An axle-free wheel comprising: an outer rim member having a ground interface on an external surface thereof and an outer ball race or rolling race on an inner surface thereof; an inner rim member having an inner ball or rolling race on an outer surface thereof.

Collapsible carts are disclosed. The collapsible carts include a frame, a load bearing member and a wheel assembly. The wheel assembly includes a housing with a horizontal pin channel and an elongated diagonal channel. The horizontal pin channel may be adapted to guide a pin to transpose horizontally along the horizontal pin channel while rotatably coupling a leg member of the frame to a horizontal section of the load bearing member. The elongated diagonal channel may be adapted to guide the horizontal section of the load bearing member to pivot around a pin axis and move from a horizontal plane in the open condition to a generally vertical plane in the closed condition. The movement of the horizontal section along the elongated diagonal channel actuates the housing to rotate around the generally vertical axis.

A tote-dolly system is configured to enable quick detachable attachment of the tote to the dolly. An exemplary tote has one or more tote-fasteners that can be quickly engaged with corresponding dolly-fasteners. An exemplary fastener may be a buckle having a clip and receiver that is quickly engaged. A preferred fastener is a hook-and-loop fastener configured on the top of the dolly and on the bottom of the tote. It may be preferred to have one of the tote-dolly components have discrete pieces of hook-and-loop fastener to facilitate detachment of the components.

A universal motorcycle storage case mounting assembly that detachably secures to a motorcycle or other vehicle, allowing a user to safely transport personal belongings to a destination. The mounting assembly utilizes two main componentsa base frame and a platform, with a storage case being couplable to the platform, forming a transportable storage case. In order to secure to a motorcycle or other vehicle, the mounting assembly utilizes a triple-locking system, including a base latch bracket that attaches to the motorcycle; a receipt on the platform; and a platform latch bracket, the receipt and the platform latch bracket configured to secure the platform to the base frame. As a result of the locking system, the storage case requires force to detach from the motorcycle, thereby preventing inadvertent detachment. Upon arrival at a destination, a rider can detach the transportable storage case, rather than leave belongings on the motorcycle.

A multifunctional luggage implement configurable to form a child seat, desk and/or changing station, having a retractable stroller portion in some embodiments.

An axle-free wheel comprising: an outer rim member having a ground interface on an external surface thereof and an outer ball race or rolling race on an inner surface thereof; an inner rim member having an inner ball or rolling race on an outer surface thereof.

One embodiment of a portable shade maker comprises a collapsible cart and a telescoping and tiltable umbrella for the protection and comfort of individuals conducting activities that is lightweight and easy to relocate according to the chosen activity.The load platform can have a flange base that can accept and secure an umbrella. In addition, it can be used to carry supplies, tools, and activity equipment on its load platform to the destination location.

A backpack structure is adapted to provide a storage space, and integrated with a tent structure. The backpack body has a right connection portion and a left connection portion to connect the left sidewall and the right sidewall, wherein the connections are pins, buttons, strips or velcros. The tent structure is stored in the compartment of the backpack body, or the left sidewall and the right sidewall. The tent structure includes a tent base, a left tent portion and a right tent portion. The compartment may has pads, made of cushioning materials, such as foam, to replace the camping mat, for rest. Therefore, the backpack structure of the invention is light for the users of outdoor activities. Moreover, the backpack structure may combine with a trolley structure for drawing easily, or the backpack structure may be designed as a luggage suitcase.

The present utility model refers to a rolling device and, more particularly, an improved multi-directional ball caster-type device having an increased slope, which means a smaller angular slope level, or a more acute inclination angle between the central vertical axis of the device and the surface upon which it rolls. The slope, or inclination angle of the present improved device is from 62 to 50, or less. As the inclinations angle can be more acute, the object supported on the rolling system, e.g. a luggage case, can be more sloped without having friction between the main ball involving structure and the ground.

A set of transportable containers, including at least two transportable containers, each one of the type of a suitcase, a trunk, a chest, a trolley case and the like.

The set includes elements for the mutual retention of the containers, which can be actuated in at least one stacking configuration wherein a bottom of a first container is rested in parallel on a lid of a second container in a specific mutual and active arrangement. The elements for mutual retention are selectively deactivatable in order to allow the mutual spacing apart of the containers.
