Note that the petal 32 is not detached from the cover 31 when the locking portions 32 a and 32 b are in contact with the upper surface or the lower surface of the cover 31 during the vertical movement.

  Next, the structure of the pump auxiliary device 5 will be described. First, the pump auxiliary device 5 has a base 11 having a substantially square shape and a hole 11b formed in the center. The hole 11b of the base 11 has a diameter that allows the petal 32 of the water supply pump 3 to pass through without contact. In addition, screw holes 11 a are formed in the four corners of the base 11. Further, a portal-like column 12 is provided on the back side of the base 11 when viewed from the front. The support column 12 is provided with a rotating shaft 16 penetrating left and right, and a link member 15 formed of a round bar 15 a is horizontally provided in a state supported by the support column 12 so as to be swingable by the rotating shaft 16. Specifically, a support 15b that is U-shaped and narrower than the column 12 is provided at one end of the round bar 15a, and the side plate 12a of the column 12 and the side plate 15ba of the support 15b are in contact with each other. The rotating shaft 16 penetrates through the part. The height of the rotary shaft 16 is set higher than the height at which the petal 32 of the water supply pump 3 protrudes above the cover 31.

  A U-shaped pressing member 17 is pivotally supported by a support shaft 18 at a substantially central portion of the round bar 15 a of the link member 15 and substantially above the center of the hole 11 b of the base 11. The bottom surface 17 a of the pressing member 17 is flat and has a shape that can contact the upper surface 32 c of the petal 32 of the water supply pump 3. Further, a rectangular tube-like connecting portion 15c is provided that extends horizontally from the end face of the other end of the round bar 15a in the right direction when viewed from the front. A round bar-shaped operation lever 10 extends upward from the upward surface of the right end of the connecting portion 15c. The upper end of the operation lever 10 is bent in the front-view front direction, and a resin grip 10a is fitted on the tip. A portion from the upper surface of the support column 12 to the front of the base 11 is covered with a plate-like cover 13. Each part of the pump auxiliary device 3 is made of a metal such as stainless steel unless otherwise specified, but may be a resin as long as strength is ensured.

  Next, a method for installing the pump auxiliary device 5 in the feed water pump 3 will be described. First, the pump auxiliary device 5 is placed on the cover 31 of the water supply pump 3 so that the petal 32 of the water supply pump 3 fits in the hole 11 b of the base 11 of the pump auxiliary device 5. At this time, the bottom surface 17a of the pressing member 17 of the pump auxiliary device 5 and the upper surface 32c of the petal 31 come to face each other. Next, the pump auxiliary device 5 itself is supplied with water so that the round bar 15a of the link member 15 of the pump auxiliary device 5 and the toilet bowl 2 are parallel and the upper end of the operation lever 10 faces the front side of the temporary toilet 1 as viewed from the front. Rotate on the cover 31 of the pump 3. At this position, since the position of the screw that stops the cover 31 of the water supply pump 3 and the position of the screw hole 11a of the base 11 coincide with each other, the screw is screwed from the top of the base 11 toward the cover 31, and the pump The auxiliary device 5 is fixed to the water supply pump 3.

  Next, the usage method and operation of the pump auxiliary device 5 will be described. First, the operator sits on the toilet bowl 2 and uses the toilet. At this time, the stool rides on the flapper 2 a provided on the inner bottom of the toilet 2, and at the same time, the flapper 2 a is pushed downward by its own weight and falls into a toilet bowl provided below the toilet 2. The operator pushes down the operation lever 10 of the pump auxiliary device 5 forward as viewed from the operator while the stool is finished, while sitting on the toilet 2.

  Before the operator swings the operating lever 10, in the state shown in FIG. 5, the operating lever 10 is pushed up via the pressing member 17 of the pump auxiliary device 5 by the biasing force of the petal 32 of the water supply pump 3. It has become. At this time, the water supply pump 3 is in a state where water is stored in the bellows 35.

  When the operator pushes down the operation lever 10, as shown in FIG. 6, the link member 15 swings downward with the rotating shaft 16 as a fulcrum via the connecting portion 15c. When the link member 15 swings downward, the holding member 17 caught by the link member 15 is pushed down. The upper surface 32 c of the petal 32 of the water supply pump 3 abuts on the bottom surface 17 a of the pressing member 17, and the petal 32 is also pushed into the pump case 7. The locking portion 32 b of the pressed petal 32 compresses the bellows 35 against the urging force of the spring 36. When the bellows 35 is contracted, the water in the bellows 35 is discharged from the discharge port 34 by pushing the discharge valve 39 open. The discharged water is sent to the toilet 2 through a hose (not shown), and the toilet 2 is washed.

