[0022] As shown in Figs. 4 (B) and (C), the idler gear 25 and the second switching gear 35 provided on the main body frame do not swing, so that they can be swung to avoid interference with the swing frame 21. It is located in a slit 21s formed in the frame 21.

[0023] [Inclined plate 5]

As shown in FIGS. 2A and 2B, the inclined plate 5 includes a rectangular plate 47 disposed obliquely and a triangular plate 49 disposed in a gap between the rectangular plate 47 and the ground. Have. The rectangular plate 47 has a width that allows one wheel 11 of the driving wheels 9 of the automobile to pass over. The inclined plate 5 is separate from the box-shaped main body nosing 7, and can be installed in contact with the front vertical surface 51A or the rear vertical surface 51B of the main body nosing 7. The installation direction can be changed to either the roller 13A side or the 13B side of the pair of rollers 13. The inclined plate 5 is divided by a central dividing wall 53 in the front-rear direction and can be folded by a hinge 54. By folding, the space between the pair of rollers 13 of the main body housing 7 is large enough to be accommodated.

[0025] (Function)

When generating electricity, take this device 1 out of the trunk of the car and place it on the ground on the drive wheel 9 side of the car. Place it on the front side if it is front-wheel drive, and place it on the rear side if it is rear-wheel drive. Then, the inclined plate 5 is taken out and spread out and installed on the vehicle side with respect to the apparatus body 3.

Next, the automobile is moved, and one wheel 11 of the drive wheel 9 passes over the inclined plate 5 and is placed on the apparatus main body 3.

At this time, as shown in FIG. 1 and FIG. 4 (A), when one wheel 11 is placed from the front side of the device (right side in the figure) and rides on the first roller 13A, it is as shown in FIG. 4 (B). The swing frame 21 having an upward-pointing character swings, and the right wing of the swing frame 21 sinks. Therefore, the first roller gear 23 and the first switching gear 29 on the right wing sandwich each other with the idler gear 25 interposed therebetween. Then, since the left wing is lifted, the second roller gear 33 and the center gear 27 are disengaged from the second switching gear 35.

In this way, the force of only the rotational force of the first roller 13A is transmitted to the drive shaft 15 of the generator via the first roller gear 23, the idler gear 25, the first switching gear 29, and the center gear 27. In addition, the other second roller 13B is lifted, so that the roller 13B in the forward direction in the overload direction is raised, and a stopper roller for stopping the one wheel 11 can be obtained.

[0028] Conversely, although not shown, when one wheel 11 is placed from the rear side of the device (left side in the figure) and rides on the second roller 13B, the swing frame as shown in FIG. 4 (C). 21 swings in the opposite direction, and the left wing of the swing frame 21 sinks. Therefore, the second roller gear 33 and the center gear 27 sandwich each other with the second switching gear 35 interposed therebetween. Then, since the right wing is lifted, the first roller gear 23 and the first switching gear 29 are disengaged from the idler gear 25.

As described above, the force is transmitted to the drive shaft 15 of the generator via the second roller gear 33, the second switching gear 35, and the center gear 27 only by the rotational force of the second roller 13B. In addition, the other first roller 13A is lifted, so that the roller 13A in front of the overloading direction is raised, and a stopper roller for stopping the one wheel 11 can be obtained. [0030] Further, the gear device 17 transmits only the rotational force of the roller 13A or 13B on which the single wheel 11 is mounted to the drive shaft 15 of the generator. When one roller is placed on one wheel 11, the swing frame 21 swings and the other roller is lifted. As a result, the front roller, which may be overloaded, is raised, and a stopper roller for stopping one wheel 11 can be obtained.

[0031] With the pair of rollers supporting the front side and the rear side of the single wheel 11, when the automobile is moved forward from the idling state, the drive wheel 9 is grounded by the action of the differential gear of the automobile. ! / Wheeling wheel does not rotate, and one wheel 11 that hits on the roller 13 of the device body 3 rotates. The drive shaft 15 of the generator is activated by the rotational force, and equipment such as an electric motor and an illuminator can be operated.

