Description

  The present invention relates to an improvement of a flash door in which a surface plate is fixed to a frame material.

  The flash door is manufactured by fixing a surface plate on both sides of a frame material. In the door of this structure, the outer periphery of the surface plate is fixed to a door frame made of a frame material composed of a vertical frame and a horizontal frame, and an opening is provided in the surface plate, and a decorative plate is fixed here. This door is provided with a frame of a frame material fixed along the opening, and a surface plate is fixed to both sides of the frame. The flush door with this structure requires a high degree of processing accuracy and labor in order to cleanly finish the part that fixes the surface plate to the door frame and frame.

  A door for fixing a decorative plate such as glass to an opening window provided on the surface plate through a frame has a structure shown in FIGS. 1 to 3 and fixes the decorative plate 24. The door shown in FIG. 1 has a frame 23 bonded to a core member 25 fixed along the opening window 22 of the surface plate 21. The frame 23 is finished in the same plane as the surface plate 21 fixed to the core member 25. As shown in FIG. 1, a door in which the frame 23 does not protrude from the surface plate 21 can be used as a sliding door with a clean design. This is because the frame 23 does not collide with another door when the sliding door is opened. In this door, the corners of the frame 23 are chamfered and a V-groove 26 is provided between the frame 23 and the surface plate 21 in order to finely finish the boundary between the surface plate 21 and the frame 23.

  In the door shown in FIG. 2, the core member 25 protrudes from the edge of the surface plate 21 into the opening. This door has a frame 23 fixed to the protruding portion of the core member 25. The frame 23 is provided with a U-shaped U-shaped groove 27 on the outer surface in order to fit the core material 25. The door of this structure can also make the frame 23 and the surface plate 21 into the same plane. Therefore, it can be used for sliding doors.

  Further, the door shown in FIG. 3 fixes the frame 23 in a state where the surface plate 21 fixed to the core member 25 is sandwiched. The frame 23 is provided with a U-shaped groove 27 on the outer surface in order to sandwich the surface plate 21 fixed on both surfaces of the core member 25. In the door of this structure, since the frame 23 protrudes from the surface plate 21, it is necessary to widen the distance between the two doors in order to use the sliding door. However, if the distance between the two doors is wide, there is a problem that a draft is likely to pass between the doors.

  The door shown in FIG. 1 has the feature that the frame 23 and the surface plate 21 can be coplanar. However, it is extremely difficult to finish the border between the frame 23 and the surface plate 21 cleanly. This is because it is difficult to finish the gap between the frame 23 and the surface plate 21 at a constant interval and finish with high accuracy, and an irregular gap is formed between them. It is difficult to process the inner edge of the opening window 22 and the outer edge of the frame 23 into an accurate square shape, and the boundary between the frame 23 and the surface plate 21 is not uniform due to deformation due to the deviation of the wood. . The natural wood used for the core member 25, the surface plate 21, and the frame 23 cannot be completely deformed over time.

  The deformation of the wood occurs in the door assembling process and also after the assembling, and the finishing accuracy of the frame 23 and the surface plate 21 is lowered. Furthermore, the door of this structure has the fault that it is difficult to keep the surface plate 21 and the frame 23 in the same plane indefinitely due to the deviation of wood that occurs with time. When the surface plate 21 warps and the core member 25 and the frame 23 are deformed, the surface plate 21 and the frame 23 cannot be held on the same plane. When the door is used as a sliding door, if the frame 23 and the surface plate 21 are not flush with each other, the door cannot be opened and closed smoothly. Moreover, even when not used for a sliding door, if there is a step between the surface plate 21 and the frame 23, there is a drawback that it is noticeable and the beauty of the door is significantly reduced.

  The door shown in FIG. 2 has a feature that it can prevent a gap from being formed between the inside of the core member 25 and the frame 23 because the core member 25 is fitted into the U-shaped groove 27 of the frame 23. However, since the door with this structure also has a gap between the surface plate 21 and the frame 23, it is difficult to have a clean and beautiful design. This gap can be narrowed to make the design cleaner, but if the gap is narrowed, it becomes difficult to make the width of the gap uniform. This is because the processing accuracy and the frame distortion change the width of the gap.

