Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stationary carpet mat to be installed and laid on a carpet.

[0002]

2. Description of the Related Art In order to prevent stains on the surface of a carpet that has been pasted on an automobile floor or a floor such as an entrance, a carpet mat that is easy to remove and clean is placed on this carpet. It is widely used. However, when footwear or the like comes into contact with the laid carpet mat laid on the carpet, the laid carpet mat may shift on the carpet floor surface.
In this way, if the position of the carpet mat is deviated, it becomes unsightly. Furthermore, if the stationary carpet mat laid on the driver's side of the automobile floor is displaced, the stationary carpet mat may cover the accelerator and brake petals, hindering safe driving. It is necessary to prevent movement.

As a method for preventing the displacement, there is a method in which male pieces of Velcro tape are attached to the back surface of the laid carpet mat by sewing with a sewing machine. This floor carpet carpet has brushed floor carpets that look like loop pile or needle punch carpet.
It is very effective in the form with the hooked portion. However, when the raised carpet on the floor surface is not hooked like a cut pile, it is completely ineffective.

Further, in the case of the side of the driver's seat of the above-mentioned automobile, a male metal fitting is installed on the floor and a female metal fitting is provided on the back surface side of the laid carpet mat. There is a method to prevent the movement of the laid carpet mat. However, in this method, work for attaching the female metal fittings and the male metal fittings to proper positions is required, and the mounting and demounting operation of the metal fittings is complicated, so that the method is carried out with only a few vehicle types.

For this reason, at present, as shown in FIGS. 5 and 6, for example, when molding the backing material 3 made of rubber, thermoplastic elastomer or the like, or when the carpet and the backing material 3 are used. When they are formed at the same time as lamination, a large number of conical or cylindrical anti-slip projections 8 are formed on the back surface 3a side of the backing material 3 and aligned in large numbers. Such a conical protrusion has a comb shape, and a tip portion 9 thereof is sharp. According to this, in addition to the anti-slip effect is obtained, the manufacturing cost is low,
Easy handling such as desorption.

[0006]

However, since the non-slip projections of the conventional method have a comb-like shape, the raised hair of the carpet constructed on the floor surface is caught in the loop pile. In the case of a needle punch carpet, a certain degree of anti-slip effect can be obtained, but in the case of a cut pile having no catch, the anti-slip effect is halved. In addition, even in cut piles and needle punched carpets with hooks on the protrusions, the anti-slip protrusions made of a hard material exert an anti-slip effect, but the anti-slip protrusions made of a soft material cause the hips of the protrusions to bend slightly due to the sliding force. However, there is a problem that the anti-slip effect is slightly reduced.

An object of the present invention is also to provide a laid carpet mat provided with a backing material made of rubber, thermoplastic elastomer or the like, even if the raised carpet of the floor surface has a shape that is unlikely to be caught like a cut pile. It is to obtain a high anti-slip effect and to increase the resistance of the laid carpet mat to movement regardless of the type of raising.

[0008]

SUMMARY OF THE INVENTION The present invention provides a stationary carpet mat comprising a carpet body and a backing material laminated on the back side of the carpet body,
Non-slip projections are aligned on the back surface of the backing material, and each of these anti-slip projections includes a base projection protruding from the back surface of the backing material and a plurality of small projections protruding from the top surface of the base projection. Each of the small projections is obliquely outward with respect to the top surface portion of the base projection when viewed from the center point of the top surface portion of the base projection. .

According to the laid floor carpet mat according to the present invention, since a plurality of small protrusions are provided on the top surface of the base protrusion on the backing material side, a very large number of small protrusions for slip prevention are formed. It is a composition. Moreover, each of these small protrusions projects obliquely outward with respect to the top surface portion when viewed from the center point of the top surface portion. Therefore, a large number of small projections are driven obliquely downward in all directions in all directions in the raised direction of the carpet on the floor surface. For this,
The resistance of the carpet mat to sliding is great,
It has a very large anti-slip effect. By making each of the small protrusions protrude from the outer peripheral edge of the top surface portion, the holding force for raising the carpet is maximized.

To further explain, as described above, the small projections are driven obliquely downwards in all directions of each direction into the raised portion of the floor carpet.
For this reason, if a stress is applied to a fixed carpet mat in a certain direction, the small protrusions that are driven obliquely downward so as to extend parallel to the direction of this stress are It has the property of further slipping into the raised fabric, and has the effect of preventing the carpet carpet mat from rising and strengthening the slip prevention. In addition, the small projections in the state of being struck in the naps in the diagonally forward direction and in the diagonally downward direction with respect to the direction of stress, since they extend in the diagonal direction or the direction perpendicular to the direction of stress, Each of the small projections is entangled in the form of holding the raised hair sideways, and has an action of preventing slippage. In this way, when stress is applied to the laid carpet mat, each small protrusion exerts a different anti-slip action, which effectively prevents the laid carpet mat from moving against stress in any direction. can do.

