Description
【０００１】[0001]
本考案は、後輪を一輪車構造とした自転車に関する。 The present invention relates to a bicycle whose rear wheel has a unicycle structure.
【０００２】[0002]
現在主として利用されている自転車は、周知の如く前輪と後輪との間にペダル が設けられており、チエンで後輪に動力を伝達する型のものが最も多く、また、 近来は、サドルの真下に一輪のみを取付けた一輪車の普及もめざましいものがあ る。 As is well known, most bicycles currently used have pedals between the front and rear wheels, and most of them are of the type that transmits power to the rear wheels with a chain. There is also a remarkable spread of unicycles that have only one wheel installed directly underneath.
【０００３】[0003]
従来の前輪と後輪の間にペダルを設けた形式のものは、ペダル部分が前後輪間 に設けられており、しかも前かがみの姿勢で乘る関係で、前後輪間の全長は通常 約１，７００mm位を必要とし、普通乗用車のトランク内には収納ができない問題 点を有し、また、一輪車は、近来、子供達に必要とするバランス感覚、敏しょう 性、背筋力の強化等の目的で小学校の体育指導にも正式に取り入れられてきてい るが、反面、高度のバランス感覚、敏しょう性を必要とするために、通常の二輪 の自転車には乗れても、一輪車を乗りこなすことは困難であった。 In the conventional type in which a pedal is provided between the front wheel and the rear wheel, the pedal portion is provided between the front and rear wheels, and the total length between the front and rear wheels is usually about 1, because the pedal is leaned forward. It requires about 700 mm and cannot be stored in the trunk of an ordinary passenger car. In addition, unicycles are used for the purpose of strengthening the sense of balance, agility, and back strength that children need in the near future. Although it has been officially incorporated into physical education at elementary schools, it requires a high sense of balance and agility, so even if you can ride a normal two-wheeled bicycle, it is difficult to ride a unicycle. there were.
【０００４】 本考案は、従来の技術の有するこのような問題点に鑑みてなされたものであり 、その目的とするところは、前後輪の間隔を著しく狭くすることができ、折畳み 作業等を一切必要とせず、そのまゝ軽四輪乗用車のトランク内に収納して、レジ ャー地等にも自由に持ち運びのできる全長１，１５０mm以下に製作することが可 能であり、また、後輪側が一輪車構造であるため全体構造としては二輪車を構成 しているが、身体の重心を後に移すと一輪車の乗車姿勢に近づき、自然に一輪車 のバランス感覚、敏しょう性等も身につき、背筋力の強化にもつながり、さらに 乗り慣れてくると前輪側を切離して一輪車としても楽しむことのできる自転車を 提供することを目的としている。The present invention has been made in view of the above problems of the prior art. The object of the present invention is to significantly reduce the distance between the front and rear wheels, and to perform folding work at all. It is possible to store it in the trunk of a light-duty four-wheeled passenger car without needing it, and to make it with a total length of 1,150 mm or less that can be freely carried to the cashier area. Since it is a unicycle structure, it constitutes a two-wheeled vehicle as a whole, but if the center of gravity of the body is moved to the rear, it will approach the unicycle's riding posture and naturally acquire the sense of balance and agility of the unicycle, and strengthen the back muscle strength. The aim is to provide a bicycle that can be enjoyed as a unicycle by disconnecting the front wheels when the driver gets used to it.
【０００５】[0005]
上記目的を達成するために、本考案の後輪を一輪車構造とした自転車は、一輪 車の構造の後輪のフレームに、一端側には前輪及びハンドルを取付けたフレーム の他の一端側を取付けしてなるものである。 In order to achieve the above object, a bicycle having a unicycle structure as a rear wheel of the present invention has a rear wheel frame of a unicycle structure, one end side of which is attached to the other end side of a frame to which a front wheel and a handle are attached. It will be done.
【０００６】[0006]
上記のように構成された後輪を一輪車構造とした自転車は前後輪の距離が狭く できるので、軽四輪自動車のトランクにも収容ができ、また、ペダルがサドルの 真下で回転して一輪車と同じ構造であるが故に身体を後方に起こしていくと、後 輪側に身体の重心が移り、一輪車のバランス感覚を除々に体感することができ、 また、前輪を取付けたフレームを一時取外すと簡単に一輪車として独立して使用 することもできる。 A bicycle with a unicycle structure with rear wheels configured as described above can be stored in the trunk of a light four-wheeled vehicle because the distance between the front and rear wheels can be narrowed, and the pedals can rotate underneath the saddle to make it a unicycle. Because of the same structure, when the body is raised backward, the center of gravity of the body shifts to the rear wheel side, allowing you to gradually feel the balance feeling of the unicycle, and it is easy to temporarily remove the frame with the front wheel attached. It can also be used independently as a unicycle.
