Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stair mat to be laid on stairs.

[0002]

[Problems to be solved by conventional techniques and devices]

 Various stair mats have been proposed and put into practical use for the purpose of preventing slipping or muffling when going up and down stairs. Various materials such as synthetic rubber, polypropylene, woven cloth, and non-woven cloth are used as materials, and various shapes such as those laid only on the corners and those laid on the entire floor surface are also used. In addition, adhesive force, frictional force, etc. are used for the adhesion method. For example, in the case of using synthetic rubber, the anti-slip effect is obtained by utilizing the static friction force of the synthetic rubber on the floor surface, but the anti-slip effect often declines over time, and the sound deadening effect is not very good. Absent.

There is a mat that uses a cushion material for the purpose of obtaining a sound deadening effect, but in this case, an adhesive surface is formed on the back surface in order to obtain an anti-slip effect. A stair mat using such cushion material has a problem that the adhesiveness of the adhesive surface is easily deteriorated by washing. In addition, the adhesiveness often deteriorated by repeated attachment and detachment. The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a stair mat having a good anti-slip effect, a sound deadening effect, and washing resistance by forming an anti-slip layer having a vacuum suction force. To aim.

[0004]

[Means for Solving the Problems]

 The staircase mat according to the present invention is a staircase mat having a non-slip layer on one surface of a staircase mat body made of a cloth or a synthetic resin sheet, characterized in that the staircase mat is provided with a non-slip layer made of synthetic resin and having a vacuum suction force. To do.

[0005]

[Action]

 Since the anti-slip layer formed on the back surface of the staircase mat according to the present invention has good adhesiveness due to the vacuum suction force, a good antiskid effect can be obtained only by placing it on the stairs. On the other hand, it has good peelability and can be easily removed, and the adhesiveness hardly deteriorates even after repeated attachments and detachments, so there is almost no deterioration in the anti-slip effect. Furthermore, since the anti-slip layer has a structure including a large number of bubbles, not only the stair mat body but also this anti-slip layer absorbs vibration, and the sound deadening effect is further improved. In addition, it has excellent wash resistance, and the adhesiveness is less likely to deteriorate with repeated washing.

【Example】

 Hereinafter, the present invention will be specifically described with reference to the drawings showing an embodiment thereof. FIG. 1 is a schematic view of a stair mat according to the present invention, FIG. 1 (a) is a perspective view showing a state of being mounted on a stair, and FIG. 1 (b) is an enlarged sectional view of the stair mat. In the figure, 1 is a staircase mat body made of circular knit pile fabric, and the staircase mat body 1 is a substantially rectangular shape corresponding to the staircase shape, and its corners are rounded. On the back surface of the staircase mat body 1, there is formed a non-slip layer 2 formed by applying a mixture having the composition described later.

The composition of the anti-slip layer 2 in the present invention is as shown in Table 1. Specifically, the synthetic resin (emulsion) is a urethane type product “DICFOAM F-520”, and the foaming agent is “F”. -1 ", 4% concentration of" CMC "as a surfactant," VONCOAT 3750 "as an auxiliary agent (1)," CR-5L "as an auxiliary agent (2)," VONDIC NBA-1 "as an auxiliary agent (3) "," CATALYST PA-20 "was used as a catalyst. "CMC" is manufactured by Dai-ichi Kogyo Seiyaku Co., Ltd., and other products are manufactured by Dainippon Ink and Chemicals Co., Ltd.

[0008]

[Table 1]

The adhesion mechanism of the non-slip layer 2 made of such a material to the floor is the vacuum adsorption force due to the large number of pores formed therein. In other words, if this is suppressed a little, the air in the pores will be exhausted and a decompressed state will be created, which will adhere to the floor.

When the anti-slip layer 2 is applied and formed on the staircase mat body 1, first, the compositions shown in Table 1 are blended and foamed by a mixer. Next, the foamed composition is applied to one surface of the staircase mat body 1 by a coating device. Then, this is put in a dryer and dried at 120 to 160 ° C. for 5 minutes.

At this time, the results of the physical property test of the anti-slip layer 2 when the anti-slip layer 2 was applied by changing the expansion ratio and the coating thickness are shown in Table 2. From Table 2, it can be seen that when the expansion ratio is small, the releasability is good, when the expansion ratio is large, the adhesion is good, and when the coating thickness is increased, both are improved.

The expansion ratio and the coating thickness may be determined from the results shown in Table 2 in consideration of the required balance of performance.

[0013]

[Table 2]

The method of measuring the results shown in Table 2 is specifically as follows. Delamination strength: Sample preparation Apply adhesive (F-520 thickening liquid) to cotton cloth, stick to foam surface, heat-treat and cut into 2 cm width. Measure foam breaking strength by autograph. Cellophane tape peeling strength: Stick cellophane tape (1.8 mm) firmly on the foam surface by hand, peel off instantly in the right angle direction, and check for damage. ○: No abnormality ×: Damage Surface friction strength: Rubbing the foam surface with a Gakushin type friction tester (Flat 500g) and reading the number of times until damage. Adhesion: A 2 cm wide foam sheet is pressure-bonded to a glass plate, and after 1 day, the 90 ° peel strength is measured. Even when the washing was repeated 20 times, there was no change in the adhesion of the anti-slip layer 2.

Next, Table 3 shows other examples of the composition of the anti-slip layer 2 in the present invention. The products used as the composition in Table 3 are the same as those in Table 1.

[0016]

[Table 3]

When the anti-slip layer 2 made of the composition shown in Table 3 is applied and formed on the staircase mat body 1, first, the composition shown in Table 3 is blended and foamed 3.3 times with a mixer. Next, the foamed composition is applied to one surface of the staircase mat body 1 by a coating device. Then, this is put in a dryer and dried at 120 ° C. for 5 minutes and 140 ° C. for 2 minutes. In this case as well, as in the above-described examples, good adhesion to the floor by vacuum adsorption was obtained.

Further, since the non-slip layer 2 is made of, for example, urethane resin having a large number of bubbles, not only the staircase mat body 1 but also the anti-slip layer 2 absorbs the vibration, and the sound deadening effect is obtained. Further improve.

As shown in FIG. 2, the anti-slip layer 2 formed on the back surface of the staircase mat body 1 can have grooves 3, 3 ... Formed at required intervals to adjust the adhesive force. The staircase mat body 1 is not limited to woven fabric, and non-woven fabric can be used, and the material can be widely selected from fibers such as cotton, synthetic fibers such as nylon, and synthetic resin films such as polyester film. If you choose colors and patterns according to your taste, you can get the effect as an accessory to decorate stairs. Furthermore, the staircase mat according to the present invention can be easily cut, and the edge treatment after cutting is not necessary, so that the shape can be freely adjusted to suit each staircase or any desired shape. Moreover, it is possible to further improve safety by mounting the device in a manner to cover the corners.
