[Prior art]

 FIG. 7 shows a conventional folding bed 1 disclosed in JP-A-7-246132. In the folding bed 1, a pair of support rods 12 are provided on both left and right ends of a pair of leg frames 11 arranged at both ends in the longitudinal direction so as to be parallel to each other. A sheet member 13 is stretched between the support rods 12 so that the seat member 13 can be laid down or seated upon being unfolded. A pair of pivot pieces 111 of each leg frame 11 are pivotally connected to both ends of the support rod 12 by pivot pins 112. A long leg member 113 is connected to the lower end of one pivot piece 111 of each leg frame 11. A pair of connecting pieces 115 are pivotally supported by a pivot shaft 114 on the long leg member 113 so as to sandwich the central portion in the longitudinal direction from the inner side surface and the outer side surface. The lower end of the upper short leg member 116 is connected to one end of the connecting piece 115, and the upper end side of the upper short leg member 116 is connected to the pivot piece 111. Further, the upper end of the lower short leg frame 117 is connected to the other end of the connecting piece 115 so as to extend obliquely with respect to the ground. In this way, both ends of the pair of support rods 12 are supported by the upper ends of the long leg member 113 and the upper short leg member 116.

When the folding bed 1 is folded, as shown by an arrow A in FIG. 7, the connecting piece 115 is rotated about the pivot shaft 114 as a fulcrum, and the upper short piece connected to both ends of the connecting piece 115 is rotated. The leg member 116 and the lower short leg member 117 are simultaneously aligned in parallel with the long leg member 113. After that, as shown by an arrow B in FIG. 7, the pair of pivot pieces 111 and the entire leg frame 11 are upwardly moved about 270 about the circumference of the tip of the support rod 12 with the pivot pin 112 as a fulcrum. The leg frame 11 is folded on the supporting rod 12 as shown in FIG. By folding in this manner, the volume of the folding bed 1 can be reduced.

[Problems to be solved by the device]

 However, in the folded state shown in FIG. 8, the upper short leg member 116 and the lower short leg member 117 are arranged parallel to each other on both sides of the long leg member 13. Therefore, the long leg member 113 and the upper short leg member 116 are superposed in parallel on the support rod 12, but the lower short leg member 117 protrudes laterally from above the support rod 12. That is, the width of the folded leg frame 11 is larger than the width of the pair of support rods 12 aligned in parallel, and in this respect, the conventional folding bed 1 has an ideally reduced volume in the folded state. Didn't.

The present invention has been made in order to solve the above problems in the conventional folding bed, and an object thereof is to provide a folding bed which is more convenient to carry and store by further reducing the width in the folded state. It was made as.

There is a point.

Both ends of the pair of support rods 3 are supported by the pair of leg frames 2 and are laid horizontally. Each support rod 3 includes a pivot seat 31 and a pair of rod bodies 32. The pivot seat 3 includes a pair of fitting members 311. These fitting members 311 are pivotally connected to each other by a sluice portion 312. Each fitting member 311 is provided with a fitting hole 313 extending in the axial direction. The rod 32 has a straight rod shape, and has one end as a coupling end 321 connected to the leg frame 2 and the other end as a fitting contact end 322 connected to a fitting hole 313 connected to the pivot seat 31. . The coupling end 321 is pivotally supported by the pivot pin 33 between the pivot contact walls 241 and 281. On the other hand, the fitting end 322 is inserted into the fitting hole 322 of the pivot seat 31 and fixed by the shaft pin 34.

Next, a method for assembling the folding bed of this embodiment will be described. First, the inner and outer connecting pieces 21, 22 are pivotally connected by the pivot shaft 20 inserted into the pivot holes 212, 222. In addition, the upper leg members 23, 26 are connected to the upper connecting portions 213, 223 of the inner and outer connecting pieces 21, 22 and the lower connecting portions 214, 224 of the inner and outer connecting pieces 21, 22 are connected to the lower connecting portions 214, 224. The side leg members 25 and 27 are connected. Further, leg pads 251 and 271 are attached to the lower leg members 25 and 27, respectively. Furthermore, the leg pieces 2 are completed by connecting the pivoting pieces 24 and 28 to the upper ends of the pair of upper leg members 23 and 26, respectively.

On the other hand, the fitting ends 322 of the pair of rod bodies 32 are respectively inserted into the fitting holes 313 of the pivot seat 31 and fixed by the shaft pins 34 to form two straight rod-shaped support rods. After that, the pair of support rods 3 are penetrated into the through holes 42 provided on both side edges of the sheet member 4, respectively, and the pair of coupling ends 32 of each support rod 3 are projected from the through holes 42, respectively. Next, each connecting end 321 is pivotally attached to the pivoting walls 241, 281 provided on the corresponding pivoting pieces 24, 28 of the leg frame 2 by the pivot pin 33, respectively, to assemble the support frame 3 and the seat member 4.

