A convertible dual purpose device (10) has a frame (12) movable between an expanded configuration and a collapsed configuration, supporting material (28) connected to the frame for supporting one or more objects, handles (14, 16, 18, 20) at a first end of the frame, and a wheel (26) at a second end of the frame. When the frame is in the expanded configuration, the device can be positioned in a first orientation whereby the supporting material is adapted to serve as a load support for a chair, or in a second orientation whereby the supporting material is adapted to serve as a load support for a wheel barrow. When the frame is in the collapsed configuration, the device can be stored in a carry bag (42). |

1. A convertible dual purpose device comprising:
(a) a frame movable between an expanded configuration and a collapsed configuration, (b) supporting material connected to the frame for supporting one or more objects, (c) a pair of spaced apart handles at a first end of the frame, and (d) a wheel at a second end of the frame, wherein, when the frame is in the expanded configuration, the device is adapted to convert between a chair and a wheel barrow, such that the device can be positioned in a first orientation whereby the supporting material is adapted to serve as a load support of the chair, or in a second orientation whereby the supporting material is adapted to serve as a load support of the wheel barrow, and wherein, when the frame is in the collapsed configuration, the device can be stored in a carry bag,
wherein the handles are located at the end of respective handle frame members which converge in the direction of the second end of the frame,wherein the handle frame members are pivotable with respect to a main portion of the frame when the frame is being moved between an expanded configuration and a collapsed configuration,each handle frame member is adapted to pivot downwardly about a respective pivoting joint when a co-operating latch arrangement is in an unlocked condition so as to allow the device to be collapsed to a collapsed configuration, andwherein the latch arrangement co-operates with a singular pivoting joint which provides a junction between the handle frame member, a main body frame member and a leg frame member, the singular pivoting joint provided at the junction being connected to each of a handle frame bracket, a body frame bracket and a leg frame bracket, whereby the said brackets can pivot relative to each other when the latch arrangement is in the unlocked condition. |
