At this time, since the first linking member 110 and the second linking member 120 are pulled together by the elastic body 160, the balance between the first linking member 110 and the second linking member 120 Distance is maintained.

The first head 141 of the first stop pin 140 is inserted into the first insertion groove 114 at a position where the horizontal distance between the first insertion groove 114 and the second insertion groove 124 is the farthest The distance between the first adjusting end 113 and the second adjusting end 123 is minimized when the second head 151 of the second stop pin 150 is inserted into the second insertion groove 124, The first connector 110 and the second connector 120 are in the closest state to each other.

At this time as well, since the first connector 110 and the second connector 120 are pulled by the elastic body 160, the first connector 110 and the second connector 120 ) Is maintained.

In order to adjust the distance between the first linking member 110 and the second linking member 120, this is accomplished by rotating the gripping member 130 against the first linking member 110 and the second linking member 120 .

This will be described in more detail as follows.

In a state in which the first head 141 of the first stop pin 140 is inserted into any one of the first insertion grooves 114 arranged on the first adjustment end 113 (the external force more than the elastic force of the elastic body 160 The first body 142 fixed to the grip 130 moves together with the grip 130 when the grip 130 is rotated with respect to the first link 110, (S2).

At this time, the first elastic restoring arm 143 flexes and stores the elastic force.

The first head 141 is pulled out of the original first insertion groove 114 and inserted into another adjacent first insertion groove 114 and the first elastic restoring arm 143 ) Is elastically restored.

And the second head 151 of the second stop pin 150 is inserted into any one of the second insertion grooves 124 arranged on the second adjustable end 123 in a state where the elastic force of the elastic body 160 The second body 152 fixed to the grip 130 moves together with the grip 130 when the grip 130 is rotated with respect to the second link 120, And is rotated based on the rotation axis S3.

At this time, the second elastic restoring arm 153 flexes and stores the elastic force.

The second head 151 is pulled out of the original second insertion groove 124 and inserted into the adjacent second insertion groove 124 and the second elastic restoring arm 153 ) Is elastically restored.

This allows the first stop pin 140 to move along the first adjustable end 113 and move the second stop pin 150 along the second adjustable end 123, The distance between the connecting body 110 and the second connecting body 120 can be adjusted.

The locking device 100 according to the present invention may further include an auxiliary pipe 170. The auxiliary pipe 170 is formed in the shape of a circular tube and the elastic body 160 is inserted into the auxiliary pipe 170 It can be made to act elastically.

Hereinafter, a method of using the travel bag 2 and the handle length adjusting device 1 according to the present invention will be described.

In order to allow the first rod 20 and the second rod 30 to move smoothly in the vertical direction with reference to the joined body 10, (Refer to FIGS. 4A and 4B), and the adjustment is made such that the degree of rotation of the gripper 130 with reference to the first connector 110 and the second connector 120 Lt; / RTI >

That is, the grip 130 is appropriately rotated to adjust the distance between the first connector 110 and the second connector 120 so that the first and second rods 20 and 30 are parallel to each other .

In this state, the frictional force acting between the first rod 20 and the second rod 30 and the coupling body 10 is minimized.

On the other hand, when it is not necessary to use the handle (the grip portion 130), the first rod 20 and the second rod 30 may be located at the lowest position relative to the combined body 10, 1) is coupled to the main body of the travel bag 2, the handle (grip portion 130) is preferably positioned adjacent to the upper end of the main body.

When it is necessary to use the handle (the grip portion 130), the first rod 20 and the second rod 30 are drawn out to the upper side of the assembled body 10 (see Fig. 4 (b)).

Next, in order to fix the handle (grip 130) at an arbitrary height, the grip 130 is rotated with respect to the first link 110 and the second link 120 to one side. For example, the grip 130 may be rotated so that the first link 110 and the second link 120 are spaced apart from each other (see FIG. 4 (c)), The grip portion 130 can be rotated so that the second link members 120 are brought close to each other. At this time, the first rod 20 and the second rod 30 may be slightly bent or bent.

In the former case, the opposite surface of the second rod 30 of the outer circumferential surface of the first rod is firmly brought into close contact with the first friction ring 12, and the opposite surface of the outer circumferential surface of the second rod 20 is connected to the second friction ring 12 The first rod 20 and the second rod 30 are prevented from moving in the vertical direction with respect to the coupling body 10 and the fixing of the handle (the grip portion 130) at an arbitrary height .

In the latter case, the surface of the outer peripheral surface of the first rod facing the second rod 30 is strongly pressed against the first friction ring 12, and the surface of the outer peripheral surface of the second rod facing the first rod 20 is pressed against the second friction ring 12 The first rod 20 and the second rod 30 are prevented from moving in the vertical direction with respect to the coupling body 10 while being firmly brought into close contact with the fastening portions 13 .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious to those who have. Accordingly, it should be understood that such modifications or alterations should not be understood individually from the technical spirit and viewpoint of the present invention, and that modified embodiments fall within the scope of the claims of the present invention.
