Description

この発明は、建物等の出入口開口を水平姿勢で横切るように建物の壁面に設置された回動手摺り材を、その一端を支点として回動可能に構成して、出入口開口を使用時には鉛直姿勢に退避させ、且つその位置に固定して使用可能な可動式手摺り構造の技術分野に属する。 In this invention, a rotating handrail material installed on the wall surface of a building so as to cross the entrance opening of a building or the like in a horizontal posture is configured to be rotatable with one end as a fulcrum, and the entrance opening is in a vertical posture when used. The present invention belongs to the technical field of a movable handrail structure that can be retracted and used in a fixed position.

従来から、高齢者やリハビリテーションを行っている要介護者は、自力で家や公共施設等の建物内を移動する方法として、その壁面に沿って設けられる手摺り材を伝い歩くことが広く行われている。要介護者は、僅かな距離であっても手摺り材が設置されていないと移動が困難であり、転倒事故につながる虞がある。そのため、出入口開口を使用する際に鉛直姿勢に退避可能な回動手摺り材を使用して建物の壁面に水平方向に連続した手摺り材を設けることが実用に供されている。 Conventionally, elderly people and care recipients who are performing rehabilitation have often been walking along handrails provided along their walls as a method of moving on their own in buildings such as homes and public facilities. ing. The care recipient is difficult to move without handrails even at a short distance, which may lead to a fall accident. Therefore, it is practically used to provide a handrail material that is continuous in the horizontal direction on the wall surface of the building using a rotating handrail material that can be retracted to a vertical posture when using the entrance opening.

上記のような手摺り構造が特許文献１に開示されて公知である。図１４Ａに例示したように、出入口開口の横幅の長さに形成された回動手摺り材１３の一端が壁面に固定された固定具１４を支点１５として回動可能に取り付けられ、同回動手摺り材１３の水平姿勢または鉛直姿勢を固定して使用可能な構成とされている。したがって、通常時には固定具１４と反対方向の壁面に設けた保持材１６で回動手摺り材１３の水平姿勢を固定して連続的に設置でき、出入口開口を使用する際には、回動手摺り材１３を回動して持ち上げて出入口開口の脇へ退避させその鉛直姿勢を固定できる。鉛直姿勢の固定手段は、図１４Ｂに示すように、壁面に取り付けた保持具１７（ブラケット）内へ、回動手摺り材１３の支点１５の反対側の端部に形成された掛止具１８が掛け止められて固定される。
特許第３５８５４２３号公報 The handrail structure as described above is disclosed in Patent Document 1 and is known. As illustrated in FIG. 14A, one end of a rotating handrail member 13 formed to have a lateral width of the entrance opening is rotatably mounted with a fixing tool 14 fixed to the wall surface as a fulcrum 15. The horizontal posture or the vertical posture of the material 13 is fixed and can be used. Therefore, normally, the horizontal position of the rotating handrail material 13 can be fixed and continuously installed by the holding material 16 provided on the wall surface opposite to the fixing tool 14, and the rotating handrail material can be used when using the entrance opening. 13 can be rotated and lifted to retract to the side of the entrance / exit opening to fix the vertical posture. As shown in FIG. 14B, the vertical posture fixing means includes a hook 18 formed at the end opposite to the fulcrum 15 of the rotating handrail 13 in a holder 17 (bracket) attached to the wall surface. It is locked and fixed.
Japanese Patent No. 3585423

