Description

本発明は、便座装置とその製造方法に関するものであり、特に暖房機能を有した便座装置に好適である。   The present invention relates to a toilet seat device and a manufacturing method thereof, and is particularly suitable for a toilet seat device having a heating function.

樹脂製の便座装置（以下樹脂便座ともいう）は、従来の陶器製のものと比べ軽くて丈夫であり、意匠性にも優れることから、益々その需要が高まっている。例えば、特許文献１には、座面部材と裏面部材に分割された部品を組み合わせた便座装置が開示されている。   Resin toilet seat devices (hereinafter also referred to as resin toilet seats) are lighter and stronger than conventional ceramic toilet seats, and are excellent in design. For example, Patent Document 1 discloses a toilet seat device in which parts divided into a seat member and a back member are combined.

特開２００１−２４５８２５号公報JP 2001-245825 A

ところで、従来の樹脂便座では、座面部材若しくは裏面部材に補強部材が設けられている。即ち、この樹脂便座は、座面部材の弾性と補強部材の剛性によって、使用者の着座荷重を支えている。しかしながら、この構成は、成形時に座面部材や裏面部材の表面にヒケが発生することを防止する為に、補強部材の厚みや補強部材の位置に制限が存在している。そのため、座面部材の厚さを薄くすると、使用者が着座するにあたって、十分な強度が得られない。また、通常の厚さの座面部材を用いても、位置によって強度の低いところと高いところが生じる恐れがある。即ち、使用者の体重や着座姿勢によって荷重に偏りが生じた状態で使用し続けると、便座に亀裂等が入る恐れがあった。   By the way, in the conventional resin toilet seat, the reinforcement member is provided in the seat surface member or the back surface member. That is, the resin toilet seat supports the seating load of the user by the elasticity of the seat member and the rigidity of the reinforcing member. However, this configuration has limitations on the thickness of the reinforcing member and the position of the reinforcing member in order to prevent the occurrence of sink marks on the surface of the seat member and the back member during molding. Therefore, if the thickness of the seat member is reduced, sufficient strength cannot be obtained when the user is seated. Further, even if a seat member having a normal thickness is used, there is a possibility that a low strength portion and a high strength portion may be generated depending on the position. That is, if the user continues to use the load with a bias caused by the user's weight or sitting posture, the toilet seat may be cracked.

そこで、本発明では、従来技術の問題に鑑み、剛性の高い便座装置を提供することを課題とする。   In view of the problems of the prior art, an object of the present invention is to provide a toilet seat device with high rigidity.

上記課題を解決するため、請求項１に記載の発明は、座面を形成する座面部材と、便器に載置する裏面部材と、座面部材と裏面部材とに囲まれた空間に設置されたリブ部材からなる便座装置において、リブ部材は、座面部材と裏面部材を天地方向に支持する本体部と、本体部を介して互いに離反方向に突出した内側リブ片と外側リブ片を有し、内側リブ片と外側リブ片は、座面部材又は裏面部材を固着支持する便座装置であって、座面部材は、座板部とその両端部から下方向に向かって折れ曲がった内側座板支持部及び外側座板支持部とから形成され、裏面部材は、裏板部とその両端部から上方向に向かって折れ曲がった内側裏板支持部及び外側裏板支持部とから形成されており、リブ部材の本体部は、その高さ寸法が裏面部材の裏板部の上面から座面部材の座板部の下面までの長さに等しくなるように形成され、この本体部の内側側面及び外側側面の高さ範囲の中程から内側リブ片及び外側リブ片が各々張り出していて、同本体部の上端部分で座面部材の座板部の中程部分が支持され、内側リブ片及び外側リブ片の先端部分で座面部材の内側座板支持部及び外側座板支持部の下端部分と裏面部材の内側裏板支持部及び外側裏板支持部の上端部分とが固着一体化されていることを特徴とする便座装置である。 In order to solve the above problems, the invention according to claim 1 is installed in a space surrounded by a seat member that forms a seat surface, a back member that is placed on a toilet, and the seat member and the back member. In the toilet seat device comprising the rib member, the rib member has a main body portion that supports the seat surface member and the back surface member in the vertical direction, and an inner rib piece and an outer rib piece that protrude in a direction away from each other via the main body portion. The inner rib piece and the outer rib piece are toilet seat devices that firmly support and support the seat member or the back member, and the seat member supports the inner seat plate bent downward from the seat plate portion and both ends thereof. The back member is formed of a back plate portion, an inner back plate support portion and an outer back plate support portion that are bent upward from both ends thereof, and a rib. The main body of the member has a height dimension above the back plate of the back member. To the lower surface of the seat plate portion of the seat member, and the inner rib piece and the outer rib piece respectively project from the middle of the height range of the inner side surface and the outer side surface of the main body portion. The middle portion of the seat plate portion of the seat member is supported by the upper end portion of the main body portion, and the inner seat plate support portion and the outer seat plate support portion of the seat member are supported by the tip portions of the inner rib piece and the outer rib piece. The toilet seat device is characterized in that the lower end portion of the back surface and the inner back plate support portion of the back member and the upper end portion of the outer back plate support portion are fixedly integrated .

