Summary of the Invention

Problems to be Solved by the Invention

[0004] In the structures of stretching wires on the bottom surface of the futon cage as in Patent Documents 1 and 2, the futon cage is likely to deform because it is squeezed from multiple directions by the wires during lifting. Therefore, the construction quality is low, and the landscape after use is damaged. The structure of the futon basket with a thick wire rod, as in Patent Document 3, requires the futon basket to be a special product, which increases material costs. Also, it is not possible to retrofit a lifting member to an existing futon basket. The structure using a suspended middle frame prevents deformation of the futon basket by hanging it from a middle frame that is difficult to deform, but the material costs are high because a large amount of rebar is used.

[0005] SUMMARY OF THE INVENTION An object of the present invention is to provide a futon basket and a futon basket lifting structure that can solve the above problems. [Means for solving the problem]

[0006] The futon basket of the present invention comprises a box-shaped basket body having a bottom net and side nets, multiple hanging frames, and multiple connecting members, and the hanging frames each have a horizontal member, two vertical members extending in the same direction from both ends of the horizontal member, and two hook ends formed by folding the tips of the two vertical members back toward the horizontal member, with the horizontal member aligned along the width direction of the bottom surface of the bottom net and the vertical members aligned along the height direction of the inner surfaces of the two side nets through the bottom net, and the vertical members connected to the vertical wire members of the side nets by multiple connecting members.

[0007] The futon basket of the present invention may have a main body panel that is integral with a bottom net and two side nets on both sides of the bottom net in the width direction and has a cross section that is approximately inverted U-shaped.

[0008] In the futon basket of the present invention, the two hook ends may be bent inward of the hanging frame.

[0009] In the bedding basket of the present invention, the connecting member may be a connected coil wound with vertical members and longitudinal wire members.

[0010] In the bedding basket of the present invention, the tips of the hook ends may be wound together with the upright members into the linked coil.

[0011] The futon basket hanging structure of the present invention is characterized by comprising a futon basket, a filling material filled in the futon basket, and a plurality of hanging wires connected to a plurality of hook ends to hang the futon basket. [Effects of the Invention]

[0012] The futon basket and futon basket lifting structure of the present invention is structured so that the bottom net is supported from the bottom by a hanging frame that is roughly inverted U-shaped when viewed from above, so the futon basket is less likely to deform when lifted and construction quality is high. Furthermore, by utilizing the pressure of the filling material pressing the hook end of the hanging frame against the side net, the futon basket can be lifted using a wire rod with a smaller diameter (for example, φ9 mm) than conventional technology. As a result, less iron wire is used than conventional technology, and material costs are lower. Furthermore, by simply setting a hanging frame on a general-purpose futon basket, a high deformation suppression function can be added to the futon basket. [Brief explanation of the drawings]

[0014] The futon basket and the futon basket lifting structure of the present invention will be described in detail below with reference to the drawings. [Example]

[0015] [Futon] <1> Overall configuration (Figure 1) The futon basket 1 is a cage body that has excellent deformation suppression performance when lifted. The futon basket 1 comprises at least a box-shaped basket body 10, a plurality of hanging frames 20, and a plurality of connecting members 30. In this example, three hanging frames 20 and six connecting members 30 are used for one cage body 10. In detail, the three hanging frames 20 are arranged at predetermined intervals within the cage body 10 along the longitudinal direction of the cage body 10, and each hanging frame 20 is connected to the cage body 10 by two connecting members 30. However, the number and positions of the hanging frames 20 and connecting members 30 are not limited to this, and can be selected appropriately depending on the shape of the futon basket 1, the weight of the filling material B, etc.

[0016] <2> Basket body (Figure 1) The basket body 10 is a box-shaped body into which the filling material B is filled. The basket body 10 includes at least a bottom net 11 and four side nets 12. The bottom net 11 is formed by welding a plurality of width wires 11a arranged in parallel with a plurality of depth wires 11b arranged in parallel at their intersections. The side mesh 12 is formed by welding a plurality of vertical wires 12a arranged in parallel with a plurality of horizontal wires 12b arranged in parallel at their intersections. In this example, a main panel 10a having an approximately inverted U-shaped cross section is formed by integrating a bottom mesh 11 and two side meshes 12 in the width direction, and both longitudinal ends of the main panel 10a are blocked with the other two side meshes 12, and a lid mesh (not shown) is provided on top of the main panel 10a. The structure of the cage body 10 is well known and will not be described in detail here.

[0017] <3> Hanging frame (Figure 2) The suspension frame 20 is a member for suspending the cage body 10 with the suspension wires C. The suspension frame 20 comprises at least a horizontal member 21, two vertical members 22 extending in the same direction from both ends of the horizontal member 21, and two hook ends 23 provided at the tips of the two vertical members 22, and is roughly U-shaped when viewed from above. Here, "horizontal" and "vertical" roughly mean "approximately horizontal direction" and "approximately vertical direction." In this example, the suspension frame 20 is constructed by welding a horizontal member 21 and a vertical member 22 made of reinforcing bars at their ends, and welding a hook end 23 to the upper end of the vertical member 22. The length of the horizontal member 21 corresponds to the width of the bottom net 11. The length of the vertical members 22 corresponds to the height of the side net 12 .

