It concerns on the raising / lowering shelf apparatus of any one of these.

また、前記付勢手段取付部８は、長さのある断面Ｕ字形若しくは断面コ字形の板材で構成すると共に、この付勢手段取付部８をその両側の突出板部８Ａが前記基体２から垂下するようにして基体２に付設し、この付勢手段取付部８の基端部の各突出板部８Ａ間に前記付勢手段５の一側端部を連結する連結部９を設け、この付勢手段取付部８の先端部の各突出板部８Ａを下方へ延設して垂下部10を形成すると共に、この各垂下部10に夫々前記連動軸６の略中間部の左右位置を回動自在に支承する前記補強用支承部７を設けたことを特徴とする請求項２〜４のいずれか１項に記載の昇降棚装置に係るものである。 The biasing means mounting portion 8 is formed of a long U-shaped or U-shaped cross-sectional plate material, and the biasing means mounting portion 8 is suspended from the base 2 by protruding plate portions 8A on both sides thereof. In this manner, the connecting portion 9 is provided between the projecting plate portions 8A at the base end portion of the biasing means mounting portion 8 to connect one end portion of the biasing means 5 to the base body 2, Each projecting plate portion 8A at the tip of the biasing means mounting portion 8 is extended downward to form a hanging portion 10, and the left and right positions of the substantially intermediate portion of the interlocking shaft 6 are rotated to each hanging portion 10 respectively. The lifting support device according to any one of claims 2 to 4, characterized in that the reinforcing support portion (7) for supporting freely is provided.

本発明は上述のように構成したから、連動軸の略中間位置に連結する一つの付勢手段によって昇降棚体の付勢保持機能を賄うことが可能となるため、左右のアーム夫々に別々の付勢手段によって付勢力を付与する前記特許文献１のような従来構造に比して、付勢手段５の数量が少なくて済む分コストダウン化が図れることになり、また、付勢手段を左右の各支持腕体間に架設した連動軸の略中間位置に連結したため、この付勢手段の付勢力が左右の各支持腕体の双方に略均等に伝達されてこの左右の支持腕体を介した昇降棚体のスムーズな昇降作動が得られることになり、しかも、本発明では連動軸の略中間部には付勢手段による付勢力が常に作用するが、この付勢手段の付勢方向に連動軸が変形しようとすることを補強用支承部が阻止するので、連動軸が簡単に変形するようなことなく従来品と同等の耐久性を発揮し得るなど、極めて実用性に秀れた画期的な昇降棚装置となる。 Since the present invention is configured as described above, it is possible to cover the urging / holding function of the elevating shelf by one urging means connected to the substantially intermediate position of the interlocking shaft. Compared to the conventional structure such as Patent Document 1 in which the urging force is applied by the urging means, the number of the urging means 5 can be reduced, and the cost can be reduced. Since the linking force is transmitted to the left and right support arm bodies through the left and right support arm bodies. In addition, in the present invention, the urging force by the urging means always acts on the substantially intermediate portion of the interlocking shaft in the urging direction of the urging means. Reinforcing support block prevents the interlocking shaft from deforming In and interlocking shaft can exhibit a conventional equivalent durability without such deform easily, an extremely innovative lifting shelf apparatus Xiu been practical.

また、請求項２記載の発明においては、付勢手段が連動軸に付勢力を付与して昇降棚体を収納状態と引き降ろし状態とに付勢保持する構成を簡易に設計実現可能となり、しかも、付勢手段を基体に連結するための付勢手段取付部と連動軸を支承する補強用支承部とを一部品で構成することも可能となるので、一層のコストダウン化を実現可能となるなど、極めて実用性に秀れた構成の昇降棚装置となる。 Further, in the invention of claim 2, it is possible to easily design and realize a configuration in which the biasing means applies a biasing force to the interlocking shaft and biases and holds the lifting shelf in the stored state and the pulled-down state, The urging means mounting portion for connecting the urging means to the base and the reinforcing support portion for supporting the interlocking shaft can be configured as one part, so that further cost reduction can be realized. Thus, the elevator shelf apparatus is extremely practical.

