The present invention relates to a kerep replacement assisting tool that enables kerep replacement work at a water faucet without closing the main tap of the water.
In particular, the present invention relates to a kerep replacement assisting tool that enables kerep replacement work at a water faucet without closing the main tap of the water supply and without scattering water to the surroundings.
Further, the present invention relates to a Kelep replacement assisting tool that enables easy component replacement even when a component is worn or damaged.

As shown in FIG. 14, the pipe of the water supply 10 in each consumer such as a general household or a business establishment is a water meter from the distribution main to the water supply pipe 12 in each consumer via the distribution branch pipe (not shown). After 14 and the main on-off valve (main plug) 16 are installed, they are connected to individual faucets 18 in kitchens, washrooms, etc. As shown in FIG. 15, the faucet 18 is mainly composed of a faucet main body 20, a kerep 22, and a spindle 52. Generally, a kerep (faucet piece) 22 is used for discharging and stopping water at the faucet 18, and the kerep 22 is composed of a disk-shaped packing receiving portion 24 and a valve packing 26. If the valve packing 26 is worn and water leaks, replace the Kelep 22. Next, the outline of the faucet 18 will be described with reference to FIG. The faucet body 20 is usually fixed by screwing one end into a metal or resin water pipe (not shown) embedded in the wall 28. The faucet body 20 is hollow as a whole, and is divided into an inlet passage 34 which is an inlet 30 connected to the water supply pipe 12 and an outlet passage 38 connected to the discharge port 36 by a partition wall 32 formed in the middle of the inside. Has been done. Therefore, the faucet 18 includes a water passage 40 consisting of an inlet passage 34 and an exit passage 38. A circular communication hole 42 connecting the entrance passage 34 and the exit passage 38 is formed in the partition wall 32, and a ring-shaped valve seat 44 is formed on the peripheral edge of the communication hole 42 on the exit passage 38 side. .. In other words, a valve seat 44 is arranged in the middle of the water passage 40. A spindle storage cylinder 48 is formed coaxially with the axis 46 of the communication hole 42 and communicates with the outlet passage 38 at a predetermined angle, and a spindle female screw portion 54 into which the spindle 52 is screwed is formed on the inner surface thereof. In other words, the spindle holding hole 56 is formed in the direction intersecting the outlet passage 38, and the spindle female screw portion 54 is formed in the middle of the spindle holding hole 56. In the spindle 52, a spindle male screw portion 58 is formed in a large diameter portion, and a kerep mounting hole 60 is formed in a lower end portion along an axis 46. When the spindle male screw portion 58 is screwed into the spindle female screw portion 54 and is rotated in the screwing direction, the Kelep 22 approaches the valve seat 44, and when it is rotated in the loosening direction, it is separated from the washer 62. A washer 62 and a triangular packing 64 are mounted in the middle of the spindle 52, and a cap nut female screw portion 68 formed on the inner surface of the lower end portion of the cap nut 66 is formed on the outer peripheral surface of the upper end portion of the spindle storage cylinder 48. It is screwed and held by the screw portion 72. A handle 74 is attached to the end of the small diameter portion 70 at the upper end of the spindle 52 and is fixed by a screw 76. The packing receiving portion 24 of the Kelep 22 has a cylindrical packing portion 78 having a small diameter at the upper end and a disk-shaped packing receiving portion 24 having a diameter larger than that of the valve seat 44 at the middle, and a circular valve packing is formed on the end surface of the packing receiving portion 24. 26 is fixed. As a result, when the spindle male screw portion 58 is rotated in the screwing direction by turning the handle 74, the valve packing 26 is pressed against the valve seat 44 in cooperation with the spindle female screw portion 54, and the faucet 18 is in the closed state. Then, the outflow of water from the discharge port 36 is stopped. On the other hand, when the handle 74 is rotated in the loosening direction of the spindle male screw portion 58, the valve packing 26 separates from the valve seat 44 and tap water flows out vigorously from the discharge port 36.

