Shock absorbing retractable bollard systems

A barrier system comprising:

• a first handrail having an elongate central section extending between first and second ends;
• and
• a connector to couple the first handrail to a post extension that extends upward from a floor, the connector including an elongate channel extending in a first direction, the channel to retain the first end of the first handrail with the first handrail extending through a slot in a side of the channel to enable the first handrail to extend in a second direction transverse to the first direction, the channel having a length in the first direction sufficient to retain an end of a second handrail simultaneously with the first end of the first handrail, the first end of the first handrail to slidingly fit into an open end of the channel, the first end of the first handrail too large to fit through the slot in the side of the channel.
