る。BACKGROUND OF THE INVENTION Recently, the number of wheelchairs has greatly increased, and it has been occasionally seen that elderly and sick persons and disabled persons with leg disabilities go down the street in wheelchairs pushed by caregivers. However, as seen in wheelchair marathon competitions and summer / winter Paralympic competitions, many people with disabilities have more physical strength than ordinary people in wheelchairs. The number of these people is just the tip of the iceberg, and there is likely to be a great many socially disabled people behind them. One of the obstacles to these people's social activities is that there are steps on streets that cannot be moved up and down with conventional wheelchairs.
The steps on this street are being remodeled one after another, but it will probably be far away from the street. Therefore, in the present state, going out alone by a disabled person is equivalent to violence, and the appearance of a wheelchair capable of moving up and down steps quickly is desired.

る。However, since it is difficult to operate the four handles, it is necessary to connect the shafts of the front and rear auxiliary wheels to each other and fix them to the handle of each auxiliary wheel so as to have rigidity on the left and right sides, and to ignore some bending. Therefore, only one reduction gear is used for each of the front and rear wires, and therefore only two reduction gears are used. It is appropriate that the normal position of each auxiliary wheel during traveling is about 10 cm above the ground for both the front auxiliary wheel and the rear auxiliary wheel. The wire pulley incorporates a spring having a strength to raise the auxiliary wheel by about 60 degrees from a predetermined position in order to always maintain the tension of the wire rope.

必要である。Further, a rear auxiliary wheel is provided with a rotation function as an auxiliary moving device while the rear wheel is floating in the air. Considering that the moving distance is about 100 cm even if some extra space is added, a small wire drum with a diameter of about 7 to 8 cm is attached to the rear auxiliary wheel, and a wire rope of about 3 mm is wound around 5 to 6 times,
The end passes through the lower edge of the wire pulley of the rear auxiliary wheel, and is wound by a small wire drum winder with a crank handle attached to the lower front end of the armrest. Therefore, when the rider turns the steering wheel, the rear auxiliary wheel rotates,
The wheelchair moves forward when it lands. The wire drum for rotating the rear auxiliary wheel also has a built-in spring that winds up if the wire is loosened. In addition, two rear wheel brakes are arranged in one place so that the left and right wheels can be braked with one hand, and a parking brake is also necessary in consideration of a step on an inclined ground.

が、後方補助輪が後方に突き出ているので後方転倒する
事はない。[Function] When climbing up a step in a wheelchair, you must approach the step as much as possible, but people with leg disabilities may not be able to retract their feet. First, raise the front auxiliary wheel above the upper ground. Stop the wheelchair as close as possible without touching the steps. Next, by turning the handle of the reduction gear of the front auxiliary wheel, pulling the wire rope and pressing the front auxiliary wheel against the upper ground, the front wheel caster is lifted around the rear wheel axle and the passenger leans backward, but the rear The auxiliary wheels protrude rearward so that they do not fall backward.

から、ハンドリムで後輪を段差に当たるまで前進させら
れる。前進により前輪キャスターは上段地面に着地する
ので、前方補助輪は上げて後輪の持上げ操作の障害にな
らぬようにする。The front auxiliary wheel is pressed against the ground while raising the rear auxiliary wheel until the front wheel caster reaches the level of the upper ground. The rear auxiliary wheel is raised because the rear auxiliary wheel prevents rear rotation of the wheelchair. When the front wheel casters reach the level of the upper ground, the rear wheels remain on the lower stage, so the rear wheels can be advanced by the hand rim until they hit the step. Since the front wheel casters land on the upper ground by the forward movement, the front auxiliary wheels are raised so as not to hinder the lifting operation of the rear wheels.

そして走行の障害にならぬように後方補助輪を10cm
程度に上げる。Next, when lifting the rear wheels, the handle of the rear auxiliary wheel up / down reduction gear is rotated to push down the lower ground with the rear auxiliary wheels until the rear wheels reach the height of the upper ground. Even if the height of the upper ground is reached, the rear wheel can not move forward while suspended in the air, so rotate the handle of the winding machine at the lower part of the armrest and pull the rear auxiliary wheel rotating wire rope until the rear wheel rides on the upper ground . If the rear wheel lands on the upper ground and raises the rear auxiliary wheel, the wheelchair can move freely.
And the rear auxiliary wheel is 10cm so as not to hinder the running.
Raise to about.
【0011】段差を降りる場合は先ず前輪が段差から落

ことを確認して後輪で前進し、前輪を宙吊り状態にした
後、前方補助輪を巻上げて前輪が10cm程度下がった
時に一応前方補助輪の巻上げを停止する。When descending on a step, the front wheel approaches the step to the extent that the front wheel does not fall off the step, and lowers the front auxiliary wheel until it temporarily presses the lower ground. If it does not reach, this step is impossible to get down unless you have the skill and the help of a cane. After confirming that the front auxiliary wheel supports the weight of the front part of the vehicle, move forward with the rear wheel, suspend the front wheel in the air, then wind up the front auxiliary wheel and lower the front wheel by about 10 cm. Stop winding.
【0012】その理由は前輪の下降曲線が後輪の中心の

け、以後続いて後方補助輪のロープを緩め前輪より先に
後輪を一気に下段まで降ろし、次いで前方補助輪を巻き
上げて前輪を下段地面に着地させる。The reason for this is that the downward curve of the front wheel enters the lower side of the center of the rear wheel, and if the curve is further lowered, the front inclination angle suddenly increases and the vehicle may fall forward. In addition, 10c
The descending distance m varies depending on the distance between the front wheel and the rear wheel of the wheelchair. At this point, lower the rear auxiliary wheel to almost the upper ground,
Move the body forward with the hand rim, apply the rear wheel down from the step while applying the brake, apply the rear weight to the rear auxiliary wheel, then loosen the rope of the rear auxiliary wheel and lower the rear wheel at a stroke to the lower stage before the front wheel, Next, the front auxiliary wheel is wound up, and the front wheel is landed on the lower ground.
