Tool attachment system

A retention system comprising a rotatable dock and an attachment device adapted to be connected to the rotatable dock, the dock comprising:

• a retainer member comprising a retention portion adapted to be trapped by the retention system, and
• a mounting member adapted to be mounted on an object;
• the retainer member mounted on the mounting member for rotation about an axis, and
• a detent mechanism that resists relative rotation of the mounting and retaining members and
• the attachment device including:
• a first elongate slot having an open first end, the first slot adapted to receive a retention portion of the first dock via the open first end;
• a second elongate slot having an open second end, the second slot adapted to receive a retention portion of a second retainer via the open second end;
• a first latch portion and a second latch portion;
• a first release portion having a first engagement surface, and
• a second release portion having a second engagement surface,
• wherein
• the first latch portion and the second release portion are connected together for rotation about a first axis;
• the second latch portion and the first release portion are connected together for rotation about a second axis;
• the first latch portion and second release portion are connected to the second latch portion and first release portion;
• the first latch portion is rotatable about the first axis between a first retaining position and a first open position and,
• in the first retaining position
• the second engagement surface is located in the second slot at a second release position remote from the second end, and
• at least part of the first latch portion extends into or across the first slot to substantially block the slot, and
• in the open position the first slot is not blocked by the first latch portion;
• the second latch portion is rotatable about the second axis between a second retaining position and a second open position,
• and in the second retaining position,
• the first engagement surface is located in the first slot at a first release position remote from the first end, and
• at least part of the second latch portion extends into or across the second slot to substantially block the slot, and
• in the open position the slot is not blocked by the second latch portion, and
• when in the first retaining position the first latch portion is located between the first end and the first release position, and
• when in the second retaining position the second latch portion is located between the second end and the second release position, and
• movement of the first engagement surface away from the first release position and away from the first open end causes the second latch portion to move from the second retaining position toward the second open position and causes or urges movement of the first latch portion toward the first retaining position;
• movement of the second engagement surface away from the second release position and away from the second open end causes the first latch portion to move from the first retaining position toward the first open position and causes or urges movement of the second latch portion toward the second retaining position;
• and
• when one of the first and second latch portions is between the respective open and retaining positions, the other of the first and second latch portions extends into the respective first or second slot.