また、請求項３記載の発明においては、前記請求項２記載の発明の作用・効果を確実に発揮する付勢手段取付部を簡易に設計実現可能となる一層実用性に秀れた構成の昇降棚装置となる。 Further, in the invention described in claim 3, it is possible to easily design and implement an urging means mounting portion that reliably exhibits the operation and effect of the invention described in claim 2, and to further increase and decrease the practicality.

The structure is not complicated because it is only necessary to form the support part in the minimum shape to support only the structure, and because it is made of a plate material with excellent workability, this support part can be easily designed This makes it possible to provide an elevating shelf device having a configuration that is more practical.

また、請求項５記載の発明においては、付勢手段取付部を加工性に秀れた板材で構成するため、付勢手段取付部に連結部と補強用支承部を容易に一体成形可能であり、しかも、板材を断面Ｕ字状若しくは断面コ字状に折曲形成して成るこの補強用台座部は強度が高いため、前記付勢手段を強固に連結できると共に、連動軸を補強用支承部が高い支承強度をもって支承でき、その上、連動軸の中間部近傍の左右二箇所を補強用支承部が支承するため、連動軸に対して一層良好な補強作用を付与できることとなるなど、極めて実用性に秀れた構成の昇降棚装置となる。 Further, in the invention described in claim 5, since the biasing means mounting portion is made of a plate material excellent in workability, the connecting portion and the reinforcing support portion can be easily integrally formed with the biasing means mounting portion. In addition, since the reinforcing pedestal portion formed by bending the plate material into a U-shaped section or a U-shaped cross section has high strength, the urging means can be firmly connected and the interlocking shaft can be connected to the reinforcing support portion. Can be supported with high bearing strength, and in addition, since the reinforcing bearings support the left and right locations near the middle of the interlocking shaft, it is possible to give a better reinforcing action to the interlocking shaft. It becomes an elevating shelf device having a configuration excellent in properties.

好適と考える本発明の実施形態（発明をどのように実施するか）を、図面に基づいて本発明の作用を示して簡単に説明する。 Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

本昇降棚装置の基体２を、室内の天井面や各種棚設備Ｔの下面などの取付面部１に取付固定すると、基体２の左右両側部に枢着した各支持腕体３の回動により各支持腕体３の先端部に枢着した前記昇降棚体４を取付面部１に沿設した収納状態から下方へ下がった位置に引き降ろし配設することができ、また、引き降ろし配設した昇降棚体４を各支持腕体３の逆回動により上昇させて取付面部１に沿設した収納状態とすることができる。 When the base body 2 of the lifting / lowering shelf apparatus is attached and fixed to the mounting surface portion 1 such as the ceiling surface of the room or the bottom surface of the various shelf facilities T, each support arm body 3 pivotally attached to the left and right side portions of the base body 2 rotates. The lifting / lowering shelf 4 pivotally attached to the tip of the support arm 3 can be lowered and disposed at a position lowered downward from the stored state along the mounting surface 1, and the lifting / lowering shelf provided with lowering. 4 can be raised by reverse rotation of each support arm 3 to be in a storage state along the mounting surface 1.

また、本昇降棚装置は、付勢手段５により昇降棚体４が前記取付面部１に沿設した収納状態と、下方へ引き降ろし配設した状態とに付勢保持される。 Further, the lifting shelf apparatus is biased and held by the biasing means 5 in the stowed state where the lifting shelf body 4 is provided along the mounting surface portion 1 and in the state where the lifting shelf body 4 is pulled down.

本発明の付勢手段５は、左右の各支持腕体３間に架設した連動軸６の軸長さ方向の略中間部に連結し、この付勢手段５の付勢力が前記連動軸６と前記支持腕体３を介して前記昇降棚体４に伝達する構成としている。 The biasing means 5 of the present invention is connected to a substantially intermediate portion in the axial length direction of the interlocking shaft 6 installed between the left and right support arm bodies 3, and the biasing force of the biasing means 5 is coupled to the interlocking shaft 6. It is configured to transmit to the lifting shelf 4 via the support arm 3.

