Special table 2004-523405

しかし、上記従来の格納式ルーフでは、図６に示すように、蓋８１を開けた車両後部の格納室８内への、前側ルーフ部１と後側ルーフ部２の格納を開始する際に、前側ルーフ部１が使用状態の略水平姿勢のままで後方へ移動してフロントウインドウ部３から離れるため、ここに生じた隙間から、前側ルーフ部１上面に残った雨水や洗浄水の水滴がインストルメントパネル上や前席シート上等に落下するという問題があった。 However, in the conventional retractable roof, as shown in FIG. 6, when starting to store the front roof portion 1 and the rear roof portion 2 in the storage chamber 8 in the rear portion of the vehicle with the lid 81 opened, Since the front roof portion 1 remains rearward from the front window portion 3 while remaining in a substantially horizontal posture in use, water droplets of rain water and washing water remaining on the upper surface of the front roof portion 1 are installed in the instrument through the gap generated here. There was a problem of falling on the ment panel or the front seat.

そこで、本発明はこのような課題を解決するもので、ルーフ格納時の車内への水滴落下を効果的に防止できる車両の格納式ルーフを提供することを目的とする。 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a retractable roof for a vehicle that can effectively prevent water droplets from falling into the vehicle when the roof is stored.

上記課題を解決するために、本第１発明では、ルーフ（Ｒ）を前側ルーフ部（１）と後側ルーフ部（２）に分割し、分割された前後のルーフ部（１，２）を格納機構（６，７）によって車両後方へ移動させて車両後部（８）へ格納するようにした車両の格納式ルーフにおいて、格納機構（６，７）を、その格納動作開始時に前側ルーフ部（１）を車両後方へ移動させるのに先立って前方へ下り傾斜させて当該前側ルーフ部（１）の上面に付着した水滴をフロントウインドウ（３）部の車両外表面へ流出させるように設定する。この場合、上記格納機構は車両後方から延びる旋回アーム（６）を備えており、当該旋回アーム（６）の先端（６１）に長穴（６２）を設けて、当該長穴（６２）内に前側ルーフ部（１）の後端部に設けたピン（５１）を移動可能に挿入して、格納動作開始時の旋回アーム先端（６１）の上後方移動に伴いピン（５１）が長穴（６２）内を相対移動して、この相対移動の間、前側ルーフ部（１）が後方移動することなくその後端部（１２）が持ち上げられて前方へ下り傾斜させられるようにすることができる。 In order to solve the above problems, in the first invention, the roof (R) is divided into a front roof portion (1) and a rear roof portion (2), and the divided front and rear roof portions (1, 2) are divided. In a retractable roof of a vehicle that is moved rearward of the vehicle by the storage mechanism (6, 7) and stored in the rear part (8) of the vehicle, the storage mechanism (6, 7) is moved to the front roof portion ( Prior to moving the vehicle 1) to the rear of the vehicle, the vehicle is set so that water drops adhering to the upper surface of the front roof portion (1) are allowed to flow down to the vehicle outer surface of the front window (3) portion. In this case, the storage mechanism includes a turning arm (6) extending from the rear of the vehicle, and a long hole (62) is provided at the tip (61) of the turning arm (6). A pin (51) provided at the rear end of the front roof portion (1) is movably inserted, and the pin (51) is moved into a long hole ( 62) It is possible to make a relative movement in the interior, and during this relative movement, the rear end portion (12) is lifted and tilted downward without the front roof portion (1) moving backward.

本第１発明においては、格納動作開始時に前側ルーフ部を車両後方へ移動させるのに先立って前方へ下り傾斜させて当該前側ルーフ部の上面に付着した水滴をフロントウインドウ部側の車両外表面へ流出させているから、続く車両後方への移動時のインストルメントパネル等への水滴落下が効果的に防止される。 In the first aspect of the invention, when the front roof portion is moved to the rear of the vehicle at the start of the storing operation, the water droplets that are inclined downward and attached to the upper surface of the front roof portion are applied to the outer surface of the vehicle on the front window portion side. Since it is made to flow out, the water droplet fall to the instrument panel etc. at the time of the subsequent movement to the back of a vehicle is prevented effectively.

また、本第２発明では、ルーフを、互いの端縁を対向させて接続された一対のルーフ部で構成し、これらルーフ部を格納機構によって車両内へ格納するようにした車両の格納式ルーフにおいて、上記格納機構を、その格納動作開始時に両ルーフ部を格納方向へ移動させるのに先立って、互いに対向する上記ルーフ部の端縁のうち少なくとも一方のルーフ部の端縁を上方へ移動させて上記少なくとも一方のルーフ部を傾斜させるように設定する。 According to the second aspect of the invention, the roof is constituted by a pair of roof portions connected with their edges facing each other, and the roof portion is stored in the vehicle by a storage mechanism. In the storage mechanism, at the start of the storage operation, before moving both the roof parts in the storage direction, the edge of at least one of the roof parts facing each other is moved upward. The at least one roof portion is set to be inclined.

