  • Patent number: 4695085
    Abstract: A hand held sheet carrier for use with plywood and wallboard sheets has a pair of rigid plate components that are pivotally interconnected. One plate component has an upright working position, a foot portion on which a sheet being carried is supported and a channel for receiving the lower edge of a sheet being carried on the carrier. The second plate component is pivotally moveable between a retracted position and an extended position and has a handle. It also has a foot provider which is offset from the foot portion of the one plate component when the second plate component is in the retracted position and which serves with the foot portion to retain the one plate component in its upright position on a supporting surface for the carrier. The arrangement facilitates the loading of the carrier with a sheet to be carried by the carrier. Provision is also made for a locking device for locking the plate components in the retracted position.
