Description
本発明は、車両の荷室に設置されるラゲッジボード等として利用可能なパネルに関する。 The present invention relates to a panel that can be used as a luggage board or the like that is installed in the trunk of a vehicle.
特許文献１には、中空板に薄板状の鋼板を取り付けて構成されるパネル材が開示されている。 Patent document 1 discloses a panel material constructed by attaching a thin steel plate to a hollow plate.
特許文献１の構成では、鋼板と中空板の界面は、外力が加わりやすい位置に配置されており、界面に外力が加わると鋼板と中空板が剥離されてしまう虞がある。 In the configuration of Patent Document 1, the interface between the steel plate and the hollow plate is located in a position where it is easily subjected to external force, and there is a risk that the steel plate and the hollow plate will peel off if an external force is applied to the interface.
本発明はこのような事情に鑑みてなされたものであり、基材と面材の剥離が抑制される、パネルを提供するものである。 The present invention was made in consideration of these circumstances, and provides a panel in which peeling between the substrate and the face material is suppressed.
本発明によれば、基材と、面材を備えるパネルであって、前記面材は、前記基材に設けられた凹部内に固定される、パネルが提供される。 According to the present invention, a panel is provided that includes a base material and a facing material, the facing material being fixed in a recess provided in the base material.
本発明のパネルでは、基材に設けられた凹部内に面材が固定される。このため、基材と面材の界面が凹部内に配置されるので、界面に外力が加わりにくく、基材と面材が剥離することが抑制される。 In the panel of the present invention, the face material is fixed in a recess provided in the substrate. Therefore, the interface between the substrate and face material is located within the recess, making it difficult for external forces to be applied to the interface, and preventing the substrate and face material from peeling off.
以下、本発明の種々の実施形態を例示する。以下に示す実施形態は互いに組み合わせ可能である。
好ましくは、前記記載のパネルであって、前記基材及び前記面材は、表皮材で被覆される、パネルである。
好ましくは、前記記載のパネルであって、前記凹部の縁と前記基材の側端の間の周縁部の幅は、１～２０ｍｍである、パネルである。
好ましくは、前記記載のパネルであって、前記凹部の縁と前記面材の縁の間の段差をＳとし、前記面材の厚さをＴ１とすると、Ｓ／Ｔ１は、０．８以下である、パネルである。
Various embodiments of the present invention will be described below. The embodiments described below can be combined with each other.
Preferably, in the above-described panel, the base material and the face material are covered with a skin material.
Preferably, in the panel described above, the width of the peripheral edge between the edge of the recess and the side edge of the base is 1 to 20 mm.
Preferably, the panel is as described above, in which, when the step between the edge of the recess and the edge of the panel is S and the thickness of the panel is T1, S/T1 is 0.8 or less.
以下、本発明の実施形態について説明する。以下に示す実施形態中で示した各種特徴事項は、互いに組み合わせ可能である。また、各特徴事項について独立して発明が成立する。 The following describes the embodiments of the present invention. The various features shown in the following embodiments can be combined with each other. In addition, each feature can be an invention independently.
１．パネル１の構造
図１～図２に示すように、本発明の一実施形態に係るパネル１は、基材２と、面材３と、表皮材４を備える。パネル１は、略直方体形状であることが好ましい。パネル１は、車両の荷室に設置されるラゲッジボード等として利用可能である。
1 and 2, a panel 1 according to an embodiment of the present invention includes a base material 2, a face material 3, and a skin material 4. The panel 1 preferably has a substantially rectangular parallelepiped shape. The panel 1 can be used as a luggage board or the like to be installed in the trunk of a vehicle.
