Article Support Rack

Abstract

A telescopic article support rack includes a primary article support rack, a secondary article support rack, and a clamp. A slide guiding device is disposed between the primary and the secondary article support racks for guiding the primary and the secondary article support racks slide relative with each other. One end of the clamp buckles on the primary article support rack, and the other end buckles on the secondary article support rack when the secondary article support rack is pulled or pushed to a needed position so as to make the primary and the secondary article support racks fixed relatively. The clamp is a double-faced clamp that can fix something in two opposite directions. Since the secondary article support rack can be extended or telescoped freely, the article support rack not only can meet the user's requirement of placing more objects, but also can avoid wasting room space when there is no need for placing more objects.

1 . An article support rack comprising:
 a primary article support rack having a first shelf-board and a plurality of support legs joined to the first shelf-board, the first shelf-board forming a first rail;   a secondary article support rack having a second shelf-board and a plurality of support legs joined to the second shelf-board, the second shelf-board forming a second rail and a third rail;   a slide guiding device disposed between the primary article support rack and the secondary article support rack for guiding the primary article support rack and the secondary article support rack slide relative with each other; and   a clamp, one end of the clamp forming a first split ring, the other end of the clamp forming a second split ring and a third split ring which are symmetrical and have opposite splits, the first split ring buckling on the first rail of the primary article support rack, the second split ring and the third split ring selectively buckling on the corresponding rails of the secondary article support rack;   wherein an inner diameter of the first split ring is larger than an outer diameter of the first rail, an inner diameter of the second split ring is larger than an outer diameter of the second rail, and an inner diameter of the third split ring is larger than an outer diameter of the third rail.   
   
   
       2 . The article support rack as claimed in  claim 1 , wherein the slide guiding device comprises a track bracket formed on the primary article support rack for guiding the secondary article support rack slide inside the primary article support rack, the track bracket is located under the first shelf-board of the primary article support rack, and the secondary article support rack further comprises limiting beams extruding from the second shelf-board for limiting the secondary article support rack in right and left direction when sliding the secondary article support rack relative to the primary article support rack and defining a maximum extension position of the secondary article support rack when extending the secondary article support rack. 
   
   
       3 . The article support rack as claimed in  claim 2 , wherein the limiting beams of the secondary article support rack are provided at least two. 
   
   
       4 . The article support rack as claimed in  claim 3 , wherein the track bracket of the primary article support rack comprises two tracks and two support beams. 
   
   
       5 . The article support rack as claimed in  claim 4 , wherein the length of the support beam of the track bracket is larger than the distance between the two limiting beams of the secondary article support rack, and the distance between the two limiting beams is larger than that between the two tracks of the track bracket. 
   
   
       6 . The article support rack as claimed in  claim 5 , wherein the length of the limiting beam of the secondary article support rack is smaller than the distance between the support beam of the track bracket and the first rail of the first articles shelf-board of the primary article support rack. 
   
   
       7 . The article support rack as claimed in  claim 1 , wherein the slide guiding device is a pulley module for drawer having a slide track positioned on the primary article support rack and a slider positioned on the secondary article support rack. 
   
   
       8 . The article support rack as claimed in  claim 1 , wherein the secondary article support rack further comprises a plurality of rails configured to be buckled on by the second split ring and the third split ring of the clamp selectively. 
   
   
       9 . The article support rack as claimed in  claim 8 , wherein the primary article support rack and the secondary article support rack each further comprise a plurality of shelf-boards. 
   
   
       10 . The article support rack as claimed in  claim 9 , wherein each support leg of the primary article support rack and the secondary article support rack has a truckle.
