Abstract

<P>PROBLEM TO BE SOLVED: To drain water by turning an operating lever by a slight angle. <P>SOLUTION: A horizontal turning shaft 11 of a tank 1 is provided with an arm 12, and the vertically turnable operating lever 20 is provided in front of the turning shaft 11 and connected through a turning force transmission mechanism. The operating lever 20 is maintained such that its front end 20a faces the front side of the tank 1 in the azimuth around the axis of the turning shaft 11 in a cut-off state. The turning shaft 11 is turned around the axis by turning the operating lever 20, and the turning angle of the turning shaft 11 becomes larger than the turning angle of the operating lever 20 by the action of the turning force transmission mechanism. In this manner, the turning shaft 11 can be turned at an angle large enough to drain water in the tank 1 by turning the operating lever 20 by the slight angle. Furthermore, in the case of enclosing the tank 1 in a cabinet C, the front face of the cabinet C has only to be provided with an opening corresponding to the stroke of the operating lever, which does not impair the appearance. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a toilet tank water tank device for flush toilets.

  As shown in FIGS. 9 (a) and 9 (b), water is poured into a tank 1 attached to the toilet A through a stop cock 2, as shown in FIGS. 9 (a) and 9 (b). When water accumulates in the tank 1, the floating ball 3 rises and the valve of the ball tap 4 is closed, so that water supply to the tank 1 is stopped.

  A drain valve 8 connected to the toilet A connected to the bottom of the tank 1 is provided with a float valve body 7. The float valve body 7 has a dimension a in the lateral direction (FIG. 9A). It is connected via a chain 9 to the bent inner end 11a of the rotating shaft 11 penetrating in the width direction shown. The inner end 11a is normally maintained in the downward direction shown in the figure. By rotating the operating lever 10 provided on the outer end 11b of the rotating shaft 11 in the front-rear direction in the figure, the rotating shaft 11 is moved. The bent inner end 11a is turned upward by turning around the axis. The float valve body 7 is pulled up by this rotation, and the drain valve 6 at the upper end of the drain port 8 is opened to drain water toward the toilet A. When the operating lever 10 is released, the pivot shaft 11 returns to the original downward state, and the float valve body 7 also descends. After that, when water is accumulated in the tank 1 to some extent, the float valve body 7 is moved by the pressure of the water. The drain valve 6 is completely closed to stop the discharge. And if the floating ball 3 detects the rise in the water level in the tank 1 and a predetermined amount of water is secured, the water injection is stopped.

  For example, when storing a tank in a cabinet in order to improve the aesthetics in the toilet, adopting the conventional tank structure shown in FIG. 9 in which a lever is arranged on the side of the tank, the lever is placed in the cabinet together with the tank. Therefore, the lever cannot be operated unless the cabinet is opened and closed (see FIG. 10A). The operation lever is desirably provided on the front surface of the cabinet.

  Therefore, in order to arrange the operation lever on the front surface of the cabinet, a method of providing the rotation shaft in the front-rear direction of the tank (the depth direction indicated by the dimension b in FIG. 9A) and pulling the operation lever to the front surface of the cabinet is also considered. It is done. However, if the pivot shaft is provided in the front-rear direction, the pivot shaft must be positioned immediately above the discharge port at the bottom of the tank, so that the operation lever is positioned immediately behind the toilet bowl. For this reason, when the toilet seat or toilet lid is opened, the lid or the like interferes with the lever, making operation difficult. It is desirable that the operation lever be arranged slightly to the side avoiding the rotation range of the toilet seat and toilet lid.

In Patent Document 1, another rotating shaft in the front-rear direction orthogonal to the rotating shaft is provided so as to penetrate the inside and outside of the tank with respect to the rotating shaft in the horizontal direction of the tank, and both of them are turned and transmitted by the transmission means ( A technology is disclosed in which a float valve body can be moved up and down on the front surface of a tank by connecting via a bevel gear or the like and attaching a lever to the front end portion of the pivot shaft in the front-rear direction.
JP 2004-1116015 A

  However, the structure shown in Patent Document 1 requires two shafts for transmitting the rotational force, and the structure of the diverting transmission means for transmitting the rotational force in different directions is interposed between both rotating shafts. As a result, it becomes a factor of high cost during manufacturing, and subsequent maintenance becomes difficult, and this type of tank structure may not be adopted. In addition, since the drive mechanism is disposed in the tank, there is a concern that moisture may touch a movable part such as a gear and cause a failure.

