Description

Technical Field

[0001] The present invention relates to a bath chair for use in a bathroom.

Background Art

[0002] A chair for people to sit on when washing their body and hair in the bathroom is widely used. This type of chair has a structure in which legs are vertically provided from the lower part of the seat board. It used to be made of wood, but now plastic ones are the mainstream.

[0003] By the way, when not in use, there is usually no place to put the bath chair, so it is common to leave it on the bathroom floor. For this reason, it may get in the way during bathroom cleaning, the washing area becomes narrow when standing up to take a shower, and the legs always contact the bathroom floor, so there is a risk that moisture remains between the floor and the chair, creating a breeding ground for mold.

[0004] In order to solve the above problems, attention has been paid to the fact that steel plates are used for the core material of the wall panel in the currently mainstream unit bathroom, and attempts have been made to attach magnets to the bath chair and fix it to the bathroom wall by magnetic force.

[0005] In Patent Document 1, means for attaching a magnet to a bath chair is disclosed by embedding a magnet in a part of the bath chair or kneading a magnet into a part of the molding material.

[0006] Also, in Patent Document 2, a recess for accommodating a magnet is provided on the side surface of the bath chair, and means for attaching a magnet to the bath chair by closing this recess with a lid is disclosed.

[0007] Furthermore, Patent Document 3 discloses a bath chair in which four legs extending downward from the bottom of the seat board are suspended, and side walls are suspended from the bottom of the seat board between adjacent legs, with a pair of opposing side walls suspended vertically from the seat board, so that when bath chairs are stacked, the lower ends of the pair of side walls abut against the seat board of the lower bath chair, and a magnetic plate with a rubber magnet on its surface for magnetic attraction to magnetic materials is attached to the side of the bath chair. [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] Japanese Patent Publication No. 2001-104194 [Patent Document 2] Japanese Patent Publication No. 2023-013350 [Patent Document 3] Japanese Patent Publication No. 2025-118112 [Disclosure of the Invention] [Problems that the invention aims to solve]

[0009] The invention described in Patent Document 1 has the problem that mixing magnets into a part of the molding material limits the selection of molding materials, and embedding magnets complicates the molding process and increases costs.

[0010] Furthermore, the invention described in Patent Document 2, which involves providing a recess in the side of the bath chair to house a magnet and closing this recess with a cover, has the problem that the thickness of the side wall increases due to the recess housing the magnet, and because it is carried through a cover, a strong magnet is required to ensure sufficient attraction, and thus the cost is high.

[0011] Furthermore, the invention described in Patent Document 3, which involves attaching a magnetic plate with a rubber magnet on its surface for magnetic attraction to a magnetic material to the side of a bath chair, allows the rubber magnet to be exposed on the surface and thus securely attached to the bathroom wall with sufficient strength.

[0012] By the way, the invention described in Patent Document 3 had a problem where, if the bath chair was made larger, the bath chair might slide off the wall unless the magnetic attraction force was strengthened. In this case, the problem could be solved by making the rubber magnet larger, but this bath chair has four legs that extend downward from the bottom of the seat plate, and side walls that extend from the bottom of the seat plate between adjacent legs, and of these side walls, a pair of opposing side walls that extend vertically from the seat plate, so that when the bath chairs are stacked, the lower ends of the pair of side walls come into contact with the seat plate of the lower bath chair, and a magnet plate with a rubber magnet that magnetically attracts magnetic materials is fixed to one of the remaining side walls, so if the rubber magnet is made larger, the vertical length of the side wall increases, which causes the stacking height to increase. [Means for solving the problem]

[0013] The present invention was created with the aim of providing a bath chair that solves the problems of the prior art described above. It features four legs extending downward from the bottom of the seat plate, and side walls extending from the bottom of the seat plate between adjacent legs. Of these side walls, a pair of opposing side walls are extended vertically from the seat plate, so that when bath chairs are stacked, the lower ends of the pair of side walls abut against the seat plate of the lower bath chair. A magnet plate with a rubber magnet on its surface that magnetically attracts magnetic materials is fixed to one of the remaining side walls. The magnet plate is partially provided with an elastic member that has a higher coefficient of friction than the rubber magnet, in an area of ​​20% or less of the surface area of ​​the rubber magnet's adsorption surface. The elastic member is positioned to protrude from the rubber magnet's adsorption surface, so that it compresses and deforms when magnetically attracted to a magnetic material and is pressed against the magnetic material, and the magnetic attraction force of the rubber magnet and the frictional force of the elastic member work together to suppress the slippage of the magnet plate.

[0014] Furthermore, the invention according to claim 2 is characterized in that the elastic member in the bath chair is made of silicone rubber.

