Claims (1)

[Scope of Claim for Utility Model Registration] 1. The floor structure frame is divided into floor sections of appropriate area that can be folded in the longitudinal direction, and one divided floor section and the other adjacent floor section are both floor sections. The legs for supporting the floor structure frame are rotatably suspended from the other floor surface parts, and the tips of the connecting members are rotatably pivoted to the legs. and the connecting member extends from the other floor part side to the first floor part side so as to be substantially parallel to the longitudinal direction of the one floor part and the other floor part in the unfolded state. When the adjacent floor part is folded into one floor part, the legs are moved in the bending direction of the floor part by the connecting member in conjunction with the folding. The legs are folded in a relatively opposite direction, and when the floor section is unfolded, the folded legs appear in a usable state in conjunction with the unfolding operation. Simple foldable bed. 2 The floor structure frame is divided into five foldable floor sections in the longitudinal direction, and the left floor section and right floor section located on the left and right sides of the base section located in the center are wide. The left end floor surface section and the right end floor surface section are connected to each other in the same shape and parallel to each other so as to stand up approximately vertically around the adjacent portion of the base surface section. The floor portions are each rotatably connected via a connecting intermediary member so as to have a width smaller than the width of the left floor portion and the right floor portion, and rotate 180 degrees with respect to the left floor portion and the right floor portion, respectively; The legs for supporting the floor structure frame are fixedly provided at both ends of both edges of the base floor surface section, and are rotatable toward the left end floor surface section and the right end floor surface section of the left floor surface section and the right floor surface section, respectively. and further rotatably provided on the left end floor portion and the right end floor portion, and the legs provided on the left floor portion and the right floor portion, respectively, are connected to connecting members substantially parallel to the respective floor portions. Therefore, the connecting members are rotatably connected to the fixed legs closest to the base surface section, and the legs provided on the left end floor surface section and the right floor end surface section are substantially parallel to the respective floor surface sections. The left end floor portion and the right end floor portion are bent 180 degrees with respect to the corresponding left floor portion and right floor portion, respectively, and the left floor portion and When the right floor part is bent 90 degrees with respect to the base part, the legs of the left end floor part and the right end floor part, and the legs of the left floor part and right floor part are connected to their respective connecting members in conjunction with the folding movement. Therefore, the left and right floor parts are folded in a direction relatively opposite to the bending direction of the floor part, and the left and right floor parts stand up at right angles from both sides with the base part as the center, and the left and right floor parts stand up in parallel. In between, the left end floor part and the right end floor part are folded in parallel to form a rectangular parallelepiped shape, and conversely, from the folded state, the left end floor part and the right floor part, and further the left end floor part and the right end This simple folding bed is characterized in that when each floor part of the floor part is unfolded, each folded leg appears in a usable state in conjunction with the unfolding operation. 3. The floor structure frame is divided into at least seven floor sections that can be folded in the longitudinal direction, and the divided first floor section, third floor section, fifth floor section, and seventh floor section, as well as the following: As you go to the odd-numbered floor parts of
The second floor part, the fourth floor part, the sixth floor part, and furthermore, the floor parts of the following even-numbered orders are sequentially formed smaller than the previous floor part, and the adjacent floor parts are rotated with respect to each other. At least one of the first, second, and third floor surfaces is a base surface, fixed legs are vertically disposed on the base surface, and any other floor surface has a rotating base. A movable swinging leg is installed vertically, and each swinging leg connects the swinging leg of the floor section adjacent to the base surface section to the fixed leg of the base surface section, and the swinging leg of the floor section not adjacent to the base surface section. The swinging leg is rotatably connected to a floor part located on the side of the base part from the floor part through a connecting member extending substantially parallel to each floor part, and the floor parts are connected to each other. By sequentially folding the floor parts starting from the floor part in the lowest order, the corresponding swinging legs are rotated relative to the bending direction of the floor part by the respective connecting members in conjunction with these folding operations. At least the first, second, and third floor sections become the outermost shell, and the fourth and subsequent floor sections are folded into a substantially spiral shape. In addition, when each floor section is sequentially unfolded from the folded state, each folded swinging leg appears in a usable state in conjunction with the unfolding operation. A simple foldable bed featuring:
