Figure 4 is a cross-sectional view of a portion of the frame of the unicycle shown in Figure 1. , FIG. 5 shows a part of the frame of the unicycle of the present invention shown in FIG. a perspective view of a clamp used to connect a short pipe; FIG. 6 is a perspective view of a unicycle according to a second embodiment of the present invention.

nighttime of invention Cycle 10 is illustrated.

Wheel 12 is provided with an axle 16 and a pneumatic tire 18 of conventional type.

A pair of pedals 20 are connected to respective ends of the axle 16.

A bearing assembly 22 is mounted on the axle 16 adjacent each pedal 20. bearing Assembly 22 is illustrated in FIG. This bearing assembly 22 accommodates the axle 16. It has a through hole. This bearing assembly 22 allows the axle 16 to rotate. However, it does not rotate itself. An upright portion 24 extends from each bearing assembly 22. short A tube 26 fits over each upright section 24 and is attached to it by screws 28. It will be done.

The frame 14 is generally tubular in shape and has a pair of straight lines on each side of the wheels 12. It has shaped portions 30a and 30b. Portion 32 extends upwardly and forwardly from portion 30a. and extends toward the longitudinal centerline of the unicycle 10. This is the first This is illustrated in Figure 4. Next, the portion 34 is aligned with the longitudinal centerline of the unicycle 10. It extends linearly along and engages the portion 32 connected to the underside of the portion 34 . next , portion 34 extends upwardly to a handleper attachment 36. plate 3 8 connects portions 30a130b. Sheet 40 is the longitudinal side of Unicycle 10 It is attached to a portion 34 of frame 14 that extends along the central axis.

Handlebar attachment 36 is shown separately in FIG. handlebar - the attachment 36 has a first portion 42 connected to the portion 34 of the frame 14; , and a second portion 44.

1st. The portion 42 is formed with a transversely oriented semicircular groove 46. ing. The second portion 44 of the handlebar attachment 36 is generally plate-shaped. It has a semi-circular groove 48 oriented transversely. .

The handlebar attachment 36 attaches the handlebar 50 to the unicycle 10. keep it in place.

The portion 52 of the handlebar 50 is connected to the first and second portions of the handlebar attachment 36. is housed within grooves 46.48 of portions 42.44 of. The second portion 44 is connected to the first and second portions. It is secured to the first part 42 by a bolt 54 passing through an engagement hole 56 in the second part 42,44. It will be worn. A nut (not shown) is then secured onto the free end of the bolt 54 and the bolt 54 can be secured within hole 56.

The handle par 50 is rigidly held within the handle par attachment 36 and is cannot rotate relative to the arm 10.70.

A handlebar 50 is provided at each end thereof -40:I/'7 F#5 8t-equipped. The handle 58 is relative to the longitudinal centerline of the Unicycle 10. They are spaced apart so that they cross each other. Handle par 50 is even more cross par 60 Provides stiffness and rigidity.

The putting 62 (illustrated with imaginary lines) is a cross par 60 in front of the seat 40, around the handlebar attachment 36 and the portion 34 of the frame 14. I can do that. Straight portions 30a, 30b fit onto respective short tubes 26. straight line The ends of the shaped portions 30a, 30b have longitudinal edges best shown in FIGS. 3 and 5. A cutout slot 63 is formed that extends in the direction.

Clamps 64 fit around the ends of each section 30a, 30b. This clamp 64 is shown in FIG. The clamp 64 has a pair of outwardly bent ends. is provided to form a protrusion 66.

The protrusion 66 has a hole 68 extending therethrough. A bolt (not shown) passes through hole 68; A nut (not shown) is tightened onto the end of this bolt. This results in two The projections 66 are brought close together to close the clamp 64 around the portions 30a, 30b. let The slot 63 allows the ends of the sections 30a, 30b to wrap around the short tube 26. tightly occluded so that portions 30a, 30b are in place on their respective short tubes 26. Fixed. Therefore, the positions of the portions 30a and 30b on the short pipe 26 are It is possible to make adjustments using the tap 64.

In FIG. 6, a unicycle 70 according to a second embodiment of the invention is illustrated. Ru. This Unicycle 70 is similar to the Unicycle 10 of the first embodiment; Therefore, in the drawings, similar parts in the two embodiments use similar reference numerals. Display using.

The Unicycle 70 of the second embodiment is different from the parts of the Unicycle 10 of the first embodiment. Special table 103-501108 (3) do. However, explanations of other parts of Unicycle 70 are also included in the Unicycle 10 section. It will be understood that the same applies to goods.

The unicycle 70 includes an axle 12, a handlebar 50, and a frame 72. It is growing.

The frame 72 has a substantially tubular shape, extends rearward, and connects at an rUJ-shaped bent portion. It has continuous portions 30a, 30b.

Portion 74 of frame 72 connects from the rUJ-shaped bend to the handlebar attachment. It has grown to 36.

The linear portion 76 extends upward from each portion 3Qa, 30b. Straight section 7 6 is connected to the lower side of the front end of portion 74.

The handle parr 50 is provided with a cross parr 78 having a bent portion (clearly shown). In order to make it more accurate, the batting was omitted from Cross Par 78).

Crosspar 60 used in Unicycle 10 is also used in Unicycle 70. I can do it. Similarly, the cross spar 78 used in the Unicycle 70 is It can also be used for Nicycle 10.

On Unicycle 10.70, the rider must use the handlebar attachment 36. A portion of the handlebar 50 can be adjusted via the handlebar 50. For this reason, the handle The position of the par 50 can be adjusted forward or backward, and the handle 58 can be adjusted to the most convenient position for the rider. It is possible to make it appear in a certain position.

The position of portions 3Qa, 30b on the short pipe 26 is determined by first loosening the clamp 64. It can be changed depending on.

This releases portions 30a, 30b from engagement with short tube 26. Next, short Tube 26 may be pushed further into sections 30a, 30b or further from these sections. It can be made to retreat. Once the part is in the desired position, then clamp 64 can be loosened again. In this way, the user can The height of the frame 14 can be adjusted. This causes the pedal 20 to move upward. The height of the seat 40 can be effectively adjusted to suit the user. come. Additionally, the adjustable height also allows for larger heights if desired. allows the use of wheels of smaller or smaller diameter. The unicycle of the present invention is The user, i.e. the rider, balances and steers the Unicycle 10.70. Allows direction to be controlled more easily. This is the handle par 50 and ha According to Handle 58. The handle 58 of Unicycle 10.70 of the present invention is Unicycle 10.70. spaced apart transversely to the longitudinal centerline of the wheel 10.70. this This allows the rider to use the conventional uni-sight bike, which does not use a handlebar for the rider at all. Balancing and steering can be controlled more easily than in the case of a cruiser. Become.

In use, the rider sits on the seat 40 and pedals 20 with his/her own hands in the conventional manner. The Unicycle 10.70 is propelled by rotating. Rider is Han Grasp the handle 58 of the Dorpar 50 and place it on the Unicycle 10.70. control the balance. Furthermore, by grasping the handle 58, the rider can to steer the unicycle by pulling one handle 58 in the proper direction. I can also do it.

The handlebar 50 is attached to the handlebar attachment 36 (this is the frame 14. 74), the handle 58 can be operated with a click. Transmitted to frame 14.74 and wheel 12, balance of Unicycle 10.70 and take control.
