Description

Technical Field

[0001] The utility model relates to the technical field of household furniture. Specifically, it particularly relates to a computer chair with multi-gear adjustment. Background Art

[0002] In the current field of office and leisure furniture, computer chairs are one of the widely used devices. However, there are many limitations in the existing computer chair technology.

[0003] In terms of backrest adjustment, the backrest designs of most ordinary computer chairs are relatively simple. The backrest angles of some computer chairs are fixed, and users cannot adjust them according to their own needs. Maintaining a single posture for a long time is likely to cause physical fatigue. Especially during long-term office work or leisure use, this discomfort will be more obvious. Even some computer chairs have a certain backrest adjustment function, but the adjustable angle range is very limited. They can often only be adjusted within a small range and cannot meet the diverse requirements of users for comfortable backrest angles in different working states (such as concentrating on typing, reading documents, taking a short break, etc.) and rest needs (such as semi-reclining, full reclining, etc.). This limitation greatly restricts the applicable scenarios and user experience of computer chairs and reduces their practicality in different usage situations.

[0004] Regarding the footrest part, there are obvious deficiencies in existing seats with footrests. Some footrests adopt a fixed structure and cannot be adjusted in any way, which is very unfriendly to users of different heights. People of different heights have different leg extension lengths when using, and the fixed footrest cannot adapt to this difference, resulting in the legs not being properly supported, affecting blood circulation and overall comfort. Even some adjustable footrests have insufficiently flexible adjustment methods. For example, they may only have a simple telescopic function but cannot achieve multi-angle adjustment or linkage adjustment with other seat components, and cannot meet the needs of users for foot support in different lying positions.

[0005] Within the category of reclining seats, traditional rocking chairs and similar products have significant problems. One of the key problems is that they cannot be fully laid flat, which makes users unable to enjoy the comfortable experience of full lying down and restricts their application in rest scenarios. Moreover, when these reclining seats are in a state close to being laid flat, stability becomes a serious problem. Due to the deficiency of their structural design, there is no effective stable support structure during the放倒 process, resulting in easy tipping. This not only poses a safety hazard to users but also affects the convenience and comfort of use.

[0006] Furthermore, during daily use of computer chairs, users often need to keep items nearby, such as documents, office supplies, and electronic devices. However, traditional computer chairs often overlook this need in their design, failing to provide convenient storage space. Ordinary computer chairs lack dedicated storage areas, forcing users to place items haphazardly on the desk or nearby, increasing the risk of loss or inconvenience when needed, causing numerous inconveniences in daily use.

[0007] In summary, the shortcomings of these existing technologies prompted the development of this multi-level adjustable computer chair, which aims to comprehensively solve the functional and experiential problems existing in the use of computer chairs, and provide users with a more comfortable, convenient and multifunctional seating option.

[0034] U-shaped support frame 51, mounting base 52, support frame pivot 53; Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] Referring to the illustration, this embodiment provides a multi-position adjustable computer chair, including a computer chair frame. The computer chair frame includes main supports 1 disposed on both sides, and a horizontal crossbar 2 is disposed at the bottom of the main supports 1. A base frame 3 is disposed between the two main supports 1, and the two sides of the base frame 3 are mounted on the horizontal crossbar 2 by screws. A backrest gear adjuster 4 is fixedly installed on the rear side of the base frame 3, and a backrest frame 5 is fixedly installed at the end of the backrest gear adjuster 4 away from the base frame. A footrest pad 6 is installed on the front side of the base frame 3, and a U-shaped support frame 51 is disposed at the rear of the backrest frame 5.

[0037] Furthermore, a handrail 7 is welded to the upper part of the main support 1.

[0038] Furthermore, the base frame 3 is provided with multiple supporting horizontal bars 8 and supporting vertical bars 9 for bearing the weight of the human body, and the same sponge pad is placed on the supporting horizontal bars 8 and supporting vertical bars 9.

[0039] Furthermore, a telescopic assembly is provided between the foot pad 6 and the base frame. The telescopic assembly includes two sliding sleeves 10 fixed on the base frame. The same U-shaped frame 11 is slidably sleeved on the two sliding sleeves 10. A pad support rod 12 is provided in the middle of the U-shaped frame 11. The foot pad 6 is rotatably mounted on the pad support rod 12.

[0040] Furthermore, an installation assembly is provided between the U-shaped support frame 51 and the backrest frame 5. The installation assembly includes a mounting base 52 fixedly welded to the backrest frame 5. The mounting base 52 has pivot mounting holes on both sides, and a support frame pivot 53 is inserted into the pivot mounting holes. The support frame pivot also passes through the pivot mounting holes provided on the U-shaped support frame 51. The mounting base 52 is provided with an L-shaped slot, which allows the U-shaped support frame 51 to hang freely with the tilt length of the backrest frame until the maximum angle of 90 degrees is perpendicular to the ground.

[0041] Furthermore, the bottom of the U-shaped support frame is also provided with an anti-slip pad 54.

[0042] Furthermore, the distance between the support rod 12 and the front end of the U-shaped frame 11 is less than the width of the foot support 6.

[0043] Furthermore, the end of the U-shaped frame 11 is provided with a limiting sleeve 13 to prevent the U-shaped frame 11 from being completely pulled out.

[0044] Furthermore, the base frame 3, backrest frame 5, and footrest pad 6 are all fitted with sponge pads 14.

[0045] Furthermore, a storage bag 15 is hung on the handrail 7.

[0046] In practical use, first, the user pulls out the leg rest and flips it over according to the actual situation. When it is necessary to lay the computer chair completely flat, adjust the backrest gear adjuster to make the backrest parallel to the ground, and at the same time, place the U-shaped support frame 51 perpendicular to the ground to support the backrest. Because there is a crossbar at the bottom of the main frame, and the length of the crossbar is slightly longer than the side width of the main frame, the chair is very stable after being laid flat and will not tip over. Ordinary rocking chairs cannot be laid completely flat.

[0047] During the above-mentioned use, the backrest gear adjuster enables multi-angle adjustment of the backrest, providing users with a variety of comfortable postures; thus increasing the applicability of the computer chair.

[0048] When you need to lie flat, you can lower the backrest to be level with the ground, and then open the U-shaped support frame to further stabilize it. The U-shaped frame can be pulled forward from the sliding sleeve, and then the leg rest can be flipped up around the crossbar. The length of the U-shaped bar can be adjusted at will to suit people of different heights, so that users can lie flat more comfortably.

[0049] Meanwhile, the limiting sleeve also prevents the U-shaped bar from being pulled out excessively; in addition, when the leg rest is not in use, the leg rest pad can be flipped under the U-shaped bar and then the U-shaped bar can be pushed inward under the base frame; by hanging storage bags on the armrests, it is also convenient for users to place other miscellaneous items when using the computer chair.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
