Description

【０００１】
【産業上の利用分野】
本発明は、建築物の内装壁、パーティション、扉などのパネル状の建築用中空成形品、自動車用中空成形品のようなプラスチック製中空構造のパネル状の布張り中空成形品に関する。
【０００２】
【従来の技術】
従来から、この種の中空成形品、特に、建築物の内装壁、パーティション、扉などのプラスチック製のパネル状の中空成形品は、そのパネルに意匠的効果をもたせるため、パネルの表面に装飾布を張ったものも用いられている。
【０００３】
また、中空構造のプラスチック中空体をブロー成形し、ブロー成形時に中空体の表面に織布を一体成形する方法も、特開平３−６９３３５号公報に記載されている。
【０００４】
【発明が解決しようとする課題】
ところで、表面に装飾布を張った中空体にあっては、その表面に張った装飾布の周辺部が、手などの当たりによって次第にめくれあがったり、装飾布の縁がほつれたり、あるいは毛足の長い装飾布の場合は周辺部の毛足が周縁部分からはみ出すなど、比較的短期間のうちに外観が損なわれやすいものである。
【０００５】
また、中空体のブロー成形時に装飾布を一体に成形する場合は、装飾布の毛足が長くなるほど周辺部の毛足がブロー過程で樹脂の移動に押されて、周辺方向になぎ倒される現象を呈し、装飾布をその周辺部まで外観良好に一体成形することが難しい。
【０００６】
本発明は、上記のような問題点を解消しようとするものであって、中空成形品の表面に張った装飾布の周辺部が剥がれたり、また、特に毛足の長い装飾布であっても長い毛足が周縁部分からはみ出すことがなく、外観性にすぐれたパネル状の布張り中空成形品を提供することを目的とする。
【０００７】
【課題を解決するための手段】
上記目的を達成するための本発明に係るパネル状の布張り中空成形品は、パネル状の成形品の意匠面をなす表面にその周縁部分より中空部側に低くした布張り面を形成して起毛部が成形品の表面側となるように装飾布を張り付け、上記周縁部分と布張り面との境に中空部側に窪む溝部を形成するとともに周縁部分を布張り面に対して突出して起毛部の毛足が周縁部分からはみ出さないようにする縁取部とし、この縁取部で囲まれた布張り面に張り付けた装飾布の周辺部の毛足が外方に倒れないように構成されていることを特徴とするものである。
【０００８】
【作用】
本発明に係る布張り中空成形品によれば、成形品の意匠面をなす表面にその周縁部分より中空部側に低くした布張り面を形成し、周縁部分と布張り面との境に中空部側に窪む溝部を形成して周縁部分を布張り面に対して突出する縁取部としており、その縁取部で囲まれた布張り面に装飾布を張り付けるので、布張り面に張り付けた装飾布の周縁部分は、その張り付け面より突出している縁取部により囲まれて保護される。
【０００９】
【実施例】
図１および図２は、本発明に係るパネル状の布張り中空成形品として、建築物の内壁やパーティションを構成するパネルを例示している。
【００１０】
図１および図２において、１はパネルであって、このパネル１は熱可塑性プラスチックをブロー成形したものである。パネル１は中空二重壁構造をなし、その表面に、その周縁部分より中空部側に低くした布張り面２を形成し、周縁部分と布張り面２との境に中空部側に窪む溝部３を形成して、周縁部分を布張り面２に対して突出する縁取部４としたものである。この縁取部４で囲まれた布張り面２には、装飾布５が張り付けられて、パネル１の表面が意匠面をなしている。６は中空部、７は装飾布５の基部、８はその起毛部である。
【００１１】
上記パネル１の表面において、布張り面２は周縁部分の縁取部４よりＨだけ中空部６側に低くなっており、溝部３はさらにｈだけ中空部６側に窪んでいる。そして、布張り面２の周縁と縁取部４との境には溝部３に相当する間隔９がとられており、布張り面２に張り付けた装飾布５の周辺部の毛足８ａがその間隔９内で自然に延びて、しかも縁取部４の立上り面によって外方への広がりが押さえられている。また、布張り面２は縁取部４より低く形成されているので、装飾布５の周辺部が縁取部４により保護される。このため、装飾布５の周辺部が剥がれたり、装飾布５の周辺部の毛足８ａが外方に倒れることがなく、長期間にわたってパネル１の意匠面の外観が良好に保たれる。
【００１２】
本発明に係るパネル１は、図３および図４に示すように、熱可塑性プラスチックのブロー成形により製造される。この図において、１０，１０は一対の分割形式の金型であり、その一方の金型１０には、パネルの意匠面をなす表面にその周縁部分より中空部側に低くした布張り面を成形するキャビティ１１と、周縁部分と布張り面１１との境に中空部側に窪む溝部を成形するキャビティ１２と、周縁部分に布張り面より突出する縁取部を成形するキャビティ１３を有している。
【００１３】
上記のように構成された一対の分割形式の金型１０，１０を用いてパネル１をブロー成形するにあたっては、一方の金型１０の布張り面を成形するキャビティ１１に装飾布５をその起毛部８がキャビティ側で基部７が表面側となるように嵌め込み状に装填する（図３参照）。次いで、開かれた一対の分割形式の金型１０，１０の間にパリスン１４を配置し、一対の分割形式の金型１０，１０を型締めして、パリスン１４内に圧力流体を導入すれば、パリスン１４は金型１０，１０のキャビティに沿った形状のパネルに成形されるとともに、その布張り面には一方の金型１０内に装填してあった装飾布５が、その基部７がパリスン１４に圧着され、一体に成形される（図４参照）。
【００１４】
ところで、図３に示す状態から図４に示す状態にパリスン１４がブロー成形される過程では、装飾布５の周辺部の樹脂が、内方に張り出している溝部を成形するキャビティ１２に沿って移動するので、樹脂の移動により装飾布５の周辺部の毛足８ａが移動する樹脂に押されることがない。このため、周辺部の毛足８ａがなぎ倒される現象を呈しないので、ブロー成形により、外観性にすぐれた布張り中空成形品が一体成形される。
【００１５】
【発明の効果】
本発明に係るパネル状の布張り中空成形品によれば、成形品の表面に張った装飾布の周辺部が剥がれたり、また、特に毛足の長い装飾布であっても長い繊維が周縁部分からはみ出すことがなく、外観性にすぐれたものが得られる。

[0003]
Japanese Patent Application Laid-Open No. 3-69335 discloses a method of blow molding a hollow plastic hollow body and integrally forming a woven fabric on the surface of the hollow body during blow molding.
[0004]
