Description

Sling cover {sling cover}

The present invention relates to a sling cover, and more particularly, to a sling cover with improved binding force and durability with an object.

In general, a protective material surrounding the outer surface of the object is used so that the object is protected from external environments such as rainwater when storing and transporting the object. Such a protective material was provided with a vinyl material to surround the outer surface of the object.

In recent years, the trend of reducing the use of vinyl and using a substitute to replace it in order to prevent environmental pollution problems continues in developed countries. Accordingly, research and development to reduce the amount of vinyl used for protective materials is being conducted in Korea, and research to develop a substitute thereof is required.

In addition, when the object is to be partially covered in order to prevent direct contact from rainwater or the like, a protective material is disposed surrounding the upper portion of the object and the side adjacent to the upper portion.

However, when the conventional vinyl protective material is covered on the upper and side surfaces of an object provided in a hexahedral shape, it is easily torn when caught by the sharp edge of the object, thereby reducing durability, and water tightness is deteriorated as moisture penetrates through the torn part. .

In addition, conventionally, there is a problem in that the storage safety of the object is deteriorated because the vinyl protective material covered with the object is easily separated from the object by strong wind during transport. At this time, a string or the like may be tied and fixed to fix the vinyl protective material on the outer surface of the object, but there is a problem that it is difficult to apply a method of tying the string or the like in the case of an object that is easily damaged.

As it is, since the inflow of wind is significantly reduced, the binding force with the object can be significantly increased.

Second, a plurality of perforated holes are penetrated in the form of a matrix in the side cover, and the wind flowing into the gap between the object and the watertight cover is quickly discharged through the perforated hole to prevent separation of the watertight cover, and rainwater is preset by surface tension. As it falls without penetrating into the perforated hole of the hole, it can provide a synergistic effect that improves the binding power and watertightness at the same time.

Third, as the margin extending in the transverse direction is formed on the top of the side cover with a predetermined length in the longitudinal direction, the margin covers the upper side of the side of the object through the elastic restoring force by the sling band, so moisture penetrates into the inside of the watertight cover. Is prevented in advance, and watertightness can be remarkably improved.

Fourth, the elastic rubber ring continuously wound along the transverse direction in the receiving space formed in the space between the lower part of the side cover folded toward the upper outer surface of the side cover based on a preset transverse line, and the side part of the object through the sling band Since the elastic restoring force surrounding the is formed double, the binding force between the watertight cover part and the object may be significantly increased.

Fifth, since the watertight coating layer of the watertight cover part is laminated as the molten resin is applied and hardened to cover at least one side of the woven layer including intersecting weft and warp, the weft and warp are firmly fixed to the external force. It can provide solid durability and watertightness at the same time by minimizing loosening and tearing.

It is a cross-sectional view.

1 to 6, the sling cover 100 according to an embodiment of the present invention is provided including a watertight cover part 20 and a sling band 30.

Here, the sling cover 100 is provided to cover the upper and side surfaces of the object 10 formed in a hexahedral shape. In this case, the object 10 may be provided in a rectangular or square cross-sectional shape with an upper surface of the object 10 so that four corners may be formed. In addition, the object 10 may be formed of a rubber material, but is not limited thereto. As such, the sling cover 100 covers the top and side surfaces of the object 10 so that the object 10 can be prevented from being contaminated by dust or the like.

Meanwhile, in the watertight cover part 20, it is preferable that the watertight coating layer 22 is laminated on at least one surface of the woven layer 21 woven by crossing the weft yarns 21a and 21b. At this time, the watertight cover part 20 may be provided as a waterproof sheet of polypropylene (PP) or polyethylene (PE) tarpaulin.

In detail, the weaving layer 21 is preferably formed as the weft yarns 21a and the warp yarns 21b having a predetermined width cross each other to be woven. At this time, the weft yarn 21a and the warp yarn 21b are preferably formed to have the same width, but in some cases, the weft yarn 21a and the warp yarn 21b may have different widths. .

Further, the weft yarn 21a and the warp yarn 21b are preferably made of an olefin-based resin material such as polyethylene or polypropylene, and may be made of polyvinyl chloride (PVC) in some cases. More preferably, the weft yarns 21a and warp yarns 21b may be formed of a polyethylene resin material.

