It consists of a handle installed via a pulley in front, and is configured so that when the seater pulls the handle, the wheel is driven in the forward direction, so the handle is similar to rowing the oars of a ship. It moves forward by reciprocating. Rowing is an exercise that uses not only the arms but also the back muscles, so there is less fatigue in the arms even when traveling a longer distance than in the past, and because the boat does not bend forward, there is less fatigue due to unreasonable posture. Furthermore, since it has a simple structure consisting of a sprocket and one clutch, maintenance is also easy.

A wire 13 is passed through. wire 1
A chain 14 is connected to one end of the main wheels 3, and transmits driving force to a sprocket 15 that is interlocked with each main wheel 3. Sprocket 15 has one clutch 16
is built-in, wire 13 and chain 14
The main wheel 3 is driven in the forward direction by rotation due to the reciprocating motion of the main wheel 3.
tell to. An elastic member 17 made of a rubber rope is connected to the other end of the chain 14 and is passed along the handle 9 to return the wire 13 and chain 14 pulled by the handle 10 to their original standby position. .
Note that 19 is a buffer cap placed at the tip of the elbow pad, which buffers the impact on the obstacle when the elongated elbow pad hits the obstacle.

この回転のうち前進方向の回転を主車輪３に伝
え、それによつて主車輪３は前進方向に回転す
る。 The drive of the present invention will be explained. As shown in Figure 2,
When a person sits on seat 2 and pulls the handle 10 towards him like rowing a boat's oar (solid line arrow in the figure),
The wire 13 whose one end is connected to the handle 10 is the first
It is pulled upward by the sprocket 15 via the pulley 11 and the second pulley 12. wire 13
The chain 14 connected to the other end is the wire 13
Following this, the sprocket 15 is rotated. One clutch 16 built into the sprocket 15 transmits the rotation in the forward direction to the main wheel 3, thereby causing the main wheel 3 to rotate in the forward direction.
次に引手１０を引き寄せる力をなくすと、チエ

１７が縮まり（図中、破線矢印）、チエーン１４、
ワイヤ１３、引手１０を元の待機位置に戻す。こ
の時、チエーン１４はスプロケツト１５に先程と
逆の回動を与えるが、一方クラツチ１６によつ
て、スプロケツト１５の回動を空転させて主車輪
３へ伝えない。 Next, when the force that pulls the handle 10 is removed, the elastic member 17, which was connected to the other end of the chain 14 and stretched, contracts (indicated by the broken line arrow in the figure), and the chain 14,
Return the wire 13 and handle 10 to their original standby positions. At this time, the chain 14 applies rotation to the sprocket 15 in the opposite direction, but on the other hand, the clutch 16 causes the rotation of the sprocket 15 to idle and is not transmitted to the main wheel 3.
以上のように、引手１０を引き寄せたり、離し
たりすることにより、主車輪３は前方へ回転する
ことになる。引手１０を引き寄せる運動は、腕だ
けでなく背筋も使用するため、従来の腕だけによ
る車輪の回動よりも疲れることなく、また前屈み
にならず、疲れも非常に少ないものとなる。 As described above, by pulling the handle 10 closer or releasing it, the main wheel 3 rotates forward. The movement of pulling the pull handle 10 uses not only the arms but also the back muscles, so it is less tiring than the conventional turning of the wheel using only the arms, and the user does not have to bend forward, resulting in very little fatigue.
なお、本実施例では、弾性部材１７はゴムロー
プとしたが、バネでもよい。 In this embodiment, the elastic member 17 is a rubber rope, but it may also be a spring.
また、両車輪を各々駆動する構造としたため、
方向転換の際には、例えば右に曲る際には、右の
ブレーキ機構７を作動させ、左の引手１０の操作
によつて左側の駆動部を前記に示した通り駆動さ
せることにより、容易に右へ方向転換する。左に
曲る際には、これと逆の操作を行えばよい。 In addition, since it has a structure in which both wheels are driven individually,
When changing direction, for example, when turning to the right, the right brake mechanism 7 is activated and the left drive unit is driven as described above by operating the left handle 10, thereby making it easier. Turn to the right. When turning left, just do the opposite.
尚、両車輪を各々駆動する構造としたが、駆動
系を左右共通にし、両車輪を共通の車軸によつて
連結し、別に例えば自動車の操向ハンドルのよう
な構造を前方の補助車輪４に備えて、方向変換の
ために補助車輪の向きを左右連動して変えるよう
にしてもよい。第３図はその実施例を示す横断面
図であり、第４図はその駆動を示す説明図であ
る。 Although the structure is such that both wheels are driven individually, the drive system is made common to the left and right, and both wheels are connected by a common axle. In order to change the direction, the direction of the auxiliary wheels may be changed in conjunction with the left and right wheels. FIG. 3 is a cross-sectional view showing the embodiment, and FIG. 4 is an explanatory diagram showing its driving.
図において、２２は、補助車輪４の向きを左右
連動して変えるハンドルである。この例において
も、前記の通り、利き手側の引手１０の直線往復

０に伝える。両主車輪３は別の一方クラツチ２１
を介して車軸２０に各々軸支されており、車軸の
前記前進方向の回転をこれら一方クラツチ２１に
より主車輪３に伝えるようになつている。これら
別の一方クラツチ２１は、左右に方向転換する際
に、左右の主車輪間の速度差に伴なう主車輪３の
回転差を解消する。 In the figure, 22 is a handle that changes the direction of the auxiliary wheels 4 in conjunction with the left and right sides. In this example as well, as described above, the linear reciprocating motion of the handle 10 on the dominant side is converted into rotational motion by the sprocket 15, and the rotation in the forward direction is transferred to the axle 2 by the clutch 16.
Tell 0. Both main wheels 3 are connected to another clutch 21
The two clutches 21 are respectively pivotally supported by the axle 20, and rotation of the axle in the forward direction is transmitted to the main wheel 3 by means of these one-way clutches 21. These other one-way clutches 21 eliminate the difference in rotation of the main wheels 3 due to the speed difference between the left and right main wheels when changing direction from side to side.
この第４図の例においては、駆動部（チエーン
１４とスプロケツト１５）を左右両側に設けた
が、これらはいずれか一方のみとしても差支えな
い。 In the example shown in FIG. 4, the drive parts (chain 14 and sprocket 15) are provided on both the left and right sides, but they may be provided on either one.

スも簡単ですむ。[Effect of the invention] As explained above, the first invention of the present application, as a driving means for driving the wheels, includes a linear chain that transmits the drive to the sprocket, an elastic member connected to one end of the chain, and other parts of the chain. The handle is connected to the end and installed via a pulley in front of the seater, and the handle is configured to drive the wheels in the forward direction when the seater pulls the handle. It moves forward by moving back and forth like rowing a ship's oars. Rowing is an exercise that uses not only the arms but also the back muscles, so there is less fatigue in the arms even when traveling a longer distance than in the past, and because the boat does not bend forward, there is less fatigue due to unreasonable posture. Furthermore, since it has a simple structure consisting of a sprocket and one clutch, maintenance is also easy.