  In view of this, in the configuration having the single horizontal rotating shaft, as shown in FIG. 10B, a long operating lever 10 is attached to the rotating shaft, and the tip of the operating lever 10 is moved forward. A method is conceivable in which the projection can be operated on the front surface of the tank 1. However, if the operating lever 10 is lengthened, the vertical stroke of the lever 10 becomes longer. For example, as shown by the arrows in the figure, the operating lever 10 is rotated upward or downward at a large angle (stroke). Must be moved.

  For this reason, when the tank 1 is housed in the cabinet C, the operation lever 10 rotates from the water stop state (neutral state) to the drain direction and interferes with the front plate of the cabinet C. A recess or opening as shown in the figure must be provided in the rotation range. Since the recess and the opening become very large when the lever is long, the aesthetic appearance of the cabinet C is impaired, which is not preferable. Further, even when the tank 1 is not stored in the cabinet C or the like, it is not preferable because the operation is troublesome if the stroke of the operation lever is long.

  Therefore, an object of the present invention is to reduce the rotation angle of the operation lever necessary for drainage in the toilet tank water tank device in which the operation lever is pulled out to the front of the tank.

  In order to solve the above-mentioned problem, the present invention provides a rotational power transmission mechanism comprising an axial radial arm provided on a rotary shaft and an operation lever provided so as to be rotatable in the vertical direction separately from the rotary shaft. Thus, the rotation angle of the rotation shaft is made larger than the rotation angle of the operation lever.

  In this way, the arm can be rotated at a relatively large angle with respect to the rotation of the operation lever at a slight angle. Therefore, the operation corresponding to the rotation angle of the rotation shaft necessary for opening the drain outlet is performed. The rotation angle (stroke) of the lever can be reduced. For this reason, the operation lever pulled out forward can be operated with a small stroke.

  Since this invention was made above, while ensuring the predetermined rotation angle of the rotation axis required for drainage, the rotation angle of the operation lever can be reduced.

  As a specific embodiment of the above means, in a toilet bowl cleaning water tank apparatus which can drain water stored in the tank by rotating a rotating shaft disposed in the lateral direction of the tank around the axis. The moving shaft is provided with an arm that rotates about the axis together with the rotating shaft, and an operation lever that is rotatable in the vertical direction is provided in front of the rotating shaft. The operating lever and the arm are connected via a rotational power transmission mechanism, and by rotating the operating lever, the rotational shaft rotates about the axis via the rotational power transmission mechanism. As a result, the rotation angle of the rotation shaft is made larger than the rotation angle of the operation lever. If it does in this way, a rotation axis | shaft can be rotated by the big angle which can drain the water of a tank by rotation of the operation lever of a slight angle. For this reason, the rotation range (stroke) of the operation lever is reduced, the operation is simplified, and the space required for the arrangement of the operation lever can be reduced.

  In addition, if the tank is stored in the cabinet behind the toilet and the front end of the operation lever always protrudes to the front of the cabinet, the rotation angle of the operation lever required to drain the water in the tank is small. It is sufficient to provide a slight length of vertical opening, slit, etc. corresponding to the stroke of the operation lever on the front of the cabinet. For this reason, the beauty of the cabinet is not impaired.

  The operation lever has a front end at the front of the tank 1 by a biasing force of a weight or a spring provided on the arm or the operation lever in an orientation around the rotation shaft in a state where the tank is stopped. It is possible to adopt a configuration that faces the screen. This is convenient because it is not necessary to return the operating lever to its original state after the drainage operation, and there is no need to provide means for locking the operating lever at a predetermined rotational position. As the biasing method, for example, a weight or a spring may be provided on the arm to bias the rotating shaft, or a weight or a spring may be provided on the operation lever for biasing. Moreover, you may use both energizing methods together. In this way, by indirectly energizing the rotating shaft via the arm or operation lever, it is possible to detach components regardless of the rotating shaft itself or the device in the tank. It becomes convenient to.

  As the rotating power transmission mechanism, a well-known four-bar crank mechanism can be used, and a member having a slider function may be used in a node portion constituting the four-bar crank mechanism. For example, as a specific example of a four-bar crank mechanism having a slider function, the operation lever and the arm are provided so as to overlap each other in the axial direction of the rotation shaft, and the operation lever is provided with a long groove in a direction gradually away from the rotation center. And the longer groove is made closer to the axis of the rotation shaft as it approaches the rotation center of the operation lever. There is a configuration in which a pin is provided on the arm, the pin is accommodated in the long groove, and is movable in the long groove. In this way, the rotational power transmission mechanism can be realized with a simple configuration, and the rotation angle of both of them can be freely set by selecting the form and position of the groove in the operation lever and the pin position in the arm.

