DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin body with a mounting frame, and more particularly, to a resin body with a mounting frame that provides a novel structure for mounting the resin body to the mounting frame. The resin body with a mounting frame of the present invention can be suitably used for, for example, a resin panel or a resin partition.

[0002]

2. Description of the Related Art Conventionally, glass panels have been used for the purpose of partitioning an indoor space. As shown in FIG. 4, such a glass panel generally includes a mounting frame 80 having an opening 80a, and a glass plate 90 having an outer surface shape corresponding to the inner surface shape of the opening 80a and attached to the opening 80a.
And When the glass plate 90 is mounted on the mounting frame 80, a spacer 82 made of rubber or the like is interposed between the inner peripheral surface 81 a of the concave groove 81 of the mounting frame 80 and the outer peripheral surface 90 a of the glass plate 90. A seal member 83 made of resin or rubber is interposed between the front and back surfaces of the outer peripheral edge portion 90b and the opposing inner surface of the concave groove 81 facing the front and back surfaces.

According to such a mounting structure, the spacer 8
2, the glass plate 90 can be reliably attached to the mounting frame 80 by restricting the play of the glass plate 90 with respect to the mounting frame 80. The presence of the sealing member 83 allows the glass plate 90 and the mounting frame 80 to be airtight. Nature can be secured.

[0004]

By the way, glass is
Compared to plastics, they have the drawback of being heavy and fragile, and having a low degree of freedom in shape and color. For this reason, if a plastic plate is used instead of a glass plate, it is possible to provide a resin panel free of such defects.

However, the above-described mounting structure of the glass plate 90 and the mounting frame 80 has a problem that a large number of parts are required for ensuring airtightness and the like, and the mounting operation is troublesome and time-consuming. . Even if a plastic plate is used instead of the glass plate 90, such a problem similarly occurs. When a plastic plate is used instead of the glass plate 90, plastic generally has a higher coefficient of thermal expansion and lower rigidity than glass,
When the plastic plate or the mounting frame expands and contracts under the influence of an environmental change, problems such as distortion of the plastic plate and deterioration of airtightness are likely to occur.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and it is possible to ensure airtightness between a resin body and a mounting frame with an extremely simple structure, and to easily perform a mounting operation and to reduce environmental problems. It is a technical problem to be solved to provide a mounting structure of a resin body and a mounting frame capable of solving a problem such as distortion of the resin body due to an influence of a change.

[0007]

A resin body with a mounting frame according to the present invention for solving the above-mentioned problems comprises: a mounting frame having an opening;
A resin body with a mounting frame having an outer surface shape corresponding to the inner surface shape of the opening and having a resin body attached to the opening, wherein the outer surface of the resin body faces the inner surface of the opening. A gap is formed between the surfaces, and a recess is formed on at least one of the outer surface of the resin body and the inner surface of the opening to increase the gap of the gap, and the recess is interposed between the recess and the gap. The resin body and the mounting frame are fixed to each other by an adhesive having elasticity.

In the resin body with the mounting frame, a predetermined gap is formed between the opening of the mounting frame and the opposing surface of the resin body. The presence of this gap facilitates fitting of the resin body into the opening of the mounting frame, and after mounting,
Relative expansion or contraction of the resin body with respect to the mounting frame due to the influence of environmental changes (expansion or contraction of the resin body or expansion or contraction of the mounting frame; the same applies hereinafter) is allowed.

Then, an adhesive is interposed in this gap,
Since the adhesive has elasticity, the relative expansion or contraction of the resin body with respect to the mounting frame is absorbed by the elastic deformation of the adhesive. In addition, a concave portion is formed on at least one of the outer surface of the resin body and the inner surface of the opening, and the adhesive is also filled in the concave portion, so that the relative expansion or contraction of the resin body with respect to the mounting frame is suppressed. It is possible to secure an adhesive volume capable of exhibiting a sufficient elastic deformation amount to absorb.

