Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a toilet device having an opening / closing mechanism for gently closing a toilet seat and a toilet lid that are attached to a toilet body.

[0002]

[Prior Art]

 A seat-type flush toilet is equipped with a toilet seat only or a toilet seat and toilet lid that can be opened and closed. A structure has been conventionally used in which when the toilet seat and the toilet lid are closed, a resistance is applied to the rotation of the hinge mechanism so that the hinge mechanism operates gently. This mechanism serves to prevent the toilet seat or lid from hitting the toilet body and making noise when the toilet seat or lid is closed by hand. An example of a device provided with such a mechanism for opening and closing a toilet seat and a toilet lid is disclosed in Japanese Patent Application Laid-Open No. 1-90326 proposed by the present applicant.

Including those described in this publication, resistance is given when closing the toilet seat and the toilet lid to slow the movement when the toilet seat falls down, thereby preventing generation of impact noise and damage to members. Is the basic structure of the cushion mechanism of the toilet seat and the toilet lid. Since there are cases where only one of the toilet seat and the toilet lid is opened and closed, and where both of them are opened and closed at the same time, two pairs of hinge portions provided at the base end portions of the toilet seat and the toilet lid are referred to as 2 A structure in which each shock-absorbing mechanism is connected via a hinge shaft is generally adopted.

[0004]

[Problems to be solved by the device]

 As described above, in the case where the toilet seat and the toilet lid are provided, these two base end portions must be connected to the pair of cushioning mechanisms. For this reason, it is necessary to provide two shock absorbing mechanisms as parts, and the number of built-in parts is relatively large, so there is a limit in terms of cost reduction.

Further, although the shock-absorbing mechanism is a unitized and small-sized one, the shock-absorbing mechanism occupies a larger volume than a simple assembly in which the hinge shaft is simply connected to the toilet side. This can affect not only the toilet bowl but also the degree of freedom in the design of the toilet seat and toilet lid. In particular, in the case of a model in which the toilet seat or the toilet lid is integrally assembled with the sanitary washing device for local washing, the buffer mechanism unit is also provided in the casing of the sanitary washing device, so the nozzle device or the warm air fan is installed. It is easy to give an obstacle to the layout of other devices such as.

As described above, in the conventional structure, two cushioning mechanisms corresponding to the toilet seat and the toilet lid, respectively, are indispensable. Therefore, it should be improved in terms of design flexibility and cost. Is left.

The problem to be solved in the present invention is to enable the cushioning operation of the toilet seat and the lid with only one cushioning mechanism.

[0008]

[Means for Solving the Problems]

 The present invention is a toilet device comprising an opening / closing unit that connects a toilet seat and a toilet lid to the toilet body side in a freely openable and closable manner and provides resistance to movement when the toilet seat and the toilet lid are closed. Insert one hinge shaft connected to the opening / closing unit on the rotation fulcrum side, and in the toilet seat and toilet lid surrounding the hinge shaft, depending on the standing state and closed state of the toilet lid and toilet seat. A clutch mechanism for switching the connection to the opening / closing unit to the toilet lid side or the toilet seat side is provided, respectively.

As the clutch mechanism, it is possible to use a coil spring, one end of which is fixed to the toilet seat or the toilet lid, and which changes the tightened state of the hinge shaft according to the rotation thereof.

[0010]

[Action]

 The hinge shaft is used as a transmitter in order to provide resistance from the opening / closing unit when the toilet seat and toilet lid are tilted. At this time, since the toilet seat and the toilet lid may be opened and closed independently with one hinge shaft, one hinge shaft cannot be dedicated to either the toilet seat or the toilet lid. On the other hand, if a hinge mechanism is provided on the toilet seat and the toilet lid where the hinge shaft is inserted, and the connection to the opening / closing unit is switched from the toilet lid to the toilet seat side when the toilet seat and toilet lid are tilted, Both the lid and the toilet seat can provide resistance from the opening / closing unit with a single hinge shaft. Therefore, only one opening / closing unit connected to the hinge shaft is required, and the number of parts and the number of assembling steps can be reduced.

【Example】

 FIG. 1 is a perspective view showing the entire toilet device of the present invention.

In the figure, a toilet body 1 is fixed to a casing 2 for accommodating a washing water tank for supplying washing water to a ball portion and a functional portion for local washing, and the casing 2 is provided with a toilet seat 3 and a toilet. Each lid 4 is attached so as to be openable and closable. The toilet seat 3 and the toilet lid 4 are each provided with a pair of connecting seats 3a, 3b, 4a, 4b in the width direction of the base end portions thereof as in the conventional structure.

