Hand rail safety bar |
(57) A stairway safety bar 10 comprises a housing 14 slidable on a rail 18 which is fixed
to a wall 20. The bar 12 extends across a stairway and may be pushed up or down the
stairway by a person ascending or descending. The housing 14 includes a locking mechanism
(22, 26) which locks on to the rail 18 thereby preventing further movement of the
bar and a force which exceeds a predetermined limit is applied to the bar. The bar
can be pushed by an elderly or disabled person, but should the person fall the additional
force applied will lock the mechanism and prevent the person falling down the stairs.
