Description

本発明は、対向設置された一対のガイドレールに沿ってスライド移動可能に配設されたシャッタに関するものである。 The present invention relates to a shutter disposed so as to be slidable along a pair of guide rails disposed opposite to each other.

例えば、図５に示すように、自動車の乗員室内に設置されるフロアコンソールＦＣでは、上方に開口した物品収納部１０２がコンソール本体１００の内部に画成されており、該物品収納部１０２の上部開口１０４を開閉する蓋部材としてシャッタＳ１を採用したものがある。前記シャッタＳ１は、フロアコンソールＦＣ内において物品収納部１０２を挟んで左右に対向して配設された一対のガイドレールＬ１,Ｌ２に、一端部に設けた摺動支持部７４および他端部に設けた摺動支持部７４を夫々係合させることで、該ガイドレールＬ１,Ｌ２に沿って前後方向のスライド移動が可能となっている。 For example, as shown in FIG. 5, in a floor console FC installed in a passenger compartment of an automobile, an article storage portion 102 opened upward is defined inside the console body 100, and an upper portion of the article storage portion 102 is formed. Some lid members that open and close the opening 104 employ a shutter S1. The shutter S1 is connected to a pair of guide rails L1 and L2 disposed on the floor console FC so as to be opposed to the left and right with the article storage portion 102 interposed therebetween. By engaging the provided sliding support portions 74 respectively, sliding movement in the front-rear direction is possible along the guide rails L1 and L2.

前記シャッタＳ１は、物品収納部１０２を閉じた状態ではコンソール本体１００の上面に略水平かつ平坦状に延在し、該物品収納部１０２を開いた状態では該コンソール本体１００の後側内部に湾曲状態で収納されるため、平坦状態と湾曲状態とに変形することが要求される。またシャッタＳ１は、物品収納部１０２を閉じた状態において、上面に物品や腕(肘)を載せたり、乗員室に乗降する際に手を着く等の使用態様が起こり得る。このためシャッタＳ１は、湾曲状態への変形を可能とする可撓性および荷重を支える剛性の両方を兼備する必要がある。そこで、従来のシャッタＳ１は、図６および図７に示すように、軟質樹脂(熱可塑性エラストマ等)により成形されたプレート部材６０と、この軟質樹脂より硬い硬質樹脂(ポリエチレンやポリプロピレン等)から成形されたリブ部材７０とを備えている。すなわち、従来のシャッタＳ１は、所謂多色成形方法により製造されて、硬さが異なる２種類以上の樹脂から形成されたものが多く採用されている。 The shutter S1 extends substantially horizontally and flatly on the upper surface of the console main body 100 when the article storage section 102 is closed, and is curved to the rear inside of the console main body 100 when the article storage section 102 is opened. Therefore, it is required to be deformed into a flat state and a curved state. Further, the shutter S1 may be used in a state where the article storage unit 102 is closed, such as placing an article or an arm (elbow) on the upper surface, or putting on a hand when getting in or out of the passenger compartment. For this reason, the shutter S1 needs to have both flexibility that enables deformation into a curved state and rigidity that supports a load. Therefore, as shown in FIGS. 6 and 7, the conventional shutter S1 is formed of a plate member 60 formed of a soft resin (thermoplastic elastomer or the like) and a hard resin (polyethylene, polypropylene or the like) harder than the soft resin. The rib member 70 is provided. That is, the conventional shutter S1 is often manufactured by a so-called multicolor molding method and formed of two or more kinds of resins having different hardnesses.

前記プレート部材６０は、セル部６２と該セル部６２より薄いヒンジ部６４とがスライド方向に交互に形成されており、各ヒンジ部６４において弾力的な湾曲変形が可能となっている。また、各リブ部材７０は、前記セル部６２に沿って延在するリブ部７２と、該リブ部７２の一端部および他端部の夫々に設けた摺動支持部７４,７４とを備えている。各リブ部材７０は、スライド方向で互いに個々が分離しており、リブ部７２がプレート部材６０のセル部６２に接合され、各摺動支持部７４がプレート部材６０より側方へ延出している。従ってシャッタＳ１は、各リブ部材７０の各摺動支持部７４,７４を対応するガイドレールＬ１,Ｌ２の溝部１１４に係合させることで、該ガイドレールＬ１,Ｌ２に沿ったスライド移動が可能となる。このようなシャッタＳ１は、例えば特許文献１に開示されている。 In the plate member 60, cell portions 62 and hinge portions 64 thinner than the cell portions 62 are alternately formed in the sliding direction, and each hinge portion 64 can be elastically deformed. Each rib member 70 includes a rib portion 72 extending along the cell portion 62 and sliding support portions 74 and 74 provided at one end portion and the other end portion of the rib portion 72, respectively. Yes. Each rib member 70 is separated from each other in the sliding direction, the rib portion 72 is joined to the cell portion 62 of the plate member 60, and each sliding support portion 74 extends laterally from the plate member 60. . Therefore, the shutter S1 can be slid along the guide rails L1 and L2 by engaging the sliding support portions 74 and 74 of the rib members 70 with the groove portions 114 of the corresponding guide rails L1 and L2. Become. Such a shutter S1 is disclosed in Patent Document 1, for example.

ところで、前記従来のシャッタＳ１では、軟質樹脂および該軟質樹脂より硬い硬質樹脂の２種類の成形材料を使用するので材料費が高くなると共に、軟質樹脂によるプレート部材６０の成形工程および硬質樹脂による各リブ部材７０の成形工程の２工程を経て製造するから成形作業工数が多くなり、これにより製造コストが嵩む難点がある。また、プレート部材６０と各リブ部材７０とは、異なる成形材料の接着力により接合されているから、シャッタＳ１の使用途中に両部材の接合部分で剥離するおそれもある。 By the way, in the conventional shutter S1, since two types of molding materials, that is, a soft resin and a hard resin harder than the soft resin, are used, the material cost becomes high, and the molding process of the plate member 60 by the soft resin and the hard resin each Since the rib member 70 is manufactured through two steps of the forming step, the number of forming work steps is increased, which increases the manufacturing cost. Moreover, since the plate member 60 and each rib member 70 are joined by the adhesive force of a different molding material, there exists a possibility that it may peel in the junction part of both members in the middle of use of shutter S1.

