DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for opening and closing a toilet lid and a toilet seat of a Western-style toilet bowl, and more particularly to a barrier-free demand for a public toilet.

[0002]

2. Description of the Related Art Western style toilets for public use have been developed. The Western toilet is convenient for both young and old, because the burden on the body is light in the posture when adding a toilet, but it requires opening and closing operations of a toilet lid and a toilet seat when used. Therefore, when they are dirty, it is extremely difficult to use, and the use may be hesitated. Therefore, a manual type (for example, Japanese Utility Model Application Laid-Open No. 63-15797) and a foot pedal type (for example, Japanese Patent Publication No. 4-76698) have been proposed.
An opening / closing device for an electric toilet (for example, Japanese Unexamined Patent Publication No. 3-158121), such as a toilet lid, of a Western-style toilet bowl is disclosed.

A common matter in the conventional toilet lid opening / closing technology disclosed in the above publication is that an input system for opening / closing a toilet lid or the like is one system by hand or foot, including operation of an electric switch. In addition, the members constituting the Western-style toilet bowl are of a special specification for mounting a manual operation arm, a mounting shaft for a foot pedal is required on a ceramic toilet body, or a support shaft for a toilet lid is provided. It can be found that it cannot be attached to an existing Western-style toilet, for example, a casing that houses a motor and a drive mechanism is integrated at the rear.

[0004]

An input system for opening and closing a toilet lid and the like includes a manual operation of an electric switch.
The fact that it is a single system by hand or foot means that it may be difficult to use it for people with hand or foot disabilities, and for electric motors, some escape mechanism is included in the configuration Unless the electric system breaks down, the opening / closing operation of the toilet lid or the like may become difficult unless the electric system breaks down. In addition, the fact that it is not possible to attach it to an existing Western-style toilet bowl means that the utility value of today's Western-style toilet bowls is not sufficient, and in order to use it, the entire toilet bowl must be replaced. There is a problem that the economic loss at the expense of use is too large.

[0005] In view of the problems presented by the prior art, the present invention can be conveniently used by both healthy persons and persons with limited limbs, and can be easily attached to existing Western-style toilets. An object of the present invention is to provide a highly practical Western-style toilet lid and toilet seat opening / closing device, and employs the following means to achieve this objective.

[0006]

Since the shaft is connected, the operating force is also transmitted from the toilet seat drive shaft to the toilet lid drive shaft via the electromagnetic clutch. Therefore, when the opening operation of the toilet seat is selected, the toilet lid and the toilet seat are simultaneously opened. On the other hand, when the foot pedal for selecting the closing operation of the toilet lid or the toilet seat is operated while the toilet lid is open, the operating force is transmitted to the toilet lid arm via the toilet lid drive shaft, and the toilet lid is closed. Can be Also, when the toilet seat or the foot pedal for selecting the closing operation of the toilet seat is operated in a state where the toilet seat is opened, the toilet clutch drive shaft and the toilet seat drive shaft are connected by the electromagnetic clutch. Is transmitted to the toilet lid arm and the toilet seat arm, and the toilet seat and the toilet lid are simultaneously closed.

When the user of the Western-style toilet selects the electric operation by the operation switch, the driving force of the motor is transmitted to the toilet lid driving shaft and the toilet seat driving shaft instead of the operation force of the foot pedal, and It works in the same way as pedal operation. However, since the motor is driving the toilet lid drive shaft, the direction of power transmission when the toilet seat opening operation is selected is the direction in which the power is transmitted from the toilet lid drive shaft to the toilet seat drive shaft via the electromagnetic clutch. Changes to

A toilet lid drive shaft and a toilet seat drive shaft in the toilet lid and toilet seat opening / closing device of a Western toilet output both shafts to the left and right of the casing, and the toilet lid arm and the toilet seat arm can be used for both left and right. .

In this configuration, if space for installing the toilet lid and toilet seat opening / closing device is not secured on the right side of the existing Western toilet, this is installed on the left side of the Western toilet, and the toilet lid arm and the toilet seat arm are installed. Can be attached to the right output shaft to open and close the toilet lid and toilet seat. Conversely, if there is not enough space on the left side of the Western style toilet to install the toilet lid and toilet seat opening / closing device, install it on the right side of the Western style toilet and attach the toilet lid arm and toilet seat arm to the left output shaft. Attached to open and close the toilet lid and seat.

