【０００１】
【発明の属する技術分野】
本発明は化粧板の製造方法に関する。
【０００２】
【従来の技術】
従来、この種の化粧板の製造方法として以下の如きものは知られている。
上下框・左右框の相互に隣接する端部にダボ嵌合孔を形成する工程と、上下框・左右框の内側部に鏡板が嵌まる嵌合溝を形成する工程と、上下框・左右框の相互に突き合う面に接着剤を塗布する工程と、鏡板の端部を嵌合溝に嵌めるようにして、且つ、接着剤が付けられたダボを相互に隣接する框のダボ嵌合孔に跨るように嵌めて框同士を連結する工程と、框同士が突き合うような力を加えつつ乾燥装置によって接着剤を乾燥させる工程とを有するものは知られている。
【０００３】
【従来技術の欠点】
前記従来の化粧板の製造方法には以下の如き欠点があった。
鏡板を含む仮想面において框を鏡板に向けて移動させて、框同士の、相互に突き合う面を接着剤で接着すると共にダボを介して框同士を連結するものであったため、即ち、化粧板を製造した直後の接着剤が硬化するまでの間においては、框同士の接続部が分離するおそれがある状態で框同士を連結するものであったため、框同士が突き合うような力を加えつつ乾燥装置によって接着剤を乾燥させる工程を必ず必要とし、その分だけ製造効率が悪いという欠点があった。
【０００４】
【課題を解決するための手段】
本発明は前記欠点を解消するために以下の如き手段を採用した。
請求項１の発明は、上下框・左右框の相互に隣接する端部の一方にありを形成し、同他方にありが嵌まるあり溝を形成する工程と、左右框・下框の内側部に鏡板が嵌まる嵌合溝を形成すると共に上框の内側部に下框の嵌合溝より深い、鏡板が嵌まる嵌合溝を形成する工程と、ありをあり溝に嵌合させて上框の左右端部に左右框の上端部を固定する工程と、左右框の嵌合溝に鏡板の左右部を左右框の下側からスライド嵌めして鏡板の上端部を上框の嵌合溝に嵌めて、鏡板の下端部が下框と衝突・干渉しない状態とする工程と、ありをあり溝に嵌合させて左右框の下端部に下框の左右端部を固定する工程と、鏡板を下降させてその下端部を下框の嵌合溝に嵌めて全ての嵌合溝に鏡板が嵌まった状態とする工程とを有するものである。
請求項２の発明は、上下框・左右框の相互に隣接する端部の一方にありを、同他方にありが嵌まるあり溝を、該あり及びあり溝の嵌め込み方向が上下框・左右框の框表面に直交するように夫々形成する工程と、左右框の内側部に鏡板が嵌まる嵌合溝を形成する工程と、ありをあり溝に嵌合させて上框の左右端部に左右框の上端部を固定する工程と、左右框の嵌合溝に鏡板の左右部を左右框の下側からスライド嵌めして鏡板の下端部が下框と衝突・干渉しない状態とする工程と、ありをあり溝に嵌合させて左右框の下端部に下框の左右端部を固定する工程とを有するものである。
請求項３の発明は、前記下框の内側部又は前記上框及び下框の両内側部を鏡板が嵌まる嵌合溝を有しない形状に形成する工程と、前記ありをあり溝に嵌合させて左右框の下端部に下框の左右端部を固定する工程の後に、前記上下框及び左右框の各内側面の前部又は前後部に装飾材を取り付ける工程とを有する請求項２に記載のものである。
【０００５】
【発明の効果】
本発明は前記した如き構成によって以下の如き効果を奏する。
請求項１の発明によれば、框同士をありとあり溝とによる機械的嵌合で連結・固定出来るので、従来必要であった接着剤乾燥工程を必要とせず、製造効率を向上させることが出来る。また、ありとあり溝との嵌合により上框の左右端部に上端部を固定した左右框の嵌合溝に鏡板の左右部を左右框の下側からスライド嵌めして鏡板の上端部を下框の嵌合溝より深い上框の嵌合溝に嵌め、鏡板の下端部が下框と衝突・干渉しない状態とし、ありとあり溝との嵌合により左右框の下端部に下框の左右端部を固定した後、鏡板を下降させて下端部を下框の嵌合溝に嵌めて全ての嵌合溝に鏡板が嵌まった状態とする。これにより、鏡板の四側縁部が四方の框の嵌合溝に嵌まったものとすることが出来、その結果、鏡板の四側縁部が外部から見えないようにすることが出来るので、鏡板の四側縁部の化粧処理が不要である。
請求項２の発明によれば、框同士をありとあり溝とによる機械的嵌合で連結・固定出来るので、従来必要であった接着剤乾燥工程を必要とせず、製造効率を向上させることが出来る。また、ありとあり溝とを上下框・左右框の框表面に直交する方向に嵌合させて上框の左右端部に上端部を固定した左右框の嵌合溝に鏡板の左右部を左右框の下側からスライド嵌めし、鏡板の下端部が下框と衝突・干渉しない状態とした後、ありとあり溝とを上下框・左右框の框表面に直交する方向に嵌合させて左右框の下端部に下框の左右端部を固定する。
請求項３の発明によれば、請求項２の発明において、下框の内側部又は上框及び下框の両内側部を鏡板が嵌まる嵌合溝を有しない形状とし、ありとあり溝とを嵌合させて左右框の下端部に下框の左右端部を固定した後、上下框及び左右框の各内側面の前部又は前後部に装飾材を取り付ける。

[0006]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
In this description, “front” refers to the front side of FIG. 1, “back” refers to the back side, “left” refers to the left side of FIG. 1, and “right” refers to the right side of FIG. Further, “upper” means the upper side of FIG. 1, and “lower” means the lower side of the figure.
[0007]
First, the decorative board 1 that is a furniture or a door of a room manufactured by the method of the embodiment of the present invention will be described. The decorative plate 1 has a frame 5 composed of an upper collar 2, a lower collar 3, and left and right collars 4, and a mirror plate 7 fitted in the frame 5.
