Toilet seat opening and closing device {Hands-free toilet seat lifting up and down device}

.

When men urinate using the toilet, they have to lift the toilet seat with their hands first and then unzip the pants with their hands, which is cumbersome. If the toilet is not cleaned properly, it is very reluctant to touch the toilet with your own hands. something to do. Thus, men may sometimes be contaminated by urinating the toilet without raising it. The purpose of this mechanism is to provide a way to open and close the toilet seat without using the hands directly.

This machine is a device that lifts the toilet seat easily by stepping on the pedal with your feet without using any hands, and pushes the pedal down again after urination.

Using this mechanism, the pants can be unzipped by hand and the pedal can be opened by foot to save time and hygiene. In addition, the external structure is simple, the user can directly install in the existing toilet.

This machine is largely composed of body part, vertical motion bar part and pedal bar. For convenience of explanation, the front, rear, left and right position indication of each part is indicated based on the view of the machine from the front.

1 and 9, the upper part of the body (1) is fixed to the left toilet through the connecting rod (2), loosen the female screw of the screw fixing the existing toilet seat to the toilet bowl body and the male screw hole of the connecting rod Insert it into (3) and fasten it again by tightening the female screw. As shown in FIGS. 1 and 2, the lower part of the body 1 has a body height adjusting device 4 composed of an upper female thread 4a and a lower male thread 4b, and the lower male screw 4b is rotated to wash the toilet. Adjust the height of the body (1) to fit the floor height is fixed. As shown in (a) and (b) of FIG. 8, the toilet and the toilet seat connecting ring 5a or 5b are fixed to one side of the bottom of the existing toilet chair by screwing the toilet seat. The protrusions 6a or 6b of the chair connecting ring may be inserted into the holes of the chair connecting ring guide bar 8 of the upper toilet bowl of the connecting rod 7.

As shown in FIGS. 2 and 3, the body 1 has a movable rod 15, a gear device composed of four gears 11, 12, 13, and 14, a locking device 25, and a guide rod 26. , A vertical motion bar 27 and a shock absorber 30 using a spring.

As shown in (b) of FIG. 4, the release bar 18 is located inside the movable bar 15, and as shown in (a) of FIG. 4, the left side of the movable bar 15 is viewed from the front. Is blocked, and the left side of the inner front portion has a convex surface (凸面) (16) horizontally, the right side of the movable bar (15) is open so that the release bar (18) can enter. When viewed from the front, the left front portion of the unwinding rod 18 has a concave surface 19 horizontally so as to be engaged with the convex surface 16 inside the movable bar 15. As shown in 3), the unwinding rod 18 stably moves back and forth between the movable rod 15 and the first gear 11. As shown in (b) (c) and (d) of FIG. 4, when the release bar 18 is installed in the movable bar 15, the release bar blade 20 located in front of the release bar 18 has a front face. When viewed from the side is more protruding to the left than the moving bar (15). The part protruding to the left side of the release bar blade 20 passes through the guide bar 26 and the remaining right half is a part acting on the locking device 25. As shown in FIGS. 2, 4, and 5, a moving rod return spring 17 for returning the lowered moving rod 15 and the pedal rod 9 to its original position is provided at the rear of the moving rod 15. The body behind the moving rod return spring (17) has a jaw (22) to prevent the pedal rod (9) from being excessively flipped backwards.

As shown in FIG. 2 and FIG. 3, the gear device is composed of four gears meshed with each other. For convenience, the gear surface is shown in a simple circle without expressing in detail. The first gear 11 is not completely circular as shown in the figure, and the restoring device 23 is fixedly attached to the left side thereof. As shown in (c) of FIG. 4, the restoring device 23 has a restoring device blade 23a connected to the restoring device spring 24, and serves to push the release bar 18 back. As shown in FIG. 3, the second gear 12, the third gear 13, and the fourth gear 14 each have two gear surfaces having different radii, and thus the rotation range of each gear is combined. Is amplified. In the radius of each gear, the first gear 11 has a radius of 3.5 cm, the second gear 12 has a small radius of 0.5 cm and a large radius of 2.0 cm, and the third gear 13 has a small radius of 0.5 cm and large The fourth gear 14 has a radius of 1.75 cm and a small radius of 0.5 cm and a large radius of 1.5 cm. The connection of each gear is that the first gear 11 meshes with the small gear surface of the second gear 12, and the large gear surface of the second gear 12 is the small gear of the third gear 13. Meshing surface, the large gear surface of the third gear 13 meshes with the small gear surface of the fourth gear 14, and finally the large gear surface of the fourth gear 14 is It meshes with the gear surface (27a) of the gear device to change the rotational movement of the vertical movement of the vertical bar (27). Considering the size of each gear of the gear device, when the pedal bar 9 is moved at an angle of 5 degrees, the vertical bar 27 is moved about 12.8 cm in a straight line by the gear device.

