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 the backing material 3 made of rubber or thermoplastic elastomer is used, or when the carpet body 2 and the backing material 3 are used. When and are formed simultaneously with lamination, a large number of conical or cylindrical anti-slip projections 11 are formed on the back surface 3a side of the lining material 3 and aligned in large numbers. Such a conical protrusion has a comb shape, and its tip 12 is sharp. According to this, the anti-slip effect is obtained, the manufacturing cost is low, and the handling such as desorption is easy.

[0006]

However, since the conventional anti-slip projections are comb-shaped, the raised carpet of the carpet installed on the floor surface has loops with hooks on the projections. In the case of a pile or a needle punched carpet, a certain amount 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 anti-slip projection is a ring-shaped projection having a cavity at the center of the anti-slip projections.
It relates to a stationary carpet mat.

According to the present invention, the non-slip projections are arranged on the back surface of the backing material, and each of the anti-slip projections is
Since this non-slip projection is a ring-shaped projection having a cavity in the center thereof, the ring-shaped projection has a ring-shaped projection on the floor surface as compared with the conventional carpet mat as shown in FIGS. Since it is buried in a large area in the raised hair and the ring-shaped protrusion resists sliding stress, it exerts a great anti-slip effect.

Further, the conventional cone-shaped protrusions have a drawback that when a strong sliding stress is applied to the laid carpet mat, the protrusions bend and the anti-slip effect is reduced. However, according to the ring-shaped anti-slip projection of the present invention, since it has a shape that is difficult to bend, even if a strong sliding stress is applied to the laid carpet mat, it does not bend and exerts a strong anti-slip effect. There is. If this is, for example, a cylindrical shape, it would have to be a very flat projection in order to prevent deformation of the projection due to sliding stress. It has no anti-slip effect for this reason.

2 is a plan view showing a part of the back surface of the mat 1 of FIG. 1, FIG. 3 is a cross-sectional view showing a state of a part of the mat of FIG. 2, and FIG. 4 is an example of a ring-shaped non-slip protrusion. FIG.

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, 7a is a decorative stitching portion of the carpet main body 2, and 7b is a back thread of the decorative stitching portion.

When the backing material 3 is made of rubber, a rubber composition containing various chemicals for rubber so as to meet the performance required for natural rubber or various synthetic rubbers is used. 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 composed of a large number of regularly arranged ring-shaped projections. The outer shape of the protrusion 4A is a substantially cylindrical shape,
A cylindrical cavity or recess 5 is formed in the central portion of the protrusion 4A. The tip portion 8 of the protrusion 4A gradually becomes thinner toward the tip, that is, the thickness of the protrusion becomes smaller and is sharp. Therefore, the inclined surface 6 is formed on the inner side surface of the tip portion 8 and the inclined surface is not formed on the outer side surface of the tip portion 8. This protrusion is shown in FIG.
It is the same as the protrusion shown in (b).

In the embodiment of FIG. 4 (a), the anti-slip projections 4B projecting to the back surface side of the backing material 3 are ring-shaped and have a constant thickness over the entire surface. In the embodiment of FIG. 4C, the outer shape of the protrusion 4C is substantially columnar, but a hollow or recess 5 having a columnar shape is formed in the central portion of the protrusion 4C. The tip portion 9 of the projection 4C gradually becomes thinner toward the tip, that is, the thickness of the projection becomes smaller and is sharp. The inclined surface 6 is formed on the outer side surface of the tip portion 9, and the inclined surface is not formed on the inner side surface of the tip portion 9.

In the embodiment of FIG. 4D, the protrusion 4
D gradually becomes thinner toward the tip, that is, the thickness of the protrusion becomes smaller and is sharp. The cross-sectional shape of the wall forming each part of the ring-shaped protrusion 4D is wedge-shaped, and the tip 10 thereof is sharp. In addition, inclined surfaces are formed on both the outer side surface and the inner side surface of the projection 4D from the base to the tip.

In each of the above-described embodiments, the outer shape of each protrusion is a low columnar shape, but it may be, for example, a low triangular columnar shape or a square columnar shape. In particular, in order to prevent the protrusion from being settled due to slip stress, it is preferable that the ratio of the height to the diameter of the protrusion is 1: 1 or less. Further, in order to increase the amount of wrapping of the protrusions on the lower carpet and to firmly bond the laid carpet mat to the raised hair, it is preferable that the ratio of the height to the diameter of the protrusions is 1: 0.2 or more. Moreover, the height of the protrusion is 2 to 6 m.
The diameter of the protrusion is preferably 6 to 12 mm.

Further, by making the tip portion of each anti-slip projection sharp as shown in FIGS. 2, 3, 4 (c) and 4 (d), or by making the tip thinner, The protrusions enter the raised hair and become easily caught,
The holding power of the stationary carpet mat is further improved.

In the present invention, each protrusion can be formed by the following method. That is, the protrusions are formed by arranging the recesses for molding the protrusions in a pattern on the molding die so as to be aligned in a pattern. Each recess can be formed by removing it with a machine tool. As a result, the molding die for forming the anti-slip projections of each embodiment is obtained.

In one embodiment of the present invention, first, the carpet main 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 1.7 mm, for example. The thickness of this sheet is preferably 1.5 to 2 mm, for example. This sheet is cut into a desired shape, and the carpet body 2 is prepared for preparation.

Next, the lower mold for molding the ring-shaped anti-slip projections 4A shown in FIGS. 2 and 3 and the upper mold used in pair with the lower mold are connected to the upper heating plate of the press-type laminated vulcanization molding machine. Attach to the lower heating plate. Using this device, Japanese Examined Patent Publication No. 63-47611
According to the method for manufacturing a laminated product shown in Japanese Patent Publication No. 63-47612, the carpet body 2 and the sheet of the backing material 3 which have been prepared for preparation are laminated and vulcanized. Next, the laminated vulcanized molded product is cut into a desired shape, the peripheral edge of this is sewn with an overlock sewing machine, and the peripheral edge shown in FIG.

As the rubber constituting the backing material, the rubber composition containing the above-mentioned rubber can be exemplified. A soft vinyl chloride composition can be exemplified as the thermoplastic elastomer constituting the backing material.

[0024]

According to the present invention, the conventional carpet mat having a non-slip projection such as a conical shape is easy to handle, easy to manufacture and low in cost, and it does not impair its advantages. This is a significant improvement in the anti-slip effect on a carpet floor surface.

As a result, there is an effect of improving the driving safety in the driver's seat of a vehicle, which is often requested, and an effect of greatly improving the positional displacement due to an external force such as walking of the laid carpet mat even on other carpet floor surfaces. There is something.
