Description:
FIELD OF THE INVENTION 
     The present invention relates to a hanging device that can be foldable and includes a plurality of support rods on which bicycles can be supported. 
     BACKGROUND OF THE INVENTION 
     Conventionally, bicycles are parked outside of the house and usually locked by a variety of locks. Nevertheless, because the bicycles are light in weight, they can be easily taken away by thieves without any difficulty. Therefore, owners often carry their bicycles to their apartments and park the bicycles in rooms or on the patio. The bicycles occupy a lot of space which is limited in an apartment and this becomes a crucial problem if there are more than two bicycles for the owners of the apartment. 
     The present invention intends to provide a hanging device which occupies limited space and has a lot of pivotable support rods on which bicycles are convenient hanged. 
     SUMMARY OF THE INVENTION 
     In accordance with one aspect of the present invention, there is provided a hanging device which comprises a post and a leg assembly fixed to a lower end of the post. The leg assembly includes at least three pivotable legs which include at least one short leg. Each of the three legs has a bending portion. At least one set of support rod assembly is fixed to the post and at least one support rod is pivotably connected to the one set of support rod assembly. The primary object of the present invention is to provide a hanging device that is foldable so as to occupy only a limited space for the bicycles to be hanged in an upright direction. 
     The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to FIGS. 1 to  3 , the hanging device of the present invention comprises a post  10  which includes a first tube  11  and a second tube  12  which is retractably received in the first tube  11 . A control collar  15  employing a cam device (not shown) is connected to the first tube  11  so as to control the positioning of the second tube  12 . 
     A leg assembly  20  is fixed to a lower end of the post  10  and includes a frame  21  which is welded to the first tube  11  and three U-shaped members  211  are connected to the frame  21 . Each U-shaped member  211  has a fixing hole  213  and a pivoting hole  212  defined through each of two sidewalls thereof. Three legs  22 ,  23  are respectively engaged with the three U-shaped members  211  by extending a screw  214  through the pivoting holes  212  of each of the three U-shaped members  211  and a pivoting hole  231  of each of the three legs  22 ,  23  so that the three legs  22 ,  23  can be pivoted relative to the screws  214 . Farther referring to FIG. 7, a pin  215  extends through the fixing holes  213  of each of the three U-shaped members  211  and a fixing bole  232  of each of the three legs  22 ,  23  when the three legs  22 ,  23  are expanded horizontally. The leg  23  is a shot leg and the other two legs  22  are long legs. The short leg  23  is arranged to be put close to the wall so as to occupy less space. Each of the three legs  22 ,  23  has a bending portion which contacts the floor. 
     Two sets of support rod assembly  30  are fixed to the post  10  and each set includes a first fixing plate  31  and a second fixing plate  35 . The post  10  is clamped between the first fixing plate  31  and the second fixing plate  35  by using screws to connect the first fixing plate  31  and the second fixing plate  35 . Two support members  32  are connected to the first fixing plate  31  of each set of support rod assembly  30  and two support rods  34  are pivotably connected to the two support members  32  about the position  33 . Each of the support rods  34  includes a hooked distal end so that the bicycle frame  40  can be hanged on the hook distal ends as shown in FIG.  4 . The weight center of the bicycles  40  is located between the range of the bending portions of the legs  22  and the post  10  so that the hanging device will not fall. The bicycles  40  are hanged in an upright direction so that the space that occupied by the device and the bicycles  40  is efficiently reduced. 
     An auxiliary rod  14  is pivotably connected to a positioning member  13  which is fixed to the top of the post  10 . A pivoting hole  131  and a fixing hole  132  are defined through each of two sidewalls of the positioning member  13 . The auxiliary rod  14  is received between the two sidewalls of the positioning member  13  by extending a screw through the pivoting holes  131  of the positioning member  13  and a hole  141  defined through the auxiliary rod  14 . A pin  133  may extend through the fixing holes  132  of the positioning member  13  and a hole  142  defined through the auxiliary rod  14  when the auxiliary rod  14  is positioned at a horizontal position as shown in FIG. 5 which illustrates another way to use the hanging device, wherein the short leg  23  is also pivoted to let the bending portion of the short leg  23  contact the wall. By this arrangement, the distance between the wall and the post  10  is further reduced. 
     The hanging device can be conveniently folded to a compact size as shown in FIG. 6 which occupies only a small area and is suitable to smaller interior of rooms. 
     While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
