<p>To make the most efficient use of space, in for example, a telephone coin-box instrument, the coin runway requires to be folded back-upon itself. This requires that the direction of motion of the coin in the runway is reversed without creating a potential coin jamming situation. The coin runway consists of two sections (8,9) interconnected by the direction changing area. Under the action of gravity a coin (10) rolls down the upper coin runway (8) and strikes an impact face (12) in the direction changing area. The impact face (12) incorporates a material which has a low coefficient of restitution to restrict the coin rebound. The direction changing area also includes a downward inclined connecting surface (13), and as the coin rebounds, it slides down the connecting surface into the lower coin runway (9). In a modified version of the arrangement the step down area (15) is of sufficient size to be included as part of a coin store, and the floor of the arrangement is angled (16) to prevent coin blocking.</p> |
