Description

本発明は、浴槽に取り付け及び取り外しが可能であり、浴槽の側壁に取り付けた際に適度の取付力を保持するのに好適な浴槽用手摺りに関する。 TECHNICAL FIELD The present invention relates to a bathtub handrail that can be attached to and removed from a bathtub, and that is suitable for maintaining an appropriate mounting force when attached to the side wall of the bathtub.

浴槽に手摺りを取り付ける際に過度な締付力を防止したものとしては、特許文献１，２等が公知である。
特許文献１は、浴槽の両側の側壁の内側に突っ張り力にて取り付ける入浴補助具を開示し、突っ張り力を伝達するばねの撓み量が一定値を超えると、突っ張り力を発生させる機構が空回りするものである。
しかし、同公報に開示する入浴補助具は、浴槽の両側の側壁に跨がるように取り付けられるので、入浴スペースが狭くなる。
また、取り付け位置に制限が生じる。 Japanese Unexamined Patent Application Publication Nos. 2003-100000 and 2003-100003 disclose a handrail that prevents an excessive tightening force when attaching a handrail to a bathtub.
Patent Document 1 discloses a bathing aid that is attached to the inside of both side walls of a bathtub with a tension force, and when the amount of deflection of a spring that transmits the tension force exceeds a certain value, the mechanism that generates the tension force idles. It is.
However, the bathing aid disclosed in this publication is attached so as to straddle the side walls on both sides of the bathtub, so that the bathing space becomes narrow.
Also, there are restrictions on the mounting position.

これに対して特許文献２には、片側の側壁に固定できる浴槽用手摺りを開示する。
しかし、同公報に開示する取付構造にあっては、ノブを本体フレームの垂直部に取り付けた構造になっているので、この取付部を覆うためのカバーが必要になる。
これでは、カバー内部に水が溜まりやすく、水垢やカビが発生した場合の除去が大変である。
特に特許文献２には、突出したボルト軸を収容するための室をノブの内側に有しているため、この室に水が浸入しやすく、室に水垢やカビが発生すると異臭の原因になるだけでなく、ボルト軸が廻りにくくなる不具合が発生しやすい技術的課題がある。 On the other hand, Patent Literature 2 discloses a bathtub handrail that can be fixed to one side wall.
However, in the mounting structure disclosed in the publication, since the knob is mounted on the vertical portion of the body frame, a cover is required to cover the mounting portion.
As a result, water tends to accumulate inside the cover, and it is difficult to remove scale and mold when they occur.
In particular, Patent Document 2 has a chamber inside the knob for housing the protruding bolt shaft, so water easily enters this chamber, and water stains and mold build up in the chamber, causing a foul odor. In addition, there is a technical problem that the bolt shaft becomes difficult to turn.

本発明は、構造がコンパクトで取り付け安定性に優れた浴槽用手摺りの提供を目的とする。 SUMMARY OF THE INVENTION An object of the present invention is to provide a handrail for a bathtub that has a compact structure and excellent mounting stability.

本発明に係る浴槽用手摺りは、浴槽の側壁に取り付けるための手摺りであって、浴槽側壁に位置させる本体部に設けた垂直部材と、前記垂直部材に対向配置した対向部材とを備え、前記対向部材は前記垂直部材に向けて前進及び後退移動可能に取り付けた固定板を有し、前記固定板と前記垂直部材との間に浴槽側壁を挟み込むものであり、前記固定板を前進及び後退移動可能にした押え機構は前記対向部材に回動可能に取り付けた袋ナット部材と、前記固定板に取り付けた軸部材との螺合であり、前記袋ナット部材を回動操作する操作ノブを有し、前記袋ナット部材と操作ノブとの間に前記固定板に所定以上の押圧力が負荷されると空回りするトルク伝達機構を有することを特徴とする。
ここで本体部は、フレーム等を介してグリップを取り付けた手摺りの本体部をいい、必要に応じて対向部材等にサブグリップを取り付けてもよい。
本発明において上記本体部は、浴槽の外側でも内側でもよい。 A handrail for a bathtub according to the present invention is a handrail to be attached to a side wall of a bathtub, and comprises a vertical member provided on a main body positioned on the side wall of the bathtub, and a facing member arranged to face the vertical member, The facing member has a fixed plate mounted so as to be movable forward and backward toward the vertical member, and the side wall of the bathtub is sandwiched between the fixed plate and the vertical member, and the fixed plate is moved forward and backward. The presser mechanism made movable is screwed between a cap nut member rotatably attached to the opposing member and a shaft member attached to the fixing plate, and has an operation knob for rotating the cap nut member. Further, a torque transmission mechanism is provided between the cap nut member and the operation knob, the torque transmission mechanism being idly rotated when a predetermined pressing force or more is applied to the fixed plate.
Here, the body portion refers to the body portion of the handrail to which the grip is attached via a frame or the like, and a sub-grip may be attached to the opposing member or the like as necessary.
In the present invention, the main body may be outside or inside the bathtub.

