Description

本発明は、進退動作するロッドと、このロッドに対して着脱可能に取り付けられる作動子とを接続するための構造に関するものである。 The present invention relates to a structure for connecting a rod that moves forward and backward and an actuator that is detachably attached to the rod.

従来から、抽斗を内装する前面開放の躯体の上位に、該躯体の両側板に本体機構部を内蔵した昇降機構の支持部材にて支持された昇降天板を設けて成るようにした家具が知られている。 Conventionally, there has been known a furniture in which an elevating top plate supported by a support member of an elevating mechanism having a built-in main body mechanism is provided on both side plates of an upper body of a front open case that houses a drawer. It has been.

具体的にこの種の家具は、支持部材の下部の内側に沿って長尺板状の操作レバーを配設し、該操作レバーは、昇降天板の下面近傍からケースを貫通して延びており、前記昇降天板の両側下面に配したハンドルを操作して操作レバーを上方へ持ち上げることによって、該操作レバーがピニオン及びラチェットに接近する方向に平行移動するように支持部材に取り付けられている。そして、操作レバーの一側縁が、ケースに対して固定的な支軸に回動可能に設けた駒片を押して、当該駒片を板ばねの弾性付勢力に抗して回動させて、その爪をラチェットから引き離すようにしてある（例えば、特許文献１参照）。
特許第３４７８２９１号公報 Specifically, this type of furniture is provided with a long plate-like operation lever along the inside of the lower part of the support member, and the operation lever extends through the case from the vicinity of the lower surface of the lifting plate. The operation lever is attached to the support member so as to move in parallel in a direction approaching the pinion and the ratchet by operating the handles disposed on the lower surfaces of both sides of the elevating top plate and lifting the operation lever upward.

Japanese Patent No. 3478291

しかしながら、このようなものでは、例えば、組付けを簡単にするために、操作レバーに線条材を用いつつその先端部を折り曲げてＬ型に形成し、且つ、この操作レバーのＬ型部分を嵌装するための嵌装溝を駒片に設けて、これらを一体的に引っ張るようにしたものでは、操作レバーと駒片とが歪んだとき等に外れるといった不具合が生じるおそれがある。 However, in such a case, for example, in order to simplify the assembly, the distal end portion is bent into an L shape while using a wire rod for the operation lever, and the L shape portion of the operation lever is formed. In the case where the fitting groove for fitting is provided in the piece piece so that these pieces are pulled together, there is a possibility that a problem such as disconnection occurs when the operation lever and the piece piece are distorted or the like.

本発明は、このような課題に着目してなされたものであって、主たる目的は、組付けが簡単で且つ組付け時の高い組付け強度を無理なく確保可能な優れた部材の接続構造を提供することにある。 The present invention has been made paying attention to such problems, and the main purpose is to provide an excellent member connection structure that is easy to assemble and can ensure a high assembling strength without difficulty. It is to provide.

すなわち、本発明の部材の接続構造は、進退動作するロッドと、このロッドに対して着脱可能に取り付けられる作動子とを接続するための構造であって、前記ロッドが、ロッド本体と、このロッド本体の先端から屈曲する先端屈曲部とを具備し、前記作動子が、第1の方向から前記ロッド本体を取付可能に開成し且つ取付状態で前記ロッド本体の少なくとも一部を嵌装可能な第１の嵌装部と、前記第１の方向と異なる第２の方向から前記先端屈曲部を取付可能に開成し且つ取付状態で前記先端屈曲部の少なくとも一部を嵌装可能な第２の嵌装部と、前記第１の嵌装部側にある先端屈曲部を第２の嵌装部側へ挿通するための挿通部とを具備して成ることを特徴とする。 That is, the member connection structure of the present invention is a structure for connecting a rod that moves forward and backward and an actuator that is detachably attached to the rod. The rod includes a rod body and the rod. A bending portion that bends from the distal end of the main body, and the actuator is configured to open the rod main body from the first direction so that the rod main body can be attached and to be fitted with at least a part of the rod main body in the attached state. A first fitting portion and a second fitting capable of opening the tip bent portion so as to be attachable from a second direction different from the first direction and fitting at least a part of the tip bent portion in the attached state. It is characterized by comprising a mounting part and an insertion part for inserting the tip bending part on the first fitting part side into the second fitting part side.

