（実施の形態１）
図１は、本発明の実施の形態１による椅子の構成を示す図である。図１において、本実施の形態１にかかる椅子１００は、座部１と、座部１の後端に立設された支柱２を備える。支柱２はその高さ方向に等間隔に設けられた複数の貫通孔２ａ，２ｂ，２ｃを備える。背もたれ３は止め具４を用いて支柱２に固定される。 (Embodiment 1)
FIG. 1 is a diagram showing a configuration of a chair according to Embodiment 1 of the present invention. In FIG. 1, a chair 100 according to the first embodiment includes a seat portion 1 and a support column 2 erected at the rear end of the seat portion 1. The column 2 includes a plurality of through holes 2a, 2b, 2c provided at equal intervals in the height direction. The backrest 3 is fixed to the column 2 using a stopper 4.

図２は、背もたれ３の構成を示す図であり、図に示すように、背もたれ３の背面３ａには、棒状部材４ａを、その長さ方向の中央付近と、背もたれ３の背面３ａの表面とをひも状部材４ｂで連結してなる背もたれ止め具４が、背面３ａの中心線上に上下に並べて２つ設けられている。棒状部材４ａは両端に丸みを設けた木製の棒からなり、その長さ方向の中央付近にひも状部材４ｂが固着されるくびれ部分が設けられている。また、棒状部材４ａの長さ方向の寸法は、支柱２の貫通孔の径よりも長い寸法となっている。ひも状部材４ｂは例えば太い木綿糸のような伸縮性のない丈夫な材料、又はゴムひものような伸縮性のある材料よりなり、その一端は背面３ａの表面に、縫付け、又は接着剤によって固着され、他端は棒状部材４ａの長さ方向の中央付近に設けられたくびれの部分に、結び付け、又は接着剤によって固着される。   FIG. 2 is a diagram showing the configuration of the backrest 3. As shown in the figure, on the back surface 3a of the backrest 3, a rod-like member 4a is disposed near the center in the length direction, and the surface of the back surface 3a of the backrest 3. Two backrest stoppers 4, which are connected by a string-like member 4 b, are provided on the center line of the back surface 3 a so as to be lined up and down. The rod-like member 4a is made of a wooden rod having rounded ends, and a constricted portion to which the string-like member 4b is fixed is provided near the center in the length direction. The length of the rod-shaped member 4a in the length direction is longer than the diameter of the through hole of the support column 2. The string-like member 4b is made of, for example, a strong material having no elasticity such as a thick cotton thread, or an elastic material such as a rubber string. One end of the string-like member 4b is sewn or adhered to the surface of the back surface 3a. The other end is fixed to the constricted portion provided near the center in the length direction of the rod-like member 4a by being bonded or adhesively attached.

次に、本実施の形態１による椅子の背もたれの着脱の動作について説明する。
まず、背もたれ３を支柱２に取り付ける動作について説明する。背もたれ３を支柱２に取り付けるときには、図３（ａ）に示すように棒状部材４ａを長さ方向に貫通孔２ｂ，２ｃをくぐらせて支柱２の反対側に出し、その後、棒状部材４ａを、貫通孔の貫通方向に対して垂直の方向に向ける。 Next, the operation of attaching and detaching the backrest of the chair according to the first embodiment will be described.
First, the operation of attaching the backrest 3 to the support column 2 will be described. When attaching the backrest 3 to the column 2, as shown in FIG. 3A, the rod-like member 4 a passes through the through holes 2 b and 2 c in the length direction and is put out to the opposite side of the column 2, and then the rod-like member 4 a is The direction is perpendicular to the through-hole penetration direction.

このとき、背もたれ３の背面３ａがレザー張りや布張りのように伸縮性のある材料からなるものである場合には、棒状部材４ａを引っ張ることによって、図３（ａ）に示すように背面３ａのひも状部材４ｂの連結点が引っ張られて貫通孔の貫通方向に伸び、棒状部材４ａの全体を支柱２の反対側に出すことができる。このように棒状部材４ａを支柱の反対側に出した後、棒状部材４ａを、貫通孔の貫通方向に対して垂直の方向に向けると、背もたれ３の背面３ａの収縮力によって棒状部材４ａが貫通孔２ｂ，２ｃの方向に引っ張られ、図３（ｂ）に示すように棒状部材４ａの両端部分が貫通孔２ｂ，２ｃの周縁部分に当接した状態となり、このようにして背もたれ３を支柱２に取り付けることができる。   At this time, when the back surface 3a of the backrest 3 is made of a stretchable material such as leather or cloth, the back 3a is pulled as shown in FIG. The connecting point of the string-like member 4b is pulled and extends in the penetrating direction of the through-hole, so that the entire rod-like member 4a can be put out on the opposite side of the column 2. After the rod-like member 4a has been put out on the opposite side of the column in this way, the rod-like member 4a is penetrated by the contraction force of the back surface 3a of the backrest 3 when the rod-like member 4a is oriented in a direction perpendicular to the penetration direction of the through hole. Pulled in the direction of the holes 2b and 2c, as shown in FIG. 3 (b), both end portions of the rod-like member 4a are in contact with the peripheral portions of the through holes 2b and 2c. Can be attached to.

