Patent ID: 8678699

Claim:
A connection system comprising: a U-shaped frame member having elongate arms; an items selectively attachable with the U-shaped frame member; the items comprising a base member, the base member comprising at least two opposed toggle clamps for releasably engaging the elongate arms of the U-shaped frame member, at least two corresponding resilient stops, each comprising a section of the item which can flex to allow for rotation of the toggle clamps and which is flush with a top surface of the item in a non-flexed position and at least one toe with a curved distal end shaped to receive an interior of a bend of the U-shaped member, and to prevent forward or reverse movement of the item with respect to the U-shaped member, which releasably engages the bend of the U-shaped frame member, wherein the item is provided on a first side of the U-shaped frame member and the toe contacts a second opposing side of the U-shaped frame member wherein each of the toggle clamps are rotatable between an open configuration in which a toggle clamp is rotated against a corresponding resilient stop and a closed configuration in which the U-shaped frame member has passed a predetermined point of rotation of the toggle clamp against the resilient stop by moving the U-shaped frame member towards the toggle clamp; and wherein after a deformation of the resilient stops, the at least two toggle clamps resume a stop position to prevent reverse rotation and thereby capture the U-shaped frame member.
