Abstract
A trolley system for transferring cargo in relation to a cargo compartment of a vehicle includes a frame defining a cargo-retaining platform. The cargo-retaining platform is configured to receive and retain the cargo. At least a portion of a lower surface of the frame is formed of a low friction material. One or more handles are moveably coupled to the frame. The handle(s) are configured to be moved between a retracted position and an extended position. One or more attachments are configured to secure the cargo on the cargo-retaining platform.
Claims20
A method for transferring cargo in relation to a cargo compartment of a vehicle, the method comprising:
- positioning a retaining pan of a frame of a trolley system underneath the cargo;
- retaining the cargo on a cargo-retaining platform of the frame;
- securing the cargo on the cargo-retaining platform with one or more attachments coupled to the frame;
- moving one or more handles coupled to the frame between a retracted position and an extended position;
- and
- sliding a portion of a lower surface of the frame formed of a low friction material over a floor surface.
A method for transferring cargo in relation to a cargo compartment of a vehicle, the method comprising:
- positioning a retaining pan of a frame underneath the cargo;
- retaining cargo on a cargo-retaining platform of the frame of a trolley system;
- securing the cargo on the cargo-retaining platform with one or more attachments coupled to the frame;
- moving one or more handles coupled to the frame between a retracted position and an extended position;
- sliding a portion of a lower surface of the frame formed of a low friction material over a floor surface;
- upwardly pivoting the trolley system, by the one or more handles in the extended position, so that one or more rollers directly contact a floor;
- and
- rolling the trolley system via one or more rollers coupled to the frame.
A method for transferring cargo in relation to a cargo compartment of a vehicle, the method comprising:
- positioning a retaining pan of a frame underneath the cargo, wherein the frame comprises:
- (i) low friction pads that are formed of a low friction material, (ii) a chamfered first lower edge at a first end, and (iii) a chamfered second lower edge at a second end that is opposite from the first end;
- retaining cargo on a cargo-retaining platform of the frame of a trolley system;
- securing the cargo on the cargo-retaining platform with one or more attachments coupled to the frame, wherein the one or more attachments comprises one or more straps;
- moving one or more handles coupled to the frame between a retracted position and an extended position, wherein said moving comprises outwardly extending a first grasping portion and a second grasping portion of the one or more handles from the frame when the handles are in the retracted position;
- sliding a portion of a lower surface of the frame formed of the low friction material over a floor surface;
- upwardly pivoting the trolley system, by the one or more handles in the extended position, so that one or more rollers directly contact a floor, wherein lower surfaces of the one or more rollers are within a plane that is above or coplanar with the lower surface of the frame, and wherein the trolley system is upwardly pivoted via the one or more handles in the extended position about an axis of the one or more rollers so that the one or more rollers directly contact the floor and allow the trolley system to be rolled via the one or more rollers;
- and
- rolling the trolley system via one or more rollers coupled to the frame.
A method for transferring cargo in relation to a cargo compartment of a vehicle, the method comprising:
- retaining cargo on a cargo-retaining platform of a frame of a trolley system, wherein the frame comprises low friction pads that are formed of a low friction material;
- securing the cargo on the cargo-retaining platform with one or more attachments coupled to the frame;
- moving one or more handles coupled to the frame between a retracted position and an extended position;
- and
- sliding a portion of a lower surface of the frame formed of the low friction material over a floor surface.
