Description

Automatic opening and closing device of the toilet seat {Automatic Lift for Toilet Seat}

The present invention relates to an automatic opening and closing device of the toilet seat is a device that can stand up or seat the toilet seat without directly touching the toilet seat hinged to the toilet seat body. Specifically, after the toilet is used, the stopper connected to the hydraulic cylinder (straight or rotating) of the pressure switch is connected to the hydraulic cylinder (straight or rotating) by using the change in the hydraulic pressure generated during the flushing and rewatering of the toilet bowl. By disengaging, the toilet seat is automatically rotated and fixed upright by the return elastic force of the torsion spring hanging on the toilet seat hinge rotation axis.When using the toilet seat, press the movable seat pedal located on the floor near the toilet once. , The toilet seat is rotated down and seated on the upper surface of the toilet bowl can be used fixed.

The toilet seat of the present invention is always kept in an upright state while the toilet bowl is opened by the elastic force of the torsion spring mounted on the seat hinge rotation shaft coupled to the toilet body. Thus, when anyone uses the toilet seat, gently press down the mobile seating pedal located near the toilet seat, so that the pedal pulls the tube wire to rotate the hinge axis of the toilet seat and the toilet seat rotates and rests on the bowl bowl. Is inserted into the locking groove in the toilet seat hinge rotation axis, thereby seating and fixing the toilet seat. The toilet seat is fixed in the seated state as the stopper is inserted into the catching groove while the torsion spring is rotated in the reverse direction while generating the return elastic force in the spring while rotating downward from the upright state to the seated state. This stop is connected to the hydraulic cylinder (straight or rotary) of the pressure switch attached to the water supply pipe so that when the hydraulic pressure is maintained in the hydraulic cylinder of the pressure switch, the piston always moves forward to push the stopper into the catch groove. Get hit. Then, by pressing the flush lever of the reservoir tank or the compressed tank toilet, the toilet bowl is flushed by releasing the toilet tank or the toilet washing water already stored in the compression tank. Alternatively, as the valve of the water supply controller in the compression tank is opened and re-watered, the water pressure in the water supply pipe drops. When the water pressure in the pipe drops, the pressure drops to the hydraulic cylinder of the pressure switch attached to the water main pipe and the reservoir tank, or the water supply pipe connecting the compression tank, and the pressure also drops to the advanced piston. When the pressure drops in the cylinder (straight or rotating) seal, the piston retracts to its original position by the restoring force of the tension spring attached to the piston front, and the stop wire connected to the tube wire also retracts from the locking groove. As soon as the stopper is released from the locking groove, the toilet seat is reversely raised to its original position by the return elastic force of the torsion spring held on the hinge rotating shaft of the seat coupled to the toilet body, and fixed in an upright state. The functional form in the pressure switch is not limited to linear cylinders or rotating cylinders, but includes all mechanical devices capable of pushing and pulling a stop connected to it, depending on the presence or absence of hydraulic pressure. Accordingly, the basic spirit of the present invention is a suitable device of a pressure switch, and is not limited to the use of a device of a specific function, and any method of advancing or reversing the stop connected to the pressure switch in accordance with the change in the water pressure can be accommodated.

Background of the Invention

When using the toilet in the restrooms of homes and public spaces until now, there was a discomfort that the toilet seat is dirty first, and the hands must be touched with the dirty parts. Most toilet seats rest on toilet bowls. For example, when a man is pissing, if the toilet seat is in an upright position, it may be necessary to just piss and flush the toilet bowl. However, when the toilet seat is horizontally seated on the toilet bowl, most men do not want to touch the toilet seat by hand, so it is common to pee in that state. In this case, part of the excrement inevitably falls on the upper surface of the toilet seat and is buried in the toilet seat. Then, you have to leave the toilet after leaving the toilet, such as cleaning the toilet seat, it is well known that most users leave it as it is. If a man or woman is to sit on the toilet seat in the following order, it is not unpleasant and uncomfortable, such as cleaning the toilet seat first before seeing the work. In addition, even if the toilet seat is settled horizontally on the toilet bowl without any mess, the next user's general sentiment is that toilet seats are toilet toilet seats in the imagination that all of the user's urine drops will splash or dirt marks somewhere on the toilet seat. It is common practice to clean and use. In another example, when using the water in a wash basin or bathroom in a bathroom, if the toilet seat is flat, the water will splash on the top of the seat, so you need to clean it again later. In view of the above situation, toilet seats of toilets normally, when left in the toilet seat horizontally seated in the toilet seats, the man is pissing in the toilet seat as it is, and the surrounding foreign objects may splash and get dirty. Therefore, even when men or women use toilet seats, they do not feel uncomfortable, and the toilet seats are washed and used as toilet paper, which causes unnecessary labor and material waste. Therefore, it is advisable to keep the toilet seat upright at all times, but even in this case, when the male or female uses the toilet seat and lowers it, the unpleasant objection that the toilet seat should be placed horizontally on the toilet bowl by hand contact with the toilet seat is maintained. You have to take it. In view of the above circumstances, everyone would have expected the emergence of a new toilet seat that can be used cleanly, hygienicly and comfortably.

