Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an opening member suitable for use as a door for fittings or furniture.

(Prior art) Conventional doors generally have a frame covered with thin plates or glass, but if you want to create a door with a solid feel, the force and weight will increase, making handling and construction inconvenient. Furthermore, the frames and the mirror panels fitted between them are almost uniform, and because of the difficulty of machining them, it has not been possible to create anything interesting.

Therefore, the inventor of the present invention previously proposed a vanity door for storage devices disclosed in Japanese Patent Application Laid-Open No. 54-92871.

Further, conventional doors with a flush structure and a flush board for furniture construction, which are the background of this invention, are disclosed in Japanese Utility Model Application No. 53-55930 and Japanese Utility Model Application Publication No. 53-22520, respectively.

The door of the flush structure disclosed in Japanese Utility Model Application Publication No. 53-55930 has a structure in which one frame or frame is provided only in the center of a base material bent into a rectangular tube shape.

Further, a furniture construction flat board disclosed in Japanese Utility Model Application Publication No. 53-22520 has a structure in which a core material is provided on both sides and in the center of an annularly bent panel.

(Problem to be solved by the invention) However, in this vanity door for storage devices disclosed in JP-A No. 54-92871, the decorative board material with concave portions and convex portions is difficult to manufacture. There is.

Furthermore, in the door of the flush structure disclosed in Japanese Utility Model Application Publication No. 53-55930, the relatively large base material serving as the door must be bent into an annular shape, which makes the bending operation difficult. Moreover, the part corresponding to the surface of the door cannot be said to be very interesting. Furthermore, since the structure does not include supporting materials at both ends of the bent base material, it is difficult to bend the base material into a predetermined shape, and the strength of the bent portion and the whole is weak.

Furthermore, even in the case of the flash board for furniture construction disclosed in Japanese Utility Model Application Publication No. 53-22520, since a relatively large panel must be bent into an annular shape, the work of folding the panel is still difficult. Moreover, on the surface level, it cannot be said to be very interesting. Furthermore, since each core material is provided separately, the strength of the folded portion of the panel is slightly stronger, but the overall strength is weaker.

Therefore, the main purpose of this invention is to be able to obtain an opening member that is relatively lightweight and strong, without requiring much time and effort to manufacture, and to create an interesting structure by changing the parts corresponding to the frames and head panels. It is an object of the present invention to provide an opening member that can be obtained at a low cost, that can be changed relatively easily, and that enables production of a wide variety of products in small quantities. .

(Means for Solving the Problems) This invention is based on a frame portion and a flat plate whose surface is curved outward, with a decorative sheet pasted on the surface and bent grooves and narrow grooves formed on the back side. A substrate for configuring a decorative plate portion, the front side of which is curved outward, and the back side of the substrate is pasted over the front, side, and back surfaces.
Left and right support members for defining the left and right ends of the substrate, crosspieces that span between the left and right support members and are joined to the substrate, and a back plate attached to the back surface of the support material, the bending groove is formed to correspond to the corner of the support material, and the narrow groove is formed to correspond to the front surface side of the support material. Further, the decorative sheet is bent along the surface of the supporting material, and a curved surface is formed in a part of the decorative sheet, which is an opening member such as a door.

(Functions and effects of the invention) Since the invention is configured as described above,
It is possible to obtain an opening member that is relatively lightweight and strong without requiring much time and effort to manufacture, and by changing the decorative sheet, bending grooves, and thin grooves, the overall structure can be changed, making it more interesting. It is possible to obtain an opening member, and it is also relatively easy to change the opening member, making it possible to produce a wide variety of products in small quantities.

The above-mentioned objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

(Example) Figures 1 to 3 are views showing a door according to an embodiment of the present invention, with Figure 1 being a front view thereof, Figure 2 being a longitudinal sectional view thereof, and Figure 3 being a cross sectional view thereof. It is a diagram.

The main door includes a frame part 1 and a decorative plate part 2 forming a mirror plate part formed between the frame parts 1.

The frame portion 1 and the decorative plate portion 2 are formed of a substrate 3,
The substrate 3 is made of a wood-based material such as plywood, particle board, hardboard, or the like.

A decorative sheet 4 such as a vinyl chloride resin sheet or a decorative natural wood veneer is adhered to the surface of the substrate 3. In this embodiment, a synthetic resin sheet such as a vinyl chloride resin sheet with a wood grain pattern or the like appropriately printed on the surface is used.

In this embodiment, the decorative sheet 4 is attached to the substrate 3 and the bending grooves 5 are formed.
A straight grain pattern is formed on the decorative sheet 4 corresponding to
The decorative sheet 4, which corresponds to the decorative plate section 2 forming the mirror panel section, is attached to the substrate 3 so that the wood grain runs in the longitudinal direction, and the decorative sheet 4, which corresponds to the decorative plate section 2 forming the mirror panel section, is attached to the substrate 3 so that the wood grain in the straight-grain pattern runs along the width direction. are doing. Thus, when the decorative sheet 4 is bent at the bending grooves 5 to form a door, the straight-grained decorative sheet 4 portions will appear as if they are forming a stile;
A door with a three-dimensional effect can be easily obtained using a single substrate 3 and decorative sheet 4.

However, unlike the embodiments described above, the frame portion and the decorative plate portion may not be made different, and the frame portion and the decorative plate portion may have the same pattern.

In addition, when using a natural wood decorative veneer as the decorative sheet 4, cracking of the decorative sheet 4 can be prevented by sandwiching a nonwoven fabric made of synthetic fiber or the like as a cushioning material between it and the substrate 3. Can be done.

As shown in FIG. 4, the substrate 3 has a plurality of bent grooves 5 each having a V-shaped cross section cut in the longitudinal direction using a cutter or the like. As shown in FIG. 3, the bending grooves 5 are formed so that when the decorative sheet 4 is bent, the groove walls are in close contact with each other to form an appropriate angle, and the depth thereof is smaller than the back surface of the substrate 3. It is formed toward the back surface of the decorative sheet 4 so as to reach the back surface of the decorative sheet 4 but not to damage it.

Then, the decorative sheet 4 is bent at the bending groove 5 portion, and the bending groove 5 is closed to form a flat substrate 3.
is formed into a predetermined shape.

On the other hand, a support is prepared in which crosspieces 7 are provided at a predetermined interval between the left and right supports 6 whose front surfaces are curved outward, and the supports 6 define the left and right ends of the door. Across the surface side of both the left and right ends of
The flat plate-shaped substrate 3 is disposed, and the decorative sheet 4 is bent at the bending grooves 5 over the front surface, left and right sides, and back side of the support material 6, so that the substrate 3 is bent on the back surface thereof. is attached to the surface of the support material 6.

Further, as shown in FIG. 5, a plurality of narrow grooves 8 are cut in the longitudinal direction using a cutter, a circular saw, etc. in the part of the board 3' corresponding to the frame part 1 of the board 3, as shown in FIG. A frame portion 1 having an arc-shaped curved surface is formed by being fixed to a supporting member 6 having an arc-shaped end surface.

In the example illustrated in FIG. 1, also on the back side of the door, a back plate 9 is spanned between the left and right supporting members 6 and is attached, facing the flat substrate 3.

In addition, the wood grain pattern of the decorative sheet may be changed in various ways as shown in FIG. 6, and when actually using the opening member of the present invention, two or more sheets may be combined as shown in FIG. It can also be used as a door for unit furniture, etc.
