[Figure 4] FIG. 2 is an enlarged front view of the opening and closing device. [Figure 5] FIG. 10 is a right side view showing the operation of the fastener. [Figure 6] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0015] "overview" FIG. 1 is a perspective view of a fastener 100 according to an embodiment. The fastener 100 according to the embodiment is a one-piece molded product made of plastic. This fastener 100 comprises a C-shaped frame body 10, a bridge portion 30 provided between both ends of the frame body 10, and a fastener portion 50 attached to the frame body 10. This hanging device 100 is used, for example, when hanging the frame body 10 from a D-ring of a bag, or when hanging various articles from the hole 50a of the hanging portion 50 via an S-ring.

[0016] "detail" (Frame body 10) Fig. 2 is a front view of the fastener 100, and Fig. 3 is a cross-sectional view of the frame main body 10. In the following description, "upper," "lower," "left," and "right" refer to the directions shown in Fig. 3. In Fig. 3, the direction toward the center of the fastener 100 or the side closer to the center is referred to as "inner," and the direction away from the center of the fastener 100 or the side farther away from the center is referred to as "outer."

[0017] The frame body 10 extends in a C-shape, with a first end 10a and a second end 10b, which are ends in the extending direction, facing each other at a predetermined distance. Specifically, the frame main body 10 includes a first semicircular arc portion 10A having a concave bottom, a linear portion 10B having its upper end connected to the left end of the semicircular arc portion 10A and extending downward, and a second semicircular arc portion 10C having its left end connected to the lower end of the linear portion 10B and having a concave top. The right end of the first semicircular arc portion 10A is the first end portion 10a, and the right end of the second semicircular arc portion 10C is the second end portion 10b. The first end portion 10a and the second end portion 10b face each other at a predetermined distance in the vertical direction, and a bridge portion 30 (described below) is provided between them.

[0018] The frame body 10 has a wide base plate 11a and ribs 11b and 11c formed on both edges thereof, protruding from the front and back, forming an H-shaped cross section. Rib 11b is a rib on the inner edge of the frame body 10, and rib 11c is a rib on the outer edge of the frame body 10. The provision of these ribs 11b and 11c increases the strength of the frame body 10 and also increases the rigidity of the frame body 10 in the inward and outward directions. The frame body 10 has elasticity in the direction perpendicular to the wide surface of the base plate 11a.

[0019] (Bridge section 30) FIG. 4 is an enlarged front view of the bridge portion 30. As shown in FIG. The bridge portion 30 is suspended between the first end 10a and the second end 10b of the frame main body 10. The bridge portion 30 is composed of a first engagement portion 31 attached to the first end 10a and a second engagement portion 32 attached to the second end 10b. The second engagement portion 32 and the first engagement portion 31 are juxtaposed in the inward / outward direction of the frame main body 10 to open a passage, and are separated from each other in a direction perpendicular to the wide surface of the base plate 11a to close the passage.

[0020] The first engagement portion 31 forms a hook-shaped portion (first hook-shaped portion) and includes a first support portion 31a whose base end is connected to the first end portion 10a of the frame main body 10, and a first protrusion portion 31b which is connected to the tip of the first support portion 31a and protrudes inward. The first support portion 31a has a width approximately half that of the frame main body 10. The base end of the first support portion 31a is joined to the outer surface of the first end portion 10a and extends parallel to the linear portion 10B. A radius (R) is provided between the first support portion 31a and the first end portion 10a. The first protruding portion 31b is bent inward at a right angle to the first support portion 31a. The first protruding portion 31b does not have to be bent at a right angle to the first support portion 31a. It may be bent in a V-shape or an arc shape. The entire first engagement portion 31 may be curved. Furthermore, a protrusion 31c having a surface flush with the end face of the first end 10a is formed on the inside of the first end 10a. This protrusion 31c (first portion) is disposed opposite a second protruding portion 32b (second portion) including an inwardly protruding portion 32c on the inside of the frame main body 10 (see FIG. 4). By providing the protrusion 31c (first portion), even when an external force acts on the second semicircular arc portion 19c from the diagonally lower right in FIG. 2, the second protruding portion 32b (second portion) abuts against the protrusion 31c, thereby maintaining the engagement between the first engaging portion 31 and the second engaging portion 32. By providing this first engaging portion 31, the first protruding portion 31b, the first supporting portion 31a, the first end portion 10a, and the protrusion 31c form a first recess R1. Furthermore, the side facing the second protruding portion 32b including the protrusion 31c of the first end and the portion 32c protruding inward is formed parallel to each other.

[0021] The second engagement portion 32 forms a hook-shaped portion (second hook-shaped portion) and includes a second support portion 32a whose base end is connected to the second end portion 10b of the frame main body 10, and a second protrusion portion 32b which is connected to the tip of the second support portion 32a and protrudes outward. The second support portion 32a has a width approximately half that of the frame main body 10. The base end of the second support portion 32a is joined to the inner surface of the second end portion 10b, and extends parallel to the straight portion 10B. A radius (R) is provided between the second support portion 32a and the second end portion 10b. The second protruding portion 32b is bent outward at a right angle to the second support portion 32a. The second protruding portion 32b does not have to be bent at a right angle to the second support portion 32a. It may be bent in a V-shape or an arc. The entire second engagement portion 32 may be curved. By providing this second engaging portion 32, the second protruding portion 32b, the second supporting portion 32a, and the second end portion 10b form a second recessed portion R2.