It is an object of the present invention to complement the above-mentioned closures by means of device, regardless of gender, young and old, when anyone uses the toilet in the home or public places, it is more economical automatic opening and closing, more clean, hygienic, simple and convenient for everyone To provide a toilet seat.

Purpose of the Invention

The purpose of the present invention is to ensure that the toilet seat is always fixed upright and the toilet seat is automatically rotated down by pressing the seat pedal once when the toilet seat is used, and the seat is fixed to the toilet bowl. It is an object of the present invention to provide a technical device in which the toilet seat is rotated up and fixed upright in its original position.

The technical field to which the invention belongs and the prior art in that field

The present invention relates to an automatic opening and closing device of the toilet seat, the elasticity of the spring, the return elastic force, the change in the water pressure of the water supply pipe to which the toilet water is supplied, the operating principle of the pressure switch accordingly, the pedal switch and the tube wire, etc. The seat is always fixed upright, and when using the toilet seat, by pressing the foot pedal on the floor once, the toilet seat that was fixed upright is automatically rotated and lowered to be horizontally seated on the toilet bowl top surface. By discharging the toilet wash water after use, the toilet seat is automatically rotated up and held in its original upright position.

A more hygienic, clean, and convenient way to use the toilet seat without touching the hand has been studied for a long time, both East and West, and several devices have been developed and presented. However, all the devices are uniformly unified so that they have not been brought to practical use. For example, if you analyze the "Public Patent Publication" of the Republic of Korea, one thing is that the hinge part of the toilet seat is simply mounted with a rotating spring, so that it is always upright. It is inconvenient to use because it is necessary to press the toilet seat and seat the buttocks, and in other cases, the toilet seat size and the means of raising the toilet size is made of a pedal that is fixed to the toilet body. It is possible to use the legs, not the ankles, because the distance is long, and even when men are urinating, they have to press the pedals to fix the toilet seat upright. . Another thing is to press the pedal with your foot by using hydraulic or hydraulic pressure to inflate the pressure in the lake and move the lever or inflate the bellows, or the other, to lift the toilet seat. As it is executed in a seated situation, when men are pissing, there is a possibility of pissing the toilet seat without leaving it in the toilet bowl.In addition, even if the pedal seat is lifted and the toilet seat is lifted, the pedal is kept pressed with the foot even if the toilet seat is pushed. By doing this, the posture is inconvenient, this is also not a convenient way. Therefore, the present inventors analyze and analyze the disadvantages of the opening and closing device as described above, to develop a toilet seat automatic opening and closing device of the latest construction method that can be easily used by everyone, regardless of gender, young and old, clean and hygienic.

