Description

The present invention relates to a ring tree.

Rings are used to temporarily store materials such as building exterior wall panels and skeletons. Rings are also used when the goods to be transported are temporarily stored in a distribution warehouse. For example, a ring tree is laid on the ground or the floor of a distribution warehouse, and materials such as a plurality of outer wall panels and articles to be transported are stacked and stored on the ring.

Conventionally, wood molded into a square rod shape has been generally used as a ring. When the wood was used as a ring, the weight of the ring was large, and the installation and collection of the ring was complicated. Wood rings tend to absorb rainwater and become heavy, and the problem of weight tends to become more prominent. In addition, the wood ring is easily corroded, and there is a problem in terms of durability. In order to solve problems such as weight, a ring wood made of a synthetic resin material has been proposed.

For example, Patent Document 1 describes a ring made of a plastic molded product obtained by molding a strip-shaped member into a wavy shape. In this ring, it is said that the entire ring is uniformly cooled when it is formed by the concave portion of the wavy portion. Further, Patent Document 2 also describes a similar wavy ring tree. This ring is said to be composed of polyvinyl chloride, ABS resin, and the like.

The rings of Patent Document 1 and Patent Document 2 have a wavy shape. Therefore, although such a ring is lightweight, the wavy ring may be easily damaged depending on the direction in which the load is input.

When transporting materials stacked on a ring, for example, a forklift is used to transport the materials and articles. At this time, depending on the outer diameter of the forklift claw, the forklift claw may not enter between the ground and the material or the like. In such a case, it is necessary to separately prepare a large-sized ring tree in advance. However, transporting and managing a plurality of rings of different dimensions is cumbersome.

In addition, the ring may be too long depending on the size of the material and the place where the ring is installed. In such a case, it is necessary to separately prepare a short-sized ring tree in advance. However, transporting and managing multiple rings of different dimensions is cumbersome.

In view of the above problems, the present invention is lighter than a conventional ring made of wood, and it is possible to change the size of the gap between the material or the like placed on the ring and the ground. The purpose is to provide a ring that is possible and whose length can be easily changed in the field.

A ring wood composed of a top plate, a first side plate extending downward from one end of the top plate, and a second side plate extending downward from the other end of the top plate, and the top plate and the first side plate. The first side plate and the second side plate have a long hollow shape extending in the longitudinal direction, and a plurality of reinforcing plates extending along the lateral direction of the ring are intermittently arranged with respect to the longitudinal direction of the ring.

1 to 9 show an embodiment of a ring tree. The ring tree 1 of the present embodiment has a top plate 11, a first side plate 12 extending downward from one end of the top plate 11, and a second side plate 13 extending downward from the other end of the top plate 11. It is made of synthetic resin material. The top plate 11, the first side plate 12, and the second side plate 13 have a long hollow shape extending in the longitudinal direction. A plurality of reinforcing plates 14 extending along the lateral direction of the ring tree are arranged intermittently in the longitudinal direction of the ring tree 1. The length of the top plate 11 in the lateral direction is different from the length of the first side plate 12 in the lateral direction or the length of the second side plate 13 in the lateral direction.

The top plate, the first side plate, the second side plate, and the reinforcing plate are all plate-shaped made of a synthetic resin material. In the ring tree 1 of the present embodiment, the first side plate 12 and the second side plate 13 have a shape extending downward from both ends of the top plate 11 in the lateral direction, and the top plate 11 and the first side plate 12 or the second side plate 13 are formed. As shown in FIG. 5, the angle between the two is a substantially right angle.

One end of the first side plate 12 and the second side plate 13 has a shape connected to the end of the top plate 11. No bottom plate is arranged at the other ends of the first side plate 12 and the second side plate 13, and the shape is open. Therefore, when the ring tree 1 of the present embodiment is viewed from the bottom surface side, as shown in FIG. 2, the reinforcing plate 14 intermittently arranged with respect to the longitudinal direction of the ring tree 1 has a shape that can be visually recognized. It has become.

The reinforcing plate 14 is a plate-shaped member extending along the lateral direction of the ring tree 1. A plurality of reinforcing plates 14 are arranged. The reinforcing plates 14 are arranged intermittently with respect to the longitudinal direction of the ring 1 at predetermined intervals. In the ring tree 1 of the present embodiment, one end of the reinforcing plate 14 is connected along the lateral direction of the top plate 11, and the other end of the reinforcing plate 14 is a free end. In the ring tree 1 of the present embodiment, the reinforcing plate 14, the top plate 11, the first side plate 12, and the second side plate 13 are integrally molded of a synthetic resin material. Therefore, it does not take time and effort for molding, and it is possible to prevent a decrease in strength at the joint portion.

In the ring tree 1 of the present embodiment, the reinforcing plate 14 has a rectangular plate shape. The shape of the reinforcing plate is not limited to this, and can be changed according to the shapes of the top plate, the first side plate, and the second side plate.

In the ring tree 1 of the present embodiment, the length of the top plate 11 in the lateral direction is relative to the length of the first side plate 12 in the lateral direction or the length of the second side plate 13 in the lateral direction. It has different lengths. Specifically, as shown in FIG. 7, the length L1 of the top plate 11 in the lateral direction is the length L2 of the first side plate 12 in the lateral direction or the length of the second side plate 13 in the lateral direction. The shape is longer than that of L3.

