Description

  The present invention relates to a means for preventing turning of a notch portion when a notch portion is provided in order to fasten a part directly to a floor panel on a floor carpet arranged on the floor of a vehicle. Further, the present invention relates to a turn-up preventing piece formed in a notch portion.

  On the floor of the vehicle, a floor carpet is arranged on the surface of the floor panel to improve the comfort. However, there are members in the vehicle that are directly fastened to the floor panel, such as a bracket for fixing the seat. Therefore, the floor carpet is placed while avoiding these members.

  For this purpose, it is necessary to cut a part of the floor carpet and make a hole. However, forming a hole only in a portion that is directly fastened to the floor panel is troublesome and leads to an increase in cost. Therefore, a cut is made in the floor carpet, and members are arranged through the cut.

  Further, when a member is fastened to the floor panel before placing the floor carpet, it is necessary to place a notch from the edge of the floor carpet and place the floor carpet while avoiding the portion fastened to the floor panel.

  As a result of making the cost as low as possible and simplifying the process as described above, there is a problem that the floor carpet is notched and the carpet turns over over time. In order to solve this problem, the following floor carpet turn-up preventing pieces are known.

  Referring to FIG. 4, Patent Document 1 discloses that a cut-and-raised portion 107 is formed by cutting a floor carpet 105 laid on an upper surface of a vehicle floor panel so that a part of the floor carpet 105 is turned up. In an automobile floor carpet 105 in which an automobile part is attached to a floor panel by turning the portion 107, a groove 106 is formed along the edge of the cut portion of the cut and raised portion 107, and the groove 106 is An automobile floor carpet 105 having a kerf 108 formed therein is disclosed. Reference numeral 109 denotes a notch.

  According to Patent Document 1, it is said that by forming the concave stripe 106 and the like in this manner, the surface rigidity of the floor carpet 105 is improved and the cut-up portion 107 can be prevented from being turned up.

  Further, referring to FIG. 5, a method is known in which a turn-up prevention member 202 for preventing turn-up is attached to the floor carpet 201 and fixed to a garnish 203 such as a vehicle body or a deck side to prevent the turn-up of the floor carpet 201. ing.

  Referring to FIG. 6, a floor carpet 301 having an opening 302 and a slit 303 is attached to the vehicle body, the slit 303 is opened, an in-vehicle member is installed so as to exit from the opening 302, the slit 303 is closed again, and the floor A method for preventing the floor carpet 301 from being turned over by pressing the end of the carpet 301 and a part of the slit 303 with a garnish 304 is also known.

Japanese Patent No. 3296054

  However, in the invention disclosed in Patent Document 1, a groove 106 is formed along the edge of the cut portion of the cut-and-raised portion 107 on the floor carpet 105 of the automobile, and the groove 108 is formed along the groove 106. Since they are formed, there is a problem that the shape is complicated, the appearance is deteriorated, and processing accuracy is required.

  Also in the case shown in FIG. 5, the flip-up preventing member 202 for preventing the turn-up is necessary, and there is a problem that the number of manufacturing steps and the member cost increase as in the invention of Patent Document 1.

  Further, according to the case shown in FIG. 6, the end of the floor carpet 301 and a part of the slit 303 are pressed by the garnish 304 to prevent the floor carpet 301 from being turned up. Therefore, only before the garnish 304 is installed. Since the floor carpet 301 cannot be attached to the vehicle body, the order of attaching the floor carpet 301 to the automobile is restricted.

  In addition, the floor carpet is not bonded to the floor panel because it is required that the floor carpet can be easily removed when the car is dismantled. That is, it is necessary to be able to prevent turning without bonding to the floor panel.

  Therefore, the present invention does not require complicated processing on the floor carpet, can reduce the number of manufacturing steps and member costs, is not restricted in the order of attachment to automobiles, and can be easily removed during disassembly. An object is to provide a carpet anti-turn piece.

In order to solve the problem, the turn-up prevention piece of the floor carpet of the present invention is a turn-up prevention piece of the floor carpet that is fixed to the floor carpet and formed by cutting out from the floor carpet,
A first cut cut in the floor carpet;
A second notch cut substantially perpendicularly from one end of the first notch;
A portion that is separated from the one end by a predetermined length along the first incision and is substantially parallel to the second incision, and is left uncut from the half of the incision length on the first incision side. A third incision having:
A tongue formed by a fourth cut that cuts both the second cut and the third cut at a position farther than twice the length from the first cut to the uncut portion;
It is twisted to a point-symmetrical position with the uncut portion as the center of symmetry,
The tongue piece and the floor carpet overlap with each other, and the portion not cut away from the first cut is fixed to the back surface of the floor carpet.

