Please refer to FIGS. 1 to 5. The multifunctional bicycle stand of the present invention is mainly used to hang or park a bicycle 10 for exhibition, and has two main structures. The first main structure of the multifunctional bicycle stand includes a main pipe 1, a hanging assembly 2, a support stand 3 and at least one positioning rod group 4. The main pipe 1 is in a round tube shape, and the hanging assembly 2 is mounted on a top of the main pipe 1 and configured to hang a front wheel 101 of a bicycle 10. The hanging assembly 2 includes a hanger rod 21 continuously bent in multiple directions, a lateral rod 22 in the same shape as the hanger rod 21, a connecting holder 23 in an arc plate shape, and a locking member 24. The connecting holder 23 has an arc-concave end abutted with an outer periphery of a top of the main pipe 1, and other end extended, perpendicularly to the main pipe 1, to form a horizontal rod 25. The locking member 24 is inserted through the main pipe 1 and tightly locked in the connecting holder 23; in this embodiment, the main pipe 1 has multiple holes formed thereon, and the locking member 24 can be inserted into and locked with the multiple holes. An end of the hanger rod 21 and an end of the lateral rod 22 are connected to the horizontal rod 25, and the hanger rod 21 and the lateral rod 22 are arranged in parallel with each other and in interval. In use, the hanger rod 21 and the lateral rod 22 both can be inserted through a front wheel 101 of the bicycle 10 to firmly mount the bicycle 10. In this embodiment, the multifunctional bicycle stand is implemented with two hanging assemblies 2 for hanging two bicycles 10 on the main pipe 1 for exhibition and mounting. The support stand 3 is disposed on a bottom end of the main pipe 1 and configured to support the main pipe 1, and the support stand 3 includes a plurality of support rods 31 (as shown in figures, the support stand 3 includes four support rods 31), and two adjacent support rods 31 can form an included angle area 32 therebetween. The at least one positioning rod group 4 has two ends fixed on any two adjacent support rods 31, respectively, and across the corresponding included angle area 32, so that the at least one positioning rod group 4 can form a restraining channel 41. When the bicycle 10 is parked on the multifunctional bicycle stand 10, the bicycle can be hung on the hanging assembly 2 to form a standing mode; alternatively, a front wheel 101 or a rear wheel 102 of the bicycle 10 can be directly accommodated in the restraining channel 41 to firmly park the bicycle 10 in a non-standing mode.

Generally, sizes and heights of exhibition halls or stores for the bicycles 10 are not the same; in order to maintain consumers' viewing experiences in purchasing the bicycle 10, with configuration of the multifunctional bicycle stand of the present invention, the bicycle 10 can be hung in the standing mode when the height of the exhibition hall or store is sufficient, and the user only needs to hang the front wheel 101 of the bicycle 10 on the hanging assembly 2 and insert the hanger rod 21 and the lateral rod 22 through a rim of the front wheel 101, so as to complete the hanging placement of the bicycle 10; in the other hand, when the height of the exhibition hall or store is not enough for the bicycle 10 to be hung, the user only needs to park the bicycle 10 in the non-standing mode in which the front wheel 101 or the rear wheel 102 is directly accommodated in the restraining channel 41, so as to complete non-hanging placement of the bicycle 10. Therefore, the multifunctional bicycle stand of the present invention can be applied to the places with different heights, and enable women and children with less strength to directly mount the bicycle in the restraining channel 41 of the at least one positioning rod group 4 to prevent difficulty in hanging the bicycle 10 due to insufficient strength. Furthermore, multiple bicycles 10 can be hung or placed horizontally together on the multifunctional bicycle stand of the present invention.

More details of the first main structure of the present invention will be described in following paragraphs. The at least one positioning rod group 4 includes two arched pipes 42, and each arched pipe 42 is in an inverted-U shape, and the two ends of each arched pipe 42 are fixed on any two adjacent support rods 31, and the two arched pipes 42 are arranged in interval, and the interval formed between the two arched pipes 42 is defined as the restraining channel 41 mentioned above. A user can place the front wheel 101 or the rear wheel 102 of the bicycle 10 directly into the restraining channel 41 to complete the horizontal mounting of the bicycle 10, as shown in FIG. 5. Furthermore, in order to make the main pipe 1 to stably support the hanging placement of the bicycle 10, the support stand 3 can include a mounting pipe 33, an end of each of the support rods 31 is connected to an outer side surface of the mounting pipe 33, every two adjacent support rods 31 can form an included angle area 32 therebetween. The mounting pipe 33 has an insertion slot 331 recessed on a top surface thereof and toward the bottom surface thereof, and the main pipe 1 is inserted into the insertion slot 331. The configuration of the mounting pipe 33 and the support rod 31 can be used to support the main pipe 1 to stand, as shown in FIG. 2.

