Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to window members made of transparent plate-like bodies, particularly glass plates, synthetic resin plates, etc., such as flat plate-shaped, bent plate-shaped raw or reinforced Single-panel, laminated, laminated, multi-layered, architectural window members and vehicle window members whose surfaces are treated with a film, etc., especially synthetic resin moldings or gaskets directly on the outer surface of the periphery of automotive window members. This invention relates to a window member formed by integrally molding the same, and a method for manufacturing the same.

[Conventional technology]

Conventionally, the means for attaching transparent plate-like bodies such as glass plates to vehicle window openings has been to fit them into the joint between the inner panel and outer panel of the vehicle body and the peripheral edge of the glass plate. The glass plate is attached to the car body through a separately molded weather strip, and the legs are inserted between the glass plate and the periphery of the glass plate mounting flange on the car body panel and fixed with adhesive. The so-called direct glazing method, which uses a molded peripheral molding, has been adopted, and the mounting method that has been attracting attention recently is to directly integrate a molding or gasket onto the outer surface of the peripheral edge of the glass plate in advance using a reaction injection molding method, etc. The so-called encapsulation method is being adopted, in which the shaped material is easily attached to the vehicle body by bonding or other means.

Among them, for example, Japanese Patent Application Laid-Open No. 61-66645 describes a window material assembly and its manufacturing method, which includes a main body made of a transparent plate material and a transparent material overlaid and attached to at least one side of the main body. Tear-resistant window assemblies are disclosed having layers of synthetic resin material and gaskets formed and bonded in-situ around the peripheries of these areas and methods of making the same.

Furthermore, Japanese Utility Model Application Publication No. 61-158508 describes a windshield glass detachment structure, which includes a holding means for detaching the glass from the vehicle body when an impact to the windshield glass exceeds a predetermined value, and a gap between the glass and the vehicle body. Disclosed is an absorbing means attached directly to the windshield or through a holding means to absorb energy received by the glass when the glass moves, and is intended to reduce the collision load of an occupant against the windshield glass in the event of a vehicle emergency. etc. are known.

[Problem that the invention seeks to solve]

As mentioned above, the conventional method described in JP-A No. 61-66645 is intended to prevent tearing by providing a layer of transparent synthetic resin material on a transparent plate material. A polymer frame member is formed on-site to surround the peripheral edge, and both the transparent plate material and the synthetic resin material layer are intended to have sufficient adhesion at the peripheral edge, but rather the transparent plate material The aim is to sufficiently adhere the synthetic resin material layer to the window material, and the polymer frame member surrounding the peripheral edge of the window material itself is not necessarily sufficient to absorb impact energy in the event of a collision. It's something that doesn't exist.

Furthermore, the structure described in Japanese Utility Model Application Publication No. 61-158508 has complicated shapes and a large number of members provided at the ends of the windshield glass (and the structure of the holding and absorbing means is also complicated). However, there were other problems, such as the need for large dimensions, the inefficient installation work, and the need for a certain shape for the instrument panel of the car body.

[Means for solving problems]

The present invention has been made in view of such drawbacks of the conventional art, and by integrally molding through-holes by providing through-holes at appropriate locations in the transparent plate-like body so as not to contact the transparent plate-like body, It is an object of the present invention to provide a window member and a method for manufacturing the same that can solve the above-mentioned problems by making the through-holes usable in various ways.

That is, the present invention provides a window member in which a molding or a gasket made of synthetic resin is integrally molded on the outer surface of the peripheral edge of a transparent plate, in which at least one transparent plate is provided at a predetermined location on the peripheral edge of the transparent plate. 1. A window member characterized in that the window member is integrally molded to provide a through hole that extends through the through hole and reaches both the front and back surfaces of the molding or gasket.

