Description

  The present invention relates to a bath lid, and more particularly, to a bath lid that can cover a bathtub flange having a raised shape for pillow use without a gap.

  Conventionally, as this kind of bath lid, as shown in FIGS. 6 and 7, hard surface plates 64 and 64 made of thin aluminum plates are laminated and integrated on both upper and lower surfaces of a core plate 63 made of a thermoplastic synthetic resin foam. A bath lid 60 having a configuration in which an edge protector 62 is attached to the peripheral portion of the lid body 61 is known. Specifically, for example, a rod-shaped edge protector 62 is wound around the periphery of the lid main body 61 and joined by an adhesive, or a loop-shaped edge protector 62 slightly shorter than the periphery of the lid main body 61 is used. A configuration is adopted in which the peripheral portion is forcibly fitted and integrally attached.

  By providing such an edge protector 62 at the peripheral edge of the lid main body 61, damage to the peripheral edge of the lid main body 61 can be effectively prevented, and damage to the upper surface of the bathtub due to the exposed end surface of the lid main body 61 is also prevented. be able to. Further, the edge protector 62 can impart a non-slip function to the bath lid 60 itself.

However, since the bathtub body also improves the comfort at the time of bathing, in order to provide a pillow part on the flange of the bathtub body, what the flange surface of the bathtub body was a conventional flat surface was recently inclined, The exciting ones are now on sale. Various ideas have been made to fit the bath lid to the flange surface so that the temperature of the bath lid to be attached to these is as low as possible. For example, there are ones in which the concave groove 71 is formed on the inner surface of the bath lid 73, and one in which the entire lid is formed into a curved shape. In addition, as shown in FIG.

  Even with these improvements, the bath lid has been unable to accommodate the bathtub having a flange surface with a large inclination angle. When the inclination angle is increased, the height difference of the flange is increased, and if the groove corresponding to the height difference is to be formed in the bath lid, the groove must be deepened. If the thickness of the bath lid becomes too thick, the weight of the bath lid increases, and a large force is required when removing the bath lid from the bathtub, which is a burden on the user and has an adverse effect. It was. In addition, it is difficult to form a curved surface shape for the entire lid.

  Therefore, these problems are solved, and the bath lid corresponding to the bathtub having a flange surface with a large inclination angle is used to suppress the increase in the weight of the bath lid by preventing the thickness of the bath lid from being increased, thereby preventing the temperature of the hot water from decreasing. Therefore, we provide a bath lid with improved sealing performance with the bathtub.

  The present invention resides in a bath lid that is mounted on a bathtub flange having a raised portion, and has an opening for containing the raised portion.

  Invention of Claim 2 is a bath lid which has a butting part which abuts against the above-mentioned rising part in the bath lid with which the bathtub flange which has a rising part at the bathtub edge part is equipped, An edge protector and packing are laminated on the periphery, and the packing is in contact with the raised portion at the abutting portion, and the bath lid forms a seal structure between the bathtub flange and the bath lid.

The invention described in claim 3 is the bath lid according to claim 2, wherein the inside of the packing is hollow or foamed resin.

  According to the present invention, in the bath lid to be mounted on the bathtub flange having the raised portion, since the bath lid has an opening for fitting with the raised portion, the flange having a large inclination angle and a large height difference is provided. Even if it has a bathtub, when the flange and the opening are fitted, the flange may protrude from the opening, so there is no need to increase the thickness of the bath lid, and the weight of the bath lid does not increase. effective.

  According to the invention described in claim 2, in the bath lid that is mounted on the bathtub flange having a raised portion at the bathtub end, the bath lid has a butted portion that abuts against the raised portion, and the butted portion Edge protector and packing are laminated on the periphery of the pad, and the packing is in contact with the raised portion at the abutting portion, and is in the bath lid forming a seal structure between the bathtub flange and the bath lid, Even in a bathtub having a flange with a large inclination angle and a large height difference, the bath lid has an abutting portion with a flange, and an edge protector and packing are laminated on the periphery of the abutting portion. When the bath lid is abutted against the flange, the bath lid can securely seal the bathtub, so there is no need to increase the thickness of the bath lid and the weight of the bath lid increases. There is an effect that it is not.

