For example, in Patent Document 1, in a clip that is bonded and bonded to a plate surface of a transparent plate via an adhesive, a frame-shaped recess is formed so as to surround the adhesive application surface of the clip, thereby A technique is described in which an adhesive overflowing from an adhesive application surface is stored in a concave portion.

JP 2010-014147 A

However, in the clip described in Patent Document 1, the adhesive strength between the clip and the adhesive applied to the adhesive application surface is weak, and the joint strength of the transparent plate to the window opening frame portion described above is weak. There was a problem.
The present invention has been devised to solve the above-described problems. That is, the problem to be solved by the present invention is to increase the bonding strength between the fastening material and the adhesive by using the overflowing adhesive in the fastening material bonded to the mounting member body through the adhesive. Thus, the bonding strength of the fastening material to the mounting member main body is improved.

In order to solve the above-described problems, the method of manufacturing the fastening material and the attachment member of the present invention takes the following means.
First, the first invention is a fastening material that enables the attachment member body to be attached to the attached member by being joined to the joining surface of the attachment member body.

And an attachment end that enables the main body to be attached to the member to be attached. The mounting end portion and the bonded end portion are filled with a raw material into a mold corresponding to the mounting end portion and the bonded end portion, and then the mold is moved from the mounting end portion toward the bonded end portion. Are integrally formed by opening the molds in the crossing direction. The bonded end portion overflows from the bonding surface bonded to the attachment surface of the mounting member body through the adhesive in the bonding process and between the bonding surface and the bonding surface in the bonding process. And a recessed portion into which the adhesive flows. This concave portion is formed in a shape that is open toward the mold opening direction of the mold, and when the adhesive flows into the concave portion and solidifies, it is adhered to the adhesive from the attachment end side. It is formed in a shape having a support surface that receives and supports the force applied in the direction toward the end side.
According to the first aspect of the present invention, the adhesive overflowing from between the affixing surface formed at the bonded end of the fastening material and the bonding surface of the attachment member main body is formed at the bonded end. Pour into the recess and solidify.

A bonding step of bonding with an adhesive. In the fastening material holding step, the bonded end portion of the fastening material is covered with a bonding jig from the outer peripheral side of the bonded end portion, and a gap is formed between the bonding jig and the outer surface of the bonded end portion. In the bonding process, the adhesive between the bonded surface of the bonded end and the bonding surface of the attachment member body overflows toward the outer peripheral side of the bonded end, and overflows toward the outer peripheral side. The bonded adhesive is poured into the concave portion of the bonded end portion through the gap while being clamped by the joining jig.
According to the third aspect of the present invention, the adhesive that overflows toward the outer peripheral side of the fastening material is squeezed by the joining jig, so that the concave portion having a shape opened toward the outer peripheral side of the bonded end portion in the fastening material. Adhesive can be poured into. Further, when the adhesive poured into the concave portion is solidified by the gap formed between the fastening material and the joining jig in the fastening material holding step, the solidified adhesive and the bonded end portion of the fastening material are The end portion to be bonded can be engaged and integrated as a state wrapped with the adhesive. Thereby, the joining strength of the said adhesive agent and a fastening material can be strengthened more, and the joining strength of the fastening material with respect to an attachment member main body can be improved.

Below, the structure of the fastening material 10 concerning one Embodiment of this invention is demonstrated using FIG. 1 thru | or FIG. In the following description, illustration and detailed description of an incidental configuration such as an adhesive that bonds and joins the opening frame portion 20A of the window 20 and the transparent plate 21 are omitted.
As shown in FIG. 1, the above-mentioned fastening material 10 is formed by bonding a polycarbonate transparent plate 21 to an opening frame portion 20A of an automobile window 20 by using an adhesive (not shown). It is a fastening material that is used to fix the transparent plate 21 to the opening frame portion 20A until it is solidified. Here, the opening frame 20A corresponds to the “attached member” in the present invention, and the transparent plate 21 corresponds to the “attaching member main body” in the present invention. In addition, the transparent plate 21 of this embodiment is shape | molded by the injection press molding of polycarbonate, and the coating layer 21B (refer FIG. 2) is provided in the plate | board surface of the one side.

