Description

  This device is mainly used for, for example, marine hawser ropes, tugboat ropes, marine ropes, and, if necessary, aquaculture fisheries ropes for aquaculture, stationary, bottom dredging, etc. The present invention relates to a guide guard used by applying to (hereinafter simply referred to as a rope in this device).

  From a marine terminology, the conductor is called a chock or a fairleader. Specifically, it is provided on the deck of a ship in order to guide, for example, when a tugboat rope or a ship hawser rope is fed or unloaded. The shape may be a ring shape (closed chock) or a C-shape (open chock) with the top open.

Conventionally, the portion of the rope that is in contact with each of the ropes of the ship is generally determined.
However, at these contact portions, the contact surface with these conductors is worn by friction. In particular, wear damage during the use of fiber cords is likely to occur at this site.

  Therefore, as shown in FIG. 14, these parts are devised so as to surround a protective material called a protector 1 ′ so as to reduce the wear of the rope and to extend the life of the rope as much as possible. . Specifically, a rectangular patch is wrapped around the rope.

  However, this type of protector 1 'that is wound around the conventional rope is generally made of a plain woven fabric of polyester fibers. In addition, it is necessary to set the attachment position of the protector 1 'to tie the rope piece (not shown) to the loop piece provided on the short piece of the rectangular protector, and to tie it to the rope with this, It was difficult to correctly contact the protector 1 'and the conductor. That is, at the start of the mooring operation, the protector 1 'is first attached to a required portion of the rope. However, in reality, the position where the cable is initially attached does not fit perfectly with the guide device due to the extension of the cable itself during the extension of the cable or during subsequent cable tension. As a result, the protector 1 'did not contact the conductor correctly, and it was necessary to adjust the attachment position of the protector 1' again. Therefore, as a result, much work and time are required for the mounting operation of the protector 1 '.

  Therefore, there is a demand for a means that does not require the trouble of attaching the protector to the cable-like shape, eliminates inadvertent friction with the conductor, and extends the cable-like service life.

In order to respond to this demand, the applicant of the present invention previously abandoned the method of attaching a protector in the form of a cable, and devised and proposed a new means (see Patent Document 1).
The concrete structure of the guard for a guiding device according to this proposal is that a reinforcing cloth member made of a high-performance fiber is integrally sewn on a base material made of a polyester-based synthetic fiber, and at least two opposite parts of the base material are opposed to each other. A guard piece is formed by integrally sewing a piece of a fixed string insertion portion forming cloth piece (loop piece) on the edge, and this is tied to a conductor with a tie string passed through the loop piece. Further, the depth width of the reinforcing cloth member is substantially the same as the depth width of the guiding device, and the lateral width is composed of one piece of a horizontally long rectangle formed substantially the same as the lateral width of the base material. In the center, the long side was sewn in parallel with the long side direction of the base material.

  However, since the rope insertion hole of the conductor has a circular shape or a curved surface of the letter C or U, the guard is stiff during the actual use of the structure proposed above. As a result, it was found that it was difficult to perform the desired functions. In addition, the bigger problem is that the reinforcing cloth member is a single rectangular piece having a width substantially the same as the depth of the conductor, and is sewn in the center of the depth of the base material. It will be located near the edge of the rope insertion hole of the conductor, and this sewing thread will come into contact with the rope and wear, and the end of the reinforcing cloth member will be rolled up and peeled off from the base material, resulting in the base material It is also possible that the cable will be worn and the cable may be worn by coming into direct contact with the conductor.

As a result of various studies on this phenomenon, it was found that the guard is a single piece of cloth for both the base material and the reinforcing cloth member, and they are overlapped and sewn together, so that the familiarity with the curved surface is not good.
As a result of various considerations based on this verification result, we came up with a structure that divides the base material in contact with the rope insertion hole of the conductor into multiple parts along the width direction, that is, the circumferential direction of the rope insertion hole. As a result of trials, it was found that there was no problem in practical use. As a result of further studies, a structure that can achieve the intended purpose successfully was finally obtained, and is proposed here.

  Therefore, the problem to be solved by the present invention is to improve the familiarity of the guard to the rope insertion hole of the guider as much as possible so that it can be securely attached over a long period of time without misalignment. It is.

  In order to solve the above technical problems, a guide guard according to claim 1 of the present invention includes a base material made of a polyester-based synthetic fiber and a high-performance fiber sewn integrally with the base material. A stringer guard composed of a reinforcing cloth member and a fixed string insertion portion forming cloth piece sewn integrally with the base material, wherein the base material is formed in a strip shape. Reinforced cloth members formed into a required shape by sewing a plurality of constituent fabric pieces with their long side edges attached to each other, and having the same size as that of the base material It is constructed by superposing on the base material and sewing together.

  The guard for a guiding device having the above-described structure is attached to the guiding device via a string, etc., with the base material side applied to the surface of the cable insertion hole of the guiding device, tied to the insertion portion forming piece of the fixed string. . Once the guard is attached, it will not be detached from the conductor unless the attachment string or the like is released. As a result, the surface of the conductor, particularly the surface of the cable insertion hole in contact with the cable shape, is always covered with this guard. Therefore, there is no direct contact between the conductor and the cable shape, and the risk of damage to the cable shape due to friction can be reduced. In addition, the base material is formed into a required shape by sewing a plurality of strips with their long side edges attached to each other, so that it is easy to bend at a small width like a bellows fold, leading to It comes in contact with the surface of the cord insertion hole of the vessel well.

  As described above, the conductor guard according to the first aspect of the present invention is not stiff like the conventional one, and at least the base material is bent with a small width like a bellows fold. It has become possible to prevent the possibility of misalignment for a long period of time by being familiar with the surface of the hole. Furthermore, since the reinforcing cloth member formed in substantially the same vertical and horizontal dimensions as the base material is superposed on the base material and integrally sewn, the frequency of the sewing thread of the reinforcing cloth member coming into contact with the rope is possible. As a result, the end of the reinforcing cloth member is less likely to be rolled up or peeled off from the base material, and the risk that the cord may directly contact the wearer and be worn away can be solved well. became.

  Moreover, since the conductor is surrounded by a guard using high-performance fibers, the wear of the rope can be reduced as much as possible. At the same time, unlike the conventional case, it is not necessary to attach or remove the protector to the cable. As a result, it is possible to extend and store the cords efficiently and easily, and greatly contribute to the improvement of work efficiency. In particular, due to the presence of high-function fibers, the useful life of the guard itself can be increased and the intended purpose can be achieved successfully.

Further, in this device, as described in claim 2, the reinforcing cloth member is a base material obtained by sewing a plurality of strip-shaped reinforcing band cloth base materials with their long side edges attached to each other. It is desirable that it is formed in the required shape matched.
This is because, as with the base material, there is no stiffness as with a single sheet, and it is possible to further adapt to the rope insertion hole of the conductor and prevent the position from shifting for a longer period of time.

From another point of view, the present invention can adopt a configuration in which the shape of the guard is rectangular or mountain-shaped as described in claims 3 to 4.
In the case of a rectangular shape, it is to be well tied to the main ridge-side cable with internal and external fixing hooks, etc., with fixed straps, etc., through the piece of cloth forming the fixed straps on both sides of the guard. Even if the tension direction of the rope is forward or backward, it can cover the entire inner circumference of the rope insertion hole of the rope, and the rope will be in direct contact with the rope and worn Fear can be resolved well.
In addition, the Yamagata has the following advantages. In other words, in general, the ropes installed at the bow have hooks to secure the rope on the deck side, but there are no facilities on the outer wall, so the guard must be fixed only on the deck side. . Therefore, if the guard has the same vertical dimension over the entire width, when it is attached to the conductor, the part located on the upper side of the guard may hang down by its own weight and block the rope insertion hole of the conductor. Will arise. However, according to this configuration, since the upper portion is a short side portion of the guard, even if the portion hangs down by its own weight, the risk of blocking the rope insertion hole of the conductor can be avoided well.

In addition, as described in claim 5, the base material constituting the base material piece and the reinforcing band member base material of the reinforcing cloth member are adjacent to each other at one side of each other. The edges of the base material constituting fabric pieces that are adjacent to each other are different from each other in the width direction of the guard so that they do not overlap with the edges that are attached together. It is desirable not to superimpose in the vertical direction on the side edges of the sides that are next to each other.
That is, the base material constituting cloth piece of the base material and the reinforcing belt cloth base material of the reinforcing cloth member are made to have different phases in the short side direction of each other, whereby the base material constituting cloth piece of the base material and the reinforcing band cloth of the reinforcing cloth member This is because it is possible to satisfactorily prevent the site of attachment of the long side with the base material from being vertically polymerized to form a weak point of strength.

In this device, the guard for the conductor is provided with a clearance for absorbing a dimensional difference between the inner side and the side edge of the conductor on the long sides opposite to each other. It is desirable that it is formed.
As for a conductor, the diameter of the inner side and the side periphery following it necessarily differs (refer FIG. 9). As a result, in order to absorb the difference in diameter between the inside and outside of the conductor, the guard is wrinkled toward the inside of the conductor. However, due to the existence of this allowance, the edge of the guard becomes substantially longer than the center side of the guard. Therefore, when attached, it is well adapted to the inner side and the side periphery, and can keep the cord-like slip well and prevent inadvertent cord-like wear.

