Abstract
An improved structure of case body includes receiving containers for receiving wheel sets to stow therein. When the case is moved, especially when the case is pushed or pulled, the wheel sets stowed in the receiving containers can be selectively extended outside the case to allow 360 degree rotation with the aid of wheels of the wheel sets and when a user wishes to place the case for the purposes of for example shipping or transportation of baggage, the wheel sets mounted to the bottom of the case can be first retracted back into and stowed in the receiving containers of the case to avoid undesired impact of the wheel sets during the transportation of the case to thereby extend the service life thereof and also to reduce the amount of space needed between adjacent case.
Claims9
A structure of case, comprising:
- a case body, which has a top and a bottom and forms therein a receiving space adapted to receive and hold at least one article;
- a plurality of receiving containers, each of which is arranged inside the bottom of the case body and has a top and a bottom, the bottom forming an opening;
- a plurality of wheel sets, which is respectively receivable in the receiving containers and each comprises an elastic element, a base, and a wheel, the elastic element having a first end fixed to the top of the respective receiving container and a second end fixed a top of the base, the wheel being fixed to a bottom of the base;
- and
- a plurality of fastener assemblies, each of which comprises a handle, a support section, and a stop section, the handle being pivotally mounted to an outside wall of the case body at a location adjacent to the bottom of the case body and corresponding to a corresponding one of the receiving containers, the support section projecting from the handle to extend through the outside wall of the case body and be partially received in the corresponding receiving container, the support section being positionable against the bottom of the base to support the base, the stop section being arranged at the bottom of the case body, wherein the fastener assemblies are of a number corresponding to the number of the wheel sets and that of the receiving container.