このように左右の各支持腕体３間に架設した連動軸６の略中間位置に付勢手段５を連結する構成にあっては、左右の支持腕体３の夫々に対して別々の付勢手段５を設けずとも、連動軸６の略中間位置に連結する一つの付勢手段５によって前記昇降棚体４の付勢保持機能を賄うことが可能となる。 In the configuration in which the urging means 5 is connected to the substantially intermediate position of the interlocking shaft 6 installed between the left and right support arm bodies 3 as described above, separate urging forces are applied to each of the left and right support arm bodies 3. Even if the means 5 is not provided, the urging / holding function of the elevating shelf 4 can be provided by one urging means 5 connected to a substantially intermediate position of the interlocking shaft 6.

しかも、付勢手段５を左右の各支持腕体３間に架設した連動軸６の略中間位置に連結したことにより、この付勢手段５の付勢力が左右の各支持腕体３の双方に確実に略均等に伝達されることになるので、左右の支持腕体３の回動作動がスムーズに行われて、昇降棚体４のスムーズな昇降作動が実現することになる。 In addition, since the biasing means 5 is connected to a substantially intermediate position of the interlocking shaft 6 installed between the left and right support arm bodies 3, the biasing force of the biasing means 5 is applied to both the left and right support arm bodies 3. As a result, the left and right support arm bodies 3 are smoothly rotated, and the lifting and lowering rack body 4 is smoothly lifted and lowered.

従って、本発明においては、付勢手段５が一つで足りる構成が実現可能であるから、左右のアーム夫々に別々の付勢手段によって付勢力を付与する前記特許文献１のような従来構造に比して、付勢手段５の数量が少なくて済む分コストダウン化が図れ、安価な製品を提供可能となる。 Therefore, in the present invention, a configuration in which only one urging means 5 is sufficient is feasible, so that the conventional structure such as Patent Document 1 in which the urging force is applied to the left and right arms by separate urging means is provided. In comparison, the amount of the biasing means 5 can be reduced, so that the cost can be reduced and an inexpensive product can be provided.

一方、本発明は、付勢手段５を連動軸６の略中間位置に連結したことにより、この連動軸６の略中間部には付勢手段５による付勢力が常に作用するので、この付勢手段５の付勢方向に連動軸６が変形してしまう懸念がある。 On the other hand, in the present invention, since the urging means 5 is connected to the substantially intermediate position of the interlocking shaft 6, the urging force of the urging means 5 always acts on the substantially intermediate portion of the interlocking shaft 6. There is a concern that the interlocking shaft 6 may be deformed in the urging direction of the means 5.

しかし、本発明では、この付勢手段５と連結した連動軸６の略中間部の近傍位置を補強用支承部７が回動自在に支承して、この付勢手段５による付勢方向に連動軸６が変形しようとすることを阻止することになる。 However, in the present invention, the reinforcing support portion 7 is rotatably supported in the vicinity of the substantially intermediate portion of the interlocking shaft 6 connected to the biasing means 5 and interlocks with the biasing direction by the biasing means 5. This will prevent the shaft 6 from being deformed.

従って、連動軸６が付勢手段５の付勢力によって簡単に変形するようなことがなく、従来構造品と同等の耐久性能を発揮する。 Therefore, the interlocking shaft 6 is not easily deformed by the urging force of the urging means 5 and exhibits the durability performance equivalent to that of the conventional structure product.

尚、連動軸６を、強度の高い素材で構成したり径の太いもので構成したりして、連動軸６自身の強度を高めることによっても変形防止作用は得られるが、強度の高い軸材は非常に高価であるため、本発明のように連動軸６を別の部品（補強用支承部７）で支承して補強する構成の方が、コストをかけずに安価に設計実現可能であることが確認されている。 Although the interlocking shaft 6 can be made of a high-strength material or a material having a large diameter to increase the strength of the interlocking shaft 6 itself, the deformation preventing effect can be obtained. Is very expensive, and the configuration in which the interlocking shaft 6 is supported and reinforced by another part (reinforcing support portion 7) as in the present invention can be realized at low cost without cost. It has been confirmed.

