Description

  The present invention relates to a self-propelled skateboard.

  In the past, most skateboards used an artificial slope such as a half-pipe and were repeatedly used for running, rotating, etc. while moving the center of gravity. Therefore, when moving on a flat place with little inclination, it is necessary to place one foot on the skateboard and clear the ground with the other foot. It took a great burden on the waist and was not practical.

  Therefore, an integrated board, traveling wheels connected to two or more places including the front and rear of the board, a driving mechanism for driving the wheels, and a driver's center of movement on the board are moved to correct the driving device. There has been proposed a self-propelled skateboard characterized by comprising means for controlling reverse rotation, stopping, advancing, retreating, and speed adjustment (see Patent Document 1). There is also a skateboard with a wheel drive pedal that the inventor has previously filed (see Patent Document 2).

JP 2003-237670 A Japanese Patent Laid-Open No. 2003-2276

  However, the self-propelled skateboard proposed in Patent Document 1 requires a driving device and various detection means on the board, is very expensive, and is used for a long time over a long distance. Has a problem that a spare power supply is required.

  Further, in the case of the skateboard with a wheel drive pedal proposed in the above-mentioned Patent Document 2, the skateboard can be run by a pedal operation of a skateboard user's foot, but on a gentle uphill, There is a possibility that a heavy load will be generated on the pedal, which may cause a burden on the foot, and because the mounting position of the user's foot is fixed, it is difficult to use depending on the user's body shape (height, foot length, etc.) There are also problems.

  The present invention has been made in view of the above problems, and does not require various detection means, power supply devices, etc., is inexpensive, and can be used by anyone without being restricted by the user's body shape, and has a low load. It is intended to provide a self-propelled skateboard that enables long-distance running for a long time.

  Therefore, the self-propelled skateboard of the present invention includes a skateboard plate, a plurality of wheel portions attached to a predetermined position below the skateboard plate, and a rotation transmission mechanism provided in any of the wheel portions, A plate-like first drive mechanism that is connected to the rotation transmission mechanism and is rotatably provided on the upper surface of the skateboard plate via a rotation shaft, and a rotating mechanism provided on the upper surface of the first drive mechanism. And a second driving mechanism having a pedal body provided on the upper surface of the first driving mechanism via the rotating mechanism and the drive transmission mechanism. This is the first feature.

  Further, the drive transmission mechanism is a belt body that connects a rotation mechanism provided through the rotation shaft and a second drive mechanism having the pedal body. .

  The third feature is that the drive transmission mechanism is a meshing mechanism that connects a rotation mechanism provided through the rotation shaft and a second drive mechanism having the pedal body. To do.

  In addition, the fourth feature is that the rotation transmission mechanism includes a ratchet mechanism.

  Further, the second feature is that the second drive mechanism and the rotation mechanism include a ratchet mechanism.

  According to the self-propelled skateboard according to the present invention, the user selects two types of drive mechanisms and operates with his / her foot so that the user can ride on the skateboard without kicking the ground with one foot for a long time. It has an excellent effect of being able to travel.

  Further, the plate-like first driving mechanism can be rotated by operating a foot, and the rotating mechanism can be rotated via a second driving mechanism provided on the upper surface of the first driving mechanism. Therefore, since the operation can be performed with less load without operating the pedal body, the user can easily run the skateboard even on a gentle uphill.

  Further, since the rotation transmission mechanism or the second drive mechanism and the rotation mechanism include a ratchet mechanism, the rotation of the wheel portion of the skateboard is not transmitted to the first drive mechanism or the second drive mechanism. Therefore, it has an excellent effect of being safe.

  Hereinafter, the best mode for carrying out the present invention will be described based on an embodiment shown in the drawings, but it is needless to say that the present invention is not limited to this embodiment. FIG. 1 is a perspective view showing an embodiment of a self-propelled skateboard according to the present invention, and FIG. 2 is a longitudinal sectional view of FIG. 3 is a partially cutaway explanatory view of FIG. 1, and FIG. 4 is a perspective view showing another embodiment of the self-propelled skateboard according to the present invention.

  As shown in FIGS. 1 to 3, a self-propelled skateboard 1 according to the present invention includes a plurality of wheels 10 provided at a lower portion of a skateboard plate 2 and a gear portion provided near an axle 12 of the wheels 10. 11 and a gear 9 that meshes with the gear portion 11 and passes through the rotating shaft 8, and the wheel 10 is a bearing 13 provided at the approximate center of the axle 12 and a column attached via the bearing 13. 14 is rotatably attached to the lower portion of the skateboard plate 2, and the rotation shaft 8 is rotated by the rotation of a drive mechanism (drive plate 3, belt wheel 5, 6, belt 7) described later. As the gear 9 connected to the wheel rotates, the wheel 10 rotates and can travel.

