Description

Technical Field

[0001] This utility model relates to the field of chair technology, specifically to a partially spliced ​​chair leg. Background Technology

[0002] Office chairs are a type of chair. Currently, most office chairs use five-star legs. To reduce the packaging volume of five-star legs and facilitate logistics and transportation, some existing five-star legs are usually designed to be detachable.

[0003] As disclosed in patent application number CN202220818930.8, this chair leg is designed for easy disassembly. It includes a tapered central tube and foot tubes. Inner sleeves are evenly welded to the outer surface of the tapered central tube, and an outer sleeve is welded to one end of each foot tube. Both the inner and outer sleeves are integrally formed from stamped iron. During transport, the chair leg can be disassembled into individual parts by removing the locking screws, reducing packaging volume for easier transport. In use, the inner sleeve is inserted into the outer sleeve, and the locking screws are then tightened to assemble the chair. The structure is simple and easy to install, thus meeting, to some extent, the industry's demand for detachable five-star chair legs. However, the above technical solution still has certain shortcomings. First, while all leg tubes are detachable, effectively reducing packaging volume, each leg tube needs to be assembled with the central tube using bolts and corresponding mating structures. This not only increases the assembly difficulty for users but also requires manufacturers to prepare corresponding connectors for each leg tube. The large number of components and the need to prevent missing connectors further increase costs. Second, machining accuracy errors are unavoidable in the processing of various chair leg components, such as welding position deviations between the inner sleeve and the tapered central tube, welding angle errors between the outer sleeve and the leg tube, and dimensional tolerances between the inner and outer sleeves. Simultaneously, assembly accuracy errors can occur due to factors such as the assembler's operating techniques and tool precision. These accumulated errors result in inconsistent assembly of the five-star chair legs. Some circumferentially adjacent leg tubes may fit precisely at the end near the tapered central tube, while the rest may have noticeable gaps, compromising the overall structural integrity and aesthetics of the chair legs. This leads to inconsistent appearance quality, affecting consumer acceptance and hindering product marketing and sales. Utility Model Content

[0021] Reference Figure 1-6A partially modular chair leg includes a central seat 1 and multiple support legs. The support legs are evenly distributed along the outer periphery of the central seat 1. At least one support leg is a detachable support leg 2 detachably connected to the central seat 1, while the remaining support legs are fixed support legs 3 non-detachably connected to the central seat 1. In this embodiment, one detachable support leg 2 and four fixed support legs 3 are provided. Thus, when assembling a five-star style chair leg, removing this one detachable support leg 2 reduces the shipping packaging volume by approximately one-third, resulting in a high cost-performance ratio. A decorative structure 100 separates the detachable support leg 2 from the fixed support leg 3, and a fixed decorative structure 200 separates the adjacent fixed support legs 3.

[0022] Furthermore, the upper part of the middle seat 1 is provided with a top decorative ring 11 located within the surrounding ring of multiple support legs. Top decorative structures 300 are provided between the detachable support leg 2 and the top decorative ring 11, and between the fixed support leg 3 and the top decorative ring 11, separating them. The top decorative structures 300 are evenly distributed along the outer circumference of the top decorative ring 11 and connected to form a ring-shaped decorative structure. The mating decorative structure 100 and the fixed decorative structure 200 are both connected to the ring-shaped decorative structure. The visual guidance effect of the ring-shaped decorative structure, the mating decorative structure 100, and the fixed decorative structure 200 attracts the user's attention, focusing their focus on these structures and thus causing them to overlook any potential gaps between the detachable support leg 2 and the middle seat 1 or other support legs after installation. Simultaneously, the ring-shaped decorative structure, the mating decorative structure 100, and the fixed decorative structure 200 form decorative patterns on the chair legs, thereby enhancing their aesthetic appeal.

[0023] In this embodiment, the top decorative structure 300 is a top decorative groove 301. The top decorative groove 301 corresponding to the detachable support 2 is composed of the upper surface of the middle seat 1, the inner end face of the detachable support 2, and the outer peripheral surface of the top decorative ring 11. The top decorative groove 301 corresponding to the fixed support 3 is composed of the upper surface of the middle seat 1, the inner end face of the fixed support 3, and the outer peripheral surface of the top decorative ring 11. The annular decorative structure is composed of multiple top decorative grooves 301 forming an annular decorative groove, thereby constructing a decorative pattern located at the upper end of the chair leg, making the overall visual effect more beautiful.

