Description

  The present invention is mainly used as doors, sliding doors, etc. provided at entrances and entrances of houses, doorways, etc., openings of partition walls, etc. It is related to the joinery and its manufacturing method.

  Conventionally, as this type of joinery, a braided structure has been frequently used. In the frame structure, a vertical rod arranged on the right and left sides, an upper rod connecting the upper ends of the vertical rods, and a lower rod connecting the lower ends are joined in a rectangular frame shape, and the peripheral portion of the end plate is inserted therein. Skills are required for the work such as the processing of the details such as the joint between the scissors, the fitting part of the scissors and the end plate, and the assembly of each part. In addition, when the processing accuracy of these details is inferior, gaps or steps are generated between the ribs, which may deteriorate the appearance. Furthermore, since the basic construction of this type of joinery is almost determined, there is a limit to changing the appearance, and it has been difficult to respond to the diversification of needs for design in recent years. In addition, the braided construction fixtures are mainly made of solid wood, which increases the weight, requires a large hinge for the door, and has a large material expansion and contraction due to changes in humidity. In some cases, there were gaps between the heel and the side wall, between the heel and the end panel, and sometimes the entire joinery warped.

In order to solve such a problem of the frame structure, a frame is formed by having vertical frames on the left and right sides and combining square members vertically and horizontally between the vertical frames. There has been proposed a flash-structured joinery that is constructed by attaching a plurality of pieces to the surface in a state of being vertically butted (see, for example, Patent Document 1).
JP 2002-371758 A

  The flash structure joinery does not require high-precision processing as required in a braided structure, can be manufactured at a relatively low cost, and has various appearance variations by using various design-friendly face materials. Since it can be easily increased, it has become possible to meet diversified design needs. Further, the weight can be reduced and the dimensional expansion and contraction accompanying the change in humidity can be reduced, so that the generation of gaps and warpages accompanying the change in dimension can be suppressed.

  However, an error may occur in the outer dimension of the face material based on a cutting error or the like when processing the face material, and an attachment position error may occur during the face material attaching operation. Based on these errors, gaps are created between the face materials at the joints of the face materials that are abutted against the surface of the frame, and the frame surface, the inside of the panel, etc. are exposed from the gaps, and the appearance is impaired. There is. Moreover, since the face material is composed of a relatively thin plate, warping is likely to occur with changes in temperature and humidity. Even when the adjacent face materials are abutted on the frame and fixed to the frame, a step may be generated between the face materials due to the warp, and in this case, the appearance of the joinery is impaired. In the joinery having the flash structure, the face material functions as a stress skin material and bears the in-plane shear strength of the joinery. However, if there are gaps or steps in the face material, there is a problem that the function as a stress skin material is reduced and the deformation resistance strength of the joinery is lowered.

  An object of the present invention is to solve the problems of the conventional joinery described above, and to provide a joinery having improved design properties by preventing the occurrence of gaps and steps between the face materials and having high deformation resistance. That is.

  The invention according to claim 1 of the present application is a joinery comprising a vertical gutter arranged on the left and right sides, and an end plate panel in which a face material is attached to a core material, and the end face plate has an end face adjacent to the end plate panel.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a joinery 1 of the present invention, FIG. 2 is a partially broken perspective view thereof, and FIG. 3 is an enlarged perspective view of an essential part thereof. The joinery 1 of the present invention includes a vertical fence 2 and an end panel 5.

  As shown in FIGS. 1 and 2, the vertical rod 2 has a flat columnar shape and is arranged in line symmetry with a pair on the left and right. Each vertical rod 2 is a vertical surface attached to the vertical frame 21 and both surfaces thereof. The material 22 and 22 are comprised. The eaves frame 21 has a vertically long pair of eaves bars 21a and 21a, and is provided between the eaves frame 21a, and has an eaves core 21b having the same thickness as the eaves frame 21a. Auxiliary bars 21c are attached to the inner surface. As shown in FIG. 6, the collar members 22, 22 are arranged so as to protrude a small length from the surface of the auxiliary bar 21 c, thereby forming the receiving groove 10 extending in the vertical and full length on the inner surface of the vertical rod 2. Has been. Further, a vertical support groove 13 extending from the upper end to the lower end is formed at the groove bottom of the receiving groove 10 by cutting the approximate center of the surface of the auxiliary bar 21c. The crosspieces 21a and 21b use a single plate laminated material (LVL), particle board, and the like, and the auxiliary crosspieces 21c use a relatively hard wood material such as medium fiberboard (MDF) and modified wood.

