Best Mode for Carrying Out the Invention
A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.
In a conventional single-seater bicycle 1 including a saddle 4 located in the middle of the bicycle body 10; a handle 3 located on a vertical hem portion; a front wheel 5, a rear wheel 5' ; chain gears 6, 6' located on the front wheel 5 and the rear wheel 5'; a chain 7 combined with the chain gears 6, 6'; and a pedal 8, the present invention provides a bicycle, which can be used for a two-seater bicycle by connecting and assembling a vertical hem portion of a special rear wheel 5a and body 10a and for the single-body bicycle by separating the rear wheel 5a and the body 10a.
The saddle 4a and handle 3a are respectively disposed on the special rear wheel 5a and the body 10a. In addition, a pedal 8a can be rotated by a chain 7a as chain gears 6a, 6a' are disposed.
In order to use the single-seater bicycle 1 as the two-seater bicycle la, two pieces of a connecting plate 13 is extended and formed on a vertical hem portion 10a of the body 10a of the rear wheel 5a so that it passes through an axis hole 14. In addition, a rotating body 16 having bearings 17, 17' is inserted and disposed in the inside of the axis hole 14 into a bearing axis 15 so that the rotating body 16 can be freely rotated on the bearing axis 15. In addition, a rotating pipe 8 is connected and fixed on the rotating body 16 by the connecting plate 9 in the outside of the rotating body 16 so that the rotating pipe 8 is inserted and connected to the fixing pipe 2 fixed on the rear end upper portion of the body 10 of the single-seater bicycle 1, inserting and connecting a ring-shaped ball bearing 20, 20' on an upper and lower portion.
In addition, as the present invention is one line and three wheel bicycle which the body 10a of the rear wheel 5a is connected and disposed on the single-seater bicycle 1, it can be used as the two-seater bicycle la. In addition, as the spiral portion 18 is formed on the upper portion of the fixing pipe 2. Accordingly, the single-seater bicycle 1 is assembled on the spiral portion 18 by combine screws 19, 19' when assembling as two-seater bicycle la and the two-seater bicycle la is disassembled by separating the combine screws 19, 19' when disassembling as the single-seater bicycle 1. Namely, the two-seater bicycle la is disassembled by separating the rotating pipe 8 connected and disposed to the rotating body 16 of the connecting plate 13 of the body 10a of the rear wheel 5a. In addition, the ring-shaped ball bearing 20, 20' is inserted in the outside of the upper and lower portion of the fixing pipe (2), the rotating pipe 8 is inserted thereon, and a cap 21 is inserted and assembled on the upper end of the fixing pipe 2.
Industrial Applicability
Like the above, the present invention the rotating pipe 8 of the body 10a of the rear wheel 5a is inserted and assembled outside together with the ring-shaped ball bearings 20, 20' from the fixing pipe 2 of the body 10 of the single-seater bicycle 1. At the same time, the combine screws 19, 19' and the cap 21 are inserted and assembled on the spiral portion 18 of the fixing pipe 2. Accordingly, as the present invention has the structure like the above, it has an advantage that the single-seater bicycle 1 can be easily changed into the two-seater bicycle la. In addition, a second driver for using the saddle and handle 3a 4a disposed on the body 10a of the rear wheel 5a when using as the two-seater bicycle la can respectively rotate the wheel by using the pedal 8a for moving the chain 7a in order to easily drive. Particularly, the present invention the body 10a of the rear wheel 5a the rotating body 16 disposed by the bearing axis 15 on the vertical hem portion of the connecting plate 13, can be freely rotated toward the upper and lower portion centering the bearing axis 15. In addition, the rotating pipe 8 inserted on the fixing pipe 2 fixed on the body 10 of the single-seater bicycle 1 can be freely rotated by the ring-shaped ball bearing 17, 17'. Accordingly, the two-seater bicycle la can be safely driven when driving the bumpy road or the road curved with 90° .
In addition, the present invention has an advantage that can easily be disassembled from the state of the two-seater bicycle la to the state of the single-seater bicycle 1, and assembled from the state of the single-seater bicycle 1 to the state of the two- seater bicycle la.