If the valve packing 26 is worn out and does not adhere to the valve seat 44, resulting in a water leak, the Kelep 22 needs to be replaced. The replacement work of Kelep 22 will be described with reference to FIGS. 16 and 17. First, as shown in FIG. 16 (A), loosen the screw 76 to remove the handle 74 from the upper end of the upper end small diameter portion 70 of the spindle 52, and then loosen the cap nut 66 as shown in FIG. 16 (B). Remove from the storage cylinder male screw part 72 (spindle storage cylinder 48). Next, as shown in FIG. 17, the spindle 52 is turned in the loosening direction to release the screw between the spindle male screw portion 58 and the spindle female screw portion 54, and then the spindle 52 is pulled out from the spindle storage cylinder 48. When the spindle 52 is pulled out, the kerep 22 is integrally pulled out, or the kerep 22 remains in the spindle storage cylinder 48. The remaining Kelep 22 is picked up with tweezers or the like, the cylindrical portion 78 of the new Kelep 22 is inserted into the Kelep mounting hole 60, and then the Kelep 22 is assembled to the faucet body 20 in the reverse procedure of the above. Normally, this replacement work is performed with the main on-off valve 16 closed. This is to prevent scattering of tap water from the spindle holding hole 56 to the surroundings, to prevent flooding of the floor surface, and to facilitate work. However, in factories where many faucets 18 are installed, kitchens in cafeterias, etc., the piping between the main on-off valve 16 and many faucets 18 may be installed in a complicated manner, and the main corresponding to the faucets 18 may be installed. It may be difficult to find the on-off valve 16. In addition, the main on-off valve 16 and the faucet 18 may be far apart, and it is strongly requested that the Kerep 22 be easily replaced without closing the main on-off valve 16 in order to improve work efficiency. Has been done. In addition, when the faucet 18 is installed in the room, it is an essential requirement that the inundation problem associated with the replacement of the kerep 22 does not occur. Further, the handle 74 is usually attached to the upper side, but in rare cases, it may be arranged on the opposite lower side, and the handle 74 is not limited to the position of the handle 74, and the main on-off valve 16 is not closed. It was requested to be able to exchange. The following techniques have been proposed to meet these demands.

As a first prior art, a cloth bag having a substantially vertically long ball shape is formed, an opening protruding in the horizontal direction is provided in the center of one side surface of the cloth bag, and a rope is placed on one side edge of the opening in the vicinity of the opening. A chuck provided in the vertical direction at the center of the other side surface of the cloth bag, a temporary stopper provided at the upper end, and a driver provided near the temporary stopper, which are fixed to the central portion divided into equal lengths in the vertical direction. , A coma packing replacement tool that consists of a net provided at the lower end, seals the existing water faucet inside the cloth bag from the above opening, and replaces the coma packing of the existing water faucet with the new coma packing. Is known (Patent Document 1).

As a second prior art, it is a deep socket-shaped water tool suitable for replacing the faucet top and the upper set of the faucet, and the peripheral wall for the guide protrudes from the outer peripheral edge of the socket portion on the diameter side. The installed water tools are known (Patent Document 2).

As a third conventional technique, when a fastener such as a drain cap attached to the tip of a pipe is loosened or removed, the fastener is fastened while preventing the leaked liquid or gas from being applied to the operator even if an internal pressure is applied. In order to be able to remove the tool and improve work safety, the main body part having an engaging part engaged with the fastener such as a drain cap having a screw part on the tip side of the rod part, and the main body part. A cover member that is mounted and surrounds the periphery of the engaging portion is provided, and an opening through which the fastener can be inserted is formed on the side of the cover member opposite to the main body portion. A wrench with a cover is known (Patent Document 3).