基材２は、好ましくは板状の部材である。基材２は、発泡体であっても非発泡体であってもよい。また、基材２は、中空体であっても中実体であってもよい。基材２は、金型を用いた成形によって形成することが好ましい。この場合、基材２をパネル１の製造前に予め所望の形状にすることができるので、取り扱い性に優れている。また、基材２を所望のパネル形状に合わせた形状にすることができるので、形状最適化された製品を得ることができる。 The substrate 2 is preferably a plate-shaped member. The substrate 2 may be a foamed or non-foamed body. The substrate 2 may also be a hollow or solid body. The substrate 2 is preferably formed by molding using a mold. In this case, the substrate 2 can be formed into a desired shape before the panel 1 is manufactured, and therefore has excellent handleability. In addition, the substrate 2 can be formed into a shape that matches the desired panel shape, and therefore a shape-optimized product can be obtained.
基材２の例としては、ビーズ発泡成形によって得られるビーズ発泡成形体、１枚の発泡又は非発泡の樹脂シートに凹凸形状を付与して得られる発泡又は非発泡シート成形体、発泡又は非発泡の、筒状パリソン又は２枚の樹脂シートを成形して得られる発泡又は非発泡中空成形体などが挙げられる。 Examples of the substrate 2 include a bead foam molded body obtained by bead foam molding, a foamed or non-foamed sheet molded body obtained by imparting a concave and convex shape to a single foamed or non-foamed resin sheet, and a foamed or non-foamed hollow molded body obtained by molding a foamed or non-foamed cylindrical parison or two resin sheets.
ビーズ発泡成形体は、例えば、発泡ポリスチレン、発泡アクリロニトリルスチレン、発泡ポリプロピレンなどで構成することができ、その発泡倍率は、例えば２０～５０倍であり、具体的には例えば、２０、２５、３０、３５、４０、４５、５０倍であり、ここで例示した数値の何れか２つの間の範囲内であってもよい。 The bead foam can be made of, for example, expanded polystyrene, expanded acrylonitrile styrene, expanded polypropylene, etc., and its expansion ratio is, for example, 20 to 50 times, specifically, for example, 20, 25, 30, 35, 40, 45, 50 times, or may be within a range between any two of the numerical values exemplified here.
発泡パリソン又は発泡樹脂シートは、ポリエチレンやポリプロピレンなどのポリオレフィンで構成することができ、これを用いた成形体の発泡倍率は、例えば１．１～８倍であり、具体的には例えば、１．１、１．５、２、３、４、５、６、７、８であり、ここで例示した数値の何れか２つの間の範囲内であってもよい。 The foamed parison or foamed resin sheet can be made of a polyolefin such as polyethylene or polypropylene, and the foaming ratio of a molded article using this is, for example, 1.1 to 8 times, specifically, for example, 1.1, 1.5, 2, 3, 4, 5, 6, 7, or 8, and may be within a range between any two of the numerical values exemplified here.
基材２の厚さは、例えば、５～２５ｍｍであり、８～２０ｍｍが好ましい。この厚さは、具体的には例えば、５、６、７、８、９、１０、１１、１２、１３、１４、１５、２０、２５ｍｍであり、ここで例示した数値の何れか２つの間の範囲内であってもよい。基材２の厚さは、基材２のおもて面２ｆと裏面２ｒの距離が最も大きくなる部位での距離を意味する。 The thickness of the substrate 2 is, for example, 5 to 25 mm, and preferably 8 to 20 mm. Specifically, the thickness may be, for example, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 20, or 25 mm, and may be within a range between any two of the numerical values exemplified here. The thickness of the substrate 2 refers to the distance at the portion where the distance between the front surface 2f and the back surface 2r of the substrate 2 is the greatest.
基材２には、凹部５が設けられている。凹部５は、基材２のおもて面２ｆと裏面２ｒに１つずつ設けられている。各凹部５内には、面材３が固定される。凹部５の平面形状（図１Ａの上方向から基材２を見たときの形状）は、略矩形状であることが好ましい。 The substrate 2 has recesses 5. One recess 5 is provided on the front surface 2f and one on the back surface 2r of the substrate 2. A surface material 3 is fixed in each recess 5. The planar shape of the recess 5 (the shape when the substrate 2 is viewed from above in FIG. 1A) is preferably approximately rectangular.
