ところで、従来の三輪車は、特定の年齢の幼児の平均的な体格を想定して、全体の大きさや、サドルの大きさ等が設定されている。
このため、前記想定よりも小さな体格の幼児の場合、三輪車をこぐ体力や運動能力が備わっていたとしても、ペダルに足が届かずにこぐことができないという問題が生じる場合がある。
また、幼児が成長して前記想定よりも大きくなると、臀部（尻）がサドルからはみ出し、三輪車全体の加重バランスが崩れ、走行し難くなったり、相対的に長くなった脚部のためにペダルを踏む操作や地面を蹴る操作がし難くなったりするおそれがある。
そして、前者の場合、三輪車自体を小型のものに変更する必要が生じ、後者の場合には、三輪車自体を大型のものに変更する必要が生じる。 By the way, in the conventional tricycle, the overall size, the size of the saddle, and the like are set assuming the average physique of an infant of a specific age.
For this reason, in the case of an infant having a physique smaller than the above-mentioned assumption, there may be a problem that even if the infant has physical strength and athletic ability to ride a tricycle, it cannot reach the pedal and cannot pedal.
Also, when the infant grows and becomes larger than expected, the buttocks (buttocks) protrude from the saddle, and the weight balance of the entire tricycle is lost, making it difficult to run or pedaling due to the relatively long legs. It may be difficult to perform a stepping operation or a kicking operation on the ground.
In the former case, it is necessary to change the tricycle itself to a small one, and in the latter case, it is necessary to change the tricycle itself to a large one.

A rear wheel 70 is rotatably supported at each end in the extending direction. An uneven anti-slip portion is provided on the upper half side of the rear wheel axle 60 as necessary to make it easier for a child or the like to put a foot.
The rear wheels 70, 70 on both sides in the vehicle width direction are formed to have a smaller diameter than the front wheel 30 according to the illustrated example.

サドル８０は、その下面側が、車体フレーム部１０の水平状フレーム部１１を車幅方向へ跨る凹溝状に形成され、この凹溝状部分を水平状フレーム部１１に嵌め合わせて、ブラケット及びネジ等により止着固定される。
なお、このサドル８０は、単一の一体の部材から構成してもよいし、硬質部材と、該硬質部材を覆う軟質のクッション部材等の複数の部材から構成してもよい。 The lower surface side of the saddle 80 is formed in a groove shape that straddles the horizontal frame portion 11 of the vehicle body frame portion 10 in the vehicle width direction, and the groove portion is fitted to the horizontal frame portion 11, and a bracket and a screw are formed. It is fixed and fixed by the like.
The saddle 80 may be formed of a single integral member, or may be formed of a hard member and a plurality of members such as a soft cushion member that covers the hard member.

このサドル８０の上面側には、後輪軸部６０の中心よりも前側に、前後方向へ連続する長尺状の着座部８１が設けられ、着座部８１よりも後側に、後輪軸部６０を前後に跨る長さの非着座部８２が設けられる。   On the upper surface side of the saddle 80, a long seat portion 81 continuous in the front-rear direction is provided on the front side of the center of the rear wheel shaft portion 60, and the rear wheel shaft portion 60 is provided on the rear side of the seat portion 81. A non-seat portion 82 having a length extending in the front-rear direction is provided.

着座部８１は、前部寄りに幼児を跨らせて着座させる前側着座領域８１ａと、後部寄りに幼児を跨らせて着座させる着座領域であって前側着座領域８１ａよりも前後に長い後側着座領域８１ｂとを確保してその全長が設定される。
具体的に説明すれば、着座部８１は、例えば、以下の二つの方法（図３及び図４参照）により設計することが可能である。 The seating portion 81 is a front seating region 81a in which the infant is straddled toward the front and seated, and a seating region in which the infant is straddled near the rear and is longer in the front and rear than the front seating region 81a. The entire length is set while securing the seating area 81b.
More specifically, the seating portion 81 can be designed by, for example, the following two methods (see FIGS. 3 and 4).

