DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

1. Configuration of Frame Structure

With reference toFIG.1, the configuration of a frame structure1of the present embodiment will be described. A1ofFIG.1is a front view of the frame structure1and A2is a right side view of the frame structure1.

The frame structure1includes a framework10that is formed by connecting a plurality of outline frames11by means of a joint12and that defines a space S capable of accommodating a user U, a sheet20(a floor surface sheet20a, a side surface sheet20b, and a top surface sheet20c) that is stretched over the framework10so as to form a floor surface, a side surface, and a top surface of the space S, and a support frame13that supports a floor surface F formed by the floor surface sheet20aat a position higher, by only h, than a base surface G (outdoor ground, indoor floor surface, or the like) where the frame structure1is placed. Note that the floor surface sheet20a, the side surface sheet20b, and the top surface sheet20cmay be one continuous sheet.

Further, the frame structure1includes battery attachment portions31a,31bfor attaching a battery30to an under surface side of the floor surface F, an outlet32provided on the side surface sheet20b, a battery cable33(corresponding to the battery connecting portion of the present disclosure) for connecting the battery30and the outlet32, and an air cushion40placed on the floor surface F. The battery attachment portions31a,31bsecurely attach the battery30to outline frames11a,11bof the floor surface F. In this manner, as compared to a case in which the battery30is attached to the floor surface sheet20a, the battery30can be stably attached.

The outlet32is provided with a socket for supplying an AC power with the same specification as that of a commercial power supply and a USB (Universal Serial Bus; Registered Trademark) port. The battery30includes a battery and an inverter that converts a DC power output from the battery into the AC power with the same specification as that of the commercial power supply and supplies, to the outlet32, the DC power for the USB port and the AC power for the socket.

The air cushion40is inflated by air injection, and its outer periphery when the air cushion is inflated becomes larger than an outer periphery of the floor surface F. In this manner, when the user U sits on the air cushion40, the weight load of the user U is dispersed to the outer side of the floor surface F by the air cushion, so that the battery30can be prevented from contacting the base surface G due to lowering of the floor surface F.

The battery30is provided with an external battery connecting portion34for connecting an output terminal of the battery30to an external battery. InFIG.1, as the external battery, a battery30′ attached to another frame structure1′ is illustrated.

In this case, when a residual amount of the battery30′ is reduced, a user of the other frame structure1′ connects the battery30′ to the external battery connecting portion34of the battery30by means of an external connection cable35, so that the power supplied from the battery30can be used. Therefore, the user of the other frame structure1′ can continue using a home electric appliance in the other frame structure1′ without replacing the battery30′ with a small residual amount.

As illustrated in a balloon W, a front surface sheet21can be attached to a front side of the frame structure1by means of a fastener22. Further, an upper portion of the side surface sheet20bis provided with a ventilation portion24made of a mesh fabric or the like.

2. Aspect of Attaching Floor Surface Sheet to Outline Frame

With reference toFIG.2, an aspect of attaching the floor surface sheet20ato an outline frame11cfor the floor surface will be described. As illustrated in B1, the floor surface sheet20ais provided with a sleeve25, and first, the user U passes the outline frame11cthrough the sleeve25so as to roughly position the floor surface sheet20ain an X-direction and a Y-direction.

Next, the user U holds an end of the floor surface sheet20aby his/her hand H, and folds the floor surface sheet20atoward its under surface side along the outline frame11cwhile applying tension to the floor surface sheet20aby pulling it toward himself/herself as indicated by an arrow t. Then, as illustrated in B2, the user U couples hook and loop fasteners26(Velcro (Registered Trademark), MAGICTAPE (Registered Trademark), or the like) provided on an under surface of the floor surface sheet20ato fix the floor surface sheet20ato the outline frame11c.

In this case, since the floor surface sheet20ais stretched over the outline frame11cin different stretching ways in the X-direction and the Y-direction, the tension of the floor surface F formed by the floor surface sheet20aillustrated in B2is strengthened. Therefore, the stiffness of the assembly-type frame structure1can be maintained high.

3. Procedure of Dismantling Frame Structure

With reference toFIG.3, a procedure in dismantling the frame structure1upon finishing the use of the frame structure1will be described. As illustrated in C1, first, the user U disconnects the battery cable33from the outlet32and removes the battery30from the battery attachment portions31a,31b(seeFIG.1). Then, the user U disconnects an upper portion1afrom the joint12that connects the upper portion1aand a lower portion1bof the frame structure1to separate the upper portion1aand the lower portion1b.

Next, as illustrated in C2, the user U disconnects the sheet20from the outline frame11and houses the folded sheet20in a housing bag60. Further, the user U takes out the air cushion40and releases the air therefrom and houses the folded air cushion40in a housing bag61.

Next, as illustrated in C3, the user U disconnects the outline frame11and the support frame13from the joint12and puts them together in a single unit form. Then, the user U puts together and houses, in one housing bag70, the housing bag60that houses the sheet20, the housing bag61that houses the air cushion40, the outline frame11, the joint12, and the support frame13that are put together as a single unit form, the battery30, and the battery cable33.

In this manner, the user U can easily disassemble and dismantle the frame structure1. Then, the user U easily carries one housing bag70and assembles the frame structure in a favorite place so that a personal space can be secured.

4. Another Embodiment

In the aforementioned embodiment, the weight load of the user U exerted on the floor surface F with the floor surface sheet20ais dispersed by including the air cushion40, but when the weight load resistance of the floor surface F with the floor surface sheet20ais sufficient, the air cushion40may be omitted.

In the aforementioned embodiment, the battery attachment portions31a,31bfor attaching the battery30to the outline frame11are illustrated, but the configuration may be made such that the battery30is attached to the under surface of the floor surface sheet20a. In this case, for example, a battery attachment portion in a pocket shape that houses the battery30may be provided on the under surface of the floor surface sheet20a.

In the aforementioned embodiment, the external battery connecting portion34for connecting the battery30to the external battery30′ is provided, but the configuration may be made so as to omit the external battery connecting portion34.

Note thatFIG.1is a schematic view illustrating the functional configuration of the frame structure1segmented in accordance with the major processing contents for facilitating understanding of the invention of the present disclosure, and the functional configuration of the frame structure1may be based on other segments.
