(B) The front and rear frames supporting the front and rear wheels are fastened to each other when the body frame is folded. (C) The fastening mechanism cannot be released unless a fastening release operation is performed.
The folding motorcycle has the following requirements.
(A) The folding motorcycle is an electric motorcycle that drives a rear wheel by a motor. (B) The fastening mechanism can be unlocked with the same key as a key for power ON / OFF.
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows a folding two-wheeled vehicle according to the present invention. In this two-wheeled vehicle, it is possible to arbitrarily select between a case where the motorcycle is manually driven by depressing a pedal 1 and a case where the motorcycle is electrically operated by operating a motor 2. The vehicle body frame 3 is divided into a front frame 4 and a rear frame 5 so that it is easy to handle when not in use or when being transported, and the front frame 4 and the rear frame 5 are hinged together. It is connected so that the body frame 3 can be folded in two around the hinge 6 (see FIG. 2).
[0009]
In this folding motorcycle, when a key a is inserted into a power lock 11 disposed on the right side of a handlebar 10 and turned on, the motor 2 operates, and when the accelerator lever 12 is operated, the speed can be adjusted. When the lever 13 is pulled, the front wheel 14 can be braked. When the grip 16 disposed on the left side of the handle 10 is turned, the transmission gear 18 of the rear wheel 17 is switched to adjust the speed, and when the brake lever 19 is pulled, the rear wheel 17 is braked. I have.
[0010]
Reference numeral 20 denotes a blinker switch for selectively lighting the blinker lamps 21a and 21b disposed on the left and right of the steering wheel and the blinker lamps 22a and 22b disposed on the left and right of the body frame. Reference numeral 23 denotes a stand. Reference numeral 24 denotes a lid that is opened when the battery 25 stored in the rear frame 5 is taken out. The lid 24 can lock and unlock the lid 26 with a key a for turning on / off the power lock 11.
[0011]
The body frame 3 is divided into two parts, a front frame 4 and a rear frame 5. A handlebar 10 and a front fork 28 supporting the front wheels 14 are turned around a head pipe 27 provided at the front end of the front frame 4. The rear frame 5 is movably supported, and the rear frame 5 has a pedal 1 for stepping, a motor 2 for power, a battery 25, a rear wheel 17, and a drive mechanism for driving the chain 7 using the motor 2 as power to rotate the rear wheel 17. 8 are provided.
[0012]
When the body frame 3 is bent into two, the front frame 4 and the rear frame 5, with the hinge 6 as a fulcrum, the front wheel 14 and the rear wheel 17 are opposed to each other. At 29, the front frame 4 and the rear frame 5 can be locked in a continuous state.
[0013]
The folding motorcycle is provided with a fastening mechanism A for fastening the front frame 4 (the front fork 28) and the rear frame 5 when the front frame 4 and the rear frame 5 are bent with the hinge 6 as a fulcrum. .
[0014]
As shown in FIG. 3, the fastening mechanism A includes a lock bolt 30 attached to the tip of the front fork 28 and a lock portion 40 attached to the tip of the rear frame 5, and the lock bolt 30 is folded when folded. The tip of the lock bolt 30 can be inserted into the lock portion 40 so as to face the lock portion 40.
[0015]
As shown in FIG. 4, the lock bolt 30 has a locking portion 31 formed in a tapered frustoconical shape at a front portion, and a rear portion of a hub shaft 32 of a front wheel 14 attached to a front end of a front fork 28. A screw hole is formed to be screwed into a screw groove formed at the tip, and can be fixed to the front fork 28 by being screwed into the tip of the hub shaft 32.
[0016]
The locking portion 40 can be fixed to the rear frame 5 by screwing the fixing plate 41 to the rear frame 5. The fixing plate 41 has a cylindrical bolt receiver 42 formed therein. 42 is provided with a lock mechanism B. If the lock mechanism B is constituted by a well-known lock mechanism in which the lock claw 44 protrudes into the bolt receiver 42 when the lock button 43 is pushed in, and the protruding state is maintained unless the lock c is unlocked by the key a. Good.
[0017]
As shown in FIGS. 5A and 5B, the tip of the lock bolt 30 is inserted into the bolt receiver 42, and the lock button 43 is pushed in, so that the lock claw 44 projects and locks the lock portion 31 of the lock bolt 30. As a result, the fastening state between the front frame 4 (the front fork 28) and the rear frame 5 is established. Unless the lock button 43 is unlocked with the key a, the lock bolt 30 does not come out of the bolt receiver 42, so that the fastening state between the front frame 4 (front fork 28) and the rear frame 5 is consciously opened by the user. Unless locked, the fastening state will not be released.
[0018]
According to the above-mentioned folding motorcycle, the body frame 3 is divided into two frames of the front frame 4 and the rear frame 5 and is rotatably connected by the hinge body 6. The front frame 4 (front fork 28) and the rear frame 5 can be fastened by the fastening mechanism A at the time of folding. In this fastening mechanism A, the lock bolt 30 provided on the front fork 28 is inserted into a lock portion 40 provided on the rear frame 5 and the lock button 43 is pressed to lock the lock bolt 30 on the lock portion 40 and lock with the key a. The fastened state of the front frame 4 and the rear frame 5 is not released unless the locked state of the button 43 is released. Therefore, if the user does not lock intentionally, the fastened state will not be achieved. If you do not intentionally unlock in a, the fastening state will not be released, for example, when packing in a folded state to go to the suburbs for cycling, or when unloading from the car on site Even if external pressure is applied, the fastening state will not be released without permission, so it is possible to prevent accidents that may occur if the fastening is released during work beforehand Door can be.
[0019]
The key a for releasing the fastening uses the same key as the key used for the lid lock 26 provided on the lid 24 of the battery box and the power lock 11 provided on the handle 10. Does not need to manage a plurality of keys, and can simplify operation.
[0020]
【The invention's effect】
According to the first aspect of the invention, when the front frame and the rear frame are fastened by the fastening mechanism when the body frame is folded, the fastening state is released without permission unless the user intentionally releases the fastening. Therefore, there is no possibility that the fastening is released at the time of handling, and a folding bicycle that considers safety during handling can be provided.
[0021]
According to the invention of claim 2, when the folding motorcycle is an electric motorcycle that runs by using a motor as a power, a key for turning on / off the motor, a key for locking the lid of the battery, and a key for releasing the fastening are the same key. With this configuration, it is possible to reduce the number of keys possessed, and to realize a folding motorcycle that is easy to manage because it is not necessary to select keys at the time of use.
