Description
本発明は、熱可塑性樹脂をブロー成形することにより製造される表皮つき折り畳みパネルに関するものである。 The present invention relates to a folding panel with a skin manufactured by blow molding a thermoplastic resin.
図１は従来の表皮つきの折り畳みパネル、図２は図１のＡ−Ａ断面、図３は同じく図１のＢ−Ｂ断面を表す。 1 shows a conventional folding panel with a skin, FIG. 2 shows a cross section AA in FIG. 1, and FIG. 3 shows a cross section BB in FIG.
従来、図１ないし図３に示すような、表皮２が装着された折り畳みパネル１をブロー成形により製造する場合、該表皮２を見栄え良く装着する方法として「木目込み」と言う技法がある。これは表皮２の端縁をパネル１の表面の周溝３にはめ込んで隠す手法として特許文献１に示されるように公知である。
尚、ここで言う周溝３とは、図１に示すように前記折り畳みパネル１の表面の全周にわたって閉曲線として形成される断面Ｕ字状の溝を意味する。
In addition, the circumferential groove 3 said here means the groove | channel of U-shaped cross section formed as a closed curve over the perimeter of the surface of the said folding panel 1 as shown in FIG.
しかるに、該折り畳みパネル１の中間部にヒンジ部４を必要とするような場合、該ヒンジ部４を薄く成形しなければならないが、図２に示すように該周溝３と該ヒンジ部４とが交差する位置における溝裏凸部６によって生じる段差がリブの役目をはたすため、該ヒンジ部４の屈曲方向の断面二次モーメントの増大を招いて該ヒンジ部４の屈曲性を著しく損なっていた。 However, when the hinge part 4 is required at the intermediate part of the folding panel 1, the hinge part 4 has to be formed thin. However, as shown in FIG. 2, the circumferential groove 3 and the hinge part 4 Since the step generated by the groove-back convex portion 6 at the position where the two intersect each other acts as a rib, the bending moment of the hinge portion 4 is significantly impaired due to an increase in the second moment of section in the bending direction of the hinge portion 4. .
解決しようとする課題は、表皮つき折り畳みパネルの中間部にヒンジ部を必要とするような場合、該ヒンジ部を薄く成形しなければならないが、木目込み用の周溝と該ヒンジ部とが交差する位置における溝裏凸部によって生じる段差がリブの役目をはたすため、該ヒンジ部の屈曲方向の断面二次モーメントの増大を招いて該ヒンジ部の屈曲性を著しく損なうという点である。本発明は上記の点を解決するためになされた。 The problem to be solved is that when a hinge part is required in the middle part of the folding panel with skin, the hinge part must be thinly formed, but the peripheral groove for wood grain crossing the hinge part The level difference caused by the groove back convex portion at the position plays the role of a rib, so that the second moment of the section in the bending direction of the hinge portion is increased, and the flexibility of the hinge portion is remarkably impaired. The present invention has been made to solve the above-described points.

を設けたことを最も主要な特徴とする。
また、折り畳み方向における溝裏凸部のえぐられ部の断面二次モーメントが、えぐられ部以外の溝裏凸部の断面二次モーメントより小さいことを第2の主要な特徴とする。
また、ヒンジ部における周溝は、このヒンジ部を断面Ｕ字状に成形したものであることを第３の主要な特徴とする。
The present invention relates to a folding panel manufactured by blow molding a thermoplastic resin.
A circumferential groove provided over the entire circumference, and an epidermis in which an edge is fitted in the circumferential groove,
A hinge portion for folding in a state of crossing the circumferential groove, and a groove back convex portion at a position where the circumferential groove and the hinge portion intersect.
The most important feature is the provision of a punched portion that does not penetrate the front and back of the hinge portion .
In addition, the second main feature is that the secondary moment of the cross-section of the groove back convex portion in the folding direction is smaller than the cross-section secondary moment of the groove back convex portion other than the cross-over portion.
The third main feature of the circumferential groove in the hinge portion is that the hinge portion is formed in a U-shaped cross section.
