Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the structure of a connecting portion between a window panel made of glass or resin and a regulator that moves it up and down.

Conventionally, as this type of connection structure, for example, the first
As shown in Figures 3 to 3, resin holders 2, 2 are fitted and adhered to the front and back of the lower part of a door window glass 1 serving as a window panel, and screw insertion holes 3 and embedded nuts 4 are pre-inserted in this holder 2. A locking hole 8 in the shape of a locking hole is opened in the guide channel 7 of the regulator 6 disposed inside the door, and the screw 5 is temporarily fixed by screwing the screw 5 therein in advance. After inserting the head 5a of the screw 5 into the large diameter portion 8a of the locking hole 8, the shaft portion 5b of the screw 5 is appropriately slid and locked into the small diameter portion 8b of the locking hole 8, and then the screw 5 is inserted. Tighten completely and attach the above holder 2.
There is one in which the guide channel 7 and the guide channel 7 are brought into contact with each other and connected. Note that the small diameter portion 8b of the locking hole 8
is formed to have a larger diameter than the shaft portion 5b of the screw 5,
The positions of the holder 2 and the guide channel 7 can be adjusted in the vertical direction.
In addition, in FIG. 1, 9 and 10 are the main arm and sub-arm of the regulator 6, 11 is the handle shaft,
12 is a gear that meshes with the gear teeth of the handle shaft 11;
13 is a spring (for example, Utsukai 52-
(See Publication No. 28813).

However, in such a conventional connection structure, although the holder 2 and the guide channel 7 are in pressure contact with each other, their contact surfaces 2a,
Since both 7a are smooth surfaces, the fastening of the screw 5 may loosen due to, for example, vibrations when the vehicle is running or repeated loads applied to the guide channel 7 when operating the regulator 6, causing the holder 2 and the guide channel 7 to become loose. Not only will the connecting portion rattle and create a gap where abnormal noise is generated, but it will also become difficult to maintain the posture of the door window glass 1 in an appropriate position.

Incidentally, such a problem also occurs in a type in which a mounting part is formed at the lower part of a resin-made window panel, and this mounting part is brought into direct contact with the guide channel 7 and fixed with the screw 5.

The present invention has been made based on the above-mentioned viewpoints, and its purpose is to control the loosening of the screws that fasten the mounting portion of the window panel and the guide channel, and thereby prevent the loosening of the screws. To provide a connection structure between a window panel and a regulator, which prevents the accompanying wobbling of both members and allows the window panel to always be kept in a proper position.

The gist of the present invention is that an engagement recess is formed on one contact surface of the mounting portion of the window panel and the guide channel, and that the other contact surface is engaged with the engagement recess. This is a connection structure between a window panel and a guide channel in which loosening of screws is restricted by forming an engaging convex portion to prevent relative movement of the guide channel with respect to a mounting portion of the window panel.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

In the embodiment shown in FIGS. 4 to 8, the basic structure of the resin holder 2 that holds the door window glass 1 is almost the same as the conventional one, but unlike the conventional one, the holder 2 is connected to the guide channel 7. As shown in FIGS. 4 and 5, the contact surface 2a has a plurality of groove-shaped engagement recesses 20 extending linearly in the width direction, that is, the horizontal direction, of the holder 2 in a row in the vertical direction of the holder 2. This engaging recess 20 is provided in the holder 2.
It can be integrally molded with a mold during molding.

Further, the guide channel 7 of the regulator 6 is provided with a substantially cross-shaped engagement hole 21, as shown in FIGS. 4 and 6. That is, this locking hole 21 has a large diameter portion 2 through which the head 5a of the screw 5 is inserted.
1a, and small diameter portions 21b that extend in the longitudinal direction of the guide channel 7 and are connected to both sides of the large diameter portion 21a and have a larger diameter than the shaft portion 5b of the screw 5 and a smaller diameter than the large diameter portion 21a. The upper and lower edges of the large diameter portion 21a and the small diameter portion 21b are formed in a straight line along the longitudinal direction of the guide channel 7, and the upper and lower edges of the large diameter portion 21a and the small diameter portion 21b are engaged with each other. A convex portion 22 projects linearly in the horizontal direction toward the holder 2 and is adapted to engage with the engagement recess 20 . And again,
The engagement protrusion 22 can be integrally formed by burring when the locking hole 21 is opened.

Therefore, in this embodiment, when the door window glass 1 is connected to the regulator 6, the screw 5 is temporarily fastened to the holder 2 side as in the conventional case, and the locking hole 21 of the guide channel 7 is
After inserting the head 5a of the screw 5 into the large diameter part 21a of the locking hole 21, insert the shaft part 5 of the screw 5 into the small diameter part 21b of the locking hole 21.
The relative position between the holder 2 and the guide channel 7 may be adjusted by appropriately sliding the screw 5, and the screw 5 may be fully tightened. At this time, the contact surface 7a of the guide channel 7 comes into contact with the contact surface 2a of the holder 2, and in this state, the engagement convex portion 22 of the guide channel 7 as shown in FIGS. 7 and 8 As shown, it is in a state where it is fitted into the engagement recess 20 of the holder 2. Therefore, the relative positions of the guide channel 7 and the holder 2 are mutually restricted.
The guide channel 7 and the holder 2 will not move relative to each other due to vibrations when the vehicle is running or repeated loads applied to the guide channel 6 when the regulator 6 is operated, and there is no concern that the screw 5 will loosen. do not have.

Furthermore, in this embodiment, a plurality of the engagement recesses 20 are arranged in parallel in the vertical direction on the contact surface 2a of the holder 2, so that, for example, it is possible to maintain the posture of the door window glass 1 in an appropriate position. Even if the holder 2 and the guide channel 7 are adjusted in position in the vertical direction, the engagement protrusion 22 on the guide channel 7 side will always engage with the engagement recess 20 at the appropriate position, and the guide channel 7 and holder 2
The relative position with respect to is always regulated.

Furthermore, in this embodiment, the engagement recess 20
Since the engaging convex portion 22 is formed to extend linearly, it is possible to secure a wider engagement area between the two, thereby reliably regulating the relative movement between the guide channel 7 and the holder 2. can do.

In the above embodiment, the engagement recess 20 is formed on the holder 2 side, and the engagement protrusion 22 is formed on the guide channel 7 side, but the positional relationship between the two may be reversed. Moreover, the engagement recess 20 and the engagement protrusion 22
The design may be changed as appropriate regarding the shape, number, molding locations, etc. Further, the locking holes 21 of the guide channel 7 are not limited to those shown in the above embodiments, and the present invention can be applied to holes having an appropriate shape. Furthermore, in a resin window panel, without using the holder 2,
Of course, the present invention can also be applied to a structure in which a mounting portion is formed on a window panel and the connecting portion between this mounting portion and the guide channel 7 is formed.

As described above, according to the structure of the connecting portion between the window panel and the regulator according to the present invention, an engaging recess is formed in the contact surface of one of the mounting portion of the window panel and the guide channel of the regulator, and An engagement protrusion that engages with the engagement recess is formed on the other contact surface, and both are fixed with screws, so that vibrations when the vehicle is running and reversal loads applied to the guide channel when operating the regulator can prevent There is no longer any relative movement between the mounting portion of the window panel and the guide channel, and there is therefore no possibility that the screws may become loosely fastened. Therefore, rattling between the window panel mounting part and the guide channel is effectively prevented, which makes it possible to suppress the occurrence of abnormal noise and maintain the window panel in an appropriate position. .
