Description

The present invention relates to an upper frame for a sliding door and a manufacturing method thereof.

The upper part of the upper frame body made of a wooden substrate is formed with protrusions projecting downward at both ends in the prospective direction, and a groove is provided between the protrusions so that the entire upper frame for the sliding door is formed in a substantially U-shaped cross section. It is publicly known and is shown in Patent Documents 1 and 2 and the like. An upper rail that accommodates one or more sliding doors in an openable and closable manner is fitted in the concave groove. The upper frame (Kamoi material 1) shown in FIGS. 1 to 7 and FIGS. 9 and 10 of Patent Document 1 is formed with a single upper rail receiving groove 6 for a sliding door, and FIG. Two upper rail receiving grooves 6 and 6 are formed for the sliding door.

However, in the relationship between the depth dimension of the opening and the width dimension of the sliding door upper end rail, if the groove width becomes relatively large with respect to the expected dimension of the upper frame, FIG. 4, FIG. 6 and FIG. As described above, there is a problem that the expected size of the protruding portion at one or both ends in the width direction of the upper frame is reduced, and the protruding portion is damaged or broken at the time of attaching or constructing the decorative material. In particular, when the upper frame main body is formed of MDF, generally, the pressure surface at the time of MDF production is used so that the upper and lower frames are the upper and lower surfaces (flat use), and the left and right vertical frames are the inner and outer surfaces. (Vertical use), the upper frame body is in a state in which a plurality of fiber layers crushed by pressure are stacked in the vertical direction and is resistant to vertical impact from above, but horizontal from the side The above problem has become apparent because it is weak to the impact of the direction.

As described in Patent Document 2, V-cut processing is performed on a predetermined portion of one surface of a single plate material to form a plurality of bent groove portions, and the bent frame portions are bent to form an upper frame (paragraph 0030). ˜0039, FIG. 2), the projecting portion can be given high strength, but if the processing accuracy during V-cut processing is low, the desired shape (FIG. 2 (a)) cannot be obtained, Stable production is difficult.

Even if it is an upper frame body made of MDF, if the MDF is used vertically, it is possible to solve to some extent the problem that the protruding portion is damaged or broken when an impact is applied to the found surface. In order to use the MDF vertically, it is necessary to manufacture an MDF having a thickness larger than the expected size of the upper frame body, which is actually difficult. Vertically used in a state where multiple MDFs with a thickness that can be manufactured are stacked, or vertically used only at both ends located on the surface to be found, and joined to a flat-use MDF at the center. Although it is conceivable to use a frame main body, it is not realistic because it takes time and effort for manufacturing and increases costs.

Therefore, the problem to be solved by the present invention is to give the protruding portion of the upper frame for sliding doors a strength that does not break or break even when a decorative material is attached or applied. Another object of the present invention is to provide a sliding door upper frame that is less likely to be scratched on the surface stably and at low cost.

In order to solve the above-mentioned problem, the present invention according to claim 1 is characterized in that protrusions protruding downward are formed at both ends in the expected direction of the upper frame body made of a wooden substrate, and a concave groove is provided between these protrusions. The entire upper frame for sliding doors having a substantially U-shaped cross-section, and a reinforcing material is provided along the longitudinal direction on at least one finding surface of the upper frame main body, and at least the reinforcing material is adhered. A decorative sheet is continuously adhered to a region including the surface of the finding surface.

According to a third aspect of the present invention, in the upper frame for sliding doors according to the first or second aspect, the decorative sheet is a part of the upper surface of the upper frame body, and the lower surface of the projecting surface and the protrusion surface on which the reinforcing material is adhered. And it is stuck so that an inner surface may be covered and it may reach a part of lower surface of an upper frame main body.

The present invention according to claim 4 is the first step of sticking the resin-impregnated paper on both finding surfaces of the upper frame main body, and cutting the lower part of the upper frame main body to form the protrusions at both ends in the expected direction. A second step of forming a concave groove between these protrusions, and a second step of continuously adhering a decorative sheet to a region including at least a resin-impregnated paper-attached surface on both of the surfaces of the upper frame body. A process for producing an upper frame for sliding doors.

The present invention according to claim 5 includes a first step of cutting the lower part of the upper frame main body to form protrusions at both ends in the expected direction and forming concave grooves between the protrusions, and both sides of the upper frame main body. A second step of adhering the resin-impregnated paper to the attachment surface, and a third step of successively adhering the decorative sheet to the region including at least the surface of the resin-impregnated paper on the both sides of the upper frame body The manufacturing method of the upper frame for sliding doors characterized by the above-mentioned.

According to a sixth aspect of the present invention, in the third step of the manufacturing method of the upper frame for sliding doors according to the fourth or fifth aspect, a finding surface on which a reinforcing material is adhered from a part of the upper surface of the upper frame main body and Covering the lower surface and the inner surface of the protrusion, and further sticking a decorative sheet until reaching a part of the lower surface of the upper frame body.