Furthermore, as described in claims 7 to 9, it is desirable that the allowance is a ridge, a slit, or both.
By pulling the guard to the left and right, the two or one peripheral portions of the guard that are opposite to the peripheral portion of the conductor can be expanded laterally, and the length is longer than the length of the central portion (180 It is possible to match the lengths of two or one of the opposing edges of the guard well with the length of the side edge with respect to the side edge of the long conductor. As a result, even though there is a dimensional difference between the inner side, that is, the right and left inner side surfaces and the side rim of the conductor, the guard should be wound around the conductor correctly with the least possible occurrence of wrinkles. This is because it can be concluded.

Furthermore, in this device, as described in claim 10, it is desirable that the high-performance fiber is provided on either the front or back side of the guard, or on the front or back side, or mainly on the surface of the guard, at a site that abuts the streak.
From the viewpoint of increasing the strength of the guard, it is ideal to provide the entire area on the front or back surface. However, since high-performance fibers are expensive, it is desirable from the viewpoint of economic efficiency to reinforce the portions where the cords contact the guard. Also, in practice, the cable shape does not contact the entire circumference of the conductor (although depending on the position where the conductor is installed), in many cases the side from the inner peripheral surface of the conductor Since it is over the circumferential surface, it is desirable to provide it at this site, particularly at the site that contacts the inner circumferential surface.

  In addition, it is possible to select the front and back or both sides of the polyester-based synthetic fiber and assign the high-performance fiber to this, regardless of the type of abrasion that occurs due to the difference in the fibers used in the rope. This method is employed depending on whether the high-performance fiber should be brought into direct contact with the polyester-based synthetic fiber.

Furthermore, in this device, as described in claim 11, the fixed-string insertion portion forming cloth piece is formed by forming a strip-like cloth piece half-folded at both ends in the length direction and forming an eye. desirable.
Compared to a metal ring, it can be easily attached to the base material by sewing, and it can be used for many years without damaging the conductor and without any risk of corrosion. Because.

  Examples of the high-performance fiber employed include wholly aromatic polyamide fiber, wholly aromatic polyester fiber, polyparaphenylene benzobisoxazole fiber, polyvinyl alcohol fiber, and ultrahigh molecular weight polyethylene fiber. Among these, ultra high molecular weight polyethylene fibers are preferable.

  As the wholly aromatic polyamide fiber, a para-aramid fiber is suitable. As this para-aramid fiber, commercially available products such as (not shown for violation of public order and morals) can also be adopted.

  (Not published for violations of public order and morals)

  Moreover, the above highly functional fiber can be manufactured by a known method or a method equivalent thereto.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will now be described with reference to the drawings in which the conductor guard according to the present invention is applied to a conductor provided on the shore side and the bow, for example, a closed chock.

  Example 1 is the case where the guard for a conductor according to the present invention is applied to a closed chock, which is an example of a conductor, provided on the deck of a ship, and will be described based on the description of FIGS.

Various shapes are adopted for the guard 1 for a guiding device of the present invention depending on the closed chock C (see FIG. 9) to be applied. In this Example 1, as shown in FIGS. 1-4 and 6-8, it is a rectangular mat shape, and the ratio of length to width is formed about 1 to 1.3.
As shown in FIG. 1, the guard 1 basically has a rectangular base material 2 and a rectangular shape substantially the same size as the base material 2, which is integrally sewn on the surface of the base material 2. The reinforcing band member 3 is an example of the reinforcing cloth member, and the end portions are protruded outward from the long side edge 2A of the substrate 2 and the long side edge 3A of the reinforcing band 3, respectively. The long-side edges 2A and 3A are formed of fixed-string insertion portion-forming cloth pieces 4 that are integrally sewn at predetermined intervals in a direction along the edges.

  The base material 2 and the insertion part forming cloth piece 4 of the fixed string are formed of a general synthetic fiber, for example, a polyester synthetic fiber, and the base material 2 is formed in a rectangular mat shape. As shown in the figure, a sling belt having a narrow strip shape is employed. The reinforcing band 3 is obtained using a high-performance fiber, for example (not shown for violation of public order and morals) as a skin material, and a polyester-based synthetic fiber.

Furthermore, each structure is demonstrated concretely.
First, as shown in FIG. 3, the base material 2 is composed of a plurality of strip-shaped base material constituting cloth pieces 2B obtained from polyester synthetic fibers (in the example shown, the first sheet 2B1 to the sixth sheet 2B6). 6 sheets) are obtained by attaching the edges 5 on the long side (the side along the vertical direction: the direction along the vertical direction on the paper surface of FIG. 3) to each other to form a rectangle. The vertical and horizontal dimensions of the base material 2 disclosed in this example are as follows. The vertical direction is 1100 mm, the horizontal direction (the direction along the short side of the base material constituting fabric pieces 2B1 to 2B6: the horizontal direction on the paper surface of FIG. (Direction along) is formed to 1200 mm. Further, the width of each of the base material constituting cloth pieces 2B1 to 2B6 is approximately 1/6 of the horizontal width of the entire base material 2, and is formed to be 200 mm.

  As shown in FIG. 4, the reinforcing band fabric 3 includes a plurality of reinforcing band fabric bases 3B formed in a strip shape using polyester synthetic fibers made of the same material as the base material 2 (first sheet 3B1 in the illustrated example). -7th sheet 3B7) and as shown in the partial enlarged cross-sectional view of FIG. 5, each of the reinforcing band cloth base materials 3B1 to 3B7 is covered and folded back from the four periphery to the opposite side. It consists of a high-performance fiber sewn together at the edge, as an example (not shown for public order and morals violation), and a rope contact cloth piece 6 obtained from the material. The plurality of sheets 3B1 to 3B7 of the reinforcing band fabric base material 3B obtained in this way are obtained by attaching the long side edges 7 to each other and forming a rectangle. The vertical and horizontal dimensions of the reinforcing band cloth 3 disclosed in this example are 1100 mm in the vertical direction (direction along the long side of the reinforcing band cloth base material 3B: the vertical direction on the paper surface of FIG. 4), and the horizontal direction (reinforcing). The direction along the short side of the band base material 3B: the left-right direction on the paper surface of FIG. 4 is 1400 mm. In addition, the width of each of the reinforcing band fabric base materials 3A1 to 3A7 is about 1/7 of the width of the whole base material, and is formed to be 200 mm.

  Therefore, the size of the guard 1 itself is 1100 mm in the vertical direction and 1400 mm in the horizontal direction before being attached to the closed chock C. However, once attached to the closed chock C, as will be described in detail later, the end of the long side direction of the guard 1 can be expanded in the lateral width direction, and the lateral width of the guard 1 in this expanded state. Is provided with a special structure to be approximately 1580 mm to 1830 mm.

  As shown in FIG. 4, the fixed string insertion portion forming cloth piece 4 includes strip-like cloth pieces 4 </ b> A each having half-folds at both end portions in the lengthwise direction, each having an eye 8. Is configured to have a length that protrudes from the end on the long side of the guard 1 (: upper and lower ends on the paper surface of FIG. 4: 3A) to the outside by appropriate dimensions. Further, the insertion portion forming cloth piece 4 of the fixed string is arranged along the longitudinal direction of the reinforcing band cloth base material 3B, that is, the direction along the long side of the reinforcing band cloth base materials 3B1 to 3B7, In addition, the reinforcing band cloth base material 3B is overlapped on the reinforcing band cloth base material 3B at predetermined intervals in the lateral direction of the reinforcing band cloth base material 3B, that is, along the short sides of the reinforcing band cloth base materials 3B1 to 3B7. The reinforcing band fabric base material 3B is sewn together. In the drawing, the reinforcing band fabric bases at the left and right ends, that is, the first sheet 3B1 and the seventh sheet 3B7 are along the outermost edge, the second sheet 3B2 and the sixth sheet 3B6 are the center, and further 3 The 6th sheet 3B3 and the 5th sheet 3B5 are sewn together integrally to the reinforcing band fabric base material 3B as indicated by the sewing sewing line 9 along the innermost edge.

The base material 2 and the reinforcing belt cloth 3 as described above are sewn together as follows.
That is, as shown in FIG. 1 and FIG. 4, the center part of each short side direction of the base material constituting cloth pieces BA1 to 2B6 of the base material 2 is on the long side of the reinforcing band base materials 3B1 to 3B7. It superimposes on this reinforcement band cloth 3 so that it may be located on the attachment part of the edge 5. FIG. Next, the base material 2, the fixed string insertion part forming cloth piece 4 and the reinforcing band cloth 3 are each 1/5 from the central part in the long side direction of the base material 2 and both edges 5 (upper and lower ends on the drawing in the figure). It is attached to each of the three places, one at the center, in a single horizontal form. As a result, the base material 2, the reinforcing band cloth 3, and the fixed string insertion portion forming cloth piece 4 are sewn together. In FIGS. 3 and 4, 9A indicates a planned sewing line before sewing.

  Accordingly, at this stage, both long edges 2A of the base material components 2B1 to 2B6 of the base material 2 and both long sides of the reinforcing belt cloth base materials 3B1 to 3B7 of the reinforcing belt cloth 3 are provided. In the region from the edge 3A to the sewing line 9 at a location that is 1/5 each closer to the center, the edges 5 and 7 on the long side are free ends.

Next, the important point is the peculiarity of the sewing method after the heel.
As shown in FIG. 9, since the closed chock C has a diameter d of the side peripheral edge C4 larger than a diameter D of the left and right inner side faces C3 of the inner peripheral face C2 of the rope insertion hole C1, The configuration adapted to the difference in diameter allows the guard 1 to be wrapped around the closed chock C more accurately without any wrinkles and fastened, and the rope R as an example of the rope is further extended and retracted. It can be done smoothly.