このようなものであれば、ロッドと作動子との組立を、先端屈曲部を挿通部から第２嵌装部側に露出させた後、先端屈曲部の少なくとも一部を第２嵌装部に嵌装させ且つッド本体の少なくとも一部を第１嵌装部に嵌装させるといった簡単な方法で行うことができる。しかも、組み立てた状態では、各嵌装部は、異なる方向に向けて開成している上、ロッド本体と先端屈曲部とは互いに屈曲する関係にあるので、ロッドと作動子とを単に引っ張るだけでは外れることはない。 If it is such, after assembling the rod and the actuator, after exposing the tip bending portion from the insertion portion to the second fitting portion side, at least a part of the tip bending portion becomes the second fitting portion. It can be carried out by a simple method of fitting and at least a part of the lid main body to be fitted to the first fitting portion. Moreover, in the assembled state, each fitting portion is opened in a different direction, and the rod body and the tip bending portion are in a relationship of bending with each other, so simply pulling the rod and the actuator is not enough. It will not come off.

すなわち、組付けが簡単で且つ組付け時の高い組付け強度を無理なく確保可能な優れた部材の接続構造を提供することができる。 That is, it is possible to provide an excellent member connection structure that is easy to assemble and can ensure a high assembling strength without difficulty.

作動子の成形性を考慮したものとするには、前記第１の方向と前記第２の方向とが、略１８０度反転する関係にあることが望ましい。 In order to consider the moldability of the actuator, it is desirable that the first direction and the second direction are in a relationship of reversing approximately 180 degrees.

本発明のロッド及び作動子の望ましい態様としては、前記ロッドが、長手方向に各部略等断面形状を有する金属部材を塑性変形加工して形成したものであり、前記作動子が、弾性変形可能な合成樹脂により形成したものが挙げられる。 As a desirable mode of the rod and the actuator of the present invention, the rod is formed by plastic deformation processing of a metal member having substantially the same cross-sectional shape in the longitudinal direction, and the actuator is elastically deformable. The thing formed with the synthetic resin is mentioned.

前記第１の嵌装部及び前記第２の嵌装部が、前記ロッドの直径と略一致する幅寸法を有する溝状のものであれば、特別な締結部材を用いることなく、ロッドと作動子とを好適に組付けることができる。 If the first fitting portion and the second fitting portion are groove-shaped having a width dimension substantially matching the diameter of the rod, the rod and the actuator can be used without using a special fastening member. Can be suitably assembled.

以上説明したように本発明の部材の接続構造によれば、ロッドと作動子との組立を、先端屈曲部を挿通部から第２嵌装部側に露出させた後、先端屈曲部の少なくとも一部を第２嵌装部に嵌装させ且つッド本体の少なくとも一部を第１嵌装部に嵌装させるといった簡単な方法で行うことができる。しかも、組み立てた状態では、各嵌装部は、異なる方向に向けて開成している上、ロッド本体と先端屈曲部とは互いに屈曲する関係にあるので、ロッドと作動子とを単に引っ張るだけでは外れることはない。 As described above, according to the member connection structure of the present invention, after assembling the rod and the actuator, after exposing the bent end portion from the insertion portion to the second fitting portion side, at least one of the bent end portions. It is possible to carry out by a simple method of fitting the part to the second fitting part and fitting at least a part of the main body to the first fitting part. Moreover, in the assembled state, each fitting portion is opened in a different direction, and the rod body and the tip bending portion are in a relationship of bending with each other, so simply pulling the rod and the actuator is not enough. It will not come off.

