Description

[Detailed description of the invention] The present invention relates to the improvement of combination lids that are used in combination, such as a set of two or a set of three, and in particular, the bathtub lid is divided into a main unit and a secondary unit. This bathtub lid is divided into two parts, a plurality of sub-units having different lengths in the width direction are prepared, and the sub-unit can be appropriately selected according to the size of the bathtub to be used.

In the case of a combination lid, the length in the longitudinal direction as well as the length in the width direction are predetermined, so depending on the size of the bathtub, the lid may be small and a gap may be created on the top of the bathtub. Another disadvantage is that the lid is too large and protrudes outward from the top of the bathtub, making it difficult to use.

The purpose of the present invention is to eliminate the disadvantages of such conventional combination lids, to divide all or part of the bathtub lid that constitutes the lid into two into a main unit and a secondary unit, and to reduce the length in the width direction. Prepare a plurality of secondary units with different lengths in the width direction for the main unit with a constant width, and select the secondary unit appropriately according to the size of the top surface of the bathtub to be used, and then create a bathtub lid unit. To provide a bathtub lid whose length in the width direction is variable.

EMBODIMENT OF THE INVENTION Hereinafter, the specific structure of this invention is demonstrated in detail based on the illustrated Example.

The present invention relates to a bathtub lid that is used as a set of a plurality of lids.
The whole or a part of is divided into a main unit 2 and a secondary unit 3, and a pair of engagement means 4 and 5 are provided on at least one side in the longitudinal direction of the main unit 2 and the secondary unit 3, respectively. Therefore, for the main unit 2 whose length in the width direction is constant, a plurality of secondary units 3 having different lengths in the width direction are prepared, and the secondary unit 3 is adjusted according to the size of the top surface of the bathtub to be used. The structure is such that the main unit 2 and the secondary unit 3 are engaged with each other by the engaging means 4 and 5 to be integrated by selecting an appropriate unit.

FIG. 1 shows an example of the bathtub lid of the present invention made of synthetic resin manufactured by extrusion molding, and 1 in the figure indicates the bathtub lid alone. The units 1 are used in combination, such as in sets of two or sets of three, and placed side by side on the top of the bathtub, but the present invention combines all or part of the unit lid 1 with the main unit 2. It is constructed by a barrel unit 3.

The main unit 2 is provided with one or more reinforcing ribs 6 that connect the front surface and the back surface as necessary, and the length in the width direction thereof is constant. The length in the longitudinal direction of the secondary unit 3 is the same as the length in the longitudinal direction of the main unit 2, but the length in the width direction is
As shown in FIG. 2, a plurality of different types are prepared.

At least one side of the main unit 2 and the secondary unit 3 in the longitudinal direction has a pair of engagement means 4, 5, respectively.
In the illustrated embodiment, the engaging means 4 provided on the main unit 2 is a groove or a dovetail groove, and the engaging means 5 provided on one longitudinal side of the secondary unit 3 is provided. is a protrusion or dovetail, and by fitting the protrusion or dovetail into a groove or a dovetail groove formed on one side in the longitudinal direction of the main unit 2, both units 2 can be separated. , 3 are in an engaged state. In addition, when the main unit 2 and the secondary unit 3 are engaged with each other by the engaging means 4 and 5, and the cap 7 is tightly attached to both ends, it is possible to prevent the two units 2 and 3 from separating. It is.
(Figure 1). Furthermore, if the cap 7 is made of soft vinyl chloride or the like containing a large amount of plasticizer, the frictional resistance against the upper surface of the bathtub will increase, which will help prevent slipping.

Although the illustrated embodiment shows an extrusion-molded bathtub lid, the present invention is not limited to this, and the main unit 2 and the secondary unit 3 can be formed by other molding methods, such as injection molding. It can also be molded.

Also, it is not necessary to divide all of the bathtub lid units 1 into two; for example, in the case of a set of three lids, only one lid is divided into two, the main unit 2 and the secondary unit 3, and the other two remain as they are. It is also possible to leave it in this state.

In the case of the bathtub lid of the present invention, the secondary units 3 having different lengths in the width direction are selected, connected to the main unit 2, and made large enough to substantially cover the top surface of the bathtub. This eliminates the drawbacks of the conventional method, such as a gap on the top surface of the bathtub and heat dissipation from there, and the drawback that the lid protrudes from the top surface of the bathtub, making it difficult to handle. Additionally, in the past, it was necessary to prepare multiple types of molds for manufacturing bathtub lids depending on the size of the bathtub, but with the present invention, only one mold is needed for the main unit. It is now possible to prepare only a few types of single-piece molds that are short in width direction and can be produced at a relatively low cost, reducing the cost required for molds and making inventory management much easier than before. becomes easier. Furthermore, you can enjoy color coordination by using different colors for the main and secondary units.
