[0002] A chair is a device used for sitting and resting, and it is widely used in people's daily lives. Senior-friendly chairs are designed for older adults, aiming to provide greater comfort, safety, and convenience. These chairs typically take into account the physical characteristics of older adults, such as stiff joints, weakened muscle strength, and decreased balance, and therefore their design places special emphasis on support, stability, and ease of use.

[0003] Chinese Patent No. CN210961099U discloses an elderly-friendly chair, comprising a seat, four legs fixedly connected to the four corners of the seat, and two armrests disposed above the seat. The four legs include two front legs and two rear legs. The two armrests are symmetrically arranged and fixedly connected to the front and rear legs located on the same side, respectively. The portion of the two armrests near the rear legs has an outwardly convex arc shape, and the portion of the two armrests near the front legs has an inwardly concave arc shape.

[0004] In the above solution, the shape of the front and rear sections of the armrests of the age-friendly chair is designed to conform to the ergonomic structure, making it easier for the elderly to get in and out of the chair. However, it has the following drawbacks: the armrests of this age-friendly chair cannot be flexibly adjusted according to the user's needs, which makes it difficult for the user to get up and sit down with the help of the armrests, thereby reducing the flexibility and effectiveness of the age-friendly chair. Utility Model Content

[0005] The purpose of this invention is to provide a chair suitable for the elderly, in order to solve the problem that the armrests of such chairs cannot be flexibly adjusted according to the user's needs, which makes it difficult for the user to get up and sit down conveniently with the help of the armrests, thereby reducing the flexibility and effectiveness of the chair.

[0006] To achieve the aforementioned utility model objectives, the present utility model adopts the following technical solution: a senior-friendly chair, comprising several support cylinders, all of which are fixed to the top surface of the chair body. A support plate is fixed to the top surface of each support cylinder, and a receiving groove is formed on the top surface of the support plate. Two through holes are formed on the bottom surface of the receiving groove, corresponding to the support cylinders. An armrest is placed on the inner wall of the receiving groove, and the armrest extends through the through holes into the support cylinders. Several limiting grooves are formed on one side of the armrest, and a strip-shaped through groove is formed on one side of the support cylinder. The inner wall of the support cylinder... An installation groove is provided, which corresponds to a limiting groove. A limiting post is slidably connected to the inner wall of the limiting groove. The limiting post is slidably connected to the limiting groove. A first spring is wound around the outer wall of the limiting post. One end of the first spring is fixed to the inner wall of the installation groove, and the other end of the first spring is fixed to the outer wall of the limiting post. A limiting block is slidably connected to the inner wall of the strip-shaped through groove. Two limiting blocks are connected by a connecting strip. Two second springs are fixed to the top surface of the limiting block. The other end of the second spring is fixed to the inner top surface of the strip-shaped through groove. The limiting block is in contact with the limiting post.

[0007] Preferably, a rubber pad is fixed to the top surface of the handrail.

[0008] Preferably, the top surface of the elderly-friendly chair body is provided with a placement groove, the inner wall of the placement groove is fixed with a first sponge pad, and the front side of the backrest of the elderly-friendly chair body is fixed with a second sponge pad.

[0009] Preferably, a flexible board is fixed to the front side of the backrest of the elderly-friendly chair body, and a protective pad is fixed to the outer wall of the flexible board.

[0010] Preferably, the top surface of the support plate has two snap-fit ​​grooves, the top surface of the support plate is provided with a placement plate, and the bottom surface of the placement plate is fixed with a plurality of snap-fit ​​posts, which are snap-fitted into the snap-fit ​​grooves.

[0011] Preferably, two handles are fixed to the back of the chair body for the elderly, and the outer wall of the handles is fixed with an anti-slip sleeve.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The armrests are fixed in place by the cooperation of the limiting block and the limiting post, allowing staff to flexibly adjust the height of the armrests according to the user's needs. This facilitates the user's getting up and sitting down, thereby improving the flexibility and usability of the chair. When adjustment is needed, staff apply an upward force to the connecting strip, causing the inclined surface on the limiting block to contact the inclined surface on the limiting post. The limiting post retracts into the mounting groove under the action of the first spring. At this point, staff can adjust the armrest up and down to the appropriate height. Then, the force on the connecting strip can be released, and the limiting block will reset under the action of the second spring, thus locking the limiting post into the limiting groove, completing the adjustment of the armrest height. Rubber pads enhance the comfort and anti-slip properties of the armrests. When users need to use the armrests to get up or sit down, the rubber pads provide a better grip, preventing slippage and making the use of the armrests more stable and safer.

[0014] Second, the combination of the first and second sponge pads provides soft support for the user, reducing pressure on the buttocks and back after prolonged sitting, effectively distributing body pressure, preventing excessive local pressure, and thus improving the user's sitting comfort. The flexible board supports the user's lower back, conforming to the user's lumbar curve, helping the user maintain correct posture, providing comfortable support, and reducing lower back fatigue.

[0015] Third, the snap-fit ​​design of the placement board provides users with a stable platform, making it convenient for them to eat or perform other activities, thus increasing the ease of use of the senior-friendly chair. The anti-slip sleeve increases the friction between the user's hand and the handle, effectively preventing slippage when pushing the chair and improving its stability during movement.
