Description

  The present invention relates to a toilet seat device provided with shock absorbing means during rotation.

  Conventionally, as a toilet seat device of this type, generally, a damper is installed on the pivot shaft of the toilet seat to reduce the rotational speed, thereby suppressing the sound generated when the toilet seat hits the toilet when the toilet seat is closed. There is one that can be closed smoothly (for example, see Patent Document 1).

  In addition, when an air bag with an air port is installed on the lower surface of the toilet seat and the toilet seat is closed, the air bag is pressed and compressed against the pedestal installed on the upper surface of the toilet bowl, Some of them absorb the impact force by discharging air and buffer the impact when the toilet seat is closed (see Non-Patent Document 2, for example).

  FIG. 7 shows a conventional toilet seat device described in Patent Document 2. As shown in FIG. As shown in FIG. 7, the airbag 2 is installed in the back lower surface of the toilet seat 1, and the base 3 is installed in the upper surface of the toilet bowl. When the toilet seat 1 is closed, the airbag 2 is compressed by the lower surface of the toilet seat 1 and the pedestal 3, and air is discharged from the air port 4 of the airbag 2.

  However, in the conventional configuration, a dedicated shock absorber is installed as a shock buffering means, and a dedicated space is required for installation, leading to an increase in the overall size of the toilet seat device and the use of dedicated parts. There was room for improvement in terms of increasing costs and increasing the number of man-hours required for assembly.

  The present invention has been made in view of the above-described conventional problems, and implements a toilet seat device capable of performing a smooth closing operation by implementing an impact buffering unit that suppresses an impact sound when the toilet seat is closed at a low cost. The purpose is to provide.

  In order to solve the above-described conventional problems, a toilet seat device of the present invention includes a main body placed and fixed on a toilet bowl, a seating position pivotally supported by the main body and having a seating surface substantially horizontal, and a seating And a toilet seat that is rotatable between an open position where the surface is substantially vertical, and a plurality of legs formed of a material having low resilience and compression deformation from the pivot shaft on the back surface of the toilet seat When the toilet seat is rotated from the open position to the seated position, the legs are arranged sequentially from the one arranged near the pivot shaft to the one arranged far away. It is formed at a height that makes contact with the upper surface of the toilet bowl at different timings.

  As a result, when the toilet seat is rotated by its own weight from the open position to the seated position, the leg closest to the pivot shaft first comes into contact with the upper surface of the toilet and the leg is compressed and deformed by the impact load to absorb the impact energy. Then, the rotational speed of the toilet seat is reduced. At this time, since the rotation speed of the leg closest to the pivot shaft is slow, a small impact sound is generated.

  When the nearest leg is compressed and deformed and the height is lowered, the next placed leg comes into contact with the upper surface of the toilet, and the rotational speed of the toilet seat is further reduced by compressing and deforming in the same manner as described above. At this time, the impact sound is suppressed because the rotation speed is already reduced by the contact of the leg closest to the pivot shaft.

  As described above, the legs arranged at a plurality of positions with different distances from the pivot shaft are sequentially brought into contact with the upper surface of the toilet, so that the impact sound generated by the contact between the toilet seat and the upper surface of the toilet is suppressed and the seat is smoothly seated. Can be stopped in position.

  As described above, it is possible to provide the shock absorbing means when the toilet seat is rotated by using the leg, which is an essential member of the toilet seat, in a small size and at a low cost.

  The toilet seat device of the present invention can provide a shock absorbing means for rotating the toilet seat in a small size and at low cost.

The first invention includes a main body placed and fixed on a toilet, a seating position pivotally supported by the main body and having a seating surface substantially horizontal, and an open position in which the seating surface is substantially vertical. A plurality of legs formed of a material having low resilience and compression deformability on the back surface of the toilet seat, and regulation means for regulating deformation of the legs The plurality of legs are arranged at a plurality of positions at different distances from the pivot shaft, and when the toilet seat is rotated from the open position to the seating position, the plurality of legs are arranged on the pivot shaft. From the position arranged near to the position arranged far away from each other, is formed at a height that makes contact with the upper surface of the toilet at different timings sequentially, and the restriction means is formed by compressing and deforming the leg, thereby restricting the restriction means. Abuts on the upper surface of the toilet, and the seating surface of the toilet seat is maintained substantially horizontal. It is those that.

  As a result, when the toilet seat is rotated by its own weight from the open position to the seated position, the leg closest to the pivot shaft first comes into contact with the upper surface of the toilet and the leg is compressed and deformed by the impact load to absorb the impact energy. Then, the rotational speed of the toilet seat is reduced. At this time, since the rotation speed of the leg closest to the pivot shaft is slow, a small impact sound is generated.

