Description:
FIELD OF THE INVENTION 
     The present invention relates to clip for fixing a mat of carpet of a vehicle, and more particularly, to a clip that can be doubly fixed to the carpet, while quickly and easily mounting the clip to the carpet, by forming two fasteners assembled to the clip in a one-touch manner, and strengthens the coupling force of the clip to prevent the clip from being detached from the carpet. 
     BACKGROUND 
     In general, when mats are used by being additionally mounted on carpets in a vehicle, clips for fixing the mats are fixedly installed on the carpet, and the mats are fixed by being hooked to the clips. Patent Documents 1 and 2 disclose configurations of clips used to fix mats on carpets in this way. 
     Patent Document 1 relates to a clip for fixing a mat on a carpet of a vehicle, and discloses the clip that includes a lower plate that is located on a lower surface of the carpet and has insertion grooves formed in a front section; an upper plate that is located on an upper surface of the carpet and has hooks to be fastened to the insertion grooves formed in a front section thereof and a protrusion to which the mat is fitted formed in a upper part thereof; a column that passes through a hole of the carpet and vertically connects a rear section of the lower plate and a rear section of the upper plate; and a pressing unit that is formed by a flexible material to enhance a fixing force of the clip to the carpet by pressing the carpet section fitted between the upper plate and the lower plate upward when the upper plate and the lower plate are fastened, has an annular longitudinal sectional surface, and by which the upper part and the lower part gradually come closer to each other when the upper plate and the lower plate are fastened. 
     Patent Document 2 relates to a vehicle carpet reinforcing structure which reinforces a vehicle carpet to be fixed with a mat using a fixing clip, and a method of manufacturing the same. The vehicle carpet reinforcing structure includes a body that is located to correspond to a lower part of the fixing clip and has a plate shape body; and a fixing unit installed on one side of the body to fix the body to the carpet. According to the vehicle carpet reinforcing structure and method of manufacturing the same of Patent Document 2, by reinforcing the carpet to correspond to a bottom surface of the fixing clip for fixing the mat, it is possible to suppress the damage or deformation of the carpet due to the movement of the fixing clip and to extend the lifetime of the carpet. 
     However, such conventional clips have the following problems: 
     (1) Since the upper plate and the lower plate are formed to be divided, it was inconvenient to mount the clip to the carpet. 
     (2) Since the clip is fixed to the carpet in the form of an elastic piece, when a weak impact is applied to the clip, the elastic piece is easily unfixed, and the clip may be detached from the carpet; 
     (3) The mat fixed to the clip deviates from its original position due to the detachment of the clip, and there is an inconvenience in that the mat is required to be fixed at its original position again or repositioned; 
     (4) When the clip is frequently unhooked or does not work due to damage or the like, since there is a need to replace the clip with a new one, there is an inconvenience in maintenance; 
     (5) In particular, since the fixing unit of the clip made in the form of the elastic piece loses elasticity over time, ultimately, the clip may be detached from the carpet; and 
     (6) Since the elastic piece has a form in which it is hooked on only one side, when loads are applied to the clip from several directions, the clip is easily unhooked, and the clip may be detached from the carpet.

     Patent Document 2 Korean Patent No. 10-1210463 (registration date: Dec. 4, 2012) 
     SUMMARY OF THE INVENTION 
     The present invention is directed to provide a mat fixing clip of a vehicle carpet that is configured to fix the clip to the carpet by one fastener and then to fix the fixed fastener in advance while covering the fastener by another fastener, and doubly couples and fixes the clips to the carpet using these fasteners, thereby easily and quickly mounting the clip to the carpet to improve assemblability, and fixes the clip twice to prevent the once mounted clip from being detached from the carpet and improve the coupling force. 
     In particular, the present invention is directed to provide a mat fixing clip of a vehicle carpet that enables the two fasteners to fix the carpet in opposite directions, thereby being able to complement the coupling strength at the coupling site and further enhance the coupling strength. 
