Description

  The present invention relates to a floor mat laid on a floor surface of a vehicle interior of a vehicle, for example, and more particularly to a floor mat having hook-and-loop-like locking means formed on the back surface.

  As a mat having a hook-and-loop locking means on the back surface, for example, there is one disclosed in Patent Document 1 below.

  In this mat, a raschel knitted fabric having a loop pile made of monofilament yarn is bonded to the back surface of the mat, and a spherical molten mass is formed at the tip of the loop pile of the raschel knitted fabric. At the time of heating to form the spherical molten mass, the loop pile is pressed to be tilted apart, and the posture of the loop pile is heat-set in this state.

  That is, when it is placed on the rug laid on the floor of the automobile, the loop piles that are inclined to the rug are locked to the pile of the rug, and the laying position is fixed.

  A similar one is disclosed in Patent Document 2 below. This mat is devised to disperse the direction of the pile, and the warp yarn of the raschel knitted fabric forms a loop pile with the chain yarn and the fixed course, and the chain is between the fixed courses. The pile yarn is composed of knitted pile yarn, and the pile yarn is composed of two or more monofilaments, and is twisted one or more times in the length of the loop pile. That is, when the loop pile is cut in the vicinity of the top to form a cut pile by the number and twist of the above-mentioned monofilaments, two or more monofilaments are inclined and stand up.

Japanese Patent Publication No. 3-60483 Japanese Patent No. 4074657

  According to the structure of patent document 2, there exists an advantage which can abbreviate | omit the heat set which inclines a pile apart. However, the Russell knitted fabric having the configuration of Patent Document 2 cannot be manufactured by a general Russell knitting machine, and costs are high.

  In addition, since the locking means is locked to the pile napping of the rug, it is desirable to change the locking force according to the laying location in order to secure the detachment workability while firmly fixing the position. That is, if the locking force is increased at the laying site where the force is easily applied and the locking force is decreased at the laying site that is not so, an effective fixed state in which the locking force is not excessive or insufficient can be obtained.

  However, since the locking means is composed of a knitted fabric, it is necessary to manufacture another woven fabric with different meshes in order to change the density of the pile.

  There are various types of floor mats, and it is not necessary that all portions of the floor mat have the same locking force. However, the pile density cannot be changed for each part according to the shape of the floor mat.

  Further, since the insertion yarn which is the weft for joining the warp yarns two-dimensionally is provided, the portion of the insertion yarn may be lifted by repeated attachment and detachment of the floor mat, which may lead to the peeling of the raschel knitted fabric.

  In view of this, the main object of the present invention is to enable low-cost production.

  The means for this is a floor mat in which the locking means for locking to the laying surface is formed on the back surface, and the locking means is configured by disposing a linear body having linear protrusions. Floor mat.

  In this floor mat, the linear protrusion of the linear body is locked by being pierced with respect to the laying surface, and the laying position of the floor mat is fixed. Unlike the case of the knitted fabric, the direction of the linear protrusions of the linear body is not fixed, or even if it is fixed, it is easy to change the direction at the time of fixing.

  As described above, according to the present invention, the locking means is constituted by a linear body having linear protrusions, not a special raschel knitted fabric, so that special knitting and processing are unnecessary, and it is inexpensive. Can be manufactured.

  An embodiment for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a plan view showing the back surface of a floor mat 11 for an automobile, and FIG. 2 is an enlarged perspective view showing a part of FIG.

  As shown in these drawings, on the back surface of the floor mat 11, a locking means 12 that locks against a rug (not shown) as a laying surface that is laid on the floor surface in the interior of the automobile. Is formed. And this latching means 12 is comprised by arrange | positioning the linear body 21 which has the linear protrusion 21a. As shown in FIG. 2, the protrusion 21 a faces in a disjoint direction, and pierces and locks against the pile of the rug.

  The protrusion 21a is made of a synthetic resin monofilament having elasticity and rigidity. The tip 21a is rounded by heat treatment so that it does not hurt by being stuck in a hand or the like during handling, and a spherical portion 21b is formed.

