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
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. 2. The device of claim 1 wherein the supporting material comprises flexible and load bearing material that, when the device is in the first orientation, comfortably supports the weight of a person, and when the device is in the second orientation, stably supports the weight of the one or more objects when being pushed. 3. The device of claim 1 wherein the wheel is located posteriorly of a region of the supporting material adapted to support the torso of a person when the device is positioned in the first orientation. 4. The device of claim 1 wherein the handles comprise leg frame members which are adapted to engage the ground when the device is positioned in the first orientation. 5. The device of claim 1, wherein the latch arrangement comprises a latch lever pivotally mounted on the handle frame bracket, and a catch secured on the body frame bracket. 6. The device of claim 1, wherein the pivoting joint is connected to each of the brackets and allows the brackets to pivot relative to each other when the latch arrangement is in an unlocked condition, whereby planar surfaces of the brackets align and abut each other at the junction of the handle frame member, main body frame member and leg frame member.
