[Effect] The toilet seat can be forcibly pushed forward by the expansion and contraction of the cylinder rod.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a western-style toilet bowl having an auxiliary mechanism for standing up from a state of sitting on a toilet seat.

[0002]

[Prior Art]

 Conventionally, a Western-style toilet has a toilet seat that can be seated on the upper end of the toilet body, and thus is easier to use than a Japanese-style toilet. Generally, the toilet seat is connected to a hinge shaft attached to the rear end of the toilet body, and is a flip-up type in which the front side can freely rotate in the vertical direction.

[0003]

[Problems to be solved by the device]

 However, it is not easy to stand up from the state of sitting on the toilet seat, which is rather a pain for the elderly.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a western-style toilet bowl that can automatically lift the toilet seat forward so as to assist in standing up. There is

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the western-style toilet of the present invention rotatably connects the front part of the toilet seat to the front part of the toilet body, and the rod of a retractable cylinder is pivotally attached to the rear part of the toilet seat. The present invention is characterized in that a switching mechanism for switching the expansion / contraction movement of the rod is provided.

[0006]

[Action]

 The cylinder can also be driven by the water pressure of the water supply, etc., and does not need to be limited to pneumatic or hydraulic equipment. The flow path of such a power source is switched by the switching valve to operate the expansion and contraction of the cylinder rod. Switching the valve in the direction of extension of the cylinder rod lifts the rear part of the toilet seat, helping the person sitting on the toilet seat to stand up. If the valve is switched to the reverse flow path, the cylinder rod retracts and the toilet seat descends. When cleaning the toilet bowl, etc., if the toilet seat is flipped up as it is, the front part is lifted up with the rear part as the center of rotation.

【Example】

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of the present invention, in which a toilet seat 3 of a western-style toilet 1 is rotatably attached to a front portion of an upper end of a toilet body 1a, and a raised portion is provided at a rear portion of the toilet seat 3. At the same time, the tip of the cylinder rod 5 is connected and connected via a shaft. Similarly, the bottom end of the cylinder 7 is also connected via a shaft to the floor side, for example, the pedestal 9 of the toilet 1. The cylinder 7 also has a three-way valve (not shown) or is mounted on a wall surface where the three-way valve is easy to operate, so that water supply is connected through the three-way valve. The cylinder 7 is driven by switching the flow path of tap water with the three-way valve. When the cylinder rod 5 is retracted, the toilet seat 3 is fitted on the upper end surface of the toilet 1. When the cylinder rod 5 is extended, the rear part of the toilet seat 3 is lifted up with the front part of the toilet body 1a as the center of rotation. This assists the person sitting on the toilet seat 3 to get up. In this case, the cylinders 7 are preferably provided on both sides of the rear portion of the toilet seat 3.

Hereinafter, another embodiment of the present invention will be described by assigning the same reference numerals to the same components as those of the above-mentioned embodiment.

In the embodiment shown in FIG. 2 and subsequent figures, in addition to the toilet seat 3, for example, an auxiliary toilet seat 11 as shown in FIGS. 5 and 6 is provided. The front portion is pivotally attached to the front portion of the toilet seat 3, and the rear portion is pressed from above by a swingable lever 13. The lever 13 is configured to urge its front end downward by a coil spring 15 that is contracted between the lever 13 and a pedestal 1b projecting from the rear of the toilet body 1a, and is formed at the front of the lever 13. The downward bent portion is engageable with the upward bent portion formed at the rear end of the auxiliary toilet seat 11. When the cylinder rod 5 is extended, the rear portion of the toilet seat 3 is lifted up with the front portion of the auxiliary toilet seat 11 as the center of rotation (see FIG. 3). At this time, the lever 13 prevents the rear portion of the auxiliary toilet seat 11 from rising up with the toilet seat 3. Further, in order to flip up the toilet seat 3 and the auxiliary toilet seat 11 rearward, the front portion of the auxiliary toilet seat 11 is lifted upward to overcome the urging force of the spring 15 and disengage from the lever 13 (see FIG. 4). ). As described above, when the toilet seat 3 is repelled, it is desirable that the auxiliary toilet seat 11 and the toilet seat 3 are integrally housed without being separated from each other, so that the magnet 17 is provided on one of the contact surfaces facing the free ends. Is attached, and an iron piece is embedded on the other surface. A hinge 19 for pivotally attaching to the toilet seat 3 is provided at the front of the auxiliary toilet seat 11.

[0010]

[Effect of the device]

 As described in detail above, according to the Western-style toilet bowl of the present invention, the rear part of the toilet seat can be forcibly pushed up forward by the cylinder, so that the burden on the sick person, the physically handicapped person, or the elderly person is particularly high. There is an effect that can be assisted to reduce.
