Hanging tool

Abstract

To provide a hanging tool which is inexpensive and hard to be detached.SOLUTION: A bridge which is provided between a first end and a second end of a frame main body in an imperfect loop shape comprises a first engagement part, which is provided additionally in the first end and in which a first recess is formed, and a second hook-shaped part which is provided additionally in the second end and in which a second recess is formed. In a state where the first engagement part and a second engagement part are proximate to each other, a portion of the first engagement part enters the second recess and a portion of the second engagement part enters the first recess, thereby closing a passageway. The frame main body is elastically deformed by a manual action, such that the first engagement part and the second engagement part are separated and the passageway is opened. When a predetermined external force acts, the first engagement part and the second engagement part are partially abutted with a recess wall, thereby maintaining a state where the passageway is closed.SELECTED DRAWING: Figure 2

[0018] [Figure 1] FIG. 2 is a perspective view of the fastener according to the embodiment. [Diagram 2] FIG. [Diagram 3] FIG. 4 is a cross-sectional view of the frame of the main body. [Figure 4] FIG. 2 is an enlarged front view showing the opening and closing device. [Diagram 5] FIG. 11 is a right side view showing the operation of the fastener. [Figure 6] FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0020] "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. The 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.

[0021] "detail" (Frame body 10) Fig. 2 is a front view of the hanging device 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 hanging device 100 or the side closer to the center is referred to as "inner", and the direction away from the center of the hanging device 100 or the side farther from the center is referred to as "outer".

[0022] 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 body 10 includes a first semicircular arc portion 10A with a concave downward shape, a straight portion 10B whose upper end is connected to the left end of the semicircular arc portion 10A and extends downward, and a second semicircular arc portion 10C whose left end is connected to the lower end of the straight portion 10B and whose upper end is concave. 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.

[0023] The frame body 10 is a frame with an H-shaped cross section, with ribs 11b, 11c protruding from both edges of a wide base plate 11a. 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. Providing these ribs 11b, 11c increases the strength of the frame body 10 and 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.

[0024] (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 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 inside-outside direction of the frame 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.

[0025] 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 straight portion 10B. An 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 bent. 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. By providing this protrusion 31c, even when an external force acts on the second semicircular arc portion 19c from the diagonally lower right in FIG. 2, the second protrusion 32b abuts against the protrusion 31c, so that the engagement between the first engagement portion 31 and the second engagement portion 32 is maintained. By providing this first engagement portion 31, a first recess R1 is formed by the first overhanging portion 31b, the first support portion 31b, the first end portion 10a, and the protrusion 31c.

[0026] 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 second support portion 32a has a base end connected to the inner surface of the second end portion 10b and extends parallel to the straight portion 10B. An 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 shape. The entire second engagement portion 32 may be bent. By providing this second engagement portion 32, a second recess R2 is formed by the second protruding portion 32b, the second support portion 32a, and the second end portion 10b.

[0027] 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 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 in a state in which 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. In addition, when forces in opposite directions perpendicular to the main surfaces are applied manually, the first engagement portion 31 and the second engagement portion 32 move in directions away from each other, and a passage is opened between the first engagement portion 31 and the second engagement portion 32 (Figure 5(B)).

[0028] (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 portion 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 hook portion 50 is configured with 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 of the frame body 10. Also, a rib 51b on the inner edge forms the edge of a hole 50a. The width of the joint between the hook portion 50 and the frame body 10 is larger than the width of the hole 50a. Also, the joint between the hook portion 50 and the frame body 10 is rounded. Various items can be hung from this hanging portion 50 via, for example, an S-hook or the like.

[0029] Effects of the embodiment The above-described fastener 100 provides the following advantages. First, the number of parts required for the hanging device 100 is small and it can be manufactured inexpensively because the first engagement portion 31 and the second engagement portion 32 close the passage due to the elasticity of the frame body 10. In particular, since the hanging device 100 is integrally molded from plastic, assembly of the hanging device 100 is not required, and therefore an inexpensive hanging device 100 can be realized. Secondly, since there is no need to keep the first engagement portion 31 and the second engagement portion 32 of the fastener 100 in abutment when the first engagement portion 31 and the second engagement portion 32 are closed, there is no need to perform tasks such as separating the first engagement portion 31 and the second engagement portion 32 after removing from the mold. Thirdly, the cross section is constructed using an H-shaped frame, making it very strong. Fourthly, 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 unlikely 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, since 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 10a, the lengths of the first protrusion portion 31b and the second protrusion portion 32b can be increased, and accordingly the abutment surface 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 causing a string or the like hung on the frame half 10 to get caught on the protrusion 31c, it is possible to prevent the string or the like from coming off unintentionally. Seventh, by configuring the frame so that its cross section is H-shaped and by providing radiuses at 8 in various places, fastener 100 as a whole is less likely to break. Eighth, since the first recess R1 penetrates from the front to the back of the first engagement portion 31, and the first recess R2 penetrates from the front to the back of the second engagement portion 32, the contact surface is enlarged when an external force is applied, and accordingly, the first engagement portion 31 and the second engagement portion 32 are less likely to separate from each other.

[0030] <<Variation>> In the above embodiment, the hook portion 50 is attached to the frame body 10, but the hook 100 can also be formed by only the frame body 10 and the bridge portion 30.

[0031] 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 extending 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.

[0032] 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 a frame body having an incomplete loop shape other than a C-shape, which has a partially missing portion.

[0033] Furthermore, in the above embodiment, the hole formed by the frame main body 10 and the bridge portion 30 and the hole 50a of the hook 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 loop-shaped string or the like on the frame of the hook portion 50.

[0034] In the above embodiment, the hook 50 is used with the hook portion 50 facing downward, but the hook portion 50 can also be used with the hook portion 50 facing upward. The same applies when the hook 100 is composed of only the frame body 10 and the bridge portion 30.

[0035] Furthermore, in the above embodiment, the hook portion 50 is provided on the outer side of the frame main body 10, but the hook portion 50 may be provided on the inner side of the frame main body 10. Also, the hook 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.