In the assembled state, the contact surface 220 of the outer connecting piece 23 contacts the contact surface 219 of the inner connecting piece 21, and the contact surface 210 of the inner connecting piece 21 contacts the outer connecting piece 23. It is in contact with the contact surface 229. Therefore, the four upper and lower leg members 23, 25, 26, 27 are in an intersecting state, and the pair of support rods 3 have both ends by the erection surfaces 242, 282 of the leg frame 2 provided on the pivoting pieces 24, 28, respectively. It is supported. Therefore, the sheet member 4 is maintained in a tightly stretched state.

When folding the folding bed of the present embodiment, as shown by the arrow C in FIG. 1, the pair of support rods 3 are brought close to each other, and the upper leg members 23, 26 connected to the support rods 3 are connected. Bring them closer to each other. At the same time, the inner and outer connecting pieces 21, 22 rotate about the pivot 20 as a fulcrum, and the lower leg members 25, 27 approach each other. Therefore, when the support rods 3 are aligned in parallel, the upper leg members 23, 26 and the lower leg members 25, 27 are also aligned in parallel with each other. In this state, the upper and lower leg members 23, 25 connected to the inner connecting piece 21 are arranged on the same straight line as the support rod 3. Similarly, the upper and lower leg members 26, 27 connected to the outer connecting piece 22 are also arranged on the same straight line as the supporting rod 3.

Next, as shown by an arrow D in FIG. 3, each leg frame 2 is rotated upward by 270 degrees about the shaft support pin 33 as a fulcrum, and each leg frame 2 is moved as shown in FIG. The support rods 3 thus aligned are stacked in parallel with each other. In this state, as shown in FIG. 4, the width of the pair of support frames 3 and the width of each leg frame 2 are substantially the same. As described above, the folding bed according to the present embodiment can reduce the width of the bed when folding, as compared with the case of the conventional folding bed shown in FIG.

Further, as shown by an arrow E in FIG. 4, each supporting rod 3 is folded in two stages with the sluice 312 as a fulcrum, and as shown in FIG. 5, each leg frame 2 and the rod body 32 are parallel to each other. Overlap. Therefore, the folding bed of the present embodiment has a reduced length as well as a width when folded.

In the folding bed according to the present embodiment, the flexible seat member 4 can be assembled so that the seat can be laid down or seated. Further, at the time of folding, since the supporting rod 3 is folded in two stages and the length is halved as described above, the volume at the time of folding can be sufficiently reduced as compared with the conventional bed of this type.

The present invention is not limited to the above embodiment, but various modifications can be made. For example, in order to prevent the support frame 3 and the leg frame 2 from expanding and expanding in volume after folding, velcro is sewn to the sheet member 4 and the folded support frame 3 and the leg frame 2 are bundled. You may do it. Further, if a shoulder belt is attached so that the seat member 4 can be carried on the back, it is more convenient to carry.

Further, as shown in FIG. 6, the support rod 52 laid between the pair of leg frames 51 is a single rod-shaped member having no pivotal contact portion, and the seat member 6 is made of a hard plate-shaped member. You can do it. The sheet member 6 has a flat mounting surface 61 on which an article can be mounted, and a fastening member for extending downward from the peripheral edge of the mounting surface 61 in the vertical direction and fitted on the pair of support rods 52. A rim 62 is provided. The seat member 6 may be fixed to the support rod 52 by a tightening band provided on the bottom surface of the seat member 6. In the case of the configuration of FIG. 6, since the support rod 52 is one rod-shaped body and the sheet member 6 is a hard plate-shaped body, it can be fixed in one form of a folding bed. . Further, by appropriately setting the lengths of the leg frame 51 and the support rod 52, it can be used as a table, a flower bed, an ornament shelf, or the like.

[0023]

[Effect of the invention]

 As is apparent from the above description, the folding bed according to the present invention has a structure in which a pair of leg frames that support a pair of support rods are structurally modified so that when folding, the upper and lower legs form a leg frame. Since the members can be aligned in parallel, the width of each leg frame when folded can be made equal to the width of the support rods aligned in parallel. Therefore, the folding bed of the present invention has a smaller width when folded than the conventional folding bed, and is convenient for form and storage. Further, in the case where each support rod has a structure in which a pair of rod bodies are connected by a pivotal seat having a sluice, the support rods may be folded in half as needed. In this case, the length when folded is short, which is more convenient for carrying and storing.
