Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a toilet seat that allows men to use a Western-style toilet to open and close the toilet seat and the toilet bowl without using their hands when they use a Western-style toilet. [Prior Art 1] Usually, in a Western-style toilet, the toilet seat and the toilet are pivotably supported on the rear upper surface of the toilet main body so that they can be opened and closed. When a man does errands, he opens both the toilet lid and the toilet seat and holds them in an upright position. Also, when used by women and when men defecate,
Only the toilet lid is opened and held in an upright position, and the user sits on the toilet seat in a reclined position placed on the upper surface of the periphery of the toilet bowl. After use, the toilet seat and toilet lid are closed and held in a reclined position.

[Problem to be Solved by the Invention 1] However, conventionally, the user has used his or her hands to open and close the toilet seat or the toilet lid. As a result, each time I use the toilet, I am forced to sit in a cramped position.
I felt uncomfortable. A cramped posture is an extremely serious problem for the elderly, the sick, and those who are in need of a healthy body. Also, the toilet itself cannot be said to be always kept clean. Especially in public restrooms, if you bend down to open and close the toilet seat or lid, you may see the dirt on the toilet bowl, feel the odor, and feel uncomfortable. There was also. [X! i! Means for Solving the Problem 1 The present invention solves and eliminates the above-mentioned problems of the conventional art, and it is necessary to open and close the toilet seat and the toilet lid without touching the toilet seat and the toilet lid. The aim is to provide a device that can do this. The first means adopted by the present invention in order to solve the above problem is two arms connected to the toilet seat shaft and the toilet lid shaft, and an arm on the toilet seat shaft side when moving the toilet seat forward from the backward position in the listening direction. As it comes into contact with the slaughter, move from the forward position to the m retreat position 4

It moves backward from STS to the simulated abdication NA and stops. An electric toilet seat closing device 17 made of an electromagnetic solenoid or the like is arranged near the base of the arm 10. When this toilet seat closing operation tool 17 receives a start signal, the output end 17a protrudes and pushes the base of the arm 10 in the toilet seat open position shown by the two-dot chain line to a position where the toilet seat 6 can be closed by its own weight. , the output end 17a is automatically retracted. Note that this toilet seat closing operating tool 17 can also be omitted. The toilet lid opening/closing mechanism 2 that opens and closes the toilet 126 is different from the toilet seat opening/closing mechanism 1 because the object to be opened and closed is different, but the basic structure is the same. That is, on the toilet lid shaft 25,
As shown in FIG. 2, a pinion 27 is fixed and meshes with a sector gear 28. An arm 30 is attached and fixed to the shaft 29 of the gear 28. A shock absorber 31 is installed in the holding box 4 to reduce the swinging motion of the arm 30. On the bottom wall surface 4b of the toilet seat box 4, a rack 32, which is a toilet lid opening operating tool 33, is slidably arranged. When the rack 32 moves forward from the retracted position to the forward position, the rack engagement piece 'PA32a presses the bin part 30a of the arm 30 to swing the arm 30 from the toilet lid closed position to the toilet lid open position. do. When the arm 30 is in the toilet lid open position, the toilet lid 26 maintains an independent upright position, so even if only the rack 32 is moved backward from the forward position to the retracted position, the arm 30 remains in the toilet seat open position. Stay stopped. The rack 32 meshes with an output gear A735 of a servo motor 34, which is an electric drive tool, via an intermediate gear A736. Upon receiving the activation signal, the servo motor 34 rotates forward to move the rack 32 forward from the retraction stop position to the forward position, and then automatically rotates reverse to move the rack 32 backward from the forward position to the retreat position. and stop. arm 30
An electric toilet lid closing device 37 made of an electromagnetic solenoid or the like is arranged near the base of the toilet lid. When this toilet lid closing operation tool 37 receives an activation signal, the output end 37a protrudes, and after pushing the base of the arm 30 in the toilet seat open position to a position where the toilet lid 26 can be closed by its own weight, the output end 37a automatically moves backwards. The switch that issues a start signal to the servo motor 14.34 and the switch that issues a start signal to the toilet seat closing device 17 and the toilet lid closing device 37 are not shown, but are contact type switches such as hand push type or foot push type. Alternatively, it may be a non-contact type switch such as a phototube type, and is placed on the wall of the toilet so that the user can operate it while standing near the toilet main body 3. Next, the operation mode of the apparatus of this embodiment configured as described above will be explained. First, as shown in FIG. 1, the toilet seat 6 and the toilet lid 26 are placed on the upper surface of the toilet main body 3 around the toilet bowl in a reclining position.
Assume that it is in the closed state. From this state, when the man goes to do some errands, he turns on a switch that issues a start signal to the servo motor 14 of the toilet seat opening/closing mechanism 1. Then, servo motor 1
4 rotates forward to move the rack 12 forward from the backward stop position mA to the forward position B, and then automatically rotates in the reverse direction to move the rack 12 backward from the forward position 8 to the backward position and then stops. Become. This forward movement and rotation of the rack 12 causes the arm 10 to rotate approximately 55 degrees clockwise in FIG. 1. Therefore, the rotation angle of the pinion 7 is expanded through the gear 8, and the pinion 7 rotates approximately 1100 degrees counterclockwise in the same figure, and as a result, the toilet seat and others are raised from the reclined position through the toilet seat shaft S. You will be able to open your posture. The toilet 126 is lifted by the toilet seat 6 during the opening operation, and the toilet 126 is opened from the lying position to the standing position. That is, a male user can open the toilet seat 6 and the toilet lid 26 to perform errands by simply turning on the switch without using his hands. Therefore, it is possible to use the toilet bowl main body 3 without having to bend down in an unreasonable posture, which is extremely convenient. Next, a case will be described in which a male user, after finishing his errands, moves only the toilet seat 6 from the open state to the closed state. After using the toilet main body 3, a switch that issues a start signal to the toilet seat closing operating tool 17 is turned on. Then, the output end 17a of the toilet seat closing operation tool 17 protrudes.
