Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a window molding for an automobile.
[0002]
[Prior art]
Conventionally, in an automobile, as shown in FIGS. 5 and 6, an automobile window molding 60 is mounted in a gap S between an edge of a window glass G and a window frame F of a vehicle body. Covering is being done. Reference numeral A denotes an adhesive for fixing the edge of the window glass G to the window frame F.
[0003]
The window molding 60 is made of a deformable material such as plastic or rubber. A window glass insertion groove 61 is provided on the window glass G side, and the window molding F is formed on the opposite side of the window glass insertion groove 61 with the window frame F. A fin piece (also referred to as a lip) 62 for closing the gap is formed.
[0004]
In the conventional window molding 60 shown in FIG. 6, a hollow leg 63 having a substantially hollow rectangular tube shape is formed on the back side, and the bottom of the hollow leg 63 is bonded to the bottom F1 of the window frame F with an adhesive 70. (See Patent Document 1).
[0005]
[Patent Document 1]
JP-A-10-16550 (FIGS. 1 and 2)
[0006]
[Problems to be solved by the invention]
The window glass G attached to the window frame F tends to vary in distance d from the window frame bottom surface F1 due to variations in the operation of attaching the window glass and dimensional errors of the window frame F. Therefore, in the wind molding 60, the variation in the distance d between the edge of the window glass G and the window frame bottom surface F1 must be absorbed by the elastic deformation of the hollow leg 63. Since the entire circumference of the leg portion 63 is surrounded by the wall surface 64, it is difficult to say that the leg portion 63 is easily deformed, and it is difficult to absorb the variation in the distance d. As a result, the wind molding 60 may not be correctly fixed to the window glass G and the window frame F, and may be partially raised or inclined.
[0007]
Furthermore, since the wind molding 60 is located on the outer surface of the vehicle body, the temperature changes greatly due to the presence or absence of direct sunlight, seasonal changes, and the like, causing expansion and contraction due to the temperature changes. Therefore, the wind molding 60 needs to be fixed to the window frame F so as to be hardly affected by expansion and contraction caused by the temperature change.
[0008]
However, in the window molding 60 having the hollow leg 63, the fixing to the window frame F is performed only by bonding the bottom of the hollow leg 63 to the window frame bottom surface F1. Therefore, when the expansion and contraction of the wind molding 60 is repeated for a long time and stress is repeatedly applied between the bottom of the hollow leg 63 and the adhesive 70, the hollow leg 63 and the window frame bottom surface F1 There is a possibility that the wind molding 60 may be partially lifted or tilted from the window frame 70 due to loss of adhesion of the window molding.
[0009]
[Problems to be solved by the invention]
The present invention has been made in view of the above points, and can reliably attach a wind molding even if there is variation in the height of a window glass attached to a window frame, and easily and reliably without lifting or tilting. This is to provide a wind mall that can be fixed.
[0010]
[Means for Solving the Problems]
The invention according to claim 1 is an automotive wind molding mounted in a gap between an edge of a window glass of an automobile and a window frame of a vehicle body, wherein the wind molding is expanded behind the wind molding in a width direction of the wind molding. It is characterized in that two elastic leg pieces are formed.
[0011]
According to a second aspect of the present invention, in the first aspect, the wind molding has a main body having a window glass insertion groove formed on a side thereof, and the two elastic leg pieces are formed on the back side of the main body. The space between the back surface of the main body portion on the side of the window glass insertion groove and the elastic leg piece on the side of the window glass insertion groove constitutes a concave portion for window glass adhesive penetration.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a cross-sectional view showing an attached state of a wind molding according to a first embodiment of the present invention, FIG. 2 is a perspective view of a corner portion in the wind molding of FIG. 1, and FIG. FIG. 4 is a cross-sectional view showing an attached state of the wind molding, and FIG. 4 is a perspective view of a corner portion in the wind molding of FIG.
[0013]
A window molding 10A of the first embodiment shown in FIGS. 1 and 2 is mounted in a gap S between an edge of a window glass G and a window frame F of a vehicle body, and has a main body 11 made of synthetic resin or rubber. And two elastic leg pieces 21 and 25.
[0014]
The main body 11 has a window glass insertion groove 12 formed on the side of the window glass G, and a fin 13 (also referred to as a lip) formed on the opposite side. The edge of the window glass G is inserted into the window glass insertion groove 12. In addition, the fin piece 13 contacts the peripheral wall F2 of the window frame F at the tip, and covers the gap between the edge of the window glass G and the peripheral wall F2 of the window frame F. In addition, a core material such as a metal wire may be appropriately embedded in the main body portion 11 to reduce the coefficient of linear expansion of the wind molding 10A and suppress expansion and contraction of the wind molding 10A due to a temperature change.
[0015]
The two elastic leg pieces 21 and 25 are formed by elastic pieces whose tip sides are expanded in the shape of an “eight” in the width direction W of the wind molding 10. The elastic leg pieces 21 and 25 are arranged such that when the window molding 10A is mounted in the gap S between the edge of the window molding 10A and the window frame F, the ends of the elastic leg pieces 21 and 25 are in contact with the window frame bottom surface F1. Then, they are elastically deformed according to the distance d between the window glass G and the window frame bottom surface F1. Therefore, even if the mounting height of the window glass G varies, the window molding 10A can be positioned at a position corresponding to the height of the window G without fear of inclination or the like.
