Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to window materials made of transparent plate-like bodies, particularly glass plates, synthetic resin plates, etc., such as flat plate-shaped, bent plate-shaped raw or reinforced Architectural window materials, vehicle preparation materials, etc. made of veneer, laminated, laminated, multi-layered, and coated with membranes on the surface of the panels, etc.
In particular, the present invention relates to a window material with an assembly formed by integrally molding a synthetic resin molding or a gasket (hereinafter referred to as molding) directly on the outer surface of the peripheral edge of an automobile window material, 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 encapsushi 292 method, in which a molded product is easily attached to the vehicle body using adhesive or the like, is being adopted.

Among them, a metal coating film such as aluminum or chromium is applied to the outer surface of the molding or gasket for decoration after molding, or it is attached by plating or vapor deposition, and semi-rigid polyvinyl chloride or For example, Japanese Patent Application Laid-Open No. 54-1000 suggests reinforcing it with metal bands and fixing it to the vehicle body through protrusions.
This method is known as described in Japanese Patent Publication No. 22, Japanese Patent Publication No. 61-7368, and the like.

[Problem that the invention seeks to solve]

Among the conventional methods mentioned above, Japanese Patent Application Laid-Open No. 54-1000
The methods disclosed in Publication No. 22 and Japanese Patent Publication No. 61-7368 have simple structures for moldings and gaskets, and can be attached to the vehicle body using a simpler adhesive method than the physical fixing method, and are likely to become widely used. However,
pasting aluminum and chrome films after molding,
Alternatively, decoration and exterior are done by masking and applying plating, vapor deposition, etc., or by setting metal bands etc. in the mold during injection molding, so these attachments, Plating vapor deposition work is complicated and inefficient, and it is difficult to fix the metal band etc. in a predetermined position in a mold during injection molding, and if it moves, it is likely to shift and cause deformation. Furthermore, when a metal band, etc. is set in the mold and molten resin is injected into the cavity space, the resin wraps around between the metal band, etc. and the inner surface of the mold. After being removed from the mold, there were problems such as the tendency for flakes to form on the outer surface of the metal band or the like.

[Means for solving problems]

The present invention has been made in view of the above-mentioned drawbacks of the conventional art, and is provided with a spring mechanism that presses a decoration, reinforcing member, or stopper member, etc. from the surface of the transparent plate to the inner surface of the mold inside the cavity. The object of the present invention is to provide a window material with an assembly and a method for manufacturing the same, which can solve the above-mentioned problems by integrally molding a molding or a gasket on a transparent plate-like body.

That is, the present invention provides an assembly window material for a vehicle, which is formed by 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, and in which the window material is used as a substrate during assembly of the window material. A window material with assembly, characterized in that a decorative/reinforcing member or a stopper member supported by a spring mechanism member is integrally provided so as to face the outer surface of the molding or gasket, and a transparent plate-like member. In a method of forming a molding or a gasket made of synthetic resin on the outer surface of the peripheral edge part, the peripheral edge part of the transparent plate-shaped body is placed in an injection mold, and the peripheral edge part of the transparent plate-shaped body is used as a substrate to form a spring. Decorative/reinforcing members and stopper members are arranged and positioned so as to be pressed and fixed to the inner surface of the mold via mechanical members, and by clamping the mold, the transparent plate-like body is held between the clamping parts of the core mold member via the cushioning material. and injecting a molten synthetic resin or its raw material while mixing and reacting into a cavity space constituted by the inner surface of the mold, the outer surface of the peripheral edge of the plate-shaped body, and the inner surface of the decorative/reinforcing or stopper member;
The present invention provides a method for manufacturing a window material with an assembly, which is characterized in that the window material is cured and integrally molded and then taken out from the mold.

Here, the term "transparent" in the transparent plate-like material refers to transparent, translucent, colored, uneven surface patterns, etc.;
Various types of glass for doors, etc., such as flat glass, tempered plate glass by heat treatment or chemical treatment, laminated glass of various degrees including glass plates and resin plates, and laminated layers with various surface treatments such as heat ray reflective coating, tear prevention coating, black frame, etc. These include glass, various inorganic glasses such as bent sheet glass and double-layer glass, polycarbonate, acrylic, hard-coated synthetic resin plates such as scratch-resistant, and laminates made of these synthetic resin plates and inorganic glass plates.

