Description

Modular chairs and stools

The invention relates to a chair and stool, in particular to a modular chair and stool.

A conventional wooden chair stool comprises four chair legs, four connecting columns arranged between the chair legs, and a chair board arranged at the top ends of the chair legs.

The chair legs are fixed to the chair plate by a plurality of screws or screws, and the connecting posts are also fixed to the chair legs by a plurality of screws or screws.

However, the structure of the chair is complicated and difficult to maintain, and the screws used for fixing the chair are exposed, which is not aesthetically pleasing.

Therefore, the purpose of the present invention is to provide a modular chair that can improve at least one of the above-mentioned disadvantages.

Therefore, the new modular chair stool includes a chair frame and a chair plate. The chair frame includes two leg members spaced apart along a first axis, and two support members installed between the leg members and spaced apart along a second axis perpendicular to the first axis. Each of the leg members has a beam connected between the support members, a first chair leg extending downward from the beam, and a second chair leg extending downward from the beam and spaced apart from the first chair leg along the second axis. The chair plate is detachably arranged on the support members.

The utility model has the advantages that the chair frame and the chair plate are separately manufactured modular structures with exquisite workmanship and are easy to maintain to extend the life cycle.

The present invention is described in detail below with reference to the accompanying drawings and embodiments.

1 and 2 , an embodiment of the novel modular chair comprises a chair frame 10 , a chair plate 5 detachably mounted on the chair frame 10 , and four screws 6 for locking the chair plate 5 to the chair frame 10 .

The chair frame 10 includes two leg members 1 spaced apart along a first axis X, two support members 2 installed between the leg members 1 and spaced apart along a second axis Y perpendicular to the first axis X, a first connecting column 3, and a second connecting column 4.

Each of the leg members 1 has a beam 11 connected between the supporting members 2, a first leg 12 extending downward from the beam 11, and a second leg 13 extending downward from the beam 11 and spaced apart from the first leg 12 along the second axis Y. The first leg 12 and the respective second leg 13 of each leg member 1 extend downward away from each other.

Each of the beams 11 has an inner side surface 111 facing the other beam 11, a first coupling groove 113 formed on the inner side surface 111 and located above the respective first chair legs 12, and a second coupling groove 114 formed on the inner side surface 111 and spaced apart from the first coupling groove 113 along the second axial direction Y. Each of the second coupling grooves 114 is located above the respective second chair legs 13. The first coupling grooves 113 correspond to each other along the first axial direction X. The second coupling grooves 114 correspond to each other along the first axial direction X.

3 and 4 , the center of each beam portion 11 is concave downward, and the projection of each beam portion 11 along the first axial direction X is in the shape of a smiling concave arc.

2 , a first connecting groove 121 is formed on each of the first chair legs 12. A second connecting groove 131 is formed on each of the second chair legs 13. The first connecting grooves 121 correspond to each other along the first axial direction X. The second connecting grooves 131 correspond to each other along the first axial direction X.

The two opposite ends of the first connecting column 3 are respectively inserted into the first connecting grooves 121 by mortise and tenon joints and then fixed by gluing. The two opposite ends of the second connecting column 4 are respectively inserted into the second connecting grooves 131 by mortise and tenon joints and then fixed by gluing.

The supporting members 2 are respectively located above the first connecting column 3 and the second connecting column 4 .

Each of the supporting members 2 has an inner side surface 21 facing the other supporting member 2, an outer side surface 22 opposite to the inner side surface 21, a peripheral surface 23 connected between the inner side surface 21 and the outer side surface 22, two tenons 24 connected to the peripheral surface 23, and two through holes 25 penetrating the peripheral surface 23.

The peripheral surface 23 of each supporting member 2 has two embedded surface portions 231 facing the beam portions 11 respectively, an upper surface portion 232 connected to the embedded surface portion 231 and facing the chair plate 5, and a lower surface portion 233 opposite to the upper surface portion 232.

The tenons 24 of each supporting member 2 are connected to the embedded surface portions 231. The tenons 24 of one supporting member 2 are respectively inserted into the first coupling grooves 113 and fixed by gluing, and the tenons 24 of another supporting member 2 are respectively inserted into the second coupling grooves 114 and fixed by gluing. In other words, each supporting member 2 is tenoned to the beam portions 11 at two opposite sides along the first axial direction X. The through holes 25 of each supporting member 2 penetrate from the lower surface portion 233 to the upper surface portion 232 and are spaced apart along the first axial direction X.

The chair board 5 includes a board body 51 and a rattan woven portion 52 wrapped around the board body 51. The board body 51 has a top surface 511, a bottom surface 512 opposite to the top surface 511, four screw holes 513 formed on the bottom surface 512 and corresponding to the positions of the through holes 25, and two openings 514 that penetrate the top surface 511 and the bottom surface 512 from top to bottom and extend along the first axis X. The openings 514 are located on the outer sides of the screw holes 513 and adjacent to the two ends of the board body 51 along the second axis Y. The screws 6 pass through the through holes 25 and are locked in the screw holes 513 to fix the chair board 5 to the support members 2. Furthermore, the screws 6 do not protrude downward relative to the lower side surfaces 233.

Referring to FIG. 3 and FIG. 4 , the chair plate 5 is spaced from the beams 11. Two opposite ends of the chair plate 5 along the second axis Y protrude outward relative to the supporting members 2. The center of the chair plate 5 is concave downward, and the projection of the chair plate 5 along the first axis X is in the shape of a smiling concave arc with two ends curved upward and a curvature similar to that of the beams 11.

Referring to FIG. 5 , the user's hand can pass through any of the openings 514 to hold the plate 51 to lift the modular stool.

The advantages of this novel modular chair and stool are described as follows.

The components of the chair frame 10 are connected by mortise and tenon joints, and the chair frame 10 and the chair plate 5 are separately manufactured modular structures. Only four screws 6 are needed to complete the assembly, and the workmanship is exquisite and easy to maintain to extend the life cycle. In addition, the design of the screws 6 being hidden in the through holes 25 makes the appearance of the modular chair more simple and beautiful.

The chair board 5 is a wood composite material made of rattan and wood, which is light in weight. The openings 514 are arranged on both sides to facilitate the user to grasp, move or adjust the sitting posture. The curved arc of the chair board 5 like a smile can better support the occupant, making the user more comfortable when sitting. In addition, the two ends of the chair board 5 extend outward, presenting a dovetail shape of the roof of traditional Taiwanese buildings, which not only makes the appearance elegant and beautiful, but also becomes the main identification feature of the shape.

In this embodiment, in addition to the screws 6, the chair frame 10 and the chair board 5 of the modular chair are made of low-carbon domestic wood with the "Taiwan Wood" label. The use of domestic wood can reduce the carbon footprint of long-distance cross-sea transportation when importing wood from Europe, America or other countries, reducing carbon emissions by more than 80%.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the present patent.