Therefore, even if the resin body greatly expands with respect to the mounting frame or the mounting frame shrinks greatly with respect to the resin body due to a change in the environment, the resin body or the mounting frame is not affected. Since the deformation is allowed by the presence of the gap while being absorbed by the elastic deformation of the adhesive, the deformation of the resin body can be effectively prevented. Further, even when the resin body largely shrinks with respect to the mounting frame, or when the mounting frame greatly expands with respect to the resin body, the adhesive is broken or the adhesive is It does not peel off at the interface with the resin frame, and it is possible to reliably ensure the reliability and airtightness of the fixing between the resin body and the mounting frame.

In addition, a very simple structure in which a gap and a concave portion are provided between the resin body and the mounting frame and an adhesive is interposed between the gap and the concave portion to ensure airtightness and prevent distortion of the resin body. In addition, after the adhesive is applied to the concave portion of the resin body, the resin body is attached to the mounting frame by an extremely easy operation of fitting the resin body into the opening of the mounting frame.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The resin body with a mounting frame of the present invention
A mounting frame having an opening, a resin body having an outer surface shape corresponding to the inner surface shape of the opening and attached to the opening,
An elastic adhesive is provided between the resin body and the mounting frame, which is interposed in a concave portion and a gap to be described later.

The material of the mounting frame is not particularly limited, and may be made of metal or resin. Further, the type of the resin of the resin body is not particularly limited. The shape of the inner surface of the opening of the mounting frame and the shape of the outer surface of the resin body are not particularly limited, and may be, for example, an elliptical shape or a perfect circular shape in addition to a rectangular shape such as a rectangle or a square. Further, the present invention is not limited to a mode in which the entire outer peripheral surface of the resin body is covered with the mounting frame, but a part of the outer peripheral surface (opening) of the resin body is opened, and the outer peripheral surface of the resin body is covered with the mounting frame. There may be some missing parts.

[0014] A predetermined gap is formed between the outer surface of the resin body and the opposing surface of the inner surface of the opening. The gap of this gap is appropriately set within a range in which the relative expansion or contraction of the resin body with respect to the mounting frame due to an environmental change is allowed according to the difference in the coefficient of thermal expansion between the resin body and the mounting frame and the use environment. You. The allowable range varies depending on the opening size, the difference in the coefficient of thermal expansion between the resin body and the mounting frame, the use environment, and the like.For example, when the resin body is made of polycarbonate and the mounting frame is made of an aluminum sash and used indoors. Sets the above gap to 2
About 5 mm. If the gap is too large, the mounting stability of the resin body to the mounting frame via the adhesive may be reduced. On the other hand, if the gap is too small, the resin body expands relatively to the mounting frame or the mounting frame contracts relatively to the resin body. Therefore, there is a possibility that stress is generated in the resin body or the mounting frame and distortion occurs.

A recess is formed on at least one of the outer surface of the resin body and the inner surface of the opening to increase the gap. The recess is provided on one or both of the outer surface of the resin body and the inner surface of the mounting frame so as to extend continuously over the entire circumferential direction between the outer surface of the resin body and the opposing surface of the inner surface of the opening. Can be formed. When a concave portion is formed on the outer surface of the resin body, the concave portion can be formed simultaneously when the resin body is molded by injection molding or the like. The width and depth of the concave portion are such that the adhesive interposed in the concave portion and the gap has an adhesive volume capable of exhibiting a sufficient elastic deformation amount to absorb the expansion or contraction under the use environment. It is set appropriately within a range that can be secured. Such a range varies depending on the opening size, the difference in the coefficient of thermal expansion between the resin body and the mounting frame, the elastic modulus of the adhesive, the use environment, and the like.For example, polycarbonate is used for the resin body, aluminum sash is used for the mounting frame, and the adhesive is used. When using a urethane-based adhesive for indoors, the width of the concave portion is about 5 to 20 mm,
The depth can be about 3 to 8 mm. If the width or the depth of the concave portion is too large, the amount of the adhesive used becomes excessive more than necessary, which is disadvantageous in cost. On the other hand, if the width or depth of the concave portion is too small, the amount of elastic deformation in the adhesive becomes insufficient due to a decrease in the volume of the adhesive, and the expansion or contraction cannot be sufficiently absorbed by the elastic deformation of the adhesive. Problems such as distortion of the body or peeling of the adhesive are likely to occur.

