Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a toilet according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the main part of the lid fixing structure according to the first embodiment of the present invention, and FIG. 3 is a view of the fixing member and the latch receiving portion viewed from the right side in FIG. FIG. 4 is an enlarged perspective view of the fixing member.
In FIG. 1, 1 is a toilet body, and 10 is a tank. A lid 12 is placed on the top of the tank 10 and fixed to the tank 10 by a fixing structure (not shown).
図２、図３に示すように、本発明の第１実施例の蓋の固定構造は、側面に貫通穴１４が形成されたタンク１０と、その貫通穴１４に回動自在に軸支されタンク１０の内側に向かって延出するボルト１６と、ボルト１６に螺設され先端がフック状に形成された掛止部１８と、掛止部１８を掛止する掛止受部２０が内側に設けられた蓋１２と、を備えている。ここで、タンク１０の側面とは、タンク１０の底面から上方に延びて壁状に形成された部分である。図２においてはタンク１０を正面から見たときの左側の側面を示しているが、右側の側面に対しても同様の固定構造にて固定されている。 As shown in FIGS. 2 and 3, the lid fixing structure according to the first embodiment of the present invention includes a tank 10 having a through hole 14 formed in a side surface, and a tank pivotally supported by the through hole 14. 10, a bolt 16 extending inward of the bolt 10, a hooking portion 18 screwed on the bolt 16 and having a hook-shaped tip, and a hook receiving portion 20 for hooking the hooking portion 18. And a lid 12 is provided. Here, the side surface of the tank 10 is a portion that extends upward from the bottom surface of the tank 10 and is formed in a wall shape. Although FIG. 2 shows the left side surface when the tank 10 is viewed from the front, it is fixed to the right side surface with the same fixing structure.
貫通穴１４の内面には、筒状のボルトガイド２２が設けられ、タンク１０の内側よりナット２４で締め付けられてタンク１０の側面に固定されている。このボルトガイド２２は、例えばタンク１０が陶器で形成され、貫通穴１４の大きさにバラつきが生じる場合であっても、ボルト１６を安定して略水平に軸支するために設けられている。 A cylindrical bolt guide 22 is provided on the inner surface of the through hole 14 and is fastened by a nut 24 from the inside of the tank 10 to be fixed to the side surface of the tank 10. The bolt guide 22 is provided to stably support the bolt 16 substantially horizontally even when the tank 10 is formed of ceramics and the size of the through hole 14 varies.
ボルト１６は、六角穴が形成された頭部１６ａとねじ山が形成されたおねじ部１６ｂとを有する。ボルト１６の頭部１６ａは、タンク１０の外部に配置され、おねじ部１６ｂは貫通穴１４を介してタンク１０の内部に略水平に延出させて配置される。なお、本実施形態において、おねじ部１６ｂのねじ山は、おねじ部１６ｂの先端側の一部に形成されているが、おねじ部１６ｂ全体に亘って形成されていても良い。 The bolt 16 has a head portion 16a having a hexagonal hole and a male screw portion 16b having a thread. The head portion 16 a of the bolt 16 is disposed outside the tank 10, and the external thread portion 16 b is disposed so as to extend substantially horizontally inside the tank 10 through the through hole 14. In the present embodiment, the thread of the external thread 16b is formed on a part of the distal end side of the external thread 16b, but may be formed over the entire external thread 16b.
掛止部１８は、ボルト１６のおねじ部１６ｂに螺合されるめねじ部１８ｂと、めねじ部より上方に延びて先端がフック形状に形成されたフック部１８ａとを備えている。このように掛止部１８のめねじ部１８ｂをボルト１６のおねじ部１６ｂに螺合させることで、ボルト１６の回転によって、掛止部１８がボルト１６の軸方向に進退可能に構成される。
以下に、第１実施例の蓋の固定構造について、その取り付け手順を示す。
まず、掛止部１８が図２のＡの位置にある状態でタンク１０の上部に蓋１２を載置する。そして、タンク１０の外部に露出するボルト１６の頭部１６ａを工具等で一方向に回すことで、おねじ部１６ｂも回転し、おねじ部１６ｂに螺合された掛止部１８がボルト１６のおねじ部１６ｂに沿ってタンク１０の側面に近づく方向（図２のＡからＢに向かう方向）に移動する。そして、掛止部１８が図２のＢの位置まで達すると、掛止部１８の先端に形成されたフック部１８ａが掛止受部２０に掛止され、蓋１２がタンク１０に固定された状態となる。
The latching portion 18 includes a female screw portion 18b that is screwed into the male screw portion 16b of the bolt 16, and a hook portion 18a that extends upward from the female screw portion and has a tip formed in a hook shape. Thus, by engaging the female thread portion 18b of the latching portion 18 with the male thread portion 16b of the bolt 16, the latching portion 18 is configured to be able to advance and retract in the axial direction of the bolt 16 by the rotation of the bolt 16. .
