Description

[Detailed Description of the Invention] This invention relates to a chair used for lobbies, etc., which is constructed by combining a metal frame body and a seat body.

The purpose of this invention was to have a unique and progressively innovative appearance in terms of design, to be easy to assemble and manufacture, and to be able to create a variety of products with different seat shapes by changing some parts and using other parts in common. To provide a structure of a chair that allows the chair to be easily manufactured and is advantageous both in terms of manufacturing and component management.

Therefore, as shown in the illustrated embodiment, this invention has the following features:
Both side frame portions 1b, 1b are connected in a backward inclined manner from both ends of the U-shaped floor contact portion 1a, and a U-shaped portion extends between the side frame portions.
An endless pipe main frame 1 on which a letter-shaped backrest frame 1c is formed, and a pipe-made main frame 1 that is fixed to the middle part of the height of the both side frame parts 1b and extends forward in a substantially U-shape. The main frame body 1 is formed into a predetermined seat shape by a seat frame body 2 and a required number of metal vertical legs 3a and metal horizontal legs 3b, and has both ends of the vertical and horizontal legs.
A chair comprising a molded seat body 3 formed with a hook portion 4 that can be latched at a corresponding position, and a seat body 5 of a corresponding shape that is detachably combined with the molded seat body 3. This is related to.

The main frame 1 and the seat frame 2 are both made of metal pipes, and the seat frame 2 has both ends connected to the main frame 1.
are located inside the frame portions 1b, 1b on both sides, and are integrally joined to each other by bolts via a joint stabilizing member 6 made of resin. The molded seat body 3 is formed into a substantially net shape by welding vertical and horizontal beams 3a and 3b made of metal, such as thick iron wire, which have been given a decorative surface treatment such as chrome plating, at their intersections. be.
This is formed into a shape that allows the human body to rest deeply on the buttocks and sit comfortably, and a hook portion 4 is formed by bending both ends of the vertical and horizontal rods 3a and 3b. Backrest frame portion 1c of main frame body 1
It is removably attached to the main frame 1 by being hooked to the top and both sides of the seat frame 2 and the front and both sides of the seat frame 2, respectively. The seat body 5 is made by covering a cushion material such as urethane foam with an exterior material such as cloth or a synthetic resin sheet, and is made of the molded seat body 3 described above.
It is made into a corresponding shape, and if necessary, is connected to the molded seat body 3 at a plurality of locations with strings or the like.

Since this invention has the above-mentioned configuration, the unique net-like shape consisting of the vertical and horizontal legs 3a and 3b of the molded seat body 3 supporting the seat body 5 can be seen directly. As a chair with a pipe frame structure, the seat has a unique and progressively new appearance and is excellent in design. In addition, the main frame body 1 and the seat frame body 2
The assembly process is simple, as the pipe frame consisting of the molded seat body 3 and the seat body 5, which are separately produced, can be assembled into a product by simply combining them without the need for any auxiliary members. Not only that, but they can be disassembled and stacked in a so-called stacking state for storage and transportation, which is very advantageous in terms of component management and transportation. Furthermore, while using the above-mentioned pipe frame in common, by preparing molded seat bodies 3 and seat bodies 5 of various shapes and combining them, it is possible to adjust the seat depth, inclination, etc. Another advantage is that a variety of different chairs can be easily produced and provided.
