Apparatus for minimizing a turning radial of bicycle

摘要

The present invention relates to an apparatus to minimize a turning radius of a bicycle. According to the present invention, the apparatus to minimize a turning radius of a bicycle comprises: an upper frame including a bicycle frame support (11), a thread groove (13) formed on a side surface of the bicycle frame support (11), and a screw formed along the thread groove (13); a post frame (20) connected to a groove of the bottom of the upper frame (10) and including a compressive spring (21) attached to the top of a lower frame (30); and an I-shaped support (40) installed in a lower frame groove (37) formed at a middle part of the lower frame (30). The I-shaped support (40) is connected to a height adjustment member (32) through a first height adjustment member pin (34). A Y-shaped support (42) is connected to the height adjustment member (32) through a second height adjustment member pin (44), and includes a rod frame protrusion part (31) formed on the lower part of the lower frame (30) and a ring frame protrusion part (35). Accordingly, the turning radius of a bicycle is minimized, thereby providing effects of reducing collision probability between a bicycle rider and a pedestrian, quickly changing a direction when turning the bicycle by 180°, and being easily used by people of all ages and both sexes.
