Abstract

PURPOSE:To enable the opening or closing operation of a closet seat and a closet seat cover to be performed just by the foot operation of a pedal by engaging operating cables with respective arms, to be thrust into the arms, respectively in loosely fitted states in the direction for closing the closet seat and the closet seat cover, and by engaging the cables with the arms to be brought in contact with each other via a stopper in the direction for opening them, to have bringing-in-contact pieces for pushing the respective arms when they are set in opened states. CONSTITUTION:When a foot pedal 17 is stepped on in the closed state of a closet seat cover 8, then by the rotational movement of a push bar 19, an oscillating piece 22 is pressed by stroke l in the left direction, and a contact piece 30 is moved by the stroke l in the right direction. Then, a closet seat cover opening operating cable 27 is pulled nearer in the first left direction, and by a stopper 29, an arm 13 is rotationally moved clockwise, and via a closet seat cover shaft 6, the closet seat cover 8 is opening-worked into a standing posture from a falling posture. When the closet seat cover 8 is set in an opened state, then the cable 27 is thrust into the arm 13 in a state fitted loosely on the arm 13, and so the cable 27 is independently moved in the right direction, and the arm 13 is released from constraint with the stopper 29 fitted on the tip side of the closet seat cover opening operating cable 27, and so with manual operation, the closet seat cover 8 can be closing-worked in the falling posture from the standing posture.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention provides two toilets placed near the toilet body when a man uses a Western-style toilet to finish his errands or a woman uses a Western-style toilet. The present invention relates to a device that allows a toilet seat and a toilet lid to be opened and closed without using one's hands simply by selectively operating a foot pedal.

[Conventional technology]

Usually, in a Western-style toilet, the toilet seat and the toilet lid 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 a reclined toilet seat placed on the upper surface of the periphery of the toilet bowl.

[Problem to be solved by the invention]

However, such opening/closing operations of the toilet seat or toilet lid have conventionally been performed by the user in a bent-down position using his or her hands.

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, the physically disabled, and the like.

Additionally, the toilet bowl itself cannot be said to be kept clean at all times, especially in public restrooms.If you bend down to open or close the toilet seat or toilet lid, the dirt on the toilet bowl body will become visible. It also has the disadvantage that it sticks to the skin, gives off an odor, and is unpleasant.

(Means for Solving the Problems) The present invention improves and eliminates the above-mentioned problems of the conventional art, and allows the toilet seat and toilet lid to be removed by simply stepping on a pedal placed near the toilet bowl body. The purpose of the present invention is to provide a device that can be opened and closed.

Therefore, the means adopted by the present invention in order to solve the above problem is a total of two pedals for opening and closing the foot-operated toilet seat and toilet lid, which are placed near the toilet main body, and the rotation of both pedals. t5 for opening and closing the toilet seat and toilet lid that are pushed and pulled; consists of an operating cable and arms of the toilet seat shaft and the toilet lid shaft connected to the other end of each of these cables; Each opening operation cable is inserted into and engaged with each arm in a loose state in the direction of closing the toilet seat and the toilet lid, and is abuttingly engaged with the arm via a stopper in the direction of opening the toilet seat and the toilet lid. Each of the operating cables for opening the toilet seat and the toilet lid has an abutment piece that pushes each arm by a predetermined stroke when the toilet seat and the toilet lid are in an upright open state.

[For production]

When the foot pedals for the toilet seat and the toilet lid are depressed and rotated, the opening operation cables for the toilet seat and the toilet lid are pulled. As a result, the arms of the toilet seat shaft and the toilet lid shaft, which are connected to the distal ends of the operating cables, respectively rotate. Thereby, it is possible to open the toilet seat and the toilet lid from the reclining position to the standing position. Note that if only the toilet seat is opened when both the toilet seat and the toilet lid are in the closed state in the reclined position, the toilet lid will also be opened together.

Also, when the toilet seat and toilet lid are rotated by pressing the foot pedals from the open position in an upright position, the tips of the opening operation cables for the toilet seat and toilet lid push the arms of the toilet seat shaft and the toilet lid shaft. . As a result, the toilet seat and the toilet lid are rotated to a reclining position and are in a closed state.

Note that when both the toilet seat and the toilet lid are in the open state, if only the toilet lid is closed, the toilet seat will also be integrally closed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below based on embodiments shown in the drawings.

1st t! 1 to 3 relate to the first embodiment of the present invention, in which FIG. 1 is a longitudinal sectional view showing the opening/closing mechanism 1 of the toilet seat and toilet lid, and FIG. 2 is a portion of the mechanism 1. The cross-sectional plan view and FIG. 3 are longitudinal cross-sectional views showing the pedal mechanisms 2 for opening and closing the toilet seat and the toilet lid. Note that the pedal mechanism for opening and closing the toilet seat and the pedal mechanism for opening and closing the toilet lid have exactly the same configuration.
In the drawing, only one is shown for convenience of explanation. In this embodiment, as shown in FIG. 1, a toilet seat box 4 is fixedly installed on the rear upper surface of the toilet main body 3, and a toilet seat shaft 5 and a toilet lid shaft having a double shaft structure are attached to the toilet seat box 4. A toilet seat 7 and a stool M8 are each rotatably supported via a toilet seat M8.

