[0016] An air sofa 10 according to one embodiment of the present invention is a sofa having a part that inflates and deflates by the inflow and outflow of air, and can be used as a baby sofa for seating a baby. In the following description, the user will be described as a baby.

[0017] As shown in Figure 1, the air sofa 10 according to this embodiment comprises a seat portion 11, a hollow peripheral wall portion 12 that expands and contracts with the intake and exhaust of air, and an anti-tipping portion 13 that protrudes outward from the outer surface of the peripheral wall portion 12. Furthermore, the air sofa 10 of this embodiment comprises a check valve 14 (see Figure 5), which will be described later, positioned between the peripheral wall portion 12 and the anti-tipping portion 13, and a discharge portion 15 that can discharge air from inside the air sofa 10. Note that the air sofa 10 may also have other components in addition to the seat portion 11, peripheral wall portion 12, anti-tipping portion 13, check valve 14, and discharge portion 15.

[0018] As shown in Figures 1, 4, and 5, the seat portion 11 is the part that supports the baby's buttocks and is formed in a sheet-like shape that intersects the vertical direction and has cushioning properties. In this embodiment, the seat portion 11 is formed in a hollow shape that expands and contracts by the intake and exhaust of air, similar to the peripheral wall portion 12 which will be described later. The seat portion 11 partitions the internal space 16 (hereinafter referred to as the "seat portion internal space 16"). The seat portion internal space (third space) 16 communicates with the peripheral wall portion internal space 17, which is the internal space of the peripheral wall portion 12 and will be described later. In this embodiment, the seat portion 11 is formed in a hollow shape that expands and contracts by the intake and exhaust of air, but it is not limited to this, and for example, it may be a sheet-like member that is soft enough to fold and on which a baby can be seated.

[0019] As shown in FIGS. 1 and 2, the peripheral wall portion 12 is a portion that supports the baby seated on the seating surface portion 11 from a direction intersecting the vertical direction, and stands up from around the seating surface portion 11. The peripheral wall portion 12 is preferably formed of a fabric subjected to flocking treatment in order to achieve a fluffy touch. As shown in FIG. 1, the peripheral wall portion 12 of the present embodiment is provided in an O shape in plan view so as to surround the entire area around the seating surface portion 11, and stands up with the front region (predetermined location) 12a being low. That is, the peripheral wall portion 12 of the present embodiment supports the baby seated on the seating surface portion 11 from the front-rear direction (direction intersecting the vertical direction) and the left-right direction (direction intersecting the vertical direction).

[0020] The peripheral wall portion 12 of the present embodiment integrally has a front region 12a that can support the baby's legs from below, a rear region 12b that can support the baby's back from behind, and left and right side regions 12c, 12d that support the baby from the left and right. The front region 12a is formed at the lowest height among the peripheral wall portion 12, and the rear region 12b is formed at the highest height among the peripheral wall portion 12. The left and right side regions 12c, 12d are continuous from both left and right ends of the rear region 12b, and gradually decrease in height toward the front and are continuous with both left and right ends of the front region 12a. That is, the air sofa 10 of the present embodiment is formed in a bowl shape with a concave central portion, and partitions a seating space ²¹ where the baby sits in the center. The seating space 21 is partitioned such that the lower part is the seating surface portion 11, the front is the front region 12a of the peripheral wall portion 12, the rear is the rear region 12b of the peripheral wall portion 12, the left and right are the left and right side regions 12c, 12d of the peripheral wall portion 12, respectively, and the upper part is open. The internal spaces of the front region 12a, the left and right side regions 12c, 12d, and the rear region 12b communicate with each other and constitute an internal space 17 in the peripheral wall portion described later.

[0021] In the present embodiment, the peripheral wall portion 12 is provided in an O shape in plan view, but is not limited thereto. For example, it may be a peripheral wall portion that is provided in a C shape in plan view with a part (front) around the seating surface portion 11 being open and stands up. Specifically, the peripheral wall portion may have a C shape in plan view in which the front ends of the left and right side regions 12c, 12d are blocked without having the front region 12a of the above-described O-shaped peripheral wall portion 12 in plan view.

[0022] As shown in FIGS. 3 and 5, the peripheral wall portion 12 partitions an internal space 17 (hereinafter referred to as the "internal space 17 of the peripheral wall portion"). As described above, the internal space 17 of the peripheral wall portion (the first space) communicates with the internal space 16 of the seating surface portion. In this embodiment, the internal space 17 of the peripheral wall portion and the internal space 16 of the seating surface portion are communicated, but the present invention is not limited to this, and the two spaces may not communicate with each other. In this case, a mechanism for injecting air into both the internal space 17 of the peripheral wall portion and the internal space 16 of the seating surface portion, and a mechanism for discharging air may be provided.

[0023] As shown in FIGS. 3 and 5, the anti-tipping portion 13 is a portion for preventing the air sofa 10 from tipping over, and protrudes outward from the outer surface of the peripheral wall portion 12 and is disposed at a position close to or in contact with a predetermined placement surface A on which it is placed during use. As shown in FIGS. 3 and 5, the anti-tipping portion 13 of the present embodiment protrudes rearward from the rear surface of the rear region 12b of the peripheral wall portion 12. That is, the anti-tipping portion 13 of the present embodiment is provided on the side opposite to the front region 12a of the peripheral wall portion 12 having an O shape in plan view. Further, when the peripheral wall portion 12 is formed in a C shape in plan view as described above, the anti-tipping portion 13 is provided on the side opposite to the opened side of the C shape in plan view. Thereby, the backward tipping of the air sofa 10 can be suppressed.

