Description

本発明は、ガラスサンルーフの内側に遮光用として取り付けるロールスクリーン式の自動車用サンシェード装置に関するものである。   The present invention relates to a roll screen type automobile sunshade device that is mounted inside a glass sunroof for light shielding.

引き出し自在に巻取装置に巻回された日除けスクリーンの前端に横バーを取り付けると共に、日除けスクリーンの左右両側方に1対のガイドレールを延設し、これら一対のガイドレールのそれぞれに横バーの各端を摺合させ、横バーをガイドレール上で進退させることによって日除けスクリーンを展開・収納するようにした自動車用サンシェード装置が知られている(特許文献1を参照されたい)。   A horizontal bar is attached to the front end of the awning screen that is wound around the winding device so that it can be pulled out, and a pair of guide rails are extended on both the left and right sides of the awning screen. 2. Description of the Related Art An automobile sunshade device is known in which each end is slid and a sunscreen is developed and stored by moving a horizontal bar forward and backward on a guide rail (see Patent Document 1).

特許文献1に記載のサンシェード装置においては、日除けスクリーンの引出方向に直交する向き(車幅方向)に延在する板ばね材などからなる芯材を適宜な前後方向間隔をおいて日除けスクリーンに縫い付けておき、展開した日除けスクリーンが車幅方向の垂直断面内において車体ルーフの内面に沿って湾曲するようにしている。
特公平7−90692号公報
In the sunshade device described in Patent Document 1, a core material made of a leaf spring material or the like extending in a direction (vehicle width direction) perpendicular to the drawing direction of the sunscreen is sewn to the sunscreen at an appropriate front-rear direction interval. In addition, the unfolded sunscreen is curved along the inner surface of the vehicle body roof in a vertical cross section in the vehicle width direction.
Japanese Patent Publication No. 7-90692

この従来のサンシェード装置によると、芯材は、巻取軸に巻き取られる日除けスクリーンと共に順に巻き込まれ、引き出される日除けスクリーンと共に順に繰り出されるようになっている。   According to this conventional sunshade apparatus, the core material is sequentially wound together with the awning screen wound around the winding shaft, and is sequentially fed out together with the awning screen pulled out.

他方、車体ルーフの内面は、車体前後方向の垂直断面内でも中央が上向きに凸となるように湾曲しているので、この湾曲に沿って日除けスクリーンが展開するように、ガイドレールに適宜な曲率を付しておき、日除けスクリーンの側端がガイドレールで規制されるようにすると良い。   On the other hand, the inner surface of the vehicle body roof is curved so that the center is convex upward even in a vertical cross section in the longitudinal direction of the vehicle body, so that the guide rail has an appropriate curvature so that the sunscreen is developed along this curve. It is recommended that the side edge of the sunscreen be regulated by the guide rail.

しかるに、日除けスクリーンの側端部がガイドレールに摺接するように構成すると、展開する日除けスクリーンと共に繰り出される芯材の取付部がガイドレールに当接し、その時に打音を発生することが考えられる。このような打音の発生は、商品の高級感を著しく阻害するので好ましいことではない。   However, if the side portion of the awning screen is configured to be in sliding contact with the guide rail, it is conceivable that the attachment portion of the core member fed together with the unfolded awning screen comes into contact with the guide rail and generates a hitting sound at that time. Generation of such a hitting sound is not preferable because it significantly impairs the high-quality feeling of the product.

本発明は、このような従来技術の不都合を解消すべく案出されたものであり、その主な目的は、展開した日除けスクリーンがばたつくことがなく、しかも展開する際に異音を発することがないように改良された自動車用サンシェード装置を提供することある。   The present invention has been devised to eliminate such disadvantages of the prior art, and its main purpose is that the developed awning screen does not flutter, and that it generates noise when deployed. There is a need to provide an automotive sunshade device that is improved so that there is no such problem.

このような課題を解決するために本発明の請求項1は、引き出し自在に巻取装置3に巻回されると共にその前端に横バー8が取り付けられ且つ引き出し方向に直交する向きに延在する略線状のばね部材13を備えたスクリーン2と、横バーの各端を摺合させるべくスクリーンの左右両側方に延設された1対のガイドレール4とを有し、横バーを進退駆動することによってスクリーンを展開・収納するようにした自動車用サンシェード装置において、展開するスクリーンの側端部下面が摺接する軟質弾性材からなる支持部14をガイドレールの上面に設けたことを特徴とするものとした。   In order to solve such a problem, the first aspect of the present invention is wound around the winding device 3 so that it can be pulled out, and a horizontal bar 8 is attached to the front end thereof and extends in a direction perpendicular to the pulling direction. The screen 2 having a substantially linear spring member 13 and a pair of guide rails 4 extending on both the left and right sides of the screen so as to slide the ends of the horizontal bar are driven to advance and retract the horizontal bar. A sunshade device for an automobile in which the screen is developed and stored by providing a support portion 14 made of a soft elastic material in which the lower surface of the side end portion of the developing screen is in sliding contact with the upper surface of the guide rail. It was.

