Description

The present invention relates to a futon basket.

Traditionally, in river and coastal bank protection construction and mountain slope reinforcement construction, the cage is filled with crushed stone or other filling material, then lifted up by heavy machinery and lowered to the desired installation location. In recent years, fiber futon cages have been used in place of iron wire futon cages to prevent corrosion and reduce weight (see, for example, Patent Document 1).

JP 2001-348833 A

However, in the futon basket in Patent Document 1, there is a risk that the hanging rope will bite into the bottom of the cage, causing deformation, when the futon basket is suspended by heavy machinery. Also, if the hanging rope bites into the bottom of the cage when the futon basket is suspended by heavy machinery, not only will the cage be deformed, but the filling material will become biased inside the cage, causing the cage to become unbalanced when suspended down, making it difficult to suspend it or to position it neatly in the designated position.

The present invention was made in consideration of the above points, and aims to provide a futon basket that is simple in construction, prevents deformation when lifted by heavy machinery, and is easy to operate.

To solve this problem, the futon cage of the present invention is equipped with a cage body having a hexahedral shape made of woven metal fabric for storing sandbags with belts attached integrally to the outside, and a hanging member that is placed above the cage body and entangles the belt of the sandbag to hold the sandbag so that it can be suspended within the storage space of the cage body.

In the present invention, it is preferable that the cage does not have a top panel that covers the top surface of the storage space, and that the hanging member is formed by connecting one end side and the other end side of the hanging member to rope-like members that are respectively attached to the opposing ends of the cage.

In the present invention, the cage has a top panel that covers the top surface of the storage space, and the hanging member has a fixed frame body fixed to the top panel and is rotatably attached to the fixed frame body, and the belt of the sandbag pulled outward through the gaps in the mesh of the top panel is preferably entangled and wound up around a rod-shaped member rotatably supported by the fixed frame body, thereby holding the sandbag in a suspendable state within the storage space of the cage.

In the present invention, it is preferable that the rod-shaped member is provided with a rotation stop rod for holding the belt in a wound state by entangling it.

In the present invention, it is preferable that the cage has a top panel that covers the top surface of the storage space, the hanging member has a fixed frame that is fixed to the top panel, and the belt of the sandbag that is pulled outward through the gaps in the mesh of the top panel is entangled with the fixed frame, and the sandbag is held in a suspendable manner within the storage space of the cage via the belt.

Despite its simple structure, it is possible to prevent deformation when lifted by heavy machinery, and create a futon basket that is easy to operate.

1. Specific Examples of the Embodiments (1-1) First embodiment The overall structure of the futon basket according to the first embodiment of the present invention will be described in detail below with reference to Fig. 1 and Fig. 2. Fig. 1 is a schematic perspective view showing the overall structure of the futon basket according to the first embodiment of the present invention. Fig. 2 is a schematic perspective view showing the structure of the cage body and hanging members of the futon basket according to the first embodiment of the present invention.

In Fig. 1, the direction of arrow a is the upper side or upward, and the direction of arrow b is the lower side or downward. Also, in Fig. 1, the direction of arrow c is one end side or one side, and the direction of arrow d is the other end side or the other side. Furthermore, in Fig. 1, the direction of arrow e, i.e., the near side, is the front side or forward, and the direction of arrow f, i.e., the depth side, is the rear side or rear, in the following explanation. However, these directions are used merely for convenience of explanation, and do not necessarily match the directions during actual use.

As shown in FIG. 1, the futon basket 100 mainly comprises a cage body 20 having an overall rectangular parallelepiped shape, a hanging member 30 that is placed above the cage body 20 when the futon basket 100 is suspended by heavy machinery (not shown), and a sling rope 40 that physically connects the cage body 20 and the hanging member 30.

As shown in FIG. 2, the cage 20 has a hexahedral shape made of a metal weave. The cage 20 includes a first front panel portion 21a, each of whose faces is formed in a lattice pattern, a second front panel 21b arranged opposite the first front panel 21a, a first side panel 22a and a second side panel 22b arranged perpendicular to the first front panel portion 21a and the second front panel 21b and arranged opposite each other, and a bottom panel 23 formed by bridging a thin plate-shaped bottom material 23a between the lower ends of the first front panel 21a and the second front panel 21b. Although the cage 20 has a hexahedral shape, it does not have a top panel that covers the top surface.

