Description

本発明は、椅子等の家具の脚装置に係わり、更に詳しくは複数の椅子やテーブルあるいは長椅子、ベンチ等を支持することが可能な椅子等の家具の脚装置に関するものである。   The present invention relates to a leg device for furniture such as a chair, and more particularly to a leg device for furniture such as a chair capable of supporting a plurality of chairs, tables, chaise longues, benches and the like.

従来から、左右の脚体間に連結杆を水平に連結するとともに、該連結杆に座部と背凭れ部を支持した構造の椅子は各種提供されている。例えば、特許文献１には、脚体の上端部に内方へ四角形の連結突部を設け、左右両側に配した脚体の連結突部に角パイプからなる連結杆の両端部を嵌合して、重合部をネジで締結した構造の脚部が開示されている。そして、前記連結杆には左右一対の側面視略Ｌ字形の座席支持部材を連結し、該座席支持部材の座支持杆で座部を支持するとともに、上方へ立ち上がった背凭れ支持杆で背凭れ部を支持する構造の椅子が開示されている。   Conventionally, various types of chairs having a structure in which a connecting rod is horizontally connected between the left and right legs and a seat portion and a backrest portion are supported by the connecting rod are provided. For example, in Patent Document 1, a rectangular connecting protrusion is provided inwardly at the upper end of the leg, and both ends of a connecting rod made of a square pipe are fitted to the connecting protrusions of the leg disposed on the left and right sides. A leg portion having a structure in which the overlapping portion is fastened with screws is disclosed. Then, a pair of left and right side-view substantially L-shaped seat support members are connected to the connection rod, and the seat portion is supported by the seat support rod of the seat support member, and the backrest is supported by the backrest support rod rising upward. A chair having a structure for supporting a portion is disclosed.

また、特許文献２には、脚体の上端に設けた水平杆の上面に、前後に間隔を置いて嵌合溝を形成し、一対の丸パイプからなる支持杆を前後に延びたブラケットで平行に連結し、両支持杆を前記嵌合溝に嵌合した状態で、上方から挟持部材の下面に形成した嵌合溝を両支持杆に嵌合し、前記脚体の水平杆と挟持部材とを止めネジで締結することにより支持杆の端部を上下から挟持して支持した脚部の構造が開示されている。そして、座部と背凭れ部とが一体となった座板を前記ブラケットにネジ止めして支持した連結椅子が開示されている。   Further, in Patent Document 2, a fitting groove is formed on the upper surface of a horizontal rod provided at the upper end of a leg with a space in the front and rear, and a support rod made of a pair of round pipes is paralleled by a bracket extending in the front and rear directions. In the state where both support rods are fitted in the fitting grooves, the fitting grooves formed on the lower surface of the clamping member from above are fitted into the both support rods, and the horizontal rods of the legs and the clamping members The structure of the leg part which clamped and fixed the end part of the support rod from the upper and lower sides by fastening with a set screw is disclosed. A connecting chair is disclosed in which a seat plate in which a seat portion and a backrest portion are integrated is screwed to and supported by the bracket.

しかし、特許文献１の脚部の構造は、一方の連結杆の前面側に座席支持部材を連結して支持するので、荷重が前がかりになって連結杆に大きな捩れ応力が作用し、脚体と連結杆の連結部分に過大な力が加わり、耐久性において不安がある。一方、特許文献２の脚部の構造は、座部にかかる荷重を前後に間隔を置いて両脚体に連結した一対の支持杆で均等に受けるので、安定であるが、支持杆の端部が脚体の側方に露出するので外観性において見劣りがするばかりでなく、脚体の水平杆と挟持部材を締結している止めネジが緩んだ場合に、両部材の嵌合溝から支持杆が抜けることも予想される。
実開平６−６６３９３号公報 特許第３９５８５５９号公報 However, in the structure of the leg portion of Patent Document 1, the seat support member is connected and supported on the front side of one connecting rod, so that a large torsional stress acts on the connecting rod due to the load acting as a forehead. And excessive force is applied to the connecting part of the connecting rod, and there is concern about durability. On the other hand, the structure of the leg portion of Patent Document 2 is stable because the load applied to the seat portion is evenly received by a pair of support rods connected to both legs at an interval in the front-rear direction. Since it is exposed to the side of the leg, not only the appearance is inferior, but also when the set screw that fastens the horizontal hook of the leg and the clamping member is loosened, the support hook is inserted from the fitting groove of both members It is expected to come out.