As shown in the drawing of Fig. 4D, the right half of the locking device 25 is a part of the locking jaw 11a of the first gear, which is fixed in a state in which the vertical movement bar 27 is raised. It is to play a role to keep the toilet seat up. As shown in (d) and (d) of FIG. 4, when the release bar blade 20 passes through the left half of the locking device 25, the locking jaw 11a of the first gear is locked. It is released from (25) and the vertical movement bar (27) is lowered and the toilet seat is lowered.

The guide bar 26 is a portion in which the release bar blade 20 alternates backwards or forwards each time the pedal bar 9 is pressed, as shown in (b) of FIG. 5, the release bar blade 20. When passing to the back of the guide bar 26, the locking device 25 is operated, and as shown in (d) of FIG. 5, passing to the front of the guide bar 26, the locking device 25 is released so that the toilet seat chair is released. Play a role in letting up and down alternately.

The vertical movement bar 27 serves to change the rotational movement of the gear device to the vertical movement of the upper and lower, and as shown in Figure 1, the connecting rod (7) located at the top through the left toilet chair connecting ring guide bar (8) It is connected to the toilet seat connecting ring (5a or 5b) to transfer the vertical movement of the vertical bar (27) to the toilet seat chair. As shown in FIG. 6, since the vertical bar 27 moves in a state of being engaged with the vertical bar support 28 of the body front wall, the vertical bar 27 may move up and down without shaking back and forth. As shown in FIG. 3, the lower right side of the vertical movement bar 27 is connected to the shock absorber spring 30 via the pulley 29 so as to gently lower the toilet seat, and the lower body of the vertical movement bar 27. Sponge pad 31 is located at the bottom to absorb the impact when the vertical movement bar 27 is lowered. As shown in FIGS. 3 and 7 (a), the gear surface 36 on the right side of the vertical motion bar is engaged with the reduction gear 35, and the rotational resistance of the reduction gear 35 is reduced by the reduction gear adjustment screw 10. To adjust the As shown in (b) of FIG. 7, each washer is provided before and after the reduction gear 35, and the front plate 35a of the frame in which the reduction gear is fitted is thin, there is no female screw, and the rear plate 35b is thick and female screw. The male screw 10b of the reduction gear adjusting screw is fitted. When the reduction gear adjusting screw 10 is tightened, the distance between the reduction gear adjusting screw engaging jaw 10a and the rear plate 35b is narrowed, and the thin front plate 35a is pushed backwards to press the reduction gear 35 to decelerate. The rolling resistance of the gear is increased. Therefore, on the heavy toilet seat chair, tighten the reduction gear adjusting screw 10 located on the front of the body 1 to increase the rotational resistance of the reduction gear 35, thereby reducing the force when the toilet seat descends to its own gravity, and the toilet seat chair slowly It can be adjusted to descend.

As shown in FIG. 3, the left side of the upper side of the vertical rod 27 has a protrusion 34 on which the return rod of the vertical rod is caught. After the locking jaw 11a of the gear is released from the locking device 25, the vertical movement bar 27 is pushed down to start the downward movement. In addition, the vertical movement bar return spring 33 absorbs the shock when the vertical movement bar 27 is raised by stepping on the pedal rod 9, thereby simultaneously preventing the left toilet bowl from being hardly hit by the rear toilet bowl. . The vertical motion bar return spring adjustment screw 32 on the upper body adjusts the height position of the vertical motion bar return spring 33 so that the vertical motion bar return spring 33 can be operated at an appropriate position. That is, the locking device 25 is released and the downward movement of the vertical motion bar 27 is started by the vertical motion bar return spring 33, and then the force of gravity due to the weight of the left chair is lowered in order to continue descending the toilet seat without stopping. The toilet seat should be pushed forward to an angle within 90 degrees, which is the position where it can act. Vertical movements can be pushed down to the position in accordance with the situation of toilet seats with different installation environments. It is the vertical movement bar return spring position adjusting screw 32 that allows to adjust the height of the bar return spring 33.

The method of connecting the vertical motion bar 27 to the toilet seat chair is to fix the toilet seat linkage type 1 (5a) to one corner of the toilet seat chair as shown in FIG. After inserting the projection 6a of the connecting ring into the hole of the left toilet seat connecting bar guide bar 8 on the connecting rod 7, the connecting rod 7 may be fixed to the upper end of the vertical movement bar 27. If the floor is a flat toilet seat, as shown in (b) of FIG. 8, the toilet seat linkage type 2 (5b) is connected to the bottom of the toilet seat by screwing and screwing in the same manner. For reference, if a screw cannot be screwed like a chair of a bidet recently used, use a double-sided adhesive tape instead of a screw to fix the toilet seat linkage type 2 (5b) to the bottom of the chair. do.

