Definitions
- the present invention relates to a coin validator. i
- Coin validators are used in vending machines and the like to test coins and may also determine their values. Such validators often include a coin path comprising a vertical initial portion, a middle portion where input coins roll 0 down a slope and a vertical exit portion. Various forms of sensor are located to sense coins as they roll along the middle portion of the coin path. It has been found that coins travelling along the coin path are prone to wobble and bounce. This is undesirable as it affects the sensor readings. Consequently there is a need for a way of stabilizing a coin "on the fly”. s
- a coin validator 0 comprising an coin path, characterised by a rounded mass gravitationally biased to protrude into the path whereby to deflect a coin on the fly in the coin path to lie flat against a wall facing the mass across the coin path.
- the validator includes support means to support the mass arranged ⁇ such that the gravitationally induced bias force increases non-linearly as the mass is moved out of the coin path.
- support means to support the mass arranged ⁇ such that the gravitationally induced bias force increases non-linearly as the mass is moved out of the coin path.
- the support means comprises a member defining a sloping path up which the mass can be displaced by a passing coin.
- the sloping path may be progressively steeper for increasing displacement of the mass out of the coin path thereby causing the gravitationally induced bias force to increase non- linearly as the mass is moved out of the coin path.
- the support means may comprise a cup extending outwardly from a wall of the coin path.
- the cup may be defined by an open frame.
- Another embodiment of the support means comprises a pair of converging rails.
- the mass is press-fitted through a wall of the coin path to be received by the support means.
- the mass comprises a ball.
- alternative shapes could be used such a cylinder.
- the mass is free to roll.
- the wall opposite the mass is tilted away from a wall through which the mass protrudes.
- coin includes disc-like tokens, as used in vending, gambling and games machines.
- Figure 1 shows the general form of a first coin validator according to the present invention
- Figure 2 is a simplified sectional view through AA of the validator of Figure l;
- Figure 3a is a partial sectional view through BB of the validator of Figure 1;
- Figure 3b a partial top view of the validator of Figure 1;
- Figure 4 is a sectional view through CC in Figure 3b;
- Figure 5a is a side sectional view of an alternative ball retaining structure according to the present invention;
- Figure 5b is a top sectional view of the structure of Figure 5a;
- Figure 6 is a side view of a second validator according to the present invention;
- Figure 7 is a partial sectional view of the coin validator of Figure 6 from the other side; and J Figure 8 shows the coin entry slot and surrounding bezel of the validator of Figure 6.
- a validator 1 has a generally rectangular body.
- a coin 0 entry opening 2 is provided to one end of the top face of the validator 1.
- Coin accept and reject openings are provided in the bottom face of the validator 1.
- a hinged reject gate 3 forms the upper part of one side face of the validator 1. s The lower part of this face forms a reject cover 4. The coin accept/reject mechanism is mounted to the reject cover 4.
- a sloping rundown 5 (see Figure 2) formed on the reject cover 3 extends from an end wall 6 below the coin entry opening 2 about half way to the opposite 0 end wall of the validator 1.
- Various sensors 8 (see Figure 3 a) are mounted on the side wall 9 (see Figure 3 a) of the validator 1 opposite the reject gate 3 where they will be passed by coins on the rundown 5.
- a hole 10 is formed through the reject gate 3 at a position between the coin S entry opening 2 and the rundown 5.
- a skeleton cup 11 is mounted over the hole 10 and retains a steel ball 12. The ball 12 is gravitationally biased so that it protrudes into the coin path through the hole 10.
- the cup 11 comprises an upper horizontal U- shaped member 11a, the legs of which are joined at their ends to the reject gate 3, and a arcuate leg lib extending from the middle of the U-shaped member lib to a point on the reject cover 3 immediately below the hole 10. J
- the ball 12 is retained within the cup 11 but is free to move towards and away from the coin path.
- the arcuate form of the leg lib means that progressively more force is required t ⁇ displace the ball 12 further out of the coin path.
- the rim 13 around the hole 10 is bevelled to allow maximum protrusion of the ball 12 into the coin path commensurate with it being retained within the cup 11.
- the ball 12 is inserted into the cup 11 by pressing it through the hole 10 from the coin path side. This is possible as the rim 13 is able to deform. Once the ball 12 has been inserted the lip 13 s returns to its initial configuration and the ball 12 is retained.
- the operation of the embodiment of Figures 1, 2, 3a, 3b and 4 will now be described for a relatively large coin, for instance a UK fifty pence piece.
