ABSTRACT:
A conventionally constructed baby walker 5 having a lower support member 6 to which are attached front wheels 10 and 11 (not shown) and rear wheels and 12 and 13 (not shown) in contact with floor surface 14 has further magnetically activated brake assembly 21 moveably attached to support member 6, the bottom surface of which is also in contact with floor surface 14. Brake assembly 21 further contains a permanent magnet disposed above surface 14 and attached to an internal latching mechanism. A magnetically permeable arc shaped strip 15 is further attached to floor surface 14 using conventional screws 19. Preferably strip 15 is placed in front of staircase 20 or other level drop such as may be encountered with a patio or porch. As walker 5 is propelled across surface 14 and over strip 15, the permanent magnet is downwardly attracted to the permeable strip releasing the latching mechanism and engaging brake assembly 21. With brake assembly 21 engaged, the frictional contact between surface 14 and the bottom surface of brake assembly 21 is forceably increased arresting walker 5. An audible alarm contained within brake assembly 21 is additionally energized alerting attending personnel.
