Description

[Technical Field]

[0001] The present invention relates to a fiber futon basket used in bank protection works, drainage works, etc., and in particular to a fiber futon basket improved so that the work of attaching a lid net to the basket body can be carried out safely and easily. [Background technology]

[0002] As an alternative to metal futon baskets, futon baskets made of knitted fiber material are known (Patent Documents 1 and 2). The basic structure of a fiber futon basket comprises a box-shaped basket body that can accommodate a filling material such as stone inside, and a lid mesh that can close the upper opening of the basket body. The bottom net and a plurality of side nets of the basket body are made of a fiber knitted fabric knitted in a lattice pattern, and the lid net is also made of a fiber knitted fabric.

[0003] The basket body filled with the filling material is covered with a lid net and closed as a unit to produce a futon basket. In the case of a metal futon basket, a spiral metal linked coil is wound around the lid net to close it. In the case of fiber futon baskets, they are connected by spirally winding a fiber rope material over the connecting area.

[0004] The process of wrapping the fiber rope material along the mesh of the connecting portion between the basket body and the lid net will now be described in detail. The rope is wound in a spiral by repeatedly pinching the tip of the rope with the fingers and inserting it into the mesh, then inserting the hand into the mesh, grabbing the tip of the rope, and pulling it out of the mesh.

[0005] [Patent Document 1] Patent No. 6757869 [Patent Document 2] Patent No. 7445803 Summary of the Invention [Problem to be solved by the invention]

[0006] Conventional futon baskets have the following inherent problems: <1> The filling material gets in the way, making it difficult to insert the tip of the rope material into the mesh and pull it out of the mesh. Even for experienced technicians, winding the rope around the mesh once takes 10 to 20 seconds, a task that must be repeated at intervals of 10 to 15 cm. Furthermore, they are forced to wind up the long rope for each mesh. Therefore, the work efficiency when winding rope material around the multiple mesh holes formed at the connection between the basket body and the lid net is low, and it takes a lot of time and effort to connect the basket body and the lid net. <2> When winding the rope material, the worker's fingers are easily injured by rubbing against the filling material, which is dangerous. <3> The above-mentioned problems also occur when a metal linked coil is used to close a lid net of a fiber futon basket. <4> In the civil engineering industry, problems such as the aging of workers and the difficulty in securing skilled engineers are becoming more serious every year. The same is true at construction sites for futon baskets, and there is a demand for proposals for futon baskets that can be constructed efficiently even by workers with low levels of skill.

[0007] To provide a fiber futon basket that can be installed safely and efficiently even by elderly people or workers without skilled techniques, the present invention has been made to solve the above problems. [Means for solving the problem]

[0008] The present invention provides a fiber futon basket comprising a box-shaped basket body capable of accommodating filler therein, and a lid net capable of closing the upper opening of the basket body, the basket body comprising at least a bottom net and a plurality of side nets erected around the outer periphery of the bottom net, A widening section is provided on the upper edge of a part or all of the side nets in the height direction of the side nets, a hinge is provided between the upper edge of the side nets and the widening section, the widening section is configured to be foldable via the hinge, and a plurality of binding bands are attached in advance along the widening section, The plurality of binding bands are bound together to connect a lid net along the upper edge of the side net of the basket body. 。 BookIn another aspect of the invention, the tie is one of a string, a rope, a tie band, or a tie belt. In another form of the present invention, the basket body may have a rectangular bottom net, a front net connected to one of the opposing long sides of the bottom net and standing vertically from the bottom net, a rear net connected to the other opposing long side of the bottom net and standing vertically from the bottom net, and an end net connected to one of the opposing short sides of the bottom net and standing vertically from the bottom net. In another embodiment of the present invention, the heights of a pair of opposing side meshes of the basket body may be different. In another embodiment of the present invention, the cage body may be a multiple cage body in which a plurality of storage spaces are defined by one or more partition nets. [Effects of the Invention]

