Description

本考案は、テーブルの高さ調整を行う継ぎ脚構造に関するものである。   The present invention relates to a joint leg structure for adjusting the height of a table.

テーブル等の高低大きく調整する場合には、テーブル等に装着されている主脚に継ぎ脚を継ぎ足すことで調整される。多用されている継ぎ脚はパイプ脚を採用した場合には、差込連結構造が採用されており、床面等と当接する脚座も主脚及び継ぎ脚の下端への差込装着構造が採用されている。また脚座による高さの微調整を行う構造として、脚座を脚端に螺合装着する構造が知られており、当該螺合構造を主脚の脚端に装着する場合は、継ぎ脚と主脚の着脱構造にも螺合構造が採用されている(特許文献1,2)。   When adjusting the height of a table or the like, it is adjusted by adding a joint leg to a main leg mounted on the table or the like. When pipe legs are used for the joint legs that are frequently used, an insertion connection structure is adopted, and the leg seats that come into contact with the floor surface etc. also adopt an insertion mounting structure to the lower ends of the main legs and joint legs Has been. As a structure for finely adjusting the height by the leg seat, a structure in which the leg seat is screwed to the leg end is known, and when the screwed structure is to be fitted to the leg end of the main leg, A screwing structure is also adopted for the main leg attachment / detachment structure (Patent Documents 1 and 2).

特許文献1,2に示された螺合連結構造は高さの微調整が可能であるが、継ぎ脚の連結着脱操作が煩瑣である。これに対して差込連結構造を採用すると連結操作が容易であるが高さの微調整ができない。また差込連結構造の主脚及び継ぎ脚の各脚端に脚座の螺合装着構造を採用することも可能であるが、差込連結構造を採用した場合には何らかの抜け止め構造を備えることが多く、この抜け止め構造には、差込側の外周面にバネ部材を突出させて設けている。このため仮に主脚及び継ぎ脚の各脚端の内周面に脚座の螺合のための螺条面を形成したとしても、継ぎ脚の抜き際に際してこの螺条周面を痛めてしまうことになる。   Although the screw connection structure shown in Patent Documents 1 and 2 can be finely adjusted in height, the connecting and detaching operation of the joint leg is troublesome. On the other hand, when the insertion connection structure is adopted, the connection operation is easy, but the height cannot be finely adjusted. In addition, it is possible to adopt a screw mounting structure of the leg seat at each leg end of the main and joint legs of the plug-in connection structure, but if a plug-in connection structure is adopted, it must have some kind of retaining structure. In many cases, this retaining structure is provided with a spring member protruding from the outer peripheral surface on the insertion side. For this reason, even if a thread surface for screwing the leg seat is formed on the inner peripheral surface of each leg end of the main leg and joint leg, this thread peripheral surface may be damaged when the joint leg is removed. become.

そこで本考案は、主脚と継ぎ脚に差込構造を採用すると共に、脚座の螺合装着を実現する新規なテーブル等の継ぎ脚構造を提案したものである。   In view of this, the present invention proposes a joint leg structure such as a new table that employs an insertion structure for the main leg and the joint leg, and realizes screwing of the leg seat.

本考案の請求項1記載に係るテーブル等の継ぎ脚構造は、脚下端に螺合装着する脚座を備え、差込連結して継ぎ足しするパイプ脚の継ぎ脚構造において、細径の差込挿入部にバネ線材を脚軸方向に突出させた抜け止め用の抵抗突部を設け、差込挿入部を受け入れる脚端部に、前記脚座を螺合装着する内周面螺条を備えると共に、前記内周面螺条に抵抗突部の通過溝を形成した脚座装着部を設けてなることを特徴とするものである。   The joint leg structure of a table or the like according to claim 1 of the present invention is a pipe leg joint structure that includes a leg seat that is threadedly attached to the lower end of the leg, and is inserted and connected to add a small diameter. A resistance protrusion for preventing the spring wire from protruding in the leg axis direction is provided on the portion, and an end surface of the leg that receives the insertion insertion portion is provided with an inner peripheral surface thread for screwing and mounting the leg seat, The inner peripheral surface thread is provided with a leg seat mounting portion in which a passage groove for a resistance protrusion is formed.

而して継ぎ脚の上端の細径の差込挿入部を、主脚(差込み受入れ側の脚)に差込挿着する際に、抵抗突部を通過溝に添わせて挿入することで脚座装着部の内周面螺条を痛めることなく差込連結がなされる。また継ぎ脚を連結しない場合には、脚座を螺合装着することができる。   Thus, when inserting and inserting the small diameter insertion insertion part at the upper end of the joint leg into the main leg (leg on the insertion receiving side), the leg is inserted by inserting the resistance protrusion along the passage groove. The insertion connection is made without damaging the inner peripheral surface thread of the seat mounting portion. When the joint leg is not connected, the leg seat can be screwed.

また本考案の請求項2に係るテーブル等の継ぎ脚構造は、脚座装着部が筒状樹脂材で形成され、脚端部に上端部分を外嵌合して設けると共に、通過溝を奥方の溝深さが浅くなる傾斜面に形成してなるもので、差込挿入部の挿入操作時に抵抗突部に対する当接を柔らかくすると共に、抵抗突部の抵抗感を少なくし、且つ抵抗突部の摩耗を減少させる。   Further, in the joint leg structure of the table or the like according to claim 2 of the present invention, the leg seat mounting part is formed of a cylindrical resin material, and the leg end part is provided with the upper end portion fitted outside, and the passage groove is provided at the back. It is formed on an inclined surface where the groove depth becomes shallower, softens the contact with the resistance protrusion during insertion operation of the insertion insertion part, reduces the resistance of the resistance protrusion, and reduces the resistance protrusion Reduce wear.

また本考案の請求項3に係るテーブル等の継ぎ脚構造は、特に脚下端(継ぎ脚)の脚座装着部と差込挿入部を受け入れる脚端部(主脚や継ぎ脚)に設けた脚座装着部を同部材で形成してなるもので、共通部材の採用で製造上の利点を有することになる。   Further, the joint leg structure of the table or the like according to claim 3 of the present invention is a leg provided at the leg seat mounting portion and the leg end portion (main leg or joint leg) for receiving the insertion insertion portion at the lower end of the leg (joint leg). The seat mounting portion is formed of the same member, and the use of the common member has a manufacturing advantage.

本考案の構成は、上記のとおりで、主脚と継ぎ脚の着脱連結や継ぎ脚の多段着脱連結に差込構造を採用することで、簡単な操作でテーブル等の高さの調整を行うことができると共に、いずれの高さ調整の状態であっても、何ら支障なく脚座の螺合調整による高さの微調整を可能としたものである。   The configuration of the present invention is as described above, and the height of a table or the like can be adjusted with a simple operation by adopting an insertion structure for the detachable connection of the main leg and the joint leg and the multistage detachable connection of the joint leg. In addition, it is possible to finely adjust the height by adjusting the screwing of the leg seat without any trouble in any height adjustment state.
