The disclosure relates to an electric table, particularly to an electric table, a leg stand, and a lightweight beam structure thereof.
According to different body types, body heights and users' habits, the tables of fixed types become obsolete. Electric lift tables with height adjustment have been the mainstream and the trend of modern designs. After adjusting the height, the tables can match users with different body heights and body types for comfort.
A related-art leg frame of an electric table includes a beam structure, a pair of telescopic posts and a pair of side wings. The beam structure is composed of two rectangular tubes connected at an interval and a receiving recess formed between the two rectangular tubes.
However, in order to make the leg frame possess considerable strength, connecting the rectangular tubes to constitute the beam structure not only requires complicated processes but also makes the finished leg frame have a heavy weight which is disadvantageous to being shifted and transported. Also, such a heavy weight makes the material costs unable to be effectively reduced to affect the economic profit.
In view of this, the inventors have devoted themselves to the above-mentioned related art, researched intensively and cooperated with the application of science to try to solve the above-mentioned problems. Finally, the disclosure which is reasonable and effective to overcome the above drawbacks is provided.
An object of the disclosure is to provide an electric table, a leg stand, and a lightweight beam structure thereof, which use the shapes of the frames to keep the stability, reduce the weight and decrease the material costs.
To accomplish the above object, the disclosure provides an electric table, which includes a leg frame, a table plate and multiple screwing elements. The leg frame includes a lightweight beam structure, a pair of telescopic posts and a pair of side wings. The lightweight beam structure includes a first frame and a second frame. The first frame includes an upper plate, a pair of inner side plates separately downward bent and extended from two sides of the upper plate, an outer side plate upward bent and extended from each inner side plate and a fixing plate bent and extended from each outer side plate. Each outer side plate is formed outside each inner side plate. A groove is formed between each inner side plate and each outer side plate. The second frame is connected with the first frame and includes a top plate and a pair of intermediate plates separately downward bent and extended from two sides of the top plate. Each intermediate plate is received in each groove. The top plate is formed over the upper plate. The telescopic posts are separately connected to two ends of the lightweight beam structure. Each telescopic post includes an electric motor. Each side wing is separately disposed on a side of each telescopic post. The table plate has a bottom surface. Each screwing element passes through the first frame and the second frame to attach each fixing plate and the top plate on the bottom surface.

The second frame is connected with the first frame and includes a top plate and a pair of intermediate plates separately downward bent extended from two sides of the top plate. The intermediate plates are separately received each groove. The top plate is formed over the upper plate.
The disclosure further has the following functions. By the co-planarity of each fixing plate, the top plate, the protrusion and the transverse plate of each side wing, and the rigidity of the table plate, the weight of the bean structure may be effectively reduced. By each intermediate plate being slidably connected to each groove, it may be widely applied for table plates with different lengths and specifications. By each telescopic post being pivotally connected to the beam structure, the time and labor costs in an installing scene may be saved.
The technical contents of this disclosure will become apparent with the detailed description of embodiments accompanied with the illustration of related drawings as follows. It is intended that the embodiments and drawings disclosed herein are to be considered illustrative rather than restrictive.

The first frame 10 is made by the processes of punching, blanking, and bending a metal plate. The first frame 10 includes an upper plate 11, a pair of inner side plates 12, a pair of outer side plates 13 and a pair of fixing plates 14. The inner side plates 12 are separately downward bent and extended from a front side and a rear side of the upper plate 11. Each outer side plate 13 is upward bent and extended from each inner side plate 12. Each outer side plate 13 is parallel to each inner side plate 12. Each fixing plate 14 is bent and extended from each outer side plate 13 for being attached on the table plate 8.
Each outer side plate 13 is formed outside each inner side plate 12. A groove 15 is formed between each inner side plate 12 and each outer side plate 13. Each fixing plate 14 has an upper surface 141. The upper plate 11 also has an upper surface 111. The upper surfaces of the fixing plates 14 are on the same plane and on a plane higher than that of the upper surface 111 of the upper plate 11.
In an embodiment, a left area of the upper plate 11 is formed with an alignment hole 112, and a right area of the upper plate 11 is provided with two stages 113. Each stage 113 has an upper surface 1131. The upper surface 1131 of each stage 113 and the upper surface 141 of each fixing plate 14 are substantially on the same plane. In addition, the outer stage 113 is formed with two locking holes 1132.
In an embodiment, multiple plugging holes 16 are respectively formed on each inner side plate 12 and each outer side 13 corresponding to each other. Each plugging hole 16 penetrates each inner side plate 12 and each outer side plate 13.
