Claims27
A collapsible cart configured to transition from a closed condition where it is folded up to an open condition where it is expanded for use, the collapsible cart comprising:
- a rigid frame forming a compartment, the rigid frame having a front wall, a rear wall, a right sidewall, a left sidewall, and a bottom wall, the right sidewall and the left sidewall are configured to fold inwardly in the closed condition;
- the right sidewall comprising a first right panel rotatably coupled to a second right panel;
- a first track formed along the first right panel and the second right panel extending from a first position on the first right panel to a second position on the second right panel;
- and
- a first slideable member cooperatively engaged to the first track, the first slideable member is movable along the first track between an open position to a closed position to selectively lock the first right panel to the second right panel, wherein the first slideable member is in the open position when disposed along the first track adjacent the first position of the first track while not disposed along the second right panel and is in the closed position when disposed along the first track adjacent the second position of the first track while being disposed across both the first right panel and second right panel.
A collapsible cart configured to transition from a closed condition where it is folded up to an open condition where it is expanded for use, the collapsible cart comprising:
- a rigid frame forming a compartment in the open condition, the rigid frame having a front wall, a rear wall, a right sidewall, a left sidewall, and a bottom wall,
- wherein the right sidewall and the left sidewall are configured to fold inwardly in the closed condition,
- wherein the right sidewall comprises a first right panel rotatably coupled to a second right panel,
- wherein the first right panel comprises a first locking member in the open condition and the closed condition, and the second right panel comprises a second locking member in the open condition and the closed condition, and
- wherein the first locking member cooperatively engages the second locking member to selectively align the first right panel with the second right panel.
A collapsible cart configured to transition from a closed condition where it is folded up to an open condition where it is expanded for use, the collapsible cart comprising:
- a rigid frame forming a compartment in the open condition, the rigid frame having a front wall, a rear wall, a right sidewall, a left sidewall, and a bottom wall, the right sidewall and the left sidewall are configured to fold inwardly in the closed condition, the right sidewall comprising a first right panel rotatably coupled to a second right panel;
- a first lock assembly integrated with the first right panel and the second right panel and configured to selectively lock the first right panel with the second right panel in the open condition, the first lock assembly having a first condition for locking the first right panel with the second right panel in the open condition, and a second condition for unlocking the first right panel from the second right panel, and
- wherein the first lock assembly is integrated with the first right panel and the second right panel in both the closed condition and in the open condition.
A collapsible cart configured to transition from a closed condition where it is folded up to an open condition where it is expanded for use, the collapsible cart comprising:
- a frame defining a compartment, wherein:
- the frame comprises at least five walls, including a first wall, a second wall, a third wall, a fourth wall, and a fifth wall;
- at least three of the walls are configured to fold inwardly toward the fifth wall when the cart is in the closed condition;
- the third wall comprises a first panel and a second panel, the second panel rotatably coupled to the first panel;
- a first fastener configured to selectively secure the first panel and the second panel in the open condition, the first fastener operable between a first state for securing the first panel and the second panel along a first plane in the open condition, and a second state for releasing the first panel and the second panel from the first plane;
- and
- wherein the first fastener is integrated with the first right panel and the second right panel in both the closed condition and in the open condition.
