A system for injection molding a half-section of a collapsible table that includes a pair of interhinged half-sections. The system is provided with a mold whose dimensions are appropriate to the half-section to be molded therein, and a driven carrier adjacent one end of the mold having cautilevered therefrom parallel core rods that project into the mold. When the carrier is driven to cause the core rods to occupy an “in” position in which the rods are fully within the mold and extend the full length thereof, molten plastic is then injected into the mold to submerge the rods therein. When the plastic cures and rigidifies, parallel reinforcing beams are then created about the rods which are integrated with the resultant half-section. When the carder is driven to withdraw the rods from the mold which are now in an “out” position, the reinforcing beams are then hollow and the resistance of the half-section to bending forces is enhanced.
A system for injection molding a half-section of a collapsible table having a pair of interhinged half-sections supported on leg assemblies, tie half-section, being reinforced by hollow parallel beams integral therewith, said system comprising:

1. Field of the Invention
This invention relates generally to a collapsible table having a pair of interhinged half-sections, and more particularly to a system for injection molding a reinforced half-section for a collapsible table.
2. Status of Prior Art
For a better understanding of the invention as well as other objects and further features thereof, reference is now made to the annexed drawings wherein:
FIG. 1 is a perspective view of a collapsible table in accordance with the invention in its erected state composed of an interhinged pair of half-sections;
FIG. 2 shows the underside of the tabletop;
The Collapsible Table: Referring now to FIGS. 1 to 3 shown in these figures in a collapsible table in accordance with the invention whose half-sections are reinforced by hollow beams to render the table capable of supporting heavy loads without being deformed hereby as when a banquet table is overloaded with pots and plates containing foods a centerpiece and various other more or less heavy items. The resultant deformation of the tabletop may cause the load to shift and slide off the table. Hence an important aspect of a collapsible tabletop in accordance with the invention is that despite the fact that it is formed of a relatively light weight plastic structure, it is nevertheless capable of sustaining a heavy load without deformation.
It is to be understood however, that the invention is not limited to a banquet table, for a similar but smaller version of the collapsible table may be used as a worktable or for other purposes; retaining the advantage that when the table is in its collapsible state, the resultant compact structure requires little storage space.
The tabletop of the collapsible table shown in FIG. 1 is composed of a pair of like half-sections 10 and 11 whose adjacent ends are interhinged by a hinge 12. In the operative state of the table, the half-sections are coplanar to create a horizontal table surface. Hinged to the underside of half-section 10 is a leg assembly 13, while hinged to he underside of half-section 11 is a leg assembly 14. In the operative or erect state, the leg assemblies are unfolded to support the tabletop. In the collapsed state, the legs are folded in against the half-sections ad the half-sections are then folded together.