In order to further improve such action and effect, it is preferable that each of the small projections is a wedge-shaped small projection, which makes it particularly easy for the small projections to be entangled in the interior of the raised hair. Further, three or more (preferably 10 or less) small protrusions are provided for each base protrusion, and each small protrusion extends in a point-symmetrical direction when viewed from the center point of the base protrusion. Preferably, this facilitates exhibiting the anti-skid effect against stress in all directions.

According to the laid carpet mat according to the present invention, since it has a large number of small projections having the above-mentioned two types of anti-slip action, it is possible to fluff loop piles and needle punched hairs that have many entangled parts to be caught. The anti-skid effect is further improved, and the resistance to stress in all directions is improved. However, even in cut pile naps with few entangled parts that become hooked parts, especially since it contains many small protrusions that have the property of entanglement by holding the cut pile naps sideways, it is possible to obtain a slip prevention effect that is practically safe for the first time. Was given.

Further, in the non-slip protrusion of the present invention,
Compared to the conventional conical or cylindrical anti-skid projections shown in FIGS. 5 and 6, the base projection and the small projection must be low, but a combination of these both The protrusion as a whole can be made high enough to exert a non-slip effect. In addition, although each small protrusion is small, each small protrusion is supported by the base protrusion, and therefore each small protrusion has a strong waist despite its small size. It has an effect.

From these viewpoints, the height of the base protrusion is particularly preferably 1.0 to 2.0 mm. Further, it is particularly preferable that the size of each small protrusion is 2.0 to 4.0 mm. Further, the total height of the anti-slip projections including the base projection and the small projections is particularly preferably 3.0 to 4.0 mm.

In each of the above-mentioned embodiments, the outer shape of each base protrusion is a low cylinder, but it may be a low triangular prism or a quadrangular prism, for example. In particular, in order to prevent the protrusions from becoming settled against slip stress, it is preferable that the ratio of the height of the base protrusions to the diameter is 1: 0.5 or less. Also, in order to increase the amount of small protrusions entangled in the lower carpet and to firmly bond the laid carpet mat to the raised hair, the ratio of the height to the diameter of the base protrusion should be 1: 0.2 or more. Is preferred.

As the carpet body 2, a carpet manufactured by various braiding methods using natural or synthetic fibers is used. In the carpet body 2, the raised hairs 2a are braided by the base cloth 2b. In the drawing, 10a is a decorative stitching portion of the carpet body 2, and 10b is a back thread of the decorative stitching portion.

When the backing material 3 is formed of rubber, a rubber composition is used in which various rubber agents are blended so as to meet the performance required for natural rubber or various synthetic rubbers. First, it is possible to vulcanize and form a backing material 3 having anti-slip projections having a predetermined form, which will be described later, and attach the backing material 3 to the back surface side of the carpet main body 2 to laminate them. Alternatively, a sheet of the above-mentioned rubber composition is laminated on the back surface side of the carpet main body 2, and the laminate is heated and pressed to accelerate the vulcanization molding of the rubber composition, and at the same time, to form the vulcanized rubber. The backing material 3 can be laminated or bonded to the carpet body 2.

When the backing material 3 is formed of a composition of a thermoplastic elastomer such as soft vinyl chloride, a sheet of the composition of the thermoplastic elastomer is formed, and the sheet is preheated and softened. The backing material 3 is obtained. The backing material 3 is laminated in conformity with the back surface of the carpet body 2, and the laminated body is cooled while being compressed by using a molding die to bond the both, and at the same time, the back surface 3a side of the backing material 3 is provided. Then, a non-slip protrusion having a predetermined shape described later is formed.

In the embodiment shown in FIGS. 1 to 3, each projection 4A is provided with a large number of base projections 5A which are regularly arranged. The shape of each base protrusion 5A may be various low prismatic shapes or cylindrical shapes. Top surface part 1 of each base protrusion 5A
Each small projection 6A so as to project obliquely outward from the peripheral portion of 1
Are formed. In the present embodiment, the planar shape of each base protrusion 5A is circular, and each small protrusion 6A extends in a point-symmetrical direction when viewed from the center point of the base protrusion 5A.
Is extending.