図４は図３（ｂ）の状態を後方から見た図である。棒状部材４ａの長さ方向の寸法は、支柱２の貫通孔２ｂ，２ｃの径よりも長い寸法となっており、図３（ｂ）にも示されるように、棒状部材４ａの両端部分が貫通孔２ｂ，２ｃの周縁部分に当接し、背もたれ３を支柱２に固定することができる。   FIG. 4 is a view of the state of FIG. The length of the rod-like member 4a in the length direction is longer than the diameter of the through holes 2b and 2c of the support column 2, and as shown in FIG. 3B, both end portions of the rod-like member 4a are penetrated. The backrest 3 can be fixed to the support column 2 by abutting against the peripheral portions of the holes 2b and 2c.

なお、背もたれ３の背面３ａが金属板や木製板のように伸縮性のない材料からなる場合には、ひも状部材４ｂをゴム等の伸縮性のある材料よりなるものとすることにより、図３（ａ）に示す過程において、ひも状部材４ｂが伸長して、棒状部材４ａの全体を支柱の反対側に出すことができ、ひも状部材４ｂの収縮力によって棒状部材４ａがひも状部材４ｂとほぼ直角となった状態で貫通孔２ｂ，２ｃの方向に引っ張られ、図３（ｂ）に示すように棒状部材４ａの両端部分が貫通孔２ｂ，２ｃの周縁部分に当接した状態とされることとなる。   When the back surface 3a of the backrest 3 is made of a non-stretchable material such as a metal plate or a wooden plate, the string-like member 4b is made of a stretchable material such as rubber, so that FIG. In the process shown in (a), the string-like member 4b is extended, and the entire rod-like member 4a can be put out on the opposite side of the column. The rod-like member 4a is connected to the string-like member 4b by the contraction force of the string-like member 4b. Pulled in the direction of the through holes 2b and 2c in a substantially right angle state, the both end portions of the rod-like member 4a are in contact with the peripheral portions of the through holes 2b and 2c as shown in FIG. 3 (b). It will be.

次に、支柱２に取り付けた背もたれ３を支柱２から取り外す動作について説明する。背もたれ３を支柱２から取り外すときには、上述した取り付けの動作と逆の要領で、図３（ｂ）に示す状態から、棒状部材４ａを、その長さ方向が貫通孔の貫通方向と同じになるように立てて、該棒状部材４ａを貫通孔２ｂ，２ｃをくぐらせて支柱２から引き抜くことにより、容易に背もたれ３を支柱２から取り外すことができる。   Next, an operation of removing the backrest 3 attached to the support 2 from the support 2 will be described. When removing the backrest 3 from the support column 2, the length direction of the rod-like member 4a is the same as the penetration direction of the through hole from the state shown in FIG. The backrest 3 can be easily detached from the column 2 by pulling out the rod-like member 4a from the column 2 through the through holes 2b and 2c.

次に、本実施の形態１による椅子において、背もたれの高さ位置を調整するには、支柱２に、その高さ方向に配置された３つの貫通孔２ａ，２ｂ，２ｃのうち、図１に示すように、下側２つの貫通孔２ａ，２ｂを用いるか、図５に示すように、上側２つの貫通孔２ｂ，２ｃを用いるかによって、該背もたれ３の高さ位置の調整を行なうことができる。また、この貫通孔の配置間隔をより狭くし、より多くの貫通孔を設けることにより、背もたれ３の高さ位置の調整をより細かく行なうことができる。   Next, in the chair according to the first embodiment, in order to adjust the height position of the backrest, among the three through holes 2a, 2b, 2c arranged in the height direction of the column 2, FIG. As shown in FIG. 5, the height position of the backrest 3 can be adjusted depending on whether the lower two through holes 2a and 2b are used or the upper two through holes 2b and 2c are used as shown in FIG. it can. Further, the height position of the backrest 3 can be adjusted more finely by narrowing the arrangement interval of the through holes and providing more through holes.

以上のように、本実施の形態によれば、支柱２に、複数の貫通孔２ａ，２ｂ，２ｃを備え、背もたれ３に、棒状部材４ａとひも状部材４ｂよりなる背もたれ止め具４を設け、上記棒状部材４ａを、貫通孔をくぐらせて、その両端部分を支柱２の貫通孔の周縁の平面部分に当接させるようにしたので、デザイン性に優れたシンプルな構成で、背もたれの着脱、及びその高さ位置の調節を容易にできる椅子を提供することができる。   As described above, according to the present embodiment, the support column 2 includes the plurality of through holes 2a, 2b, and 2c, and the backrest 3 is provided with the backrest stopper 4 including the rod-shaped member 4a and the string-shaped member 4b. Since the rod-like member 4a passes through the through-hole, and both end portions thereof are brought into contact with the planar portion of the peripheral edge of the through-hole of the support column 2, with a simple configuration excellent in design, the attachment / detachment of the backrest, In addition, a chair capable of easily adjusting the height position thereof can be provided.

なお、上記実施の形態では、椅子の形状が脚部を有するタイプの椅子であるものについて説明したが、脚部のない座椅子タイプの椅子であってもよく、上記実施の形態と同様の効果を奏する。   In the above-described embodiment, the chair is a chair having a leg shape. However, the chair may be a chair without a leg, and is the same as the above-described embodiment. There is an effect.

本発明によれば、デザイン性に優れたシンプルな構成で、背もたれの着脱、及びその高さ位置の調節を容易にできる椅子を提供することができ、椅子製造等の分野において利用することが可能である。   According to the present invention, it is possible to provide a chair that can easily attach and detach the backrest and adjust its height position with a simple configuration excellent in design, and can be used in the field of chair manufacturing and the like. It is.
