Description

  The present invention relates to a drain plug operation mechanism capable of grasping the open / closed state of a drain plug without directly checking the state of the drain plug in a drain plug that is opened and closed remotely.

  The drain plug mechanism that opens and closes the drain plug by remote control using the inner cable is becoming more popular as a so-called cable type because the layout is more flexible than the so-called “link mechanism type”. Therefore, in the case of the cable type, the remote operation cable having the outer casing is extended from the operation portion to the drain plug mechanism, and the operation force is transmitted to the drain plug by the inner cable to be driven to open and close.

  As an operation mechanism of such a drain plug, for example, a plunger in which the drain plug is opened and closed by operating the operating section by operating the operating section, in which the operating section is fastened to the outer tube. It consists of a plunger attached to the core coil that slides with the guide and pulled out from the outer tube, and a plunger outer cylinder that retracts the plunger and attaches to and supports the support (attachment). There is a remote-operated drain plug device characterized by being buffered to a release wire (Patent Document 1). In this remote-operated drain plug device, the core coil slides in the outer tube of the release wire by the operation of the operation unit, protrudes from the plunger guide fastened to the outer tube, and the loose plunger is attached to the end of the core coil. The drain plug connected to the plunger is opened. In other words, since the core coil slides in the outer tube by pushing the operation part and the plunger protrudes, the drain plug is in the projecting state when the drain plug is open. Is in a pushed-in state, and when it is in a closed state, the operation part is in a protruding state on the contrary. Therefore, it is necessary to visually confirm whether the drain plug is in the open state or the closed state.

  However, in the bathroom, if the visibility is poor due to steam, the glasses are cloudy, or the glasses are removed, it may not be possible to confirm whether the drain plug is closed. If the hot water is stored in the bathtub, the hot water is wasted. In addition, there is a case where the bathtub is provided with a lid and hot water is supplied to the bathtub with the lid closed. In that case, if it is mistaken that the bathtub drain plug is closed, all of the hot water supplied will be discharged. , Hot water is wasted.

  In the case of the cable type, the inner cable is led out from the outer casing when the drain plug is pushed up so that the drain plug is opened to transmit the operating force to the drain plug due to the rigidity of the inner cable. For this reason, there is an exposed portion of the inner cable between the drain plug and the outer casing that is not protected, so that when the drain plug hits your hand or shampoo bottle, When an external force is applied, the inner cable may be pulled in and buckled, and may be bent or bitten by a drain plug or the like. In such a case, the guide slides with the plunger guide fastened to the outer tube, the plunger attached to the core coil that is pulled out from the outer tube, and the plunger is projected and retracted to the support part (attachment). Proposed with a plunger outer cylinder that is attached and supported, and a drain plug device that absorbs the impact by the elastic force of the shock absorber spring when a shock absorber spring is incorporated in the plunger and the shock is applied to the drain plug However, the number of parts is large, the mechanism is complicated, and assembly is difficult.

  An object of the present invention is to provide a drain plug operation mechanism excellent in ease of confirmation that the drain plug is in an open state. Moreover, it is desirable that the present invention is further excellent in preventing buckling of the inner cable due to an impact on the drain plug.

  The present invention includes a drainage portion provided at a drainage position, an operation portion provided apart from the drainage portion, and a control cable that connects a drainage plug provided at the drainage portion and a button provided at the operation portion. The drain plug operation mechanism is provided, wherein the control cable has an inner cable and an outer casing, and the inner cable has its operation unit side end fixed fixed to the operation unit, and the drain unit side end is drained. The outer casing is connected to the button, the end on the operation unit side is connected to the button, the end on the drain side is fixed to the drain, and the end on the operation unit side of the outer casing is connected to the inner cable. The drain plug operation mechanism is configured such that the drain plug opens and closes when moved relative to each other.

By configuring the drain plug operation mechanism of the present invention as described above, it is possible to imagine an operation in which the drain plug is pushed into the closed state when the button is pushed in, and the drain plug is plugged in when the button is returned. Since it can be imaged to return from the state to the open state, there is no need to actually check whether the state is closed or open. Therefore, even when the visibility is poor due to steam, when the glasses are cloudy, or when the glasses are removed, it is possible to easily recognize whether the state is closed or open.

