Description

  The present invention relates to a structure and method for attaching a decorative molding to a surface to be decorated such as an outer wall surface of a building.

  In order to apply makeup to the outer wall surface of a building (improve the designability), an elongated decorative member (decorative molding) may be fixed to the outer wall surface in an appropriate arrangement. For example, an elongated decorative member (decorative molding) is arranged and fixed around the window frame and the door frame so as to surround them.

  In order to fix the above-mentioned makeup molding to the wall surface, conventionally, a makeup molding having a cross section of L-shape or U-shape has been used. Since the cross section has an open shape such as an L shape or a U shape (not a closed tubular shape in the cross section), the fixture fixed to the wall surface is inserted from the open location into the cosmetic molding and connected. (See FIG. 1 of Patent Document 1, for example).

  However, a cosmetic molding having an open cross section has the following problems. That is, when the decorative molding is composed of a "core material" and a "resin decorative layer fixed to its outer surface" and is manufactured by integral extrusion molding, the core material is deformed by the pressure of the resin during molding. However, there is a case where the originally designed shape (cross-sectional shape) cannot be obtained.

  Here, the integral extrusion molding is to extrude a core material and apply resin to the surface of the extruded core material to integrate them. The compact is then cooled and cut to size. Such integral extrusion molding itself is generally known, and is also described in Patent Document 2, for example.

  In order to realize a decorative molding that does not deform even if it is integrally extruded, it is conceivable that the decorative molding has a closed cross-sectional shape of a tubular shape. In the case of a tubular decorative molding, even if it is integrally extruded so as to have a resin layer around it, the shape of the core material itself is unlikely to change.

  However, how to attach such a tubular decorative molding to a wall surface or the like becomes a problem. With a mounting bracket that is simply connected to the outer surface of the cosmetic molding, or in a structure where the fixing screw is exposed on the outer surface, the mounting tool (mounting bracket, fixing screw, etc.) is visible from the outside, and the cosmetic molding is designed to improve the design. This is because the original function is impaired.

  In view of the above conventional circumstances, an object of the present invention is a mounting structure and method for mounting a decorative molding having a closed cross-sectional shape and hardly deformed during extrusion molding on a surface to be decorated, and also has a good appearance design. To provide a simple mounting structure and method.

Means for Solving the Problems and Effects of the Invention

In the mounting structure of the present invention, a tubular decorative molding having an outer ring having a tubular cross section and having an opening (first opening in the embodiment) on one side wall thereof is fixed to a surface to be coated via a fitting. The makeup molding attachment structure is attached to the surface to be decorated.
(1)
The fixture is
The main body fixed to the surface to be decorated,
A first elastic member and a second elastic member which are erected on the main body and elastically urged in directions away from each other;
A support step portion formed on the upper side of the main body portion and standing up in a direction away from the surface to be decorated. And
(2)
The first elastic member and the second elastic member enter the inside of the cosmetic molding through the opening and are pressed against the two side walls of the cosmetic molding facing each other from the inside.
The support step supports one side of the opening.

According to the above-mentioned mounting structure, first, since the decorative molding whose outer ring of the cross section is tubular is used, even if the decorative molding is made by integral extrusion molding, the decorative molding itself is deformed by the pressure of the resin. It's hard to happen. Therefore, it is possible to use a cosmetic molding having an originally designed shape, and the original purpose of the cosmetic molding to improve the external appearance design of a building or the like is not impaired.
Further, the fixture on the surface to be decorated enters into the interior of the makeup mall through an opening provided in one side wall of such a makeup mall, and the makeup mall is fixed to the surface to be makeup via this fixture. That is, since the fixture is located inside the tubular cosmetic mall, the fixture is not visually recognized from the outside, and in this sense also, the original purpose of the cosmetic mall is to improve the appearance design of buildings and the like. It is not damaged.

The first elastic member and the second elastic member included in the fixture are elastically biased in the directions away from each other, press the two side walls of the cosmetic molding that face each other inside the cosmetic molding, and face them outward. Press. Due to the pressing force and the reaction force, the decorative molding is fixed on the surface to be decorated.
In addition, the support step of the fixture supports one side of the opening, thereby stabilizing the posture (orientation) of the decorative molding on the surface to be decorated.

