The present invention relates to a strip-shaped member.

As a member for locking and stopping a vinyl sheet of an agricultural greenhouse by a sheet locking dovetail groove attached near the frame of the greenhouse, for example, a concave and convex linear member for sheet locking as shown in FIG. 6 is known. ing.
In the plan view shown in FIG. 6 (A), the concave and convex linear member 101 for seat locking has one linear side in the length direction of the linear member, and both sides thereof have obtuse angles obliquely in the width direction. A bent straight hypotenuse, the other side of each of the hypotenuses is bent so that it is parallel to the above-mentioned one side, and the front side of each of the other side is obliquely upward and obtuse. A bent straight hypotenuse, and the tip side of the hypotenuse forms a concavo-convex shape that is one adjacent side that is on the same line as the above linear one side, and this concavo-convex shape is the length of the linear member. It is composed of a shape repeated in the direction. The sheet locking concave-convex linear member 101 has a linear shape without concaves and convexes, as shown in the side view of FIG. 6B.

  By the way, the concave-convex sheet-shaped member for sheet locking that presses the sheet against the bottom surface of the dovetail groove should come off from the bottom surface of the dovetail groove in the groove height direction toward the dovetail opening. The force generated by the seat is always acting. In other words, the force from the sheet acts on the concave-convex linear member for locking the seat in the groove height direction in the plane perpendicular to the concave-convex shape direction. The concave-convex linear member for locking the sheet has a concave-convex shape in the bottom surface of the dovetail groove, but has a linear shape with no concave-convex shape in the groove height direction perpendicular to this. For this reason, the concave-convex linear member for locking the seat does not have so high bending rigidity in the groove height direction perpendicular to the dovetail groove bottom surface that the force generated in the groove height direction against the dovetail groove bottom surface is sufficient. It is not possible to deal with it, and it is easily deformed, and the seat cannot be pressed firmly against the bottom of the dovetail groove, which may cause the seat to slip out of the seat locking dovetail groove and come off.

  The present invention has been made in view of the above-mentioned problems, and was devised to solve the problems, and the purpose thereof is to lock and stop the seat in the seat locking dovetail groove, in particular, A sheet-like line that locks the sheet in the dovetail groove against the force in the groove height direction from the dovetail bottom surface that is generated by the sheet that tries to come off from the dovetail bottom surface direction toward the dovetail groove opening side. The bending rigidity of the member in the vertical groove height direction with respect to the dovetail bottom surface is increased, and the linear member is securely deformed in the vertical groove height direction to the dovetail bottom surface to securely press the sheet, It is an object of the present invention to provide a corrugated corrugated linear member for seat locking, which can easily prevent it from coming off from the seat locking dovetail groove and coming off.

In order to achieve the above object, the present invention is a sheet locking linear member that locks and stops a sheet in a sheet locking dovetail groove, which is attached to the sheet locking dovetail groove to stop the sheet. In the above, the central portion of the linear member extending in the length direction along one groove edge of the seat locking dovetail groove is curved inward toward the groove widthwise inner side of the sheet engaging dovetail groove, and its central portion is One side that is convexly curved from the bottom of the dovetail groove toward the opening of the dovetail, and one side edge and one oblique side corner of one end of the one side edge are bent at an obtuse angle toward the inside of the groove width direction. The one oblique side in which the central part of the linear member bent obliquely at an obtuse angle from the one side one oblique side corner part toward the groove width direction inner side is convexly curved from the dovetail groove bottom direction toward the dovetail groove opening direction, The corner of the other side of the one oblique side of the one oblique side is bent at an obtuse angle in the length direction of the other groove edge of the seat locking dovetail groove. , The central portion of the linear member extending in the length direction from the corner of the one side and the other side edge along the other groove edge of the seat locking dovetail groove is convex toward the inside of the sheet locking dovetail groove in the groove width direction. The other side which is curved in a convex shape and whose central portion is convexly curved from the dovetail groove bottom direction toward the dovetail groove opening direction, and the one side of the other side of the other side and the other oblique side corner are in the groove width direction. The center of the linear member, which bends inwardly at an obtuse angle and bends inwardly at an obtuse angle from the other side of the other hypotenuse corner, is convex toward the dovetail groove opening direction from the dovetail groove bottom direction. other oblique side curved to Jo are arranged out, next the other oblique one side corner of the end portion of the other oblique side is bent at an obtuse angle to the longitudinal direction of the one groove edge of the sheet engaging dovetail one The linear member is connected to the side edge, and the linear member is repeatedly bent in the length direction of the seat locking dovetail groove in the order of one side edge, one oblique side, the other side edge, and the other oblique side. It is characterized in that it is formed by.

