Abstract
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.
Description
- The present invention relates to coin-chutes particularly although not exclusively, for use in telephone coin-box instruments known also as payphones.
- A major problem in such payphones is the efficient utilisation of the available space by the apparatus which is housed within the device.
- Accordingly it is an object of this invention to provide a coin chute which is adapted to make the most efficient use of space within the payphone while maintaining an efficient operation in the presence of coins.
- According to the present invention, there is provided a coin chute comprising first and second runways each adapted for the passage of coins by means of gravity in which the first runway is adapted to be connected at one of its ends to the second runway at one of its ends in such manner, whereby when a coin is placed in the first runway, it rolls freely along this runway in a first direction and upon reaching the point of connection of the two runways is adapted to enter the second runway whereupon it rolls freely along this runway in a second direction.
- The invention will be more readily understood from the following description of two exemplary embodiments which should be read in conjunction with the accompanying drawings in which:-
- Fig. 1. Shows a view of part of a payphone, portions of which are cut away to illustrate the positioning of a typical coin chute within the payphone;
- Fig. 2. shows the relevant portions of a coin-chute in accordance with the present invention with certain sections of the walls of the chute cut-away to enable the internal features to be observed;
- Fig. 3. shows a section of the chute as shown in Fig. 2 as viewed in the direction of the arrows of section A - A; and,
- Fig. 4. shows a further view of the coin-chute in accordance with this invention but with a modification to incorporate a coin store (the walls of the chute are cut-away to enable observation of the internal features).
- Referring to Fig. 1. which shows a typical coin-
chute 1 located within a payphone. Thechute 1 has associated with it coin detection mechanisms such as coin reject 2, validator 3, flushing 4 and cash box/refund 5. - A
coin store 6 and a refund draw ? are shown at the lower part of the instrument. - Referring now to Fig. 2. to Fig. 4. of the drawings, it will be seen that the chute comprises a first
upper runway 8 and a second lower runway 9. Both runways are inclined to the horizontal by an angle α to enablecoins - A
coin 10 in the upper runway moves in a first direction of motion A, whereas acoin 11 in the lower runway moves in a second direction of motion B. In effect the coin travelling down the coin chute has a reversal in direction of motion. - The change in direction of motion has to be carefully controlled and is achieved at the junction of the upper and lower runway by means of a specially designed
impact face 12 and a connectingsurface 13 between both coin runways. - As explained, under the action of gravity a coin entering the
upper runway 8, rolls down the runway and strikes theimpact face 12. Thisimpact face 12 has a low coefficient of restitution to restrict the coin rebound and accordingly as the coin's controlled rebound takes effect, the coin slides down an inclined connectingsurface 13 into thelower runway 8. The coin now rolls down this runway also under the action of gravity. - The material used at the
impact face 12 must exhibit a high mechanical hysteresis and an example of such a material is Neoprene rubber. This can be bonded to a backing material which can be an integral part of the runway moulding. Alternatively a soft P.V.C. can be used, coated on Aluminium, or even a loose fitting insert of plastics or metal exhibiting pendulum damping, may be used. -
- where e - coefficient of restitution
- µ = coefficient of friction
- V = velocity of impact
- g = acceleration due to gravity
- α = runway angle
- This formula is derived as follows:-
- At the instant of rebound of the coin, it should be assumed that the velocity is equal to VI and that it reduces to zero through a rebound distance x.
- Now, the retarding force of the coin = mass x acceleration. If also it is assumed that w is the weight of the coin perpendicularly downwards on the runway, which is inclined at an angle α to the horizontal, and µ is the coefficient of friction, then
- If velocity = V and the coefficient of restitution of the impact face = e
- then V = e V and
- As previously stated.
- The angle p that the chute takes up from the vertical, is necessary to ensure that coins passing down the runways remain in abutment with one of the runway walls only. This is to enable correct detection of the passage of coins by coin detection mechanisms adjacent these walls.
- In the modified coin-shute shown in Fig. 4. there is provided a step-down
area 15 of sufficient size to accommodate a certain number of coins to enable a degree of coin-storage. It will be seen that the floor of thelower runway 16 from theimpact face 12 is a steeper angle than the lower runway itself. This is to prevent coin blockage.