  Next, when the operator releases the hand from the operation lever 10 or removes the hand force, the urging force of the petal 32 wins over the force that pushes down the pressing member 17, and the spring 36 extends and the petal as shown in FIG. 32 is pushed up. At the same time, the bellows 35 is stretched to reduce the pressure in the bellows 35, and the water supply valve 33 is opened to supply water into the bellows 35. The water supply port 33 is connected to a tank in which water is stored by a hose (not shown).

  As described above, the link member 15 of the pump auxiliary device 5 has a structure in which the holding member 17 that is supported by the round bar 15a is in contact with the upper surface of the petal 32 while being swingably disposed horizontally. The shaft 16 constitutes a lever having the fulcrum, the pressing member 17 as the action point, and the operating lever 10 as the power point. For this reason, regardless of whether the operator sits down on the toilet bowl 2, the petal 32 can be pushed in even if the operating lever 10 is operated with a light force according to the principle of leverage, and sufficient water is supplied to the toilet bowl 2. It is possible to send water.

  Further, since the operation lever 10 extends to a height at which it can be operated in the stool state, water can be supplied to the toilet 2 while sitting on the toilet 2. For this reason, since it is possible to remain seated even while the toilet bowl 2 is being washed, it is possible to reduce the burden on the body of an elderly person or a handicapped person.

  Furthermore, since the pressing member 17 is pushed up by the urging force of the pressed petal 32 and the link member 15 is swung upward via the pressing member 17, it is possible to supply water without operating the pump auxiliary device 5 after water supply. It is easy to handle.

  Furthermore, since the pump auxiliary device 5 is placed on the cover 31 of the feed water pump 3 and can be used only by screwing it through the screw hole 11a of the base 11, the mounting is easy. It can be retrofitted to existing temporary toilets.

  FIG. 7 is a right side view showing a pump auxiliary device according to the second embodiment of the present invention. FIG. 8 is a plan view showing the pump auxiliary device.

  The pump auxiliary device 6 according to the present embodiment includes a base member 21 provided with a support column 22 and a round bar 25a. The link member 25 includes a round bar 25a supported on the support column 22 so as to be swingable via a support portion 25b. It is the same as that of the pump auxiliary | assistance apparatus 5 of Example 1 by the point provided with these. Only the differences in structure will be described. In the pump auxiliary device 5, the operation lever 10 is provided in the connecting portion 15 c of the link member 15, but in the pump auxiliary device 6, the operation lever 10 is not provided. And although the shape of the connection part 15 is the same, in the pump auxiliary device 6, it is the step part 25c which can mount a sole.

  Next, a method for installing the pump auxiliary device 6 in the feed water pump 3 will be described. First, the pump auxiliary device 6 is placed on the cover 31 of the water supply pump 3 so that the petal 32 of the water supply pump 3 fits in the hole 21 b of the base 21 of the pump auxiliary device 6. At this time, the bottom surface 27a of the pressing member 27 of the pump auxiliary device 6 and the top surface 32c of the petal 31 are made to face each other. In this state, the position of the screw for stopping the cover 31 of the water supply pump 3 and the position of the screw hole 21a of the base 21 are matched, and the screw is screwed from the top of the base 21 toward the cover 31 to assist the pump. The device 6 is fixed to the feed water pump 3.

  Next, the usage method and operation of the pump auxiliary device 6 will be described. First, the operator sits on the toilet bowl 2 and uses the toilet. At this time, the stool rides on the flapper 2 a provided on the inner bottom of the toilet 2, and at the same time, the flapper 2 a is pushed downward by its own weight and falls into a toilet bowl provided below the toilet 2. After the stool is completed, the operator stands up and steps on the foot part 25c of the pump auxiliary device 6 with his / her foot. When the operator steps on the foot portion 25c, the pressing member 27 pushes the petal 32 down and feeds water to the toilet 2 as in the pump auxiliary device 5 of the first embodiment.

  Next, when the operator removes his / her foot from the foot portion 25c or removes his / her foot force, the urging force of the petal 32 wins over the force of pushing down the pressing member 27, and the spring 36 extends to push up the petal 32. At the same time, the bellows 35 is stretched to reduce the pressure in the bellows 35, and the water supply valve 33 is opened to supply water into the bellows 35.

  As described above, in the pump auxiliary device 6, similarly to the pump auxiliary device 5, since the link member 25 constitutes a lever, the petal 32 is obtained even if the foot portion 25 c is stepped on with a light force on the principle of lever. Can be pushed in, and sufficient water can be sent to the toilet 2.

  Moreover, since the foot part 25c which can mount a sole is provided in the other end of the link member 25, more force of a leg can be transmitted to a link member and water supply can be performed reliably. The foot portion 25c may have a plate shape so that the sole can be securely placed, but by using a prism as in the present embodiment, the sole can be placed securely while being simple. Since the structure is simple, the cost of the pump auxiliary device 6 can be suppressed. Moreover, since it is a prism, there also exists an advantage that a leg | foot is hard to slip.