According to the first aspect of the present invention, since the reinforcing material is provided on the finding surface of the upper frame body, even if an impact is applied to the expecting surface when the decorative sheet is attached or during construction, it is difficult to be damaged. In addition, even if the expected size of the protruding portion is formed small, the protruding portion is reinforced by the reinforcing material, so that the protruding portion can be effectively prevented from being broken or broken. Furthermore, since the decorative sheet is continuously adhered to a region including at least the surface of the finding surface to which the reinforcing material is adhered, the effect of preventing breakage or breakage of the protruding portion is further increased.

In addition, since the reinforcing material is covered with the decorative sheet and is not exposed, it does not impair the appearance regardless of the material, and it is not necessary to prepare a member that matches the color of the decorative sheet. Can be suppressed.

According to the second aspect of the present invention, since the reinforcing material made of resin-impregnated paper that is not easily deformed due to temperature changes and is lightweight is provided on the prospective surface, in addition to the above effects, deformation due to temperature changes is suppressed. As a result, it is possible to prevent deterioration over time and to easily perform construction work and the like.

According to the third aspect of the present invention, the decorative sheet covers, from a part of the upper surface of the upper frame body, the finding surface on which the reinforcing material is adhered and the lower surface and the inner surface of the protruding portion, and the lower surface of the upper frame body. Therefore, the effect of preventing breakage or breakage of the protruding portion can be exhibited more remarkably.

According to the fourth or fifth aspect of the present invention, a suitable method for manufacturing an upper frame for sliding doors is provided. In any of the manufacturing methods, when the decorative material is applied, the surface of the upper frame body is already covered with the reinforcing material, and the protruding portion is reinforced thereby. In this case, even if pressure or impact is applied to the finding surface, the upper frame for the sliding door can be manufactured in which the protruding portion is not easily damaged or broken.

According to the sixth aspect of the present invention, a part of the lower surface of the upper frame main body is covered from a part of the upper surface of the upper frame main body, covering the finding surface to which the reinforcing material is adhered and the lower surface and the inner surface of the protruding portion. Since the decorative sheet is stuck and wound so as to reach the upper end of the sliding door, it is possible to manufacture a sliding door upper frame that is less prone to breakage or breakage of the protruding portion.

Hereinafter, the present invention will be described in detail with reference to examples. 1 to 6, one or corresponding members or elements are denoted by the same reference numerals.

An upper frame (hereinafter simply referred to as “upper frame”) 10 according to an embodiment (Example 1) of the present invention is shown in FIG. The upper frame 10 is formed with projecting portions 12 and 12 projecting downward at both ends of the upper frame body 11 in the expected direction, and an upper rail fitting portion 13 (concave groove) is provided between the projecting portions 12 and 12. The whole is formed in a substantially U-shaped cross section. The sliding door upper frame 10 is used for a sliding sliding door. As shown in FIG. 4, an upper rail 20 having a projecting piece 21 projecting downward in the center of the prospecting direction is fitted into the projecting piece 21. The upper end of the sliding door (not shown) is accommodated in each of the recesses 22 and 22 partitioned by, and cooperates with a sill rail (not shown) fixed to the floor surface to support the lower end of the sliding door. The sliding door can be opened and closed freely.

The upper frame body 11 is made of a wood substrate such as a wood fiber board such as MDF or hardboard, plywood, LVL, solid wood, laminated wood, or a composite board thereof, but has excellent surface smoothness and is capable of cutting. Since it is easy, MDF is used suitably. In this embodiment, the upper frame body 1 is formed by using one MDF so that the pressing surface at the time of manufacture is the upper and lower surfaces of the upper frame 10 (flat use).

Chamfers 16 and 16 are obliquely formed on the lower ends of the two facing surfaces of the upper frame body 11. Although this is not necessarily an essential configuration, it is preferable in order to maintain the designability by making the crushing of the protrusions 12 and 12 inconspicuous, such as when the tips of the protrusions 12 and 12 come into contact with the outside. Although not necessarily clear from FIG. 1, in this embodiment, the upper end of the finding surface of the upper frame main body 11 is also chamfered in an arc shape (not indicated).

As an example, the dimensions of each part of the upper frame 10 according to this embodiment (including the reinforcing members 14 and 14 and the decorative sheets 15 and 15) are such that the upper frame body 11 has an expected dimension of 85 mm, an estimated dimension of 1591 mm, and a thickness. The length dimension is 30.4 mm, and each projecting portion 12 has a downward projecting dimension of 14.5 mm from the root portion and an expected dimension (width) of 5 mm.