FIG. 2 is a schematic plan view showing how the toilet seat 3 and the toilet lid 4 are connected to the casing 2.

Connecting holes 3c and 4c are opened in the connecting seats 3a to 4b of the toilet seat 3 and the toilet lid 4, respectively, and the hinge shafts 5 and 6 are inserted through these connecting holes 3c and 4c. The hinge shaft 5 located on the right side in the drawing is passed through the connection holes 3c and 4c of the connection seats 3b and 4b, and then fitted into the holding seat 2a fixed in the casing 2 to be integrally connected. Then, with respect to the hinge shaft 5 fixed by the holding seat 2a, the connecting holes 3c and 4c are both restrained so that they can freely rotate.

One hinge shaft 6 is inserted into the connecting holes 3c, 4c of the connecting seats 3a, 4a on the left side in the drawing, and is connected to the opening / closing unit 7 provided in the casing 2. As the opening / closing unit 7, for example, the one having the structure described in Japanese Patent Application Laid-Open No. 1-90326 described in the section of the prior art can be used as it is. That is, the opening / closing unit 7 may have any structure as long as it can give resistance to the hinge shaft 5 when the toilet seat 3 and the toilet lid 4 are closed. In addition to the function for such a resistance load, the resistance may increase as the toilet seat 3 and the toilet lid 4 fall down.

The hinge shaft 6 connected to the opening / closing unit 7 is connected to the toilet seat 3 and the connecting seats 3 a and 4 a of the toilet lid 4 via a clutch mechanism. FIG. 3 is a view for showing this connecting structure, which is a cross-sectional view taken along a plane including the axis of the hinge shaft 6 inserted into the connecting holes 3c, 4c, and is shown in (a) and (b) of FIG. FIG. 4 is a vertical sectional view taken along the lines AA and BB of FIG. 3, respectively.

As shown in FIG. 4, the hinge shaft 6 has a substantially oval cross-sectional shape having a straight portion on the outer peripheral surface, and has a flange 6a at one end that abuts against the side surface of the connecting seat 3a of the toilet seat 3. The end is inserted into the opening / closing unit 7 and connected to it. A cylindrical sleeve 8 is fitted and fixed to the outer circumference of the portion where the hinge shaft 6 is located in the connecting holes 3c and 4c, respectively. Then, coil springs 9 and 10 for clutches are arranged around these sleeves 8, respectively.

The coil spring 10 on the toilet lid 4 side is provided with an engaging claw 10a protruding outward at one end and an engaging piece 10b bent inward at the other end. Then, the engaging claw 10a is fitted into the holding groove 4d formed from the inner peripheral surface of the connecting hole 4c toward the outer side, and the locking piece 10b is inserted into the concave portion 8a recessed in the outer peripheral surface of the sleeve 8. Insert it. The coil spring 10 has an inner diameter that allows the outer peripheral surface of the sleeve 8 to be wound around with a gentle force in its natural state, and its winding direction is in the direction of closing the toilet lid 4 as can be seen from FIG. 4 (a). The coil spring 10 should be wound up when moving.

On the other hand, the coil spring 9 on the toilet seat 3 side is also provided with an engaging claw 9a and a locking piece 9b at both ends, and the engaging piece 9a is fitted into the holding groove 3d of the connecting hole 3c. At the same time, the locking piece 9b is fitted into the recess 8a of the sleeve 8. The winding direction of the coil spring 9 is, as can be seen from FIG. 4B, the winding direction of the coil spring 9 when the toilet seat 3 is moved in the closing direction. FIG. 5 shows a schematic view of the assembled postures of the coil springs 9 and 10 with respect to the sleeves 8 on the toilet seat 3 side and the toilet lid 4 side, respectively.

As shown in FIG. 3, the sleeve 8 having the coil springs 9 and 10 having such a winding direction on its peripheral surface is incorporated into the connecting holes 3c and 4c, respectively, and held by the bushings 3e and 4e. To be done. Therefore, the toilet seat 3 and the toilet lid 4 are connected to the hinge shaft 6 by the coil springs 9 and 10, respectively, and the coil springs 9 and 10 are integrated with the sleeve 8 by the change in the inner diameter caused by winding and unwinding. It can function as a clutch mechanism that rotates and slips.

