In some embodiments, the bracing member 52, the first engaging member 55, and the second engaging member 53 can be the same length extending from the base 51. In other embodiments, one or more of the bracing member 52, the first engaging member 55, and the second engaging member 53 can have different lengths. For example, the first and second engaging members 55, 56 can have a greater length than the bracing member 52, or the bracing member 52 can have a greater length than the engaging members 55, 56.

The latch 50 in the latched position can be substantially flush with the door 40, the sidewall 21, or both, as shown in FIGS. 11 and 12. With respect to the sidewall 21, the latch 50 in the latched position can be substantially flush with the sidewall lips 21f, 21b. For example, the latch 50 can extend past the outer face of the door 40 and/or the outer side of the sidewall 21 by about 1 inch or less, about ½ inch or less, about ¼ inch or less, or about ⅛ inch or less. In other examples, the latch 50 in the latched position does not extend past the sidewall lips 21f, 21b.

The storage and transport cart 10 can be configured to carry food products, such as bakery goods. In some embodiments as shown in FIG. 20, the interior compartment 30 includes a plurality of horizontal supports 31 for receiving one or more trays in the compartment 30. The horizontal supports 31 can be attached to an inner face of the first sidewall 21 and the second sidewall 22, allowing a plurality of trays to be removably inserted and supported in the cart 10. The supports 31 can spaced apart longitudinally on the sidewalls 21, 22 to accommodate common sizes of products. The interior compartment 30 can be divided into sections, e.g. upper, middle and lower sections, and different sections can have different spacings to accommodate more than one type of product. For example, the supports 31 can be spaced apart by a first distance in a first section and a second distance different from the first distance in a second section. Spacing can be selected from the distances 3 9/15 inches apart and 2⅛ inches apart. In some embodiments, horizontal supports 31 can be formed with substantially C-shaped inserts 35 attached to an inner face of the sidewalls 21, 22. As shown in FIG. 20A, the insert 35 can include a back 36 and two spaced apart supports 31, 31. The back 36 of the insert 35 can be mounted to the sidewalls 21, 22.

In some embodiments as shown in FIG. 1, the plurality of handles 80 includes two laterally spaced apart lower handles 81, 82 and one upper handle 83. The lower handles 81, 82 can be disposed on a middle portion or a lower portion of a sidewall 21, 22 and can facilitate lateral movement of the cart 10, such as by pushing or puffing. In some embodiments, the upper handle 83 can be disposed on an upper portion of a sidewall above and between the lower handles 81, 82. The upper handle 83 can facilitate tilting of the cart 10 or other maneuvering during loading/unloading from a container or vehicle.

As shown in FIG. 21, the handles 80 can also be substantially flush with the sidewall 21, 22 to which it is attached. For example, each handle can be pivotably attached to the sidewall (e.g. the first sidewall 21) and, in a resting position, rest against the sidewall 21. The handle 80 can have a thickness of 1″ or less, ¾″ or less, ⅔″ or less, ½″ or less, or ¼ or less, such that in the resting position the handle 80 would only slightly extend past the sidewall. In embodiments having a sidewall with lips 21f, 21b, the handle 80 in the resting position can rest against the sidewall 21 without extending past the sidewall lips 21f, 21b. For example, the sidewall lips 21f, 21b can form an outer plane of the sidewall 21 or the sidewall lips 21f, 21b together with the handles 80 in the resting position can form the outer plane of the sidewall 21.

The storage and transport cart 10 can also include a viewing panel 90 attached to one of the walls 20 of the holding body 15. As shown in FIGS. 1 and 2, the viewing panel 90 can be a relatively clear plate for removable insertion of a label to identify the products stored within a cart 10. The plate 90 can include a plastic, an acrylic plastic, or similar material in a thickness of about 1/16 to ⅛ inch. The plate 90 can be attached to a wall 20 with washers and rivets, adhesives, or other suitable fasteners. In one example, the washers can be zinc plated and the rivets can be aluminum. In another example, the washers and rivets can be stainless steel.

The cart 10 and the latch 50 described herein provide numerous advantages in the storage and transport of products and especially fragile or sensitive products such as baked goods. The cart 10 is reinforced in numerous areas to significantly improve durability, while also providing a highly maneuverable and efficient design for loading and unloading from a shipping container or vehicle. Additionally, the unique configuration provides a sleek and efficient ent cart 10 for optimized packing into a cargo container or vehicle and minimizing protrusions that may prevent tighter packing of carts or that may damage adjacently packed carts during transport. The overall size of the carts 10 can also be adapted for specific types of containers. For example, the cart 10 can be sized about 28⅝ to 28 5/16 inches wide along the front and back, about 27⅞ to 28 5/16 inches wide along the sides, and about 72⅞ inches tall for a standard semi-truck trailer.

As shown in FIG. 22, a method 100 of transporting products can include providing a plurality of storage and transport carts as described herein at step 200 and packing the carts in a container or a transport vehicle at step 300. The carts can be packed such that the outer sides of the carts fitted against each other. For example, once packed, an outer side of a first cart can be substantially flush against an outer side of a second cart, and so on, minimizing free space between carts. In some arrangements such as shown in FIGS. 23A and 23B, each of the plurality of storage and transport carts, once packed, has an outer side of the cart substantially flush against one or more of the other carts.

The packing step 200 can further include substantially filling a width of the container or storage area of the transport vehicle with the plurality of carts, substantially filling a length of the container or storage area of the transport vehicle with the plurality of carts, or both. As used herein, “substantially filling” a length or width has its plain meaning and includes filling at least a majority of the respective space. In some arrangements, substantially filling can include positioning a plurality of carts side by side such that the remaining interior space along the length and/or width of the container or storage area is less than a width of one of the carts.

In some embodiments, one or more of the storage and transport carts provided at step 200 can include a plurality of handles and wheels attached to the holding body as described above and shown in FIGS. 1-21. The packing step 300 can be performed by pulling on an upper handle of the cart to tilt the cart onto one or two of the wheels and pulling or pushing on one, two, or more of the handles to move the cart into position. Any combination of the handles can be used including, one upper handle, one lower handle, an upper and a lower handle, or two lower handles. This method utilizing carts with handles and/or wheels facilitates lateral movement of the carts for packing 200 and/or unloading carts from a container or transport vehicle.

The unique features of the storage and transport cart 10 and method 100 provide for more effective and economical packing and transportation of the carts, allowing the carts to be fitted together within a container, cargo area of a transport vehicle, or similar storage space to minimize free space between the carts 10 and/or between the plurality of carts 10 and the interior wads of the container. This advantageously optimizes the number of carts that can be packed while also reduces the movement of the carts during transport (e.g., jostling while driving) for more secure and intact delivery of the products stored in each cart. The highly maneuverable carts 10 and method 100 further provide for more efficient packing and unloading of carts 100 during transport and/or storage.

The foregoing is provided for purposes of illustrating, explaining, and describing embodiments of this invention. Modifications and adaptations to these embodiments will be apparent to those skilled in the art and may be made without departing from the scope or spirit of this invention.