     Moreover, the present invention is directed to provide a mat fixing clip of a vehicle carpet that allows the two fasteners to be mounted on the carpet in a one-touch manner, thereby easily and quickly mounting the clip, and allows the clip to be easily detached when it is needed to remove the clip. 
     One aspect of the present invention provides a mat fixing clip of a vehicle carpet which includes a body  100  which has a hook  110  formed on one side of the body to hook a mat M a first fastener  200  that is formed in two mounting holes H 1  and H 2  formed in a carpet C to fix the carpet C, a second fastener  300  that is formed between the mounting holes H 1  and H 2  in a form which covers the first fastener  200  to fix the carpet C, and a plurality of pressing protrusions  120  formed to contact the carpet C, wherein each of the first fastener  200  and the second fastener  300  comprises supports  210  and  310  formed at the body  100  to protrude outward through any one mounting hole; hooking jaws  220  and  320  formed in the body  100  to protrude outward through the other mounting hole; and pressing plates  230  and  330  that are rotatably formed in the supports  210  and  310  and are hooked at front ends by the hooking jaws  220  and  320  to press the carpet C. 
     In particular, the pressing plate  230  may further have an elastic deformation protrusion  234  on a surface that faces the carpet C. 
     In addition, the respective pressing plates  230  and  330  may be formed to be rotatable by being connected to the supports  210  and  310  by weakened sections  231  and  331 . Each of the pressing plate  230  and  330  may be installed on the supports  210  and  310  to rotate in opposite directions to each other. 
     The pressing plate  230  and  330  may be installed to contact each other and hooking protrusions  232  and  332  may be formed in the surfaces contacting each other to be fixed by being hooked to each other. 
     Finally, insertion grooves  233  and  333  may be formed at tips of the pressing plate  230  and  330  to be coupled to the hooking jaws  220  and  320  in a one-touch manner. 
     According to the mat fixing clip of the vehicle carpet of present invention, there are following effects. 
     (1) Since the clip is doubly mounted and fixed to the carpet using two fasteners, it is possible to strengthen the binding force of the clip and prevent the clip from being easily detached from the carpet. 
     (2) In particular, by setting the different positions at which the two fasteners are coupled to each other, even if an external force is applied to the clip, there is an effect of dispersing the external force to the two fasteners, and it is possible to enhance the effect of preventing the clip from being detached from the carpet. 
     (3) Since the two fasteners are coupled in a one-touch manner to fix the clip to the carpet, the clip can be easily mounted on the carpet and can be easily detached. 
     (4) By forming the elastic deformation protrusion on the fastener that is in direct contact with the carpet, when fixing the clip to the carpet by the fastener, the elastic deformation protrusions enhances the mounting force of the clip while being deformed between the carpet and the fastener to prevent the detachment of the clip. 
     (5) Since the two fasteners are connected to each other using the hooking jaws to perform the hooking operation on the surface by which the two fasteners contact each other, it is possible to further enhance the coupling force between the clip and the carpet as well as between the fasteners. 
     (6) Since the two fasteners are integrally manufactured, the manufacturing process can be reduced and the mass-production is possible.

     DETAILED DESCRIPTION OF THE INVENTION 
     Hereinafter, exemplary embodiments of the present invention will be described in detail. However, the present invention is not limited to the exemplary embodiments disclosed below, but can be implemented in various forms. The following exemplary embodiments are described in order to enable those of ordinary skill in the art to embody and practice the invention. 
     Therefore, since the exemplary embodiments described herein and the configuration illustrated in drawings are merely the most preferred embodiment of the present invention and are not intended to limit all the technical ideas of the present invention, it should be understood that there may be variations equivalents or modifications capable of replacing them at the time of filing this application. 
     (Configuration) 
     As illustrated in  FIGS. 1 to 4 , a mat fixing clip of a vehicle carpet according to the present invention is configured to include a body  100 . A hook to which the mat M can be hooked is formed on one side of the body, and a first fastener  200  and a second fastener  300  for doubly fixing the carpet C are formed at the other side. 