The first front panel 21a and the second front panel 21b are the same size and are arranged parallel to each other. The first side panel 22a and the second side panel 22b are also the same size and are arranged parallel to each other. In this case, the first front panel 21a and the second front panel 21b and the first side panel 22a and the second side panel 22b have the same height.

On the other hand, the first front panel 21a and the second front panel 21b are formed to be longer horizontally than the first side panel 22a and the second side panel 22b, so that the cage body 20 is formed to be rectangular in plan and side views. However, this is not limited to this, and the cage body 20 may be formed to be trapezoidal in plan and side views without a top panel.

In practice, the first front panel 21a and the second front panel 21b have a length of 2 m in the longitudinal direction (arrow cd direction), and the first side panel 22a and the second side panel 22b have a width of 1.2 m in the depth direction (arrow ef direction) and a height of 1 m. However, this is not limited to this, and they may be formed in various other sizes.

The first front panel 21a, the second front panel 21b, the first side panel 22a, the second side panel 22b and the bottom panel 23 are connected to each other by connecting members such as shackles (not shown) to maintain the hexahedral shape.

The cage 20 has a space inside that can accommodate the sandbags 50. In this case, the cage 20 is large enough to accommodate two sandbags 50. In practice, the sandbags 50 are formed by filling a filler material such as soil, sand, or stones inside a bag 51 made of cloth, for example. A belt 52 of a predetermined length is attached integrally to the outer surface of the sandbag 50.

Here, the two sandbags 50 are shown as cylindrical, but they can be deformed depending on the flexibility of the fabric of the bag body 51 and the size and amount of soil and sand inside. The cage body 20 can be placed close to the two sandbags 50 so that the area of contact between them is large. Incidentally, the cage body 20 may be large enough to accommodate one sandbag 50 or three or more sandbags 50.

The hanging member 30 is arranged parallel to the first front panel 21a and the second front panel 21b, is made of H-shaped steel formed to the same length as the first front panel 21a and the second front panel 21b, and is the part that is suspended by heavy machinery (not shown). The hanging member 30 has U-bolts 31 to 34 attached to the upper and lower ends of one end side and the other end side on one face of the flange of the H-shaped steel.

The hanging member 30 has U-bolts 35 and 36 attached to one side of the flange of the H-shaped steel, above and on the inside of one end side and above and on the inside of the other end side. The U-bolts 35 and 36 are larger than the U-bolts 31 to 34, and are sized to allow the belt 52 of the sandbag 50 to pass through the width of the U-shape.

The belt 52 of the sandbag 50 is entangled with the hanging member 30 via U-bolts 35, 36, and the sandbag 50 is restricted from moving to one end or the other end in the direction of arrows cd on the hanging member 30. In practice, the belt 52 of the sandbag 50 is hung on the hanging member 30, and then the U-bolts 35, 36 are attached to the hanging member 30, so that the belt 52 of the sandbag 50 is entangled with the hanging member 30.

The hanging member 30 is connected to the four corners of the cage body 10 by a sling rope 40. The sling rope 40 is a means generally used when lifting and moving heavy objects without damaging them. In this case, for example, a sling belt made of a soft cloth material can be used.

In practice, one end of the sling rope 40 is wound around the hanging member 30 and passed through both the upper U-bolt 31 and the lower U-bolt 32 on one side of the flange of the hanging member 30, with one end and the other end of the rope tied to the two ends of the cage 20 that face each other and are closest to each other among the four ends. In this case, the distance between the hanging member 30 and the cage 20 is adjusted according to the amount of the sling rope 40 wound around the hanging member 30 when the hanging member 30 is suspended by heavy machinery.

Similarly, the sling rope 40 on the other end is wound around the hanging member 30 and passed through both the upper U-bolt 33 and the lower U-bolt 34 on one side of the flange of the hanging member 30, with one end and the other end of the rope tied to the two closest ends of the cage body 20. In this case too, the distance between the hanging member 30 and the cage body 20 is adjusted depending on the amount of the sling rope 40 wound around the hanging member 30 when the hanging member 30 is suspended by heavy machinery. Therefore, the sling rope 40 on one end and the sling rope 40 on the other end are adjusted so that the distance between the hanging member 30 and the cage body 20 is the same.