[0009] The present invention has at least one of the following advantages. <1> Since a plurality of binding bands are attached in advance to the upper edge parts of specific side nets of the basket body, after filling with the filling material, the binding bands exposed on the surface of the filling material can be easily grasped through the lid net, and the lid net can be easily and safely connected using the binding bands. <2> The conventional method of closing the lid, which involves winding a long rope material in a spiral, required one worker to determine the order in which the lids were closed. In the present invention, the lid net can be closed from anywhere by using a binding band provided on the upper edge of a specific side net of the basket body, so that the conventional work of winding a long rope material in a spiral shape or the winding of a long rope material for each mesh is not required. <3> Before the lid net is closed, the binding band is exposed on the surface of the filling material, so that there is no need to manually move the filling material after the lid net is put on. <4> As mentioned above <1> ~ <3> As a result, the work of connecting the lid nets can be made more efficient, which makes it possible to reduce the labor and time required to manufacture futon baskets on site compared to conventional methods. <5> By extending an expanded portion to the upper edge of the side net and attaching multiple cable ties along the expanded portion, the cable ties have more flexibility in binding and are easier to bind, which further reduces the time required to connect the lid net compared to when no expanded portion is provided. <6> To efficiently attach a binding band to a cage body that is not filled with a filling material in a place with a good working environment. Therefore, since the basket body delivered to the site has multiple tying bands attached, there is no need to attach tying bands later on site, which saves labor in the manufacturing process of the futon basket. <7> At the site, the simple task of pulling the exposed cable ties on the surface of the filling material out of the lid net and tying them down is all that is required. Therefore, even elderly workers or workers without skilled techniques can safely and efficiently lay the futon baskets. <8> Since the binding bands are attached in advance at predetermined intervals to specific side nets of the basket body, it is easy to check for any loose binding in the lid net, and the lid net can be attached firmly and reliably. <9> If the cage body and the cable tie are handled separately, management at the installation site becomes cumbersome. In the present invention, the cage body and the wrapper straps are handled in an integrated form without being separated, which makes management at the installation site easier.

DETAILED DESCRIPTION OF THE INVENTION

[0011] The present invention will be described in detail below with reference to the drawings. [Example]

[0012] <1> Overview of fiber futon baskets The description will be made with reference to FIGS. The fiber futon basket (hereinafter referred to as "futon basket") 10 of the present invention comprises a box-shaped basket body 20 capable of storing a filling material 50 such as stone inside, a lid mesh 30 capable of sealing the upper opening of the basket body 20, and a connecting means for the lid mesh 30.

[0013] The basket body 20 and the lid net 30 are made of a woven fabric made of fibers woven in a lattice pattern. "Fiber" includes chemical fibers such as polyester fibers and polyethylene fibers, as well as synthetic resin knitted fabrics made by impregnating chemical fiber knitted fabrics with resin and hardening them.

[0014] <2> Basket body The basket body 20 is a box body with an open top, which comprises at least a rectangular bottom net 21 and a plurality of band-shaped side nets 22 erected around the outer periphery of the bottom net 21. It may also be a structure in which one or more partition nets 23 are erected inside the basket body 20 (Fig. 2). In this example, the side net 22 will be described as including the partition net 23.

[0015] The side nets 22 can be folded at the connection portions with the bottom net 21 from a state of being flush with the bottom net 21 and can be set upright perpendicular to the bottom net 21. The bottom net 21 and the side net 22 may be a structure formed continuously from the same material, or the bottom net 21 and the side net 22 may be a structure formed from separate parts connected via a known hinge or the like. The joint ends of adjacent side nets 22 are joined by joining means 24 such as a connecting coil or rope material.

[0016] <2.1> Side net In this example, we will explain a form in which the side net 22 is composed of a front net 22a and a rear net 22b, which are belt-shaped and connected to opposing long sides of the bottom net 21, and a pair of end nets 22c, which are belt-shaped and connected to opposing short sides of the bottom net 21.