  In the door of FIG. 3, the surface plate 21 adhered to both surfaces of the core member 25 is inserted into the U-shaped groove 27 provided outside the frame 23, so that a gap between the frame 23 and the surface plate 21 is inserted. Can be eliminated. However, in the door of this structure, the frame 23 and the surface plate 21 cannot be flush with each other. Therefore, in order to use as a sliding door, it is necessary to widen the distance between the doors, and the frame 23 protrudes from the surface plate 21. Therefore, it is impossible to make a clean design with no irregularities on the entire surface.

  The present applicant has developed a door shown in FIG. 4 for the purpose of eliminating the above-described drawbacks (see Patent Document 1). In the door of this figure, a decorative plate 24 is fixed to an opening window 22 provided on the surface plate 21 via a frame 23. In order to fix the surface plate 21 on both sides, a core member 25 is fixed between the surface plates 21 along the opening window 22. MDF (MEDIAM DENCITY FIBER BOAD) of the fiber board which is the surface board 21 is fixed to both surfaces of the core member 25. The surface plate 21 is provided with a step portion 28 on the surface side along the periphery of the opening window 22. The frame 23 has a rectangular shape along the opening window 22 of the door, and a decorative plate 24 is sandwiched and fixed on the inner periphery. Furthermore, the outer peripheral surface of the frame 23 is provided with a U-shaped groove 27 having a U-shaped cross section. A stepped portion 28 of the surface plate 21 is fitted into the U-shaped groove 27, and the stepped portion 28 of the fiber board fixed to both surfaces of the core member 25 is fixed with the frame 23. Further, a slit gap 29 is provided between the frame 23 and the stepped portion 28, and the slit gap 29 is painted and finished beautifully.

  In the door having this structure, the surface plate 21 is processed so as to have a stepped portion 28, and is inserted into the U-shaped groove 27 of the frame 23 to provide the slit gap 29. Therefore, the slit gap 29 formed on the surface cannot be completely eliminated. For this reason, there exists a fault which cannot be made into the beautiful design which the surface board 21 does not have a clearance gap. In addition, since the frame 23 is fixed inside the core member 25, after the surface plate 21 is fixed to both surfaces of the core member 25, the pair of frame frames 23 are assembled so as to sandwich the decorative plate 24. There is a fault that cannot be assembled efficiently.

  Furthermore, a door having the structure shown in FIGS. 5 and 6 has also been developed. (See Patent Documents 2 and 3)

Japanese Utility Model Publication No. 6-78583 JP 2003-56256 A JP 2008-75347 A

  The door of FIG. 5 is provided with a right-angle bent piece 30 formed at a right angle from the surface of the core member 25 along the inner surface on the surface plate 21 fixed to both surfaces of the core member 25. Further, a flexible hinge portion 31 that can be bent like a hinge from the right-angle bent piece 30 to the inside so that the decorative plate 24 can be clamped and fixed by the right-angle bent piece 30. Is provided. Since this door does not have a frame projection at the opening, it can be designed neatly. However, since the surface plate 21 is bent on the surface like a hinge and fixed to the core member 25, there is a drawback that a bent line 32 is formed on the surface of the surface plate 21. In addition, there is a drawback that it takes time to fix the right-angle bent piece inside the opening.

  Further, in FIG. 6, the side edge of the surface plate 21 is fixed to the frame member 34 with a unique structure. In this door, longitudinal grooves 33 are provided on both surfaces of the core material 25, and a frame material 34 having a C-shaped cross-section is fixed to the outer surface of the core material 25. Further, the door has the same thickness as the frame material 34. The face plate 21 is fixed to both surfaces of the core member 25 in close contact with the frame member 34. This door cannot be easily fixed to the core member 25 because the frame member 34 has a C-shaped cross section, and the surface plate 21 is fixed to the both sides of the core member 25 by bonding or the like. Therefore, there is a drawback that it is difficult to finish the boundary between the surface plate 21 and the frame member 34 neatly. This is because a gap or a step is formed between the surface plate 21 and the frame member 34. In particular, if there is a gap between the surface plate 21 and the frame member 34, the end face of the surface plate 21 is exposed in the gap, which makes it difficult to finish it cleanly. Furthermore, the disadvantage that the surface plate 21 contracts with time and a gap is formed between the surface plate 21 and the frame material 34 cannot be solved.

