Abstract

PROBLEM TO BE SOLVED: To provide an attaching structure for bathtub apron made of thermoplastic resins. SOLUTION: A pedestal 41 of ABS resin foam is fixed to the upper part of a bathtub apron 4 made of ABS resins by adhesion, and an engaging tool 42 is attached to the pedestal 41 by a vis 41a. Besides, an engaging tool 44 made of ABS resins is fixed to the lower part of the bathtub apron by adhesion. Since the pedestal 41 and the engaging tool 44 are formed from the same thermoplastic resins as the bathtub apron 4, they can be attached to the bathtub apron 4 by adhesion or thermal melt-sticking. By engaging the engaging tools 42 and 44 to holders 43 and 45 attached to a side wall 5, the bathtub apron 4 can be easily and strongly attached to the side wall 5.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a bathtub apron which is detachably mounted on a side wall of a washing unit of a bathroom unit which is provided upright from a bathtub side end.

[0002]

2. Description of the Related Art Conventionally, as a mounting structure of a bathtub apron,
Japanese Unexamined Patent Publication No. Hei 9-327410 describes an arrangement in which a bathtub apron is detachably attached to a side wall by a receiving member provided on a side wall and an engagement member provided on a bathtub apron.

[0003]

However, in the case of the mounting structure of the bathtub apron described in Japanese Patent Application Laid-Open No. 9-327410, there are the following problems.

[0004] First, the receiving member and the engaging member are fixed to the side wall and the bathtub apron by screws. No special design considerations are required as the side walls are covered with a bathtub apron. However, the bathtub apron will be directly seen by the person using the bathroom, so design considerations are required.

[0005] Therefore, it is necessary to make the screw for attaching the engaging tool to the bathtub apron shorter than the thickness of the bathtub apron. However, in order to secure the required mounting strength, it is necessary to increase the thickness of the bathtub apron by a certain amount or more, resulting in a problem that the cost is increased.

In order to solve the above-mentioned problems, a bathtub apron is formed of FRP, a fixing plate is provided on an engaging member, and uncured FRP is laminated and cured over the fixing plate and the bathtub apron. An engagement tool can also be attached.

However, in this method, the material of the bathtub apron is limited to FRP, and the material cost is lower than FRP.
There is a problem that a thermoplastic resin with good production efficiency cannot be adopted.

The present invention has been made in view of the above problems, and has as its object to provide a mounting structure for a bathtub apron made of a thermoplastic resin.

The engaging tool is provided with a fixing portion, and the fixing portion is formed of the same type of thermoplastic resin as the bathtub apron.

According to a second aspect of the present invention, there is provided a bathroom unit having a washing place, a bathtub, and a bathtub apron, wherein a side wall of the washing stand, which is provided upright from a bathtub side end of the washing place, has a receiving member provided on the side wall. A mounting structure for the bathtub apron, in which the bathtub apron is detachably mounted by an engaging tool provided on the bathtub apron, wherein the bathtub apron is made of a thermoplastic resin, and has the same heat as the bathtub apron. A pedestal made of a plastic resin is provided on the bathtub apron, and the engaging tool is attached to the pedestal.

According to a third aspect of the present invention, there is provided a bathroom unit having a washing place, a bathtub, and a bathtub apron, wherein a side wall of the washing place standing upright from a bathtub side end of the washing place is provided with a receiving member provided on the side wall. A mounting structure of the bathtub apron, wherein the bathtub apron is detachably mounted by an engagement tool provided on the bathtub apron, wherein the bathtub apron is made of a thermoplastic resin, and the engagement tool is locked. The fixing piece is attached to the bathtub apron by a holding tool formed of the same kind of thermoplastic resin as the bathtub apron.

The techniques of the present invention may be used in combination with each other. For example, the upper engagement tool of the bathtub apron is attached to a pedestal formed of the same type of thermoplastic resin of the bathtub apron, and the fixing portion of the lower engagement tool is formed of the same type of thermoplastic resin as the bathtub apron. Is also good.

[0013] The thermoplastic resin in the present invention is not particularly limited, but an ABS resin, a polyolefin resin, an acrylic resin, a polycarbonate resin or the like having good moldability can be used.

[0014]

In the bathtub apron mounting structure according to the first aspect of the present invention, the bathtub apron is made of a thermoplastic resin, and a fixing portion is provided on the engaging member, and the fixing portion is made of the same type of thermoplastic as the bathtub apron. It is made of resin. Therefore, by firmly fixing the fixing portion to the bathtub apron by adhesion or heat fusion, it is possible to attach the engaging tool.

Further, in the mounting structure of the bathtub apron according to the second aspect of the invention, the bathtub apron is made of a thermoplastic resin, and a pedestal made of the same type of thermoplastic resin as the bathtub apron is attached to the bathtub apron. And an engaging member is attached to the pedestal. Therefore, if the pedestal is fixed to the bathtub apron in advance by bonding, heat fusion, or integral molding, the engaging member can be attached with screws regardless of the material.

According to a third aspect of the present invention, in the bathtub apron mounting structure, the bathtub apron is made of a thermoplastic resin, the engaging member has a locking piece, and the same thermoplastic resin as the bathtub apron. The locking piece is attached to the bathtub apron by means of a holding tool formed from. Therefore,
Regardless of the material of the engagement tool, the engagement tool can be attached to the bathtub apron via the locking piece by fixing the holding tool to the bathtub apron by bonding or heat fusion.
