The fitting recess 14 and the through hole 12 both have a circular shape and are arranged concentrically with respect to the axis of the main body 10.

 The fitting recess 14 is a first receiving area or inner housing adapted to receive differently shaped fitting projections 4 2, 4 3, 4 3 ′ provided on different types of male parts 40. It includes a region 15 and a second storage region or outer storage region 16. More specifically, the fitting recess 14 is disposed so as to surround the inner receiving area 15 located in the center of the fitting recess 14 in the radial direction and the circumference of the inner receiving area 15. And a ring-shaped outer housing area 16. The fitting recess 14 has a first cylindrical wall portion 19 having an inner diameter “r” and a second cylindrical wall portion 20 having an inner diameter “R” larger than the inner diameter “r”. The inner housing area 15 is a space defined by the inner circumferential surface of the first cylindrical wall portion 19, and the outer housing area 16 is composed of the outer circumferential surface of the first cylindrical wall portion 19 and the second cylindrical wall. This is a space defined between the inner surface of part 20. From this, the first cylindrical wall portion 19 constitutes a boundary portion arranged between the side housing region 15 and the outer housing region 16, and the first cylindrical wall portion 19 is inside. This constitutes both an outer wall for the receiving area 15 and an inner wall for the outer receiving area 16.

 In addition, the female fitting portion 13 is provided to prevent the male portions 40, 4 6 and 4 7 from being disengaged from the inner and outer receiving areas 15 and 16 of the fitting concave portion 14. In addition, a pair of annular ribs 17 and 18 are formed on the first and second cylindrical wall portions 19 and 20. These annular ribs 17, 18 are respectively provided in the second and second so as to protrude from the upper edge portions of the first and second cylindrical wall portions 19, 20 toward the center of the fitting recess 14. The cylindrical wall portions 19 and 20 are provided at the upper edge portions. In other words, the annular rib 17 projecting from the upper edge of the first circular cylindrical wall portion 19 extends inward of the inner housing region 15 and extends from the upper edge of the second cylindrical wall portion 20. The protruding annular rib 18 extends to the outer receiving area 16 1.

In the embodiment shown in FIG. 2, a metal cover 21 is provided around the female body 10. The cover 21 is attached to the bottom part 2 2 facing the back side of the main part 10, the side part 2 3 facing the side part of the main body part 10, and the front side of the main body part 10. The section 2 facing the force and force. Cover 2 1 top 2 4 is right! A hole portion 25 is formed through the top at a position where the portion 24 faces a fitting recess 14 formed on the front surface of the main body portion 10. The male part can be inserted into the fitting concave part 14 of the female part through the hole part 25. The bottom portion 2 2 of the cover 21 faces a through hole 12 formed on the back side of the main body portion 10, and closes the through hole 12. In the embodiment shown in FIG. 3, the metal cover 2 6 attached to the book ^ 13 1 0 has the same side 2 3 as the metal cover 2 1 shown in FIG. The top part 24 and the hole part 25 have a bottom part 27 facing the back side of the main body part 10. However, this metallic cover 26 differs from the metallic cover 21 in the following points. That is, the bottom portion 27 of the cover 26 has a hole portion 28 formed so as to coincide with the through hole 12 of the main body portion 10. Accordingly, the pillar portions of the caps 3 4 and 3 6 or the two claws of the cap 3 8 can be inserted into the through hole 12 through the hole portion 28 of the cover 26.

 In the embodiment shown in FIG. 4, the metal cover 29 attached to the main body 10 is similar to the metal covers 21 and 26 shown in FIGS. Both 2 4 and hole 2 5 have side 30. However, this metal cover 29 differs from the metal covers 2 1 and 2 6 in the following points. That is, firstly, the metal cover 29 has no bottom part facing the back side of the main body part 10, and secondly, the side part 30 of the metal cover 29 has a fitting part 13 This is that it faces only the side of the base, and does not face the side of the base 11.

 FIGS. 5 and 10 show that the plastic body 10 can be attached to the fabric piece 32 in at least three different ways. That is, for this purpose, it is possible to use either the caps 34, 36 having one S¾ or the two-claw cap 38. According to FIG. 5 and FIG. 8, it is recommended to use a two-claw cap 3 8 especially for ¾ ^ in which the cover 21 having the closed bottom portion 2 2 is attached to the main body portion 10. 2 By using the claw cap 3 8, the two claws of the cap 3 8 pierce the closed bottom 2 2 of the metal cover 2 1 and plastically deform, so that the main body 1 0 and the cap 3 The highest separation strength, that is, tensile strength, for linking the 8 can be obtained. Even when using caps 3 4 and 3 6 with one pillar in combination with a body 10 covered with a cover 2 6 with an open bottom 2 8, a considerably high separation resistance or tensile strength is obtained. You can get it. In this way, the main body 10 and the caps 3 4, 3 6, 3 8 can be connected to each other, so that the fabric piece 3 is interposed between the main body 10 and the caps 3 4, 3 6, 3 8. 2 can be done.

