Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to window members made of plate-shaped bodies, particularly glass plates, synthetic resin plates, etc., such as flat or curved plate-shaped raw or reinforced window members. The present invention relates to a plate-shaped body with a holder member that can be used as a door member, especially for vehicles that require lifting and lowering, and movable window glass for automobiles.

[Conventional technology]

Conventionally, for movable automotive window glass, a separately molded metal or synthetic resin holder is fixed to the window glass with adhesive or cushioning adhesive tape, or by tightening metal fittings into the mounting hole. It is held.

For example, Japanese Utility Model Publication No. 53-25931 describes a holder for a vehicle window glass, and in the window glass holder provided between the vehicle window glass and a vertical movement mechanism for moving the window glass up and down, A U-groove that can hold the lower edge of the window glass and a hard synthetic resin holder with a nut embedded in the hole are molded, and the inside surface of the U-groove has thin irregularities to improve the adhesion of the adhesive. It is disclosed that protrusions are formed on both ends of the U-groove to prevent the adhesive from extruding at the same time as the holder is molded. ,
A process in which an adhesive tape with an adhesive layer coated with an adhesive is applied to the bottom or both sides of the window glass at the location where the glass support member of an automobile window glass is attached, and is fixed in a U-shape, and the adhesive tape is bonded to the adhesive layer. It consists of a process of applying a solvent to melt the adhesive, and a process of press-fitting the same part into a slightly narrow U-shaped groove of a glass support member while the adhesive remains in a molten state. It is known that a method of joining an automobile window glass and a glass support member is described, and that a U-shaped groove forms a number of horizontal grooves on the inner surface of the groove.

[Problem that the invention attempts to solve]

As mentioned above, when molding the holder separately, it is necessary to create a complicated shape, such as the need to provide protrusions to prevent the adhesive from extruding and a large number of finely uneven surfaces to strengthen the adhesive force. The components are complex and are prone to molding defects, and when bonding the holder to the window glass, it takes a long time for the adhesive to dry and solidify. However, the curvature of the holder and the window glass is likely to be distorted during the drying and fixing process, making it impossible to attach the window glass to the vehicle. In rare cases, the glass deteriorates and separates, and adhesion using adhesive tape reduces the frictional resistance during press-fitting the glass, creates only a small amount of constriction pressure, and provides a strong enough bond to withstand large loads. However, this is not always the case, and the work of adhesion and solidification cannot be completed in a short period of time, so these cannot be said to be sufficient.

On the other hand, in recent years, there has been a trend toward larger and thinner plate-shaped objects, especially window glass.For example, in the case of automobile window glass, there are many hard-top and suspensionless vehicles for the purpose of reducing weight and appearance, and the guide channel fixing part is becoming stronger. In addition, there is a strong trend toward luxury products, and it is important to make use of the space within the door frame to store and install other accessories, or to add various functions to the inner panel of the door. It is also desired to have the following properties, but this is not necessarily fully satisfactory.

[Means to solve the problem]

The present invention has been made in view of the above drawbacks of the conventional method, and in addition to integrally molding the holder member to the plate-shaped body and directly fixing it, the present invention has a bulge at the end edge of the plate-shaped body so as to have a circular cross-section. By making it an arcuate edge surface,
The present invention provides a plate-like body with a holder member that is strongly integrated on the plate-like body side.

That is, an end edge surface having an arcuate cross section that is more convex than the thickness of the plate member is provided at a predetermined location on the edge portion of the plate-like body, and the edge face having an arcuate cross-section and the front and back surfaces of the corresponding peripheral edge portion are surrounded. The present invention provides a plate-like body with a holder member, which is integrally molded with resin.

Here, the required location on the peripheral edge of the plate-like body where the holder member is integrally molded is preferably the lower edge side of the plate-like body, but depending on the raising/lowering method and opening/closing method of the plate-like body, The holder member may be placed on the side edge side or the upper edge side of one or both of the holder members, and the number of integrally molded holder members may be one piece in a wide area or may be divided into two or more pieces,
The selection depends on the above-mentioned lifting/lowering and opening/closing method, balance due to the size of the plate-shaped body, weight, shape, etc.

