ABSTRACT:
An improved sheet carrying device in which a frame is provided including a lower frame portion defining a plane against which a sheet of material may be placed. The lower frame portion has a lower crossbar which forms a lower lifting region and defines a curve which is effective for accommodating a leg of a user during use to facilitate walking. An upper frame portion has an upper crossbar which forms an upper lifting region and defines a curve which is effective for accommodating the shoulder of the user during use to prevent sliding of the carrying device. The lower frame portion includes a pair of extendable arms which are effective for varying the distance between the upper lifting region and the lower lifting region. A strap member is attached to the upper frame portion which is effective for supporting the carrying device around the torso of a user during use. To more securely grip a sheet of material having a smooth surface, such as glass, an embodiment of the present invention includes a planar member which is disposed in the plane against which the sheet of material is placed. The planar member has a sheet contacting surface which is effective for contacting with the surface of the sheet placed in the plane to thereby provide larger surface contact area between the inventive carrying device and the sheet being carried. At least two pairs of cams which are pivotally supported on mounting arms disposed opposite the plane against which the sheet of material is placed are effective to engage with the sheet of material.