  Further, the drain plug operation mechanism of the present invention is configured such that when the button is pushed in by a pushing operation, the drain plug is in a closed state, and when the button is projected by a return operation, the drain plug is projected. By configuring the drain plug operation mechanism to be in the open state in the form of a plug, when the button becomes convex due to the return operation, the drain plug becomes convex to be in the open state Thus, the convex state of the drain plug can be imaged from the convex state of the button, and the open / closed state of the drain plug can be recognized by visually recognizing the button state, and the movement of the button and the drain plug Because it is synchronized, it is easy to check even for blind people.

  Further, the drain plug operation mechanism of the present invention includes a drain plug operation mechanism that is held in a convex shape movable in the pushing direction by the biasing force of the biasing member when the button is returned to the return state by the return operation. As a result, when the button is in the return state, even if the drain plug is shocked by being held in a convex shape that is movable in the pushing direction, the drain plug is pulled into the closed state by the shock. In this case, since the button moves in the pushing direction and the impact is reduced, the inner cable is prevented from buckling.

It is a schematic sectional drawing of an example of the drain plug operation mechanism concerning this invention. It is an assembly drawing of the latch mechanism part of FIG.

The upper holder 341 and the lower holder 345 include a combined outer cap 344 and a curlack gear part 342 in the inner space, and four projecting parts 3421 of the calrack gear part 342 are projected at the tip part of the upper holder 341. The curlack gear portion 342 and the outer cap 344 are included so as to pass through the hole 3413 and protrude from the upper holder 341 so as to be slidable from the distal end direction of the upper holder to the proximal end direction of the lower holder 345.

  The outer casing 41 is fixed by crimping the outer cap 344 to the end portion on the operation portion side, and the small diameter portion 3441 is press-fitted into a hole provided at the base end of the curl rack gear portion 342, so that the outer cap 344 is culled. The rack gear portion 342 is fixed. Further, the engaging portion 3422 provided in the vicinity of the tip of the protruding portion 3421 of the curlac gear portion 342 engages with the button engaging portion 311 provided on the inner side of the button 31, so that the button 31 and the callac gear portion 342 are connected. It is fixed. That is, the outer casing 41 is connected to the button 31 via the outer cap 341 and the callac gear portion 342, and slides inside the latch mechanism portion 34 following the movement of the button 31.

  On the other hand, in the drainage section 2, the inner cable 42 penetrates from the drain plug-side outer cap 21 and slides in the axial direction of the inner cable 42 at the drainage section side end 44, which is the end of the outer casing 41 on the drainage section side. A drain plug-side outer cap 21 is provided so as to be movable. Since the drain cap-side outer cap 21 is engaged with the cable fixing member 22 fixed to the drain pipe 5, the drain portion-side end 44 of the outer casing 41 does not move to the drain portion 2 in the drain portion 2. It is fixed.

  The drain plug-side outer cap 21 includes a cylindrical pin guide portion 211 in which the pin 23 is slidably disposed in the axial direction. The outer casing fixing portion 212, the inner cable through hole 213, and the pin guide portion 211 The central axis is disposed so as to coincide with the central axis of the drain plug-side outer cap 21.

  The pin 23 disposed in the pin guide portion 211 of the drain plug-side outer cap 21 has a cylindrical shape with a closed tip, and includes an inner cable housing portion 231 in which the tip of the inner cable 42 is housed. When the pin 23 is disposed in the pin guide portion 211, the tip of the inner cable 42 penetrating the inner cable through hole 213 extends from the inner cable through hole 213 and is accommodated in the inner cable accommodating portion 231. . The drain plug-side outer cap 21 is attached to the cable fixing member 22 so that the pin 23 accommodated in the pin guide portion 211 can move in the direction of the drain plug from the cable fixing member 22. The cable fixing member 22 includes a cylindrical portion 221 that is in close contact with the inside of the drain pipe EX, and a fixing portion 222 to which the drain plug-side outer cap 21 is fixed is formed at the center thereof. A fin 223 is connected between the cylindrical portion 221 and the fixed portion 222, and the fin 223 also functions as a dust removal device that entangles dust such as hair and lint.

  Inside the drain pipe EX, a drain plug support member 25 that slidably supports the drain plug 24 is fixed adjacent to the cable fixing member 22. The drain plug support member 25 has a cylindrical main body portion 252 having a through-hole 251 in which the convex portion 241 of the drain plug 24 slides, and a fixing that protrudes from the outer wall surface of the main body portion 252 and is fixed to the inner surface of the drain pipe EX. Blade 253 for use. Four fixing blade portions 253 are provided at equal intervals in the circumferential direction of the main body portion 252. However, the number is not limited to this, and the number of fixing blade portions 253 can be fixed to the main body portion 252 and the drain plug 24. Can do. In addition, the fixing blade portion 253 has a dust removing function for entwining dust such as hair and lint.

