Abstract
A wheeled shipping/transport cart includes a cart frame that supports a plurality of wheels. The cart frame supports a plurality of stackable trays. The trays include a tray frame with opposed end members, a plurality of longitudinal support members disposed between the opposed end members, and a plurality of upright members nesting with upright members of an adjacent tray. A support structure is disposed between the opposed end members to form an arc corresponding to a curved surface of an article to be supported by the support structure. A pin is received through each of the upright members of the plurality of stackable trays to retain the stackable trays in a stacked configuration.
Claims23
An apparatus, comprising:
- a cart frame;
- a plurality of stackable trays supported by said cart frame, each stackable tray comprising:
- a tray frame comprising opposed end members, a plurality of longitudinal perimeter members disposed between the opposed end members, and a plurality of upright members nesting with upright members of an adjacent tray;
- and
- a support structure disposed between the opposed end members, the support structure comprising an arcuate upper support surface corresponding to a curved bottom surface of an article to be supported by the support structure, the support structure further comprising a plurality of longitudinal support members each forming an upper surface, the longitudinal support members disposed between the opposed end members in an arced arrangement such that the upper surfaces of the longitudinal support members are in contact with and support an underside of the arcuate upper support surface that supports the curved bottom surface of the article, wherein at least one of the longitudinal support members is positioned above other longitudinal support members to define the arced arrangement;
- and
- a plurality of pins each received through the upright members of the plurality of stackable trays to retain the stackable trays in a stacked configuration.

A shipping cart, comprising:
- a first tray comprising a first tray frame comprising first opposed end members, a plurality of first longitudinal perimeter members disposed between the first opposed end members, and a plurality of first upright members disposed at each corner of the first tray frame, each first upright member defining a first female end and a first male end, the first tray further comprising a first support structure disposed between the first opposed end members, the first support structure comprising a first support surface that is convex upward, the first support surface corresponds to a concave downward bottom surface of an article, the first support structure further comprising a plurality of first longitudinal support members disposed between the first opposed end members, the first longitudinal support members positioned adjacent to each other in a convex upward arced arrangement to support the first support surface;
- a second tray comprising a second tray frame comprising second opposed end members, a plurality of second longitudinal perimeter members disposed between the second opposed end members, and a plurality of second upright members disposed at each corner of the second tray frame, each second upright member defining a second female end and a second male end, the second tray further comprising a second support structure disposed between the second opposed end members, the second support structure comprising a second support surface that is convex upward, the second support surface corresponds to the concave downward bottom surface of the article, the second support structure further comprising a plurality of second longitudinal support members disposed between the second opposed end members, the second longitudinal support members positioned adjacent to each other in a convex upward arced arrangement to support the second support surface;
- a plurality of pins each pin received in pin holes to secure the second male ends of the second tray in the first female ends of the first tray and secure the first tray in a stacked configuration with the second tray, the first tray being vertically spaced apart from the second tray to accommodate the article supported by the second tray;
- a cart supporting a plurality of wheels and comprising a cart frame and cart upright members disposed at corners of the cart frame, the cart upright members having cart male ends received in the second female ends of the second tray;
- and
- a second plurality of pins securing the second tray to the cart upright members to secure the first and second trays in a stacked configuration with the cart.