Patent No. 4740311 (paragraphs 0007 to 0014, FIGS. 1 to 8) Utility model registration No. 3197807 (paragraphs 0009 to 0026, Fig. 1-Fig. 3) JP-A-2005-125434 (paragraphs 0006 to 0012, FIGS. 1-Fig. 4)

In the first conventional technique, the water faucet is stored in a cloth bag having a substantially vertically long ball shape, and then the cloth bag is tied to the water faucet with a rope. Next, open the zipper provided in the vertical direction of the cloth bag, insert a hand from there, remove the old kerep (top), attach a new kerep, and return it to the original state. In the first prior art, it is necessary to tie the cloth bag to the water faucet with a rope before the start of the work and to remove the rope after the work, which is extremely complicated. Also, if the kerep is replaced without closing the main on-off valve, the tap water flowing out from the spindle holding hole will not be blocked by the cloth bag and scattered over a wide area, but since the bottom of the cloth bag is a net, It is clear that it will fall to the floor. If the dropped floor is a drainage structure or outdoors, there is no problem, but in other cases, the floor is flooded and if the handle of the faucet is installed upside down, use a rope to attach a cloth bag to the faucet. It has to be tied up and is difficult to adopt.

In the second conventional technique, since the guide peripheral wall is projected from the outer peripheral edge of the socket portion on the diameter side, the guide peripheral wall can be guided to replace the kerep, etc., and the main on-off valve can be used. Even if the valve is not closed and tap water spouts vigorously from the spindle hole, there is an advantage that the work can be done easily, but the tap water flowing out from the socket part (spindle holding hole) has a through hole. As with the first conventional technique, it is difficult to adopt it because it flows out to the surroundings and floods the floor surface.

In the third prior art, a main body portion having an engaging portion engaged with the fastener on the tip end side of the rod portion and a cover member mounted on the main body portion and surrounding the periphery of the engaging portion are provided. Since the cover member is provided with an opening through which the fastener can be inserted on the side opposite to the main body side, when the drain cap is loosened, liquid or the like can be discharged from the pipe at an unexpected timing. Even if it leaks, the blown out liquid or gas hits the inner surface of the cover member and travels inside the cover member, and flows out or goes out from the opening of the cover member, so there is an advantage that adverse effects on the operator can be avoided. However, since the cover member is integrated with the main body that engages with the fastener, there is a problem that it is difficult to adopt it in the kerep replacement work that requires work separately from the fastener.

In the first embodiment, the mounted body body 108 has a predetermined diameter. It is a cylinder with a through hole 114, and a tapered portion 116 is formed at the upper end of the outer surface, a concave groove 118 is formed at the middle of the outer circumference, and the lower inner surface is screwed into the male screw portion 72 of the storage cylinder. A female screw portion 122 to be attached is formed. The tapered portion 116 has a guide function for guiding the mounting body 104 when the mounting body 104 is mounted, and its extension line is formed so as to intersect the axis of the through hole 114 at about 30 degrees. The concave groove 118 has a function of holding the elastic friction body 112 so as not to shift in the axial direction of the attached body main body 108, and is a concave groove having a square cross section formed on the entire circumference of the attached body main body 108. The female screw portion 122 of the mounted body is a female screw portion screwed into the male screw portion 72 of the storage cylinder. In the first embodiment, a packing groove 124 having a square cross-sectional groove is formed on the entire inner circumference of the inner peripheral surface of the through hole 114 on the upper side of the female screw portion 122 of the mounted body, and the packing 126 is fitted therein. When replacing the Kelep 22, the mounted body 108 is the spindle storage cylinder of the faucet body 20 by screwing the mounted female screw portion 122 into the storage cylinder male screw portion 72 after the cap nut 66 is removed. It is fixed to the upper end of the 48, and the frictional resistance between the packing 126 and the upper end surface of the spindle storage cylinder 48 prevents the mounted body body 108 from rotating and is held so that it does not easily fall off. The body to be mounted 108 is preferably molded from a material having a predetermined strength and resistant to rust, for example, brass or resin. The outer shape of the attached body body 108 may be a polygon such as a quadrangle or a pentagon, or an ellipse. This is because it is easy to tighten by hand 162H in the case of a square shape or the like. When the outer shape of the mounted body 108 is square or elliptical, the shape of the receiving hole 142 of the mounted body 104, which will be described later, needs to be shaped accordingly.

Next, the elastic friction body 112 will be described.
The elastic friction body 112 has a function of holding the mounting body 104 to the mounted body 102 by frictional force, a part of the inside thereof is located in the packing groove 124, and a part of the outside thereof is from the outer periphery of the mounted body 102.

