Description

Specification

Automotive window structure

The present invention relates to an automotive window structure. Background art

As shown in FIG. 5 and FIG. 6, a transparent plate 71 with a molding used for a front window of an automobile 70 has a substantially trapezoidal shape (in plan view) and a glass plate 72 curved in a two-dimensional or three-dimensional direction. A molding 80 made of resin is provided along the upper side 73 and both sides 74, 74 of the glass plate 72. The transparent plate 71 with a molding is fitted into a window opening 75 formed in the body panel 70A.

The molding 80 may be called a frame, a gasket, or the like, but is referred to as “molding” in this specification. The upper side 73 of the glass plate 72 refers to the side along the roof 76 of the vehicle 70, and the side of the glass plate 72 refers to the side along the pillar 77, etc. of the vehicle 70. The upper side mounting portion 81 and the side side mounting portion 82 having a substantially U-shaped cross section that continuously engages the upper side 73 and the side side 74 of the plate 72, and the surface of the glass plate 72 from the upper side mounting portion 81 and the side side mounting portion 82 And a lip portion 83 extending outward in the direction. Then, the transparent plate 71 with the molding is applied along the back-up material 85 while interposing the back-up material 85 between the back surface (inside of the vehicle) 72 A of the glass plate 72 and the mounting flange 76 of the window opening 75. The appropriate adhesive 86 is fitted into the window opening 75 and fixed. At this time, between the upper side 73 and both sides 74 of the glass plate 72 and the opening side wall 75A, the lip portion 83 is elastically deformed and adheres to the opening side wall 75A, so that waterproofness is obtained.

The transparent plate 71 with molding is a mold cavity with glass plate 72 By injecting a molten resin into the space, the glass plate 72 can be manufactured by an encapsulation method or the like in which a molding 80 is formed along the upper side 73 and both sides 74, 74 of the glass plate 72.

FIG. 8 shows another conventional example (described in JP-A-63-240424). In this example, the periphery of the glass plate 72 is held by a holding member 91 having a substantially U-shaped cross section. Insert the tip of the bolt 92 protruding from the lower surface of the holding member 91 (the surface in contact with the back surface of the glass plate 72) through the mounting flange 76 of the window opening 75, and tighten the nut 93 to the tip of the penetrated port 92. As a result, the glass plate 72 is attached to the body panel 70A. The holding member 91 is covered with a molding 94. By making the lip 95 formed in the molding 94 adhere to the surface of the window opening 75, waterproofness is ensured. An adhesive 96 is injected into a gap between the molding 94 and the opening side wall 75A.

In recent years, mainly due to the demand for recycling of industrial products, it has been demanded that the glass plate 72 for automobiles can be easily removed from the pod panel 70A. However, in the conventional example shown in FIG. 7, since the transparent plate 71 with the molding was attached to the body panel 70A by bonding, the glass plate could not be easily removed. In the conventional example shown in FIG. 8, since the holding member 91 for supporting the glass plate 72 is fixed to the window opening 75 with the bolt 92 and the nut 93, the attachment / detachment of the holding member 91 is very complicated.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings. In the embodiments described below, the same members and the like as those already described in FIGS. 6 and 7 are denoted by the same reference numerals in the drawings to simplify or omit the description.

As shown in FIG. 1 and FIG. 2, a holding member 15 having a substantially U-shaped cross section for holding the glass plate 72 in the thickness direction is provided around the upper side 73 and the side side 74 of the glass plate 72. It is attached. Then, a molding 11 having a substantially U-shaped cross section is attached so as to cover the holding member 15. The glass plate 72 of this example is an example of a rear window of an automobile. Here, as shown in FIG. 2, a step portion 72D is provided on the peripheral side of the glass plate 72 on the front side (the upper side in the figure; the outside of the vehicle when attached to the vehicle body). By placing the holding member 15 and the molding 11 on the stepped portion 72D, the surface of the molding 11 is exactly flush with the surface 72B of the glass plate 72.

The holding member 15 is provided with an engagement pin 16 extending in a direction away from the rear surface 72A of the glass plate 72 (downward in the figure; in the vehicle when mounted on the vehicle body). The engagement pin 16 is provided in the window opening 75 and is substantially perpendicular to the extension direction of the engagement pin 16. Through the through-hole 76A of the mounting flange 76 that extends. At the tip of the engaging pin 16, a locking portion 17 for preventing the engaging pin 16 from being pulled out from the mounting flange 76 is provided. Here, the locking portion is formed integrally with the engaging pin 16, and the bottom surface thereof is formed in a substantially conical shape in contact with the mounting flange 76. In a plan view (a bottom view in the figure), the outer periphery of the locking portion 17 protrudes from the outer periphery of the engagement pin 16. The molding 11 extends from the upper side mounting portion 12 and the side side mounting portion 13 having a substantially U-shaped cross section, which are continuously engaged with the upper side 73 and the side side 74 of the glass plate 72, and extends from the mounting portions 12, 13. And a lip portion 14 that is in close contact with the opening side wall 75A.

Notches 18 are provided at predetermined positions of the upper side mounting portion 12 and the side side mounting portion 13 of the molding 11 to avoid interference with the engaging pins 16 as shown in FIG. With the holding member 15 attached first to the peripheral edge of the glass plate 72, the molding 11 can be fitted from the side later.