面材３は、板状の部材であり、凹部５内に面材３を固定することによって、パネル１の剛性を高めることができる。このため、基材２を薄厚化することができ、これによってパネル１の軽量化が可能になる。面材３は、単位厚さ当たりの剛性が基材２よりも高い材料で構成することができ、例えば、金属（アルミ、鉄など）や繊維強化樹脂などで構成可能である。面材３の厚さは、例えば、０．１～３ｍｍであり、０．３～１．５ｍｍが好ましい。この厚さは、例えば、具体的には例えば、０．１、０．２、０．３、０．４、０．５、０．６、０．７、０．８、０．９、１．０、１．５、２．０、２．５、３．０ｍｍであり、ここで例示した数値の何れか２つの間の範囲内であってもよい。なお、本明細書において、厚さ、深さ等の値は、別途明記しない限り、平均値を意味する。 The surface material 3 is a plate-like member, and by fixing the surface material 3 in the recess 5, the rigidity of the panel 1 can be increased. This allows the base material 2 to be made thinner, which allows the panel 1 to be made lighter. The surface material 3 can be made of a material having a higher rigidity per unit thickness than the base material 2, such as metal (aluminum, iron, etc.) or fiber-reinforced resin. The thickness of the surface material 3 is, for example, 0.1 to 3 mm, and preferably 0.3 to 1.5 mm. This thickness may be, for example, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.5, 2.0, 2.5, or 3.0 mm, or may be within a range between any two of the numerical values exemplified here. In this specification, values such as thickness and depth refer to average values unless otherwise specified.
面材３を凹部５内に固定する方法は、特に限定されず、基材２に溶着してもよく、接着層６を介して基材２に接着してもよい。接着層６を構成する接着剤としては、ウレタン系の接着剤やオレフィン系の接着剤が挙げられる。接着層６の厚さは、例えば、０．０１～０．５ｍｍであり、具体的には例えば、０．０１、０．０５、０．１、０．２、０．３、０．４、０．５ｍｍであり、ここで例示した数値の何れか２つの間の範囲内であってもよい。 The method for fixing the facing 3 in the recess 5 is not particularly limited, and it may be welded to the base material 2, or may be bonded to the base material 2 via an adhesive layer 6. Examples of adhesives that form the adhesive layer 6 include urethane-based adhesives and olefin-based adhesives. The thickness of the adhesive layer 6 is, for example, 0.01 to 0.5 mm, and more specifically, for example, 0.01, 0.05, 0.1, 0.2, 0.3, 0.4, or 0.5 mm, and may be within a range between any two of the numerical values exemplified here.
凹部５の底面５ｃの面積をＳ１とし、面材３の、凹部５の底面５ｃに対向する面の面積をＳ２とすると、Ｓ２／Ｓ１は、例えば、０．８～１であり、０．９～１が好ましい。この場合、凹部５のほぼ全体が面材３で充填されることとなり、パネル１の剛性が高くなる。Ｓ２／Ｓ１は、具体的には例えば、０．８０、０．８１、０．８２、０．８３、０．８４、０．８５、０．８６、０．８７、０．８８、０．８９、０．９０、０．９１、０．９２、０．９３、０．９４、０．９５、０．９６、０．９７、０．９８、０．９９、１．００であり、ここで例示した数値の何れか２つの間の範囲内であってもよい。 If the area of the bottom surface 5c of the recess 5 is S1 and the area of the surface of the facing material 3 facing the bottom surface 5c of the recess 5 is S2, then S2/S1 is, for example, 0.8 to 1, and preferably 0.9 to 1. In this case, the recess 5 is almost entirely filled with the facing material 3, increasing the rigidity of the panel 1. Specifically, S2/S1 is, for example, 0.80, 0.81, 0.82, 0.83, 0.84, 0.85, 0.86, 0.87, 0.88, 0.89, 0.90, 0.91, 0.92, 0.93, 0.94, 0.95, 0.96, 0.97, 0.98, 0.99, 1.00, and may be within a range between any two of the numerical values exemplified here.