従って、この補強用支承部７による連動軸６の補強構造も、コスト安に設計実現可能である。 Therefore, the reinforcing structure of the interlocking shaft 6 by the reinforcing support portion 7 can also be designed at a low cost.

本発明の具体的な実施例について図面に基づいて説明する。 Specific embodiments of the present invention will be described with reference to the drawings.

本実施例の昇降棚装置は、図１に示すように、室内の天井面や各種棚設備Ｔの下面などの取付面部１に取付固定可能な基体２の左右両側部に支持腕体３を枢着し、この左右夫々の支持腕体３の先端部に昇降棚体４を枢着して、各支持腕体３の回動によりこの昇降棚体４を取付面部１に沿設した収納状態から下方へ下がった位置に引き降ろし配設することができるようにしている。尚、図面では、棚設備Ｔとしてキッチンの吊戸棚Ｔ１を採用し、この吊戸棚Ｔ１の下面を取付面部１として基体２を取付固定した場合を示している。 As shown in FIG. 1, the lifting shelf apparatus of the present embodiment pivots support arms 3 on both left and right sides of a base 2 that can be fixedly attached to a mounting surface 1 such as an indoor ceiling surface or the lower surface of various shelf facilities T.

また、この基体２の左右に存する前記各取付枠材21には、この基体２を前記取付面部１へ取付固定するために用いる釘やネジなどの止着具15挿通用の挿通孔14を複数設けると共に、各取付枠材21の夫々の外側部分を略直角に下方へ折曲して、この各折曲垂下板部21Ａの前側部（図１における左側部）に夫々前後一対の帯板状の前記支持腕体３の基端部を枢着した構成としている。 Each mounting frame member 21 on the left and right sides of the base 2 has a plurality of insertion holes 14 for inserting fasteners 15 such as nails and screws used to fix the base 2 to the mounting surface 1. And a pair of front and rear strips on the front side portion (left side portion in FIG. 1) of each bent hanging plate portion 21A. The support arm body 3 has a base end portion pivotally attached thereto.

本実施例の昇降棚体４は、前記基体２に対して、前後幅と左右幅とが略合致するか又は前後幅と左右幅とがやや小さい幅寸法を有する横長形状であって且つやや厚みのある方形板状体に構成している。 The elevating shelf 4 of the present embodiment is a horizontally long shape with a slightly smaller width dimension with respect to the base body 2 such that the front-rear width and the left-right width substantially match or the front-rear width and the left-right width are slightly smaller. It has a rectangular plate-like body.

そして、この昇降棚体４の左右側部の夫々の後側部に、前記前後の各支持腕体３の先端部を枢着すると共に、前後の各支持腕体３で平行リンク機構を構成し、これにより前記基体２を前記取付面部１に取付固定すると、図４，図５に示すように、各支持腕体３の回動により昇降棚体４が基体２（取付面部１）に対し略平行関係を維持したまま（昇降棚体４が略水平状態を維持したまま）下方へ引き降ろしでき、また不使用時には、各支持腕体３の回動により左右の取付枠体21間（左右の垂下板部21Ａ間）に昇降棚体４を配して取付面部１に沿設した折り畳み収納状態にできる構成としている。 And the front-end | tip part of each said support arm body 3 is pivotally attached to each rear side part of the right-and-left side part of this raising / lowering shelf 4, and a parallel link mechanism is comprised with each support arm body 3 before and behind. Thus, when the base 2 is attached and fixed to the mounting surface 1, as shown in FIGS. 4 and 5, the elevating shelf 4 is substantially moved with respect to the base 2 (mounting surface 1) by the rotation of each support arm 3. It can be pulled down while maintaining the parallel relationship (while the elevating shelf 4 is maintained in a substantially horizontal state), and when not in use, the support arm body 3 is rotated between the left and right mounting frames 21 (left and right hanging) The elevating shelf 4 is arranged between the plate portions 21 </ b> A) so that it can be folded and stored along the mounting surface portion 1.

また、本実施例は、この昇降棚体４を前記取付面部１に沿設した収納状態と下方へ引き降ろし配設した状態とに付勢保持する付勢手段５を備えている。 Further, the present embodiment includes a biasing means 5 that biases and holds the lifting shelf 4 in a stored state along the mounting surface portion 1 and a state in which it is lowered and disposed.