The attachment procedure for the lid fixing structure of the first embodiment will be described below.
First, the lid 12 is placed on the upper portion of the tank 10 with the latching portion 18 at the position A in FIG. Then, by turning the head 16a of the bolt 16 exposed to the outside of the tank 10 in one direction with a tool or the like, the male screw portion 16b also rotates, and the latching portion 18 screwed into the male screw portion 16b is connected to the bolt 16. It moves along the male screw portion 16b in a direction approaching the side surface of the tank 10 (a direction from A to B in FIG. 2). When the latching portion 18 reaches the position B in FIG. 2, the hook portion 18 a formed at the tip of the latching portion 18 is latched by the latch receiving portion 20, and the lid 12 is fixed to the tank 10. It becomes a state.
図２に示すような第１実施例においては、タンク１０内部にインナータンク３０や結露防止カバー３２などが設けられているため、ボルト１６の下方にはスペースがあまりない。したがって、掛止部１８は、ボルト１６のおねじ部１６ｂに螺合されためねじ部１８ｂから上方に延びた形状になるため、掛止部１８の重心がボルト１６より高い位置になる。よって、掛止部１８が、ボルトのおねじ部１６ｂを中心に回転しやすく、掛止部１８のフック部１８ａが、ボルト１６より下方の位置まで移動してしまう可能性がある。 In the first embodiment as shown in FIG. 2, the inner tank 30 and the dew condensation prevention cover 32 are provided inside the tank 10, so that there is not much space below the bolt 16. Accordingly, since the latching portion 18 is screwed into the male threaded portion 16b of the bolt 16 and has a shape extending upward from the threaded portion 18b, the center of gravity of the latching portion 18 is higher than the bolt 16. Therefore, the latching portion 18 can easily rotate around the male threaded portion 16 b of the bolt, and the hook portion 18 a of the latching portion 18 may move to a position below the bolt 16.
そこで掛止部１８の回転を防止するために、ガイド部材２６（回転防止手段）が設けられている。ガイド部材２６は、図４に示すように、掛止部１８のフック部１８ａを挟みおねじ部１６ｂと平行に設けられた板状のガイド部２６ａと、ガイド部２６ａと連設されナット２４によってタンク１０の側面に固定される板状のガイド固定部２６ｂと、から構成されている。ガイド部２６ａが、掛止部１８のフック部１８ａの回転方向に対して両側から挟むように配置されているため、仮にフック部１８ａがボルト１６のおねじ部１６ｂを中心に回転しようとしても、ガイド部２６ａに突き当たり回転が防止される。したがって、掛止部１８は回転することなく、ボルト１６の軸方向に沿って（ガイド部２６ａに沿って）移動することが可能となる。 Therefore, a guide member 26 (rotation preventing means) is provided in order to prevent rotation of the latching portion 18. As shown in FIG. 4, the guide member 26 includes a plate-like guide portion 26 a provided in parallel with the external thread portion 16 b with the hook portion 18 a of the latching portion 18 interposed therebetween, and a guide portion 26 a provided continuously with a nut 24. And a plate-like guide fixing portion 26 b fixed to the side surface of the tank 10. Since the guide part 26a is arranged so as to be sandwiched from both sides with respect to the rotation direction of the hook part 18a of the hook part 18, even if the hook part 18a tries to rotate around the threaded part 16b of the bolt 16, Abutting against the guide portion 26a prevents rotation. Therefore, the latching portion 18 can move along the axial direction of the bolt 16 (along the guide portion 26a) without rotating.
次に、本発明の第２実施例の蓋の固定構造について説明する。図５は本発明の第２実施例の蓋の固定構造の要部断面図である。なお、ここでは上述の第１実施例と異なる点を中心に説明する。 Next, the lid fixing structure of the second embodiment of the present invention will be described. FIG. 5 is a cross-sectional view of the principal part of the lid fixing structure of the second embodiment of the present invention. Here, the description will focus on the differences from the first embodiment described above.
