[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-310912 Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, it is necessary to attach threaded rods and connecting plates to the column reinforcement, and also necessary to screw in nuts during the connecting work, making the connecting work complicated.

[0005] An object of the present invention is to provide a futon basket which can be transported while being suspended while filled with stuffing and in which the front and back nets can be easily connected. [Means for solving the problem]

[0006] The futon basket of the present invention has a front net 10, a back net 20, and a coil 51 connecting the front net 10 and the back net 20. The futon basket is equipped with a basket body 2 filled with a filling material inside, and a suspender 3 for suspending and transporting the basket body 2 filled with the filling material. The front net 10 and the back net 20 each have vertical lines 10a, 20a and horizontal lines 10b, 20b, and the vertical lines 10a, 20a are bent in a substantially L-shape to form vertical net sections 11, 22, respectively. 1 and bottom mesh portions 12, 22, with a coil 51 connecting the tips of the bottom mesh portion 12 of the front net 10 and the bottom mesh portion 22 of the back net 20, and the hanging device 3 having one hanging portion 3a that rises along the vertical mesh portion 11 of the front net 10 and the other hanging portion 3a that rises along the vertical mesh portion 21 of the back net 20, and a bottom support portion 3b that supports the basket body 2 from below while connecting the hanging portions 3a together.

[0007] In the futon basket, it is preferable that the coil 51 and the supporting portion 3b intersect in a plan view.

[0008] It is also preferable that the length from the base end to the tip of the bottom net portion 12 of the front net 10 is approximately equal to the length from the base end to the tip of the bottom net portion 22 of the back net 20.

[0009] Moreover, it is preferable that the pitch of the vertical lines 10a, 20a is 5.5 times or less the wire diameter of the vertical lines 10a, 20a.

[0010] It is also preferable that the basket body 2 is provided with a side mesh 30, one side end of which is connected to the vertical mesh portion 11 of the front mesh 10 by a coil 52, the other side end of which is connected to the vertical mesh portion 21 of the back mesh 20 by a coil 52, and the lower end of the side mesh 30 is connected to the bottom mesh portion 12 of the front mesh 10 and the bottom mesh portion 22 of the back mesh 20 by the coil 52. Effect of the Invention

[0011] The futon basket of the present invention uses coils to connect the front and back nets, making the connection process simple. Also, because the connection is by coils, the front and back nets can be connected by sewing. Furthermore, because the basket body is supported from below by the hanging fixture, the load on the coils can be shared by the hanging fixture. As a result, the basket can be transported while suspended when filled with filling material.

[0012] In the above-mentioned futon basket, when the coil and the supporting portion intersect in a plan view, the load acting on the coil can be more easily shared by the hanging tool.

[0013] When the lengths of the bottom mesh portion of the front net and the bottom mesh portion of the back net are approximately equal, the degree of bending of the bottom mesh portion of the front net and the bottom mesh portion of the back net during suspended transport will be approximately equal, thereby reducing the load on the coil.

[0014] By setting the pitch of the vertical lines to 5.5 times or less the wire diameter of the vertical lines, the vertical lines are arranged relatively densely, which reduces the deflection of the bottom mesh portion and reduces the load on the coil.

[0015] When the basket body is equipped with a side mesh, one side end of the side mesh is connected to the vertical mesh portion of the front mesh by a coil, the other side end of the side mesh is connected to the vertical mesh portion of the back mesh by a coil, and the lower end of the side mesh is connected to the bottom mesh portion of the front mesh and the bottom mesh portion of the back mesh by a coil, the deflection of the bottom mesh portion can be reduced and the degree of deflection of the bottom mesh portion of the front mesh and the bottom mesh portion of the back mesh can be made closer, thereby reducing the load on the coil connecting the tips of the bottom mesh portion of the front mesh and the bottom mesh portion of the back mesh.

[0017] Next, one embodiment of the futon basket 1 of the present invention will be described in detail with reference to the drawings. The futon basket 1 of the present invention comprises a basket body 2 in which a filling material is filled, and a suspender 3 for suspending and transporting the basket body 2 filled with the filling material.

[0018] The cage body 2 is substantially box-shaped as shown in Fig. 1. For example, the dimensions are a left-right length (width) of 1000 to 3000 mm, preferably 2000 mm or less, a front-rear length (depth) of 800 to 1200 mm, preferably 1000 mm or less, and a height of 300 to 800 mm, preferably 500 mm or less. The cage body 2 includes a front mesh 10 constituting a part of the front and bottom surfaces of the cage body 2, a back mesh 20 constituting a part of the back and bottom surfaces of the cage body 2, a pair of side meshes 30 constituting the sides of the cage body 2, a lid mesh 40 (see Fig. 2) that closes the upper opening of the box body 4 formed by connecting the front mesh 10, the back mesh 20, and the side mesh 30, and a connector 50 for connecting the respective meshes.

