DETAILED DESCRIPTION

(9) With reference to FIGS. 1-8, a bicycle vertical rack 100 according to a preferred embodiment of the present invention is capable of being adjusted to a desired fixed angle, the bicycle vertical rack 100 comprises a base 10, a support post 20, two hanging holders 30, and a fixer 40.

(10) Referring to FIG. 1, the base 10 is mounted on the ground.

(11) As shown in FIG. 1, the support post 20 includes a first connection column 21, a second connection column 22, and a height adjustment unit 23. A bottom of the first connection column 21 is vertically connected with the base 10, and a bottom of the second connection column 22 is fitted with a top of the first connection column 21, such that the support post 20 is erected vertically. The height adjustment unit 23 is fixed between the first connection column 21 and the second connection column 22 so as to adjust a position of the first connection column 21 with respect to a position of the second connection column 22. For example, when the height adjustment unit 23 is released, the second connection column 22 is slidable upward and downward with respect to the first connection column 21 so as to be adjustably moved to a desired height. When the height adjustment unit 23 is forced, the second connection column 22 and the first connection column 21 are not slidable to fix a total height of the first connection column 21 and the second connection column 22.

(12) Referring to FIGS. 1-8, the two hanging units 30 are connected with the first connection column 21 and the second connection column 22 of the support post 20, wherein a respective one hanging unit 30 includes a coupling element 31, a fixing tube 32, a rotary tube 33, a resilient element 34, a defining element 35, a horizontal plate 36, and two hooks 37. The coupling element 31 is connected to an outer wall of the support post 20, and the coupling element 31 has an arcuate sheet 311 and multiple screw bolts 312, wherein the arcuate sheet 311 contacts with the outer wall of the support post 20, the multiple screw bolts 312 are inserted through the arcuate sheet 311 and the support post 20 to lock the arcuate sheet 311 on the outer wall of the support post 20. The fixing tube 32 is hollow and includes a through hole 321 defined thereon, wherein the through hole 321 is threaded, and a rear end of the fixing tube 3 is connected with the arcuate sheet 311 of the coupling element 31 so that the fixing tube 32 is connected with the support post 20 at 90 degrees, i.e., the support post 20 is vertical with respect to the fixing tube 32, and the fixing tube 32 is horizontal with respect to the support post 20. The rotary tube 33 has a rotatable extension 331, a first fitting sleeve 332 fitted on a rear end of the rotatable extension 331, and a second sleeve 333 fitted on a front end of the rotatable extension 331, wherein the rear end of the rotatable extension 331 and the first fitting sleeve 332 are received in the fixing tube 32, the rotatable extension 331 has a movable groove 334 defined thereon, a recess 335 and multiple cutouts 336 which are defined on the movable groove 334, wherein the multiple cutouts 336 are defined parallelly and extend axially, and any two adjacent cutouts 336 are spaced from a predetermined distance, an end of a respective one cutout 336 communicates with the recess 335. The resilient element 34 is a compression spring and is accommodated in the fixing tube 32, wherein a first end of the resilient element 34 abuts against a rear end of the fixing tube, and a second end of the resilient element 34 contacts with the first fitting sleeve 332 of a rear end of the rotary tube 33. The defining element 35 is received in the through hole 321 of the fixing tube 32 and the movable groove 334 of the rotary tube 33. In this embodiment, the defining element 35 is a screw and is received in the movable groove 334 after being screwed with the through orifice 321. An inner wall of a middle section of the horizontal plate 36 is horizontally connected with a front end of the rotary tube 33. The two hooks 37 are connected to an outer wall of the horizontal plate 36 in a predetermined distance.

(13) As illustrated in FIG. 1, the fixer 40 is horizontally connected to the support post 20 to abut against a wall stably. The fixer 40 includes a locking portion 41 formed on a middle section thereof and configured to connect to the outer wall of the second connection column 22 of the support post 20, wherein the fixer 40 is located opposite to the two hanging units 30, and the fixer 40 includes two contact portions 42 formed on two ends thereof to contact with the wall.

(14) In operation, a top tube 91 of the bicycle is mounted on the two hooks 37 of one hanging unit 30. When the top tube 91 is not horizontal, the horizontal plate 36 tilts with a unstable gravity center, and the horizontal plate 36 is forced by a user so that the rotary tube 33 pushed by the resilient element 34 is moved inward (as shown in FIG. 3), hence the defining element 35 is urged by the rotary tube 33 to slide into the movable groove 334 (as illustrated in FIG. 6) from one of the multiple cutouts 336 (as shown in FIG. 4). In the meantime, the horizontal plate 36 is rotated by the user to actuate the rotary tube 33 to revolve until the gravity center of the bicycle is stable. Thereafter, the horizontal plate 36 is released so that the rotary tube 33 is pushed by the resilient element 34 to move outward, and the defining element 35 slides into a corresponding cutout 336 (as shown in FIG. 7), thus stabilizing the gravity center of the bicycle on the top tube 91 (as shown in FIG. 8).

(15) In the above-mentioned embodiments, the horizontal plate 36 is driven by the user to rotate the rotary tube 33 or to move the rotary tube 33 inward. In actual use, the user forces the bicycle to rotate the rotary tube 33 or move the rotary tube 33 inward.

(16) The resilient element is configured to push the rotary tube outward or inward and to move in the multiple cutouts so that the horizontal plate is adjustably moved and positioned horizontally or at any tilted angles based on using requirements, thus fixing the bicycle on the bicycle vertical racks stably.

(17) In another embodiment, at least three hanging units (such as four hanging units) are provided to fix the bicycle.