また各リブ部材７０は、２つの摺動支持部７４,７４がガイドレールＬ１,Ｌ２の溝部１１４に係合する形態であり、シャッタＳ１に厚み方向から荷重が加わった際には、図８(ａ)に示すように、両摺動支持部７４,７４の当接ポイントＰ１,Ｐ２を結ぶラインＢ１が単なる１本の直線となる２点支持の形態で該ガイドレールＬ１,Ｌ２に支持される。しかも両摺動支持部７４,７４の当接部７４Ａ,７４Ａは、ガイドレールＬ１,Ｌ２の溝部１１４との摩擦抵抗が減少するように球体状となっている。このため、前記ラインＢ１からスライド方向へずれた位置においてリブ部７２に荷重が加わった場合には、当該リブ部材７０は幅方向に延在する軸線を中心として回転変位してしまう。従って、図８(ｂ)に示すように、プレート部材６０のヒンジ部６４に荷重が加わった場合には、このヒンジ部６４に隣接する両リブ部材７０,７０が幅方向に延在する軸線を中心として逆に回転変位するようになり、ヒンジ部６４に応力が集中してプレート部材６０が該ヒンジ部６４で破断するおそれがある。 Each rib member 70 has a configuration in which the two sliding support portions 74 and 74 are engaged with the groove portions 114 of the guide rails L1 and L2, and when a load is applied to the shutter S1 from the thickness direction, FIG. As shown in a), the guide rails L1 and L2 support the line B1 connecting the contact points P1 and P2 of the sliding support portions 74 and 74 in a form of a two-point support in which the line B1 is a single straight line. . Moreover, the abutting portions 74A and 74A of the sliding support portions 74 and 74 are formed in a spherical shape so that the frictional resistance with the groove portions 114 of the guide rails L1 and L2 is reduced. For this reason, when a load is applied to the rib portion 72 at a position shifted in the sliding direction from the line B1, the rib member 70 is rotationally displaced about the axis extending in the width direction. Therefore, as shown in FIG. 8B, when a load is applied to the hinge portion 64 of the plate member 60, the axial line in which both rib members 70 and 70 adjacent to the hinge portion 64 extend in the width direction is used. There is a possibility that the plate member 60 may be broken at the hinge portion 64 due to the stress being concentrated on the hinge portion 64 due to the rotational displacement in the opposite direction as the center.

従って本発明では、安価で、荷重が加わることによる変形や破損を防止したシャッタを提供することを目的とする。 Accordingly, an object of the present invention is to provide a shutter that is inexpensive and prevents deformation and breakage due to application of a load.

前記課題を解決し、所期の目的を達成するため、本願の請求項１に記載の発明は、

隣り合う前記支持体部の間を繋ぐように設けられ、該支持体部より薄肉に形成することで可撓性を有するヒンジ部と、
前記各支持体部における前記ガイドレールに臨む各端部の夫々に前記スライド方向に並べて形成されて、該ガイドレールにスライド移動可能に係合する一対の当接部とを備え、
前記支持体部、ヒンジ部および当接部は、同一の成形材料から一体成形され、
各支持体部は、
前記ヒンジに連なる板部の裏面に両ガイドレールの対向方向に延在し、該対向方向の端部の夫々に前記当接部が形成される第１梁部と、
該板部の裏面に前記スライド方向において第１梁部と離間すると共に平行に延在し、前記対向方向の端部の夫々に前記当接部が形成される第２梁部と、
第１梁部および第２梁部の間に前記対向方向に間隔をあけて、該第１梁部および第２梁部に連なるように設けられた複数の連設部とを有し、
各支持体部は、前記第１梁部、前記第２梁部および前記連設部により剛性を有する構造体として構成されると共に、１つの支持体部に合計４つの当接部を形成したことを特徴とする。 In order to solve the above problems and achieve the intended purpose, the invention according to claim 1 of the present application provides:
A shutter disposed so as to be slidable along a pair of guide rails disposed opposite to each other,
A support portion that is provided side by side in the sliding direction and supports a load applied to the shutter;
A hinge part which is provided so as to connect between the adjacent support body parts, and has flexibility by being formed thinner than the support body part;
A pair of abutting portions that are formed side by side in the sliding direction on each of the end portions facing the guide rails in each of the support portions, and slidably engage with the guide rails,
The support part, the hinge part and the contact part are integrally molded from the same molding material,
Each support part is
A first beam portion extending in the opposing direction of both guide rails on the back surface of the plate portion connected to the hinge, and the abutting portion is formed at each of the end portions in the opposing direction;
A second beam portion that is spaced apart from and extends in parallel with the first beam portion in the sliding direction on the back surface of the plate portion, and the contact portion is formed at each of the end portions in the opposing direction;
A plurality of connecting portions provided so as to be connected to the first beam portion and the second beam portion with a space in the opposing direction between the first beam portion and the second beam portion ;
Each support portion is configured as a rigid structure by the first beam portion, the second beam portion, and the connecting portion, and a total of four contact portions are formed in one support portion. It is characterized by.

従って、請求項１に係る発明によれば、各支持体部は、シャッタに荷重が加わった際に、各端部の夫々にスライド方向に並べて２つずつ形成された計４つの各当接部で一対のガイドレールに支持されるため、シャッタの表側からの荷重により、該支持体部はスライド方向と直交する幅方向に延在する軸線を中心として回転変位することが防止される。すなわちシャッタは、各支持体部にシャッタの表側から荷重が加わった際に、該支持体部を繋ぐヒンジ部に応力が集中し難く、よって荷重を支持し得る各支持体部と同一材料で該支持体部より薄肉に形成して可撓性を有するヒンジ部を、該支持体部と一体的に設けることができる。すなわち、１種類の成形材料だけを使用して１工程でシャッタを一体成形し得るから、材料費が安くなると共に成形作業工数が削減されて製造コストを抑えることができ、該シャッタを安価に製造することが可能となる。また、シャッタが１種類の成形材料から一体成形されているので、部分的に剥離することもない。 Therefore, according to the first aspect of the present invention, each support portion is formed with a total of four abutment portions each formed in a row in the sliding direction on each end portion when a load is applied to the shutter. in order to be supported by a pair of guide rails, the load from the front side of the shutter, the support portion is being prevented for rotational displacement about an axis extending in the width direction perpendicular to the sliding direction. That is, when a load is applied to each support portion from the front side of the shutter, the stress is not easily concentrated on the hinge portion connecting the support portion, and therefore the shutter is made of the same material as each support portion that can support the load. A hinge portion that is thinner than the support portion and has flexibility can be provided integrally with the support portion. That is, since the shutter can be integrally formed in one process using only one type of molding material, the material cost can be reduced and the number of molding operations can be reduced, and the manufacturing cost can be reduced, and the shutter can be manufactured at low cost. It becomes possible to do. Further, since the shutter is integrally formed from one type of molding material, it is not partially peeled off.