According to the corrugated corrugated linear member for sheet locking according to the present invention, one side and the other side of the corrugated corrugated linear member for seat locking have a sheet locking dovetail groove at the center of each linear member. Curved inwardly in the groove width direction and convexly curved from the dovetail groove bottom direction toward the dovetail groove opening direction. Since the central part of the linear member is curved in a convex shape from the dovetail bottom surface direction toward the dovetail groove opening direction, the dovetail groove bottom direction from the dovetail groove bottom direction, that is, the dovetail groove bottom direction from the dovetail groove direction. On the other hand, it is possible to increase the height by the convex curve, and to increase the bending rigidity in the groove height direction.
As a result, when the sheet is locked and locked in the sheet locking dovetail groove by using the corrugated corrugated linear member for sheet locking, be sure to pull out from the bottom surface direction of the dovetail groove toward the dovetail groove opening direction. The force from the bottom of the dovetail groove toward the opening of the dovetail groove causes the sheet to be locked in the dovetail groove. The bending rigidity from the bottom direction, that is, the dovetail groove bottom direction to the groove height direction is enhanced, and the sheet locking concave-convex corrugated linear member does not easily deform in the groove height direction perpendicular to the dovetail bottom surface, and the seat is securely It is possible to prevent the sheet from easily slipping out of the sheet engaging dovetail groove by being pushed inside the sheet engaging dovetail groove.
In addition to this, the corners of both ends of the one side and the other side of the corrugated corrugated linear member for seat locking are directly connected to both groove edges on the bottom of the dovetail groove with the lower surface side sandwiching the seat. Hit the sheet against both edges of the bottom of the dovetail groove to stop it, and also, in the middle of the one side and the other side, the outer side surface that is convexly curved in the height direction of the oblique groove Presses the sheet indirectly on both sides of the dovetail with the sheet sandwiched between them, and presses the sheet against the side of the dovetail on both sides to stop the sheet more securely. As a result, it is possible to easily prevent the seat from slipping out of the seat locking dovetail groove and coming off.

  Hereinafter, the present invention will be described more specifically based on the modes for carrying out the invention described in the drawings.

  In the figure, the sheet locking concave-convex corrugated linear member 1 is used for locking a sheet a such as a vinyl sheet of an agricultural greenhouse by locking it in the sheet locking dovetail groove 2. The seat locking dovetail groove 2 is attached, for example, near the frame of an agricultural greenhouse. The sheet a is locked by the sheet locking dovetail groove 2 and stopped, so that the agricultural greenhouse is entirely covered with the sheet a.

  In the sheet locking dovetail groove 2 in which the sheet a is locked, the opening width of the dovetail groove opening portion 22 serving as the entrance and exit is narrower than the bottom groove width of the dovetail bottom surface 21. That is, in the seat locking dovetail groove 2, the dovetail groove side surfaces 23 and the dovetail groove side surfaces 24 on both side surfaces of the dovetail groove are mutually recessed from the dovetail groove bottom surface 21 toward the dovetail groove opening portion 22, that is, in the groove height direction. The groove width is gradually decreased toward the inner side, and the sheet a is hard to come off from the inner side.

