[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a caterpillar electric chair in which the running place of an electric car chair is limited to a substantially flat road, and the running place and range of use are expanded.

[0002]

[Prior art]

 Conventional electric car chairs run with three or four wheels, but it is difficult to get over even with small steps, and the weight of the power unit and battery has increased, so it took two adults to lift it. To do. Therefore, the driving place was limited to almost flat roads. In places that come into contact with history and nature, such as shrines and temples, nature trails and park river beds, there are usually steps, stairs, steep slopes, roads, gravel roads, etc. Rarely, it has been inconvenient to drive in these places with conventional electric wheelchairs.

[0003]

[Problems to be solved by the device]

 In this conventional type, people visiting shrines and temples, nature trails and parks, babbling riverbeds, and places that interact with history and nature have steps, stairs, steep slopes, ground roads, gravel roads, etc. Unless there was a great deal of help, I had no choice but to limit the location and range of use. The problem to be solved by this invention is to be able to run on these steps, steps, steep slopes, ground roads and gravel roads. Moreover, it should be compact and safe so that passengers can get on and off light vans and wagons.

[0004]

[Means for Solving the Problems]

 When you want to visit a nearby shrine or temple with an electric car chair, you will almost always encounter stone steps and stairs. If you want to go to the nature trails in the mountains or the murmuring of riverbed parks, you have to follow these steps, stairs, steep slopes, ground roads, and gravel roads. The inventor of this invention would not have enjoyed this much if the person who had to use an electric wheelchair could expand his or her range of motion and reach the edge of history and nature. As a result of careful consideration, we were able to complete this invention. The caterpillar electric chair according to the present invention is as follows. That is, in this caterpillar electric chair, as shown in FIGS. 4 and 5, the front chassis (1) and the rear chassis (2) are attached by joints (3) so that they can be bent up and down. Attach the power unit (4) to the rear chassis (2) independently to the left and right, and transmit power to the rear caterpillar (6) from the drive wheels (5) and power to the front caterpillar (7) from the drive wheels (8). is there. The chassis bending and stretching power (9) is attached to the joint part, and the arm (10) which is rotated by the power is joined to the vehicle body. When the arm (10) rotates, the vehicle body moves up and down, and the front and rear parts of the caterpillar rise and fall at an angle with respect to the road surface. A footrest (14) is provided in front of the vehicle body and a battery (15) is stored therein. It is equipped with a seat plate (16), a backrest (17), a handrail (18), a handrail bar (19), a control box (20), an emergency stop button (21), and a side mirror (22). It goes without saying that the control box is equipped with a sensor that detects the inclination of the vehicle body, and that the material and shape of the caterpillar are considered various.

[0005]

[Action]

 The body of the caterpillar electric chair is designed to be slightly long and thin in order to cope with the position of the center of gravity that changes when traveling on steps, stairs, steep slopes, ground roads, gravel roads, and the like. Normally, the car body is used in the upper position, and as shown in Fig. 4, the front and rear parts of the caterpillar are floated at an angle from the road surface, so it is easy to turn around and it is possible to get over a fairly large step. . In addition, since the center of gravity of the car body moves back and forth on stairs and steep slopes, the caterpillar increases the ground contact area in a straight line with respect to the road surface when the car body is used in the lower position as shown in Fig. 4, so stable climbing and descending slopes are possible. You can drive. In addition, it can be applied to various other rough roads, and as shown in the practical example 2, it is possible to drive carpets and soft tiles without scratches. The seat plate (16) can be opened and closed up and down to check and charge the battery. The handrail bar (19) is useful for transportation and support, and is equipped with a sensor that detects an automatic braking at the time of stop and an emergency stop button (21) and the inclination beyond safety. The backrest (17) can be reclining if necessary.

As a safety measure, it is equipped with a handrail (18), a handrail bar (19), an emergency stop button (21) and a side mirror (22), and a control box sensor is built in.

Practical example 2 FIG. 6 is a perspective view showing practical example 2. FIG. 7 is a plan view showing a practical example 2. 8 and 9 are side views showing the practical example 2. As shown in FIG. 7, the U-shaped rear chassis (2) and the front chassis (1) are jointed by the chassis bending / extending shaft (26) to which the driving wheels (8) (29) are attached. The power units (4) are independently mounted on the rear chassis (2) so that the drive wheels (5) transmit power to the rear caterpillar (6) and the drive wheels (8) transmit power to the front caterpillar (7). . As shown in FIG. 7, the free wheel (24) is attached to the tip of the U-shaped portion of the rear chassis. The vehicle bending and stretching shaft (26) is provided with the vehicle bending and stretching power (9), and the arm (10) that is rotated by the power is joined to the vehicle body. The vehicle body (11) is attached to the front and rear chassis with a rear joint groove (12) and a front joint shaft (13). When the arm (10) rotates, the vehicle body moves up and down, and the front and rear parts of the caterpillar rise and fall at an angle with respect to the road surface as shown in FIG. At that time, as shown in FIG. 8, when the chassis is straight to the road surface, the free wheels are slightly above the road surface. Further, when the vehicle body (11) is located above and the front and rear portions of the caterpillar float at an angle with respect to the road surface as shown in FIG. 9, the free wheels (24) contact the ground and the direction of the vehicle body is increased. Allows for easy turning. At this time, if the driving wheel (29) is made slightly smaller than the driving wheel (8) as shown in FIGS. 6 and 7, only the free wheels (24) and the caterpillars of the driving wheel (8) are in contact with each other and the four-wheel vehicle is You can drive like this. You can climb steep slopes and stairs by placing the car body in the lower position, and a small turn in the upper position, and you can turn the carpet and soft tiles in theaters and halls without scratching.

[Effect of device]

 The body of this caterpillar electric chair is designed to be slender in order to cope with the position of the center of gravity that changes when traveling on steps, stairs, steep slopes, ground roads, gravel roads, and the like. Normally, the car body is used in the upper position, and as shown in Fig. 4, the front and rear parts of the caterpillar are floated at an angle from the road surface, so it is easy to turn around and a fairly large step can be overcome. Also, since the center of gravity of the vehicle body moves forward and backward on stairs and steep slopes and becomes unstable, using the vehicle body in the lower position as shown in Fig. 4 causes the caterpillar to increase the ground contact area in a straight line with respect to the road surface. You can run downhill. As shown in FIGS. 4, 5, 8 and 9, the caterpillar's ground contact area is changed by bending the chassis up and down to allow running on steps, stairs, steep slopes, ground roads and gravel roads. As shown in Example 2, rugs and soft tiles can be run without scratches. As a safety measure, the power plant is equipped with an automatic brake, and an emergency stop button (21) side mirror (22) handrail (18) handrail bar (19) sensors for detecting leaning of the vehicle beyond safety are used. It is a compact caterpillar electric chair that is equipped and can get on and off light vans and wagons.
