BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive connection portion of a roof rail for a vehicle, which can perform a good treatment of an adhesive for coating and filling, for example, in a fitting connection between a male and a female portion of a roof rail member for a vehicle.

[0002]

2. Description of the Related Art In a recent wagon vehicle or the like, for example, as shown in FIG. 7, there is a fashion rail or the like in which a roof rail portion 2 is attached to a roof of a vehicle 1.
As the structure of the roof rail portion 2, there are various structures. For example, as shown in the figure, a roof rail member 21 of a long rod-like pipe and leg-shaped roof rail members 22, 22 for supporting the roof rail member at the left and right are also proposed. Have been.

When assembling the roof rail section 2, for example, as shown in FIG. 8, first, an adhesive 3 is poured into a pipe inner surface 21a at an end of a roof rail member 21, and the pipe inner surface 21a shown in FIG. As described above, a method is employed in which the protruding male portion 22a of the roof rail member 22 is fitted and adhesively connected.

[0004]

[Problems to be Solved by the Invention] However, in the case of a connection portion by such an insertion method, a sufficient bonding effect cannot be obtained, or a clean bonding process cannot be performed, and furthermore, the amount of adhesive used is There were problems such as an increase. In addition, such a bonding method has a problem that high reliability cannot be obtained because the state of bonding cannot be visually observed from the outside. That is, FIG.
When the male portion 22a is inserted into the pipe inner surface 21a as shown in FIG.
There is a problem that a part of the poured adhesive 3 is pushed out to the inner part of the pipe, and the adhesive 3 does not sufficiently turn into the gap between the two. The extruded adhesive 3a does not contribute to the adhesion at all, and the larger the amount, the smaller the amount of the adhesive that goes into the gap between the two, the stronger the adhesive 3 used. The result is that it cannot be obtained.

However, if the gap between the pipe inner surface 21a and the male portion 22a is set wider (loose), a large amount of the adhesive 3 is required, which is not only uneconomical, but also uneconomical.
A part of the adhesive 3 leaks to the outside and becomes visible, causing a problem that a clean bonding process cannot be performed. Further, if the gap is wide, before the adhesive 3 is cured, there is also a problem that the two members 21 and 22 are apt to rattle, so that accurate bonding cannot be expected.

The present invention has been made in view of such a conventional situation, and has a female roof rail provided with means for assisting the adhesive around female holes and male portions of both roof rail members to be bonded and connected to each other. No adhesive connection is provided.

[0007]

The adhesive connecting portion of the roof rail for a vehicle according to the present invention has a plurality of grooves for introducing an adhesive in a longitudinal inner surface of the female hole 121a of at least one roof rail member 121. And the outer edge of the groove
In addition to forming an enlarged diameter near the portion , or providing a plurality of grooves for introducing the adhesive agent which are appropriately spaced apart from the base side step portion on the longitudinal outer periphery of the male portion 122a of the other roof rail member 122, and , Formed near the leading edge of the groove with an enlarged diameter
On the other hand, an adhesive is applied to the tip of the inner surface of the female hole 121a or to the tip of the male part 122a, and the male part 122a of the other roof rail member 122 is fitted into the female hole 121a while being inserted. Guiding the applied adhesive into the groove for introducing the adhesive, and firmly bonding the inner surface of the female hole 121a and the male portion 122a,
The end face of the female hole 121a is connected to the other roof rail member 12
A proximal end side stepped portion of the second male portion 122a lies in the so as to abut.

[0008]

In the adhesive connection portion of the vehicle roof rail, the longitudinal inner surface of the female hole 121a of one roof rail member 121 or the other roof rail member 122
Since there are a plurality of grooves for introducing the adhesive which are appropriately spaced apart from the proximal end of the male portion 122a in the longitudinal outer periphery of the male portion 122a, the adhesive is introduced into this groove when fitting, and as a result, The adhesive satisfactorily and properly turns into the gap between the fitting surfaces. Thus, a sufficiently strong connection can be obtained with a relatively small amount of adhesive. In addition, since the gap does not need to be set particularly wide, a highly accurate connection can be obtained. Further, the adhesive is applied in advance from the inner end of the female hole of the roof rail member or to the male part of the roof rail member, and is pushed by the male part of one roof rail member at the time of fitting, so that the adhesive leaks out. There is no fear. Especially female hole 1 of roof rail member 121
The groove for introducing the adhesive 21a is formed with an enlarged diameter near the outer edge, or the male portion 1 of the other roof rail member 122 is formed.
Since the diameter of the groove for introducing the adhesive 22a near the leading edge is increased, the adhesive can rotate more favorably and appropriately.