  When locking and stopping the sheet a in the sheet locking dovetail groove 2, the uneven corrugated linear member 1 for sheet locking comes out from the dovetail groove bottom surface 21 toward the dovetail groove opening 22 of the entrance and exit. The force from the bottom surface 21 of the dovetail groove 21 toward the direction of the dovetail groove opening 22 is caused by the sheet a, and the bottom surface 21 of the dovetail groove 21 of the linear member 1a that locks the sheet a in the seat locking dovetail groove 2 From the direction toward the dovetail groove opening 22 direction, that is, the structure that enhances the bending rigidity in the groove height direction perpendicular to the dovetail groove bottom surface 21. With this structure, the corrugated corrugated linear member 1 for seat locking can be easily deformed from the dovetail bottom surface 21 direction toward the dovetail groove opening 22 direction, that is, in the groove height direction perpendicular to the dovetail groove bottom surface 21. Without pressing, the sheet is surely pressed inside the seat locking dovetail groove 2 to prevent the sheet from easily coming off and coming off the dovetail groove opening 22 of the sheet locking dovetail groove 2.

  The sheet locking concave-convex corrugated linear member 1 includes, for example, a long linear member 1a having a circular cross section, which is formed on one side 11, the one oblique side 12, the other side 13, the other oblique side 14, and the adjacent one side 11 again. , One oblique side 12, the other side 13, the other oblique side 14, and so on are formed in this order, and this is repeated many times in the length direction. The material of the linear member 1a used for the corrugated corrugated linear member 1 for seat locking is made of metal, resin, or the like. The linear member 1a has a diameter of 2 mm to 5 mm, for example. In particular, when the linear member 1a is made of a metal material, a material whose side peripheral surface is covered with a waterproof resin so as not to be rusted by rainwater or the like is used.

  As the material of the linear member 1a made of resin, for example, synthetic resin monofilament may be used. Synthetic resin monofilaments have excellent strength, durability, and water resistance. In particular, it has been proved that it has excellent water resistance by being used as a net for cages. For this synthetic resin monofilament, for example, polyester having excellent durability and strength is used. The synthetic resin monofilament linear member 1a has a diameter of, for example, 2 mm to 5 mm.

  The one side 11 that constitutes a part of the sheet locking concave-convex corrugated linear member 1 that is bent is formed along one groove edge 23a of the dovetail bottom surface 21 of the sheet locking dovetail 2. The central portion 11a of the linear member 1a extending in the direction is convexly curved toward the inner side of the dovetail groove bottom surface 21 of the sheet engaging dovetail groove 2 in the groove width direction, and the central portion 11a extends from the dovetail groove bottom surface 21 direction. It is formed in a configuration that is convexly curved toward the opening portion 22, that is, from the dovetail groove bottom surface 21 direction toward the groove height direction. That is, the central portion 11 a of the one side 11 is inclined inward in the diagonal groove height direction when viewed from the cross-sectional direction of the seat locking dovetail groove 2.

  The inclination angle α1 of the central portion 11a of the one side 11 is defined by the dovetail side surface 23 formed inward from one groove edge 23a of the dovetail bottom 21 and inclined from the dovetail bottom 21 in the groove height direction. It is formed so as to be slightly larger than the inclination angle β1. The inclination angles of the central portion 11a and the dovetail side surface 23 with respect to the dovetail bottom surface 21 at the groove edge 23a are both smaller than 90 degrees, and are 90 degrees> α1> β1.

  The linear member 1a on which the one side 11 is formed has elasticity. For this reason, when the corrugated corrugated linear member 1 for seat locking is attached inside the seat locking dovetail groove 2, the dovetail groove opening portion is formed from the side of the one side 11 facing the dovetail groove side face 23 from the dovetail bottom surface 21 direction. The outward side surface 11b having the central portion 11a curved in a convex shape toward the 22 direction, that is, toward the groove height direction is pressed toward the dovetail groove side surface 23. A part of the sheet a is sandwiched between the outer side surface 11b of the one side 11 curved in a convex shape toward the height of the oblique groove and the dovetail groove side surface 23, and the sheet a is pressed toward the dovetail groove side surface 23. Between the outer side surface 11b of the side edge 11 and the dovetail groove side surface 23, a part of the sheet a is reliably pinched along a curved line that is convexly curved in the diagonal groove height direction. a is hard to come off.

