Title: Foldable table

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a foldable table. More particularly, the present invention relates to a foldable table which has a plastics table plate made by a blow molding method. 
     A conventional foldable table is very heavy. Thus it is difficult to carry the conventional foldable table to walk a long distance for a user. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide a foldable table which has a plastics table plate to receive four leg tubes so that the foldable table will be in a compact configuration while the leg tubes are folded. 
     Another object of the present invention is to provide a foldable table which has a plastics table plate made by a blow molding method in order to reduce a weight of the plastics table plate. 
     Accordingly, a foldable table comprises a plastics table plate, a hoop-shaped frame, four corner seats disposed on four corners of the hoop-shaped frame, four leg tubes, and a plurality of fastening members. Each of the leg tubes is disposed on the corresponding corner seat. A center panel is disposed on the plastics table plate. The plastics table plate has a periphery flange and a periphery channel. Four protrusions are disposed on the center panel. Four protruded blocks are disposed on the plastics table plate. Four square blocks are disposed on four corners of the plastics table plate. A plurality of nuts are implanted in the periphery channel of the plastics table plate. The hoop-shaped frame has a plurality of through holes. Each of the corner seats has a groove and an elastic blocking angle bar. At least a connection bar is connected to the corresponding corner seat and the corresponding leg tube pivotally. At least a connection plate is connected to the corresponding elastic blocking angle bar and the corresponding leg tube pivotally. The hoop-shaped frame is inserted in the plastics table plate and confined by the periphery flange of the plastics table plate. Each of the square blocks is inserted in the corresponding groove of the corner seat.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to FIGS. 1 to  7 , a foldable table comprises a plastics table plate  1 , a hoop-shaped frame  21 , four corner seats  22  disposed on four corners of the hoop-shaped frame  21 , four leg tubes  25 , and a plurality of fastening members  27 . Each of the leg tubes  25  is disposed on the corresponding corner seat  22 . 
     A center panel  11  is disposed on the plastics table plate  1 . 
     The plastics table plate  1  has a periphery flange  12  and a periphery channel  10 . 
     Four protrusions  15  are disposed on the center panel  11 . 
     Four protruded blocks  14  are disposed on the plastics table plate  1 . 
     Four square blocks  16  are disposed on four corners of the plastics table plate  1 . 
     A plurality of nuts  13  are implanted in the periphery channel  10  of the plastics table plate  1 . 
     The hoop-shaped frame  21  has a plurality of through holes  211 . 
     Each of the corner seats  22  has a groove  26  and an elastic blocking angle bar  221 . 
     At least a connection bar  23  is connected to the corresponding corner seats  22  and the corresponding leg tube  25  pivotally. 
     At least a connection plate  24  is connected to the corresponding elastic blocking angle bar  221  and the corresponding leg tube  25  pivotally. 
     The hoop-shaped frame  21  is inserted in the plastics table plate  1  and confined by the periphery flange  12  of the plastics table plate  1 . 
     Each of the square blocks  16  is inserted in the corresponding groove  26  of the corner seat  22 . 
     Each of the fastening members  27  passes through the corresponding through hole  211  of the hoop-shaped frame  21  and the corresponding nut  13 . 
     The plastics table plate  1  is made by a blow molding method. 
     Referring to FIGS. 5 and 7 again, the leg tubes  25  are extended. 
     Referring to FIG. 3 again, the leg tubes  25  are folded. 
     Each of the leg tubes  25  is confined by the corresponding protrusion  15  and the corresponding protruded block  14 . 
     The invention has the following advantages. The plastics table plate is made by a blow molding method in order to reduce a weight of the plastics table plate. The nuts are implanted in the periphery channel of the plastics table plate in advance, so it is easy to assemble the foldable table. The corner seats reinforce a strength of the plastics table plate. The connection bar and the connection plate stabilize the corresponding leg tube. The plastics table plate receives the leg tubes so that the foldable table will be in a compact configuration while the leg tubes are folded. 
     The invention is not limited to the above embodiment but various modification thereof may be made. Further, various changes in form and detail may be made without departing from the scope of the invention.
