Table structure
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.
The present invention relates to a table structure, and more particularly to an inclination-adjusting structure to facilitate the adjustment of the inclination and height of the table plate.
BACKGROUND OF THE INVENTIONGenerally speaking, the conventional inclination-adjustable worktable includes adjusting rods located under both sides of the table plate for adjusting the inclination of the table plate. However, this worktable that provides the simple and easy function for adjusting the inclination has a complicated structure, and the adjusting rods, which are protrudent from both sides of the worktable, are unsafe.
SUMMARY OF THE INVENTIONIt is a main object of the present invention to provide a multi-stage inclination-adjusting structure, wherein a coupling bracket is firmly mounted under a table plate for being coupled with an arc-shaped, disk-shaped plate, whereby an angle of inclination of the table plate is adjustable along the arc-shaped, disk-shaped plate. If the required angle is achieved, the positioning pillar is then inserted into a positioning hole. The table plate is adjustable steplessly by means of the arc-shaped coupling between the disk-shaped plate and the coupling bracket such that the user is allowed to make the stepless adjustment at any moment. For the positioning purpose, the positioning pillar is then inserted into the positioning hole. As a result, the present invention provides the featured step- or stepless-adjustment.
It is another object of the present invention to provide a structure that supports the weight of the table plate by a single pillar of the support bracket. In addition, the present invention further provides a power-saving, easily controllable elevating structure, which is hidden in the support bracket, for controlling the ascension and descension of the table plate. As a result, the table plate can be ascended or descended easily by merely controlling the control switches. Consequently, it is timesaving, power-saving and convenient to make the adjustment.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring to
The table plate 1 has a certain length on which several pen-holding slots 11 are formed on both corners of a table surface for holding pens or other articles to protect these articles from fall when the table plate 1 is inclined.
The coupling bracket 2 is firmly mounted under the table plate 1, and several slide chutes 21 are formed longitudinally on the coupling bracket 2. Besides, several positioning holes 22 are arranged in a row between two of the slide chutes 21.
The disk-shaped plate 3 is mounted under the coupling bracket 2, and the disk-shaped plate 3 has an arc-shaped surface 31. Two slide ribs 32 are formed on the arc-shaped surface 31 in the locations corresponding to the slide chutes 21 of the coupling bracket 2. Besides, a positioning pillar 35 is mounted on the arc-shaped surface 31 in the same direction as the positioning holes 22. A flat-reception bracket 33 is mounted on a rearward of the arc-shaped surface 31, and several through holes 34 are formed penetrating the arc-shaped surface 31. The slide ribs 32 can be inserted into the slide chutes 21 if the coupling bracket 2 is coupled with the disk-shaped plate 3, wherein several lock plates 36 are further mounted on the slide ribs 32, which are coupled with the slide chutes 21, for positioning the slide ribs 32 in the slide chutes 21. In addition, the positioning pillar 35 may be inserted into different positioning hole 22 such that the angle of inclination of the table plate 1 is changeable by shifting the coupling bracket 2.

Besides, a movable sleeve 41 consisting of an outer sleeve 411 and an inner sleeve 413 is mounted in the holding bracket 43. Two protrudent slides 412 are mounted longitudinally, oppositely on an inner surface of the outer sleeve 411 for being coupled with two recessed slides 414, which are mounted oppositely on an outer surface of the inner sleeve 413. The inner sleeve 413 is driven by the ascension or descension of the elevating device 5 to perform the corresponding movement since the disk-shaped plate 3 and the inner sleeve 413 are coupled with each other by the lock plates 36, which are locked to the top of the elevating device 5.