具体的には、本実施例の付勢手段５は、伸縮可能なピストン・シリンダ構造であって、常に伸長しようとする方向に付勢力を生じるガススプリング５を採用している。 Specifically, the urging means 5 of the present embodiment has a piston / cylinder structure that can be expanded and contracted, and employs a gas spring 5 that always generates an urging force in a direction to extend.

また、前記基体２の左右方向の略中間部に付勢手段取付部８を設け、この付勢手段取付部８の基端部に、前記付勢手段５たるガススプリング５の伸縮方向の一側端部（シリンダ側の端部）を枢着連結した構成としている。 Further, an urging means mounting portion 8 is provided at a substantially intermediate portion in the left-right direction of the base body 2, and one side of the gas spring 5 serving as the urging means 5 in the expansion / contraction direction is provided at the base end of the urging means mounting portion 8. The end portion (end portion on the cylinder side) is pivotally connected.

また、前記四体の各支持腕体３のうち、前記基体２の前側に位置する左右の各支持腕体３間に、この各支持腕体３の回動に連動して回動する連動軸６を架設している。更に詳しくは、前側左右の各支持腕体３の、前記基体２の取付枠材21との枢着軸と同一軸線上（同一軸線位置）に丸棒状の連動軸６を架設固定している。 Further, among the four support arm bodies 3, an interlocking shaft that rotates between the left and right support arm bodies 3 positioned on the front side of the base body 2 in conjunction with the rotation of the support arm bodies 3. 6 is installed. More specifically, a round bar-like interlocking shaft 6 is installed and fixed on the same axis line (same axis position) as the pivot shaft of the support arms 3 on the front left and right with the mounting frame member 21 of the base 2.

また、図６に示すようにこの連動軸６の軸長さ方向の中間部に、この連動軸６の軸長さ方向と直交する方向に向けて板状の連結片部11を突設してこの連結片部11が連動軸６と共に回動する構成とし、この連結片部11の突出先端部に前記付勢手段５たるガススプリング５の伸縮方向の他側端部（ピストン側の端部）を枢着連結した構成としている。 Further, as shown in FIG. 6, a plate-like connecting piece portion 11 is projected from the intermediate portion in the axial length direction of the interlocking shaft 6 in a direction orthogonal to the axial length direction of the interlocking shaft 6. The connecting piece portion 11 is configured to rotate together with the interlocking shaft 6, and the other end portion (end portion on the piston side) in the expansion / contraction direction of the gas spring 5 serving as the biasing means 5 is provided at the projecting tip portion of the connecting piece portion 11. Is configured to be pivotally connected.

従って、ガススプリング５が連動軸６と直交する方向に配されてこの連動軸６を連動軸６の軸長さ方向と略直交する方向に押動付勢することになり、このガススプリング５の付勢力により連動軸６に回転力が付与されて、前記支持腕体３を介して前記昇降棚体４に伝達する構成としている。 Therefore, the gas spring 5 is arranged in a direction orthogonal to the interlocking shaft 6 and pushes and urges the interlocking shaft 6 in a direction substantially orthogonal to the axial length direction of the interlocking shaft 6. A rotational force is applied to the interlocking shaft 6 by an urging force, and is transmitted to the lifting shelf 4 via the support arm 3.