  Further, in the configuration using the rotational power transmission mechanism via the long groove and the pin, the rotation shaft can be rotated in both directions with the axis around the axis in a state where the tank is stopped, The drain outlet can be opened even if it is rotated in any direction from the water stop state. The long groove of the operation lever is formed such that the position of the pin in the water stop state of the rotation shaft and the position of the pin in the drain opening state are different from the rotation center of the operation lever. In this case, when the operation lever is rotated at the same angle in the opposite direction from the position of the operation lever corresponding to the water stop state of the rotation shaft, the rotation in each direction is not performed. A difference occurs in the rotation angle of the corresponding arm and rotation shaft with respect to the movement. By selecting the rotation direction of the operation lever based on the difference in the rotation angle, the amount of discharged water for toilet flushing can be used differently.

  One embodiment will be described with reference to FIGS. As shown in FIG. 6, the toilet tank water tank device of this embodiment is a device in which the entire device is accommodated in a cabinet C provided behind the toilet in the toilet.

  The structure of the apparatus is that a float valve body 7 that opens and closes a drain port 8 connected to a toilet A connected to the bottom of the tank 1 and a tank 1 connected to the float valve body 7 via a chain 9 in the lateral direction Since the structure of the rotating shaft 11 penetrating the shaft is the same as that of the conventional example, the description thereof will be omitted, and a mechanism for rotating the rotating shaft 11 about the axis will be described below.

  As shown in FIG. 3, a bracket 30 is attached to the side surface of the tank 1 housed in the cabinet C, and the outer end 11 b of the rotating shaft 11 protruding from the tank 1 is a hole in the bracket 30. 32 is inserted. A fan-shaped arm 12 that rotates about the axis together with the rotation shaft 11 is provided at the outer end 11 b of the rotation shaft 11. Both of them are fixed to each other by an outer end 11b of the rotating shaft 11 in a hole 14 provided at the rotation center of the arm 12 forming a fan shape and fixed by a pin 12a.

  As shown in FIG. 4, a pin 13 having an axial direction parallel to the rotation shaft 11 is attached to the arm 12 so as to be rotatable around the axis. ing. A weight 15 is provided from the vicinity of the tip of the other bus bar to the vicinity of the center of the circumference, and the arm 12 is supported by the tank 1 and the bracket 30 so as to be rotatable together with the rotating shaft 11. At the same time, due to the effect of the weight 15, the rotating shaft 11 is urged around the axis in a direction to return to the position shown in FIG. At the position of the arm 12 shown in FIG. 4, the rotating shaft 11 is in a water stop state in which the float valve body 7 is lowered to close the drain port 8. That is, the inner end 11a of the rotating shaft 11 shown in FIG. 9 is in a downward state.

  The bracket 30 attached to the tank 1 is provided with a lever rotating shaft 21 located slightly forward and slightly above the rotating shaft 11 via a bearing 31, and the lever rotating shaft 21 is attached to the lever rotating shaft 21. An operation lever 20 is attached that rotates about the axis of the lever rotation shaft 21 around the axis. A front end 20a of the operation lever 20 is inserted through a vertical slit 34a of a reinforcing bracket 34 attached to an opening 35 provided on the front plate of the cabinet C and protrudes forward, and a cover 20b is attached to the front end 20a. It has been. Further, a contact plate 16 is provided on the tank 1 side of the operation lever 20, and the contact plate 16 is formed at the upper and lower ends thereof with a protrusion 16 b shown in the figure fitting into the hole 20 c of the operation lever 20. The claws 16a, 16a are fixed so as to rotate integrally with the operation lever 20 with the upper and lower edges of the operation lever 20 interposed therebetween.

  The operation lever 20 is similarly provided with a sub-lever 22 that rotates around the lever rotation shaft 21. As shown in FIG. 3, the sub-lever 22 has an upper end 22a in a cross-sectional shape of the operation lever 20. Are connected to each other to rotate integrally. The sub-lever 22 is provided so that the tip 22b side thereof overlaps with the arm 12 in the axial direction of the rotating shaft 11 with a gap between the sub-lever 22 and the arm 12 at the overlapping portion of the operating lever 20 with the arm 12. Is formed with a long groove 23 in the axial direction of the lever rotation shaft 21.