[0019] The front mesh 10 is made of a welded wire mesh and has vertical wires 10a and horizontal wires 10b. The vertical wires 10a are bent in an approximately L-shape, so that the front mesh 10 has a vertical mesh portion 11 and a bottom mesh portion 12 as shown in FIG. 2. The vertical mesh portion 11 constitutes the front surface of the cage body 2, and the bottom mesh portion 12 constitutes a part (front half) of the bottom surface of the cage body 2. The height of the vertical mesh portion 11 is preferably 300 to 800 mm, and more preferably 500 mm or less, and the length of the bottom mesh portion 12 (length from the base end to the tip) is preferably 400 to 600 mm, and more preferably 500 mm or less. The ratio of the height of the vertical mesh portion 11 to the length of the bottom mesh portion 12 is 1:2 to 2:1, and more preferably 1:1. Both the vertical wires 10a and the horizontal wires 10b are metal wires, and more preferably zinc-aluminum alloy-plated iron wires. The wire diameter of the vertical wires 10a is preferably 4 mm or more, and the wire diameter of the horizontal wires 10b is preferably 4 mm or more. The pitch of the vertical lines 10a is preferably 22 mm or less. If the pitch is 22 mm when the wire diameter is 4 mm, the pitch is 5.5 times the wire diameter. If the pitch is 5.5 times the wire diameter or less, the vertical lines 10a can be arranged densely relative to the wire diameter, and the deflection of the bottom mesh portion 12 when filled with filling material can be reduced. The pitch of the horizontal lines 10b is preferably 75 mm or less in the vertical mesh portion 11, and 150 mm or less in the bottom mesh portion 12. The pitch of the vertical lines 10a is preferably smaller than the pitch of the horizontal lines 10b.

[0020] The back mesh 20 is also made of welded wire mesh and has vertical wires 20a and horizontal wires 20b. The vertical wires 20a are bent in an approximately L-shape, so that the back mesh 20 has a vertical mesh portion 21 and a bottom mesh portion 22. The vertical mesh portion 21 forms the back surface of the cage body 2, and the bottom mesh portion 22 forms a part (rear half) of the bottom surface of the cage body 2. The height of the vertical mesh portion 21 is preferably 300 to 800 mm, and more preferably 500 mm or less, and the length of the bottom mesh portion 22 (length from the base end to the tip) is preferably 400 to 600 mm, and more preferably 500 mm or less. The ratio of the height of the vertical mesh portion 21 to the length of the bottom mesh portion 22 is 1:2 to 2:1, and more preferably 1:1. It is also preferable that the length of the bottom mesh portion 12 of the front mesh 10 and the bottom mesh portion 22 of the back mesh 20 are approximately equal. The material, wire diameter, and pitch of the vertical wires 20a and horizontal wires 20b are the same as those of the front mesh 10. Therefore, the pitch of the vertical wires 20a is 5.5 times or less than the wire diameter of the vertical wires 20a. However, it is not necessary for them to be all the same and they may be different. If they are all the same, the front net 10 and the back net 20 are the same and there is no structural difference between them.

[0021] The side mesh 30 is also made of welded wire mesh and has vertical lines 30a and horizontal lines 30b. The height is approximately equal to the vertical mesh section 11 of the front mesh 10 and the vertical mesh section 21 of the back mesh 20. The depth is approximately equal to the combined length of the bottom mesh section 12 of the front mesh 10 and the bottom mesh section 22 of the back mesh 20. The material, wire diameter, and pitch of the vertical lines 30a and horizontal lines 30b are the same as those of the front mesh 10 and the back mesh 20, but may be different.

[0022] The cover mesh 40 is also made of welded wire mesh, and has multiple vertical wires 40a arranged in the left-right direction and multiple horizontal wires 40b arranged in the front-rear direction. The wire diameter of the vertical wires 40a and the horizontal wires 40b is preferably 5 mm or more. The pitch of the vertical wires 40a is preferably 100 to 150 mm, and the pitch of the horizontal wires 40b is also preferably 100 to 150 mm. The material of the vertical wires 40a and the horizontal wires 40b is the same as that of the front mesh 10, but may be different.

[0023] The connector 50 is, for example, a coil. The coil is a metal wire, particularly a zinc-aluminum alloy plated iron wire, processed into a spiral shape. The wire diameter is preferably 4 mm or more, and the length (free length) is preferably 500 mm or more. Different coils may be used depending on the part to be used, or the same coil may be used for the entire futon basket.

[0024] The front net 10 and the back net 20 have the tips of the bottom net parts 12, 22 brought close to each other or overlapped, and the tips are connected by a coil 51. Specifically, at least one horizontal wire 10b of the bottom net part 12 of the front net 10 and one horizontal wire 20b of the bottom net part 22 of the back net 20 are inserted into a spiral, and the coil 51 is twisted and advanced in the same direction as the horizontal wires 10b, 20b, to connect the nets in a sewing manner. The coil used in this case is preferably 500 mm or longer in length. It is also preferable that the horizontal wires 10b, 20b are connected by the coil 51 over substantially the entire length.

