[Industrial applications]

 The present invention relates to improvement of a water stopcock of a drainage port, and more specifically, when the waterstop stopper is unplugged from the drainage port of various water tanks, a retaining strip of the waterstop stopper is surely placed in a winding tool. The present invention relates to a water stop cock for a drainage port, which has a feature that it can be rolled up and can be adjusted in a desired amount as needed.

[0002]

[Prior art]

 Normally, the stopcocks of the drainage ports of various water tanks are attached to the wall near the faucet of the water supply or to the tip of the holding strip such as a ball chain whose base end is fixed to the eye plate of the overflow part. .

Further, as disclosed in Japanese Utility Model Publication No. 55-27512, a holding member such as a ball chain of a water stopcock that blocks and closes a drain port of a sink such as a wash basin and a kitchen sink. When the elastic stretchable material is connected and the water shutoff plug is unplugged from the drain port, the shrinkage force of the elastic stretchable material elastically pulls the water shutoff plug toward the upper part of the water tank. There is also known a stopcock for the drain of a sink device.

[0004]

[Problems to be solved by the device]

 However, in the case of the former of the above-mentioned conventional examples, the stopcock removed from the drainage port is placed in the place of an extremely limited narrow space provided at the back of the sink device, or at the tap of the water supply. Although it is hooked, it is difficult to place the stopcock securely in the place because the place is small, and it is easy to drop on the water tank surface of the sink even after placing it, and Depending on the type of sink equipment, there is no space for placing such a water stopcock at all, which is not only inconvenient, but also unfavorable for hygiene. When hooked on a faucet, not only the hooking and removing operations are complicated, but also the hooking state is unsightly, which deteriorates the aesthetics of the kitchen and the like.

Further, in the latter case of the above-mentioned conventional example, the water stopcock removed from the drainage port is automatically elastically pulled upward of the water storage tank by the contracting force of the elastic stretchable material, and the water stopcock is opened. Although it is possible to reliably prevent it from falling into the water tank and remove the former drawback, the removed water stopper has a structure that makes the storage case of the elastic expansion / contraction material have a strong contraction force. When the contraction force is weak, it is suspended in a fixed position between the drainage port and the storage case. There is a problem that it is not convenient because the adjustment cannot be arranged at a desired position.

The present invention has been researched and developed with the object of solving the above-mentioned problems, and when removing the water stopcock from the drain port, the holding strip of the water stopcock is rolled up by one-touch operation. A drainage stopcock that has the feature that it can be reliably rolled into the tool to facilitate opening, and that the amount of winding and withdrawing can be adjusted as desired, if necessary. The purpose is to provide.

[0007]

[Means for Solving the Problems]

 As a means for solving the above-mentioned problems and achieving the object, in the present invention, a water stopper holding strip mounted on a water stopper for plugging and closing the drain outlet of various water tanks such as a wash tank, a bathtub, and a sink tank. A drain end stop of a bullet pulling and winding tool equipped with a bullet pulling and winding mechanism and a pulling amount / rolling amount adjusting control mechanism. Developed and adopted a faucet.

Further, in the water stopcock of the drainage port configured as described above, it is possible to prevent the floating pipes from clogging the drainage pipes by overflowing floating substances such as floating garbage and floating hair from the overflow ports of various water tanks. To this end, we have developed and adopted a water stopcock for the drainage port, which is characterized in that the bullet catching tool has a plate that is placed at the overflow port of the water tank.

[0009]

[Action]

 In the above configuration, in order to drain the water in the water tank, pull out the water stopper holding strip upward and pull out the water stopper from the drain port, and then pull out the holding strip provided in the ammunition winding tool. When the elastic pulling and winding mechanism of the holding strip provided in the elastic pulling and winding device is operated by operating the adjustment control mechanism of the amount of winding and the winding amount, the elastic holding and pulling action of the winding mechanism causes the holding strip to be held. Is caught in the elastic pull-up retractor and raises the water stopper to the attachment position of the retractor.