  The long groove 23 approaches the axial center of the rotating shaft 11 as it approaches the axial center of the lever rotating shaft 21, and is farther from the rear end 23 a close to the lever rotating shaft 21 to the lever rotating shaft 21. It is formed slightly bent in the middle of reaching the tip 23b. For this reason, the long groove tip 23b, which is the position of the pin 13 close to the neutral state of the rotating shaft 11 shown in FIG. 4, and the position of the rear end 23a of the long groove 23 are different from the axis center of the lever rotation shaft 21. It is formed to be oriented. Specifically, as shown in FIG. 4, when the pin 13 is positioned at the long groove tip 23 b, the position of the pin 13 is a direction connecting the axis center of the lever rotation shaft 21 and the axis center of the rotation shaft 11. On the other hand, the rotation shaft 11 has an angle γ around the axis center.

  The pin 13 of the arm 12 is accommodated in the long groove 23. As shown in FIG. 3, the pin 13 has annular flanges 13 a and 13 a on both sides thereof, so that both side edges in the width direction of the long groove 23 are fitted between the flanges 13 a and 13 a, and the long groove 23 It is easy to be guided along the length direction. Since the insertion portion 23c having a slightly enlarged diameter is formed at the rear end 23a of the long groove 23, the pin 13 is accommodated from the insertion portion 23c.

  The long groove 23 is set so that the distance from the axis center of the rotating shaft 11 differs according to the distance from the axis center of the lever rotation shaft 21, so that the sub lever 22 together with the operation lever 20 is connected to the lever rotation shaft. By rotating around 21, the pin 13, which is always at a fixed distance from the axis center of the rotation shaft 11 that is the rotation center of the arm 12, moves in the long groove 23 of the sub-lever 22 and rotates along with the movement. The shaft 11 is rotated around the axis. The sub lever 22, the long groove 23, and the pin 13 provided on the arm 12 constitute a rotational power transmission mechanism that transmits the rotational power of the operation lever 20 to the rotation shaft.

  As shown in FIG. 3, a pair of spring cases 24 and 26 each having a circular inner space are attached to the lever rotating shaft 21 of the operating lever 20. A torsion coil spring 25 is accommodated. In the mounting method, holes 24c and 26c are formed in the pair of spring cases 24 and 26, respectively. The holes 24c and 26c are provided with the hole 16c of the contact plate 16 and the hole 20c of the operation lever 20, respectively. The lever rotating shaft 21 is inserted together with the hole 22 c of the sub lever 22 and fixed to the bracket 30. Further, the sub lever 22 and the spring case 26 are fixed via screws 27 inserted through the holes 22d and 26a, respectively.

  As shown in FIG. 3, the spring case 24 is provided with a fixing piece 24 a that protrudes toward the tank 1, and the fixing piece 24 a is fitted into the fixing hole 33 of the bracket 30. , 26 are immobile around the lever rotation shaft 21. Further, the torsion coil spring 25 is fitted into arc-shaped guides 24b and 26b provided in the two spring cases 24 and 26, and the whiskers 25a and 25b of the spring 25 are respectively guided as shown in FIG. It is locked to the end of 26b.

  When the operation lever 20 is operated to rotate the rotation shaft 11, the rotation shaft 11 is in the water stop state as shown in FIG. 4, and the operation lever 20 is in the water stop state. Is maintained in the horizontal direction corresponding to. This state is a neutral state. The pivot shaft 11 can be pivoted in both directions up and down across this neutral state, and the float valve body 7 in the tank 1 is lifted to raise the drain port 8 no matter which direction the neutral shaft is pivoted. Can be opened.

  When the operation lever 20 in the neutral state is rotated upward in the direction indicated by the arrow in FIG. 1, the operation lever 20 is rotated from the chain line as indicated by the solid line. By this rotation, the sub lever 22 integrated with the operation lever 20 rotates in the left direction in the figure. As the operation lever 20 rotates, the upper claw 16a of the contact plate 16 contacts the stopper 36 of the bracket 30, so that the operation lever 20 stops rotating in the contacted state. At this time, the pin 13 of the arm 12 moves in the long groove 23 of the sub-lever 22 from the long groove front end 23b to the long groove rear end 23a. Rotate to. Since the rotation angle β of the arm 12 and the rotation shaft 11 is in a relationship of α <β with respect to the rotation angle α of the operation lever 20, it is compared with the rotation angle of the rotation shaft 11 necessary for drainage. Thus, the rotation angle of the operation lever 20 corresponding to the rotation angle is relatively small.