As shown in FIGS. 2 and 5, the fastening material 10 is a hot melt resin (the solidified hot melt resin 14 in FIG. 2 and the molten hot melt resin 32A in FIG. 5, which corresponds to the “adhesive” in the present invention). The to-be-adhered end part 11 which can be joined to the joining surface 21A of the transparent plate 21 by adhesion via the attachment, and the attachment end part 10A that protrudes from the plate surface of the transparent plate 21 by the adhesion are provided. . Here, what joined the said fastening material 10 and the transparent plate 21 corresponds to the "attachment member" in this invention.
As shown in FIG. 2, the mounting end 10 </ b> A has a pair of locking claws 10 </ b> B that project radially outward from the tip of the mounting end 10 </ b> A and bend inward and outward 2 opposite to each other in the circumferential direction. It is formed at the location. Accordingly, as shown in FIG. 1, in the state where the fastening material 10 is joined to the transparent plate 21, the attachment end 10A is inserted into the locking hole 20B of the opening frame portion 20A described above, and the attachment end 10A. By locking the locking holes 20B with the locking claws 10B, the above-described transparent plate 21 can be attached to the opening frame portion 20A.

As shown in FIGS. 2 and 3, the adherend end portion 11 is formed in a cylindrical shape as a whole, and one end surface thereof is set as a seat surface 11A on which the attachment end portion 10A is provided, and the other side. Is set as a bonding surface 12 to be bonded to the bonding surface 21A of the transparent plate 21. The seat surface 11A supports the attachment end portion 10A so as not to fall down via a plurality of (four in the present embodiment) ribs 10C projecting perpendicular to the seat surface 11A. Yes.
As shown in FIGS. 2 to 5, the attachment surface 12 is formed in a shape having a bottom groove 12 </ b> A that partially separates the attachment surface 12 from the plate surface of the transparent plate 21 described above. Thereby, when the bonding surface 12 and the bonding surface 21A are bonded, the molten hot melt resin 32A (see FIG. 5) is completely extruded from between the bonding surface 12 and the bonding surface 21A. This can be prevented, and the adhesive strength by the above-mentioned adhesion can be secured.

  As shown in FIGS. 2 and 3, the groove-like recess 13 </ b> A forms the outer surface 13 on the outer surface 13 between the seating surface 11 </ b> A and the attaching surface 12. It is formed so as to surround it. Here, as shown in FIGS. 2 to 5, the bonded end portion 11 is formed so that a portion closer to the attaching surface 12 than the concave portion 13 </ b> A has a slightly smaller diameter. As a result, as shown in FIGS. 2 and 5, the recess 13A causes the molten hot melt resin 32A overflowing from between the affixing surface 12 and the joining surface 21A to flow and solidify as described above. The hot melt resin 14 can be solidified.

Further, as shown in FIGS. 2 to 5, the outer surface 13 is formed with a notch 11 </ b> B extending in a groove shape from the recess 13 </ b> A toward the seat surface 11 </ b> A described above. When the molten hot melt resin 32A flows into the concave portion 13A (see FIG. 5), the cutout portion 11B includes the air in the concave portion 13A and the molten hot melt resin 32A that has already been poured into the concave portion 13A. The substance is allowed to escape from the seating surface 11A side of the bonded end 11 to the outside.
According to the said structure, the flow path which escapes materials, such as molten hot-melt resin 32A which overflowed from between the affixing surface 12 and the joining surface 21A mentioned above by the notch part 11B provided in the to-be-adhered edge part 11. FIG. Can be set. This eliminates the need to precisely control the amount of hot melt resin to be adhered when the bonding surface 12 and the bonding surface 21A are bonded. Further, the flow path is set so that a substance such as the molten hot melt resin 32A escapes from the seating surface 11A side of the bonded end portion 11. Thereby, it can suppress that said substance adheres to the board surface of the transparent plate 21 mentioned above, and the board surface of this transparent board 21 becomes dirty.