In order to satisfy this requirement, in the present invention, as shown in FIGS. 1 to 4 and 6 to 8, two opposing edges on the long side of the guard 1, that is, the base material 2 and the reinforcing cloth The two margins 2A, 3A on the long side of the piece 3 are provided on the inner side of the closed chock C, that is, in the allowance 10 of two different forms for absorbing the dimensional difference between the left and right inner side surfaces C3 and the side peripheral edge C4. Is adopted.
One of the allowances 10 is a ridge 11 and the other is a slit 12.

As shown in FIGS. 1, 2, 4, 6 and mainly FIG. 6, the ridge 11 is formed by the left and right sides 2 </ b> B <b> 1, 2 </ b> B <b> 6 of the base material constituting fabric pieces 2 </ b> B <b> 1 to 2 </ b> B <b> 6 and the pair 2 </ b> B <b> 2, 2 </ b> B5 inside thereof. It is.
That is, the left and right sides of the free end portions of each of the base material constituting cloth pieces 2B1, 2B2, 2B5, 2B6, that is, the length of the outer portion from the upper and lower sewing sewing lines 9 (or the planned sewing line 9A). Each of the left and right side edges 13 on the side is sequentially drawn toward the free end so as to draw a partial arc on the side edge 7 on the long side of the corresponding reinforcing band base material 3B. Sewing to material 3B. More specifically, the first, second, fifth, and sixth base material constituting cloth pieces 2B1, 2B2, 2B5, and 2B6 correspond to the first reinforcing band cloth base material 3B1. The second reinforcing band base material 3B2, the third reinforcing band base material 3B3, the fifth reinforcing band base material 3B5, the sixth reinforcing band base material 3B6, and the seventh sheet This reinforcing band corresponds to each of the left and right side edges 13 on the long side of the outer part from the sewing sewing line 9 to the long side edge 7 of the reinforcing band cloth base material 3B7 attached to each other. The cloth base material 3B is sewn on the reinforcing band cloth base material 3B as indicated by a sewing sewing line 9 so as to draw a partial arc in order toward the edge 7 on the long side of the cloth base material 3B. In this way, at the left and right central portions of the four base material constituting cloth pieces 2B1, 2B2, 2B5, and 2B6 of the first, second, fifth, and sixth sheets from the sewing sewing line 9 respectively. A ridge 11 that rises in a mountain shape that becomes higher at the free end side is formed.

  When the guard 1 is pulled left and right, as shown in FIGS. 7 and 8, the collar 11 is flattened from the chevron and has two peripheral edges (long sides) opposite to the peripheral edge of the Claude Chock of the guard 1. The side edges 2A, 3A) expand laterally, and the length S can be longer (about 180 to 430 mm) than the length S1 of the part sewn in a rectangle on the center side. The lengths of the two opposite peripheral edges (long side edges 2A, 3A) of the substrate 2 can be matched to the length of the side peripheral edge C4. As a result, although there is a dimensional difference between the inner side, that is, the left and right inner side surfaces C3 and the side peripheral edge C4, as shown in FIG. It can be wrapped around the closed chock C and fastened.

Next, the slit 12 which is another structure of the clearance allowance 10 is demonstrated.
As shown in FIGS. 1, 4, and 6, two base material constituting cloth pieces 2 </ b> B <b> 3 and 2 </ b> B <b> 4 that overlap with the fourth reinforcing band base material 3 </ b> B <b> 4 in half in the width direction. The left and right sides of the fourth reinforcing belt base material 3B4 corresponding to the fourth reinforcing band fabric 3B4 corresponding to the long edge portions 13A on the outer side of the sewing sewing line 9 are gradually moved toward the free end. As shown by the sewing sewing line 9, a partial arc is drawn on each of the long side edges 7. And the edge part 13B on the opposite side to the edge part 13A on the long side of the two base material constituting cloth pieces 2B3 and 2B4 on the third sheet and the fourth sheet is the reinforcing band cloth. It is a free end without sewing to the base material 3B.

  Accordingly, the fourth reinforcing belt base material 3B4 is not integrated with the third and fifth reinforcing belt base materials 3B3 and 3B5, but on the long side where they are attached to each other. Freely independent of the third and fifth reinforcing band base materials 3B3 and 3B5, which are adjacent to each other on the long side edge portion 14 on the side of the long side that is outside the sewing sewing line 9 at the side edge. 2, 4 and 6, mainly as shown in FIG. 6, a slit 12 is formed between the fourth sheet and the third and fifth sheets adjacent to each other. Thus, by providing the slit 12, the outer edge 13B in the left-right direction of each of the third piece 2B3 and the fourth piece 2B4 of the base material constituting cloth pieces and the fourth piece of the reinforcing band cloth base material. When the left and right edges 14 of 3A4 become free ends and the guard 1 is expanded as shown in FIGS. 7 and 8, the guard 1 can be expanded further than the ridge 11, and the generation of folds is reduced as much as possible. Then, it can be wrapped around the closed chock C more accurately and fastened.

  The conductor guard 1 configured as described above is wound around a portion where the rope R is in contact with the closed chock C and fastened. More specifically, as shown in FIG. 10, the inner peripheral surface of the rope insertion hole C1 of the closed chock C, the insertion hole bottom C2, the left and right inner peripheral surfaces C3 connected thereto, and the insertion hole bottom C2 And it is wound around the side periphery C4 which continues in front and behind the left-right inner peripheral surface C3, and is fastened. The fastening is performed in such a manner that the fixed string 15 is sequentially tied up to the eye 8 of the fixed string insertion part forming cloth piece 4 through the fixed string 15.

  Therefore, the rope R always contacts the guard 1 and does not contact the closed chock C directly. As a result, the wear of the rope R can be reduced as much as possible. In addition, since the guard 1 comes into contact with the closed chock C via the reinforcing band 3 made of high-performance fiber, it is pressed against the closed chock C with a high pressure, and even by frictional contact with the closed chock C, The service life of the guard 1 can be significantly increased without being worn out. Furthermore, in the case of this example, since the compatibility between the rope R and the base material 2 is good, the wear of the rope R can be reduced as much as possible.

  In addition, a plurality of sheets in which the base material 2 and the reinforcing belt cloth 3 are each formed into a strip shape are attached to the long edges 5 and 7, respectively, and the base material constituting cloth piece 2B of the base material 2 The reinforcing band cloth base material 3B of the reinforcing band cloth 3 is formed in a rectangular shape by being polymerized by making phases different from each other in the short side direction, and is bent in a small width like a bellows fold. It is easy to adjust the diameter d of the side edge C4 well, and it can be wound more accurately without wrinkles. Furthermore, since the base part constituting cloth piece 2B of the base material 2 and the reinforcing belt cloth base material 3B of the reinforcing belt cloth 3 are not integrally wrapped with each other, the phases are different from each other, so that they are integrally sewn. It is possible to successfully prevent the occurrence of a weak point of strength, and it can be used safely for a long time.

  Further, the guard 1 is provided with a clearance 10 composed of a collar 11 and a slit 12, and the collar 11 is extended, and the slit 12 is expanded so that the side edge C4 of the closed chock C having a long dimension is expanded. The lengths of the two opposite edges of the guard 1 (the edges 2A and 3A on the long side) can be matched to the length of the side edge C4. As a result, despite the dimensional difference between the inner side, that is, the left and right inner side surfaces C3 and the side peripheral edge C4, the guard 1 is appropriately wound around the closed chock C with the least possible occurrence of wrinkles. Can be concluded. Therefore, the rope R can be drawn out and drawn in very smoothly, and the rope-like slip can be kept good and inadvertent rope-like wear can be prevented.

  Further, the rope R is always in contact with the guard 1 and is not in direct contact with the closed chock C, so that the wear of the rope R can be reduced as much as possible, and the guard 1 is reinforced with high-performance fibers. In order to come into contact with the closed chock C via the band cloth 3, the closed chock C is pressed at a high pressure and is not easily worn by frictional contact with the closed chock C. Needless to say, it can be much longer.

  In the above embodiment, it goes without saying that it can be applied to an open chop and a fair leader instead of a closed chock.

  The position where the reinforcing band cloth 3 is provided cannot be determined unconditionally depending on the difference in the fibers of the rope R used, and the size and structure of the closed chock C. However, basically, it is desirable from the viewpoint of economic efficiency to reinforce mainly the part where the base material 2 substantially contacts the closed chock C or the part where the rope R contacts the base material 2. In practice, the rope R does not contact the entire circumference of the closed chock C, but it depends on the position where the closed chock C is provided. For this reason, it is desirable to provide this portion, particularly a portion that contacts the inner peripheral surface. At a minimum, it is desirable to provide a width that is about one third of the width of the substrate 2.

Example 2 is a case where the guard for a guiding device according to the present invention is applied to a closed chock provided at the deck bow portion of a ship, and will be described based on the description of FIGS.
The same members and configurations as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIGS. 11 to 12, the second embodiment is characterized in that the overall shape in plan view is a mountain shape with a long central portion and short left and right sides.

