Description

Technical Field

[0001] This utility model relates to the field of office chair device technology, and in particular to an office chair that facilitates leg support. Background Technology

[0002] Office chairs refer to various chairs provided for convenience in daily work and social activities. OfficeMate divides office chairs into narrow and broad definitions. In a narrow sense, an office chair refers to a chair with a backrest that a person sits on while working at a desk. In a broad sense, an office chair includes all chairs used in offices, including executive chairs, mid-level chairs, guest chairs, staff chairs, conference chairs, visitor chairs, training chairs, etc.

[0003] To make it more comfortable for people to lean back in their office chairs, leg supports are sometimes installed at the bottom of the chairs.

[0004] However, typical leg supports are designed to be pushed forward to a certain position before the user places their feet on them. Since everyone's height and body type are different, this placement isn't always ideal. Therefore, we've designed a leg support that integrates with the office chair, allowing for angle adjustment and a wider range of extension. This enables various body types to comfortably place their feet on the footrest, thus providing better leg support. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes an office chair that is easy to support the legs, so that the leg support can be adjusted in angle and has a wider range of extension distance, so that various groups of people can comfortably place their feet on the footrest, thus facilitating leg support.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an office chair that facilitates leg support, comprising:

[0007] An office chair assembly includes a seat, a backrest installed on the rear side of the seat, armrests installed on both sides of the seat, and a support structure fixedly installed at the bottom of the seat.

Rotating columns are rotatably connected to both sides of the second fixing plate, and both rotating columns are fixedly connected to the middle of a connecting rod. A multi-layer telescopic mechanism is fixedly connected to one side of the connecting rod, and auxiliary sliding plates are slidably connected to the multi-layer telescopic mechanism. A connecting plate is fixedly connected to the ends of the two auxiliary sliding plates away from the connecting rod. A footrest is fixedly connected to the top of the ends of the two auxiliary sliding plates away from the connecting rod, and a baffle is fixedly connected to the top of the footrest on the side away from the connecting rod. The assembly also includes an angle adjustment structure that allows the connecting rod to rotate stably, facilitating operation by a person leaning against the seat.

Multiple diagonal bracing plates 6 are fixedly installed at the bottom of the base 5, and the multiple diagonal bracing plates 6 are circumferentially distributed at the bottom of the base 5. Casters 7 are fixedly installed at the bottom of the diagonal bracing plates 6.

[0029] A second fixing plate 10 is fixedly connected to the bottom center of the seat plate 1, and a first fixing plate 8 is fixedly connected to the bottom of the seat plate 1 near the back.

[0030] The second fixed plate 10 has rotating columns 15 on both sides for limiting rotation, and both rotating columns 15 are fixedly connected to the middle of the connecting rod 14.

[0031] A first sliding sleeve 19 is fixedly connected to the front end of the connecting rod 14, and a limiting block 20 is fixedly connected to the front inner wall of the first sliding sleeve 19. A second sliding sleeve 21 is slidably connected to the inner side of the first sliding sleeve 19, and a stop block 22 is fixedly connected to the rear outer wall of the second sliding sleeve 21. The stop block 22 can be pressed against the limiting block 20.

[0032] The second sliding sleeve 21 is slidably connected to an auxiliary sliding plate 23. A stop block 22 is fixedly connected to the rear outer wall of the auxiliary sliding plate 23. A limit block 20 is fixedly connected to the front inner wall of the second sliding sleeve 21. The stop block 22 can be pressed against the limit block 20.

[0033] A connecting plate 18 is fixedly connected to the side of the two auxiliary slide plates 23 away from the second slide sleeve 21, and a foot support plate 16 is fixedly connected to the top of the side of the two auxiliary slide plates 23 away from the second slide sleeve 21. A baffle plate 17 is fixedly connected to the top of the side of the foot support plate 16 away from the second slide sleeve 21.

[0034] Example 2: Based on Example 1, a technical means is added to facilitate the adjustment of the footrest 16 angle when a person leans on the seat 1.

[0035] Key reference Figure 2 This embodiment also includes a first fixing plate 8, a threaded rod 11, and a guide post 24.

[0036] The bottom of the seat plate 1 near the back is fixedly connected to a first fixing plate 8.

[0037] A guide post 24 is fixedly connected between the first fixed plate 8 and the second fixed plate 10. The second fixed plate 10 and the first fixed plate 8 are connected together by a threaded rod 11 for limiting rotation. A limiting slide plate 9 is threadedly connected to the outer wall of the threaded rod 11. The limiting slide plate 9 is slidably connected to the outer wall of the guide post 24 for limiting left and right. A rotating wheel 12 is fixedly connected to the rear end of the threaded rod 11.

[0040] The other parts are integrated into a single unit, namely the leg support assembly, which facilitates carrying and installation. When carried, the auxiliary slide 23 and the second slide 21 are both housed within the first slide 19.

[0041] After all components are installed, when a person needs to place their legs on the footrest 16, they first sit on the seat 1, bend over, and move the footrest 16 and baffle 17 to the front of the seat 1. This allows for easy adjustment of the angle of the footrest 16 and baffle 17. Then, the person clamps their legs around the footrest 16 and baffle 17, leans back against the backrest 3, and moves their hands backward to rotate the wheel 12. The rotating wheel 12 drives the threaded rod 11 to rotate, causing the limiting slide plate 9 to move forward. With the cooperation of the hinge rod 13 and connecting rod 14, the angle of the footrest 16 and baffle 17 is adjusted. After adjustment, the person presses their feet on the footrest 16 and pushes the baffle 17 to the desired position, thus providing comfortable foot support for people of various body types. The baffle 17 prevents the tilted footrest 16 from automatically retracting, making the device more stable.

[0042] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
