The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0034] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "front", "rear", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the combination or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention. In addition, during the description of the embodiments of the present invention, the positional relationships of "upper", "lower", "front", "rear", "left", "right", etc. of all devices in the drawings are based on Figure 1 As the standard.

[0035] As Figure 1 shown, the auxiliary standing-up handrail includes:

[0036] The support rod 1 is fixed with a support base 2 at the top to provide a fixed support for the handrail 3 thereon and to fix it after sliding and storing;

[0037] As shown Figure 1 and Figure 3 the support base 2 has a fixed card slot 21 and an arc-shaped chute 22 integrally connected to the fixed card slot 21. The fixed card slot 21 is used to limit the position of the armrest during use, and the arc-shaped chute 22 is used for the armrest to be stored

[0038] One end of the armrest 3 is rotatably connected to the support rod 1 through a rotating shaft 5. A horizontal chute 31 is also provided near the position of the rotating shaft 5, and a movable limit pull rod 6 is provided in the horizontal chute 31

[0039] As shown Figure 2 One end of the limit pull rod 6 is connected to the fixed end of the armrest 3 through at least one tension spring 7, and the other end is connected to the handle 9 at the free end of the armrest 3 through a pull rope 8. During storage, by pulling the handle 9, the limit pull rod 6 can be pulled through the pull rope, and then the limit pull rod 6 can be driven to slide in the horizontal chute 31. Correspondingly, the limit pull rod 6 can also be pulled out of the fixed card slot 21 of the support base 2 and then slide down to the bottom of the arc-shaped chute 22 integrally connected to the fixed card slot 21 to achieve storage. When the armrest is needed, use the handle to pull the limit pull rod 6 out of the arc-shaped chute 22 and slide it upward until it reaches the top and then send it into the fixed card slot of the support base 2

[0040] As shown Figure 2 and Figure 5 On the outer side of the armrest 3 of the assisted standing armrest near the handle end, there is also a fixed handle 10. The fixed handle 10 is provided with a handle chute 101 facing inward, and the handle 9 is connected to slide in the handle chute 101 of the fixed handle 10. At the same time, a limit protrusion 91 is provided on the handle 9 facing the outer side of the chute of the fixed handle 10. The purpose of setting the fixed handle is mainly to facilitate the user's grasping, and the limit protrusion 91 is used to limit the sliding stroke of the handle to prevent the handle from sliding out

[0041] The bottom of the arc-shaped chute 22 of the assisted standing armrest extends to the inner side of the support rod 1, so as to limit the position of the armrest after being stored in the lower part and prevent the armrest from hitting other things during excessive storage

[0042] The bottom of the support rod 1 of the assisted standing armrest is fixed on the support base plate 11, and the length of the support base plate 11 is longer than the unfolded length of the armrest, so as to maintain better balance performance of the whole assisted standing armrest during use

[0043] On the side of the support base plate 11 of the auxiliary standing-up handrail, a roller assembly 12 is also connected, which is used to move the entire auxiliary standing-up handrail. To ensure the safe use performance of the device, the roller assembly 12 is foldably connected to the side of the support base plate 11 through a roller rotating shaft 13 and a support lug 14. Thus, when moving the auxiliary standing-up handrail, the roller assembly is rotated and lowered for movement, and when the auxiliary standing-up handrail is in use, the roller assembly is retracted to ensure safe use.

[0044] The support base plate 11 of the auxiliary standing-up handrail is arranged in an I-shaped structure, which can ensure that the entire auxiliary standing-up handrail has a relatively light weight and can also ensure its use performance.

[0045] The support rod 1 of the auxiliary standing-up handrail is a lifting structure, usually arranged as a height-adjustable telescopic structure connected by bolts, or also a lifting and height-adjusting structure. When using these two structures, the user can adjust the use height of the handrail according to their own height and the placement position of the support rod, and the use range is wide.

[0046] One end of the handrail 3 of the auxiliary standing-up handrail close to the support rod 1 is also provided with a fixing plate 4. One end of the fixing plate 4 is fixed to the end of the handrail 3, and the other end is provided with a connection hole for fixing the handrail to other connecting parts, which is convenient for use against a wall or close to fixed structures such as fixed guardrails and fixing plates.

[0047] The number of the support rods 1 and the support seats 2 of the auxiliary standing-up handrail is two each, and the handrail 3 is fixed between the two support rods 1 and the two support seats 2, thus ensuring better stability of the handrail. Figure 7 It can also be seen from this that the tops of the two support rods 1 are connected with a handrail 16, which is used to supply people with inconvenient movement to move the auxiliary standing-up handrail or to assist in standing up at special positions.

[0048] From Figure 3 and Figure 6 It can also be seen that a protective cover 15 can be arranged outside the handrail 3 of the auxiliary standing-up handrail. The protective cover can wrap the entire handrail or can be semi-wrapped, but considering aesthetics, the effect of full wrapping is better. The protective cover 15 is used to improve the comfort of the handrail and play a reinforcing role in the handrail, improving its durability. The protective cover 15 is also provided with a semi-I-shaped pressing claw 17 near the rotating end of the handrail 3, which is used to realize pressing the handrail to ensure its stability.

[0049] The embodiments disclosed in the present invention are preferred embodiments, but are not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes, but as long as they do not depart from the spirit of the present invention, they are within the protection scope of the present invention.