For example, as shown in FIG. 8, when the first side plate 12 or the second side plate 13 of the ring tree 1 is placed so as to intersect the ground and the material 2 is placed on the top plate 11, the materials 2 are stacked. A gap having a length of L2 (L3) is formed between the materials 2. When transporting the material 2, a hand, a forklift claw, or the like is put in a gap of length L2 to transport the material 2.

When you want to keep the material 2 away from the floor or the ground due to circumstances such as when the floor or the ground is wet or dirty, or when it is difficult to insert the claw into the gap of the material 2 because the forklift's claws are thick. As shown in FIG. 9, it is preferable to place the material 2 on the top plate 11 so that the top plate 11 of the ring tree 1 intersects the ground. In this way, a gap having a length L1 having a larger interval than the length L2 (L3) is formed between the stacked materials 2. This makes it easier to move the material 2 further away from the floor or the ground and to insert the forklift claws into the gaps between the articles.

In the ring tree 1 of the present embodiment, the length L1 of the top plate 11 in the lateral direction is configured to be longer than the length L2 of the first side plate 12 or the length L3 of the second side plate 13. ing. The length L1 in the lateral direction of the top plate may be configured to be shorter than the length L2 of the first side plate or the length L3 of the second side plate. It is preferable that L2 and L3 have substantially the same length.

The value of L1 is not particularly limited, but can be, for example, 40 to 500 mm. The value of L2 or L3 is also not particularly limited, but may be, for example, 30 to 400 mm. The length of the ring tree 1 in the longitudinal direction is also not particularly limited, but may be, for example, 500 to 4000 mm. The length of the ring tree 1 in the lateral direction coincides with the length L1 of the top plate 11 in the lateral direction.

In the ring tree 1 of the present embodiment, since the reinforcing plate 14 has a shape arranged along the short side direction of the ring tree 1, the ring tree 1 is cut along the short side direction. The length of the can be easily adjusted at the site or in the warehouse. For example, the ring tree can be adjusted to about half at the site C in FIG. 3, and the ring tree 1 can be adjusted to about 4/5 at the site D in FIG. When cutting the ring tree 1, the portion where the reinforcing plate 14 is not provided may be cut. By doing so, only the top plate 11, the first side plate 12, and the second side plate 13 need to be cut, so that the cutting work can be easily completed. The reinforcing plate 13 is connected so as to intersect the top plate 11 substantially perpendicularly. Therefore, if the wheel tree 1 is cut vertically, the blade is less likely to interfere with the reinforcing plate 11.

As shown in FIGS. 5 and 6, in the ring tree 1 of the present embodiment, the end portion of the reinforcing plate 14 is joined to all of the top plate 11, the first side plate 12, and the second side plate 13. .. Therefore, as shown in FIG. 8, even when the first side plate 12 or the second side plate 13 of the ring tree 1 is placed so as to intersect the ground and the material 2 is placed on the top plate 11, the figure is also shown. As shown in 9, even when the top plate of the ring tree 1 is placed so as to intersect the ground and the material 2 is placed on the first side plate 12 or the second side plate 13, the reinforcing plate 14 of the article Can support the load. As a result, it is possible to prevent the ring tree 1 from being damaged by locally concentrating stress on any part of the ring tree when the article is placed.

In the ring tree 1 of the present embodiment, as shown in FIG. 5, the reinforcing plate 14 has a shape of being joined to the top plate 11 at its base end portion 141. The thickness of the base end portion 141 of the reinforcing plate 14 is larger than the plate thickness of the tip end portion 142 of the reinforcing plate 14. Since the reinforcing plate 14 has such a shape, when stress is applied to the ring tree 1, the reinforcing plate 14 of the ring tree 1 is less likely to be damaged because it breaks from the base end portion 141. It is said to be in shape.

In the ring tree 1 of the present embodiment, as shown in FIGS. 2 and 7, handles made of notches 15 are provided at both ends of the ring tree 1 in the longitudinal direction. In the example of FIG. 7, the shape of the notch is a substantially square notch in which the corner in the direction in which the top plate 11 is located is cut into an arc shape. Above the notch 15, a handle plate 16 extending downward from the end of the top plate 11 is arranged. When transporting, a finger can be inserted through the notch 15 to support the lower end of the handle plate 16 and the back surface thereof with the finger. As a result, the wheel tree 1 can be supported in a stable state. The handle plate 16 is composed of a substantially rectangular plate having a shorter length than the length L1 of the first side plate 12 or the length L2 of the second side plate 13. The shape of the notch is not limited to this, and may be, for example, an arc-shaped notch, a square notch, or a circular or square hole. Similarly, the shape of the plate for the handle is not limited to the above example.

The ring wood 1 of the present embodiment is composed of a mixture of wood chips and a synthetic resin material. As a result, the weight of the ring tree 1 can be reduced, and the strength can be improved as compared with the plastic alone. As the wood chips, for example, crushed wood branches, thinned wood, waste wood such as wood building materials, etc. can be used.

In the ring tree 1 of the above embodiment, the top plate is rectangular in plan view, and the first side plate or second side plate is rectangular in front view or back view. The shape of the top plate, the first side plate, or the second side plate is not limited to a rectangular shape, and may be, for example, an elliptical shape or a rectangular shape with arc-shaped corners.