  First, as shown in FIG. 11, the base material 2 is composed of a plurality of strip-shaped base material constituting cloth pieces 2B obtained from polyester synthetic fibers (in the example shown, the first sheet 2B1 to the fifth sheet 2B5). 5 sheets) are obtained by attaching the edges 5 on the long side (the side along the vertical direction: the direction along the vertical direction on the paper surface of FIG. 11) to each other. Specifically, it is composed of three strip-shaped sheets 2B2 to 2B4 disposed in the central portion and a pair of side base material constituting cloth pieces 2B10 and 2B50 disposed on the left and right sides thereof. The side base material constituting cloth pieces 2B10 and 2B50 disclosed in this embodiment are substantially half the length of the long side of the base part constituting cloth pieces 2B20 to 2B40 in the central portion in the longitudinal direction, and the central portion in the lateral direction. It is formed to have a width approximately twice as large as that of one base material constituting cloth piece 2B20-40. Further, the vertical and horizontal dimensions of the vertical base material 2 are as follows. First, in the longitudinal direction, the long central portion is 750 mm, the short side is 450 mm, and the lateral width is 1400 mm. Further, the width of each of the other base material constituting cloth pieces 2B2 to 2B4 except for the left and right sides is 1/7 of the width of the entire guard 1 and is formed to be 200 mm. Further, the left and right side portions are approximately one third of the entire guard 1 and are formed to be 400 mm. Accordingly, the lateral width of the central portion is 600 mm, and the lateral width of the side portion is 400 mm. And it forms so that it may become a mountain shape by planar view shape by aligning the one side of the vertical direction (lower side edge 2A in the figure) in a horizontal straight line.

As shown in FIG. 12, the reinforcing band fabric 3 includes a plurality of reinforcing band fabric base materials 3 </ b> B formed in a strip shape using polyester synthetic fibers of the same material as the base material 2 (first sheet 3 </ b> B <b> 10 in the illustrated example). 8 sheets of 8th sheet 3B80) and high-performance fibers that are sewn together to cover the surface of each of the reinforcing band fabric bases 3B10 to 3B80, as an example (not shown for violation of public order and morals) It is comprised from the obtained rope contact cloth piece 6. FIG. The plurality of sheets 3B10 to 3B80 of the reinforced band fabric base material 3B obtained in this way are each provided with the edge 7 on the long side (the side along the vertical direction: the direction along the vertical direction on the paper surface of FIG. 12). Obtained by associating each other. Specifically, it is composed of four strips 3B30 to 3B60 arranged in the central portion, and a pair of side reinforcing belt bases 3B10 to 20 and 3B70 to 80 arranged on the left and right sides thereof. . The side reinforcing band cloth base materials 3B10 to 20 and 3B70 to 80 disclosed in this embodiment are approximately two-thirds of the length of the long side of the reinforcing band cloth base materials 3B30 to 3B60 in the center portion in the longitudinal direction. In the lateral direction, the outermost pair 3B10, 3B80 is formed to have a width approximately half the width of one reinforcing band base material 3B on the center side, and one inner side is formed to be the same size as the reinforcing band base material 3B of the central part. . Further, the vertical and horizontal dimensions of the vertical base material 2 are as follows. First, in the longitudinal direction, the central part has a long portion of 950 mm, the side portion has a length of 650 mm, and the lateral width is also 1400 mm. Moreover, the width of each of the other reinforcing band base materials 3B20 to 3B70 except for the pair on the left and right sides is 1/7 of the width of the entire guard 1, and is formed to be 200 mm. Furthermore, the pair of the left and right sides is one-fourth of the entire guard 1 and is formed to be 100 mm. And it forms so that it may become a mountain shape by planar view shape by aligning the one side of the vertical direction (lower side edge 3A in the example) in a horizontal straight line. In addition, the longitudinal dimension is configured to be 200 mm longer than the base material constituting piece 2B in both the central portion and the side portion. Specifically, the upper and lower edges 2 </ b> A of the base material 2 are arranged 100 mm from the upper and lower edges 3 </ b> A of the reinforcing band 3, respectively.
In addition, a fixed string insertion portion forming cloth piece 4 is integrally sewn to a portion of 100 mm below the reinforcing cloth piece 3 at predetermined intervals in the width direction.
The fixed string insertion portion forming cloth piece 4 is made of the same material as in the first embodiment.

  Then, as shown in FIG. 11, the base material constituting cloth piece 2B of the base material 2 and the reinforcing cloth portion cloth base material 3B of the reinforcing band fabric 3 are integrated by being polymerized with different half pitch phases in the short side directions. It is formed by sewing.

  Further, within the range in which the base material constituting cloth piece 2B is set back, that is, in the range of 100 mm, the edge 7 on the long side of the reinforcing cloth portion cloth base material 3B is a free end and the slit 12 is formed. The

  According to the configuration shown in the second embodiment, as shown in FIG. 13, the mountain-shaped top side of the closed chock C provided in the bow portion of the deck is placed in a horizontal straight line with the top side of the mountain shape outside the ship. Place the base 2 side against the surface of the rope insertion hole C1 of the closed chock C with the edge sides 2A and 3A facing the inside of the ship (the deck side), and tie them to the eye 8 of the insertion part forming piece 4 of the fixed string. The guard 1 is attached to the closed chock C through the like. The guard 1 once attached will not be detached from the closed chock C unless the attachment string or the like is released. As a result, the closed chock C, particularly the surface of the rope insertion hole C1 in contact with the cord shape, is always covered with the guard 1. Therefore, there is no direct contact between the closed chock C and the cable shape, and the risk of damage to the cable shape due to friction can be reduced. In addition, a plurality of sheets in which the base material 2 and the reinforcing band cloth 3 are each formed into a rectangular shape are sewn together with the long edges 5 and 7 attached to each other to form a rectangular shape. Therefore, it is easy to bend with a small width like a bellows fold, and it can be well adapted to the diameter d of the side periphery C4 and can be wound more accurately without wrinkles.

By the way, it should be noted that the attachment is such that the long central portion of the guard 1 is located on the lower surface side in the insertion hole C1 that becomes the contact surface of the rope of the closed chock C.
In general, the closed chock C provided at the bow has hooks to secure the rope on the deck side, but since there are no facilities on the outer wall, the guard 1 must be fixed only on the deck side with a loop. Absent. Therefore, if the guard 1 has the same vertical dimension over the entire width, when the guard 1 is attached to the closed chock C, the portion located above the guard 1 hangs down by its own weight and closes the rope insertion hole C1 of the closed chock C. There is a risk that it will end up.
However, according to the configuration of the second embodiment, since the upper side is the short side portion of the guard 1, even if the portion hangs down by its own weight, the rope insertion hole C1 of the closed chock C may be blocked. Can be avoided successfully.

  In addition, as in Example 1, the base material constituting cloth piece 2B of the base material 2 and the reinforcing cloth portion cloth base material 3B of the reinforcing band cloth 3 are polymerized with different phases in the direction of the short sides of each other and integrally sewn. Since it is worn and formed in a rectangular shape, it is easy to bend with a small width like a bellows fold, and it can be well adapted to the diameter d of the side edge C4 of the closed chock C and can be wound more accurately without wrinkles. Can do. Furthermore, since the base part constituting cloth piece 2B of the base material 2 and the reinforcing belt cloth base material 3B of the reinforcing belt cloth 3 are not integrally wrapped with each other, the phases are different from each other, so that they are integrally sewn. It is possible to successfully prevent the occurrence of a weak point of strength, and it can be used safely for a long time.

  Further, the guard 1 is provided with a clearance 10 composed of a slit 12, and the slit 12 expands so that the side edge C4 of the closed chock C having a long dimension with respect to the side edge C4 of the guard 1 is at least on the deck side. The length of the long side edges 2A and 3A can be matched well with the length of the side edge C4. As a result, despite the dimensional difference between the inner side, that is, the left and right inner side surfaces C3 and the side peripheral edge C4 of the closed chock C, the guard 1 is reduced as much as possible to reduce wrinkles as much as possible. It can be wrapped around and fastened. Therefore, the rope R can be drawn out and drawn in very smoothly, and the rope-like slip can be kept good and inadvertent rope-like wear can be prevented.

  Further, the rope R is always in contact with the guard 1 and is not in direct contact with the closed chock C, so that the wear of the rope R can be reduced as much as possible, and the guard 1 is reinforced with high-performance fibers. In order to come into contact with the closed chock C via the band cloth 3, the closed chock C is pressed at a high pressure and is not easily worn by frictional contact with the closed chock C. Needless to say, it can be much longer. In addition, the second embodiment can also reduce the wear of the rope R as much as possible because the compatibility between the rope R and the base material 2 is good.

  In each of the first and second embodiments described above, the reinforcing band fabric 3 made of high-functional fibers is on the surface of the base material 2 and in the whole area from the viewpoint of increasing the strength of the base material 2. It is desirable to provide it. However, since the high-performance fiber is expensive, in each of these examples, the above-described method is used.

  In addition, in this device, it is also important to reduce the wear of the rope R as much as possible, and it is necessary to select the fibers of the guard 1 from the properties of the fibers used for the rope. In each of the above embodiments, an example in which the properties of the fibers used for the rope R are compatible with the polyester synthetic fibers is described. However, when the properties of the rope R do not match the polyester synthetic fibers, the reinforcing band 3 is applied to the front side of the base material 2 so that the reinforcing band 3 made of high-performance fibers is in direct contact with the rope R. It is desirable to adopt. On the contrary, by applying the reinforcing band fabric 3 made of this high-performance fiber to both the front and back surfaces of the base material 2, it is possible to correspond to the rope R that is familiar with the high-function fiber and to increase the strength of the base material 2 at the same time. Can be adopted. Thus, in this device, in order to apply the reinforcing band fabric 3 to the base material 2, the base material 2 is appropriately adopted depending on the various situations as described above, such as either the front or back side of the base material 2 or both of the front and back sides. Needless to say, it is desirable.

  The embodiments described above are not necessarily limited to the structures shown in the drawings, and the structures shown in the drawings can be combined with each other or used within a range that does not contradict the gist of the invention. . As an example, the example in which the flange 11 and the slit 12 are adopted as the allowance 10 in the first embodiment is shown, but only the flange 11 or only the slit 12 may be used. Further, in the second embodiment, similarly, an example in which only the slit 12 is employed has been described. However, it is also possible to replace the structure with the flange 11.

