DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiments do not limit the present invention.
[0010]
FIG. 1 is an overall view of a cart vehicle to which a steering shaft of the present invention is applied. This cart vehicle is for two people, but is not limited to this.
[0011]
In this cart vehicle, two seats of a front seat 12 and a rear seat 14 are fixed to a pipe body frame 10, and a power unit 16 in which an engine and a transmission are integrated is arranged behind the front seat 12. The On both the left and right sides of the rear end portion of the pipe body frame 10, rear wheel shafts are supported by bearings disposed in the mount plate.
[0012]
As shown in FIG. 2, the front wheel 40 is supported at the front end of the vehicle body frame 10 via a steering mechanism 18 including tie rods 34 and 36 and a knuckle arm 38.
[0013]
In the illustrated cart vehicle, the seats 12 and 14 are disposed obliquely with respect to the longitudinal direction of the vehicle body so that the operation can be performed on any of the seats 12 and 14, and steering is performed in front of the respective seats 12 and 14. Shafts 20 and 22 are disposed.
[0014]
As shown in FIGS. 2 to 4, the steering shafts 20 and 22 are formed in a pipe shape. In this case, the upper shafts 20A and 22A and the lower shafts 20B and 22B are bent so that they can be bent in the middle thereof. Composed. A steering handle 24 is detachably connected to one steering shaft 20 or 22, and a dummy handle 26 is detachably connected to the other steering shaft 20 or 22.
[0015]
As shown in FIG. 8, the steering handle 24 has an upper portion of a substantially circular wheel body 24a cut out, and both ends thereof are connected to a string-like rod 24b. A lever 27 and a brake lever 28 are attached. Each accelerator lever 27 and brake lever 28 are rotatable around an axis perpendicular to the rod 24b, and are substantially parallel to the wheel body 24a, with respect to the surface formed by the wheel body 24a. Thus, the gripping portions of the levers 27 and 28 are moved in parallel in the contact / separation direction. Thus, even a powerless driver can fully operate the accelerator lever 27 or the brake lever 28. The accelerator lever 27 is connected to the power unit 16 by a flexible tube, and the brake lever 28 is connected to a brake provided on the rear wheel by a flexible tube via a master cylinder.
[0016]
The steering handle 24 and the steering shaft 20 or 22 are connected via a connector (coupling portion) 30 so as to be integrally rotatable and detachable. The connector 30 can have an arbitrary configuration, but can be configured by a connector member 30A and a connector member 30B as shown in FIGS. One connector member 30 </ b> A has an inner tube 30 a and an outer tube 30 b, and the inner tube 30 a is integrally fixed to the shaft portion of the steering handle 24. The inner tube 30a is connected to the other connector member 30B integrally formed on the steering shaft 20 or 22 or fixed integrally by serration coupling or spline coupling so as to be integrally rotatable. One connector member 30A and the other connector 30B are connected by a so-called one-touch release method, and a plurality of locking bodies 30c that can be projected and retracted in the radial direction from the inner peripheral surface of the inner tube 30a of one connector member 30A are arranged in a plurality. The locking body 30c can be fitted into an annular groove 30d formed on the outer peripheral surface of the other connector member 30B. When the other connector member 30B is inserted into one connector member 30A, the connector member 30B advances while pushing the locking body 30c in the outer diameter direction (FIG. 6). And the latching body 30c opposes the urging | biasing force of the spring 30e provided in the outer peripheral surface of the inner pipe | tube 30a, and is fitted in the annular groove 30d, after retract | saving in an outer diameter direction (FIG. 7). Thus, the axial coupling between the two is ensured. Further, when removing, the locking body 30c is retracted in the outer diameter direction by pulling one connector 30A from the other connector 30B while moving the outer tube 30b of one connector 30A relative to the inner tube 30a. The one connector 30A is separated from the other connector 30B. Thus, the steering wheel 24 is simply removed from or attached to the steering shafts 20 and 22 by the connector 30 so that the rotation from the steering handle 24 is transmitted to the steering shafts 20 and 22 and by a so-called one-touch release method. be able to.
[0017]
One dummy handle 26 is a simple wheel without an accelerator lever or a brake lever. The dummy handle 26 and the steering shaft 20 or 22 are coupled via a connector (coupling portion) 30 so as to be freely rotatable and detachable. The structure of the connector can be exactly the same as that of the connector 30 in the case of the steering handle 24, but the inner tube 30a of the connector member 30A is different only in that it can be freely attached to the dummy handle 26. Accordingly, the dummy handle 26 can be freely rotated with respect to the steering shaft 20 or 22 by the connector 30, and the dummy handle 26 can be easily detached from or attached to the steering shaft 20 or 22 by a so-called one-touch release method. It can be done.
[0018]
The upper shafts 20A and 22A of the respective steering shafts 20 and 22 are transmitted to the lower shafts 20B and 22B by a universal joint, and the upper shafts 20A and 22A are transmitted to the lower shafts 20B and 22B. It can be bent. Under normal conditions, the upper shafts 20A and 22A are rotatably supported by the support pipe by a support pipe extending from the vehicle body. The lower shafts 20B and 22B that are the bases of the steering shafts 20 and 22 are connected to each other by tie rods 34, and the lower shafts 20B and 22B are connected to knuckle arms 38 and 38 by tie rods 36 and 36, respectively.
[0019]
In the cart vehicle configured as described above, the steering handle 24 is connected to either the steering shaft 20 or 22, while the dummy handle 26 is connected to the steering shaft 20 to which the steering handle 24 is not connected. 22 is connected. A seat corresponding to the steering handle 24 becomes a driver's seat, and a person seated in the driver's seat can hold the steering handle 24 to steer and operate the accelerator lever 27 and the brake lever 28 as appropriate. Acceleration / deceleration operations can be performed and driving can be enjoyed.
[0020]
On the other hand, the seat corresponding to the dummy handle 26 becomes a boarding seat, and a person sitting on the boarding seat can catch the dummy handle 26 and enjoy riding. At this time, since the rotation of the dummy handle 26 is not transmitted to the steering shaft 20 or 22, even if the dummy handle 26 is rotated, there is no problem in driving.
[0021]
Next, when a person sitting in the passenger seat wants to drive, the steering handle 24 and the dummy handle 26 are detached from the steering shaft with a single touch, and the steering handle 24 is attached to the corresponding steering shaft with a single touch to exchange the handle. . As a result, the person sitting on the seat can immediately drive.
[0022]
Since the seats 12 and 14 are disposed obliquely with respect to the longitudinal direction of the vehicle body, the field of view is not obstructed by the seats 12 and 14 and the seats 12 and 14 are not arranged in parallel. Even if you sit and drive at 12, 14, you can enjoy the same feeling as a single person.
[0023]
In this way, driving can be changed easily without getting on and off, so that a wide range of people, including those with reduced limbs, can enjoy driving and boarding.
[0024]
【The invention's effect】
As described above, according to the present invention, the steering handle and the dummy handle can be removed from the steering shaft, exchanged, and attached to another steering shaft, so that the driver's seat can be changed without moving. The driving can be changed. Thus, since it is not necessary to get on and off when changing driving, it has an excellent effect that even people who have difficulty getting on and off can enjoy driving freely.