A motor and a toilet lid drive shaft of a drive device such as a toilet seat are coupled so as to be capable of transmitting rotation at all times, and the motor is configured to brake the toilet lid drive shaft when opening and closing the toilet lid and the like by a foot pedal. Can be.

[0013] In this configuration, the motor and the toilet lid drive shaft are coupled to each other so as to be able to transmit rotation at all times. Therefore, when the toilet pedal is opened or closed by a foot pedal that is not actively driven, the motor is not operated. As the lid driving shaft rotates together with the rotation of the lid drive shaft as a braking load, it is possible to impart a stepping response to the foot pedal and to limit the opening / closing speed of the toilet lid and the like.

An operation switch in the toilet lid and toilet seat opening / closing device includes a main operation switch directly attached to the casing,
Two systems including a cord-type remote operation switch can be provided.

In this configuration, one operation switch bears a backup function of the other operation switch, and any operation switch opens and closes the toilet lid and the like.

Can be installed. Generally, it may be installed on the right side of the toilet body 51 in consideration of the convenience of a right-handed user, and it is preferable to install it on the left side only when installation space cannot be secured on the right side. Therefore,
The case of installation on the right side will be described (FIG. 1). In addition,
In a Western style toilet 50 exemplified as a drive target of the toilet lid and toilet seat opening / closing device 10, a toilet seat 53 covers a peripheral portion of a toilet body 51, and further, a toilet lid 52 entirely covers the toilet seat 5 from above.
3 and the toilet lid 52 are generally mounted on a common mounting shaft so as to be freely opened and closed.

The height of the toilet lid drive shaft 16 and the like is adjusted to an intermediate height between the toilet lid 52 and the toilet seat 53 by using the adjust leg 12, and the position of the toilet lid drive shaft 16 and the like is adjusted. After the front and rear positions are adjusted so as to approach the mounting shaft of the toilet lid 52, the fixing base 12b is fixed with a wood screw or a concrete screw to complete the process.

Are tightened so that the sub arm 37c of the toilet seat arm 37 is placed on the upper edge of the toilet body 51,
Close. Next, the sub arm 36c of the toilet lid arm 36 is placed on the toilet seat 53, the embedded screws b2, b2,... Are tightened, and the toilet lid 52 is closed. After this, the toilet lid arm 36
The holding plate 36b is attached to the
6c and the holding plate 36b. The remote operation switch 15B connects the plug 15e to the socket 1
5f, and the main body is hung on the wall surface of the toilet or the like to complete the mounting work. Therefore, for example, it is possible to unitarily attach to the existing Western-style toilet 50 of a public toilet such as a road parking lot, and the casing 11
Because of having a waterproof structure, it is possible to withstand washing by water discharge.

Here, the user of the Western-style toilet bowl 50 selects the opening operation of the toilet lid 52 using the foot pedal 13 or the main operation switch 15A or the remote operation switch 15B, and then closes the toilet lid 52. The case of selection will be described (FIG. 4).

When the toilet lid opening pedal 13a is depressed,
The middle bending arm 26 extends from the bending posture, and as a result, the gear G5 is pushed and turned in the direction of the arrow K2 (FIG. 4).
(B)). The rotation of the gear G5 is transmitted to the gear G4, and the gear G4 turns in the direction of the arrow K3. The rotation of the gear G4 is transmitted to the gear G3 via the intermediate shaft 18, and the gear G3 turns in the same direction of the arrow K3 (FIG. 4A). Also, gear G
3 turns the gear G2 in the direction of the arrow K2, and as a result, the toilet lid drive shaft 16 rotates, and the toilet lid arm 36 attached to the toilet lid drive shaft 16 changes the posture from the horizontal posture to the vertical posture. At a predetermined angle. At this time, the toilet lid arm 36
Is opened so as to push up the toilet lid 52 by the sub-arm 36c inserted under the toilet lid 52 (FIG. 5). At this time, even if the toilet lid 52 is opened by 90 degrees or more, since the upper surface side of the toilet lid 52 is pressed by the pressing plate 36b, the toilet lid 52 does not fall backward. When the toilet lid 52 is opened, the electromagnetic clutch 28 does not operate, so that the toilet seat drive shaft 17 and the toilet seat opening pedal 13b do not operate.