[0018] <3.1> Hook end (Fig. 2) The hook end 23 is an end that hooks the suspension wire C. The hook end 23 has a shape in which the tip of the vertical member 22 is folded back toward the horizontal member. The hook end 23 has an insertion portion 23a inside, through which the suspension wire C can be inserted. In this example, the hook end 23 is configured to face inward of the suspension frame 20. In detail, the wire material extends horizontally from the upper end of the vertical member 22 toward the inside of the suspension frame 20, and then extends vertically downward from its tip (FIG. 2(a)). However, the structure of the hook end 23 is not limited to this, and may be, for example, a structure in which the wire material is bent in a loop shape from the upper end of the vertical member 22 toward the inside of the suspension frame 20 (FIG. 2(b)), a structure in which the wire material extends from the upper end of the vertical member 22 in a horizontal direction perpendicular to the extension direction of the horizontal member 21, and then extends vertically downward from its tip (FIG. 2(c)), or a structure in which the wire material is bent in a loop shape from the upper end of the vertical member 22 toward the outside of the suspension frame 20 (FIG. 2(d)).

[0019] <4> Connecting material The connecting member 30 is a member that connects the suspension frame 20 to the side net 12 of the basket body 10. In this example, a steel coil spring is used as the connecting member 30. Coil springs are suitable as connecting members 30 because they can securely hold the vertical members 22 of the hanging frame 20 and the vertical wire members 12a of the side net 12 with multiple ring portions, while elastically absorbing the deflection of the cage body 10 due to the weight of the filling material B when lifting. Note that the connecting members 30 are not limited to coil springs, and may also be shackles or ring-shaped members.

[0020] <5> Installing the hanging frame (Figure 3) The suspension frame 20 is attached to the cage body 10, for example, in the following manner. The hanging frame 20 is inserted from below the basket body 10. More specifically, the horizontal members 21 of the hanging frame 20 are arranged in the width direction of the bottom net 11 (i.e., the extension direction of the width wire members 11a), and the vertical members 22 are inserted upward from below the bottom net 11 through the mesh of the bottom net 11. At this time, the two vertical members 22 are aligned along the inner surfaces of the two opposing side nets 12. The vertical members 22 are connected to the vertical wire members 12a by the connecting members 30. More specifically, the coil spring of the connecting member 30 is rotated and inserted into the mesh of the side net 12 from above. At this time, the vertical wire members 12a of the side net 12 and the vertical members 22 of the hanging frame 20 are wound into the coil of the connecting member 30, thereby mutually restraining the vertical wire members 12a and the vertical members 22.

[0021] <6> Lifting structure (Fig. 4) The lifting structure A is a structure for lifting the futon basket 1 filled with the filling material B. The lifting structure A comprises at least a bedding basket 1, a filling material B filled in the bedding basket 1, and a plurality of hanging wires C connected to a plurality of hook ends 23 to hang the bedding basket 1. In this example, a wire rope is used as the suspension wire C. However, the suspension wire C is not limited to a wire rope, and may be, for example, a metal chain. A hook or shackle is attached to the tip of the hanging wire C, and engages with the hook end 23 of the hanging wire C. A lever hoist or turnbuckle for adjusting the length may also be provided in the middle of the hanging wire C.

[0022] <7> How to use Next, how to use the futon basket 1 will be explained.

[0023] <7.1> Filling of filler material A predetermined amount of filler material B is filled into the basket body 10 of the futon basket 1. As a result, the hook end 23 of the hanging frame 20 is pressed against the inner surface of the side net 12 by the filler material B, thereby preventing deformation of the hook end 23 when lifted. After the filling material B is filled, the filling material B is covered with a lid net (not shown), and the side of the lid net and the upper side of the side net 12 are connected with a coil spring.

[0024] <7.2> Lifting The lower ends of the suspension wires C are hooked onto the insertion portion 23a of the hook end 23, and the upper ends of the suspension wires C are bundled together and sling-hooked onto the crane. The futon basket 1 is lifted up by a crane and lowered to the designated installation location.

[0025] <8> Deformation suppression function (Fig. 5) The bedding basket 1 of the present invention has a deformation suppression function that suppresses deformation of the basket body 10 when lifted, due to the following structures (1) to (3). (1) Support of the bottom net by the horizontal part When the bottom net 11 of the basket body 10 tends to bend downward due to the load of the filling material B, the horizontal members 21 of the hanging frame 20 support the bottom surface of the bottom net 11 from below, thereby preventing the bottom net 11 from bulging out downward. (2) The vertical part restricts the mesh of the bottom net When the depth wires 11b of the bottom net 11 attempt to open due to the load of the filling material B, the horizontal part 21 of the hanging frame 20 and the corners of the vertical members 22 restrict the spacing of the depth wires 11b from the outside of the width direction of the bottom net 11, thereby preventing the opening of the mesh of the bottom net 11. (3) Resistance from the main panel The vertical members 22 of the hanging frame 20 are located on the inside, not the outside, of the side net 12. Furthermore, the vertical members 22 and the vertical wire members 12a of the side net 12 are elastically connected via connecting members 30. Therefore, when the futon basket 1 is lifted, the internal pressure of the filling material B presses the upper part of the side net 12 outward. In this example, the bottom net 11 and the side nets 12 on the two widthwise sides form the main panel 1a with an integral structure, so that the upper parts of the two side nets 12 are pressed outward, applying tension to the upper parts of the width wires 11a of the bottom net 11 and resisting the load of the filling material B. This prevents the bottom net 11 from bulging outward. [Example]

[0026] [Example of wrapping the hook end inside the connecting material] In Example 1, the vertical members 22 of the suspension frame 20 and the vertical wire members 12a of the side net 12 are wound in the coil springs of the connecting members 30 and connected to each other. In this example, a large diameter coil spring is used as the connecting member 30, and in addition to the vertical member 22 and the longitudinal wire member 12a, the hook end 23 is also wound into the coil spring (FIG. 6). In this example, when the bedding basket 1 is lifted, the insertion portion 23a of the hook end 23 can be prevented from opening due to the load of the filling material B. [Explanation of symbols]
