Description

本発明は上下２分割された上部材と下部材とで構成される便座に関する。 The present invention relates to a toilet seat composed of an upper member and a lower member which are divided into upper and lower parts.

従来の便座としては、例えば特許文献１に示すように、便座を、着座者側となる上面を構成する上部材と、反対側の下面を構成する下部材との二部材で構成したものがある。 As a conventional toilet seat, for example, as shown in Patent Document 1, there is a toilet seat configured by two members, an upper member that constitutes an upper surface on the seated side and a lower member that constitutes a lower surface on the opposite side. .

この種の便座は、着座者からの荷重を下部材における上部材との接合部である内周縁部及び外周縁部のみで受け、これを脚部を介して便器側に伝えるものである。このため便座に応力集中が生じて便座が変形したり破損したりする恐れがある。
特開２００６−４９１号公報 This type of toilet seat receives a load from a seated person only at the inner peripheral edge and the outer peripheral edge, which are the joints of the lower member with the upper member, and transmits this to the toilet side via the legs. For this reason, stress concentration occurs in the toilet seat, and the toilet seat may be deformed or damaged.

Further, the upper end of each support portion 19 is not in contact with the upper member 7 and is disposed below the upper surface portion 9 through a slight gap, and the upper surface portion 9 of the upper member 7 bends downward due to the load of the seated person. At this time, the upper surface portion 9 of the upper member 7 may be supported by the upper end of each support portion 19.

また、図４等に示すように、下部材８の下面部１３の前部両側には、使用者が便座１の着座部４上に着座したことを検出するための手段として着座検知装置２２を設けている。図８に示すように、各着座検知装置２２は、マイクロスイッチからなるスイッチ２３と、着座時にスイッチ２３を切替操作する操作部材２４を備えている。 Further, as shown in FIG. 4 and the like, a seating detection device 22 is provided on both sides of the front portion of the lower surface portion 13 of the lower member 8 as means for detecting that the user is seated on the seating portion 4 of the toilet seat 1. Provided. As shown in FIG. 8, each seating detection device 22 includes a switch 23 composed of a microswitch and an operation member 24 that switches the switch 23 when seated.

スイッチ２３及び操作部材２４は共に下部材８の下面部１３に取り付けられる。操作部材２４は上方に開口する略凹状のゴム材からなり、操作部材２４の底部中央には上方に向けてスイッチ操作部２５を突出している。 Both the switch 23 and the operation member 24 are attached to the lower surface portion 13 of the lower member 8. The operation member 24 is made of a substantially concave rubber material that opens upward, and a switch operation portion 25 protrudes upward at the center of the bottom of the operation member 24.

上記便座１を使用するときには、便座１を取付部２７に対して回動し、便座１の下面に設けた各脚部１４の底部と各操作部材２４の底部２８を便器本体２の上面に載置する。つまり各脚部１４のみならず各操作部材２４も便座１の脚として機能するものであり、便座１は後部両側の脚部１４と前部両側の操作部材２４の４点で支持される。 When the toilet seat 1 is used, the toilet seat 1 is rotated with respect to the mounting portion 27, and the bottom portions of the leg portions 14 and the bottom portions 28 of the operation members 24 provided on the lower surface of the toilet seat 1 are placed on the upper surface of the toilet body 2. Put. That is, not only each leg part 14 but each operation member 24 functions as a leg of toilet seat 1, and toilet seat 1 is supported by four points of leg part 14 of the both sides of the back, and operation member 24 of both sides of the front part.

上記便器本体２上に載置した便座１に使用者が着座すると、この着座者の荷重は上部材７から下部材８に伝わり、下部材８の各脚部１４及び各操作部材２４を介して便器本体２に伝わる。 When a user sits on the toilet seat 1 placed on the toilet main body 2, the load of the seated person is transmitted from the upper member 7 to the lower member 8, and the legs 14 and the operation members 24 of the lower member 8 are passed through. It is transmitted to the toilet body 2.

上記着座者からの荷重により各着座検知装置２２の操作部材２４が弾性変形して便座１の前側は若干下方に移動する。このとき、各操作部材２４のスイッチ操作部２５によりスイッチ２３が切替えられて便座１に使用者が着座したことが検知される。この検知結果は加熱手段や、便器本体２に設けられる脱臭装置や洗浄装置等の各種装置の動作制御に用いられる。 The operation member 24 of each seating detection device 22 is elastically deformed by the load from the seated person, and the front side of the toilet seat 1 moves slightly downward. At this time, it is detected that the switch 23 is switched by the switch operation unit 25 of each operation member 24 and the user is seated on the toilet seat 1. This detection result is used for operation control of various devices such as a heating means and a deodorizing device or a cleaning device provided in the toilet body 2.

ここで、上記上部材７の上面部９に加わる着座者の荷重は、下部材８における上部材７との接合部である内外の周縁部と、各支持部１９の上端に伝わる。このため上部材７から下部材８に加わる荷重を分散することができ、薄肉の便座１の変形や破損を防止できる。 Here, the load of the seated person applied to the upper surface portion 9 of the upper member 7 is transmitted to the inner and outer peripheral edge portions of the lower member 8 that are joined to the upper member 7 and the upper ends of the support portions 19. For this reason, the load applied from the upper member 7 to the lower member 8 can be dispersed, and deformation and breakage of the thin toilet seat 1 can be prevented.

また、各支持部１９に加わった荷重は直下に位置する便器本体２上に載置された脚部１４に直接伝わり、上部材７の外周壁部１０や内周壁部１１、下部材８の下面部１３等には大きな荷重が加わらないようになっている。従ってより一層便座１の変形や破損を防止できる。 Further, the load applied to each support portion 19 is directly transmitted to the leg portion 14 placed on the toilet main body 2 located immediately below, and the lower surface of the outer peripheral wall portion 10, the inner peripheral wall portion 11, and the lower member 8 of the upper member 7. A large load is not applied to the portion 13 or the like. Therefore, the toilet seat 1 can be further prevented from being deformed or damaged.

また、脚部１４の底部から上部材７を支持するための支持部を突出することが考えられるが、このように合成樹脂製品である下部材８の脚部１４に支持部を形成した場合、脚部１４の薄肉の底部の外面において「ヒケ」が生じ、このヒケが便座１を起立させたときに外観上目立って見栄えを悪くする恐れがある。 In addition, it is conceivable to project a support part for supporting the upper member 7 from the bottom part of the leg part 14, but when the support part is formed on the leg part 14 of the lower member 8 which is a synthetic resin product in this way, A “sink” occurs on the outer surface of the bottom of the thin wall of the leg 14, and this sink may stand out from the appearance when the toilet seat 1 is erected.

しかし、本実施形態では上記支持部１９を脚部１４の底部ではなく下部材８の下面部１３と脚部１４の壁部とでなす支持部１９に対して厚肉となったコーナー部１８の内面に形成してあるので、上記ヒケの発生を抑えることができる。また仮にヒケが生じたとしてもこのヒケは目立ち難い脚部１４の根元部に位置するコーナー部１８の外面に生じるものであり、外観が阻害されることもない。 However, in the present embodiment, the corner portion 18 is thicker than the supporting portion 19 formed by the lower surface portion 13 of the lower member 8 and the wall portion of the leg portion 14 instead of the bottom portion of the leg portion 14. Since it is formed on the inner surface, the occurrence of sink marks can be suppressed. Further, even if sink marks are generated, the sink marks are generated on the outer surface of the corner portion 18 located at the base portion of the leg portion 14 which is not conspicuous, and the appearance is not hindered.