請求項２に記載の発明は、前記各支持体部は、該支持体部におけるスライド方向の中央を挟んで配置された前記第１梁部および前記第２梁部の各端部に前記当接部が設けられることを要旨とする。
従って、請求項２に係る発明によれば、支持体部に対して、該支持体部におけるスライド方向の中央からずれた位置(中央よりヒンジ部に近い位置)に荷重が加わっても、当該支持体部は、スライド方向と直交する幅方向に延在する軸線を中心とした回転変位が起こり難い。 The invention according to claim 2, wherein each support section at each end of the first beam portion and the second beam portion which is disposed across the center of the sliding direction of the support portion prior to Kito The gist is that a contact portion is provided.
Therefore, according to the second aspect of the present invention, even if a load is applied to the support portion at a position shifted from the center of the support portion in the sliding direction (position closer to the hinge portion than the center), The body part is unlikely to undergo rotational displacement about an axis extending in the width direction orthogonal to the sliding direction.

請求項３に記載の発明は、前記支持体部は、前記第１梁部および前記第２梁部が前記ヒンジ部より裏側へ突出して設けられると共に、前記一対の当接部は該ヒンジ部より裏側に設けられ、
前記ヒンジ部は、該シャッタが平坦状態および湾曲状態に変形することを許容し、
前記ヒンジ部を挟んで隣り合う前記当接部は、該シャッタの平坦状態において、互いに相対する面が、該ヒンジ部から離れるにつれてスライド方向へ互いに離れるよう形成されることを要旨とする。
従って、請求項３に係る発明によれば、シャッタは、ヒンジ部の変形により平坦状態および湾曲状態に変形する。そして、ヒンジ部を挟んで隣り合う当接部は、シャッタの平坦状態において、互いに相対する面が該ヒンジ部から離れるにつれてスライド方向へ互いに離れるよう形成されるので、支持体部に設けた一対の当接部のスライド方向における間隔を大きく設定してもシャッタが湾曲状態に変形する際に接触せず、該シャッタが湾曲状態へ変形することを規制しない。また、支持体部に設けた一対の当接部のスライド方向における間隔を大きくできるので、シャッタの平坦状態において荷重が加わった際の支持体部の安定性を高めることができる。 According to a third aspect of the present invention, in the support portion , the first beam portion and the second beam portion are provided so as to protrude to the back side from the hinge portion, and the pair of contact portions are provided from the hinge portion. Provided on the back side,
The hinge unit may allow the said shutter is deformation in beauty bay song state Oyo flat state,
The contact portion adjacent to each other with the hinge portion, in a flat state of the shutter, opposing surfaces each other, and subject matter to be formed so as to away from each other as the sliding direction away from the hinge portion.
Therefore, according to the invention which concerns on Claim 3, a shutter deform | transforms into a flat state and a curved state by deformation | transformation of a hinge part. The contact portions adjacent to each other with the hinge portion interposed therebetween are formed so that the surfaces facing each other are separated from each other in the sliding direction as the distance from the hinge portion in the flat state of the shutter. Even if the distance between the contact portions in the sliding direction is set large, the shutter does not come into contact with the curved state, and the shutter is not restricted from being deformed into the curved state. Moreover, since the space | interval in the sliding direction of a pair of contact part provided in the support body part can be enlarged, the stability of a support body part when a load is added in the flat state of a shutter can be improved.

請求項４に記載の発明は、前記各支持体部は、前記第１梁部および前記第２梁部における前記スライド方向と直交する厚み方向の寸法が、前記一対のガイドレールの対向方向における両端部側で最小となり、該対向方向における中央部が両端部より大きくなっていることを要旨とする。

The gist is that it is the smallest on the part side, and the central part in the facing direction is larger than both end parts.
Therefore, according to the fourth aspect of the present invention, even when a load is applied to the support body portion, the support body portion becomes difficult to bend and deform in the thickness direction perpendicular to the sliding direction, and stress is concentrated on the hinge portion. It is prevented.

請求項５に記載の発明は、前記各当接部は、前記ガイドレールに当接する面が曲面状に形成されて、該ガイドレールに対し点接触するよう構成されたことを要旨とする。
従って、請求項５に係る発明によれば、各当接部はガイドレールと点接触するので、スライド方向に並べて設けた一対の当接部は常にスライド方向に離れた位置で当接するので、支持体部がガイドレールに対して安定的に支持される。また、各当接部とガイドレールとの摩擦抵抗が小さくなるので、軽い力でシャッタをスライド移動させることができ、該シャッタの開閉時の操作性を向上し得る。 The gist of the invention described in claim 5 is that each of the abutting portions is configured such that a surface abutting on the guide rail is formed in a curved surface and is in point contact with the guide rail.
Therefore, according to the fifth aspect of the present invention, since each contact portion is in point contact with the guide rail, the pair of contact portions arranged side by side in the slide direction always contacts at a position separated in the slide direction. The body part is stably supported with respect to the guide rail. Further, since the frictional resistance between each contact portion and the guide rail is reduced, the shutter can be slid with a light force, and the operability when opening and closing the shutter can be improved.

実施例のシャッタＳは、長さ方向に合計１８個の支持体部１０が並べて設けられており、幅方向において対称形状に形成されている。各支持体部１０は、図１(ａ)および図２(ｂ)に示すように、両ガイドレールＬ１,Ｌ２の間隔に適合する長さで、幅方向へ細長い形状でヒンジ部２０からシャッタＳの裏側へ突出した形状に形成されている。各支持体部１０は、シャッタＳの表側外板を構成する板部１２と、シャッタＳの幅方向へ延在する第１梁部１４と、該シャッタＳの長さ方向において第１梁部１４と離間しかつ平行に延在する第２梁部１６と、第１梁部１４および第２梁部１６を連設する複数の連設部１８とを備えている。各連設部１８は、第１梁部１４および第２梁部１６の間において幅方向へ所要間隔毎に配設され、これら第１梁部１４、第２梁部１６および各連設部１８からなる支持体部１０は、第１梁部１４と第２梁部１６との間に空間が画成された所謂梯子状のリブ構造体として構成されている。 The shutter S of the embodiment is provided with a total of 18 support portions 10 arranged in the length direction, and is formed in a symmetrical shape in the width direction. As shown in FIGS. 1 (a) and 2 (b), each support member 10 has a length suitable for the distance between the guide rails L1 and L2, and is elongated in the width direction from the hinge portion 20 to the shutter S. It is formed in the shape which protruded to the back side. Each support portion 10 includes a plate portion 12 constituting a front outer plate of the shutter S, a first beam portion 14 extending in the width direction of the shutter S, and a first beam portion 14 in the length direction of the shutter S. And a plurality of connecting portions 18 connecting the first beam portion 14 and the second beam portion 16 to each other. Each connecting portion 18 is disposed at a required interval in the width direction between the first beam portion 14 and the second beam portion 16, and the first beam portion 14, the second beam portion 16, and each connecting portion 18. The support body portion 10 is configured as a so-called ladder-like rib structure in which a space is defined between the first beam portion 14 and the second beam portion 16.