The opening/closing mechanism 1 for the toilet seat 7 and the toilet lid 8 is built into the toilet seat box 4. That is, pinions 9.9 are fixed to the toilet seat shaft 5 and the toilet lid shaft 6 in the toilet seat box 4, respectively, and the pinions 9, 9 are connected to the sector gears 10.9.
It meshes with 10. Shaft 11 of sector gear 10.10.
Arms 12 and 13 are attached and fixed to 11.

Further, on the inner wall surface of the toilet seat box 4, SIDIC absorbers 14, 14 are installed to reduce the rocking of the arms 12 and 13 in the counterclockwise direction in FIG.

On the other hand, each of the pedal mechanisms 2 of the toilet seat 7 and the toilet lid 8 is arranged in the vicinity of the toilet main body 3, and is configured as shown in FIG. 3. That is, a foot pedal 17 is rotatably attached to the recovered body 15 via a return spring 16. A sector small gear 18 is provided on the other end side of the pedal 17.

This gear 18 includes a pusher 19 and a sector large gear 2.
Each pusher 19 for the toilet seat and toilet lid, which is engaged with the binion 21 provided with
(see figure).

In addition, each sector large gear 20 for the toilet seat and toilet lid is connected via a rack 25 to operation cables 26 and 2 for opening the toilet seat and toilet lid.
7 (see Figure 2). still,
In Fig. 3, 28 indicates each open operation cable 23.24.
This is a return spring.

The other end side of the operating cable 26.27 for opening the toilet seat and toilet lid is inserted into an arm 12.13 for rotating the toilet seat shaft 5 and toilet lid shaft 6, respectively, and is latched by a stopper 29. There is. Therefore, each open operation cable 26.
27 can rotate the arm 12.13 clockwise in FIG. 1 via the stopper 29, but can freely move in the opposite direction relative to the arm 12.13. be. On the other hand, the arm 12.13 is located on the 6 & 1 side of the operating cable 23.24 for opening the toilet seat and toilet lid.
Abutment pieces 30, 30 are attached to the base of the holder, which are located opposite to each other. The abutting pieces 30.30 move the arms 12 and 13 by a stroke l when the arms 12 and 13 are in the state shown by the chain line in FIG. 1 (only arm 13 is shown in FIG. 1). The counterclockwise direction is to hebusche.

Next, the operation mode of the first embodiment device configured as described above will be explained based on a case where a woman uses it and a case where a man defecates. In this case, the toilet lid 8 is opened and closed for use.

In the state before use, as shown in Figure 1, the toilet seat 7
The toilet lid 8 is placed on the upper surface of the toilet main body 3 around the toilet bowl in a collapsed position, and is in a closed state. From this state, the user approaches the toilet main body 3 and, while standing, depresses the foot pedal 17 for opening and closing the toilet lid by about 15 degrees. In response to this depression angle, the sector pinion 18 begins to rotate clockwise in FIG. 3. As a result, the pusher 19 attached to the binion 21 and the large sector gear 20 begin to rotate.

Due to the rotation of the pusher 19, the swinging piece 22 is pushed by a stroke l to the left in FIG. It is moved by the stroke l to the right in the figure.

However, in this state, the arm 13 on the toilet lid shaft side is in the state shown by the substantially solid line in FIGS. 1 and 2, and the movement of the stroke 1 of the abutment piece 30 is an independent operation.

Also, due to the rotation of the sector large gear 20, the rank 25 is moved to the third position.
Move by stroke L to the right in the figure. This results in
The toilet lid opening operation cable 27 is pulled to the left in FIGS. 1 and 2, and the stopper 29 is moved to the arm 1 on the toilet lid shaft side.
3 in the clockwise direction in FIG. 1 by about 55 degrees. Therefore, the binion 9 whose rotation angle is expanded through the sector gear 10 rotates approximately 110 degrees counterclockwise in the figure, and as a result, the toilet lid 8 is folded down through the toilet lid shaft 6. You will be able to move from a posture to a standing posture. That is, the user can open and use the toilet lid 8 by simply stepping on the pedal 17 without using his/her hands while standing near the toilet main body 3. Therefore, it is possible to use the toilet bowl main body 3 without having to bend down or take an unreasonable posture, which is extremely convenient.

The relationship between the depression angle of the foot pedal 17 and the movement strokes E and L of the operating cables 24 and 27 for opening and closing the toilet lid is as shown in FIG. 4.

After the stool M8 is opened, when the foot is removed from the foot pedal 17 for opening and closing the toilet lid, the ifL return spring 28 rotates the pedal 17 back to the state shown by the solid line in FIG. This rotational movement causes the rack 25 to return to the position shown by the solid line in FIG. 3 via the large and small sector gears 18 and 20.