In the attachment structure of the present invention, the main body of the attachment may further include “a third elastic member that extends from the support step and is elastically biased in a direction toward the surface to be decorated”. preferable. The third elastic member is pressed against the side wall of the decorative molding provided with the opening and presses the side wall toward the surface to be decorated.
In the case of adopting such a configuration, it is possible to fix the decorative molding to the decorative surface with higher stability by the force of the third elastic member pressing the side wall of the decorative molding against the decorative surface.

In the present invention, the specific laminated structure of the decorative molding is not limited to a specific one, but the decorative molding is an integral extrusion molding including a metal core material and a resin layer provided on the outer surface thereof. It is preferably the body.
In this case, the effect of the present invention that the original shape of the decorative molding can be maintained becomes remarkable by forming the decorative molding into a tubular shape even if the resin pressure is applied during the integral extrusion molding.
Generally, when realizing a cylindrical shape with a single-layer structure using only resin, it is difficult to obtain high shape accuracy. Also in this sense, the use of a metal (aluminum or the like) core material is advantageous because the shape accuracy can be improved.

Further, according to the present invention, there is provided a method of attaching the cosmetic molding using the attachment. In the mounting method,
Process (1):
First, the decorative molding is pressed against the surface to be decorated so that the first elastic member and the second elastic member of the fixture on the surface to be coated enter into the opening, and the first elastic member and the second elastic member are held. The two opposing side walls of the decorative molding are pressed from the inside in a direction away from each other. Due to the pressing force and the reaction force, the decorative molding is fixed on the decorative surface.
Process (2):
In this state, the makeup molding is slid along the surface to be decorated, and one side of the opening is supported by the support step portion of the fixture. This stabilizes the posture (orientation) of the cosmetic molding on the surface to be coated.

  In the above mounting method, when the main body of the mounting tool to be used further includes “a third elastic member that extends from the support step and is elastically biased in a direction toward the decorative surface”, When the step (2) is finished, the third elastic member is pressed against the side wall of the decorative molding from the inside, and presses the side wall toward the decorative surface. By the pressing force, the decorative molding can be fixed to the surface to be decorated with higher stability.

The figure explaining the makeup | decoration molding 10 and attachment tool 20 used in the attachment structure which concerns on one Embodiment of this invention. The figure explaining the attachment method (procedure) of the cosmetic molding 10 via the attachment tool 20. The figure explaining the attachment method (procedure) of the cosmetic molding 10 via the attachment tool 20.

  An embodiment of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1B shows the fixture 20 fixed to the decorative surface S. The surface S to be decorated is a surface to which some kind of makeup is applied, such as an outer wall of a house. As will be described later, the makeup mall 10 is fixed to the decorative surface S via the fixture 20 fixed to the decorative surface S.

<Structure of fixture>
The fixture 20 is made of a metal plate member as a whole, and is provided with a main body 21 fixed to the surface S to be decorated by an appropriate means such as a screw 1, and a pair of (first , (Second) elastic members 22a and 22b are provided upright. The first elastic member 22a and the second elastic member 22b are elastically urged in directions away from each other, and by contacting the opposing side walls 12a, 12b of the cosmetic molding 10 from the inner surface side, as described later, The cosmetic molding 10 is stably held.
A support step portion 23 is provided on the upper portion of the main body portion 21. In FIG. 1, the support step portion is provided along an imaginary line A (FIG. 1b) connecting the first elastic member 22a and the second elastic member 22b. As shown in FIG. 1C, the support step portion 23 rises in a direction away from the surface S to be decorated. As will be described later, the support step portion 23 makes contact with one side 13 of the first opening 11 of the cosmetic molding 10 when the cosmetic molding 10 is fixed, thereby stabilizing the posture of the cosmetic molding 10.
The third elastic member 22c further extending from the support step portion 23 has a region 25 near the tip thereof curved toward the surface S to be decorated, and the curved region 25 elastically extends in the direction toward the surface S to be decorated. Being energized. As will be described later, the third elastic member 22c (the curved region 25 thereof) is pressed against the side wall 12c of the decorative molding 10 from the inner surface side, and presses the side wall 12c against the surface S to be decorated.
In the curved region 25 of the third elastic member 22c, a locking portion 25a formed by cutting and raising is formed. As will be described later, the locking portion 25a prevents the cosmetic molding 10 from coming off (sliding upward). It should be noted that, because the material of the fixture is required to be elastically biased, a stainless steel plate, a galvalume steel plate, or the like is used, but the material is not particularly limited.

