COLLAPSIBLE HARD-SIDED COOLER

TECHNICAL FIELD

The present disclosure relates generally to coolers, and more particularly, to a collapsible hard-sided cooler.

BACKGROUND

Coolers, ice chests, ice boxes, or the like are commonly used to store contents (e.g., food, beverages, etc.) and keep the contents cool. Some coolers are hard-sided and may provide the performance and durability desired by a user. However, because hard-sided coolers are typically rigid, such coolers tend to take up more space than desired the coolers are not in use. Such hard-sided coolers can be inconvenient to store and to transport when not in use. While soft-sided coolers are collapsible, and thus, and may be convenient to store and transport, soft-sided coolers may lack the performance and durability that may be desired by a user. Thus, a hard-sided cooler that is collapsible into a smaller size may be desirable.

In some alternative embodiments, the end panel 106 may include a single attachment tab or more than two attachment tabs for attaching the panel 106 to the frame 110. In some alternative embodiments, the end panel 106 may be attached to the frame 110 in a similar manner as the upper front panel 112 is attached to the frame 110.

In some example embodiments, the end panels 106, 206 are in contact with the base 108 when the cooler 100 is un-collapsed as shown in FIGS. 1-4. For example, the end panel 106 may be rotated with respect to the frame 110 to a vertical position as shown in FIGS. 1 and 4 and held in place by friction between the end panel 106 and the base 110. The end panel 206 may be rotated with respect to the frame 110 to a vertical position as shown in FIGS. 1, 2, and 4 and held in place by friction between the end panel 106 and the base 108. To rotate the end panels 106, 206 toward the cavity 402, a person may push each panel 106, 206 inward with enough force to overcome the friction between the end panel 106, 206 and the base 108.

In some example embodiments, the upper front panel 112, the lower front panel 114, the upper back panel 202, the lower back panel 204, and the end panel 106, 206 define the cavity 402 of the cooler body 102 when the cooler 100 is un-collapsed as shown in FIGS. 1-4. When the liner 200 is inserted in the cavity 402 of the cooler body 102, a perimeter 416 of the liner 200 may snap on to the frame 110 retaining the liner 200 in the cavity 402 while allowing the lid 104 to fully cover the cavity 402 when the lid 104 is closed as more clearly shown in FIG. 1.

In some example embodiments, the strap 124 may be made from a fabric or another suitable material as can be readily understood by those of ordinary skill in the art with the benefit of this disclosure. In some example embodiments, the base 108 and the frame 110 may be made from polyurethane and/or polyethylene or from another suitable material as can be readily understood by those of ordinary skill in the art with the benefit of this disclosure. The base 108 and the frame 110 may be made using blow molding or injection molding methods. In some example embodiments, the panels 110, 114, 202, 204, 106, 206 may be made from polyurethane and/or from another suitable material as can be readily understood by those of ordinary skill in the art with the benefit of this disclosure. The panels 110, 114, 202, 204, 106, 206 may be made using blow molding and may be foamed or air filled.

FIG. 5 shows the hard-sided collapsible cooler 100 of FIG. 1 partially collapsed according to an example embodiment, and FIG. 6 shows the hard-sided collapsible cooler 100 of FIG. 1 fully collapsed according to an example embodiment. Referring to FIS. 1-6, in some example embodiments, the cooler 100 may be fully collapsed as shown in FIG. 6. For example, starting from the un-collapsed configuration shown in FIGS. 1 and 2, a person may rotate the end panels 106, 206 inward toward each other by pushing on the panels 106, 206 closer to the base 108 than the frame 110. The end panels 106, 206 remain attached to the frame 110 as the end panels 106, 206 are rotated. Each end panel 106, 206 may be rotated to a substantially horizontal position below the lid 104. For example, the end panels 106, 206 may be rotated into a horizontal plane that is substantially perpendicular to the un-collapsed positions of the end panels 106, 206. When the end panels 106, 206 are being rotated inward to collapse the cooler 100, the end panels 106, 206 may the liner 200 push inward and upward such that the liner 200 becomes positioned between the end panels 106, 206 and the lid 104.

In some example embodiments, after rotating the end panels 106, 206 inward such that the end panels 106, 206 are substantially in horizontal positions, the user may collapse the upper front panel 112 and the lower front panel 114 as well as the upper back panel 202 and the lower back panel 204, for example, by pushing the panels inward. For example, the user may collapse the upper front panel 112 and the lower front panel 114 by pushing inward on the upper front panel 112 and/or the lower front panel 114 close to attachment sections of the upper front panel 112 and/or the lower front panel 114. The user may collapse the upper back panel 202 and the lower back panel 204 by pushing inward on the upper back panel 202 and/or the lower back panel 204 close to attachment sections of the upper back panel 202 and the lower back panel 204.

In some example embodiments, the upper front panel 112 may remain attached to the frame 110 and to the lower front panel 114 while the cooler 100 is being collapsed and after the cooler 100 is collapsed. The upper back panel 202 may remain attached to the frame 110 and to the lower back panel 204 while the cooler 100 is being collapsed and after the cooler 100 is collapsed. The lower front panel 114 may remain attached to the base 108 and to the upper front panel 112 while the cooler 100 is being collapsed and after the cooler 100 is collapsed. The lower back panel 204 may remain attached to the base 108 and to the upper back panel 202 while the cooler 100 is being collapsed and after the cooler 100 is collapsed. The cooler 100 may be transformed from the partially collapsed configuration shown in FIG. 5 to the fully collapsed configuration shown in FIG. 6 by pushing down on the lid 104 of the cooler 100.