凹部５の深さは、凹部５の縁５ａと面材３の縁３ａの間の段差が小さくなるように設定することが好ましく、段差が無いように設定することが好ましい。段差がある場合、縁５ａの方が高くても、縁３ａの方が高くてもよい。段差をＳとし、面材３の厚さをＴ１とすると、Ｓ／Ｔ１は、０．８以下が好ましい。この場合、凹部５を設けずに面材３を基材２上に配置した場合よりも段差が小さくなる。この値は、例えば０～０．８であり、具体的には例えば、０、０．１、０．２、０．３、０．４、０．５、０．６、０．７、０．８であり、ここで例示した数値の何れか２つの間の範囲内であってもよい。凹部５の深さは、面材３と接着層６の合計厚さに一致させることが好ましい。この場合、凹部５の縁５ａと面材３の縁３ａの間の段差を無くすことができる。 The depth of the recess 5 is preferably set so that the step between the edge 5a of the recess 5 and the edge 3a of the surface material 3 is small, and preferably set so that there is no step. If there is a step, the edge 5a may be higher or the edge 3a may be higher. If the step is S and the thickness of the surface material 3 is T1, S/T1 is preferably 0.8 or less. In this case, the step is smaller than when the surface material 3 is placed on the base material 2 without providing the recess 5. This value is, for example, 0 to 0.8, and specifically, for example, 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, and may be within a range between any two of the numerical values exemplified here. The depth of the recess 5 is preferably set to the same as the total thickness of the surface material 3 and the adhesive layer 6. In this case, the step between the edge 5a of the recess 5 and the edge 3a of the surface material 3 can be eliminated.
凹部５の深さは、例えば、０．１～３ｍｍであり、０．３～１．５ｍｍが好ましい。この深さは、例えば、具体的には例えば、０．１、０．２、０．３、０．４、０．５、０．６、０．７、０．８、０．９、１．０、１．５、２．０、２．５、３．０ｍｍであり、ここで例示した数値の何れか２つの間の範囲内であってもよい。 The depth of the recess 5 is, for example, 0.1 to 3 mm, and preferably 0.3 to 1.5 mm. This depth may be, for example, specifically, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.5, 2.0, 2.5, or 3.0 mm, or may be within a range between any two of the numerical values exemplified here.
基材２の厚さをＴとし、凹部５の深さをＤとすると、Ｄ／Ｔは、例えば、０．０１～０．３であり、０．０２～０．２が好ましい。この値は、具体的には例えば、０．０１、０．０２、０．０３、０．０４、０．０５、０．０６、０．０７、０．０８、０．０９、０．１、０．２、０．２、０．３であり、ここで例示した数値の何れか２つの間の範囲内であってもよい。 If the thickness of the substrate 2 is T and the depth of the recess 5 is D, then D/T is, for example, 0.01 to 0.3, and preferably 0.02 to 0.2. Specific examples of this value are 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.2, 0.2, and 0.3, and may be within a range between any two of the numerical values exemplified here.