The resin body and the mounting frame are fixed with an elastic adhesive interposed in the concave portion and the gap. Here, having elasticity means that when the resin body expands or contracts relatively to the mounting frame in the use environment, the resin body absorbs the expansion or contraction by elastic deformation of the adhesive. Is elastically deformable to such an extent that it can be effectively prevented from being distorted or the adhesive being ruptured and peeled off. Therefore, regarding the elasticity of the adhesive, it is necessary to absorb the expansion or contraction by the elastic deformation of the adhesive under the use environment, and effectively prevent the resin body from being distorted or the adhesive from being broken or peeled. Is appropriately set within a range in which is possible. Such a range varies depending on the difference in the coefficient of thermal expansion between the resin body and the mounting frame, the gap of the gap, the width and depth of the concave portion, the use environment, and the like.For example, a polycarbonate is used for the resin body, and an aluminum sash is used for the mounting frame. When used indoors, the dynamic viscoelasticity of the adhesive is 3 to 5 MPa.
(Room temperature). If the elastic modulus of the adhesive is too large, the amount of elastic deformation of the adhesive is insufficient, and the expansion or contraction of the adhesive cannot be sufficiently absorbed due to the elastic deformation of the adhesive. And other problems are likely to occur. On the other hand, if the elastic modulus of the adhesive is too small, the mounting stability of the resin body to the mounting frame via the adhesive may be reduced. The adhesive having the dynamic viscoelasticity in the above-mentioned predetermined range includes a polyurethane adhesive and a synthetic rubber adhesive.

In a preferred aspect of the resin body with a mounting frame according to the present invention, the resin body includes a window and an outer peripheral frame formed on the outer periphery of the window, and the window and the outer peripheral frame are provided. Can be integrally formed by two-color molding. The window and the outer peripheral frame may be transparent, translucent or opaque. The resin of the window portion and the resin of the outer peripheral frame portion may be of the same type or different types as long as they can be welded by two-color molding. If the window is made transparent or translucent, it can be suitably used as a resin panel or a resin partition. As a combination of the resin used for the window and the outer peripheral frame, for example, a transparent polycarbonate (PC) is used for the window and a colored polycarbonate (PC) is used for the outer peripheral frame, or a methacrylic resin (PMMA) is used for the window. In addition to using styrene resin (PS), the same resin can be used for the outer peripheral frame portion.

The size and outer shape of the window are not particularly limited, and may be, for example, a rectangle such as a rectangle or a square, an ellipse or a perfect circle. Further, the window portion can be formed in a flat plate shape or a curved plate shape. The outer peripheral frame may have an outer shape corresponding to the outer shape of the central plate. In the case where the resin body is composed of the window and the outer peripheral frame, the concave portion can be formed on the outer surface of the outer peripheral frame.

In a preferred aspect of the resin body with a mounting frame according to the present invention, the window portion includes a central plate portion formed integrally with the outer peripheral frame portion by two-color molding; And a resin film bonded to the surface. The resin film can be bonded to both or one of the front and back surfaces of the central plate portion.

On the outer surface of the resin film, a desired functional film such as a scratch-resistant film or an anti-fogging film can be formed, if necessary. In other words, when it is desired to increase the scratch resistance of the resin film, a hard coating agent such as an epoxy resin, an acrylic resin, or a silicon resin is coated on the outer surface of the resin film, and then cured by heat or ultraviolet rays. May be formed as a hard coat film. When it is desired to increase the anti-fogging property, a water-soluble resin-based coating agent may be coated and then cured by heat or ultraviolet rays to form an anti-fogging film.

Further, it is possible to apply a printing ink to the surface of the resin film to be joined to the central plate portion, if necessary. That is, an arbitrary pattern such as a ground glass shape can be added to the window by applying printing ink for the purpose of enhancing the decorativeness of the window. In addition, as a printing ink, a polyester resin, an acrylic resin, or the like can be used.

In the resin body having such a configuration, for example, the molten resin in the central plate portion is injected while the resin film is inserted into the mold, and the central plate portion is injection-molded. After forming the window joined by wearing,
Inject the molten resin in the outer peripheral frame and injection-mold the outer peripheral frame,
It can be manufactured by welding the central plate portion and the outer peripheral frame portion to each other to form an integrated two-color molded product.