To attach the glass plate 72 to the window opening 75, the engaging pin 16 and the engaging portion 17 are used without using an adhesive. First, as shown in FIG. 2, a sealing material 19 made of butyl rubber is disposed on the outer peripheral side of the through hole 76A on the surface of the mounting flange 76. Next, the tip of the engaging pin 16 protruding from the lower surface of the holding member 15 is passed through a through hole 76A formed in the mounting flange 76. Then, the engaging portion 17 at the tip of the engaging pin 16 is pushed into the rear surface of the mounting flange 76. As a result, the engaging pin 16 is locked by the locking portion 17 and cannot be pulled out from the mounting flange 76, and the glass plate 72 is mounted on the window opening 75.

In this mounting state, the lip portion U adheres tightly to the opening side wall 75A while being elastically deformed, thereby ensuring waterproofness. Then, the sealing material 19 made of butyl rubber is compressed and elastically deformed between the rear surface of the molding 11 and the surface of the mounting flange 76, so that the sealing material 19 functions as a waterproof means to further enhance waterproofness. When the transparent plate with a molding having such a configuration is to be removed from the window opening 75, the engaging portion 17 at the tip of the engaging pin 16 is cut as shown in FIG. Then However, since the molding 11 is not fixed with an adhesive, the engagement pin 16 can be easily pulled out from the through hole 76A of the mounting flange 76 by lifting the glass plate 72. After that, the glass plate 72 with the molding 11 can be removed simply by lifting the glass plate 72 as it is. Thereafter, as shown in FIG. 4 (B), the holding member 15 and the molding 11 are removed from the glass plate 72, and only the glass plate 72 is put into the melting furnace.

In the above-described vehicle window structure, the engaging pin 16 is penetrated through the mounting flange 76 of the window opening 75, and the engaging pin 16 is locked to the mounting flange 76 by the locking portion 17. The glass plate 72 can be easily attached to the window opening 75. Then, the glass plate 72 with the molding 11 can be easily removed from the window opening 75 by cutting off the locking portion 17 from the engaging pin 16. Further, by removing the holding member 15 from the glass plate 72, the molding 11 and other members constituting the frame can be removed from the glass plate 72. Therefore, the work of removing the glass plate 72 is significantly simplified, and the recyclability is extremely good.

Further, in this automotive window structure, the lip portion 14 integrally formed with the molding 11 adheres tightly to the opening side wall 75A while elastically deforming to ensure waterproofness, and furthermore, the sealing material 19 elastically deforms. While molding, it adheres tightly to the back surface of the molding 11 and the surface of the mounting flange 76 to enhance waterproofness. Therefore, it has a high level of waterproofness even though no adhesive is used.

Note that the present invention is not limited to the above-described embodiment, and appropriate modifications and improvements can be made.

For example, instead of the seal material 19 made of butyl rubber, a second lip portion that is in close contact with the surface of the mounting flange 76 may project from the molding 11. In this way, the complexity of the work of attaching the seal material 19 can be reduced.

Further, in the above embodiment, the step portion 72D is provided on the front surface side of the glass plate 72. However, a step portion can be provided on the back surface side of the glass plate 72. When using a transparent plate for the front window, the transparent plate must be made of laminated glass. There are many. In this case, the step can be provided by making the size of one glass plate of the laminated glass smaller than the size of the other glass plate. The setting of these steps is optional, but it is preferable to set the steps in that the molding surface and the transparent plate surface can be flush with each other when the molding is provided.

Various forms can also be exemplified as the form in which the mounting pin member is provided on the transparent plate. For example, the mounting pin member can be connected to the transparent plate without using a holding member for holding the periphery of the transparent plate. Also, instead of being directly joined to the transparent plate, it may be provided so that a part of the mounting pin member is embedded in a molding integrated with the periphery of the transparent plate. In view of the high holding force on the transparent plate, it is preferable to hold the peripheral edge of the transparent plate with the holding member.

Molding settings are also optional. In the case where the molding is provided on the transparent plate, and when a sealing means (sealant) different from the molding is provided, the sealant is provided between the transparent plate and the mounting flange via the molding. It is preferable that the molding is provided on the periphery of the transparent plate from the viewpoint of improving the watertightness and the holding property between the mounting pin member and the transparent plate. The molding is preferably made of a thermoplastic resin such as polyvinyl chloride, styrene-based elastomer, or olefin-based elastomer.

Further, the materials, shapes, dimensions, shapes, numbers, and the like of the automobile, the transparent plate, the upper side, the side, the molding, the upper side mounting portion, the side side mounting portion, the engaging pin, the locking portion, and the like exemplified in the above embodiment. The location, the presence or absence of coloring, and the like are arbitrary as long as the invention can be achieved. Industrial applicability

As described above, according to the present invention, the transparent plate can be removed from the window opening simply by removing the locking portion at the tip of the engaging pin, so that the removing operation can be performed easily and recycling can be achieved. It will be easier. Also, after removing the holding member from the transparent plate, the transparent plate can be put into the melting furnace as it is. No impurities are mixed.

In the present invention, by using a molding as a sealing means disposed on the outer peripheral side of the engagement pin, when the window opening is sealed with a flexible portion connected to the molding, it is possible to improve the appearance and the waterproofness. .
