The present invention can be detachably combined with a coupling strap that is bound to a portable product such as a mobile phone, MP3 player (MP3 player), and a hanger that can be hung on the user's neck, etc. Not only this is possible, but it is related to a multi-purpose ring connector, so that the other side is not twisted with each other by allowing the other side to be rotatable with respect to one side in a coupled state.

With the development of electronic technology, various small electronic products such as mobile phones, MP3 players, digital cameras, and the like have been developed. Recently, these products have been commercialized, and thus, a means to conveniently carry various small products has been needed.

However, although the small electronic products as described above are large enough to fit in a pocket, it is inconvenient to store various portable items including keys in a pocket or a separate bag.

In addition, the small electronic products are often inconvenient for users because it is frequently used and repeated in the storage space, such as a bag or a separate bag, because the frequent use operation is repeated.

Therefore, in order to solve the above problems, various portable strings have been developed that can be hung around the neck using a string.

Conventional portable line is composed of a loop that is connected to one side of the portable product, a rope forming a closed loop to hang on the user's neck, and a connector for connecting the loop and the cord, the portable product is bound to the loop By carrying the string in a state of being hooked to a user's hand or neck in a state, it is not only easy to carry, but also has an advantage that a portable product can be used immediately in the state of carrying.

However, the portable string has a fixed length, and when the portable article is to be used at a distance away from the user's body, the portable string must be separated from the user's hand or neck, and then used. There was a hassle to carry again walking on the user's hand or neck.

In order to solve the above problems, one portable line is separated into two, and the 'cell phone line' that allows two lines to be detachably combined as a connector has been published in Korean Utility Model Publication No. 1998-024836.

The cell phone strap, the main body strap that one side is bound to the mobile phone; A fastening strap for hanging on the waist belt; A stone main body coupled to the other side of the main body string; Consists of a groove body coupled to one side of the fixing line, the locking main body is caught in the locking groove of the groove body after the stone main body is inserted into the groove body.

At this time, when the groove body and the stone base body are to be separated, the locking protrusion of the stone base body is released by pressing the release groove, and then the groove body is pulled out.

Cell phone strap of the above structure is convenient to carry, as well as the waist belt of the user's neck when the fixed strap is lengthened, as well as convenient to carry, combined with the main body and the stone base body There is an advantage that can be used to separate only portable items such as mobile phones by releasing.

However, in the case of the above structure, because the locking projections are exposed to the outside, even if the user does not want to separate, the locking projections can be easily separated by pressing the external force. In addition to the inconvenience to be combined, there is a disadvantage in that the main body and the fixed line twisted because the main body can not be rotated with respect to the groove body in the combined state.

The present invention has been devised to solve all the problems of the conventional portable cords and various connection strings, and the two separate lines, that is, a pair of connecting objects can be detachably connected, regardless of the direction. The present invention provides a multi-purpose ring connector that can be easily combined and freely rotates on the other side in a coupled state so that two strings or strings connected to each other can not be twisted together by rotation. There is a purpose.

The above object of the present invention is achieved by an insert having two faces parallel to each other on a cross section and an insert having an inner circumferential surface of a circular cross section.

The multi-purpose ring connector of the present invention, while the insertion can be combined to be separated from each other in all directions 360 ° instead of a constant direction about the insertion direction axis, while one side is freely rotated relative to the other in the coupled state structural features There is this.

Multi-purpose ring connector of the present invention as described above, the inserts formed with protrusions projecting on each side in the width direction; A stepped portion protrudes from the inner circumferential surface open end, and is composed of an insert having an inner circumferential surface having a circular cross section.

The insert has a shape with a relatively small thickness dimension compared to the width and length dimensions, and the figure circumscribed to the cross section in the width direction is about twice as long as the length of the other two sides parallel to each other is relatively longer than the two sides parallel to each other. To form a rectangle. In other words, in terms of circumscribed figure, it has a flat structure.

In this case, it is preferable to have a curvature rather than a straight line perpendicular to the long side in order to smoothly rotate even when the insert contacts the inner circumferential surface of the insert described below.

And, the insert can be made of a material of various shapes such as plate, wire, etc., the important thing is that the figure circumscribed in the cross-section in the width direction must form a rectangle, in particular, by processing the material of the wire or similar shape If the insert is made, it means that the wire rod forming the insert must be machined on the same plane.

In addition, the both sides in the width direction of the insert is a structure provided with locking projections, respectively.

The insert is a body into which the insert is inserted and coupled, and has an inner space having an inner circumferential surface having a circular cross section and having an insertion hole penetrating the inside and the outside, and having a ring-shaped stepped portion protruding from the lower end of the inner space. The inner diameter of the part serves as the insertion hole.

That is, the inner space of the insert into which the insert is inserted has an inner circumferential surface of a circular cross section, the inner diameter of which is not smaller than the maximum width of the insert including the locking protrusion, but the inner diameter of the stepped portion is smaller than the maximum width of the insert, The locking projections of the inserted inserts are caught by the stepped portions of the inserts, and both of them are coupled, and the inserts can be freely rotated in the direction of the circular inner circumferential surface of the inserts.

At this time, the insert having a maximum width larger than the inner diameter of the stepped portion as described above, in order to be coupled or separated into the insert, the elastic deformation of any one side must be possible.