  The rotation shaft 8 is inserted through the belt wheel 5 through the skateboard plate 2 and the drive plate 3, and the belt wheel 5 is connected to the belt wheel 6 having the pedal 4 via the belt 7. Further, the rotation shaft 41 of the belt wheel 6 is inserted into a predetermined position of the drive plate 3, and the belt wheel 6 is rotatable on the drive plate 3. In this configuration, when the user of the skateboard rotates the belt wheel 6 with the foot through the pedal 4, the rotation of the belt wheel 6 rotates the belt wheel 5 through the belt 7 and further rotates with the belt wheel 5. As described above, the wheel 10 is rotated by the rotation of the gear 9 connected by the moving shaft 8. Here, the belt wheel 5 has a ratchet mechanism in advance to prevent the belt wheel 5 from rotating in conjunction with the rotation of the wheel 10, and for example, the belt wheel 5 rotates clockwise. When the wheel 10 rotates and moves forward, even if the belt wheel 5 is rotated counterclockwise, the belt wheel 5 is idled and no counterclockwise action is transmitted to the wheel 10.

  Next, a method of using the self-propelled skateboard 1 according to the present invention will be described with reference to FIG. 3. Regarding a method for a skateboard user to run the self-propelled skateboard 1 by turning the pedal 4 with one foot. As described above. When driving the self-propelled skateboard 1 using the drive plate 3, the user rides on the skateboard plate 2 with both legs and presses the pedal 4 and the belt wheel 6 against the drive plate 3 with one foot to rotate. The drive plate 3 is rotated around the rotation shaft 8. Here, the belt wheel 6 fixed to the driving plate 3 is connected to the belt wheel 5 via the belt 7, and the belt wheel 5 also rotates as the driving plate 3 rotates. When the belt wheel 5 rotates, the wheels 10 also rotate as described above, and the self-propelled skateboard 1 travels. Here, the drive plate 3 does not need to be rotated 360 degrees, but is rotated 90 degrees clockwise, for example, by a ratchet mechanism (not shown) of the belt wheel 5 and then counterclockwise 90. The clockwise rotation is transmitted to the belt wheel 5 by repeating the rotating operation. Moreover, since there is an appropriate distance between the rotation shaft 8 and the drive plate 3 on which the foot is placed, the drive plate 3 can be rotated with a small load by the principle of the lever. The person can easily run the self-propelled skateboard 1. In the present embodiment, the ratchet mechanism is described as being provided in the belt wheel 5, but it may be provided in the gear 9. Further, since the drive plate 3 is rotatable, the user may rotate the belt wheel 6 simultaneously with the rotation of the drive plate 3, depending on the user's body shape (height, foot length, etc.). It may be selected as appropriate, and may be provided with a fixture for fixing the drive plate 3 at a predetermined position as necessary.

  Next, another embodiment of the self-propelled skateboard 1 according to the present invention will be described with reference to FIG. As shown in the figure, on the skateboard plate 2, a drive plate 3, a gear 15, a gear 16 that meshes with the gear 15, and a pedal 4 provided on the gear 15 are configured. The arrangement of the wheels 10 and the like below the skateboard plate 2 is substantially the same as the embodiment shown in FIGS. 1 and 2, but the rotation direction is opposite to the drive transmission by the belt 7, The mounting position of the wheel 10 provided with the gear portion 11 that meshes with the gear 9 is a position facing the embodiment.

  When the self-propelled skateboard 1 having this configuration is used, the user rides the skateboard plate 2 with both legs and rotates the pedal 4 with one foot to rotate the gear 15. The gear 16 that meshes with the gear 15 rotates in the opposite direction to the rotation of the gear 15, and the gear 9 and the wheel 10 rotate through the rotation shaft 8 that passes through the gear 16 so that the skateboard 1 can travel. It becomes possible. Moreover, when using the drive plate 3, it is the same as that of the Example which uses the belt wheel mentioned above, and abbreviate | omits. In this configuration, the gear 14 and the gear 15 are each provided with a ratchet mechanism (not shown), and the rotation direction can be set by setting the ratchet mechanism, and the rotation of the wheel 10 is transmitted to the gear 15. To prevent it.

  As described above, according to the self-propelled skateboard according to the present invention, the user selects two types of drive mechanisms and operates with his / her foot so that the user can ride on the skateboard without kicking the ground with one foot for a long time. The skateboard can be easily driven even on a gentle uphill, and the ratchet mechanism is included so that the wheels can be rotated. Since it is not transmitted to the drive mechanism, a safe skateboard can be provided.