上記特許文献１の可動式手摺り構造は、出入口開口においても回動手摺り材１３を水平方向に連続して設け、出入口開口の使用を妨げない効果は認められる。しかし、回動手摺り材１３を鉛直姿勢に固定するために設置される保持具１７（ブラケット）の高さ位置は、回動手摺り材１３の端部に設けられる掛止具１８との関係から、出入口開口の横幅の長さに形成された回動手摺り材１３のスパンにより決定されることになる。その為、保持具１７の高さ調節ができず、回動手摺り材１３の長さ次第では顔の高さ位置（目など）にくる場合があり大変危険である。また、保持具１７（ブラケット）は壁からの出幅が回動手摺り材１３より出っ張る形状とされているため、出入口開口を人や物が出入りする際に利用者が体を傷つけてしまったり服を引っかけたりする虞があり危険である。特に要介護者にとっては服を引っ掛ける程度の些細な事でも転倒して大事故につながる虞があるため見過ごすことはできない問題である。 The movable handrail structure of the above-mentioned patent document 1 is provided with the rotating handrail material 13 continuously in the horizontal direction even at the entrance / exit opening, and the effect that does not hinder the use of the entrance / exit opening is recognized. However, the height position of the holder 17 (bracket) installed to fix the rotating handrail material 13 in the vertical posture is based on the relationship with the hook 18 provided at the end of the rotating handrail material 13. It is determined by the span of the rotating handrail material 13 formed in the width of the entrance / exit opening. For this reason, the height of the holder 17 cannot be adjusted, and depending on the length of the rotating handrail member 13, the height of the face (eg eyes) may be reached, which is very dangerous. Moreover, since the holder 17 (bracket) has a shape in which the protruding width from the wall protrudes from the rotating handrail material 13, the user may injure the body when a person or an object enters or exits the entrance / exit opening. There is a risk of catching. This is a problem that can not be overlooked, especially for those who need care, because even a trivial matter of getting caught can fall and lead to a major accident.

回動可能な支点１５の位置としては、家具等の配置位置や利用者の障害の程度等々を考慮すると、右側のみならず左側にも取り付ける場合が当然考えられる。しかし、水平方向に連続するような手摺りを取り付ける場合、壁への取り付け部に対し、固定手段に対称性がないこと、また前記回動手摺り材１３と掛止具１８とが一体形成されているので、左側に支点１５を設けようとした場合に兼用ができない。したがって、左側に支点１５を設ける場合には、各部材を左側専用に成型して実施しなければならず非常に面倒であるし、左側専用部材、右側専用部材が必要となりその商品点数が多くなり在庫管理等が大変となる。 As a position of the pivotable fulcrum 15, it is naturally conceivable that it is attached not only on the right side but also on the left side in consideration of the arrangement position of furniture and the like, the degree of obstacle of the user, and the like. However, when a handrail that is continuous in the horizontal direction is attached, the fixing means is not symmetrical with respect to the attachment portion to the wall, and the rotating handrail material 13 and the latching tool 18 are integrally formed. Therefore, when it is going to provide the fulcrum 15 on the left side, it cannot be combined. Therefore, when the fulcrum 15 is provided on the left side, each member must be molded exclusively for the left side, which is very troublesome, and the left side dedicated member and the right side dedicated member are required, which increases the number of products. Inventory management becomes difficult.

また、回動可能な支点１５が特殊な形状で複雑な構成の部材とされているが故に、例えば図１、図１３のような取り付けを実施するには、更に特殊で複雑な構成の部材が必要となり制作費が嵩みコスト高である。 Further, since the pivotable fulcrum 15 is a member having a special shape and a complicated configuration, for example, in order to perform the attachment as shown in FIGS. 1 and 13, a member having a more special and complicated configuration is required. It is necessary and the production cost is high and the cost is high.

上記回動手摺り材１３の一側に連結された固定具１４は、図１４Ａ又は同公報の図５、図６に示すようにその他側が壁面に固定される構成である。しかし、前記固定具１４の他側は出入口開口の左右に隣接される別の手摺り材又はブラケットとする支持具に連結される場合がある。そのため、特許文献１の可動式手摺り構造は、出入口開口の左右の設置環境に自在に適合させることはできず、適合させるには、固定具１４の他側の形状を取り付け環境に合わせたものが数種類必要となり、現場での左右変更等の細かな対応が至難で作業効率が悪い。 As shown in FIG. 14A or FIGS. 5 and 6 of the same publication, the other side of the fixture 14 connected to one side of the rotating handrail material 13 is configured to be fixed to the wall surface. However, the other side of the fixture 14 may be connected to a support tool that is another handrail material or bracket adjacent to the left and right of the entrance opening. Therefore, the movable handrail structure of Patent Document 1 cannot be freely adapted to the installation environment on the left and right sides of the entrance / exit opening, and in order to adapt, the shape on the other side of the fixture 14 is adapted to the installation environment. Is necessary, and it is difficult to make detailed responses such as changing left and right on site, and work efficiency is poor.

本発明の目的は、安全性が高く、左右に兼用可能として商品点数を少なくし、単純な構成で、コストを低減でき、出入口開口の利用に至便で、左右の設置環境に合わせた様々なパターンを実施可能な可動式手摺り構造を提供することにある。 The object of the present invention is high safety, can be used for both left and right, reduces the number of products, reduces the cost with a simple configuration, is convenient for the use of the entrance and exit, and various patterns according to the installation environment on the left and right It is in providing the movable handrail structure which can implement.

