Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat structure for a toilet bowl installed in a home, a business office or the like.

[0002]

BACKGROUND OF THE INVENTION Generally,
If this is a Western-style toilet, the toilet seat supports the toilet seat so that it can swing up and down, and the toilet seat is used with it raised. For men's urine, and the toilet seat is moved downwards to sit on it. It is possible to switch to other types of toilets. However, in the conventional toilet seat, each user had to manually swing up and down. For this reason, it is difficult to swing the toilet seat up and down one by one when it is necessary to take care of the infant or when handicapped by a physically handicapped person. It is often the case that there is a desire to eliminate this.

[0003]

SUMMARY OF THE INVENTION The present invention has been devised with the object of providing a toilet seat structure in a toilet bowl that can eliminate these drawbacks in view of the above-mentioned circumstances. In a toilet bowl that supports a toilet seat to swing up and down, the swing support portion of the toilet seat is provided with a swing drive portion for automatically swinging the toilet seat.

According to the present invention, the toilet seat can be automatically swung up and down.

[0005]

An embodiment of the present invention will be described below with reference to the drawings. In the drawings, reference numeral 1 denotes a toilet body installed in a toilet, and the upper end of the toilet body 1 has a front end of a substantially horseshoe-shaped toilet seat 2 which is swingable up and down via an output shaft 9 described later. It is supported so that it can be switched between men's urine which is used with the toilet seat 2 moved up and other urinals which are used by lowering the toilet seat 2 and sitting there.

Reference numeral 4 denotes a swing drive section, and the swing drive section 4
The casing 5 constituting the above is integrally fixed to the toilet body 1 by an appropriate fixing means such as a screw. The casing 5 has a drive motor 6 and the power from the drive motor 6 is reduced. A reduction gear mechanism 7, an output shaft 9 that is motive power transmitted to a final gear 7a of the reduction gear mechanism 7 via a torque limiter 8, an operating arm 10 having a proximal end integrally fixed to the output shaft 9, and an output. Limit switch 1 for upper limit and lower limit that opens when shaft 9 is at the upper limit position and the lower limit position, respectively.
The operating arm 10 is integrally fixed to the toilet seat 2 via a fixing means such as a screw.

Next, a drive circuit in the case where a DC motor is adopted as the drive motor 6 will be described with reference to FIG. This circuit includes a transformer 1 that transforms the AC power supply 100V into a required voltage.
3. A rectifier 14 for rectifying the transformed AC power source to a DC power source is provided, which allows the DC power source of the drive motor 6 to be obtained. SW is a hand switch arranged at a position where it can be easily operated, such as a wall of a toilet. The hand switch SW is wired so as to be drawn out from the power supply circuit. The circuit to which the contact SWU is connected includes a rising relay switch RU and the upper limit limit switch LSU.
, And the descending side contact SWD is connected to the descending relay switch RD and the descending limit switch LSD. On the other hand, the power supply circuit to the drive motor 6 includes a relay switch R for raising and lowering.
U and RD switch contacts are connected, but these switch contacts RU and RD are the corresponding relay switches R.
RU2, RD2 in the non-excited state where U and RD are not energized
RU1 and R in the energized state with conduction to the contact on the side
It is set to conduct to the contact on the D1 side. When the hand switch SW is operated so that the ascending side contact SWU is closed to energize the ascending side relay switch RU, the contact point RU1 of the ascending side relay switch RU is energized. With respect to the switch contact RD of the descending side relay switch, the contact RD2 side remains energized, whereby the DC power source from the rectifier 14 is contact A, contact RU1, drive motor 6, contact RD2, contact B,
The electric current flows through the contact point C, so that the output shaft 9 of the drive motor 6 rotates to the upper limit position and the upper limit switch LS.
Until the U is opened, it will be driven to raise the toilet seat 2. On the other hand, turn the hand switch SW to the descending contact S.
Operate to the side where WD is closed, and lower side relay switch RD
When the switch relay RD of the descending side relay switch is energized on the contact RD1 side, the switch contact RU of the ascending side relay switch remains energized on the contact RU2 side. The DC power from 14 flows in the opposite direction to the above via the contact A, the contact RD1, the drive motor 6, the contact RU2, the contact B, and the contact C, and thus the drive motor 6 has the output shaft 9 It is set so as to drive and lower the toilet seat 2 until the lower limit switch LSD is rotated backward to the lower limit position and the lower limit switch LSD is opened.

