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.

Furthermore, the conventional furniture construction flat boards and panels that form the background of this invention were
22520 and Utility Model Application Publication No. 140628,
Each is disclosed.

The flat board for furniture construction 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.

Furthermore, the panel disclosed in Japanese Utility Model Application Publication No. 52-140628 has a rectangular material plate with a flexible surface material adhered to at least one surface, and a face plate portion having a predetermined angle of inclination on both sides. , a large number of side plate parts connected closely to each other via the surface material and having a slope of a required angle on both sides are successively formed, and each of the face plate parts and the side plate parts are close to each other. A decorative board is formed by adhering a decorative board on an inclined surface to form a large number of successive sections with a trapezoidal cross section, and then adhering the ends of each side section to the surface of a rectangular core board.

(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 furniture construction flat board disclosed in Japanese Utility Model Application Publication No. 53-22520, a relatively large panel must be bent into an annular shape.
It is difficult to fold the panels. 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.

Furthermore, in the panel disclosed in Japanese Utility Model Application Publication No. 52-140628, since the face plate member is separated from the core material, the strength of that portion is weak.

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 consists of a substrate having a decorative sheet pasted on its surface and a bending groove formed on its back side, and a substrate whose front outer surface is chamfered, and whose front outer surface is chamfered. spanning between left and right support members for defining left and right ends of the board, to which the back side of the board is adhered across the front surface, chamfered surface, side surfaces and back surface, and the left and right support members; The folding member includes a crosspiece attached to the supporting material so as to be recessed from the surface of the supporting material, and a back plate attached to the back surfaces of the left and right supporting materials so as to cover the crosspiece. The curved groove is formed to correspond to the corner of the supporting material, and the bent groove is expanded and closed to form a partially recessed decorative plate portion on the surface thereof, and the decorative sheet is This is an opening member, such as a door, which is bent along the corner of the supporting material and has a chamfered surface formed on a part thereof.

(Operations and effects of the invention) Since the invention is configured as described above,
It is possible to obtain an aperture member that is relatively lightweight and strong without requiring much time and effort to manufacture, and by changing the decorative sheet, it is possible to change the overall structure and obtain an interesting aperture member. Moreover, the changes can be made relatively easily, making it possible to produce a wide variety of products in small quantities.

The above objects, other objects, features and advantages of this 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.

This 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 different, and the frame portion and the decorative plate portion may have the same pattern, or the door may be formed of only the decorative plate portion.

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 opened so that when the decorative sheet 4 is bent, the groove walls are in close contact with each other to form an appropriate angle.
Further, the depth is set so as to extend from the back surface of the substrate 3 toward the back surface of the decorative sheet 4 so as to reach the back surface of the decorative sheet 4 without damaging it.

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

On the other hand, a support member is prepared in which crosspieces 7 are provided at a predetermined interval between the left and right support members 6 whose front outer sides are chamfered, and the support members 6 defining the left and right ends of the door are provided. Across the surface side of both left and right ends,
The flat substrate 3 is provided, and the decorative sheet 4 is bent at the bending grooves 5 on the chamfered side, left and right sides, and the back side of the support member 6, so that the substrate 3 is bent on the back side. Support material 6
is attached to the surface of the

In this embodiment, the frame portion 1 and the decorative plate portion 2 are provided with a step, as shown in FIG. 3, and a portion of the decorative plate portion 2 is recessed.

In this embodiment, a crosspiece 7 spanning between the left and right supports 6 is attached to a support 6 recessed lower than the surface of the support 6. Then, an intervening material 8 is provided between a part of the substrate 3 constituting the decorative plate part 2, and the bending groove 5' is widened and the substrate 3 is stuck to the crosspiece 7 in a recessed state. At the same time, the bending groove 5 is attached to the closed intervening material 8. Therefore,
A part of it is formed to have the same height as the frame part 1.

In this way, a three-dimensional door in which the frame portion 1 and the decorative plate portion 2 can be clearly distinguished is formed from the monolithic substrate 3 and the decorative sheet 4.

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 sheets may be changed in various ways as shown in FIG. It may also be used as a door for unit furniture, etc.
