Abstract
A foldable table has a plastics table plate, a hoop-shaped frame, four corner seats disposed on four corners of the hoop-shaped frame, and four leg tubes. Each leg tube 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 square blocks are disposed on four corners of the plastics table plate. Each corner seat 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. At least a connection plate is connected to the corresponding elastic blocking angle bar and the corresponding leg tube. The hoop-shaped frame is inserted in the plastics table plate. Each square block is inserted in the corresponding groove of the corner seat.
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.