The distance between the hanging member 30 and the cage body 20 is set to a length that prevents the weight of the sandbag 50 from acting as a load on the bottom panel 23 of the cage body 20 when the hanging member 30 is hung by heavy machinery and the sandbag 50 connected to the hanging member 30 by the belt 52 is lifted at the same time.

Specifically, it is preferable that the sandbag 50 does not contact the bottom panel 23 of the cage body 20, or only slightly contacts it. In other words, by entangling the belt 52 of the sandbag 50 with the hanging member 30, when the hanging member 30 is suspended by heavy machinery, the weight of the sandbag 50 is not placed as a load on the bottom panel 23 of the cage body 20, and the sandbag 50 can be held in a suspendable manner within the storage space of the cage body 20.

In the above configuration, when the futon basket 100 is hung at one or two points by the sling wire (not shown) of heavy machinery or the like, the hanging member 30 and the cage body 20 connected by the sling rope 40 are simultaneously lifted. At this time, the sandbag 50 with the belt 52 entangled with the hanging member 30 is also lifted together with the hanging member 30 without coming into contact with the bottom panel 23 of the cage body 20.

As a result, when the futon basket 100 is suspended by heavy machinery, the weight load of the sandbags 50 is not placed on the cage body 20, and deformation of the cage body 20 due to the weight load of the sandbags 50 can be prevented in advance.

When the futon basket 100 is suspended at one point by heavy machinery, the hanging member 30 may not be kept horizontal and may tilt; however, even in this case, the sandbag 50 is prevented from moving to one end or the other end of the cage body 20 in the internal space of the cage body 20 because the belt 52 of the sandbag 50 is passed through the U-bolts 35, 36 of the hanging member 30. This prevents the sandbag 50 from placing a weight load on the first side panel 22a and the second side panel 22b, and prevents deformation of the cage body 20.

(1-2) Second embodiment The overall configuration of the futon cage according to the second embodiment of the present invention will be described in detail below with reference to Figs. 3 to 6. Fig. 3 is a schematic perspective view showing the configuration of the futon cage according to the second embodiment of the present invention. Fig. 4 is a front view and a plan view showing the configuration of the futon cage according to the second embodiment of the present invention. Fig. 5 is a schematic perspective view showing the external configuration of the fixing frame of the hanging member in the futon cage according to the second embodiment of the present invention. Fig. 6 is a schematic perspective view showing the state before the belt of the sandbag is wound in the futon cage according to the second embodiment of the present invention.

As shown in FIG. 3, in which parts corresponding to those in FIG. 1 are given the same reference numerals, the futon basket 200 in the second embodiment mainly comprises a cage body 120 having an overall rectangular parallelepiped shape, and a hanging member 130 that is disposed above the cage body 120 and attached integrally to the cage body 120 when the futon basket 100 is suspended by heavy machinery (not shown).

The cage body 120 has a similar configuration to the cage body 20 in the first embodiment, and has a hexahedral shape made of woven metal fabric. Like the cage body 20 in the first embodiment, the cage body 120 has a first front panel portion 21a, a second front panel 21b, a first side panel 22a, a second side panel 22b, and a bottom panel 23. In addition to these, the cage body 120 also has a top panel 24 formed by bridging a thin plate-shaped top material 24a between the upper ends of the first front panel 21a and the second front panel 21b.

The cage 120 has a space inside that can accommodate the sandbags 50, and in this case is large enough to accommodate, for example, two sandbags 50. After the two sandbags 50 are accommodated in the cage 120, the top panel 24 is connected to the first front panel portion 21a, the second front panel 21b, the first side panel 22a, and the second side panel 22b by connecting members such as shackles.

The hanging member 130, which is disposed above the cage body 120, has a hanging body 140, a fixed frame body 150, and a sling rope 40 that connects the hanging body 140 and the fixed frame body 150. The hanging body 140 is a rectangular member having four sides whose longitudinal length is equal to that of the top panel 24 but whose transverse length is shorter than that of the top panel 24.

