Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a toilet seat lifting device for a Western-style toilet bowl.

(Prior Art) Generally, a so-called Western-style toilet bowl has an annular toilet seat with a cover on the top. A toilet seat must be used when defecating or when a woman urinates, but it is not necessary when a man urinates.

By the way, conventional toilet seats are designed to be simply held up by hand.

(Problems that the invention aims to solve) If the toilet seat is simply held and lifted by hand, as with conventional toilet seats, it may lack cleanliness when used in public restrooms in stores, companies, hospitals, etc. . In addition, since the user has to lift the robot in a bent-down position, it may be painful for people who complain of lower back pain.

The present invention attempts to solve the above problems.

(Means for Solving the Problems) The toilet seat lifting device of the present invention consists of a first arm, a second arm, and a support stand provided on the side of the toilet, and the first arm has one end. It is fixed to the toilet seat by wrapping a sliding band or string around a part of the toilet seat and tightening it, and extends generally downward,
the other end is rotatably connected to one end of the second arm,
A knob is provided at one end of the second arm, the second arm extends forward generally horizontally, a foot pedal is provided at the other end, and protrusions perpendicular to the arm are provided at both ends of the approximately intermediate portion. The support base has a top-opening guide groove that extends back and forth, and a top-opening bearing groove that is perpendicular to the guide groove in the middle of the guide groove, and the second arm is fitted into the guide groove from above. At the same time, the protrusion is fitted into a bearing groove from above and rotatably supported on a support base, and when the pedal is depressed, the second arm and the first arm are linked to lift the toilet seat. It is characterized by this.

(Function) When the pedal is depressed, the second arm rotates about the rotation fulcrum, and the toilet seat is lifted up via the first arm.

(Example) In FIG. 1, a stand 11 is made of ceramic, for example, and is fixed to a toilet floor 12 using double-sided tape or tile adhesive. A bearing groove 13 that extends perpendicularly to the plane of the paper and is open upward is formed at the upper end of the table 11, and a guide groove 14 that extends parallel to the plane of the paper and is shallowest at the middle part.
is formed. An intermediate portion of a second arm 15 extending generally horizontally is inserted into the guide groove 14, and a second
A fulcrum shaft 16 protruding from the arm 15 in both directions perpendicular to the plane of the drawing is rotatably fitted into the bearing groove 13.

A pedal 17 is attached to one end of the second arm 15. For example, concrete or iron is placed inside the pedal 17, which also serves as a weight for balance. The other end of the second arm 15 is connected to the lower end of the first arm 19 via a bolt 18 extending perpendicular to the plane of the drawing.

The first arm 19 extends generally in the vertical direction, and the second
As shown in the figure, a sliding band 21 is attached to the upper end by a bolt 20 rotatably supported.
is installed. Band 21 is an annular toilet seat 2
2 and is fixed to the toilet seat 22 by being tightened. A knob 23 is attached to the other end of the bolt 20.

Note that the members other than the stand 11 are made of aluminum or stainless steel to prevent rust. Moreover, the present device is more specifically installed as shown in FIG. In FIG. 3, 31 is a toilet bowl, 32 is a cover, and 33 is a water tank.

Next, the operation will be explained. In FIG. 3, when the pedal 17 is depressed, the second arm 15 rotates about the fulcrum shaft 16 in FIG. 1, and the first arm 19 is lifted upward. As a result, the toilet seat 22 is lifted together with the cover 32 as shown in FIG. 4, and by further depressing the pedal 17, the toilet seat 22 assumes the posture shown in FIG. 5, and becomes the normal lid open state. In this state, even if the foot is removed from the pedal 17, the open state is maintained.

When closing the toilet seat 22, press the knob 23 (first
(Fig.) with your hands. Since there is no need to touch the toilet seat 22, it is more hygienic.

The above operation can be performed in the same way even when the cover 32 is in the raised state from the beginning.

When cleaning the toilet, etc., first lift the second arm 15 in the direction A from the state shown in FIG. 5, pull out the fulcrum shaft 16 from the bearing groove 13 shown in FIG.
5 on the first arm 19. Furthermore, the overlapping second arm 15 and first arm 19 are connected with a bolt 20 (second
(Fig.) in direction B and tilt it toward the water tank 33 side. As a result, all the members other than the table 11 are placed above, so that they do not get in the way of cleaning.