As a technical problem for completing the present invention, by mounting a torsion spring on the hinge portion of the toilet seat coupled to the toilet body by appropriately elastic in an upright state, the toilet seat should be always upright fixed. When the toilet seat is rotated down in the upright position and is horizontally seated on the toilet bowl, the return elasticity generated by the rotating spring mounted on the hinge portion of the toilet seat is smoothly reversed without impact or noise until the toilet seat itself is fixed upright. It must have a value of return elastic force that can be achieved. In order to satisfy the above conditions, the toilet seat hinge should be equipped with an adjustment knob to appropriately adjust the return elastic force of the spring. A pedal is used to horizontally seat the toilet seat fixed to the toilet bowl. The front end of the tube wire is joined to the crimping part of the pedal, and the rear end is joined to the wheel part of the hinge rotation shaft of the toilet seat to press the tube. The wire is pulled and the toilet seat rotates about the hinge axis of rotation as the opposite end of the wire winds one or more turns around the wheel of the hinge axis of the toilet seat. The pedals are spring loaded to prevent loosening of the tube wires to maintain proper inflation force. And the toilet seat is rotated in an upright position to make a locking groove in a portion of the hinge rotation axis of the angle that is horizontally seated on the upper surface of the toilet bowl is equipped with a stop that can be inserted into this locking groove, and inserted into the locking groove Install and fix the stopper supporting the stopper. Thus, in the position where the toilet seat rotates down in an upright position and is horizontally seated on the top of the toilet bowl, the hydraulic cylinder (straight or rotary) of the pressure switch of the water supply pipe continues to advance the stop so that the stop is inserted into this locking groove. And the toilet seat is fixed in a seated state. When the toilet seat is automatically turned upside down, it is most suitable for the user to discharge the toilet water after the toilet is used. Therefore, install a pressure switch in a water supply pipe for supplying water to the reservoir tank or the compression tank. The hydraulic pressure cylinder (straight or rotating) is built into the pressure switch, so that water pressure is always generated in a situation where water does not flow, so the piston is continuously pressurized while advancing. In addition, a tension spring of a suitable elasticity is built into the rear surface of the piston, and when the hydraulic pressure decreases, the piston moves backward by the return elastic force of the spring. At this time, the elastic force of the tension spring should be weaker than the water pressure. Function types within the pressure switch include, but are not limited to, linear or rotary cylinders and all mechanical devices capable of pushing and pulling the stop connected to it, depending on the presence or absence of water pressure. Accordingly, the basic spirit of the present invention is a suitable device of a pressure switch, and is not limited to the use of a device of a specific function, and any method of advancing or reversing a stop connected to the pressure switch may be accommodated according to the change in the hydraulic pressure. . One side of the tube wire is connected to the back of the pressure switch, and the other side of the wire is connected to the stop so that the toilet seat hinge pivot can be caught depending on whether the pressure switch's hydraulic cylinder (straight or rotary) is operating. The stopper inserted into the groove controls the increase in rotation of the toilet seat while repeating forward or backward. By overcoming the above technical problems, the toilet seat automatic opening device will be an invention exhibiting excellent performance.

Hereinafter, the operation and function of the present invention will be described in detail with reference to the accompanying drawings.

In the toilet seat unit of the present invention, the toilet seat 6 and the lid 7 are hingedly coupled, but there is no dynamic relationship between the two parts, and the sewage of the toilet is clogged so that the soil is not washed and the toilet bowl 1 is not flushed. When left, it is a means of covering the toilet bowl 1 so that the dirty shape is not exposed. Therefore, the cover 7 is always kept in the upright state of the obtuse angle from the bowl 1 at ordinary times. On the left side of the rotary hinge half (Fig. 4u) of the toilet seat 6, the lift operation part 4 is provided. The torsion spring 44 is mounted in the lift operation part 4, the front end is joined to the spring elastic adjustment knob 42, and the rear end is joined to the hinge portion integral with the toilet seat 6. The spring resilient adjustment knob 42 rests on the toilet seat 6 while the toilet seat 6 is seated on the toilet bowl 1, and after use of the flushing levers 11 and 9, the spring seat 6 adjusts to a position where the toilet seat 6 itself is fixed upright. The return elastic force of the torsion spring 44 is variably adjusted and fixed so that the rotation can rise smoothly without noise. The torsion spring 44 of the toilet seat 6 which is thus fixed and fixed provides a suitable elastic force so that the toilet seat 6 is always fixed in an upright position, without applying any physical force from the outside. Normally, when the toilet seat 6 is kept open in an upright position, as an example, when men are urinating, they may simply urinate and flush the water without having to contact the toilet seat 6. Since the toilet seat 6 is in an upright state, no matter how the urine drops, the toilet seat 6 will not need to be cleaned, since there will be no reason for it to stick to the toilet seat 6. In addition, even when the toilet seat 6 is in an upright position, even when the water pressure switch 2 (FIG. 3u) operates by lowering the flush levers 11 and 9 to discharge the washing water, the toilet seat 6 has no effect. Do not. As a second example, when a man or a woman uses the toilet seat 6, the toilet seat 6 standing upright is rotated downward by pressing down on the seating pedal 10 placed on the floor around the toilet 1. It is seated in 1) and is fixed. The front end of the tension tube wire 20 is joined to the pedal 10, and the rear end thereof is fixed to the wire of the lowering operation part (Fig. 5ua), which is the right end of the toilet seat 6 hinge half (Fig. 5u), with a predetermined length. It is rotationally joined to the drum 38 (FIG. 5U-S). Thus, when the pedal 10 is stepped on, the pedal upper plate rotates and the tube 38 of the lowering control unit (FIG. 5ua) connected to it pulls the tube wire 20 while maintaining the angle in the pedal 10 while making the wire declination. ) Rotates, and the toilet seat (6), which is integrated with the drum (38) and the hinge fixing shaft (31), is rotated downward and seated on the toilet bowl (1). By moving the torsion spring 44 mounted in the lift actuator 4 ua of the toilet seat hinge half (Fig. 4u) in the reverse direction while rotating downward, the torsion spring 44 causes itself to generate the return elastic force as much as it has been moved. do. The fact that the torsion spring of the upward actuating portion of the rotary hinge half (Fig. 4u) of the toilet seat (6) had a return elastic force as much as it was originally suggests that the toilet seat (6) integral with this rotary hinge half (Fig. 4u) is in its original position. It can be said that it has the resilience to return itself to the upright state. Moreover, the hinge fixing shaft 31 comprised in the lift control operation part (FIG. 4ua) installed in the toilet seat 6 hinge half (FIG. 4U) in the position where the toilet seat 6 is seated in the toilet bowl 1 is shown. The stopper 33 of this operating part (FIG. 4 uap) is inserted into the engaging groove 36 of the drum integrated in the (). Since the angle of the catching groove 36 of the drum into which the stopper 33 is inserted is the seating angle of the toilet seat 6 integrated with this, the position of the stopper 33 and the catching hole 36 of the drum should be straight. . The stop 33 of the lift control actuating part (Fig. 4ua) in the toilet seat hinge half (Fig. 4u) is joined with the front end of the tube wire (Fig. 4uap), and the rear end thereof has a suitable length and a hydraulic pressure switch (Fig. 3u). The water tank 5 is connected to the piston 24 of the water supply port through the water pressure switch 2 (FIG. 3U) connected to the water supply pipe 5 of the water storage tank 5 or the compression tank 8. B. Water does not leak toward the compression tank 8, the water pressure expands and pushes the cylinder 25, and the piston 24 joined to the flat membrane portion of the rubber corrugated cylinder 25 continues to move forward. Since the wire of the tube wire 21 joined thereto has a pressing force to continuously push the stop 33 connected to the rear end of the tube (Fig. 4 uap) with the wire as a support for the tube tube in the tube, so that the toilet bowl As soon as the seat 6 is seated in the toilet bowl 1, the stop 33 is inserted into the catch groove 36 of the drum. The toilet seat 6 is inserted into and fixed to the upper surface of the toilet bowl 1.