  The linear member 1a having the central portion 11a that is curved in a convex shape in the groove height direction of the one side 11 has a dovetail inside the seat locking dovetail groove 2 as compared with a conventional linear member that is not curved. From the groove bottom 21 direction toward the dovetail groove opening 22 direction, that is, from the dovetail groove bottom 21 direction toward the groove height direction, the height is increased by that amount. Flexural rigidity in the groove height direction increases. That is, since the bending rigidity in the groove height direction is proportional to the cube of the height, if the height of the central portion 11a is twice as large as that in the conventional case, the bending rigidity becomes several times larger, and is generated from the sheet a. With respect to the force in the groove height direction, the linear member 1a on the one side 11 is more difficult to deform than the conventional linear member by several times, and the sheet a is less likely to be disengaged from the seat locking dovetail groove 2. .

  The one slanted side 12 that constitutes a part of the bent corrugated linear member 1 for seat locking formed by bending is formed from a one side side one slanted side corner portion 15 that is one end of the one side side 11. The central portion 12a of the linear member 1a is viewed from a plane that is bent obliquely toward the inner side of the dovetail bottom surface 21 of the groove 2 at an obtuse angle, that is, from the dovetail groove opening 22 direction toward the dovetail bottom surface 21 direction. Is formed so as to be convexly curved from the dovetail bottom surface 21 direction toward the dovetail groove opening 22 direction.

  That is, the one side / one oblique side corner portion 15 is bent at an oblique obtuse angle toward the inside of the dovetail groove bottom surface 21 of the sheet engaging dovetail groove 2 in the groove width direction, but the one oblique side 12 is formed at this bent position. ing. The one side edge / one oblique side corner portion 15 is a boundary portion between the one side edge 11 and the one oblique side 12, and the obtuse interior angle is, for example, about 120 degrees.

  When the corrugated corrugated linear member 1 for seat locking is mounted in the seat locking dovetail groove 2, when viewed from the plane, that is, the dovetail groove bottom surface 21 direction from the dovetail groove opening 22 direction, the one oblique side 12 is the dovetail groove bottom surface. 21 is positioned so that the linear member 1a crosses diagonally linearly. On the other hand, when viewed from the cross-sectional direction of the seat locking dovetail groove 2 in the direction perpendicular to the plane, the central portion 12a of the linear member 1a projects from the dovetail groove bottom surface 21 toward the dovetail groove opening 22. It is formed in a curved shape.

  The linear member 1a having the central portion 12a that is convexly curved from the dovetail bottom surface 21 direction of the one oblique side 12 toward the dovetail groove opening 22 direction is a conventional linear member that is not curved in the groove height direction. In comparison with the above, inside the seat locking dovetail groove 2, from the bottom surface 21 of the dovetail groove to the direction of the dovetail groove opening 22, that is, from the bottom surface 21 of the dovetail groove, the height becomes higher by that amount. The bending rigidity of the seat locking dovetail groove 2 in the groove height direction in the cross-sectional direction increases. That is, since the bending rigidity in the groove height direction is proportional to the cube of the height, if the height of the central portion 12a is twice as large as that of the conventional case, the bending rigidity becomes several times larger and is generated from the sheet a. With respect to the upward force, the linear member 1a of the one oblique side 12 becomes more difficult to deform than the conventional linear member by several times, and the sheet a is less likely to be disengaged from the seat locking dovetail groove 2.

  The other side 13 that constitutes a part of the sheet locking concave-convex corrugated linear member 1 that is bent and formed has a length along the other groove edge 24 a of the dovetail bottom surface 21 of the sheet locking dovetail 2. The central portion 13a of the linear member 1a extending in the direction is convexly curved toward the inside of the dovetail groove bottom surface 21 of the sheet engaging dovetail groove 2 in the groove width direction, and the central portion 13a extends from the dovetail groove bottom surface 21 direction. It is formed in a configuration that is convexly curved toward the opening portion 22, that is, from the dovetail groove bottom surface 21 direction toward the groove height direction. That is, the central portion 13a of the other side 13 is inclined inward in the diagonal groove height direction when viewed from the cross-sectional direction of the seat locking dovetail groove 2.

