Table structure

Abstract

An inclination-adjusting structure is mounted on a lower portion of a table structure. A coupling bracket is firmly mounted under a table plate. Several slide chutes are formed longitudinally on the coupling bracket. Several positioning holes are arranged in a row between two of the slide chutes. A disk-shaped plate is mounted under the coupling bracket. The disk-shaped plate has an arc-shaped surface. Two slide ribs are formed on the arc-shaped surface in locations corresponding to the slide chutes of the coupling bracket. A positioning pillar is mounted on the arc-shaped surface in the same direction as the positioning holes. The slide ribs are inserted into the slide chutes if the coupling bracket is coupled with the disk-shaped plate. The positioning pillar can be inserted into different positioning hole. In addition, an angle of inclination of the table plate is adjustable by shifting the coupling bracket.

1 . A table structure comprising: 
 a table plate, a coupling bracket, a disk-shaped plate and a support bracket, wherein the coupling bracket and the disk-shaped plate collectively constitute an inclination-adjusting structure for ascension and descension of the table plate,    wherein the coupling bracket is firmly mounted under the table plate, a plurality of slide chutes are formed longitudinally on the coupling bracket and a plurality of positioning holes are arranged in a row between two of the slide chutes, and    wherein the disk-shaped plate is mounted under the coupling bracket, the disk-shaped plate has an arc-shaped surface, two slide ribs are formed on the arc-shaped surface in locations corresponding to the slide chutes of the coupling bracket, a positioning pillar is mounted on the arc-shaped surface in the same direction as the positioning holes and a flat-reception bracket is mounted on a rearward of the arc-shaped surface, whereby the slide ribs are inserted into the slide chutes if the coupling bracket is coupled with the disk-shaped plate, and whereby an angle of inclination of the table plate is adjustable by shifting the coupling bracket such that the positioning pillar can be inserted into different positioning hole.    
   
   
       2 . The table structure of  claim 1 , wherein the positioning pillar, which is located between the disk-shaped plate and the coupling bracket, is controlled by a first control switch to be separated from or inserted into one of the positioning holes.  
   
   
       3 . A table structure comprising: 
 a table plate, a coupling bracket, a disk-shaped plate, a support bracket and an elevating device, wherein the coupling bracket and the disk-shaped plate collectively constitute an inclination-adjusting structure for ascension and descension of the table plate,    wherein the coupling bracket is firmly mounted under the table plate, a plurality of slide chutes are formed longitudinally on the coupling bracket and a plurality of positioning holes are arranged in a row between two of the slide chutes,    wherein the disk-shaped plate is mounted under the coupling bracket, the disk-shaped plate has an arc-shaped surface, two slide ribs are formed on the arc-shaped surface in locations corresponding to the slide chutes of the coupling bracket, a positioning pillar is mounted on the arc-shaped surface in the same direction as the positioning holes and a flat-reception bracket is mounted on a rearward of the arc-shaped surface, whereby the slide ribs are inserted into the slide chutes if the coupling bracket is coupled with the disk-shaped plate, and whereby an angle of inclination of the table plate is adjustable by shifting the coupling bracket such that the positioning pillar can be inserted into different positioning hole, and    wherein a holding bracket is mounted inside the support bracket, the holding bracket has a movable sleeve mounted therein, the movable sleeve is consisted of an outer sleeve and an inner sleeve, two protrudent slides are mounted longitudinally, oppositely on an inner surface of the outer sleeve for being coupled with two recessed slides mounted oppositely on an outer surface of the inner sleeve, whereby the inner sleeve is driven by ascension or descension of the elevating device to perform the corresponding movements.    
   
   
       4 . The table structure of  claim 3 , wherein the bottom of the elevating device is firmly coupled with a positioning sleeve located on a center region of the holding bracket of the support bracket, and a lock plate is coupled with a top end of the elevating device and located firmly between the disk-shaped plate and the inner sleeve.  
   
   
       5 . The table structure of  claim 3 , wherein the elevating device is controlled by a second control switch mounted under the table plate for ascension or descension.