【０００７】[0007]
実施例について図面を参照して説明すると、図１において、ペダル１、１の回 転中心軸２は、サドル３と後輪４を一直線状に結ぶ後輪フレーム５の下端部に設 けられて後輪４を直接回転させる構造に形成されており、一輪車と略同一の構造 に形成されている。 An embodiment will be described with reference to the drawings. In FIG. 1, a rotation center shaft 2 of pedals 1 and 1 is provided at a lower end portion of a rear wheel frame 5 that connects a saddle 3 and a rear wheel 4 in a straight line. The rear wheel 4 is directly rotated, and has substantially the same structure as a unicycle.
【０００８】 中間フレーム６の一端側は、前記後輪フレーム５に固着されており、他の一端 側には、前輪７を取付けた前ホーク８及びハンドル９を挿嵌した前パイプ１０を 固着する。One end of the intermediate frame 6 is fixed to the rear wheel frame 5, and the other end of the intermediate frame 6 is fixed with a front fork 8 having a front wheel 7 attached thereto and a front pipe 10 having a handle 9 inserted therein. .
【０００９】 また、図２及び図３において中間フレーム６の後輪フレーム５への固着側の一 端に、例えば後輪フレーム５に挿嵌できる太さのパイプで形成した取付具１１を 固着し、締め付け螺子１２、１２を横方向に挿通して、該締め付け螺子１２、１ ２を後輪フレーム５に穿設した螺子挿通孔１３、１３に挿通して締め付けできる ように形成してもよい。また、取付具１１はパイプ状に限定されるものではなく 、パイプを長手方向に一部分を切り裂いて、切り裂き部分の開口巾を螺子で締め 付け狭くして後輪フレーム５に左右から抱持する形で取付ける構成等、パイプ部 分へ更に略パイプ状のものを挿嵌止持する場合の公知の簡易な脱着方法は全て採 用が可能である。 また、図４に示す如く、中間フレーム６の一端側に取付ける前輪７は径小にす ることもでき、更に前ホーク８及びハンドル９の形状、構造は簡単なものを選択 することができる。In addition, in FIGS. 2 and 3, at one end on the side where the intermediate frame 6 is fixed to the rear wheel frame 5, a fixture 11 formed of, for example, a pipe having a thickness that can be inserted into the rear wheel frame 5 is fixed. Alternatively, the tightening screws 12 and 12 may be laterally inserted, and the tightening screws 12 and 12 may be formed so that they can be tightened by being inserted into the screw insertion holes 13 and 13 formed in the rear wheel frame 5. The mounting tool 11 is not limited to the pipe shape, and a part of the pipe is cut in the longitudinal direction, and the opening width of the cut portion is tightened with a screw to narrow it and hold it from the left and right sides of the rear wheel frame 5. Any known simple attachment / detachment method can be applied when inserting and fixing a substantially pipe-shaped object into the pipe portion, such as a configuration of attaching by. Further, as shown in FIG. 4, the front wheel 7 attached to one end side of the intermediate frame 6 can have a small diameter, and the front fork 8 and the handle 9 can have a simple shape and structure.

以上説明したように、本考案の後輪を一輪車構造とした自転車は、軽四輪自動 車のトランク内にもそのまゝの状態で即収容ができ、レジャー地までも自由に持 ち運びが可能な簡単な構造の自転車となり、通常の一輪車と異なり長時間の長距 離走行も可能で、バードウォッチング、偵察行動等にも適し、また二輪車構造で ありながら一輪車の乗車感覚も体感することができ、前輪側が瞬間的に下部のバ ランスを助ける利用方法もできるので一輪車の苦手な子供達でも除々に一輪車に 乗れるように練習ができ、また、しかも螺子を緩めて取付具を後輪フレームから 切り離す簡単な作業で、一輪車となり、レジャー地等で一輪車、二輪車、双方を 使い分けて楽しむこともできる。 As explained above, the bicycle with the rear wheel of the present invention, which has a unicycle structure, can be immediately stored in the trunk of a mini four-wheeled motor vehicle as it is, and can be freely carried to leisure areas. It becomes a bicycle with a simple structure that allows for long-distance running unlike ordinary unicycles, is suitable for bird watching, reconnaissance, etc.Also, although it is a two-wheeled structure, you can experience the feeling of riding a unicycle. You can also use it to help the front wheel momentarily support the lower balance, so even children who are not good at unicycles can practice so that they can gradually ride on unicycles, and loosen the screws and remove the attachment from the rear frame. With the simple work of disconnecting, it becomes a unicycle, and you can enjoy using both unicycles and motorcycles in leisure areas.