In the illustrated example, the coil springs 9 and 10 are provided with locking pieces 9b and 10b at one end, respectively, and the sleeve 8 is provided with a recess 8a into which these locking pieces 9b and 10b are fitted. It is provided. Alternatively, one end of the coil springs 9 and 10 may be simply wound around the outer peripheral surface of the sleeve 8 as a free end. In this case, if the initial winding force is set appropriately, the sleeve 8 It can fulfill the clutch function with the surroundings.

In the above configuration, when both the toilet seat 3 and the toilet lid 4 are closed, the coil spring 9 is rotated counterclockwise in FIG. 4A and clockwise in FIG. 4B. , 10 is in a state in which the acting force is applied. At this time, only the coil spring 10 on the toilet lid 4 side tightens the sleeve 8 tightly, and the coil spring 9 on the toilet seat 3 side has a slippery relationship with the sleeve 8. Such a relationship can be realized by appropriately setting the positions of the fixing points of the coil springs 9 and 10 with respect to the sleeve 8 and the fixing points of the connecting holes 3c and 4c.

It should be understood that the magnitude of the spring constant and the amount of winding of the coil springs 9 and 10 should be determined so that the toilet seat 3 and the toilet lid 4 will not rise from the closed state. Further, as described above, in the case where the coil springs 9 and 10 have free ends in which the locking pieces 9b and 10b are not provided, if the initial winding force is appropriately set, the coil springs and It is possible to fulfill the clutch function of.

Here, when only the toilet lid 4 is started up, the coil spring 10 tightly winds up the sleeve 8, so the sleeve 8 also turns clockwise in FIG. 4A, and the coil spring 10 slips. The sleeve 8 stops rotating when it starts. After that, when the toilet lid 4 is rotated to the upright position, only the coil spring 10 is loosened, and the sleeve 8 and the hinge shaft 6 remain stopped. On the other hand, on the toilet seat 3 side, the hinge shaft 6 rotates counterclockwise in FIG. 4 (b) at the initial stage, but the coil spring 9 relatively increases the tightening force, and the toilet seat 3 closes. Maintained in a state. Therefore, when only the toilet lid 4 is erected, the tightening of the coil spring 10 on the toilet lid 4 side to the sleeve 8 is loosened, the sleeve 8 can freely rotate regardless of the coil spring 10, and the coil spring on the toilet seat 3 side can be rotated. 9 will fasten the sleeve 8 with a strong force.

When the toilet seat 3 is erected while the toilet lid 4 is upright, the coil spring 9 tightly tightens the sleeve 8, and at the same time as the toilet seat 3 rotates, the hinge shaft 6 moves through the sleeve 8 and 4 (b), when the coil spring 9 turns counterclockwise and the tightening of the coil spring 9 gradually loosens and starts to slip around the sleeve 8, the rotation of the hinge shaft 6 stops. Therefore, when the toilet seat 3 is erected, the tightening of the sleeve 8 by the coil spring 9 is loosened, while on the toilet lid 4 side, the hinge shaft 6 slightly rotates clockwise in FIG. The coil spring 10 comes to tighten the sleeve 8.

As described above, when the toilet seat 3 and the toilet lid 4 are erected, the sleeve 8 can freely move with respect to the coil spring 9 on the side of the toilet seat 3 and the coil spring 10 on the side of the toilet lid 4. Since it is tightened up, the hinge shaft 6 is united together with the toilet lid 4 and is in a rotatable state. Then, when the toilet seat 3 and the toilet lid 4 are erected, the opening / closing unit 7 functions so as not to give any resistance to the hinge shaft 6, and the toilet seat 3 and the toilet lid 4 are lightly pressed. Can be lifted.

Next, when only the toilet seat 3 is tilted from the standing state of the toilet seat 3 and the toilet lid 4, the coil spring 9 is looser with respect to the sleeve 8, so at the initial stage of tilting the toilet seat 3, the coil spring 9 9 slips around the sleeve 8. Therefore, when the toilet seat 3 starts to be tilted, the hinge shaft 6 does not start rotating, and remains stopped until the coil spring 9 is tightened strongly. When the coil spring 9 is sufficiently tightened, the hinge shaft 6 starts to rotate clockwise in FIG. 4B along with the movement of the toilet seat 3. On the other hand, when the hinge shaft 6 starts to rotate in this manner, the hinge shaft 6 rotates counterclockwise in FIG. 4A, and the coil spring 10 loosens with respect to the sleeve 8. Therefore, when the toilet seat 3 is tilted, the clutch using the coil spring 10 is disengaged, and the toilet lid 4 is kept in the upright position.

