Attached armrest for rollators

Abstract

Mobile armrest / arm support for rollators, characterized in that the fastening parts, according to drawing no. 2, are pushed onto the handles of a rollator until they stop and are aligned.

Description

[0001] The invention is a mobile armrest with a handle for rollators.

[0002] This foam-padded armrest with handle is designed to support people with walking disabilities, allowing them to walk upright without straining their backs. The foam-padded armrest can be easily attached or removed, or attached to the side of the rollator, allowing for a sitting position at any time. A handle is attached to the armrest facing the direction of travel, allowing the rollator to be easily steered while supporting both arms. The armrest is attached in front of the rollator handles in such a way that the handles of a traditional rollator with brakes underneath are not obstructed. This allows the user to easily change their grip when using the rollator handles.

[0003] Existing rollators, with their classic handles, cause considerable pain when used by people with mobility disabilities, placing enormous strain on their shoulders when supported during extended use. The result is that they walk bent far forward with a hunched back, exerting enormous effort. Over the course of months / years of use, the walking aid, the rollator, becomes a mobile seat, allowing older people in particular to move around using their feet. Constant sitting and walking causes back and leg muscles to atrophy, the cardiovascular system isn't trained, and mobility gradually declines until they eventually have to use a wheelchair.

[0004] There are rollators with padded armrests, where the brakes are attached to the front of the armrest. However, these supports do not relieve the strain on the back; considerable forces are exerted on the arms and shoulders when walking. Furthermore, steering the rollator with these armrests is very difficult for older people, which is why these rollators are rarely requested by elderly people with walking disabilities. There are also rollators designed as "walkers," where the arms rest completely on the support. These "walking frames" are also rarely used, as they are not suitable for outdoor use and do not offer any seating. They are large and compact, making them very unwieldy even in spacious apartments.