The molding that is integrally molded on the transparent plate-like body is applied to the peripheral edge of the transparent plate-like body, covering the entire circumference or almost the entire circumference of the transparent plate-like body, and various shapes are adopted for the molding, but at least transparent It is integrally molded on one side of the front and back of the peripheral edge of the plate and on the end surface, and it goes without saying that it is preferable to apply Pflimer to the required areas in advance to improve the adhesive strength. The surface 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 part has an uneven shape or a shape that has some kind of spring effect, and furthermore, a protrusion (for sealing) is provided around the entire circumference of the transparent plate-like body on the rising surface corresponding to the end face side of the transparent plate-like body. Alternatively, it is preferable to make it airtight by incorporating a flexible hollow tube within the surface thereof, and also for adhesive fixation and engagement fixation when aligning and installing it to an opening in a vehicle body, etc. The back side of the molding has an uneven or concave shape to prevent the bead-shaped adhesive applied to this part from escaping, 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 material at the vehicle body opening, fixing it 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

It has the advantage that it is injected into the cavity space at a pressure of around cn1, and that it can mix two components by collision and perform reaction injection 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 material that doubles as a buffering member or a sealing member different from the injected resin so as not to damage or destroy the surface of the body, and also to prevent the generation of paris or to absorb deformation of the mold and deformation of the transparent plate-like body; For example, heat-resistant fluororesin or fluorocarbon rubber, silicone resin or silicone rubber, other soft resins, foams, hollow bodies, etc.
It goes without saying that the elastic body of the composite body may be interposed between the transparent plate-like body and the mold surface and sealed.

Decorative/reinforcing members or stopper members set in the mold can be made of metal or resin films, or objects of various sizes, thicknesses, and shapes, such as civilian objects or Nandos. Since it is set by the mold, it can be firmly clamped and fixed to the transparent plate inside the mold in conjunction with the mold clamping, and it can also absorb mold distortion and distortion of the transparent plate, and the position can be adjusted even when pouring synthetic resin. It allows for accurate positioning without causing curling, and after the synthetic resin has solidified from a liquid state, the spring force can be eliminated by the resin, making it sturdy, and depending on the synthetic resin used, The strength of the spring force can be freely selected, and various materials and materials can be selected for the spring mechanism, but springs are preferred.

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 polyethylene, polystyrene, polypropylene, silicone resins, polyamide 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 7V4, as well as vinyl ester resins, epoxy resins, silicone resins, and unsaturated polyesters. Examples include thermosetting resins such as resins, blend resins, foamed polyurethane, elastomers and elastic rubbers, etc., which can be widely used, as well as ultraviolet absorbers, colorants,
It goes without saying that fillers such as catalysts, blowing agents, and stabilizers may be added to control the reaction rate, as well as reinforcing agents such as glass fibers and glass flakes, which improve the spring force of the spring mechanism. In addition to determining the strength of elastic force, it is also necessary to consider weather resistance, heat resistance, strength, thermal expansion coefficient, shrinkage ratio, surface texture, etc.

[Effect]

As mentioned above, according to the window material with assembly and the manufacturing method thereof of the present invention, various decorative/reinforcing members and stopper members are selected and combined in various ways based on the spring force and holding force of the spring mechanism and the physical properties of the synthetic resin of the molding itself. Since it can be molded in one piece, it provides even more advanced effects.

In other words, the spring force of the spring mechanism makes it possible to reliably position decorative/reinforcing members, stopper members, etc. within the formwork, and also to hold the transparent plate-like object without applying excessive loads. It is a measure that can absorb the deformation of the spring mechanism, does not cause positional shift when injecting liquid synthetic resin, and can prevent the occurrence of cracks on decorative/reinforcing members and stopper members. Decorative/reinforcing members and fastening members can be integrally molded with a variety of sizes, thicknesses, and shapes depending on the holding force, eliminating variations in finishing accuracy and positioning accuracy between each member, making it easy to install in openings on the outside of the vehicle body. The finished product has a beautiful appearance without the need for the subsequent work of attaching or gluing these parts, and it also makes full use of the physical properties of the synthetic resin that is integrally molded, allowing for the freedom to choose from a wide range of highly functional moldings, such as By increasing its own elastic force, it can flexibly respond to variations in surface inclination accuracy and distortion between window frame materials and frames such as car body outer panels, and the sealing performance and adhesion/fixing performance between them is also extremely improved. This improves the maintenance of watertightness and airtightness, increases the holding power and durability of the transparent plate, and can be easily installed by a mechanical robot without creating stress during work. It can be adapted to automation, and the transparent plate-like body will not be damaged or damaged during installation.