[0025] One side end of the side net 30 is connected to the vertical net portion 11 of the front net 10, the other side end is connected to the vertical net portion 21 of the back net 20, and the lower end is connected to the bottom net portion 12 of the front net 10 and the bottom net portion 22 of the back net 20. It is preferable to use a coil 52 for connection, and to connect the nets by sewing them together, as in the case of the front net 10 and the back net 20. It is also preferable to use one continuous coil 52 for connecting the lower end of the side net 30 to the bottom net portion 12 of the front net 10 and the bottom net portion 22 of the back net 20. In other words, it is preferable that one coil 52 straddles the front net 10 and the back net 20.

[0026] The cover net 40 is connected to the upper end of the vertical net portion 11 of the front net 10, the upper end of the vertical net portion 21 of the back net 20, and the upper ends of the two side nets 30. The connection work is performed after filling with the filling material. Connection may be by coils 53, or other connecting devices such as U-bolts.

[0027] The sling 3 has one sling part 3a that rises along the vertical net part 11 of the front net 10, the other sling part 3a that rises along the vertical net part 21 of the back net 20, and a support part 3b that supports the cage body 2 from below while connecting the lower ends of the sling parts 3a. This sling 3 is constructed by connecting the ends of a metal wire, particularly a galvanized iron wire, with a wire diameter of 6 mm or more, and then forming it into an oval shape and bending both ends upward. The part that is bent upward and has an inverted V shape when viewed from the front or back is the sling part 3a, and the two approximately parallel straight parts that connect the lower ends of the sling parts 3a are the support parts 3b. The height of the sling part 3a is lower than the heights of the vertical net parts 11 and 21. The length of the support part 3b is approximately the same as the depth of the cage body 2. In plan view, the sling 3 is arranged so that the support portion 3b intersects with the coil 51 that connects the front net 10 and the back net 20. It is also preferable that the support portion 3b is arranged under the coil 51. However, the support portion 3b may pass through the coil 51. The sling 3 is arranged at a position about 1 / 4 of the left-right length of the cage body 2 from the side net 30. The number of slings 3 is not limited to two, and three or more may be provided. Both the hanging portion 3a and the support portion 3b are located outside the cage body 2. In other words, the sling 3 is fitted to the outside of the cage body 2. The sling 3 is fixed to the cage body 2 using, for example, a cable tie, but other methods may be used.

[0028] The cage body 2 may be reinforced with a stay 60. For example, as shown in FIG. 1, the stay 60 may be inserted so as to connect the vertical net portion 11 of the front net 10 and the vertical net portion 21 of the back net 20. In this case, the stay 60 may be disposed near the upper end of the hanging portion 3a of the sling 3 when viewed from the front or back. Alternatively, the stay 60 may be disposed in the center in the left-right direction of the cage body 2. Alternatively, the stay 60 may be provided so as to connect the side nets 30 together. The stay 60 is attached by forming both ends of a single metal wire, particularly a zinc-aluminum alloy-plated iron wire, having a wire diameter of 6 mm or more into a hook shape and hooking it onto the vertical wires 10a, 20a, 30a and the horizontal wires 10b, 20b, 30b.

[0029] The filling material filled in the cage body 2 is so-called crushed stone. Specifically, it is single-grain crushed stone size 1 to 4, with size 4 being particularly preferred. However, it is not limited to crushed stone, and any material that is too large to pass through the mesh may be used, such as natural stone, concrete, bricks, or other objects with a specific gravity greater than that of water. Note that if the particle size exceeds 150 mm, voids are likely to occur when the filling material is filled, so it is preferable to use a particle size of 150 mm or less.

[0030] When the futon basket 1 is lifted up by hanging a hook from a crane or the like on the hanging part 3a with the filling material filled in the basket body 2, the bottom of the basket body 2 tends to bend downwards due to the weight of the filling material. However, it is supported to some extent by the bottom support part 3b. It is also supported to some extent by the rigidity of the vertical line 10a of the front net 10 and the vertical line 20a of the back net 20, and the side net 30 that transmits the tensile force between the vertical net parts 11, 21 and the bottom net parts 12, 22. The rest is mainly supported by the coil 51 that connects the front net 10 and the back net 20, but as mentioned above, it is not supported only by the coil 51, so it can be suspended and transported without cracking at the bottom. In addition, the coil 51 appropriately deforms from a perfect circle to an ellipse, etc. according to the load, so localized concentration of the load is avoided, and the coil 51 can support the load as a whole, and it can be fully handled even when using a filling material that is difficult to fill evenly.

[0031] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention. For example, the materials of the vertical wires 10a, 20a, 30a, 40a and horizontal wires 10b, 20b, 30b, 40b of each net, the coils 51, 52, 53, the hanging tool 3, and the stays 60 can be appropriately changed depending on the location where the futon basket 1 is installed. For example, stainless steel, etc. may be used. [Explanation of symbols]
