  Hereinafter, preferred embodiments of an inverted moving body according to the present invention will be described in detail with reference to the drawings.

  As shown in FIGS. 1 to 3, the inverted moving body 1 is configured as an inverted two-wheeled vehicle that can perform desired traveling while maintaining an inverted state according to the movement of the center of gravity of the passenger. The inverted moving body 1 includes a column 2 that is erected on a cart (not shown) having wheels and a step base. A rail portion 3 extending in the vertical direction is fixed to the cylindrical column 2. The rail portion 3 is positioned on the front side of the support column 2 and is fixed to the support column 2 via a rail connecting member 4.

  The support column 2 is made of aluminum for weight reduction, and the rail portion 3 needs high-strength aluminum. However, since the high-strength aluminum material has poor weldability, it is difficult to weld the rail portion 3 directly to the support column 2. Therefore, the rail portion 3 is fixed to the support column 2 by welding with a long rail connecting member 4 made of aluminum suitable for welding.

  A block-like slider portion 6 is attached to the rail portion 3. The slider portion 6 includes a slider main body 10 to which the handle portion 7 is fixed, and a movable member 11 that can approach / separate from the slider main body 10. The base end 10a side of the slider main body 10 is screwed to the lower end of the handle portion 7, and the movable member 11 is accommodated in a notched or concave movable member accommodating portion 10R formed in the slider main body 10.

  A first clamp half 10A that is pressed against the rail portion 3 from one side is provided on the distal end side of the slider body 10, and the distal end side of the movable member 11 is also on the other side with respect to the rail portion 3. A second clamp half 11A that is pressed from one side is provided. The first clamp half 10A and the second clamp half 11A constitute a clamp 12 that clamps / releases the rail 3 and the first clamp half 10A and the second clamp half 11A. When the rail portion 3 is sandwiched in cooperation with the slider portion 6, the slider portion 6 is fixed at a predetermined position.

  The first clamp half 10A is formed with a first clamp recess 10S for inserting one side of the rail part 3 having a barrel shape in cross section, and the second clamp half 11A is provided with the rail part 3 A second clamp recess 11S for inserting the other side is formed. The wall surface 10b that forms the first clamp recess 10S is in surface contact at two places before and after the rail portion 3, and similarly, the wall surface 11b that forms the second clamp recess 11S also faces at two places before and after the rail portion 3. Contact (see FIG. 4).

  In addition, excessive surface contact may increase the sliding resistance of the slider portion 6 with respect to the rail portion 3, and the slider portion 6 may not be able to move smoothly. Therefore, in order to avoid excessive surface contact on the column 2 side of the first and second clamp halves 10A and 11A, cut portions 10c and 11c are formed on the wall surfaces 10b and 11b.

  The base end of the movable member 11 is supported by a shaft portion 13 fixed to the slider body 10, and this shaft portion 13 is disposed in the movable member housing portion 10 </ b> R, and the movable member 11 is in a horizontal plane with the shaft portion 13 as a center. To rotate. Thereby, the interval between the first clamp half 10A and the second clamp half 11A can be widened or narrowed. Such an operation is performed by the operation unit 20.

  The operation unit 20 includes a shaft 21 that penetrates the rail unit 3 and the shaft unit 13 in the horizontal direction, and a clamp lever 22 disposed at an end of the shaft 21. A double nut 23 is screwed to one end of the shaft 21, and a clamp lever 22 is attached to the other end of the shaft 21 via a cam mechanism so as to be rotatable in the horizontal direction. The head 21a of the shaft 21 and the double nut 23 are tightened so as to bring the slider body 10 and the movable member 11 closer to each other. By tightening the clamp lever 22 90 degrees in the direction of the arrow, this tightening is performed. Loosely, the space between the first clamp half 10A and the second clamp half 11A slightly expands. Thereby, the slider part 6 can be freely slid along the rail part 3.

  This slider portion 6 enables pitch feed at regular intervals. The movable member 11 is provided with a positioning pin 24 that protrudes into the second clamp recess 11S. On the other hand, the rail portion 3 is formed with positioning holes 25 that allow the positioning pins 24 to be inserted at predetermined intervals in the height direction.

  By inserting the positioning pin 24 into the positioning hole 25, even if the tightening force by the slider body 10 and the movable member 11 is somewhat loosened, the situation where the slider portion 6 falls along the rail portion 3 is prevented. can do. When the clamp lever 22 is operated, the space between the first clamp half 10A and the second clamp half 11A expands, so that the positioning pin 24 comes out of the positioning hole 25. In this state, the slider portion 6 can be moved up and down along the rail portion 3.

  In the state in which the movement of the slider portion 6 is free, the positioning pin 24 needs to be reinserted into the positioning hole 25 in determining the position of the slider portion 6, that is, in determining the height of the handle portion 7. Therefore, in order to avoid the position adjustment of the slider portion 6 by visual observation of the positioning pin 24, the movable member 11 is provided with a latch portion 27 having a spring-biased ball 27a. When the ball 27a of the latch portion 27 is fitted into the positioning hole 25, the slider portion 6 can be temporarily locked. Then, the distance L1 between the centers of the ball 27a and the positioning pin 24 and the distance L2 between the centers of the positioning holes 25 are made the same so that the positioning pin 24 and the positioning pin 24 are fitted in the positioning hole 25. The alignment with the positioning hole 25 is automatically achieved. Thereby, the position of the slider part 6, that is, the height of the handle part 7 can be easily determined.

  In this inverted mobile body 1, the rail portion 3 is arranged on the support column 2 so as to extend along the support column 2, so that it is guided by the support column itself to move the slider unit up and down. Thus, the vertical movement of the handle portion 7 can be made less susceptible to the diameter and shape of the column 2. Thereby, even if various parts are mounted on the support column 2, the influence can be reduced. Since the rail portion 3 is employed, the height adjustment range of the handle portion 7 can be freely set by increasing or decreasing the length of the rail portion 3.