  Further, by rotating the operation lever 20 upward, as shown in FIG. 1, one whisker 25b of the torsion coil spring 25 is pushed rightward in the drawing by the guide 26b. The operating lever 20 is urged in a direction to return to the neutral state by the elastic force. Therefore, when the hand holding the operation lever 20 is released, the operation lever 20 returns to the neutral state shown in FIG. 4 and maintains that state. Further, the urging force by the weight 15 provided on the arm 12 also functions to simultaneously return the operation lever 20 and maintain the state.

  On the other hand, when the operation lever 20 in the neutral state is rotated downward as shown in FIG. 5, the sub lever 22 integrated with the operation lever 20 is rotated rightward in the drawing. At this time, the pin 13 of the arm 12 moves in the long groove 23 of the sub-lever 22 from the long groove front end 23b to the long groove rear end 23a. Rotate around. At this time, the effect of increasing the rotation angle of the arm 12 and the rotation shaft 11 with respect to the rotation angle of the operation lever 20 is the same. Similarly, the claw 16a below the contact plate 16 contacts the stopper 36 of the bracket 30. Due to the contact between the claw 16a and the stopper 36, the turning angle of the operation lever 20 in the vertical direction is set to be the same angle both when it is turned upward and when it is turned downward. ing.

  In this operation, as shown in FIG. 4, the long groove 23 is bent in the vicinity of the long groove front end 23b, and is at an angle with respect to a line connecting the axis center of the lever rotating shaft 21 and the position of the pin 13 at the long groove rear end 23a. γ is eccentric. Therefore, the rotation angle of the arm 12 and the rotation shaft 11 when the operation lever 20 is rotated upward is 2γ more than the rotation angle when the operation lever 20 is rotated downward. It will only be big. For this reason, when the operation lever 20 is rotated upward, the inner end 11a of the rotation shaft 11 shown in FIG. 9 rotates at a larger angle and is connected via the chain 9. 7 is greatly increased, so the amount of drainage is increased. Further, when the operation lever 20 is rotated downward, the float valve body 7 rises with a slightly lowering height, so that the amount of drainage water is relatively reduced. That is, the amount of washing water can be switched depending on the rotation direction of the operation lever 20.

  Note that when the operation lever 20 is rotated downward, the operation of the operation lever 20 being urged in the direction of returning to the neutral state is the same as that when the operation lever 20 is rotated upward. Omitted (see FIG. 5).

  The operating lever 20 is attached to the front of the rotating shaft 11, that is, its front end 20a protrudes to the front of the tank 1 and can be operated from the front side of the tank 1. A lever rotation shaft 21 that supports 20 in a vertically rotatable manner may be provided in the tank 1 as in this embodiment, or may be provided in the cabinet C. Further, it may be provided on a fixed frame different from the tank 1.

  As the second embodiment, a four-bar crank mechanism shown in FIG. 7 may be employed. In FIG. 7, only the configuration of the four-bar crank mechanism that constitutes the rotating power transmission mechanism is illustrated, and the tank 1, the cabinet C, and the like are not illustrated. Further, the operation lever 20 shown in the figure is schematically shown to show the operation state of the rotating shaft 11, the arm 12, and the lever rotating shaft 21, and the shape thereof is appropriately modified or partially changed. It is assumed that the operation lever 20 is arranged in a state where the operation lever 20 faces forward from the rotation shaft 11 and can be rotated in the up-down direction by adding a necessary member.

  The movements of the rotation angle β of the rotation shaft 11 and the rotation angle α of the lever rotation shaft 21 corresponding to the rotation angle β shown in Example 1 are shown in FIG. This corresponds to rotation in the direction indicated by α ′. In the second embodiment, as in the first embodiment, a four-bar crank mechanism with a slider function is used, and the shape of the long groove 23 constituting the slider function is not bent halfway in the length direction. .

Similarly, as the configuration of the rotating power transmission mechanism using the four-bar crank mechanism having a slider function, the mechanisms shown in FIGS. 8A, 8B, and 8C may be employed. The explanation of the reference numerals in the figure is the same as in the case of the second embodiment, and the explanation is omitted. Moreover, as a structure of the four-bar crank mechanism which does not have a slider function, the aspect shown in FIG.8 (d) is employable, for example.
The turning force transmission mechanism is not limited to the above four-barrel crank mechanism, and turning the operating lever 20 causes the turning shaft 11 to turn around the axis via the turning force transmission mechanism. Needless to say, a known transmission mechanism can be employed as long as the rotation angle of the rotation shaft 11 is larger than the rotation angle of the operation lever 20.
