Description

  The present invention relates to a bath lid placed on a bathtub.

  Conventionally, there is a bath lid configured to cover a bathtub by abutting end portions of a plurality of plate-shaped bath lids.

  As such a bath lid, there is known a structure having a basic performance such as rigidity and heat insulation that does not break even when a large load is applied to the bath lid. For example, it is a structure in which a hard resin plate is provided on the entire front and back surfaces of the core material in order to make the core material a foamed resin plate having high heat insulation properties.

  However, in this structure, there is a problem that the hard resin plates provided on the entire front and back surfaces are heavy and difficult for the elderly to handle, and the weight of the bath lid is required to be reduced.

Japanese Utility Model Publication No.2-119086

  In order to reduce the weight so that the bath lid can be handled with one hand, it may be possible to remove the resin plates provided on the front and back surfaces of the bath lid.

  However, in the configuration with only the foamed resin core material excluding the resin plate, if the infant accidentally gets on the bath lid, the foamed resin will crack or bend and slide into the bathtub. There is a concern that

  Therefore, in order to prevent sliding from the bath lid while maintaining the weight reduction, as disclosed in Patent Document 1, it is formed of metal, alloy or hard resin over the entire core material made of foamed resin. A structure can be considered in which a plurality of hollow reinforcing rods are incorporated so as to give overall rigidity.

  On the other hand, even if the bath lid has increased overall rigidity, there is a risk that if the person gets on top when the installation position on the bathtub is shifted, the bath lid will come off the bathtub and the person may fall into the bathtub. is there. Therefore, manufacturers and sellers of bath lids have written a caution not to get on the bath lid in the instruction manual etc., and forbid the act. However, a bath lid that has rigidity as a whole has a sense of stability even when the user puts it on the top, so that the user tends to get on even if the user is prohibited from riding on the bath lid.

  The present invention has been made in view of the above problems, and in a bath lid of a type in which end portions are abutted with each other, while maintaining the light weight, it is intuitively understood that it should not be ridden on the bath lid. However, an object of the present invention is to provide a bath lid that can improve safety by preventing a child or a user who has accidentally got on the tub from slipping into the bathtub.

  The bath lid of the first invention is a bath lid that is placed on the three sides of the bathtub and is configured to cover the bath against the other bath lid, and has a compression set of 20% or less and flexibility. A main body having a foamed resin core material, and the main body does not include a reinforcing resin plate on the front and back surfaces, and is configured to allow bending with respect to a vertical load. In addition, by providing a slip prevention portion on the contact surface during bending, which is the surface of the body portion that contacts the bathtub only when a vertical load is applied, when the vertical load is applied to the body portion, A gap in the vertical direction between the abutting end and the other bath lid to be a mating partner is suppressed by suppressing the bending deformation at the abutting end that is the end of the main body that abuts against the other bath lid. Suppress the occurrence of Characterized in that, characterized by.

According to the first invention, the foamed resin core material is configured so that the compression set is 20% or less and has flexibility, and further, the reinforcing resin plate is not provided on the front and back surfaces of the main body. In this configuration, bending with respect to a vertical load is allowed. For this reason, the bending that occurs when a vertical load is applied to the main body allows the user to intuitively recognize that the user should not get on the bath lid, and has a deterrent against the act of the user getting on the bath lid. It can be demonstrated.
Examples of the foamed resin capable of forming a foamed resin core material having a compression set of 20% or less and flexibility in the present invention include, for example, foamed polypropylene, foamed polyethylene, soft foamed urethane, foamed EVA (Ethylene-Vinyl Acetate). Hybrid foam material made of polypropylene or polyethylene, expanded polyvinyl chloride, elastomer foam, rubber foam, and the like are included. On the other hand, styrene foam, hard foamed urethane, etc. are not included because they are hardly bent at the thickness required for the core material of the bath lid.

  According to the first invention, even if an infant or a user gets on the bath lid, when the vertical load acts on the bath lid and the bath lid is bent, the slip is automatically prevented. The part comes into contact with the bathtub. The frictional force of the contact surface between the anti-slip part and the bathtub acts as a resistance force when the end of the bath lid placed on the three sides of the bathtub slides from the top of the bathtub to the inside of the bathtub. The bending deformation of the butt end portion can be suppressed. For this reason, even if an infant or a user gets on the bath lid, a gap that may cause the user to slide into the bathtub is generated in the portion that is in contact with another bath lid. Can be prevented.

