Description

  The present invention relates to a bath lid. More specifically, the present invention relates to the structure of a bath lid that is applied in contact with the inner surface of a bathtub.

Usually, a bath lid applied to a unit bath or the like in a general household is used by placing a wound lid, a combined lid or the like on a flange surface provided around the bathtub.
JP 10-117957 A (page 1-4, FIG. 1)

  However, when a hot water mixing tap is provided as a deck faucet at a specific location on the flange surface of the bathtub, for example, at the corner of the flange surface, a notch is formed in the winding lid, the assembly lid or the like so as to avoid the deck faucet. It is necessary to provide or change the shape. As described above, it is troublesome to cut out a part of the wound lid, the assembled lid, etc., and it is inferior in production efficiency and advantageous in cost to produce bath lids of various shapes according to the type of bathtub. That's not true. The present invention solves such problems and provides a bath lid that can be applied to various types of bathtubs, such as a bathtub equipped with a deck faucet, and that is excellent in heat insulation and heat insulation and can be easily attached and detached. Is the issue.

  In order to solve the above problems, the present invention takes the following technical means. That is, according to the present invention, a bath lid is applied in contact with the inner surface of the bathtub, and the bath lid includes a lid main body and a holding portion that is continuously provided around the lid body and in contact with the inner surface of the bathtub. The lid body is formed of a heat insulator, and the holding portion is provided with a bath lid formed of a soft material.

  As the heat insulator, a heat insulating material, for example, a synthetic resin foam such as foamed polyethylene or foamed polyurethane foam, a sponge, or a heat insulating sheet in which an air layer is encapsulated between two water-resistant sheets can be used. . Among them, it is preferable to use a heat insulating sheet, and a heat insulating sheet in which an aluminum vapor-deposited sheet in which metal aluminum is vapor-deposited on a plastic sheet such as PET is used for the upper and lower layers, and an air layer is included between the two layers is preferably used. Further, the air layer in the heat insulating sheet may be simply included in a sandwich shape, or the upper and lower two aluminum vapor deposition sheets may be divided into a large number of cells, and the air layer may be composed of a large number of air chambers. Good.

  It is preferable that a wire is embedded around the heat insulator. The wire is not particularly limited, such as a metal or a hard plastic, but is preferably formed of a metal, particularly a shape memory alloy.

  The bath lid according to the first aspect of the present invention includes a lid main body and a holding portion that is connected to the lid main body and is in contact with the inner surface of the bathtub. The lid main body is formed of a heat insulator, and the holding portion is Since it is formed of a soft material, it can be easily fitted in the bathtub and can be covered with good heat retention and heat insulation. Moreover, since the bathtub is usually tapered so as to narrow downward from the flange surface, it can be easily attached and detached.

  Since the heat insulator is a heat insulating sheet including an air layer between two upper and lower aluminum vapor-deposited sheets, it is lightweight and excellent in heat insulating effect, and is covered with good heat retention while preventing a drop in hot water temperature. Can do.

  Since the wire is embedded around the heat insulator, a contour that follows the shape of the bathtub can be formed, and the lid body can be pressed against the inner wall of the bathtub by the tension of the wire. Further, by forming the wire from a shape memory alloy, it can be folded and stored without taking up space, and since it returns to its original shape when used, it can be easily covered.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side sectional view showing a schematic configuration of a bath lid A according to the present invention, and FIG. 2 is a side sectional view showing a main part of the bath lid A of FIG. As can be clearly understood from FIGS. 1 and 2, the bath lid A is covered with the inner surface of the bathtub 4, and is continuously provided around the heat insulator 1 and the heat insulator 1 as a lid body. And holding part 2 in contact with the inner surface. The heat insulating sheet as the heat insulator 1 includes an air layer 13 between two aluminum vapor deposited sheets, an upper aluminum vapor deposited sheet 11 and a lower aluminum vapor deposited sheet 12. Moreover, the holding | maintenance part 2 is formed in a tongue piece shape so that contact property with the inner surface of the bathtub 4 may become favorable while it consists of soft rubber.

  As well shown in FIG. 2, a wire 3 made of a shape memory alloy is embedded around the heat insulator 1, and the heat insulator 1 follows the shape of the bathtub 4 to form a contour. Cover the lid body against the inner wall of the bathtub. Moreover, when it is removed, it can be folded and stored without taking up any space, and can be easily restored to its original shape when covered.

  FIG. 3 is a perspective view showing a state where the bath lid A according to the present invention is applied to the bathtub 4. Although not shown in FIG. 3, handles of various shapes such as a ring shape and a string shape may be attached to facilitate attachment to and removal from the bathtub 4, and the upper aluminum vapor deposition sheet 11 and the lower portion may be attached. The space between the aluminum vapor deposition sheet 12 may be divided into a large number of cells, and the air layer may be composed of a large number of air chambers. As described above, the design of the bath lid A according to the present invention can be variously changed, and all belong to the technical scope of the present invention.

It is side sectional drawing which shows schematic structure of the bath lid concerning this invention. It is a sectional side view which shows the principal part of the bath lid shown in FIG. It is a perspective view which shows the state which applied the bath lid concerning this invention to the bathtub.