本発明において、トルク伝達機構は袋ナット部材側のトルク伝達板とこれに圧接する操作ノブ側のトルク伝達板を有し、前記操作ノブ側のトルク伝達板は操作ノブ側に配設したスプリングの付勢力によるものであってよい。
この場合に、スプリングは前記操作ノブの項部側が開口したスプリング収容部に収容し、前記項部側の開口部はスプリングを押える押え部材を有し、前記押え部材は袋ナット部材に取り付けることができる。 In the present invention, the torque transmission mechanism has a torque transmission plate on the side of the cap nut member and a torque transmission plate on the side of the operation knob that presses against the torque transmission plate on the side of the operation knob. It may be due to biasing force.
In this case, the spring may be accommodated in a spring accommodating portion which is open on the neck side of the operation knob, the opening on the neck side may have a pressing member for pressing the spring, and the pressing member may be attached to the cap nut member. can.

操作ノブ側のトルク伝達板を袋ナット部材側のトルク伝達板に圧接させることで、操作ノブを締め付け方向に回動すると、このトルクが袋ナット部材に伝達され、袋ナット部材が廻る。
これにより、袋ナット部材に螺合されている軸部材が前進し、固定板も前進し、固定板と本体部側の垂直部材との間に浴槽側壁を挟み込むようにして固定される。
この場合に、操作ノブのスプリング収容部に収容されたスプリングの一端を袋ナット部材に取り付けた押え部材にて、このスプリングが縮小する方向に押え付けてあるので、このスプリングに付勢力が働き、操作ノブに取り付けたトルク伝達板を袋ナット部材側のトルク伝達板に向けて押し付けた状態になっている。
操作ノブを締め付け方向に回すことで固定板が浴槽側壁を押圧することになるが、所定以上の押圧力が働くと、その反発力が軸部材に生じる。
この反発力により、軸部材に螺合している袋ナット部材が後退し、それに伴いスプリングの一端を押えている押え部材が後退するので、一対のトルク伝達板の間に空回りが生じることになり、それ以上の押圧力が固定板に生じなくなる。 By pressing the torque transmission plate on the operation knob side against the torque transmission plate on the cap nut member side, when the operation knob is rotated in the tightening direction, this torque is transmitted to the cap nut member, and the cap nut member rotates.
As a result, the shaft member screwed to the cap nut member advances, the fixing plate also advances, and the side wall of the bathtub is sandwiched and fixed between the fixing plate and the vertical member on the main body side.
In this case, one end of the spring housed in the spring housing portion of the operation knob is pressed in the contraction direction by the pressing member attached to the cap nut member, so that the spring is biased, The torque transmission plate attached to the operation knob is pressed against the torque transmission plate on the cap nut member side.
When the operation knob is turned in the tightening direction, the fixed plate presses the side wall of the bathtub.
Due to this repulsive force, the cap nut member screwed to the shaft member retreats, and the pressing member that presses one end of the spring retreats accordingly, causing idle rotation between the pair of torque transmission plates. The above pressing force is no longer applied to the fixed plate.

本発明に係る浴槽用手摺りにあっては、対向部材に取り付けた袋ナット部材に固定板を前進及び後退移動させるための軸部材を螺合してある。
この点において、特許文献２がナットの後方からボルト軸が突出するのと構造が相違し、ノブにボルト軸を収容するための室も本発明には不要となる。
また、本発明においては袋ナットのため、軸部材が後方から突出することがないので、操作ノブにスプリングを収容させつつ、このスプリングの一端を押えるための押え部材を袋ナット部材に取り付けることができるため、構造がコンパクトになる。 In the bathtub handrail according to the present invention, the shaft member for advancing and retreating the fixing plate is screwed to the cap nut member attached to the opposing member.
In this respect, the structure differs from Patent Document 2 in which the bolt shaft protrudes from the rear of the nut, and the present invention also eliminates the need for a chamber for housing the bolt shaft in the knob.
Further, in the present invention, since the cap nut is used, the shaft member does not protrude from the rear. Therefore, while the spring is accommodated in the operation knob, a pressing member for holding down one end of the spring can be attached to the cap nut member. As a result, the structure becomes compact.

In this embodiment, elastic skin materials 13a, 14a and 24a are attached to the contact surfaces with the bathtub.
In this embodiment, a sub-grip 17 is attached to the opposing member 16 as shown in FIG.