  As shown in FIG. 2, the linear body 21 is fixed so as to be exposed on one surface of the nonwoven fabric 13 as a base material, and the opposite surface of the nonwoven fabric 13 is fixed to the back surface of the mat body 14.

  The linear body 21 may be fixed to the non-woven fabric 13 by a method of fixing with a needle punch (see FIG. 3), a method of sewing by directly sewing the linear body 21 (see FIG. 4), or the like. Further, in order to fix the nonwoven fabric 13 to the mat body 14, an appropriate means such as a hot melt adhesive is used, and piping, thermocompression bonding, etc. are appropriately applied to the outer peripheral edge (see FIG. 1) as necessary. Is done.

  The linear body 21 has a large number of linear protrusions 21a extending in a direction intersecting the length direction of the linear body 21, and is configured as illustrated in FIGS.

  The linear body 21 shown in FIG. 5 is formed by cutting a double raschel knitted fabric made of synthetic resin monofilament into a thin linear shape or a double raschel string 25 (see FIG. 5A) by center cutting. It is formed by dividing (see FIG. 5B). In the figure, 25a is a front side chain knitting portion, 25b is a back side chain knitting portion, and 25c is a crossover yarn that three-dimensionally connects the front side chain knitting portion 25a and the back side chain knitting portion 25b. The thread becomes the protrusion 21a. The linear body 21 has a large number of protrusions on one side in the length direction. In FIG. 5, a two-dot chain line is a line indicating a cut position. The same applies to FIGS.

  In order to prevent the monofilaments constituting the double raschel knitted fabric or the double raschel string from being scattered by the center cut, heat treatment is preferably performed before the center cut to keep the joints of the monofilament knots. Therefore, the monofilament is heat-treated using a meltable one, a core-sheath two-layer structure having a sheath to be melted, or a heat welding yarn (not shown).

  The linear body 21 shown in FIG. 6 is formed by cutting a monofilament plain woven fabric 26 (see FIG. 6A) made of synthetic resin in the length direction (see FIG. 6B).

  In the woven fabric 26, a gap 26c is formed between the warp groups 26b composed of a plurality of warp yarns 26a so as to obtain protrusions having a desired length. When cut between the warp groups 26b, FIG. A plurality of linear bodies 21 as shown in b) are obtained. This linear body has a large number of protrusions 21a on both sides in the length direction.

  Also in this case, it is preferable to keep the connection of the knots of the monofilament by heat treatment before the cut so that the monofilament does not come apart. For this reason, the monofilament is heat-treated using a meltable one, a core-sheath two-layer structure having a sheath to be melted, or a heat welding yarn.

  The linear body 21 shown in FIG. 7 is formed by cutting a woven fabric 27 (see FIG. 7A) of a monofilament made of synthetic resin in the length direction (see FIG. 7B). Although different from the case of FIG. 6 in the way of weaving the warp yarn 27a, the other parts are the same as in the case shown in FIG. 6, so the same reference numerals are assigned to the same parts as shown in FIG. Detailed description will be omitted.

  The linear body 21 shown in FIG. 8 is configured as a molding thread using a monofilament made of synthetic resin. As is well known, the Mole yarn has a structure that can be obtained by twisting two yarns (core yarn and presser yarn) and winding another yarn (flower yarn) and cutting the wound yarn. In the example shown in the drawing, it is drawn on a plane for convenience (see FIGS. 8A and 8B), but the flower yarn that becomes the protrusion 21a spreads in all directions.

  In this case as well, it is preferable to keep the joints of the knots of the monofilament by heat treatment before the cut so that the monofilament does not come apart. For this reason, the monofilament is heat-treated using a meltable one, a core-sheath two-layer structure having a sheath to be melted, or a heat welding yarn.

  In addition, when the number of flower yarns that become protrusions is too large, as shown in FIG. 8B, it is preferable to cut other flower yarns 21c short so that some flower yarns become protrusions. The shortly cut flower yarn 21c is stabbed or entangled when fixed to the nonwoven fabric 13, and exhibits an anchor effect for the nonwoven fabric 13.

