Abstract

It is easy to combine or separate the integrated seat and backrest and the steel frame with a fixed hardware to reduce the weight by minimizing the amount of wood and use the structural part as steel, which is convenient because it is composed of a three-dimensional shape by overlapping a number of wooden plywood sheets. and a chair with excellent mobility is provided. The chair is integrally configured to have a three-dimensional shape by overlapping a plurality of wooden plywood sheets, and includes a seat plate and a backrest having holes formed therein; an iron frame supporting the seat plate and the backrest; and a fixed hardware inserted into the hole to couple the seat plate and the backrest to the iron frame.

Description

chair {CHAIR}

The present invention relates to a chair.

In general, furniture such as chairs has been widely used for a long time. Chairs made of wood plywood have been developed in various shapes for a long time and are widely used. Currently, it is designed using a computer and manufactured by machine cutting and overlapping wooden plywood. This manufacturing method has also become common, and now a new type of design is required. The characteristics of the chair manufactured in the conventional way are that it is heavy or inconvenient to move. This is because a lot of plywood has to be used to maintain the structural form with wood alone.

In order to solve the conventional problems, the present invention can easily combine or separate an integrated seat and back part and a steel frame composed of a three-dimensional shape by overlapping a plurality of wooden plywood sheets by means of a fixed hardware, and minimize the amount of wood to reduce the weight. An object of the present invention is to provide a chair with excellent mobility and convenience by using a reduced and structural part of iron.

A chair according to the present invention is integrally configured to have a three-dimensional shape by overlapping a plurality of wooden plywood sheets, and includes: a seat plate and a backrest in which holes are formed; an iron frame supporting the seat plate and the backrest; and a fixed hardware inserted into the hole to couple the seat plate and the backrest to the iron frame.

The iron frame includes a pair of front vertical bars; a pair of rear vertical bars; a pair of upper rods; and a pair of lower rods, wherein the iron frame includes a pair of intermediate support rods connecting the pair of front vertical rods and the pair of rear vertical rods in the middle; a front locking bar interconnecting the pair of front vertical bars and limiting the downward rotation of the seat plate; and a rear locking rod interconnecting the pair of upper rods and limiting the rear rotation of the backrest, wherein the fixing hardware may be coupled to the pair of intermediate support rods.

The fixing hardware includes a pipe having a first screw thread formed on the outer circumferential surface of both ends and inserted into the hole; a pair of first nuts each screwed to the first thread of the pipe; a pair of first washers respectively coupled between the pipe and the pair of first nuts; a round bar having a second screw thread formed on both ends of the outer circumferential surface and having both ends supported by the pair of intermediate support bars through the pipe; a pair of second nuts each having one end screw-coupled to the second thread of the round bar; and a pair of second washers respectively coupled between the round bar and the pair of second nuts.

In the present invention, as a method of manufacturing a chair using birch plywood, it has been developed and used in various forms in the past, but unlike the existing form, a method for combining a seat plate and a backrest with an iron frame has been newly developed and is different from the form used recently. By differentiating, the method of manufacturing technology to make a chair with excellent mobility and convenience was sought. Therefore, by designing a method of connecting steel structures that conforms to these functions and achieves diversification of forms, it is intended to improve the quality of life by designing a chair that is more practical and user-friendly, as well as a beautiful looking chair.

Specifically, the seat plate and the backrest part and the steel frame, which are wooden parts made in various ways by means of fixed hardware, can be easily combined or separated separately, and the weight is reduced, thereby making it easy to manage and have mobility. Its main purpose is to make products with excellent design through the proper composition of wood and steel frames, so that they can be easily moved and separated and stored for use, since they can be combined and separated more easily and freely. Therefore, the present invention provides a new shape for the currently used chair by overlapping a plurality of wooden plywood sheets and produces a structural new coupling method by appropriately using a steel frame, so that it is easy to transport and loses weight from the chair of the existing shape. It can contribute to providing a convenient life by creating a newly designed, diverse and beautiful chair.

In the present invention, after cutting the plywood as shown in FIG. 1 and attaching several sheets to it, as shown in FIG. 2 , a chair is made and processed to have a partial three-dimensional shape. By manufacturing and combining the steel frame 100 as shown in FIG. 3 , By differentiating it from existing chairs, the functional part of the chair is solved, and the structural part is taken care of by the steel frame 100 to ensure safety, so that the excellent form and functional part can be completely solved. The chair according to the present invention includes a seat plate 12 and a backrest portion 1 , an iron frame 100 , and a fixed hardware 200 . The seat plate 12 and the backrest 1 are integrally configured to have a three-dimensional shape by overlapping a plurality of wooden plywood sheets, and a hole 14 is formed. The iron frame 100 supports the seat plate 12 and the backrest 1 .

The steel frame 100 is manufactured in a prismatic shape as shown in FIG. 3 and welded to secure structural stability, and the wood and iron frame 100 are manufactured as shown in FIGS. 3 and 4 to facilitate coupling and separation. The iron frame 100 includes a pair of front vertical bars 110; a pair of rear vertical bars 130; a pair of upper rods 120; and a pair of lower rods 140 . The iron frame 100 includes a pair of intermediate support rods 170 for connecting the pair of front vertical rods 110 and the pair of rear vertical rods 130 in the middle; a front locking bar 180 interconnecting the pair of front vertical bars 110 and limiting the downward rotation of the seat plate 12; and a rear locking rod 190 interconnecting the pair of upper rods 120 and limiting the rear rotation of the backrest 1 .

The fixing hardware 200 is inserted into the hole 14 and coupled to the pair of intermediate support rods 170 to couple the seat plate 12 and the backrest 1 to the iron frame 100 . The fixing hardware 200 includes a pipe 5, a pair of first nuts 6, a pair of first washers 62, a round bar 7, a pair of second washers 42, and a pair of support parts 8 ) is included. The pipe (5) is formed with a first thread (52) on the outer peripheral surface of both ends, and is inserted into the hole (14). A pair of first nuts 6 are each screwed to the first thread 52 of the pipe 5 . A pair of first washers 62 are respectively coupled between the pipe 5 and the pair of first nuts 6 . The round bar (7) has second threaded threads (72) formed on the outer peripheral surfaces of both ends, and passes through the pipe (5) so that both ends are supported by the pair of intermediate support bars (170). One end of the pair of second nuts 4 is screwed to the second thread 72 of the round bar 7, respectively. A pair of second washers 42 are respectively coupled between the round bar 7 and the pair of second nuts 4 . A pair of support parts 8 support the round bar 7 to be supported by the intermediate support bar 170 of the iron frame 100 .

The coupling method of the wooden seat plate 1 and the backrest 12 and the iron frame 100 constructed as described above is to insert the pipe 5 into the hole 14 of the wooden part as shown in FIGS. 3 to 5 . By inserting the fixing hardware 200, a connection method is used to facilitate coupling and separation. In more detail, as shown in FIG. 6 , it is possible to reduce the load by structurally solving the fixing method of wood and furniture, and at the same time to make it easier to move or store it by making it easier to combine and disassemble.