[0022] FIG. 5 is a right side view illustrating the operation of the fastener 100. FIG. In the normal state, the bridge portion 30 is arranged side by side in a plane on the inside and outside, closing the passage, due to the elastic force of the frame main body 10. That is, in the normal state, the bridge portion 30 is arranged such that the first protruding portion 31b enters the second recessed portion R2 and the second protruding portion 32b enters the first recessed portion R1 due to the elastic force of the frame main body 10 (FIG. 5(A)). When an external force is applied to the fastener 100 in this state, the first protruding portion 31b and the second protruding portion 32b come into contact with the recess wall, maintaining the passage closed. Furthermore, when forces are applied manually in opposite directions perpendicular to the main surface, the first engagement portion 31 and the second engagement portion 32 move in directions that move them away from each other, and a passage is opened between the first engagement portion 31 and the second engagement portion 32 (Figure 5(B)).

[0023] (Latching part 50) FIG. 6 is an enlarged front view of the hook portion 50. As shown in FIG. The hook portion 50 is an auxiliary hook portion and is attached to the lower end of the frame main body 10. The hook portion 50 protrudes downward like a tongue from the frame main body 10. The hook portion 50 has a D-shaped hole 50a that bulges downward. The hooking portion 50 is configured as a frame having an H-shaped cross section similar to the frame body 10, and a rib 51c on the outer edge of the frame is connected to a rib 11c on the frame body 10. Furthermore, a rib 51b on the inner edge forms the edge of the hole 50a. The width of the joint between the hooking portion 50 and the frame main body 10 is larger than the width of the hole 50a. In addition, the joint between the hooking portion 50 and the frame main body 10 is rounded. Various objects can be hung from this hanging portion 50 via, for example, an S-hook or the like.

[0024] Effects of the embodiment The above-described fastener 100 provides the following advantages. First, the number of parts required for fastener 100 is small and it can be manufactured inexpensively because first engaging portion 31 and second engaging portion 32 close the passage due to the elasticity of frame body 10. In particular, because fastener 100 is integrally molded from plastic, assembly of fastener 100 is not required, making it possible to realize an inexpensive fastener 100. Secondly, when the first engagement portion 31 and the second engagement portion 32 of the fastener 100 are closed, there is no need to keep the first engagement portion 31 and the second engagement portion 32 in contact with each other, so there is no need to perform tasks such as separating the first engagement portion 31 and the second engagement portion 32 after removing them from the mold. Thirdly, the cross section is constructed using an H-shaped frame, making it very strong. Fourth, the frame body 10 has an H-shaped cross section, and the wide surface (main surface) of the base plate 11a faces forward, so the fastener 100 is less likely to bend inward or outward. This results in a structure in which a D-ring or the like attached to the frame body 10 will not easily come off. Fifth, the base end of the first support portion 31a of the first engagement portion 31, which has a first protrusion portion 31b protruding outward, is joined to the inner surface of the first end portion 10a, and the base end of the second support portion 32a of the second engagement portion 32, which has a second protrusion portion 32b protruding inward, is joined to the outer surface of the second end portion 10b.This allows the lengths of the first protrusion portion 31b and the second protrusion portion 32b to be increased, and accordingly the contact surfaces of the first protrusion portion 31b and the second protrusion portion 32d can be increased, resulting in a structure that is resistant to tensile forces. Sixth, by providing the protrusion 31c, the first recess R1 becomes deeper, making it difficult for the first engagement portion 31 and the second engagement portion 32 to come off, and by having a string or the like hung on the frame half 10 get caught on the protrusion 31c, it is possible to prevent the string or the like from coming off unintentionally. Seventh, the frame is configured to have an H-shaped cross section, and various parts are rounded, making it possible to realize fastener 100 that is less likely to break as a whole. Eighth, since the first recess R1 penetrates the front and back of the first engagement portion 31 and the second recess R2 penetrates the front and back of the second engagement portion 32, the contact surface is enlarged when an external force is applied, making it more difficult for the first engagement portion 31 and the second engagement portion 32 to separate.

[0025] <<Variation>> In the above embodiment, the hook portion 50 is attached to the frame body 10, but the hook 100 can also be configured with just the frame body 10 and the bridge portion 30.

[0026] In addition, in the embodiment, the first engagement portion 31 and the second engagement portion 32 are configured to be able to be separated and brought into contact with each other in a direction perpendicular to the extension surface of the frame main body 10, but the first engagement portion 31 and the second engagement portion 32 may also be configured to be able to be separated and brought into contact with each other in the inward and outward directions of the frame main body 10.

[0027] Furthermore, in the above embodiment, the case of the C-shaped frame body 10 has been described, but the present invention can also be applied to an incomplete loop-shaped frame body having a partial missing portion other than a C-shape.

[0028] Furthermore, in the above embodiment, the holes formed by the frame main body 10 and the bridge portion 30 and the hole 50a of the hooking portion 50 are provided independently, but a slit connecting the two may be provided in the frame main body 10. In this way, it becomes possible to hang a looped string or the like on the frame of the hooking portion 50.

[0029] In the above embodiment, the case where the hook portion 50 is used with the bottom facing down has been described, but the hook portion 50 can also be used with the top facing up. The same applies when the hook 100 is configured with only the frame body 10 and the bridge portion 30.

[0030] Furthermore, in the above embodiment, the hooking portion 50 is provided on the outside of the frame main body 10, but the hooking portion 50 may be provided on the inside of the frame main body 10. Also, the hooking portion 50 may be provided on the first semicircular arc portion 10A side, or on both the first semicircular arc portion 10A and the second semicircular arc portion 10C.
