Description

The present invention relates to fittings.

In general, fittings installed at entrances and exits of rooms are made of wood-based materials. However, fittings made of wood-based materials have the problem of warping due to moisture absorption and desorption.

In recent years, the housing industry has been required to save energy, and the development of so-called high-performance housing, in which the airtightness and heat insulation of the building are improved, is underway. However, in a high-performance house, even if the gas concentration is suppressed to, for example, 1000 ppm or less by enhancing the ventilation, moisture is likely to be adsorbed by fittings in the air circulation path. Therefore, warping of fittings is a big problem even in high-performance houses. In particular, fittings with a height of about 2000 mm to 3000 mm, which are called high doors, tend to warp more.

Here, Patent Document 1 discloses a fitting for a sliding door that includes a wooden fitting main body having vertical grooves on two side surfaces located in front and behind in the sliding direction, and a ridge portion made of a metal material that fits into the vertical grooves. A fitting with a side edge forming member having a convex cross section is described. As described above, in the fittings of Patent Document 1, warpage is made difficult to occur by using the ridges made of a metal material as reinforcing materials for the fittings main body.

Japanese Patent Application Laid-Open No. 2008-202360

However, the fitting of Patent Document 1 requires two metal members extending in the vertical direction as reinforcing materials for suppressing warping of the fitting body, so it is difficult to reduce the weight of the fitting while suppressing warping as a whole.

The present invention has been made in view of the above points, and its object is to provide fittings that are made of wood-based materials and that are reduced in weight while suppressing warpage.

A fitting according to the present invention includes a frame formed of a wood-based material, face members provided on both sides of the frame in the door thickness direction, and side members provided on both sides of the frame in the door width direction . wherein the face member and the side member are made of a glass plate material having flexibility, and an airtight member is provided over the frame to block air from entering the frame. there is

According to the present invention, since the airtight material blocks the entry of air into the frame, adsorption of moisture to the frame is suppressed. In addition, since the glass plate materials of the face material and the side material are hardly permeable to moisture, the intrusion of moisture into the frame can be suppressed by the face material and the side material itself. Therefore, it is possible to suitably suppress the warp of the frame.

Here, if the face material is made of a wood-based material as in the conventional case, there is a problem that the face material is relatively thin and has a large area, so that it is likely to warp. Therefore, even if the warp of the frame body is suppressed, as a result of warping of the face material having a large area, the whole fitting will be warped.

In contrast, in the present invention, since the face material is made of a glass plate material, the face material itself can be prevented from warping due to moisture absorption or the like. Therefore, according to the present invention, warping of the frame body is suppressed and the face material itself does not warp, so warping of the fitting as a whole can be suitably suppressed.

Moreover, since the face material is made of a flexible glass plate material, the face material is less likely to be damaged even if shaking or bending stress is applied to the fitting, and the durability of the fitting can be enhanced.

Furthermore, in the present invention, there is no need to provide a reinforcing member made of a metal material for the purpose of suppressing warpage, unlike in the prior art. Therefore, it is possible to reduce the weight of the entire fitting while suppressing the warp of the fitting.

The face member and the side member may be fixed to the frame by the airtight member . Further , the surface of the frame on which the glass plate member is not provided may be covered with the airtight material.
You may further provide the decorative material provided in piles with the said glass plate material. Further, the airtight material may be an adhesive airtight tape or the like.

Advantageous Effects of Invention According to the present invention, it is possible to provide fittings made of a wood-based material that are light in weight while suppressing warpage.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail based on the drawings. In addition, the present invention is not limited to the following embodiments.
<<Embodiment 1>>

FIG. 1 is a perspective view showing a fitting 1 in Embodiment 1. FIG. FIG. 2 is a front view showing the frame 10 of the fitting 1. FIG. FIG. 3 is a front view showing the frame 10 in which the face member 20 and the side member 22 are fixed by the airtight member 24. As shown in FIG. FIG. 4 is a front view showing the fitting 1. FIG. 5 shows an enlarged part of FIG. 3, and FIG. 6 shows an enlarged part of FIG. FIG. 7 shows a partially enlarged cross section taken along the line VII-VII in FIG.

In Embodiment 1, a fitting 1 applied to a sliding door will be described. The fitting 1 according to the present invention is not limited to a sliding door, and can be applied to a sliding door other than a sliding door, such as a hanging door, a single sliding door, a double sliding door, or a sliding door. can be applied.

As shown in FIG. 1, the fitting 1 is, for example, a top-hanging sliding door, and can slide left and right along an upper rail (not shown). The fitting 1 is pulled into the door pocket 5 from the closed state shown in FIG.

As shown in FIGS. 1 to 7, the fitting 1 includes a frame 10 made of a wood-based material and face members 20 provided on both sides of the frame 10 in the door thickness direction A. As shown in FIGS. The fitting 1 further includes side members 22 provided on both sides of the frame 10 in the door width direction B. As shown in FIG.