It is also worth mentioning that in order to improve the stability of the bicycle 10 hung on the multifunctional bicycle stand of the present invention to reduce large side-to-side swing, the multifunctional bicycle stand of the present invention can further include at least one bent pipe 5 mounted on the main pipe 1 disposed between the hanging assembly 2 and the support stand 3. The at least one bent pipe 5 can include a curved plate 51 and a bow-shaped pipe 52, the curved plate 51 has the same structure as that of the connecting holder 23, and the bow-shaped pipe 52 is M-shaped and has an end connected to a side of the curved plate 51. A curved recessed part of the curved plate 51 is abutted with the main pipe 1, and the bow-shaped pipe 52 is continuously bent to form at least one curved part 521. When a user parks the bicycle 10 in a hanging mode, the front wheel 101 of the bicycle 10 is hung on the hanger rod 21 and the lateral rod 22 of the hanging assembly 2, the rear wheel 102 is accommodated in the at least one curved part 521 and abutted with the bow-shaped pipe 52, and a screw 53 can be inserted through the main pipe 1 and locked with the curved plate 51. Therefore, the hung bicycle 10 can be prevented from being affected by an external force, so as to reduce swing magnitude of the hung bicycle 10, as shown in FIG. 3.

The difference between the first and second main structures of the present invention is the configuration of the at least one positioning rod group 4. The at least one positioning rod group 4 of the first structure is formed by arranging the two arched pipes 42 in interval; in the second structure of the present invention, the at least one positioning rod group 4 is separated into at least one fixed rod 43 and at least one movable and extendable rod 44, and two ends of the at least one fixed rod 43 is fixed on any two adjacent support rods 31, similar to the two arched pipes 42. The at least one movable and extendable rod 44 is slidably disposed on any two adjacent support rods 31 which are fixed with the at least one corresponding fixed rod 43, and the at least one movable and extendable rod 44 is disposed between the at least one fixed rod 43 and the main pipe 1, so that the at least one movable and extendable rod 44 is slidable to move close to or away from the main pipe 1, and a restraining channel 41 can be formed between the at least one fixed rod 43 and the at least one movable and extendable rod 44 and in communication with the included angle area 32 corresponding thereto. Therefore, the at least one movable and extendable rod 44 can be slid to change a width of the restraining channel 41, to adaptively place different wheel with different wheel diameter, as shown in FIGS. 6 to 11.