第１梁部１４および第２梁部１６は、図２(ｂ)および図３(ｂ)に示すように、シャッタＳの長さ方向において対称となる形状に形成されており、長さ方向における幅に対して厚み方向における高さが大きく設定されている。そして、第１梁部１４および第２梁部１６は、図１(ｂ)および図３(ｂ)に示すように、長さ方向における幅が、ヒンジ部２０側(外板１２側)が最大(Ｇ１)となっており、該ヒンジ部２０から離れるにつれて徐々に小さくなり、ヒンジ部２０と反対側の先端が最小(Ｇ２)となっている。また、第１梁部１４および第２梁部１６は、幅方向において４等分に便宜的に区切った場合に、中央寄りの２区分に対応する部分において高さが最大(Ｈ１)に形成され、当該支持体部１０の一端部１０Ａ側および他端部１０Ｂ側において高さが最小(Ｈ２)に形成されている。更に、第１梁部１４および第２梁部１６における一端部１０Ａ側の部分では、中央側から該一端部１０Ａに近づくにつれて高さが徐々に小さくなるように傾斜状に形成されていると共に、他端部１０Ｂ側の部分では、中央側から該他端部１０Ｂに近づくにつれて高さが徐々に小さくなるように傾斜状に形成されている。従って、第１梁部１４と第２梁部１６との間に空間が画成されたリブ構造体として構成された支持体部１０は、両梁部１４,１６間が硬質樹脂で埋まった形状の場合と同等の剛性が確保されており、幅方向における中間部に対して上方から荷重が加わっても、幅方向での撓み変形や捻れ変形が発現し難く構成されている。 As shown in FIGS. 2B and 3B, the first beam portion 14 and the second beam portion 16 are formed in a symmetrical shape in the length direction of the shutter S. The height in the thickness direction is set larger than the width. As shown in FIGS. 1B and 3B, the first beam portion 14 and the second beam portion 16 have a maximum width in the length direction on the hinge portion 20 side (outer plate 12 side). (G1), and gradually decreases with distance from the hinge portion 20, and the tip on the opposite side of the hinge portion 20 is the minimum (G2). In addition, when the first beam portion 14 and the second beam portion 16 are divided into four equal parts in the width direction for convenience, the height is maximum (H1) in the portion corresponding to the two sections closer to the center. The height of the support body 10 on the one end 10A side and the other end 10B side is minimized (H2). Further, the portion on the one end 10A side of the first beam portion 14 and the second beam portion 16 is formed in an inclined shape so that the height gradually decreases from the center side toward the one end portion 10A, The portion on the other end 10B side is formed in an inclined shape so that the height gradually decreases from the center side toward the other end 10B. Therefore, the support body portion 10 configured as a rib structure in which a space is defined between the first beam portion 14 and the second beam portion 16 has a shape in which the space between both the beam portions 14 and 16 is filled with a hard resin. In this case, rigidity equal to that in the above case is ensured, and even when a load is applied from above to the intermediate portion in the width direction, bending deformation and torsion deformation in the width direction are unlikely to occur.

そして、第１梁部１４および第２梁部１６からなる各支持体部１０は、図１(ｂ)および図３(ｂ)に示すように、長さ方向における幅が、ヒンジ部２０側(外板１２側)が最大(Ｗ１)となるように形成され、該ヒンジ部２０から離れるにつれて徐々に小さくなり、ヒンジ部２０と反対側の端部が最小(Ｗ２)となるように形成されている。すなわち支持体部１０は、シャッタＳの幅方向の外方から見た形状が、ヒンジ部２０から離れるにつれて先細となる台形形状をなし、シャッタＳの裏側へ突出して形成されている。 As shown in FIGS. 1 (b) and 3 (b), each support body portion 10 including the first beam portion 14 and the second beam portion 16 has a width in the length direction of the hinge portion 20 side ( The outer plate 12 side) is formed to have the maximum (W1), gradually decreases as the distance from the hinge portion 20, and the end opposite to the hinge portion 20 is formed to have the minimum (W2). Yes. That is, the support body portion 10 is formed in a trapezoidal shape in which the shape of the shutter S viewed from the outside in the width direction becomes tapered as the distance from the hinge portion 20 increases, and protrudes to the back side of the shutter S.

ヒンジ部２０は、図１〜図３に示すように、長さ方向で隣り合う支持体部１０,１０の板部１２と一体的に形成され、各支持体部１０を、厚み方向の表側に臨む部位で横並び状に連設している。そしてヒンジ部２０は、支持体部１０より薄肉に形成されて長さ方向で弾性的な撓曲変形または折曲変形が可能となっており、支持体部１０の表側から離間した裏側が近接して、隣り合う一方の支持体部１０における第１梁部１４と他方の支持体部１０における第２梁部１６とが接触するまで変形が可能となっている。ヒンジ部２０を挟んで隣り合う両支持体部１０,１０の間隔は、前述したように該支持体部１０が台形形状に形成されていることで、シャッタＳの平坦状態において、ヒンジ部２０側が最も狭く、該ヒンジ部２０から離れるにつれて徐々に大きくなっている。そしてヒンジ部２０は、厚みが０.５ｍｍ前後に設定されており、必要な剛性を有する硬質の合成樹脂からなる成形材料により形成されていても、隣り合う支持体部１０,１０が互いに接触するまで弾性的に撓曲変形または折曲変形し得ると共に、隣り合う支持体部１０,１０が互いに接触するまで折曲させた際でも塑性変形による破断が発生しないよう構成されている。 As shown in FIGS. 1 to 3, the hinge portion 20 is integrally formed with the plate portions 12 of the support portions 10 and 10 adjacent in the length direction, and each support portion 10 is placed on the front side in the thickness direction. It is arranged side by side at the part that faces. The hinge portion 20 is formed thinner than the support body portion 10 and can be elastically bent or bent in the length direction, and the back side separated from the front side of the support body portion 10 is close. Thus, the deformation can be performed until the first beam portion 14 in the adjacent one support portion 10 and the second beam portion 16 in the other support portion 10 come into contact with each other. As described above, the interval between the support portions 10 and 10 adjacent to each other across the hinge portion 20 is such that the support portion 10 is formed in a trapezoidal shape. It is the narrowest and gradually increases with distance from the hinge portion 20. The hinge portion 20 is set to have a thickness of about 0.5 mm, and even if the hinge portion 20 is formed of a molding material made of a hard synthetic resin having the necessary rigidity, the adjacent support portions 10 and 10 come into contact with each other. It can be elastically bent or bent to the extent that it does not break due to plastic deformation even when the adjacent support members 10 and 10 are bent until they come into contact with each other.

