Stairs.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a staircase for entering a bath tub of a golf course or the like.

[0002]

[Prior art]

 The bath tubs at golf courses and the like are high, which makes it inconvenient for the elderly to take a bath. If concrete stairs made of concrete were provided, the bathroom would be narrowed and there was a risk of slipping on the tiles.

[0003]

[Problems to be solved by the device]

 Therefore, an object of the present invention is to solve the above-mentioned drawbacks of the prior art and to provide a bathing staircase which is lightweight, easy to move, easy to go up and down, has a sense of stability and does not slip.

[0004]

[Means for Solving the Problems]

 The bathing staircase according to the present invention is characterized by being made of a plastic foam, preferably a polyolefin foam. In the bathing stairs of the present invention, it is preferable to form a grain pattern on the upper surface for the purpose of preventing the feet from slipping. A plastic sheet or a rubber sheet may be laminated on the upper surface of the present invention to reinforce the strength of the foam. Vinyl chloride, polyethylene, etc. can be applied as the plastic sheet, and natural rubber and synthetic rubber sheets can be applied as the rubber sheet. As a method for laminating, a method using heat fusion, an adhesive or a pressure-sensitive adhesive can be applied. As the plastic foam of the present invention, various foams such as polystyrene foam and vinyl chloride foam can be applied, but polyolefin foam is preferable from the viewpoint of weather resistance, hardness, elasticity and the like. The base material of the polyolefin foam is an ethylene-vinyl acetate copolymer, an ethylene-propylene copolymer, an ethylene-propylene-diene copolymer, or an ethylene / methyl, ethyl, propyl, butyl acrylate content 45 % Copolymer, or a commercially available high-, medium-, or low-density polyethylene, chlorinated polyethylene, or polypropylene blended with at least one of these copolymers. From the viewpoint of hardness and processability, polyethylene or An ethylene-vinyl acetate copolymer is particularly preferred. The expansion ratio of the polyolefin foam is preferably 10 to 50 times. If the expansion ratio is less than 10 times, the weight is large and the transfer is inconvenient. On the other hand, when the expansion ratio exceeds 50 times, the hardness becomes insufficient, and when it is repeatedly used, the foam tends to shrink.

As a method for producing the polyolefin foam of the present invention, various conventionally known foaming methods can be applied, but a method for producing a thick foam by a two-step foaming method is preferable. The two-stage foaming method suitable for application of the present invention will be described in detail. An appropriate amount of a foaming agent, a cross-linking agent, and if necessary, a foaming aid, a filler and a pigment are added and kneaded to obtain a cross-linking property. The foaming composition is partially decomposed by heating the foamable composition in a mold under pressure, and then the obtained intermediate foam is heated and foamed under normal pressure. The heating conditions of such a two-stage foaming method may be the same as the conventional one (see Japanese Patent Publication No. 45-29381, Japanese Patent Publication No. 2-42649, Japanese Patent Publication No. 3-67613, etc.), for example, in the range of 130 to 200 ° C. It may be appropriately set according to the method to be used, but the heating conditions in the above preferred method are as follows: heating under pressure is in the range of 130 to 160 ° C, and heating under normal pressure is in the range of 140 to 200 ° C. You can set it to. The above-mentioned two-step foaming method is a preferable method and is not particularly limited to the two-step foaming method, and a pressure one-step foaming method, an atmospheric pressure one-step foaming method and the like can also be adopted. Alternatively, thin endless sheets may be laminated. In order to obtain the bathing stairs according to the present invention from the foams manufactured by these methods, it is possible to process them by a method such as cutting, or to make the mold approximately the same size as the bathing stairs, It may be molded in the molding or foaming step. Alternatively, a small piece obtained by cutting a polyolefin foam is heated with hot air or the like to melt its surface, and then overfilled in a compression molding die and compressed to produce a molded article having a desired shape. (See JP-A-59-155019) can also be adopted. Next, a large number of concave portions or convex portions, that is, a grain pattern is formed on the upper surface of the bathing stairs formed into a desired shape by a method such as graining.

【Example】

 Hereinafter, the present invention will be specifically described with reference to the embodiments shown in the accompanying drawings. FIG. 1 is a perspective view showing a bathing staircase 1 according to the present invention. The material is polyethylene foam, and the expansion ratio is about 30 times. A wrinkle pattern 2 is added to each upper surface of the stairs to prevent them from slipping.

[0007]

[Effect of device]

 The staircase for bathing according to the present invention is lightweight and easy to move, and has an anti-slip texture pattern formed on the upper surface, which makes it suitable as a staircase when bathing in a high bathtub such as a golf course. is there.
