Abstract
An interlocking case system includes a base case having a luggage receptacle and an overlying lid that together form a luggage compartment. One or more swivel wheels are located in proximity to one end of the base case and at least one non-swivel wheel is located at the other end. An upper case is configured to interlock with, and be supported by, the base case when the base case is supported by the first and second swivel wheels and the at least one non-swivel wheel. The case system may be towed using a flexible towing strap coupled to the base case.
Claims26
An interlocking case system comprising:
- a base case comprising:
- a luggage receptacle and an overlying lid that together form a luggage compartment, the luggage receptacle having first and second ends and an underside that is opposite to the lid;
- first and second non-swivel wheels located at opposite side regions on the underside of the luggage receptacle in proximity the first end of the luggage receptacle;
- at least one swivel wheel located on the underside of the luggage receptacle in proximity the second end of the luggage receptacle;
- and
- a flexible towing strap coupled to the base case, and
- a first upper case configured to interlock with, and be supported by, the base case when the base case is supported by the at least one swivel wheel and the first and second non-swivel wheels.
An interlocking case system comprising:
- a base case comprising:
- a luggage receptacle and a first overlying lid that together form a luggage compartment, the luggage receptacle having first and second ends and an underside that is opposite to the lid;
- first and second non-swivel wheels located at opposite side regions on the underside of the luggage receptacle in proximity the first end of the luggage receptacle;
- a first swivel wheel located on the underside of the luggage receptacle in proximity the second end of the luggage receptacle;
- and
- a flexible towing strap coupled to the base case, and wherein the base case is configured the support and interlock with a first upper case when the base case is supported by the first swivel wheel and the first and second non-swivel wheels.
A method for transporting cases comprising:
- placing a first upper case on top of a base case that is supported at a first end by a pair of swivel wheels and at a second end by first pair of non-swivel wheels;
- engaging an interlocking mechanism that prevents lateral motion of the first upper case relative to the base case;
- and
- maneuvering the base case using a flexible towing strap connected to the first end of the base case,
- wherein the interlocking mechanism comprises a first pair of rails located on the underside of the first upper case and a second pair of rails located on the top side of the base case, the first and second pairs of rails having different lateral spacing.
