Title: Basket Drawer Structure

Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to a cabinet for accommodating objects (such as clothes) and, more particularly, to a basket drawer which pulls rollers easily. 
     Description of the Prior Art 
     A conventional cabinet is applied to accommodate objects and contains a drawer fixed across a rail, so the drawer is pulled difficultly because of pulling resistance. To decrease the pulling resistance, the conventional cabinet contains a drawer, two rails, and two rollers arranged on the two rails respectively, such that the drawer is pulled easily. However, the two rollers are arranged on the two rails respectively, thus occupying storage space and increasing manufacture cost. 
     A conventional basket drawer contains a hollow accommodation space, and two rollers are arranged on two rails of the cabinet, thus having an unattractive appearance. Furthermore, it is not easy to form the two rails on cables of the basket drawer, so the two rollers are arranged on the two rails of the conventional cabinet. The basket drawer when loaded cannot be pulled easily. 
     The present invention has arisen to mitigate and/or obviate the afore-described disadvantages. 
     SUMMARY OF THE INVENTION 
     The primary objective of the present invention is to provide a basket drawer structure in which a peripheral rib has two recessed portions respectively formed on two rear ends of two outer sides of the basket. Two orifices are defined inside the two recessed portions individually, and two first rollers are rotatably riveted on the two recessed portions respectively. Hence, the two first rollers of the basket correspond to two rail elements respectively, and two second rollers of the two rail elements correspond to the basket, so that the basket is supported and rolls by way of the two first rollers and the two second rollers, thus pulling the basket smoothly. 
     To obtain the above-mentioned objective, a basket drawer structure provided by the present invention contains: a basket and two rail elements. 
     The basket includes a mesh formed on a lower end of the basket, a holding space defined in the basket, an opening formed on an upper end of the basket, and a peripheral rib arranged around the opening and to have a square cross section of the peripheral rib. An inner wall of the peripheral rib connects with the mesh. The peripheral rib has two recessed portions respectively formed on two rear ends of two outer sides of the basket. The two recessed portions define two depths, two orifices are defined inside the two recessed portions individually, and two first rollers are rotatably riveted on the two recessed portions respectively. The two recessed portions have two shaft holes defined thereon individually, and two rivets insert through the two shaft holes to rivet with two centers of the two first rollers individually. Hence, the two first rollers are rotatably riveted on the two recessed portions respectively, and the two orifices of the two recessed portions provide two riveting spaces to the two first rollers individually. 
     The two rail elements are spaced and symmetrically fixed on a shelf or a cabinet. A distance between the two rail elements is equal to a width of the basket. The two rail elements respectively include two support rails arranged on two inner sides of the two rail elements. Two second rollers are riveted on two front ends of the two support rails individually. The basket is retained in the two support rails by way of the peripheral rib, and the two second rollers of the two rail elements are mounted in the peripheral rib.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustration only, preferred embodiments in accordance with the present invention. 
     With reference to  FIGS. 1 to 4 , a basket drawer structure according to a preferred embodiment of the present invention comprises: a basket  10  and two rail elements  20 . 
     The basket  10  includes a mesh  11  formed on a lower end thereof, a holding space  111  defined in the basket  10 , an opening  112  formed on an upper end of the basket  10 , and a peripheral rib  12  arranged around the opening  112  to have a square cross section of the peripheral rib  12 . An inner wall of the peripheral rib  12  connects with the mesh  11 . The peripheral rib  12  has two recessed portions  13  respectively formed on two rear ends of two outer sides of the basket  10 . The two recessed portions  13  define two depths H 0 , two orifices  14  are defined inside the two recessed portions  13  individually, and two first rollers  15  are rotatably riveted on the two recessed portions  13  respectively. The two orifices  14  of the two recessed portions  13  provide two riveting spaces to the two first rollers  15  individually. 
     The two rail elements  20  are spaced and symmetrically fixed on a shelf or a cabinet. A distance between the two rail elements  20  is equal to a width of the basket  10 . The two rail elements  20  respectively include two support rails  21  arranged on two inner sides of the two rail elements  20 . Two second rollers  22  are riveted on two front ends of the two support rails  21  individually. The basket  10  is retained in the two support rails  21  by way of the peripheral rib  12 , and the two second rollers  22  of the two rail elements  20  are mounted in the peripheral rib  12 , so that two rail elements  20  support the basket  10 . The two first rollers  15  of the basket  10  are accommodated in the two support rails  21 , so that the two rail elements  20  support the basket  10 . 
     When the basket  10  is fixed between the two rail elements  20 , two front ends of the two rail elements  20  support the basket  10  by using the two second rollers  22 , and a rear end of the basket  10  supports the two rail elements  20  by way of the two first rollers  15 . 
     Referring to  FIGS. 3-5 , the peripheral rib  12  of the basket  10  reinforces the basket  10 , and the two recessed portions  13  facilitate accommodation of the two first rollers  15 , so that the two first rollers  15  do not extend or do not overly extend out of the two recessed portions  13 , thus saving space and reinforcing the basket  10 . 
     As shown in  FIGS. 4, 6 and 7 , the two recessed portions  13  of the peripheral rib  12  of the basket  10  have two shaft holes  131  defined thereon individually. Two rivets  151  insert through the two shaft holes  131  to rivet with two centers of the two first rollers  15  individually. Two first rollers  15  are rotatably riveted on the two recessed portions  13  respectively, and the two first rollers  15  do not extend over the two depths H 0  of the two recessed portions  13  individually 
     Accordingly, the two first rollers  15  of the basket  10  correspond to the two rail elements  20  respectively, and the two second rollers  22  of the two rail elements  20  correspond to the basket  10 , so that the basket  10  is supported and rolls by way of the two first rollers  15  and the two second rollers  22 , thus pulling the basket  10  smoothly and saving effort. 
     While various embodiments in accordance with the present invention have been shown and described, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