しかして、昇降部材Ｆを静止部材Ｅに組み付けた状態において、静止部材Ｅの第１噛合部Ｈ２は、昇降部材Ｆのスライダ部材Ｍの第１厚肉部Ｍ２と第２厚肉部Ｍ３との間に位置し、第１歯部Ｈ２１が、スライダ部材Ｍの薄肉部Ｍ１に臨む位置に位置付けられた第２噛合部Ｎの各第２歯部Ｎ２にそれぞれ噛合し得る。第１噛合部Ｈ２と第２噛合部Ｎとが相互に噛合している場合、昇降部材Ｆの昇降移動は規制され、一方、第１噛合部Ｈ２と第２噛合部Ｎとの噛合状態が解除された場合、昇降部材Ｆの昇降移動は許容される。すなわち、第１噛合部Ｈ２と第２噛合部Ｎとを用いて、昇降部材Ｆの昇降移動を規制するロック状態又は昇降部材Ｆの昇降移動を許容するロック解除状態を取り得る噛合機構Ｇを構成している。 Thus, in a state where the elevating member F is assembled to the stationary member E, the first meshing portion H2 of the stationary member E is formed between the first thick portion M2 and the second thick portion M3 of the slider member M of the elevating member F. The first tooth portion H21 located between them can mesh with each second tooth portion N2 of the second meshing portion N positioned at a position facing the thin portion M1 of the slider member M. When the first meshing part H2 and the second meshing part N are meshed with each other, the lifting movement of the elevating member F is restricted, while the meshing state between the first meshing part H2 and the second meshing part N is released. In this case, the lifting / lowering member F is allowed to move up and down. That is, the first meshing portion H2 and the second meshing portion N are used to form a meshing mechanism G that can take a locked state that restricts the lifting movement of the lifting member F or a unlocked state that allows the lifting movement of the lifting member F. is doing.

本実施形態では、第１噛合部Ｈ２及び第２噛合部Ｎを相互に噛合可能な状態でスライダ部材Ｍと連結部材Ｑとの間に挟み込むことにより、第１噛合部Ｈ２と第２噛合部Ｎとが厚み方向に相対変位することを規制している（図８参照）。すなわち、連結部材Ｑが、第１噛合部Ｈ２及び第２噛合部Ｎをスライダ部材Ｍとの間で挟持し得る「挟持部材」としても機能し、これら連結部材Ｑ及びスライダ部材Ｍを用いて、「相対変位規制手段」を構成している。 In the present embodiment, the first meshing portion H2 and the second meshing portion N are sandwiched between the slider member M and the connecting member Q in a state where the first meshing portion H2 and the second meshing portion N can be meshed with each other. Restricts relative displacement in the thickness direction (see FIG. 8). That is, the connecting member Q also functions as a “holding member” that can hold the first engaging portion H2 and the second engaging portion N between the slider member M, and using the connecting member Q and the slider member M, It constitutes “relative displacement regulating means”.

前記第２噛合部Ｎは、図９に示すように、第１噛合部Ｈ２と噛合可能な噛合可能位置（同図（ａ−１）参照）と、第１噛合部Ｈ２との噛合状態を解除し得る噛合解除位置（同図（ｂ―１）参照）との間でスライダ部材Ｍと共に移動し、前記操作部Ｌの昇降レバーＬ１を上昇させる操作力が付与された場合に噛合解除位置を取り、前記操作力が停止された場合に噛合可能位置を取るように設定してある。 As shown in FIG. 9, the second meshing portion N releases the meshing state between the meshable position (see (a-1) in FIG. 9A) that can mesh with the first meshing portion H2 and the first meshing portion H2. When the operating force is applied to raise the lifting lever L1 of the operation portion L, the mesh releasing position is taken. When the operation force is stopped, the engagement position is set.

次に、図９を参照して、第２噛合部Ｎを噛合可能位置と噛合解除位置との間で移動させる方法及び作用について説明する。なお、図９における（ａ―２）、（ｂ−２）は、それぞれ同図（ａ―１）、（ｂ−１）を連結部材Ｑを省略して示す拡大図である。 Next, with reference to FIG. 9, a method and an action of moving the second meshing portion N between the meshable position and the mesh release position will be described. Note that (a-2) and (b-2) in FIG. 9 are enlarged views showing the same members (a-1) and (b-1) with the connecting member Q omitted.

