New description: [New technical field] [0001 This creation is about the structure of a sip/mesh A 2 h road type to protect the arched beam arm, especially for tubular beam arms with different (four) and sectional shape changes. [Prior Art] [0002] Heyi and its material properties (such as: road and fragrance), g-pattern since ancient times - widely used in general or 家具 grade furniture 'but with silk forest material m, and modern people's environmental protection The rise of consciousness 'the production of pure wood raw materials is becoming more and more difficult, and the demand for high level of processing technology is high. It is difficult to produce in large quantities, so that the production cost cannot be effectively reduced. Since it is not a combination of benefits and environmental protection concepts, it has gradually become a consumer. Discard it. Therefore, replacing wood with other different raw materials (such as plastics and metals) as the main material of furniture is the direction of the industry 098205991 Form No. A0101 Page 2 / 21 pages 0982020154-0 M364455, but due to different The material properties (such as hardness, elasticity and structural strength) of raw materials (plastic, metal) and processing difficulty are different. Therefore, how to overcome the difference in processing, so that the raw material of the replacement wood can be used at home. It is a direction that needs to be worked hard to show the texture and durability that are not inferior. As shown in Fig. 1, it is a conventional wooden-shaped seat, which is mainly constructed by the lower bracket 4 being ringed on a peripheral edge of a seat 41, and the one (rear) side of the seat has a curved edge. And a plurality of downwardly extending legs 4 2 are disposed at the bottom of the lower bracket 4, and the two L-shaped side brackets 5 extend from one side of the lateral curved edge of the seat 4 1 with a straight edge, and The backrest beam arm 3 is connected by an arc-shaped backrest arm 3, and the backrest beam arm 3 is basically a curved arm structure. On the bottom side, a plurality of engaging faces 31 are coupled downwardly to the lower bracket 4, and finally, Between each of the engaging faces 31, and between the side bracket 5 and the engaging surface 31, a backboard 3 3 and a side partition 51 are respectively provided to form a complete wooden seat structure; In the structure, since the shape of the two-side bracket 5 combined with the backrest arm 3 is similar to that of the lower bracket 4 (and the seat 4 1 ), and in order to be ergonomic, the two-sided bracket 5 and the backrest arm are The combined shape is greater than the lower bracket 4 (and the seat 41), so that the backboard 3 3 and the side partitions 5 1 are in an upward direction. The expansion is arranged obliquely. At the same time, in order to meet the comfort requirements of the consumer's seat, the backboard 3 3 should be connected upward to the bottom edge of the backrest arm 3 on the side of the seat 41. Therefore, the backrest arm 3 The structure should be as shown in FIG. 2, and the connecting surface 31 of the same shape as that of the side bracket 5 is provided at the edge of the two end portions thereof to form a smooth connection with the side bracket 5, and the back arm beam is 3 middle section 3 2 is connected to the backboard at the inner edge 3 098205991 Form No. A0101 Page 3 / 21 pages 0982020154-0 M364455 3 upward oblique arc surface 321, so the middle section 32 basically has a large upper a small trapezoidal section (and the shape of the trapezoidal section may have an appropriate inclination angle on the opposite side of the oblique side as needed), and the connecting section 3 1 of the section 3 2 and the two sides have different curvatures and breaks The shape of the surface, for the wood material of the shape of the _, the processing of many lines of the straight wood billet is baked and heated several times, and then bent into a suitable curvature by the mold or hand, and then embedded and assembled Forming, grinding and forming, this processing method is extremely cumbersome The procedures have resulted in slower production speeds and less efficient production. It is difficult to achieve mass production. Increasingly expensive wood materials have seriously affected the manufacturing costs of the overall seats, resulting in non-economic benefits and reduced competitiveness. However, if the above-mentioned seat structure is mainly made of other materials (such as metal or hard plastic), it is preferable to use a hollow tubular structure based on material cost considerations, but components in some parts (such as: backrest) Beam arm 3) structure, which not only has different extensional curvatures (even 3D curvature changes with centerline or bottom surface not in the same plane), but also structural features with different cross-sectional shapes at various parts; thus, traditional Processing methods (such as metal extrusion molding) are not applicable. Therefore, how to overcome the bottlenecks encountered in processing, effectively and widely replace wood materials with other materials, to reduce production costs, is urgent for the relevant industry. The topic of hard work. In view of the above-mentioned shortcomings in the processing of the bow-and-bow arm structure of the wooden furniture, the creators have researched and improved the shortcomings of these shortcomings, and finally this creation has taken place. [New Content] 098205991 Form No. A0101 Page 4 of 21 0982020154-0 M364455 [0003] The main purpose of this creation is to provide a structure of a curved arch arm of a family, which is formed into a pre-form by using a plurality of brackets. The different curvature parts of the beam arms are arranged, and then the brackets are combined with each other to form a beam arm with a complete curved shape, thereby overcoming the processing bottleneck of the metal body which is not easily stamped into a tubular body having different curvatures and cross-section shapes. Another object of the present invention is to provide a structure of a curved arch arm of a home, which can replace the original wooden beam arm structure with a tubular structure formed of metal material, so as to reduce the material cost and enhance the competitiveness of the product. Another object of the present invention is to provide a knot-and-fork arch bridge structure which simplifies the processing procedure of the curved beam arm structure in the furniture to improve the efficiency of the overall furniture production. In order to achieve the above objectives and effects, the technical means adopted by the present invention are mainly composed of a plurality of segmented brackets, at least parts of which are extended with different curvatures, and the two ends adjacent to each bracket are connected. The joint ports are formed, and the sections of the same joint port having the same curvature and the same shape and size are joined to form a beam arm which is smoothly extended. According to the above structure, each of the brackets is composed of a component and a combined t-piece, and the component has a semi-closed long cover member whose width is obliquely expanded to one side and the opening is oppositely coupled to the opening. Whereas, a hollow tubular section that is laterally closed is formed. In order to achieve a more specific understanding of the above objects, functions and features of the present invention, the following figures are described as follows: [Embodiment] [0004] Referring to Figures 3 to 6, it can be clearly seen that The construction of the first embodiment is based on the beam arm A structure is set in the furniture (the figure is 098205991
