しかしながら、防具を取り付ける、組立て式の商品は市販されているが、普及していない。当該は、運転者の前面から頭上乃至は背後までを、軟質系の透明素材で覆うだけの方法である。従って、水滴の付着による視界不良や、対象が２輪車が故の横転事故にもつながる。しかも、当該の着脱には、工具と相応の手間や時間を要する。また、そのまま走行すれば、邪魔な存在となる。更には、市販３輪自転車への適用例が見当たらない。 However, although prefabricated products to which armor is attached are commercially available, they are not widely used. The method is simply to cover the driver from the front to the overhead or the back with a soft transparent material. Therefore, it leads to poor visibility due to the adhesion of water droplets and a rollover accident due to the target being a two-wheeled vehicle. Moreover, the attachment / detachment requires a considerable amount of time and effort as a tool. Also, if you drive as it is, it will be an obstacle. Furthermore, there is no example of application to commercially available three-wheeled bicycles.

本発明は、後２輪の３輪自転車である。運転者の前面に風防を、上面には天蓋を付設し、双方に間障を設けている。因って、障壁のない視界と空気の流れを確保し、上記課題を解決する。 The present invention is a three-wheeled bicycle with two rear wheels. A windshield is attached to the front of the driver and a canopy is attached to the upper surface to provide an obstacle on both sides. Therefore, the above-mentioned problems are solved by ensuring a field of view without barriers and an air flow.

本発明は、晴雨両用の３輪自転車である。防雨に加え、遮光と遮熱およびＵＶカットだけでなく、風圧処理にも対応する。即ち、付設する風防と天蓋、双方の間障がもたらす効果により、空気抵抗の低減と、整流の機能を備えている。しかも当該双方とも着脱容易である。加えて、後２輪が故に、安全且つ安心であり、広範な乗用機会を提供できる。 The present invention is a three-wheeled bicycle for both sunny and rainy weather. In addition to rain protection, it supports not only light shielding, heat shielding and UV protection, but also wind pressure treatment. That is, it has a function of reducing air resistance and rectifying by the effect brought about by the obstacle between the windshield and the canopy attached. Moreover, both of them are easy to put on and take off. In addition, because of the rear two wheels, it is safe and secure and can provide a wide range of riding opportunities.

本発明は、図１に示すとおり、前輪１と後輪２の３輪自転車である。ハンドル３の前面に風防４を、運転者の上面には天蓋３を付設し、自転車の速度に見合う装備とするため、当該４と５双方を隔てる間障６を設け、障壁のない視界を確保している。As shown in FIG. 1, the present invention is a three-wheeled bicycle having front wheels 1 and rear wheels 2. A windshield 4 is attached to the front of the handlebar 3 and a canopy 3 is attached to the upper surface of the driver to provide equipment that matches the speed of the bicycle. doing.

一方、図１に示すとおり、風防２を上下２段で構成し、当該２の接合部に狭小空間４を設け、風圧の制御と整流を行なう。図４も参照。On the other hand, as shown in FIG. 1, the windshield 2 is composed of two upper and lower stages, and a narrow space 4 is provided at the joint of the two to control and rectify the wind pressure. See also Figure 4.

図２に示す矢印は、風防２の狭小空間４を経て、天蓋３に至る風の流れである。当該３の後尾に配備する***部７は、間障６からも加わる風圧が誘因となる、当該３の浮揚を抑制するエアスポイラーとしの機能がある。 The arrow shown in FIG. 2 is the flow of wind reaching the canopy 3 through the narrow space 4 of the windshield 2. The raised portion 7 arranged at the tail of the third has a function as an air spoiler that suppresses the levitation of the third, which is triggered by the wind pressure applied from the obstacle 6.

図１と図２に示す、風防２の狭小空間４を構成する仕切５は、整流板であり、中央部のみが当該２上段と、下段の受けとの噛み合わせにより結合し、固定している。 The partition 5 constituting the narrow space 4 of the windshield 2 shown in FIGS. 1 and 2 is a straightening vane, and only the central portion is connected and fixed by meshing with the upper portion of the 2 upper stage and the lower stage receiver. ..

図１と図３で示すのは、風防２と車体との固定方法である。まず、当該２の上段左右内側には、グリップ一体プレート８を接着し、ハンドル１に取付け固定する。当該２の下段左右内側には、プレート９を接着のうえ連結し、Ｔ型具１０を取付ける。 1 and 3 show a method of fixing the windshield 2 to the vehicle body. First, the grip integrated plate 8 is adhered to the left and right inner sides of the upper stage of the second, and is attached and fixed to the handle 1. Plates 9 are bonded and connected to the left and right inside of the lower stage of the second, and the T-shaped tool 10 is attached.

