- the supporting structure described herein is completely self supporting and operative in and of itself, and does not require the table top sections 47 to hold the parts .thereof together in operative relation. Therefore, a table top section 47 may be easily replaced if damaged.
- Mechanism for locking the assembly in the closed position, comprising a latch 51 and an arm 52 (FIGS. l, 5 and 6).
- the latch 51 is pivotally connected .to the pin 32 which connects one of the aprons 31 to a member 12 of an end leg support, and the arm 52 is secured to the latch 51 and engages the adjacent member 12.
- the arm 52 holds the latch 51 in substantially horizontal position during opening and closing movements of the assembly, and in position for a hook formed on the latch 51 to engage .the pin 32 at the opposite end and on the same side of the assembly when the assembly is in its closed position (FIGS. 4 and 6). To this end, the pin 32 which is engaged, extends outwardly a short distance from the side of the assembly.

- a circular hole 67 is formed at the center of the washer 63, which is large enough to receive the rod 56. As clearly shown in FIGS. 9 and 10, the hole 67 is countersunk from both sides of the washer 63.
- the washer 63 is positioned within the catch housing 61 so that it is below the upper end of the rod 56 when the table is open, and the washer may be pivoted between a position where the axis of the lhole 67 is substantially coincident with the axis of the rod 56 and the housing 61, and a position where the axis of the hole 67 is noncoincident with the other two laxes.
- the rod 56 may be inserted into the hole 67 and moved freely of the washer 63 therein, and when they are substantially noncoincident, the margin of the hole 67 engages and holds the rod 56 against movement.
- the upper end of the rod 56 is sharpened or beveled somewhat so that it is self guiding into the hole 67, and also into the ⁇ openings 59 of the upper cross brace 26, as the assembly is opened.
- a biasing means in the form of a coiled compression spring 68 (FIG. 8) is provided which urges .the portion of the washer 63 within the housing 61 downwardly, or counterclockwise, and, consequently, the hole 67 into a non coaxial relation with the rod 56.
- the spring 68 is positioned between the upper side of the washer 63 and a pin 69 which is secured in the catch housing 61.
- the spring 68 urges the washer 63 in the countercloclcwise direction, as shown in FIG. 8, and causes the margin of the hole 67 to tightly engage the rod 56 and prevent downward movement of the rod 56.
- a release in the form of an L-shaped hand lever 71 is provided.
- the lever 71 is pivotally fastened to the outside of the catch housing 61 by means of a pin 72 and two ears 73 which are secured in spaced apart relation to .the outside of the catch housing 61.
- a hole is formed through the lever 71 generally at its bend, and a pin 72 is rotatably mounted in this Ihole and is secured to the ears 73.
- the lower relatively short arm of the lever 71 extends through an opening 74 formed in the catch housing 61 between the ears 73, and the end of this arm of the lever 71 extends underneath the washer 63.
- the end of the lever 71 within the catch housing 61 is rounded ott so that it will slide easily on the undersurface of the washer 63.
- the ears 73 and the opening 74 are on the opposite side of the housing 61 from the opening 66 for the tab portion 64 of the washer 63, and the end of the lever 71 within the housing is adjacent the end of the washer 63 opposite the tab portion 64.
- the lever 71 extends upwardly into the space 45 between the table top sections 47, and its upper end is below the upper surface of the top sections 47 so that it cannot interfere with the use of the table. Further, the lever 71 is made from flat stock and it is twisted through an ⁇ angle of 90 adjacent its upper end as shown in FIGS.
- the rod S6 and the catch mechanism includ-ing the hand lever 71 are preferably mounted at substantially the longitudinal center line of the assembly so that the upper end of the lever 71 may be reached with equal ease from either side of the assembly.
- the hand lever 71 may be released, and a torsion spring 76 (FIG. 8) returns the lever 71 to its original position before it was manually pivoted.
- the torsion spring 76 is wound around the pin 72 ⁇ and its ends engage the lever 71 and the catch housing 61 such as to pivot the lever 71 in the clockwise direction as seen in FIG. 8.
- the lower edge of the lever 71 engages the lower edge of the opening 74 in the housing 61, which engagement limits the amount of clockwise pivotal movement of the lever 71.
- a novel and useful open position locking mechanism for a folding table assembly has been provided.
- the mechanism automatically engages when the assembly is moved to its open position and it may be easily disengaged from either side of the assembly for movement to its closed position. Further, the mechanism is in an out-of-the-way posit-ion where it cannot interfere with persons using the assembly and where it cannot become accidentally disengaged.