Also, in a method of integrally molding a molding or a gasket made of synthetic resin on the outer surface of the peripheral edge of a transparent plate-like body, a predetermined portion of the peripheral edge of the transparent plate-like body is placed in a mold, and the transparent plate-like body After positioning so that at least one through hole drilled at a predetermined location on the peripheral edge and the substantially cylindrical protrusion provided on the upper and lower mold members are aligned with the same central axis, the transparent plate-like body is placed between the two mold members. The upper and lower mold members are held together via a sealing material that also functions as a buffer material, and the substantially cylindrical protrusions of the upper and lower mold members come into contact with each other to form the inner surface of the mold member and the outer surface of the peripheral edge of the transparent plate-like body. To provide a method for manufacturing a window member, which comprises forming a cavity space, injecting a synthetic resin into the cavity space, integrally molding a sail or gasket having a through hole, and then removing the sail or gasket from the mold. .

The through-holes to be drilled in the peripheral edge of the transparent plate-like body may have various diameters as needed so that at least the spring mechanism member etc. will not come into direct contact even if they are fitted therein, and the shape may be similar to that of a through-hole. Usually, at least one is required at a required location around the entire circumference, and it is better to provide it at the same cross section as the locking rib for strength, but it may be provided at other locations.

The through hole may be a cylindrical or bellows-shaped substantially cylindrical member, and the cylindrical or bellows-like substantially cylindrical member may be set to fit into the through hole and reach both surfaces of the molding or gasket. The through hole may be integrally molded. The substantially cylindrical member is preferably made of synthetic resin, but may be made of metal or other materials. However, in the case of a rigid body such as metal, it is important to set the outer diameter so that it does not come into contact with the through hole.

The molding that is integrally molded onto the transparent plate-like body is applied to the peripheral edge of the transparent plate-like body over the entire circumference or almost the entire circumference, and various shapes are adopted for the molding, but at least transparent It is integrally molded on one of the front and back sides and the end face of the peripheral edge of the plate-shaped body, and it goes without saying that it is preferable to apply a primer to the required areas in advance to improve adhesive strength.
The outer surface of the molding preferably has a shape that satisfies a more aerodynamic structure and does not cause unpleasant wind noise, and is preferably provided with a tongue portion to improve sealing performance with the outer skin of the vehicle body. It is preferable that the back surface of the tongue piece has an uneven shape or a shape that has some kind of spring effect, and furthermore, a protruding piece (seal) is provided on the rising surface corresponding to the end face side of the transparent plate-like body over the entire circumference of the transparent plate-like body. It is preferable to make it possible to seal it by providing a flexible hollow tube inside the surface of the tube or by incorporating a flexible hollow tube into the surface of the tube.Furthermore, it is suitable for adhesive fixing and engagement when aligning and installing it in an opening in the vehicle body, etc. For fixing, the back side of the molding has an uneven or concave shape to prevent the bead-shaped adhesive applied to this area from leaking, and a dam part is provided at the end for the purpose of sealing. It is preferable to provide at least one locking rib portion for positioning the member at the vehicle body opening, fixing the member until the adhesive is fixed, and assisting with subsequent fixing.

The method for molding the molding can be a general synthetic resin molding method such as an injection molding method, and in particular RIM
Reaction Injection Moldi
B), R-RIM method (particularly those containing reinforcing materials), LIM method (Liquid Injection
Molding), R-L 1M method (particularly those containing reinforcing materials), among which RI
It is preferable to use the M method. That is, while the temperature of the part of the mold surrounding the cavity space generally requires about 200-300°C, for example, the temperature of the mold part surrounding the cavity space is about 100°C-
Room temperature, preferably as low as 50 to 80°C, is sufficient, and it is preferable to be able to control the temperature of not only the mold holding temperature but also the non-molded part, since it is possible to control the solidification rate, etc. ~1000kg/cI
A and those that require extremely high pressure are normal pressure ~ about 6 m2/
It has the advantage that it is injected into the cavity space at a pressure of approximately 3 kg/cd, preferably around 3 kg/cd, and allows, for example, two components to be collided and mixed and then reacted and injected at an extremely low pressure. The mold itself is not particularly limited, and may be made of extremely common metal, resin, or ceramic, and the surface of the cavity space may be treated with a mold release agent, or a transparent plate-like material may be used. A substance that doubles as a sealing material and a buffering material different from the injected resin, so as not to damage or destroy the surface of the body, and to prevent the generation of paris or to absorb deformation of the mold and the deformation of the transparent plate-like body. For example, a heat-resistant fluororesin or fluororubber, silicone resin or silicone rubber, or other soft resin or other elastic body, such as a single body, a foam, a hollow body, or a composite body, is interposed between the transparent plate-like body and the mold surface and sealed. It goes without saying that there are many things to do.