The joint plate 32 is provided with pin holes 33 and 33 in an arrangement perpendicular to the axial direction, and further, a step portion 32a is formed on the upper surface thereof.

前記円筒部３１を支持する支持具６は、建物の壁面に沿って固定され水平方向に出入口開口Ｋの手前位置まで配置された別の（既存の）手摺り材としており、同手摺り材２の端部へ前記支持ソケット部材３０の円筒部３１を差し入れて連結し、建物の壁面に沿って水平方向に連続した手摺り構造を実施できる。勿論この限りではなく、図１３に示すように、支持具６’が出入口開口Ｋの両脇壁面Ｗに固定されるＬ形状のブラケット材６’の場合には、同ブラケット材６’の先端へ支持ソケット３０部の円筒部３１を差し入れて連結される。図示の通り回動手摺り材２の反対側の端部は掛け止め部７の支持部７０とブラケット材６’とが連結する構成として実施できる。上記のようにして出入口開口の両側の取り付け環境に適合させて様々な実施パターンで適用できる。
The support 6 that supports the cylindrical portion 31 is another (existing) handrail material that is fixed along the wall surface of the building and is disposed in the horizontal direction up to the position before the entrance opening K. The handrail material 2 to end coupled pledged cylindrical portion 31 of the supporting socket member 30, Ru can be implemented a continuous handrail structure in the horizontal direction along the wall surface of the building. Of course, the present invention is not limited to this, and as shown in FIG. 13, in the case where the support member 6 ′ is an L-shaped bracket member 6 ′ fixed to both side wall surfaces W of the entrance / exit opening K, to the tip of the bracket member 6 ′. The cylindrical part 31 of the support socket 30 part is inserted and connected. As shown in the drawing, the opposite end portion of the rotating handrail material 2 can be implemented as a structure in which the support portion 70 of the latching portion 7 and the bracket material 6 'are connected. As described above, it can be applied in various implementation patterns by adapting to the installation environment on both sides of the entrance opening.

上記のような構成の回動用手摺り連結部３は、前記支持ソケット部材３０のジョイント板３２、３２と回動ソケット部材３４のジョイント板３６とを互い違いに組み合わせて、それぞれのピン孔３３と長孔３７へピン５を差し渡して回動可能に連結したジョイント機構を形成する。 The pivoting handrail connecting portion 3 having the above-described configuration is obtained by alternately combining the joint plates 32 and 32 of the support socket member 30 and the joint plate 36 of the pivoting socket member 34 to each of the pin holes 33 and the lengths. A joint mechanism is formed in which the pin 5 is passed through the hole 37 and is rotatably connected.

次に、回動用手摺り連結部３が回動する原理について図５、図６から説明する。
回動ソケット部材３４は、図５に示すように、長孔３７の範囲内で差し込まれたピン５を移動させて回動することが可能である。更に云うと同長孔３７の先端部寄り（図示では左端）であると、回動ソケット部材３４はスムーズに上下方向に１８０度回動可能となる。因みに、回動手摺り材２が水平姿勢に固定される状態は、回動ソケット部材３４の長孔３７のピン５の位置が先端寄りとなっており、上記掛け止め部７を掛け外せば直ちに回動可能な状態にある。 Next, the principle of rotation of the handrail connecting portion 3 for rotation will be described with reference to FIGS.
As shown in FIG. 5, the rotating socket member 34 can be rotated by moving the pin 5 inserted in the range of the long hole 37. Furthermore, if it is closer to the tip of the elongated hole 37 (the left end in the figure), the rotating socket member 34 can smoothly rotate 180 degrees in the vertical direction. Incidentally, the state in which the rotating handrail material 2 is fixed in the horizontal position is such that the position of the pin 5 of the elongated hole 37 of the rotating socket member 34 is closer to the tip, and the rotation immediately after the hooking portion 7 is detached. It is ready to move.