そこで、本発明が前述の状況に鑑み、解決しようとするところは、複数の椅子やテーブルあるいは長椅子、ベンチ等を支持することが可能な椅子等の家具の脚装置において、左右両側に配した脚体間に連結杆の両端部を簡単且つ確実に連結でき、また外観性にも優れ、しかも連結ネジが緩んでも脚体と連結杆とが外れることがない椅子等の家具の脚装置を提供する点にある。   Accordingly, in view of the above-described situation, the present invention intends to solve the problem in that the legs arranged on the left and right sides of a furniture leg device such as a chair that can support a plurality of chairs, tables, chaise longues, benches, etc. Provided is a leg device for a furniture such as a chair that can easily and surely connect both ends of a connecting rod between bodies, has excellent appearance, and does not come off the leg and connecting rod even if the connecting screw is loosened. In the point.

本発明は、前述の課題解決のために、左右両側に配した脚体間に水平な連結杆の両端部を連結し、該連結杆で椅子の座部等を支持してなる椅子等の家具の脚装置であって、逆Ｕ字形の脚体の上部に設けた取付部に横長の凹部を形成し、連結杆の端部を前記凹部に嵌合するとともに、外側から該凹部を貫通したボルトを前記連結杆の端部に螺合したことを特徴とする椅子等の家具の脚装置を構成した（請求項１）。   In order to solve the above-mentioned problem, the present invention is a furniture such as a chair, in which both ends of a horizontal connecting rod are connected between legs arranged on the left and right sides, and a seat portion of the chair is supported by the connecting rod. A leg device having a horizontally long recess formed in an upper portion of an inverted U-shaped leg, and fitting an end of a connecting rod into the recess and penetrating the recess from the outside. A leg device for furniture such as a chair or the like is characterized in that is screwed to the end of the connecting rod (claim 1).

ここで、前記連結杆を丸パイプで形成し、前後一対設けてなることが好ましい（請求項２）。   Here, it is preferable that the connecting rod is formed of a round pipe, and a pair of front and rear are provided.

ここで、前記脚体の左右両面に前記取付部を対称に形成し、該取付部に長円形状の凹部を形成し、該凹部に丸パイプからなる前記連結杆の端部を嵌合するとともに、前記凹部の底面板で各連結杆の中心に対応する位置に取付孔を穿設し、外側から前記取付孔に挿通したボルトを、前記連結杆の端部の内部に固着した固定板に螺合してなることがより好ましい（請求項３）。   Here, the mounting portions are formed symmetrically on both the left and right sides of the leg, an oval recess is formed in the mounting portion, and the end of the connecting rod made of a round pipe is fitted into the recess. A mounting hole is formed at a position corresponding to the center of each connecting rod in the bottom plate of the concave portion, and a bolt inserted into the mounting hole from the outside is screwed to a fixing plate fixed inside the end portion of the connecting rod. It is more preferable that they are combined (claim 3).

更に、一対の連結杆を前後に間隙を設けて配するとともに、両連結杆の上面に渡って複数の連結部材を固定して一体化してなることも好ましい（請求項４）。   Further, it is also preferable that the pair of connecting rods are arranged with a gap in the front and rear, and a plurality of connecting members are fixed and integrated over the upper surfaces of both connecting rods.

更に、前記脚体の外側の取付部にキャップを取付け、該キャップの裏面で前記ボルトの頭部を当止してなることがより好ましい（請求項５）。   Furthermore, it is more preferable that a cap is attached to the outer mounting portion of the leg, and the head of the bolt is stopped at the back surface of the cap.