The second structure of the present invention can be implemented by two embodiments. Please refer to FIGS. 7 to 9, which show the first embodiment of the second structure. In the first embodiment of the second structure, at least one movable and extendable rod 44 includes a plurality of slidable mounting plates 441 disposed on two ends thereof, respectively, and each of the plurality of slidable mounting plates 441 is in an arc shape and abutted with the support rod 31 corresponding thereto, and the area of each slidable mounting plate 441 attached to the support rod 31 should exceed more than half of the outer surface of the support rod 31. A plurality of bolts 45 corresponding in number to the plurality of slidable mounting plates 441 are inserted into and locked with the plurality of slidable mounting plates 441, respectively, so as to tightly lock and abut against the outer surfaces of the support rods 31. When each bolt 45 is locked and abutted with the outer surface of the support rod 31, the slidable mounting plate 441 is slightly deformed to engage with the support rod 31; the bolts 45 can be firmly locked to fasten the at least one movable and extendable rod 44 after the at least one movable and extendable rod 44 is moved; in the other hand, after the bolts 45 are loosened relative to the slidable mounting plates 441 to release the slidable mounting plates 441 from abutting against the outer surface of the support rods 31, the at least one movable and extendable rod 44 is slidable to move close to or away from the main pipe 1. Please refer to FIGS. 10 to 13, which show the second embodiment of the second structure. Besides the manner of sliding the at least one movable and extendable rod 44, the support rods 31 of the second embodiment can have sliding slots 311 formed and recessed on the corresponding opposite inner sides thereof, respectively, and each sliding slot 311 can be in a dovetail shape, and the at least one movable and extendable rod 44 can have two locking holes 442 cut through two ends thereof and corresponding in position to openings of the sliding slots 311 of the support rods 31, respectively. Fastening blocks 46 are slidably disposed in the sliding slots 311 and engaged with the openings of the sliding slots 311, respectively, and each fastening block 46 has a screw hole 461 formed correspondingly in position to the corresponding one of the locking holes 442, and screw members 6 can be inserted through the locking hole 442 and locked with the screw holes 461 of the fastening blocks 46, respectively; after the screw member 6 are tightly screwed with the fastening blocks 46, the fastening blocks 46 and the screw members 6 are tightly locked with the two ends of the at least one movable and extendable rod 44 and the support rods 31, so as to fasten the at least one movable and extendable rod 44 after the at least one movable and extendable rod 44 is adjusted. In order to adjust the at least one movable and extendable rod 44, the user just needs to loosen the screw members 6 relative to the fastening blocks 46 to release the screw members 6 and the fastening blocks 46 from tightly packing the at least one movable and extendable rod 44 and the support rods 31, and then the at least one movable and extendable rod 44 can be adjusted to slide along the direction of the sliding slot 311 to move close to and away from the main pipe 1, so as to make the restrain channel fit with the wheel frame width of the front wheel 101 or the rear wheel 102 of the bicycle 10 to firmly mount the bicycle 10.

According to the above description, each of the at least one movable and extendable rod 44 and the main pipe 1 is implemented by a telescopic structure, for example, the at least one movable and extendable rod 44 can include a male pipe member 443 and a female pipe member 444, and each of the male pipe member 443 and the female pipe member 444 is L-shaped, an end of the male pipe member 443 is inserted into an end of the female pipe member 443, and other ends of the male pipe member 443 and the female pipe member 443 are slidably connected to the support rod 31 corresponding thereto, so that the insert connection between the male pipe member 443 and the female pipe member 443 is slidably adjustable in cooperation with movement of the at least one movable and extendable rod 44, as shown in FIGS. 7 and 9. A part of the main pipe 1 includes an upper pipe member 11 and a lower pipe member 12, the upper pipe member 11 is inserted into the lower pipe member 12, and the upper pipe member 1I is extendably adjustable relative to the lower pipe member 12; with the above-mentioned telescopic adjustment functions of the at least one movable and extendable rod 44 and the main pipe 1, the present invention can be applied to the places with different heights smoothly, and the bicycle 10 can be mounted stably and not easily shaken or swung in the standing mode or the non-standing mode, as shown in FIGS. 7, 11 and 12.

In summary, the multifunctional bicycle stand of the present invention can provide the user to exhibit and mount the bicycle 10 in places with different heights in the hanging mode or non-hanging mode; when the height of the exhibition place is sufficient, the front wheel 101 of the bicycle 10 can be hung on the hanging assembly 2 to prevent the bicycle 10 from being easily swung by external force; in the other hand, when the height of the exhibition place is not enough for hanging the bicycle 10, the user just needs to shrink the main pipe 1 to the shortest length for parking the bicycle 10. Therefore, the multifunctional bicycle stand of the present invention can provide the user with more diversified exhibition manner and mounting manner. Furthermore, the multifunctional bicycle stand of the present invention can also be used in houses or public places to park and mount the bicycle 10; for example, when parking the bicycle 10, a child who is not tall, or a woman with petite body and less strength may be unable to mount the bicycle 10 in the hanging mode; therefore, the multifunctional bicycle stand of the present invention includes the at least one positioning rod group 4 or combination of the at least one fixed rod 43 and the at least one movable and extendable rod 44 on the support stand 3, so that children and women can directly accommodate the front wheel 101 or the rear wheel 102 of the bicycle 10 in the restraining channel 41 and then adjust the at least one movable and extendable rod 44 to move close to the at least one fixed rod 43, thereby restraining the front wheel 101 or the rear wheel 102 of the bicycle 10 by a smaller space, to stably park and mount the bicycle 10.
