[0018] At this time, the rotating two-stage bicycle rack (100) of the present invention can be installed at set intervals in a parallel state to allow a large number of bicycles (1) to be mounted in the longitudinal direction.

[0019] The fixed support (110) rests on the ground as shown in FIG. 1 and supports both the front and rear wheels (2a, 2b) of the bicycle (1) It is formed in cross-section.

[0020] And the fixed support (110) is fixed laterally to a support (112) located at the front end and is formed to have a length longer than that of a standard bicycle (1).

[0021] Furthermore, the fixed support (110) has a detachment prevention part (114) formed at the front to prevent the front wheel (2a) from detaching.

[0022] As shown in FIGS. 1 to 4, the fixing member (120) is fixed horizontally to the upper side of the support (112) so that the movable support (130) is seated on it. It is formed in cross-section.

[0023] As shown in FIGS. 1 to 4, the movable support (130) slides on a fixed support (120) supported on the upper side of the fixed support (110) and supports both the front and rear wheels (2a, 2b) of the bicycle (1). It is formed in cross-section.

[0024] And the movable base (130) has rotation guide projections (132) formed protruding from both front sides and is coupled to rotation guide holes (142) formed on both sides of the rotation guide (140).

[0025] Meanwhile, although not shown in the drawing, the movable support (130) may be equipped with rollers (not shown) so that it can slide smoothly along the fixed support (120) on both sides or the bottom surface.

[0026] In addition, the movable base (130) is formed to have a length longer than that of a standard bicycle (1).

[0027] Furthermore, the movable support (130) has a detachment prevention part (134) formed at the front to prevent the front wheel (2a) from detaching.

[0028] The rotation guide (140) is provided at the tip of the movable support (130) as shown in FIGS. 1 to 4, and guides the movable support (130) to be inclined toward the ground or rotated back to its original horizontal position while pulled out from the fixed support (120).

[0029] To this end, the rotation guide (140) has an arc-shaped rotation guide hole (142) formed on each side so that the rotation guide projection (132) of the movable support (130) can be positioned inside, and a buffer (144) to which a shock absorber or the like is applied is installed at the tip so that the movable support (130) can be smoothly rotated in the up and down directions.

[0037] At this time, the first body part (152) is injection molded from a material such as ABS (Acrylonitrile Butadiene Styrene), but is not limited thereto and can be molded from various synthetic resin materials.

[0038] Furthermore, the first body part (152) can be manufactured in various colors.

[0039] And the first gripping rod (1520) is formed to be longer than the length of the first wheel support projection (1522), so that the gripping surface area is widened.

[0040] Additionally, the first wheel support projection (1522) is formed to be longer than half the width of the rear wheel (2b) of the bicycle (1), thereby preventing movement of the mounted rear wheel (2b).

[0041] As shown in FIGS. 5 to 7, the second body part (154) is provided with a symmetrical structure with respect to the first body part (152), and is coupled to the other side of the rear end of the movable base (14). A second gripping rod (1540) is formed on one side of the inner surface, a second wheel support projection (1542) is formed on the other side of the inner surface, and a plurality of coupling holes are formed at the bottom so as to be fastened with a piece (1564) to a fastening hole (136) formed at the rear end of the movable base (14).

[0042] At this time, the second body part (154) is injection molded from ABS material or the like, but is not limited thereto and can be molded from various synthetic resin materials.

[0043] Furthermore, the second body part (154) can be manufactured in various colors.

[0044] And the second gripping rod (1540) is formed to be longer than the length of the second wheel support projection (1542), so that the gripping area is widened.

[0045] Additionally, the second wheel support projection (1542) is formed to be longer than half the width of the rear wheel (2b) of the bicycle (1), thereby preventing movement of the mounted rear wheel (2b).

[0046] As shown in FIGS. 5 to 7, the fastening part (156) consists of a bolt (1560) and a nut (1562) that fix the first and second gripping rods (1520, 1540) and the first and second wheel support protrusions (1522, 1542) of the first and second body parts (152, 154) to each other, and a piece (1564) that fastens the lower end of the first and second body parts (152, 154) to a fastening hole (136) formed at the rear end of the movable base (130).

[0047] Meanwhile, referring to FIG. 8, the first and second wheel support protrusions (1522, 1542) can be positioned in the first and second body parts (152, 154) so ​​that even if the diameter of the rear wheel (2b) of the bicycle (1) is different, the position in contact with the rear wheel (2b) can be made the same.