It should be noted that if the weight of the pedal 17 is appropriately set and balanced, the toilet seat 22 can be opened and closed easily and smoothly.

(Another example) A string may be used instead of the band 21.

(Effect of the invention) The first arm 19 and the second arm provided on the side of the toilet bowl
The first arm 19 consists of an arm 15 and a support base 11, and the first arm 19 has one end fixed to the toilet seat 22 by wrapping a sliding band 21 or a string around a part of the toilet seat 22 and tightening it, and extending generally downward. The end is rotatably connected to one end of the second arm 15,
A knob 23 is provided at one end, the second arm 15 extends forward and generally horizontally, a foot pedal 17 is provided at the other end, and protrusions perpendicular to the arm 15 are provided on both sides of the approximately middle portion. (fulcrum shaft) 16, and the support base 11 has an upwardly opening guide groove 14 extending back and forth, and a guide groove 1 in the middle part of the guide groove 14.
The second arm 15 is fitted into the guide groove 14 from above, and the protrusion 16 is fitted into the bearing groove 13 from above to rotate to the support base 11. The toilet seat 22 is freely supported, and when the pedal 17 is stepped on, the second arm 15 and the first arm 19 are linked to lift the toilet seat 22, so the following effects can be expected.

(a) It is clean because the toilet seat 22 can be opened without using hands.

(b) Hygienic, especially when used in public toilets in stores, companies, hospitals, etc.

(c) Since there is no need to bend down, it can be easily operated even by people who complain of lower back pain.

(d) It is convenient for men when they are in a hurry, and it is also convenient for women because there is less chance of the toilet seat 22 being soiled.

(e) Since there is no need to change the structure of the conventional toilet bowl, it can be easily adopted and is low cost.

(f) One end of the first arm 19 is fixed to the toilet seat 22 by wrapping a sliding band 22 or string around a part of the toilet seat 22 and tightening it.
For this reason, one end of the first arm 19 of a constant length can be fixed even to toilet bowls in which the height positions of the toilet seat 22 are different. Therefore, the device of the present invention can be flexibly attached to various toilet bowls and has a high degree of freedom. Moreover, since only the band 22 or string is attached to the toilet seat, the cover 32 does not get in the way when the toilet seat 22 is covered with the cover 32.

(g) The second arm 15 is rotatably supported by the support base 11 by fitting into the guide groove 14 from above and fitting the protrusion 16 into the bearing groove 13 from above. Therefore, when performing cleaning or the like, the second arm 15 can be easily lifted upward and removed from the support base 11 without using any tools. Therefore, in the device of the present invention, by stacking the second arm 15 with the first arm 19 and lifting it further up, all the members other than the support base 11 can be placed upward, so that they do not get in the way during cleaning etc. This is particularly effective for cleaning narrow toilet floors.

(h) The second arm 15 is supported by the support stand 11. That is, only the support stand 11, which occupies a small area, is fixed to the floor on the side of the toilet bowl. Therefore, when cleaning etc.
The percentage of interference is small. Therefore, the device of the present invention can prevent the device from becoming a hindrance during cleaning or the like in this respect as well.

(i) The second arm 15 is supported by the support base 11 with the protrusion 16 fitted into the bearing groove 13. Therefore, even if the pedal 17 is stepped on unevenly, the arm 15 will not be twisted due to the presence of the protrusion 16, and failures due to twisting of the second arm 15 can therefore be prevented.

(j) Since a knob 23 is provided at one end of the first arm 19, when it is desired to close the toilet seat 22 or open/close the toilet seat 22 manually, the user can hold the knob 23. Therefore, since there is no need to touch the toilet seat 22, it is possible to prevent hands from becoming unclean.

(k) The second arm 15 is fitted into the guide groove 14 and supported by the support base 11. Therefore, the second arm 15 vertically moves up and down along the guide groove 14. Therefore, the first arm 19 can be reliably raised vertically, and the opening operation of the toilet seat 22 can be reliably performed.