  According to a second aspect, in the first aspect, the surface of the anti-slip portion is placed in contact with the bathtub in a state in which the main body is placed on the bathtub and no vertical load is applied to the main body. It is above the contact surface of the main body part.

  According to the second invention, when the bath lid is moved horizontally and removed from the bathtub, the bath lid placed on the bathtub comes into contact with the surface of the anti-slip portion in a state where no vertical load is applied to the main body portion. Since it does not contact the bath surface and the resistance of the anti-slip portion does not act on the bath lid, workability is not impaired.

  According to a third aspect, in the second aspect, the anti-slip portion is provided at least on the contact surface at the time of bending near the butted end portion.

  In order to suppress the bending deformation of the butt end portion, it is most effective to apply a tensile force from both ends of the butt end portion. Therefore, according to the third invention, since the anti-slip portion is provided on the contact surface at the time of bending at least near the butt end portion, the frictional force on the contact surface between the anti-slip portion and the bathtub when a vertical load is applied. Thus, a tensile force can be applied from both ends of the butt end portion. For this reason, generation | occurrence | production of a clearance gap can be suppressed more reliably and the safety | security when an infant or a user gets on the bath lid can be improved more.

  According to the present invention, while maintaining the light weight, it is possible to intuitively know that it should not be ridden on the bath lid, but still prevent the infant or the user who has ridden accidentally to the bathtub. Thus, a bath lid that can improve safety is provided.

  Hereinafter, embodiments will be described with reference to the drawings. In the drawings, the same elements are denoted by the same reference numerals.

FIG. 1 is a schematic plan view of a bath lid 13 according to the embodiment.
FIG. 2 is a schematic cross-sectional view of the bath lid 13 of the embodiment, and corresponds to the AA cross section in FIG.
FIG. 3 is a schematic cross-sectional view of the bath lid 13 placed on the rim of the bathtub 100.
FIG. 4 is a schematic diagram showing a state where an infant rides on the bath lid 13 and the bath lid 13 is bent.

  According to the embodiment, the two bath lids 13 are combined to block the opening of the bathtub and prevent the heat of the hot water stored in the bathtub from escaping to the outside.

  In a plan view when viewed from above, the bath lid 13 is formed in a substantially square shape. The two bath lids 13 are arranged side by side in the longitudinal direction of the bathtub, and are placed so that the three sides excluding the side on the butted end side are passed to the upper surface of the rim of the bathtub.

  As shown in FIG. 2, the bath lid 13 includes a main body 20 that occupies most of the bath lid 13, and an edge member 90 that covers the side surfaces of the three sides other than the butted ends of the main body 20. .

  The main body 20 includes a plate-shaped core material 21, a surface sheet 23 covering the front and back surfaces of the core material 21, and a stretched sheet 22 provided between the front and back surfaces of the core material 21 and the surface sheet 23. Have.

  The core material 21 is formed in a thin plate shape having a substantially rectangular planar shape, and has a front surface, a back surface on the opposite side, and a side surface (peripheral surface) formed along the outline of the core material 21.

  The core material 21 is made of a foamed resin that is elastically deformed when an external force is applied. For example, the core material 21 has a compression set of 20% or less calculated by a measurement method defined in JIS K6767, and further has flexibility. The compression set is a strain that remains in a material when a load is applied to the material and then the load is removed.

  Examples of the foamed resin used for forming a core material having a compression set of 20% or less and having flexibility include foamed polypropylene, foamed polyethylene, soft foamed urethane, foamed EVA (Ethylene-Vinyl Acetate), polypropylene and polyethylene. Hybrid foam material, expanded polyvinyl chloride, elastomer foam, rubber foam and the like. In the embodiment, for example, foamed polypropylene (EPP) obtained by foaming beads having a thickness of 20 mm is used as the core material 21.

  For example, the compression set of expanded polypropylene obtained by bead foaming at 30 to 60 magnifications is about 8% to 11%. On the other hand, examples of the foamed resin having a compression set exceeding 20% include rigid urethane foam, polystyrene-based resin foamed by extrusion foaming or foaming bead method. For example, the compression set of expanded polystyrene (EPS) foamed with beads at 30 to 60 times is about 21% to 24%. When the core material 21 is molded with a foamed resin having a compression set exceeding 20%, the dent generated in the core material 21 does not return to the original, and irregularities are generated on the front and back surfaces of the bath lid 13. Not suitable.