本発明によれば、周溝とヒンジ部とが交差する位置における溝裏凸部によって段差がついたヒンジ部が、えぐられ部により段差を緩和ないし解消されているため、該ヒンジ部の屈曲性を損なうことなく、見栄えの良い、表皮つきの折り畳みパネルを得ることができるという利点がある。 According to the present invention, since the circumferential groove and the hinge portion is a hinge portion with a stepped by Mizoura protrusion at a position crossing has been alleviated or eliminated the step by gouged portion, bending of the hinge portion There is an advantage that it is possible to obtain a foldable panel with a good skin without damaging the appearance.
ヒンジ部の屈曲性を損なうことなく、見栄えの良い、表皮つきの折り畳みパネルを得るという目的を、表面に設けられた周溝と、該周溝に端縁をはめ込まれた表皮と、折りたたむためのヒンジ部と、該周溝と該ヒンジ部とが交差する位置における溝裏凸部にえぐられ部を設けることによって、ブロー成形の持つ経済性を損なわずに実現した。 For the purpose of obtaining a foldable panel with a good skin without impairing the flexibility of the hinge part, a circumferential groove provided on the surface, a skin with an edge fitted in the circumferential groove, and a hinge for folding By providing a cut- out portion on the groove back convex portion at a position where the portion, the circumferential groove and the hinge portion cross each other, it has been realized without impairing the economic efficiency of blow molding.
本発明の構成を発明の実施の形態に基づいて説明すると次の通りである。尚、従来例と同一の符号は同一の部材を表す。 The configuration of the present invention will be described based on the embodiments of the invention as follows. In addition, the same code | symbol as a prior art example represents the same member.
図４、図５は本発明の１実施例を示すものであり、図１のＡ−Ａ断面に相当するものである。図４に示すように先ずヒンジ部４を、周溝３をよけるようにブロー成形用金型（図示せず）上で薄く設定する。 4 and 5 show an embodiment of the present invention, which corresponds to the AA cross section of FIG. As shown in FIG. 4, the hinge portion 4 is first set thin on a blow molding die (not shown) so as to avoid the circumferential groove 3.

図７は本発明による該折り畳みパネル１を折りたたんだ状態を示したものである。該ヒンジ部４の屈曲方向の断面二次モーメントは該溝裏凸部６がえぐられたことにより激減しており、切断前と比べて該ヒンジ部４の屈曲性は格段に向上している。 FIG. 7 shows a state in which the folding panel 1 according to the present invention is folded. The cross-sectional secondary moment in the bending direction of the hinge portion 4 is drastically reduced by the removal of the groove back convex portion 6, and the flexibility of the hinge portion 4 is remarkably improved as compared with that before cutting.
尚、上記実施例では該折り畳みパネル１が開いた状態で該溝裏凸部６をえぐった例を示したが、該折り畳みパネル１を折りたたんだ状態で該溝裏凸部６をえぐってもよい。 In the above-described embodiment, an example in which the groove back convex portion 6 is gotten while the folding panel 1 is opened is shown. However, the groove back convex portion 6 may be gotten while the folding panel 1 is folded. .
また、該溝裏凸部６を余さず除去するようにえぐってもよい。 Further, the groove back convex portion 6 may be removed so as to be removed.
尚、前記えぐられ部２２とはヒンジ部４の表まで表裏貫通せず、図４に示すようにカットライン１１までしか溝裏凸部６をえぐらないものを指す。In addition, the said punching part 22 refers to what does not penetrate the front and back of the hinge part 4 but the groove back convex part 6 only to the cut line 11 as shown in FIG.
以上、実施例に示したように本発明によると、周溝３とヒンジ部４とが交差する位置における溝裏凸部６によって段差がついた該ヒンジ部４が、えぐられ部２２により段差を緩和ないし解消されているため、該ヒンジ部４の屈曲性を損なうことなく、見栄えの良い、表皮つきの折り畳みパネルを得ることができる。 As described above, according to the present invention as shown in the examples, the hinge portion 4 with a stepped by the groove Uratotsu portion 6 at a position where the circumferential groove 3 and the hinge portion 4 intersect, the step by gouged portion 22 Since it is alleviated or eliminated, it is possible to obtain a foldable panel with a good appearance without impairing the flexibility of the hinge portion 4.