次に、各支持体部１０の幅方向の一端部１０Ａおよび他端部１０Ｂに設けた各摺動支持部３０について、図１〜図３を引用して説明する。なお、各支持体部１０の一端部１０Ａに設けた摺動支持部３０および他端部１０Ｂに設けた摺動支持部３０は、幅方向で対称形状に形成されているので、同一部位は同一符号を付して説明する。各摺動支持部３０は、厚み方向においてヒンジ部２０より裏側に設けられ、第１当接部３２と、この第１当接部３２に対し長さ方向に離間して設けた第２当接部３４とを備えている。各第１当接部３２は、支持体部１０における第１梁部１４の端部から水平に延出するように形成されて、幅方向において同一の軸線上に位置しており、第１梁部１４の端部に連設された腕部３２Ａと、該腕部３２Ａの先端に形成された当接突部３２Ｂとを備えている。当接突部３２Ｂは、図３(ａ)および図３(ｂ)に示すように、長さ方向から見た形状が該長さ方向に延在する軸線Ｊ２を中心とする円形に形成され、長さ方向の両端面が平面に形成されると共に、外周面が外方へ膨出する曲面状に形成されており、前記ガイドレールＬ１,Ｌ２の溝部１１４に突入可能な直径に形成されている。そして当接突部３２Ｂは、溝部１１４の底面１１４Ａ、上面１１４Ｂおよび側面１１４Ｃの夫々に、外周面が点接触し得るようになっている。なお腕部３２Ａは、縦断面形状が略矩形でかつ第１梁部１４との連設部では厚み方向のサイズが大きくなっており、該第１梁部１４に対して長さ方向および厚み方向の撓み変形が起こり難く構成されている。 Next, each sliding support part 30 provided in the one end part 10A and the other end part 10B in the width direction of each support body part 10 will be described with reference to FIGS. In addition, since the sliding support part 30 provided in the one end part 10A of each support part 10 and the sliding support part 30 provided in the other end part 10B are formed in the symmetrical shape in the width direction, the same site | part is the same A description will be given with reference numerals. Each sliding support portion 30 is provided on the back side of the hinge portion 20 in the thickness direction, and is provided with a first contact portion 32 and a second contact provided apart from the first contact portion 32 in the length direction. Part 34. Each first contact portion 32 is formed so as to extend horizontally from the end of the first beam portion 14 in the support body portion 10 and is located on the same axis in the width direction. The arm part 32A provided in a row at the end of the part 14 and the abutting protrusion 32B formed at the tip of the arm part 32A are provided. As shown in FIGS. 3A and 3B, the contact protrusion 32B is formed in a circular shape centered on the axis J2 extending in the length direction as seen from the length direction. Both end surfaces in the length direction are formed as flat surfaces, and the outer peripheral surface is formed in a curved shape that bulges outward, and is formed to have a diameter that can enter the groove portions 114 of the guide rails L1 and L2. . The contact protrusion 32B is configured such that the outer peripheral surface can make point contact with the bottom surface 114A, the top surface 114B, and the side surface 114C of the groove 114. Note that the arm portion 32A has a substantially rectangular longitudinal cross-sectional shape, and has a large size in the thickness direction at the continuous portion with the first beam portion 14, and the length direction and the thickness direction with respect to the first beam portion 14 The bending deformation is difficult to occur.

また、各摺動支持部３０の第２当接部３４は、第１当接部３２と長さ方向において対称となる形状に形成されて、第２梁部１６の端部に連設された腕部３４Ａと、該腕部３４Ａの先端に形成された当接突部３４Ｂとを備えている。各第２当接部３４は、支持体部１０における第２梁部１６の端部から水平に延出するように形成されて、幅方向において同一の軸線上に位置しており、第２梁部１６の端部に連設された腕部３４Ａと、該腕部３４Ａの先端に形成された当接突部３４Ｂとを備えている。当接突部３４Ｂは、図３(ａ)および図３(ｂ)に示すように、長さ方向から見た形状が該長さ方向に延在する軸線Ｊ２を中心とする円形に形成され、長さ方向の両端面が平面に形成されると共に、外周面が外方へ膨出する曲面状に形成されており、前記ガイドレールＬ１,Ｌ２の溝部１１４に突入可能な直径に形成されている。そして各当接突部３４Ｂは、溝部１１４の底面１１４Ａ、上面１１４Ｂおよび側面１１４Ｃの夫々に、外周面が点接触し得るようになっている。なお、第２当接部３４の腕部３４Ａは、縦断面形状が略矩形でかつ第２梁部１６との連設部では厚み方向のサイズが大きくなっており、該第２梁部１６に対して長さ方向および厚み方向の撓み変形が起こり難く構成されている。 Further, the second abutting portion 34 of each sliding support portion 30 is formed in a shape that is symmetrical with the first abutting portion 32 in the length direction, and is continuously provided at the end of the second beam portion 16. The arm part 34A is provided with the contact protrusion 34B formed in the front-end | tip of this arm part 34A. Each of the second contact portions 34 is formed so as to extend horizontally from the end of the second beam portion 16 in the support body portion 10 and is positioned on the same axis in the width direction. The arm part 34A provided continuously with the end part of the part 16 and the contact protrusion 34B formed at the tip of the arm part 34A are provided. As shown in FIGS. 3A and 3B, the contact protrusion 34B is formed in a circular shape centered on an axis J2 extending in the length direction when viewed from the length direction. Both end surfaces in the length direction are formed as flat surfaces, and the outer peripheral surface is formed in a curved shape that bulges outward, and is formed to have a diameter that can enter the groove portions 114 of the guide rails L1 and L2. . Each of the contact protrusions 34B can be brought into point contact with the outer peripheral surface of each of the bottom surface 114A, the top surface 114B, and the side surface 114C of the groove 114. Note that the arm portion 34A of the second contact portion 34 has a substantially rectangular longitudinal cross-sectional shape, and has a large size in the thickness direction at the continuous portion with the second beam portion 16. On the other hand, bending deformation in the length direction and the thickness direction hardly occurs.

