Description

Key ring {A key ring}

The present invention relates to a key ring, and more particularly to a key ring for convenient insertion / removal of the key on the key ring.

Typically, the key ring is formed by winding a material having excellent elastic force several times in a ring shape, and stores a plurality of keys through the end of the ring.

However, since the end of the ring is held close to the ring body by a strong elastic force and does not open easily, it takes considerable power and time when inserting / removing the key, especially for the weak and weak old people who own the key ring. I couldn't use it because I couldn't use it.

Therefore, in the conventional Patent Publication No. 10-2005-0092098, a rotating body made up of a part of a ring-shaped body is installed so as to pivot simply by simply pushing the rotating body, various keys are simply caught and at the same time, the rotating body is automatically retracted and ring-shaped. Maintaining the ring shape of the main body, on the contrary, when the keys are separated, a simple opening of the opening simply by pressing the rotating body with a finger, and various technologies have been disclosed to make it very easy to withdraw.

However, the key ring is installed inside the rotating body in order to return the rotating body installed to swing on the ring-shaped body after the rotation, the number of parts is increased due to the leaf spring to increase the manufacturing Caused.

In addition, it is difficult to manufacture because the leaf spring is to be more compact to fit a small key ring, and in particular, in order to fix the leaf spring on the ring-shaped body, a separate work process and a dedicated machine were additionally prepared.

Accordingly, the present invention has been conceived to solve the above-mentioned problems, and more particularly, the object of the present invention is to provide a key ring that allows a user to easily insert / remove a key by simple configuration and easy operation.

Features of the present invention to achieve this purpose, the key ring body 10 is formed to be in close contact with each other by winding the elastic wire 12 in the form of a coil; And a rotating ring coupled to the wire end of the key ring body 10 by a hinge 22 to be pivoted, and having one surface closely contacted on the key ring body 10 by the adhesion between the elastic wires 12 ( 20); characterized in that comprises a.

At this time, the support protrusion 24 is formed to extend at the end of the rotating ring 20 adjacent to the hinge 22, the receiving groove 14 on the key ring ribbon 10 corresponding to the support protrusion 24. It is characterized in that it is formed.

In addition, the position fixing groove 26 is formed on the rotary ring 20, and the position fixing jaw 16 on the key ring body 10 corresponding to the position fixing groove 26 is provided to be engaged with each other. It features.

According to the above configuration and operation, the present invention is rotated around the hinge when inserting / removing the key as the distance from the elastic wire is spaced apart from the elastic wire, anyone can easily and easily insert / remove the key on the key ring It can work.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a key ring as a whole according to the present invention, Figure 2 is a block diagram showing a state in which the key is inserted into the key ring according to the present invention, Figure 3 is a key ring according to an embodiment of the present invention Figure 4 is a block diagram showing the support projection and the receiving groove, Figure 4 is a block diagram showing the position fixing jaw and the position fixing groove of the key ring according to another embodiment of the present invention.

The present invention relates to a key ring, in which the key ring is made of a main configuration including the key ring body 10, the rotating ring 20 so that the insertion / separation of the key is easy and simple.

Key ring body 10 according to the present invention is formed to be in close contact with each other by winding the elastic wire 12 in the form of a coil. The key ring body 10 is wound around the elastic wire member 12 having excellent elastic force including a steel wire in the form of a circular, square, streamlined coil several times (for example, the elastic wire 12 is overlapped with each other more than one lap). 1) is formed by winding, but Figure 1 shows a state in which the elastic wire 12 is wound in a circle about half a circle.

At this time, since the elastic wire 12 is separated by the overlapping portions of the elastic wire 12 by close contact with each other by applying an external force, the elastic wire 12 must be spaced between the elastic wire 12 when inserting / removing the key K on the key ring body 10. Has a structure that must be opened with steel.

In addition, the rotating ring 20 according to the present invention is installed to be pivotally coupled to the hinge 22 at the end of the elastic wire 12 of the key ring body 10, one side of the key by the adhesion between the elastic wire 12. It is provided to be in close contact with the ring body (10). Rotating ring 20 is formed in the same shape as the cross-section of the elastic wire 12 is bent in the same shape along the shape of the key ring body (10). That is, Figure 1 shows a state in which the rotating ring 20 is formed in an arcuate shape to match the circular elastic wire 12.

In this way, the rotation ring pivots the hinge to the shaft so that the distance from the elastic wire is easily spaced apart, so that the insertion / removal of the key can be easily performed without forcing the end of the elastic wire to force. In close contact with each other by the elastic force, the rotation ring is also in close contact with the elastic wire to prevent the easy opening.

On the other hand, the elastic wire 12 is preferably engaged with the end of the elastic wire 12 in a negative angle structure as shown in Figure 1 so that the flow is prevented in the direction except the turning direction while the hinge 22 is pivoted on the axis. Do.

In addition, the support protrusion 24 is formed to extend at the end of the rotating ring 20 adjacent to the hinge 22, the receiving groove 14 on the key ring body 10 corresponding to the support protrusion 24. Is formed. When the rotating ring 20 is pulled, as shown in FIG. 3, the support protrusion 24 pushes the elastic wire 12 by the lever, so that the space between the elastic wires 12 is spaced apart. When the rotation ring 20 is returned after the insertion / removal of the key K is completed, the support protrusion 24 is pushed back to its original position by the return force of the elastic wire 12. In close contact with the wire 12, the flow of the rotating ring 20 during use is prevented.

In addition, the position fixing groove 26 is formed on the rotary ring 20, and the position fixing jaw 16 is provided on the key ring body 10 corresponding to the position fixing groove 26 to be engaged with each other. After the insertion / removal of the key K is completed, the rotary ring 20 returned to its original position is elastic wire rod of the key ring body 10 by the position fixing groove 26 and the position fixing jaw 16 as shown in FIG. 12) is securely positioned by being fitted on the top to prevent flow during use and to prevent damage to the connecting portion joined by the hinge 22 even when an external force is applied on the rotating ring 20.

Figure 2 is a block diagram showing a state in which the key is inserted into the key ring according to the present invention.

Figure 3 is a block diagram showing a support projection and the receiving groove of the key ring according to an embodiment of the present invention.

Figure 4 is a block diagram showing a position fixing jaw and a position fixing groove of the key ring according to another embodiment of the present invention.