かかる構成によれば、座面部材と裏面部材とリブ部材の３部材で構成されているため、使用用途に応じた座面部材と裏面部材とリブ部材の各々の設計が可能である。即ち、リブ部材は、座面部材と裏面部材とに囲まれた空間の範囲内で、リブ部材の内側リブ片と外側リブ片の、厚みや本数などを自由に設計可能である。また、座面部材と裏面部材を天地方向に支持する本体部と、本体部を介して互いに離反方向に突出した内側リブ片と外側リブ片を有するため、位置による強度の偏りが生じにくい。即ち、例え座面部材の偏った位置に使用者の着座荷重が加わったとしても、高い剛性を維持することができる。言い換えると、リブ部材の存在により、剛性を向上させることができるため、座面部材の厚みを薄く設計することもできる。即ち、例えば本発明を暖房便座に採用した場合には、座面部材の厚みを薄く設計することもできるため、便座に内蔵されたヒーターからの熱を効率良く伝えることができる。   According to this structure, since it is comprised by three members, a seat surface member, a back surface member, and a rib member, each design of the seat surface member, a back surface member, and a rib member according to a use application is possible. That is, the rib member can be freely designed with respect to the thickness and number of inner rib pieces and outer rib pieces of the rib member within a space surrounded by the seat member and the back member. Moreover, since it has the main-body part which supports a seat surface member and a back surface member in the top-and-bottom direction, and the inner side rib piece and outer side rib piece which protruded in the mutually separated direction via the main-body part, the intensity | strength bias | deviation by a position hardly arises. That is, even if a user's seating load is applied to the position where the seating surface member is biased, high rigidity can be maintained. In other words, since the rigidity can be improved by the presence of the rib member, the thickness of the seat member can be designed to be thin. That is, for example, when the present invention is applied to a heated toilet seat, the seat member can be designed to be thin, so that the heat from the heater built in the toilet seat can be transmitted efficiently.

請求項２に記載の発明は、座面を形成する座面部材と、便器に載置する裏面部材と、座面部材と裏面部材とに囲まれた空間に設置されたリブ部材からなる便座装置において、リブ部材は、座面部材と裏面部材を天地方向に支持する本体部と、本体部を介して互いに離反方向に突出した内側リブ片と外側リブ片を有し、内側リブ片と外側リブ片は、座面部材又は裏面部材を固着支持することを特徴とする便座装置の製造方法であって、内側リブ片と外側リブ片は、摩擦発熱によって座面部材及び裏面部材と一体化することを特徴とする便座装置の製造方法である。 According to a second aspect of the present invention, there is provided a toilet seat device comprising a seat member that forms a seat surface, a back member that is placed on the toilet, and a rib member that is installed in a space surrounded by the seat member and the back member. The rib member includes a main body portion that supports the seat surface member and the back surface member in the vertical direction, and an inner rib piece and an outer rib piece that protrude in a direction away from each other via the main body portion, and the inner rib piece and the outer rib. The piece is a method for manufacturing a toilet seat device, wherein the seat member or the back member is fixedly supported, and the inner rib piece and the outer rib piece are integrated with the seat member and the back member by frictional heat generation. This is a method for manufacturing a toilet seat device.

ここで、摩擦発熱とは、材料の摩擦熱を利用して加熱することを表す。即ち、摩擦発熱によって一体化するとは、振動溶着やスピン溶着、超音波溶着などを含む概念である。   Here, the frictional heat generation means heating using the frictional heat of the material. That is, integrating by frictional heat generation is a concept including vibration welding, spin welding, ultrasonic welding, and the like.

かかる方法によれば、内側リブ片と外側リブ片は、摩擦発熱によって座面部材及び裏面部材と一体化するため、不可分一体に接着可能である。言い換えると、破壊や変形等を行わない限り、分離することがなく、剛性がより向上する。   According to such a method, the inner rib piece and the outer rib piece are integrated with the seat member and the back member by frictional heat generation, and therefore can be inseparably integrated. In other words, unless it is destroyed or deformed, it is not separated and the rigidity is further improved.

本発明の便座装置では、座面部材と裏面部材とリブ部材の３部材で構成されているため、使用用途に応じた座面部材と裏面部材とリブ部材の各々の設計が可能である。即ち、リブ部材は、座面部材と裏面部材とに囲まれた空間の範囲内で、リブ部材の内側リブ片と外側リブ片の、厚みや本数などを自由に設計可能である。また、座面部材と裏面部材を天地方向に支持する本体部と、本体部を介して互いに離反方向に突出した内側リブ片と外側リブ片を有するため、位置による強度の偏りが生じにくい。即ち、例え座面部材の偏った位置に使用者の着座荷重が加わったとしても、高い剛性を維持することができる。言い換えると、リブ部材の存在により、剛性を向上させることができるため、座面部材の厚みを薄く設計することもできる。即ち、例えば本発明を暖房便座に採用した場合には、座面部材の厚みを薄く設計することもできるため、便座に内蔵されたヒーターからの熱を効率良く伝えることができる。   In the toilet seat device of the present invention, since the seat member is composed of the seat member, the back member, and the rib member, each of the seat member, the back member, and the rib member can be designed according to the intended use. That is, the rib member can be freely designed with respect to the thickness and number of inner rib pieces and outer rib pieces of the rib member within a space surrounded by the seat member and the back member. Moreover, since it has the main-body part which supports a seat surface member and a back surface member in the top-and-bottom direction, and the inner side rib piece and outer side rib piece which protruded in the mutually separated direction via the main-body part, the intensity | strength bias | deviation by a position hardly arises. That is, even if a user's seating load is applied to the position where the seating surface member is biased, high rigidity can be maintained. In other words, since the rigidity can be improved by the presence of the rib member, the thickness of the seat member can be designed to be thin. That is, for example, when the present invention is applied to a heated toilet seat, the seat member can be designed to be thin, so that the heat from the heater built in the toilet seat can be transmitted efficiently.
