With the sections ll, [2, l3 and I4 folded to nested positions on the table top, the head 3|.

of the pin is positioned in recesses 33 in the corners of the extending sections and the pins l1 and I8 extend into the annular groove 22 of the pin [6, as shown in Figure 4. The pin I6, therefore, provides means for locking the extending sections in the folded position and with the head 3| of the pin in the recesses 33 the upper surface of the head of the pin is flush with corresponding surfaces of the sections.

The latch pins i1 and 18 are provided with enlarged sections 34 and 35 that are slidably mounted in the tubes 19 and 20, respectively and with the parts positioned as shown in Figure 3 the pins 11 and I8 extend through openings in the ends of the tubes.

The pins are retained in these positions by the springs 23 and 24 and tension on the springs is adjusted by plugs 38 and 31 threaded in the ends of the tubes. The tubes 19 and 20 are secured to the under surface of the table top by screws 36. v

The table top may be provided with legs as indicated by the dotted line 38 or the top may be supported by other suitable means.

With the parts as illustrated in Figure 6 the expanding sections 1 2 and 13 are partly folded upon the table top or panel l0 and the latching pin 16 is shown in an upwardly extended position before it is drawn downwardly into the locking position shown in Figures 3 and 4.