Since the movement of the vertical movement bar 27 is a linear movement up and down and the opening and closing of the toilet seat is a circular movement, the moving copper lines are different. Therefore, if the connection point of the vertical movement bar 27 and the toilet seat is fixed, even if the vertical movement bar 27 moves up and down, the toilet seat chair does not move properly. In order to solve this problem, if the projection 6a or 6b of the left toilet seat linkage is allowed to move forward and backward in the state of being inserted into the hole of the left toilet seat linkage guide bar 8 located on the upper part of the connecting rod 7, the vertical movement bar When (27) goes up, the protrusion 6a or 6b of the toilet seat linkage moves backward along the hole of the toilet seat link guide bar 8, causing the toilet seat up, and conversely the toilet seat down. When descending, the protrusion 6a or 6b of the left toilet seat linkage moves forward along the hole of the left toilet seat linkage guide bar 8 while lowering the vertical motion bar 27 to open and close the seat.

As shown in FIG. 1, the pedal bar 9 is fixed to each other on the same axis as the moving bar 15 as the site where the operation starts by stepping on the foot and always moves together. Pedal bar (9) is detachable from the body (1) can be installed on either of the left or right side of the body (1) can be installed on the user's convenient side of the left or right of the existing toilet seat. The pedal rod (9) and the body (1) is connected to the waterproofing with a silicone ring.

The principle of operation is as follows. First, Figure 5 (a) shows that the pedal bar (9) and the moving bar (15) is up and the release bar (18) is pushed back by the restoring device blade (23a) in the state that the toilet seat is closed. . When the pedal bar (9) is pressed down, the moving device (15) is pushed down so that the restoring device (23) moves downward so that the first gear (11) fixed to the restoring device (23) rotates downward and simultaneously through the gear device. The connecting rod (7) with the vertical movement bar (27) is raised upwards, so that the toilet seat (6a or 6b) of the toilet seat linkage is moved backward along the hole of the toilet seat linkage guide bar (8), the chair is raised I will go. At this time, since the release bar 18 is retracted backward by the restoring device blade 23a, as shown in (b) of FIG. 5, the release bar blade 20 passes behind the guide bar 26 and is thus first. The locking jaw 11a of the first gear is caught by the right half of the locking device 25 so that the toilet seat chair is fixed in a raised state. In this process, the protrusion 34 on the upper left side of the vertical motion bar shown in FIG. 3 is prevented from being pushed up by the vertical motion bar return spring 33 to prevent the vertical motion bar 27 from rising at an excessive speed. Will not hit hard on the toilet bowl. Subsequently, when the foot is released from the pedal bar 9, as shown in (c) of FIG. 5, the locking jaw 11a of the first gear is caught on the locking device 25 as it is, and is located behind the movable bar 15. The pedal bar 9 is moved upward with the movable bar 15 by the movable bar return spring 17 to return to the original position. In this process, the release bar 18 located inside the movable bar 15 is a restoring device blade ( Since it is out of the influence of 23a), it is converted to the state forward by the action of the own spring 21. When the pedal bar (9) is pressed again after the urination is completed, the moving bar (15) moves downward along with the pedal bar (9), as shown in (d) of FIG. Since the 18) is in the forward state, the release bar blade 20 proceeds along the front of the guide bar 26, so that the left half of the locking device 25 is pushed and released. Since the locking device 25 is in the unlocked state, when the foot is released from the pedal rod 9, the vertical movement bar return spring 33 shown in FIG. 3 pushes down the protrusion 34 on the upper left side of the vertical movement bar. When the toilet seat reaches an angle of less than 90 degrees, the force of gravity acts by the weight of the toilet seat itself, and the projection 6a or 6b of the toilet seat linkage guide bar (for the toilet seat linkage bar) While moving forward along the hole of 8), the vertical movement bar (27) continues to be lowered down so that the toilet seat is completely lowered. At the same time, the first gear 11 is rotated upward through the gear device to return to the original position, and the restoring device 23 attached to the first gear pushes the movable rod 15 upward to return to the original position. . In this process, since the release bar blade 20 is free from the influence of the guide rod 26, the release bar 18 located inside the movable bar 15 is as shown in (a) of FIG. 5. The elastic force of the spring 21 of the unwinding rod is weaker than the elastic force of the spring 24 of the restoring device. In this way, since the release bar 18 is converted to the backward state, the next time the pedal bar 9 is pressed, the release bar blade 20 passes through the guide bar 26 as shown in (b) of FIG. 5. Thus, the locking device 25 can be operated again.
