    • A combined foldable table and bench unit embodies a pair of elongated seats arranged in parallel, spaced relation to each other. Transverse, vertically extending frame supports mounted adjacent the ends of each seat support the seats above a supporting surface. An arm is pivotally connected at one end thereof to an upper front portion of each frame support. The arms are adapted for pivotal movement selectively to a rearwardly extending horizontal position and to a vertical position. A back support member extends between and is carried by the other ends of the arms of each elongated seat. When the arms extend rearwardly and horizontally, the back support members carried thereby extend vertically and define facing benches. When the arms are pivoted to their vertical positions, the back support members are pivoted to a horizontal position with adjacent portions thereof in abutting relation with each other to define a table at an elevation above the seats. A releasable connector member carried by each back support member detachably connects the adjacent portions of the back support members to each other.
    • 组合的可折叠台和台单元体现了一对彼此间隔开的平行布置的细长座。 靠近每个座位的端部安装的横向,垂直延伸的框架支撑件支撑在支撑表面上方的座椅。 臂在其一端枢转地连接到每个框架支撑件的上前部。 臂适于枢转运动选择性地向后延伸的水平位置和垂直位置。 后支撑构件在每个细长座的臂的另一端之间延伸并由其承载。 当臂向后和水平延伸时,由此承载的背部支撑构件垂直地延伸并限定相对的长凳。 当臂枢转到其垂直位置时,后支撑构件枢转到水平位置,其相邻部分彼此邻接,以在座椅上方的高度处限定桌子。 由每个后支撑构件承载的可释放的连接器构件将后支撑构件的相邻部分彼此可拆卸地连接。
