Definitions

• This invention relates to a bicycle, and in particular, to a bicycle which is able to overcome obstacles on the ground like a sidewalk.
• This invention is about a bicycle. If we see it more in detail, this is with regards to a bicycle that has such a secondary wheel that is additionally equipped at each front and rear wheel of bicycle and pass over easily such an obstacle as sidewalk. This secondary wheel is to move the main wheel up. Generally, bicycles that equip such a multi-stepped transmission had been develop and have been using widely up to now to climb up a hill casi ly.
• FIG. 1 is to show the side-view of one example of the present invention.
• FIG. 2 is to show the side-view of another example of the present invention.
• FIG. 3 is to show the side-view of another example of the present invention.
• FIG. 4 is to show the side-view of another example of the present invention.
• FIG. 5 is to show the side-view of another example of the present invention on an uneven ground.
• FIG. 6 is to show the side-view of another example of the present invention.
• FIG. 7 is to show the side-view of another example of the present invention.
• FIG. 8 is to show the top-view of another example of the present invention.
• this invention can be achieved by a bicycle that has a smaller diameter of the secondary wheel than a main wheel and this secondary wheel supported by the first frame and second frame is located at upper part of the front and the rear side of a wheel.
• this invention includes that a secondary wheel is arranged in 2 rows.
• this invention includes that a secondary wheel is installed at the frame and also can be detachable out of the frame.
• this invention includes that a support frame is installed at a main frame and it can control the angle of a secondary whee1.
• this invention includes that the outer diameter of a wheel is same as the secondary wheels.
• this invention includes that a secondary wheel having three rolling wheels that are positioned evenly around circle is installed at the front upper part of the wheel and can be rotated.
• this invention includes that this secondary wheel having the rolling wheels are arranged in 2 rows.
• this invention includes that a secondary wheel having the rolling movement part like a roller blade shape is installed at the front upper portion of a wheel.
• this invention includes rolling movement parts are arranged in 2 rows.
• this invention includes the front part of a rolling X movement part in a roller blade shape inclines upside.
• this invention includes an unlimited circular wheel is installed at the front upper portion of a wheel.
• this invention includes an unlimited circular wheel is arranged in 2 rows.
• this invention includes the front part of an unlimited circular wheel inclines upper.
• this invention includes that a secondary wheel consists of several wheels that have small diameter and are positioned evenly around the circle.
• this invention includes that the wheels are arranged in 2 rows.
• this invention includes that a secondarv wheel at the front upper part of a wheel consists of several rolling wheels that are positioned evenly around the arc.
• this invention includes that the wheels of rolling part are arranged in 2 rows and an unlimited circular wheel composes the upper i nc 1 ined .
• FIG. 1 is to show the side-view of one example of i hc present invention.
• a frame (12) with a handle (10) at the upper side is equipped, and a saddle (14) at the middle upper side of the frame which can be seated on is installed.
• the front wheel (16) and the rear wheel (18) at both side of frame(12) are installed to be rotated, and a pedal at the middle lower section of this frame(12) is installed to rotate the wheels (1(5), (18).
• a diameter of the secondary wheel (22) which is smaller than a diameter of the wheel (16), (18) is installed, and this secondary wheel (22) is located at the front and the rear side of the wheel (16), (18) by the first frame(24) and second frame(26).
• the secondary wheel (22) is desirable that the wheel of rolling part is arranged in 2 rows for contacting on the ground and the secondary wheel (22) is installed at the frame (12) can be detachable.
• a support frame (24), (26) is installed at the frame (12) to control the angle of the secondary wheel.
• the secondary wheels at the front upper portions of the wheels (16), (18) are located at the upper side of an obstacle by the support frames (24), (26).
• the front wheel of a bicycle (16) contacts with the side of an obstacle and at the same time a secondary wheel (22) contacts with the upper side of an obstacle. At this moment, as a secondary wheel (22) contacts with the upper side of the obstacle, the front part of bicycle is lifted up a little.
• the secondary wheels (22) installed at the front parts of the wheels (1(5), (18) can be transfer on the obstacle and so a bicycle passes over easily such an obstacle as a sidewa1k .
• FIG. 2 is to show the side-view of another example of the present invention.
• outer diameters of the wheels (16), (18) are same with those of the secondary wheels (22), we can get the same effectiveness like the upper statement.
• outer diameter of secondary wheel (22) isn't limited at Fig. 2. And it can be modulated optionally.
• FIG. 3 is to show the side-view of another example of the present invention.
• FIG. 4 is to show the side-view of another example of the present invention.
• the rolling part (28) is arranged in 2 rows and the contact area is maximized, then, though the rolling part contacts with an obstacle, we can protect to slip by the impact.
• FIG. 5 is to show the side-view of another example of the 1 present invention.
• the unlimited circular wheel (30) is arranged in 2 rows and the contact area is maximized, then, though the unlimited circular wheel (30) contacts with an obstacle, we can protect to slip by the impact.
• FIG. 6 is to show the side-view of another example of the present invention.
• a wheel is composed of a small diameter and it is arranged on a circular line with same step at a central point, we can get the same effectiveness like the upper statement.
• FIG. 7 is to show the side-view of another example of the present invention.
• the rolling parts (34) in which several rolling wheels (32) are positioned evenly around the arc are installed at the front upper parts of the wheels (16), (18). And they (34) can be rotated at a cold point on a circular line. Then we can get the same effectiveness like the upper statement.
• FIG. 8 is to show the top-view of another example of the present invention.
• the wheel of rolling part (34) consists of 2 rows; the distance of this wheel (32) axle is composed shortly from the front to the rear.
• wheels (32) of the rolling part (34) are arranged in 2 rows and the contact area is maximized.