そして各摺動支持部３０は、図３(ｂ)に示すように、該摺動支持部３０が形成された支持体部１０の台形形状に合わせて、前記ヒンジ部２０側より該ヒンジ部２０と離れた側が先細となる形状に形成されている。すなわち、摺動支持部３０の第１当接部３２は、第２当接部３４と反対側の端面におけるヒンジ部２０から離れた部位が、支持体部１０の第１梁部１４の傾斜した外壁に合わせて傾斜状に形成されている。同様に、摺動支持部３０の第２当接部３４は、第１当接部３２と反対側の端面におけるヒンジ部２０から離れた部位が、支持体部１０の第２梁部１６の傾斜した外壁に合わせて傾斜状に形成されている。これにより、隣り合う一方の支持体部１０に設けた摺動支持部３０の第１当接部３２と他方の支持体部１０に設けた摺動支持部３０の第２当接部３４との間隔は、シャッタＳの平坦状態において、ヒンジ部２０側より該ヒンジ部２０から離れた側が大きくなっている。従って、各摺動支持部３０において第１当接部３２と第２当接部３４との長さ方向での間隔を大きく設定しても、ヒンジ部２０の弾性的な変形により隣り合う支持体部１０,１０が近接するように姿勢変位する際に、隣り合う摺動支持部３０,３０の第１当接部３２と第２当接部３４とが接触することが防止されるよう構成されている。 Then, as shown in FIG. 3B, each sliding support portion 30 is adapted to the trapezoidal shape of the support body portion 10 on which the sliding support portion 30 is formed, from the hinge portion 20 side to the hinge portion 20. It is formed in a shape in which the side away from is tapered. That is, the first abutting portion 32 of the sliding support portion 30 is inclined at the first beam portion 14 of the supporting body portion 10 at a portion away from the hinge portion 20 on the end surface opposite to the second abutting portion 34. It is formed in an inclined shape according to the outer wall. Similarly, the second abutting portion 34 of the sliding support portion 30 is located at a position away from the hinge portion 20 on the end surface opposite to the first abutting portion 32, and the inclination of the second beam portion 16 of the supporting body portion 10. It is formed in an inclined shape to match the outer wall. Thereby, the first contact part 32 of the sliding support part 30 provided on one adjacent support part 10 and the second contact part 34 of the sliding support part 30 provided on the other support part 10 are arranged. The interval is larger on the side away from the hinge part 20 than on the hinge part 20 side in the flat state of the shutter S. Therefore, even if the distance in the length direction between the first contact portion 32 and the second contact portion 34 is set to be large in each sliding support portion 30, adjacent support bodies due to elastic deformation of the hinge portion 20. When the postures are displaced so that the parts 10 and 10 are close to each other, the first contact part 32 and the second contact part 34 of the adjacent sliding support parts 30 and 30 are prevented from contacting each other. ing.

そして、一端部１０Ａおよび他端部１０Ｂの両端部に摺動支持部３０,３０を備えた各支持体部１０は、図３(ａ)および図３(ｂ)に示すように、一方の摺動支持部３０の第１当接部３２および第２当接部３４と他方の摺動支持部３０の第１当接部３２および第２当接部３４との４つの当接部による４点支持態様により、一対のガイドレールＬ１,Ｌ２に支持される。すなわち、一方の摺動支持部３０の各当接部３２,３４が一方のガイドレールＬ１における溝部１１４の底面１１４Ａに当接する当接ポイントＰ１,Ｐ２と、他方の摺動支持部３０の各当接部３２,３４が他方のガイドレールＬ２における溝部１１４の底面１１４Ａに当接する当接ポイントＰ３,Ｐ４とは、四角形に延在するラインＢを形成する関係となっている。 Each support body portion 10 provided with the sliding support portions 30 and 30 at both ends of the one end portion 10A and the other end portion 10B has one sliding portion as shown in FIGS. 3 (a) and 3 (b). Four points by four contact portions of the first contact portion 32 and the second contact portion 34 of the moving support portion 30 and the first contact portion 32 and the second contact portion 34 of the other sliding support portion 30. It is supported by a pair of guide rails L1 and L2 by a support mode. That is, the contact points P1 and P2 at which the contact portions 32 and 34 of the one slide support portion 30 contact the bottom surface 114A of the groove 114 in the one guide rail L1 and the contact points P1 and P2 of the other slide support portion 30 respectively. The contact points P3 and P4 at which the contact portions 32 and 34 contact the bottom surface 114A of the groove 114 in the other guide rail L2 are in a relationship of forming a line B extending in a quadrilateral shape.

従って各支持体部１０は、板部１２に対して厚み方向から荷重が加わった際に、各摺動支持部３０における各第１当接部３２および各第２当接部３４の４つが一対のガイドレールＬ１,Ｌ２に当接することで、幅方向に延在する軸線Ｊ１を中心とした回転変位が規制されて安定的に支持される構造となっている。なお、各摺動支持部３０の各第１当接部３２および各第２当接部３４の計４つのうちの少なくとも３つ以上の当接部が一対のガイドレールＬ１,Ｌ２に当接すれば、支持体部１０は回転変位することが規制されて安定的に支持される。 Therefore, each support member 10 has a pair of four first contact portions 32 and second contact portions 34 in each slide support portion 30 when a load is applied to the plate portion 12 from the thickness direction. By being in contact with the guide rails L1 and L2, the rotational displacement about the axis line J1 extending in the width direction is regulated and stably supported. In addition, if at least three or more of the four abutment portions of the first abutment portions 32 and the second abutment portions 34 of the slide support portions 30 abut on the pair of guide rails L1 and L2, respectively. The support body portion 10 is stably supported by being restricted from rotational displacement.

実施例のシャッタＳでは、フロアコンソールＦＣの前側となる支持体部１０の板部１２に、該支持体部１０の長さ方向の寸法と略同じ寸法で幅方向に延在して上方へ突出する把持部４６が設けられている。従って、把持部４６を指先で把持することで、シャッタＳのスライド操作を簡易に行ない得る。 In the shutter S of the embodiment, the plate portion 12 of the support body portion 10 on the front side of the floor console FC extends in the width direction with substantially the same dimension as the length direction of the support body portion 10 and protrudes upward. A gripping portion 46 is provided. Therefore, the sliding operation of the shutter S can be easily performed by holding the holding part 46 with the fingertip.

