The present invention has been made by focusing on such conventional problems, and prevents incorrect assembly of the subchannel and prevents problems such as interference between the door window and the door body. It is an object of the present invention to provide a mounting structure for a door window regulator as described above.

"Structure J of the Invention In order to achieve such an object, the present invention provides a door window support rail attached to the lower edge of the door window, and an A structure consisting of a link mechanism consisting of a link member that has arrived, a drive unit that rotates the link mechanism, and a subchannel that is fixed to the door inner panel and slidably supports one end of the link member of the link mechanism. In the above, at least one of the back surface of the sub-channel or the door inner panel is provided with a protrusion to prevent incorrect installation, which interferes with other forces when the direction of attachment of the sub-channel to the door inner panel is opposite to the normal direction. The unique door window regulator mounting structure prevents the subchannel from interfering with the door inner panel due to the protrusion that prevents incorrect installation even if the subchannel is accidentally reversed in the front and rear direction and you try to attach it to the door inner panel. It was made so that no one could visit the group.

"Example" Hereinafter, one embodiment of the present invention will be described based on the drawings.

Note that similar parts in the conventional example and each embodiment are given the same reference numerals, and redundant explanation will be omitted.

Figures 6 and 7 show a first embodiment of the present invention, in which a stud bolt (3°2) for mounting the subchannel (30), a back surface ( The door inner panel (40) has mounting holes (34) at positions corresponding to the stud holes (32) and (33) in the door inner panel (40). 41).

(42) and subchannel (30)
When installed in the IF normal direction, the subchannel (
30) A cut-out hole (43) is bored at the position corresponding to the cut-out hole 34) on the back, and the mounting stud poles (32) and (33') are inserted into the mounting hole (43). 41),
(42), cut and insert 34) into the insertion hole (43), and insert the extra issue stud bolt (32), (
33) and Natsuto (44).

(44) are screwed together and fastened and fixed.

In the door window regulator mounting structure having the above configuration, in order to install the subchannel (30), first attach the mounting stud bolts (32) and (33) installed on the back of the subchannel (30) to the door inner panel ( 40) into the mounting holes (41) and (42).

If the mounting direction of the sub-channel (30) is opposite to the normal direction, in other words, if the sub-channel (32) is
), when inserting the bolt (33) into the J hole (41), it will shift from the cutting hole (34) or the insertion hole (43) and interfere with the panel of the door inner panel (40). Unable to keep channel (30) in a stable position,
I can only add ζ1 to group A. If the mounting direction is correct, the screw 34) will fit into the insertion hole (43),
You can get into a stable position and that's it. (44)
) and (44) respectively for several phrases (32),
(33) and tighten it, the sub channel (
30) can be fixed to the door inner panel (40).

FIG. 8 shows a modification of the first embodiment.
Instead of 4), an L-shaped bracket (34a) may be fixed to the back (31) of the subchannel (30).
I'm forgetting that.

FIG. 9 shows a second embodiment, in which subchannels (3
0) on the bottom surface (35) of the groove (36).

(3?) is fixed, and one end (25) of the link member (24) of the link mechanism (22) is slidably engaged with the groove of the subchannel (30) via the roller (25a). and the side wall (38) of the subchannel (30)
(38) has a cutout (39) for inserting the roller (25a) into the groove, and the back (31) has a cutout (34) as a projection to prevent incorrect numbers. 6 and the door inner panel (40) has fastening bolts (45), (45) insertion holes (4B), (47).
is drilled, and when the subchannel (30) is installed in the regular direction as in the first embodiment, an insertion hole (43) is drilled at the cut-and-raised position 34) or a corresponding position. The insertion hole (47) is a long hole that allows the attitude of the subchannel (30) to be adjusted.

In the door window regulator mounting structure according to this embodiment, the subchannel (30) is connected to the door inner panel (
40), first install the subchannel (30).
34) into the insertion hole (43) of the door inner panel (40). If the sub-channel (3o) is installed in the opposite direction, the weld nuts (3B) and (37) will not align with the insertion holes (4B) and (4?), so the fastening bolts (45) and (45) ) to Weldnand (
3B).

(37) could not be screwed together, and the door inner panel (
40) cannot be fixed.

If the sub-channel (30) is in the normal installation direction, the wells 1ζsu7 +- (38) and (37) will fit into the insertion holes (4B) and (4?) of the door inner panel (40), so the insertion holes (4B) Concluded to (47) Pol l- (45), (
45) and weldna 71 (38), (37)
The subchannel (30) can be fixed by screwing and fastening to the subchannel (30).

At the time of this screwing, it is possible to cut and pull the bolt 34) into the insertion hole (43) and temporarily tighten it, making the work easier. When doing so, it has the advantage of being able to prevent the sub-cell Yannel (30) from rotating together.

10 and 11 show a third embodiment, in which the first embodiment and the back surface of the rfil-like subchannel (3o)
31) Attach to [1 stud bolt (32), (33)
However, the distance between the mounting stand bolt (32) and one end of the sub-channel (30) (30a), which is provided with a cut-up stand 34), is Pol I (33) and sub channel (3o
) is arranged asymmetrically so as to be smaller than the distance from the other end (30b), and the 1N inner panel (40) has one end (
30a) as a bead (4) as a 1F protrusion to prevent incorrect installation.
8) protrudes, as well as stud pole l-(3) for extra issue.
Several holes (41) and (42) of 2) and (33) are bored, and the attachment hole (42) is formed into a long hole that allows the attitude of the subchannel (30) to be adjusted.

In this embodiment, to install the subchannel (3θ), insert the mounting stud poles (32) and (33) into the mounting holes (41) and (42). Subchannel (
If 3o) is opposite to the normal installation direction, the other end (3ob)
Since the side back surface (31) rides on the bead' (48), it is impossible to maintain a stable posture and it is impossible to take it off.

If the sub-channel (30) is in the normal installation direction, one end (3Oa) is located close to the bead (48) and will not interfere, so the posture of the sub-channel (3o) will be stable and it will be easy to install. Statpol) (32), (33
) can be screwed into the mounting holes (41) and (42) to fix the subchannel (30). Although each embodiment is explained using a rear door as an example, it goes without saying that the same mounting structure can be applied to a front door as well.

"Effects of the Invention" According to the 1/1 structure of the door window regulator according to the present invention, the erroneous number prevention 1F protrusion is provided on either the subchannel or the door inner panel, and the subchannel is installed in the correct direction. Incorrect installation prevention 11 if the installation direction is reversed.
- Since the protrusion and the subchannel or the door inner panel will not interfere with each other to stabilize the subchannel, the subchannel will always be installed in the correct position, completely preventing incorrect installation. , the door window regulator will no longer operate abnormally and cause interference or damage.
