The present invention, which has been researched and developed in order to achieve the above object, is provided with a rack which slides up and down in the center of a cylindrical hook installed on a floor carpet above the vehicle floor panel so as to penetrate and fix one side of a car mat of the vehicle. An arc-type pinion is installed to be engaged with the rack on one side, and both ends of the pinion are carmat fixing devices, characterized in that fixing means provided with an elastic member is installed on one side of the cylindrical body.

Hereinafter, the technical features of the present invention will be described in more detail with reference to the accompanying drawings.

Figure 2 is a cross-sectional view before the mat is fitted to the mat mat fixing device according to the present invention, Figure 3 is a cross-sectional view showing a state in which the mat is fitted to the mat mat fixing device of the present invention, Figure 4 is It is sectional drawing which shows the state which remove | eliminates a carpet in a carpet fixing device.

According to a known technique, a floor carpet is installed on the floor panel of an automobile, and a carpet for cleaning and protecting the floor carpet from contaminants is superimposed on the floor carpet, which is usually a hook installed on the floor carpet. Is inserted into a through hole formed at one side of the mat, and the mat is fixed.

However, the carmat fixing device of the present invention provides a rack 20 which slides up and down in the hook body 10, and installs a pinion 30 engaged with one side of the rack 20, and the pinion ( Fixing means 40 and 50 are provided at both ends of 30 to prevent the carpet 3 from being unnecessarily separated from the hook 10.

First, the rack 20 is installed in a direction perpendicular to the floor carpet 2 in the inner center of the cylindrical hook body 10, and should slide up and down, wherein the upper portion 21 of the rack 20 is hook body ( 10 so as to be protruded outward, the teeth 23 are formed in the lower portion 22 of the rack 20 by a predetermined length. Thus, at least one side of the teeth 23 formed in the lower portion 22 of the rack 20 is provided with an arc-shaped pinion 30 meshing with the rack 20, the pinion 30 is the extension portion 31 in the center Is formed and is pivotally coupled to the end of the extension 31. In addition, both ends of the pinion (30) are provided with fixing means (40, 50) equipped with elastic members (41, 51) on one side of the cylindrical hook body (10), which is installed on the upper end of the pinion (30) for convenience. The fixing means is called the first fixing means 40, and the fixing means installed at the lower end is called the second fixing means 50, and the elastic member which is installed in the first fixing means 40 is first elastic member ( 41) or the elastic member installed in the first spring 41 and the second fixing means 50 is referred to as the second elastic member 51 or the second spring (51). The first fixing means 40 and the second fixing means 50 are formed with slit grooves 42 and 52 at the front end thereof coupled with both ends of the pinion 30, and at the rear ends of the slip grooves 42 and 52. Rods 43 and 53 having elastic members 41 and 51 are formed so that the rods 43 and 53 protrude out of the hook body 10 depending on the operating state. Here, the reason that the slip grooves 42 and 52 are formed at the front end where the pinion 30 and the fixing means 40 and 50 are coupled to each other is that the fixing means 40 and 50 are linearly moved horizontally. Since the pinion 30 is rotated through the pin 32 in the center, the slip grooves 42 and 52 having a predetermined clearance are provided to transmit the rotational force of the pinion 30 to the fixing means 40 and 50. It is natural to be prepared. In addition, a push button 54 for providing a pressing force into the hook body 10 is installed at the outermost portion of the rod 53 of the second fixing means 50 installed at the bottom of the pinion 30. 54 is an appropriate inclination angle so that the push button 54 is pushed into the hook body 10 while the mat 3 is fitted to the hook body 10 from the upper side to the lower side. It must be formed.

On the other hand, the spring constant of the first elastic member 41 that is installed in the first fixing means 40 is greater than the spring constant of the second elastic member 51 that is installed in the second fixing means 50, The first fixing means 40 provides the thrust to the pinion 30, and again the pinion 30 transmits a force to the second fixing means 50 to load the rod in a state in which the second elastic member 51 is compressed. 53) The outermost push button 54 is protruded out of the hook body (10).

Of course, there is no problem in fixing the mat 3 with only the above configuration, More preferably, the arc-type pinion 30 and the plurality of fixing means 40, 50 are symmetrical with respect to the rack 20. Another tooth 23a is formed on both lower end surfaces of the rack 20 installed in a single vertical direction, and separate arc-type pinions 30a are fitted to the pins 30a. It is preferable that the same fixing means 40a and 50a are installed. In addition, a cap 11 having a hook ring 11a formed on one side is installed at the upper portion of the hook body 10 to protect the protruding rack 20 and to prevent unnecessary stepping on the foot.

The operation of the present invention by the above configuration is as follows, and since the symmetrical parts have the same operation in the same configuration, one code is used.

As shown in FIG. 2, since the spring coefficient of the first elastic member 41 is greater than the spring coefficient of the second elastic member 51, the first fixing means 40 uses the second fixing means via the pinion 30. The thrust is provided to the 50 so that the push button 54 formed at the outermost portion of the second fixing means 50 is protruded out of the body 10. At this time, the through hole of the mat 3 is inserted into the hook body 10, and the metal part 3a formed on the inner circumferential surface of the through hole presses the push button 54 of the second fixing means 50, and the second fixing means ( 50 overcomes the thrust provided from the first fixing means 40 and the force is transmitted to the first fixing means 40 again via the pinion 30 as shown in FIG. The rod mat 43 is projected out of the hook body 10, so that the mat 3 is caught, so that the mat 3 is not caught by the rod 43 of the first fixing means 40. Here, the force provided from the second fixing means 50 is compressed and stored in the first elastic member 41. On the other hand, when the arc-shaped pinion 30 is rotated about the pin 32 formed in the central extension portion 31, the force is also transmitted to the rack 20 having a vertical movement path engaged with the rack. 20 slides up. Therefore, the upper portion 21 of the rack 20 is to protrude to the upper end of the hook body (10). In addition, even if the upper portion 21 of the rack 20 protrudes out of the hook body 10, the cap 11 is installed on the upper portion of the hook body 10 to protect the upper portion 21 of the protruding rack 20. You can avoid stepping on by mistake.

However, when it is necessary to remove the mat 3 due to the dirt of the mat 3 mounted on the floor, as shown in FIG. 4, the cap 11 formed on the hook body 10 is opened and the rack ( When the upper portion 21 of the 20 is pressed by hand, the rack 20 is slid down to rotate the arced pinion 30, which has been engaged, in the downward direction, whereby the rod of the first fixing means 40 in which the compressive force is stored. 43 is inserted into the hook body 10. However, the second fixing means 50 which is to protrude out of the hook body 10 by the rotation of the pinion 30 does not protrude because of the mat 3 which is not removed yet. The force received from 30 is stored. That is, both the first fixing means 40 and the second fixing means 50 are located inside the hook body 10. In this state, the carpet 3 may be removed from the hook body 10 by hand, and the state of the hook 10 after the removal is the same as in FIG. 2.

As described above, according to the cart fixing device according to the present invention, the car carpet is reliably fixed to the floor carpet laid on the floor panel, thereby preventing the carpet from being pushed.
