部材。 The upper ends of a pair of left and right assembled legs with horizontal rods connected to both ends of the two front and rear support frame rods that support the table board with reinforcing rods placed horizontally on both ends are pivoted, and each of the assembled legs is moved inward. In a foldable long desk that can be folded freely,
An upper end portion of a first connecting member having a square cross section is pivotally attached to the reinforcing rod, a lower end portion of a second connecting member having a square cross section is pivotally attached to the horizontal rod of the assembled leg, and the second connecting member The upper end portion and the lower end portion of the first connecting member are pivotally supported and connected to each other so as to be bendable in one direction, and long notched windows are provided in the back portions of both connecting members to connect to each other, and the back side of the first connecting member A leaf spring that can intervene in the cutout window is fixed to the part so that the leaf spring is bent toward the back part, a cam piece is fixed to the back part of the second connecting member, and the leaf spring is attached to the tip of the cam piece. The trochanter that presses the leaf spring is provided with an arc-shaped bulge that supports the trochanter that presses the trochanter, and is spaced apart from the trochanter by a certain distance and also alternately presses the leaf spring, so that the trochanter that presses the leaf spring bulges during folding of the assembled leg. 1. A leg connecting member for a folding long desk, characterized in that the assembled legs can be temporarily stopped when switching between sections.