[0048] To this end, slit holes (156a) are formed in an inclined direction on opposite surfaces of the first and second body parts (152, 154) such that the first and second wheel support protrusions (1522, 1542) are positioned thereon, and a position limiting part (158) is provided for each slit hole (156a) so that the position of the first and second wheel support protrusions (1522, 1542) is temporarily fixed by the position limiting part (158).

[0049] The position limiting part (158) forms a groove (G) at set intervals on the opposite side of the slit hole (156a) with a spacing corresponding to the diameters of the first and second wheel support protrusions (1522, 1542), and each groove (G) is provided with an opening (158a) that moves in and out by means of an elastic body (158b).

[0050] The protruding and retracting opening (158a) has inclined surfaces formed on both sides of the outer end, so that it moves backward regardless of the direction of movement when passing the first and second wheel support protrusions (1522, 1542) to compress the elastic body (158b), and after passing the first and second wheel support protrusions (1522, 1542), it moves forward by the elastic force of the elastic body (158b).

[0051] Meanwhile, the first and second wheel support protrusions (1522, 1542) have a first enlargement protrusion (1522a, 1542a) formed along the outer edge of the first and second body parts (152, 154) and are inserted from both sides of the slit hole (156a) formed on the opposite side of the first and second body parts (152, 154) and then fastened with a bolt (1560) and a nut (1562). The outer diameter of the first enlargement protrusion (1522a, 1542a) is larger than the inner diameter of the slit hole (156a) and is not separated from the slit hole (156a).

[0052] In addition, the first and second wheel support protrusions (1522, 1542) can be positioned by being coupled to one of the multiple holes (126b) formed on the opposing surfaces of the first and second body parts (110, 120).

[0053] The first and second wheel support protrusions (1522, 1542) have a first enlargement protrusion (1522a, 1524a) formed along the outer edge of the first and second body parts (152, 154) and are inserted from both sides of a hole (156b) formed on the opposite side of the first and second body parts (152, 154) and then fastened with a bolt (1560) and a nut (1562). The outer diameter of the first enlargement protrusion (1522a, 1524a) is larger than the inner diameter of the hole (156b) and is not separated from the hole (156b).

[0054] As such, the process of storing a bicycle (1) in two upper and lower tiers using the rotating two-tier bicycle storage rack (100) according to the present invention is described as follows.

[0055] First, in order to mount the bicycle (1) on the lower side of the rotating two-stage bicycle rack (100), the front and rear wheels (2a, 2b) of the bicycle (1) are placed on a fixed support (110) located on the ground.

[0056] Next, in order to mount the bicycle (1) on the upper side of the rotating two-stage bicycle rack (100), when the user grabs the first and second gripping rods (1520, 1540) of the handle (150) and pulls them backward, the movable support (130) slides out of the fixed stand (120).

[0057] At this time, the movable support (130) is rotatably installed on the upper side of the rotational interior (140) and the rod that moves back and forth is rotatably installed at the front end of the movable support (130) so as to maintain a horizontal state.

[0058] Furthermore, the handle (150) is positioned so that the adjacent ends of the first and second gripping rods (1520, 1540) and the first and second wheel support projections (1522, 1542) of the symmetrically formed first and second body parts (152, 154) come into contact with each other, and then the first and second gripping rods (1520, 1540) and the first and second wheel support projections (1522, 1542) are fastened and fixed using a bolt (1560) and a nut (1562), and then the lower end of the first and second body parts (152, 154) is fastened to the fastening hole (136) formed at the rear end of the movable base (130) using a piece (1564).

[0059] In this way, the user can lift or lower the movable base (14) by holding the first and second gripping rods (1520, 1540) of the handle (150), which are made of ABS material or the like, with their hands, and in this process, when the bicycle (1) is mounted on the movable base (130), the rear wheel (2b) is firmly seated on the inner surfaces of both sides of the movable base (130) and the first and second wheel support protrusions (1522, 1542).

[0060] Next, when the user grasps the first and second gripping rods (1520, 1540) of the handle (150) and pulls downward, the rotation guide projections (132) formed on both front sides of the movable base (130) move along the rotation guide holes (142) of the rotation guide (140), causing the movable base (130) to rotate from a horizontal state to an inclined state.

[0061] Next, in order to position the bicycle (1) on the rotated movable base (130), the rear wheel (2b) of the bicycle (1) is placed so that it contacts the first and second wheel support protrusions (1522, 1542), and then the first and second gripping rods (1520, 1540) are grasped and lifted upward. After that, when the movable base (130) is pushed forward, the movable base (130) is drawn into the fixed base (120) and maintains the mounted state.

[0062] The configurations included in the various embodiments described above may also be implemented in various other possible modified combinations not exemplarily described above, provided that such combinations are not clearly excluded from one another in terms of implementation.