The suspension body 140 is a rectangular member, for example, with four sides made of rectangular steel beams with a square cross section, and has vertical frame members 141a, 141b and horizontal frame members 142a, 142b. Note that the vertical frame members 141a, 141b and horizontal frame members 142a, 142b of the suspension body 140 are not limited to rectangular steel beams, and for example, H-shaped steel beams or various other types of steel beams or steel bars with a circular, square, polygonal, or other cross section can be used.

The suspension body 140 is made up of vertical frame members 141a and 141b arranged parallel to each other along the short side direction, and horizontal frame members 142a and 142b arranged parallel to each other along the long side direction, which are joined together by screws, welding, etc.

The fixed frame 150 is a rectangular member having the same overall size as the hanging body 140, similar to the hanging body 140. The fixed frame 150 is a rectangular member having four sides made of rectangular steel bars with a square cross section, for example, and has vertical frame members 151a, 151b and horizontal frame members 152a, 152b. Note that the vertical frame members 151a, 151b and horizontal frame members 152a, 152b of the fixed frame 150 are not limited to rectangular steel bars, and various other cross-sectional shapes of steel bars, such as round steel bars, can be used.

The fixed frame 150 is made up of vertical frame members 151a and 151b arranged parallel to each other along the short side direction, and horizontal frame members 152a and 152b arranged parallel to each other along the long side direction, which are joined together by screws, welding, or the like. The fixed frame 150 is then joined together with the top panel 24 of the cage 120 by a joining member such as a shackle.

The fixed frame 150 also supports a sandbag belt winding body 155, which is made of, for example, square steel, at the center of the vertical frame members 151a and 151b so as to span between the vertical frame members 151a and 151b. The sandbag belt winding body 155 may be made of not only square steel but also shaped steel or bar steel.

The sandbag belt winding body 155 has two approximately L-shaped belt fasteners 156 attached to any one surface of the square steel. In this case, the belt fasteners 156 are provided in positions that make it easy to wind the belt 52 of the sandbags 50 stored in the cage body 120. In other words, the belt fasteners 156 are provided in any number and positions depending on the number, size, and other factors of the sandbags 50 that can be stored in the cage body 120.

The sandbag belt winding body 155 is supported by a bearing or the like (not shown) on the vertical frame members 151a and 151b so as to be rotatable in both the forward and backward directions. However, this is not limited to this, and the sandbag belt winding body 155 may be supported by a bearing or the like on the vertical frame members 151a and 151b so as to be rotatable by sliding without using a bearing or the like.

The sandbag belt winding body 155 has a through hole 155h formed in its center. A rotation stop bar 157 for stopping the rotation of the sandbag belt winding body 155 is inserted into this through hole 155h. The rotation stop bar 157 is formed so that its diameter is approximately the same as or slightly smaller than the through hole 155h of the sandbag belt winding body 155. The rotation stop bar 157 is formed so that its length is longer than the distance between the horizontal frame members 152a and 152b.

The sling rope 40 is a sling belt made of soft cloth material used in the futon basket 10 in the first embodiment, and is tied between the four corners of the hanging body 140 and the four corners of the fixed frame body 150. There is no particular restriction on the method of tying the sling rope 40, and it can be tied in any manner.

In this case, the suspending body 140 and the fixed frame body 150 are the same size, and since the suspending body 140 can be placed directly above the fixed frame body 150, the four sling ropes 40 are stretched in a straight line from top to bottom. Incidentally, in this case, the sling ropes 40 do not have to be limited to sling belts made of cloth, and various other types of suspending ropes, such as metal sling wires, can be used.

In the above configuration, the futon basket 200 accommodates two sandbags 50 inside the cage body 120, and then attaches the top panel 24, so that the two sandbags 50 are accommodated in the accommodation space of the cage body 120 and are covered with the top panel 24.

Next, as shown in FIG. 6, the belt 52 of the sandbag 50 is pulled out from the gap between the multiple top panel members 24a of the top panel 24 and entangled so as to straddle both the horizontal frame members 152a and the horizontal frame members 152b from the outside. At this time, the belt 52 is passed between the surface of the sandbag belt winding body 155 and the approximately L-shaped belt fastener 156. After that, the fixed frame body 150 of the hanging member 130 is attached and fixed integrally to the top panel 24.