次に、操作ノブの回転による固定板２４の移動機構（押え機構）について説明する。
図２に断面図を示し、部品図を図３に示す。
袋ナット部材２２は内側に、めねじ部を形成しためねじ部材２２ａがインサートされている。
袋ナット部材２２は、対向部材１６の装着孔１６ａに装着したスリーブ２２ｂとピン２２ｃにて、ピン止めされている。
スリーブ２２ｂは、装着孔１６ａよりも外径が大きいつば部１２２ｂを有し、対向部材１６と直交する方向に所定のアソビを形成しながら、袋ナット部材２２と連結されている。
めねじ部材２２ａには、おねじ部２３ａを有する軸部材２３が螺合され、この軸部材２３の先端側に固定板２４が座２４ｂを介してネジ部材２４ｃにて取り付けられている。 Next, a moving mechanism (holding mechanism) for the fixing plate 24 by rotating the operation knob will be described.
A sectional view is shown in FIG. 2, and a part drawing is shown in FIG.
The cap nut member 22 has an internal thread formed therein and an internal thread member 22a inserted therein.
The cap nut member 22 is pinned by a sleeve 22b mounted in the mounting hole 16a of the facing member 16 and a pin 22c.
The sleeve 22b has a flange portion 122b with a larger outer diameter than the mounting hole 16a, and is connected to the cap nut member 22 while forming a predetermined play in a direction orthogonal to the opposing member 16. As shown in FIG.
A shaft member 23 having an externally threaded portion 23a is screwed into the female threaded member 22a, and a fixing plate 24 is attached to the distal end side of the shaft member 23 with a screw member 24c via a seat 24b.

操作ノブ２１は、項部側が開口した回動軸中心と同心円状に形成したスプリング収容部２１ａを有し、この中にスプリング２５を挿入し、このスプリング２５を圧縮させた状態で押え部材２６を袋ナット部材２２の端部（項部）に座２６ｃを介して、ボルト２６ｂとナット２６ａにて取り付けてある。
これにより、操作ノブ２１は対向部材１６側に向けて付勢されている。
本実施例では、押え部材２６にノブカバー２７を取り付けてある。 The operation knob 21 has a spring accommodating portion 21a formed concentrically with the center of the rotation shaft and having an opening at the neck side. It is attached to the end (neck) of the cap nut member 22 with a bolt 26b and a nut 26a via a seat 26c.
Thereby, the operation knob 21 is biased toward the opposing member 16 side.
In this embodiment, a knob cover 27 is attached to the holding member 26 .

袋ナット部材２２の外周部には、段差状の六角形状からなる回り止め部２２ｄを形成し、この回り止め部２２ｄの部分にスペーサー３２ａを嵌着し、このスペーサー３２ａに袋ナット部材側のトルク伝達板３２をピン３２ｂで、ピン止めしてある。
一方、操作ノブ２１の対向部材側の内側に、廻り止めを目的に六角形状にしたスペーサー３１ａを嵌着し、このスペーサー３１ａに操作ノブ側のトルク伝達板３１をピン３１ｂにてピン止めしてある。
これにより、操作ノブ２１を締め付け方向に回すと、スプリング２５の付勢力により、操作ノブ側トルク伝達板と、袋ナット部材側トルク伝達板が圧接しているので、このトルク伝達板を介して袋ナット部材２２がスリーブ２２ｂと装着孔１６ａとの間を摺動部として回動する。
これにより、袋ナット部材２２に螺合されている軸部材２３が突出方向に前進し、固定板２４と垂直部材１３との間に、浴槽側壁１を挟み込むことになる。
操作ノブ２１の締め付け力が所定の値よりも大きくなると、固定板２４の浴槽側壁１に対する反発力も所定の値よりも大きくなる。
この力が袋ナット部材２２に伝達され、スプリング２５の押え部材２６が後退するので、スプリング２５の付勢力が弱くなることで、一対のトルク伝達板３１，３２が、相対的に空回りするようになるので、固定板２４に所定以上の押圧力が発現するのを抑えることができる。 A stepped hexagonal anti-rotation portion 22d is formed on the outer peripheral portion of the cap nut member 22, and a spacer 32a is fitted to the portion of the anti-rotation portion 22d. The transmission plate 32 is pinned with a pin 32b.
On the other hand, a hexagonal spacer 31a is fitted to the inside of the operation knob 21 on the opposite member side for the purpose of preventing rotation, and the torque transmission plate 31 on the operation knob side is pinned to the spacer 31a with a pin 31b. be.
As a result, when the operation knob 21 is turned in the tightening direction, the force of the spring 25 presses the torque transmission plate on the operation knob side and the torque transmission plate on the cap nut member side. The nut member 22 rotates as a sliding portion between the sleeve 22b and the mounting hole 16a.
As a result, the shaft member 23 screwed to the cap nut member 22 advances in the protruding direction, and the bathtub side wall 1 is sandwiched between the fixing plate 24 and the vertical member 13 .
When the tightening force of the operation knob 21 becomes larger than a predetermined value, the repulsive force of the fixing plate 24 against the side wall 1 of the bathtub also becomes larger than a predetermined value.
This force is transmitted to the cap nut member 22, and the pressing member 26 of the spring 25 retreats, so that the urging force of the spring 25 is weakened, so that the pair of torque transmission plates 31 and 32 relatively idle. Therefore, it is possible to suppress the pressing force exceeding a predetermined value from being applied to the fixing plate 24 .
