<p>A hand rail assembly (10, 110) including a graspable portion (14, 114) connected at spaced portions, such as ends (15, 18), to a support wall (11) with at least one of the connections (16, 116) being breakable by inadvertent application of high force to the hand rail assembly to avoid substantial damage to the hand rail assembly by such forces. The breakable connection may include a shear pin (30) or releasable ring (143) permitting the breakable connection to be broken by such high forces but assuring the connection to be maintained by forces normally applied to the hand rail assembly in normal use. The breakable connection may be provided at one or both ends of the graspable portion. In the illustrated embodiment, the breakable connection is provided at one end with the other end being provided with a swingable connection. The connections may include brackets (28, 35) or may be defined by distal end portions (140, 148) of the studs (121, 131) connected directly to the wall portion (11). </p> |