As shown in FIG. 2, the recess 13 </ b> A has a support surface 13 </ b> B facing in a direction from the adherend end portion 11 to the attachment end portion 10 </ b> A (that is, a direction from the mark M <b> 2 to the mark M <b> 3 shown in FIG. 2). , And so as to surround the adherend end portion 11. The support surface 13B receives and supports the force applied to the solidified hot melt resin 14 that has flowed into the recess 13A and solidified in the direction from the bonded end 11 to the attachment end 10A. As a result, the bonding strength between the solidified hot melt resin 14 and the fastening material 10 can be further increased, and the bonding strength of the fastening material 10 to the transparent plate 21 can be improved. The effect of improving the bonding strength by the support surface 13B is particularly important when a hot melt resin having poor adhesion to the material (polypropylene) of the fastening material 10 is used.
The marks M1, M2, and M3 described in FIGS. 2, 4, and 5 are added for the sake of easy understanding of the direction on the fastening material 10, and do not actually exist. Is.

By the way, the above-mentioned fastening material 10 is integrally formed as a whole by injection molding using a thermoplastic resin (polypropylene in this embodiment) as a raw material. In this injection molding, the mold opening direction of the mold filled with the raw material is a direction perpendicular to the protruding direction of the pair of locking claws 10B (that is, the mark M1 and the mark M2 shown in FIG. 2). (Direction along a straight line). Thereby, the problem of an undercut can be solved with respect to each said latching claw 10B.
Further, the bottom groove 12A and the recess 13A described above are formed in a shape opened toward the mold opening direction of the mold as shown in FIGS. Thereby, since the mold opening of the mold is not restricted by the bottom groove 12A and the recess 13A, the fastening material 10 can be manufactured by injection molding using the mold. Can be mass produced.

Subsequently, a method of bonding and bonding the bonded end portion 11 of the above-described fastening material 10 to the bonding surface 21A of the above-described transparent plate 21 will be mainly described with reference to FIGS. 4 and 5. In addition, in the following, illustration and detailed description of ancillary processes such as a process of providing the coating layer 21B (see FIG. 2) on the transparent plate 21 are omitted.
When the fastening material 10 is bonded and bonded to the transparent plate 21, first, the fastening material 10 and the transparent plate 21 to be bonded to each other are prepared. Here, the step of preparing the fastening material 10 described above corresponds to the “fastening material preparation step” in the present invention.

Here, as shown in FIGS. 2 and 3, the fastening material 10 is formed with a concave portion 13 </ b> A having a shape opened toward the outer peripheral side of the bonded end portion 11 on the outer surface 13 of the bonded end portion 11. Has been.
Further, as shown in FIGS. 2 and 5, a coating layer 21 </ b> B for preventing the transparent plate 21 from being damaged is provided on the plate surface of the transparent plate 21. A joining surface 21A is set at a position where the fastening material 10 is to be joined on the coating layer 21B.

Next, the fastening material 10 prepared in the above-described fastening material preparation step is held by a holding portion 31 (see FIG. 4) in a joining jig 30 for joining the fastening material 10 to the transparent plate 21. This step corresponds to the “fastening material holding step” in the present invention.
In the fastening material holding step, the fastening material 10 is inserted into the holding portion 31 (see FIG. 2) formed in a cylindrical shape from the attachment end portion 10A side, and the attachment end portion 10A is locked by a lock member (not shown). It is held by being locked. As a result, the bonded end portion 11 of the fastening material 10 is covered with the side wall 31A of the holding portion 31 from the outer peripheral side of the bonded end portion 11 as shown in FIGS. Here, the adherend end portion 11 is formed such that a portion closer to the attaching surface 12 than the recess portion 13A has a slightly smaller diameter. For this reason, a gap 31B is formed between the small-diameter portion of the adherend end 11 and the side wall 31A.