このような本発明によれば、展開するスクリーンの左右両側端を支持部に摺接させることにより、展開時のスクリーンに車体ルーフ内面に沿う曲率を付与することができ、しかも軟質弾性材からなる支持部に線状のばね部材の取付部が当接するので、スクリーンが展開する際に打音を発生せずに済む。   According to the present invention as described above, the left and right ends of the screen to be deployed are brought into sliding contact with the support portion, whereby a curvature along the inner surface of the vehicle body roof can be given to the screen at the time of deployment, and it is made of a soft elastic material. Since the attachment portion of the linear spring member comes into contact with the support portion, it is not necessary to generate a hitting sound when the screen is deployed.

以下に添付の図面を参照して本発明について詳細に説明する。なお、ロールスクリーン式サンシェード装置自体は文献1に記載されている通り既に周知のものなので、巻取機構や車体との関係についての詳細な説明はここでは省略する。   Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Since the roll screen sunshade device itself is already known as described in Document 1, a detailed description of the relationship with the winding mechanism and the vehicle body is omitted here.

図1・2は、本発明が適用された自動車用サンシェード装置の要部を示している。このサンシェード装置1は、柔軟なシート材により形成された日除けスクリーン2が巻回される巻取装置3と、日除けスクリーン2の開閉運動を案内すべく車体前後方向に延設された左右一対のガイドレール4とからなっている。   FIGS. 1 and 2 show a main part of an automobile sunshade device to which the present invention is applied. The sunshade device 1 includes a winding device 3 around which a awning screen 2 formed of a flexible sheet material is wound, and a pair of left and right guides extending in the longitudinal direction of the vehicle body to guide the opening and closing movement of the awning screen 2. It consists of rails 4.

巻取装置3は、巻取軸5と、この巻取軸5の両端を支持するホルダ6と、これらのホルダ6をその両端に保持するケーシング7とにより構成されており、巻取軸5は、図示しないコイルばねによって日除けスクリーン2を巻取る方向に常時回転付勢されている。   The winding device 3 includes a winding shaft 5, a holder 6 that supports both ends of the winding shaft 5, and a casing 7 that holds these holders 6 at both ends. Rotation is always urged in a direction to wind up the awning screen 2 by a coil spring (not shown).

日除けスクリーン2の前端には、アルミニウム合金の押出材からなる横バー8が結合されている。この横バー8の左右両端には、アルミニウム合金の押出材で形成されたガイドレール4のガイド溝9に摺合したスライドシュー10が結合されている。   A front bar of the awning screen 2 is joined with a horizontal bar 8 made of an aluminum alloy extruded material. A slide shoe 10 slidably engaged with a guide groove 9 of a guide rail 4 formed of an extruded material of an aluminum alloy is coupled to both left and right ends of the horizontal bar 8.

スライドシュー10には、ガイドレール4に設けられた縦断面形状がC字形をなすケーブルガイド11内に挿通された公知のプッシュプルケーブル12の端末が結合されており、図示されない電動駆動機構から与えられる軸力によってプッシュプルケーブル12を押し引き駆動することにより、日除けスクリーン2の前端に結合された横バー8を車体前後方向に進退移動させることができるようになっている。   A terminal of a known push-pull cable 12 inserted in a cable guide 11 having a longitudinal cross-sectional shape provided on the guide rail 4 and having a C-shape is coupled to the slide shoe 10 and is supplied from an electric drive mechanism (not shown). By pushing and pulling the push-pull cable 12 with the generated axial force, the horizontal bar 8 coupled to the front end of the sunscreen 2 can be moved back and forth in the longitudinal direction of the vehicle body.

