Description

FIELD OF THE INVENTION

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 INVENTION

Generally 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 INVENTION

It 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1 through FIG. 3, a table structure comprises a table plate 1, a coupling bracket 2, a disk-shaped plate 3, a support bracket 4 and an elevating device 5, wherein an inclination-adjusting structure for ascension and descension of the table plate is composed of the coupling bracket 2 and the disk-shaped plate 3.

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.

Referring again to FIG. 3, FIG. 5 and FIG. 7, the support bracket 4, which is sufficient to support the weight of table plate 1 is mounted under the disk-shaped plate 3, wherein a holding bracket 43 having a positioning sleeve 431 on the center thereof is centrally mounted on the support bracket 4. In addition, the elevating device 5 is held by the positioning sleeve 431. The elevating device 5 is, for example, a hydraulic elevator, a pneumatic elevator, an automatic elevating device or other elevating structure.

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.

Referring to FIG. 2 through FIG. 4, FIG. 6 and FIG. 8, the diagrams for explaining the adjustment of the inclination of the table plate 1 are shown. In order to adjust the angle of inclination of the table plate 1, the positioning pillar 35 is driven by a first control switch 6 located under the table plate 1 to shrink into the disk-shaped plate 3, so that the positioning pillar 35 is separated from the through hole 34 of the coupling bracket 2, whereby the table plate 1 is shiftable along the arc-shaped surface 31 by means of the coupling bracket 2. When the table plate 1 is shifted, the slide ribs 32 are slidable along the slide chutes 21 of the coupling bracket 2. When the table plate 1 is inclined forward to a maxi-angle position, the slide ribs 32 can be blocked by rear walls 211 of the slide chutes 21. In addition, the angle of inclination of the table plate 1 can be fixed securely by inserting the positioning pillar 35 into one of the positioning holes 22.

As shown in FIG. 2 and FIG. 8, when the table plate 1 is in horizontal plane, the flat-reception surface 23 of the coupling bracket 2 is confined by the flat-reception bracket 33 to keep the table plate 1 horizontal.

Referring to FIG. 4 through FIG. 7, the elevating structure for adjusting the height of the table plate 1 is shown. The weight of the table plate is focused, supported by a single pillar of the support bracket 4. In addition, the elevating device 5 hidden in the support bracket 4 can be controlled by a second control switch 7 mounted under the table plate 1. As a result, the table structure can be operated easily by the user since the first control switch 6 and the second control switch 7 are both mounted under the table plate 1. By controlling the elevating device 5, the disk-shaped plate 3, the coupling bracket 2 and the table plate 1 are driven for motions simultaneously such that the inner sleeve 413, which is firmly coupled with the elevating device 5, is allowed to slide along the protrudent slides 412 of the outer sleeve 411, whereby the height of the table plate 1 is adjustable.

Furthermore, a bookrack 8 is mounted on a rearward of the table plate 1 to provide the user with the convenience in placing books and articles.
