Description

Technical Field

[0001] The utility model relates to the technical field of chair armrests, in particular to a chair armrest with a hand rest capable of being adjusted in multiple directions. Background Art

[0002] In modern furniture design, armrests are an important part of chairs, sofas and other seating. They not only support human arms, but are also a key element to improve the overall comfort and practicality of the seating. Traditional armrest designs often appear in fixed forms, lacking flexibility and adjustability. However, with the deepening of ergonomic research and the growth of personalized needs, people have begun to realize that fixed armrests may not fully meet the needs of users in some cases. For example, differences in arm length, sitting habits, and usage scenarios may cause inconvenience or discomfort in the use of fixed armrests.

[0003] Chinese patent CN219353435U discloses a novel armrest structure, including a support member and a manual member, the joint end of the manual member is rotatably connected to the support member, the movable end of the manual member is suspended and can move relative to the support member, and the structure has a normal state and an active state. In the normal state, the structure is similar to a conventional armrest, and the movable end can only rotate in the horizontal direction; in the active state, the manual member is similar to an arm and can flexibly rotate in the horizontal and vertical directions; the joint end is connected to the support member and is relatively stationary with the support member. When the movable end moves, the entire armrest member also rotates, thereby changing the relative position of the armrest member and the support member and the shape formed by the two. The position where the user's arm can be placed is more arbitrary, thereby being able to adapt to more human body postures.

[0004] However, this solution has the following problems: first, the limit blocks and limit platforms are set outside, which are not beautiful and there is a risk of pinching during operation; second, the manual parts can only rotate in the horizontal and vertical directions, and there is no other adjustment structure, so the adjustable range is small. Utility Model Content

[0005] The purpose of the utility model is to address the deficiencies in the prior art and provide a chair armrest with a hand rest that can be adjusted in multiple directions. The vertical rotation is achieved by cooperating with a pivot part arranged on a transition seat, and a limiting structure between the two is arranged inside, thereby solving the problem of the risk of pinching caused by a limiting structure arranged outside.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A chair armrest with a multi-directionally adjustable hand rest comprises a support seat and a transition seat horizontally rotatably connected to the top of the support seat, a pivot member and a hand rest rotatably connected to the top of the pivot member, a pivot member is provided at the end of the transition seat, and the pivot member is rotatably connected inside the pivot member.

[0008] Preferably, the pivot member includes a rotating surface, and is provided with a positioning structure and a limiting structure protruding outward; the pivot portion includes an arc surface cooperating with the rotating surface, a limiting groove cooperating with the limiting structure, and at least one positioning groove cooperating with the positioning structure.

[0009] As a preference, the rotating surface is arranged at the bottom of the pivot member, and is coaxially arranged with the arc surface and the rotation center of the pivot member, and the rotating surface is in close contact with the arc surface when the pivot member rotates.

[0010] As a preference, the positioning structure is arranged on the rotating surface, and the arc surface is provided with two positioning grooves.

[0011] As a preference, the positioning structure is arc-shaped and smoothly transitions with the rotating surface.

[0012] As a preference, the limiting structure is arranged on one side of the pivoting member, and comprises a first limiting surface and a second limiting surface abutting against the limiting groove.

[0013] Preferably, a translation mechanism is installed in the palm rest, and the pivot member is rotationally connected to the translation mechanism.

[0014] Preferably, the translation mechanism comprises a translation seat and push blocks arranged on both sides of the translation seat, and a reset member is arranged between the push blocks and the translation seat.

[0015] As a preference, a slide groove cooperating with the translation seat is arranged in the hand rest, and the slide groove is provided with a plurality of cooperating grooves corresponding to the push block.

[0016] As a preference, it further comprises an armrest seat, and the support seat is sleeved outside the armrest seat and is slidably arranged up and down with the armrest seat.

[0017] The beneficial effects of the utility model are:

[0018] (1) The utility model realizes the rotation in the vertical direction by cooperating with the pivot part arranged on the transition seat through the pivot member, and the limiting structure between the two is arranged inside, so that the armrest is more simple and beautiful and improves the safety during adjustment.