The present invention was developed for the purpose of overcoming all the drawbacks of conventional doors, and an important object of the present invention is to easily and easily mass-produce the surface plate at low cost. The object is to provide a door that can clean the boundary between the frame and the frame material in an ideal state.
Another important object of the present invention is to provide a door that can be fixed to a frame material so as not to be peeled off strongly even if a thin plate material is used for the surface plate.
Furthermore, another important object of the present invention is to provide a door that can securely fix the surface plate to the frame material while ensuring that the frame material does not protrude from the surface plate if necessary.

  Embodiments of the present invention will be described below with reference to the drawings. However, the embodiment described below exemplifies a door for embodying the technical idea of the present invention, and the present invention does not specify the door as follows.

  Further, in this specification, in order to facilitate understanding of the scope of claims, numbers corresponding to the members shown in the examples are indicated in the “claims” and “means for solving problems” sections. It is added to the members. However, the members shown in the claims are not limited to the members in the embodiments.

  The flush door shown in FIGS. 7 to 9 has a surface plate 1 fixed on both sides of a frame 5 that is a frame material 3. Further, the surface plate 1 opens an opening window 2, and a decorative plate 6 is fixed to the opening window 2 via a frame 4 that is a frame material 3. In the door shown in these drawings, the core material is not disposed inside the frame 5, but the core material can be provided in a region surrounded by the frame 5, the surface plate 1, and the frame 4. The core material reinforces the surface plate 1 by fixing the surface plate 1 to both sides by a method such as adhesion. Further, the core material can be connected to the frame to reinforce the door.

  The outer shape of the frame 5 is equal to the outer shape of the surface plate 1. The frame 5 includes a vertical frame 5A and a horizontal frame 5B that are fixed along the outer peripheral edge of the surface plate 1. The frame 5 has the surface plate 1 fixed to both sides by a method such as adhesion.

  The surface plate 1 has a flexible surface sheet 11 bonded to the surface of a surface plate 10 that is a fiber plate. The surface plate 1 using the surface plate 10 as a fiber plate can prevent warpage unique to wood. However, the surface plate can be made of wood material such as plywood or natural wood instead of the fiberboard. As the top sheet 11, a flexible sheet material such as a veneer obtained by thinly slicing wood, a synthetic resin sheet, or paper can be used. However, it is also possible to use a surface plate with a beautiful surface finish by painting the surface without adhering the surface sheet. Further, the surface plate is not necessarily bonded to the surface sheet, and natural wood or plywood can also be used. The surface plate 1 is NC processed to open the opening window 2. The front surface plates 1 on both sides open the opening window 2 at a position facing each other, that is, at the same position.

  FIG. 8 shows a cross-sectional view of a frame 5 that is a frame material 3 that fixes the surface plate 1 on both sides. This figure shows a portion for fixing the surface plate 1 to both surfaces of the vertical frame 5A which is the frame material 3. FIG. The surface plate 1 shown in this figure is provided with a bent connecting piece 7 which is bent toward the inside of the door at a side edge portion fixed to the vertical frame 5A which is the frame material 3. The bent connecting piece 7 is preferably bent at a right angle with respect to the door surface as shown in the cross-sectional view of FIG. However, the bent connecting piece does not necessarily have to be bent at a right angle with respect to the door surface. For example, the bent angle α with respect to the surface plate 1 can be set to 30 to 120 degrees. In the state where the bending angle α of the bent connecting piece is not a right angle, the surface plate is fixed to the frame member, and the end surface of the surface plate is an inclined surface, and the inclination angle of the inclined surface can be adjusted by the bending angle α.

