Description

[Detailed description of the invention] This invention particularly relates to a chair made of rattan frame material.

Traditionally, there have been a wide variety of chairs made of rattan, but all of them require a lot of time and effort to make, and are difficult to mass produce, and are therefore expensive. It was worth it.

In addition, they have the disadvantage that they require a large amount of space for inventory at the time of sale, transportation, and storage when not in use.

This idea was created to solve the above-mentioned problems with the conventional methods, and because it is easy to assemble, mass production is possible.
Moreover, the purpose is to provide something convenient for inventory, transportation, storage, etc.

Hereinafter, the invention will be explained based on the illustrated embodiment. This invention consists of a leg frame 1 and a seat frame 2, each made of rattan, which are separately formed.
and a backrest frame 3 are removably assembled.

That is, the leg frame 1 is formed of a pair of left and right front legs 4 and a backrest locking part 5a which is formed higher than the front legs.
The leg rest 6 is integrally formed in a U shape and extends between the upper end of the front leg 4 and the middle part of the rear leg 5.

Further, two horizontal beams 7 are installed horizontally and vertically in parallel across a suitable height between the middle part of the front leg 4 and the lower middle part of the rear leg 5.

The backrest locking portion 5a of the rear leg 5 has a dowel 5b protruding inwardly, and each of the upper and lower horizontal bars 7 has two upwardly facing dowels 7a near the front and rear. It is installed protrudingly.

The seat frame 2 is made of rattan material and has a frame shape surrounding the front, rear, left, and right sides, and this frame is arranged as a pair of upper and lower frames at intervals equal to the height interval of the horizontal bars 7, The front and rear parts are connected by vertical connecting rods 9, and the entire seat frame is formed into a rectangular parallelepiped frame shape.

Locking holes 10a corresponding to the dowels 7a of the horizontal beam 7 are bored in each of the left and right frame members 10.10.

Further, a horizontal crosspiece 8 for attaching the backrest is provided spanning between the left and right frame members, and a dowel 8a is provided upward in the intermediate part of the horizontal crosspiece 8.
It has a protruding structure.

The backrest frame 3 has a crosspiece 11 arranged inside a framework surrounding the four sides, and its left and right width dimensions are equal to the inner width between the left and right leg frames 1, 1. There is.

At the upper part of the left and right frame members 12.12, there are locking holes 12a at positions corresponding to the dowels 5b protruding from the locking portions 5a.
is drilled.

Further, in the lower frame member 13, a locking hole 13a is bored at a position corresponding to the dowel 8a of the horizontal beam 8.

Each frame has the above-mentioned structure, and the lower left and right frame members 10 of the seat frame 2 are placed on the upper surface of the lower horizontal beam 7 of the leg frame 1, and
The upper left side of the seat frame 2 is placed on the upper surface of the upper horizontal beam 7 of the leg frame 1.
Place the right frame material 10 and insert the dowels 7a into the locking holes 10a.
A leg frame 1 and a seat frame 2 are removably assembled.

Further, the lower frame member 13 of the backrest frame 3 is placed on the horizontal beam 8 of the seat frame 2, and the dowel 8a is fitted into the locking hole 13a,
The dowel 5b of the leg frame 1 is inserted into the locking hole 12 of the backrest 3.
The leg frame 1 and the backrest frame 3 are removably assembled by fitting into the seat frame 2, and a mat 14 or the like is laid on the seat frame 2, as the case may be.

This invention consists of the above-mentioned structure, and each part is formed as a separate frame, and each frame can be assembled by simply fitting the dowels into the locking holes, so no special jig is required and anyone can easily assemble each frame. , it can be assembled quickly, and since it is detachably assembled, it can be disassembled for inventory at the time of sale, transportation, or storage at home, saving space and making it convenient to carry.

Moreover, in terms of strength, the seat frame that bears the most load is the front.

The back, left, and right sides are surrounded by a frame, and these frames are arranged in pairs at the top and bottom to form a rectangular parallelepiped frame, making it extremely sturdy.
To assemble with the leg frame, place the upper and lower two left and right frame members of the seat frame on the upper and lower two horizontal bars of the leg frame, respectively, and secure them with dowels in the upper and lower directions. Therefore, this type of chair, whose main load is a vertical load, is more firmly fixed, and the backrest frame is also secured at two points, the top and the bottom, so it has sufficient strength. be.
