Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device that facilitates the opening and closing operations of the lid and toilet seat of a Western-style toilet, mainly for the disabled and the elderly.

[Prior Art and Problems] Conventionally, the lid and seat of a Western-style toilet have been opened and closed by hand. Therefore, disabled people with limited limbs have to hold on to hand gestures attached to the wall of the toilet, such as Western-style toilets for disabled people, to open and close the toilet seat. However, Western-style toilets are extremely difficult for disabled or elderly people to use.

[Purpose and Structure of the Invention The purpose of the present invention is to make it possible to easily open and close the lid and toilet seat of a Western-style toilet without bending over. A first pulley and a second pulley having the same diameter are arranged concentrically in a box with the rotating shaft of the other passed through one rotating cylinder, and one end of the rotating cylinder and the rotating shaft protrudes from the box. Its protruding ends are connected to the lid and toilet seat of a Western-style toilet via links, and a forward-reverse gear motor is installed in the box, and a driving pulley is provided on the output shaft of the gear motor. A pair of conductive pulleys are provided that can individually abut on the driving pulley and the first pulley, and the driving pulley and the second pulley, respectively, and when the defecation switch button, the urination switch button, and the close switch button are operated, the The structure is such that the first pulley and the second pulley can be rotated as appropriate.

[Function] Pressing the toilet switch button opens only the lid, and pressing the urine switch button opens the lid and toilet seat. Also, by pressing the close switch button, both the lid and the toilet seat can be closed.

[Example] 1 is a toilet bowl of a Western-style toilet, 2 is a toilet seat, and 3 is a lid. 4 was installed next to the toilet bowl. It is a box whose interior is sealed, and a mechanism for opening and closing the toilet seat 2 and lid 3 is housed in the box 4. In the drawing, a part of the side wall is removed to clarify the internal structure of the box 4, but in the drawing, 5 and 6 are the first pulley and second pulley, which have the same diameter, and are connected to the wall 7 inside the box 4. The bearings 8 are mounted on the bearings 8 and are placed in a reactive and horizontal manner. That is, the rotating shaft of the first pulley 5 is formed into a cylindrical shape, and this rotating cylinder 9
is supported by the bearing 8, and the rotating shaft 10 of the second pulley 6 is inserted into the rotating cylinder 9.

The rotary cylinder 9 and the rotary shaft IO each protrude from one side wall 4a of the box 4, and have levers 11 and 12 protruding from each protruding end, and the tip of the lever 11 is connected to one side of the lid 3 via a link 13. Furthermore, the tips of the levers 12 are connected to one side of the toilet seat 2 via links 14, respectively. Reference numeral 15 denotes a forward/reverse gear motor installed in the box 4, and its output shaft 16 is horizontally provided diagonally below the first pulley 5 and second pulley 6. Driving pulleys 17 and 18 are provided at positions corresponding to the first pulley 5 and the second pulley 6, respectively. 19.20 is a conductive pulley, and each low conductive pulley 19.20 is a pair of L-shaped members 2.
1.22 is pivoted at its bent portion to a shaft 24 installed between bearing pieces 23.23 so as to be able to rotate independently, and the first pulley 5 and Second
The pulley 6 is rotatably supported within the rotation plane of the pulley 6.

Also, the other end of each L-shaped member 21 and 22 is! &25 are connected to plungers 28, 29 of solenoids 26, 27 via springs 30, 31, respectively. Note that 32 and 33 are limit switches for detecting the forward and reverse rotation ends of the first pulley 5, and 34 and 35 are limit switches for the second pulley 6.
Limit switch that detects the forward and reverse rotation ends of 36°3
Reference numeral 7 designates brake plates attached to the rotating surfaces of the first boolean IJ 5 and the second pulley 6, respectively, in order to operate the limit switches 32, 33, 34, and 35. Further, 38 indicates a relay for electrical wiring connecting the gear motor 15, the solenoid 26, 27, and each limit switch 32, 33, 34, 35.

On the other hand, 39 is a stool switch button 40. The switch box 39 is made up of three parts, a urination switch button 41 and a close switch button 42, and the switch box 39 can be attached to a handrail 44 for the handicapped in a toilet by means of a mounting fitting 43 provided on its outer surface.

However, in the Western-style toilet lid and toilet seat opening/closing device configured in this way, for example, when the toilet switch button 40 is pressed, the gear motor 15 is turned on and the drive pulley 17 is rotated in the direction of arrow C in FIG. At the same time, the solenoid 26 is energized and the conduction pulley 19 is connected to the driving pulley 17 and the first
It comes into contact with both pulleys 5.

Therefore, the rotation of the gear motor 15 is transmitted to the first pulley 5, causing the first pulley 5 to rotate in the direction of arrow B in the figure.
Therefore, the lid 3 is rotated in the direction of arrow C in FIG. 4 and opened. When the lid 3 is opened to the normal position, the limit switch 32 is activated to stop the gear motor 15, and the soletoid 26 is simultaneously demagnetized and the conduction pulley 19 is separated from the first pulley 5. rotation is stopped. When the use is finished, by pressing the close switch button 42, the gear motor 15 will rotate in the opposite direction, and at the same time, the solenoid 1-26 will be energized by 1 degree, and the first pulley 5 will rotate in the opposite direction to the previous direction, so that the lid 3 will rotate in the opposite direction. is closed. At this time as well, when the lid 3 is closed, the gear motor 15 is stopped by the operation of the limit switch 33, and the solenoid 26 is also demagnetized.

On the other hand, when the urine switch button 41 is pressed, both solenoids 26 and 27 are energized at the same time as the gear motor 15 rotates, and the conduction pulleys 19 and 20 are respectively driven by the drive pulley 1.
7 and the first pulley 5, and the drive pulley 18 and the second pulley 6, and the rotation of the gear motor 15 is transmitted to both the first pulley 5 and the second pulley 6.

Therefore, the lid 3 and the toilet bowl 2 are rotated and opened in the direction indicated by the arrow C in FIG. 4, respectively. When the lid 3 and the toilet bowl 2 are opened to their normal positions, the limit switches 32 and 34 are activated to stop the gear motor 15. At the same time, the solenoids 26 and 27 are both demagnetized and the conduction pulleys 19 and 20 are moved to the first pulley 5.
The distance from the second pulley 6 is the same as in the case described above. Also, if the close switch button 42 is pressed at this time, the gear motor 15 will rotate in reverse and the solenoid 2 will rotate at the same time.
6.27 is re-energized, causing the lid 3 and the toilet seat 2 to
It is also similar to the case described above that both are closed.

Note that if you press the toilet switch button 40 in the wrong place and press the urine switch button 41, the lid 3 and toilet seat 2 will be opened, but by pressing the toilet switch button 40 again, the toilet seat 2 will be closed. It is electrically wired. Also, on the contrary, the urination switch button 4
If you press 1 by mistake and press the toilet switch button 40, the toilet switch button 40 can also be pressed.
By pushing again, the toilet seat 2 can be opened following the lid 3.

[Effects of the Invention] The lid and seat of a Western-style toilet can be easily opened and closed using push buttons, making it extremely user-friendly for people with disabilities. It's also more hygienic because you don't have to touch the lid or toilet bowl with your hands. In addition, as in the above embodiment, when the gear motor is stopped, if both the first pulley and the second pulley are left in a free state, it is convenient and practical to open and close the toilet seat directly by hand without relying on the push button. The value is extremely high.