[0015] Furthermore, the invention according to claim 3 is characterized in that, in the bath chair, the elastic member is positioned to protrude 0.1 mm to 1.0 mm from the adsorption surface of the rubber magnet.

[0016] Furthermore, the invention according to claim 4 is characterized in that, in the bath chair described above, a rectangular elastic member is placed on top of the rectangular rubber magnet, having the same width as the rubber magnet and a height of 1 / 15 or less. [Effects of the Invention]

[0017] In the bathtub chair of the present invention, an elastic member having a higher coefficient of friction than the rubber magnet is partially provided on the magnet plate within a range of 20% or less of the surface area of the adsorption surface of the rubber magnet. Since the elastic member is arranged to protrude from the adsorption surface of the rubber magnet, it is compressed and deformed when magnetically adsorbed to the magnetic body and pressed against the magnetic body. The magnetic adsorption force of the rubber magnet and the frictional force of the elastic member cooperate to suppress the sliding of the magnet plate.

[0018] Therefore, according to the present invention, it is possible to prevent the bathtub chair from slipping off without increasing the size of the magnet plate, and there is no problem of increasing the stacking height when stacking.

Best Mode for Carrying Out the Invention

[0020] Hereinafter, a specific embodiment of the bathtub chair A of the present invention will be described based on the accompanying drawings. This bathtub chair A is provided with four legs 2, 2, 2, 2 that extend downward from the lower part of the seat plate 1, and side walls are vertically provided between the adjacent legs from the lower part of the seat plate. Among the side walls, a pair of opposite side walls 1A, 1A are vertically provided from the seat plate, and when stacking bathtub chairs, the lower ends of the pair of side walls are configured to abut on the seat plate of the lower bathtub chair. A magnet plate provided with a rubber magnet that magnetically adheres to a magnetic body is fixed to one of the remaining side walls 1B, 1B. This bathtub chair A is molded from polypropylene here, but it is of course not limited to this material.

[0021] Reference numeral B in the figure is the magnet plate. By arranging a protrusion 11 in a downward U-shape on the back surface of the plate body 10 of this magnet plate B, the outside of the protrusion is fitted into a fitting recess on the bathtub chair side described later. On the other hand, a protrusion 3 is arranged in a downward U-shape on the side wall of the seat plate 1 of the bathtub chair, and the region surrounded by the protrusion is used as a fitting recess for the plate body 10 of the magnet plate B.

[0022] An engaging protrusion 14 projects from the center of the back surface of the plate body 10 of the magnet plate B, engaging protrusions 12, 12 project from the left and right of the back surface, and engaging protrusions 13, 13 project from the lower end of the back surface. The engaging protrusion 14 has a triangular shape in side view that becomes thinner upward, and is inserted into and engaged with an engaging hole 6 formed in the fitting recess 6 on the bathtub chair side. The engaging protrusions 12, 12 have an L-shaped shape in side view and are inserted into and engaged with engaging holes 5, 5 formed in the fitting recess 6 on the bathtub chair side. The engaging protrusions 13, 13 have an L-shaped shape in side view and engage with the lower end of the side wall of the seat plate on the bathtub chair side.

[0023] In the figure, reference numeral 16 denotes a rubber magnet. This rubber magnet 16 is adhesively fixed to the surface of the plate body 10 of the magnet plate B using double-sided adhesive tape (not shown). The magnet plate B is rectangular in shape, and a rectangular elastic member 17, which is the same width as the rubber magnet but has a height of 1 / 15 or less, is adhesively fixed to its upper part. The elastic member 17 is positioned to protrude 0.1 mm to 1.0 mm from the adsorption surface of the rubber magnet 16. By being positioned to protrude from the adsorption surface of the rubber magnet 16, the elastic member 17 is compressed and deformed when magnetically attracted to a magnetic material, pressing against the magnetic material. This allows the magnetic attraction force of the rubber magnet and the frictional force of the elastic member to work together to suppress the slippage of the magnet plate, and is provided partially in a range of 20% or less of the surface area of ​​the adsorption surface of the rubber magnet. In the above, protrusions 15 are provided on the circumferential side of the plate body 10, and the rubber magnet 16 and the elastic member 17 are fixed in the area surrounded by these protrusions.

[0024] Here, magnet plate B is assumed to be made of SMMA resin, which has strong adhesion to adhesive tape, but the material is not limited to this; for example, ABS resin with similar properties could also be used. Also, while silicone rubber is assumed for the elastic member 17, the material is not limited to this; any material with elasticity and friction, such as elastomer or sponge-like material, could be used.
