Shock Absorbing Retractable Bollard Systems

A barrier system comprising:

• a handrail, the handrail having an end with a width measured in a direction transverse to an elongate length of the handrail;
• a connector to couple the handrail to a post, the connector including a socket to hold the end of the handrail, the socket defined by an elongate channel that extends, between first and second ends of the channel, in a direction substantially parallel to the post when the connector is attached to the post, the end of the handrail to be inserted into the channel through the first end of the channel;
• and
• a retainer to selectively extend into a side of the channel to restrict movement of the end of the handrail along the channel.

A barrier system comprising:

• a connector to attach to a post, the connector defining a channel that extends along the post when the connector is attached to the post, the channel having a c-shaped cross-section based on an opening extending along the channel, the opening to face away from the post;
• a handrail having an end to be supported within the channel, the end larger than a width of the opening;
• and
• a retainer carried by the connector, the retainer extending in a direction transverse to the channel, a side of an elongate length of the retainer to extend into the channel to block the end of the handrail from moving along the channel past the retainer.

A barrier system comprising:

• a connector to attach to a post, the connector including an elongate socket and a plate at a first end of the elongate socket;
• a handrail having an end to be supported within the elongate socket, the end of the handrail to rest upon the plate, the handrail to extend through a slot that extends along a length of the elongate socket;
• and
• a retainer selectively moveable between a first position and a second position, a first end of the retainer to remain on a first side of the connector as the retainer moves between the first and second positions, a second end of the retainer to remain on a second side of the connector as the retainer moves between the first and second positions, the second side opposite the first side, a portion of the retainer to extend into the elongate socket when the retainer is in the first position to restrict movement of the end of the handrail in the elongate socket in a direction away from the plate.