At this time, when it is necessary to stop the water stopcock during pulling up, the operation of the adjustment control mechanism may be stopped, and when the drainage port is closed with the water stopcock. For the above, it is only necessary to perform the operation of pulling out the holding strip from the winding tool. That is, only when the adjustment control mechanism is operated, the holding strip is rolled up to raise the water stopcock, and when the adjustment control mechanism is not operated, the holding strip maintains the position at that time, and If you want to pull out the strip from the winding tool, you can pull it out smoothly by pulling out the holding strip.

【Example】

 An example of an embodiment of the present invention will be described below with reference to the accompanying drawings. In this embodiment, a drainage stopcock of the present invention is a drainage stopcock 1 of a bathtub B. It is composed of a water stopper holding strip 2 such as a ball chain having a tip attached to the water tap 1, and an elastic pulling and winding tool 3 of the holding strip to which the base end of the holding strip 2 is attached. The elastic draw-in tool 3 includes the casing 4, the elastic draw-in mechanism 5 of the holding strip 2 rotatably housed in the casing 4, and the holding housed in the casing 4 as well. It is composed of an adjusting control mechanism 6 for adjusting the amount of pulling out and the amount of winding of the strip 2.

In this embodiment, the casing 4 is made of a plastic shallow cylindrical body, and is provided with the through hole 7 of the holding strip 2 on the circumferential side surface thereof and the upper wall 8 a thereof. It is configured to be openable and closable with screws (not shown), etc. to facilitate maintenance and inspection.

Further, in this embodiment, the elastic pull-in mechanism 5 of the holding strip 2 has the upper end exposed to the outside at the center of the casing 4 and the lower end slightly separated from the bottom wall 8 b of the casing 4. A cylindrical body 9 inserted and fixed in the up-down direction in this state, a rotating case 10 for rotatably surrounding the cylindrical body 9 for accommodating a leaf spring having an open top, and the inside of the rotating case 10. The leaf spring 11 is housed in the rotating case 10 in a wound state, and the inner end portion 11a of the leaf spring 11 is attached to the cylindrical body 9. In addition to being engaged, the outer end portion 11b is engaged with the peripheral wall of the rotating case 10.

Further, in this embodiment, the adjustment control mechanism 6 for the withdrawal amount / roll-in amount of the holding strip 2 has the upper and lower portions closed and the left and right ends of the thin cylindrical body 12 with the lower portion opened. If the engaging projections 13 and 13 are provided so as to project toward both sides, and the tapered surfaces 13a and 13a in the same direction are formed symmetrically on the upper surfaces of the outer end portions of the engaging projections 13 and 13 in the same direction. Both of them are fitted in the inverted T-shaped engagement / disengagement operating member 14 and the tubular body 12 of the engagement / disengagement operating member 14 in which substantially vertical abutting surfaces 13b, 13b are provided on the back side of the tapered surfaces 13a, 13a. Then, the returning spring 15 of the engagement / disengagement operation member 14 whose lower part is projected, the engaging recess 16 provided at the lower end of the tubular body 9 in the elastic winding mechanism 5, and the same as shown in FIG. Concentric with the outer bottom surface of the rotating case 10 of the elastic winding mechanism 5. And a taper surface 17a slidably contacting the taper surface 13a of the engaging projection piece 13 and an abutting surface 17b with the abutting surface 13b of the engaging projection piece 13 on the back side thereof. It is composed of a plurality of rotation control protrusions 17 of the rotating case 10, and the cylindrical body 12 is inserted into the cylindrical body 9 from the lower side, and the elastic force toward the upper side of the returning spring 15 causes The head of the tubular body 12 is projected from the upper wall 8a, and the engaging projections 13, 13 of the tubular body 12 are engaged with the engaging recesses 16 provided at the lower end of the tubular body 9. .

Further, on the outer peripheral side surface of the rotating case 10 arranged in the casing 9 in the above-described manner, the base end of the holding strip 2 of the water blocking plug 1 having the tip attached to the water blocking plug 1 is appropriately arranged. The water stopper 1 approaches the through hole 7 of the casing 4 by the elastic force of the wound leaf spring 11 which is attached and wound in the casing 4 with the inner and outer ends 11a and 12b being engaged with each other. It is configured to be wound up in a sufficiently elastically drawn state, and therefore, the elastic force of the wound leaf spring 11 increases as the holding strip 2 is pulled out of the casing 4.