[0024] In this embodiment, the fixed decorative structure 200 and the matching decorative structure 100 have the same shape, so that after the detachable leg 2 is installed, its presence is visually weakened, making it difficult for people to distinguish between the detachable leg 2 and the fixed leg 3 when viewed from above, thereby improving the aesthetics of the chair legs. Furthermore, both the fixed decorative structure 200 and the matching decorative structure 100 are "7" shaped, and both include an upper decorative groove 101 and a side decorative groove 102. The outer end of the upper decorative groove 101 is connected to the upper end of the side decorative groove 102, and the inner end of the upper decorative groove 101 is connected to the top decorative groove 301. Thus, the connection structure of the upper decorative groove 101 and the side decorative groove 102 forms a continuous decorative line, further enhancing the decorative effect.

[0025] In this embodiment, the upper decorative groove 101 corresponding to two adjacent fixed legs 3 is formed by the upper surface of the intermediate seat 1 and the upper inner side surface of the two fixed legs 3; the side decorative groove 102 corresponding to two adjacent fixed legs 3 is formed by the side surface of the intermediate seat 1 and the inner side surface of the two fixed legs 3; the upper decorative groove 101 corresponding to two adjacent detachable legs 2 is formed by the upper surface of the intermediate seat 1 and the upper inner side surface of the two detachable legs 2; the side decorative groove 102 corresponding to two adjacent detachable legs 2 is formed by the side surface of the intermediate seat 1 and the inner side surface of the two detachable legs 2; the upper decorative groove 101 corresponding to two adjacent detachable legs 2 is formed by the upper surface of the intermediate seat 1 and the upper ... The upper decorative groove 101 between the leg 2 and the fixed support leg 3 is formed by the upper surface of the middle seat 1, the upper inner side of the detachable support leg 2, and the upper inner side of the fixed support leg 3. Correspondingly, the side decorative groove 102 between adjacent detachable support legs 2 and fixed support legs 3 is formed by the side surface of the middle seat 1, the inner side face of the detachable support leg 2, and the inner side face of the fixed support leg 3. This creates a continuous and unified decorative line between different legs, further enhancing the aesthetics and coordination of the overall structure of the chair legs. It makes it difficult for users to notice the assembly gap after the detachable support leg 2 is installed, thus improving the visual effect and sense of quality of the chair legs.

[0026] In this embodiment, the fixed support leg 3 and the intermediate seat 1 are fixed together by injection molding, casting, or welding. Different combination methods can be selected according to actual needs. Furthermore, the fixed support leg 3, the intermediate seat 1, and the detachable support leg 2 are all made of metal or high-strength plastic to ensure the stability and durability of the overall chair leg structure.

[0027] In this embodiment, both the fixed support leg 3 and the detachable support leg 2 have a lightweight groove 400 recessed upwards at their lower parts. Multiple structural reinforcing ribs 500 are integrally formed within the lightweight groove 400. This reduces the overall weight of the chair leg without affecting the structural strength, thereby achieving a dual optimization of lightweight and high strength.

[0028] In this embodiment, the intermediate seat 1 is provided with a connecting plug 12 integrally formed therewith. The number of connecting plugs 12 corresponds one-to-one with the number of detachable legs 2, that is, each connecting plug 12 can be detachably connected to a detachable leg 2. The inner end of the detachable leg 2 is provided with a connecting slot 21 for the connecting plug 12 to be inserted. After the connecting plug 12 is inserted into the connecting slot 21, the detachable leg 2 and the intermediate seat 1 are fixed by a fixed connection structure, thereby realizing the detachable connection between the detachable leg 2 and the intermediate seat 1.

[0029] In this embodiment, the fixed connection structure includes a fixing bolt 4, a fixing hole 23 is provided on the detachable support leg 2, and a connecting hole 14 corresponding to the fixing hole 23 is provided on the connecting insert 12. The screw of the fixing bolt 4 passes through the connecting hole 14 and is threadedly engaged with the fixing hole 23, thereby realizing the installation of the detachable support leg 2.

[0030] In this embodiment, the bottom of the connecting slot 21 and the end facing the middle seat 1 are both open to facilitate the insertion and engagement of the connecting plug 12 into the connecting slot 21. Furthermore, the connecting slot 21 has a positioning groove 22 extending recessed away from the middle seat 1 on its groove surface. One end of the connecting plug 12 is a positioning plug positioned and engaged in the positioning groove 22. This enhances the assembly quality of the connecting plug 12 and the detachable leg 2. Moreover, through the engagement of the positioning plug and the positioning groove 22, the detachable leg 2 can be fixed to the connecting plug 12 with only one fixing bolt 4, making the connection simple and convenient and effectively reducing the difficulty for users to install chair legs.

[0031] In this embodiment, the connecting plug 12 is integrally formed with the intermediate seat 1. The lower part of the connecting plug 12 is integrally formed with a connecting stop 13. The connecting stop 13 is used to fill the bottom opening of the connecting slot 21. At the same time, the edge of the connecting stop 13 abuts against the groove wall of the connecting slot 21, which can further improve the combined positioning effect of the connecting plug 12 and the detachable support 2.

[0032] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