[0017] <2.2> Mesh that constitutes the basket body The knitted fabrics that make up the bottom net 21 and the multiple side nets 22 (front net 22a, rear net 22b, end net 22c, partition net 23) are each made of a fiber netting body in which multiple warp strands and weft strands are knitted in a lattice pattern using Raschel knitting, and the net surface has multiple square meshes 20a. The size of the mesh 20a can be selected appropriately taking into consideration the size of the filler 50, but is set to a size that can prevent the filler 50 from passing through. In practice, the size of the mesh 20a is 3 to 10 cm.

[0018] <3> Lid net connection means (tie) In the present invention, a plurality of ties 40 are used as a means for connecting the lid net 30. A plurality of wrappers 40 are attached in advance to some of the side nets 22 that constitute the basket body 20.

[0019] <3.1> Examples of cable ties The tie band 40 may be a fiber string, rope, tie band, tie belt, or the like. In practice, a fiber string rope is suitable, and a binding band 40 made of a doubled string rope is attached by tying it to the strands at the upper edge of the side net 22 (see FIG. 3(A)).

[0020] <3.2> When to install cable ties A plurality of binding bands 40 are attached in advance to the upper side of the side net 22 of the basket body 20. "In advance" refers to the time when the futon basket 10 is shipped or immediately before the filling material 30 is filled.

[0021] The reason why a plurality of binding straps 40 are attached to the basket body 20 in advance is to simplify the work of fixing the lid net 30, thereby reducing the number of steps required to assemble the futon basket 10 on-site and increasing the work efficiency of assembling the futon basket 10.

[0022] <3.3> Length and number of installations of cable ties The length of the tie band 40 is selected appropriately so that the tie band 40 can be tied to the lid net 30 by hand. For practical purposes, a length of about 20 to 25 cm is sufficient. The number of wrappers 40 to be installed can also be selected appropriately.

[0023] <3.4> What to attach the cable tie to A plurality of binding bands 40 are attached along the upper edge of at least one of the front side net 22a, the rear side net 22b, the end side nets 22c, 22c and the partition net 23 that constitute the side nets 22 of the basket body 20. In this example, a configuration in which the wrappers 40 are attached to the front mesh 22a on the long side and the end mesh 22c on the short side will be described.

[0024] <4> lid net The lid net 30 is a knitted fabric that closes the upper opening of the basket body 20. The knitted fabric that constitutes the lid netting 30 is made of a fiber netting body in which multiple warp strands and weft strands are knitted in a lattice pattern using Raschel knitting, and the net surface has multiple square meshes 30a. The mesh size 30a of the lid net 30 is in the range of 3 to 10 cm, similar to the mesh size of the side net 22.

[0025] The lid net 30 may be in a single form that is adapted to the size of the upper opening of the basket body 20 as shown in FIG. 1, or may be in a form that can straddle and cover a plurality of basket bodies 20.

[0026] [How to lay a futon] Next, a method for laying out the futon basket 10 will be described.

[0027] <1> Assembling the basket body The cage body 20 is carried to the site. The cage body 20 is carried in a flat, unfolded state, and the three-dimensional cage body 20 is assembled on site. The cage body 20 may be transported to the site in the form of a three-dimensional box. Regardless of the carrying-in form, it is sufficient that a plurality of binding bands 40 are attached to the upper edge portion of a specific side net 22 that constitutes the basket body 20.

[0028] <2> Filling of filler material The cage body 20 is filled with the filler material 50 in the same manner as in the conventional method. The filler material 50 is selected from crushed stone, natural stone, concrete rubble, etc. depending on the application. The binding bands 40 attached to the basket body 20 do not interfere with the filling work of the filler material 50, and there is no risk of the binding bands 40 coming off or being damaged by the filling work of the filler material 50. When filling the filler material 50, if a part of the wrapping band 40 is buried in the filler material 50, the wrapping band 40 is grasped by hand and pulled out to the outside of the filler material 50 to be exposed.

[0029] <3> Lid mesh covering After the filling of the filling material 50 has been completed, the top surface of the basket body 20 is covered with the lid net 30. The lid net 30 may be of a size that can cover one basket body 20, or may be of a size that can cover a plurality of basket bodies 20 across one another.