  The surface plate 1 shown in the cross-sectional view of FIG. 8 is a plate material in which a flexible surface sheet 11 is bonded to the surface of the surface plate 10, so that the surface sheet 11 is not cut as shown in FIG. That is, the top sheet 11 is left, the inside of the top plate 1 is V-cut, the V-cut cut surfaces 12 are brought into contact with each other, the top sheet 11 is bent into a hinge shape, and then bent at a right angle. The bent connecting piece 7 is provided on the side edge. The surface plate 1 is simple, easy and clean by using the flexible surface sheet 11 as a hinge by V-cutting the entire surface plate 10 so as not to cut the surface sheet 11. The bent connecting piece 7 can be provided by bending at a right angle. However, it is also possible to V-cut leaving the thin film on the surface plate, use both the thin film of the surface plate and the surface sheet as hinges, and bend at a right angle to provide a bent connecting piece. Completely cut and cut a part of the surface sheet, V-cut to leave a thin film on it, and use the thin film of the surface sheet as a hinge to bend at a right angle to provide a bent connecting piece You can also. The surface plate 1 having a flexible surface sheet 11 bonded to the surface can be bent at a right angle using the surface sheet 11 as a hinge, and the outer corner portion to be bent can be finished finely.

  Further, as shown in FIG. 11 and FIG. 12, the surface plate 1 has a bent connecting piece 7 which is V-cut at two inner portions in parallel and bent at two locations, and the whole is bent at a right angle. It can also be provided. Further, although not shown, the surface plate may be provided with a bent connecting piece that is bent at a right angle by V-cutting a plurality of locations in parallel.

  Furthermore, the surface plate made of plywood or top plate to which the surface sheet is not bonded is V-cut leaving a thin film that can be bent as a hinge on the surface of the surface plate, and the thin film is bent as a hinge to make a right angle. A bent connecting piece that is bent can be provided. This surface plate is humidified and further heated to make the wood soft and bend beautifully without damaging the thin film. Further, by providing a plurality of rows of V-cuts in parallel and reducing the bending angle of one V-cut, the natural wood can be bent without being damaged.

  The front plate 1 can fix the bent connecting piece 7 at a right angle by adhering the V-cut cut surface 12. However, the door of the present invention is fixed to the frame material 3 by inserting the bending connecting piece 7 into the fitting groove 8 of the frame material 3 and bonding the surface plate 1 to the frame material 3. It is not always necessary to bond the cut surface 12 in the previous step of fixing to the substrate. That is, the surface plate 1 has the V-cut cut surface 12 bonded thereto and the bent connecting piece 7 is inserted into the fitting groove 8 of the frame material 3 or the bent connecting piece 7 is inserted into the fitting groove 8 without bonding. It can be inserted and attached to the frame material 3 and fixed. Preferably, the front plate 1 is bonded and fixed to the frame member 3 by inserting the bent connecting piece 7 into the fitting groove 8 without bonding the cut surface 12.

  The vertical frame 5A, which is the frame material 3, is made of natural wood or LVL to which a plurality of woods are bonded, and the fitting grooves 7 into which the bent connecting pieces 7 of the surface plate 1 are inserted along the longitudinal direction on both sides thereof. 8 is provided. Since the fitting groove 8 inserts and fixes the bent connecting piece 7, its width (w) is substantially equal to the thickness (t) of the bent connecting piece 7, for example, the thickness of the bent connecting piece 7. It is 0 mm to 0.5 mm wider than the thickness (t), preferably 0.1 mm to 0.3 mm wider. The fitting groove 8 into which the bent connecting piece 7 formed by bending the surface plate 1 having a thickness (t) of 2.75 mm is inserted has a width (w) of 2.85 mm to 3.05 mm, for example 3 0.0 mm, it can be inserted and fitted without a gap. Further, the depth (h) of the fitting groove 8 is made deeper than the width of the bent connecting piece 7, that is, the length (l) protruding perpendicularly. The depth (h) of the fitting groove 8 is, for example, 5.2 mm, and the bent connecting piece 7 having a protruding length (l) of 4.0 mm to 4.8 mm can be inserted and fixed securely.

  The fitting groove 8 specifies the position where the surface plate 1 is connected at that position. The fitting groove 8 is, for example, 3 mm away from the outer surface 3A of the vertical frame 5A that is the frame material 3, that is, the interval (d) between the fitting groove 8 and the outer surface 3A of the frame material 3 is 3 mm. . The door for fixing the surface plate 1 to the frame material 3 has an exposed portion 3X of the frame material 3 with a width of 3 mm from the side edge of the surface plate 1. However, the distance (d) between the fitting groove and the outer surface of the frame material can be, for example, 1 mm to 30 mm, preferably 2 mm to 20 mm, and more preferably 2 mm to 10 mm. Although this space | interval (d) is set to the optimal value from the design of a door, it can widen and can insert and fix the bending connection piece 7 to the fitting groove | channel 8 firmly, can narrow and can refresh an external appearance design.