Next, the usage state of the water stopcock of the drainage port configured as described above will be explained together with its operation. This waterstop stopper is, for example, as schematically shown in FIG. The bottom of the plug 3 is fixedly used on the upper surface of the edge of the water tank such as the bathtub B, and when the drain port is plugged and closed by the water stopcock 1, the holding strip 2 is simply wound. It suffices that the leaf spring 11 is pulled out by a required length against the elastic pull-in force and is plugged. That is, when the holding strip 2 is pulled out, in the rotating case 10, the taper surface 17a of the rotation control protrusion 17 provided on the bottom surface of the rotation case 10 slides on the taper surface 13 of the engaging projection piece 13 of the adjustment control mechanism 6. Therefore, the rotating case 10 rotates smoothly, and the holding strip 2 is easily pulled out (see (a) and (b) in FIG. 4).

When it is necessary to interrupt the drawing operation at that position for some reason during the drawing, the drawing operation may be simply stopped or the holding strip 2 may be released. Even if the rotating case 10 tends to reversely rotate due to the restoring elastic force of the leaf spring 11, the engaging projection 13 of the tubular body 12 is engaged with the engaging recess 16 of the fixed tubular body 9. From the relationship, since the abutting surface 17b of the rotation control protrusion 17 abuts on the abutting surface 13b of the engaging projection 13, the rotating case 10 does not rotate in the reverse direction, and the holding strip 2 at that position. Stop (see (c) of FIG. 4).

Next, when the water stopcock 1 is to be unplugged, if the restoring elastic pulling force of the wound leaf spring 11 is relatively weak, it is manually unplugged, and if the restoring elastic pulling force is strong, it is as it is. In this state, the upward protruding portion of the tubular body 12 of the engagement / disengagement operation member 14 may be pushed down against the returning spring 15. That is, when the tubular body 12 is pushed down, the engaging projection 13 provided at the lower end of the tubular body 12 is pushed down to the position shown by the chain line as shown in FIG. Since the engagement with 16 is released, the rotating case 10 is freely rotated in the reverse direction, and the holding strip 2 is wound into the winding tool 3 while the pushing operation is being performed, so that the water stopper 1 can be securely held. It can be pulled up (see (d) in FIG. 4). At this time, when the hand is released from the tubular body 12, the restoring force of the returning spring 15 causes the tubular body 12 to return to its original position, and the engaging projection 13 is moved to the engaging concave portion of the tubular body 9. It engages with the place 16 and the rolling operation of the holding strip 2 is stopped.

According to the above-mentioned embodiment, there is an advantage that the water stopcock 1 having the drainage port plugged and closed can be smoothly and easily removed by one-touch operation, and the amount of the holding strip 2 to be rolled up, if necessary, The amount of withdrawal can be adjusted as desired, and the winding tool 3 can be freely fixed not only on the upper surface of the edge of the bathtub or other water tank but also on the nearby wall surface, etc., so that the upper surface of the edge of the water tank can be easily cleaned. In addition, there is an advantage that it can be installed without any trouble even if the space on the upper surface of the edge is narrow.

Next, FIG. 5 shows another embodiment of the present invention, which is the same as the embodiment described above in that the eyelets 19 are integrally provided on the bottom surface side of the elastic pulling and winding tool 3 with a required space. Only the examples differ, and the other structures do not differ. Therefore, the same parts are designated by the same reference numerals. As shown in FIGS. 5 and 7, the water stopcock of the drainage port shown in this embodiment uses 19 as a perforated plate which is attached to the overflow port 20 of the water tank. For example, in addition to the advantages of the above-described embodiment, there is an advantage that it is possible to prevent the floating pipes, floating hair and other floating substances from overflowing with water from the overflow ports of various water tanks and clogging the drain pipe.

Although the main embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and the object of the invention can be achieved including the change of the material of each member, and It goes without saying that various design changes can be made without departing from the spirit of the invention.
