Abstract

Abstract A flat topped support useable as a table and as a seat is made of lumber. A top is made of a plurality of short boards side-byside and two spaced apart wood strips which extend across the undersides of the boards and is secured to all of them. The edges of the strips that face each other are undercut to form channels or recesses. Two or more pairs of crossed wooden legs support the top. A pivot bolt pivotally secures the legs of each pair together. Outside the legs at the top of the leg pairs a brace board connects the adjacent pairs and seat in the recesses. A locking bar is suspended from the top midway between the strips by a coiled spring and has its ends notched to provide seats for the lower edges of the brace boards. The spring is of such length that it is under tension when the notches of the bar seat on the lower edges of the brace boards. Lower brace boards may be used to hold the spacing between adjacent pairs.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 191 words
A flat topped support useful for outdoor furniture, comprising: a flat top piece made up of boards arranged side-by-side; two spaced apart parallel wood strips, one strip engaging the underside of the top piece near one of the ends of the boards and the other strip engaging the underside of the top piece near the other end of the boards; means securing each of the boards to both strips; a plurality of pairs of wooden legs crossing each other intermediate their ends; a pivot bolt passing through both legs of each pair where they cross each other and pivotally securing the legs of the pair together; an outside brace board fixed to each leg of one pair and extending from that leg of one pair to the corresponding leg of the next adjacent pair whereby to connect the pairs of legs together; the top edges of said brace boards seating against the facing edges of the strips and the top piece adjacent thereto; and a locking bar having notched ends engaging the lower edges of the brace boards and holding the top edges of the brace boards against the top piece.
