Description

本発明は、アウトドアライフや外出時に小さく折り畳んで人が持ち運ぶことを容易にした携帯用椅子に関するものである。 The present invention relates to a portable chair that is easily folded and carried by a person during outdoor life or when going out.

従来の携帯用折り畳み椅子は、所謂パイプ椅子と呼ばれるもので、その構造は方形のパイプ２個をクロスさせ、その上部にシートを張ることで椅子として利用されていた。構造が簡単であるものの嵩張るため、それを持ち運ぶ時は自動車などの車両を使用することが多かった。 A conventional portable folding chair is a so-called pipe chair, and its structure has been used as a chair by crossing two square pipes and stretching a seat on the top. Although the structure is simple, it is bulky, so vehicles such as automobiles are often used to carry it.

そのために次のような問題点があった。
従来のパイプ椅子に代表される携帯用椅子は、構造が二つ折で単純ではあるものの、閉じて収納した状態であっても面状にしか折り畳めず嵩張るため、人が持ち運ぶには適していなかった。そのために運搬手段が限定され、自動車などの車両を利用するアウトドアライフ等にしか利用できなかった。
本発明は、以上の問題点を解決するためになされたものである。Therefore, there were the following problems.
Although portable chairs represented by conventional pipe chairs are simple in structure with two folds, they can only be folded into a flat shape even when they are closed and stored, and are not suitable for carrying by people. . For this reason, the transportation means is limited and can only be used for outdoor life using vehicles such as automobiles.
The present invention has been made to solve the above problems.

管状の本体の両端に内側に折り畳むことのできる上４本、下４本の脚部を本体軸方向から見てＸ字になるように支持することができる支持部と、この上脚上端部に水平な天板部を形成し、この天板部には両端を支持棒によって支えられたシート部の、当該支持棒両端部に形成された突起が着脱可能な差し込み穴を形成し、上記管状の本体の両端にはシート部を本体内に丸めて収納するための蓋となるキャップを設けたことを特徴とする携帯用椅子。 On the upper end of the upper leg, there are a support part that can be folded inward at both ends of the tubular main body so that the upper and lower four legs can be supported in an X shape when viewed from the axial direction of the main body. A horizontal top plate portion is formed, and the top plate portion is formed with insertion holes in which the protrusions formed on both ends of the support rod are detachable on the seat portion supported at both ends by the support rod, A portable chair characterized in that a cap serving as a lid is provided at both ends of the main body to wind and store the seat portion in the main body.

棒状に収納できるため、人が持ち歩くことが容易となり、アウトドアライフに限らず、街中への外出などの折にもハンドバック等に入れて持ち歩くことができる。
また、管状の本体のみを使用し、シート部の代わりに外出先で有り合わせの金属や木製のボードを利用することで、簡易テーブルとして使用することも可能である。Since it can be stored in a rod shape, it is easy for people to carry around, and it can be carried in a handbag etc. not only for outdoor life but also when going out to the city.
Moreover, it is also possible to use as a simple table by using only a tubular main body and using a common metal or wooden board on the go instead of the seat portion.

