Framework Retaining Structure

Abstract

A framework retaining structure includes two sliding units, four end pieces and two rail units. A positioning groove is provided on the upper surface and the lower surface of each sliding unit. An end piece is connected to the right end and the left end of each sliding unit. A substantially “L” shaped indentation portion is provided on each end piece. Therefore, an item rack, a clothes rack or other types of framework may be engaged with the positioning grooves. Also, the rack or framework may be disengaged from the positioning grooves easily. The rear surface of each sliding unit is connected with a rail unit, and the two rail units are fixed inside a closet, a cabinet or other type of furniture so that the rack may be extended out of the closet or cabinet.

1 . A framework retaining structure, comprising:
 two rail units, able to be extended;   two sliding units, with a hollow passage extending through full length of each sliding unit and with a positioning groove provided on an upper surface or/and a lower surface of the hollow passage; and   four end pieces, each of which having an end cap and a sliding portion, with a flexible affixing piece provided on the front surface of the sliding portion and with an indentation portion provided near where the sliding portion meets the end cap,   wherein the flexible affixing piece is inserted into the hollow passage of the sliding unit so as to affix the end piece to the sliding unit and seal the hollow passage and so that the indentation portion is in parallel with the positioning groove, and after each sliding unit is connected with the corresponding rail unit, the two outermost rail piece is fixed inside a closet or a cabinet so that the peripheral parts of an item rack or a clothes rack is easily engaged with the positioning grooves of the sliding units or the indentation portions of the end pieces.   
   
   
       2 . The framework retaining structure as in  claim 1 , wherein each rail unit has several rail pieces so that the rail units is extended. 
   
   
       3 . The framework retaining structure as in  claim 1 , wherein each sliding unit is connected with the corresponding rail unit and two end pieces by screws. 
   
   
       4 . The framework retaining structure as in  claim 1 , wherein a retaining groove is provided on the rear surface of each sliding unit and the rear surface of each sliding portion and a width of the retaining groove of the sliding portion is smaller than a width of the retaining groove of the sliding unit so that the sliding portion and the end pieces are connected with the rail unit. 
   
   
       5 . The framework retaining structure as in  claim 1 , wherein the indentation portion of each end piece is substantially “L” shaped. 
   
   
       6 . The improved framework retaining structure as in  claim 1 , wherein the cross section of the positioning groove is substantially “ ” shaped after a sliding unit is joined with two end pieces.
