Description

A folding armrest structure and method of use for health care beds

Technical field

The present invention relates to a foldable armrest of a health care bed, and in particular to a method of using the foldable armrest structure, which belongs to the technical field of armrest structures.

Background technique

For example, the application number: 202022190297.6 discloses a quick-folding armrest for a nursing bed, which includes two sets of armrest assemblies. The two sets of armrest assemblies are respectively arranged on both sides of the bed frame in the width direction. The armrest assemblies include cross bars and limit blocks. Limit pins, limit chucks and several swing bars. The lower ends of some swing bars are hinged with both sides of the bed frame respectively. The upper ends of some swing bars are hinged with the cross bars. The ends of the cross bars are bent downward. The upper end surface of the limit block Perpendicular to one side wall of the limit block, the limit block is fixedly connected to one of the swing bars through this side wall. The upper end surface of the limit block is close to the hinge of the corresponding swing bar and the cross bar, and the limit block is in a relatively corresponding position. The side of the swing bar is close to the bending direction of the cross bar. There is a limit groove on the bent end face of the cross bar. There is a folding hole on the side wall of the limit chuck. The starting end of the limit chuck is in the limit groove and the limit chuck is The end extends toward the direction of the swing bar. It has a reasonable structure and is easy to use. It also facilitates nursing staff to transfer patients while ensuring the patient's safety.

Based on the retrieval and analysis of existing technologies, it can be concluded that there are still deficiencies in the existing technologies:

1. The handrail in the prior art is a hollow folding guardrail connection structure. Compared with the integral guardrail board in the guardrail structure in this application, the guardrail in the prior art may cause the rear end of the guardrail to be in contact with the guardrail during the folding process. A collision at the end of the bed caused damage to the railing;

2. The guardrails in the prior art have a folding structure. Compared with the single-board, movable and reversible structures in this application, the guardrails in the prior art are larger in size during use and may become prone to collapse during use. Enclosing most of the sides of the bed will result in the need to fold and store the guardrails when getting in and out of the bed. It is impossible to move and adjust the position according to the needs of the patient or family to adjust and fill the vacancies in the bed. The applicable range is narrow, so a A method of using an adjustable folding armrest structure improves the above shortcomings.
