Abstract A mobile truck has a plurality of tire trays pivotally mounted thereon for movement between a generally horizontal position and a raised position. Each tray has a flared skirt at each side, a rolled edge at the rear to provide a hinge connection, and a formed flange member at the front. The flange member has a rolled edge at the bottom, and a diagonal bracket is shaped to engage the rolled edge.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
218 words
A tire tray for use on a truck for transporting tire treads and having a plurality of tire trays swingably mounted on a support for movement between a lower, generally horizontal position and a raised position, the tire tray comprising: a top wall having a smooth upper surface for receiving the tire tread thereon; a depending and outwardly flaring skirt portion at each lateral side edge of the top wall to reinforce the same; means at the rear edge of the top wall for providing a hinge connection to the support; a formed flange member at the front edge of the top wall to support the top wall and provide a leg for engaging the subjacent tire tray in the lower position; the formed flange member having an upper member underlying the top wall and attached thereto, and a depending front member having a rearwardly rolled edge at its lower end to present a smooth surface for engaging the subjacent tire tray; and a diagonal bracket having a body portion extending between the rolled edge and the underside of the tire tray, and the bracket also having a lower arcuate portion shaped complementary to and engaging the rolled edge whereby the bracket is supported thereon without the necessity of additional fastening means between the bracket and rolled edge.
Claim 2
Dependent Claim
218 words
A tire tray for use on a truck for transporting tire treads and having a plurality of tire trays swingably mounted on a support for movement between a lower, generally horizontal position and a raised position, the tire tray comprising: a top wall having a smooth upper surface for receiving the tire tread thereon; a depending and outwardly flaring skirt portion at each lateral side edge of the top wall to reinforce the same; means at the rear edge of the top wall for providing a hinge connection to the support; a formed flange member at the front edge of the top wall to support the top wall and provide a leg for engaging the subjacent tire tray in the lower position; the formed flange member having an upper member underlying the top wall and attached thereto, and a depending front member having a rearwardly rolled edge at its lower end to present a smooth surface for engaging the subjacent tire tray; and a diagonal bracket having a body portion extending between the rolled edge and the underside of the tire tray, and the bracket also having a lower arcuate portion shaped complementary to and engaging the rolled edge whereby the bracket is supported thereon without the necessity of additional fastening means between the bracket and rolled edge.
Claim 3
Dependent Claim
73 words
A tire tray as set forth in claim 1 wherein the means for providing a hinge connection to the support comprises a rear member extending along substantially the entire rear edge of the top wall and having a front portion secured to top wall and a rear portion with a rolled edge, and a hinge pin at least partially surrounded by the rolled edge of the rear member and mounted on the support.
Claim 4
Dependent Claim
56 words
A tire tray as set forth in claim 1 wherein the rolled edge of the formed flange member has an arcuate outer surface; and wherein the lower portion of the bracket is laterally offset from the body portion and has an arcuate surface complementary to the outer surface of the formed flange member and contiguous thereto.
Claim 5
Dependent Claim
31 words
A tire tray as set forth in claim 3 wherein the body portion of the bracket is generally tangential to the arcuate surface of the rolled edge of the flange member.
Claim 6
Dependent Claim
206 words
A tire tray for use on a truck for transporting tire treads and having a plurality of tire trays swingably mounted thereon, the tire tray comprising: a top wall having an upper surface for supporting the tire tread thereon; means at the rear edge of the top wall for providing a hinge connection to the truck; a formed flange member at the front edge of the top wall to rigidify the same and provide a leg for engaging the subjacent tire tray; the formed flange member having an upper member underlying the front edge of the top wall and secured thereto, and a depending front member at about a right angle to the upper member and having a rearwardly rolled edge at its lower end; a bracket having a body portion generally tangential to the rolled edge and extending therefrom to the upper member; the bracket also having an arcuate portion offset upwardly from the body and shaped complementary to the rolled edge of the flange member thereby supporting the bracket thereon; and means securing the upper end of the body portion of the bracket to the upper member of the flange member; whereby said last-mentioned means and the arcuate portion hold the bracket in position.
Claim 7
Dependent Claim
206 words
A tire tray for use on a truck for transporting tire treads and having a plurality of tire trays swingably mounted thereon, the tire tray comprising: a top wall having an upper surface for supporting the tire tread thereon; means at the rear edge of the top wall for providing a hinge connection to the truck; a formed flange member at the front edge of the top wall to rigidify the same and provide a leg for engaging the subjacent tire tray; the formed flange member having an upper member underlying the front edge of the top wall and secured thereto, and a depending front member at about a right angle to the upper member and having a rearwardly rolled edge at its lower end; a bracket having a body portion generally tangential to the rolled edge and extending therefrom to the upper member; the bracket also having an arcuate portion offset upwardly from the body and shaped complementary to the rolled edge of the flange member thereby supporting the bracket thereon; and means securing the upper end of the body portion of the bracket to the upper member of the flange member; whereby said last-mentioned means and the arcuate portion hold the bracket in position.
Claim 8
