Description

The present invention relates to protective covers.

BACKGROUND ART Conventionally, there is a heat-insulating protective cover that is wrapped around a pipe to protect and insulate the pipe. Since such a heat insulating protective cover is generally rectangular in shape, it can be wrapped around straight pipes as it is, but cannot be wrapped around bent or curved pipes. I have a problem that I can't.

Here, although the field is different, there is a technology of a heat insulating cover for installing in a curved marine engine hot part. Specifically, in Japanese Patent Application Laid-Open No. 2015-83787 (Patent Document 1), a heat insulating cover for high-heat parts of a marine engine is formed by sewing into a three-dimensional shape corresponding to the outer shape of the high-heat parts of the marine engine. is disclosed. The molded heat insulating material of this cover consists of a layered heat insulating material in which an outer layer, a heat retaining layer, and an inner layer in contact with the high temperature part of the engine are laminated in this order. A tape is applied to the back side of the inner layer of the position, and the layered heat insulating material is sewn together with the tape with a sewing thread that melts at the surface temperature of the high temperature part of the marine engine. Since the heat insulating cover is sewn with the sewing thread that melts at the surface temperature of the high-heat portion of the marine engine, when the marine engine operates, the sewing thread melts at the surface temperature and the thickness of the heat insulating cover recovers. Therefore, the back side of the molded heat insulating material restrained by the sewing thread is brought into close contact with the high-heat part of the marine engine, and the heat insulating area against the surface of the marine engine and the thickness of the heat insulating cover are recovered, so that the heat insulating effect is remarkably improved. there is In addition, since the sewing tape is sewn along the inner surface of the molded heat insulating material, the heat insulating cover has an appropriate thickness, and the sewing tape spreads the heat insulating cover on both sides of the sewing line, so the heat insulating cover is not overstretched. It is said that a three-dimensional shape can be obtained, and moldability is greatly improved.

JP 2015-83787 A

When covering a bent or curved pipe with a heat insulating protective cover, cover the straight portion of the pipe with the heat insulating protective cover, and cover the bent or curved portion of the pipe with a portion of the heat insulating protective cover. I have to. In that case, there will be a portion that is not covered with the heat-insulating protective cover, and that portion will come into contact with the outside air, reducing the heat-insulating effect. Therefore, when covering the curved or bent portion of the pipe with the heat insulating protective cover, it is preferable to cover them integrally. On the other hand, since the protective cover for heat insulation is basically composed of a rectangular sheet, there is a problem that even if it is applied to the bent or curved portion of the pipe as it is, it cannot be covered integrally. In addition, there has been a demand for a protective cover that can be integrally wrapped around a bent portion or a curved portion of a pipe, without being limited to the use of heat insulation.

Here, the technique described in Patent Document 1 requires a special sewing thread, and has a problem that it is difficult to apply the technique to a heat-insulating protective cover composed of a rectangular sheet. In addition, there is a problem that it cannot be applied to piping that does not have a high-temperature portion, other than for heat insulation.

Therefore, the present invention was made to solve the above-mentioned problems, and although it has a simple configuration, it can be easily bent at any position and integrally covers even a pipe having a bent portion. The purpose is to provide a protective cover capable of

The protective cover according to the present invention includes a sheet, a first detachable member, a second detachable member, a first fold line, a second fold line, a third fold line, and a fourth fold line. A line and a sewing part are provided. The sheets are rectangular in shape. The first attachment/detachment member is provided along the longitudinal direction of the sheet on a plane at one end in the lateral direction of the sheet. The second detachable member is provided along the longitudinal direction of the sheet on the bottom surface of the other end in the short direction of the sheet, and is detachable from the first detachable member. The first folding line is provided along the width direction of the sheet with a predetermined length. A second fold line is located on the sheet at a predetermined distance along the longitudinal direction of the sheet from the first fold line and has a length equivalent to the length of the first fold line, It is provided along the lateral direction of the sheet. A third folding line is spaced from the first folding line along the longitudinal direction of the sheet and in a direction opposite to the second folding line in the sheet at a half interval of 1/2 of the interval. It is provided along the short side direction of the sheet at a position spaced apart from the sheet with a length equivalent to the length of the first folding line. A fourth fold line is spaced from the second fold line along the longitudinal direction of the sheet and in a direction opposite to the first fold line in the sheet at the half-spaced position, It is provided along the short side direction of the sheet with a length equivalent to the length of the first folding line. The sewing part folds the sheet in a three-fold state along the longitudinal direction of the sheet using the first crease line and the third crease line as crease lines, and folds the sheet along the longitudinal direction of the sheet. The sheet is folded in three along the longitudinal direction of the sheet with each of the fourth crease lines as creases, and the third crease line and the fourth crease line are in contact with each other. , along the longitudinal direction of the sheet, passing through the first folding line, the second folding line, the third folding line, and the fourth folding line and sewing.

The second detachable member 12 is provided along the longitudinal direction of the sheet 10 on the bottom surface (back surface) of the other end portion 10b of the sheet 10 in the short direction, and is detachable from the first detachable member 11 .

Here, the first attachment/detachment member 11 is a female surface fastener, and the second attachment/detachment member 12 is a male surface fastener. Both ends of the first detachable member 11 and the second detachable member 12 are sewn along the longitudinal direction of the sheet 10, for example.