In the first embodiment, the elastic friction body 112 uses an O-ring made of synthetic rubber. O-rings are common mechanical parts and can be obtained inexpensively and easily. However, elastic friction bodies 112 other than Olling, such as thermosetting resin-based elastomers such as natural rubber, synthetic rubber, silicone rubber, and fluororubber, and thermoplastic elastomers can be adopted. Further, the elastic friction body 112 may be one that exhibits the above-mentioned holding function of the attached body 102 by projecting at one or more places without uniformly projecting over the entire circumference like the O-ring.

Next, the mounting body 104 will be described mainly with reference to FIG.
The mounting body 104 has a function of holding the water collecting cover 106 mounted on the mounted body 102 on the faucet main body 20, and in the first embodiment, the cylindrical mounting body main body 132 and the holding body 134. Includes.
The mounting body 132 has a function of being fitted to the outer periphery of the mounted body 102 and supported by the mounted body 102 and a function of being attached to the water collecting cover. In the first embodiment, the mounted body 132 is formed into a stepped tubular body. It is configured. Specifically, the middle to the lower end is formed in the large diameter portion 136, the upper end portion is formed in the small diameter portion 138 having a smaller diameter than the large diameter portion 136, and the mounted body 102 is fitted in the large diameter portion 136. Although possible, the elastic friction body 112 protruding outward from the mounted body 102 is formed in a receiving hole 142 having a diameter that cannot be advanced without elastic deformation. On the other hand, the small diameter portion 138 has the same mounting body axis 144 as the receiving hole 142, and a through hole 146 having a smaller diameter than the receiving hole 142 is formed. Therefore, the receiving hole 142 and the through hole 146 communicate with each other, and a step portion 148 is formed between them. The small diameter portion 138 is inserted into a round hole 152 formed in the water collecting cover 106 described later, is sandwiched by a ring-shaped holding body 134 applied from the inside of the water collecting cover 106, and is integrated with the water collecting cover 106. Will be done.
The mounting body 104 covers the mounted body 102 screwed to the upper end of the spindle storage cylinder 48 of the faucet main body 20 from the upper side in FIG. 6, receives the mounted body 102 in the receiving hole 142, and elastically rubs. The body 112 is deformed and inserted until the upper end surface of the mounted body 102 abuts on the step portion 148 (see FIG. 7). The through hole 146 is formed to have a larger diameter than the spindle holding hole 56. Therefore, when the spindle 52 is rotated in the direction of unscrewing the spindle female screw 54 and the spindle male screw 58 in the state where the mounting body 104 is mounted on the mounted body 102, the spindle 52 is passed through the through hole 146. Can be extracted.