[0030] <4> Attaching the lid net with cable ties Next, each of the tying bands 40 is used to tie and secure the basket body 20 and the lid net 30 together. Figure 4(A) shows a configuration in which adjacent portions of individual lid nets 30 are connected to the side net 22 of the basket body 20, and Figure 4(B) shows a configuration in which a continuous lid net 30 is connected to the side net 22 of the basket body 20.

[0031] The method of fixing using the wrapper band 40 will be described in detail. A hand is inserted through the mesh 30a from above the lid net 30 toward the basket body 20 side, and both ends of the binding band 40 exposed on the surface of the filling material 50 are grasped with fingers and pulled out to the outside of the lid net 30. The lid net 30 can be fixed to the basket body 20 by a simple operation of simply tying both ends of the pulled-out binding band 40 to a part of the lid net 30.

[0032] Since the wrapping bands 40 are attached in advance to the basket body 20 along specific side nets 22, there is no need to attach the wrapping bands 40 to the basket body 20 after filling with the filling material 50. At the work site, both ends of the cable tie 40 are exposed on the surface of the filler material 50, so that both ends of the cable tie 40 can be easily grasped by hand even through the mesh 30a of the cover net 30. Therefore, the work of pulling out the cable tie 40 exposed below the lid net 30 to above the lid net 30 and the work of tying the pulled out cable tie 40 to the lid net 30 can be easily performed in a short time. When pulling out the binding band 40 and binding the binding band 40, it is no longer necessary for the worker to forcibly insert his / her fingers into the narrow gap of the filler material 50, and therefore injuries to the fingers of the worker can be prevented.

[0033] In the conventional fastening method in which a long rope material is wound and fastened, only one worker could perform the connecting work in one connecting section. In contrast, in the present invention, a plurality of wrapper straps 40 are arranged on the basket body 20 along the binding direction, so that a plurality of workers can carry out the binding work at a plurality of locations in parallel. In this way, not only is it unnecessary to attach the binding straps 40 to the cage body 20 on-site, but workers can share the work of connecting one connecting section. Furthermore, there is no need to wind up a long rope material for each mesh. Therefore, compared to the conventional fixing method of winding and fixing a long rope material, the work efficiency is improved, and the time and labor required to connect the basket body 20 and the lid net 30 can be significantly reduced.

[0034] Furthermore, when adjusting the amount of filler material 50 after closing the lid net 30, it is possible to easily untie some of the binding bands 40, roll up the lid net 30 in part, and add more filler material 50 or remove part of the filler material 50.

[0035] [Modification of the basket body] The futon basket 10 according to the present invention is not limited to the above-described configuration. Below, examples of modified examples of the basket body 20 to which the present invention can be applied will be given.

[0036] <1> Multi-connected cage body FIG. 5 shows a modified example of a multiple-type cage body 20 in which a plurality of storage spaces S for filling materials are defined by a plurality of partition nets 23. The side nets and partition nets of the multi-connected basket body may be formed by folding a single piece of knitted fabric, or the side nets and partition nets may be formed from knitted fabric that is a separate member from the bottom net.

[0037] <2> A pair of opposing side nets with different heights It is also possible to apply this to a basket body 20 in which a pair of side meshes 22 on opposing long sides or opposing short sides are combined at different heights.

[0038] FIG. 6(A) shows a modified example of the basket body 20 in which the rear mesh 22b is lower than the pair of front meshes 22a facing each other on the long side. By providing a difference in height between the opposing front mesh 22a and rear mesh 22b, when multiple basket bodies 20 are laid flat, it is possible to prevent the pair of adjacent side meshes 22a, 22b from being doubled up over the entire height, thereby reducing the amount of knitted fabric used (Figure 6(B)).

[0039] FIG. 7 shows a modified example of a multiple-type basket body 20 in which a pair of opposing side nets 22 (front net 22a, rear net 22b) are combined at different heights. [Example]

[0040] 1. Configuration <1> Fiber futon Another futon basket 10 of the present invention will be described with reference to Figs. The futon basket 10 according to this embodiment comprises a basket body 20 and a lid net 30. In this embodiment, a foldable widening portion 26 is extended via a hinge 25 to the upper end edge (top edge) of the side mesh 22 to which the cable ties 40 are to be attached, and multiple cable ties 40 are attached along this widening portion 26.