図１と図３では、風防２下段下部の固定の仕掛けも示す。当該２と一体のＴ字型具１０は動かず、当該１０を挟み込む円弧状の接続板１１のスリットが上下に摺動する。図４も参照。また、ハンドル１に直結する当該１１の左右旋回に対応すべく、円形状に面取りを施してある。In FIGS. 1 and 3, a mechanism for fixing the lower part of the lower part of the windshield 2 is also shown. The T-shaped tool 10 integrated with the 2 does not move, and the slit of the arc-shaped connecting plate 11 sandwiching the 10 slides up and down. See also Figure 4. Further, the circular shape is chamfered so as to correspond to the left-right turning of the 11 directly connected to the handle 1.

図１に示す風防２は、上下段とも取り外しできる。まず上段は、ハンドル１からグリップ一体プレート８を外し、仕切５の上下噛み合わせを分離する。次に下段は、接続板１１からＴ字型具１０の固定を解除して引き抜き、上下段ともヒンジ１２を支点に３ッ折りすれば、取り外しできる状態となる。The windshield 2 shown in FIG. 1 can be removed from both the upper and lower stages. First, in the upper stage, the grip integrated plate 8 is removed from the handle 1 to separate the upper and lower meshing of the partition 5. Next, the lower tier can be removed by releasing the fixing of the T-shaped tool 10 from the connection plate 11 and pulling it out, and folding the upper and lower tiers in three with the hinge 12 as a fulcrum.

図５に示すのは、前輪ダブルサスペンションの断面図である。ヘッドチューブ３に内蔵し、フロントフォーク１が路面から受ける衝撃と振動を、上下２段構えで緩和、減衰する。下段は、コイルバネ５と複数の積層弾性素材６を組み合わせており、当該３と内接するインナーチューブ４に組み込み、当該１に直結する。 FIG. 5 is a cross-sectional view of the front wheel double suspension. Built in the head tube 3, the impact and vibration received by the front fork 1 from the road surface are alleviated and damped by the upper and lower two-stage stance. In the lower stage, a coil spring 5 and a plurality of laminated elastic materials 6 are combined, incorporated into an inner tube 4 inscribed with the 3, and directly connected to the 1.

続いて図５に示すのは、上段サスペンションの構造である。まず、ハンドルステム１０のステム昇降ネジ９をネジ受け台座８に差し込み、その下にある固定盤７との空間に、積層弾性素材６を挟み入れる。 Next, FIG. 5 shows the structure of the upper suspension. First, the stem elevating screw 9 of the handle stem 10 is inserted into the screw receiving pedestal 8, and the laminated elastic material 6 is sandwiched in the space with the fixing plate 7 under the screw receiving pedestal 8.

さらに図５で、上段サスペンションの取付け方法を示す。それは、フロントフォーク１からハンドルステム１０に至る連結の仕方である。まず、当該１とフロントフォーク連結板１３および、フロントフォーク連結チューブ１４をフロントフォーク固定ネジ１２により一体化する。次に当該１４の上部から、ハンドルステム連結チューブ１５と一体のハンドルステム連結板１６を挿入し、ハンドルステム固定ネジ１７により、当該１０に固定する。因って、当該１からの振動が当該１０まで伝わり、上段サスペンションが機能する。 Further, FIG. 5 shows a method of mounting the upper suspension. It is a way of connecting from the front fork 1 to the handle stem 10. First, the 1 and the front fork connecting plate 13 and the front fork connecting tube 14 are integrated by the front fork fixing screw 12. Next, the handle stem connecting plate 16 integrated with the handle stem connecting tube 15 is inserted from the upper part of the 14 and fixed to the 10 by the handle stem fixing screw 17. Therefore, the vibration from the 1 is transmitted to the 10 and the upper suspension functions.

図５で加えて示す。分断状態のフロントフォーク回転軸２と、ハンドルステム回転軸１１が連動する仕掛である。それは、フロントフォーク連結チューブ１４と、ハンドルステム連結チューブ１５が、真円以外のチューブであるから。従って、当該１４と当該１５は、上下動しても回転しない。 It is additionally shown in FIG. This is a mechanism in which the front fork rotating shaft 2 in the divided state and the handle stem rotating shaft 11 are interlocked with each other. This is because the front fork connecting tube 14 and the handle stem connecting tube 15 are tubes other than a perfect circle. Therefore, the 14 and the 15 do not rotate even if they move up and down.