以上にしてなる請求項１に係る発明の椅子等の家具の脚装置は、逆Ｕ字形の脚体の上部に設けた取付部に横長の凹部を形成し、連結杆の端部を前記凹部に嵌合するとともに、外側から該凹部を貫通したボルトを前記連結杆の端部に螺合したので、連結杆の端部を脚体の取付部に連結する際に、凹部に連結杆の端部を嵌合して仮止めができるので、施工がし易くなるとともに、連結杆の端部が隠れるので外観性に優れる。   In the leg device for furniture such as a chair according to the first aspect of the present invention, a horizontally long recess is formed in the mounting portion provided on the upper portion of the inverted U-shaped leg, and the end of the connecting rod is formed in the recess. Since the bolt that has been fitted and penetrated the concave portion from the outside is screwed into the end portion of the connecting rod, the end portion of the connecting rod is connected to the concave portion when the end portion of the connecting rod is connected to the mounting portion of the leg. Since it can be temporarily fixed by fitting, the construction is easy and the end of the connecting rod is hidden so that the appearance is excellent.

請求項２によれば、前記連結杆を丸パイプで形成し、前後一対設けてなることにより、直径の小さな連結杆を用いることができるので、コスト低減化に寄与し、また前後一対設けることにより捩れに対しても強度が高くなり、支持が安定する。   According to claim 2, since the connecting rods are formed of a round pipe and are provided with a pair of front and rear, it is possible to use connecting rods having a small diameter, which contributes to cost reduction and by providing a pair of front and rear. The strength is increased against twisting, and the support is stabilized.

請求項３によれば、脚体の左右両面に取付部を対称に形成したので、左右の脚体を同一のものを用いることができ、部品点数を少なくでき、また取付部に長円形状の凹部を形成し、該凹部に丸パイプからなる連結杆の端部を嵌合するとともに、前記凹部の底面板で各連結杆の中心に対応する位置に取付孔を穿設し、外側から前記取付孔に挿通したボルトを、前記連結杆の端部の内部に固着した固定板に螺合したので、前後一対の連結杆で椅子等の座部を支持した場合にも支持強度が高く、連結杆にかかる荷重は凹部との嵌合部を介して直接脚体で受けるので、脚体と連結杆との連結に供したボルトには力がかからないので、耐久性にも優れている。   According to the third aspect, since the attachment portions are formed symmetrically on the left and right sides of the leg body, the same left and right leg bodies can be used, the number of parts can be reduced, and the attachment portion has an oval shape. A recess is formed, and an end of a connecting rod made of a round pipe is fitted into the recess, and a mounting hole is formed at a position corresponding to the center of each connecting rod on the bottom plate of the recess, and the mounting is performed from the outside. Since the bolt inserted through the hole is screwed into the fixing plate fixed inside the end of the connecting rod, the support strength is high even when the seat portion such as a chair is supported by a pair of front and rear connecting rods. Since the load applied to is directly received by the leg through the fitting portion with the concave portion, no force is applied to the bolt used for the connection between the leg and the connecting rod, so that the durability is also excellent.

請求項４によれば、一対の連結杆を前後に間隙を設けて配するとともに、両連結杆の上面に渡って複数の連結部材を固定して一体化してなるので、両連結杆の上部に椅子の座部等を取付けて支持した場合でも、各連結杆には捩り応力が作用せず、曲げ応力だけが作用するので、連結杆の中心でボルトによって軸方向に締結する構造でもボルトが緩むことがないのである。   According to the fourth aspect of the present invention, the pair of connecting rods are arranged with a gap in the front and rear, and a plurality of connecting members are fixed and integrated over the upper surfaces of the two connecting rods. Even when a chair seat or the like is attached and supported, the torsional stress does not act on each connecting rod, but only the bending stress acts, so the bolt loosens even in the structure that is axially fastened by the bolt at the center of the connecting rod. There is nothing.

請求項５によれば、脚体の外側の取付部にキャップを取付け、該キャップの裏面でボルトの頭部を当止することにより、仮にボルトが緩んでもその頭部がキャップに当接してそれ以上の回転を阻止するので、ボルトが連結杆の端部から完全に外れることはないのである。   According to the fifth aspect, the cap is attached to the mounting portion on the outside of the leg, and the head of the bolt is abutted on the back surface of the cap, so that even if the bolt is loosened, the head abuts against the cap. Since the above rotation is prevented, the bolt is not completely detached from the end of the connecting rod.
