Abstract
Official abstract text for this publication.
A locking mechanism associated with a handrail is provided. A housing having a top open end is configured to accommodate the handrail in an upright position. The housing has a side open end configured to accommodate the handrail in a collapsed position. A pair of slots is provided on opposite side surfaces of the housing. Each of the side surfaces is adjacent to the side open end. A bracket is affixed to any one of the side surface of the housing. A locking member is pivotally coupled to the bracket. The first arm of the locking member is configured to selectively engage with the pair of slots to retain the handrail in the upright position. A second arm of the locking member is configured to selectively release the first arm from the pair of slots to allow the handrail to move from the upright position to the collapsed position.
