As shown in FIG. 1 to FIG. 5, a plastic clip 100 of the present invention comprises a clip boss 110 integrally formed in a fixed panel 200; and a clip main body 120 detachably assembled to the clip boss 110.

In the clip 100 of the present invention, the clip boss 110 is provided with fitting portions 113 in two lower side portions of a vertical plate 111 wherein a fitting hole 112 is provided; locking projections 114 in front and back upper ends of the fitting portions 113; and support ribs 115 respectively on a front face and a back face of the vertical plate 111.

Also, the clip main body 120 is provided with an inverted triangular input portion 121 in a lower end portion; a locking projection 122 in an upper end portion of the input portion 121; a clip-boss input guide hole 123 in the center of an upper end; a clip-boss input guide portion 124 connected to the clip-boss input guide hole 123 in the center of an internal upper portion; and an elastic fitting piece 125 in a lower end of the clip-boss input guide portion 124.

In the elastic fitting piece 125 of the clip main body 120, one side portion is configured as a fixed end integrally formed in a lower end portion on one side of the clip-boss input guide portion 124, and the other side portion is configured as a free end sealing a lower portion on the other side of the clip-boss input guide portion 124. The elastic fitting piece 125 of the clip main body 120 is provided with a locking projection 125a in a lower end on a free end side.

On the other hand, in an illustrated embodiment, the clip main body 120 is provided with clip-boss support projecting portions 126 on two internal sides of the input portion 121; and a connecting piece 127 between the lower end portion on one side of the clip-boss input guide portion 124 wherein the elastic fitting piece 125 is integrally formed, and the clip-boss support projecting portion 126 on one side.

FIGS. 6 a to 6d are drawings showing a combination process of the clip main body wherein the clip main body is combined with the clip boss in the plastic clip according to one embodiment of the present invention.

In the clip 100 of the present invention, when the clip main body 120 is combined with the clip boss 110 integrally formed in the fixed panel 200, as shown in FIG. 6a, first, after the vertical plate 111 of the clip boss 110 is inserted into the clip-boss input guide portion 124 through the clip-boss input guide hole 123 of the clip main body 120, if a lower end of the vertical plate 111 abuts against the elastic fitting piece 125, the vertical plate 111 is tilted for only a given angle (for example, 15 degrees) to the free end side of the elastic fitting piece 125, and is continuously inserted.

As shown in FIG. 6b, when the lower end of the vertical plate 111, which has passed outside the elastic fitting piece 125, abuts against the clip-boss support projecting portion 126 of the clip main body 120, the vertical plate 111 is tilted in an opposite direction and is continuously inserted. As shown in FIG. 6c, when an end portion of the elastic fitting piece 125 is inserted into the fitting hole 112 at the same time when the lower end of the vertical plate 111 abuts against an internal lower end of the clip main body 120, the vertical plate 111 is vertically raised.

As shown in FIG. 6d, when the vertical plate 111 is vertically raised, the elastic fitting piece 125 completely passes through the fitting hole 112, and the clip-boss support projecting portions 126 provided on the two internal sides of the input portion 121 of the clip main body 120 bilaterally push the vertical plate 111 so as to support the vertical plate 111. Accordingly, the locking projection 125a provided in the lower end on the free end side of the elastic fitting piece 125 is locked in the fitting hole 112, so that even if the vertical plate 111 has flowed in a right-and-left direction, the vertical plate 111 becomes undetached from the elastic fitting piece 125.

Therefore, according to the plastic clip 100 of the present invention, a flowage or noise of the clip main body 120 due to an external impact in a usage process disappears.

On the other hand, as mentioned above, after the clip main body 120 has been combined with the clip boss 110 integrally formed in the fixed panel 200, when the input portion 121 of the clip main body 120 is inserted into a combination hole 310 formed in a combination panel 300, after the input portion 121 of the clip main body 120 has interiorly narrowed to pass the combination hole 310, the input portion 121 of the clip main body 120 restores to its former state again. As a result, as shown in FIG. 4 and FIG. 5, the locking projections 114 provided in the upper end of the fitting portions 113 of the clip boss 110 are locked in an upper end of the combination panel 300, and the locking projection 122 provided in the upper end of the input portion 121 of the clip main body 120 is locked in a lower end of the combination hole 310 so as to be capable of an assembly between the fixed panel 200 and the combination panel 300.

Meanwhile, when the fixed panel 200 is detached from the combination panel 300, if a fastened portion of the plastic clip 100 relative to the fixed panel 200 is pulled to a side opposite to the combination panel 300, the input portion 121 of the clip main body 120 can pass the combination hole 310 while interiorly being narrowed, so that the fixed panel 200 can be pulled out of the combination panel 300.

On the other hand, in a process of detaching the fixed panel 200 from the combination panel 300, if the fastened portion of the plastic clip 100 relative to the fixed panel 200 is pulled, first, the vertical plate 111 of the clip boss 110 integrally formed in the fixed panel 200 is pulled. As a result, the elastic fitting piece 125 of the clip main body 120, which has been inserted in the fitting hole 112 of the vertical plate 111, is pulled, so that the clip main body 120 is pulled. However, at that time, the free end of the elastic fitting piece 125 of the clip main body 120 which is pulled together with the vertical plate 111 contacts the lower end of one side of the clip-boss input guide portion 124. Accordingly, even if the fixed panel 200 is pulled by a slightly unreasonable force, as well as preventing a breakage of the elastic fitting piece 125, a tension force can be stably transmitted to the whole clip main body 120.

The present invention explained above is not limited to the aforementioned embodiment and drawings, and it will be obvious to those having an ordinary skill in the art of the present invention that various replacements, deformations, and changes may be made without departing from the scope of the invention.