  The front and back surfaces of the core material 21 are covered with the surface sheet 23 via the stretched sheet 22 and are not exposed to the outside. The top sheet 23 protects the front and back surfaces of the core material 21 and also functions as a decorative surface.

  The top sheet 23 is thinner than the core material 21 and is made of, for example, an olefin resin sheet having a thickness of 0.25 mm. The top sheet 23 has elasticity that elastically deforms when an external force is applied. Moreover, the surface sheet 23 has non-water permeability.

  The stretched sheet 22 is thinner than the core material 21 and the top sheet 23. The stretched sheet 22 has a thickness of 0.15 μm, for example. The stretched sheet 22 has a linear expansion coefficient smaller than that of the top sheet 23, and is, for example, a fiber cloth of polypropylene or polyethylene.

  The stretched sheet 22 is adhered to the front and back surfaces of the core material 21 by an adhesive or heat fusion, and the stretched sheet 22 is in close contact with the front and back surfaces of the core material 21. Further, the surface sheet 23 is adhered to the surface of the stretched sheet 22 with an adhesive, and the surface sheet 23 is in close contact with the surface of the stretched sheet 22.

  The edge member 90 covers the side surfaces of the three sides other than the butted end portion in the main body portion 20. The edge member 90 includes a protective portion 92 made of a soft resin and a reinforcing portion 91 made of a hard resin that is harder than the protective portion 92.

  The reinforcement part 91 consists of olefin resin, such as a polypropylene and polyethylene, for example. The protection part 92 consists of an olefin type elastomer, for example.

  The reinforcing portion 91 is formed in a band plate shape and is provided along the side surface (peripheral surface) of the main body portion 20. The reinforcing portion 91 is provided between the side surface of the main body portion 20 and the protection portion 92 and is not exposed to the outside.

  The protection part 92 continuously covers a region extending from the side surface of the main body part 20 to the outer edge of the front and back surfaces of the main body part 20. That is, the protection part 92 covers the corner part formed by the front and back surfaces and the side surface of the main body part 20.

  The rim material 90 is placed on the bathtub rim, exhibiting a bending strength greater than that of the main body 20 against the stress that tends to warp the main body 20 due to a temperature difference between the inside of the bathtub and the bathroom. The main body 20 is reinforced so that the peripheral edge of the main body 20 does not warp.

  The two bath lids 13 cover the opening of the bathtub by combining the butted ends of each other. An anti-slip portion 51 is provided at the abutting end portion as a gap generation suppressing means.

  As will be described later, the anti-slip portion 51 is bent at the butt end when a vertical load is applied to the main body portion 20 of the bath lid 13 which is placed on the bathtub rim by abutting the butt ends. Deformation is suppressed, and the occurrence of a vertical gap that occurs when the butted end of one bath lid 13 and the butted end of the other bath lid 13 are separated in the vertical direction is suppressed.

  The anti-slip part 51 is provided on the back side of the main body part 20. The anti-slip part 51 is a soft material such as gel, rubber, or elastomer resin.

  The anti-slip part 51 is continuously provided on the outer peripheral side of the main body part 20 along the three sides other than the butt end part.

  The exposed surface of the anti-slip portion 51 (the lower surface in FIG. 3) is a contact in which the back surface on the outer peripheral side of the bath lid 13 is in contact with the rim of the bathtub 100 when the bath lid 13 is placed on the rim of the bathtub 100. A space 52 is formed below the anti-slip portion 51 so as to be positioned above the surface.

  When the main body 20 is in the state shown in FIG. 3 where no vertical load is applied from above, the infant rides on the bath lid 13 as shown in FIG. 13 has a contact surface at the time of bending that contacts the rim of the bathtub 100 only when a vertical load acts from above and the bath lid 13 is bent. An anti-slip portion 51 is provided on the contact surface during bending.

  That is, as shown in FIG. 3, the slip prevention unit 51 is not in contact with the rim of the bathtub 100 in a state where the vertical load does not act on the bath lid 13 and is not bent.

  Then, as shown in FIG. 4, when an infant rides on the bath lid 13 and a vertical load acts on the bath lid 13 from above and the bath lid 13 bends, the anti-slip portion 51 moves along with the rim of the bathtub 100. To touch.

  According to the embodiment, the front and back surfaces of the main body portion 20 are not provided with a hard resin decorative plate or a reinforcing plate. Therefore, the bath lid 13 according to the embodiment is light in weight, and the handleability is improved.

