Description

Prefabricated Iron Chair {ASSEMBLING TYPE STEEL CHAIR}

The present invention relates to a prefabricated iron chair, and more particularly to a prefabricated iron chair that can be easily assembled and installed on the spot simply by moving to the part to be installed.

Conventional chairs have generally fixed each unit member (backrest, seat plate, leg) constituting it to be integrated using nails and adhesives. In particular, in the case of iron chairs, each unit member is integrally formed or welded. Attaching was common. As a result, once manufactured products cannot be disassembled and assembled, they cannot expect to reduce the volume of the chair. Therefore, when a large quantity of products must be stored, a considerably large loading space is required. Due to the small amount of products that can be loaded in a limited space, there is a problem that it is insufficient to expect an effective transport, and the adhesive part easily peels off due to the dry and dry air of the chair during use. We found that there is a vulnerability such as shortening the lifespan.

In addition, even if any one of the unit members constituting the chair is damaged or broken, the entire chair must be discarded, thereby accompanying an uneconomical problem.

Therefore, in recent years, in order to solve the structural weakness and the uneconomical problems of the general chair, it was conceived that the components of the chair could be easily disassembled and assembled. However, since the assembly method is still made using only bolts and nuts, there is a disadvantage that the bonding strength is weak and the aesthetics are poor.

The object of the present invention is to solve the problems as described above, but to easily disassemble and assemble each component constituting the chair, prefabricated iron chair to have a more robust assembly strength while further reducing the number of members To provide.

Prefabricated iron chair according to the present invention for achieving the above object of the present invention a plurality of seating portion divided into a seat plate and the backrest so that the user can sit; A lower rod having a plurality of screw holes formed to support the seat plate of the seating portion by a bolt; An upper rod having a plurality of threaded holes formed to support the back of the seat by a bolt; A packing interposed between the seat plate and the lower rod of the seating portion and between the backrest and the upper rod of the seating portion so that the seat plate and the backrest of the seating portion can be stably coupled to the lower rod and the upper rod, respectively; A first leg portion and a second leg portion coupled to the lower rod and the upper rod, respectively, to support them; And a coupling adapter interposed therebetween for coupling the lower rod and the first leg and coupling the upper rod and the second leg.

At this time, the height adjustment member is mounted to the lower portion of each of the first leg portion and the second leg portion.

In addition, the coupling adapter has a Y-shape as a whole, a concave round wing portion is integrally formed on both sides so as to be easily seated on the lower end and the upper rod, the hollow first leg portion and the second leg portion It is characterized in that the insertion member is formed to protrude downward from the center to be fitted in.

Hereinafter, with reference to the drawings will be described in detail the prefabricated iron chair according to an embodiment of the present invention.

1 is a perspective view of a prefabricated iron chair according to the present invention, Figure 2a is an exploded perspective view of the prefabricated iron chair according to the present invention, Figure 2b is an enlarged perspective view of a portion A of Figure 2a, Figure 3 is in accordance with the present invention A side view of a prefabricated iron chair.

As shown in Figures 1 to 3, the prefabricated iron chair according to the present invention is composed of a plurality of unit members are used to combine at least one or more chairs to suit the area or various situations of the installation place.

Prefabricated iron chair of the present invention, the seat 10, the user can sit large, the lower rod 20 for supporting the seat plate 12 of the seating portion 10, the backrest 14 of the seating portion 10 The first and second legs 40 and the second legs 42 for holding them coupled to the upper rod 30, the lower rod 20 and the upper rod 30 to support them), and the lower rod A coupling adapter 60 interposed therebetween for the coupling of the 20 and the first leg 40 and the coupling of the upper rod 30 and the second leg 42.

The lower rods 20 and the upper rods 30 are formed with threaded holes 22 and 32 for coupling the seating portion 10, and the bolts 22 and 32 have bolts ( 92) is inserted to be able to couple the seating portion. At this time, a protrusion 24 is formed around the screw hole 22, and the protrusion is accommodated in the packing 80, thereby serving as a washer.

In order for the seating portion 10 to be stably disposed on the lower rod 20 and the upper rod 30, a packing 80 having a predetermined height is interposed therebetween, and the lower rod 20 and the upper rod are interposed therebetween. 30 may be fitted with a stopper 90 made of synthetic resin to give the aesthetic.

In addition, the support rod 44 may be integrally formed between the first leg portion 40 and the second leg portion 42 to further strengthen their holding force, and the lower surface of each leg portion thereof may be Only the screw hole (not shown) is closed and the height adjusting member 50 is mounted to the screw hole to adjust the height within a predetermined range so that the entire chair can be inclined.

Of course, the first leg portion 40 is made shorter than the second leg portion 42.

When describing the coupling adapter 60 in detail, as a whole having a Y-shape, both sides of the concave rounded wing portion 62 concave so as to be easily seated on the lower rod 20 and the upper rod 30 It is formed integrally with the insertion member 64 protrudes downward from the center so as to be fitted to the hollow first leg portion 40 and the second leg portion 42. In addition, the wing portion 62 is formed with a hole 63 so that the wrench bolt 94 penetrates, and the insertion member 64 is formed with a screw hole 65 for coupling.

Hereinafter, the assembly method of the prefabricated iron chair according to the present invention will be described in detail.

First, the number of chairs to be installed is selected and prepared by cutting the lower bar 20 and the upper bar 30 accordingly. Insert the coupling adapter 60 into the upper portion of the first leg portion 40 and the second leg portion 42, respectively, and then combine by using a bolt 96, screwing the height adjustment member 50 in the lower portion Let's do it. In such a state, the lower rods 20 are positioned on both wing portions 62 of the coupling adapter 60 coupled to the first leg portion 40 and coupled using the wrench bolt 94. Similarly, the upper rod 30 is positioned on both wing portions 62 of the coupling adapter 60 coupled to the second leg portion 40 and coupled using a wrench bolt 94.

Finally seating the seat 10 for the chair at the appropriate position of the lower rod 20 and the upper rod 30, the packing 80 is interposed therebetween and firmly coupled through the bolt 92, The prefabricated iron chair of the design is completed.

Such a prefabricated iron chair can be manufactured in a bench-type by installing a plurality of seating parts according to the user's needs, it can be easily and easily installed in a variety of places, such as a building lobby or an outdoor park.

On the other hand, as shown in Figure 5, after removing the stopper 90 from the existing iron chair can be installed by attaching an additional iron chair using a separate coupling member 110.

As described above, the prefabricated steel chair according to the present invention is manufactured in the form of a plurality of unit members instead of using welding to be combined and installed by a simple operation at an installation place, so that manufacturing and installation are simple and corrosion for a long time. It can be used without any concern, and there is an advantage that only a part can be replaced and repaired when a certain part is broken.

On the other hand, while the above has been described with reference to the preferred embodiments of the present invention, those of ordinary skill in the art various inventions within the scope without departing from the spirit and scope of the present invention described in the claims below It will be understood that modifications and changes can be made.
