FIELD OF INVENTION
The present invention relates to a vehicle-carried rack for bicycles.
BACKGROUND OF INVENTION
Referring to FIG. 11, a conventional rack includes a first frame 100 and a second frame 200. The first frame 100 includes a U-shaped element 110 and two rectilinear elements 120. The U-shaped element 110 includes two ends each for receiving an end of one rectilinear element 120. A spring-biased detent 300 is provided in order to lock each rectilinear element 120 to one end of the U-shaped element 110. The second frame 200 includes two U-shaped elements 210 and 220. The U-shaped element 210 includes two ends each for receiving one end of the rectilinear elements 220. A spring-biased detent 400 is provided in order to lock each end of the U-shaped element 220 to one end of the U-shaped element 210. Each end of the U-shaped element 220 defines an aperture 224. Each end of the U-shaped element 210 defines four apertures 213, 217, 218 and 219. The spring-biased detent 400 can be inserted in the aperture 213, 217, 218 or 219 through the aperture 224. Thus, the length of the second frame 200 is adjustable. To connect the first frame 100 with the second frame 200, each rectilinear element 120 is connected with one end of the U-shaped element 220. In use, referring to FIG. 12, the U-shaped element 110 is put on the trunk or boot of a vehicle. The U-shaped element 210 is put on the rear bumper of the vehicle. Two belts 500 are wound around the trunk or boot. Each belt 500 includes an end tied to an end of the U-shaped element 110 and another end tied to an end of the U-shaped element 210. The upper tube of a bicycle can be supported on the rectilinear elements 120. However, the bicycle tends to slide on the rectilinear elements 120.
The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art.
SUMMARY OF INVENTION
According to the present invention, a rack is provided for holding at least one bicycle in position. The rack comprising a base, two beams pivotally connected with the base, at least one supporting device attached to each of the beams in order to support one wheel of the bicycle, a post pivotally connected with the base, a hooking device attached to the post in order to hook a portion of the bicycle. The primary advantage of the rack is the ability of holding the bicycle in position.

DETAILED DESCRIPTION OF EMBODIMENTS
Referring to FIG. 1, a bicycle 14 is carried on a vehicle 10 by means of a rack 20 according to the preferred embodiment of the present invention.
Referring to FIGS. 2, the rack 20 is detached from the vehicle 10. A socket 12 is secured to the vehicle 10. An insert 30 of the rack 20 can be inserted in the socket 12. A pin 13 can be driven in the insert 30 through the socket 12. Therefore, the rack 20 can be attached to the vehicle 10 as shown in FIG. 1.
Referring to FIG. 3, the rack 20 includes a collar 40 that can be put around the insert 30, a base 50 secured to the collar 40, two beams 70 pivotally connected with the base 50, two supporting devices 73 movably installed on each beam 70, a post 60 pivotally connected with the base 50 and two hooking devices 63 movably installed on the post 60. A wheel 16 (FIG. 2) of the bicycle 14 can be supported on each supporting device 73. The upper tube 15 of the bicycle 14 can be hooked by means of each hooking device 63.
Referring to FIG. 4, the collar 40 includes two wings 41 secured thereto and a nut 42 secured thereto. A screw 43 is engaged with the nut 42. In assembly, the collar 40 is put around the insert 30. The screw 43 is driven in the collar 40. Thus, the insert 30 is abutted by means of the screw 43. Therefore, the collar 40 is secured to the insert 30.
The base 50 includes a bottom 51 and two walls 52 extending from the bottom 51. A plurality of apertures 53 is defined in each wall 52. The bottom 51 is secured to the collar 40 including the wings 41.
A screw 71 is driven in each beam 70 through one aperture 53 of each wall 51. Thus, the beams 70 are pivotally connected with the base 50. Each screw 71 is engaged with a nut 76. A pin 72 can be inserted in each beam 70 through one aperture 53 of each wall 51 so as to keep each beam 70 in a horizontal position or vertical position (FIG. 10).
Each supporting device 73 includes a collar 74 and an oval ring 73 secured to the collar 74. The collar 74 is put movably on one beam 70. The collar 74 can be secured to one beam 70 by means of a screw 77. The oval ring 73 can support one wheel 16 of the bicycle 14.
A screw 61 is driven in the post 60 through one aperture 53 of each wall 51. Thus, the post 60 is pivotally connected with the base 50. The screw 61 is engaged with a nut (not shown). A pin 62 can be inserted in the post 60 through one aperture 53 of each wall 51 so as to keep the post 60 in a horizontal position (FIG. 9) or vertical position.
Each hooking device 63 includes a collar 64 and a hook 65 secured to the collar 64. The collar 64 is put movably on the post 60. The hook 65 can hook the upper tube 15 of the bicycle 14. Now, each collar 64 can be locked in position on the post 60 by means of a locking device 66.
Referring to FIG. 5, two series of teeth 67 are formed on the post 60. A shell 68 is formed on each collar 64. A window 69 is defined in each shell 68. Each locking device 66 includes a detent 78 pivotally put in one shell 68 and a spring 79 for biasing the detent 78 towards the post 60. The detent 78 is formed with teeth 80 for engagement with the teeth 67. A screw 81 is driven in each detent 78 through one shell 68. Thus, each detent 78 is pivotally put in one shell 68. Each screw 81 is engaged with a nut 82.
Referring to FIG. 6, the teeth 80 are engaged with the teeth 67 so that each hooking device 63 is locked in position on the post 60.
Referring to FIG. 7, through the window 69, the detent 78 can be pivoted in order to disengage the teeth 80 from the teeth 67. Thus, each hooking device 63 is allowed to slide on the post 60.
Referring to FIG. 8, each wheel 16 is held by means of one oval ring 75. The upper tube 15 is hooked by means of one hook 65.
The present invention has been described via detailed illustration of some embodiments. Those skilled in the art can derive variations from the embodiments without departing from the scope of the present invention. Therefore, the embodiments shall not limit the scope of the present invention defined in the claims.