<Structure of makeup mall>
As shown in FIG. 1 (a), the decorative molding 10 is a member whose cross-section outer ring is tubular and has a quadrangular cross section, and includes four side walls 12 a to 12 d. The first opening 11 is provided in one of the side walls 12c, and the elongated second opening 15 is formed adjacent to the first opening 11. The makeup mall 10 is attached / fixed to the decorative surface S via the fixture 20 fixed to the decorative surface S.

In the present invention, the decorative molding 10 is not limited to a specific configuration as long as the outer ring of the cross section has a tubular shape. In the illustrated example, the decorative molding 10 includes a metal core material 30 and a resin layer 31 on the outer surface thereof, and is manufactured by integral extrusion molding.
Since the outer shape of the decorative molding 10 is cylindrical, deformation is unlikely to occur even when pressure of the resin is applied during integral extrusion molding, and the originally intended shape can be favorably maintained.

<Example of material of the core material 30>
The core material 30 can be made of, for example, a metal such as aluminum or aluminum alloy, stainless steel, galvanized steel, copper, etc., and has a viewpoint of lightness required for a building member and easiness of processing into a hollow or irregular shape. Therefore, aluminum or aluminum alloy is preferable. For example, a hollow or solid core material made of aluminum or an aluminum alloy can be formed by extrusion molding of aluminum or an aluminum alloy.
In particular, an aluminum core material having a wall thickness of about 0.8 to 2.3 mm is used as a cosmetic molding, but a resin made of a thermoplastic resin on the surface of a thin aluminum core material of about 0.8 to 1.8 mm. When the decorative layer is integrally extruded, the tubular shape is particularly advantageous against deformation. In the case of a resin decorative layer containing wood powder in a thermoplastic resin, a separate adhesive layer is interposed in order to compensate for the decrease in adhesion between the aluminum core material and the resin decorative layer (surface coating layer) due to the addition of wood powder. Often, the resin pressure is further increased, but it is still effective in such a case.

<Example of material of the resin layer 31>
As the resin layer 31, a resin containing a base resin and wood powder can be used. By providing the resin layer 31 containing wood powder on the outer surface of the core material 30, a wood-like appearance can be obtained. A polyolefin resin or the like can be used as the base resin. The thickness of the resin layer is usually 0.1 to 5.0 mm. An adhesive layer may be interposed between the resin layer 31 and the core material 30.

<How to attach the cosmetic mall via the fixture>
Next, with reference to FIGS. 2 and 3, a method (procedure) for attaching the cosmetic molding 10 via the attachment 20 will be described. The fixture 20 is previously fixed to the surface S to be decorated by an appropriate means such as a screw 1.

Process (1):
FIG. 2A shows a cross section in the longitudinal direction of the decorative molding 10 together with the fixture 20 fixed to the surface S to be decorated. In FIG. 2A, when the makeup molding 10 is pressed in the direction of arrow 1 toward the surface S to be decorated, the first elastic member 22a and the second elastic member 22b of the fixture 20 move to the first makeup molding mall. Entering into the opening 11, the first elastic member 22a and the second elastic member 22b press the two opposing side walls 12a and 12b of the cosmetic molding 10 in the direction away from each other. The “direction of moving away” is the direction indicated by the arrows a and b in FIG. 1A, and is the direction orthogonal to the paper surface in FIGS. 2A and 2B. The pressing force and the reaction force effectively prevent wobbling on the decorative surface S of the decorative molding mall 10.
Finally, the entire fixture 20 passes through the first opening 11 and enters the cosmetic molding 10. FIG. 2B shows this state. In this way, since the fixture 20 is located inside the tubular makeup mall 10, the fixture is not visually recognized from the outside, and the original purpose of the makeup mall is to improve the appearance design of a building or the like. It is not damaged.