Next, the water collecting cover 106 will be described.
The water collecting cover 106 has a function of covering the tap water flowing out from the spindle holding hole 56 so as not to scatter to the surroundings when the kerep 22 is replaced. In the first embodiment, the vertical cross section is formed in a rectangular shape. An insertion opening 154 is provided at the end to allow an operator's hand to be inserted, and the mounting body 104 is attached to the peripheral wall 156 at a predetermined position, and drainage is performed on the peripheral wall between the mounting body 104 and the insertion opening 154. The device 158 is formed. The water collecting cover 106 is preferably transparent and has elasticity. This is because the transparency allows the Kerep 22 to be replaced while checking the inside of the water collecting cover 106 and the positional relationship of the parts. Therefore, it is preferable that the water collecting cover 106 has high transparency. In addition, the faucet 18 can be installed in various situations and may be installed in a narrow space. When the work space is limited, the water collecting cover 106 has flexibility so that it can be attached to the faucet body 20. It is preferable to be able to do so. Therefore, as the material of the water collecting cover 106, polyethylene resin, EVA resin, polystyrene resin, AS resin, PET resin, acrylic resin, viriniden chloride resin, polycarbonate and the like can be adopted, but flexibility and predetermined work can be adopted. PET resin is preferable in consideration of maintaining space. The shape of the water collecting cover 106 is not limited to a rectangular cross section, but may be a circular cross section, a triangular cross section, or a polygon having a pentagon or more cross section. It should be large enough to insert the 162H) and attach / detach the Kelep 22. However, the size of the water collecting cover 106 is not particularly limited, but from the viewpoint of handling, it is preferable to reduce the size and weight as much as possible. In the case of miniaturization, the water collecting cover 106 may be formed of a flexible material and folded so as to be miniaturized. Further, in the first embodiment, the water collecting cover 106 is made as small as possible so that it can be used even in a narrow space. Therefore, the water collecting cover 106 substantially surrounds the through hole 146 so that the tap water flowing out from the spindle holding hole 56 does not scatter to the surroundings. Specifically, as shown in FIG. 1, the top wall 106C facing the through hole 146, the left wall 106L located on the left side, the right wall 106R located on the right side, and the bottom wall 106B to which the mounting body 104 is attached. , It can be said that the insertion opening 154 is substantially enclosed because it is far from the through hole 146. In other words, since the through hole 146 is surrounded on all sides, the tap water flowing out from the spindle holding hole 56 via the through hole 146 is the top wall 106C, the left wall 106L, the right wall 106R, and the bottom wall 106B. , The back wall 106D, and the structure of the insertion opening 154 located at a distant position do not scatter. Top wall 106C. The length of the left wall 106L, the right wall 106R, and the bottom wall 106B is about 150 mm, and a PET bottle having a capacity of 3 to 5 liters can be diverted. It is preferable that the tip portion 106H of the water collecting cover 106 to which the mounting body 104 and the drainage device 158 are attached has the rigidity of a commercially available PET bottle. This rigidity creates a space for moving the worker's hand 162H. Further, the water collecting cover 106 in the vicinity of the insertion opening 154 is preferably composed of a flexible portion 106S made of a flexible impermeable material. This is to increase the degree of freedom in the movement of the arm 162A, further improve the adhesion of the water collecting cover 106 to the worker's arm 162A, and prevent the outflow and leakage of tap water.

Next, the insertion opening 154 will be described.
Since the insertion opening 154 works in the water collecting cover 106, the operator has a function of inserting the hand 162H (left hand 162L or right hand 162R) into the water collecting cover 106, and in the first embodiment, the flexible portion. An opening provided at the end of the 106S, which is a close contact means 164 that is brought into close contact with the arm 162A (forearm or upper arm) to prevent tap water in the water collecting cover 106 from easily leaking from the insertion opening 154. It is preferable to provide it.

Next, the close contact means 164 will be described.
The close contact means 164 has a function of bringing the water collecting cover 106 of the portion constituting the insertion opening 154 into close contact with the worker's arm 162A (forearm or upper arm), and in the first embodiment, the end portion of the flexible portion 106S. It is formed in the shape of a cuff that can be expanded and contracted by the rubber tape sewn on. The close contact means 164 can adopt other means as long as it exerts the above function, for example, it can be tied to the arm with a string, or it may be fastened from the outside with a rubber band instead of the string, and it is not always flexible. It does not have to be integrated with part 106S.

Next, the drainage device 158 will be described mainly with reference to FIG.
The drainage device 158 has a function of discharging the tap water that has flowed out into the water collection cover 106 to the outside of the water collection cover 106. In the first embodiment, the drainage body 168, the drainage body fixing ring 172, and the drainage pipe are used. Since 174 is included and the drainage device 158 is provided at four locations with respect to the peripheral wall 156 of the water collection cover 106, the drainage device 158 parallel to the mounting body 104 is set as the first drainage device 158A in a clockwise direction. The second drainage device 158B, the third drainage device 158C, and the fourth drainage device 158D will be described, but these have the same configuration and will be described below on behalf of the first drainage device 158A. By installing the drainage devices 158 at four locations, in the first embodiment, the cross section of the water collecting cover 106 is rectangular, so that the installed state of the faucet body 20 is the normal state (the discharge port 36 faces downward). One of the four drainage devices 158 was arranged upward and flowed out from the drainage port 178 of the drainage device 158 into the water collecting cover 106 even in the inverted state, the left facing state, or the right facing state. This is because tap water can be drained. Therefore, when the mounting state of the faucet body 20 is dedicated to one type such as the normal state, only one drainage device 158 may be provided side by side on the same peripheral wall 156 as the mounting body 104.