  Furthermore, the vertical frame 5A, which is the frame material 3 shown in FIG. 8, has the exposed surfaces 3D of the exposed portions 3X protruding from the side edges of the surface plate 1 in the outer circumferential direction, and both surfaces of the vertical frame 5A. It protrudes outward from the facing surface 3C to be bonded. The vertical frame 5A, which is the frame material 3 shown in FIG. 8, has a protruding amount (T) in which the exposed surface 3D of the exposed portion 3X protrudes from the opposing surface 3C smaller than the thickness (t) of the surface plate 1, The boundary portion between the surface plate 1 fixed to the material 3 and the exposed portion 3X has a stepped shape. However, although not shown, it is needless to say that the door of the present invention can have a protruding amount (T) larger than the thickness (t) of the surface plate so that the exposed portion protrudes from the surface plate. Yes. Further, in the vertical frame 5A which is the frame material 3 shown in FIG. 11, the exposed surface 3D of the exposed portion 3X is disposed on both sides of the vertical frame 5A and inside the facing surface 3C to which the surface plate 1 is bonded. That is, the exposed surface 3D of the exposed portion 3X is disposed lower than the facing surface 3C, and the boundary portion between the surface plate 1 fixed to the frame material 3 and the exposed portion 3X has a step shape. However, in the vertical frame 5A, which is the frame member 3, as shown in FIG. 13, the protrusion amount (T) of the exposed surface 3D of the exposed portion 3X protruding from the facing surface 3C is equal to the thickness (t) of the surface plate 1. And the surface plate 1 and the exposed part 3X can also be made into the same plane. With this structure, the boundary portion between the surface plate 1 and the vertical frame 5 </ b> A that is the frame material 3 can be designed to be neat and clean.

  The fitting groove 8 inserts the bent connecting piece 7 and fixes the surface plate 1 to the vertical frame 5 </ b> A that is the frame material 3. Therefore, the fitting groove 8 is provided on both surfaces of the vertical frame 5A at an angle at which the bent connecting piece 7 can be inserted. Since the door of FIG. 8 is provided with the bending connection piece 7 that bends the bending connection piece 7 at a right angle to the door surface, the fitting groove 8 is also provided in a shape that is perpendicular to both surfaces. Although not shown, the frame material for fixing the surface plate that does not make the bent connecting piece a right angle is provided with an fitting groove at an angle at which the bent connecting piece can be inserted, and the bent connecting piece is inserted and fixed.

  In the frame material 3 of FIG. 8, a flexible decorative sheet 14 is bonded to the surface of the core material 13. The decorative sheet 14 is inserted from the surface of the core material 13 to the inside of the fitting groove 8. The surface of the frame material 3 can be finely finished with the decorative sheet 14, and the edge of the decorative sheet 14 is inserted into the fitting groove 8 and fixed with the bent connecting piece 7 of the surface plate 1. Thus, there is a feature that can be reliably fixed without peeling. The decorative sheet 14 is made of the same material as the surface sheet 11 adhered to the surface of the surface plate 1 or a different material, and has the same pattern or a different pattern.

The above door is assembled in the following steps.
(1) V-cut the inner surface of the side edge portion of the surface plate 1 fixed to the vertical frame 5 </ b> A that is the frame material 3 to provide the bent connection piece 7. The surface plate 1 in which the surface sheet 11 is bonded to the surface plate 10 V-cuts the surface plate 10 without cutting the surface sheet 11. The cut surface 12 formed by V-cutting is not necessarily bonded to fix the bent connecting piece 7 at a right angle, but is provided with a bent connecting piece 7 that can be bent at a right angle.
(2) The fitting grooves 8 extending in the longitudinal direction are provided on both surfaces of the vertical frame 5A, which is the frame material 3, using a rotating grooved cutting tool.
(3) 5 A of vertical frames adhere | attach the decorative sheet 14 on both surfaces from the outer side of the core material 13, and insert the both-sides edge of the decorative sheet 14 in the fitting groove | channel 8.