  The core material 21 has a compression set of 20% or less and has flexibility, and is configured to be allowed to bend with respect to a vertical load. In other words, the external force applied to the bath lid 13 during normal use is not elastically deformed and is not elastically deformed. For this reason, even if the core material 21 is temporarily deformed by an external force, the core material 21 is immediately returned to the original state, and the bath lid 13 is not left locally depressed or greatly deformed.

  Further, the top sheet 23 and the stretched sheet 22 also have elasticity that elastically deforms following the core member 21 when an external force is applied. For this reason, the surface sheet 23 and the stretched sheet 22 do not hinder elastic deformation in which the core material 21 dented by an external force returns.

  Moreover, since the extending | stretching sheet 22 is an extending | stretching raw material, its linear expansion coefficient is lower than the surface material sheet | seat 23, and suppresses the curvature by the bimetal which generate | occur | produces the heat of hot water. Further, the stretched sheet 22 has high tensile strength and flexural modulus, and can increase rigidity even if it is relatively thin.

  In addition, the peripheral edge of the main body 20 is a portion placed on the upper surface of the bathtub rim, but the edge member 90 supports the main body 20 so that the peripheral edge does not warp. The clearance gap produced between the lid | cover 13 and the bathtub rim upper surface can be suppressed, and high heat retention capability can be exhibited.

  The protective part 92 that is a part exposed to the outside in the edge member 90 is made of a soft resin to soften the contact with a person or other components in the bathroom, while the reinforcing part 91 made of hard resin makes the main body part 20 Bending strength greater than that of the main body portion 20 is exerted against the stress that tends to warp the peripheral edge portion.

  In addition, the core material 21 is configured so that the compression set is 20% or less and has flexibility, and further, the front and back surfaces of the main body 20 are not provided with a resin plate for reinforcement, so that bending with respect to a vertical load is allowed. It is configured to be. For this reason, the bending that occurs when a vertical load is applied to the main body 20 can make the user intuitively recognize that the user should not get on the bath lid 13. Deterrence can be demonstrated.

  Further, even if an infant or a user gets on the bath lid 13, if a vertical load is applied to the bath lid 13 and the bath lid 13 bends, as shown in FIG. The prevention part 51 contacts the rim of the bathtub 100. The frictional force of the contact surface between the anti-slip portion 51 and the rim acts as a resistance force when the end of the bath lid 13 slides from the top of the rim to the inside of the bathtub, and the bending deformation of the main body portion 20 can be suppressed.

  By suppressing the bending of the butted ends, a vertical gap is generated between the butted ends of the pair of bath lids 13 that may cause the user to slide down into the bathtub. Can be prevented. According to the embodiment, even when an infant accidentally rides on the main body 20, it can be prevented from sliding into the bathtub with a simple configuration.

  Thus, according to the embodiment, while maintaining the light weight, while preventing the user from slipping into the bathtub, it is possible to intuitively know that the user should not get on the bath lid. A high bath lid can be realized.

  In addition, for example, users who are short are often moved horizontally by moving the bath lid to the washroom side and removing the bath lid. According to the embodiment, in the state (FIG. 3) in which the main body portion 20 is placed on the bathtub rim and no vertical load is applied (not bent), the main body portion 20 is above the surface that contacts the rim of the bathtub. An anti-slip portion 51 is provided.

  Therefore, as shown in FIG. 6, when the bath lid 13 is removed from the bathtub 100 by horizontally moving from the mounting position indicated by the two-dot chain line as indicated by the solid line, the surface of the anti-slip portion 51 is placed on the bathtub rim. It does not contact, the resistance of the slip prevention part 51 does not act on the bath lid 13, and workability is not impaired.

  In order to suppress the bending deformation of the butt end, it is most effective to apply a tensile force in the direction of the white arrow in FIG. 4 from both ends of the butt end. Therefore, according to the embodiment, since the anti-slip portion 51 is provided on the aforementioned contact surface at the time of bending, at least in the vicinity of the abutting end portion, the generation of a gap can be more reliably suppressed, and the user gets on the bath lid. The safety in the case of being stuck can be further increased.

  That is, as shown in FIG. 7, even if the anti-slip portion 51 is provided only on the contact surface at the time of bending near the butt end portion, it is effective for suppressing the bending deformation of the butt end portion.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