[0009]

FIG. 1 shows an embodiment of an adhesive connection portion of a vehicle roof rail according to the present invention. In the figure, 121 is a roof rail member of a long rod-shaped pipe (a member other than a pipe is also possible), and 122 is a leg-shaped roof rail member (regardless of a pipe or a solid body) supporting the same. The protruding male portion 122a of the leg-shaped roof rail member 122 is provided with a plurality of adhesive introduction grooves 104a in the axial direction of the outer periphery thereof as shown in FIG.

Therefore, these two members 121, 12
At the time of connection, first, an appropriate amount of adhesive 103 is poured into a pipe inner surface (female hole) 121a which is an end of the rod-shaped pipe roof rail member 121, and then the leg-shaped roof rail member is inserted into the pipe inner surface 121a. The male part 122a of the base 122 is inserted and fitted. At this time, if necessary, the adhesive 103 is applied in advance to the tip of the male portion 122a. Although the adhesive 103 in the pipe is partially pushed out by the insertion of the male portion 122a, the adhesive introduction groove 104 of the male portion 122a is relatively smoothly.
a, and as a result, the two members 121, 122
It will be filled evenly between them. Further, since the adhesive 103 is pushed out further into the pipe inner surface 121a by inserting the male portion 122a, it hardly leaks outside. Then, in this state, the adhesive 103
When the is cured, the adhesive connection portion of the vehicle roof rail, which is the object of the present invention, is obtained.

In the adhesive connection portion of the vehicle roof rail, the adhesive 103 is relatively smoothly formed around the adhesive 104 by the groove 104a, so that a strong adhesion can be obtained with a relatively small amount of the adhesive 103. Further, since the adhesive 103 is filled widely along the formation range of the groove 104a, a highly stable connection can be obtained over a wide range. Of course, since the gap between the two members 121 and 122 is not specially widened for the filling of the adhesive 103, the connection with high precision can be obtained without rattling. Further, since it is not necessary to apply an unnecessarily large amount in the filling of the adhesive 103, there is no inadvertent leakage of the adhesive, and a clean connection can be obtained.

In the above embodiment, the male member 122a of the roof rail member 122 has a groove 104a for introducing an adhesive.
However, the present invention is not limited to this. For example, as shown in FIG. 3, a similar groove 105a for introducing an adhesive is provided in the pipe inner surface 121a of the roof rail member 121, and the male portion 122a of the roof rail member 122 is made a normal male member without a groove. The members 121 and 122 have respective grooves 104a and 105
Can be provided and bonded.

Further, the form of the groove is not particularly limited. For example, as shown in FIGS.
In the male portion 122a of the roof rail member 122, grooves 104b to 104d having various shapes can be formed. That is, since the adhesive 103 is filled in along the groove shape, it can be appropriately changed according to strength requirements and other conditions. Of course, the same applies to the groove 105a provided on the pipe inner surface 121a side. The groove may have any structure as long as the adhesive 103 flows therein, and includes a number of concave and convex grooves such as a knurled finish.

In the above embodiment, the roof rail member 121 is made of a pipe material. However, the present invention is not limited to this. In the case of a solid body, a blind hole may be provided at the end to form a female hole.

[0015]

As is clear from the above description, according to the adhesive connection portion of the vehicle roof rail according to the present invention, the adhesive is provided in the longitudinal direction of the female holes and the male portions of both roof rail members to be adhesively connected to each other. As a means to help around, along with providing a plurality of grooves for introducing the adhesive, since the groove on the male part is appropriately separated from the base side step, it is stopped.
Smooth inflow of the adhesive and stopping at an appropriate position become possible, and a strong and leak-free adhesive can be obtained with a relatively small amount of adhesive. That is, highly reliable adhesion can be obtained. Further, since the adhesive can flow freely along the formation range of the groove, a highly stable connection can be obtained over a wide range. Also, the groove may be formed within a short range only in a portion inside the female hole of the vehicle roof rail and completely outside the male portion of the roof rail member, which is completely hidden from the outside at the time of assembling, without causing a significant rise in cost. Also,
Since the gap between the two roof rail members is not specially widened for the filling of the adhesive, the connection can be obtained with high precision without rattling. Also, since the adhesive is applied near the tip of the female hole of the roof rail member or near the tip of the male part, there is no possibility that the adhesive leaks out of the female hole, and a beautifully finished connection is obtained. Can be In particular, the diameter of the female hole near the outer edge of the adhesive introduction groove is increased or
Alternatively, since the diameter of the male adhesive groove near the tip edge of the groove for introducing the adhesive is enlarged , the adhesive can be turned more properly and appropriately, so that a cleaner connection without adhesive leakage can be obtained. . Furthermore, at the time of filling the adhesive, it is not necessary to apply an unnecessarily large amount of adhesive by the action of the groove for introducing the adhesive. A connection with a beautiful finish can be obtained.