[0041] This example can be applied to the various types of cage body 20 explained in the modified examples above.

[0042] <2> Dimensional relationship between side net with and without cable ties In this example, the widened portion 26 is formed only on the side mesh 22 to which the wrapper band 40 is to be attached, and the other side meshes 22 to which the wrapper band 40 is not to be attached do not have the widened portion 26. Therefore, the height dimension of the side net 22 is the same for the side net 22 with the widening section 26 and the other side net 22 without the widening section 26, but the overall height of the side net 22 with the widening section 26 when unfolded is longer by the extension of the widening section 26.

[0043] <3> Widening section The widened portion 26 is a portion that extends in the height direction of the side net 22 by one or more meshes, and is formed continuously over the entire length of the side net 22 in the lateral direction. The extension length of the widened portion 26 can be selected as appropriate, but a dimension obtained by extending about one or two meshes (for example, about 3 to 10 cm) is sufficient. The widened portion 26 may be formed of a knitted fabric that is integral with the side netting 22, or may be formed of a separate knitted fabric that is connected to the side netting 22 so as to be tiltable.

[0044] <4> hinge The widened portion 26 added to the upper edge of the side net 22 can be bent (tilted) via a hinge 25 . When the widened portion 26 is formed of a knitted fabric integral with the side mesh 22, it is known to form the hinge 25 by making the hardness of the knitted fabric lower than that of other portions (for example, Japanese Patent Nos. 6770212 and 6770213). When the widened portion 26 is formed of a knitted fabric separate from the side netting 22, a known hinge member is used.

[0045] <5> Reason for making the widening section bendable The widening section 26 added to the upper edge of the side net 22 is configured to be foldable around the hinge 25 so as not to adversely affect the filling height of the filler material 50 and to make it easier to tie the lid net 30 with the tie band 40 after filling the filler material 50.

[0046] 2. How to lay the futon basket Next, a method for laying out the futon basket 10 in this example will be explained.

[0047] <1> Assembling the basket body The cage body 20 with a plurality of binding bands 40 attached to the widened portions 26 at the upper edges of some of the side nets 22 is carried to the site and assembled into a box shape.

[0048] <2> Filling of filler material As shown in FIG. 9(A), the basket body 20 is filled with the filler material 50. When filling the filler material 50, the height of the upper end edges of the side walls 22 is used as a guide, so when filling the filler material 50, the widened part 26 is bent outward to make the height of the upper end edges of all the side walls 22 the same. Therefore, it is possible to fill the basket body 20 with a predetermined amount of filler material 50 without excess or deficiency.

[0049] When the binding band 40 is drawn in during filling of the filler material 50, the embedded binding band 40 is pulled out after filling to the outside and exposed on the upper surface of the filler material 50.

[0050] <3> Lid mesh covering After the filling of the filling material 50 is completed, the top surface of the basket body 20 is covered with the lid net 30.

[0051] <4> Attaching and fixing the lid net with cable ties A method for attaching the lid net 30 using the binding bands 40 will be described with reference to FIG. 9(B). A hand is inserted from above the lid net 30 through the mesh 30a, and the binding band 40 exposed on the surface of the filling material 50 is pulled out and bound and connected to the lid net 30. The tiltable widening portion 26 and the tying strap 40 are exposed on the top surface of the filling material 50, which not only makes it easy to grasp the tying strap 40 through the mesh of the lid net 30, but also makes it easier to tie the side net 22 of the basket body 20 and the lid net 30 together.

[0052] In particular, the side net 22 of the basket body 20 is prone to deformation when the filling material 50 is filled. Even if the side net 22 is deformed, the binding band 40 extends by the projection length of the widened portion 26, so that the binding work with the lid net 30 can be performed using the binding band 40 without being affected by the deformation of the side net 22. Therefore, compared to the previous first embodiment, the work of binding the side net 22 of the basket body 20 and the lid net 30 with the binding band 40 is easier, and work efficiency is significantly improved.
