And a method for manufacturing the same.

[Conventional technology]

Conventionally, as a means for attaching a transparent plate such as a glass plate to the opening of a vehicle window, in an automobile, it is fitted into the joint between the inner panel and the outer panel of the vehicle body and the peripheral edge of the glass plate. A glass plate is attached to the car body via a separately molded weather strip, and the leg between the glass plate and the peripheral edge of the glass plate mounting flange of the car body panel is inserted and fixed with an adhesive. The so-called direct glazing method using the peripheral edge molding is adopted, and as a mounting means which has been attracting more attention recently, a molding or a gasket by a reaction injection molding method or the like is directly integrally molded on the outer peripheral surface of the glass plate in advance. The so-called encapsulation method is used to easily attach things to the vehicle body with one touch by gluing etc. Is being use.

Among them, for example, Japanese Patent Application Laid-Open No. 61-66645 describes a window member assembly and a method for manufacturing the same, which includes a main body made of a transparent plate material and a transparent body which is superposed on at least one side of the main body and is attached thereto. A synthetic resin material layer, a gasket having in-situ formed and adhered gaskets at the peripheral portions of these two parts, and a manufacturing method thereof are disclosed, and a laceration preventive window material assembly is known.

Further, Japanese Utility Model Laid-Open No. 61-158508 discloses a windshield glass detaching structure, a holding means for detaching the glass from the vehicle body by an impact of a predetermined value or more on the windshield glass, and a gap between the glass and the vehicle body. Which is attached directly to or via a holding means and has an absorbing means for absorbing the energy received by the glass when the glass is moving, and is intended to reduce the collision load of the occupant on the windshield glass in the event of a vehicle emergency. Etc. are known.

As described above, the conventional one disclosed in Japanese Patent Laid-Open No. 61-66645 is intended to prevent laceration by providing a transparent synthetic resin material layer on a transparent plate material. A polymer frame member is formed on-site so as to surround the peripheral edge portion, and both the transparent plate material and the synthetic resin material layer are made to have sufficient adhesion at the peripheral edge portion, rather, a transparent plate material. And the synthetic resin material layer is firmly fixed, and the polymer frame member itself surrounding the peripheral edge of the window material is not always sufficient to absorb impact energy at the time of collision. There is no such thing. Further, in the one disclosed in Japanese Utility Model Laid-Open No. 61-158508, the member provided at the end of the windshield glass has a complicated shape, the number of members is large, and the structure of the holding and absorbing means is complicated. There is a problem that the dimensions are required to be highly accurate, the mounting work is inefficient, and the instrument panel of the vehicle body also needs a certain shape.

[Means for solving problems]

The present invention has been made in view of the above-mentioned drawbacks of the related art, and through-holes are provided at required positions of the through-holes of the transparent plate-like body as needed so that the insertion member does not directly contact the transparent plate-like body. By doing so, various through holes can be utilized, and a window member and a method for manufacturing the same that can solve the above problems are provided.

That is, according to the present invention, in a window member formed by integrally molding a molding or gasket of synthetic resin on the outer surface of the peripheral portion of the transparent plate member, at least one or more holes are formed at required positions of the peripheral portion of the transparent plate member. A through hole is formed by inserting the through hole into the molding or the gasket, and the through hole faces the inner peripheral surface of the through hole facing the surface coated with the synthetic resin. A window member formed by integrally molding the above.

Further, the window member described above, characterized in that the through hole is integrally molded so as to be a substantially cylindrical member fitted into the through hole.

In the method of integrally molding a molding or gasket of synthetic resin on the outer surface of the peripheral portion of the transparent plate, a predetermined portion of the peripheral portion of the transparent plate is placed in a molding die and the peripheral edge of the transparent plate is After positioning at least one or more through-holes drilled in the required parts of the parts and the substantially cylindrical protrusions provided on the upper and lower mold members so as to have substantially the same central axis,
The transparent plate-shaped body is sandwiched between the sandwiching portions of the two mold members via a seal material that also functions as a cushioning material, and the substantially cylindrical projections of the upper and lower mold members come into contact with each other to make the inner surface of the mold member transparent. A cavity formed by the outer surface of the peripheral edge of the plate-like body is formed, synthetic resin is injected into the cavity, and the inner peripheral surface of the through hole faces the surface covered with the synthetic resin. A method of manufacturing a window member, comprising integrally molding a sail or a gasket having holes and then taking out the mold from the mold.

