  • Patent number: 4686910
    Abstract: A work table is disclosed having three end-to-end abutted sections joined by adjustable longitudinal bars for forming a rigid table from one or more of the respective sections. Four sets of adjustable bars extend longitudinally of the table and fit varying lengths of the table comprising from 1 to 3 sections of the abutted table members. The bars extend in parallel to the longitudinal length of the table, provide rigidity to the respective table sections as well as extend between the respective sections when one or more leaves are joined. Cross X-type legs are provided with a variable pivot. The variable pivots enables the crossover point of the legs to be varied so that the table may be disposed at various heights and inclinations about its longitudinal length. The legs are provided at their upper end with U-sectioned channels having locking wing nuts for keying at selected locations to the longitudinal bars.
