Description

Buoyancy foothold

The present invention relates to a buoyancy scaffold.

In general, the footrest is a device that is installed to step on when moving up or down a place. The scaffold is installed in a place where the user is not high or walking. A place that cannot move refers to a place where a user cannot set foot, such as on the sea, swamp, or the air. In particular, the scaffold installed on the sea is installed in the vicinity of the farm can be carried out with the user located on the scaffold.

The scaffolding on the sea is installed between buoyant buoys. Scaffolding is connected to the mouth at both ends. Buoys have buoyancy floating in water and can be connected to nets located in the water. The floats are held in place by being anchored to the bottom of the sea or connected to heavy objects placed in the bottom. The mouthpiece consists of a foamed resin material obtained by foam molding a synthetic resin. The foamed resin material generates voids due to the gas introduced during the foaming of the synthetic resin. The foamed resin with voids thus generated has a buoyancy which can float on water. These foamed resins are buoyant due to internal voids and do not require a space for air storage. In addition, even if the foamed resin is partially damaged, there is an advantage that the buoyancy is generated in the remaining portion does not buried in the water.

However, the buoys fixed to the bottom or the weight of the sea are severely generated by the waves. Also, the floats flow irregularly due to the waves. The floats located at both ends of the scaffold may generate flow in different directions. Thus, when flow occurs in different directions, the scaffolds connected to the floats have different loads at both ends. The life of the scaffold is shortened by the load, and if the load is continuously applied, the scaffold is separated from the mouth, or the scaffold is easily broken.

In addition, the buoys made of foamed resin have voids inside, and are therefore susceptible to external impact. The floats connected at both ends of the scaffold reduce the flow range of the connected scaffold. The floats whose flow range is reduced by the scaffold collide with the waves. The amount of impact due to the impact on the waves is concentrated in the mouth, causing a shortened life. There was a problem in that a weak buoy is broken when a continuous wave and collision to the ball.

In addition, the buoys formed of the foamed resin floating in the sea is partially broken by the waves. The foamed resin has voids in the interior, so that the binding force between internal tissues is poor. As a result, the waves hitting the float side continuously erode the foamed resin having a weak binding force. Foamed resins that fall off by erosion pollute the sea. In addition, the erosion rich ball is reduced buoyancy. The footrest installed in the buoy with reduced buoyancy may suddenly settle under water with the user standing up. Accordingly, there is a high risk that a user may fall into the water.

In addition, the scaffold with both ends connected to the float does not float in itself. In other words, scaffolding cannot be installed without buoyancy buoys floating in water. Floating scaffolds can only be installed where two or more floats are installed. Therefore, the conventional scaffolding is limited in its use, as its installation position is limited.

The problem to be solved by the present invention is that a plurality of buoyancy body stronger than the foamed resin is arranged in the lower portion of the scaffold, the scaffold itself has a buoyancy can be installed in the position where the user wants to float in the water, the user desired buoyancy Accordingly, to provide a buoyancy scaffold that can adjust the amount of buoyancy body.

1 to 3, the buoyancy scaffold 100 according to an embodiment of the present invention includes a scaffold 110, a buoyancy portion 120, and a connecting portion 130.

The scaffold 110 has a plate shape capable of stepping on the foot. Scaffold 110 is a plate that the user can step on the foot to move.

The buoyancy portion 120 is disposed below the scaffold 110, and includes a buoyancy body 121 having a buoyancy, a support protrusion 123, a fixing member 125, and a coupling protrusion 127. The buoyancy body 121 is arranged in plurality in the lower portion of the scaffold (110). The buoyancy body 121 has an air layer 122 inside. The air layer 122 is filled with air. The buoyancy body 121 is manufactured in a state in which the air layer 122 is closed so that air filled therein does not flow out. The buoyancy body 121 has a buoyancy by having an air layer 122 therein. Therefore, the buoyancy body 121 itself becomes one buoyancy body. Buoyancy body 121 is arranged in a plurality, it is connected to the connecting portion 130.