The wood-based material forming the frame 10 is mainly made of wood or a wood-derived material. Wood-based materials include solid wood, laminated wood, plywood, LVL (laminated veneer lumber), MDF (medium density fiberboard), particle board, and the like.

As shown in FIG. 2, the frame body 10 is formed in a rectangular frame shape as a whole. and a side frame member 13 arranged in the . Further, the frame 10 includes two middle frame members 14 extending in the door width direction B in the vertical central region of the frame 10, and vertical frame members 15 extending vertically in the central region in the door width direction B of the frame 10. It has

The upper frame member 11, the lower frame member 12, the side frame member 13, the middle frame member 14 and the vertical frame member 15 are all rectangular members made of wood-based materials. The middle frame member 14 and vertical frame member 15 are reinforcing members.

The face member 20 and the side member 22 are made of a flexible glass plate material. Here, the glass plate material having flexibility is formed of a thin glass material, and has flexibility that does not break even when bent to about 90 degrees. As this type of glass material, it is possible to use, for example, a glass material in which a compressive stress layer is formed on the glass surface by chemical strengthening.
The surface material 20 has substantially the same size as the front surface (rear surface) of the frame 10 . On the other hand, the side members 22 have substantially the same size as the side surfaces 10c on both sides of the frame 10 in the door width direction B. As shown in FIG.

As shown in FIGS. 3 , 5 and 7 , the fitting 1 further includes an airtight member 24 provided over the frame to block air from entering the frame 10 . The airtight material 24 is impermeable to moisture (air containing moisture). The face member 20 and the side member 22 are fixed to the frame 10 with an airtight member 24 .
The face member 20 and the side member 22 may be fixed by a fixing means other than the airtight member 24, such as an adhesive.

For the airtight material 24, for example, an adhesive airtight tape can be used. In addition to the airtight tape, other airtight materials such as an airtight agent that exhibits airtightness when hardened may be used.

The face material 20 is fixed by an airtight material 24 while being aligned with the front or back surface of the frame 10 . Moreover, the side member 22 is fixed by an airtight member 24 in a state of being aligned with the side surface 10 c of the frame 10 . The airtight material 24 in Embodiment 1 is provided along the outer edge of the face member 20 and the outer edge of the side member 22 . As a result, the space between the face member 20 and the side member 22 is closed by the airtight member 24 .

Here, as shown in FIG. 7, the upper surface 10a and the lower surface 10b of the frame 10 are not provided with glass plate members such as the face member 20 and the side member 22. As shown in FIG. The surface of the frame 10 exposed from this glass plate is covered with an airtight material 24 . Moisture absorption to the frame 10 is thereby suppressed.

At the upper end portion of the fitting 1 , an airtight material 24 closes the space between the upper surface 10 a of the frame 10 and the face member 20 and the side member 22 . Also, at the lower end portion of the fitting 1 , an airtight material 24 closes the space between the lower surface 10 b of the frame 10 and the face member 20 and the side face member 22 . Thus, the face member 20 and the side member 22 are airtightly fixed to the frame 10 . In addition, a heat insulating material (not shown) such as polyurethane foam is provided inside the fittings 1 .

As shown in FIGS. 4, 6 and 7, the fitting 1 further includes a decorative film 30 which is a decorative material 30 provided over the glass plate materials of the face material 20 and the side material 22 .

The decorative film 30 is made of a resin film that can be colored or printed. As a result, it is possible to uniquely form a desired color pattern on the appearance of fittings. Furthermore, the decorative film 30 has a function of reinforcing the glass plate materials of the face member 20 and the side member 22 . Also, in the unlikely event that the glass plate is broken, the glass can be prevented from scattering. The decorative material 30 is not limited to a film-like material, and may be, for example, a decorative sheet or decorative paper.

The decorative film 30 in Embodiment 1 is attached to the entire surface of the face member 20 and the entire surface of the side member 22 . The decorative film 30 may be a single-sided adhesive film material. Also, the decorative film 30 overlaps the airtight material 24 in the door thickness direction A. As shown in FIG.

The fitting 1 includes mohair 19 provided on the lower surface 10 b side of the frame 10 . The mohair 19 is a member for removing dust and has relatively soft brush-like bristles. The bristles of this mohair 19 are slanted so that the tips of the bristles are directed toward the door. As a result, even if the fitting 1 is for a sliding door, the inside of the door pocket 5 can be cleaned appropriately.

As described above, according to the first embodiment, air is blocked from entering the frame 10 by the airtight material 24 , so adsorption of moisture to the frame 10 can be suppressed. Moreover, since the glass plate materials of the face member 20 and the side members 22 are hardly permeable to moisture, the penetration of moisture into the frame 10 can be suppressed by the face members 20 and the side members 22 themselves. Therefore, warping of the frame 10 can be suitably suppressed.

Here, if the face member 20 is made of a wood-based material as in the conventional art, the face member 20 is relatively thin and has a large area, so there is a problem that the face member 20 is likely to warp. Therefore, even if the warp of the frame body 10 is suppressed, as a result of warping of the face material 20 having a large area, the whole fitting will be warped.