[Problems to be solved by the invention]
By the way, in the case of a hollow body with a decorative cloth on the surface, the peripheral part of the decorative cloth stretched on the surface gradually turns up due to a hit with a hand, the edge of the decorative cloth frays, In the case of a long decorative cloth, the appearance of the hair tends to be damaged within a relatively short period of time, such as the peripheral hairs protruding from the peripheral edge.
[0005]
In addition, when the decorative cloth is integrally molded during blow molding of the hollow body, the longer the bristle of the decorative cloth is, the longer the bristle of the peripheral part is pushed by the movement of the resin during the blowing process, and the phenomenon of tumbling in the peripheral direction is caused. It is difficult to integrally mold the decorative cloth up to its peripheral part with good appearance.
[0006]
The present invention is intended to solve the above-described problems, and the peripheral portion of the decorative cloth stretched on the surface of the hollow molded article is peeled off. An object of the present invention is to provide a panel-like upholstered hollow molded article having excellent appearance without causing long bristle legs to protrude from the peripheral portion.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a panel-like cloth-clad hollow molded product according to the present invention is formed by forming a cloth-clad surface lower on the hollow part side than the peripheral part on the surface forming the design surface of the panel-shaped molded product. A decorative cloth is pasted so that the raised portion is on the surface side of the molded product, and a groove is formed in the hollow portion at the boundary between the peripheral portion and the fabric surface, and the peripheral portion protrudes from the fabric surface. The brushed part of the raised part is designed to prevent it from protruding from the peripheral part, and it is configured so that the peripheral part of the decorative cloth affixed to the fabric surface surrounded by the border does not fall outward. It is characterized by that.
[0008]
[Action]
According to the cloth-reinforced hollow molded product according to the present invention, a cloth-reinforced surface is formed on the surface forming the design surface of the molded product so as to be lower on the hollow portion side than the peripheral portion, and the hollow is formed at the boundary between the peripheral portion and the cloth-reinforced surface. Grooves that are recessed on the part side are formed, and the peripheral part is an edged part that protrudes from the clothed surface. The decorative cloth is attached to the clothed surface surrounded by the edged part. The peripheral portion of the decorative cloth is protected by being surrounded by an edge portion protruding from the pasting surface.