先ず、第２噛合部Ｎを噛合可能位置（同図（ａ―１）参照）から噛合解除位置（同図（ｂ−１）参照）へ移動させるには、前記昇降レバーＬ１を上方に押し上げる操作力を付与することにより行う。この操作力に連動してロッドＲ及び連動部材Ｐが前記バネＳの付勢力に抗して上昇することによって、スライダ部材Ｍに対する連動部材Ｐの高さ位置が変位し、後述する第１凸部Ｍ５１と第２凸部Ｐ１１との当接状態が解除されるとともに、連動部材Ｐに設けたガイド用突起部Ｐ４１を連結部材Ｑのガイド用溝Ｑ２１の下接続片及び第１傾斜片に沿って案内させることにより、連結部材Ｑが前記干渉回避部Ｐ４を利用して連動部材Ｐに近寄る方向に巾方向に沿って移動し、これに伴ってスライダ部材Ｍも連結部材Ｑと共に連動部材Ｐに近寄る方向に巾方向に沿ってスライド移動する。この際、スライダ部材Ｍが、第１凹凸部Ｍ５と第２凹凸部Ｐ１が相互に係合し得る方向に沿って、その第２凹凸部Ｐ１の第２傾斜部Ｐ１２を連動部材Ｐの第１凹凸部Ｍ５の第１傾斜部Ｍ５２に摺動させることにより、スライダ部材Ｍの移動を確実に行うことができる。その結果、スライダ部材Ｍに保持された第２噛合部Ｎが、連動部材Ｐに近寄る方向、換言すれば第１噛合部Ｈ２から離間する方向に移動して第１噛合部Ｈ２と噛合し得ない噛合解除位置に位置付けられる。第２噛合部Ｎが噛合解除位置に位置付けられた場合、連結部材Ｑは、第１噛合部Ｈ２を被覆し得ない位置に位置付けられており、この連結部材Ｑとスライダ部材Ｍとによる第１噛合部Ｈ２の挟込状態が解除される。また、第１凹凸部Ｍ５及び第２凹凸部Ｐ１は、相互に係合した状態をとる（同図（ａ―２）参照）。 First, in order to move the second meshing portion N from the meshable position (see (a-1) in the figure) to the mesh release position (see (b-1) in the same figure), an operation of pushing up the lifting lever L1 upward. This is done by applying power. When the rod R and the interlocking member P are raised against the biasing force of the spring S in conjunction with this operating force, the height position of the interlocking member P with respect to the slider member M is displaced, and a first convex portion to be described later. The contact state between M51 and the second protrusion P11 is released, and the guide protrusion P41 provided on the interlocking member P is moved along the lower connecting piece and the first inclined piece of the guide groove Q21 of the connecting member Q. By guiding, the connecting member Q moves along the width direction in the direction approaching the interlocking member P using the interference avoiding part P4, and accordingly, the slider member M approaches the interlocking member P together with the connecting member Q. Slide along the width direction in the direction. At this time, the slider member M moves the second inclined portion P12 of the second uneven portion P1 along the direction in which the first uneven portion M5 and the second uneven portion P1 can engage with each other. The slider member M can be reliably moved by sliding on the first inclined portion M52 of the uneven portion M5. As a result, the second meshing portion N held by the slider member M cannot move in the direction approaching the interlocking member P, in other words, away from the first meshing portion H2, and cannot mesh with the first meshing portion H2. It is positioned at the mesh release position. When the second meshing portion N is positioned at the meshing release position, the connecting member Q is positioned at a position where the first meshing portion H2 cannot be covered, and the first meshing by the connecting member Q and the slider member M is performed. The sandwiched state of the part H2 is released. Moreover, the 1st uneven | corrugated | grooved part M5 and the 2nd uneven | corrugated | grooved part P1 take the state mutually engaged (refer the figure (a-2)).