[0024] In this embodiment, one anti-tipping portion 13 protruding rearward from the rear surface of the rear region 12b of the peripheral wall portion 12 is provided, but the present invention is not limited to this, and a plurality of anti-tipping portions 13 may be provided. In this case, for example, in addition to one anti-tipping portion 13 protruding rearward from the rear surface of the rear region 12b of the peripheral wall portion 12, anti-tipping portions protruding outward from the outer surfaces in the width direction of the left and right side regions 12c and 12d may be provided. Thereby, the tipping of the air sofa 10 not only to the rear but also to both the left and right sides can be suppressed.

[0025] The anti-tipping section 13 of this embodiment functions as a pump capable of introducing air into the internal space 17 of the peripheral wall section. The anti-tipping section 13 is formed in a hollow shape that partitions the internal space 18 (hereinafter referred to as the "pump internal space 18"). The pump internal space (second space) 18 has a portion that communicates with the internal space 17 of the peripheral wall section, and a check valve 14 is provided in this portion. That is, a check valve 14 is provided between the internal space 17 of the peripheral wall section 12 and the pump internal space 18 of the anti-tipping section 13. The check valve 14 restricts the outflow of air from the internal space 17 of the peripheral wall section to the pump internal space 18, and allows the inflow of air from the pump internal space 18 to the internal space 17 of the peripheral wall section.

[0026] The anti-tipping section 13 of this embodiment is formed by a cylindrical section 13a that extends continuously to the rear from the rear surface of the rear region 12b of the peripheral wall section 12, and a rear surface section 13b that closes the rear end of the cylindrical section 13a. The anti-tipping section 13 has an opening 19 that connects the internal space 18 of the pump with the external space, and a lid section 20 that can close the opening 19. The opening 19 and the lid section 20 of this embodiment are provided in the central part of the rear surface section 13b of the anti-tipping section 13.

[0027] When using the anti-tipping section 13 as a pump to inflate the space 17 inside the peripheral wall, the opening 19 is covered with the lid 20 or the palm of the hand, and the anti-tipping section 13 is contracted. When the anti-tipping section 13 is contracted in this way, air is injected from the pump's internal space 18 into the space 17 inside the peripheral wall via the check valve 14. Next, with the opening 19 open, the contracted anti-tipping section 13 is pulled to inflate it. This allows air to enter the pump's internal space 18 while restricting the outflow of air from the space 17 inside the peripheral wall by the check valve 14. Then, with the opening 19 covered, the anti-tipping section 13 is contracted again. By repeating this process, the anti-tipping section 13 can function as a pump to inflate the air sofa 10.

[0028] The anti-tipping section 13 is preferably molded from a material such as synthetic resin that is harder than the peripheral wall section 12 and can be shrunk by hand. Furthermore, the anti-tipping section 13 is preferably molded from a material that easily returns to its original state (unshrunk state) after being shrunk. Examples of materials for the anti-tipping section 13 include PVC (Polyvinyl Chloride) fabric.

[0029] The discharge section 15 can be set to an open state that allows air to be discharged from the space 17 inside the peripheral wall, or to a closed state that restricts the outflow of air from the space 17 inside the peripheral wall. In this embodiment, the discharge section 15 may be, for example, an air valve in which, when the lid (not shown) is opened and the base is pinched, an internal valve (not shown) opens and the internal air is pushed out by high pressure.

[0030] In the air sofa 10 configured as described above, an anti-tipping part 13 is provided that protrudes outward from the outer surface of the peripheral wall portion 12 and is positioned to be close to or in contact with a predetermined mounting surface A on which the sofa is placed during use. Therefore, when weight is applied to the side of the anti-tipping part 13 (towards the rear in this embodiment), the anti-tipping part 13 can support the weight, thereby preventing the sofa itself from tipping over.

[0031] Thus, according to this embodiment, it is possible to provide an air sofa 10 that can prevent the sofa itself from tipping over.

[0032] Furthermore, since the anti-tipping unit 13 functions as a pump capable of introducing air into the internal space 17 of the peripheral wall, the number of parts can be reduced compared to the case where the anti-tipping unit 13 and the pump are provided separately. In addition, since the pump can be positioned on the rear side where it is not easily visible from the front, the appearance is improved compared to, for example, when the pump is provided on the upper surface of the peripheral wall 12.

[0033] Furthermore, by providing multiple anti-tipping sections 13, it is possible to suppress the sofa itself from tipping over in multiple directions.

[0034] Furthermore, by providing the anti-tipping section 13 on the rear side of the peripheral wall section 12 when it is O-shaped in plan view, or on the side opposite to the open side when it is C-shaped in plan view, the rear side, where weight is easily applied during use, can be supported by the anti-tipping section 13, thereby effectively suppressing tipping backward.

[0035] Furthermore, by forming the seat portion 11 in a hollow shape that expands and contracts by the intake and exhaust of air, both contractility and cushioning can be ensured. In this case, by creating a structure in which the inner space 16 of the seat portion communicates with the inner space 17 of the peripheral wall portion, air can be introduced into the inner space 16 of the seat portion using the pump (anti-tipping unit 13) that introduces air into the inner space 17 of the peripheral wall portion.

[0036] By providing the discharge section 15, when not in use, air can be discharged from the space 17 inside the peripheral wall, allowing the air sofa 10 to be deflated and stored.

[0037] Furthermore, by creating a recessed, bowl-like shape in the center and designating a seating space 21 where the baby sits, the baby's bottom can be inserted into the seating space 21 for use. This helps prevent the baby from slipping out while using the product.

[0038] The present invention has been described above based on the above embodiments. However, the present invention is not limited to the contents of the above embodiments, and can naturally be modified as appropriate without departing from the present invention. In other words, all other embodiments, examples, and operational techniques made by those skilled in the art based on these embodiments are, of course, included in the scope of the present invention.