In this embodiment, since the base protrusion 5A has a cylindrical shape, the three small protrusions 6A extend from the outer peripheral portion of the top surface portion 11 of the base protrusion 5A at equal intervals. However, when the base protrusion 5A has a prismatic shape, the top surface portion of the base protrusion 5A has a square shape or a rectangular shape. Make the small protrusion protrude. As a result, each small protrusion extends in the direction symmetrical with respect to the center point of the top surface.

The projecting angle of each small protrusion is preferably 40 ° to 50 ° with respect to the top surface portion 11, whereby the anti-slip effect is most improved, and the forming and operation of the molding die are facilitated. Become.

Also, unlike the present embodiment, the area of the top surface of the base protrusion can be made smaller than the area of the base protrusion on the back surface 3a side, that is, the shape of the vertical cross section of each base protrusion can be changed. It can be trapezoidal.

Further, in the embodiment of FIGS. 2 and 3,
A concave portion 7A recessed from the top surface portion 11 is formed in the central portion of the base protrusion 5A. Therefore, each base protrusion 5A has a hollow cylindrical shape, that is, a flat cylindrical shape (ring shape). ing. As a result, compared with the case where each base protrusion is columnar, each base protrusion and each small protrusion are more likely to sneak into the nap and become entangled.

In the embodiment of FIG. 4A, the base protrusion 5B of each protrusion 4B has a substantially cylindrical shape, and extends from the outer peripheral edge of the top surface portion 11 of the base protrusion 5B toward the outside. In addition, four small protrusions 6B are formed. The small protrusions 6B each have a wedge shape, and the adjacent small protrusions 6B are formed on the outer peripheral edge of the top surface portion 11 at equal intervals. As a result, the resistance to sliding stress in all directions is further improved, compared with those in FIGS.

In the embodiment of FIG. 4 (b), the base protrusion 5C of each protrusion 4C has a substantially columnar shape, and extends outward from the outer peripheral edge of the top surface portion 11 of the base protrusion 5C. In addition, four small protrusions 6C are formed. The small protrusions 6C each have a wedge shape, and the adjacent small protrusions 6C are formed on the outer peripheral edge of the top surface portion 11 at equal intervals. Further, a concave portion 7C recessed from the top surface portion 11 is formed in the central portion of the base protrusion 5C, so that each base protrusion 5C has a flat cylindrical shape.

The protrusion 4D, the base protrusion 5D, and the small protrusion 6D shown in the embodiment of FIG. 4C are the same as those of FIG. 4A, but the protrusion 4D, the base protrusion 5D, and the small protrusion 6D are the same. 4A is slightly different from that in FIG. 4A, and the ratio of the size of the small protrusion 6D to the size of the base protrusion 5D is smaller than the ratio of the size of the small protrusion 6B to the size of the base protrusion 5B in FIG. 4A. It is larger than the ratio.

The protrusion 4E, the base protrusion 5E, the small protrusion 6E, and the recess 7E shown in the embodiment of FIG. 4D are the same as those of FIG. 4B, but the dimensional ratio is as shown in FIG. 4B. Is slightly different. That is, the ratio of the size of the small protrusion 6E to the size of the base protrusion 5E is larger than the ratio of the size of the small protrusion 6C to the size of the base protrusion 5C in FIG. 4B.

In the present invention, each protrusion can be formed by the following method. In the molding die, the recesses for molding the respective base protrusions are arranged in a pattern and are recessed. A knurled roll having an aligned convex portion for forming the base protrusion is used. Roll the knurled roll on the steel plate or aluminum plate for the mold while strongly pressing it. This process is repeated to form a recess in the mold (knurling method). The depth of the recess formed in the mold by this knurling method is usually about 0.5 to 1.7 mm, and the bottom area is 25 mm ² or less, so for a large number of base protrusions. The molding recess is formed. In accordance with each of the configurations shown in FIGS. 1 to 4, a recess for forming a small protrusion is provided in each recess by using a chisel, so that the anti-slip protrusion of each embodiment is formed. A molding die for forming is obtained.

In one embodiment of the present invention, first, the carpet body 2 is prepared by cutting the original fabric of the carpet into a desired shape. Next, the rubber composition of the backing material 3 is rolled using a calender roll to obtain a sheet having a thickness of 1.8 mm, for example. The thickness of this sheet is preferably, for example, 1.5 to 2.0 mm. This sheet is cut into a desired shape and the carpet body is prepared.

Next, a lower die for forming the anti-slip projections shown in FIGS. 2 and 3 and an upper die used as a pair with the lower die are combined in a press type laminated vulcanization molding machine. Install on the upper heating plate or lower heating plate. The carpet 2 prepared for the above-mentioned preparation by the method for producing a laminated product disclosed in JP-B-63-47611 or JP-B-63-47612.