凹部５の縁５ａと基材２の側端２ａの間の周縁部２ｂの幅Ｗは、１～２０ｍｍであることが好ましい。幅Ｗが小さすぎると周縁部２ｂの強度が弱すぎて外力によって周縁部２ｂが破壊される虞があり、幅Ｗが大きすぎると、面材３が存在してない領域が広くなりすぎて、パネル１の剛性が不十分になる場合がある。幅Ｗは、具体的には例えば、１、２、３、４、５、６、７、８、９、１０、１１、１２、１３、１４、１５、１６、１７、１８、１９、２０ｍｍであり、ここで例示した数値の何れか２つの間の範囲内であってもよい。周縁部２ｂの幅Ｗは、基材２の全周に渡って一定であることが好ましい。幅Ｗが全周に渡って一定でない場合、その平均値が上記範囲内であることが好ましく、その最小値と最大値の両方が上記範囲内であることがさらに好ましい。 The width W of the peripheral portion 2b between the edge 5a of the recess 5 and the side end 2a of the base material 2 is preferably 1 to 20 mm. If the width W is too small, the strength of the peripheral portion 2b is too weak and the peripheral portion 2b may be destroyed by an external force, and if the width W is too large, the area where the face material 3 is not present may be too wide, causing the rigidity of the panel 1 to be insufficient. Specifically, the width W may be, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 mm, or may be within a range between any two of the numerical values exemplified here. The width W of the peripheral portion 2b is preferably constant around the entire circumference of the base material 2. If the width W is not constant around the entire circumference, it is preferable that the average value is within the above range, and it is even more preferable that both the minimum and maximum values are within the above range.
表皮材４は、基材２及び面材３を被覆するように配置される。表皮材４は、基材２のおもて面２ｆの凹部５内に配置された面材３と、基材２のおもて面２ｆの周縁部２ｂと、基材２の側面２ｓを被覆することが好ましい。これによって、パネル１のおもて面１ｆと側面１ｓがユーザーに視認されやすい用途（例：ラゲッジボード）での美観が向上する。また、基材２と面材３の界面が表皮材４で被覆されるので、面材３が基材２から剥離することが抑制される。また、表皮材４は、基材２の裏面２ｒの凹部５内に配置された面材３の一部又は全部と、基材２の裏面２ｒの周縁部２ｂを被覆することが好ましい。これによって、基材２と、裏面２ｒ側の面材３の界面が表皮材４で被覆されるので、裏面２ｒ側の面材３が基材２から剥離することが抑制される。 The skin material 4 is arranged so as to cover the base material 2 and the face material 3. The skin material 4 preferably covers the face material 3 arranged in the recess 5 of the front surface 2f of the base material 2, the peripheral portion 2b of the front surface 2f of the base material 2, and the side surface 2s of the base material 2. This improves the aesthetics in applications where the front surface 1f and side surface 1s of the panel 1 are easily visible to the user (e.g. luggage board). In addition, since the interface between the base material 2 and the face material 3 is covered with the skin material 4, peeling of the face material 3 from the base material 2 is suppressed. In addition, the skin material 4 preferably covers a part or all of the face material 3 arranged in the recess 5 of the back surface 2r of the base material 2 and the peripheral portion 2b of the back surface 2r of the base material 2. As a result, the interface between the base material 2 and the face material 3 on the back surface 2r side is covered with the skin material 4, so peeling of the face material 3 on the back surface 2r side from the base material 2 is suppressed.
表皮材４は、一例では、不織布であり、接着層７を介して、面材３及び基材２に接着することができる。 In one example, the skin material 4 is a nonwoven fabric, and can be adhered to the face material 3 and the base material 2 via an adhesive layer 7.
２．パネル１の製造方法
パネル１は、以下の方法で製造することができる。
2. Method for Producing Panel 1 The panel 1 can be produced by the following method.
（１）基材準備工程
基材準備工程では、凹部５を有する基材２を準備する。
(1) Substrate Preparation Step In the substrate preparation step, the substrate 2 having the recess 5 is prepared.
（２）面材固定工程
面材固定工程では、基材２の凹部５内に面材３を固定する。面材３は、例えば溶着又は接着によって固定することができる。接着の場合、基材２と面材３の間に接着層を配置し、その後、面材３を凹部５の底面５ｃに押し付けることによって、面材３を凹部５の底面５ｃに固定することができる。接着層は、凹部５の底面５ｃ又は面材３に接着剤を塗布（例：スプレー塗布、ビード塗布）することによって配置することができる。
(2) Face Material Fixing Step In the face material fixing step, the face material 3 is fixed in the recess 5 of the substrate 2. The face material 3 can be fixed by, for example, welding or adhesion. In the case of adhesion, an adhesive layer is disposed between the substrate 2 and the face material 3, and then the face material 3 is pressed against the bottom surface 5c of the recess 5, thereby fixing the face material 3 to the bottom surface 5c of the recess 5. The adhesive layer can be disposed by applying (e.g., spray coating, bead coating) an adhesive to the bottom surface 5c of the recess 5 or the face material 3.