Utility Model Registration No. 3109434

  This device is mainly used for, for example, marine hawser ropes, tugboat ropes, marine ropes, and, if necessary, aquaculture fisheries ropes for aquaculture, stationary, bottom dredging, etc. The present invention relates to a guide guard used by applying to (hereinafter simply referred to as a rope in this device).

  From a marine terminology, the conductor is called a chock or a fairleader. Specifically, it is provided on the deck of a ship in order to guide, for example, when a tugboat rope or a ship hawser rope is fed or unloaded. The shape may be a ring shape (closed chock) or a C-shape (open chock) with the top open.

Conventionally, the portion of the rope that is in contact with each of the ropes of the ship is generally determined.
However, at these contact portions, the contact surface with these conductors is worn by friction. In particular, wear damage during the use of fiber cords is likely to occur at this site.

  Therefore, as shown in FIG. 14, these parts are devised so as to surround a protective material called a protector 1 ′ so as to reduce the wear of the rope and to extend the life of the rope as much as possible. . Specifically, a rectangular patch is wrapped around the rope.

  However, this type of protector 1 'that is wound around the conventional rope is generally made of a plain woven fabric of polyester fibers. In addition, it is necessary to set the attachment position of the protector 1 'to tie the rope piece (not shown) to the loop piece provided on the short piece of the rectangular protector, and to tie it to the rope with this, It was difficult to correctly contact the protector 1 'and the conductor. That is, at the start of the mooring operation, the protector 1 'is first attached to a required portion of the rope. However, in reality, the position where the cable is initially attached does not fit perfectly with the guide device due to the extension of the cable itself during the extension of the cable or during subsequent cable tension. As a result, the protector 1 'did not contact the conductor correctly, and it was necessary to adjust the attachment position of the protector 1' again. Therefore, as a result, much work and time are required for the mounting operation of the protector 1 '.

  Therefore, there is a demand for a means that does not require the trouble of attaching the protector to the cable-like shape, eliminates inadvertent friction with the conductor, and extends the cable-like service life.

In order to respond to this demand, the applicant of the present invention previously abandoned the method of attaching a protector in the form of a cable, and devised and proposed a new means (see Patent Document 1).
The concrete structure of the guard for a guiding device according to this proposal is that a reinforcing cloth member made of a high-performance fiber is integrally sewn on a base material made of a polyester-based synthetic fiber, and at least two opposite parts of the base material are opposed to each other. A guard piece is formed by integrally sewing a piece of a fixed string insertion portion forming cloth piece (loop piece) on the edge, and this is tied to a conductor with a tie string passed through the loop piece. Further, the depth width of the reinforcing cloth member is substantially the same as the depth width of the guiding device, and the lateral width is composed of one piece of a horizontally long rectangle formed substantially the same as the lateral width of the base material. In the center, the long side was sewn in parallel with the long side direction of the base material.

  However, since the rope insertion hole of the conductor has a circular shape or a curved surface of the letter C or U, the guard is stiff during the actual use of the structure proposed above. As a result, it was found that it was difficult to perform the desired functions. In addition, the bigger problem is that the reinforcing cloth member is a single rectangular piece having a width substantially the same as the depth of the conductor, and is sewn in the center of the depth of the base material. It will be located near the edge of the rope insertion hole of the conductor, and this sewing thread will come into contact with the rope and wear, and the end of the reinforcing cloth member will be rolled up and peeled off from the base material, resulting in the base material It is also possible that the cable will be worn and the cable may be worn by coming into direct contact with the conductor.

As a result of various studies on this phenomenon, it was found that the guard is a single piece of cloth for both the base material and the reinforcing cloth member, and they are overlapped and sewn together, so that the familiarity with the curved surface is not good.
As a result of various considerations based on this verification result, we came up with a structure that divides the base material in contact with the rope insertion hole of the conductor into multiple parts along the width direction, that is, the circumferential direction of the rope insertion hole. As a result of trials, it was found that there was no problem in practical use. As a result of further studies, a structure that can achieve the intended purpose successfully was finally obtained, and is proposed here.

  Therefore, the problem to be solved by the present invention is to improve the familiarity of the guard to the rope insertion hole of the guider as much as possible so that it can be securely attached over a long period of time without misalignment. It is.

  In order to solve the above technical problems, a guide guard according to claim 1 of the present invention includes a base material made of a polyester-based synthetic fiber and a high-performance fiber sewn integrally with the base material. A stringer guard composed of a reinforcing cloth member and a fixed string insertion portion forming cloth piece sewn integrally with the base material, wherein the base material is formed in a strip shape. Reinforced cloth members formed into a required shape by sewing a plurality of constituent fabric pieces with their long side edges attached to each other, and having the same size as that of the base material It is constructed by superposing on the base material and sewing together.

  The guard for a guiding device having the above-described structure is attached to the guiding device via a string, etc., with the base material side applied to the surface of the cable insertion hole of the guiding device, tied to the insertion portion forming piece of the fixed string. . Once the guard is attached, it will not be detached from the conductor unless the attachment string or the like is released. As a result, the surface of the conductor, particularly the surface of the cable insertion hole in contact with the cable shape, is always covered with this guard. Therefore, there is no direct contact between the conductor and the cable shape, and the risk of damage to the cable shape due to friction can be reduced. In addition, the base material is formed into a required shape by sewing a plurality of strips with their long side edges attached to each other, so that it is easy to bend at a small width like a bellows fold, leading to It comes in contact with the surface of the cord insertion hole of the vessel well.

  As described above, the conductor guard according to the first aspect of the present invention is not stiff like the conventional one, and at least the base material is bent with a small width like a bellows fold. It has become possible to prevent the possibility of misalignment for a long period of time by being familiar with the surface of the hole. Furthermore, since the reinforcing cloth member formed in substantially the same vertical and horizontal dimensions as the base material is superposed on the base material and integrally sewn, the frequency of the sewing thread of the reinforcing cloth member coming into contact with the rope is possible. As a result, the end of the reinforcing cloth member is less likely to be rolled up or peeled off from the base material, and the risk that the cord may directly contact the wearer and be worn away can be solved well. became.

  Moreover, since the conductor is surrounded by a guard using high-performance fibers, the wear of the rope can be reduced as much as possible. At the same time, unlike the conventional case, it is not necessary to attach or remove the protector to the cable. As a result, it is possible to extend and store the cords efficiently and easily, and greatly contribute to the improvement of work efficiency. In particular, due to the presence of high-function fibers, the useful life of the guard itself can be increased and the intended purpose can be achieved successfully.

Further, in this device, as described in claim 2, the reinforcing cloth member is a base material obtained by sewing a plurality of strip-shaped reinforcing band cloth base materials with their long side edges attached to each other. It is desirable that it is formed in the required shape matched.
This is because, as with the base material, there is no stiffness as with a single sheet, and it is possible to further adapt to the rope insertion hole of the conductor and prevent the position from shifting for a longer period of time.

From another point of view, the present invention can adopt a configuration in which the shape of the guard is rectangular or mountain-shaped as described in claims 3 to 4.
In the case of a rectangular shape, it is to be well tied to the main ridge-side cable with internal and external fixing hooks, etc., with fixed straps, etc., through the piece of cloth forming the fixed straps on both sides of the guard. Even if the tension direction of the rope is forward or backward, it can cover the entire inner circumference of the rope insertion hole of the rope, and the rope will be in direct contact with the rope and worn Fear can be resolved well.
In addition, the Yamagata has the following advantages. In other words, in general, the ropes installed at the bow have hooks to secure the rope on the deck side, but there are no facilities on the outer wall, so the guard must be fixed only on the deck side. . Therefore, if the guard has the same vertical dimension over the entire width, when it is attached to the conductor, the part located on the upper side of the guard may hang down by its own weight and block the rope insertion hole of the conductor. Will arise. However, according to this configuration, since the upper portion is a short side portion of the guard, even if the portion hangs down by its own weight, the risk of blocking the rope insertion hole of the conductor can be avoided well.

In addition, as described in claim 5, the base material constituting the base material piece and the reinforcing band member base material of the reinforcing cloth member are adjacent to each other at one side of each other. The edges of the base material constituting fabric pieces that are adjacent to each other are different from each other in the width direction of the guard so that they do not overlap with the edges that are attached together. It is desirable not to superimpose in the vertical direction on the side edges of the sides that are next to each other.
That is, the base material constituting cloth piece of the base material and the reinforcing belt cloth base material of the reinforcing cloth member are made to have different phases in the short side direction of each other, whereby the base material constituting cloth piece of the base material and the reinforcing band cloth of the reinforcing cloth member This is because it is possible to satisfactorily prevent the site of attachment of the long side with the base material from being vertically polymerized to form a weak point of strength.

In this device, the guard for the conductor is provided with a clearance for absorbing a dimensional difference between the inner side and the side edge of the conductor on the long sides opposite to each other. It is desirable that it is formed.
As for a conductor, the diameter of the inner side and the side periphery following it necessarily differs (refer FIG. 9). As a result, in order to absorb the difference in diameter between the inside and outside of the conductor, the guard is wrinkled toward the inside of the conductor. However, due to the existence of this allowance, the edge of the guard becomes substantially longer than the center side of the guard. Therefore, when attached, it is well adapted to the inner side and the side periphery, and can keep the cord-like slip well and prevent inadvertent cord-like wear.