Here, the polyethylene resin is a lightweight and inexpensive material, and it is economical because the manufacturing cost can be significantly reduced when manufacturing a product. In addition, it has excellent moisture-proof, cold-resistance, water-resistance, and electrical insulation, and has strong physical properties against acid/alkali and sunlight. Accordingly, even when exposed to the external environment, corrosion or deterioration/discoloration is prevented, so that the service life can be significantly increased and durability can be improved. In addition, since the permeation of air and moisture is restricted in the weft yarn 21a and the warp yarn 21b, moisture absorption in the object 10 can be prevented.

On the other hand, the watertight coating layer 22 is provided as a molten resin of substantially the same material as the woven layer 21 on at least one side of the woven layer 21 to cover the woven layer 21 and applied and cured. It is preferably laminated. In this case, a case where the watertight coating layer 22 is laminated on the upper surface of the woven layer 21 in an embodiment of the present invention will be illustrated and described as an example.

Here, the watertight coating layer 22 is laminated by coating and curing the molten resin of a material substantially the same as the material forming the woven layer 21 so as to cover at least one surface of the woven layer 21.

The watertight coating layer 22 is applied to integrally cover the weft yarns 21a and the warp yarns 21b intersected with each other, and the warp yarns 21a and the warp yarns 21b adjacent to each other. Through this, the weft yarn 21a and the warp yarn 21b are prevented from loosening due to external forces such as pulling, friction, and blowing by the wind. Therefore, since the weft yarn 21a and the warp yarn 21b are fixed, the durability of the product is improved and the service life can be significantly extended.

In addition, since the watertight coating layer 22 is formed of substantially the same material as the woven layer 21, fixing force due to a high degree of fusion between the same materials is improved. Therefore, since the watertight coating layer 22 is substantially prevented from being peeled off from the woven layer 21, durability and service life can be remarkably improved, and treatment for recycling is easy.

Therefore, the watertight coating layer 22 is laminated as the molten resin is applied and cured so as to cover at least one surface of the woven layer 21 including the weft yarn 21a and the warp 21b intersected with each other. Through this, the state in which the weft yarns 21a and the warp yarns 21b are woven is firmly fixed to minimize loosening and tearing by external force, thereby providing robust durability and watertightness at the same time.

On the other hand, the watertight cover part 20 is formed integrally with the top cover 20a provided with an area corresponding to the top surface of the object 10 and the top cover 20a, the outer side of the top cover 20a It includes a side cover (20b) extending downward from the rim. At this time, it is preferable to understand that the top cover 20a and the side cover 20b are integrally formed with each other so that the woven layer 21 and the watertight coating layer 22 are formed continuously.

In addition, it is preferable that the side cover 20b covers the upper side of each side portion of the object 10, respectively. Here, it is preferable that the top cover 20a is provided in an area corresponding to the top surface of the object 10 so that the side cover 20b is in close contact with each side portion of the object 10.

Here, the side cover 20b may be radially expanded in four places from each outer periphery of the upper cover 20a formed in a rectangular cross-sectional shape in the manufacturing step. That is, the unfolded shape of the watertight cover 20 before sewing may be formed in a cross shape. In addition, the outer edge of each width direction of the side cover 20b extended to four locations is sewn so that they can be connected to each other. Through this, the shape of the watertight cover part 20 may be formed into a hexahedral shape with an open lower side.

In addition, at each corner of the side cover 20b, an extra fold (not shown) may be formed to prevent tearing when elastic restoring force is generated in both sides in the transverse direction and to maintain the cover of the object 10. In this case, the clearance folded portion (not shown) is preferably formed integrally with the top cover 20a and the side cover 20b, and may be folded to be disposed inside each corner of the side cover 20b.

Here, when an elastic restoring force in the transverse direction is generated in the sling band 30 to be described later, the sling band 30 is elongated and the clearance folded portion (not shown) is unfolded, and each side portion of the object 10 I can cover it.

And, the upper portion (m) of the side cover (20b) is formed with a predetermined longitudinal length (y) to cover the upper side of the side portion of the object 10 in surface contact through the elastic restoring force of the sling band (30). It is preferable that the margin 23 extending along the transverse direction of the side cover 20b is formed. At the same time, it is preferable that the lower portion n of the side cover 20b is formed with a preset inner diameter, and a plurality of perforated holes 24 are formed in a matrix lattice shape along the longitudinal and transverse directions. In this case, the clearance part 23 is preferably understood as an area of the upper portion (m) of the side cover 20b in which the perforated hole 24 is not formed.

