摘要:
Apparatus comprising at least three 3 dimensional shapes (2, 4, 6, 8,10) a first one (2) of said three dimensional shapes being rotatably supported within a second one (4) of said three dimensional shapes/ said second one of the three dimensional shapes being rotatably supported within a third one (6) of said three dimensional shapes, at least one of said three dimensional shapes comprising an opening (22-30) capable of connecting at least one. of said shapes to another.

Carriers for loads are disclosed, especially beach use, e.g. as beach carriers or for transporting kayaks or canoes. A foldable assembly of two elongate members (1, 2) forms a frame, the two members being pivotally connected at one end (3), and their other ends carrying wheels (10, 11). A support strap (6) or foldable support between the elongate members, and the members themselves, forms a stable base for the load, and the wheels (10, 11) enable it to be pushed or pulled along. Preferably the wheels (10, 11) are hemispherical with their axes of rotation inclined downwardly and outwardly with respect to the elongate load.

Carts, trolleys or like load-carrying apparatus, for example a wheelbarrow, are disclosed. They incorporate two wheels (2, 3) which rotate about separate axes of rotation (4, 5) which are coplanar but inclined to one another, preferably at an angle (α) between 50 ° and 100 °. They are mounted on a base structure or frame (1) in such a way that when the apparatus rests on horizontal ground, the plane containing the axes of rotation of the wheels (4, 5) may be moved to be vertical to allow the wheels to turn easily as the apparatus is moved along the ground, and moved away from vertical to cause the entire apparatus to be braked (as the wheels then try to travel in different directions across the ground). This principle may be applied to three and four-wheeled load-carrying apparatus.