  The drain plug 24 includes a disk-shaped lid portion 242 that closes the opening of the end portion of the drain pipe EX, and a convex portion 241 that protrudes in a direction orthogonal to the lid portion 242 from the center of the lid portion. A concave pin connection portion 243 to which the pin 23 is connected is provided at the end of the drain plug 24 opposite to the lid portion 242 of the convex portion 241. The front end side of the pin 23 is inserted and connected to the convex portion 241. The pin 23 and the pin connection portion 234 may be connected so that they cannot be pulled out below a certain force due to the frictional force caused by the fitting. You may make it prevent. The drain plug operation mechanism in FIG. 1 employs a friction structure. Thus, by comprising so that the drain plug 24 and the pin 23 can be attached or detached, a user can work easily, without the drain plug 24 getting in the way at the time of a maintenance or cleaning. As described above, since the pin 23 and the pin connection portion 243 of the convex portion 241 are connected, the drain plug-side end portion 421 of the inner cable 42 is connected to the drain plug 24. The drain plug 24 can be opened and closed by being pushed and pulled by the cable 42 and moving.

Next, the drain plug opening / closing operation of the drain plug operation mechanism 1 will be described. The button 31 provided in the operation portion 3 of the drain plug operation mechanism 1 is engaged with the protrusion 3421 and the engagement portion 3422 of the car rack gear portion 342, and the button 31 is pushed in with the operator's finger or the like by the pushing operation. When pushed in the direction, the callac gear portion 342 engaged with the button 31 also moves in the pushing direction, and the outer cap 344 connected to the callac gear portion 342 also moves in the pushing direction. At this time, the button 342 is held in the pushed state by the latch mechanism 34, and the position of the outer cap 344 is also held while moving downward in FIG. At this time, the position of the outer cap 344 is downward because the cable end 43 which is the end of the inner cable 42 on the operation portion side does not move relative to the bathtub flange 51 and is fixed in the operation portion 3. As a result, the end of the outer casing 41 on the operation unit side slides downward on the inner cable. That is, the outer casing 41 moves relative to the inner cable, and the distance from the cable end 43 to the outer cap 344 is increased.

Here, since the lengths of the inner cable 42 and the outer casing 41 are constant, respectively, the distance from the operation unit side end of the outer casing 41 to the cable end 43 is increased by the length on the drain plug side. The distance from the drain side end 44 of the outer casing 41 to the drain plug side end 421 of the inner cable 42 is shortened, and the inner cable 42 protruding from the drain plug side outer cap 21 is drawn into the outer casing 41. Become. In the drain plug 2, the inner cable 42 is drawn into the outer casing 41, and the drain plug side end 421 of the inner cable 42 moves downward in FIG. 1, so that the pin 23 also moves downward in FIG. 1. Further, the downward movement of the pin 23 causes the drain plug 24 to also move downward, and the drain plug 24 becomes a plug-like body.

When the button 31 held in the pushed state is pushed again by the pushing operation, the rack gear portion 342 connected to the button 31 is pushed, and the pushed state of the held rack gear portion 34 is released by the function of the latch mechanism portion 34. The As a result of this return operation, the curlack gear portion 342 is moved and held in the upward direction in FIG. 1, and the outer cap 344 is also moved and held in the upward direction in FIG. Here, the position of the cable end 43 of the inner cable 42 with respect to the bathtub flange 51 does not move and is fixed in the operation unit 3 so that the position of the outer cap 344 moves upward. 41 moves relative to the inner cable, and the distance from the cable end 43 to the outer cap 344 becomes shorter. Here, since the lengths of the inner cable 42 and the outer casing 41 are constant, respectively, the distance from the operation unit side end of the outer casing 41 to the cable end 43 is reduced by the amount on the drain plug side. The distance from the drain part side end 44 of the outer casing 41 to the drain plug side end 421 of the inner cable 42 becomes long, and the inner cable 42 protrudes from the drain plug side outer cap 21. In the drain plug portion 2, the inner cable 42 protrudes from the drain plug-side outer cap 21, and the drain plug-side end portion 421 of the inner cable 42 moves upward in FIG. Further, the upward movement of the pin 23 causes the drain plug 24 to also move upward, so that the drain plug 24 becomes a plug-like body. When the drain plug 24 is in the open state, the drain plug 24 becomes convex above the drain plug 24. Therefore, when the button 31 is convex by the return operation, the drain plug 24 is convex and opened. It becomes plugged. By being able to perform such an operation, when the button 31 becomes convex by the return operation, the drain plug becomes convex and becomes an open state, so that from the convex state of the button 31. The convex shape of the drain plug can be imaged, and the open / closed state of the drain plug can be recognized by visually recognizing the state of the button. Confirmation is easy even for a free person. Further, the button 31 held in the pushed-in state by the push-in operation is held so as to be in a substantially smooth state with the bathtub flange 51, so that the pushed-in state of the button 31 and the closed state of the drain plug 24 are substantially the same. Since it is in a smooth state, in addition to the button 31 and the drain plug 24 being convex in the open state, it is possible to imagine a substantially smooth state even in the closed state. Can be recognized more easily.

