Brake assembly with an over running gear for an architectural structure covering

A brake assembly for use in an architectural-structure covering, the architectural-structure covering including a rotatable member and a covering movable between a retracted position and an extended position, the brake assembly being arranged and configured to couple to the rotatable member, the brake assembly arranged and configured to permit rotation of the rotatable member in a first direction and to inhibit rotation of the rotatable member in an opposite direction relative to the first direction to maintain a position of the covering, the brake assembly comprising:

• a housing including a receptacle formed therein and a projection extending into the receptacle;
• a hub arranged and configured to be non-rotatably coupled to the rotatable member so that the rotatable member and the hub rotate in unison;
• a drum including a gear;
• a wrap spring configured to operatively couple the hub and the drum;
• and
• a one-way gear operatively associated with the gear of the drum, the one-way gear positioned within the receptacle of the housing;
• wherein:
• in the first direction, the one-way gear is disengaged relative to the projection of the housing;
• in the opposite direction, the one-way gear is engaged with the projection of the housing, the one-way gear being free-floating within the receptacle of the housing so that the one-way gear moves into engagement with the projection under an influence of gravity;
• rotation in the first direction causes the hub to rotate the wrap spring, which rotates the drum and the one-way gear so that the hub, the wrap spring, the drum, and the one-way gear rotate in unison;
• and
• rotation in the opposite direction causes the hub to rotate the wrap spring, with the one-way gear engaged with the projection, the drum can slip relative to the wrap spring so that rotation of the hub is no longer transferred to the drum.
