[Prior art]

 Conventionally, metal stanchions are used as stanchions for outdoor sports facilities such as soccer goal posts in soccer competitions, net fences in baseball fields, etc. In such a case, an athlete may be injured such as a bruise, or a ball may be damaged. Also on the pillar side, there is a problem that it is deformed by impact or the paint peels off and rust occurs. In order to deal with such a problem, a structure in which a sponge body is wound around a column is usually adopted. As an improvement of this, there is a device disclosed in Utility Model Registration No. 2524620. This invention has an elongated rubber body whose back surface is curved so that it can be mounted along the surface of a cylindrical column, and an extension portion extending in the width direction of this rubber body. A plurality of rows of protrusions are provided on the inner surface of the main body, and gaps are formed between these protrusions. In such a structure, when a force is applied to the surface of the rubber main body, the protrusion is compressed and a cushioning effect is obtained.

[0003]

[Problems to be solved by the device]

 In the protective device with the above structure, when the facility is left outdoors for a long period of time, since the protective device and the support are in close contact with each other, due to moisture such as raindrops entering between the support and the support, the support will be metal. In the case of manufacturing, there is a problem that the generation of rust is promoted and the life of the facility is extremely shortened. In addition, when the support columns are made of resin, there is a problem that mold and miscellaneous bacteria propagate due to accumulated water, resulting in unsanitary conditions. Even in the device disclosed in the above publication, although the gap is formed between the protrusions, the top of the protrusion itself is in contact with the column by the surface, and the extension portion and most other areas are in the column. Since they are in contact with each other on the other side, the water stays there and the generation of rust, mold and other bacteria cannot be prevented yet.

The present invention has been made in order to solve such a problem, and provides a protective device capable of minimizing the contact between the protective device and the support and minimizing the retention of water. Is.

[Means for Solving the Problems]

 The present invention provides a cushion layer that is installed to cover the outer periphery of a support pole for a sports facility where an athlete or a sports equipment such as a ball may collide, and a cushion layer that is formed on the inner surface side of the cushion layer to absorb and cushion the impact. A protective device comprising: a spacer forming a space between the cushion layer and a fastening member formed around the cushion layer parallel to the axial direction of the column, and fixing the cushion layer to the column. Has a substantially triangular prism shape, and a plurality of slanted prisms are formed on the inner surface side of the cushion layer at predetermined intervals, and the apexes of the triangular prisms are in linear contact with the surface of the pillar.

With such a structure, when an athlete or the like hits the protection device, the cushion layer, the space formed between the cushion layer and the column, and the spacer are crushed, and the impact is absorbed and alleviated. After the impact is released, the above parts return to their original shapes. Further, since the top of the spacer is linearly in contact with the surface of the support, the contact area between the protection device and the support is extremely small. Therefore, the amount of water retained in the contact portion is extremely small, and the drying thereof is quick. Further, since the contact line is inclined, the water that has entered between the cushion layer and the support column flows quickly downward, and there is no possibility of staying there.

Further, according to the present invention, the cushion layer is composed of an air bag hermetically sealed with air and a sponge body housed in the air bag. With such a structure, the impact is absorbed and absorbed by both the air sealed in the airbag and the sponge body. Further, even if the cushion layer gets wet with rain, there is no possibility that water will enter the airbag, so that the water is not absorbed by the sponge body, and the water is dried quickly.

Further, according to the present invention, the cushion layer is divided into three along the axial direction of the column, and a bent portion is formed at the divided portion, and the cushion layer is formed on each inner surface side of the three divided cushion layers. The spacers are arranged respectively. With such a structure, it is easy to mount on a pillar having a quadrangular cross section, and a ventilation hole is formed in the pillar axial direction between the divided cushion layers, so that the moisture can be dried more quickly. It is done calmly.

Further, the present invention is such that the cushion layer is formed of a sealed space formed by accommodating the sponge body by heat-sealing two air-impermeable flexible sheets. With such a structure, the cushion layer accommodating the sponge body can be easily formed.

[Embodiment of the invention]

 In FIGS. 1 and 2, reference numeral 1 denotes a protective device, which includes a cushion layer 2 and a spacer 3. The cushion layer 2 is divided into three parts, each of which is composed of independent cushion layer portions 2a, 2b and 2c. For this cushion layer 2, two sheets having air impermeability and flexibility, for example, a polyvinyl chloride sheet are stacked, and the entire circumference and the middle portion are heat-sealed by a welder to form three cushion layer portions 2a, 2b and 2c are formed. Each cushion layer portion 2a, 2b, 2c is composed of an air bag formed of the above-mentioned sheet and an elongated flat plate-shaped sponge body 4 accommodated in the air bag before fusion. Polyethylene foam can be used as the sponge body 4.

The spacer 3 has a triangular prism shape having a through hole, and a plurality of spacers 3 are adhered to the respective back surfaces of the cushion layer portions 2a, 2b, 2c at predetermined intervals and at an inclination. As a material for the spacer 3, a polyvinyl chloride resin having JIS A hardness of about 60 can be used. The spacers 3 that are adjacent to each other in the lateral direction are spaced at predetermined intervals by the divided portions of the cushion layer 2.

Numeral 5 is an eyelet made of brass or the like formed around the cushion layer 2 in the up-down direction (corresponding to the axial direction of the column) in the figure, and a plurality of eyelets are attached at predetermined intervals. The protective device 1 is fastened to the support column by passing a fastening member 6 (FIG. 4) such as a knot or a plastic fastener through the hole of the eyelet 5.

FIG. 3 shows a case where the protection device 1 is attached to the right and left columns 7 of the soccer goal post. The columns 7 are mainly made of metal such as iron or the like, or resin. The column 7 has a quadrangular cross section, and the cushion layer portions 2a, 2b and 2c are located on the front surface and the left and right side surfaces of the column 7, and the fastening member 6 is located on the rear surface, and the column is fastened.

As shown in FIGS. 4 and 5, when the protection device 1 is fixed to the column 7, the top of the spacer 3 linearly contacts the surface of the column 7. The spacer 3 is also deformed to some extent when the protection device 1 is fixed to the column 7, but this is not crushed and the linear contact is maintained. This contact line is inclined. Further, a ventilation hole 8 penetrating in the vertical direction is formed between the cushion layer portions 2a, 2b, 2c. Therefore, when raindrops or the like enter between the protection device 1 and the support column 7 from above, they flow along the support column contact portion of the inclined spacer 3 and flow down through the ventilation hole 8.

When a player such as a player or a ball hits the protection device 1, the cushion layer 2 and the spacer 3 are crushed and elastically deformed, and the impact is absorbed and relaxed. This protects the competitor from injury and also protects the stanchion 7 from damage such as paint peeling, deformation (if made of metal), cracking or breaking (if made of resin).