  When the nearest leg is compressed and deformed and the height is lowered, the next placed leg comes into contact with the upper surface of the toilet, and the rotational speed of the toilet seat is further reduced by compressing and deforming in the same manner as described above. At this time, the impact sound is suppressed because the rotation speed is already reduced by the contact of the leg closest to the pivot shaft.

  As described above, the legs arranged at a plurality of positions with different distances from the pivot shaft are sequentially brought into contact with the upper surface of the toilet, so that the impact sound generated by the contact between the toilet seat and the upper surface of the toilet is suppressed and the seat is smoothly seated. Can be stopped in position.

As described above, the impact buffering effect when the toilet seat is rotated can be realized in a small size and at a low cost by using the legs that are essential members of the toilet seat.

In addition, even if the user's weight is added to a leg having low resilience and compression deformation necessary for exerting an impact buffering effect, the regulating means comes into contact with the upper surface of the toilet bowl, so that the seating surface of the toilet seat Is maintained in a substantially horizontal position suitable for seating, so that stable seating can be maintained. Further, since the leg acts as a cushion from when the user's weight is added until it is regulated by the regulating means, the impact at the time of sitting can be alleviated and the user can sit comfortably.

In a second aspect of the invention, particularly in the first aspect of the invention, the restricting means is provided close to the leg.

  Thereby, since a leg and a control means are installed in the substantially the same place, arrangement | positioning of the projection part of a toilet seat back surface becomes simple, and maintenance, such as cleaning, can be performed easily.

In a third aspect of the invention, particularly in the second aspect of the invention, the restricting means is provided close to at least a leg farthest from the pivot shaft.

  As a result, the portion of the toilet seat close to the pivot shaft is maintained at a predetermined height by the pivot shaft, and the portion farther from the pivot shaft is maintained at the predetermined height by the regulating means. The seating surface can be maintained substantially horizontal.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 shows a perspective view of the appearance of the toilet seat device according to the present embodiment in a state where the toilet seat device is installed on the toilet, and FIG.

  A toilet lid 300 and a toilet seat 400 are rotatably attached to the main body 200 via a rotation shaft. In the state where the toilet lid 300 is opened as shown in FIG. 1, the toilet lid 300 stands so as to be positioned at the rearmost part of the toilet seat device 100. When the toilet lid 300 is closed, the upper surface of the toilet seat 400 is concealed.

  The toilet seat 400 has a seating position where the seating surface 411 is substantially horizontal so as to be suitable for a user to sit as shown in FIG. 1, and an open position where the seating surface 411 is substantially vertical as shown in FIG. It is configured so that it can be manually opened and closed. The toilet seat 400 has a built-in toilet seat heater (not shown) and heats the seating surface 411 of the toilet seat 400 to a comfortable temperature.

  A seating sensor 201 is installed at the front center of the main body 200. The seating sensor 201 is a reflective infrared sensor, and detects the presence of a user on the toilet seat 400 by detecting infrared light reflected from the human body.

  On the left side of the main body 200, a sleeve portion 210 is formed so as to protrude integrally with the main body 200, and a plurality of operation switches 211 and a display device 212 for operating each function of the toilet seat device 100 are installed on the upper surface of the sleeve portion 210. ing.

  Inside the main body 200, a cleaning means (not shown) for cleaning the local part of the human body, a drying device (not shown) for drying the local part after the cleaning, a deodorizing device (not shown) for deodorizing the odor during defecation, A control unit (not shown) for controlling these functions is installed, and the control unit controls each function based on the detection signal of the seating sensor 201 and the operation of the operation switch 211.

<2> Configuration of Toilet Seat FIG. 2 is a perspective view showing a state in which the toilet seat is opened to the open position, and FIG. FIG. 4 is a side view showing a state in which the toilet seat is closed at the seating position.

  As shown in FIGS. 1 and 2, the toilet seat 400 has a substantially elliptical annular shape, and pivot support portions 401 projecting from the rear end portion are formed on both sides of the toilet seat 400. The main body 200 is pivotally supported via 402.

  The toilet seat 400 is configured by combining an upper toilet seat casing 410 on the upper surface side and a lower toilet seat casing 420 on the lower surface side, and has a hollow shape. The upper toilet seat casing 410 has a seating surface 411 on which a user sits, and a toilet seat heater (not shown) is adhered to the back surface of the seating surface 411 so that the seating surface 411 can be heated to an appropriate temperature. it can. The seating surface 411 is formed as an inclined surface whose inner peripheral side is lowered over the entire circumference. Further, as shown in FIG. 1, in the state where the toilet seat 400 is stopped at the seating position, the central portion of the inclined surface serving as a reference for the seating surface 411 is substantially horizontal.

