Description

[Detailed Description of the Invention] Industrial Field of Application This invention relates to a bath seat consisting of a seat body and a synthetic resin foam bottom plate attached to the upper surface of the seat body.

BACKGROUND ART Bath seats made of molded hard synthetic resin are commonly used, but they have the drawbacks of feeling cold when sitting on them, being hard and uncomfortable to use, and being slippery.

Therefore, as a means to overcome these drawbacks, attempts have been made to attach a bottom plate made of closed-cell synthetic resin foam to the upper surface of the seat and fix it with suction cups or adhesives. For example, Japanese Utility Model Publication No. 52-41502 proposes a bath mat having a structure in which a suction cup is attached via a short strip to the edge of a through hole provided in the center of a floor plate made of foam or the like.

Problems to be solved by the invention However, in the above-mentioned proposal using a suction cup, the suction cup is attached to the back surface of the upper plate through a hole provided in the center of the upper plate of the seat body.
There are problems in that it takes a lot of effort to put on and take off, the short belt is easy to break, and its durability is poor, and the applicable seat main body is limited to one that has the above-mentioned water drain hole. In addition, when a suction cup is attached directly to the back of the floorboard, it is difficult to attach or remove the suction cup because the suction force is large, and when you sit on it, the suction cup feels like a hard foreign object, making it difficult to use. It has the disadvantage that it is evil.

On the other hand, adhesive methods have the disadvantage that if the structure is partially bonded using a pressure-sensitive adhesive or the like, it cannot be removed for cleaning, and if the entire surface is bonded during the manufacture of the seat, it cannot be applied to existing seats.

Means for Solving the Problems This idea was made in view of the above-mentioned circumstances, and it is very easy to attach and detach the floor plate made of synthetic resin foam, and it can be applied to existing seats without any problems. The purpose of the present invention is to provide a bath seat with a high fixing strength of the bottom plate when worn.

That is, in order to achieve the above-mentioned purpose, the bath seat according to this invention includes a floor plate in which a polyvinyl chloride sheet is embedded in closed-cell polyethylene foam, and a hard synthetic resin molding to attach this floor plate to the upper surface. A suction member comprising a seat main body made of a material, and a recessed portion exposing the polyvinyl chloride sheet on the bottom surface is formed at at least one place on the back surface of the bottom plate, and a group of small suction cups are integrally protruded into the recessed portion. are glued together.

Function of the invention In the bath seat of this invention, the group of small suction cups attached to the back of the bottom plate exhibits a large suction force as a whole, but the individual small suction cups that make up the group have only a very small suction force. . Therefore, this bottom plate is strongly adhered to the seat main body when in use, and there is no possibility of it shifting laterally. On the other hand, when removing the bottom plate from the main body for purposes such as cleaning, if you pull it off from one end side, the small suction cups will come off sequentially from the peeling side, so you do not need much force. In addition, when you sit on this floor plate, the small suction cups that are weak are scattered around the mounting area of the small suction cup group, so you don't feel like a hard foreign body like the mounting area of normal large suction cups, giving you a good feeling of use. is obtained.

In addition, while the polyethylene foam for the bottom plate has the advantage of being highly flexible and provides a good feeling of use, the polyvinyl chloride for the suction member is suitable for forming small suction cup groups due to its moldability and airtightness. However, both materials have the disadvantage that they are difficult to adhere to each other and do not have sufficient adhesive strength to perform a suction cup action. However, in this invention, the polyvinyl chloride sheet embedded in the polyethylene foam of the floor plate becomes the adhering surface of the adsorption member, and since they are made of the same material, it is easy to bond and high adhesive strength is obtained. Extremely strong adhesion can be achieved simply by applying and bonding the adhesive to the surface to be adhered.

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

In Figures 1 to 4, 1 is a box-shaped seat body made of a hard synthetic resin molded product and opened downward, and 2 is a bottom plate attached to the top surface of the main body 1, which is configured on the left and right sides of the back side. Two circular recesses 3,
At the same time, a suction member 4 having a group of small suction cups 4a, 4a... integrally protruding from each of the suction cups 3 is fixed, and a through hole 2a corresponding to a drain hole (not shown) on the top surface of the main body 1 is bored in the center part. There is.

Thus, the bottom plate 2 has an interface in which an upper plate 5 made of closed-cell polyethylene foam and a lower plate 6 made of the same foam and having through holes 6a, 6a constituting the circular recesses 3, 3 are laminated. They are integrated by heat welding at the interface, and band-shaped polyvinyl chloride sheets 7 are sandwiched in the circular recess 3 on both left and right sides of the interface so as to be exposed as the bottom surface.

The suction member 4 is an integrally molded product made of polyvinyl chloride, and has a structure in which a large number of small suction cups 4a, 4a, . . . It is fused to the polyvinyl chloride sheet 7 forming the bottom surface by partially dissolving it by applying a solvent.

In the bath seat constructed as described above, the bottom plate 2 can be fixed by simply pressing the bottom plate 2 against the upper surface of the seat main body 1 at each suction member 4 position, and since it can be easily removed, an existing one can also be used as the main body 1. can.

In order to manufacture the bottom plate of the embodiment structure, as shown in FIG. , 9 to integrate them by heat fusion, the polyvinyl chloride sheet 7 may be sandwiched between the raw sheets of the upper and lower plates 5 and 6. In addition, this polyvinyl chloride sheet 7 is
Since it only needs to be present in the adhesive part of the suction member 4, instead of continuously pinching it in a band shape as described above, a piece of the required length and size may be inserted just in front of the rollers 8, 8. .

Effects of the invention The bath seat according to this invention uses a bottom plate made of closed-cell polyethylene foam, so its insulation properties prevent you from feeling cold when you sit on it, and it is soft and non-slip, giving it an excellent feel. Moreover, since the bottom plate is fixed to the seat body by a group of small suction cups, the bottom plate can be easily attached and removed and can be attached to an existing seat. It has the advantage that there is no risk of

Furthermore, since the suction member is made of polyvinyl chloride, it can be easily molded and manufactured despite its complex shape with a group of small suction cups, and it has a high airtight effect when suctioning the small suction cups and has a long suction duration. In addition, since it is bonded to the polyvinyl chloride sheet embedded in the polyethylene foam of the floorboard, it is easy to bond and has great adhesive strength, and there is no risk of it peeling off from the floorboard, and the small suction cups provide strong adsorption. It can fully demonstrate its power.
