ABSTRACT:
The present invention relates to a step up device which provides a large stable platform with a hand rail to give the user a safe method of elevation. Older and/or infirm people frequently experience limited movement of their limbs making it difficult to get into bed. To do this an elevation aid is often required. Current stools and step up devices for this purpose are widely available in hospitals but are cumbersome taking up much storage space and are difficult to transport from place to place for use by different patients. This invention provides an improved step-up device which reduces storage space and improves transportation. The present invention provides a large stable platform with a hand rail to provide the user with a safe method of elevation. The hand rail is foldable, and is positioned to provide stability to the platform. The top of the platform is designed with a non-slip surface and a non-skid material is fastened to the legs to provide further stability. Rolling means may be provided to aid in ease of movement of the step up platform. The rolling means are installed in such a manner that the platform must be tilted upon one edge for the rolling means to be able to engage the supporting surface thus preventing the device from accidentally rolling while in use.
