Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a bath mat made of synthetic resin foam that can be fixed to the bathroom floor.

Prior Art and its Problems Bath mats are dangerous because they are slippery when placed on wet floors in bathrooms, so attempts have been made to attach suction cups to fix them to the floor by suction.

However, since tiles are generally used for the floor surface of bathrooms, regular large suction cups have the disadvantage that the airtightness is broken at the grooved joints of the tiles and the suction power is lost. A structure in which a suction base plate with a smooth surface is adhered to the floor surface using a pressure-sensitive adhesive (Utility Model Publication No. 55-47436, No. 55-47437, etc.)
However, when replacing the bath mat, the base plate is difficult to remove and leaves adhesive residue.

Therefore, it is proposed that a group of small suction cups be attached to the back side of the bath mat body instead of the large suction cups mentioned above, so that some of the small suction cups can be attached to the joints of the tiles, and the suction force as a whole can be maintained sufficiently. However, small suction cups made of polyvinyl chloride molding are generally difficult to adhere to the bath mat body made of closed-cell polyethylene foam, and even if they are attached, sufficient adhesive strength may not be obtained. The problem is that it cannot be done.

For this reason, in the past, in order to attach the small suction cup group to the bath mat main body, a ring was provided on the board on which the small suction cup group was integrally formed, and a support shaft inserted from the side of the bath mat main body was inserted through the ring (actually). 1986-
193180), and a hook plate of a reinforcing plate placed on the upper surface of the bath mat is further engaged with the above-mentioned support shaft (Jikko Sho 60-
193182), the reinforcing plate and the substrate are interlocked with each other (Utility Model Publication No. 60-193184), or the overhanging portions on both sides of the substrate are bonded with strip plates (Utility Model Number 60).
-193181) have been proposed, but all of them are structurally complex, require time and effort to manufacture, require high parts and manufacturing costs, and cannot be said to have sufficient mounting strength for small suction cup groups. .

Measures to Solve the Problems In light of the above circumstances, this idea was developed to create a bath mat with a simple structure, which allows small suction cup groups to be attached to the bath mat body very easily and at low cost, and which has excellent attachment strength for the small suction cup groups. is intended to provide.

That is, in order to achieve the above object, the bath mat according to this invention has a polyvinyl chloride layer embedded in key points inside the mat body made of closed-cell polyethylene foam, and the above-mentioned polyvinyl chloride layer is embedded on the back side of the mat body. A recess is formed with the vinyl chloride layer as the bottom surface, and a suction member made of a polyvinyl chloride molded product having a group of small suction cups integrally protruding from the recess is adhered to the recess.

Function of the invention In the bath mat of this invention, the adsorption member made of polyvinyl chloride equipped with a small suction cup is adhered to the polyvinyl chloride layer embedded in the bath mat body. There is no need to use paint or heat treatment, and just by applying a solvent such as thinner to the adhesive surface and bonding, the adhesive interface part dissolves partially and is completely fused and integrated, and there is no risk of interfacial peeling. Since the vinyl chloride layer is embedded inside the bath mat main body, the attachment strength of the adsorption member is extremely high. On the other hand, the body of the bath mat is made of closed-cell polyethylene foam, so it has excellent flexibility and insulation properties, making it comfortable to use.Also, since the suction member is made of polyvinyl chloride, it has excellent moldability and is airtight as a suction cup. sex,
Good adhesion.

Embodiments Hereinafter, this invention will be explained based on illustrated embodiments.

In Figures 1 to 3, reference numeral 1 is the bath mat body, in which a plurality of strip-shaped lower plates 3 made of foam are heat-sealed to the back side of a flat upper plate 2 made of closed-cell polyethylene foam. The lower plates 3a, 3a and the upper plate 2 on both sides are laminated and integrated in a parallel manner.
A polyvinyl chloride layer 4 is embedded in the interface with the polyvinyl chloride layer 4, and circular through holes 5, 5 are formed in the lower plates 3a, 3a at both ends, that is, at the corner positions of the main body 1, so that the polyvinyl chloride layer 4 Circular recesses 6, 6 are formed with the vinyl chloride layer 4 as the bottom surface. Reference numeral 7 denotes a suction member made of polyvinyl chloride molding, and a large number of small suction cups 7b, 7b are provided on one side of the disk-shaped base portion 7a.
...is installed in one piece. The suction member 7 is fitted into each circular recess 6 of the bath mat main body 1, and the other side of the base plate 7a and the polyvinyl chloride layer 4 on the bottom of the recess 6 are coated with a solvent. It is attached to the back side of the main body 1 by fusion bonding.

In order to manufacture a bath mat having the above structure, for example, as shown in FIG. Pass it between rollers 9, 9,
When forming matte original fabric by laminating and integrating them by heat fusion, through-holes 5, 5, etc. are pre-drilled at key points in the original fabric sheet of the lower plates 3a, 3a at both ends, and
A sheet 4a made of polyvinyl chloride is placed between the original fabric sheets of both lower plates 3a, 3a and the original fabric sheet of the upper plate 2.
Continuously sandwich the
is cut along the imaginary line shown in FIG. 5 to form the bath mat main body 1, and then the suction members 7 are fused to each of the formed circular recesses 6 by applying a solvent.

It should be noted that since the polyvinyl chloride layer 4 only needs to be present at the bottom of the circular recess 6, the required size and length can be adjusted in addition to continuously sandwiching the polyvinyl chloride sheet 4a as described above. The pieces may be sandwiched in front of the rollers 9, 9. Further, instead of using the sheet 4a, the polyvinyl chloride layer 4 may be formed by applying molten polyvinyl chloride to the lower surface of the upper plate 2. Furthermore, as shown in FIG. 6, by forming a recess 11 on the upper surface side of the lower plate 3a at the position of the through hole 5, that is, on the joint surface side with the upper plate 2, the slit can be formed in the joint state with the upper plate 2. 1
2, a polyvinyl chloride plate 4b is inserted into the slit 12 to form the polyvinyl chloride layer 4, and the adsorption member 7 is adhered by solvent coating in the same manner as described above.

Effects of the invention The bath mat according to this invention has excellent flexibility and heat insulation properties, is comfortable to use, and can be firmly fixed to a tile floor surface by suction by means of a group of small suction cups of the suction member.

Moreover, since the polyvinyl chloride adsorption member equipped with small suction cups is adhered to the polyvinyl chloride layer buried in the bath mat body, there is no need to use adhesive or heat treatment for this adhesion. By simply applying a solvent such as thinner to the adhesive surface and bonding, the adhesive interface part will be partially dissolved and the adhesive will be completely fused and integrated, so there is no risk of interfacial peeling, and the above vinyl chloride layer is inside the bath mat body. Since the suction member is embedded, the attachment strength of the suction member is high and the suction member has good durability, and also has the advantage that it can be manufactured easily at low cost.