In the embodiment of the present invention constructed as described above, when the toilet user in the toilet is a man who urinates, when the toilet seat 2 is descending, the hand switch SW is turned up. When operated, the drive motor 6 is driven to raise the toilet seat 2 automatically as described above.
Further, in the case of using a toilet other than the above, when the toilet seat 2 is raised, if the hand switch SW is operated to the lower side, the drive motor 6 is reversely driven and the toilet seat 2 is automatically lowered. ..

As described above, in the embodiment of the present invention,
Since the toilet seat 2 can be automatically raised and lowered by the forward and reverse driving of the drive motor 6, when the infant needs to be stool, the toilet seat 2 must be taken care of by the infant, When a person with a disability needs to use the toilet, it is not necessary to manually lift or lower the toilet seat 2 as in the conventional case, and it can be automatically performed only by a switch operation of the hand switch SW. There is no forced work.

Moreover, in this one, the reduction gear mechanism 7
Since the final gear 7a and the output gear 9 are interlocked with each other via the torque limiter 8, it seems that the hand switch SW is mistakenly operated to the ascending side with the toilet seat 2 lowered and sitting down. Even in this case, the electric motor 6 will not be overloaded. Incidentally, there is a problem that the electric motor 6 continues to be driven in this device, and therefore, a circuit of the hand switch SW is provided with a timer switch which is activated by energization based on a closing operation of either raising or lowering the hand switch SW, If the circuit of the hand switch SW is energized for the set timer time (of course, this timer time is set to a time longer than the time required for the toilet seat 2 to move up and down), the above problem will occur. It never happens.

The present invention is not limited to the above-mentioned embodiment, but may be any one provided with a swing drive section for automatically swinging the toilet seat. In that case, the drive switching of the swing drive unit is not limited to the hand switch, but may be a foot switch capable of switching the drive by stepping on with a foot, and further, these switching operation switches, It may be a rotary type switch that sequentially switches up and down, or it may be a push button type that automatically resets the switch itself, and the switch contacts of each relay switch should be connected to the switch contacts of the switching operation switch in order to maintain the push operation. You may connect in parallel. Furthermore, in the above-described embodiment, the swing support shaft of the toilet seat is used as the output shaft of the swing drive unit, but the present invention is not limited to this, and the swing support shaft of the toilet seat and the output shaft are separately provided. It may be configured as. In that case, there is a structure in which the swing support shaft and the output shaft are arranged so as to coincide with each other, and a structure in which they do not coincide with each other. Need not be provided, and the output shaft may be configured to be directly connected to and supported by the toilet seat. In the latter case, for example, a long hole may be formed at the tip of the operating arm to A support pin integrally provided on the toilet seat side is movably engaged with the hole so that the support pin can vertically swing based on the swing of the operating arm by allowing the support pin to move through the long hole. It is possible to configure the present invention, and in such a case, there is an advantage that the present invention can be directly applied to the existing toilet seat.

[Operation and Effect] In short, since the present invention is constructed as described above, when the user raises or lowers the toilet seat according to the application such as urine or stool, This can be done automatically without having to operate it by hand. For example, when you need to take care of an infant, when you can't let go of the care of the infant or when a person with a physical disability uses it. Sometimes it is convenient to lift and lower the toilet seat by hand, unlike in the past, and to avoid forcing an uncomfortable posture.