Process (2):
From the state of FIG. 2B, when the makeup molding 10 is slid downward along the makeup surface S as shown by the arrow 2, the side wall 12c of the makeup molding 10 (the area sandwiched between the openings 11 and 15). Pushes up the curved region 25 of the third elastic member 22c of the fixture 20. FIG. 3A shows this state. Since the third elastic member 22c is elastically urged in the direction toward the surface S to be decorated, the side wall 12c can be pressed against the surface S to be decorated, and thereby the makeup molding 10 can be stabilized.
When the makeup molding 10 is slid further downward from the state shown in FIG. 3A, the second opening 15 comes down to the position of the curved region 25 of the third elastic member 22c, The curved region 25 enters the second opening 15. At this time, the support step portion 23 of the fixture 20 contacts one side 13 (FIG. 1a) of the first opening 11, whereby the decorative molding mall 10 is held on the surface S to be decorated with a stable posture (direction). To be done. FIG. 3B shows this state and also shows a region near the support step portion 23 in a partially enlarged manner.
Further, the locking portion 25a formed in the curved region 25 is located so as to face one side 17 (see FIG. 1a) of the second opening 15 and thereby functions as a retaining member.

<Other Embodiments>
(1)
In the illustrated embodiment, the cosmetic molding 10 has a cross-section outer ring having a tubular shape and a rectangular cross section. This has the following meanings. That is, even if the cosmetic molding 10 is formed by integral extrusion molding, the cosmetic molding itself is unlikely to be deformed by the pressure of the resin, and the cosmetic molding can maintain the originally intended shape accurately. Therefore, the original purpose of the makeup mall, which is to improve the external appearance of buildings, is not impaired.
In other words, “the outer ring of the cross section is cylindrical” means that the cross section is not an open shape (L-shape, U-shape, etc.) but is closed, and there are undulations on the surface or protrusions. , The outer ring of the cross section corresponds to the tubular shape as long as the cross section is closed.
Further, as long as the outer ring is tubular, the decorative molding 10 does not have to be quadrangular, and may have a triangular shape, a semicircular shape, or any other cross-sectional shape. Further, a reinforcing partition plate or the like may be present inside the tubular shape.

(2)
Regarding the configuration of the attachment 20, the third elastic member 22c may be omitted. Even if the third elastic member 22c does not exist, the first and second elastic members 22a and 22b press and support the side walls of the decorative molding mall 10 in opposite directions (outward directions), and the upper part of the main body portion. To the side, specifically, since the support step portion 23 extending along the virtual line A (FIG. 1b) connecting the first and second elastic members 22a and 22b stabilizes the posture of the cosmetic molding 10, these The decorative molding 10 can be fixed to the surface S to be decorated with only the above elements.
However, it is preferable to further add the third elastic member 22c and press the side wall of the decorative molding toward the surface to be decorated to further increase the fixing strength.

(3)
In the illustrated embodiment, the fixture 20 is entirely made of a metal plate, and the elastic force (biasing force) of the first to third elastic members 22a, 22b, 22c is obtained by the elasticity of the metal. However, in the present invention, the specific configuration of the attachment is not limited to that shown in the figure as long as it provides the same biasing force in some form.

(4)
In the illustrated embodiment, an example in which a single fixture 20 is used to attach a relatively short makeup mall 10 is described, but the length of the makeup mall 10 is arbitrary, and if necessary, the makeup mall may be used. It is also possible to arrange a plurality of fixtures 20 in the longitudinal direction of and to fix the cosmetic molding through them. In addition, in the mounting step, the direction in which the cosmetic molding 10 is slid is not limited to the vertical direction, but can be set arbitrarily such as left, right, or diagonal.

(5)
As described above, since the fixture 20 is located inside the cosmetic mall 10 and is not visually recognized from the outside, it does not spoil the external appearance of the cosmetic mall 10. However, if necessary, the fixing strength may be increased by hitting a screw or the like from the outer surface of the decorative molding 10 to the internal fixture 20 at an inconspicuous position.