As a result, the belt 52 of the sandbag 50 is integrated with the cage body 120 while being entangled with the horizontal frame members 152a, 152b of the fixed frame body 150 and the belt fastener 156 of the sandbag belt winding body 155. The worker then rotates the sandbag belt winding body 155 in the direction of the arrow to wind the belt 52 of the sandbag 50 around the sandbag belt winding body 155.

By adjusting the amount of the belt 52 of the sandbag 50 wrapped around the sandbag belt winding body 155, the worker can prevent the weight of the sandbag 50 from being a load on the bottom panel 23 of the cage body 20, and can hold the sandbag 50 in a suspendable manner within the storage space of the cage body 20.

In this state, the rotation stop rod 157 is inserted through the through hole 155h of the sandbag belt winding body 155, and the rotation stop rod 157 is engaged with the lower surface of the horizontal frame member 152a and the upper surface of the horizontal frame member 152b of the fixed frame body 150.

As a result, as shown in FIG. 3, the sandbag 50 remains suspended from the fixed frame 150, and the weight of the sandbag 50 is not placed on the bottom panel 23 of the cage 120. In other words, the belt 52 of the sandbag 50 is entangled with the fixed frame 150 of the hanging member 130, so that the sandbag 50 can be held in a suspendable manner within the storage space of the cage 120.

In addition, by adjusting the amount of rotation of the sandbag belt winding body 155, the worker can freely change the distance between the fixed frame body 150 and the sandbag 50 when the sandbag 50 is suspended from the fixed frame body 150.

The suspending body 140 and the fixed frame body 150 are connected by a sling rope 40, so when the suspending body 140 is suspended by heavy machinery, the cage body 120 attached integrally to the fixed frame body 150 is also lifted at the same time. At this time, the sandbags 50 are lifted together with the cage body 120 via the sandbag belt winding body 155 of the fixed frame body 150 without coming into contact with the bottom panel 23 of the cage body 120.

As a result, when the futon basket 200 is suspended by heavy machinery, the weight load of the sandbags 50 is not placed on the cage body 120, and deformation of the cage body 120 due to the weight load of the sandbags 50 can be prevented in advance.

(1-3) Third embodiment The overall structure of the futon basket according to the third embodiment of the present invention will be described in detail below with reference to Fig. 7 and Fig. 8. Fig. 7 is a schematic perspective view showing the structure of the futon basket according to the third embodiment of the present invention. Fig. 8 is a front view and a plan view showing the structure of the hanging member of the futon basket according to the third embodiment of the present invention.

As shown in FIG. 7, in which parts corresponding to those in FIG. 3 are given the same reference numerals, the futon basket 300 in the third embodiment mainly comprises a cage body 120 having an overall rectangular parallelepiped shape, a hanging member 230 that is disposed above the cage body 120 and attached integrally to the cage body 120 when the futon basket 300 is suspended by heavy machinery (not shown), and a sling rope 40 that is used when the futon basket 300 is suspended by heavy machinery.

The cage body 120 is the same as that used in the futon cage 200 in the second embodiment, and for the sake of brevity, its description will be omitted here. In addition, the sling rope 40 used to suspend the futon cage 300 by heavy machinery is also the same as that used in the futon cage 100 in the first embodiment and the futon cage 200 in the second embodiment.

As shown in FIG. 8, the hanging member 230 has a fixed frame 150 and clamping bodies 170a, 170b that are attached along the horizontal frame members 152a, 152b of the fixed frame 150 and clamp the belt 52 of the sandbag 50 between the fixed frame 150. The fixed frame 150 is made up of vertical frame members 151a, 151b and horizontal frame members 152a, 152b, and does not have a sandbag belt winding body 155 like the hanging member 130 of the futon basket 200 in the second embodiment.