図６に示すのは、後２輪の平面図と自在軸４の断面図である。ボトムブラケット１、左右チェーンステー２、チェーンステー連結チューブ３は一体であり、左右Ｌ字型チェーンステー５とハブ８も、フォークエンド６により一体化している。 FIG. 6 shows a plan view of the rear two wheels and a cross-sectional view of the free shaft 4. The bottom bracket 1, the left and right chain stays 2, and the chain stay connecting tube 3 are integrated, and the left and right L-shaped chain stays 5 and the hub 8 are also integrated by the fork end 6.

図６で示す。左右Ｌ字型チェーンステー５は、自在軸４を支点として、前後左右に作動し、ハブ８と左右ホイール７が、当該５の動きに呼応する。 It is shown in FIG. The left and right L-shaped chain stays 5 operate back and forth and left and right with the free shaft 4 as a fulcrum, and the hub 8 and the left and right wheels 7 respond to the movement of the 5.

同じく図６で示す。左右ホイール７は、ハブ８により連結しているが、固定はしていない。然るに、ホイール連結チューブ１０は、当該７とは一体であるが、当該８とは、非接触の回転体である。 It is also shown in FIG. The left and right wheels 7 are connected by a hub 8, but are not fixed. However, the wheel connecting tube 10 is integrated with the 7 but the 8 is a non-contact rotating body.

さらに図６で示す。左右ホイール７は、フリーホイール９により、回転力を得ると共に、ディスクブレーキ１１により同時制動する。 Further shown in FIG. The left and right wheels 7 obtain rotational force by the freewheel 9, and simultaneously brake by the disc brake 11.

図７で示すのは、後２輪のフレーム平面とサスペンション１６の背断面および、側断面である。ボトムブラケット１、シートチューブ１３、枝分かれのシートステー１４は一体であり、当該１４の強度を左右連結チューブ１５が補完している。 FIG. 7 shows the frame planes of the rear two wheels, the back cross section of the suspension 16, and the side cross sections. The bottom bracket 1, the seat tube 13, and the branched seat stay 14 are integrated, and the strength of the 14 is complemented by the left and right connecting tubes 15.

図７で、サスペンション１６の構造と機能を示す。当該１６は、シートステー１４とフォークエンド６との節点に位置し、上下２層に配する較軟２種類の弾性素材から成り、当該６を支点として、上下左右の動きに対応する。 FIG. 7 shows the structure and function of the suspension 16. The 16 is located at a node between the seat stay 14 and the fork end 6, and is composed of two types of elastic materials that are softened and arranged in two upper and lower layers, and corresponds to movements in the vertical and horizontal directions with the 6 as a fulcrum.

図８−１、２、３、４、５は、後輪独立懸架装置の作動説明である。簡略図を用いる。上はチェーンステー連結チューブ１、下はホイール９、それぞれ背面を示す。 8-1, 2, 3, 4, and 5 are explanations of the operation of the rear wheel independent suspension device. Use a simplified diagram. The upper part shows the chain stay connecting tube 1, and the lower part shows the wheel 9, respectively.

図８−１に示す。片側ホイール９が、凸状の障害物を通過する場合である。自在軸２の回転が、Ｌ字型チェーンステー３を押し上げ、連動するサスペンション５を上方圧縮して、衝撃を減衰する。左右ホイール連結チューブ８は、フォークエンド６を支点として、障害物側に上方回転するが、チェーンステー連結チューブ１は、水平を保ち、車体の直立姿勢と安定走行を制御する。 It is shown in FIG. 8-1. This is the case where the one-sided wheel 9 passes through a convex obstacle. The rotation of the free shaft 2 pushes up the L-shaped chain stay 3, compresses the interlocking suspension 5 upward, and damps the impact. The left and right wheel connecting tube 8 rotates upward toward the obstacle side with the fork end 6 as a fulcrum, but the chain stay connecting tube 1 keeps horizontal and controls the upright posture and stable running of the vehicle body.

図８−２で示す。片側ホイール９が、凹状の障害物を通過する場合である。自在軸２の回転が、Ｌ字型チェーンステー３を押し下げ、連動するサスペンション５および、ハブ７と一体のフォークエンド６が下方に伸延し、落差を吸収する。またチェーンステー連結チューブ１は、凸状障害物の場合と同様、水平であり、安定走行を維持する。 It is shown in FIG. 8-2. This is the case where the one-sided wheel 9 passes through a concave obstacle. The rotation of the free shaft 2 pushes down the L-shaped chain stay 3, and the interlocking suspension 5 and the fork end 6 integrated with the hub 7 extend downward to absorb the head. Further, the chain stay connecting tube 1 is horizontal and maintains stable running as in the case of a convex obstacle.

