FIG. 1 is a perspective view showing a state in which a top opening of a bathtub C is covered with a bathtub cover A of the present invention.
Heretofore, bathtub lids have been made of wood or have been provided with a foldable bathtub lid made of synthetic resin. The flat-plate-like bathtub lid A of the present invention has an improved degree of sealing between the bathtub C and the edge protector B provided therearound. The reinforcing core material 3 interposed in the above is made of a heat insulating material or the like, and is used for improving the heat insulating property of the bathtub C.

In the conventional bathtub lid A, FIG.
As shown in the figure, a reinforcing core material 3 made of a synthetic resin material such as styrene foam is interposed as a plate over the entire surface between the upper face material 1 and the lower face material 2. As described above, when the plate-shaped reinforcing core 3 is interposed between the upper surface material 1 and the lower surface material 2 over the entire surface, the bathtub cover A
, The material cost of the reinforcing core material 3 was increased, and the heat retention performance was also reduced.

On the other hand, in the present invention, as shown in FIGS. 2, 3 and 4, the reinforcing core material is not partially provided between the upper face material 1 and the lower face material 2 but is partially provided. 3 and the other parts are hollow, improving the heat retention performance and reducing the weight.
This is to reduce costs. In the case of FIG. 2, the reinforcing core material 3 is arranged only at the peripheral portion where the upper surface material 1 and the lower surface material 2 are overlapped with each other at the position of the outer periphery of the square shape. And, the reinforcing core material 3 is not arranged at the center of the plane of the bathtub lid A.

In the embodiment shown in FIG. 3, the reinforcing core material 3 is formed by crossing in a cross shape.
Thus, the upper surface material 1 and the lower surface material 2 are joined together. Also, in the embodiment of FIG.

B is also formed in the shape of a “concave”, so that the upper and lower edges are merely fitted together along the outer surfaces of the upper panel 1 and the lower panel 2. Therefore, if the adhesion was weak, it was easy to come off. In the present invention, the edge protector B is formed in a cross-sectional view in the shape of a “mountain”, and the central projection 15 at the center of the “mountain” is formed by the upper face material 1 and the lower face material 2.
The edge protector B is less likely to come off because it is fitted and fixed in the recessed space 4 between the two.

The shape of the edge protector B shown in FIG. 6 is the same as that of FIG. 6. Then, the fitting protrusion 5 fitted into the fitting concave portion 6 protrudes from the reinforcing core material 3. As described above, the fitting protrusion 5 protruding from the reinforcing core material 3
And the engaging concave portion 6 provided in the central projection 15, a locking force acts. Therefore, the holding force of the edge protector B bonded with an adhesive can be used together to increase the holding force of the edge protector B. It works.

In the embodiment of the edge protector B shown in FIG. 7, a large fitting concave portion 6 is formed inside the edge protector B, and the fitting concave portion 6 is formed in an arrow shape, and a shape corresponding to the arrow is formed. Are projected from the reinforcing core material 3. As described above, by making the fitting projection 5 large and the fitting recess 6 so as to have the full cross section of the edge protector B, the holding force of the edge protector B can be further increased.

FIG. 8 shows an embodiment in which the reinforcing core member 3 and the fitting projection 5 are formed separately. The point that the tip on the side of the fitting protrusion 5 is formed in the shape of an arrow and the point that the fitting recess 6 is provided on the side of the edge protector B are the same as in the embodiments of FIGS. 6 and 7. In the embodiment shown in FIGS. 9 and 10, an edge protector B made of a synthetic resin, rubber, or the like is configured to be openable and closable at a hinge portion 9, and is provided on one of the upper and lower divided edge protectors B. In order to exert a holding force, the fitting projection 7 and the fitting recess 8 are engaged in a state where the fitting projection 7 is provided with the fitting recess 8 on the other side and the upper face material 1 and the lower face material 2 are sandwiched. Make up.

As described above, the present invention has the following advantages. 2. An edge protector comprising a bathtub lid comprising a combination of an upper surface material, a lower surface material, and a reinforcing core material partially interposed between the two surface materials, and attached to a peripheral edge of the bathtub lid. Has three protrusions in the shape of a cross-section “mountain”, with a shape protruding inward.
The central projection of the three U-shaped projections, between the upper and lower face materials,
Fitted into the concave space formed outside the reinforcing core material, it can be hollowed between the upper surface material and the lower surface material, reducing the weight of the bathtub lid, improving heat insulation performance, and improving heat insulation performance. Improvement can be achieved. In addition, warpage due to a change in temperature of the entire bathtub lid is less likely to occur. Also, "Mountain"
Since the central protruding portion having a U-shape is fitted in the recessed space between the upper face material and the lower face material, the force for holding the edge protector is strong, and it is difficult for the edge protector to come off.

According to a second aspect of the present invention, the bathtub lid is composed of an upper face material, a lower face material, and a reinforcing core material interposed between the two face materials, and the core material is provided on both sides in the peripheral direction of the bathtub lid. The fitting protrusion protruding from the material is protruded, and a fitting recess fitted to the fitting protrusion is formed on the side of the bathtub lid of the edge protector attached to the periphery of the bathtub lid. Since only the fitting concave portion generates a force for holding the edge protector, there is no need to attach an adhesive, and in such a case, the edge protector can be easily attached and detached, and the edge protector can be replaced. It is. In addition, in addition to the holding force of the fitting projection and the fitting recess, when the bonding is performed by the adhesive, a stronger holding force of the edge protector can be exhibited. This makes it difficult for the edge protector to come off.

According to a third aspect of the present invention, the edge protector attached to the periphery of the bathtub lid is provided with a hinge portion which can be divided and opened up and down with a plane of the bathtub lid as a boundary, and a joint surface of the edge protector divided at the upper portion. In addition, since the fitting projection and the fitting recess which are integrally connected with the bathtub lid held therebetween are provided on either of the upper divided bodies, the edge protector is formed by the locking force of only the fitting projection and the fitting recess. In the case of holding, the edge protector in the bathtub lid is easily assembled and disassembled. Also, since the hinge part can be opened around the center, the conventional rubber cord-shaped edge protector is pulled and stretched as in the case of fitting around the bathtub lid, and then the upper face material, the lower face material, and the reinforcing core It is possible to assemble it without extending it, instead of fitting it to the material, with the length of a normal edge protector, so there is no thinner part of the edge protector at the corner of the bathtub lid . As a result, when the bathtub lid is raised and lowered, the possibility that the corner is damaged and broken is reduced.