As is well known, each of the end faces and the outer faces of the upper collar 2, the lower collar 3 and the left and right collars 4 form 45 degrees as seen from the front.
[0008]
A 9 is formed at the left end of the upper collar 2, and a groove 10 is formed at the right end.
A groove 10 is formed at the left end of the lower collar 3 and a groove 9 is formed at the right end.
A groove 10 is formed at the upper end of the port 4 and a groove 9 is formed at the lower end.
9 is formed at the upper end of the starboard 4 and a groove 10 is formed at the lower end.
[0009]
As shown in FIG. 6, the front and rear thickness of the dovetail 9 is made thinner than the front and rear thicknesses of the flanges 2, 3 and 4. Naturally, the longitudinal depth of the dovetail groove 10 is equal to the longitudinal thickness of the dovetail 9. The end portion of the dovetail 9 in the dovetail groove 10 is a constricted portion 9a that is squeezed in the fitting direction. In this embodiment, the concavity 9a is formed by chamfering both tapered edges (edges that are tapered when viewed from the front) on the front side of the dovetail 9 (see FIG. 4). However, the two taper edges may be formed by forming convex curved surfaces (so-called rounded shapes), and further, the two taper edges on the side where the dovetail 9 is fitted into the dovetail groove 10 are formed. At least one may be chamfered or rounded.
[0010]
The frame 5 is configured by fitting the dovetail 9 of each of the flanges 2, 3, 4 and the dovetail groove 10.
[0011]
A fitting groove 12 is formed in the inner part of the upper collar 2 (the part facing the center surrounded by the frame 5), and a fitting groove 13 is formed in the inner parts of the lower collar 3 and the left and right collars 4. The depth of the fitting groove 13 is “k”, and the depth of the fitting groove 12 is “l” (l> k). The reason will be described later.
The end plate 7 is attached to the frame 5 with its peripheral edge fitted into the fitting groove 12 and the fitting groove 13.
In addition, the depth of the fitting groove 13 of the lower rod 3 may be deeper than “k”, and a spacer may be interposed so that the depth becomes “k” later.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, the assembly method (manufacturing method) of the decorative board 1 is demonstrated.
In actual work, the decorative plate 1 is manufactured in a horizontal state, that is, in a state where the rear surface of the decorative plate 1 faces downward. Then, in order to make the explanation easy to understand, it is assumed that the decorative board 1 is completed in the vertical state.