Further, the cavity space is formed by being formed by an inner surface of the upper and lower die members, an outer surface of the peripheral edge portion of the transparent plate-like body, and an outer surface of a substantially tubular member that is fitted into the through hole and reaches the surface of the upper and lower die members,
Synthetic resin is injected into the cavity space, and the molding or the gasket having the through hole formed by the substantially cylindrical member reaching the front and back surfaces of the molding or the gasket by being inserted into the through hole is integrally molded. And a method for manufacturing the window member described above.

Here, the transparent of the transparent plate-like member means that it includes transparent, semi-transparent, colored and surface irregular patterns, etc., and the plate-like member is used for building construction or for vehicles such as automobile front, rear, door, etc. Various glass of, namely flat glass, tempered glass by heat treatment or chemical treatment, various laminated glass including glass plate or resin plate and heat ray reflective film, laceration preventive film, laminated glass having various surface treatments such as black frame, Examples include bent sheet glass, various types of inorganic glass such as layered glass, hard-coated synthetic resin plates such as polycarbonate, acrylic and scratch resistance, and a laminate including these synthetic resin plates and inorganic glass plates.

The size of the through hole formed in the peripheral edge of the transparent plate-like member is such that even if at least a spring mechanism member is fitted, the inner peripheral surface of the through hole is covered with synthetic resin so that it does not come into direct contact with the hole. However, it is necessary to have various diameters and shapes similar to through-holes, and the number should be at least one at the required location on the entire circumference. Is better in terms of strength, but may be used elsewhere.

The through-hole may be a cylindrical or bellows-like substantially tubular member, and a cylindrical or bellows-like substantially tubular member which is fitted into the through hole and reaches both surfaces of the molding or the gasket is set. The through hole may be integrally molded. The substantially tubular member is preferably made of synthetic resin, but may be made of metal or the like. However, in the case of a rigid body such as metal, it is important to have an outer diameter that does not contact the through hole.

Regarding the molding integrally molded with the transparent plate-shaped body, it is applied to the peripheral portion of the transparent plate-shaped body over the entire circumference or almost the entire circumference, and various shapes of the molding are adopted, but at least transparent. It is needless to say that it is preferable to integrally mold one of the front and back sides and the end surface of the peripheral portion of the plate-shaped body, in which case it is preferable to apply a primer in advance to the required portions to improve the adhesive strength,
It is preferable that the outer surface of the molding has a shape that does not cause unpleasant wind noise such that it fills a more aerodynamic structure, and that a tongue portion is provided to improve the sealing performance with the vehicle body outer panel, It is preferable that the back surface of the tongue portion has an uneven shape or a shape having a spring effect from any shape,
Furthermore, a protrusion (for sealing) should be provided on the rising surface, which is the end face side of the transparent plate, over the entire circumference of the transparent plate, or a flexible hollow tube should be built in the surface so that it can be sealed. Is preferable, and for the purpose of adhesive fixing and engagement fixing when aligning with the opening of the vehicle body or the like, the back surface of the molding is applied in an uneven or concave shape to this portion. To prevent the bead-like adhesive from leaking and to provide a dam part at the end for the purpose of sealing, position the window member at the vehicle body opening, fix it until the adhesive is fixed, and fix the auxiliary agent after that. It is preferable to provide at least one locking rib portion that also serves as the locking rib portion.

