Abstract

Abstract An improved device for securing stacks of large glass sheets for over-the-road movement is disclosed. The device includes a main truck trailer frame providing a floor and generally vertical central support for one or more large sheets in generally vertical position. A fixed guide bar extends the length of the frame behind the central support and laterally extending rails are removably secured to the guide bar adjacent the opposed vertical edges of the sheet. A longitudinal rail is adjustably secured to the outer ends of the lateral rails to extend across the outer face of the sheets and means are provided to draw both the lateral and longitudinal rails against the glass sheets to hold it securely against movement. An especially designed bracket is used to secure the lateral rails to the fixed guide bar and longitudinal rail to also provide for vertical adjustment of the height of the lateral and longitudinal rails to accommodate various sized glass sheets.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 173 words
In a device for transporting large planar sheets of rigid material in a generally vertical position including a fixed generally vertical support adjacent the inner face of such planar sheets, the improvement comprising a horizontal guide extending longitudinally of such transporting device behind said fixed support, at least one lateral rail slidably and removably positioned upon said horizontal guide and extending laterally outwardly alongside the vertical edges of such planar sheets, winch means for moving said lateral rail along said horizontal guide and into engagement with the vertical edges of such planar sheets and for maintaining said lateral rail in such engagement, thereby restraining such sheets from longitudinal movement, a longitudinal rail slidably positioned on the outer end of said lateral rail and extending across the outer face of such planar sheets and means independent of said winch means for moving said longitudinal rail against the outer face of such planar sheets and for holding it there, thereby restraining such sheets from lateral movement, whereby such sheets are restrained against movement during transport.
Claim 2
Dependent Claim 173 words
In a device for transporting large planar sheets of rigid material in a generally vertical position including a fixed generally vertical support adjacent the inner face of such planar sheets, the improvement comprising a horizontal guide extending longitudinally of such transporting device behind said fixed support, at least one lateral rail slidably and removably positioned upon said horizontal guide and extending laterally outwardly alongside the vertical edges of such planar sheets, winch means for moving said lateral rail along said horizontal guide and into engagement with the vertical edges of such planar sheets and for maintaining said lateral rail in such engagement, thereby restraining such sheets from longitudinal movement, a longitudinal rail slidably positioned on the outer end of said lateral rail and extending across the outer face of such planar sheets and means independent of said winch means for moving said longitudinal rail against the outer face of such planar sheets and for holding it there, thereby restraining such sheets from lateral movement, whereby such sheets are restrained against movement during transport.
Claim 3
Dependent Claim 73 words
The device of claim 1 wherein said longitudinal rail is slideably supported on said lateral rail by a connector bracket, said bracket having a first bearing opening complementarily shaped to slide over said lateral rail and a second bearing opening positioned at right angles and closely adjacent below said first bearing opening and complementarily shaped to slide over said longitudinal rail to thus position said longitudinal and lateral rails normal to one another.
Claim 4
Dependent Claim 33 words
The device of claim 2 wherein one of said bearing openings is comprised of releasable portions which may be opened to receive its complementarily shaped rail and then secured together upon said rail.
Claim 5
Dependent Claim 20 words
The device of claim 2 wherein one of said bearing openings and its complementarily shaped rail are non-circular in cross-section.
Claim 6
Dependent Claim 208 words
In a device for transporting large planar sheets of rigid material in a generally vertical position including a fixed longitudinal central support having generally vertical outer faces to support on either side the inner face of a stack of such planar sheets, the improvement comprising at least one fixed horizontal guide extending longitudinally of such transport device within such fixed central support between the opposed outer faces thereof, at least one lateral rail slidably and removably positioned upon said horizontal guide and extending laterally outwardly alongside the vertical edges of such planar sheets on each side of said central support, cable means for moving said lateral rail along said horizontal guide and into engagement with the vertical edges of such planar sheets and for holding it there to retain such sheets against longitudinal movement, a longitudinal rail slidably positioned on the outer ends of said lateral rail and extending across the lateral faces of such stacks of planar sheets on each side of said central wall and means independent of said first recited means for moving said longitudinal rail against the outer face of such planar sheets and for holding it there, thereby restraining such sheets from lateral movement, whereby such sheets are restrained against movement during transport.
Claim 7
Dependent Claim 208 words
In a device for transporting large planar sheets of rigid material in a generally vertical position including a fixed longitudinal central support having generally vertical outer faces to support on either side the inner face of a stack of such planar sheets, the improvement comprising at least one fixed horizontal guide extending longitudinally of such transport device within such fixed central support between the opposed outer faces thereof, at least one lateral rail slidably and removably positioned upon said horizontal guide and extending laterally outwardly alongside the vertical edges of such planar sheets on each side of said central support, cable means for moving said lateral rail along said horizontal guide and into engagement with the vertical edges of such planar sheets and for holding it there to retain such sheets against longitudinal movement, a longitudinal rail slidably positioned on the outer ends of said lateral rail and extending across the lateral faces of such stacks of planar sheets on each side of said central wall and means independent of said first recited means for moving said longitudinal rail against the outer face of such planar sheets and for holding it there, thereby restraining such sheets from lateral movement, whereby such sheets are restrained against movement during transport.
Claim 8
Dependent Claim 73 words
The device of claim 5 wherein said longitudinal rails are slideably supported on said lateral rail by a connector bracket, said bracket having a first bearing opening complementarily shaped to slide over said lateral rail and a second bearing opening positioned at right angles and closely adjacent below said first bearing opening and complementarily shaped to slide over said longitudinal rail to thus position said longitudinal and lateral rails normal to one another.
Claim 9
Dependent Claim 32 words
The device of claim 6 wherein one of said bearing openings is comprised of releasable portions which may be opened to receive its complementarily-shaped rail and then secured together upon said rail.
Claim 10
Dependent Claim 20 words
The device of claim 6 wherein one of said bearing openings and its complementarily shaped rail are non-circular in cross-section.