そして、図６Ａが示すように、図５の如くピン５の位置を先端寄りのまま回動手摺り材２を鉛直方向に回動して立てた後、図６Ｂが示すように、回動手摺り材２を下方位置へ下ろして、回動ソケット部材３４の長孔３７のピン５の位置を内端寄り（図示では上端）へ移動させる。すると、回動ソケット部材３４の円筒部３５の下端面が支持ソケット部材３０の段差部３２ａの上端面へ載置されて、回動ソケット部材３４、もっては回動手摺り材２の鉛直姿勢を支持できる。 Then, as shown in FIG. 6A, after the rotating handrail material 2 is turned upright while keeping the position of the pin 5 close to the tip as shown in FIG. 5, the rotating handrail material as shown in FIG. 6B. 2 is lowered to a lower position, and the position of the pin 5 of the long hole 37 of the rotary socket member 34 is moved closer to the inner end (upper end in the drawing). Then, the lower end surface of the cylindrical portion 35 of the rotating socket member 34 is placed on the upper end surface of the stepped portion 32 a of the supporting socket member 30 to support the vertical posture of the rotating socket member 34 and thus the rotating handrail material 2. it can.

次に、上記鉛直姿勢固定部４について説明する。
鉛直姿勢固定部４は、図３に示すように、回動手摺り材２を鉛直姿勢に固定するものである。その構成は、図３、図７に示すように、支持ブラケット部材４０と、回動手摺り材２の他端寄り位置へ取り付けた、前記支持ブラケット部材４０で支持・固定される被支持部材４１とで成る別物品として構成されている。被支持部材４１は端的に言うと、回動手摺り材２の支持ブラケット部材４０と接触する高さ位置へ挿入され取り付けられている。
したがって、前記鉛直姿勢固定部４は従来のように手摺り材の先端の掛け止め部７へ設けないので、前記被支持部材４１と支持ブラケット部材４０の取り付け位置が、回動手摺り材２の長さで決定されることなく、利用者に危険の及ばない高さ位置に任意に設置できる。 Next, the vertical posture fixing unit 4 will be described.
As shown in FIG. 3, the vertical posture fixing unit 4 fixes the rotating handrail material 2 to a vertical posture. As shown in FIGS. 3 and 7, the configuration includes a support bracket member 40 and a supported member 41 supported and fixed by the support bracket member 40 attached to a position near the other end of the rotating handrail material 2. It is comprised as another article which consists of. In short, the supported member 41 is inserted and attached to a height position in contact with the support bracket member 40 of the rotating handrail material 2.
Therefore, since the vertical posture fixing part 4 is not provided on the latching part 7 at the tip of the handrail material as in the prior art, the mounting position of the supported member 41 and the support bracket member 40 is the length of the rotating handrail material 2. Without being determined, it can be installed arbitrarily at a height that does not pose a danger to the user.

前記支持ブラケット部材４０は、一側端（基端）に壁面Ｗへ固定可能な円形状の取り付け部４０ａを有しており、同取り付け部４０ａに設けられたねじ穴へねじ等を締め込んで前記壁面Ｗの安全な高さ位置に取り付ける（図示省略）。また、支持ブラケット部材４０からＬ字形状に伸びる腕部４０ｂが形成されている。同腕部４０ｂの先端には、被支持部材４１を受ける受け部４０ｃが平面視を１／４円弧形状に形成されている。 The support bracket member 40 has a circular mounting portion 40a that can be fixed to the wall surface W at one side end (base end), and a screw or the like is tightened into a screw hole provided in the mounting portion 40a. It is attached to a safe height position of the wall surface W (not shown). Further, an arm portion 40b extending in an L shape from the support bracket member 40 is formed. A receiving portion 40c that receives the supported member 41 is formed in a ¼ arc shape in plan view at the tip of the arm portion 40b.

本発明のロック機構は、前記受け部４０ｃの受け面及び被支持部材の外面のいずれか一方には溝を、他方には突起を設けて掛け止めする構成とされている。例えば、図７には被支持部材４１に溝４１ａを、支持ブラケット部材４０に突起４０ｄを設けた例を示した。
前記被支持部材４１の溝４１ａはその下端部が幅広に形成され且つ直径Ｘに対して左右対称な位置に設けられている。対する支持ブラケット部材４０の突起４１ｄは前記溝４１ａに対応する位置と形状で且つ支持ブラケット部材全体を通る中心面Ｙに対して上下対称に形成されている。 The locking mechanism of the present invention is configured to be latched by providing a groove on one of the receiving surface of the receiving portion 40c and the outer surface of the supported member and a protrusion on the other. For example, FIG. 7 shows an example in which the supported member 41 is provided with a groove 41a and the support bracket member 40 is provided with a protrusion 40d.
The groove 41a of the supported member 41 has a lower end formed wide and is provided at a position symmetrical with respect to the diameter X. The protrusion 41d of the support bracket member 40 is formed in a position and shape corresponding to the groove 41a and symmetrically with respect to the center plane Y passing through the entire support bracket member.