The clamping bodies 170a and 170b are made of steel, and for example, an approximately L-shaped angle steel can be used. However, this is not limited to this, and the clamping bodies 170a and 170b can be H-shaped steel, I-shaped steel, channel steel, etc. The clamping bodies 170a and 170b have the same length and height as the horizontal frame members 152a and 152b, and are attached in a state in which the flat portions of the clamping bodies 170a and 170b and the flat portions of the horizontal frame members 152a and 152b can be in close contact with each other through surface contact.

The clamping bodies 170a, 170b can be attached to the horizontal frame members 152a and 152b using bolts bt1 to bt4, and can be firmly connected to each other using bolts bt1 to bt4 while the belt 52 of the sandbag 50 is clamped.

In this case, the clamping bodies 170a and 170b can be connected at four points in total, two at each position spaced apart slightly larger than the width of the belt 52 of the sandbag 50, by bolts bt1 to bt4. The clamping bodies 170a and 170b are attached to restrict horizontal movement of the belt 52 of the sandbag 50 while it is clamped between the horizontal frame members 152a and 152b. Therefore, it is preferable that the flat surfaces of the clamping bodies 170a and 170b and the flat surfaces of the horizontal frame members 152a and 152b are formed with a surface roughness that increases frictional resistance.

In the above configuration, the futon basket 300 is constructed by storing two sandbags 50 inside the cage body 120, attaching the top panel 24, and storing the two sandbags 50 in the storage space of the cage body 120 and covering it with the top panel 24.

Next, the belt 52 of the sandbag 50 is pulled out from the gap between the multiple top panel members 24a of the top panel 24 and entangled so as to straddle both the horizontal frame members 152a and the horizontal frame members 152b from the outside. After that, the fixed frame body 150 of the hanging member 130 is attached and fixed integrally to the top panel 24.

Then, the clamping bodies 170a and 170b are attached to the horizontal frame members 152a and 152b. At this time, the clamping bodies 170a and 170b are firmly attached to the horizontal frame members 152a and 152b with the belt 52 of the sandbag 50 sandwiched between the clamping bodies 170a and 170b and the horizontal frame members 152a and 152b.

As a result, the belt 52 of the sandbag 50 is entangled with the horizontal frame members 152a, 152b of the fixed frame body 150, and the sandbag 50 and the cage body 120 are integrated with each other in a state in which the movement of the belt 52 to one end or the other end in the direction of the arrows cd is restricted by the clamping bodies 170a, 170b.

In this state, the futon basket 300 is made ready to be hoisted by heavy machinery by tying the sling rope 40 to the belts 52 of the two sandbags 50. When the sling rope 40 of the futon basket 300 is hoisted by heavy machinery, the belts 52 of the sandbags 50 are pulled up via the sling rope 40.

At this time, the sandbag 50 comes into contact with the top panel 24 of the cage 120, and the cage 120 is suspended together with the sandbag 50. In other words, when the belt 52 of the sandbag 50 is suspended via the sling rope 40, the cage 120 is simultaneously suspended with the sandbag 50 in contact with the top panel 24.

At this time, it is possible to create a situation in which the weight of the sandbag 50 is not loaded onto the bottom panel 23 of the cage 120. That is, when the belt 52 of the sandbag 50 is entangled with the fixed frame 150 of the hanging member 230 and the belt 52 is pulled up by heavy machinery via the sling rope 40, the sandbag 50 is held in a suspendable manner within the storage space of the cage 120.

Therefore, in the futon cage 300, the weight load of the sandbags 50 is not placed on the cage body 120 by directly suspending the belt 52 via the fixed frame body 150 using heavy machinery, so that the cage body 120 can be prevented from being deformed by the weight load of the sandbags 50.

In addition, in the futon cage 300, when the sling rope 40 is suspended at one point by heavy machinery, the belts 52 of the two sandbags 50 tend to move. However, because the belts 52 of the sandbags 50 are firmly clamped between the clamping bodies 170a, 170b and the horizontal frame members 152a, 152b, the position of the sandbags 50 contained in the cage body 120 does not change, and deformation of the cage body 120 can be prevented in advance.

2. Other embodiments Those skilled in the art can appropriately modify the futon baskets 100, 200, and 300 of the present invention in accordance with conventionally known knowledge. As long as the configuration of the present invention is still provided even after such modifications, they will of course be included in the scope of the present invention.