Next, a method for manufacturing the floor mat 11 using such a linear body will be described.
First, the linear body 21 is fixed to the nonwoven fabric 13 so as to be exposed on one side of the nonwoven fabric 13. This fixing can be performed by needle punching or sewing as described above, but when fixing, a plurality of linear bodies 21 are prepared and arranged in parallel. For example, as shown in FIG. 9, the linear body 21 is lowered with respect to the nonwoven fabric 13 conveyed sequentially, it presses with the roller 31, and needle punching is performed.

  At this time, the spacing between the linear bodies 21 depends on the locking force required by the floor mat 11 (where the floor mat 11 is laid and which part of the floor mat 11) and the linear body 21. It is set as appropriate depending on the stopping ability.

  As shown in FIG. 10, a portion having a narrow interval and a wide portion are partially provided to form a high density portion 12a having a narrow interval and a low density portion 12b having a wider interval and a low density and locking force. You can also It is preferable to form a high-density portion in a portion where a load in the misalignment direction is easily applied during use or a portion that requires a strong locking force in terms of shape.

  Moreover, as shown in FIG. 11, not all the linear bodies 21 to be placed are fixed straight, but are partially or wholly bent and fixed to form the high density portion 12a and the low density portion 12b. You can also.

  As shown in FIG. 12, the locking means 12 can be formed by fixing one linear body 21 in a zigzag manner.

  In addition, in the front | former stage in which the linear body 21 is supplied to the nonwoven fabric 13, it is the state by which the linear body 21 was wound up, and since it is linear, the directionality of the processus | protrusion 21a is also different. For this reason, the protrusion 21a is directed in all directions even if it is unwound from the wound-up state and mounted or sewn as it is, and the state as shown in FIG. 2 is obtained. However, for example, as shown in FIGS. 6 and 7, when the direction of the protrusion 21 a is in a certain direction, there is a possibility that the directionality is likely to be fixed even if the protrusion 21 a is wound. There is. In such a case, it is good to fix to the nonwoven fabric 13 while moving the linear body 21 so that it may become a different attitude | position from the part fixed previously.

  For this purpose, for example, as shown in FIG. 13, the beam 32 that is winding the linear body 21 may be hanged so as to be rotated and slowly rotated by the rotational force from the motor 33. Since the linear body 21 is supplied to the nonwoven fabric 13 while rotating, the direction of the protrusions 21a of the linear body 21 changes sequentially, and the protrusions 21a facing in all directions are obtained.

  Further, as shown in FIG. 14, a large number of irregularly shaped protrusions 31 a may be provided on the outer peripheral surface of the roller that presses the linear body 21 against the nonwoven fabric 13. When the roller 31 rotates and a large number of protrusions 31a press the linear body 21 one after another, the direction of the protrusions 21a of the linear body 21 is changed depending on the presence or absence of the protrusions 31a and the form thereof.

  After supplying the linear body 21 as described above, the linear body 21 is fixed to the nonwoven fabric 13 by an appropriate method such as needle punching as described above.

  Then, the non-woven fabric 13 to which the linear body 21 is fixed is bonded to the back surface of the separately manufactured mat body 14, and if necessary, such as piping, the floor mat 11 is completed.

  The floor mat 11 completed in this way can be fixed without displacement only by being placed on the floor covering in the passenger compartment. That is, the projection 21a of the linear body 21 constituting the locking means 12 on the back surface of the floor mat 11 is stuck into the pile of the rug and locked, and the laying state is fixed.

  Moreover, as described above, if the high density portion 12a and the low density portion 12b are formed in accordance with the form and the fixing location of the floor mat 11, there is no excess or deficiency that ensures both a secure fixed state and easy attachment / detachment. Effective fixing can be performed. In particular, when the linear bodies 21 are arranged side by side, it is easy to provide the density.

  Moreover, since the linear body 21 is used for the locking means 12, it can be manufactured at a lower cost than when a special knitted fabric as in the prior art is used, and the direction of the protrusion 21a of the linear body 21 is Even if it is not disjoint, it is easy to fix the protrusions 21a of the linear body 21 in disjoint directions.

The above is one form for implementing this invention, This invention is not limited only to the above-mentioned structure, Other forms can also be employ | adopted.
For example, the base material to which the linear body is fixed may be other than the nonwoven fabric.