Furthermore, as described in claims 7 to 9, it is desirable that the allowance is a ridge, a slit, or both.
By pulling the guard to the left and right, the two or one peripheral portions of the guard that are opposite to the peripheral portion of the conductor can be expanded laterally, and the length is longer than the length of the central portion (180 It is possible to match the lengths of two or one of the opposing edges of the guard well with the length of the side edge with respect to the side edge of the long conductor. As a result, even though there is a dimensional difference between the inner side, that is, the right and left inner side surfaces and the side rim of the conductor, the guard should be wound around the conductor correctly with the least possible occurrence of wrinkles. This is because it can be concluded.

Furthermore, in this device, as described in claim 10, it is desirable that the high-performance fiber is provided on either the front or back side of the guard, or on the front or back side, or mainly on the surface of the guard, at a site that abuts the streak.
From the viewpoint of increasing the strength of the guard, it is ideal to provide the entire area on the front or back surface. However, since high-performance fibers are expensive, it is desirable from the viewpoint of economic efficiency to reinforce the portions where the cords contact the guard. Also, in practice, the cable shape does not contact the entire circumference of the conductor (although depending on the position where the conductor is installed), in many cases the side from the inner peripheral surface of the conductor Since it is over the circumferential surface, it is desirable to provide it at this site, particularly at the site that contacts the inner circumferential surface.

  In addition, it is possible to select the front and back or both sides of the polyester-based synthetic fiber and assign the high-performance fiber to this, regardless of the type of abrasion that occurs due to the difference in the fibers used in the rope. This method is employed depending on whether the high-performance fiber should be brought into direct contact with the polyester-based synthetic fiber.

Furthermore, in this device, as described in claim 11, the fixed-string insertion portion forming cloth piece is formed by forming a strip-like cloth piece half-folded at both ends in the length direction and forming an eye. desirable.
Compared to a metal ring, it can be easily attached to the base material by sewing, and it can be used for many years without damaging the conductor and without any risk of corrosion. Because.

  Examples of the high-performance fiber employed include wholly aromatic polyamide fiber, wholly aromatic polyester fiber, polyparaphenylene benzobisoxazole fiber, polyvinyl alcohol fiber, and ultrahigh molecular weight polyethylene fiber. Among these, ultra high molecular weight polyethylene fibers are preferable.

  Moreover, the above highly functional fiber can be manufactured by a known method or a method equivalent thereto.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will now be described with reference to the drawings in which the conductor guard according to the present invention is applied to a conductor provided on the shore side and the bow, for example, a closed chock.

  Example 1 is the case where the guard for a conductor according to the present invention is applied to a closed chock, which is an example of a conductor, provided on the deck of a ship, and will be described based on the description of FIGS.

Various shapes are adopted for the guard 1 for a guiding device of the present invention depending on the closed chock C (see FIG. 9) to be applied. In this Example 1, as shown in FIGS. 1-4 and 6-8, it is a rectangular mat shape, and the ratio of length to width is formed about 1 to 1.3.
As shown in FIG. 1, the guard 1 basically has a rectangular base material 2 and a rectangular shape substantially the same size as the base material 2, which is integrally sewn on the surface of the base material 2. The reinforcing band member 3 is an example of the reinforcing cloth member, and the end portions are protruded outward from the long side edge 2A of the substrate 2 and the long side edge 3A of the reinforcing band 3, respectively. The long-side edges 2A and 3A are formed of fixed-string insertion portion-forming cloth pieces 4 that are integrally sewn at predetermined intervals in a direction along the edges.

The base material 2 and the insertion part forming cloth piece 4 of the fixed string are formed of a general synthetic fiber, for example, a polyester synthetic fiber, and the base material 2 is formed in a rectangular mat shape. As shown in the figure, a sling belt having a narrow strip shape is employed. Reinforcement band cloth 3 is a high-performance textiles and the skin material, obtained by a polyester-based synthetic fibers in the material.

Furthermore, each structure is demonstrated concretely.
First, as shown in FIG. 3, the base material 2 is composed of a plurality of strip-shaped base material constituting cloth pieces 2B obtained from polyester synthetic fibers (in the example shown, the first sheet 2B1 to the sixth sheet 2B6). 6 sheets) are obtained by attaching the edges 5 on the long side (the side along the vertical direction: the direction along the vertical direction on the paper surface of FIG. 3) to each other to form a rectangle. The vertical and horizontal dimensions of the base material 2 disclosed in this example are as follows. The vertical direction is 1100 mm, the horizontal direction (the direction along the short side of the base material constituting fabric pieces 2B1 to 2B6: the horizontal direction on the paper surface of FIG. (Direction along) is formed to 1200 mm. Further, the width of each of the base material constituting cloth pieces 2B1 to 2B6 is approximately 1/6 of the horizontal width of the entire base material 2, and is formed to be 200 mm.

As shown in FIG. 4, the reinforcing band fabric 3 includes a plurality of reinforcing band fabric bases 3B formed in a strip shape using polyester synthetic fibers made of the same material as the base material 2 (first sheet 3B1 in the illustrated example). -7th sheet 3B7) and as shown in the partial enlarged cross-sectional view of FIG. 5, each of the reinforcing band cloth base materials 3B1 to 3B7 is covered and folded back from the four periphery to the opposite side. consisting rope contact the cloth 6 that obtained by the material of the high-performance textiles which are sewn together at the edges. The plurality of sheets 3B1 to 3B7 of the reinforcing band fabric base material 3B obtained in this way are obtained by attaching the long side edges 7 to each other and forming a rectangle. The vertical and horizontal dimensions of the reinforcing band cloth 3 disclosed in this example are 1100 mm in the vertical direction (direction along the long side of the reinforcing band cloth base material 3B: the vertical direction on the paper surface of FIG. 4), and the horizontal direction (reinforcing). The direction along the short side of the band base material 3B: the left-right direction on the paper surface of FIG. 4 is 1400 mm. In addition, the width of each of the reinforcing band fabric base materials 3A1 to 3A7 is about 1/7 of the width of the whole base material, and is formed to be 200 mm.

  Therefore, the size of the guard 1 itself is 1100 mm in the vertical direction and 1400 mm in the horizontal direction before being attached to the closed chock C. However, once attached to the closed chock C, as will be described in detail later, the end of the long side direction of the guard 1 can be expanded in the lateral width direction, and the lateral width of the guard 1 in this expanded state. Is provided with a special structure to be approximately 1580 mm to 1830 mm.

  As shown in FIG. 4, the fixed string insertion portion forming cloth piece 4 includes strip-like cloth pieces 4 </ b> A each having half-folds at both end portions in the lengthwise direction, each having an eye 8. Is configured to have a length that protrudes from the end on the long side of the guard 1 (: upper and lower ends on the paper surface of FIG. 4: 3A) to the outside by appropriate dimensions. Further, the insertion portion forming cloth piece 4 of the fixed string is arranged along the longitudinal direction of the reinforcing band cloth base material 3B, that is, the direction along the long side of the reinforcing band cloth base materials 3B1 to 3B7, In addition, the reinforcing band cloth base material 3B is overlapped on the reinforcing band cloth base material 3B at predetermined intervals in the lateral direction of the reinforcing band cloth base material 3B, that is, along the short sides of the reinforcing band cloth base materials 3B1 to 3B7. The reinforcing band fabric base material 3B is sewn together. In the drawing, the reinforcing band fabric bases at the left and right ends, that is, the first sheet 3B1 and the seventh sheet 3B7 are along the outermost edge, the second sheet 3B2 and the sixth sheet 3B6 are the center, and further 3 The 6th sheet 3B3 and the 5th sheet 3B5 are sewn together integrally to the reinforcing band fabric base material 3B as indicated by the sewing sewing line 9 along the innermost edge.

The base material 2 and the reinforcing belt cloth 3 as described above are sewn together as follows.
That is, as shown in FIG. 1 and FIG. 4, the center part of each short side direction of the base material constituting cloth pieces BA1 to 2B6 of the base material 2 is on the long side of the reinforcing band base materials 3B1 to 3B7. It superimposes on this reinforcement band cloth 3 so that it may be located on the attachment part of the edge 5. FIG. Next, the base material 2, the fixed string insertion part forming cloth piece 4 and the reinforcing band cloth 3 are each 1/5 from the central part in the long side direction of the base material 2 and both edges 5 (upper and lower ends on the drawing in the figure). It is attached to each of the three places, one at the center, in a single horizontal form. As a result, the base material 2, the reinforcing band cloth 3, and the fixed string insertion portion forming cloth piece 4 are sewn together. In FIGS. 3 and 4, 9A indicates a planned sewing line before sewing.

  Accordingly, at this stage, both long edges 2A of the base material components 2B1 to 2B6 of the base material 2 and both long sides of the reinforcing belt cloth base materials 3B1 to 3B7 of the reinforcing belt cloth 3 are provided. In the region from the edge 3A to the sewing line 9 at a location that is 1/5 each closer to the center, the edges 5 and 7 on the long side are free ends.

Next, the important point is the peculiarity of the sewing method after the heel.
As shown in FIG. 9, since the closed chock C has a diameter d of the side peripheral edge C4 larger than a diameter D of the left and right inner side faces C3 of the inner peripheral face C2 of the rope insertion hole C1, The configuration adapted to the difference in diameter allows the guard 1 to be wrapped around the closed chock C more accurately without any wrinkles and fastened, and the rope R as an example of the rope is further extended and retracted. It can be done smoothly.