前述のように構成された実施例のシャッタＳは、各支持体部１０の一端部１０Ａに設けた各摺動支持部３０の第１当接部３２および第２当接部３４を、コンソール本体１００に設けた一方のガイドレールＬ１の溝部１１４に各々突入して係合させると共に、各支持体部１０の他端部１０Ｂに設けた各摺動支持部３０の第１当接部３２および第２当接部３４を、他方のガイドレールＬ２の溝部１１４に各々突入して係合させることで、スライド移動が可能にコンソール本体１００に配設される。そしてシャッタＳは、物品収納部１０２の上部開口１０４に臨ませるようにコンソール本体１００の前方向へスライド移動させると、各支持体部１０の摺動支持部３０,３０が各ガイドレールＬ１,Ｌ２の直線部１１０に位置するようになり、一枚の平板の如く平坦状態となって上部開口１０４を全体的に覆蓋する(図４参照)。 In the shutter S of the embodiment configured as described above, the first contact portion 32 and the second contact portion 34 of each sliding support portion 30 provided at one end portion 10A of each support portion 10 are connected to the console body. The first abutting portion 32 and the first abutting portion 32 of each sliding support portion 30 provided at the other end portion 10B of each support body portion 10 and the groove portions 114 of one guide rail L1 provided at 100 are respectively engaged with and engaged with each other. The two abutting portions 34 are respectively inserted into and engaged with the groove portions 114 of the other guide rail L2, so that they can be slid and disposed in the console main body 100. When the shutter S is slid in the forward direction of the console main body 100 so as to face the upper opening 104 of the article storage unit 102, the sliding support portions 30 and 30 of the support body portions 10 are moved to the guide rails L1 and L2. It is located in the straight line portion 110, becomes flat like a single flat plate, and covers the upper opening 104 as a whole (see FIG. 4).

そして、実施例のシャッタＳは、物品収納部１０２の上部開口１０４を全体的に覆蓋した平坦状態において、上方を向いている表側に物品や腕を載せたり手を着く等により上方から荷重が加わった際でも、平坦状態が適切に維持される。すなわち、上方からの荷重を受けた各支持体部１０では、一方の摺動支持部３０の第１当接部３２および第２当接部３４と他方の摺動支持部３０の第１当接部３２および第２当接部３４の計４つのうちの少なくとも３つ以上が各ガイドレールＬ１,Ｌ２における溝部１１４の底面１１４Ａに当接するようになり、回転変位することなく安定的に姿勢保持される。また各支持体部１０は、第１梁部１４、第２梁部１６および連設部１８からなるリブ構造体に構成されて剛性を有しているから、板部１２の上方から荷重が加わっても、幅方向での撓み変形および捻り変形が起こらない。 In the shutter S of the embodiment, in a flat state where the upper opening 104 of the article storage unit 102 is entirely covered, a load is applied from above by placing an article or an arm on the front side facing upward or putting on a hand. Even in this case, the flat state is properly maintained. That is, in each support body portion 10 that receives a load from above, the first contact portion 32 and the second contact portion 34 of one sliding support portion 30 and the first contact portion of the other sliding support portion 30. At least three of the total of the portion 32 and the second contact portion 34 come into contact with the bottom surface 114A of the groove 114 in each of the guide rails L1 and L2, and the posture is stably maintained without rotational displacement. The In addition, since each support body portion 10 is configured by a rib structure including the first beam portion 14, the second beam portion 16, and the connecting portion 18 and has rigidity, a load is applied from above the plate portion 12. However, the bending deformation and the twist deformation in the width direction do not occur.

一方、シャッタＳは、コンソール本体１００の後方に向けてスライド移動させると、長さ方向における後側の支持体部１０から各ガイドレールＬ１,Ｌ２の曲線部１１２に移動するようになる。支持体部１０が各ガイドレールＬ１,Ｌ２の曲線部１１２に移動すると、該支持体部１０に設けた各摺動支持部３０における第１当接部３２の当接突部３２Ｂおよび第２当接部３４の当接突部３４Ｂが、各ガイドレールＬ１,Ｌ２の溝部１１４の上面１１４Ｂに当接するようになる。これにより、各ガイドレールＬ１,Ｌ２の曲線部１１２に移動した隣り合う支持体部１０,１０は、両支持体部１０,１０間のヒンジ部２０が弾性的に変形することで、一方の支持体部１０に対して他方の支持体部１０が姿勢変位する。そしてシャッタＳは、各ヒンジ部２０が弾性的に変形することで、各ガイドレールＬ１,Ｌ２の曲線部１１２の曲率と同じ曲率の湾曲状態に変形するようになる(図１(ｂ))。 On the other hand, when the shutter S is slid toward the rear of the console main body 100, the shutter S moves from the support portion 10 on the rear side in the length direction to the curved portions 112 of the guide rails L1 and L2. When the support body portion 10 moves to the curved portion 112 of each guide rail L1, L2, the contact protrusion 32B of the first contact portion 32 and the second contact portion 32 in each slide support portion 30 provided on the support body portion 10 are provided. The contact protrusion 34B of the contact portion 34 comes into contact with the upper surface 114B of the groove portion 114 of each guide rail L1, L2. Thereby, the adjacent support body parts 10 and 10 moved to the curved part 112 of each of the guide rails L1 and L2 are supported on one side by the elastic deformation of the hinge part 20 between the support body parts 10 and 10. The other support body 10 is displaced with respect to the body 10. The shutter S is deformed into a curved state having the same curvature as the curvature of the curved portion 112 of each guide rail L1, L2 by elastically deforming each hinge portion 20 (FIG. 1 (b)).