更に詳しくは、昇降棚体４が前記取付面部１に沿設した収納状態においては、図４に示すように連結片部11とガススプリング５との枢着軸部12が前記連動軸６よりも上方に位置することで連動軸６には前回り方向への回転付勢力が作用し、これにより各支持腕体３が図面の後方（上方）へ回動しようとしてこの昇降棚体４が取付面部１に沿設した収納状態が付勢保持され、一方、昇降棚体４が下方へ最大限引き降ろされた状態においては、図５に示すように連結片部11とガススプリング５との枢着軸部12が前記連動軸６と略同等の高さ又は連動軸６よりもやや下方に位置することで連動軸６には後回り方向への回転付勢力が作用し、これにより各支持腕体３が図面の前方（下方）へ回動しようとしてこの昇降棚体４が下方へ引き降ろし配設した状態が付勢保持される構成としている。 More specifically, in the stowed state in which the elevating shelf 4 is provided along the mounting surface 1, the pivot shaft 12 of the connecting piece 11 and the gas spring 5 is more than the interlocking shaft 6 as shown in FIG. By being positioned at the upper side, a forward urging force acts on the interlocking shaft 6 so that each of the supporting arm bodies 3 tries to rotate backward (upward) in the drawing so that the lifting shelf 4 is attached to the mounting surface portion. In the state in which the stowed state along 1 is biased and held, while the elevating shelf 4 is pulled down to the maximum extent, the connecting piece 11 and the gas spring 5 are pivotally attached as shown in FIG. Since the shaft portion 12 is located at a height substantially equal to the interlocking shaft 6 or slightly below the interlocking shaft 6, a rotational urging force in the backward direction acts on the interlocking shaft 6. This lifting / lowering shelf 4 is arranged to be lowered downward in order to rotate 3 forward (downward) in the drawing. State is configured to be biased held.

本実施例では、この付勢手段５と連結した連動軸６の略中間部の近傍位置を回動自在に支承して、この付勢手段５による付勢方向に連動軸６が変形しようとすることを阻止する補強用支承部７を備えている。 In this embodiment, a position in the vicinity of a substantially intermediate portion of the interlocking shaft 6 connected to the biasing means 5 is rotatably supported, and the interlocking shaft 6 tends to deform in the biasing direction by the biasing means 5. A reinforcing support 7 is provided to prevent this.

即ち、本実施例の構成では、付勢手段５が前記連動軸６をこの連動軸６の軸長さ方向と略直交する方向に常に押動付勢するため、連動軸６にはこの付勢手段５の付勢方向に変形しようとする力が作用するが、この連動軸６の変形を補強用支承部７によって防止する構成としている。 That is, in the configuration of the present embodiment, the biasing means 5 always pushes and biases the interlocking shaft 6 in a direction substantially orthogonal to the axial length direction of the interlocking shaft 6. A force for deforming in the urging direction of the means 5 acts, but the deformation of the interlocking shaft 6 is prevented by the reinforcing support portion 7.

具体的には、本実施例の補強用支承部７は、前記基体２に設けた前記付勢手段取付部８の先端部に設けている。 Specifically, the reinforcing support portion 7 of the present embodiment is provided at the distal end portion of the biasing means mounting portion 8 provided on the base 2.

ここで、本実施例の付勢手段取付部８について具体的に説明すると、図２，図３，図７，図８に示すように、前記取付枠材21の前後長さ寸法と略同等の長さ寸法を有し且つ断面略コ字形に屈曲形成した金属製板材で構成している。 Here, the urging means mounting portion 8 of this embodiment will be described in detail. As shown in FIGS. 2, 3, 7, and 8, the front and rear length dimensions of the mounting frame member 21 are substantially the same. It is made of a metal plate having a length dimension and bent to have a substantially U-shaped cross section.

この付勢手段取付部８は、その両側の突出板部８Ａを下向きとした上で、その基端部の中間板部８Ｂを前記基枠材20の略中間部の下面に重合固定して、この付勢手段取付部８が前記各取付枠材21と平行に且つ各取付枠材21と同方向へ突出状態となるように設け、この付勢手段取付部８の各突出板部８Ａが前記基体２から垂下する構成としている。図中符号16は基体２（基枠材20）と付勢手段取付部８（中間板部８Ｂ）とを固定するための固定具である。 The biasing means mounting portion 8 has the protruding plate portions 8A on both sides thereof facing downward, and the intermediate plate portion 8B of the base end portion is overlapped and fixed to the lower surface of the substantially intermediate portion of the base frame member 20, The urging means attaching portions 8 are provided so as to protrude in the same direction as the attaching frame members 21 in parallel with the attaching frame members 21, and the protruding plate portions 8 A of the urging means attaching portions 8 A structure depending on the base 2 is adopted. Reference numeral 16 in the figure denotes a fixing tool for fixing the base 2 (base frame member 20) and the urging means mounting portion 8 (intermediate plate portion 8B).