[0016]
Further, when the window molding 10A is bent along the corner portion (reference numeral G1 in FIG. 5) of the window glass G, it cannot freely expand and contract on the inner and outer peripheral sides of the molding. At least one of 21 and 25 is slackened (remaining), and the slack tends to hinder the bending of the wind molding 10A or easily deform the wind molding 10A. In order to solve this problem, at least one of the two elastic leg pieces 21 and 25, in particular, the wind glass G is provided at the corner C of the wind molding 10A which is bent along the corner of the wind glass G. Forming one or more slits 22 made of split lines or cutouts in the elastic leg pieces 21 that are inside when bent along the corners of G, that is, the elastic leg pieces 21 on the side of the window glass insertion groove 12, It is preferable to prevent the occurrence of loosening during the bending.
[0017]
Further, the elastic leg piece 21 on the side of the window glass insertion groove 12 is formed at a position where its base 21a is recessed from the tip end 16 of the main body back surface 15 on the side of the window glass insertion groove 12. A recess 17 for the adhesive intrusion of the window glass is formed between the main body rear surface 15 on the side of the window glass insertion groove 12 and the elastic leg piece 21 on the side of the window glass insertion groove 12. An adhesive A provided between the edge of the window glass G and the bottom surface F1 of the window frame F to fix the window glass G to the window frame F is provided in the adhesive recess 17 of the window glass. The part enters and hardens. The adhesive A, which has entered the adhesive indentation recess 17 of the window glass and has hardened, exerts an anchoring effect between the back surface 15 of the main body 11 and the elastic leg piece 21 to move the window molding 10A to the window frame F. To be fixed. Moreover, the anchor effect is hardly affected even if the adhesiveness of the adhesive A is reduced, and is hardly affected even if the wind molding 10A expands and contracts in the length direction. The window molding 10A can be accurately fixed to the window frame F. Further, the elastic leg piece 21 on the side of the window glass insertion groove 12 also functions as a dam for preventing the free flow of the adhesive A, so that the adhesive A can stay at the edge of the window glass G. Thus, the adhesion between the window glass G and the window frame F can be ensured.
[0018]
The window molding 10B of the second embodiment shown in FIGS. 3 and 4 has an engagement projection 18 with the adhesive A of the window glass formed on the tip 16 side of the back surface 15 of the main body on the window glass insertion groove 12 side. This is different from the window molding 10A of the first embodiment in that the other points are the same as those of the window molding 10A of the first embodiment. In the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals as in the first embodiment. In the description of the first embodiment, the same parts as those of the second embodiment are replaced with the description of the wind mall 10B of the second embodiment by replacing the "wind mall 10A" with the "wind mall 10B". .
[0019]
In the window molding 10B of the second embodiment, when the adhesive A of the window glass penetrates into the adhesive indentation recess 17 of the window glass and is hardened to exert the anchor effect, the engagement protrusion Since the portion 18 is embedded and engaged in the adhesive A, the anchor effect of the adhesive A on the wind molding 10B is further enhanced. As a result, the window molding 10B can be more reliably and accurately fixed to the gap S between the edge of the window glass G and the window frame F over a long period of time.
[0020]
【The invention's effect】
As shown and described above, according to the first aspect of the invention, two elastic leg pieces are formed on the back side of the wind molding so as to expand in the width direction of the wind molding, and the window frame on which the window glass is mounted is formed. Since the elastic leg pieces are brought into contact with the bottom surface to be elastically deformed, the position of the wind molding can be made to correspond to the mounting height of the window glass. Moreover, since the elastic leg pieces are more easily elastically deformed than the hollow leg portions, it is possible to more easily cope with a variation in the mounting height of the window glass.
[0021]
Furthermore, according to the second aspect of the present invention, the gap between the back surface of the main body portion on the side of the window glass insertion groove and the elastic leg piece on the side of the window glass insertion groove constitutes an adhesive intrusion recess of the window glass. The adhesive that has penetrated into the adhesive intrusion recess and hardened exerts an anchor effect, so that the window molding can be securely fixed in the gap between the window glass and the window frame. In addition, since the anchor effect is not easily affected by the decrease in the adhesiveness of the adhesive or by the expansion and contraction of the window molding, the window molding is securely and accurately fixed to the gap between the window glass and the window frame for a long time. can do. Furthermore, since the wind molding is fixed by the anchor effect of the adhesive, it is not necessary to enhance the adhesion between the elastic leg and the adhesive, and a primer treatment for improving the adhesion to the elastic leg is not required. Can be omitted, which simplifies the operation and reduces the cost. Further, the elastic leg piece on the side of the window glass insertion groove also acts as a dam for preventing the free flow of the adhesive, so that the amount of the adhesive used can be suppressed, and the window glass can be securely bonded to the window frame. I do.