  The one oblique side other side corner portion 16 is bent at an obtuse angle in the length direction of the other groove edge 24a of the dovetail groove bottom surface 21 of the sheet locking dovetail groove 2, but the other side edge 13 is formed at this bent position. Has been done. The one oblique side other side corner portion 16 is a boundary portion between the one oblique side 12 and the other side edge 13, and the angle of the obtuse internal angle is, for example, about 120 degrees. At this time, the one side 11 and the other side 13 which are bent at obtuse angles to the corners 15 and 16 on both ends of the one oblique side 12 are bent in opposite directions.

  The inclination angle α2 of the central portion 13a of the other side 13 is of a dovetail side surface 24 formed inward from the other groove edge 24a of the dovetail bottom 21 and inclined from the dovetail bottom 21 in the groove height direction. It is formed so as to be slightly larger than the inclination angle β2. The inclination angles of the central portion 13a and the dovetail side surface 24 with respect to the dovetail bottom surface 21 at the groove edge 24a are both smaller than 90 degrees and are 90 degrees> α2> β2.

  The inclination angle α2 of the central portion 13a of the other side 13 is substantially symmetrical to the inclination angle α1 of the central portion 11a of the one side 11, and α2≈α1. Similarly, the inclination angle β2 of the dovetail groove side face 24 formed inward from the other groove edge 24a of the dovetail groove bottom face 21 and inclined from the dovetail groove bottom face 21 in the groove height direction is the above-mentioned dovetail groove bottom face 21. The inclination angle β1 of the dovetail side surface 23 formed inward from one groove edge 23a and inclined from the dovetail bottom surface 21 in the groove height direction is substantially symmetrical to β2≈β1.

  The linear member 1a on which the other side 13 is formed has elasticity. For this reason, when the corrugated corrugated linear member 1 for seat locking is attached inside the seat locking dovetail groove 2, the dovetail groove opening portion is formed from the side of the other side 13 facing the dovetail groove side face 24 from the dovetail bottom surface 21 direction. The outer side surface 13b having the central portion 13a curved in a convex shape toward the 22 direction, that is, toward the groove height direction, is pressed toward the dovetail groove side surface 24. A part of the sheet a is sandwiched between the outer side surface 13b of the other side 13 curved in a convex shape in the height direction of the oblique groove and the dovetail groove side surface 24, but is pressed toward the dovetail groove side surface 24. Between the outer side surface 13b of the side edge 13 and the dovetail groove side surface 24, a part of the sheet a is firmly pinched along a curved line which is convexly curved in the diagonal groove height direction. a is hard to come off.

  The linear member 1a having the central portion 13a that is convexly curved in the groove height direction of the other side 13 is more dovetailed inside the seat locking dovetail groove 2 than a conventional straight linear member that is not curved. From the groove bottom 21 direction toward the dovetail groove opening 22 direction, that is, from the dovetail groove bottom 21 direction toward the groove height direction, the height is increased by that amount. Flexural rigidity in the groove height direction increases. That is, since the bending rigidity in the groove height direction is proportional to the cube of the height, if the height of the central portion 13a is twice as high as that in the conventional case, the bending rigidity is increased several times and the sheet a is generated. With respect to the force in the groove height direction, the linear member 1a on the other side 13 is less likely to be deformed than the conventional linear member by several times, and the sheet a is less likely to be disengaged from the seat locking dovetail groove 2. .

  The other oblique side 14 forming a part of the bent corrugated linear member 1 for seat locking formed by bending is a sheet locking dove from a corner 17 of another oblique side 17 which is one end of the other lateral side 13. The central portion 14a of the linear member 1a is linear when viewed from the plane of the dovetail bottom surface 21 of the groove 2 which is bent at an obtuse angle toward the inside in the groove width direction, that is, the dovetail bottom 21 direction from the dovetail opening 22 direction. Is formed so as to be convexly curved from the dovetail bottom surface 21 direction toward the dovetail groove opening 22 direction.