  As shown in FIG. 2, four legs 430 are bonded and fixed to the surface of the lower toilet seat casing 420 of the toilet seat 400 at symmetrical positions. The four legs 430 are installed at the rear two at a position about 10 cm from the pivot shaft 402 and at the two fronts at a position about 30 cm from the pivot shaft 402.

  The legs 430 are molded into a substantially elliptic cylinder shape by low foaming a resin material of a polymer of polystyrene and vinyl-polyisoprene. The resin material used in this embodiment has low resilience and compressive deformation. In particular, when a weight is dropped on a piece of material formed of an equivalent resin material, the acceleration that the weight receives during repulsion is about 1/5 that when chloroprene rubber is used, and the material compressed by pressure is the original. The time to return to the shape is about three times that of chloroprene rubber, and these characteristics provide a high level of low resilience to absorb impact.

  The height dimension H1 of the leg 430 formed in a substantially elliptical column shape is such that the toilet seat 400 is pivotally supported by the main body 200 via the pivot shaft 402, and the lower toilet seat casing 420 in which the leg 430 is installed. In a state where the surface and the upper surface of the toilet bowl 110 are parallel to each other, the dimension is larger than the gap dimension H2 between the surface of the lower toilet seat casing 420 and the upper surface of the toilet bowl 110, and is about 1.5 times in this embodiment.

  When the toilet seat 400 is rotated from the open position to the seating position by making the height dimension H1 of the leg 430 higher than the gap dimension H2, the leg 430 that is first installed at the rear is a short distance from the pivot shaft 402. Is configured to contact the upper surface of the toilet bowl 110, and then the leg 430 installed in the front having a long distance from the pivot shaft 402 contacts the upper surface of the toilet bowl 110 at different timings so that the toilet seat 400 stops on the upper surface of the toilet bowl 110. It can be.

  About the toilet seat apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When the toilet seat 400 is rotated by its own weight from the open position to the seated position as indicated by an arrow D in the figure, initially, the two rear legs 430 near the pivot shaft 402 are brought into contact with the upper surface of the toilet 110. The legs 430 are compressed and deformed by an impact load, absorb the impact energy, and reduce the rotational speed of the toilet seat 400. At this time, the distance between the rear leg 430 and the pivot leg 402 is about 1/3 with respect to the front leg 430, so that the speed at which the rear leg 430 collides with the upper surface of the toilet 110 is also about 1/3, and is generated at the time of contact. Impact noise can be suppressed.

  When the rear leg 430 is compressed and deformed and the height is lowered, the leg 430 arranged in front is brought into contact with the upper surface of the toilet 110, and the rotational speed of the toilet seat 400 is further reduced by compressing and deforming in the same manner as described above. To do. At this time, the impact sound generated is suppressed because the rotational speed has already been reduced by the contact of the rear leg 430 close to the pivot shaft 402.

  As described above, in the present embodiment, the toilet seat and the toilet upper surface come into contact with each other by the legs 430 arranged at a plurality of positions at different distances from the pivot shaft 402 sequentially contacting the upper surface of the toilet bowl. The generated impact sound is suppressed and the seating position can be smoothly stopped.

  Further, in the present embodiment, the impact buffering effect at the time of toilet seat rotation is established using the legs that are essential members of the toilet seat, thereby realizing downsizing and cost reduction.

  In the present embodiment, two legs are installed at two different distances from the pivot axis, but the present invention is not limited to this, and the legs may be arranged at three or more different distances. Similar effects can be obtained. Further, the arrangement of the legs is not limited to the left and right target positions.

  Further, in the present embodiment, the shape and height of the legs are all the same, but this is not restrictive, and different shapes and heights may be used. In particular, the cushioning effect can be enhanced by increasing the height of the legs installed near the pivot shaft.

(Embodiment 2)
FIG. 5A is a side view showing a state in which the toilet seat according to the second embodiment is being rotated from the open position to the seating position, and FIG. 5B is a cross-sectional view showing details of the portion A shown in FIG. 6 (a) is a side view of a state in which a user is seated on the toilet seat in the second embodiment, and (b) is a cross-sectional view showing details of a portion B shown in (a).

