Description

Technical Field

[0001] This utility model relates to a handrail structure, and more particularly to an adjustable handrail whose handrail surface can move significantly without dead angles. Background Technology

[0002] Currently, office chair armrests on the market are typically fixed, with some featuring height adjustment. When a user leans back, the armrests don't rotate accordingly. When the angle of inclination is slightly too large, the elbow only touches the back of the armrest surface, instead of the entire arm touching the surface. This prevents the arm from finding a comfortable resting position, impacting the user experience. Therefore, it's necessary to provide an adjustable armrest with a significantly wider, unrestricted range of motion. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an adjustable handrail with a handrail surface that can move significantly without dead angles, thus solving the problem that existing handrail structures cannot be adjusted with significant movement without dead angles.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is to provide an adjustable handrail with a handrail surface that can move significantly without dead angles. It includes a handrail body, wherein the handrail body is provided with a lower support surface and a handrail surface, the lower support surface and the handrail surface are snapped together, a surface fixing plate is provided between the lower support surface and the handrail body, the surface fixing plate is connected to the lower support surface by a fixing iron piece, a spring sheet is sleeved on the fixing iron piece, a transition piece and a connecting iron piece are provided between the lower support surface and the handrail surface, the lower support surface is provided with a groove, and the inner transition piece is embedded in the groove of the lower support surface.

[0005] The aforementioned adjustable handrail allows for a wide range of movement without any dead angles. The fixing plate of the handrail is elliptical in shape, and the handrail body is locked to the fixing plate by flat-head self-tapping screws.

[0006] The aforementioned adjustable handrail allows for a wide range of movement without any blind spots. The number of flat-head self-tapping screws is four, distributed around the perimeter of the surface fixing plate.

[0007] The aforementioned adjustable handrail allows for a wide range of movement without any dead angles. The transition plate, connecting iron plate, and lower support surface are locked together by an M6 nut. A rectangular washer is inserted into the groove of the connecting iron plate, and a hexagonal washer is provided on the rectangular washer.

[0008] Compared with the prior art, the present invention has the following advantages: the adjustable handrail provided by the present invention not only allows the handrail surface to move significantly without dead angles, but also has a simple overall structure, reliable function, and is easy to assemble.

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] Figure 1 This is a schematic diagram of an adjustable handrail in an embodiment of the present invention, where the handrail surface can move significantly without any dead angles.

[0014] Please see Figure 1 The adjustable handrail with a large-scale, non-dead-angle movable handrail in this embodiment of the utility model includes a handrail body 1, wherein the handrail body 1 is provided with a lower support surface 5 and a handrail surface 11, the lower support surface 5 and the handrail surface 11 are snapped together, a surface fixing plate 4 is provided between the lower support surface 5 and the handrail body 1, the surface fixing plate 4 is connected to the lower support surface 5 by a fixing iron piece 2, a spring piece 3 is sleeved on the fixing iron piece 2, a transition piece 6 and a connecting iron piece 7 are provided between the lower support surface 5 and the handrail surface 11, the lower support surface 5 is provided with a groove, and the inner transition piece 6 is embedded in the groove of the lower support surface 5.

[0015] The adjustable handrail in this embodiment of the utility model has a handrail surface that can move significantly without dead angles. The surface fixing plate 4 is elliptical in shape, and the handrail body 1 is locked to the surface fixing plate 4 by flat-head self-tapping screws 12.

[0016] The adjustable handrail in this embodiment of the utility model has a large-scale, non-dead-angle movable handrail. The transition plate 6, the connecting iron plate 7 and the lower support surface 5 are locked together by an M6 nut 10. A rectangular washer 8 is inserted into the groove of the connecting iron plate 7, and a hexagonal washer 9 is provided on the rectangular washer 8.

[0017] The adjustable armrest of this utility model embodiment is reliable in function.