[Effect of the embodiment]

According to this embodiment, (1) the vehicle is moved and one wheel 11 of the drive wheels 9 is placed on the tilting plate 5 and used on the apparatus of this embodiment. Wheel 9 is grounded and therefore does not skid. In addition, since the inclined plate 5 is used, it is necessary to jack up the one wheel 11.

(2) Further, the width of the inclined plate 5 and the length of the roller 13 need only be sufficient for the one wheel 11 to pass or rest. In contrast to this, when both wheels of the drive wheel 9 are used as in Patent Documents 1 and 2, the pair of rollers 13 needs to have a vehicle width of the vehicle. Therefore, in this embodiment, the apparatus can be made compact and easy to carry in a narrow trunk of an automobile.

[0034] (3) The tilted plate can be used with the direction of installation with respect to the main body housing 7 being changed, and the gear device 17 can be used to mount the vehicle's one wheel 11 on the device with either side of the device main body 3. wear. Therefore, even if it is difficult to change the direction of the vehicle in a narrow place such as a mountain road, the alignment operation of the vehicle and the device can be easily performed without changing the direction of the device body 3 by 180 degrees, for example. The device is easy to use.

(4) When the device is not used, the inclined plate 5 can be accommodated between the pair of rollers 13 of the device body and the winging 7, and the device can be made compact. Easy to do.

[0036] (5) —One roller 13A or 13B of the pair of rollers 13A and 13B has one wheel 11 , The swinging frame 21 swings and the other roller 13B or 13A lifts up, raising the front roller 13B or 13A that may be overloaded, and stopping the one wheel 11 Can be a stopper roller. Therefore, when the single wheel 11 of the automobile is placed on the apparatus, the speed control power of the automobile can be facilitated so that both rollers 13A and 13B are not accidentally placed over the rollers 13A and 13B.

[0037] (6) —When one roller 13A or 13B of the pair of rollers 13A and 13B is placed on the one wheel 11, the swing frame 21 swings, and the roller gear of one sinking roller 13A or 13B And the roller gear 33 or 23 of the other lifted roller 13B or 13A is disengaged, so that only the rotational force of the roller 13A or 13B on which the one wheel 11 is mounted is automatically switched.

[0038] (7) The gear group of the gear device 17 can be a simple one in which six gears 23, 25, 29, 27, 35, 33 are arranged. That is, due to the existence of one idler gear 25, it is not necessary to change the rotation direction of the rotating part such as the drive shaft 15 of the generator or the hydraulic pump even if the automobile is mounted on the apparatus from either side of the apparatus. . In addition, the idler gear 25 and the second switching gear 35 are provided on the main body frame 7 so as to be stationary, and the other four gears are provided on the swinging frame 21 for swinging. It becomes possible.

[0039] "Other Embodiments"

In the above embodiment, the position of the peristaltic shaft 22 is the force that was located between the center gear 27 and the first switching gear 29 in FIGS. 4 (B) and 4 (C). It can be matched with the position of the center gear 27. In this case, since the drive shaft 15 of the generator in which the center gear 27 is provided coaxially is located at the center of the oscillation, the oscillation is small. In addition, the oscillating shaft 22 has a cylindrical shape that is concentric with the rotating shaft of the generator driving shaft 15 and is provided outside the rotating shaft so that the generator driving shaft 15 is not oscillated at all. It is also possible to do this.

In the above embodiment, the device that operates by the rotation of the drive wheel 9 is the drive shaft 15 of the generator. However, in another embodiment, a hydraulic pump may be used.

[0041] In the above embodiment, the gear ratio in the gear box 19 is constant, but in other embodiments, the gear ratio of the idler gear 25 and the center gear 27 in the gear box 19 is changed. A transmission gear mechanism can be employed. As a result, the gear ratio is changed after the initial operation so that the center gear 27 can be rotated more quickly, and therefore, it can be used in idling (creep phenomenon) of the automobile. Therefore, there is no need for a person who steps on the accelerator to speed up the rotation of the center gear 27. Therefore, the device can be used more safely. Brief Description of the Drawings