  That is, the other side edge and the other oblique side corner portion 17 are bent at an oblique obtuse angle toward the inside of the dovetail groove bottom surface 21 of the seat locking dovetail groove 2 in the groove width direction, but the other oblique side 14 is formed at this bent position. ing. The other side oblique line 17 is the boundary between the other side 13 and the other oblique line 14, and the obtuse interior angle is about 120 degrees, for example.

  When the corrugated corrugated linear member 1 for seat locking is mounted in the seat locking dovetail groove 2, when viewed from a plane, that is, when the dovetail groove bottom surface 21 is viewed from the dovetail groove opening 22 direction, the other oblique side 14 is the dovetail groove bottom surface. 21 is positioned so that the linear member 1a crosses diagonally linearly. On the other hand, when viewed from the cross-sectional direction of the seat locking dovetail groove 2 perpendicular to the plane, the central portion 14a of the linear member 1a is projected from the dovetail groove bottom surface 21 direction toward the dovetail groove opening 22 direction. It is formed in a curved shape.

  The linear member 1a having the central portion 14a which is convexly curved from the dovetail groove bottom surface 21 direction of the other hypotenuse 14 toward the dovetail groove opening 22 direction is a conventional linear member which is not curved in the groove height direction. In comparison with the above, inside the seat locking dovetail groove 2, from the bottom surface 21 of the dovetail groove to the direction of the dovetail groove opening 22, that is, from the bottom surface 21 of the dovetail groove, the height becomes higher by that amount. The bending rigidity of the seat locking dovetail groove 2 in the groove height direction in the cross-sectional direction increases. That is, since the bending rigidity in the groove height direction is proportional to the cube of the height, if the height of the central portion 14a is twice as high as that in the conventional case, the bending rigidity becomes several times higher, and is generated from the sheet a. With respect to the upward force, the linear member 1a of the one oblique side 14 is less likely to be deformed than the conventional linear member by a factor of several times, and the seat a is less likely to be disengaged from the seat locking dovetail groove 2.

  The other oblique side one side corner portion 18 which is one end of the other oblique side 14 is bent at an obtuse angle in the length direction of one groove edge 23a of the dovetail groove bottom surface 21 of the sheet locking dovetail groove 2. Another new adjacent side edge 11 is formed at the position. The other oblique side one side corner portion 18 becomes a boundary portion between the other oblique side 14 and the new adjacent one side side 11, and the obtuse interior angle is about 120 degrees, for example. At this time, the other side 13 that is bent at an obtuse angle to both ends of the other hypotenuse 14 and another new adjacent one side 11 are bent in opposite directions. The configuration of another new adjacent one side 11 is the same as the configuration of the one side 11.

Hereinafter, the corrugated corrugated linear member 1 for seat locking is extended in the length direction in the order of the one side 11, the one oblique side 12, the other side 13, and the other oblique side 14.

Next, the operation based on the configuration of the mode for carrying out the invention will be described below.
For example, in the work of locking a sheet a, such as a vinyl sheet of an agricultural greenhouse, into the sheet locking dovetail groove 2 attached near the framework of the agricultural greenhouse, first, a part of the sheet a is seat locked. While being inserted into the dovetail groove 2 in the longitudinal direction thereof, the corrugated corrugated linear member for sheet locking 1 is pushed into the seat locking dovetail groove 2 from the upper side of the inserted sheet a to move the sheet a upward. To the bottom 21 of the dovetail groove.

