Description

【考案の詳細な説明】（産業上の利用分野）本案は揺動可能な折畳み椅子に関するものであ
る。[Detailed description of the invention] (Field of industrial application) This invention relates to a swingable folding chair.

（従来の技術）折畳み椅子は、脚杆部を交叉せしめ、該交部を
軸結したもの或は、座布部枠に回動自在に脚杆を
連結したもの等椅子を前後に折畳むものがあり、
又脚杆を前後で交叉せしめて左右に折畳むものが
ある。(Prior Art) Folding chairs include those in which the leg rods intersect and the intersections are pivoted, or those in which the leg rods are rotatably connected to the seat frame, and the chair can be folded back and forth. There is,
There is also one in which the leg rods are crossed at the front and back and folded from side to side.

た。(Problem to be solved by the invention) When making the above-mentioned folding chair swingable, it is not necessary to particularly fold the legs of a chair that can be folded from side to side, so if the legs are bent, the legs can be bent. Although this is possible, it is complicated to manufacture and the legs become large, making it inconvenient to store. In addition, some chairs that can be folded back and forth do not have any shaft joints at all, but have the leg rods connected with chains, etc., and a seat cloth is pasted between the upper horizontal rods, but when folded, each rod frame is It fell apart and was inconvenient to handle.

畳み自在の制止杆で連結してなるものである。(Means for Solving the Problems) This proposal provides a chair that can be folded back and forth and can also be swung, with the mouth-shaped rod frames intersecting on the left and right sides, and the intersecting portions being pivotally supported to be movable. This was made possible by That is, a rectangular rod frame with a backrest provided on the upper part and a mouth-shaped rod frame are formed, and a long hole is provided approximately in the center of the side rod of each rod frame, and one of the two rod frames is placed inside the other. Adjacent long holes are connected by a shaft, a seat cloth is pasted between the upper horizontal rods, and the foot horizontal rods are connected by a foldable restraining rod.

従つて椅子は制止杆によつて足部横杆が更に広
がるのを制止されて椅子として機能すると共に、
長孔部内を軸が任意に移動できるので、座る人の
体重移動で各杆枠の傾斜が変化し、揺動可能とな

せしめ、軸を中心として各杆枠を立てると全体が
扁平となるものである。 Therefore, the chair functions as a chair by being prevented from further widening of the foot crossbars by the restraining rods, and
Since the shaft can move arbitrarily within the elongated hole, the inclination of each rod frame changes as the weight of the person sitting changes, making it possible to swing. Also, when folding, the restraining rods are bent in the middle, and each rod frame is erected around the shaft, making the entire object flat.

（実施例）本案の実施例を図面に基づいて次に説明する。(Example) An embodiment of the present invention will be described below based on the drawings.

するものである。該制止杆１０は略中央で折曲で
きるようにすると共に、折り曲げ方向に付勢する
発条１１を設けてなるものである。 The rod frame A has a rectangular frame (foot rods 1, side rods 2, side rods 3) with a back rod 4, which is an extension of the side rods 2, connected to the top of the rectangular frame (foot rods 1, side rods 2, and side rods 3) to form a rectangular shape. Similar to the rectangular frame of the rod frame A, the rod frame B is formed into a mouth shape consisting of a foot rod 1', a side rod 2', and a side rod 3'.
The width of the inner low rod frame B of each of the rod frames is formed to be slightly narrower than the rod frame A, and the rod frame B is placed inside the rod frame A. A connecting plate 6 having a long hole 5 is attached to the intermediate part of the side rods 2 and 2' of each rod frame, and a shaft 7 is inserted through the adjacent long hole 5, and a means for preventing it from coming off is provided as appropriate. A backrest 8 is rotatably installed on the back rod 4, a seat cloth 9 is attached between the horizontal rods 3 and 3', and a stop rod 10 connects the foot rods 1 and 1'. The stop rod 10 is bent approximately at the center and is provided with a spring 11 that biases it in the bending direction.

而かして足杆１，１′を広げると、座布９が張
られて椅子を形成するもので、座布９に体重が加
わつたとしても制止杆１０より足杆１，１′の開
脚が阻止され、且つ軸７が長孔５内を任意に移動

軸７の位置が自然に定まるものである。従つて長
孔５の長さの範囲内に於て任意に揺動できるもの
である。又背もたれ８を回動自在に設けておく

ものである。 When the leg levers 1 and 1' are expanded, the seat cloth 9 is stretched to form a chair, and even if your weight is applied to the seat cloth 9, the opening of the foot levers 1 and 1' is prevented by the restraining rod 10. Since the legs are blocked and the shaft 7 can move freely within the elongated hole 5, the position of the shaft 7 is naturally determined by the movement of the weight applied to the seat cloth 9. Therefore, it can swing freely within the range of the length of the elongated hole 5. Furthermore, if the backrest 8 is rotatably provided, the inclination can be adjusted to suit the inclination of the back of the person sitting.

（考案の効果）本案は前後に折畳む椅子に於て、揺動可能な椅
子を提供できたと共に、折り畳みに際しても、従
前の折畳み椅子と同様に取り扱うことの利便さも
有しているものである。(Effects of the invention) This invention provides a chair that can be swung back and forth, and also has the convenience of being handled in the same way as conventional folding chairs when folded. .