図８−３は、両ホイール９が傾斜面走行する場合を示す。運転者は、斜面の高い方へ体重移動する。従って、自在軸２が、Ｌ字型チェーンステー３を押し上げ、サスペンション５も連動して上方圧縮する。一方、ハブ７と一体の当該９、フォークエンド６は斜面との平行を保つ。しかも、サスペンション５に対する加圧により、当該９の回転数は、斜面の高い方が低い方に比べて減少するので、直進走行の保持が可能となる。 FIG. 8-3 shows a case where both wheels 9 run on an inclined surface. The driver shifts his weight to the higher slope. Therefore, the free shaft 2 pushes up the L-shaped chain stay 3, and the suspension 5 is also interlocked to compress upward. On the other hand, the 9 and the fork end 6 integrated with the hub 7 are kept parallel to the slope. Moreover, due to the pressurization of the suspension 5, the rotation speed of the 9 is reduced on the higher slope than on the lower slope, so that the straight running can be maintained.

さらに図８−３で示す。斜面走行において、傾斜角度がより大きい場合である。運転者の体重移動が大きくなるため、低い側のハブ５と、一体のホイール９は荷重ゼロとなる。そこで低い側の当該９の接地を維するため、フォークエンド６が左右の傾斜に加え、下方伸延し、直進性と安定走行をサポートする。 Further shown in FIG. 8-3. This is the case when the inclination angle is larger in the slope running. Since the weight shift of the driver becomes large, the load of the hub 5 on the lower side and the wheel 9 integrated with the hub 5 becomes zero. Therefore, in order to maintain the ground contact of the 9 on the lower side, the fork end 6 extends downward in addition to the left and right inclination to support straightness and stable running.

図８−４で示す。両ホイール９が、凸状または、凹状の障害を同時に通過する場合である。両サスペンション５には、車体と運転者の荷重が付加される。即ち、当該５は、凸状の障害に対して上方圧縮を、凹状の障害には下方圧縮して衝撃を吸収し、安定走行を保持する。 It is shown in FIG. 8-4. This is a case where both wheels 9 pass through a convex or concave obstacle at the same time. The load of the vehicle body and the driver is applied to both suspensions 5. That is, the fifth item compresses upward for convex obstacles and downwards for concave obstacles to absorb impact and maintain stable running.

図８−５で示すのは、平坦な路面走行での方向転換である。運転者の体重移動が関係する。つまり、左右ホイール９に与える付加の強弱が、当該９の回転数の差となり、進む方向を決める。 FIG. 8-5 shows a change of direction on a flat road surface. The driver's weight shift is involved. That is, the strength of the addition given to the left and right wheels 9 is the difference in the number of rotations of the 9 and determines the direction of travel.

図９、図１０に示すのは、天蓋を支える天蓋主軸の延伸、短縮背断面である。当該は天蓋の左右伸縮を行なう。操作は、両端にあるメインパイプ固定軸２のプッシュ・プルによる。図９は走行モードの延伸、図１０は駐輪モードの短縮である。 9 and 10 show a stretched and shortened dorsal cross section of the canopy spindle that supports the canopy. The canopy expands and contracts left and right. The operation is by push-pull of the main pipe fixing shaft 2 at both ends. FIG. 9 shows the extension of the traveling mode, and FIG. 10 shows the shortening of the bicycle parking mode.

図９では構造を示す。メインパイプ１、メインパイプ固定軸２、主軸パイプ３、ラック５は一体化している。収納パイプ７は、主軸支持アーム９に固定し、当該１、２、３、５を被覆収納する。また、当該７には、延伸保持のため、延伸ストッパー１０を両端の上下対角に設けてある。なお、歯車軸６の両端は、当該７に固定している。 FIG. 9 shows the structure. The main pipe 1, the main pipe fixing shaft 2, the spindle pipe 3, and the rack 5 are integrated. The storage pipe 7 is fixed to the spindle support arm 9, and the 1, 2, 3, and 5 are covered and stored. Further, the 7 is provided with stretching stoppers 10 diagonally at both ends in order to hold the stretching. Both ends of the gear shaft 6 are fixed to the 7.

図１０では、主軸パイプ３、左右短縮時における構造を示す。歯車４の回転により、ラック６の位置関係が逆転すると共に、短縮保持のため、収納ストッパー１１が作動する。また、収納パイプ７には、グリップ８を付設してあり、ヒンジ１２を支点として、後方に開閉する。従って、天蓋主軸全体を、主軸支持アーム９から取外しできる。 FIG. 10 shows the structure of the spindle pipe 3 when the left and right sides are shortened. The rotation of the gear 4 reverses the positional relationship of the rack 6, and the storage stopper 11 operates for shortening and holding. A grip 8 is attached to the storage pipe 7, and the storage pipe 7 is opened and closed rearward with the hinge 12 as a fulcrum. Therefore, the entire canopy spindle can be removed from the spindle support arm 9.