  The difference between the present embodiment and the first embodiment is that the leg installed behind the toilet seat 400 uses the same leg 430 as that of the first embodiment, but is disposed in the front with a long distance from the pivot shaft 402. In addition, a restricting portion 450 serving as a restricting means for restricting the deformation of the leg 440 is provided so as to cover the periphery of the leg 440, and the rest of the toilet seat device has the same configuration as that of the first embodiment and is described in detail. Description is omitted.

  As shown in FIG. 5 (b), the leg 440 installed in the front in the present embodiment has a two-stage columnar shape with a thick original part and a narrower tip. It is molded using the same resin material. The height of the leg 440 is the same height as the height dimension H1 of the leg 430 disposed rearward.

A cylindrical regulating portion 450 is integrally formed with the lower toilet seat casing 420 at the place where the leg 440 is installed. The inner diameter of the restricting portion 450 is formed to be slightly larger than the original portion of the leg 440, and positioning when the leg 440 is bonded and fixed inside is easy. Further, the height of the restricting portion 450 is the same as the surface of the lower toilet seat casing 420 described in the first embodiment and the toilet 1.
10 is the same dimension as the gap dimension H2 between the surface of the lower toilet seat casing 420 and the upper surface of the toilet bowl 110 in a state where the upper surface of 10 is parallel.

  As shown in FIG. 5B, in the state where the leg 440 is installed inside the restricting portion 450, a gap is formed between the thin portion of the leg 440 and the inner surface of the restricting portion 450. When the leg 440 is compressed, a deformation space 451 for accommodating a deformation that expands in the lateral direction is formed. When the leg 440 is compressed and deformed by the load, the restricting portion 450 comes into contact with the upper surface of the toilet 110 as shown in FIG. 6A and further compressive deformation is restricted, and as shown in FIG. 6B. The deformation space 451 is almost filled with the legs 440. In this state, since the height of the restricting portion 450 is the gap dimension H2, the seating surface 411 of the toilet seat 400 is maintained substantially horizontal.

  About the toilet seat apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Similarly to the first embodiment, when the toilet seat 400 is rotated by its own weight from the open position to the seated position, the two legs 430 at the back first contact the upper surface of the toilet 110 and the legs 430 are subjected to an impact load. It compresses and deforms, absorbs impact energy, and decelerates the rotational speed of the toilet seat 400. Next, the leg 440 disposed in front contacts the upper surface of the toilet 110 and compresses and deforms, whereby the rotational speed of the toilet seat 400 is further reduced and stopped.

  In the state where the toilet seat 400 is stopped on the toilet 110, the front of the toilet seat 400 is slightly raised by the repulsive force of the legs 430 and 440. When the user sits on the toilet seat 400 in this state, The leg 430 and the leg 440 are compressed and deformed, the restricting portion 450 abuts on the upper surface of the toilet 110, and the toilet seat 400 is maintained at a predetermined height. At this time, the height of the front of the toilet seat 400 is maintained by the restriction portion 450, and the rear of the toilet seat 400 is maintained at a predetermined height by the rotation support portion 401 and the pivot shaft 402. It can be maintained approximately horizontal that is optimal for seating.

  As described above, in the present embodiment, even when the user's weight is added to a leg having low resilience and compression deformability necessary for exerting an impact buffering effect, the deformation of the leg is within a predetermined range. Therefore, the seating surface of the toilet seat is maintained substantially horizontal suitable for seating, so that stable seating can be maintained. In addition, since the leg acts as a cushion from when the user's weight is added until it is regulated by the regulating unit, the impact at the time of sitting can be alleviated and the user can sit comfortably. Furthermore, since the leg and the restricting portion are installed at substantially the same place, the arrangement of the protrusion on the back surface of the toilet seat is simplified, and maintenance such as cleaning can be easily performed.

  In addition, since the restricting portion is provided at least close to the leg farthest from the pivot shaft, the portion close to the pivot shaft of the toilet seat is maintained at a predetermined height by the pivot shaft, and is a portion far from the pivot shaft. Is maintained at a predetermined height by the restricting portion, so that the seating surface of the toilet seat can be maintained substantially horizontal with a few restricting portions.

  In addition, although this Embodiment provided the control part so that the leg far from a pivot could be covered, it is not restricted to this, You may provide a control part in all the legs.

  In this embodiment, the restricting portion is provided so as to cover the entire circumference of the leg. However, the present invention is not limited to this. It is possible to exert the effect of maintaining the level of the toilet seat even with a configuration provided in a similar manner.

As described above, since the toilet seat device according to the present invention can cushion the impact at the time of rotation, the toilet seat device can also be applied to various devices having a rotation function.