もちろん、上記の限りではなく、突起と溝を反対に取り付けて実施することも考えられる。つまり、図８に示すように、被支持部材４１側に突起４１ａ’を、支持ブラケット部材４０側に溝４０ｄ’を設けて実施できる。つまり、被支持部材４１の突起４１ａ’は直径Ｘに対して左右対称な位置に設け、支持ブラケット部材４０の溝４０ｄ’は前記突起４１ａ’を挿入可能な溝幅を上下方向に亘って設け、溝の中間位置には水平方向の止め具Ｓを設け、前記突起４１ａ’と対応する位置で且つ支持ブラケット部材４０全体を通る中心面Ｙ（図７と同様のため図示省略）に対して上下対称に形成する構成である。この限りではなく上述した前記被支持部材４１の外面に直径に対して左右対称な位置で設けられる溝４１ａ（図７）が、前記支持ブラケット部材４０の溝４０ｄ’の形状と略同様に、突起を挿入可能な溝幅を上下方向に亘って設け、溝の中間位置には水平方向の止め具を設けたＨ型形状に形成して実施しても良い（請求項６記載の発明）。
上記のような形状又は配置とされた溝又は突起に構成したので、図１１Ａ、図１１Ｂに示すように出入口開口Ｋの左右のいずれの壁面Ｗにおいても１８０度反転すれば容易に兼用でき、支持ブラケット部材４０と被支持部材４１は一種類の形状品でよくなり商品点数を少なくして在庫及びその管理を簡略化し施工も容易ならしめる。

Of course, the present invention is not limited to the above, and it is also conceivable that the projection and the groove are attached in the opposite direction. That is, as shown in FIG. 8, the protrusion 41a ′ can be provided on the supported member 41 side, and the groove 40d ′ can be provided on the support bracket member 40 side. That is, the protrusion 41a ′ of the supported member 41 is provided at a position symmetrical with respect to the diameter X, and the groove 40d ′ of the support bracket member 40 is provided with a groove width in which the protrusion 41a ′ can be inserted in the vertical direction. A horizontal stopper S is provided at an intermediate position of the groove, and is vertically symmetrical with respect to a center plane Y (not shown for the same reason as FIG. 7) at a position corresponding to the protrusion 41a ′ and passing through the entire support bracket member 40. It is the structure formed in. However, the groove 41a (FIG. 7) provided on the outer surface of the supported member 41 at a position symmetrical to the diameter is not limited to the above, and is substantially the same as the shape of the groove 40d ′ of the support bracket member 40. It is also possible to form the groove in such a manner that the width of the groove can be inserted in the up-down direction and is formed in an H shape with a horizontal stopper provided at the middle position of the groove (invention of claim 6 ).
Since the grooves or protrusions having the shape or arrangement as described above are configured, as shown in FIG. 11A and FIG. The bracket member 40 and the supported member 41 need only be one type of product, and the number of products can be reduced to simplify the inventory and management thereof and make the construction easier.

