Description

  The present invention relates to a toilet seat device.

  Conventionally, it is known that a toilet seat is provided with a toilet lid, and the toilet lid is closed while the toilet seat device is not used, thereby preventing the spread of odor and improving the aesthetic appearance. . However, for example, in a toilet seat device used by a person who needs care, a backrest, a handrail, or the like may be arranged around the toilet seat. In such a case, the toilet lid is removed.

  In the case of using the toilet seat with the toilet lid attached thereto, when the toilet seat is opened, the toilet seat comes into contact with the toilet lid, and the rotation range of the toilet seat is restricted to a predetermined range. However, when the toilet seat device is used without attaching the toilet lid, the place where the rotation is restricted by the toilet lid disappears, and the toilet seat falls backward. Therefore, in order to regulate the rotation range of the hinge part of the toilet seat, the toilet seat includes a toilet seat regulating member that regulates the rotation of the toilet seat that can be disposed in the space around the hinge part of the toilet lid when the toilet lid is removed. An apparatus has been proposed (see, for example, Patent Document 1).

Japanese Patent No. 3815549

  By the way, the hinge part of the toilet lid has a hinge shaft part for rotating the toilet lid. However, since the hinge shaft part has a damper mechanism etc. for slowly closing the toilet lid, only the hinge shaft part is rotated. A very strong force was needed to make it happen. For this reason, when attaching the toilet seat restricting member, a special tool such as a sheet metal is required to rotate the hinge shaft, and this tool is housed inside the toilet seat restricting member. The toilet seat restricting member has a shaft attachment portion that accommodates the hinge shaft portion therein, and is disposed so as to fit on a predetermined curved surface behind the toilet body in a state where the hinge shaft portion is attached to the shaft attachment portion. . For this reason, the positional relationship between the toilet seat restricting member and the hinge shaft portion is extremely limited, and it is not easy to rotate and align the rigid hinge shaft portion to this limited position and attach the toilet seat restricting member. .

  An object of this invention is to provide the toilet seat apparatus which can attach a toilet seat control member easily.

  In order to achieve the above object, the present invention provides a toilet seat device (for example, a toilet seat device 1 described later) attached to a toilet body (for example, a toilet body 2 described later), and a functional unit disposed at the rear of the toilet body. A cover portion (for example, a cover portion 5 described later), a toilet seat (for example, a toilet seat 3 described later) rotatably attached to the cover portion, and a toilet lid provided on the cover portion so that the toilet lid can be rotated. A hinge shaft portion that can be attached (for example, a hinge shaft portion 51 described later) and a hinge shaft portion that is attached to the cover portion so as to cover the hinge shaft portion in a state in which the toilet lid is removed, and restricts a rotation range of the toilet seat. A toilet seat restricting member (for example, a toilet seat restricting member 4 to be described later), and the toilet seat restricting member includes a fitting portion (eg, a fitting portion that can be fitted to the hinge shaft portion in order to rotate the hinge shaft portion). The fitting part 40) described later is To provide a toilet seat device to be made.

  The fitting portion is preferably disposed at a position where the shaft mounting portion of the toilet seat regulating member is not visible from the outside in a state where the shaft mounting portion is attached to the hinge shaft portion.

  The fitting portion is preferably formed at a position where the toilet seat restricting member is rotatable about the hinge shaft portion in a state where the fitting portion is fitted to the hinge shaft portion.

  The fitting portion 40 is a through hole formed in the rear surface portion 41. The shape of the fitting portion 40 is adapted to the shape of the end portion of the hinge shaft portion 51 so that the end portion of the hinge shaft portion 51 can be fitted into the fitting portion 40. The fitting portion 40 is disposed at a position where the toilet seat regulating member 4 can be rotated around the hinge shaft portion 51 in a state where the fitting portion 40 is fitted to the hinge shaft portion 51.

FIG. 5 is a view showing a state in which the hinge shaft portion is aligned using the toilet seat regulating member 4. With reference to FIG. 5, the procedure of use of the toilet seat restricting member 4 will be described.
Assume that the toilet seat apparatus 1 is used with a toilet lid (not shown) attached, for example. In this case, a hinge part of the toilet lid is coupled to the hinge shaft part 51 so as to open and close the toilet lid. Here, when it becomes necessary to attach a backrest or a handrail, the toilet lid is removed. When the toilet lid is removed, a space from the rear end of the toilet seat hinge portion 32 of the toilet seat 3 to the back surface portion 52c in the concave portion 52 of the cover portion 5 is vacated as shown in FIG. In this state, when the toilet seat 3 is opened, the toilet seat hinge portion 32 rotates and the toilet seat 3 falls to the rear side. Therefore, it is desirable to dispose the toilet seat regulating member 4.

  The toilet seat restricting member 4 is adapted so that its outer shape fits into the recess 52 of the cover portion 5, but on the other hand, it is necessary to match the position of the hinge shaft portion 51 that has rotated the toilet lid. Therefore, as shown in FIG. 5, the fitting portion 40 formed on the rear surface portion 41 of the toilet seat regulating member 4 is fitted to the hinge shaft portion 51, and the toilet seat regulating member 4 is gripped and rotated like a handle. The direction of the end portion of the hinge shaft portion 51 is aligned. For example, when the side surface portion 43 of the toilet seat regulating member 4 is rotated so as to be horizontal with the upper surface of the toilet seat hinge portion 32 and the upper surface of the cover portion 5, the end portion of the hinge shaft portion 51 is aligned at an appropriate position.

Rotate. For this reason, it is not necessary to prepare a special tool separately and store it inside the toilet seat restricting member 4, and the toilet seat restricting member 4 can be used as a tool and installed as the toilet seat restricting member 4. Since it is not necessary to secure a space for storing the tool in the toilet seat regulating member 4, the degree of freedom in designing the toilet seat regulating member 4 is improved. Further, if the position of the hinge shaft portion 51 in a state where the toilet seat restricting member 4 is appropriately disposed on the cover portion 5 is determined in advance, the hinge shaft portion 51 is fitted to the fitting portion 40 of the toilet seat restricting member 4. In this state, it is also determined to which position the toilet seat regulating member 4 is tilted, so that positioning becomes easy. Therefore, the toilet seat restricting member 4 can be easily attached.

  Moreover, according to this embodiment, the fitting part 40 was arrange | positioned in the position which is not visually recognized from the outer side in the state in which the shaft attaching part 47 of the toilet seat control member 4 was attached to the hinge shaft part 51. Thereby, the toilet seat restricting member 4 is disposed in the recess 52 of the toilet seat 3, and when the toilet seat restricting member 4 is viewed from the outside, the fitting portion 40 provided in the toilet seat restricting member 4 is not visually recognized from the outside. The toilet seat regulating member 4 can be easily attached while improving.

  Further, according to the present embodiment, the fitting portion 40 is formed at a position where the toilet seat restricting member 4 can rotate around the hinge shaft portion 51 in a state where the fitting portion 40 is fitted to the hinge shaft portion 51. Thereby, since the hinge axial part 51 can be reliably rotated by rotating the toilet seat control member 4, the effect similar to the above can be show | played.

It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.