図３に例示する設計方法では、着座部８１の前部側に、比較的小柄な幼児を跨らせて着座させる前側着座領域８１ａを想定し、この前側着座領域８１ａよりも後側に、前側着座領域８１ａよりも前後方向に長い後側着座領域８１ｂを想定し、これら前側着座領域８１ａの長さａと後側着座領域８１ｂの長さｂを合計して、着座部８１全体の長さＬ１を求める。
なお、図示例によれば、前側着座領域８１ａは、着座部８１全体の長さＬ１の中心よりも前側に位置する。 In the design method illustrated in FIG. 3, a front seating area 81 a in which a relatively small infant is straddled and seated is assumed on the front side of the seating section 81, and the front side is located behind the front seating area 81 a. Assuming a rear seating area 81b that is longer in the front-rear direction than the seating area 81a, the length a of the front seating area 81a and the length b of the rear seating area 81b are summed, and the total length L1 of the seating portion 81 is calculated. Ask for.
According to the illustrated example, the front seating area 81a is located on the front side of the center of the entire length L1 of the seating portion 81.

また、図４に例示する他の設計方法では、着座部８１の前部寄りに、比較的小柄な幼児を跨らせて着座させる前側着座領域８１ａを想定し、前側着座領域８１ａの後端側に前端側の重なり代ｃを重ね合わせるように後側着座領域８１ｂを想定し、前側着座領域８１ａの長さと後側着座領域８１ｂの長さの合計から重なり代８１ｃを減じて、着座部８１全体の長さＬ１を求める。
なお、図示例によれば、重なり代ｃは、着座部８１全体の長さＬ１の中心を含むように位置する。 Further, in another design method illustrated in FIG. 4, a front seating area 81a where a relatively small infant is straddled and seated is positioned near the front of the seating section 81, and the rear end side of the front seating area 81a is assumed. The rear seating area 81b is assumed so that the overlapping margin c on the front end side is overlapped with the front end side, and the overlapping margin 81c is subtracted from the sum of the length of the front seating area 81a and the length of the rear seating area 81b, and Is determined.
According to the illustrated example, the overlap margin c is located so as to include the center of the length L1 of the entire seating portion 81.

前側着座領域８１ａは、比較的低い所定の年齢（例えば、１．５歳）の平均的な体格の幼児が着座部８１に跨って着座した際に前後方向にわたって占領される領域であり、その前後方向の長さａは実験的に求めることが可能である。
後側着座領域８１ｂは、前記年齢よりも高い所定の年齢（例えば、４．５歳）の平均的な体格の幼児が着座部８１に跨って着座した際に前後方向にわたって占領される領域であり、その前後方向の長さｂは実験的に求めることが可能である。 The front seating area 81a is an area that is occupied in the front-rear direction when an infant of a relatively low predetermined age (for example, 1.5 years) of average physique sits across the seating portion 81, and is occupied in the front-rear direction. The length a in the direction can be determined experimentally.
The rear seating area 81b is an area that is occupied in the front-rear direction when an infant of an average physique of a predetermined age (for example, 4.5 years) higher than the above age sits across the seating portion 81. , The length b in the front-rear direction can be determined experimentally.

特に、後者（図４参照）は、安全上等の観点から、二人の幼児が同時に前後に跨って座ることを避けるようにした態様である。   In particular, the latter (refer to FIG. 4) is an aspect in which two infants are prevented from sitting on the front and back simultaneously from the viewpoint of safety and the like.

本願発明者は、試行錯誤の実験の末、着座部８１の前後方向の全体の長さＬ１を、サドル８０の全長Ｌ０の７０〜８５％の範囲内であって、且つ２８５〜３５０ｍｍの範囲内とした。
着座部８１全体の長さＬ１を前記範囲の下限よりも小さくした場合は、１．５歳の幼児が成長して平均的な体格の５歳の幼児になった場合に、この幼児の臀部が着座部８１からはみ出たり、脚部がペダルまでの距離に相対し長すぎたりして、バランスの良い着座が困難になるおそれがある。
着座部８１の全体の長さＬ１を前記範囲の上限よりも大きくした場合には、二人の幼児が同時に前後に跨って座ってしまう可能性が著しく高くなる。
なお、着座部８１全体の長さＬ１は、より好ましくは２８６〜３４８ｍｍの範囲内とされ、本実施の形態の一例では、着座部８１全体の長さＬ１を３１７ｍｍ、サドル８０の全長Ｌ０を４０９ｍｍに設定している。 The inventor of the present application has set the overall length L1 of the seating portion 81 in the front-rear direction within a range of 70 to 85% of the total length L0 of the saddle 80 and a range of 285 to 350 mm after trial and error experiments. And
If the overall length L1 of the seating portion 81 is smaller than the lower limit of the range, when the 1.5-year-old infant grows and becomes a 5-year-old infant with an average physique, the buttocks of this infant are There is a possibility that well-balanced seating may be difficult due to the protrusion from the seating portion 81 or the leg portion being too long relative to the distance to the pedal.
If the overall length L1 of the seating portion 81 is larger than the upper limit of the above range, the possibility that two infants will sit on the front and back at the same time significantly increases.
Note that the entire length L1 of the seating portion 81 is more preferably in the range of 286 to 348 mm. In an example of the present embodiment, the entire length L1 of the seating portion 81 is 317 mm, and the total length L0 of the saddle 80 is 409 mm. Is set to