Further, the first folding line 13 is provided along the lateral direction of the sheet 10 with a predetermined length L of the sheet 10, and the second folding line 14 is the first folding line of the sheet 10. It is provided along the lateral direction of the sheet 10 with a length L equivalent to the length L of the first folding line 13 at a position spaced apart from the folding line 13 along the longitudinal direction of the sheet 10 by a predetermined interval G1. .

Furthermore, the third folding line 15 is arranged along the longitudinal direction of the sheet 10 from the first folding line 13 in the sheet 10 and in the opposite direction to the second folding line 14, and is 1/2 the interval G1. is provided along the short side direction of the sheet 10 at a position spaced by a half interval G2 of , with a length L equivalent to the length L of the first folding line 13 .

It is provided along the short side direction of the sheet 10 at a position with a length L equivalent to the length L of the first folding line 13 .

Then, as shown in FIG. 2, the sewing part 17 folds the sheet 10 in three along the longitudinal direction of the sheet 10 with the first folding line 13 and the third folding line 15 as folding lines. At the same time, the sheet 10 is folded in three along the longitudinal direction of the sheet 10 using the second folding line 14 and the fourth folding line 16 as folding lines, and as shown in FIG. With the line 15 and the fourth folding line 16 in contact, the first folding line 13, the second folding line 14, the third folding line 15, and the fourth folding line 14 are arranged along the longitudinal direction of the sheet 10. It is constructed by passing through the folding line 16 and sewing.

As a result, with a simple configuration, it is possible to easily bend the pipe at any position and integrally cover even the bent portion of the pipe. That is, as shown in FIG. 3, of the bottom surface (back surface) of the sheet 10, the third crease line 15 and the fourth crease line 16 fixed by the sewn portion 17 are brought into contact with the bent portion of the pipe. When the second detachable member 12 is adhered to the first detachable member 11, as shown in FIGS. It becomes possible to bend it. As a result, the sewn portion 17 of the protective cover 1 can be used as a bent portion, and the pipe having the bent portion can be integrally covered with the protective cover 1 .

In addition, in order to form the curved portion of the protective cover 1, the first crease line 13, the second crease line 14, the third crease line 15, the fourth crease line 16, and the sewn portion 17 are formed into the sheet 10. Since it is only necessary to create the data, the configuration is extremely simple and can be easily implemented.

Due to the presence of the first crease line 13 and the third crease line 15, it can be easily folded into an inverted Z shape, and due to the presence of the second crease line 14 and the fourth crease line 16. , can be easily folded into a Z shape. After folding, the third fold line 13, the second fold line 14, the third fold line 15, and the fourth fold line 16 are positioned (interval G1 and half interval G2). Since the crease line 15 and the fourth crease line 16 are neatly brought into contact with each other, the sewn portion 17 can be easily formed.

Furthermore, since the first crease line 13, the second crease line 14, the third crease line 15, the fourth crease line 16, and the sewn portion 17 can be formed at arbitrary positions on the sheet 10, Even if the length of the sheet 10 in the longitudinal direction is increased, the positions of the first fold line 13, the second fold line 14, the third fold line 15, the fourth fold line 16, and the sewn portion 17 are adjusted. By changing, the tubular protective cover 1 can be freely bent.

For example, as shown in FIG. 7, a first folding line 13, a second folding line 14, a third folding line 15, a fourth folding line 16, and a sewing portion 17 are provided near the center of the sheet 10. In this case, of the cylindrical protective cover 1, the bent portion B (sewing portion 17) can be provided.

A first folding line 13, a second folding line 14, a third folding line 15, a fourth folding line 16, and a sewn portion 17 are formed in the vicinity of one end portion 10a of the sheet 10 in the lateral direction. is provided, the bent portion B of the cylindrical protective cover 1 can be provided on the side of the first detachable member 11 with respect to the adhesive portion A of the cylindrical protective cover 1 .

Further, a first crease line 13, a second crease line 14, a third crease line 15, a fourth crease line 16, and a sewn portion 17 are provided near the other end portion 10b of the sheet 10 in the lateral direction. is provided, the bent portion B of the cylindrical protective cover 1 can be provided on the side of the second detachable member 12 with respect to the adhesive portion A of the cylindrical protective cover 1 .

For example, as shown in FIG. 8, along the longitudinal direction of the sheet 10, a first folding line 13, a second folding line 14, a third folding line 15, a fourth folding line 16, and a sewn portion 17. are provided at various positions along the width direction of the sheet 10, the second detachable member 12 is adhered to the first detachable member 11, although attention is paid to the sewn portion 17 here. Then, the cylindrical protective cover 1 can be bent at various positions using the sewn portion 17 as a bending portion. In this way, since the protective cover 1 can be bent at various positions, even when the long pipe is bent at various positions, the protective cover 1 can be integrally covered and protected. Efficiency can be improved. For example, if the protective cover 1 is for heat insulation, it is possible to protect the piping having bent portions without lowering the heat insulation effect.

Here, the material of the sheet 10 is not particularly limited, but examples thereof include synthetic resin, rubber, and metal. The sheet 10 is preferably made of, for example, a material having high tensile strength and tear strength and flexibility. A tent fabric manufactured by adhering with etc. can be mentioned.