一方、第２噛合部Ｎの噛合解除位置から噛合可能位置への移動は、前記操作力の停止、つまり昇降レバーＬ１から手を離す（又は操作力を弱める）動作に伴って行われる。昇降レバーＬ１から手を離すと、前記バネＳの弾性復帰力により連動部材Ｐ、ロッドＲ及び昇降レバーＬ１が元の位置（操作力付与前の位置）まで下降し、この連動部材Ｐの下降移動により、第１凹凸部Ｍ５の第１傾斜部Ｍ５２と第２凹凸部Ｐ１の第２傾斜部Ｐ１２とを相互に摺動させながらスライダ部材Ｍが連動部材Ｐから離間する方向に巾方向に沿って移動する。この際、連結部材Ｑが、そのガイド用溝Ｑ２１の上接続片及び第２傾斜片に沿って連動部材Ｐのガイド用突起部Ｐ４１を案内させることにより、スライダ部材Ｍの移動を確実に行うことができる。その結果、スライダ部材Ｍに保持された第２噛合部Ｎが、連動部材Ｐから離間する方向、換言すれば第１噛合部Ｈ２に近寄る方向に移動して第１噛合部Ｈ２と噛合可能な噛合可能位置に位置付けられる。第２噛合部Ｎが噛合可能位置に位置付けられた場合、第２噛合部Ｎの各第２歯部Ｎ２がそれぞれ対応する第１噛合部Ｈ２の第１歯部Ｈ２１と噛合する一方、スライダ部材Ｍに設けた第２凹凸部Ｐ１の第２凸部Ｐ１１と連動部材Ｐに設けた第１凹凸部Ｍ５の第１凸部Ｍ５１とがそれぞれフラット状の突出端部同士を相互に面的に当接させた状態となり、第２噛合部Ｎが噛合可能位置から噛合解除位置へ不意に移動しないように設定してある（同図（ｂ―２）参照）。すなわち、第１凸部Ｍ５１と、第２凸部Ｐ１１とを用いて、これら第１凸部Ｍ５１及び第２凸部Ｐ１１を相互に当接させることにより第２噛合部Ｎの係合可能位置から係合解除位置への退避移動を禁止する「ストッパ手段」を構成している。また、ガイド用溝Ｑ２１とガイド用突起部Ｐ４１との組み合わせ、及び、第１傾斜部Ｍ５２と第２傾斜部Ｐ１２との組み合わせにより、連動部材Ｐの昇降移動を、第２噛合部Ｎの噛合可能位置から噛合解除位置への移動又は噛合解除位置から噛合可能位置への移動に変換する「動作変換手段」を構成している。 On the other hand, the movement of the second meshing portion N from the mesh release position to the meshable position is performed with the stop of the operation force, that is, the operation of releasing the hand from the elevating lever L1 (or weakening the operation force). When the hand is released from the lifting lever L1, the interlocking member P, the rod R and the lifting lever L1 are lowered to the original position (position before the operation force is applied) by the elastic return force of the spring S, and the interlocking member P is moved downward. Accordingly, the slider member M moves along the width direction in a direction away from the interlocking member P while sliding the first inclined portion M52 of the first uneven portion M5 and the second inclined portion P12 of the second uneven portion P1. Moving. At this time, the connecting member Q guides the guide protrusion P41 of the interlocking member P along the upper connecting piece and the second inclined piece of the guide groove Q21, thereby reliably moving the slider member M. Can do. As a result, the second meshing portion N held by the slider member M moves in a direction away from the interlocking member P, in other words, in a direction approaching the first meshing portion H2, and can mesh with the first meshing portion H2. Positioned at a possible position. When the second meshing portion N is positioned at the meshable position, each second tooth portion N2 of the second meshing portion N meshes with the first tooth portion H21 of the corresponding first meshing portion H2, while the slider member M The second convex portion P11 of the second concave and convex portion P1 provided on the surface and the first convex portion M51 of the first concave and convex portion M5 provided on the interlocking member P are in contact with each other with the flat protruding ends. The second engagement portion N is set so as not to move unexpectedly from the meshable position to the mesh release position (see (b-2) in the figure). That is, by using the first convex portion M51 and the second convex portion P11, by bringing the first convex portion M51 and the second convex portion P11 into contact with each other, the second meshing portion N can be engaged from the position. “Stopper means” is configured to prohibit the retreat movement to the disengagement position. Further, the interlocking member P can be moved up and down by the combination of the guide groove Q21 and the guide protrusion P41 and the combination of the first inclined portion M52 and the second inclined portion P12, and the second engaging portion N can be engaged. “Operation conversion means” that converts the movement from the position to the mesh release position or the movement from the mesh release position to the meshable position is configured.

以下、ロッドＲと連動部材Ｐとを接続する方法について、以下に説明する。 Hereinafter, a method of connecting the rod R and the interlocking member P will be described below.