以下、本発明の実施の形態（実施例）を説明する。
（イ）本管（１）の両端に上下各４個計８個の支持部（２ａ〜２ｈ）を本管軸方向から見てＸ字になるように、また本管軸側面方向から見て本体両端部よりも外側に一定の角度で傾いた状態で上脚（３）と下脚（４）を支持することができるように取り付け、その内側に折り畳み式の上脚（３）４本と下脚（４）４本をボルトナット（５）にて軸支する。その際、折り畳み時に左右の脚がかち合わないようにするため、図２に示すように左右両端８個の支持部（２ａ〜２ｈ）のうち４個の支持部（２ｃ，２ｄ，２ｇ，２ｈ）のボルトナット（５）の取り付け位置を脚先端部方向へずらしておく。
（ロ）上脚（３）の先端部に後述のシート部固定用穴（６）を持つ天板部（７）を形成する。
（ハ）上脚（３）４本のそれぞれに、使用時に上脚（３）による内側への倒れ込み防止の目的で、上脚（３）と支持部（２）の結合部分の形状に合わせて、断面が馬蹄形をした円筒状で可動式のストッパー（８）を取り付ける。
（ニ）下脚（４）の接地部分となる先端部は、使用時の安定感を保持するためと接地部分に傷を付けないようにするため半球状にする。
（ホ）本管（１）とは別に、上脚（３）の天板部（７）差し込み用突起（９）を両端部に折曲形成した２本の支持棒（１０）および支持棒（１０）に架設されたシート（１１）から成るシート部（１２）を用意する。
（ヘ）シート部（１２）を本管内に収納するために、本管（１）両端のそれぞれに蓋をすることが可能となるキャップ（１３）を用意する。
本発明は、以上の構成よりなっている。
本発明を利用するときは、上脚（３）と下脚（４）とを本管（１）の両端にある支持部（２ａ〜２ｈ）内にて起こして台部分とし、上脚（３）のストッパー（８）を上脚の支持部（２ａ，２ｂ，２ｃ，２ｄ）のボルトナット（５）部分まで移動させることにより上脚（３）を固定し、シート（１１）を架設した支持棒（１０）を上脚（３）に設けた天板部（７）に形成したシート部固定用穴（６）に差し込むことで、椅子として使用する。使用後の収納時には、シート部（１２）を天板部（７）から取り外し、上脚（３）と下脚（４）を折り畳んだ本管（１）内に丸めて挿入し、本管（１）の両端にキャップ（１３）をかぶせることにより棒状に収納する。Hereinafter, embodiments (examples) of the present invention will be described.
(B) At the both ends of the main pipe (1), four support parts (2a to 2h) at the top and bottom, respectively, are X-shaped when viewed from the main shaft direction and viewed from the main shaft side surface direction. The upper leg (3) and the lower leg (4) are attached so as to be able to support the upper leg (3) and the lower leg (4) in a state inclined at a certain angle outward from both ends of the main body. (4) Four bolts are supported by bolts and nuts (5). At that time, in order to prevent the left and right legs from being folded when folded, four support portions (2c, 2d, 2g, 2h) out of the eight support portions (2a to 2h) at both the left and right ends as shown in FIG. ) Is shifted in the direction of the leg tip.
(B) A top plate portion (7) having a later-described sheet portion fixing hole (6) is formed at the tip of the upper leg (3).
(C) In order to prevent the upper leg (3) from collapsing inward by using the upper leg (3) in each of the four upper legs (3), the upper leg (3) should be matched to the shape of the joint between the upper leg (3) and the support part (2). A cylindrical, movable stopper (8) having a horseshoe shape in cross section is attached.
(D) The tip of the lower leg (4), which serves as the ground contact portion, is hemispherical in order to maintain stability during use and to prevent the ground contact portion from being scratched.
(E) Separately from the main pipe (1), the top plate part (7) of the upper leg (3), two support bars (10) and support bars ( A sheet part (12) composed of the sheet (11) installed on 10) is prepared.
(F) In order to store the seat portion (12) in the main pipe, a cap (13) is prepared which can cover both ends of the main pipe (1).
The present invention has the above configuration.
When using the present invention, the upper leg (3) and the lower leg (4) are raised in the support portions (2a to 2h) at both ends of the main pipe (1) to form a base portion, and the upper leg (3) The upper leg (3) is fixed by moving the stopper (8) of the upper leg to the bolt nut (5) portion of the upper leg support portions (2a, 2b, 2c, 2d), and the support bar on which the seat (11) is installed (10) is used as a chair by inserting it into the seat portion fixing hole (6) formed in the top plate portion (7) provided on the upper leg (3). When stored after use, the seat (12) is removed from the top plate (7), the upper leg (3) and the lower leg (4) are folded and inserted into the folded main pipe (1), and the main pipe (1 ) And put the cap (13) on both ends.
