Description

[Detailed Description of the Invention] The present invention provides a connecting chair in which a plurality of seats are arranged in a row on a connecting rod that is installed horizontally between the upper ends of the legs that stand up at intervals. The purpose of this is to simplify the connection between the legs and the connecting rod to make assembly easier, and also to make it possible to select the attachment position of the legs to the connecting rod to adjust the length of the connecting rod. To provide a connected chair in which the number of legs can be increased or decreased accordingly.

The present invention will be explained below with reference to the illustrated embodiment. Fig. 1 is a front view of a connected chair according to the present invention, in which 1 and 1 are legs erected with a distance between the left and right, and 2 is the upper end of these left and right legs. With a connecting rod fixed to the section using the method described later and supported horizontally, 3.
... are seats arranged in rows on the connecting rod.

The leg 1 is made of a metal pipe, and a shoe 4 for supporting the leg vertically is fixed to the end of the leg, and a notch 5 is provided at the upper end for fitting the connecting rod 2. It is.

As shown in FIG. 4, the notch 5 is cut vertically into the upper end of the leg, and its shape is U-shaped to match the cross-sectional shape of the connecting rod made of square pipe.

The notch is formed deeper than the length of the vertical cross section of the connecting rod so that the upper surface 6 of the connecting rod is lower than the upper end 7 of the leg when the connecting rod is fitted.

In the figure, reference numeral 8 denotes a fixing fitting for fixing the connecting rod 2 that fits into the notch 5, and numerals 9, 9 indicate bolts welded to the leg 1 to fix the fixing fitting to the leg 1.

The fixing fitting 8 is formed in a cap shape, and its skirt portion 10 is fitted to the outer peripheral surface of the upper end of the leg to close the opening of the leg, and the lower edge of the skirt portion 10 is fitted into the notch 5 for connection. It is designed so that it can come into contact with the top surface of the rod 2.

The bolt 9 has a shaft portion 9a welded to the inner circumferential surface of the leg 1, avoiding the notch 5, so that the threaded portion 9b protrudes from the upper end of the leg. A through hole 11 previously opened in the fitting fitting 8 to be fitted.
, 11 to protrude from the upper surface 8a, and the oak)
By tightening 12.12, the fixture 8 can be fixed to the upper end of the leg.

In the figure, reference numeral 13 denotes a pin hanging from the center of the lower surface of the fixture 8, and reference numeral 14 denotes a fitting hole drilled in the upper surface of the connecting rod 2 for fitting this pin.

The present invention is constructed as described above, and when assembling the connecting chair, the seats 3 are arranged in rows along the length of the connecting rod 2 via the mounting brackets 15.

After that, the legs 1, 1 are exposed from below near both ends of the connecting rod, and the notches 5 at the upper end of each leg are fitted.

Thereafter, the fixing metal fitting 8 is placed over the upper end of the leg protruding from the upper side of the connecting rod 2, the lower edge of the skirt portion 10 is brought into contact with the upper surface of the connecting rod, and the bolts 9°9 are inserted into the through holes 11, 11. The parts 9b, 9b are penetrated and protruded from the upper surface 8a thereof, and nuts 12 and 12 are tightened to tighten the nuts 12 and 12, and the connecting rod is clamped in the notch 5, and the respective legs are attached and connected. This completes the assembly of the chair.

In addition, when fitting the fixing metal fitting 8, in this embodiment, the pin 13 hanging down from the lower surface is inserted into the insertion hole 14 of the connecting rod 2, and the nut 12 is tightened in this state.

In this way, when assembling the legs of the connecting chair of the present invention to the connecting rod that fixes the seat, the first step is to fit the notches formed in the upper end of the leg, cover the upper end with the fixing metal fittings, and then bolt the legs. As assembly can be completed by tightening the nut, assembly is extremely easy and quick, and when the nut is tightened, the lower edge of the skirt of the fixing fitting presses against the upper surface of the connecting rod, trapping both of them within the notch. At the same time, the upper end of the leg, which is divided into two parts by this notch, is prevented from expanding in diameter by the skirt of the fixing fitting, resulting in an extremely firm assembly.

As described above, the present invention is attached by fitting the notch 5 at the upper end of the leg to the connecting rod 2, so that it can be fixed at any position along the length of the connecting rod. Therefore, in addition to attaching the legs on the left and right sides as in the illustrated embodiment, it is also possible to place the legs in the middle.
If the number of seats is increased by lengthening the connecting rod, it is also possible to increase the number of legs in accordance with the length, which is extremely advantageous in manufacturing.

Note that the engagement between the pin 13 provided on the fixture 8 and the insertion hole 14 of the connecting rod 2 is advantageous in determining the position of the leg when attaching it to the connecting rod, and the movement of the leg is completely prevented after assembly. It is convenient to form a plurality of fitting holes 14 in advance at appropriate positions on the connecting rod, since this works effectively in blocking and ensuring fixation.

Of course, since this fitting hole is covered by the seat fixed on the connecting rod, the unused fitting hole does not spoil the appearance.