まず、ロッドＲの第５ロッド部Ｒ５を、連動部材Ｐの第１の嵌装部Ｐ２１側に位置づけ、しかる後、第５ロッド部Ｒ５を挿通部Ｐ２ａに挿通し、第２の嵌装部Ｐ２２側へ露出させる。そして、第４ロッド部Ｒ４をその長手方向と直交する方向に回動させれば、第５ロッド部Ｒ５を、第２の嵌装部Ｐ２２に嵌装することができる。さらに、この状態から、第４ロッド部Ｒ４を、第５ロッド部Ｒ５の軸中心を回動中心として回動させれば、第４ロッド部Ｒ４を第１の嵌装部Ｐ２１と第３の嵌装部Ｐ２３とにそれぞれ嵌装させることができる。 First, the fifth rod portion R5 of the rod R is positioned on the first fitting portion P21 side of the interlocking member P, and then the fifth rod portion R5 is inserted into the insertion portion P2a, and the second fitting portion P22 is inserted. Expose to the side. And if 4th rod part R4 is rotated in the direction orthogonal to the longitudinal direction, 5th rod part R5 can be fitted by the 2nd fitting part P22. Furthermore, from this state, if the fourth rod portion R4 is rotated about the axial center of the fifth rod portion R5, the fourth rod portion R4 is connected to the first fitting portion P21 and the third fitting portion. It can be made to fit in the mounting part P23, respectively.

このように、本実施形態に係る部材の接続構造Ｙは、ロッドＲと連動部材Ｐとの組立を、第５ロッド部Ｒ５を挿通部Ｐ２ａから第２の嵌装部Ｐ２２側に露出させた後、第５ロッド部Ｒ５を第２の嵌装部Ｐ２２に嵌装させ且つ第４ロッド部Ｒ４の少なくとも一部を第１の嵌装部Ｐ２１に嵌装させるといった簡単な方法で行うことができる。しかも、組み立てた状態では、各嵌装部Ｐ２１、Ｐ２２は、異なる方向に向けて開成している上、第４ロッド部Ｒ４と第５ロッド部Ｒ５とは互いに屈曲する関係にあるので、ロッドＲと連動部材Ｐとを単に引っ張るだけでは外れることはない。 As described above, in the member connection structure Y according to the present embodiment, after assembling the rod R and the interlocking member P, the fifth rod portion R5 is exposed from the insertion portion P2a to the second fitting portion P22 side. The fifth rod portion R5 can be fitted to the second fitting portion P22, and at least a part of the fourth rod portion R4 can be fitted to the first fitting portion P21. Moreover, in the assembled state, the fitting portions P21 and P22 are opened in different directions, and the fourth rod portion R4 and the fifth rod portion R5 are in a relationship of bending with each other. And simply pulling the interlocking member P does not come off.

すなわち、組付けが簡単で且つ組付け時の高い組付け強度を無理なく確保可能な優れた部材の接続構造Ｙを提供することができる。 That is, it is possible to provide an excellent member connection structure Y that is easy to assemble and can ensure a high assembling strength without difficulty.

なお、前記第５ロッド部Ｒ５を前記第２の嵌装部Ｐ２２側に位置付けた状態で、前記第４ロッド部Ｒ４をその長手方向と直交する方向に回動させることにより、前記第５ロッド部Ｒ５を、前記第２の嵌装部Ｐ２２に嵌装させるようにしているため、ロッドＲと連動部材Ｐとの組立を、第５ロッド部Ｒ５を挿通部Ｐ２ａから第２の嵌装部Ｐ２２側に露出させた後、捻って止めるといった非常に簡単な方法で行うことができる。 In addition, by rotating the fourth rod portion R4 in a direction orthogonal to the longitudinal direction in a state where the fifth rod portion R5 is positioned on the second fitting portion P22 side, the fifth rod portion Since R5 is fitted to the second fitting part P22, the assembly of the rod R and the interlocking member P is performed on the fifth rod part R5 from the insertion part P2a to the second fitting part P22 side. It can be performed by a very simple method such as twisting and stopping after being exposed to.

前記第１の方向と前記第２の方向とが、略１８０度反転する関係にあるものとしているため、連動部材Ｐの成形用金型を無用に複雑化する必要がなくコストダウンを図ることができる。 Since the first direction and the second direction are in a relationship of reversing approximately 180 degrees, it is not necessary to make the molding die for the interlocking member P unnecessarily complicated, and cost reduction can be achieved. it can.

前記第１の嵌装部Ｐ２１及び前記第２の嵌装部Ｐ２２が、前記ロッドＲの直径と略一致する幅寸法を有する溝状のものとしているため、特別な締結部材を用いることなく、ロッドＲと連動部材Ｐとを好適に組付けることができる。 Since the first fitting portion P21 and the second fitting portion P22 have a groove shape having a width dimension substantially matching the diameter of the rod R, the rod can be used without using a special fastening member. R and the interlocking member P can be assembled | attached suitably.
