DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiment 1

FIG. 1 shows an explored view and partly sectional view of the preferred embodiment 1 according to the invention. The composite table top 10 that is to use vacuum forming material comprises a face plate 100, a reinforcement plate 200 and a reinforcement frame 300. The face plate 100 is a kind of surface plate with upward flange on the outer peripheral edges. The reinforcement plate 200 having the downward flange 203 has similar shape and equivalent outer peripheral edges to the face plate 100.
Rectangular-array-distributed projections 201 are on the upper surface of reinforcement plate 200, which adjoin to each other and have bonding surface to the inner surface of face plate 100 via ultrasonic bonding. There is no need to bond all projections 201 that is stagger distribution on the upper surface of reinforcement plate 200 to the inner surface of face plate 100, but to just fasten is ok. Pipes with quadrate cross section are bent to form the reinforcement frame 300 that is between face plate 100 and reinforcement plate 200. Every projection 201 corresponds to a concave pit 202 in the lower surface of the reinforcement plate 200.
Conjunction details of each part can be known according to FIG. 2. The reinforcement plate 200 bonds the face plate 100 closely through projection 201. The downward flange 203 of the reinforcement plate 200 mates the upward flange 101 of the face plate 100 vertically to form the outboard of the whole table top where the reinforcement frame 300 support the table top.

Embodiment 2

FIG. 3 shows an explored view and partly sectional view of the preferred embodiment 2 according to the invention; the basic inside structure of the composite table top 10 is similar to the preferred embodiment 1 such as the shape, distribution of projections and the way they combine. The difference is that the composite table top 10 is combined with two pieces through the hinge 11. The composite table top 10 can be fold facing the lower surface of the reinforcement plate 200 through the hinge 11.

Embodiment 3

FIG. 4 shows an explored view and partly sectional view of the preferred embodiment 3 according to the invention. The composite table top 10 still comprises a face plate 100 that has the same structure as the preferred embodiment 1 and 2, a reinforcement plate 200 and a reinforcement frame 300. The projections 201 of the reinforcement plate 200 are long strip and distributed as regular array with space to each other. The concave pit 202 sharing the same shape with the projection 201 is corresponded to the projection 201; the interface of the concave pit 202 which contacts with the inner surface of the face plate 100 is also long strip.
Conjunction details of each part can be known according to FIG. 5. Stagger distribution can also be chosen to fix the projection 201 of the reinforcement plate 200 on the inner surface of the face plate 100 through cementation. Frame with L-shaped cross section are bent to form reinforcement frame 300 which is fasten on the downside of the reinforcement plate 200 and the outside of the whole composite table top 10, and the reinforcement frame 300 is in the exterior of the reinforcement plate 200. The reinforcement frame 300 covers the upward flange 101 and downward flange 203 which are mate with each other from outside.

Embodiment 4

FIG. 6 shows a perspective view of the preferred embodiment 4 according to the invention. The composite table top 10 used in this the preferred embodiment is the same as the preferred embodiment 1. A portable folding scheme is formed by an erecting floor 13 that is located on the bottom of the composite table top 10 and used for fastening the folding legs 401.
