Handrail and end member assembly

The present invention relates to handrails of the type that are mounted on walls and that have end members that are installed on the exposed ends of the handrails to prevent clothing, the hands and arms of persons, and objects from being caught in an otherwise open gap between the wall and the end of the handrail. An end member is joined against axial displacement to a handrail by a lock member that is coupled to a mounting flange portion of the end member against axial movement and for rotation relative to the mounting flange portion. A locking cam portion of the lock member is received in an under cut mounting groove of the handrail and is configured to permit the lock member to be moved axially along the locking groove in an unlocked rotational position relative to the locking groove and to frictionally engage walls of the locking groove in a locked rotational position relative to the locking groove and thereby retain the end member against axial movement relative to the handrail.