Finally, when the toilet seat 6 is finished using, it rises up and presses the flush levers 11 and 9 to discharge the toilet washing water, which is already stored in the reservoir tank 5 or the compression tank 8, to flush the toilet bowl 1 At the same time, the washing water is discharged and at the same time the valve of the water supply controller in the water storage tank 5 or the compression tank 8 is opened again to supply water, and the water pressure in the water supply pipe drops. When the water pressure in the pipe drops, the piston 24, which has advanced while the water pressure drops to the hydraulic cylinder (Fig. 3u) of the pressure switch 2 connected to the water supply pipe of the water storage tank 5 or the compression tank 8, Pressure drops. When the pressure drops in the hydraulic cylinder (Fig. 3u) chamber, the tension spring 23, which is attached to the front of the piston 24 and squeezed against the piston 24 due to the hydraulic pressure, is applied to the piston 24 by its restoring force. Push it back to its original position. The front end of the piston 24 is joined to the front end of the tube wire 21 (Fig. 3u), and the rear end is joined to the stop 33 (Fig. 4uap). The stopper 33 also retracts from the drum catching groove 36 to be completely removed. The tension spring 23 suitable here is weaker than hydraulic pressure and must have an elastic force capable of attracting the stop 33. As soon as the stop 33 is disengaged from the catch groove 36, the toilet seat 6 is mounted on the spring actuating part (left part of Fig. 4ua) of the lift control part (Fig. 4ua) coupled to the toilet body 1. The torsion spring 44 is rotated up by the return elastic force retained by the original position and held upright at the original position. And the functional form of the pressure switch 2 is not limited to a linear cylinder (FIG. 3u) or a rotating cylinder, and includes all the mechanical devices which can push and pull the stop 33 connected to it with or without water pressure. Therefore, the basic spirit of the present invention is a suitable device of the pressure switch 2, and is not limited to the use of a mechanism of a specific function, and it is possible to advance or reverse the stop 33 connected to the pressure switch 2 in accordance with the change in the water pressure. Any method that can be accepted is acceptable.

The present invention has been studied to thoroughly analyze the toilet habits, to use the toilet more clean, hygienic and comfortable, and in particular, the toilet seat is automatically rotated up and down at the moment necessary, regardless of the user's consciousness, fixed upright By doing so, the problem that occurs during unauthorized pissing of men was fundamentally solved, and the user was allowed to use the toilet without touching his hand, so that he could use the toilet with a more comfortable mood.

As can be appreciated from the above description, it is not doubted that the present invention will contribute to our clean toilet culture to some extent, and furthermore, it is thought that there is a possibility to develop into an excellent item that can be exported abroad.