  The surface material 22 is made of phenol, amino or urea on a plywood or other surface of a veneer sliced from about 0.2 to 0.6 mm of raw wood such as oak, cherry, teak, zelkova, tochi, sen and hippo. Using a veneer veneer bonded with an adhesive such as a system gives a natural texture. In addition to this, the face material 22 may be a hot-press molded melamine resin laminated decorative board obtained by hot-pressing a melamine resin-impregnated paper on a substrate, a painted decorative board coated with a polyester resin, a polyurethane resin, or the like on the substrate surface. it can. In addition, a side surface material 23 obtained by cutting a decorative plate of the same type into a strip shape is attached to the outer surface of the vertical surface 2 so that a decorative finish continuous with the surface material 22 is formed. Further, the upper and lower end surfaces of the vertical gutter 2 may be covered with the same type of decorative board.

  In this example, the end plate panel 5 includes a first end plate panel 5A disposed between the left and right vertical panels 2 and 2, and the left and right vertical panels 2 and 2 above the first end panel 5A. The second end plate panel 5B is arranged, and a small interval is provided between the first end plate panel 5 and the second end plate panel 5B.

  The first end panel 5A is composed of a core material 3 and a face material 4 attached to both surfaces of the core material 3 and arranged in a plurality of rows on both sides, and has a flash panel structure. ing. In the present example, the core material 3 is composed of rectangular bar-shaped vertical core materials 3a and 3a arranged on the left and right sides, and a horizontal core material 3b vertically spaced between the vertical core materials 3a. It constitutes a framework. The core material 3 is formed using a single plate laminated material (LVL), a particle board, or the like.

  The face material 4 has a rectangular shape, and a plurality of sheets, four in this example, are arranged on the surface of the core material 3 with no gaps in a state where the upper and lower end sides are butted. As shown in FIG. 3, a notch portion 7 having a small width is provided on the back surface of the face material 4 along the edge to be abutted. When the adjacent face materials 4 and 4 are brought into contact with each other, both of the cutout portions 7 are continuous, whereby a groove-shaped recess 9 is formed. A long thin plate-like backing plate 8 that is slightly narrower than the width of the concave portion 9 and has substantially the same thickness as the depth of the concave portion 9 is fitted into the concave portion 9, and at this time, the backing plate 8 and both face materials 4 The face materials 4 are bonded to each other through the backing plate 8 by adhering the notch portions 7 to form the face material joint portion 6. As described above, the face material joining portion 6 is a portion where the face materials 4 and 4 are joined by the notch portion 7 of the face material 4 and the backing plate 8. Since the face materials 4 and 4 are bonded and integrated with each other through the backing plate 8, it is possible to suppress the formation of gaps and steps between the face materials 4. It will not stand out and will not look bad. Furthermore, since the face material 4 bonded and integrated through the backing plate 8 functions as a stress skin, the deformation resistance strength of the joinery increases.

  Moreover, in this example, since the face material joint portion 6 of the first end panel 5A matches the position of the horizontal core material 3b of the core material 3, the face material 4 in the vicinity of the backing plate 8 and the notch portion 7 is used. By adhering to the horizontal core material 3b, the bonding strength between the face materials 4 increases, which is preferable in that the effect of preventing gaps and steps is enhanced. In addition, this invention is not limited to the position of the face material joining part 6 being in agreement with the position of the core material 3. Furthermore, since the backing plate 8 does not protrude from the back surface of the face material 4 when the backing plate 8 is formed to have a thickness equal to or smaller than the depth of the recess 9 as in this example, It is preferable in that the face material 4 does not warp even if the face material joint 6 is stacked on the core material 3.

  The face material 4 may be a veneer decorative board, a melamine resin laminated decorative board, a painted decorative board coated with a polyester resin, polyurethane resin, or the like on the surface of the board, and the same material as the face material 22 is used. Then, it is preferable at the point which can unify a material feeling. The backing plate 8 is made of a resin plate such as melamine resin, phenol resin, or polyester resin, or a metal plate such as stainless steel or aluminum. For example, if the backing plate 8 having the same surface finish as the face member 4 is used, such as using a melamine resin laminated decorative plate for the face member 4 and a melamine resin plate for the backing plate 8, Even if a gap occurs in the material 4, it becomes difficult to visually recognize the gap and the appearance is not impaired. However, when the backing plate 8 having the same finishing layer as the face material 4 is used on the surface of the substrate, the surface is directed to the outside which is the side facing the face material 4.

  The second end plate panel 5B is formed by adhering face materials 4 and 4 to both surfaces of a core material 3 which is a framework of left and right vertical core materials 3a and upper and lower horizontal core materials 3b. The same one as the first end panel 5A is used.