Reinforcing materials 14 and 14 are attached to the finding surface (both side surfaces) of the upper frame body 11 up to the lower ends of the projecting portions 12 and 12. The reinforcing members 14 and 14 prevent the protrusions 12 and 12 from being damaged or broken when an impact is applied to the finding surface, and also prevents the finding surface from being damaged. For this reason, resin molded plates and metal plates can be used as long as they are harder and more rigid than wooden substrates, regardless of the material, but they are less susceptible to deformation due to temperature changes and are relatively lightweight. Resin-impregnated paper is preferably used because it is easy to handle. As the resin-impregnated paper, for example, a paper obtained by impregnating or applying phenol resin, melamine resin, acrylic resin, dup resin, or the like can be used.

Further, a part of the upper frame main body upper surface 11 a covers the finding surface on which the reinforcing members 14, 14 are adhered, the lower surfaces and inner surfaces of the projecting portions 12, 12, and further covers the upper rail fitting portion 13. The decorative sheets 15 and 15 are continuously attached to a part of the lower surface 11b of the upper frame main body that faces.

An example of the manufacturing process of the upper frame 10 is shown in FIG. First, a wood base material (MDF) 11 ′ to be the upper frame body 11 is prepared (FIG. 2A). The wood base material 11 ′ is prepared as having a size (84.6 mm) × expected size (1591 mm) × thickness size (30 mm) of the upper frame body 11 of the upper frame 10 as a final product. Use for normal use.

Reinforcing materials 14 are attached to the surface of the wooden substrate 11 '(FIG. 2B).

Next, the lower portion of the wood substrate 11 ′ is cut by a cutting machine (molder) to form the upper rail fitting portion 13, and the chamfers 16, 16 and the like are formed outside the lower ends of the protruding portions 12, 12. Then, the upper frame body 11 having a predetermined shape is obtained (FIG. 2C).

After this cutting process, a part of the upper surface 11a of the upper frame body covers the entire surface of the upper surface 11a to which the reinforcing members 14 and 14 are adhered, the lower surfaces and the inner surfaces of the protrusions 12 and 12, and the upper rail fitting. The decorative sheets 15 and 15 are continuously pasted over a part of the lower surface 11b of the upper frame main body facing the portion 13 (FIG. 2D). Thereby, the upper frame 10 of FIG. 1 is obtained, and the upper rail 20 is fitted to the upper rail fitting portion 13 so as to be used for actual use as shown in FIG.

In the manufacturing process described above, the reinforcing material sticking step (b) and the cutting step (c) may be performed in a reversed order. That is, in this case, as shown in FIG. 3, the manufacture of the upper frame 10 includes a wooden base material preparation step (a), a cutting step (b), a reinforcing material sticking step (c), and a decorative sheet sticking step ( It is carried out in the order of d). Each step is the same as described above with reference to FIG.

In the upper frame 10 obtained in this manner, the locating surface of the wood base material (MDF) 11 ′ that becomes the upper frame main body 11 is covered and reinforced with the reinforcing members 14 and 14, so The strength of 12 goes up. Therefore, even if it is the protrusion parts 12 and 12 with a small expected dimension, it is prevented or greatly suppressed that it breaks or breaks by the impact applied to the finding surface at the time of sticking a decorative sheet or construction. Moreover, since it becomes difficult to get a damage | wound on a found surface, the beauty | look by the decorative sheets 15 and 15 can be maintained over a long term.

An upper frame 10 according to another embodiment (Example 2) of the present invention is shown in FIG. The upper frame 10 is different from the upper frame 10 of the first embodiment in that a laminated board of two MDFs is used as a wooden substrate that becomes the upper frame main body 11. Since this difference is the same as the upper frame 10 of the first embodiment, the description thereof is omitted.

An upper frame 10 according to another embodiment (Example 3) of the present invention is shown in FIG. In the upper frame 10, an upper rail fitting portion 13 for one sliding door is formed on one end side in the prospective direction of the upper frame main body 11 for a single sliding door, and the protruding portion 12a on one end side is the first embodiment. The projection 12b on the other end side is different from the upper frame 10 of the first embodiment in that the projection 12b on the other end side has a large expected size. Since this difference is the same as the upper frame 10 of the first embodiment, the description thereof is omitted. The present invention can also be implemented as an upper frame used for such a sliding door.

In this embodiment, the reinforcing members 14a and 14b are pasted so as to cover both the finding surfaces of the projecting portions 12a and 12b. However, the projecting portion 12b having a large expected size may be subjected to an impact. Since the possibility of breakage or breakage is relatively small, the reinforcing material 14a may be attached only to the expected surface of the protruding portion 12a having a small expected size, and the reinforcing time 14b may be omitted.

Although the present invention has been described in detail with reference to some embodiments, the present invention is not limited to these embodiments and is within the scope of the invention defined based on the description of the scope of claims. Various modifications or changes can be made. As will be apparent to those skilled in the art, the present invention is not limited to the sliding and single sliding doors described as examples, but can also be implemented as an upper frame for three or more sliding doors.