The side wall 31 </ b> A is preferably formed of a material having high thermal conductivity and melting point and poor adhesion to the hot melt resin that bonds the fastening material 10 and the transparent plate 21. In the present embodiment, the side wall 31A is made of copper.
In this embodiment, the fastening material 10 is held at a holding position where the attachment surface 12 of the fastening material 10 slightly protrudes downward as viewed in FIG. 4 with respect to the side wall 31A of the holding portion 31. Is done. In the present specification, the holding position is also referred to as “predetermined holding position”.

By the way, the holding part 31 abuts the pressing piece 31C biased by the spring 31E on the seating surface 11A of the fastening material 10 described above. The pressing piece 31C is configured to slide along a slide groove 31D formed in the side wall 31A.
When the fastening member 10 is inserted deeper than the predetermined holding position (upward as viewed in FIG. 4) into the side wall 31A, the pressing piece 31C is directed toward the predetermined holding position. It is comprised so that the force which pushes back the said fastening material 10 may be added.

As shown in FIG. 4, the fastening material 10 held at the predetermined holding position of the holding portion 31 described above by the above-described fastening material holding step is melted hot from the molten hot melt resin supply portion 32 on the bonding surface 12. A melt resin 32A is supplied. The molten hot melt resin 32A is supplied by applying the fastening surface 12 of the fastening material 10 to the liquid surface of the molten hot melt resin 32A stored in a molten state in the molten hot melt resin reservoir 32C of the molten hot melt resin supply unit 32. It is carried out by immersing and adhering the molten hot melt resin 32A to the affixing surface 12.
Here, the bonding surface 12 of the fastening material 10 protrudes from the side wall 31A of the holding portion 31 at the predetermined holding position, so that the molten hot melt resin 32A does not adhere to the side wall 31A. The hot melt resin 32 </ b> A can be supplied to the pasting surface 12.

The molten hot-melt resin 32A stored in the molten hot-melt resin reservoir 32C is heated by the heating device 32B provided in the molten hot-melt resin supply unit 32, and the molten hot-melt resin 32A is converted into the molten hot-melt resin reservoir 32C. The whole is melted by heating.
Here, as the hot melt resin stored in the molten hot melt resin reservoir 32C, a resin that is in a molten state at a temperature lower than the softening point of a thermoplastic resin (polypropylene in the present embodiment) that is a raw material of the fastening material 10 is used. It is desirable. Accordingly, when the molten hot melt resin 32A is attached to the attachment surface 12 of the fastening material 10, the temperature of the molten hot melt resin 32A is set to a temperature lower than the softening point of the fastening material 10, and the fastening material 10 It is possible to prevent deformation due to softening due to high temperature.

As described above, the fastening material 10 supplied with the molten hot melt resin 32A is pressed against the bonding surface 21A of the transparent plate 21 by the bonding jig 30 described above, as shown in FIGS. Then, the molten hot melt resin 32A attached to the bonding surface 12 of the fastening material 10 is solidified to the solidified hot melt resin 14, whereby the bonding surface 12 is bonded to the bonding surface 21A. This step corresponds to the “bonding step” in the present invention.
The joining jig 30 is separated from the fastening material 10 after the bonding step, and is reused to bond and fasten another fastening material 10 to another joining surface 21A of the transparent plate 21. The

In the bonding step, the holding unit 31 of the bonding jig 30 releases the lock by the above-described lock member (not shown) from the state in which the bonding surface 12 of the fastening material 10 faces the bonding surface 21A. Then, the side wall 31A described above is brought into contact with the coating layer 21B around the bonding surface 21A.