本第２発明においては、格納動作開始時に両ルーフ部を格納方向へ移動させるのに先立って、互いに対向する上記ルーフ部の端縁のうち少なくとも一方のルーフ部の端縁を上方へ移動させて上記少なくとも一方のルーフ部を傾斜させるようにして、当該少なくとも一方のルーフ部の上面に付着した水滴を車両外表面へ流出させているから、続く格納方向への移動時における車内への水滴落下が未然に防止される。 In the second aspect of the invention, prior to moving both roof parts in the retracting direction at the start of the storing operation, the edge of at least one of the roof parts facing each other is moved upward. The at least one roof portion is inclined so that the water droplets adhering to the upper surface of the at least one roof portion flow out to the outer surface of the vehicle. Prevented in advance.

なお、上記カッコ内の符号は、後述する実施形態に記載の具体的手段との対応関係を示すものである。 In addition, the code | symbol in the said parenthesis shows the correspondence with the specific means as described in embodiment mentioned later.

以上のように、本発明の車両の格納式ルーフによれば、ルーフ格納時の車内への水滴落下を効果的に防止することができる。 As described above, according to the retractable roof of the vehicle of the present invention, it is possible to effectively prevent water droplets from dropping into the vehicle when the roof is stored.

（第１実施形態）
図１にはルーフを使用している状態での格納式ルーフの格納機構の側面図を示す。図１において、ルーフＲは前側ルーフ部１と後側ルーフ部２に分割されており、使用状態では、前側ルーフ部１の前端がフロントウインドウ部３の上端（後端）に接して位置するとともに、後側ルーフ部２の前端が前側ルーフ部１の後端に、後側ルーフ部２の後端がリアウインドウ部４の上端（前端）に接して位置して、上方へやや膨出湾曲しつつフロントウインドウ部３からリアウインドウ部４へ至り乗員Ｍの上方を覆うルーフ面が形成されている。なお、前側ルーフ部１および後側ルーフ部２は両側縁１１，２１（図３参照）が上方へ突出して、側方への水滴の流出が阻止されている。 (First embodiment)
FIG. 1 shows a side view of a retractable roof retracting mechanism in a state where the roof is used. In FIG. 1, the roof R is divided into a front roof portion 1 and a rear roof portion 2, and in use, the front end of the front roof portion 1 is positioned in contact with the upper end (rear end) of the front window portion 3. The front end of the rear roof portion 2 is located at the rear end of the front roof portion 1 and the rear end of the rear roof portion 2 is in contact with the upper end (front end) of the rear window portion 4 and is slightly bulging upward. On the other hand, a roof surface that extends from the front window portion 3 to the rear window portion 4 and covers the occupant M is formed. The front roof portion 1 and the rear roof portion 2 have both side edges 11 and 21 (see FIG. 3) protruding upward to prevent water droplets from flowing out to the side.

図１において、前側ルーフ部１の後端部１２下面両側（一方のみ図示）にはリンクアーム５が埋設されており、これらリンクアーム５の前端には車両後方から延びる旋回アーム６の先端６１が回動可能に連結されている。この連結部の詳細を図２に示す。旋回アーム６の先端にはアーム長手方向へ延びる長穴６２が形成されており、当該長穴６２内にリンクアーム５の前端に立設されたピン５１が位置している。旋回アーム６は基端部６３が下方へ湾曲して車両のサイドボデー内に位置する回転軸６４に固定されており、当該回転軸６４は減速機構６５を介してモータ６６によって正逆回転駆動される。 In FIG. 1, link arms 5 are embedded on both sides (only one is shown) of a rear end portion 12 of a front roof portion 1, and a front end 61 of a swivel arm 6 extending from the rear of the vehicle is provided at the front ends of these link arms 5. It is connected so that it can rotate. Details of this connecting portion are shown in FIG. A long hole 62 extending in the longitudinal direction of the arm is formed at the tip of the swivel arm 6, and a pin 51 erected at the front end of the link arm 5 is located in the long hole 62. The swivel arm 6 is fixed to a rotating shaft 64 whose base end portion 63 is curved downward and is positioned in the side body of the vehicle. The rotating shaft 64 is driven to rotate forward and backward by a motor 66 via a speed reduction mechanism 65. The

上記リンクアーム５の後端には車両後方から延びる旋回アーム７の先端７１が回動可能に連結されている。旋回アーム７は中間部が後側ルーフ部２の下面内に埋設されてこれと一体になっている。旋回アーム７の基端部７２は下方へ湾曲して、上記回転軸６４の後方に設けた従動軸７３に固定されている。また、リアウインドウ部４は図略の支持部材によって車両のサイドボデー内に位置する回転軸４１に固定されており、当該回転軸４１は減速機構４２を介してモータ４３によって正逆回転駆動される。なお、車両の後部には蓋体８１（図３参照）によって開閉される格納室８が設けられている。 A distal end 71 of a turning arm 7 extending from the rear of the vehicle is rotatably connected to the rear end of the link arm 5. The revolving arm 7 has an intermediate portion embedded in the lower surface of the rear roof portion 2 and integrated therewith. A base end portion 72 of the swivel arm 7 is curved downward and is fixed to a driven shaft 73 provided behind the rotation shaft 64. Further, the rear window portion 4 is fixed to a rotating shaft 41 located in the side body of the vehicle by a support member (not shown), and the rotating shaft 41 is driven to rotate forward and backward by a motor 43 via a speed reduction mechanism 42. . A storage chamber 8 that is opened and closed by a lid 81 (see FIG. 3) is provided at the rear of the vehicle.