  When the button 31 becomes convex due to the return operation, the drain plug operation mechanism of FIG. 1 is mounted on the outside of the outer casing, accommodated inside the lower holder 345, and the upper end is the outer cap. The coil spring 35 is connected to the 344 and has a lower end connected to the retaining portion 3451. By providing the coil spring 35, when the holding state of the button 31 is released by the function of the latch mechanism portion 34 by the return operation, the outer cap 344 is moved upward by the coil spring 35, and the outer portion is moved by the coil spring 35. The cap 344 is held in a state of being moved upward in a floating state. The coil spring 35 holds the button 31 in a convex shape movable in the push-in direction by the urging force of the coil spring 35 when the button 31 is returned to the return state by the return operation. By forming such a convex shape movable in the pushing direction and being held in a floating state, the outer cap 344 is also held in a movable state. When the outer cap 344 is movable, an external force is applied to the drain plug such as a user stepping on the drain plug 24 that has been opened or dropping a heavy object such as a shampoo bottle onto the drain plug 24. When added, the inner cable 42 also moves downward in FIG. 1 following the movement of the drain plug 24 downward in FIG. The inner cable 42 moves so as to be drawn into the outer casing 41 because the drainage portion side end 44 of the outer casing 44 is fixed to the drainage portion. Here, although the distance between the drainage portion side end 421 of the inner cable 42 and the drainage portion side end 44 of the outer casing 44 is shortened, the operation portion side end of the outer casing 41 is held movably. Therefore, the distance between the cable end 43 fixed by the outer cap 344 moving downward and the outer cap 344 of the outer casing 41 can be increased. Therefore, even when a downward external force is applied to the drain plug 24, the outer cap 344 can move downward against the urging force of the coil spring 35 that holds the button 31 in a convex state. In this case, even if the inner cable 42 moves downward due to external force, the inner cable 42 is pulled into the outer casing 41, so that buckling occurs between the drain plug-side end 421 of the inner cable and the drain plug-side end 44 of the outer casing. There is no. That is, the button 31 moves in the pushing direction and the impact of the external force applied to the drainage portion 2 is alleviated, so that the inner cable is prevented from buckling.

  The inner cable 42 used in the drain plug operation mechanism in FIG. 1 is not particularly limited as long as it can be used for remote control of the drain plug. For example, a twisted wire obtained by twisting a plurality of metal wires is used. Although it can employ | adopt, the wire which can transmit an operating force mechanically to an axial direction can be employ | adopted widely. As the outer casing 41, for example, an outer casing having a structure in which one or a plurality of metal wires are embedded along the axis inside the main body can be adopted. However, the outer casing 41 can be used for remote operation. For example, there is no particular limitation.

  The coil spring 35 is also an urging member that can be held in a convex shape that allows the button 31 to move in the pushing direction by the urging force of the urging member when the button 31 is returned to the return state by the return operation. If so, the outer cap 344 connected to the button 31 is movable, so that it is possible to prevent the inner cable from buckling even when an external force is applied to the drain plug 24. The latch mechanism 34 is not particularly limited as long as it can perform the pushing operation and the returning operation as described above, and may be arranged so that the pushing operation and the returning operation as described above can be performed by a known method. That's fine. Further, the attachment position of the urging member is not particularly limited as long as the button 31 can be held in a convex shape movable in the pushing direction.

  INDUSTRIAL APPLICABILITY The present invention is provided in a container for accumulating water, such as a bathtub, a wash bowl, and a sink, and can be used as a drain plug operation mechanism that can drain water in the container by opening and closing.