従って、実施例のシャッタＳでは、厚み方向から荷重が加わった際に、該シャッタＳを構成する各支持体部１０が、一端部１０Ａおよび他端部１０Ｂの夫々に設けた摺動支持部３０,３０における長さ方向に並べて２つずつ設けた各第１当接部３２および各第２当接部３４の計４つのうちの３つ以上で一対のガイドレールＬ１,Ｌ２に支持されるため、該支持体部１０は幅方向に延在する軸線Ｊ１を中心として回転変位することがない。しかも、摺動支持部３０の第１当接部３２および第２当接部３４が、支持体部１０における長さ方向の中央を挟んで一端部１０Ａおよび他端部１０Ｂに設けられているから、該支持体部１０に対してスライド方向の中央からずれた位置(中央よりヒンジ部２０に近い位置)に荷重が加わっても、当該支持体部１０は幅方向に延在する軸線Ｊ１を中心とした回転変位が起こり難い。すなわち、実施例のシャッタＳは、各支持体部１０に荷重が加わった際に、該支持体部１０を繋ぐヒンジ部２０に応力が集中し難く、よって該ヒンジ部２０を薄く形成することが可能となる。これによりヒンジ部２０は、支持体部１０および各摺動支持部３０を形成する成形材料と同一の成形材料で薄肉に形成しても可撓性を有することができるから、支持体部１０、ヒンジ部２０および摺動支持部３０を同一の硬質樹脂で一体成形することが可能となる。すなわちシャッタＳは、１種類の成形材料だけを使用して１工程でシャッタＳを一体成形し得るから、材料費が安くなると共に成形作業工数が削減されて製造コストを抑えることができ、安価に製造することが可能となる。 Therefore, in the shutter S of the embodiment, when a load is applied from the thickness direction, each support body portion 10 constituting the shutter S is provided with the sliding support portion 30 provided in each of the one end portion 10A and the other end portion 10B. , 30 are supported by the pair of guide rails L1, L2 by three or more of the total of four of the first abutment portions 32 and the second abutment portions 34 provided in a line in the length direction. The support portion 10 is not rotationally displaced about the axis J1 extending in the width direction. Moreover, the first contact portion 32 and the second contact portion 34 of the sliding support portion 30 are provided at the one end portion 10A and the other end portion 10B with the center in the length direction of the support body portion 10 interposed therebetween. Even when a load is applied to a position shifted from the center in the sliding direction with respect to the support 10 (position closer to the hinge 20 than the center), the support 10 is centered on the axis J1 extending in the width direction. Rotational displacement is unlikely to occur. That is, in the shutter S of the embodiment, when a load is applied to each support body portion 10, it is difficult for stress to concentrate on the hinge portions 20 that connect the support body portions 10, and thus the hinge portions 20 can be formed thin. It becomes possible. As a result, the hinge portion 20 can have flexibility even if it is formed thin with the same molding material as the molding material forming the support body portion 10 and each sliding support portion 30. The hinge part 20 and the sliding support part 30 can be integrally formed of the same hard resin. That is, since the shutter S can be formed integrally in one process using only one type of molding material, the material cost is reduced and the number of molding work steps can be reduced, and the manufacturing cost can be reduced. It can be manufactured.

そしてシャッタＳは、１種類の成形材料から一体成形されているので、支持体部１０とヒンジ部２０とが両部の境界部で剥離することがなく、また各支持体部１０と摺動支持部３０とが両部の境界部で剥離することがないから、剥離を原因として該シャッタＳが使用不能となることがない。 Since the shutter S is integrally formed from one type of molding material, the support body portion 10 and the hinge portion 20 are not peeled off at the boundary between the two portions, and each of the support body portions 10 is slidably supported. Since the part 30 does not peel off at the boundary part between the two parts, the shutter S is not disabled due to peeling.

また、隣り合う一方の支持体部１０に設けた摺動支持部３０の第１当接部３２と他方の支持体部１０に設けた摺動支持部３０の第２当接部３４のヒンジ部２０を挟んで互いに相対する面は、シャッタＳの平坦状態において、該ヒンジ部２０から離れるにつれてスライド方向へ互いに離れるように形成されている。従って、摺動支持部３０における第１当接部３２および第２当接部３４は、スライド方向における間隔を大きく設定してもシャッタＳが湾曲状態に変形する際に接触せず、該シャッタＳが湾曲状態へ変形することを規制しない。そして、摺動支持部３０における第１当接部３２および第２当接部３４のスライド方向における間隔を大きくできるので、シャッタＳの平坦状態において荷重が加わった際の支持体部１０の安定性を高めることができる。 Further, the first abutting portion 32 of the sliding support portion 30 provided on one adjacent support body portion 10 and the hinge portion of the second abutting portion 34 of the sliding support portion 30 provided on the other support portion 10. The surfaces opposed to each other across 20 are formed so as to be separated from each other in the sliding direction as the shutter S is separated in the flat state of the shutter S. Therefore, the first abutting portion 32 and the second abutting portion 34 in the sliding support portion 30 do not contact when the shutter S is deformed into a curved state even if the interval in the sliding direction is set large, and the shutter S Is not restricted from deforming into a curved state. And since the space | interval in the sliding direction of the 1st contact part 32 and the 2nd contact part 34 in the sliding support part 30 can be enlarged, the stability of the support body part 10 when a load is added in the flat state of the shutter S Can be increased.

また、各支持体部１０が、長さ方向に並ぶ第１梁部１４および第２梁部１６と両梁部１４,１６を繋ぐ連設部１８とによりリブ構造体として構成されているので、想定される荷重を受けても撓み変形および捻り変形が起きない剛性を得ることができる。特に、各支持体部１０の第１梁部１４および第２梁部１６は、幅方向の中央部分の高さを大きく設定してあるので、シャッタＳに厚み方向から加わった荷重を、撓み変形することなく適切に受けることができる。また、各支持体部１０は、長さ方向の寸法が、厚み方向でヒンジ部２０から離間するにつれて先細となる台形形状に形成されているから、該ヒンジ部２０の変形によるシャッタＳの湾曲状態への変形が規制されない。 In addition, since each support body portion 10 is configured as a rib structure by the first beam portion 14 and the second beam portion 16 arranged in the length direction and the connecting portion 18 that connects both the beam portions 14 and 16, Rigidity that does not cause bending deformation and torsional deformation even under an assumed load can be obtained. In particular, since the first beam portion 14 and the second beam portion 16 of each support body portion 10 are set to have a large height in the central portion in the width direction, the load applied to the shutter S from the thickness direction is flexibly deformed. You can receive it without having to. In addition, each support body portion 10 is formed in a trapezoidal shape in which the dimension in the length direction becomes tapered as it is separated from the hinge portion 20 in the thickness direction, and thus the curved state of the shutter S due to the deformation of the hinge portion 20. Deformation to is not regulated.

そして、各摺動支持部３０,３０の第１当接部３２および第２当接部３４と各ガイドレールＬ１,Ｌ２との摩擦抵抗が小さく抑えられているので、軽い力でシャッタＳをスライド移動させることができ、該シャッタＳの開閉時の操作性が向上している。 Since the frictional resistance between the first and second contact portions 32 and 34 of the slide support portions 30 and 30 and the guide rails L1 and L2 is kept small, the shutter S is slid with a light force. Therefore, the operability when the shutter S is opened and closed is improved.

また更に、各支持体部１０における第１梁部１４と第２梁部１６との間に空間が画成されるので、シャッタＳの軽量化が図られると共に、成形材料の使用量が少なくなって製造コストを抑え得る。しかも、成形時に成形材料が冷えることにより、シャッタＳの外面における支持体部１０に対応した部位に、成形ヒケが発生することも防止できる。 Furthermore, since a space is defined between the first beam portion 14 and the second beam portion 16 in each support body portion 10, the weight of the shutter S can be reduced and the amount of molding material used can be reduced. Manufacturing costs can be reduced. In addition, when the molding material cools during molding, it is possible to prevent molding sink marks from occurring in the portion corresponding to the support portion 10 on the outer surface of the shutter S.