In contrast, in Embodiment 1, since the face material 20 is made of a glass plate, the face material 20 itself can be prevented from warping due to moisture absorption or the like. Therefore, in the fitting 1 of Embodiment 1, warping of the frame body 10 is suppressed and the face material 20 itself does not warp, so warping of the fitting 1 as a whole can be suitably suppressed.

Here, since the house is constantly shaken, if a glass plate material with high hardness is used for the face material 20, it may not be able to withstand the shake and may lead to breakage. On the other hand, in the first embodiment, since the face material 20 is made of a glass plate material having flexibility, the face material 20 is less likely to be damaged even if the fitting 1 is shaken or subjected to bending stress, and the durability of the fitting 1 is improved. can enhance sexuality.

Furthermore, in Embodiment 1, there is no need to provide a reinforcing member made of a metal material for the purpose of suppressing warpage, unlike the conventional case. Therefore, it is possible to reduce the weight of the fitting 1 as a whole while suppressing warping of the fitting 1 . Further, since the flexible glass plate material used for the face member 20 and the side member 22 is thin and light, the weight of the fitting 1 can be further reduced.

In general, the standard thickness of fittings is 27 mm, but the fittings 1 of the first embodiment can be thinned to, for example, about 15.4 mm. The fitting 1 of Embodiment 1 is also suitable as a fitting 1 for an automatic door, and it is possible to reduce the price by reducing the weight. When the fitting 1 of Embodiment 1 is used for an automatic door, the door can be opened with a light force in the event of a power failure, which is excellent in terms of safety. Furthermore, due to the properties of glass, the face material 20 is preferable because it allows radio waves and the like to pass through.

In addition, since the face member 20 and the side member 22 are fixed to the frame 10 by the airtight material 24, the work of sealing the frame 10 by the airtight material 24 and the face material by the airtight material 24 are required when the fitting 1 is manufactured. The work of fixing 20 and side member 22 can be performed in the same process, and it is also possible to improve workability during manufacturing.
Moreover, many of the constituent members used for the fittings 1 are reusable, and the components other than the decorative film 30 can be reused after being collected.

As described above, the fitting 1 of the first embodiment fundamentally changes the concept of general fittings, and even if the external shape is similar, it is completely different from the conventional fittings. .
<<Embodiment 2>>

8 to 10 show fittings 1 of the second embodiment. FIG. 8 is a partially enlarged view corresponding to FIG. 5 showing the frame 10 to which the face member 20 and the side member 22 are fixed via the airtight member 24, and FIG. It is the FIG. 6 equivalent view which expands and shows a part of fittings 1. FIG. FIG. 10 is a view equivalent to FIG. 7 showing a partially enlarged longitudinal section of the fitting 1. FIG.

The second embodiment differs from the first embodiment in the method of fixing the face member 20 and the side member 22 with the airtight material 24 . In addition, in the second embodiment, the same reference numerals are given to the same parts as in the first embodiment, and the description thereof will be omitted.

As shown in FIGS. 8 and 10, the face member 20 and the side member 22 in the second embodiment are made of a flexible glass plate material and fixed to the frame 10 via an airtight member 24. . For example, a non-hygroscopic adhesive is interposed between the front surface (rear surface) of the frame 10 and the face material 20 as the first airtight material 24a, and these are adhered to each other. As a result, the face material 20 is fixed to the frame 10 .

Similarly, a non-hygroscopic adhesive as the first airtight material 24a is interposed between the side surface 10c of the frame 10 and the side surface member 22, and these are bonded together. The side member 22 is thereby fixed to the frame 10 . The first airtight member 24 a is provided on the front (rear) surfaces of at least the upper frame member 11 , the lower frame member 12 and the side frame members 13 that constitute the four sides of the frame 10 . The first airtight material 24a may be provided on the entire front surface (rear surface) of each of the frame members 11 to 15 that constitute the frame 10. As shown in FIG.
The first airtight material 24a is not limited to the adhesive, and it is also possible to use, for example, a double-sided adhesive airtight tape.

The upper surface 10a and the lower surface 10b of the frame 10 are not provided with a flexible glass plate material, but are covered with a second airtight material 24b. This suppresses moisture absorption to the frame 10 on the upper surface 10a and the lower surface 10b. The second airtight material 24b is, for example, a single-sided adhesive airtight tape.

As shown in FIGS. 9 and 10, the face member 20 and the side member 22 are overlaid with a decorative film 30 . The decorative film 30 is attached to the entire surface of the face member 20 and the entire surface of the side member 22 .

As described above, in the fitting 1 of the second embodiment, as in the first embodiment, the airtight material 24 and the face material 20 can suppress adsorption of moisture to the frame 10, so warping of the frame 10 can be suppressed. be. In addition to that, since the face material 20 is formed of a glass plate material, the face material 20 itself does not warp. Therefore, the warping of the fitting 1 as a whole can be suitably suppressed.

Furthermore, since the face material 20 is made of a flexible glass plate material, the durability against shaking of the building can be enhanced, and the weight of the fitting 1 as a whole can be reduced.