[0013]
[First step]
The upper flange 2, the lower rod 3 and the left and right rods 4 are each provided with a 9 at one of the adjacent ends, and the other 9 is formed with a dovetail groove 10 into which the 9 is fitted.
Further, a fitting groove 13 into which the end plate 7 is fitted is formed on the inner side of the lower rod 3 and the left and right side rods 4 and the inner end of the upper rod 2 is fitted with the end plate 7 which is deeper than the fitting groove 13 of the lower rod 3. A joint groove 12 is formed.
[0014]
[Second step]
The dovetail 9 is fitted into the dovetail groove 10, and the upper ends of the left and right rods 4 are fixed to the left and right ends of the upper rod 2.
[0015]
[Third step]
The left and right ends of the end plate 7 are slid and fitted into the fitting grooves 13 of the left and right sides 4 from the lower side of the left and right side plates 4, and the upper end of the end plate 7 is fitted into the fitting grooves 12 of the upper side 2. Make sure that it does not collide or interfere with the lower arm 3.
The upper and lower lengths of the end plate 7 are “m”, the inner lengths of the upper plate 2 and the lower plate 3 of the decorative plate 1 are “n”, and the upper end of the end plate 7 is fitted into the fitting groove 12 when the decorative plate 1 is completed. When the length that fits into “p” is “p”, the following relationship is established so as to achieve the above state.
l> mn
m = k + n + p
[0016]
[Fourth step]
The dovetail 9 is fitted into the dovetail groove 10, and the left and right ends of the lower rod 3 are fixed to the lower ends of the left and right rods 4. Specifically, this operation is performed by moving the lower rod 3 forward after the lower rod 3 is positioned behind the rear surface of the left and right rods 4. That is, in order to perform this operation, it is necessary to position the lower edge of the end plate 7 at a position where it does not collide with or interfere with the lower eyelid 3.
[0017]
[Fifth step]
The end plate 7 is lowered and the lower end thereof is fitted into the fitting groove 13 of the lower collar 3 so that the end plate 7 is fitted in all the fitting grooves 12 and 13.
[0018]
[Modifications]
A description will be given below of modifications and the like.
(1) In this specification, “with” includes all fitting protrusions whose tip end bulges in a direction perpendicular to the fitting direction. Further, the dovetail groove refers to a recess in which the dovetail is fitted.
(2) FIG. 8 shows a modified example of the groove 10. In FIG. 8, the end portion of the dovetail groove 10 on the side of the inlet 17 into which the dovetail 9 is fitted is an expanded portion 10 a that expands toward the inlet 17 side.
In FIG. 8, the expanding portion 10 a is chamfered on both taper edges (edges that are tapered when viewed from the rear surface) on the rear portion (lower side portion in FIG. 8) side of the dovetail groove 10. However, it may be formed by making both tapered edges into convex curved surfaces (form a so-called round), and further, the side of the inlet 17 into which the dovetail groove 10 is fitted. Chamfering or rounding may be formed on at least one of the two tapered edges at the end of the head.
(3) The material of the end plate 7 is arbitrary, such as a wood-based material, glass, or metal.
(4) The end plate 7 may be attached to the frame 5 via an adhesive or without an adhesive.
(5) When the fitting groove 13 is not formed in the lower collar 3, the [fifth step] is not performed. In that case, (m = n + p) is satisfied and l ≧ p may be satisfied. In this case, a decorative material (a so-called molding) is attached to the front part or the front and rear part of the inner surface of the frame 5.
(6) When the fitting groove 12 is not formed in the upper collar 2 and the fitting groove 13 is not formed in the lower collar 3, [third step] is as follows. Moreover, [5th process] is not performed.
The left and right ends of the end plate 7 are slid into the fitting grooves 13 of the left and right end 4 from the lower side of the left and right end 4 so that the lower end of the end plate 7 does not collide with or interfere with the lower end 3.
In this case, m = n. In this case, a decorative material (so-called molding) is attached to the front part or front and rear part of the inner surface of the frame 5.
(7) When fitting the dovetail 9 and the dovetail groove 10, an adhesive may or may not be applied.