Synthetic resins used in the various molding methods described above, that is, synthetic resins that can be used in the present invention, include, for example, polyurethane resins, low-density and high-density polyethylenes, polystyrene, polypropylene, silicone-based resins, polyamide-based resins, and nylon-6. , thermoplastic resins such as EVA, PET, and PBT, or thermoplastic rubbers such as polyurethane, ethylene-vinyl acetate, polyolefin, and styrene-butadiene, as well as vinyl ester resins, epoxy resins,
Examples include thermosetting resins such as silicone resins and unsaturated polyester resins, as well as blended resins, polyurethane foams, elastomers and elastic rubbers, which can be widely used, as well as ultraviolet absorbers, colorants, It goes without saying that fillers such as catalysts, blowing agents, and stabilizers that control the reaction rate, as well as reinforcing agents such as glass fibers and glass flakes, may be added. It is necessary to take into account strength, coefficient of thermal expansion, shrinkage ratio, surface texture, etc.

[Effect]

As described above, the window member and the method for manufacturing the same of the present invention allow the transparent plate body and the sail or gasket to be connected without contacting the through holes in the transparent plate body, and the through holes reaching both the front and back sides of the molding or gasket can be formed. By integrally molding, the through-holes can be used in various ways depending on the purpose, making it possible to obtain moldings or gaskets with more functionality, and making them into a variety of unique window members. .

That is, for example, when attaching the window member of the present invention to the outer panel of the vehicle body at the vehicle opening, if the through hole of the window member is used, an adhesive is previously applied to the recessed part of the back surface of the conventional molding or gasket, and then Instead of having to perform installation work, the installation mechanism and adhesive injection mechanism are integrated into one robot, allowing the installation, fixing, and gluing work to be completed almost simultaneously in one process. Also, for example, when attaching a decorative/reinforcing member to the outer surface of the molding or gasket and attaching it to the outer skin of the vehicle body, a spring mechanism member fixed at a predetermined position on the back surface of the member is inserted into the through hole and attached to the back surface of the molding or gasket. If the spring mechanism member is fixed by the stopper member, the spring mechanism member is independent of the molding or gasket, and its spring force and holding force can be used as is.
The molding or gasket can be made of a sufficiently flexible and elastic synthetic resin that can be selected to match the spring force and holding force as required.Moreover, when it is attached to the outer panel of the car body, it can be used to stop the spring mechanism member together with the molding or the back of the gasket. The back side of the component can also be adhesively fixed at the same time, making it possible to hold the transparent plate more flexibly, absorbing the impact energy of objects, and reducing the impact load on the windshield glass of the occupants in the event of a vehicle collision. In addition, it can flexibly respond to irregularities such as variations in surface inclination angle and distortion between the window member and the frame of the vehicle body outer panel, thereby improving sealing performance, adhesion, and fixing performance. It is possible to improve the maintenance of watertightness and airtightness, and there is no stress, and it is possible to easily advance robotization and automation using machines. etc. will never occur,
Moreover, the appearance can be finished with an aesthetic appearance by the decorative/reinforcing members and the skin layer that constitutes the resin surface layer itself.