（３）表皮材固定工程
表皮材固定工程では、表皮材４を固定する部位（面材３及び基材２）に接着剤を塗布し、その後、接着剤を塗布した部位に表皮材４を押し付けることによって、表皮材４を面材３及び基材２に固定することができる。
(3) Skin Material Fixing Process In the skin material fixing process, adhesive is applied to the areas (face material 3 and base material 2) where the skin material 4 is to be fixed, and then the skin material 4 is pressed against the areas where the adhesive has been applied, thereby fixing the skin material 4 to the face material 3 and the base material 2.
３．パネル１の別の製造方法
「２．パネル１の製造方法」では、凹部５を有する基材２を準備した上で、凹部５内に面材３を固定したが、凹部５を有しない基材２を準備し、基材２上に面材３を載置した状態で面材３を基材２に押し付けることによって、面材３を基材２にめり込ませて、基材２に凹部５を形成してもよい。このような方法によっても、凹部５内に面材３を固定することができる。この場合、基材２は、押圧によって凹みやすい材質（例えば発泡体、特にビーズ発泡成形体）で構成することが好ましい。
3. Another manufacturing method of the panel 1 In "2. Manufacturing method of the panel 1", a base material 2 having a recess 5 is prepared, and then the face material 3 is fixed in the recess 5. However, a base material 2 without a recess 5 may be prepared, and the face material 3 is placed on the base material 2 and pressed against the base material 2 to cause the face material 3 to sink into the base material 2, thereby forming a recess 5 in the base material 2. This method also makes it possible to fix the face material 3 in the recess 5. In this case, the base material 2 is preferably made of a material that is easily recessed by pressure (for example, a foam, particularly a bead foam molded body).
面材３を基材２に押し付ける工程は、基材２と面材３の間に接着層を配置した状態で行ってもよく、接着層を配置していない状態で行ってもよい。後者の場合は、面材３を基材２に押し付けることによって凹部５を形成し、その後に、基材２と面材３の間に接着層を配置した状態で面材３を基材２に押し付けることによって、面材３を基材２に固定することができる。前者の方が、工程数が少なくなるので好ましい。この押し付けは、例えば、押圧ローラやプレス機などを用いて行うことができる。 The step of pressing the facing material 3 against the substrate 2 may be performed with or without an adhesive layer between the substrate 2 and the facing material 3. In the latter case, the facing material 3 is pressed against the substrate 2 to form the recess 5, and then the facing material 3 is pressed against the substrate 2 with an adhesive layer between the substrate 2 and the facing material 3, thereby fixing the facing material 3 to the substrate 2. The former is preferable since it requires fewer steps. This pressing can be performed using, for example, a pressure roller or a press machine.
本製造方法においては、表皮材固定工程は、「２．パネル１の製造方法」と同様に行うことができる。 In this manufacturing method, the skin fixing process can be carried out in the same manner as in "2. Manufacturing method of panel 1."
４．その他実施形態
・表皮材４は、不要な場合には省略可能である。
・凹部５は、基材２のおもて面２ｆと裏面２ｒの一方のみに設けてもよい。この場合、面材３は、凹部５がある面のみに配置される。
4. Other embodiments: The skin material 4 can be omitted if not required.
The recessed portion 5 may be provided on only one of the front surface 2f and the back surface 2r of the base material 2. In this case, the face material 3 is disposed only on the surface on which the recessed portion 5 is provided.