As described above, when the toilet seat 3 is tilted, even if the common hinge shaft 6 is used, the toilet lid 4 can be held in the standing posture regardless of the operation of the toilet seat 3. When the hinge shaft 6 rotates clockwise in FIG. 4 (b) through the sleeve 8 that is tightened by the coil spring 9, the hinge shaft 6 is connected to the opening / closing unit 7. , Receive resistance to the closing direction. Therefore, the toilet seat 3 can be gently seated on the toilet body 1 while receiving the resistance of the opening / closing unit 7 and can be closed quietly without generating an impact noise or the like.

Further, when the toilet lid 4 is tilted down when the toilet seat 3 is closed, the coil spring 9 on the toilet seat 3 side is tightening the sleeve 8, while the coil spring 10 on the toilet lid 4 side is It is loose with respect to the sleeve 8. Therefore, when the toilet lid 4 starts to be tilted, only the toilet lid 4 moves and the hinge shaft 6 does not rotate until the coil spring 10 sufficiently tightens the sleeve 8. Then, the hinge shaft 6 starts to rotate via the sleeve 8 only when the coil spring 10 tightens the sleeve 8 and the rotation can be transmitted as the toilet lid 4 falls. Therefore, the toilet lid 4 is connected to the opening / closing unit 7 via the hinge shaft, and receives the resistance of the opening / closing unit 7 and is gently placed on the toilet seat 3.

When both the toilet seat 3 and the toilet lid 4 are closed, the hinge shaft 6 rotates clockwise in FIG. 4B when the toilet lid 4 is tilted, so that the sleeve 8 on the toilet seat side is On the other hand, the coil spring 9 becomes loose. On the side of the toilet lid 4, the toilet lid 4 falls and the coil spring 10 tightly tightens the peripheral surface of the sleeve 8. This agrees with the situation when both the toilet seat 3 and the toilet lid 4 described above are closed.

Next, consider a case where the toilet seat 3 and the toilet lid 4 are upright and both of them are collapsed together.

When standing up, the coil spring 10 on the side of the toilet lid 4 tightens the sleeve 8, so when the toilet seat 3 and the toilet lid 4 start to be tilted at the same time, the hinge shaft 6 moves together with the toilet lid 4. Begins to rotate. On the other hand, since there is no tightening of the coil spring 9 to the sleeve 8 on the toilet seat 3 side, if the toilet lid 4 is pushed downward, it will move together with the toilet lid 4 in the closing direction. As the toilet lid 4 closes, the tightening of the coil spring 9 on the toilet seat 3 side to the sleeve 8 increases, so that the connection with the hinge shaft 6 gradually switches from the toilet lid 4 side to the toilet seat 3 side. Go Therefore, after the toilet lid 4 is closed, since the hinge shaft 6 is connected to the toilet seat 3 side, the toilet seat 3 gradually moves toward the closing direction while receiving the resistance of the opening / closing unit 7, and finally the toilet seat. Both the toilet lid 3 and the toilet lid 4 are placed on the toilet body 1.

Thus, when the toilet seat 3 and the toilet lid 4 are closed by the single hinge shaft 6, they can be independently switched to the connection / disconnection state with the opening / closing unit 7. Therefore, conventionally, two opening / closing units dedicated to the toilet seat 3 and the toilet lid 4 are required, but only one opening / closing unit 7 needs to be incorporated. Therefore, the space for installing the opening / closing unit 7 can be reduced, and the number of parts and the number of assembling steps can be reduced by half, so that the obstacle in terms of cost can be eliminated.

[0034]

[Effect of the device]

 In the present invention, the toilet seat and the toilet lid can be connected and used with only one opening / closing unit by one hinge shaft. Therefore, it is not necessary to provide a separate opening / closing unit for the toilet seat and that for the toilet lid as in the conventional case, and the number of parts and the number of assembling steps are reduced by half. In addition, the space for installing the opening / closing unit is also reduced, so the degree of freedom in designing the toilet seat, toilet lid, and toilet body is improved, and even if a cushioning mechanism is provided, there is no constraint on the design. ..