For example, when the insert is made of a material that is difficult to elastically deform, the insert is made of a soft material that is elastically deformable, and a force is applied while the insert is in close contact with the open end of the insert. By pressing, the open end of the insert is elastically deformed and the insert can be inserted into the insertion hole.When the insert is separated, both sides of the open end of the insert corresponding to the direction orthogonal to the width direction of the insert are removed. Pressing the outer circumferential surface, the open end is deformed long in the width direction of the insert can be pulled out.

Alternatively, in contrast to the above, the insert and the insert may be manufactured. In this case, the insert may be elastically deformed and coupled and separated, and both sides may be made of a material capable of elastic deformation.

Details of the object and technical configuration of the present invention and the resulting effects thereof will be clearly understood by the following detailed description with reference to the drawings showing preferred embodiments of the present invention.

1 is an exploded perspective view of the multi-purpose ring connector of the present invention in FIG. 1, an exploded perspective view in FIG.

As shown the multi-purpose ring connector of the present invention,

An insert 11 having a ring-shaped stepped portion J having an insertion hole H formed at a lower end of the inner circumferential surface S of the inner space R having a circular cross section;

Free rotation is possible in the state inserted into the internal space (R) of the insert 11 through the insertion hole (H) of the insert 11, the cross section in the width direction inscribed or coincided with the inside of the rectangle, The locking projection E caught on the stepped portion J of the insert 11 is composed of an insert 12 or the like protruding on both outer surfaces of the width direction.

At this time, the maximum width of the insert 12 including the locking protrusion E is not larger than the inner diameter R of the insert 11 and the inner diameter of the insertion hole H, which is the inner diameter of the stepped portion J, at the same time. Is greater than

Then, in order to prevent the insert 12 from being excessively upwardly inserted along the insertion direction in the internal space R of the insert, the stepped jaw portion J in which the projection E of the insert 12 is located. It is also preferable to make the diameter of the inner space R beyond the uppermost portion smaller than the maximum width of the insert 12.

That is, the insert 12 inserted into the interior space R of the insert 11 cannot enter the upper portion of the interior space R having an inner diameter smaller than its maximum width.

The outer shape of the insert 11 constituting the multi-purpose ring connector of the present invention as described above may be made in a variety of shapes, regardless of the outer shape of the inner space (R) must have a circular cross section, The other end facing the insertion hole (H) may be open or blocked structure.

And, the insert 12 can also be made in various shapes, for example, as shown in FIGS. 1 and 2 above,

A ring member 12A connected to one side and the like;

Insertion member which is extended forward from one open end of the ring member (12A) and then bent 180 ° to be connected to the other open end of the ring member (12A), the engaging projection (E) is provided on both sides in the width direction, respectively It can comprise with 12B.

At this time, the coupling protrusion E is positioned approximately at the central portion in the longitudinal direction of the insertion member 12B, and the length of the insertion member 12B inserted into the internal space R of the insert 11 is determined by the internal space R. By making it almost equal to the length, the insertion member 12B inserted into the internal space R of the insert 11 may be prevented or minimized from excessively flowing in the direction opposite to the insertion direction.

In this case, there is no need to partially reduce the inner diameter of the inner space R to prevent excessive entry of the insertion member 12B or flow in the direction opposite to the insertion direction.

In addition, as shown in Figure 4, the engaging projections (E) are provided on both sides of the plate-shaped one end end insertion member (12B), respectively, and penetrates the upper and lower surfaces through the central portion of the ring member (12A) of the other end plate Since various shapes, such as being manufactured in the structure in which the connection hole H 'was formed, are possible, it is important to make the geometric shape which circumscribes the cross section of the width direction into flat form, ie, rectangular form.

Multi-purpose ring connector of the present invention configured as described above can be changed in various forms, for example, as shown in Figures 5 to 7, the stepped portion (J) between the ring member 12A and the insertion member 12B And the upper surface of the stepped portion J is caught by the lower surface of the insert 11, that is, the bottom surface of the stepped portion J provided in the insert 11.

In addition, the inner space R of the insert 11 corresponds to the large-diameter locking projection counterpart R1 and the upper insertion member 12B1 located immediately above the locking projection E in the upward direction. The upper insertion member corresponding portion R2 of the medium diameter and the free space portion R3 of the small diameter are divided and formed, and the upper surface of the inserted object 11 and the clearance gap (R3). It is also preferable to provide a through hole (H ") through the ceiling surface of the).

At this time, the inner diameter decreases in the order of the locking projection counterpart R1, the upper insertion member counterpart R2, and the clearance gap R3.

The locking protrusion corresponding part R1 is a space in which the locking protrusion E of the insert 12 rotates, and the upper inserting member corresponding part R2 is formed by the upper inserting member 12B1 of the insert 12. It is a space to be located.

At this time, by making the inner diameter of the upper insert-member-corresponding portion R2 not smaller than the width of the upper insert 12B1 of the insert 12, the insert 12 flows inside the insert 11. Can be minimized.

The free space portion R3 is a space in which a knot K, such as a string, is connected to the internal space R of the insert 11 through a through hole H ″ from the outside.

As described above, the multi-purpose ring connector of the present invention is very easy to insert the insert and the insert because the insert can be freely inserted into the insert in all directions without rotating the insert in a specific direction In addition, since the insert is freely rotated in the insert in a combined state, twisting of two members to be connected, such as a string, is prevented, thereby improving aesthetics when carrying.