 In the embodiments shown in FIGS. 6, 7, 9, and 10, a water-resistant structure can be provided. Furthermore, in all three embodiments, the covers 2 1, 2 6, 2 9 and the caps 3 8, 3 4, 3 6 can be provided with stamps, which serve as decoration means It is. In addition, the covers and caps can be galvanized and / or varnished.

In FIGS. 5 to 10 three separate male parts 4 0, 4 6 and 4 7 are shown, various caps can be used to attach them to the fabric piece 52 That is, Caps 49, 50 and 2 claw caps 51 having a single pillar can be connected to male parts 40, 46, 47, and this allows the male part and the cap to be connected to each other. The dough pieces 52 can be sandwiched between them.

 Each of the male parts 40, 4 6 and 4 7 includes a circular base part 41 and fitting convex parts 4 2 and 4 3 formed so as to protrude from the front center of the base part. The fitting projections 4 2 and 4 3 are different in shape.

 The fitting convex part 42 of the male part 40 has a substantially cylindrical shape and is formed by an S-spring system. The end of the fitting part 42 is enormous in the radial direction, that is, in the direction orthogonal to the direction in which the fitting convex part 42 protrudes, and a large-diameter enormous head 44 is provided. The fitting convex part 42 has a neck part 45 in the vicinity of the base end thereof. The neck 4 5 is smaller in diameter than the enormous head 4 4.

 On the other hand, the fitting convex parts 4 3 and 4 3 ′ of the male parts 4 6 and 4 7 are formed according to the ring spring system. Each of the fitting convex portions 4 3 and 4 3 ′ is ring-shaped around the shaft portion of the engaging convex portions 4 3 and 4 3 ′ extending in the protruding direction of the engaging convex portions 4 3 and 4 3 ′. I am doing. The ring-shaped fitting convex part 4 3 of the male part 46 is enormous in its end edge, and is provided with a massive part 48. On the other hand, the ring-like fitting convex part 4 3 'of the male part 47 is It has a huge number of parts!

 In particular, as can be seen from the combination of Fig. 1 1 and Fig. 1 2, the main body 10 can cooperate with two different male parts, namely both males 40 and 46. I can do it. This is because the fitting recess 14 provided on the main body 10 includes an inner receiving area 15 for cooperating with the male part 40 and an outer receiving area 16 for cooperating with the male part 46. Because.

 First, the cooperation between the main body 10 and the male part 40 will be described below. Engagement convex part 4 2 of the main part 10 0 4 fitting part 4 of the main part 10 4 When trying to insert into the inner accommodation area 15 of the 4 4 Enlargement head part of the engagement convex part 4 2 4 4 Force fitting The first cylindrical wall portion 19 is in contact with the rib 17 provided on the first cylindrical wall portion 19 of the concave portion 14 and elastically deformed in the direction in which the first circular cylindrical wall portion 19 is expanded. When the enormous head 4 4 gets over the rib 17 and enters the deep part of the heel-side accommodation area 15, the first cylindrical wall part 19 is elastically returned to its original position, and the rib 17 is a fitting convex part. 4 2 touches 4 2 neck 4 5 As a result, the enormous head portion 44 is engaged with the rib 17, and the fitting convex portion 42 is prevented from coming out of the inner housing region 15 of the fitting four portion 14. Next, cooperation between the main body 10 and the male part 46 will be described below. When the male part 4 6 ^^ convex part 4 3 is inserted into the main body part 10 0 fitting concave part 1 4 outer housing area 1 6, the fitting convex part 4 3 enormous part 4 8 force fitting concave part 14 is in contact with the rib 18 provided on the second cylindrical wall portion 20 and elastically deforms the second cylindrical wall portion 20 in the direction of expanding the diameter or the fitting convex portion 43. When the enormous part 48 passes over the rib 18 and enters the deep part of the outer housing area 16, the second cylindrical wall part 20 or the fitting convex part 43 is elastically restored to its original shape. As a result, the enormous portion 48 is engaged with the rib 18, and the fitting convex portion 43 is prevented from slipping out of the outer accommodating area 16 of the force fitting DB portion 14. Similarly, FIGS. 13 and 14 and FIGS. 15 and 16 are suitable for the same main body 10 to cooperate with the separate male parts 40 and 46. Is shown.

Thus, a separate clamping force can be achieved with only one body part 10, ie, for example, by combining the male part 40 on one side and the male part 46 on the other side. Industrial applicability
