The upper end side of the member is provided with a fixing means consisting of a hook-shaped protruding claw that detachably fixes the upper end side of the member, and the upper substantially planar member, the central substantially planar member, and the lower substantially planar member are arranged in a substantially N-shape. and integrally fasten the upper end portions of the upper substantially planar member and the lower substantially planar member using the fixing means, while fitting the upper leg portions onto the center leg portions to form a backpack; A bed that can be used as a backpack, characterized in that the fixing means is removed and the three members are stretched out in a substantially straight line, and the upper legs are placed on the same side as the central legs to form a bed. be.

Embodiments Next, the present invention will be described in detail based on embodiments shown in the drawings.

The bed that can be used as a backpack according to the present invention includes:
It can be folded and used as a backpack, or unfolded and used as a bed. First, we will explain the case where it is unfolded and used as a bed, as shown in FIGS. 1 and 2.

The bed that can be used as a backpack according to the present invention includes:
It consists of an upper substantially planar member 20, a central substantially planar member 30, and a lower substantially planar member 40, which constitute three surfaces on which to lie down the body.

The upper substantially planar member 20 has a surface on which the upper part of the body is placed, which is made up of an outer frame 1 made of a pipe-shaped member, a beam 2 reinforcing the outer frame 1, and a cloth 3 as an intermediate material stretched over the outer frame 1. There is. Furthermore, in order to support this surface, the upper end of the outer frame 1 is provided with an L-shaped upper leg part 5 rotatably connected by a connecting part 4, while auxiliary legs are provided on both sides of the lower end of the outer frame 1. A portion 6 is provided protrudingly.

The central substantially planar member 30 includes an outer frame 7 made of a pipe-shaped member and a cloth 8 as an intermediate material, and has a surface on which the central part of the body is placed, and the outer frame 7 to support this surface. Central leg portions 9 are provided protruding from both sides of the lower end portion. At the upper end of the outer frame 7, the lower end of the outer frame 1 of the upper substantially planar member 20 is arranged on the outside of the outer frame 7, and both are connected to each other by the studs 11.
are rotatably connected. Therefore, the upper substantially planar member 20 and the central substantially planar member 30 can be rotated about the studs 11 and folded in half. Furthermore, a pair of left and right rings 10 for fastening shoulder straps 19 are attached to the lower end of the outer frame 7 on both sides.

The lower substantially planar member 40 has an outer frame 12 made of a pipe-like member and a surface on which a lower body part made of cloth 13 as an intermediate material is placed. It is rotatably attached to the inside of the unit. The lower leg portion 14 is provided with a bent portion 15 for hooking to prevent the shoulder strap 19 from slipping. Lower substantially planar member 40
At the upper end, the outer frame 12 of the lower substantially planar member is attached to a shaft rod 18 whose both ends are fixed to the lower end of the outer frame 7 of the central substantially planar member 30 located outside the outer frame 12. They are rotatably connected. Therefore, the central substantially planar member 30 and the lower substantially planar member 40 can be rotated about the axis rod 18 and folded in half. In addition, on the back side of the outer frame 12 of the lower substantially planar member 40, a cloth 17 for waist support is stretched for use as a backpack.

As shown in FIG. 1, the above three substantially planar members are rotated around the studs 11 and the shaft rod 18 and stretched into a substantially straight line, and the upper legs 5, the auxiliary legs 6, the central legs 9 and The lower legs 14 are arranged so as to protrude to the same side, and the three substantially planar members connected to each other can be used as one bed.

Next, a case will be described in which the bed that can be used as a backpack according to the present invention is used as a backpack.

First, as shown in FIGS. 3 to 4, three substantially planar members are rotated around the stud 11 and the shaft rod 18 and folded into a substantially N-shape, so that the three substantially planar members appear on one side. shall be. In order to fold the upper substantially planar member 20 into a substantially N-shape, first
It rotates in the direction of arrow A in the figure and folds the central substantially planar member 30 toward the central leg portion 9, and at the same time rotates the upper leg portion 5 in the direction shown by arrow B and folds it.
The upper legs 5 are fitted between the central legs 9 provided on the lower end side of the central substantially planar member 3 and rest on them, thereby forming one cargo platform.

Next, the lower substantially planar member 40 is rotated about the shaft rod 18 in the direction of the arrow C so that the central substantially planar member 3
At this time, the lower legs 14 are rotated in the direction shown by the arrow D to be stored in the same plane as the outer frame 12, while the hook-shaped parts provided at the upper end of the outer frame 12 as a fixing means are folded. The claws 16 protruding from the outer frame 1
2 and removably engages with the upper end of the outer frame 1 on the surface of the already folded upper substantially planar member 20 on which the upper part of the body is placed, thereby integrally integrating the outer frame 1 and the outer frame 12. You will have to hold it down so it doesn't move.

Further, one end thereof is always connected to the ring 10 described above.
The other ends of a pair of handle-shaped shoulder straps 19 for carrying as a backpack are attached between the lower end of the outer frame 1 and the upper end of the outer frame 7, which overlap each other. At this time, as described above, the lower leg part 14 is the upper part of the backpack (the lower substantially planar member 4
The shoulder strap 19 is passed between the bent portions 15 of the lower leg portion 14 described above, and the upper substantially planar member 20 is Outer frame 1 of beam 2 and lower substantially planar member 40
If you attach it through 2 and fix it between them, 3
The two substantially planar members are folded into a substantially N-shape, and the assembly as an integrally attached backpack is completed in a state where they apparently form one surface.

The user loads the baggage on the luggage platform made up of the above-mentioned upper legs 5 and central legs 9, and carries the bed as a backpack on his back using the shoulder straps 19 in the same way as a normal backpack. Also, at this time, the above-mentioned waist support cloth 17
Hachiyodo is designed to hit the lower back of the user.

Next, modified examples of the present invention shown in FIGS. 5 to 8 will be described. In the figures, the same members as those in the above-described embodiment are designated by the same numbers, and the description thereof will be omitted.

Similar to the above-described embodiment, this modification also has an upper substantially planar member 20, a central substantially planar member, and a lower substantially planar member 40, each of which is made of a cloth that constitutes an outer frame made of a pipe-shaped member and an intermediate material. Consisting of

In the central substantially planar member 3, the upper end of the outer frame 7 constitutes an auxiliary leg portion 6, and both left and right end portions 11 of the upper substantially planar member at the lower end of the outer frame 1 are rotatably attached. There is. Further, the grounding side of the central leg portion provided on the lower end side of the central substantially planar member 3 has a curved portion 9a on the upper end side.

When using the bed that can be used as a backpack in this modification as a bed, as in the above embodiment,
The three substantially planar portions may be substantially linear.

On the other hand, when using the backpack as a backpack, the respective members may be rotated in the directions of arrows A to D in the same manner as in the above embodiment. At this time, as shown in FIG. 8, when the upper leg part 5 is fitted between the central leg parts 9 to form a loading platform, the curved part 9a of the central leg part 9
is adapted to engage with the upper leg portion 5.