次に、溝と突起とを掛け止める方法について、図５、図６、図９から説明する。
即ち、図５、図６Ａに示した如く、回動手摺り材２は、回動用手摺り連結部３の長孔３７のピン５の位置を先端寄りを保持したまま鉛直方向に立てられると、図９Ａに示すように回動手摺り材２に取り付けた被支持部材４１の高さ位置が支持ブラケット部材４０の高さ位置よりも高くなる。そして、図６Ｂの如く回動手摺り材２を下方へ下ろして、ピン５をジョイント板３２の長孔３７の下方位置（内端寄り）へ落とすと、図９Ｂに示すように、被支持部材４１の溝４１ａ内に支持ブラケット部材４０の突起４０ｄが落とし込まれて掛け止められると同時に図６Ｂの如く回動用手摺り連結部３の支持ソケット部材３０の段差部３２ａの上端面に円筒部３５の下端部が載置される。斯くして、回動用手摺り連結部３と、固定用手摺り支持ソケット４とを溝に突起を掛け止めて回動手摺り材２の鉛直姿勢を支持・固定する作業を回動手摺り材２の上下の動作のみで行えるのである。 Next, a method for latching the groove and the protrusion will be described with reference to FIGS.
That is, as shown in FIGS. 5 and 6A, when the rotating handrail material 2 is set up in the vertical direction while the position of the pin 5 of the elongated hole 37 of the rotating handrail connecting portion 3 is held close to the tip, As shown in 9A, the height position of the supported member 41 attached to the rotating handrail member 2 is higher than the height position of the support bracket member 40. Then, when the rotating handrail material 2 is lowered downward as shown in FIG. 6B and the pin 5 is dropped to the lower position (close to the inner end) of the long hole 37 of the joint plate 32, as shown in FIG. The projection 40d of the support bracket member 40 is dropped into the groove 41a and latched, and at the same time, the cylindrical portion 35 is formed on the upper end surface of the step portion 32a of the support socket member 30 of the handrail connecting portion 3 for rotation as shown in FIG. 6B. The lower end is placed. Thus, the operation of supporting and fixing the vertical posture of the rotating handrail material 2 by holding the protrusion on the groove of the rotating handrail connecting portion 3 and the fixing handrail support socket 4 in the groove is performed on the rotating handrail material 2. It can be done only by moving up and down.

前記支持ブラケット部材４０の受け部４０ｃは、図１０に示すように、壁面Ｗの位置から見てＬ字形状の腕部４０ｂよりも前方に突き出ない形状としている。つまり、壁面Ｗからの出幅Ｈ１を回動手摺り材２の出幅Ｈ２より出っ張らない形状である。したがって、出入口開口を使用する利用者、特に要介護者が支持ブラケット部材４０に体や服を引っかける虞を防止し安全性を確保できる。 As shown in FIG. 10, the receiving portion 40 c of the support bracket member 40 has a shape that does not protrude forward from the L-shaped arm portion 40 b when viewed from the position of the wall surface W. That is, the protruding width H <b> 1 from the wall surface W does not protrude from the protruding width H <b> 2 of the rotating handrail material 2. Therefore, it is possible to prevent a user who uses the entrance / exit opening, particularly a care recipient, from catching a body or clothes on the support bracket member 40 and to secure safety.

図１２には、図７の構成で掛け止められた支持ブラケット部材４０と被支持部材４１とが万が一外れる虞があることを考慮して安全ストッパー８を取り付けた一例を示した。 FIG. 12 shows an example in which the safety stopper 8 is attached in consideration of the possibility that the support bracket member 40 and the supported member 41 latched in the configuration of FIG.

前記安全ストッパー８は受け部４０ｃの背面位置に設けられ、上げ下げ可能なノブ８０と、同ノブ８０と連結され且つ受け部４０ｃ内を貫通し、被支持部材４１の溝４１ａ、４１ａの中間位置に設けた貫通孔４１ｂへその内周面から出ない位置まで差し込んで固定する心棒８１と、前記心棒８１の両脇に配置されノブ８０の上げ下げにより前記貫通孔４１ｂへの出し入れを調整可能とするバネ８２とから構成されている。したがって、被支持部材４１の溝４１ａと受け部４０ｃの突起４０ｄとを掛け止めた後、安全ストッパー８のノブ８０を下ろして心棒８１を被支持部材４１の貫通孔４１ｂへ挿入して固定する。取り外しは前記ノブ８０を上げて心棒８１を貫通孔４１ｂから引き抜けばよい。
勿論、図７の場合に限らず、図８に示す場合においても好適に実施して安全性を更に高めることも好適に実施される。 The safety stopper 8 is provided at the back surface of the receiving portion 40c, is connected to the knob 80 which can be raised and lowered, passes through the receiving portion 40c, and is positioned at an intermediate position between the grooves 41a and 41a of the supported member 41. A mandrel 81 that is inserted into and fixed to a through hole 41b that does not come out of its inner peripheral surface, and a spring that is disposed on both sides of the mandrel 81 and that can be adjusted to be inserted into and removed from the through hole 41b by raising and lowering the knob 80. 82. Therefore, after latching the groove 41a of the supported member 41 and the protrusion 40d of the receiving portion 40c, the knob 80 of the safety stopper 8 is lowered and the mandrel 81 is inserted into the through hole 41b of the supported member 41 and fixed. For removal, the knob 80 is raised and the mandrel 81 is pulled out of the through hole 41b.
Of course, not only the case of FIG. 7 but also the case shown in FIG.