Further, the edge surface having an arcuate cross section provided on the plate-shaped body can be formed by applying electricity between a pair of electrodes, using a gas burner, far-infrared rays, or even a laser in some cases. By raising the temperature to the flow temperature range of glass, the edge surface of the plate-shaped body is formed into a substantially uniform arcuate cross-section,
The planar shape of the edge surface of the integrally molded surrounding holder portion may be linear in the direction perpendicular to the direction in which the lifting force acts, for example.
A combination of straight and diagonal or mountain shapes provides better balance, and
A planar convex strip is provided on the plate-like body, a mountain-like groove is provided in the center of the planar convex strip, and a screw hole is provided in the section to fix a guide channel, etc. for coupling to the lifting device. Then, the plate-shaped body itself is also fixed, and the fixation between the plate-shaped body and the holder member becomes stronger, which leads to reduction in weight, size, and thickness.

Furthermore, even if the planar shape of the lower edge of the plate-shaped body is made into the minimum necessary curved shape to accommodate movable devices such as lifting equipment, the curved shape makes it extremely difficult to chamfer the complex curved edge surface. The purpose can be achieved by making the lower edge of the plate-shaped body, including the portion, the edge surface having the circular arc cross section, and furthermore, the breaking strength of the plate-shaped body itself is further improved than the end face grinding and polishing process of a normal plate-shaped body. It is something.

On the other hand, in the molding of the present invention, injection molding methods such as RIM (reaction injection molding) method, R-RIM
(reinforced reaction injection molding) method, LIM (liquid injection molding)
The R-RIM method or the R-LIM method is particularly preferred.

The resins used in the above molding method include thermoplastic resins and thermosetting resins such as polyurethane, polyacetal, nylon 6, nylon 66, polyester, PBT, and epoxy.
Additionally, thermoplastic rubbers, such as polyolefins,
Polyurethane type, ethylene-vinyl acetate type, etc. are also used in some cases.

As the reinforcing material for the resin, general reinforcing materials such as inorganic fibers such as glass fibers and organic fibers such as aramid fibers are used.

The mold member during molding consists of two or more mold parts, and the mold member may have a plurality of injection ports so as to sufficiently cover the cavity space,
As the sealing material/buffer member, fluorine resin, silicone resin, silicone rubber, etc. can be used.

Various types of glass plates and synthetic resin plates are mainly used as plate-shaped bodies, including flat plates, bent plates, tempered glass, laminated glass, double-glazed glass, heat-reflective glass, various types of laminated glass, and as needed. Hard-coated acrylic boards, polycarbonate boards, etc., used in architecture, furniture, vehicles, automobiles, etc.

[Effect]

As mentioned above, the plate-shaped body with a holder member of the present invention has an arcuate cross-sectional edge surface with a bulge greater than the thickness of the plate-shaped body at a required location on the edge of the plate-shaped body, and a peripheral edge portion corresponding to the location. Since it is integrally molded surrounding both the front and back sides of the plate and directly fixed, the fixed area between the plate-shaped body and the holder member can be increased to some extent, and
By providing a snagging resistance effect, it has sufficient durability against the shearing force that acts on the fixed surface when moving the plate-like object, such as when moving it up and down, and it is far more durable than conventional ones that are simply glued. First, it is possible to integrate the plate-like object with a much stronger adhesion than when it is integrally molded as it is without processing, and it also eliminates the conventional bonding work between the plate-like object such as a glass plate and the holder member. Compared to conventional methods, the molding process is instantaneous, so there is no need to worry about curvature or other problems when attaching the holder member and the glass plate, etc., and the holder member can be formed and attached at the same time, reducing overall man-hours. Since it can be held more securely, it can be made lighter, smaller, and thinner than before, and can be used for vehicle or automobile window glass, architectural window glass and door glass, and furniture glass. It can be widely adopted for various uses such as doors.
