以上説明したように、上記実施形態の椅子においては、別体をなす座体(15)と背凭れ(18)とを、左右1対の共通をなすブラケット(12)に取付けているため、部品点数や組立工数が削減される。 As described above, in the chair of the above embodiment, the separate seat (15) and backrest (18) are attached to the pair of left and right common brackets (12). The number of points and assembly man-hours are reduced.
また、背凭れ(18)の下端部の前面が、座体(15)の後端より下方においてブラケット(12)の後端に取付けられているため、ブラケット(12)や横フレーム(4)が背凭れ(18)の下部前方に位置して目立たなくなり、見栄えがよく、かつデザイン的に優れた椅子を提供することができる。 Moreover, since the front surface of the lower end of the backrest (18) is attached to the rear end of the bracket (12) below the rear end of the seat (15), the bracket (12) and the lateral frame (4) It is possible to provide a chair that is inconspicuous because it is positioned in front of the lower part of the backrest (18), has a good appearance, and is excellent in design.
さらに、背フレーム(19)の下端部の前面に、前後方向を向くめねじ孔(20)を設けているため、ブラケット(12)の背凭れ取付片(12c)の前方からめねじ孔(20)にボルト(21)を螺合することにより、座体(15)と別体の背凭れ(18)の背フレーム(19)を、ブラケット(12)に容易に固定することができ、かつボルト(21)も側方から見えないので見栄えがよくなる。 Furthermore, since the female screw hole (20) facing the front-rear direction is provided on the front surface of the lower end of the back frame (19), the female screw hole (20) from the front of the backrest mounting piece (12c) of the bracket (12). The back frame (19) of the backrest (18) separately from the seat body (15) can be easily fixed to the bracket (12) by screwing the bolt (21) to the bracket (12). 21) cannot be seen from the side, so it looks better.
背板(28)は、その両側端部が左右の背フレーム(19)の対向面に形成した凹溝(29)に嵌合され、かつ上下両端のカールした取付部(28a)(28b)を、背フレーム(19)の上下の対向面同士を連結する上下1対の横杆(24)に嵌合させて取付けられているため、ねじ等の固定手段を用いることなく、容易に、かつ安定して取付けることができる。 The back plate (28) is fitted with concave grooves (29) formed on opposite surfaces of the left and right back frames (19) at both side ends, and curled mounting portions (28a) (28b) at both upper and lower ends. Because it is fitted and attached to a pair of upper and lower ridges (24) that connect the upper and lower opposing surfaces of the back frame (19), it is easy and stable without using fixing means such as screws. Can be installed.
また、背板(28)の下部取付部(28b)は、前向円弧状にカールさせてあるため、そのカールさせた取付部(28b)が背板(28)の後方に露呈することがなく、しかも、座体(15)の後端下方と背凭れ(18)の下端前部との目立たない隅部に位置しているので、見栄えがよくなる。 In addition, the lower mounting portion (28b) of the back plate (28) is curled in a forward arc shape so that the curled mounting portion (28b) is not exposed behind the back plate (28). Moreover, since the seat body (15) is located in an inconspicuous corner between the lower rear end of the seat body (15) and the front lower end of the backrest (18), the appearance is improved.
管状の横フレーム(4)の下面に、上面が開口された箱状の取付金具(5)の上部を若干嵌合させて、全ての接触部を溶接し、支持脚(3)の上部に形成された、上面が開口する箱状の支持部(6)内に上記取付金具(5)を嵌合した状態で、取付金具(5)の底板(5a)と支持部(6)の支持基板(6c)とを、ボルト(11)とナット(10)とにより結合して、支持脚(3)の上部に横フレーム(4)を固定しているため、横フレーム(4)に対し支持脚(3)の取付部の位置決めがし易くなる。 The upper part of the box-shaped mounting bracket (5) whose upper surface is opened is slightly fitted to the lower surface of the tubular horizontal frame (4), and all contact parts are welded to form the upper part of the support leg (3). In the state where the mounting bracket (5) is fitted in the box-shaped support portion (6) whose upper surface is opened, the bottom plate (5a) of the mounting bracket (5) and the support substrate (6) 6c) is coupled with the bolt (11) and the nut (10), and the horizontal frame (4) is fixed to the upper part of the support leg (3). It becomes easy to position the mounting part 3).
また、取付金具(5)は、溶接により強固に横フレーム(4)に固着されており、かつ取付金具(5)と支持脚(3)の支持部(6)も、4個のボルト(11)とナット(10)により強固に固定されているため、横フレーム(4)に複数の座体(15)からの回転力が作用したとしても、支持脚(3)に対し横フレーム(4)が回動したりする恐れはない。 The mounting bracket (5) is firmly fixed to the horizontal frame (4) by welding, and the mounting bracket (5) and the support portion (6) of the support leg (3) are also provided with four bolts (11 ) And nut (10) so that the horizontal frame (4) is supported against the support leg (3) even if rotational force from a plurality of seats (15) acts on the horizontal frame (4). There is no fear of rotating.
本発明は、上記のように、左右方向に長い脚フレーム(1)に、複数の単体の椅子(2)を取付けたロビーチェア等の椅子以外に、通常の単体の椅子にも適用しうることは勿論である。 As described above, the present invention can be applied to a normal single chair in addition to a chair such as a lobby chair in which a plurality of single chairs (2) are attached to a leg frame (1) that is long in the left-right direction. Of course.
