DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for covering a covering, and more particularly, to a cover using a sheet which can be easily expanded and folded.

[0002]

2. Description of the Related Art Conventionally, various covers for covering a coating material have been known. Among them, a cover made of a sheet is light in weight and can be formed into a free shape. in use. Various materials are used to form the sheet, for example,
Resin materials such as polyethylene and polyvinyl chloride are used. To cover and cover the cover made of this sheet, cover the cover while spreading the cover with the edge of the folded cover fixed in place,
Alternatively, the cover may be spread, and then the spread cover may be placed on the covering. To remove the cover covering the cover from the cover and fold the cover, the cover may be covered with the cover in the reverse order. In both the case where the cover is put on the cover and the case where the cover is removed from the cover and folded, a plurality of persons are required when the cover has a certain size or more (for example, a rectangular shape of 4 m × 5 m). It requires extremely complicated work.

[0003]

Accordingly, in the present invention, a cover using a sheet is easily and quickly used both in a case where the cover is put on the cover and a case where the cover is removed from the cover and folded. The purpose is to provide a cover that can be made.

[0004]

In order to achieve the above object, in the cover of the present invention, a bone member is attached to the sheet so that the sheet can be folded at a predetermined position. In this way, the bone member gives a certain rigidity to the area of the sheet that is not folded, and a part of the area (one of the bone member) is used both when the cover is put on the covering and when the cover is removed from the covering and folded. The entire area can be successfully moved (spread or folded) by applying force to the part, and can be performed easily and quickly by one person. That is, the present invention provides a cover for covering a coating, wherein the bone member attached to the sheet reinforces each of the sheet and a plurality of regions of the sheet separated by a folding line crossing the sheet. Which is divided at the folding line,
And a bone member.

[0005] The cover of the present invention (hereinafter referred to as "book cover") is for covering a coating. The coating may be of any type, and examples thereof include machines, devices, land, and buildings. Since this cover can greatly facilitate the handling of the cover when it becomes larger than a certain size (it can be put on the cover and removed from the cover and folded), the cover of a certain size or more can be used. This cover is preferably used for objects. This cover can protect the covering from various things according to its material and strength, for example, rainwater,
Protect coatings from dust, snow, trash, earth and sand, gravel, mud, etc.

[0006] Recently, there is a case where it is necessary to avoid contamination by feces of cats. In this case, the present cover can be suitably used. In particular, cats often excrete in sandboxes used by children (eg, sandboxes located in kindergartens, parks, and nurseries), and there is a concern that the deterioration of sanitary conditions in sandboxes may affect children. ing. For this reason, a method of frequently covering the upper part of the sandbox with a cover so that the cat does not excrete the sandbox used by the children is often used, and the present cover can be suitably used as the cover used in the method. That is, a sandbox cover used by children is often handled by a weak woman (for example, a mother or a nursery mother) or by the children themselves, and the conventional cover was sometimes difficult to handle. However, by using this cover, it is possible to cover the sandbox or remove the cover from the sandbox and fold it very easily and quickly.

[0007] The cover has a sheet. The sheet may have any size, depending on the type, shape and size of the coating, what the sheet contacts, the load applied to the sheet, etc.
It may be formed by thickness, shape and material. The size of the sheet may be varied depending on the size of the covering. For example, when a rectangular sheet is used, the size may be as small as about 1 m × 1 m in width to several tens m in length × horizontal. It may be as large as about 10 m or more.
The thickness of the sheet may be various depending on the load or impact applied to the sheet, and may be, for example, as thin as about 0.01 mm to as thick as about 10 cm. The shape of the sheet may be varied depending on the shape of the covering, and may be, for example, a circle, a semicircle, a sector, an ellipse, a polygon (triangle, square (trapezoid, parallelogram (including rhombus))
And so on. ), Pentagon, hexagon, heptagon, octagon and the like. ) May be used. In particular, it is preferable to use a rectangular (including square) sheet because it can be easily used as a general-purpose cover. As the material for forming the sheet, it is preferable to use a material having a predetermined flexibility enough to fold the sheet. For example, a resin material (including a rubber material), a fiber material, a thin metal material, or the like is used. It is preferably formed. In addition, when covering a high-temperature coating material, a material having heat resistance may be used so that the sheet can withstand radiant heat or the like, and when oil adheres to the sheet, a material having oil resistance may be used. Good. When the load applied to the sheet is large, a reinforcing material such as a string may be woven into the sheet.

