     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0017]     The collapsible closet frame, as shown in  FIG. 1 , comprises pillars  1 , posts  2 , first lining rod sets  3 , second linking rod sets  4  and third linking rod sets  5 .  
         [0018]     The pillars  1  are at four corners of the closet frame, and each is seated on a corresponding post  2 . Wherein the top end of each pillar  1  is secured with a first bracket  11  and the bottom end of each pillar  1  is secured with a second bracket  12 . A first sliding bracket  13  and a second sliding bracket  14  are set between the first bracket  11  and the second bracket  12 . The first bracket  11  and the second bracket  12  are identical in structure, therefore, only one drawing is shown in  FIG. 2 . The first bracket  11  comprises a first connecting end  111 , a second connecting end  112 , a clip  113 , and an arcuate groove  114 . The second bracket  12  comprises a first connecting end  121 , a second connecting end  122 , a clip  123 , and an arcuate groove  124 . The first sliding bracket  13  and the second sliding bracket  14  are both identical in structure, and only one drawing is shown in  FIG. 3 . The first sliding bracket  13  comprises a first connecting end  131 , a second connecting end  132 , a hole  133 , and an arcuate groove  134 . The second sliding bracket  14  comprises a first connecting end  141 , a second connecting end  142 , a hole  143 , and an arcuate groove  144 .  
         [0019]     Each of the posts  2 , as shown in  FIG. 4 , is in an arcuate shape in order to slip into the arcuate groove  124  of the second bracket  12  which may slide along the post  2 . The top end of the post  2  is securely connected to the second sliding bracket  14 , and the pillar  1  is slipped into the second sliding bracket  14  in a sliding manner, thus the pillar  1  is able to expand or retract with respect to the post  2 .  
         [0020]     Each of the first linking rod sets  3  is formed with two rods  31  with the center portion connected with each other to form an X-shaped member. Every two X-shaped members are connected again to form a scissors-type structure. Each scissors-type structure has a first connecting end  32 . There are four first linking rod sets  3  pivoted to both the upper and the lower ends of the pillars  1 , and they are in an opposite position with each other. The first linking rod set  3  located at the upper ends between the two pillars  1  has their four ends pivoted to the first connecting end  111  of the first bracket  11  and the first connecting end  131  of the first sliding bracket  13 . The first linking rod set  3  located at the lower ends between the two pillars  1  has their four ends pivoted to the first connecting end  121  of the second bracket  12  and the first connecting end  141  of the second sliding bracket  14 .  
         [0021]     Each of the second linking rod sets  4  is formed by two crossed rods  41  to form an X shape. The connection area of the two rods  41  has a second connecting end  42 . There are four second linking rod sets  4  pivoted to both the upper and the lower ends between every two pillars  1 . The second linking rod set  4  located on the upper ends of the pillars  1  has its four ends pivoted to the second connecting end  112  of the first bracket  11  and to the second connecting end  132  of the first sliding bracket  13 , respectively, whereas the four ends of the second linking rod set  4  located on the lower ends of the pillars  1  are connected to the second connecting end  122  of the second bracket  12  and to the second connecting end  142  of the second sliding bracket  14 , respectively. The second connecting end  42  of the second linking rod set  4  located on the upper ends of the pillars  1  is provided with a cross bar  43  with a hole  44  at one end thereof.  
         [0022]     There are two third linking rod sets  5 . Each third linking rod set  5  is also formed by a pair of rods  51  and is connected in an X-shaped type. The connecting area of the two rods  51  has a third connecting end  52 . The third connecting end  52  of the upper third linking rod set  5  is formed with hooks  53  at respective ends, as shown in  FIG. 5 . The four ends of the third linking rod set  5  are connected to the four first connecting ends  32  of the first linking rod sets  3 , respectively.  
         [0023]     In operation, as shown in  FIG. 6 , the four posts  2  are expanded outwardly at four corners, whereas the first sliding brackets  13  on the four pillars  1  will slide upward along the pillars  1  to the underneath of the first brackets  11 , and the second brackets  12  link the pillars  1  to raise till the second brackets  12  has reached the underneath of the second sliding brackets  14 , wherein the first linking rod sets  3 , the second linking rod sets  4 , and the third linking rod sets  5  are forced to expanded, as shown in  FIGS. 7 and 8 . That brings the clips  113  of the first brackets  11  and the clips  123  of the second brackets  12  into the holes  133  and  143  of the first sliding brackets  13  and the second sliding bracket  14 , respectively. Thus the first linking rod sets  3 , the second linking rod sets  4 , and the third linking rod sets  5  are expanded entirely and prevent from sliding randomly. As shown in  FIG. 9 , the cross bars  43  of the second linking rod sets  4  have its holes  44  at the far ends hooked with the hooks  53  of the third linking rod set  5 . The cross bars  43  are between the second linking rod sets  4  and the third linking rod set  5 , so that clothes hangers  7  may be hanged on the cross bars  43 . Place a cover  6  on the outside of the closet of the present invention, as shown in  FIG. 10 , and the present invention is completed with the assembly.  
         [0024]     To collapse the present invention, as shown in  FIG. 11 , simply take off the cover  6  and unhook the holes  44  of the cross bars  43  from the hooks  53 , then disengage the clips  113  and  123  of the first brackets  11  and the second brackets  12  from the holes  133  and  143  of the first sliding brackets  13  and the second sliding brackets  14 , push the pillars  1  towards each other, and the first sliding brackets  13  will slide along the pillars  1  downwardly, and the second brackets  12  will link the pillars  1  to move downward to the bottom ends of the posts  2 . Whereas the first linking rod sets  3 , the second linking rod sets  4 , and the third linking rod sets  5  are collapsed. Upon the four posts  1  has reached to the centermost position, as shown in  FIG. 11 , the collapsible procedure is completed.