また、この付勢手段取付部８の基端部の各突出板部８Ａ間に取付軸13を架設して連結部９とし、この連結部９（取付軸13）に各突出板部８Ａ間に配した前記付勢手段５たるガススプリング５の一側端部（シリンダ側の端部）を枢着連結している。 Further, a mounting shaft 13 is installed between the protruding plate portions 8A at the base end of the biasing means mounting portion 8 to form a connecting portion 9, and the connecting portion 9 (mounting shaft 13) is connected between the protruding plate portions 8A. One side end portion (end portion on the cylinder side) of the gas spring 5 serving as the biasing means 5 is pivotally connected.

また、この付勢手段取付部８の先端部の各突出板部８Ａを下方へ延設して垂下部10を形成すると共に、この各垂下部10に夫々前記連動軸６の略中間部の左右位置を回動自在に支承する前記補強用支承部７を設けている。 Further, each projecting plate portion 8A at the tip of the urging means mounting portion 8 extends downward to form a hanging portion 10, and each hanging portion 10 has a left and right of a substantially intermediate portion of the interlocking shaft 6, respectively. The reinforcing support portion 7 for rotatably supporting the position is provided.

更に詳しくは、付勢手段取付部８を構成する板材を予めＴ形に形成しておき、この板材を断面コ字状に折曲形成することによって同時に先端部左右に各突出板部８Ａよりも下方へ垂下突出する垂下部10が一体に連設形成される構成としている。 More specifically, a plate material constituting the urging means mounting portion 8 is formed in a T shape in advance, and the plate material is bent into a U-shaped cross section so that the tip portion can be more horizontally moved than the protruding plate portions 8A. A hanging part 10 projecting downward is integrally formed continuously.

また、図７に示すように、この垂下部10の後側縁（基体２の後方側の側縁）に半円形の切欠部を形成すると共に、この切欠部に前記連動軸６の周面の半周ほどを回動自在に支承し得る略半円形の緩衝体７Ａを付設して前記補強用支承部７を構成している。 Further, as shown in FIG. 7, a semicircular cutout is formed at the rear edge of the drooping portion 10 (the side edge on the rear side of the base 2), and the peripheral surface of the interlocking shaft 6 is formed in the cutout. The reinforcing support portion 7 is configured by attaching a substantially semicircular cushioning body 7A that can be rotatably supported about a half circumference.

即ち、本実施例の補強用支承部７は、前記付勢手段５による押動付勢方向に抗する方向にだけ連動軸６を支承して補強する構成としている。尚、例えば、孔状の補強用支承部７を構成して連動軸６の全周を支承するようにしても良いが、本実施例のように、連動軸６の半周ほどであって前記付勢手段５による押動付勢方向に抗する方向だけを支承する構成の補強用支承部７によれば、これだけでも付勢手段５による付勢力に抗して連動軸６を確実に補強して変形阻止できる上、補強用支承部７が開放していることで、この補強用支承部７に対して連動軸６の脱着が簡単に可能となるため、連動軸６が架設固定された支持腕体３を基体２（取付枠材21）に対して容易に組み付け可能となり、量産性に秀れるなどの効果を奏することになるので好ましい。 That is, the reinforcing support portion 7 of this embodiment is configured to support and reinforce the interlocking shaft 6 only in the direction against the pressing biasing direction by the biasing means 5. For example, the hole-shaped reinforcing support portion 7 may be configured to support the entire circumference of the interlocking shaft 6, but as in the present embodiment, it is about the half circumference of the interlocking shaft 6, and is According to the reinforcing support portion 7 configured to support only the direction against the pushing bias direction by the biasing means 5, this alone can reliably reinforce the interlocking shaft 6 against the biasing force by the biasing means 5. In addition to being able to prevent deformation, since the reinforcing support 7 is open, the interlocking shaft 6 can be easily attached to and detached from the reinforcing support 7. It is preferable because the body 3 can be easily assembled to the base body 2 (mounting frame member 21), and effects such as excellent mass productivity can be obtained.

尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。 Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