Here, the length (y) in the longitudinal direction of the margin 23 may be 30.0 to 100.0mm, most preferably 60.0mm. At this time, when the longitudinal length y of the clearance part 23 is less than 30.0mm, there is a concern that external moisture flows into the perforated hole 24 and penetrates into the upper surface of the object 10. In addition, when the longitudinal length (y) of the clearance part 23 exceeds 100.0mm, the watertight cover part 20 as wind flows into the gap between the object 10 and the watertight cover part 20 There is a concern that the is expanded and separated from the object 10.

Accordingly, as the clearance portion 23 extending along the transverse direction of the side cover 20b is formed at a predetermined length y in the upper portion m of the side cover 20b, the object 10 ) On the upper side of the side surface through the elastic restoring force of the sling band 30, so that moisture penetration into the inside of the watertight cover part 20 is prevented, so that watertightness can be remarkably improved.

In addition, the inner diameter (k) of the perforated hole 24 may be formed of 2.0 ~ 7.0mm, it is most preferably formed of 4.0mm. At this time, when the inner diameter (k) of the perforated hole 24 is less than 2.0mm, the wind flowing into the gap between the object 10 and the watertight cover part 20 quickly outside the perforated hole 24 There is a fear that the watertight cover part 20 is expanded and separated from the object 10 because it is not discharged into the air. In addition, when the inner diameter k of the perforated hole 24 is greater than 7.0 mm, there is a concern that external moisture is introduced through the perforated hole 24 to penetrate into the upper surface of the object 10.

Therefore, when the inner diameter (k) of the perforated hole 24 is formed to be 2.0 ~ 7.0mm, the wind flowing into the gap between the object 10 and the watertight cover part 20 passes through the perforated hole 24. Since it is rapidly discharged to the outside, expansion of the watertight cover part 20 by wind is prevented, so that separation from the object 10 can be prevented in advance.

Moreover, when the inner diameter k of the perforated hole 24 is formed to be 2.0 to 7.0 mm, moisture may fall without penetrating into the perforated hole 24 due to the surface tension of the water droplets. Through this, since penetration of external moisture into the upper surface of the object 10 is prevented in advance, watertightness can be remarkably improved.

Through this, in the lower portion n of the side cover 20b, a plurality of perforated holes 24 having a preset inner diameter are penetrated in a matrix grid shape along the longitudinal and transverse directions, so that the object 10 and the watertight cover part (20) The wind introduced into the gap is quickly discharged to the outside through the perforated hole (24). Therefore, it is prevented in advance that the watertight cover part 20 is separated from the object 10 by wind, and rainwater does not penetrate into the perforated hole 24 by the surface tension and falls as it is, so the binding force and watertightness are simultaneously It can provide a synergistic effect that is remarkably improved.

In addition, the distances d1 and d2 between each of the perforated holes 24 may be 30.0mm to 50.0mm, and most preferably 40.0mm. In this case, it is preferable that the lateral distance d1 and the longitudinal distance d2 between each of the perforated holes 24 are substantially equal to each other. Of course, in some cases, the lateral spacing d1 and the longitudinal spacing d2 between each of the perforated holes 24 may be formed differently in a grid.

On the other hand, the lower portion (n) of the side cover (20b) is folded toward the outer surface of the upper portion (m) of the side cover (20b) based on a preset transverse line (L), and the elastic restoring force of each of the sling bands (30) It is preferably fixed to the outer surface side of the upper (m) of the side cover (20b). That is, it is preferable that the lower end of the side cover 20b comes into contact with the outer surface of the upper portion m of the side cover 20b on which the clearance portion 23 is formed.

In addition, it is preferable that the sling band 30 is provided in plural and connected to each edge of the side cover 20b in a transverse direction, and provided to have a predetermined elastic restoring force. In this case, a case where the sling band 30 is formed on the inner surface of the side cover 20b in an embodiment of the present invention is illustrated and described as an example. Of course, the sling band 30 may be formed on the outer surface of the side cover 20b.