  In the fitting 1 of the present invention, a first end plate panel 5A and a second end plate panel 5B are arranged above the first end plate panel 5A with a small space between the left and right vertical fences 2 and 2. Configured. As shown in FIG. 7, the upper surface of the horizontal core member 3b positioned at the upper end of the first end plate panel 5A and the lower surface of the horizontal core member 3b positioned at the lower end of the second end plate panel 5B face each other. Auxiliary cores 3c, 3c having lateral support grooves 11 extending in the left-right direction are attached to the surface. As a result, a lateral support groove 11 is formed on the upper end surface of the first end panel 5A and the lower end surface of the first end panel 5A, and the upper and lower edges of the thin decorative sheet 12 are inserted by the lateral support groove 11. The thin sheet decorative material 12 can be easily attached without falling off and rattling. Further, since the thin decorative sheet 12 is arranged between the first and second end panel 5A, 5B, it functions as an accent on the design, can give a deep and profound feeling, and the design is enhanced. Further, as shown in FIG. 5, the left and right edge portions of the thin decorative sheet 12 are inserted and supported in the vertical support grooves 13 of the vertical rod 2, whereby the fixed state of the thin decorative sheet 12 is further stabilized. Moreover, since the said vertical support groove | channel 13 is formed ranging from the upper end to the lower end of the vertical gutter 2, by changing the structure of the 1st, 2nd end plate panels 5A and 5B, the said thin-plate decorative material 12 is made arbitrary. It can be placed at a height and design freedom is high. In addition to a transparent plate and a semi-transparent plate, the thin plate decorative material 12 may be configured in a lattice shape or a strip shape, and glass, plastic, metal, or the like is used. The auxiliary core material 3c is made of medium fiberboard (MDF), modified wood, or the like.

  As shown in FIGS. 2 and 4, the end plate panel 5 and the vertical gutter 2 are joined together by dowel pins 24 at a plurality of upper and lower portions, thereby being assembled as a joinery 1. Both ends of the dowel pin 24 are press-fitted into lower holes (not shown) having a slightly smaller diameter than the dowel pins 24 formed on the vertical core member 3a of the end plate panel 5, the auxiliary bar 21c of the vertical bar 2 and the bar bar 21a. The end plate panel 5 and the vertical gutter 2 are coupled by the frictional force.

  As shown in FIGS. 4 and 6, both side portions of the end panel 5 joined to the vertical rod 2 are fitted in the receiving grooves 10 formed on the inner surface of the vertical rod 2. Thereby, even if the vertical gutter 2 and the end panel 5 are deformed such as warping, no gap is generated and the appearance is not impaired. In addition, the integrity of the vertical fence 2 and the end panel 5 is increased, and the strength of the joinery 1 is increased.

  Next, the manufacturing method of the joinery 1 is demonstrated based on FIG. In the production process of the end plate panel 5, first, a narrow notch 7 is formed on the back surface of the face material 4 by cutting with a constant thickness using an electric cutting tool or the like along the edges to be joined together. Next, on the work table, a plurality of face materials 4 with the back side facing up are arranged with their end sides abutted, and in the recesses 9 formed by the notches 7, 7 of the adjacent face materials 4, 4. The backing plate 8 is fitted into. At this time, an adhesive such as a polyurethane adhesive, a urea resin adhesive, or a hot melt adhesive is applied between the cutout portion 7 and the backing plate 8 and pressed to apply the face material via the backing plate 8. 4 and 4 are bonded and integrated.

  Next, a plurality of face materials 4 bonded in a butted state are bonded to the core material 3 to create the end plate panel 5. In this example, as shown in FIG. 2, the core material 3 has a left and right vertical core material 3 a and a plurality of horizontal core materials 3 b framed in advance in a lattice shape. It is not limited.

  The vertical rod 2 is created by first forming the rod frame 21 by bonding a plurality of rod cores 21b between the left and right rod bars 21a, 21a and fixing them with nails, screws or the like. In this example, an auxiliary bar 21 c is further bonded to the inner side surface of the collar frame 21. Next, the face material 22 is bonded to both surfaces of the frame 21 and the side material 23 is bonded to the outer surface.

  Next, the joinery 1 is assembled by joining and integrating the vertical rod 2 and the end panel 5 via the dowel pin 24. As described above, since the face materials 4 that are abutted with each other are bonded together via the backing plate 8 disposed in the recess 9 formed by the notch portion 7 on the back edge of the face material 4, Generation of gaps and steps between the face materials 4 to be abutted against each other is suppressed, and the appearance is improved. Further, even if a small gap occurs, the backing plate 8 is closed, so that it does not stand out and the appearance is not impaired. Furthermore, since the face material is bonded and integrated through the backing plate 8 and functions as a stress skin, the strength is improved.
