Embodiment Construction

[0035] Embodiments of the present invention will be described below with reference to the drawings.

[0036]

[0037] Figure 1 to Figure 4 It is a figure which shows the connection ring of this invention. The coupling ring 1 of the present embodiment is an annular coupling tool for attaching keys and various small items to clothes, bags, and the like.

[0038] The coupling ring 1 has a substantially C-shaped main body 10 in plan view, and a vertically long rod-shaped closing portion 20 rotatably attached to the main body 10 .

[0039] The main body 10 has an opening 11 in which a part of the circumferential direction is notched, and the main body 10 is formed of synthetic resin into a substantially C-shape in plan view.

[0040] As the synthetic resin, polyacetals such as polyoxymethylene, polyethylene, polypropylene, and the like are preferably used. In particular, polyacetal resins widely used as a substitute for metals are preferable from the viewpoint of strength.

Abstract

The present invention provides a connecting ring which does not harm appearance and can improve manufacturability. The connecting ring (1) is provided with the following components: a body (10) which is provided with an opening (11) and is formed to an approximate C-shaped member by synthetic resin; and a closing part (20), wherein one end (20A) in a length direction is axially supported on the body (10) through a rotatable mode, and the other end (20B) in a length direction rotates in a contactable / separatable mode relative to the body (10), thereby opening / closing the opening (11). One end (10A) of the body (10) at the opening (11) is provided with an axial supporting part (12) which axially supports the closing part (20) through a rotatable mode. An arc-shaped elastic sheet (15) projects integrally at a position on the body (10), which is provided a position of an internal circumference (10C) when compared with the axial supporting part (12). The elastic sheet is thinned to the front end. The elastic sheet (15) elastically presses the other end (20B) of the closing part (20) from the internal circumference (10C) to the outer circumference (10D) of the body (10). Mutually separated incised notches (16) are provided between the axial supporting part (12) and the elastic sheet (15). The elastic sheet (15) is accommodated in the closing part (20). Furthermore the closing part (20) is provided with an elongated dent part (25) for abutting against the front end of the elastic sheet (15).

Description

technical field [0001] The present invention relates to a coupling ring in which a closing portion for opening and closing the opening is rotatably attached to a C-shaped main body having an opening. Background technique [0002] In recent years, fastening rings imitating carabiners used in mountaineering have been widely used as fastening parts for attaching keys and various small items to clothes, bags, and the like. [0003] Such a connecting ring adopts a structure in which one end in the longitudinal direction is pivotally supported in a rotatable manner to open the opening, and is attached to a substantially C-shaped main body in plan view having an opening partially cut in the circumferential direction. Closed closing parts (for example, refer to Patent Documents 1 and 2). [0004] In particular, when used as a link for attaching keys and small items, since it is used for decorative purposes like accessories, it does not require the strength required for mountain cli...