また、着座部８１は、１．５〜５歳の幼児が無理なく自然に跨れるように、後部寄りに最大幅Ｗが約１２０ｍｍの部分を配置し、この部分の幅が前方に行くにしたがって徐々に狭くなるようにしている   In addition, the seating portion 81 arranges a portion having a maximum width W of about 120 mm near the rear so that an infant of 1.5 to 5 years can naturally straddle naturally, and as the width of this portion goes forward, Gradually narrowing

着座部８１の表面は、凹凸のない略平坦状に形成され、図示例について詳細に説明すれば、車幅方向において中央部を上方へ突出させた凸曲面状であって、且つ前方へ連続し若干下り傾斜する面に形成される。   The surface of the seating portion 81 is formed in a substantially flat shape without unevenness, and if described in detail with reference to the illustrated example, the seating portion 81 has a convex curved shape with a central portion protruding upward in the vehicle width direction, and is continuous to the front. It is formed on a slightly inclined surface.

非着座部８２は、幼児が着座することのないように確保された部位であり、着座部８１よりも後側において後輪軸部６０を前後に跨る範囲に設けられる。
この非着座部８２には、着座部８１よりも上方へ突出する側面視略山形状の***部８２ａが設けられる。この***部８２ａの頂部は、後輪軸部６０の中心よりも前側に位置する。着座部８１は、この頂部よりも更に前側に位置することになる。 The non-seat portion 82 is a portion secured so that the infant does not sit, and is provided in a range that straddles the rear wheel axle portion 60 on the rear side of the seat portion 81 and back and forth.
The non-seat portion 82 is provided with a substantially mountain-shaped raised portion 82 a that projects upward from the seat portion 81. The top of the raised portion 82a is located forward of the center of the rear wheel axle 60. The seat 81 is located further forward than the top.

そして、上記構成の三輪車１は、左右の後輪７０，７０とサドル８０の最後端部８０ａとが略水平で平坦状な被載置面Ｘに三点で接触して自立するように（図７及び図８参照）、サドル８０の最後端部８０ａを後輪軸部６０よりも後方へ突出させている。   In the three-wheeled vehicle 1 having the above-described configuration, the left and right rear wheels 70, 70 and the rearmost end 80a of the saddle 80 come into contact with the substantially horizontal and flat mounting surface X at three points and become independent (see FIG. 7 and FIG. 8), the rearmost end portion 80a of the saddle 80 projects rearward from the rear wheel shaft portion 60.

次に、上記構成の三輪車１について、その特徴的な作用効果を詳細に説明する。
幼児は、サドル８０に着座する際、***部８２ａを有する非着座部８２を避けて、その前側の着座部８１に着座する。すなわち、幼児の着座位置を、着座部８１側へ自然に促すことができる。 Next, the characteristic operation and effect of the three-wheeled vehicle 1 having the above configuration will be described in detail.
When sitting on the saddle 80, the infant avoids the non-seat portion 82 having the raised portion 82a and sits on the front seat portion 81 on the front side. That is, the seating position of the infant can be naturally urged toward the seating portion 81 side.