  The groove width interval of the dovetail groove opening 22 of the sheet engaging dovetail groove 2 is narrower than the groove width of the dovetail groove bottom surface 21, and the sheet engaging concave-convex corrugated linear member 1 pushed into the sheet engaging dovetail groove 2 is provided. Is narrower than the width interval between the one side 11 and the other side 13 on both width sides. Therefore, the corrugated corrugated linear member 1 for seat locking is inserted into the seat locking dovetail groove 2 from the dovetail groove opening 22 with one side edge 11 or the other side edge 13 tilted downward. It

  For example, when one side edge 11 of the corrugated corrugated linear member 1 for seat locking is inserted with a downward inclination, the one side edge 11 is directed from the upper side of the sheet a to one groove edge side 23a of the dovetail groove bottom surface 21. Then, the other side 13 is similarly pressed from the upper side of the sheet a toward the other opposite groove edge 23a in the width direction of the dovetail groove bottom 21.

  As a result, the lower surface side of one side edge / one oblique side edge portion 15 and the other oblique side / one side edge angle portion 18 of both ends of the one side edge 11 of the sheet locking concave-convex wavy linear member 1 sandwiches the sheet a. Then, the sheet a is indirectly contacted with one groove edge 23a of the dovetail bottom surface 21, and the sheet a is pressed against the one groove edge 23a of the dovetail bottom surface 21 to be stopped. Similarly, the lower side of the one oblique side other side corner 16 and the other side other oblique side corner 17 of both ends of the other side 13 of the corrugated corrugated linear member 1 for seat locking sandwiches the sheet a between them. Then, the sheet a is indirectly contacted with the other groove edge 24a of the dovetail bottom surface 21, and the sheet a is pressed against the other groove edge 24a of the dovetail groove bottom 21 to be stopped.

  At this time, in the process of pushing the corrugated corrugated linear member 1 for seat locking into the inside of the seat locking dovetail groove 2, the outer side surface 11b of the one side 11 first sandwiches the sheet a and the dovetail groove side surface 23 is sandwiched. However, since the linear member 1a of the corrugated corrugated linear member 1 for seat locking has elasticity, the one side 11 is temporarily the center of the corrugated corrugated linear member 1 for seat locking. It can be pushed into the seat locking dovetail groove 2 by deforming toward the inner side. Similarly, the outer side surface 13b of the other side edge 13 indirectly contacts the dovetail groove side surface 24 with the sheet a sandwiched therebetween, but since the linear member 1a has elasticity, the other side edge 13 is temporary. Further, by deforming toward the inner side which is the center side of the corrugated wavy linear member 1 for seat locking, it can be pushed into the inside of the seat locking dovetail groove 2.

  The one side 11 and the other side 13 on both width sides of the sheet locking concave-convex corrugated linear member 1 are temporarily deformed toward the inside thereof, and the sheet a is sandwiched between the sheet locking dovetail groove 2. When attached to the groove bottom surface 21 side, they are elastically restored, and the outer side surface 11b of the one side 11 presses a part of the sheet a toward the dovetail groove side surface 23 to stop the same, and similarly, the other side. The side surface 13b on the outer side of the side 13 presses a part of the sheet a toward the side surface 24 of the dovetail groove to stop it.

  In this way, the corrugated corrugated linear member for sheet locking 1 that locks the sheet a by pressing the sheet a into the sheet locking dovetail groove 2 to lock the sheet a is the central portion 11 a of the one side 11 on both width sides. And the central portion 13a of the other side edge 13, and the central portion 12a of the one oblique side 12 and the central portion 14a of the other oblique side 14 that connect the two are formed in a convex shape in the groove height direction perpendicular to the dovetail bottom surface 21, respectively. Has become. For this reason, the sheet engaging concave-convex corrugated linear member 1 as a whole has a higher bending rigidity in the vertical groove height direction of the dovetail groove bottom surface 21 and is moved in the groove height direction of the dovetail groove bottom surface 21 caused by the sheet a. It is possible to prevent the sheet a from slipping out of the sheet engaging dovetail groove 2 by not sufficiently deforming in the groove height direction of the dovetail groove bottom surface 21 and sufficiently pressing against it.

  It should be noted that the present invention is not limited to the embodiments for carrying out the above invention, and it goes without saying that various modifications can be made without departing from the spirit of the present invention.