[0008] The cover has a bone member. The bone member is a bone member attached to the sheet that reinforces each of a plurality of regions of the sheet separated by a folding line that traverses the sheet and that is separated at the folding line. is there. The sheet is divided into a plurality of regions located on both sides of the fold line by a fold line passing through the sheet. The folding line may traverse the sheet at any position, but if the sheet is rectangular, it is preferable to provide a folding line parallel to the sides of the rectangle because folding is easy and storage is convenient. . Any number of folded lines may exist, and the number is one in the case of the least number, and there is no particular limitation in the number more (for example, two, three, four, five, etc.). If there are two or more fold lines,
The folding lines may or may not cross each other.

A bone member reinforces each area of the sheet delimited by the folding line. The bone members provide a certain rigidity (reinforcement) to each area by being attached to each area of the sheet, and it is possible to move each area collectively by applying a force to a part of each area I do. Since the bone member is divided at least at the folding line (since the bone member is not continuous on the left and right sides of the folding line), the rigidity of the bone member does not prevent the folding of the sheet at the folding line.
Therefore, the bone member gives each region rigidity for moving each region integrally, but does not make it difficult to fold the sheet along the folding line, so that the present cover is extremely easy to fold and spread along the folding line. And can be done quickly. The bone members located on both sides of the folding line may be connected via hinges. In this way, the bone member is rotatably connected around the hinge, so that the folding of the sheet at the folding line is not hindered, and the stress applied to the folding line portion is received by the hinge and the bone member, so the sheet having a low strength. Since no stress is applied directly to the cover, the breakage of the sheet can be prevented, and the durability of the cover can be improved. The structure of the bone member is not particularly limited as long as it can sufficiently reinforce the sheet.For example, in order to have a high reinforcing effect on the bone member, a parallel bone member and a folding line parallel to the folding line are used. It is preferable to have a structure having a vertical bone member perpendicular to the structure. It is more preferable that the parallel bone member and the vertical bone member are combined to form a ladder-like structure because a bone member having a higher reinforcing effect (for example, higher torsional rigidity) can be obtained.

It is preferable that the bone member has such a rigidity that the rigidity for moving the respective regions integrally is given to the respective regions. Therefore, bones are formed by steel materials (including stainless steel), metal materials such as aluminum, magnesium and titanium, and resin materials such as polyethylene, polypropylene, polyester, epoxy resin, polyurethane, silicon resin, vinyl chloride resin, polyacetal, polycarbonate and polyamide. The member is preferably formed. Further, if the present cover can be folded along the folding line and wound up in the direction of the folding line, the entire cover can be reduced in size, which is extremely convenient for storage when the cover is not used. For this reason, it is preferable that the bone member is flexible enough to allow the book cover to be folded along the folding line so as to be wound up in the direction of the folding line. Further, it is preferable that the bone member is formed of a metal material or a resin material having spring elasticity, because the folded cover can be easily expanded by the repulsive force of the bone member when the cover is expanded. From this point, it is preferable that the bone member is formed of, for example, a stainless steel sheet or polyester sheet having spring elasticity.

The attachment of the bone member to the sheet may be performed by any method as long as the bone member and the sheet can be attached with sufficient strength.
Bonding, sewing, embedding in a sheet, fusion of a bone member and a sheet, and the like can be performed. In particular, it is preferable to use the adhesive tape, the adhesive, and the sewing method because the bone member and the sheet can be securely and easily attached with high strength. The method of using the adhesive tape is such that even when the bone member and the sheet are attached by an adhesive tape having an adhesive portion on only one side, the bone tape is provided by interposing an adhesive tape having an adhesive portion on both sides between the bone member and the sheet. The member and the sheet may be attached. The bonding is performed by bonding the bone member and the sheet using an adhesive corresponding to the material of the bone member and the sheet. The sewing is performed by sewing the bone member to the sheet with a linear member such as a thread or a string.
