Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a structure for attaching a synthetic resin toilet lid to a synthetic resin toilet seat.

[Background Art] Conventionally, when attaching a synthetic resin toilet lid to a synthetic resin toilet seat, a synthetic resin shaft or a metal shaft was used. The shaft is weak in strength, and the metal toilet seat and toilet lid are made of synthetic resin, which gives a strange feeling and is undesirable in terms of appearance. In addition, when attaching the toilet lid to the toilet seat with a shaft, as shown in FIG. The shaft 9 is inserted between the shaft hole 10 of the toilet seat side bearing projection 2 and the shaft hole 11 of the toilet lid side bearing projection 5, which are in communication with each other, and the shaft support portion and the stopper projection are provided in a protruding manner. By positioning the head 6 of the shaft 9 between the shaft 9 and the stopper projection 3, and slightly positioning the end of the stopper protrusion 3 within an area surrounded by an extension of the outer periphery of the head 6 of the shaft 9,
The inventor of the present invention thought that the shaft 9 could be easily installed by preventing the shaft 9 from coming off, but in this case, when the shaft 9 is inserted, if the shaft 9 is made of metal, the head of the shaft 9 6 may hit the stopper protrusion 3 and damage the synthetic resin stopper protrusion 3. For this reason, if the shaft 9 is made of metal, a stopper protrusion 3 is provided to prevent it from coming off. This means that the structure cannot be adopted.

[Purpose of the invention] This invention was devised in view of the above points, and its purpose is that since the surface is made of synthetic resin, it cannot be used with synthetic resin toilet seats or synthetic resin toilet lids. In addition, by using a metal shaft as the core, it is strong and requires a smaller diameter than a synthetic resin shaft, and the stopper protrusion is not damaged when inserting the shaft. To provide a structure for attaching a toilet lid to a toilet seat, which prevents the toilet lid from being damaged.

[Disclosure of the invention] The structure for attaching a toilet lid to a toilet seat of the present invention includes a toilet seat 1 made of synthetic resin, a toilet seat side bearing protrusion 2 and a stopper protrusion 3 protruding from the toilet seat 1, and a toilet lid 4 made of synthetic resin. A toilet lid side bearing protrusion 5 is provided protrudingly provided on the toilet lid side bearing, and the outer circumference of a metal shaft body 7 having a head 6 is coated with a synthetic resin layer 8 to constitute a shaft 9, and the toilet seat side bearings communicate with each other. The shaft hole 10 of the protrusion 2 and the shaft hole 11 of the toilet lid side bearing protrusion 5
Insert the shaft 9 and position the head of the shaft 9 between the shaft support portion and the stopper protrusion 3,
The end of the stopper protrusion 3 is slightly located within an area surrounded by an extension of the outer periphery of the head 6 of the shaft 9 covered with synthetic resin, and such a configuration is adopted. Thus, the above-mentioned purpose of the present invention has been achieved. That is, in the present invention, the outer circumference of a metal shaft 7 having a head 6 is covered with a synthetic resin layer 8 to form a shaft 9, so that the external appearance is made of synthetic resin. It does not look out of place with the synthetic resin toilet seat 1 or the synthetic resin toilet lid 4, and since the metal shaft serves as the core, it is strong and can be made small in diameter. When the shaft 9 is inserted, the synthetic resin layer 8 comes into contact with the stopper protrusion 3, and when the head 6 of the shaft 9 passes over the stopper protrusion 3, the synthetic resin layer 8 covering the head 6 becomes elastic. This prevents the stopper protrusion 3 from being damaged due to deformation.

The present invention will be explained in detail below with reference to Examples. The toilet seat 1 is made of synthetic resin, and has protrusions 2 for bearings on the toilet seat side projecting from both ends of the rear part of the toilet seat 1. A shaft hole 10 is bored in this toilet seat side bearing protrusion 2.
Further, a stop protrusion 3 is provided on the inner side of the toilet seat side bearing protrusion 2 at both ends of the rear portion of the toilet seat 1 at a distance from the toilet seat side bearing protrusion 2. Further, the toilet lid 4 is made of synthetic resin, and a toilet lid side bearing protrusion 5 is provided protruding from the rear end of the toilet lid 4. A shaft hole 11 is bored in the toilet lid side bearing protrusion 5.
The shaft 9 is constructed by covering the outer periphery of a metal shaft body 7 having a head 6 with a synthetic resin layer 8 such as polyamide resin. To cover the outer circumference of the shaft body 7 with the synthetic resin layer 8, for example, the outer circumference of the metal shaft body 7 is coated with synthetic resin. However, the third
As shown in the figure, the shaft hole 10 of the toilet seat side bearing protrusion 2
and the shaft hole 11 of the toilet lid side bearing protrusion 5 are in communication with each other, insert 9 and pivotally support the toilet seat side bearing protrusion 2 and the toilet lid side bearing protrusion 5 with the shaft 9. It is something. In this case, the head 6 of the shaft 9 is positioned between the shaft support portion and the stopper protrusion 3, and an area surrounded by an extension of the outer periphery of the head 6 of the shaft 9 coated with synthetic resin. The end of the stopper protrusion 3 is positioned slightly inside, so that even if the shaft 9 tries to come out, the head 6 of the shaft 9 will come into contact with the stopper protrusion 3 and the shaft 9 will not come out. ing. When the shaft 9 is supported in this way, the head 6 of the shaft 9 hits the stopper protrusion 3 and cannot be removed, so when inserting the shaft 9 (that is, when inserting the shaft 9 in the direction of the arrow in FIG. ), the head 6 of the shaft 9 hits the end of the stopper projection 3 made of synthetic resin, but since the synthetic resin layer 8 on the outer periphery of the head 6 of the shaft 9 hits the stopper projection 3, the elasticity of the synthetic resin layer 8 As a result, the head 6 can be inserted over the stopper protrusion 3 without damaging the stopper protrusion 3. In this way, in the present invention, the shaft can be supported simply by inserting the shaft 9. The toilet seat 1 with the toilet lid 4 pivoted as described above is constructed by inserting the tip of the shaft 9 into the shaft hole 13 of the mounting bearing member 12, and attaching the mounting bearing member 12 to the rear of the toilet bowl. In this case, a bolt 15 is suspended from the lower part of the mounting bearing member 12, and this bolt 15 is attached to the hot water cleaning device 1.
It is installed by inserting it into a mounting hole provided at the rear of the toilet bowl through the base part 4.

[Effects of the invention] As described above, the shaft of the present invention is constructed by covering the outer periphery of a metal shaft body with a head with a synthetic resin layer, so that the appearance of the shaft is that of a synthetic resin. , it does not look out of place with synthetic resin toilet seats and synthetic resin toilet lids, and has a better appearance.Also, the metal shaft serves as the core, which makes it strong and allows for smaller diameters. Moreover, when the shaft is inserted, the synthetic resin layer comes into contact with the stopper projection, and when the shaft head crosses the stopper projection, the synthetic resin layer covering the head is elastically deformed. This prevents damage to the stopper protrusion.