During this operation, the gear G2 is
In addition to operating the second pedal 2, the bending arm 26 of the closing pedal 13c connected thereto is bent from the extended position, so that the closing pedal 13c performs a rising operation opposite to the toilet lid opening pedal 13a ( FIG. 4 (A),
(B)). Further, the gear G2 drives the output shaft 21a of the motor 21 to depolarize via the gear G1 that meshes with the gear G2. Motor 2
1 is a braking load when the gear G2 rotates, and the toilet lid 5
2 can open gently. Also,
The opened toilet lid 52 is closed by depressing the raised closing pedal 13c so that all the members operated by the toilet lid opening pedal 13a return to the original positions. In other words, when the bending arm 26c of the closed pedal 13c that has been bent is extended, the gear G2, the gear G
The toilet lid drive shaft 16 to which the toilet lid 2 is attached, and the toilet lid arm 36 attached to the toilet lid drive shaft 16 are driven to rotate in the direction of arrow K3, the toilet lid 52 is closed, and the gear G3 meshing with the gear G2 is turned to the arrow. The gear G5 is rotationally driven in the direction K2, and the gear G5 is rotationally driven in the direction of arrow K3 via the intermediate shaft 18 and the gear G4. Then, the middle folding arm 26 of the toilet lid opening pedal 13a that has been extended operates to bend, and the toilet lid opening pedal 13a that has been stepped down moves upward to the original position. When the toilet lid 52 is closed, the electromagnetic clutch 28 does not operate, so that the toilet seat drive shaft 17 and the toilet seat opening pedal 13b do not behave.

Next, the case where the toilet seat opening pedal 13b and the close button 15c of the main operation switch 15A are sequentially operated will be described. In this case, in each case, the electromagnetic clutch 28 operates in a direction for connecting the toilet lid drive shaft 16 and the toilet seat drive shaft 17. That is, when the toilet seat opening pedal 13b is depressed, the center bending arm 26 extends and pushes the toilet seat drive shaft 17 via the small arm 27 (FIG. 3). At this time, the toilet lid drive shaft 16 on the toilet main body 51 rotates together with the toilet seat drive shaft 17 via the electromagnetic clutch 28.
As a result, in addition to the toilet seat drive shaft 17, the toilet lid drive shaft 16
Then, all the members operating with the toilet lid drive shaft 16 operate (FIGS. 4A and 4B), and the toilet lid 52 and the toilet seat 53 simultaneously open. In other words, the opening operation of the toilet seat 53 is premised on the opening operation of the toilet lid 52 on the toilet seat 53. Therefore, when the toilet seat driving shaft 17 is driven, the electromagnetic clutch 28 causes the toilet seat driving shaft 17 and the toilet lid driving shaft When the opening operation of the toilet seat 53 is selected by connecting the toilet seat 52, the toilet lid 52 is naturally opened.

Thereafter, when the close button 15c is pressed, the gear G1 is moved in the direction of the arrow K2 by the motor 21, and the gear G2 meshing with the gear G1 rotates in the direction of the arrow K3 (FIG. 4A). Then, the toilet lid drive shaft 16 and the toilet seat drive shaft 17 connected by the electromagnetic clutch 28 are simultaneously driven to rotate by an equal amount, and the toilet lid 52 and the toilet seat 53 are simultaneously closed. At this time, the gear G2 drives the gear G3 in the direction of the arrow K2, and the rotation of the gear G3 is transmitted through the intermediate shaft 18 to the gear G4.
The gear G4 drives the gear G5 attached to the other toilet lid drive shaft 16 in the direction of the arrow K3. Therefore, the dog 24 attached to the toilet lid drive shaft 16 is indicated by an arrow K.
The displacement is made in three directions, and the limit switch 22 is operated.
The limit switch 22 includes a toilet lid 52 and a toilet seat 53.
Protection function to prevent the excessive force from being applied to various members when the close button 15c is kept pressed despite the closing of the toilet lid 52 and the toilet seat 53 when the closing operation is detected. Plays. In addition, the toilet seat 5 by the motor 21
In the opening operation of 3, the other limit switch 23 takes charge of this function.

In this embodiment, the Western style toilet 50
User selects the opening operation of the toilet lid 52 using the foot pedal 13, and then selects the closing operation of the toilet lid 52, and when the user of the Western-style toilet bowl 50 operates the main operation switch 15A or If the user selects the opening operation of the toilet lid 52 using the remote operation switch 15B and then selects the closing operation of the toilet lid 52, and the user of the Western toilet 50
The case where the toilet seat opening pedal 13b and the close button 15c of the main operation switch 15A are sequentially operated has been described as a representative example. Foot pedal 13, main operation switch 15A,
Although there are other operation methods by the combination of the remote operation switch 15B, even when all the members are operated by the illustrated operation method and the user of the Western-style toilet bowl 50 selects another operation method, it is not changed. This mainly appears as a difference in the rotation direction of the rotation system, and the operations of the various members are in accordance with the above-described operation examples. Regardless of which mode of operation is selected, the user of the Western style toilet 50 gets his hands dirty with one of the foot pedal 13, the main operation switch 15A, and the remote operation switch 15B. The toilet seat 53 and the like can be easily opened and closed without the need.