After the arm 10 is pressed near the base of the toilet seat position ff1D, indicated by the two-dot chain line, to a position where the toilet seat 6 can close by itself, the output end 17a is automatically moved back to standby. The arm 10 is rotated counterclockwise by the bush at the output end 17a. Therefore, the toilet seat shaft 5 is biased clockwise through the gear 8 and the pinion 7, and the toilet seat 6 is closed from the upright position to the collapsed position F! I'm starting to lff. Of course, toilet seat 6
The closing action of the I? The shock absorber 11 at the end reduces the impact, allowing gentle contact with the toilet main body 3. After the male user finishes his errands, the toilet seat 6 and toilet lid 2 are
8. When both stools 1 and 8 are toppled from the open state to the closed state,
If only the toilet seat 126 is forcibly closed, the toilet seat 6 will also be closed together, so it is only necessary to turn on a switch that issues a start signal to the toilet lid closing device 37. Turn this switch to O
When set to N, the output end 37a of the toilet lid closing operation tool 37 protrudes, and after pushing the base of the arm 30 in the toilet lid open position to a position where the toilet lid 26 can be closed by its own weight, the output end 37a is pushed out. It will automatically move back and wait. The arm 30 is rotated in the toilet lid closing direction by the bush at the output end 37a. Therefore, the toilet lid shaft 25 is urged to rotate in the toilet lid opening direction via the gear 28 and the binion 27.
The stool 126 begins to perform a closing operation from the standing position to the lying position. Of course, the impact of the closing operation of the toilet 126 is alleviated by the stain absorber 31 at its terminal end, allowing it to come into gentle contact with the toilet main body 3. Note that it is also possible to close the toilet seat 6 and the toilet lid 26 from the upright position to the collapsed position by manual operation. Next, as shown in FIG. 1, the toilet seat 6 and the toilet! 26 is a toilet lid opening/closing mechanism, as shown in FIG. Turn on the switch that issues a start signal to the second servo motor 34. Then, the servo motor 34 rotates forward and rotates the rack 32.
To avoid moving forward from the backward stop position to the forward position, the rack 32 is automatically rotated in reverse to move the rack 32 backward from the forward position to the backward position and then stopped. This rack 32
The forward movement causes the arm 30 to rotate approximately 556 degrees in the toilet lid opening direction. Therefore, the pinion 27 whose rotation angle is expanded through the gear 28 is 110
As a result, the toilet lid 5 is opened from the reclining position to the standing position via the toilet lid shaft 25. In other words, the user can open the stool I5 simply by turning on the switch without using his/her hands! It is possible to add your own needs. Therefore, it is possible to use the toilet main body 3 without having to take an awkward bent-down posture. When a woman or a man lowers the toilet lid 26 from the open state to the closed state after finishing his errands, as mentioned above, the toilet lid 26 is closed. (7)
All that is required is to turn on a switch that issues a start signal to the operating tool 37. (Second Embodiment) FIGS. 3 and 4 show a second embodiment of the present invention, in which FIG. 3 is a vertical sectional side view and FIG. 4 is a partially sectional plan view. The difference between this embodiment and the first embodiment is that the toilet seat opens and closes v.
Toilet lid opening operating tool 43 that rotates the arm 10 of 1 structure 1
and a toilet lid opening operating tool 53 that rotates the arm 30 of the toilet lid inter-lid mechanism 2. The toilet seat closing operation tool 43 consists of a crank 42 fixed to the output shaft 14a of the servo motor 14, and when the crank 42 rotates counterclockwise from the backward position i1E to the forward position (Q@F in FIG. 3), crank 4
The arm 10 is rotated by the bin 42a attached to the tip of the arm 10 from the toilet seat closed position C shown by the solid line to the toilet seat open position shown by the two-dot chain line. As shown in FIG. 4, the toilet lid opening operating tool 53 consists of a crank 52 fixed to the output shaft 34a of the servo motor 34, and when the crank 52 rotates from the backward position to the forward position, Move the arm 30 from the toilet lid closed position to the toilet lid I? with the bottle 52a attached to the tip. ! 1
Rotate to position. This is the same as in the first embodiment described above, except that the toilet seat closing operating tool 43 and the toilet lid opening operating tool 53 are replaced by cranks 42 and 52, so the explanation here will be omitted. (Other Examples) The present invention is not limited to the above-mentioned examples,
Appropriate changes are possible. For example, arms 10 and 30
is directly attached to the toilet seat shaft 5 and the toilet lid shaft 25. Effects of the Invention As described above, according to the present invention, it is possible to open and close the toilet seat and the toilet lid while standing near the toilet main body.