In some example embodiments, the steps of collapsing the cooler 100 may be performed in the reverse order to un-collapse the cooler 100 from the collapsed configuration shown in FIG. 6. For example, lid 104 may be pulled upward, and the upper front panel 112 and the lower front panel 114 as well as the upper back panel 202 and the lower back panel 204 may be stretched out to the vertical positions shown in FIGS. 1 and 2. The end panels 106, 206 may be rotated out until the end panels 106, 206 are stopped by the base 110 at the vertical positions of the end panels 106, 206 shown in FIGS. 1 and 2.

By using the base 108 as well as the panels 106, 206, 112, 114, 202, 204 that serve as hard-sided walls, the hard-sided collapsible cooler 100 can provide the performance and durability of a hard-side cooler while providing the collapsibility of a soft-side cooler. In some example embodiments, the height of the collapsed hard-sided collapsible cooler 100 as shown in FIG. 6 may be less than 50 percent the height of the un-collapsed hard-sided collapsible cooler 100 as shown in FIG. 1.

FIG. 7 shows a stack of multiple hard-sided collapsible coolers 702-706 that are fully collapsed according to an example embodiment. Referring to FIGS. 1-7, in some example embodiments, each cooler of the hard-sided collapsible coolers 702-706 may correspond to the hard-sided collapsible cooler 100 that is in a fully collapsed configuration in FIG. 6. The hard-sided collapsible cooler 100 may be designed to be stackable as shown with respect to the hard-sided collapsible coolers 702-706. The collapsibility of the hard-sided collapsible coolers 702-706 may result in significant space saving during storage and transportation of the hard-sided collapsible coolers 702-706.

Referring to FIGS. 9-11, in some example embodiments, a panel 902 may include an attachment section 906 that includes a hole that extends through a portion or the entire length of the attachment section 906. A panel 904 may include attachment sections 910, 912 that each have a respective hole 918 or 920.

In some example embodiments, to rotatably attach the panel 902 to the panel 904, the attachment section 906 may be placed in a space 914 between the attachment sections 910, 912, and the rod 1000 or the rod 1100 may be inserted and extended through holes 920, 908, 918 as well as a hole at an opposite end of the attachment section 906 from the hole 908. Alternatively, one rod 1000 or 1100 may be inserted through the hole 920 and the hole 908 to extend partially into the attachment section 906 and another rod 1000 or 1100 may be inserted through the attachment structure 910 such that the rod extends entirely through attachment structure 910 and partially through the attachment section 906.

In general, the rod-based attachment mechanism described with respect FIGS. 9-11 may be used to attach the panels of the cooler 800 to the base 108, the frame 110, and/or to each other.

FIGS. 12A-12C show different views of a hard-sided collapsible cooler 1200 according to another example embodiment. In some example embodiments, the cooler 1200 is substantially similar to the coolers 100, 800. FIG. 12A shows the cooler 1200 un-collapsed and with a closed lid, FIG. 12B shows the cooler 1200 un-collapsed and with an open lid, and FIG. 12C shows the cooler 1200 collapsed. In some example embodiments, the cooler 1200 includes a cooler body 1202, a lid 1204, and a frame 1206. The cooler 1200 may also include a base 1214 and multiple panels that respectively correspond to the base 108 and panels of the cooler 100, 800. In general, the panels of the cooler 1200 may be attached to the frame 1206 and/or to the base 1214 in the same manner as the panels of the cooler 100, 800 are attached to the frame 110 and/or the base 108 of the cooler 100, 800.

In contrast to the frame 110 of the cooler 100, the frame 1206 of the cooler 1200 may extend down further relative to the panels such that the attachment areas between the panels and the frame 1206 are hidden from view by the frame 1206. Further, in contrast to the handle 122 of the cooler 100, a handle 1208 of the cooler 1200 is rotatably attached directly to the frame 1206 on opposite sides of the cooler 1200. For example, a first end portion 1210 of the handle 1208 may be attached to the frame 1206 on one side of the frame 1206, and a second end portion 1212 of the handle 1208 may be attached to the frame 1206 on an opposite side of the frame 1206 such that the handle 1208 can extend over and across the lid 1204. The handle 1208 may include one or more slots 1216.

In some example embodiments, the handle 1208 may be rotated to a position such that the handle 1208 is flush or below the frame 1206 as shown in FIGS. 12B and 12C. For example, the handle 1208 may be positioned on a ledge 1222 of the frame 1206 to open the lid 1204 or to stack multiple hard-sided collapsible coolers 1200 in a similar manner as shown in FIG. 7. In general, the handle 1208 enables a person to carry the cooler 1200 with one hand and to conveniently move the handle to 1208 to open the lid 1204 or to stack up multiple coolers. The hard-sided collapsible cooler 1200 can provide the performance and durability of a hard-side cooler while providing the collapsibility of a soft-side cooler to save storage space.
