Description

  The present invention relates to a chair that can be connected and stacked, and more particularly, to a chair that can be connected and stacked in an orderly manner by connecting a plurality of chairs by two connecting seats that fit together.

  A commercially available chair has a frame made of metal pipes. The frame has legs on both sides, and back plate fixing pipes are respectively extended from the rear of the legs. A seat plate is fixed with screws to the top ends of the legs on both sides of the frame. A back plate is fixed with screws between the two back plate fixing pipes.

  In lecture halls and conference halls, many chairs are placed next to each other and arranged in a row. However, conventional chairs were not provided with a mechanism for connecting other chairs, so the white lines on the floor, etc. As a result, it took time and could not be arranged in an orderly manner. In addition, the chair moves during use, looks bad, and needs to be improved.

  In addition, when chairs are stacked on top of each other, the upper chair crosses the seat of the lower chair, so the center of gravity is applied to the front, and there is a risk of tilting and falling if only a few chairs are stacked. It was. In addition, there was a gap between the upper and lower chairs, and it took a lot of space to store and was inconvenient to transport. Therefore, improvement was awaited.

Japanese Patent No. 3789737

An object of the present invention is to provide a chair that can be connected and stacked, in which a plurality of chairs can be connected by two connecting seats that are fitted to each other and arranged in an orderly manner.

To achieve the above object, the present invention provides a chair that can be connected and stacked. The connectable and stackable chair of the present invention includes a frame, a seat plate, a back plate, a first connecting seat and a second connecting seat. The frame has legs on both sides. A plurality of fixed pipes are connected between the two legs. A back plate pipe extends obliquely upward at the top end of the rear part of the leg. The seat plate is fixed to the top end of the leg with a screw. The back plate is fixed to the two back plate pipes with screws. The first connecting seat is attached to the bottom of the leg on one side. The second connecting seat is attached to the bottom of the other leg. Moreover, the 2nd connection seat is provided with the 1st connection part on the outer side. When the two chairs are placed next to each other, the first connecting portion and the second connecting portion of the first connecting seat and the second connecting seat are fitted to each other, and the two chairs are fixed.

The chair which can be connected and stacked according to the present invention has the following three advantages. (1) A plurality of chairs can be neatly arranged side by side. (2) Since the handle hole is provided in the back plate, the chair can be carried with one hand. (3) By providing concave notches on both sides of the front part of the seat plate, even if a plurality of chairs are stacked, both front end sides of the upper chair enter the recessed part of the seat plate, so the center of gravity of the stacked chairs is Unlike conventional chairs, because it moves backward, there is less clearance between chairs, increasing the stacking height, stacking more chairs, reducing storage space, and transporting easily Can do.

It is a perspective view showing the state where a plurality of chairs that can be connected and stacked according to the present invention are stacked.

Embodiments of the present invention will be described below with reference to the drawings.

  Reference is made to FIGS. FIG. 1 is an exploded perspective view illustrating a chair that can be connected and stacked according to an embodiment of the present invention. FIG. 2 is a perspective view showing a combination of the first connecting seat and the leg. FIG. 3 is a perspective view showing a combination of the second coupling seat and the leg. FIG. 4 is a perspective view illustrating a chair that can be connected and stacked according to an embodiment of the present invention. FIG. 5 is a perspective view showing a state in which the first connecting seat and the second connecting seat are attached to the bottom of the frame. FIG. 6 is a perspective view showing a state in which a plurality of chairs are connected to each other. FIG. 7 is an enlarged view showing seven areas in FIG. As shown in FIGS. 1 to 7, the chair that can be connected and stacked according to the present invention includes a frame 10, a seat plate 20, a back plate 30, a first connecting seat 40, and a second connecting seat 50.

  The frame 10 has legs 11a and 11b on both sides. A plurality of fixed pipes 12 are connected between the two legs 11a and 11b. A back plate pipe 13 extends obliquely upward at the top ends of the rear portions of the legs 11a and 11b. The seat plate 20 is fixed to the top ends of the legs 11a and 11b with screws. The back plate 30 is fixed to the two back plate pipes 13 with screws. The first connecting seat 40 is attached to the bottom of the leg 11b on one side. Moreover, the 1st connection seat 40 is provided with the 1st connection part 41 on the outer side. The second connecting seat 50 is attached to the bottom of the other leg 11a. Moreover, the 2nd connection seat 50 is provided with the 1st connection part 51 on the outer side. When the two chairs are adjacent to each other, the first connecting portion 41 and the second connecting portion 51 of the first connecting seat 40 and the second connecting seat 50 are fitted to each other, so that the two chairs are Connected and fixed.

  Reference is made to FIGS. As shown in FIGS. 1 and 3, a fixing plate 14 that supports the seat plate 20 is fixed to the top ends of the legs 11a and 11b, and the seat plate 20 is fixed on the fixing plate 14 with screws. The seat plate 20 is provided with curved portions 21 that are curved and extended downward on both sides of the bottom end, and is sandwiched so as to tightly wrap both sides of the legs 11a and 11b of the frame 10. A positioning protrusion 22 is provided on the bottom of the seat plate 20 so as to correspond to the positioning hole 15 provided in the fixed plate 14 of the frame 10. A fixing hole 23 is provided at the bottom of the seat plate 20 to be fixed to the fixing plate 14 of the frame 10 with a screw.

  Reference is made to FIGS. FIG. 8 is a perspective view showing a state in which a plurality of chairs that can be connected and stacked according to the present invention are stacked. As shown in FIGS. 1, 3, and 8, recessed portions 24 are respectively provided on both sides of the front portion of the seat plate 20. Since the front end of the seat plate 20 faces obliquely downward, both sides of the front end of the upper chair enter the recessed portion 24 of the seat plate 20 when a plurality of chairs are stacked. Therefore, unlike the conventional chair, the center of gravity of the stacked chairs moves rearward, so that the gap between the chairs is reduced and the stacking height is increased. Thereby, compared with the past, more chairs can be stacked, storage space can be reduced, and it can convey easily.
