５の二つ割り体に形成されている。 First, to explain the structure, as shown in Figures 1 and 4, two bodies made of metal pipes bent into an approximately rectangular shape are connected at intervals by similar cross members at the front and back positions of their upper sides. A pipe 1 is formed, and a seat body 2 is fixed between the upper sides of the leg pipes 1, and back pipes 3 made of the same material are arranged in an upright manner on each rear end position of the upper sides. By attaching the backrest 8 to the chair, the chair is constructed into a single unit that can be stacked vertically, and the connecting member A for connecting the chairs laterally is formed by molding a synthetic resin material or the like as shown below. It is formed like this. That is, as shown in FIGS. 2 and 3a, this connecting member A is formed into two parts, an upper member 4 and a lower member 5, so that it can be easily fitted to the lower side 1a of the leg pipe 1. ing.

A semicircular groove 4a having a diameter dividing the portion into two equal parts is provided parallel to the longitudinal direction. The upper member 4 is formed into a horizontal surface 4d so that the connecting member A of the chairs directly above can be stably placed on the upper surface thereof when the chairs are stacked. From the intermediate zone of this horizontal surface 4d to the semicircular groove 4a, when the lower member 5 disposed below the upper member 4 and the lower side portion 1a are fitted in the upper and lower positions, both are connected to the lower side portion 1a.
In order to secure the screws at four positions, stepped holes 4b through which the screws 6 can be inserted are provided so as to be concentric with the screw fixing holes 1b provided in the lower side 1a of each position. has been done. A vertical guide surface 4c is formed on the outside of the upper member 4 in the longitudinal direction.

れている。 The lower member 5 of the connecting member A is formed symmetrically with respect to the lower member 4 in its main parts. That is, a semicircular groove 5a having a diameter obtained by equally dividing the hole portion of the lower side portion 1a into which the pipe material can be fitted is provided on the upper surface side of the rectangular cross section in parallel to the longitudinal direction. Further, the lower surface portion is formed into a horizontal surface 5g so that the chairs can be stably placed on the connecting member A of the chairs directly below when stacking the chairs. A stepped hole 5b having the same diameter is provided extending from the intermediate band of the lower surface portion to the semicircular groove 5a. A vertical guide surface 5f is formed on the outside of the lower member 5 in the longitudinal direction.

る一連の斜面体に形成されている。 On one side of the lower member 5, there is a semicircle shaped like a lower chord.
A box 5c is provided with a semicircular recess 5d inside thereof, which allows the convex piece 5e to be inserted and tightly fitted in the reverse position.
is integrally protruded. This box 5c has a semicircular convex piece 5e in the shape of a waxing chord that can be inserted and tightly fitted into a recess 5d disposed in the lower member 5 of another connecting member A attached to the lower side 1a of the adjacent chair.
is provided in an upright manner with the same central arrangement as the box 5c directly below it. The concave portion 5d inside the box 5c and the convex piece 5e on the box 5c are arranged so that the two connecting members A of the same shape are arranged with the top and bottom upside down as shown in Fig. 3a. When the protruding piece 5e of the other connecting member A is inserted into the recess 5d, the inner surfaces of the recess 5d and the protruding piece 5e on one side,
Each inner surface has a series of slopes with a depression angle exceeding the forming angle so that the inner surfaces of the recess 5d and the protruding piece 5e on the other side are in close contact with each other, and the degree of tight fitting between the two increases in proportion to the depth of insertion. formed in the body.

る。 When fitting the connecting member A with the above structure to one of the lower sides 1a of the leg pipe 1, the box 5c with the convex piece 5e of the connecting member A is in the upright position facing upward, and the box 5c is positioned outside the lower side 1a. Attach it so that it looks like this. Then, both semicircular grooves 4a, 5a are connected to the lower side 1 of each position where the screw fixing hole 1b is provided.
a from above and below, insert the screw 6 from the stepped hole 4b of the upper member 4 to the stepped hole 5b of the lower member 5 through the hole 1b at this position, and insert the screw 6 into the stepped hole 5b of the lower member 5. It is screwed into the nut 7 fitted in the hole 5b and tightened. The connecting member A is attached to the other lower side 1a of the leg pipe 1 in an inverted position with the box 5c facing downward and at a position outside the lower side 1a.

に連結することができる。 When connecting chairs with connecting members A fixed to the four sides of the lower side 1a in a horizontal direction, as shown in FIG. 3b, the box 5c of the right connecting member A serves as a vertical guide for the left connecting member A. Guided by the surfaces 4c and 5f, the protruding piece 5e of the right connecting member A smoothly slides into the recess 5d of the left connecting member A. Convex piece 5
Since e is formed in a semicircular shape, the protruding piece 5e helps smooth the sliding action into the recess 5d.
Since both the convex piece 5e and the recess 5d are configured as a series of depression-shaped slopes, the degree of tight fitting between the two is increased in proportion to the insertion depth, and ultimately, they can be connected in a tight state. . This allows each chair to be easily and quickly connected to regular connected chairs with no wasted space in the lateral direction.

た椅子に組成することも可能である。 In the above embodiment, the connecting member A is connected to the upper member 4.
However, the connecting member according to this invention is not limited to the above-mentioned embodiments, and may be formed as a unitary body from the beginning, and the lower side portion 1a
It is also possible to form the above-mentioned chair by bending the pipe material in a state in which it has been fitted in advance to the pipe material at the position where it will be.
〔考案の効果〕
同一形状の連結部材を正位及び逆位の姿勢で
脚パイプの１対の下辺部１ａに取り付けること
により連結部材は１種類で済むから製造コスト
が低減される。[Effects of the invention] By attaching connecting members of the same shape to the pair of lower side portions 1a of the leg pipes in normal and reverse positions, only one type of connecting member is required, thereby reducing manufacturing costs.
