1. Field of the Invention
The present invention relates to a table and chair device, and more particularly to a multi-functional table and chair device that allows different users to carry out different activities such as sitting, lying, resting and dining.
2. Description of Related Art
Passengers in public transports such as trains, high speed rail trains, metro trains or airplanes often sit for a long time and even needs to dine and sleep on seats. Therefore comfortableness and additional functions that a seat can provide to a passenger are important.
Each of conventional chairs of public transports usually has a footrest and armrests to allow a passenger to rest his/her feet or arms thereon. The chairs are arranged tandem and each chair has a folding table mounted pivotally on a rear thereof so that a passenger sitting on a rear chair is able to fold downward the folding table on the front chair for 90 degrees to dine or read on the folding table. However, the footrest is inclined when extended out instead of being horizontal so that the passenger is not allowed to lie down flatly and comfortably sleep. Furthermore, the table cannot be adjusted and held in different levels, which does not suit for different passengers.
To overcome the shortcomings, the present invention provides a multi-functional table and chair device to mitigate or obviate the aforementioned problems.
The main objective of the invention is to provide a multi-functional table and chair device that allows different users to carry out different activities such as sitting, lying, resting and dining.
A multi-functional table and chair device in accordance with the present invention has a base, two opposite chair sets mounted on the base, and an adjustable table. Each chair set has at least one chair, and each chair has a supporting bracket, a seat, a backrest and a footrest. The adjustable table is mounted on the base between the chair sets and has a bottom bracket, an elevation mechanism and a table board. When the backrest of the chair is pivoted backward and the footrest is unfolded, the chair is changed into a deck chair. When the footrests of two opposite chairs of the chair sets are pivoted upward and unfolded to be horizontal and the adjustable table is raised to hold the footrests, the two opposite chairs and the adjustable table form a bed.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

With further reference to
The chair sets are mounted on the base 10 and each chair set has at least one chair 20. In a preferred embodiment of the present invention, each chair set has two chairs 20 arranged abreast. Each chair 20 has a rail 200, a supporting bracket 21, a seat 22, a backrest 23, a footrest 24 and two armrests 25.
The rail 200 is mounted securely on the base 10.
The supporting bracket 21 is mounted on the base 10, may be mounted slidably on the rail 200 and is capable of sliding back and forth relative to the rail 200.
The seat 22 is mounted slidably on a top of the supporting bracket 21 and is capable of sliding back and forth relative to the supporting bracket 21.
The backrest 23 is mounted pivotally on a rear end of the seat 22.
The footrest 24 is mounted pivotally on a front end of the seat 22 and has a rest plate 241 and an extension plate 242. The rest plate 241 is mounted pivotally on the front end of the seat 22. The extension plate 242 is mounted pivotally on a front end of the rest plate 241.
The armrests 25 are mounted respectively on opposite sides of the backrest 23.

The bottom bracket 31 is mounted on the base 10.
The elevation mechanism 32 is mounted on the bottom bracket 31 and is capable of extending or retracting vertically.
The table board 33 is mounted on a top of the elevation mechanism 32 and is selectively raised or lowered to be higher than the seat 22, aligned with the seat 22, or lower than the seat 22. The table board 33 has two extension boards 35. The extension boards 35 are pivotally mounted respectively on two opposite sides of the table board 33 and are selectively folded and stacked on the table board 33 or unfolded outward to be horizontal.

The multi-functional table and chair device of the present invention has the following advantages.
1. The adjustable table 30 may be raised or lowered to different levels according to different users. Alternatively, the adjustable table 30 may be lowered and retracted adjacent to the base 10 when idle. The chair 20 allows the user to sit thereon. Alternatively, pivoting the backrest 23 backward and unfolding the footrest 24 changes the chair 20 into a deck chair. Alternatively, the footrests 24 of the two opposite chairs 20 are unfolded to be horizontal and are held by the elevated adjustable table 30 to form a flattened bed. Therefore, the multi-functional table and chair device provides users with different functions.
2. The sliding supporting bracket 21 on the base 10 and the sliding seat 22 on the supporting bracket 21 allow different distances between each chair 20 and the adjustable table 30 for different users with different figures and habits.
3. The adjustable table 30 may be raised or lowered according to different users.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