As the method for forming the molding, a general synthetic resin molding method such as an injection molding method can be adopted, and in particular, RIM method (Reaction Injection Molding), R-RIM method (particularly, a reinforcing material thereof is mixed), LIM method (Liquid Injection
Molding) and the R-LIM method (particularly those in which the reinforcing material is mixed) can be mentioned, and among them, the method by the RIM method is preferable. That is, typically about 20
While it requires 0 to 300 ℃ and the temperature of the mold part surrounding the cavity space, 100 ℃ to room temperature, preferably 50 to 80
It may be as low as ℃, and it is preferable to control the temperature of the mold holding temperature as well as the temperature of the non-molded portion so that the solidification rate can be controlled.
~1000kg / cm ² and very high those requiring pressure from atmospheric pressure to about 6 kg / cm ² in the range of about, it is injected into preferably the cavity space with a pressure of about 3 kg / cm ² before and after, for example, have a very low pressure 2 It has the advantage that the components are collision-mixed and the reaction is injected. The mold itself is not particularly limited, and it may be made of a very general metal, resin, or ceramic, and the surface of the cavity space may be treated with a mold release agent or a transparent plate shape. A substance that also serves as a sealing member that is a different buffer material from the injected resin so as not to damage or destroy the surface of the body and to prevent burrs or to absorb mold deformation and deformation of the transparent plate-like body , For example, heat-resistant fluororesin or fluororubber, silicon resin or silicon rubber, or other soft resin etc. simple substance, foam, hollow body, or composite elastic body is interposed between the transparent plate-like body and the wall surface for sealing. Needless to say.

Examples of the synthetic resin used in the various molding methods, that is, the synthetic resin usable in the present invention are, for example, polyurethane resin, low density and high density polyethylene, polystyrene, polypropylene, silicon resin, polyamide resin, nylon-6. , EVA, PET, PBT and other thermoplastic resins,
Alternatively, polyurethane-based, ethylene-vinyl acetate-based, polyolefin-based, styrene-butadiene-based thermoplastic rubber,
There are thermosetting resins such as vinyl ester resin, epoxy resin, silicone resin, unsaturated polyester resin, etc. In addition, blended resin, polyurethane foam, elastomer, elastic rubber, etc. can be widely adopted. Further, it goes without saying that a UV absorber, a colorant, a catalyst for controlling the reaction rate, a filler such as a foaming agent and a stabilizer, and a reinforcing agent such as glass fiber and glass flakes may be added. In addition, it is necessary to consider weather resistance, heat resistance, strength, coefficient of thermal expansion, rate of reduction, surface properties and the like.

[Operation] As described above, according to the window member of the present invention and the method for manufacturing the same, the transparent plate and the sail or the gasket are communicated with each other so that the insertion member does not come into direct contact with the through hole of the transparent plate, and the front and back of the molding or the gasket. By integrally molding the through-holes reaching both sides, by using the through-holes in various ways according to the purpose, a more functional molding or gasket can be obtained, and various peculiar window members can be obtained. Is what you can do.

That is, for example, when the window member of the present invention is attached to the vehicle body outer plate of the vehicle opening, if the through hole of the window member is used, the adhesive is applied in advance to the back surface recess of the conventional molding or gasket, and then Instead of carrying out the mounting work, the mounting mechanism and the adhesive injection mechanism can be integrated into one robot, and the mounting, fixing and bonding work can be completed almost simultaneously in one process. When the reinforcement member is attached to the outer surface of the molding or the gasket and attached to the outer plate of the vehicle body, the spring mechanism member fixed to a required position on the rear surface of the member is inserted into the through hole to secure the spring mechanism member on the rear surface of the molding or the gasket. If the structure is fixed by the stop member, the spring mechanism member is independent of the molding or gasket, so its spring force and holding So it can be exhibited as it is ability,
For the molding or gasket, a synthetic resin with sufficient flexibility and elasticity can be selected and used so as to match the spring force and holding force at any time, and when mounting on the vehicle body outer plate, the molding or gasket rear surface as well as the spring mechanism member back surface The transparent plate-like body can be held more flexibly, and the impact energy of the object can be absorbed, and the impact load on the windshield glass of the occupant can be reduced and alleviated even when the vehicle collides. Furthermore, it is possible to flexibly deal with unevenness of surface inclination accuracy between the window member and the frame part such as the vehicle body plate and unevenness such as distortion, thereby further improving the sealing property, the adhesion and the fixing property. It is possible to improve the maintenance of airtightness and airtightness, stress is not generated, and it is possible to easily advance robotized automation by machines. As a result, the transparent plate-like body will not be damaged or broken, and in particular, the breakage or breakage will not occur from the through holes formed in the transparent plate-like body. The skin layer constituting the surface layer itself can be aesthetically finished.