     In particular, the first fastener  200  and the second fastener  300  are configured to rotate in opposite directions to each other to mount the clip to the carpet C, thereby enhancing the mounting force of the clip and allowing the attachment and detachment in a one-touch manner to easily and quickly perform assembling and disassembling. 
     Hereinafter, each component according to the present invention will be specifically described. Here, the carpet C is produced by being mounted in a vehicle by a conventional technique, and two mounting holes H 1  and H 2  are formed therein to mount the clip used to fit and fix the mat M. Moreover, the mat M mounted on the carpet C is also produced by a conventional technique. 
     As illustrated in  FIGS. 1 and 2 , the body  100  is manufactured in a plate form having a predetermined size, and a hook  110  is formed on one side. The hook  110  is intended to hook and fix the mat M mounted on the carpet C. 
     Further, a plurality of pressing protrusions  120  are formed on the other side of the body  100 . The pressing protrusions  120  are in contact with the carpet C as the body  100  is placed over the carpet C, and are fitted to the carpet C in the form of a wedge as the clip according to the present invention is mounted, and have a function of enhancing the mounting force of the clip. 
     On the side formed with the pressing protrusions  120 , the first fastener  200  and the second fastener  300  are configured. 
     As illustrated in  FIGS. 1 and 2 , the first fastener  200  is configured to include a support  210  and a hooking jaw  220  formed to protrude outward through the two mounting holes H 1  and H 2  formed to mount the clip on the carpet C, and a pressing plate  230  that is formed in the support  210  to be rotatable and is press-fitted to the hooking jaw  220  to press the carpet C. 
       FIG. 2  illustrates a state in which the support  210  protrudes from the right mounting hole H 1  and the hooking jaw  220  protrudes from the other mounting hole H 2 . Moreover, although the support  210  and the hooking jaw  220  may be formed as separate components and mounted to the body  100 , they may be preferably formed integrally with the body  100 . 
     As illustrated in  FIG. 2 , the pressing plate  230  is formed in the support  210  to be rotatable. At this time, the pressing plate  230  may be manufactured separately from the support  210 , or may be manufactured integrally with the support  210 . When it is manufactured integrally with the support  210 , the pressing plate is formed to be easily rotatable toward the hooking jaw  220  around a weakened section formed as the weakened section  231 . 
     Also, an insertion groove  233  is formed at the tip of the pressing plate  230  to have a shape that covers the hooking jaw  220 , and when pressing the insertion groove  233  while contacting the hooking jaw  220 , it can be coupled in a one-touch manner, and thus, the first fastener  200  can be easily mounted. In the drawings, reference numeral “ 233   a”  which is not described is a handle formed on the insertion groove  233 . When pressing the handle, the insertion groove  233  is easily detached from the hooking jaw  220  in a one-touch manner while the insertion groove  233  is deformed. 
     In a preferred embodiment of the present invention, it is preferable to further form an elastic deformation protrusion  234  on a surface of the pressing plate  230  that faces the carpet C. The elastic deformation protrusion  234  causes deformation in the carpet C and the pressing plate  230  as the pressing plate  230  rotates and the insertion groove  233  is fitted to the hooking jaw  220 , thereby elastically supporting the first fastener  200  to be firmly fixed therebetween without play. 
     As illustrated in  FIGS. 1 and 2 , the second fastener  300  is formed by a support  310 , a hooking jaw  320  and a pressing plate  330 . Since such a configuration is substantially the same as the first fastener  200  described above, only the differences are described below, and the detailed description of the similarities will be omitted. In the drawings, in the same configuration, in the case of the second fastener  300 , the first digit of the three-digits is represented by “3”. 