このような構造の格納式ルーフにおいて、ルーフＲを格納する場合には、モータ６６によって旋回アーム６を回転軸６４を中心に図１の時計方向へ回動させる。この回動によって旋回アーム６の先端６１は上後方へ移動するが、前側ルーフ部１と一体のリンクアーム５のピン５１が旋回アーム先端６１の長穴６２内を相対移動する（図２の矢印）ため、この間は前側ルーフ部１は後方へ移動せず、その後端部１２のみが持ち上げられる（図１の鎖線）。これにより、前側ルーフ部１は前端がフロントウインドウ部３に接した状態で前方へ下り傾斜させられ、当該前側ルーフ部１の上面に付着した雨水や洗浄水の水滴が図３に示すようにフロントウインドウ部３のガラス外表面上へ流出させられる。なお、後側ルーフ部２は使用状態でも比較的大きく後方へ下り傾斜しているから上面への水滴の付着は少ない。 In the retractable roof having such a structure, when the roof R is stored, the revolving arm 6 is rotated about the rotation shaft 64 in the clockwise direction in FIG. By this rotation, the tip 61 of the swivel arm 6 moves upward and rearward, but the pin 51 of the link arm 5 integral with the front roof portion 1 relatively moves within the elongated hole 62 of the swivel arm tip 61 (arrow in FIG. 2). Therefore, during this time, the front roof portion 1 does not move rearward, and only the rear end portion 12 is lifted (dashed line in FIG. 1). As a result, the front roof portion 1 is tilted downward with the front end in contact with the front window portion 3, and rainwater and washing water droplets adhering to the upper surface of the front roof portion 1 are moved to the front as shown in FIG. It flows out on the glass outer surface of the window part 3. It should be noted that the rear roof portion 2 is relatively large and tilts downward in the use state, so that water droplets do not adhere to the upper surface.

旋回アーム６の回動に伴って旋回アーム７およびこれと一体の後側ルーフ部２も従動軸７３を中心に同方向へ回動を開始し、同時にリアウインドウ部４がモータ４３により駆動されて回転軸４１を中心に図１の時計方向へ回動を開始する。そして、リアウインドウ部４が反転状態で格納室８の最下位置へ旋回収納されるとともに（図１の鎖線）、その上方に後側ルーフ部２が反転状態で旋回収納され、さらにその上方に前側ルーフ部１が非反転状態で旋回収納される（図１の鎖線）。 As the turning arm 6 turns, the turning arm 7 and the rear roof portion 2 integrated therewith also start turning in the same direction around the driven shaft 73, and at the same time, the rear window portion 4 is driven by the motor 43. The rotation is started in the clockwise direction in FIG. Then, the rear window portion 4 is turned and stored to the lowest position of the storage chamber 8 in the inverted state (the chain line in FIG. 1), and the rear roof portion 2 is turned and stored in the inverted state above it. The front roof portion 1 is turned and stored in a non-inverted state (a chain line in FIG. 1).

（第２実施形態）
旋回アーム６の先端６１に形成される長穴６２を図４に示すように、アーム先端６１の旋回軌跡と一致しない限りでリンクアーム５のピン５１の移動方向へ傾斜させて形成しても良く、このようにするとピン５１の長穴６２内での相対移動がよりスムーズになされる。 (Second Embodiment)
As shown in FIG. 4, the long hole 62 formed in the tip 61 of the swivel arm 6 may be formed to be inclined in the moving direction of the pin 51 of the link arm 5 as long as it does not coincide with the swivel trajectory of the arm tip 61. In this way, the relative movement of the pin 51 within the elongated hole 62 is made smoother.

（第３実施形態）
図５に示すように、前側ルーフ部１の下面にバイブレータ１０を設置し、前側ルーフ部を傾斜させたときにバイブレータ１０を振動させるようにすれば、ルーフ上面に付着した水滴をさらに効率的にフロントウインドウ部３へ流下させることができる。
（その他の実施形態） (Third embodiment)
As shown in FIG. 5, if the vibrator 10 is installed on the lower surface of the front roof portion 1 and the vibrator 10 is vibrated when the front roof portion is tilted, water droplets attached to the upper surface of the roof can be more efficiently removed. It can flow down to the front window part 3.
(Other embodiments)

上記各実施形態では、収納に先立って前側ルーフ部のみを傾斜させる場合について説明したが、後側ルーフ部のみを傾斜させ、あるいは前側および後側の両ルーフ部をいずれも傾斜させるようにしても良い。この場合には、バイブレータを後側ルーフ部にも設置するとより効果がある。 In each of the above embodiments, the case where only the front roof portion is inclined prior to storage has been described. However, only the rear roof portion is inclined, or both the front and rear roof portions are inclined. good. In this case, it is more effective to install the vibrator also on the rear roof portion.
