ABSTRACT:
A device for locking down a wheelchair or like device having a wheel supported frame structure to a support structure having a fixed eyelet mounted thereon. The lockdown device includes an elongated assembly adjustable as to length and with spaced surfaces thereon for engaging and embracing spaced frame members on a wheelchair, and apparatus for applying force on the elongated assembly when engaged with wheelchair frame members to lock the wheelchair to the support structure. The apparatus is mounted transversely with respect to the elongated assembly and includes a hook member extendible through the elongated assembly having a hook portion on one end for cooperatively engaging the fixed eyelet and a cam member pivotally mounted thereon for engaging a cam follower on the elongated member, the cam member being movable relative to the cam follower to change the extended position of the hook portion relative to the elongated assembly and to simultaneously exert force on the elongated assembly against the wheelchair frame members engaged therewith. The device also includes an adjustment member threadedly engageable with the hook member to adjust the position of the hook member relative to the elongated assembly.