  According to the turning prevention piece of the present invention, the floor carpet can be prevented from turning without complicated processing. Also, instead of fixing the separated piece from the back of the floor carpet completely, the anti-flipping piece is formed with the connecting part left on the original floor carpet, so no dedicated member is required Thus, waste materials are not scattered during manufacturing, and environmental pollution can be reduced. In addition, since the anti-flipping pieces are formed at the notched portions, the accuracy of forming the portions for preventing the curling is improved.

  From the above, if the turning prevention piece of the present invention is used, the number of manufacturing steps can be reduced, and the member cost, the disposal cost of waste materials, and the like can be reduced, which is effective in reducing the manufacturing cost.

(Embodiment 1)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, FIG. 1A shows a case where the L-shaped bracket 50 is fixed to the floor panel after the floor carpet 1 is laid on the floor panel. First, the floor carpet 1 is disposed on a floor panel. In order to fix the L-shaped bracket 50 for seat installation to the floor panel, it is necessary to make a hole in the floor carpet 1. From the viewpoint of in-car design, it is desirable to make this hole as equal to the cross-sectional area of the L-shaped bracket 50 as possible so that the floor panel cannot be directly seen.

  However, since a certain amount of space is required for fastening the L-shaped bracket 50, an L-shaped cut is made in the floor carpet 1, and an installation space is secured by turning the end. Thereafter, the floor carpet 1 is cut out so that a hole is formed so that the upright wall portion 50a of the L-shaped bracket 50 protrudes. FIG. 1 is a diagram showing a result of fastening the L-shaped bracket 50 in this manner.

  Here, the end 2 of the floor carpet from which the hole 8 of the floor carpet 1 has been cut is formed by cutting the two sides forming the end, so that there is a risk of turning over with time.

  FIG. 1B shows the case of the floor carpet 1 on which the turn-up preventing piece 10 of the present invention is formed. The turn-up preventing piece 10 of the present invention is formed of carpet fabric of the hole 8 cut out to bring out the standing wall 50a of the L-shaped bracket 50, and is fixed to the end 2 of the floor carpet from which the hole 8 has been cut off. Place the tongue piece 3 under the floor carpet fabric beyond the cut. For this reason, the floor carpet fabric disposed below the tongue piece 3 presses the tongue piece 3, so that the end 2 of the carpet from which the hole portion 8 is cut is not turned over.

  Next, with reference to FIG. 2, a method of forming the turn-up preventing piece 10 of the present invention on the floor carpet 1 will be described. A first cut 11 is made in the floor carpet 1 in the vicinity of a place where the member is to be fixed. Next, the second cut 12 is made in a substantially perpendicular direction from one end portion 11a of the first cut 11. That is, an L-shaped cut is made in the floor carpet 1 at this time. The side where the second cut 12 is made when viewed from the first cut 11 is referred to as the tongue piece forming side 20, and the opposite side is referred to as the tongue piece arranging side 21.

  Next, a third cut 13 is made from a portion 11b that is a predetermined distance away from the one end 11a along the first cut 11. The third cut 13 is substantially parallel to the second cut 12 and is cut by the same length as the second cut 12. The third cut 13 is provided with an uncut portion 13a in the middle of the cut. This uncut portion 13 a is provided on the first cut 11 side from half of the entire length of the third cut 13.

  And the 4th cut 14 which cuts both the 2nd cut 12 and the 3rd cut 13 in the position 13b far from twice the length from the 1st cut 11 to the said uncut part 13a is made. In other words, the fourth cut 14 is made at a position away from the first cut 11 so that the uncut portion 13a is closer to the first cut 11 than half of the entire length of the third cut 13. That is. The fourth cut 14 is easy to be formed substantially parallel to the first cut 11, but may not be particularly parallel.

  Through the above operation, the floor carpet 1 has an L-shaped opening formed by the first cut 11 and the second cut 12, and the floor panel can be exposed by turning the end portion 3a.

  Moreover, the tongue piece 3 formed by the 1st thru | or 4th cut and connected to the floor carpet 1 by the uncut part 13a is formed. Next, the tongue piece 3 is twisted to a point-symmetrical position with the uncut portion 13a as the center of symmetry. Specifically, as an example, a method of twisting to a point-symmetrical position by performing line-symmetric bending twice will be shown.

  FIG. 2 (b) shows the first bend. The tongue piece 3 is bent 180 degrees with the uncut portion 13a as one end of a line symmetry axis. More specifically, the fourth notch 14 side of the tongue piece 3 is rotated from the back side of the floor carpet 1, and is rotated beyond the first notch 11 to the back surface of the floor carpet 1 on the tongue piece arrangement side 21. Therefore, the back surface of the floor carpet 1 can be seen from a part 3T of the tongue piece 3 that can be seen in the hole 8.