このような構成により、日除けスクリーン2を展開させる際には、プッシュプルケーブル12の押し出し動作によって横バー8を前進させることにより、コイルばねの付勢力に抗して日除けスクリーン2が引き出される。この逆に日除けスクリーン2を収納する際には、プッシュプルケーブル12の引き込み動作によって横バー8を後退させることにより、コイルばねで付勢された巻取軸5が回転して日除けスクリーン2が巻き取られる。また、全閉位置と全開位置との間の任意の中間位置で電動駆動機構を停止することにより、日除けスクリーン2を静止させることができ、いずれの位置でもコイルばねの付勢力が日除けスクリーン2に作用するため、日除けスクリーン2の緊張状態が常に維持される。   With such a configuration, when the awning screen 2 is deployed, the awning screen 2 is pulled out against the urging force of the coil spring by advancing the horizontal bar 8 by pushing out the push-pull cable 12. On the contrary, when storing the awning screen 2, the retracting bar 5 is retracted by the pull-in operation of the push-pull cable 12, whereby the winding shaft 5 urged by the coil spring rotates to wind the awning screen 2. Taken. Further, by stopping the electric drive mechanism at an arbitrary intermediate position between the fully closed position and the fully open position, the awning screen 2 can be stopped, and the urging force of the coil spring is applied to the awning screen 2 at any position. In order to act, the tension state of the awning screen 2 is always maintained.

日除けスクリーン2には、車体ルーフの内面における車幅方向の垂直断面内での湾曲面に沿う湾曲面を展開状態において付与するように、自由状態時に中央が上向きに凸となるように湾曲する棒状のばね部材13が、日除けスクリーン2の展開時に上方を向く面に、引出し方向に対して直交する方向に延設されている。このばね部材13は、日除けスクリーン2の引出し方向について適宜な間隔をおいて複数設けられており、収納時には日除けスクリーン2に巻き込まれて直線状に弾性変形されて巻取られるようになっている。   The awning screen 2 has a rod-like shape that is curved so that the center is convex upward in a free state so that a curved surface along a curved surface in a vertical cross section in the vehicle width direction on the inner surface of the vehicle body roof is provided in a deployed state. The spring member 13 is extended in a direction perpendicular to the pull-out direction on the surface facing upward when the sunscreen 2 is deployed. A plurality of the spring members 13 are provided at an appropriate interval in the drawing direction of the awning screen 2 and are wound around the awning screen 2 and elastically deformed in a straight line when retracted.

ガイドレール4は、車体ルーフの内面における車体前後方向の垂直断面内での湾曲面に対応した曲率で緩く湾曲させられており、この湾曲に沿って日除けスクリーン2が展開するように、日除けスクリーン2の左右側端縁の下面に当接する支持部材14が、ガイドレール4における日除けスクリーン2の左右側端縁部に対応する部分に設けられている。この支持部材14は、軟質材(例えばEPDM)にて中空に形成されると共に、ガイドレール4に一体形成された取付溝15に結合しており、その上面にシリコン剤がコーティングされている。この支持部材14により、日除けスクリーン2の左右両側端の高さ位置が規定されている。   The guide rail 4 is gently curved with a curvature corresponding to the curved surface in the vertical cross section in the longitudinal direction of the vehicle body on the inner surface of the vehicle body roof, and the sunscreen 2 is developed so that the sunscreen 2 is developed along this curve. A support member 14 that abuts the lower surface of the left and right side edges is provided at a portion of the guide rail 4 corresponding to the left and right edges of the awning screen 2. The support member 14 is formed of a soft material (for example, EPDM) and is coupled to a mounting groove 15 integrally formed with the guide rail 4, and a silicon agent is coated on the upper surface thereof. The support member 14 defines the height positions of the left and right sides of the sunscreen 2.

日除けスクリーン2を引き出す際に、繰り出されたばね部材13の両端が日除けスクリーン2の端縁を挟んで支持部材14に当接するが、支持部材14が軟質材なので、打音を生ぜずに済む。また支持部材14の日除けスクリーン2の摺接面には、シリコン剤がコーティングされているので、滑り摩擦抵抗が少なく、日除けスクリーン2の端縁が擦れて傷むことが防止される。   When the awning screen 2 is pulled out, both ends of the extended spring member 13 come into contact with the support member 14 with the edge of the awning screen 2 interposed therebetween. However, since the support member 14 is a soft material, it is not necessary to generate a hitting sound. Further, since the slidable contact surface of the awning screen 2 of the support member 14 is coated with the silicon agent, the sliding frictional resistance is small, and the edge of the awning screen 2 is prevented from being rubbed and damaged.

本発明にかかる車両用サンシェード装置は、日除けスクリーンの展開・収納動作時の擦過音や打音を低減する効果を有し、車体のガラスサンルーフの下面を覆う車両用サンシェード装置に有用である。   INDUSTRIAL APPLICABILITY The vehicle sunshade device according to the present invention has an effect of reducing scratching sound and hitting sound during the operation and deployment of the sunscreen, and is useful for a vehicle sunshade device that covers the lower surface of the glass sunroof of the vehicle body.