- the coin 14 enters the coin path through the coin entry opening 2 in the direction 0 of Arrow A in Figure 3a and falls towards the rundown 5.
- the coin 14 strikes an upper region of the ball 12 causing it to be pushed back out of the coin path in the direction indicated by Arrow B in Figure 3a (this may involve the coin bouncing on the ball a few times).
- the movement of the ball 12 absorbs the kinetic energy of the coin 16.
- the coin 16 passes S the ball 12, it is defle ⁇ ed by the surface of the ball 12 against the wall 9 of the coin path.
- the wall 9 is tilted at approximately 5° to the vertical and, consequently, once the coin 16 is lying against the wall 9, it is retained in contact therewith by gravity.
- a trapezium is formed by a pair of arms 17 extending outwardly from either side of a lower portion of the hole 10, a cross-piece 15 which joins the outer ends of the arms 17 where they are closest together and the reje ⁇ gate 3.
- the ball 12 rests on the inner, upper edges of the arms 17.
- a knob 16 is provided on the cross- piece 15. The knob 16 is dimensioned such that the gap between it and the top of the hole 10 is less than the diameter of the ball 12.
- This embodiment operates in substantially the same manner as that described above although the displacement force for the ball is a substantially linear fun ⁇ ion, due to the linear arrangement of the arms 17.
- the displacement force required can if required be made non-linear by arranging for the arms 17 to curve towards each other. 0
- a validator comprises a validator body 20 which is removably attached to a face plate 21.
- a coin entry slot 22 is provided in an insert 23, received in an aperture in the face plate 21.
- An upper portion of a side wall of the validator body 20 comprises a reje ⁇ gate 24.
- a first coin rundown is defined between the reje ⁇ gate 24 and the opposite wall 25 of the validator body 20.
- the 0 floor of the run down is provided by a ledge 25 on the reje ⁇ gate 24 which slopes down from a point below the coin entry slot 22.
- the reje ⁇ gate 24 and the opposite wall 25 have portions 24a,25a which extend upwardly in a region adjacent the coin entry slot 22 to define a space for receiving entering coins 27.
- An upwardly inclined cylindrical cup 28 is provided on the reje ⁇ gate 24.
- the cup 28 is located across the root of the upwardly extending portion 24a of the reje ⁇ gate 24 and retains a ball-29 which protrudes towards the opposite wall 25 almost fully across the width of the rundown.
- the cup 28 is positioned such that part of a quadrant of the ball 29 is just visible through o the coin slot 22 (see Figure 8).
- the stabilizer according to the present embodiment j ensures that both large and small coins proceed along the run down, lying flat against a wall thereof.
- the present invention has been described with reference to validators having a sloping rundowns. However, the present invention can be usefully applied to 0 other forms of validators.
- a plurality of the stabilizing structures of the present invention can be employed in a single validator if a plurality of spaced sensors are present and, particularly, if the wall of the coin path does not slope to retain coins in the corre ⁇ position.
- a plurality of the stabilizing stru ⁇ ures may also be found advantageous where a coin to be tested passes s sensors in a vertical coin path.
- the cup of the first embodiment can have a solid wall, the skeleton structure being 0 convenient if the reje ⁇ gate and cup are to be moulded as a single unit.
- the cup or other support means may be formed separately and attached to the reje ⁇ gate by many different techniques including gluing, welding and using fasteners S such a screws.
- the ability to press-fit the ball is not essential and the ball or other mass may be placed in its support by other means.
- the hole could be sufficient to allow the ball to pass and a retainer attached at the coin path side 0 of the hole after insertion of the ball.
- the support means is formed separately from the reje ⁇ gate, the mass may be placed in the support before it is attached to the validator.
- the ball may be made from any convenient dense material, e.g. stainless steel, glass or ceramic material.
- the ball may be solid or hollow to obtain the necessary weight ratio. A large ball can reach across a larger coin path but may be too heavy unless it is hollow.
- the ball is rotatable, and the conta ⁇ of coins entering the validator may produce rotation of the ball.
- the ball may not be spherical, but can be of some other shape e.g. elliptical.
- Masses other than balls may be used, for example a generally cylindrical roller, in which case it may be advantageous to taper or dome its ends to minimize the risk of it becoming stuck in a position so as to occlude the coin path.
- the mass is biased solely gravitationally without the aid of a spring, although a spring may additionally be used.
- the spring may provide a light bias to augment the gravitational bias.
