Table with adjustable height and inclination

Abstract

A table with adjustable height and inclination includes a foot; a first support rack clutchably and pivotally combined with the foot; a second support rack clutchably and pivotally combined with the first support rack and fixed to a table board; a first positioning assembly rotatably disposed at a location of the pivotal combination between the first support rack and the foot for adjusting and fixing an angle of the first support rack swaying against the foot; and a second positioning assembly rotatably disposed at a location of the pivotal combination between the first support rack and the second support rack for adjusting and fixing an angle of the second support rack swaying against the first support rack.

What is claimed is: 
     
         1 . A table with adjustable height and inclination, comprising:
 a foot;   a first support rack clutchably and pivotally combined with the foot;   a second support rack clutchably and pivotally combined with the first support rack, the second support rack fixed to a table board simultaneously;   a first positioning assembly disposed at a location of a pivotal combination between the first support rack and the foot, the first positioning assembly moving between a fastened status and a loosened status to vary a status of the pivotal combination between the first support rack and the foot so as to adjust and fix an angle of the first support rack swaying against the foot; and   a second positioning assembly disposed at a location of a pivotal combination between the first support rack and the second support rack, the second positioning assembly moving between a fastened status and a loosened status to vary a status of the pivotal combination between the first support rack and the second support rack so as to adjust and fix an angle of the second support rack swaying against the first support rack.   
     
     
         2 . The table of  claim 1 , wherein when the first positioning assembly is at the fastened status, the first support rack pushes against the foot. 
     
     
         3 . The table of  claim 2 , wherein the first positioning assembly comprises a handle; when the first positioning assembly is at the fastened status, the handle pushes the first support rack, such that the first support rack pushes against the foot. 
     
     
         4 . The table of  claim 2 , wherein the first positioning assembly comprises a resilient member; when the first positioning assembly is at the loosened status, the first support rack laterally moves against the foot due to a resilient force of the resilient member of the first positioning assembly. 
     
     
         5 . The table of  claim 1 , wherein when the second positioning assembly is at the fastened status, the second support rack pushes against the first support rack. 
     
     
         6 . The table of  claim 5 , wherein the second positioning assembly comprises a handle; when the second positioning assembly is at the fastened status, the handle pushes the second support rack, such that the second support rack pushes against the first support rack. 
     
     
         7 . The table of  claim 5 , wherein the second positioning assembly comprises a resilient member; when the second support rack is at the loosened status, the second support rack laterally moves against the first support rack due to a resilient force of the resilient member of the second positioning assembly. 
     
     
         8 . The table of  claim 1 , wherein the first positioning assembly comprises a first pillar and a plurality of first grooves, such that the first support rack is engaged with the foot. 
     
     
         9 . The table of  claim 8 , wherein the first pillar is disposed on the first support rack, and the first grooves are disposed on the foot in an equiangular arrangement. 
     
     
         10 . The table of  claim 1 , wherein the second positioning assembly comprises a second pillar and a plurality of second grooves, such that the first support rack is engaged with the second support rack. 
     
     
         11 . The table of  claim 10 , wherein the second pillar is disposed on the first support rack, and the second grooves are disposed on the second support rack in an equiangular arrangement.