第２実施例の蓋の固定構造としては、掛止部１８において、めねじ部１８ｂより下方に延びる延出部１８ｃ（回転防止手段）が設けられている。これにより、掛止部１８の重心がボルト１６より低い位置になる。したがって、ボルト１６を回転したとしても、掛止部１８は回転することなく、ボルト１６の軸方向に沿って進退させることが可能となる。したがって、第１実施例のようにガイド部材２６を別途設けなくても、掛止部１８の回転を防止できる。したがって、第１実施例よりも部品点数が少なく、コストを低く抑えた蓋の固定構造を提供できる。なお、第２実施例の蓋の固定構造における取り付け手順は第１実施例と同じであるため、省略する。 As a lid fixing structure according to the second embodiment, an extending portion 18c (rotation preventing means) extending downward from the female screw portion 18b is provided in the latching portion 18. As a result, the center of gravity of the latching portion 18 is lower than the bolt 16. Therefore, even if the bolt 16 is rotated, the hooking portion 18 can be advanced and retracted along the axial direction of the bolt 16 without rotating. Therefore, the rotation of the latching portion 18 can be prevented without providing the guide member 26 separately as in the first embodiment. Therefore, it is possible to provide a lid fixing structure that has a smaller number of parts than the first embodiment and that is low in cost. In addition, since the attachment procedure in the fixing structure of the lid of the second embodiment is the same as that of the first embodiment, the description thereof is omitted.
次に、本発明の第３実施例の蓋の固定構造について説明する。図６は本発明の第３実施例の蓋の固定構造の要部断面図である。なお、ここでも上述の第１実施例と異なる点を中心に説明する。 Next, the lid fixing structure of the third embodiment of the present invention will be described. FIG. 6 is a cross-sectional view of the main part of the lid fixing structure of the third embodiment of the present invention. Note that here, the description will focus on differences from the first embodiment.
第３実施例の蓋の固定構造としては、掛止部１８の先端に折り返し部１８ｄが設けられており、さらにボルト１６のおねじ部１６ｂには掛止部１８のめねじ部１８ｂに当接するように回転防止ナット４０が設けられている。 As the lid fixing structure of the third embodiment, a folded portion 18d is provided at the tip of the latching portion 18, and the male threaded portion 16b of the bolt 16 contacts the female threaded portion 18b of the latching portion 18. Thus, a rotation prevention nut 40 is provided.
第３実施例における蓋の固定構造の取り付け手順としては、以下に示す通りである。
まず、ボルト１６のおねじ部１６ｂに、掛止部１８のめねじ部１８ｂを螺合させる。次いで、おねじ部１６ｂに回転防止ナット４０を螺合させ、掛止部１８のめねじ部１８ｂに当接する位置まで移動させる。このとき、掛止部１８を図６のＡの位置に配置させる。そして、タンク１０の上部に蓋１２を載置し、タンク１０の外部よりボルト１６の頭部１６ａを外側に引き出すことで、掛止部１８の折り返し部１８ｄを蓋１２の内部に形成された掛止受部２０に掛止させる。（このときの掛止部１８は図６のＢの位置になる。）その後、ボルト１６の頭部１６ａの引き出した分を、タンク１０に対してねじ込むことで取り付けが完了する。
The procedure for attaching the lid fixing structure in the third embodiment is as follows.
First, the female screw portion 18b of the latching portion 18 is screwed into the male screw portion 16b of the bolt 16. Next, the rotation prevention nut 40 is screwed into the male screw portion 16 b and moved to a position where it contacts the female screw portion 18 b of the latching portion 18. At this time, the latching portion 18 is disposed at the position A in FIG. Then, the lid 12 is placed on the upper part of the tank 10, and the head portion 16 a of the bolt 16 is pulled out from the outside of the tank 10, so that the folded portion 18 d of the latching portion 18 is formed inside the lid 12. Hang on the stopper 20. (At this time, the latching portion 18 is in the position shown in FIG. 6B.) After that, the portion of the bolt 16 that has been pulled out of the head 16a is screwed into the tank 10 to complete the mounting.
以上、本実施形態を詳述したが、これはあくまで一例である。例えば、本実施形態では、ボルト１６の頭部１６ａは工具で回転させるように構成したが、施工者が手で回転できるように、つまみ部を形成してもよい。
また、本実施形態では、掛止部を掛止受部に掛止させるにあたり、掛止部をタンク側面に近づく方向に移動させるように構成したが、これとは逆に掛止部をタンク側面から遠ざかる方向に移動させることで掛止受部に掛止させるようにしてもよい。
Although this embodiment has been described in detail above, this is merely an example. For example, in the present embodiment, the head portion 16a of the bolt 16 is configured to be rotated by a tool, but a knob portion may be formed so that the installer can rotate the hand.
Further, in the present embodiment, when the latching portion is latched to the latch receiving portion, the latching portion is configured to move in a direction approaching the side surface of the tank. You may make it latch on a latch receiving part by moving to the direction away from.