  According to the invention described in claim 3, since the inside of the packing is hollow or foamed resin, the bath lid according to claim 2 has the effect of reducing the weight of the bath lid.

  FIG.1 and FIG.2 is an example which shows embodiment of the bath lid of this invention. In FIG. 1, an opening 7 is provided so that the pillow 5 of the flange 3 of the bathtub 1 body is completely fitted to the bath lid 2. By providing the opening 7, the pillow 5 can be protruded from the opening 7, and the height of the pillow 5 is not limited. Moreover, it is not necessary to increase the thickness of the bath lid 2, and the weight of the bath lid 2 does not increase. Rather, by providing the opening 7, the weight of the bath lid 2 can be reduced, and the bath lid can be easily opened and closed even by an elderly person.

  FIG. 2 shows a bath lid 4 having an abutting portion 9 that abuts against the pillow portion 5. The periphery of the abutting portion 9 is covered with an edge protector 11, and a packing 13 is laminated on the edge protector 11. The packing 13 covers at least the corner 15 of the edge protector 11 on the body side of the bathtub 1. The edge protector 11 and the packing 13 are preferably bonded and integrated with an adhesive. Therefore, when the bath lid 4 is abutted against the flange 3, the bath lid 4 can surely seal the bathtub 1, and therefore the bath lid 4 does not need to be thick, and the bath lid 4 has a heavy weight. There is an effect that it does not increase.

  The main body of the bath lid 2 is decorated as a face plate 8 on both upper and lower surfaces of a core plate made of a thermoplastic synthetic resin foam having a foaming rate of about 15 times, such as polyethylene, polystyrene, polyvinyl chloride, ethylene-vinyl acetate copolymer as a core material. In addition to various hard synthetic resin plates such as baked phenolic resins such as reinforced ABS resin and reinforced ABS resin, metal plates such as aluminum having excellent corrosion resistance and surface cosmetic properties can also be used.

  The edge protector 11 may be a synthetic resin foam or a non-foamed elastic material having a lower foaming rate than the synthetic resin foam of the core material 6. For example, the foaming rate of ethylene-vinyl acetate copolymer or polyethylene is 6 times. Suitable foams, non-foamed polyvinyl chloride, styrene elastomers and the like are suitable. Further, the packing 13 can use the same material as the edge protector 11.

  As a manufacturing method of the bath lid 2, a high-performance one can be manufactured very easily by using a hot press method. That is, in the bath lid 2, as shown in FIG. 3, a total of a pair of upper and lower face plates 8, 8, a core original plate 50 made of a synthetic resin foam having small vertical and horizontal dimensions, and the face plates 8, 8 and original plate 50. The base plate is inserted into the groove portion 30b of the raw material 30 for the edge protector having a thickness larger than the thickness and having a protruding insertion portion 30a having a thickness equal to the original plate 50 on one side and groove portions 30b on both upper and lower sides thereof. 50, the peripheral end surface 50a and the end surface of the fitting portion 30a of the edge protector original plate 30 are joined to each other by the thermoforming molds 10 and 10 having the concave fitting portions 10a at positions corresponding to the edge protector raw material 30. What is necessary is just to heat press. At this time, in order to form an opening in the bath lid 2, the thermoforming molds 10, 10 are provided with protrusions 20, 20 whose total length matches the thickness of the opening 7. As a result, as shown in FIG. 4, the original plate 50 and the raw material 30 for the edge protector are compressed and firmly integrated with the face plates 8 and 8 as the core member 6 and the edge protector 11, and the edge protector 11 is removed from the lid body 12. A required rounded outer shape having a lip portion 11 b with a large thickness is formed, and a melted skin layer 14 is formed on the surface of the edge protector 11.

  On the other hand, when manufacturing the bath lid 4, the manufacturing method of the core material 6, the face material 8, and the edge protector 11 is the same as that of the bath lid 2, but the bath lid 4 does not have the opening 7. The heating mold 10 is not provided with a protrusion 20. Since the packing 13 uses the same material as the edge protector 11, the molding die 10 is provided with a recess capable of forming the shape of the packing 13, and can be molded simultaneously with the edge protector 11. The packing 13 can be bonded to the edge protector 11 with an adhesive.
