Description

  The present invention relates to a toilet device that helps a toilet user to stand up after a toilet by lifting a rear portion of the toilet seat of a Western-style toilet or a portable toilet at a certain angle from the front.

Although it is known to use commercial power to drive the rear part of the toilet seat with a drive device, this drive mode allows the drive shaft to rise with the human body even when a human body load is applied. Since the shaft is accommodated by the case member, the length of the drive shaft is limited, the lifting angle is limited, and the toilet user cannot stand up.

However, since the lifting angle is as small as about 20 °, the standing width of the toilet user is small, so that the toilet user or the person who assists, for example, has a great difficulty.
Moreover, since the rising angle is small, it is difficult to remove urine and dirt between the toilet seat and the upper surface of the toilet bowl.

  The toilet device of the present invention helps the toilet user to stand up by increasing the push-up angle of the toilet in order to ease the toilet user's standing operation and, for example, the labor of the person who assists, and the assistant uses the toilet It is possible to easily hold the person, and dirt attached between the toilet seat and the upper surface of the toilet bowl increases the push-up angle of the toilet seat so that the entire upper surface of the toilet bowl can be cleaned.

  Moreover, since the toilet device of the present invention is operated manually, it can be used not only in Western-style toilets but also in portable toilets, elderly people whose physical strength has decreased in the portable toilets, and the knees and lower back that are being cared for In the case of those who are not, the arc-shaped arm after the stool is kept at the desired angle while it is raised, for example, the person who is helping can clean the toilet user's lip from the back of the toilet seat that has stood up. Since the arc arm can be stopped at any position, the height of the toilet seat can be determined according to the height of the arm, and the standing operation can be performed more easily, which solves the above problems. .

The toilet device according to the present invention is driven by a manual reversing operation of the handle 4 to sprocket 2.
Is connected to the pinion 6 via the chain 5 and rotates the gear 12 and the gear group 13 through the shaft 8 fixed to the pinion 6 to raise or raise the arc-shaped arm 1 having the rack 1a on the outer periphery. The arc-shaped arm 1 can be lowered.

  The arc-shaped arm 1 of the drive shaft according to the present invention has a height from the upper surface of the toilet bowl to the vicinity of the toilet installation floor, which is the length of the arc-shaped arm 1. Although the height from the front end Ba of the toilet seat B mounted on the toilet A to the rear end Bb of the toilet seat is shorter than the height from the floor to the toilet upper surface, the rear portion Bb of the toilet seat B rising in an inclined state is Then, it rises 45 ° or more around the toilet front part Aa.