First, the drainage body 168 will be described.
The drainage body 168 has a function of forming a drainage port 178 on the peripheral wall 156 of the water collecting cover 106, and in the first embodiment, the drainage body 168 is composed of a circular flange 182 at the upper end portion and a cylindrical body 184 extending downward at a predetermined length. , The upper end of the circular flange 182 constitutes the drainage port 178. The drainage body 168 is formed of a non-rust metal, a resin, or the like, but is molded of the resin in the first embodiment from the viewpoint of weight reduction. The cylindrical body 184 is attached to the water collecting cover 106 by adhesion or welding with the ring-shaped drainage body fixing ring 172 inserted into the drainage port hole 186 formed in the peripheral wall 156 of the water collecting cover 106 fitted to the outer periphery. It is fixed.

Next, the drainage pipe 174 will be described.
The drainage pipe 174 has a function of guiding tap water flowing out from the drainage port 178 to a predetermined drainage position, and in the first embodiment, the cylindrical body 184 is made of flexible vinyl having a predetermined length. The drainage pipe 192 to have is used. Since the drainage pipe 192 is flexible and has a predetermined length, the open tip can be arranged in an enlarged portion or the like installed on the floor surface. In the first embodiment, the tap water flowing out from the spindle holding hole 56 is held in the water collecting cover 106, and when a predetermined amount or more stays, the water level in the water collecting cover 106 rises and reaches the drain port 178. , It flows into the drainage port 178 and is guided to a predetermined drainage section via the drainage pipe 174 to be drained. Therefore, by using the drainage device 158, there is an advantage that the tap water flowing out from the spindle holding hole 56 can be drained without flooding the floor surface or the like. When the Kelep replacement assisting tool 100 is used outdoors, if the floor surface or the ground may get wet, the drainage device 158 may not be provided and the drainage body 168 may be simply provided. Further, when a plurality of drainage devices 158 are provided, the drainage pipe 174 is connected to the drainage body 168 located at the lowermost part, and for the other drainage devices 158, a blind plug is fitted at the outlet of the cylindrical body 184. You may do so.

Next, the work of replacing the kerep 22 by using the kerep replacement assisting tool 100 of the first embodiment according to the present invention will be described with reference to FIGS. 6 and 7. In this description, it is assumed that the faucet 18 is installed in a normal installation state, and the discharge port 36 is installed in a downward state.

First, as described in the prior art, the screw 76 is removed and the handle 74 is removed from the tip of the upper end small diameter portion 70 of the spindle 52.

Next, loosen the cap nut 66 using a tool such as a spanner to release the screw between the male screw portion 72 of the storage cylinder and the female screw portion 68 of the cap nut, and remove the cap nut 66 from the spindle storage cylinder 48.

Next, the triangular packing 64 and the washer 62 are removed. In this state, in the spindle 52, since the spindle male screw portion 58 is screwed into the spindle female screw portion 54 and the valve packing 26 is in close contact with the valve seat 44, tap water does not flow out from the spindle holding hole 56. do not have.

Next, the mounted body 102 is mounted on the spindle storage cylinder 48. Specifically, in a state where the female screw portion 122 of the mounted body is applied to the end of the male screw portion 72 of the storage cylinder, the hand 162H is used to rotate the female screw portion 122 in the screwing direction to screw the male screw portion 72 of the storage cylinder into the packing. When 126 is compressed to the end face of the spindle storage cylinder 48 and the screwing force of the mounted body 102 exceeds a predetermined value, the screwing is completed (see FIG. 6). A tool may be used for screwing the attached body 102.