In order to satisfy this requirement, in the present invention, as shown in FIGS. 1 to 4 and 6 to 8, two opposing edges on the long side of the guard 1, that is, the base material 2 and the reinforcing cloth The two margins 2A, 3A on the long side of the piece 3 are provided on the inner side of the closed chock C, that is, in the allowance 10 of two different forms for absorbing the dimensional difference between the left and right inner side surfaces C3 and the side peripheral edge C4. Is adopted.
One of the allowances 10 is a ridge 11 and the other is a slit 12.

As shown in FIGS. 1, 2, 4, 6 and mainly FIG. 6, the ridge 11 is formed by the left and right sides 2 </ b> B <b> 1, 2 </ b> B <b> 6 of the base material constituting fabric pieces 2 </ b> B <b> 1 to 2 </ b> B <b> 6 and the pair 2 </ b> B <b> 2, 2 </ b> B5 inside thereof. It is.
That is, the left and right sides of the free end portions of each of the base material constituting cloth pieces 2B1, 2B2, 2B5, 2B6, that is, the length of the outer portion from the upper and lower sewing sewing lines 9 (or the planned sewing line 9A). Each of the left and right side edges 13 on the side is sequentially drawn toward the free end so as to draw a partial arc on the side edge 7 on the long side of the corresponding reinforcing band base material 3B. Sewing to material 3B. More specifically, the first, second, fifth, and sixth base material constituting cloth pieces 2B1, 2B2, 2B5, and 2B6 correspond to the first reinforcing band cloth base material 3B1. The second reinforcing band base material 3B2, the third reinforcing band base material 3B3, the fifth reinforcing band base material 3B5, the sixth reinforcing band base material 3B6, and the seventh sheet This reinforcing band corresponds to each of the left and right side edges 13 on the long side of the outer part from the sewing sewing line 9 to the long side edge 7 of the reinforcing band cloth base material 3B7 attached to each other. The cloth base material 3B is sewn on the reinforcing band cloth base material 3B as indicated by a sewing sewing line 9 so as to draw a partial arc in order toward the edge 7 on the long side of the cloth base material 3B. In this way, at the left and right central portions of the four base material constituting cloth pieces 2B1, 2B2, 2B5, and 2B6 of the first, second, fifth, and sixth sheets from the sewing sewing line 9 respectively. A ridge 11 that rises in a mountain shape that becomes higher at the free end side is formed.

  When the guard 1 is pulled left and right, as shown in FIGS. 7 and 8, the collar 11 is flattened from the chevron and has two peripheral edges (long sides) opposite to the peripheral edge of the Claude Chock of the guard 1. The side edges 2A, 3A) expand laterally, and the length S can be longer (about 180 to 430 mm) than the length S1 of the part sewn in a rectangle on the center side. The lengths of the two opposite peripheral edges (long side edges 2A, 3A) of the substrate 2 can be matched to the length of the side peripheral edge C4. As a result, although there is a dimensional difference between the inner side, that is, the left and right inner side surfaces C3 and the side peripheral edge C4, as shown in FIG. It can be wrapped around the closed chock C and fastened.

Next, the slit 12 which is another structure of the clearance allowance 10 is demonstrated.
As shown in FIGS. 1, 4, and 6, two base material constituting cloth pieces 2 </ b> B <b> 3 and 2 </ b> B <b> 4 that overlap with the fourth reinforcing band base material 3 </ b> B <b> 4 in half in the width direction. The left and right sides of the fourth reinforcing belt base material 3B4 corresponding to the fourth reinforcing band fabric 3B4 corresponding to the long edge portions 13A on the outer side of the sewing sewing line 9 are gradually moved toward the free end. As shown by the sewing sewing line 9, a partial arc is drawn on each of the long side edges 7. And the edge part 13B on the opposite side to the edge part 13A on the long side of the two base material constituting cloth pieces 2B3 and 2B4 on the third sheet and the fourth sheet is the reinforcing band cloth. It is a free end without sewing to the base material 3B.

  Accordingly, the fourth reinforcing belt base material 3B4 is not integrated with the third and fifth reinforcing belt base materials 3B3 and 3B5, but on the long side where they are attached to each other. Freely independent of the third and fifth reinforcing band base materials 3B3 and 3B5, which are adjacent to each other on the long side edge portion 14 on the side of the long side that is outside the sewing sewing line 9 at the side edge. 2, 4 and 6, mainly as shown in FIG. 6, a slit 12 is formed between the fourth sheet and the third and fifth sheets adjacent to each other. Thus, by providing the slit 12, the outer edge 13B in the left-right direction of each of the third piece 2B3 and the fourth piece 2B4 of the base material constituting cloth pieces and the fourth piece of the reinforcing band cloth base material. When the left and right edges 14 of 3A4 become free ends and the guard 1 is expanded as shown in FIGS. 7 and 8, the guard 1 can be expanded further than the ridge 11, and the generation of folds is reduced as much as possible. Then, it can be wrapped around the closed chock C more accurately and fastened.

  The conductor guard 1 configured as described above is wound around a portion where the rope R is in contact with the closed chock C and fastened. More specifically, as shown in FIG. 10, the inner peripheral surface of the rope insertion hole C1 of the closed chock C, the insertion hole bottom C2, the left and right inner peripheral surfaces C3 connected thereto, and the insertion hole bottom C2 And it is wound around the side periphery C4 which continues in front and behind the left-right inner peripheral surface C3, and is fastened. The fastening is performed in such a manner that the fixed string 15 is sequentially tied up to the eye 8 of the fixed string insertion part forming cloth piece 4 through the fixed string 15.

  Therefore, the rope R always contacts the guard 1 and does not contact the closed chock C directly. As a result, the wear of the rope R can be reduced as much as possible. In addition, since the guard 1 comes into contact with the closed chock C via the reinforcing band 3 made of high-performance fiber, it is pressed against the closed chock C with a high pressure, and even by frictional contact with the closed chock C, The service life of the guard 1 can be significantly increased without being worn out. Furthermore, in the case of this example, since the compatibility between the rope R and the base material 2 is good, the wear of the rope R can be reduced as much as possible.

  In addition, a plurality of sheets in which the base material 2 and the reinforcing belt cloth 3 are each formed into a strip shape are attached to the long edges 5 and 7, respectively, and the base material constituting cloth piece 2B of the base material 2 The reinforcing band cloth base material 3B of the reinforcing band cloth 3 is formed in a rectangular shape by being polymerized by making phases different from each other in the short side direction, and is bent in a small width like a bellows fold. It is easy to adjust the diameter d of the side edge C4 well, and it can be wound more accurately without wrinkles. Furthermore, since the base part constituting cloth piece 2B of the base material 2 and the reinforcing belt cloth base material 3B of the reinforcing belt cloth 3 are not integrally wrapped with each other, the phases are different from each other, so that they are integrally sewn. It is possible to successfully prevent the occurrence of a weak point of strength, and it can be used safely for a long time.

  Further, the guard 1 is provided with a clearance 10 composed of a collar 11 and a slit 12, and the collar 11 is extended, and the slit 12 is expanded so that the side edge C4 of the closed chock C having a long dimension is expanded. The lengths of the two opposite edges of the guard 1 (the edges 2A and 3A on the long side) can be matched to the length of the side edge C4. As a result, despite the dimensional difference between the inner side, that is, the left and right inner side surfaces C3 and the side peripheral edge C4, the guard 1 is appropriately wound around the closed chock C with the least possible occurrence of wrinkles. Can be concluded. Therefore, the rope R can be drawn out and drawn in very smoothly, and the rope-like slip can be kept good and inadvertent rope-like wear can be prevented.

  Further, the rope R is always in contact with the guard 1 and is not in direct contact with the closed chock C, so that the wear of the rope R can be reduced as much as possible, and the guard 1 is reinforced with high-performance fibers. In order to come into contact with the closed chock C via the band cloth 3, the closed chock C is pressed at a high pressure and is not easily worn by frictional contact with the closed chock C. Needless to say, it can be much longer.

  In the above embodiment, it goes without saying that it can be applied to an open chop and a fair leader instead of a closed chock.

  The position where the reinforcing band cloth 3 is provided cannot be determined unconditionally depending on the difference in the fibers of the rope R used, and the size and structure of the closed chock C. However, basically, it is desirable from the viewpoint of economic efficiency to reinforce mainly the part where the base material 2 substantially contacts the closed chock C or the part where the rope R contacts the base material 2. In practice, the rope R does not contact the entire circumference of the closed chock C, but it depends on the position where the closed chock C is provided. For this reason, it is desirable to provide this portion, particularly a portion that contacts the inner peripheral surface. At a minimum, it is desirable to provide a width that is about one third of the width of the substrate 2.

Example 2 is a case where the guard for a guiding device according to the present invention is applied to a closed chock provided at the deck bow portion of a ship, and will be described based on the description of FIGS.
The same members and configurations as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIGS. 11 to 12, the second embodiment is characterized in that the overall shape in plan view is a mountain shape with a long central portion and short left and right sides.