The opening and closing device 10 for the toilet lid and the toilet seat of the Western toilet 50
Respectively connect the toilet lid arm 36 and the toilet lid 52 via push rods 36e and 37e, and the toilet seat arm 37
And the toilet seat 53 may be connected (FIG. 6). Also in this embodiment, the toilet lid drive shaft 16 and the toilet seat drive shaft 1
7 is output from both shafts, but the casing 11 is designed to have a reduced height. It is assumed that the main operation switch 15A of the casing 11 is omitted, and only a remote operation switch 15B (not shown) is provided. To the toilet lid 52 and the toilet seat 53, clamp fittings 38, 38 each having a pin P2 protruding are attached.
e, 37e are connected to the distal ends of the toilet lid drive shaft 16, the toilet seat drive shaft 17 and the clamps 38, 38 so that both ends thereof can be swung by pins P2, P2,.

In the toilet lid and toilet seat opening and closing device 10 of this embodiment, the operation of the toilet lid arm 36 and the like is controlled by the push rod 36e,
Since it can be transmitted to the toilet lid 52 and the like via 37e,
At the time of installation, the toilet cover drive shaft 16 and the like and the mounting shaft 5 of the toilet cover 52
Since there is no need to bring the foot pedal 4c closer to the position, it is easy to position the foot pedal 13 at a position where it can be most easily used. In other words, the operation of directly driving the toilet lid 52 and the toilet seat 53 by the toilet lid arm 36 and the toilet seat arm 37 is performed for the toilet lid arm 36 and the toilet seat arm 37 also.
3 is also a rotation operation in a certain range having a specific center of rotation, so that when the center of rotation of the driven member and the center of rotation of the driven member do not match, a smooth operation is not ensured. When the push rods 36e, 37e are interposed between the arm 36, etc. and the toilet lid 52, etc., only the vertical displacement component of the rotation operation of the toilet lid arm 36, etc. is transmitted via the push rods 36e, 37e. The rotation operation itself of the toilet arm 36 and the like is transmitted to the toilet lid 52 and the like.
Thus, there is no need to bring the toilet lid drive shaft 16 or the like, which is the center of rotation of the toilet lid arm 36, etc., and the mounting shaft 54c, which is the center of rotation of the toilet lid 52 or the like, close to each other. In addition to this, the casing 11 can be reduced in size, and the opening degrees of the toilet lid 52 and the toilet seat 53 can also be improved by the push rod 3 with respect to the toilet lid arm 36 and the toilet seat arm 37.
It can be easily adjusted by changing the attachment positions of 6e and 37e.

As described above, in the embodiment of the present invention,
Although the toilet lid drive shaft 16 and the toilet seat drive shaft 17 have a double-shaft structure, they may be adjacent independent shafts. This is because the toilet lid 52 and the toilet seat 53 may be attached to different shafts depending on the Western style toilet 50. Further, although the toilet lid drive shaft 16 is separated to the left and right, it may be a continuous single shaft. Since the toilet lid drive shaft 16 and the toilet seat drive shaft 17 rotate within a predetermined angle range, even when the toilet lid drive shaft 16 is a single shaft, the toilet seat drive shaft 16 is partially cut out to enable the toilet seat drive shaft 16 to rotate. This is because a small arm can be attached to the shaft 17. Thus, by this, the intermediate shaft 18 and the gears G3, G4, for transmitting rotation between the toilet cover drive shafts 16, 16 in the separated state.
G5 can be omitted. Also three foot pedals 1
The support shaft 19 for three may be an independent shaft for each foot pedal 13 instead of a common shaft. Each foot pedal 13
Since the functions assigned to them are different, the vertical position and the bending angle of the center bending arm 26 can be set optimally for each foot pedal 13 by making the support shaft 19 independent. Note that a waterproof blind cap is provided on the shaft ends of the unused toilet lid drive shaft 16 and the toilet seat drive shaft 17 that are output from both shafts. The same applies to the socket 15f when the remote operation switch 15 is not used.
