Abstract

PROBLEM TO BE SOLVED: To prevent a soft closing unit from being damaged by forming an overspeed preventing stopper between a toilet lid and a hinge support in a toilet lid device having a hinge support mounting and fitting the soft closing unit for gently closing the toilet lid and a main body. SOLUTION: A main body part 1 incorporating a nozzle for washing the private parts is constituted of a case cover 1-a and a case plate 1-b. In a toilet lid 2 and a toilet seat 3, a soft closing unit 5 is mounted on a hinge part and is inserted into a groove for coupling of the case cover 1-a via a hinge support 4 into which an output shaft 5-a is fitted. In this case, a toilet lid stopper 2-a is formed on the toilet lid 2 and the hinge support 4 is provided with a support stopper 4-a. When load is applied to the toilet lid 2 from the upper side, overspeed when the soft closing unit 5 is going to revolve is prevented by these stoppers 2-a, 4-a and an overspeed preventing structure within the soft closing unit 5 is prevented from being broken.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warm water flush toilet seat having a soft closing function on a toilet lid, whereby over rotation and overload can be applied to a unit having a soft closing function by being deformed with respect to a load from above. The soft closing unit is broken, especially in a sanitary washer having a stool lid that is easily deformed by a load from above in terms of shape and material due to the fitting stopper structure against the load. The present invention relates to a structure for preventing an excessive rotation of a hinge portion for preventing the rotation.

[0002]

2. Description of the Related Art Conventionally, Japanese Utility Model Laid-Open No. 05-082396,
5-082398, 06-058796, and
As disclosed in Japanese Patent Application Laid-Open No. 06-077694, as a method for realizing a toilet seat / toilet lid attaching / detaching structure which gives a soft closing function to the toilet seat / toilet lid while considering the cleaning property,
A hinge support structure has been proposed in which a shaft portion of a soft closing unit that is respectively coupled to a toilet lid is fixed and the portion is fitted to a main body.

As a method of resisting the load when the hinge support is seated, as disclosed in Japanese Utility Model Laid-Open No. 06-079396, a method of receiving the load with a case cover and preventing both the toilet seat and the lid from coming off can be used. Proposed.

[0004]

In the conventional hinge support structure, it is possible to prevent the hinge support structure from coming off against the load when sitting on the toilet seat. However, considering a case in which a load is applied from above the toilet lid and the toilet lid itself is deformed, the soft closing unit is fitted to the toilet lid itself and rotates with the deformation. Depending on the magnitude of the load from above the toilet lid, the soft closing unit itself may be over-rotated beyond the rotation stopper position, and the soft closing unit may be damaged.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a soft closing unit that is capable of deforming a stool lid even when a load is applied to the lid. An object of the present invention is to provide a sanitary washing device in which the soft closing unit is not damaged even when the toilet lid is deformed without being rotated.

[0006]

To achieve the above object, the present invention provides a soft closing unit for loosely closing a toilet lid, and a hinge for fitting the soft closing unit to a main body. In a warm water flush toilet seat with a support, an over rotation prevention stopper is formed between the toilet lid and the hinge support so that the soft closing unit does not rotate more than expected, so that deformation of the toilet lid does not lead to rotation of the soft closing unit. There is no danger of the soft closing unit being damaged.

According to a second aspect of the present invention, the over-rotation prevention stopper is fitted tangentially to the rotation direction of the toilet lid rotation, so that the load in the rotation direction applied to the soft closing unit is efficiently stopped. be able to.

According to a third aspect of the present invention, the excessive rotation preventing stopper provided between the toilet lid and the hinge support sets a difference in strength,
When breaking, the hinge support side is assumed to break, so even if a load larger than expected occurs and breaks,
Maintenance is possible by replacing the relatively inexpensive hinge support.

According to a fourth aspect of the present invention, the over-rotation prevention stopper provided between the toilet lid and the hinge support is set at a position which cannot be directly visually confirmed from a facing human body, and a stopper structure provided on the toilet lid and the hinge support. Are easily seen from the external appearance and are not difficult to see.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of a sanitary washing apparatus incorporating the present invention. The main body 1 having a built-in local cleaning nozzle (not shown) includes a case cover 1-a that is located above the main body 1 and a case plate 1-b that is formed on the toilet surface.
It is constituted by. The toilet lid 2 and the toilet seat 3 each have a soft cover unit (not shown) for loosely closing the hinge cover, and a case cover 1-b via a hinge support 4 to which an output shaft (not shown) is fitted.
Is inserted into the coupling groove formed in the second groove.

FIG. 2 is a center sectional view of a sanitary washing apparatus incorporating the present invention. In the center of the hinge of the stool lid 2, a soft closing unit 5 for loosely closing the stool lid 2 is provided.
Are fitted. Output shaft 5 of the soft closing unit 5
“a” is inserted into the coupling groove formed in the case cover 1-b via the fitted hinge support 4.

FIG. 3 shows a case where a load is applied to the toilet lid from above. The soft closing unit 5 rotates in accordance with the deformation of the toilet lid. This rotation causes the soft closing unit 5 to rotate to a range larger than expected, and in the worst case, it is conceivable to break the over-rotation prevention structure provided inside.

FIG. 4 shows an embodiment of the present invention in which the toilet lid is closed. The toilet lid 2 is formed with a toilet lid stopper 2-a in a tangential direction of its rotation. Hinge support 4 fitted to output shaft 5-a of soft closing unit 5
Is provided with a support stopper 4-a which is also tangential to the rotation in order to generate a drag on the toilet lid stopper 2-a. When a load is applied to the toilet lid from above, the soft closing unit 5
Tries to rotate, but the over-rotation is
−a and the support stopper 4-a interfere with each other and are stopped. Therefore, the over-rotation prevention structure provided inside the soft closing unit 5 is not broken.

[0014] If a load exceeding the upper limit of the assumed load value applied from above to the toilet lid is applied, if the support side is broken first, even if damage occurs, In addition, it is only necessary to replace the hinge support 4, which is a small molded product, instead of the toilet lid 2, which is a large molded product, so that the user's financial burden can be reduced.

FIG. 5 shows a state in which the toilet lid of the embodiment shown in FIG. 4 is opened. The support stopper 4-a cannot be visually recognized from the user's eyes. Since the stopper portion of the toilet lid stopper 2-a is directed downward, it cannot be seen from the user's eyes.

[0016]

According to the present invention, the following effects are exhibited by the above configuration.

According to the first aspect of the present invention, since the soft closing unit is prevented from being excessively rotated due to deformation of the toilet lid, even in an erroneous use in which a load is applied from above the toilet lid,
Damage to the soft closing unit can be prevented.

According to the second aspect, since the stopper is formed in the rotation direction of the hinge, the load can be easily received.

According to the third aspect, when the load is applied more than expected and breakage occurs, the performance can be restored by replacing the least expensive component.

According to the fourth aspect, the stopper is provided in a place where it is difficult for the user to visually recognize, so that the appearance is not impaired.