The support protrusion 123 protrudes above the buoyancy body 121. The support protrusion 123 protrudes from both sides separated from each other on the upper portion of the buoyancy body 121. An insertion space 126 is formed between the support protrusions 123. The scaffold body 110 is inserted into the insertion space 126. Both outer sides of the scaffold 110 is in contact with the inner surface of the support protrusion 123, the scaffold 110 is inserted into the upper portion of the buoyancy body 121 is installed. At least one fixing hole 124 penetrates the support protrusion 123. The fixing hole 124 communicates with the side surface of the scaffold 110 located in the insertion space 126.

The buoyancy body 121 and the support protrusion 123 is integrally provided with an air layer 122 formed therein. The buoyancy body 121 and the support protrusion 123 is made of a synthetic resin.

The above-mentioned synthetic resins include polyethylene (LDPE & HDPE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polyester (PET), styrene acrylonitrile butadiene (ABS) resin and nylon ( PA) and a group selected by any one or a mixture of two or more thereof. That is, it may be selected and used from the above-described synthetic resin group according to the use purpose and the installation place of the float 100.

In addition, the synthetic resin may be a degradable plastic.

Synthetic resin is a kind of high molecular compound and does not rot. When an incorruptible resin is thrown into the ocean, it destroys the food chain of fish, algae, and seaweed. In addition, when the resin is embedded in the ground, polluting the soil by preventing smooth air communication. In order to solve this pollution problem, degradable plastics that have been decomposed in a natural state have been developed. Degradable plastics may be classified into biodegradable plastics that are decomposed into microorganisms and photodegradable plastics that are decomposed by ultraviolet rays. Therefore, after a predetermined period of time, the buoyancy body 121 having the air layer 122 and the support protrusion 123 are integrally manufactured with naturally degradable plastic, thereby minimizing environmental destruction after disposal.

In addition, the buoyancy body 121 and the support protrusion 123 integrally formed may be molded by blow molding. Accordingly, the blow molding is determined in the shape and size of the buoyancy body 121 and the support protrusion 123 are arranged in a plurality depending on the size of the scaffold 110 on the top. A blow molding machine that can be molded according to a predetermined shape and size is adopted, and a mold is installed accordingly. The inside of the provided mold is supplied with a synthetic resin heated to a temperature at which the shape can be deformed. After the synthetic resin is supplied, air is injected to form the air layer 122. When the air is injected, the heated synthetic resin is expanded to form the buoyancy body 121 and the support protrusion 123 having the air layer 122 formed therein by a mold. When the molding of the buoyancy body 121 and the support protrusion 123 is finished, the air layer 122 into which air is injected is closed. Accordingly, the buoyancy body 121 and the support protrusion 123 are integrally provided with an air layer 122 formed therein, and may be manufactured by blow molding.

In addition, the buoyancy body 121 and the support protrusion 123 may be made of an integral polyester (PET) having an air layer 122 therein by blow molding. That is, polyester which can be produced in a form most suitable for blow molding can be used as the synthetic resin.

In addition, the buoyancy body 121 and the support protrusion 123 is formed integrally with an air layer therein by blow molding, a mixture of polyester (PET) and aliphatic co-polymer (Aliphatic-Co-Polymer) and aliphatic poly It may be made of any one of an ester copolymer (PET- Aliphatic-Co-Polymer). Aliphatic copolymers are mixed with polyesters to increase cold resistance. The thermal properties of the polyester remain undeformed at temperatures from -60 ° C to + 150 ° C. However, in extreme climates and glacier topography, sea temperatures can drop below -60 ° C. Thus, in order to prevent deformation of the float 100, the aliphatic copolymer may be mixed with polyester, or the cold resistance strength may be increased by using a synthetic resin containing an aliphatic copolymer in the preparation of the polyester. Therefore, deformation of the float 100 due to the temperature decrease can be prevented and the life can be increased.

Here, in the present specification, for convenience of description, the buoyancy body 121 and the support protrusion 123 are molded integrally with the air layer 122 by blow molding.