This operation of the rack 25 is transmitted to the tip side of the toilet lid opening operation cable 27. However, the toilet lid opening operation cable 2
7 is inserted into the toilet lid shaft side 7-m 13 in a loose state, and since the toilet lid 8 is in the open state, the cable 27
moves independently to the right in FIG. 1 and returns to the standby position.

Therefore, in this state, the arm 13 is released from the restraint of the stopper 29 attached to the tip side of the toilet lid opening operation cable 27, and the toilet lid 8 is manually closed from the upright position to the collapsed position. It is possible to do so.

On the other hand, during the return operation of the foot pedal 17 for opening and closing the toilet lid, the pusher 19 comes into contact with the swinging piece 22. However, the rotation return operation of the pusher 19 is in the clockwise direction in FIG. 3, and the swinging piece 22 can freely swing in this clockwise direction. Therefore, the swinging of the swinging piece 22 does not move the toilet lid opening operation cable 24. In other words, the return operation of the foot pedal 17 is unrelated to the opening/closing operation of the toilet lid 8.

Next, after using the toilet body 3, the user operates the foot-operated pedal 17 for opening and closing the toilet lid to lower the toilet lid 8 from the open state to the closed state. When the foot pedal 17 for opening/closing is lightly stepped on, the sector pinion 18
via pinion 21 and pusher 19. The sector large gear 20 begins to rotate counterclockwise in FIG. As a result, the pusher 19 moves the swinging piece 22 by a stroke l to the left in FIG.
When the toilet lid 8 is open, the arm 13 on the toilet lid shaft side is at the position shown by the chain line in FIG. It is in.

Therefore, the abutment piece 30 pushes the arm 13 by two strokes, causing it to rotate counterclockwise. Therefore, the toilet lid shaft 6 is urged to rotate in the direction of the hour hand through the sector gear 10 and the pinion 9, and the toilet lid 8 closes from the upright position to the collapsed position with the help of its own weight. Of course, the impact of the closing operation of the toilet lid 8 is alleviated by the silk absorber 14 at its terminal end, allowing it to come into gentle contact with the toilet seat 7.

M stroke! After returning the toilet lid 8 to the closed state by rotating the bushing par 19 by the number of times i1J, it is only necessary to return the foot-operated pedal 17 for opening and closing the toilet lid.
When operating from the open state to the closed state, the foot-operated pedal 17 for opening and closing the toilet lid only needs to be depressed only slightly. Furthermore, when the pedal 17 is depressed, the rack 25 is also slightly depressed via the sector large gear 20. amount, move to the right in Figure 3.

However, the movement of the stopper 29 attached to the tip side of the toilet lid opening operation cable 27 is only when the arm 13 on the toilet lid shaft side is in the state shown by the chain line in FIG. Therefore, the pedal operation to close the toilet lid 8 is performed regardless of the clockwise rotation of the arm 13, and the toilet lid 8 is opened. Never.

In this manner, in the device of the first embodiment, the toilet lid 8 can be opened and closed simply by depressing the foot-operated pedal 17 for opening and closing the toilet lid. By the way, this opening/closing operation is the same when opening/closing the toilet seat 7.
To open and close the toilet seat 7, use the foot pedal 17 for opening and closing the toilet seat.
The operation can be performed in the same manner as described above, and the operation mode is exactly the same as the opening/closing operation of the toilet lid 8.
A description of the opening and closing operations of the toilet seat 7 will be omitted here.

Note that when the toilet seat 7 is opened from the closed state in which both the toilet seat 7 and the toilet lid 8 are in a reclining position, the toilet iB also moves integrally with the opening operation of the toilet seat 7. Also, toilet seat 7
When only the toilet lid 8 is operated to close from the open state in which both the toilet M8 and the toilet M8 are in an upright position, the toilet lid 7 is also integrally closed.

FIG. 5 shows a second embodiment of the invention. In this embodiment, the opening/closing mechanism 1 of the toilet seat 7 and toilet lid 8 is provided in a protruding manner toward one end of the toilet seat box 4. The basic configuration and effects are exactly the same as those of the first embodiment described above, so a description thereof will be omitted here.

By the way, the present invention is not limited to the above-mentioned embodiments, and can be modified as appropriate. Although the connection is made through the pinion 21 and the sector gear 20, it is also possible to connect it directly to the rotating part of the pedal 17. It is also possible to attach the arms 12 and 13 directly to the toilet seat shaft 5 and the toilet lid shaft 6.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to open and close the toilet seat and the toilet lid by simply stepping on the foot pedal while standing near the toilet main body. Therefore, the user does not have to bend down or take an unreasonable posture to open and close the toilet seat and toilet lid, which is extremely convenient. Furthermore, since there is no need to approach the filth and the like attached to the inner surface of the toilet bowl, there is no need for discomfort.