Next, the water collecting cover 106 is held by the hand 162H, and the mounting body 104 is mounted on the mounted body 102. That is, the receiving hole 142 of the mounting body 104 is applied to the mounted body 102 so as to fit into the mounted body 102, and is pushed down from above. As a result, the elastic friction body 112 is pressed and deformed by the inner peripheral surface of the receiving hole 142, so that the elastic friction body 112 is received in the receiving hole 142, and the inner surface of the receiving hole 142 and the outer peripheral surface of the elastic friction body 112 The mounted body 104 is pushed down until the stepped portion 148 is brought into contact with the upper surface of the mounted body 102 by overcoming the frictional force of the mounted body 104. As a result, the outer peripheral surface of the elastic friction body 112 comes into contact with the inner peripheral surface of the receiving hole 142 with a predetermined contact pressure. Therefore, even if an external force acts on the mounting body 104, the frictional force due to the contact pressure causes the mounting body. The 104 will not fall off the attached body 102. In other words, the catchment cover 106 is attached so that it does not easily fall off from the attached body 102, and therefore the faucet body 20.

Next, the replacement Kelep 22 is inserted into the water collecting cover 106 through the insertion opening 154. The replacement kerep 22 may be arranged in the water collecting cover 106 in advance.

Next, the operator inserts the dominant hand 162H from the insertion opening 154 through the insertion opening 154. By this insertion, the close contact means 164 constituting the insertion opening 154 of the water collecting cover 106 expands and contracts due to its elasticity, and automatically comes into close contact with the worker's arm 162A.

Next, the spindle 52 is rotated counterclockwise by hand 162H or by using a tool, and the spindle 52 is taken out from the spindle holding hole 56. At this time, as the screw length between the spindle male screw portion 58 and the spindle female screw portion 54 decreases, tap water begins to leak from the spindle holding hole 56, and after the Kelep 22 is taken out from the spindle holding hole 56, the tap water begins to leak. The amount of runoff is maximum. As a result, even when tap water is vigorously ejected from the spindle holding hole 56, the spindle holding hole 56 is surrounded on five sides by the peripheral wall 156, and the insertion opening 154 is blocked by the arm 162A or the spindle. Since it is far from the holding hole 56, the ejected water does not scatter to the surroundings. When the spindle 52 is taken out from the spindle holding hole 56, the kerep 22 may be taken out as a unit without falling out of the kerep mounting hole 60. If Kelep 22 remains in the spindle holding hole 56, pick up the cylindrical portion 78 with tweezers or the like and take it out.

Next, the replacement kerep 22 is inserted into the spindle holding hole 56, then the spindle 52 is inserted into the spindle holding hole 56, the spindle male screw portion 58 is screwed into the spindle female screw portion 54, and the valve packing 26 is screwed. It is brought into close contact with the valve seat 44 to stop the outflow of tap water. To replace the Kelep 22, take out the spindle 52 from the water collection cover 106, insert the columnar portion 78 of the Kelep 22 into the Kelep mounting hole 60 in the spindle 52, integrate it, and then insert the water collection cover again from the insertion opening 154. After inserting it into the 106, as described above, the Kelep 22 and the spindle 52 may be inserted into the spindle holding hole 56 and then screwed to be mounted. During this replacement, tap water flows out of the spindle holding hole 56 into the catchment cover 106. The spilled tap water is prevented from scattering to the surroundings by the peripheral wall 156 and collects in the lower part. In the first embodiment, the mounting body 104 and the drainage body 168 are collected on the bottom wall 106B to which the mounting body 104 and the drainage body 168 are attached, and drained from the drainage port 178 to an appropriate drainage place via the drainage pipe 174, so that even if it is indoors. , The floor surface, etc. will not be flooded.

Next, the water collecting cover 106 is pulled up to remove the mounting body 104 from the mounted body 102.

Next, the mounted body 102 is loosened to cancel the screwing between the male screw portion 72 of the storage cylinder and the female screw portion 122 of the mounted body, and the mounted body 102 is removed from the spindle storage cylinder 48.

Next, a washer 62 and a triangular packing 64 are installed at the upper end of the spindle storage cylinder 48, and the cap nut female screw portion 68 of the cap nut 66 is screwed into the storage cylinder male screw portion 72.

Next, the handle 74 is fitted to the tip of the spindle 52, and the screw 76 is screwed in to fix it so that it will not fall off. This completes the replacement work for Kelep 22.

