嵌合しうる上下方向を向く係合溝１４が切設さ
れ、係合溝１４の下端は、受片１５をもつて閉塞
されている。 A backrest support rod 13 is extended from the upper end of the back rod 3, and an engagement groove 14 facing in the vertical direction is cut into the front surface of the upper end, into which the protrusion 9 can be fitted without loosening. The lower end of 14 is closed with a receiving piece 15.
連結金具８の突条８ａは、支持杆１３の係合溝
１４に、上方より嵌入して、突条８ａの下端が、
係合溝１４下端の受片１５に、また、連結金具８
の水平突条１０が、係合溝１４の上端に当接し
て、背もたれ４の落下を防止している。 The protrusion 8a of the connecting fitting 8 fits into the engagement groove 14 of the support rod 13 from above, so that the lower end of the protrusion 8a
The connecting fitting 8 is also attached to the receiving piece 15 at the lower end of the engagement groove 14.
The horizontal protrusion 10 contacts the upper end of the engagement groove 14 to prevent the backrest 4 from falling.
連結金具８は、支持杆１３における係合溝１４
の左側面に螺挿した止めビス１６により止着され
ている。 The connecting fitting 8 is connected to the engagement groove 14 in the support rod 13.
It is fixed by a set screw 16 screwed into the left side surface of the.
本考案装置により背杆３に取付けた背もたれ４
は、裏板５と支持杆１３が、従来使用されたビス
等より、著しく大きい連結金具８を介して係合し
ているので、結合が極めて強固であり、かつ取付
作業は、上述で明らかなように、容易であり、ま
た、ビスの頭等が露呈しないので、体裁も良好で
ある。 Backrest 4 attached to back rod 3 using the device of the present invention
In this case, the back plate 5 and the support rod 13 are engaged with each other through the connecting fitting 8 which is significantly larger than the conventionally used screws, so the connection is extremely strong, and the installation work is easy as explained above. It is easy to install, and the appearance is good as the screw heads are not exposed.
なお、上述においては、背もたれ４の落下防止
用ストツパに、連結金具８の水平突条１０と、支
持杆１３の受片１５を併用したが、いずれか一方
を省略しても、機能上は、なんら差支えない。 In the above description, the horizontal protrusion 10 of the connecting fitting 8 and the receiving piece 15 of the support rod 13 are used together as the stopper for preventing the backrest 4 from falling, but even if one of them is omitted, the function is still the same. There is no problem.
