A known plastic table top has a single thick plate or two layers of thin plates. These table tops are blow molding types and vacuum forming types. These hollow table tops have a top plate and a bottom plate stacked together. A metal frame is disposed at the inner side of the periphery of the stacked top plate and the bottom plate. Existing vacuum forming table tops need vertical flanges at the inner side of the periphery of the top and bottom plate to cover the metal frame. The joint of the top plate and the bottom plate is exposed. In use fingers or clothes may be caught or clamped by the vertical flanges, causing injury or damaging clothes or the vertical flanges. This kind of embedded metal frame only acts to increase strength and connect the support elements but it cannot protect the connecting points of the top plate and the bottom plate.
A frame structure of a table top with stable structure and high security overcomes the disadvantages of the related art. A hollow table top has a top plate and a bottom plate, the bottom plate is disposed with projections or concave features. The edge of the bottom surface of the table top is disposed with a metal frame, the edge of the top plate extends downwardly. The metal frame is disposed with a protruding portion in the horizontal direction extending out of the top plate side.
In another preferred embodiment, the protruding portion of the metal frame is a crimping bending upwardly and covers the bottom portion of top plate side.
In another preferred embodiment, the protruding portion of the metal frame is closed to the bottom portion of the top plate side. In another preferred embodiment, the bottom portion of the top plate side bends towards the metal frame. The side surface of the hollow table top is substantially a plane.
In another preferred embodiment, the edge of the bottom plate is disposed with a downwardly extending bottom plate side. The crimping covers the bottom portion of the bottom plate side. In another preferred embodiment, the bottom portion of the bottom plate side bends towards the metal frame.
In another preferred embodiment, the bottom portion of the bottom plate is disposed with a downwardly extending fixing portion. The fixing portion is disposed at the side of the top plate side opposite to the metal frame. A screw laterally passes through the fixing portion to lock to the metal frame.
Compared to the existing known technology, advantages are:
1. The external side of the metal frame extends out of the top plate side, and covers the bottom portion of the top plate side or abuts against the bottom portion of the top plate side. When being used, the bottom portion of the top plate is not folded up, improving the integration of the table top. Fingers or clothes are not clamped by the vertical flange. At the same time, the crimping covers the top plate side.
2. The metal frame is detachably locked to the bottom plate, the structure is simple and more stable.
Referring to
The edge of the top plate 11 is disposed with a downwardly extending top plate side 112. The bottom portion of the top plate side 112 bends towards the metal frame 13. The edge of the bottom plate 12 is disposed with a downwardly extending bottom plate side 12. The bottom portion of the bottom plate side 122 bends towards the metal frame 13. The top plate side 112 and the bottom plate side 122 are contacted together. The metal frame 13 has a protruding portion, which, in this embodiment is a crimping 132 bending upwardly from the bottom portion of the top plate side 112. The crimping 132 covers the bottom portion of the top plate side 112 and the bottom plate side 122.
The bottom portion of the top plate side and the bottom plate side bend towards the metal frame so as to make space for the crimping and keep the crimping and the external edge of the crimping vertically aligned, so the side surface is in a plane and the table top attractive.

The edge of the top plate 11 is disposed with a downwardly extending top plate side 112. The edge of the bottom plate 12 is disposed with a downwardly extending bottom plate side 122. The top plate side 112 and the bottom plate side 122 are in contact and attached together. The metal frame 13 is disposed with a protruding portion 131, which is a substantially lateral straight edge at the bottom portion of the metal frame. The bottom portion of the top plate side 112 ends at the protruding portion 131 of the metal frame.