When the discharge port 36 of the faucet 18 is mounted upward, the tap water flowing out from the spindle holding hole 56 collects on the top wall 106C and is provided on the top wall 106C, contrary to the above description. The water is drained from the drain port 178 of the third drain device 158C. When the discharge port 36 of the faucet 18 is oriented sideways to the left or right, the tap water flowing out from the spindle holding hole 56 collects on the left wall 106L or the right wall 106R, and the second drainage device 158B or the second drainage device 158B or the second is arranged therein. 4 It is drained from the drainage device 158D. Therefore, when the use of the Kelep replacement assisting tool 100 is to be used only in the normal case where the discharge port 36 of the faucet 18 faces downward, the drainage device 158 should be provided with only the first drainage device 158A attached to the mounting body 104. good. When the discharge port 36 faces downward and upward, the first drainage device 158A and the third drainage device 158C may be provided. In the first embodiment, the faucet 18 normally installed has been described as an example, but the faucet having the same configuration, for example, water used for a washing machine, a washroom, a kitchen, a bathroom, and the like. It can be used to replace the kerep in the faucet.

Next, Example 2 according to the present invention will be described with reference to FIG.
The second embodiment is an example in which the vertical cross-sectional shape of the water collecting cover 106 is circular. A circle is a concept that includes an ellipse as well as a perfect circle. In the second embodiment, for convenience, the mounting body 104 is attached to the lowermost part of the catchment cover 106 having a circular cross section, and the first drainage device 158A is provided in parallel with the mounting body 104, and the second drainage device is provided. The 158B and the third drainage device 158C are installed at intervals of 120 degrees, and a total of three are arranged.
When the water collecting cover 106 of the second embodiment is used, the mounting method to the faucet main body 20 and the replacement work of the kerep 22 are the same as those of the first embodiment. When the discharge port 36 of the faucet 18 faces upward, the outflowing tap water collects on the peripheral wall 156 on the opposite side, and after the water level reaches the drain port 178 of the second drainage device 158B or the third drainage device 158C, the drainage is concerned. It is discharged from the mouth 178. When the water collecting cover 106 having a circular cross-sectional shape is used as in the second embodiment, the number of drainage devices 158 can be reduced, so that there is an advantage that the water collecting cover 106 can be constructed at low cost.

Next, Example 3 will be described with reference to FIG.
The third embodiment is another example of the close contact means 164, and the same parts as those of the first embodiment are designated by the same reference numerals to explain different configurations. The adhesion means 164 in the third embodiment is an example of utilizing a hook-and-loop fastener, so-called magic tape (registered trademark) 194. That is, the velcro 194 is attached to the end of the flexible portion 106S, the hand 162H is inserted into the water collecting cover 106 from the insertion opening 154, and then the velcro 194 is attached in close contact with the circumference of the arm 162A. To combine. As a result, even if the tap water collected in the water collecting cover 106 flows toward the insertion opening 154, the end of the flexible portion 106S is in close contact with the peripheral surface of the arm 162A by the magic tape 194. , It does not leak from the inside of the water collecting cover 106. As the contacting means 164, in addition to Examples 1 and 3, an annular elastic body can be pressed and attached from the outside of the flexible portion 106S, and as a result, the flexible portion 106S can be brought into close contact with the periphery of the arm 162A. Further, the magic tape 194 may be separated from the flexible portion 106S and wound from the outside of the flexible portion 106S. Further, the flexible portion 106S can be attached by tying the flexible portion 106S from the outside of the flexible portion 106S with a string.

Next, Example 4 will be described with reference to FIG.
In the fourth embodiment, the shape of the water collecting cover 106 to which the drainage device 158 is attached and the number of the drainage devices 158 are different from those in the first embodiment. Specifically, the wall surfaces of the water collecting covers 106 on both sides of the mounting body 104 in the water collecting cover 106 are formed so as to be located downward. In the fourth embodiment, since the water collecting cover 106 is formed in a cylindrical shape, the enlarged portion 196 in which the wall surfaces on both sides close to the mounting body 104 are expanded in diameter by a predetermined width, specifically, the first enlarged portion It is formed in 196A and the second expansion part 196B. In other words, the enlarged portion 196 is formed in a groove shape.