  Referring to FIG. 2 (c), the tongue piece 3 is then folded in a direction perpendicular to the first folding direction. Therefore, at this time, the uncut portion 13a becomes a part of the middle of the symmetry axis.

  By this two-folding, the tongue piece 3 is twisted to a point-symmetrical position with the uncut portion 13a as a symmetric point. As a result, a hole 8 is formed at the position where the tongue piece 3 was present. Further, when viewed from the tongue piece arrangement side 21, the upper surface of the tongue piece 3 is the surface of the original floor carpet 1.

  Finally, a portion (referred to as “overlapping portion”) 5 where the floor carpet 1 on the tongue piece forming side 20 and the upper surface of the tongue piece 3 overlap is fixed by means such as adhesive or welding. With the tongue piece 3 formed as described above, a part of the tongue piece forming side 20 is protruded, and the turn-up preventing piece 10 fixed to the back surface of the floor carpet on the tongue piece forming side 20 with the overlapping portion 5 is completed. To do. If the anti-flipping piece 10 is arranged on the back surface of the floor carpet 1 on the tongue piece arrangement side 21 and the floor carpet 1 on the tongue piece arrangement side 21 is placed on the anti-flipping piece 10, it exists on the tongue piece forming side 20. The end 2 of the floor carpet from which the hole 8 has been cut is fixed, and the curl prevention piece 10 is not turned over by being pressed by the floor carpet 1 on the tongue piece arrangement side 21.

  Moreover, since the tongue piece arrangement | positioning side 21 and the turn-up prevention piece 10 of the floor carpet 1 and the tongue piece arrangement | positioning side 21 and the tongue piece formation side 20 are not adhering, it can be turned easily when disassembling.

  The turn-up preventing piece 10 of the present invention can be adjusted in size and length at the positions of the first to fourth cuts in the floor carpet 1 and the uncut portion 13 a provided in the third cut 13. . That is, the width and length of the turn-up preventing piece 10 can be easily set. For example, the width 10 a of the turn-up preventing piece 10 can be determined by the widths of the second cut 12 and the third cut 13. Further, the length 10b of the turn-up preventing piece 10 can be determined by the lengths of the second and third cuts (12 and 13) and the position of the uncut portion 13a.

  Since the curl prevention piece 10 must be formed by protruding from the tongue piece forming side 20 to the tongue piece arrangement side 21, at least the uncut portion 13 a is the first cut from half the length of the third cut 13. Must be set to 11 side.

  The uncut portion 13a is formed by cutting out the floor carpet 1 so that the tongue piece 3 can be twisted and has a strength that does not break. Specifically, the length of the uncut portion 13a is preferably 1 to 2 mm.

  The first cut 11 may be from any position on the floor carpet 1, for example, from one of the edges of the floor carpet 1. Of course, you may give to the part which is not the edge of the floor carpet 1. FIG. The first to fourth cuts are preferably straight lines, but curves other than straight lines may be used.

However, in the present embodiment, the first cut is replaced with one of the edges (1a) of the floor carpet 1. That is, the second to fourth cuts (12 to 14) are made on the floor carpet 1 from one edge 1a, but the turn-up preventing piece 10W can be formed on the tongue piece arrangement side 21E as in the first embodiment. . In the present embodiment, since the first cut is replaced with the edge 1a of the floor carpet 1, the tongue piece arrangement side 21E is outside the floor carpet 1.

  In the case of the present embodiment, the turn-up preventing piece 10 </ b> W can be formed to protrude from the edge 1 a of the floor carpet 1. Therefore, when placing a member on the edge of the floor carpet 1 at a location close to the garnish or the like, by forming the turn-up preventing piece 10W of the present embodiment on the edge and pressing the turn-up preventing piece 10W with the garnish, The floor carpet 1 can be fixed.

  Further, since the curl prevention piece 10W of the present invention rotates the tongue piece 3 cut out from the floor carpet 1 twice, the upper surface 10c of the curl prevention piece 10W protruding to the tongue piece placement side 21E is the floor carpet. Because it is an upper surface (textured surface), it looks good.

(Embodiment 3)
FIG. 3B shows a turn-up preventing piece 10V of the present embodiment. In the present embodiment, in addition to the first cut, the second cut is replaced with the edge 1b of the floor carpet. That is, the third and fourth cuts (13 and 14) are only made on the floor carpet 1. In the present embodiment, since the hole 8 (notch) is formed in the corner portion of the floor carpet 1, a member is disposed at the corner of the floor panel, and the floor carpet 1 is preferably used to avoid it. Available.

  In addition, including Embodiment 2, the tongue piece 3 formed by cutting the floor carpet 1 may not be used as it is. More specifically, the formed tongue piece 3 may be cut into a desired size or shape and used.