また、着座部８１には、前側着座領域８１ａ及び後側着座領域８１ｂが、前後方向へわたって比較的長く確保される。
このため、例えば、低年齢で体格の小さい幼児は、図５（ａ）に示すように、着座部８１の前側着座領域８１ａに着座し、足をペダル３１に掛けたり、足で床を蹴ったり等の動作を自然に行うことができる。
また、高年齢で体格の大きい幼児は、図５（ｂ）に示すように、着座部８１の後側着座領域８１ｂに着座するため、比較的長い脚部を余らせることなく、足をペダル３１に掛けたり、足で床を蹴ったり等の動作を自然に行うことができる。 In the seating portion 81, a front seating region 81a and a rear seating region 81b are secured relatively long in the front-rear direction.
For this reason, for example, as shown in FIG. 5A, a young child with a small age and a small physique sits on the front seating area 81a of the seating portion 81 and puts his / her foot on the pedal 31 or kicks the floor with his / her foot. And the like can be performed naturally.
In addition, as shown in FIG. 5 (b), an infant of a large age and having a large physique sits on the rear seating area 81b of the seating section 81, and thus can use the pedal 31 without leaving a relatively long leg. And the floor can be naturally kicked with the feet.

しかも、前後に変化する着座加重を後輪軸部６０よりも前側で受けるようにしているので、例えば重量バランスの後方への偏りによって前輪３０が浮くようなこともなく、走行状態を安定させることができる。   In addition, since the front and rear seating weights, which change back and forth, are received on the front side of the rear wheel shaft portion 60, the front wheels 30 do not float due to, for example, a rearward bias of the weight balance, and the running state can be stabilized. it can.

また、後側着座領域８１ｂ側を、上方斜め前方へ傾いた後フレーム部５０等によって頑強に支持しているため、体格の大きな幼児の着座により比較的大きな重量が加わった場合でも、各部の破損や変形等を効果的に防ぐことができる。   Further, since the rear seating area 81b side is strongly supported by the rear frame portion 50 inclined obliquely upward and forward, the respective portions may be damaged even when a relatively large weight is added by the seating of a large physique infant. And deformation can be effectively prevented.

また、三輪車１を収納する際には、図６に示すように、保護者等が一方の手で操作部１７ａを引きながら、他方の手で前フレーム部２０側を下方へ折り込むようにすれば、第一の折曲機構Ａによって、第一の枢支部ａ１よりも前側の部分（前側部位１１ａ、前フレーム部２０及びハンドル部４０及び前輪３０等）が回動して、前輪３０が、サドル８０と後フレーム部５０がなす内角側の空間Ｓ１に入り込む。
このため、三輪車１をコンパクトな収納態様にすることができる。 When the tricycle 1 is stored, as shown in FIG. 6, a parent or the like may pull the operation unit 17a with one hand and fold the front frame 20 side downward with the other hand. By the first bending mechanism A, a portion (the front portion 11a, the front frame portion 20, the handle portion 40, the front wheel 30, etc.) on the front side of the first pivotal support portion a1 is rotated, and the front wheel 30 is It enters the space S1 on the inner angle side formed by the rear frame portion 50 and the rear frame portion 50.
For this reason, the three-wheeled vehicle 1 can be made into a compact storage mode.

なお、操作部１７ａがサドル８０の着座部８１よりも後側に位置するため、着座部８１に跨って前方を向いた幼児が、走行中等に誤って操作部１７ａを操作してしまうようなことを防ぐことができる。   In addition, since the operation part 17a is located behind the seating part 81 of the saddle 80, an infant who is directed forward across the seating part 81 may operate the operation part 17a by mistake during running or the like. Can be prevented.

また、前記収納態様において、後輪７０，７０とサドル８０の最後端部８０ａとを地面や床面等の被載置面Ｘに三点で接触させて、当該三輪車１全体を自立させることができる（図７及び図８参照）。このため、三輪車１を、転動防止した状態で、水平面積の比較的小さい被載置面Ｘに載置することが可能である。
さらに、ハンドル部４０を後方へ回動させるようにして、前フレーム部２０を折り畳めば、高さ寸法が小さくなり、よりコンパクトな収納態様にすることができる。 In the storage mode, the rear wheels 70, 70 and the rear end portion 80a of the saddle 80 are brought into contact with the mounting surface X, such as the ground or the floor, at three points, so that the entire tricycle 1 can be self-standing. (See FIGS. 7 and 8). For this reason, the tricycle 1 can be mounted on the mounting surface X having a relatively small horizontal area in a state in which rolling is prevented.
Further, if the front frame portion 20 is folded so that the handle portion 40 is rotated backward, the height dimension is reduced, and a more compact storage mode can be achieved.

本発明は上述した実施態様に限定されず、本発明の要旨を変更しない範囲で適宜変更可能である。   The present invention is not limited to the above-described embodiment, and can be appropriately changed without changing the gist of the present invention.