     The support  310  and the hooking jaw  320  are formed in the two mounting holes H 1  and H 2 , similarly to the first fastener  200 . Therefore, there is a risk that the first fastener  200  and the second fastener  300  may overlap. Therefore, by forming the configuration in which the second fastener  300  covers the first fastener  200 , the first fastener  200  and the second fastener  300  are configured so that they do not overlap each other and do not interfere with each other. 
     That is, the distance between the support  210  and the hooking jaw  220  of the first fastener  200  is disposed to be located slightly longer than a minimum distance between the two mounting holes H 1  and H 2 , and the distance between the support  310  and the hooking jaw  320  of the second fastener  300  is formed to be slightly longer than this distance. Thus, the pressing plate  330  of the second fastener  300  is has a form which covers the pressing plate  230  of the first fastener  200 . Therefore, an elastic deformation protrusion  234  is not formed in the pressing plate  330  unlike the first fastener  200 . 
     In a preferred embodiment of the invention, although the pressing plate  330  of the second fastener  300  may be configured to rotate in the same direction as the pressing plate  230  of the first fastener  200 , they are preferably formed to rotate in opposite directions to each other. The reason is that sections formed integrally with the weakened sections  231  and  331  are distributed to both sides, and the coupling method of the one-touch manner using the hooking jaws  220  and  320  are distributed to both sides, and the left and right sides are symmetrical to each other in a double fixing structure, and the load is distributed to minimize the detachment of the clip. 
     Also, in a preferred embodiment of the present invention, as illustrated in  FIGS. 1 and 2 , it is preferred that each of the hooking protrusions  232  and  332  is formed in the pressing plates  230  and  330  to overlap each other, and as the second fastener  300  is mounted after mounting the first fastener  200 , the hooking protrusions  232  and  332  are hooked to each other to enhance the coupling force between the first fastener  200  and the second fastener  300 . 
     (Assembly) 
     As illustrated in  FIGS. 2 to 4 , the clip according to the present invention is assembled to the carpet C, and then, the mat M is covered thereon and the clip is fixed to the hook  110 . The procedure is as follows. 
     First, as illustrated in  FIG. 2 , the clip according to the present invention is fitted to the carpet C so that each of the supports  210  and  310  is fitted to the mounting holes H 1  and H 2 . 
     Next, as illustrated in  FIG. 2 , the pressing plate  230  is rotated in a clockwise direction, and after the insertion groove  233  is fitted to the hooking jaw  220 , it is strongly pushed and press-fitted as illustrated in  FIG. 3 . At this time, the pressing plate  230  presses the carpet C while pressing and deforming the elastic deformation protrusion  234 , and thus, the pressing protrusion  120  is also pressed and is stuck to the carpet C like a wedge. 
     Next, as illustrated in  FIG. 3 , the pressing plate  330  rotates in a counterclockwise direction, the insertion groove  333  is fitted to the hooking jaw  320 , and then, it is forcibly pressed and press-fitted as illustrated in  FIG. 4 . At this time, the locking protrusions  232  and  332  formed between the pressing plates  230  and  330  are hooked to each other, and the assembly of the clip is finished. 
     Finally, as illustrated in  FIG. 4 , the finishing work is performed by hooking the mat M overlying the carpet C to the hook  110 . 
     Meanwhile, when the clip according to the present invention is separated as needed, the clip is detached from the hooking jaws  220  and  320  while the insertion grooves  233  and  333  are deformed by grasping and pulling the handles  233   a  and  333   a  outward, and the hooking operation is released. 
     As described above, according to the present invention, by allowing the clip to have the double locking functions using the two fasteners, it is possible to prevent the clip from being detached from the carpet. Moreover, the two fasteners prevent the clip from being easily detached from the carpet, by allowing the coupling in the opposite directions to each other and by allowing the load applied to the clip to be distributed to both sides. 
     Also, since the present invention allows the two fasteners to be attached and detached in a one-touch manner, it is possible to easily and quickly perform the mounting and disassembling tasks of the clip.