[0009]
【Example】
FIG. 1 and FIG. 2 illustrate a panel constituting an inner wall or a partition of a building as a panel-like upholstered hollow molded product according to the present invention.
[0010]
1 and 2 , reference numeral 1 denotes a panel, which is a blow molded thermoplastic. The panel 1 has a hollow double-wall structure, and a cloth tension surface 2 is formed on the surface of the panel 1 so as to be lower on the hollow portion side than the peripheral edge portion, and is recessed toward the hollow portion at the boundary between the peripheral edge portion and the cloth tension surface 2. A groove portion 3 is formed, and a peripheral portion is formed as an edge portion 4 protruding from the cloth tension surface 2. A decorative cloth 5 is attached to the cloth tension surface 2 surrounded by the edging portion 4, and the surface of the panel 1 forms a design surface. 6 is a hollow portion, 7 is a base portion of the decorative cloth 5, and 8 is a raised portion thereof.
[0011]
On the surface of the panel 1, the upholstered surface 2 is lower than the peripheral edge portion 4 on the hollow portion 6 side by H, and the groove portion 3 is further recessed on the hollow portion 6 side by h. And the space | interval 9 equivalent to the groove part 3 is taken in the boundary of the periphery of the cloth tension surface 2, and the edge part 4, and the bristle foot 8a of the peripheral part of the decoration cloth 5 stuck on the cloth tension surface 2 is the space | interval. 9 is naturally extended, and the outward spread is suppressed by the rising surface of the edge portion 4. Further, since the cloth tension surface 2 is formed lower than the edge portion 4, the peripheral portion of the decorative cloth 5 is protected by the edge portion 4. For this reason, the peripheral part of the decorative cloth 5 does not peel off, and the bristle feet 8a in the peripheral part of the decorative cloth 5 do not fall outward, and the appearance of the design surface of the panel 1 is kept good for a long period of time.
[0012]
As shown in FIGS. 3 and 4, the panel 1 according to the present invention is manufactured by blow molding of a thermoplastic plastic. In this figure, reference numerals 10 and 10 denote a pair of divided molds, and one mold 10 is formed with a cloth-coated surface which is formed on the surface forming the design surface of the panel so as to be lower than the peripheral portion on the hollow portion side. And a cavity 12 for forming a groove recessed toward the hollow portion at the boundary between the peripheral edge portion and the cloth tension surface 11, and a cavity 13 for forming an edge portion protruding from the cloth tension surface at the peripheral edge portion. Yes.
[0013]
When the panel 1 is blow-molded by using the pair of divided molds 10 and 10 configured as described above, the decorative cloth 5 is raised in the cavity 11 for molding the cloth tension surface of one mold 10. It is loaded in a fitting manner so that the portion 8 is on the cavity side and the base portion 7 is on the surface side (see FIG. 3). Next, if the parison 14 is disposed between the pair of opened divided molds 10 and 10, the pair of divided molds 10 and 10 are clamped, and the pressure fluid is introduced into the parison 14. The Paris 14 is formed into a panel having a shape along the cavity of the molds 10 and 10, and the decorative cloth 5 loaded in one mold 10 is formed on the cloth tension surface, and the base portion 7 is formed. It is pressure-bonded to the Paris 14 and integrally molded (see FIG. 4).
[0014]
By the way, in the process in which the Paris 14 is blow-molded from the state shown in FIG. 3 to the state shown in FIG. 4, the resin around the decorative cloth 5 moves along the cavity 12 that molds the groove projecting inward. Therefore, the movement of the resin prevents the bristle feet 8a around the decorative cloth 5 from being pushed by the moving resin. For this reason, since the phenomenon that the bristle feet 8a in the peripheral portion are tumbled down is not exhibited, a cloth-reinforced hollow molded product having excellent appearance is integrally formed by blow molding.
[0015]
【The invention's effect】
According to the panel-shaped cloth-covered hollow molded product according to the present invention, the peripheral portion of the decorative fabric stretched on the surface of the molded product is peeled off, and even in the decorative fabric having a long bristle, a long fiber has a peripheral portion. A product with excellent appearance is obtained without protruding from the surface.
