It is bulged out relatively large in both directions. Here, the height of the back 18 is not necessarily the same as that of the backrest. It does not have to be tall enough to cover the entire surface of 13. 18b is a locking part that is integrally provided on both sides of the upper end of the back part 18, and this locking part 18b, place the seat 17 of the auxiliary tool 16 on the seat plate 12 of the chair 11, and After placing the back 18 in front of the backrest 13 of the chair 11, the back 18 is placed in front of the backrest 13 of the chair 11. and attach the auxiliary tool 16 to the chair 11. Note that the seat portion 17 and back portion 18 of the auxiliary tool 16 are the same as the auxiliary tool for a chair shown in FIGS. 1 and 2. It is formed from the same members as 1. Also, the height of the backrest 13 depends on the chair 11. Therefore, the installation position of the locking part 18b should correspond to the height of the backrest 13. shall be provided.
【００１６】 19は座部17の前端側中央部から前方下方側に伸び中間部で椅子11の座板12の下 側に向けて配設された支持杆で、19a はこの支持杆19を形成する上部支持杆、19 b は同じく下部支持杆である。 ここで、上部支持杆19a は座部17の前端側中央部に該部を支点にして前後に傾 動, 固定自在に軸19c により取付けられ、下部支持杆19b は上部支持杆19a の先 端部に該部を支点にして前後に傾動，固定自在に軸19d により取付けられている 。尚、上，下部の両支持杆19a，19bの長さは、図示の例に限られるものではなく 、また、両支持杆19a，19bは接続タイプ、つまり、一体型の杆体により形成して もよい。[0016] 19 extends from the central part of the front end side of the seat part 17 to the front downward side and is located under the seat plate 12 of the chair 11 at the middle part. 19a is the upper support rod that forms this support rod 19; b is also the lower support rod. Here, the upper support rod 19a is tilted back and forth at the central part of the front end side of the seat part 17 with this part as a fulcrum. It is movably and fixedly attached to the shaft 19c, and the lower support rod 19b is attached to the tip of the upper support rod 19a. It is attached to the end by a shaft 19d so that it can be tilted back and forth and fixed freely using this part as a fulcrum. . The lengths of the upper and lower support rods 19a and 19b are not limited to the illustrated example. In addition, both support rods 19a and 19b are of the connected type, that is, formed by an integral rod body. Good too.
【００１７】 20は、下部支持杆19bにその杆19bと交叉する向きの軸を介して取付けられてい る台状部材であり、該支持杆19bを中心に椅子11に腰掛けている者（図示せず） の右足の甲乃至は脛を載置する右側台状部材20aと同じく左足の甲乃至は脛を載 置する左側台状部材20b とから形成されている。ここで、左，右側の台状部材20 a ，20b の上面側は、足を長時間載置していても甲乃至は脛が痛まないようにク ッション性の部材で形成することが望ましい。[0017] 20 is attached to the lower support rod 19b via a shaft that intersects with the rod 19b. A person (not shown) who is sitting on the chair 11 centering on the support rod 19b. Similarly to the right platform member 20a on which the instep or shin of the right foot is placed, the instep or shin of the left foot is placed on the right platform member 20a. It is formed from a left platform member 20b on which it is placed. Here, the left and right platform members 20 The upper sides of a and 20b are designed with a clip to prevent the instep or shin from hurting even if the foot is placed on it for a long time. It is preferable to use a cushioning material.
【００１８】 21は、左，右側の台状部材20a，20bを下部支持杆19b に並行に取付ける取付部 材である。尚、左，右側の台状部材20a，20bを下部支持杆19b に対し夫々前後に 傾動，固定自在（首振り自在）となるように取付部材21に代え１本の取付軸（図 示せず）によって下部支持杆19bに取付けてもよい。また、下部支持杆19bと左右 の台状部材20a，20bを一体化し、上部支持杆19aの先端（下端）において、この 台状部材20を取付けるようにしてもよい。 本考案において、上記支持杆19は、上記例に限られず、座部17の左右側端、或 は、後端から座板12の下面側に延設するようにしてもよい。要は、台状部材20を 座板12の下面に設定できるものであればよいのである。 以上の各部材17乃至21により本考案の他の一例である椅子用補助用具16が形成 されている。[0018] 21 is a mounting part for attaching the left and right platform members 20a and 20b to the lower support rod 19b in parallel. It is a material. In addition, the left and right platform members 20a and 20b are moved forward and backward relative to the lower support rod 19b, respectively. In place of the mounting member 21, one mounting shaft (Fig. (not shown) may be attached to the lower support rod 19b. In addition, the lower support rod 19b and the left and right The platform members 20a and 20b are integrated, and this A platform member 20 may also be attached. In the present invention, the support rods 19 are not limited to the above example, and the support rods 19 are located at the left and right ends of the seat portion 17, or may extend from the rear end to the lower surface side of the seat plate 12. In short, the platform member 20 Any device that can be installed on the bottom surface of the seat plate 12 is sufficient. The above members 17 to 21 form a chair auxiliary tool 16 which is another example of the present invention. has been done.
【００１９】 而して、この補助用具16を椅子11に取付け、腰掛ける者は座部17にその臀部を 座部17の嵩高部17a に載せて座り、その状態で支持杆19の角度、即ち、上部支持 杆19a と下部支持杆19b の前後の角度を図 3の矢印で示したように調節して台状 部材20の前後の位置を決めて固定し、その後、腰掛けている者の左右の足の甲乃 至は脛を左，右側の台状部材20a，20bに夫々載置する。 従って、腰掛けている者の左右の足は、椅子11の座板12の下側において安定に 支持されるから、腰掛けている者の背筋が座板12に対して略垂直に伸びた状態で 姿勢が保持され、長時間に亘る事務作業でも疲れることが少なくなる。 また、腰掛けている者の上半身側は、図１，図２に示した椅子用補助用具１と 同様にこの補助用具16の背部18における腰掛ける者の腰椎に当たる部分18a によ って後屈（いわゆる腰砕け）を防ぐことができる一方、臀部から足の股が前下方 側に下がるようになってその姿勢が安定に保持され崩れることがない。[0019] Then, this auxiliary tool 16 is attached to the chair 11, and the person sitting down places his buttocks on the seat 17. When sitting on the bulky part 17a of the seat part 17, the angle of the support rod 19, that is, the upper support Adjust the front and rear angles of the rod 19a and lower support rod 19b as shown by the arrows in Figure 3 to create a trapezoid shape. The front and back positions of the member 20 are determined and fixed, and then the insteps of the left and right feet of the person sitting are Finally, place the shins on the left and right platform members 20a and 20b, respectively. Therefore, the left and right feet of the person sitting are stable under the seat plate 12 of the chair 11. Because it is supported, the back muscles of the person sitting are stretched out approximately perpendicular to the seat plate 12. Your posture will be maintained, and you will feel less tired even if you do office work for a long time. In addition, the upper body side of the person sitting is connected to the chair auxiliary tool 1 shown in Figures 1 and 2. Similarly, the part 18a of the back 18 of this auxiliary tool 16 that corresponds to the lumbar vertebrae of the person sitting on the This can prevent back bending (so-called lower back collapse), while also allowing the crotch of the leg to move forward and downward from the buttocks.