Here, the sling band 30 is formed on the inner surface of the side cover 20b, and the sling band 30 has a lower portion n of the side cover 20b based on a preset transverse line L As it is folded toward the outer surface of the upper portion (m) of the side cover 20b, it is preferable to be exposed to the outside of the watertight cover part 20.

In addition, each of the sling bands 30 is preferably disposed to be bent while surrounding the lower edge of each side portion of the side cover 20b. At this time, each of the sling bands 30 has one end connected to one side adjacent to the lower edge of the side cover 20b, and the other end connected to the other side adjacent to the lower edge of the side cover 20b. This is desirable.

Here, the sling band 30 is provided with a predetermined length, and both ends of the sling band 30 have the length of the sling band 30 to provide an elastic restoring force in the transverse direction to the side cover 20b. It is preferable to connect to one side and the other side of the side cover 20b of the excess area, respectively.

Accordingly, in the initial state before the sling band 30 is extended in the transverse direction of the side cover 20b, the side cover 20b is contracted in the transverse direction by the elastic restoring force of the sling band 30. The extra folded portion (not shown) may be formed. At this time, when the watertight cover part 20 is covered on the upper part of the object 10, as the side cover 20b and the sling band 30 are expanded in the transverse direction, the clearance folded part (not shown) is Can be extended.

In addition, the distance (x) between the sling band 30 and the lower end of the side cover 20b may be formed to be 25.0 to 35.0 mm, most preferably 30.0 mm. Through this, a phenomenon in which the side cover 20b is caught by the sling band 30 and is not unfolded while the operator covers the watertight cover part 20 on the top of the object 10 will be prevented in advance. I can.

Therefore, a plurality of sling bands 30 connected in the transverse direction so as to have a predetermined elastic restoration force at each corner of the side cover 20b of the watertight cover part 20 are elastic restoration force in the transverse direction of the side cover 20b By providing it, since tearing is prevented in advance, durability can be remarkably improved. At the same time, as the object 10 and the watertight cover part 20 are in close contact with each other through the elastic restoring force by the sling band 30, the air gap is minimized. Cohesion can be significantly increased. At this time, even when the wind in a speed range of 12 to 15 m/s is generated through a separate device for 30 to 60 minutes and is sprayed toward the object 10 for testing, the object 10 through the elastic restoring force by the sling band 30 ) And the watertight cover part 20 are in close contact with each other to minimize the voids, thereby preventing separation.

And, referring to Figure 6, when the lower portion (n) of the side cover (20b) is folded to the outer surface side of the upper portion (m) of the side cover (20b) based on a predetermined transverse line (L), the perforated hole ( 24) may be formed double on the upper (m) side and the lower (n) side of the side cover (20b).

On the other hand, a receiving space 41 is formed in the space between the lower portion n of the side cover 20b folded toward the outer surface of the upper portion m of the side cover 20b based on a preset transverse line L. This is desirable.

Here, the receiving space 41 may further include one elastic rubber ring 40 provided to have a predetermined elastic restoring force and continuously wound along the lateral direction of the side cover 20b. At this time, the elastic rubber ring 40 is provided in a ring shape, but is preferably provided with a length corresponding to the lateral circumference of the side cover 20b. In addition, the elastic rubber ring 40 is preferably disposed in the receiving space 41 along the predetermined transverse line (L).

An elastic rubber ring 40 provided to have a predetermined elastic restoration force and continuously wound along the transverse direction of the side cover 20b, and an elastic restoration force surrounding the side portion of the object 10 through the sling band 30 It is formed in double. Through this, separation by wind may be prevented, so that the binding force between the watertight cover part 20 and the object 10 may be significantly increased.

In addition, a junction part 42 may be stacked in the receiving space 41 so that a lower portion n of the folded side cover 20b and an upper portion m of the side cover 20b are bonded to each other. Here, the joint portion 42 may be applied and cured between the lower portion n of the folded side cover 20b and the upper portion m of the side cover 20b, which is provided as a curable resin. Alternatively, the joint portion 42 may be configured such that the lower portion n of the folded side cover 20b and the upper portion m of the side cover 20b are sewn together to be joined.

Therefore, since the lower portion (n) of the folded side cover (20b) and the upper portion (m) of the side cover (20b) are joined to each other through the joint portion 42, the elasticity disposed inside the receiving space 41 Since the separation of the rubber ring 40 is prevented, durability can be remarkably improved.