  First, as shown in FIG. 11, the base material 2 is composed of a plurality of strip-shaped base material constituting cloth pieces 2B obtained from polyester synthetic fibers (in the example shown, the first sheet 2B1 to the fifth sheet 2B5). 5 sheets) are obtained by attaching the edges 5 on the long side (the side along the vertical direction: the direction along the vertical direction on the paper surface of FIG. 11) to each other. Specifically, it is composed of three strip-shaped sheets 2B2 to 2B4 disposed in the central portion and a pair of side base material constituting cloth pieces 2B10 and 2B50 disposed on the left and right sides thereof. The side base material constituting cloth pieces 2B10 and 2B50 disclosed in this embodiment are substantially half the length of the long side of the base part constituting cloth pieces 2B20 to 2B40 in the central portion in the longitudinal direction, and the central portion in the lateral direction. It is formed to have a width approximately twice as large as that of one base material constituting cloth piece 2B20-40. Further, the vertical and horizontal dimensions of the vertical base material 2 are as follows. First, in the longitudinal direction, the long central portion is 750 mm, the short side is 450 mm, and the lateral width is 1400 mm. Further, the width of each of the other base material constituting cloth pieces 2B2 to 2B4 except for the left and right sides is 1/7 of the width of the entire guard 1 and is formed to be 200 mm. Further, the left and right side portions are approximately one third of the entire guard 1 and are formed to be 400 mm. Accordingly, the lateral width of the central portion is 600 mm, and the lateral width of the side portion is 400 mm. And it forms so that it may become a mountain shape by planar view shape by aligning the one side of the vertical direction (lower side edge 2A in the figure) in a horizontal straight line.

As shown in FIG. 12, the reinforcing band fabric 3 includes a plurality of reinforcing band fabric base materials 3 </ b> B formed in a strip shape using polyester synthetic fibers of the same material as the base material 2 (first sheet 3 </ b> B <b> 10 in the illustrated example). and eight 8 th 3B80), the rope contacting the cloth 6 that obtained by the material of the high-performance textiles which are sewn together over the reinforcing band fabric substrate 3B10~3B80 each surface Composed. The plurality of sheets 3B10 to 3B80 of the reinforced band fabric base material 3B obtained in this way are each provided with the edge 7 on the long side (the side along the vertical direction: the direction along the vertical direction on the paper surface of FIG. 12). Obtained by associating each other. Specifically, it is composed of four strips 3B30 to 3B60 arranged in the central portion, and a pair of side reinforcing belt bases 3B10 to 20 and 3B70 to 80 arranged on the left and right sides thereof. . The side reinforcing band cloth base materials 3B10 to 20 and 3B70 to 80 disclosed in this embodiment are approximately two-thirds of the length of the long side of the reinforcing band cloth base materials 3B30 to 3B60 in the center portion in the longitudinal direction. In the lateral direction, the outermost pair 3B10, 3B80 is formed to have a width approximately half the width of one reinforcing band base material 3B on the center side, and one inner side is formed to be the same size as the reinforcing band base material 3B of the central part. . Further, the vertical and horizontal dimensions of the vertical base material 2 are as follows. First, in the longitudinal direction, the central part has a long portion of 950 mm, the side portion has a length of 650 mm, and the lateral width is also 1400 mm. Moreover, the width of each of the other reinforcing band base materials 3B20 to 3B70 except for the pair on the left and right sides is 1/7 of the width of the entire guard 1, and is formed to be 200 mm. Furthermore, the pair of the left and right sides is one-fourth of the entire guard 1 and is formed to be 100 mm. And it forms so that it may become a mountain shape by planar view shape by aligning the one side of the vertical direction (lower side edge 3A in the example) in a horizontal straight line. In addition, the longitudinal dimension is configured to be 200 mm longer than the base material constituting piece 2B in both the central portion and the side portion. Specifically, the upper and lower edges 2 </ b> A of the base material 2 are arranged 100 mm from the upper and lower edges 3 </ b> A of the reinforcing band 3, respectively.
In addition, a fixed string insertion portion forming cloth piece 4 is integrally sewn to a portion of 100 mm below the reinforcing cloth piece 3 at predetermined intervals in the width direction.
The fixed string insertion portion forming cloth piece 4 is made of the same material as in the first embodiment.

  Then, as shown in FIG. 11, the base material constituting cloth piece 2B of the base material 2 and the reinforcing cloth portion cloth base material 3B of the reinforcing band fabric 3 are integrated by being polymerized with different half pitch phases in the short side directions. It is formed by sewing.

  Further, within the range in which the base material constituting cloth piece 2B is set back, that is, in the range of 100 mm, the edge 7 on the long side of the reinforcing cloth portion cloth base material 3B is a free end and the slit 12 is formed. The

  According to the configuration shown in the second embodiment, as shown in FIG. 13, the mountain-shaped top side of the closed chock C provided in the bow portion of the deck is placed in a horizontal straight line with the top side of the mountain shape outside the ship. Place the base 2 side against the surface of the rope insertion hole C1 of the closed chock C with the edge sides 2A and 3A facing the inside of the ship (the deck side), and tie them to the eye 8 of the insertion part forming piece 4 of the fixed string. The guard 1 is attached to the closed chock C through the like. The guard 1 once attached will not be detached from the closed chock C unless the attachment string or the like is released. As a result, the closed chock C, particularly the surface of the rope insertion hole C1 in contact with the cord shape, is always covered with the guard 1. Therefore, there is no direct contact between the closed chock C and the cable shape, and the risk of damage to the cable shape due to friction can be reduced. In addition, a plurality of sheets in which the base material 2 and the reinforcing band cloth 3 are each formed into a rectangular shape are sewn together with the long edges 5 and 7 attached to each other to form a rectangular shape. Therefore, it is easy to bend with a small width like a bellows fold, and it can be well adapted to the diameter d of the side periphery C4 and can be wound more accurately without wrinkles.

By the way, it should be noted that the attachment is such that the long central portion of the guard 1 is located on the lower surface side in the insertion hole C1 that becomes the contact surface of the rope of the closed chock C.
In general, the closed chock C provided at the bow has hooks to secure the rope on the deck side, but since there are no facilities on the outer wall, the guard 1 must be fixed only on the deck side with a loop. Absent. Therefore, if the guard 1 has the same vertical dimension over the entire width, when the guard 1 is attached to the closed chock C, the portion located above the guard 1 hangs down by its own weight and closes the rope insertion hole C1 of the closed chock C. There is a risk that it will end up.
However, according to the configuration of the second embodiment, since the upper side is the short side portion of the guard 1, even if the portion hangs down by its own weight, the rope insertion hole C1 of the closed chock C may be blocked. Can be avoided successfully.

  In addition, as in Example 1, the base material constituting cloth piece 2B of the base material 2 and the reinforcing cloth portion cloth base material 3B of the reinforcing band cloth 3 are polymerized with different phases in the direction of the short sides of each other and integrally sewn. Since it is worn and formed in a rectangular shape, it is easy to bend with a small width like a bellows fold, and it can be well adapted to the diameter d of the side edge C4 of the closed chock C and can be wound more accurately without wrinkles. Can do. Furthermore, since the base part constituting cloth piece 2B of the base material 2 and the reinforcing belt cloth base material 3B of the reinforcing belt cloth 3 are not integrally wrapped with each other, the phases are different from each other, so that they are integrally sewn. It is possible to successfully prevent the occurrence of a weak point of strength, and it can be used safely for a long time.

  Further, the guard 1 is provided with a clearance 10 composed of a slit 12, and the slit 12 expands so that the side edge C4 of the closed chock C having a long dimension with respect to the side edge C4 of the guard 1 is at least on the deck side. The length of the long side edges 2A and 3A can be matched well with the length of the side edge C4. As a result, despite the dimensional difference between the inner side, that is, the left and right inner side surfaces C3 and the side peripheral edge C4 of the closed chock C, the guard 1 is reduced as much as possible to reduce wrinkles as much as possible. It can be wrapped around and fastened. Therefore, the rope R can be drawn out and drawn in very smoothly, and the rope-like slip can be kept good and inadvertent rope-like wear can be prevented.

  Further, the rope R is always in contact with the guard 1 and is not in direct contact with the closed chock C, so that the wear of the rope R can be reduced as much as possible, and the guard 1 is reinforced with high-performance fibers. In order to come into contact with the closed chock C via the band cloth 3, the closed chock C is pressed at a high pressure and is not easily worn by frictional contact with the closed chock C. Needless to say, it can be much longer. In addition, the second embodiment can also reduce the wear of the rope R as much as possible because the compatibility between the rope R and the base material 2 is good.

  In each of the first and second embodiments described above, the reinforcing band fabric 3 made of high-functional fibers is on the surface of the base material 2 and in the whole area from the viewpoint of increasing the strength of the base material 2. It is desirable to provide it. However, since the high-performance fiber is expensive, in each of these examples, the above-described method is used.

  In addition, in this device, it is also important to reduce the wear of the rope R as much as possible, and it is necessary to select the fibers of the guard 1 from the properties of the fibers used for the rope. In each of the above embodiments, an example in which the properties of the fibers used for the rope R are compatible with the polyester synthetic fibers is described. However, when the properties of the rope R do not match the polyester synthetic fibers, the reinforcing band 3 is applied to the front side of the base material 2 so that the reinforcing band 3 made of high-performance fibers is in direct contact with the rope R. It is desirable to adopt. On the contrary, by applying the reinforcing band fabric 3 made of this high-performance fiber to both the front and back surfaces of the base material 2, it is possible to correspond to the rope R that is familiar with the high-function fiber and to increase the strength of the base material 2 at the same time. Can be adopted. Thus, in this device, in order to apply the reinforcing band fabric 3 to the base material 2, the base material 2 is appropriately adopted depending on the various situations as described above, such as either the front or back side of the base material 2 or both of the front and back sides. Needless to say, it is desirable.

  The embodiments described above are not necessarily limited to the structures shown in the drawings, and the structures shown in the drawings can be combined with each other or used within a range that does not contradict the gist of the invention. . As an example, the example in which the flange 11 and the slit 12 are adopted as the allowance 10 in the first embodiment is shown, but only the flange 11 or only the slit 12 may be used. Further, in the second embodiment, similarly, an example in which only the slit 12 is employed has been described. However, it is also possible to replace the structure with the flange 11.
