Patent Application
20160371915
The current application relates to coin chutes, and in particular to coin chutes that impede the fishing of coins.
Devices and machines that accept coins for payment, such as parking meters and vending machines, are typically unattended and located in public areas. As such, they are sometimes the subject of vandalism, and theft of, for example, either the parking meter itself or the coins used to pay for parking. With respect to parking meters, they generally include a coin chute into which coins are inserted. As the coin passes through the coin chute it may pass an arrangement of one or more sensors, typically inductive coils that can discriminate the value of the coin. When a coin passes through such a coin discriminator comprising discrimination sensors in the meter it travels from the upper portion of the parking meter housing and enters into a coin canister located in a lower vault, which is secured against theft by way of a hardened and locked housing.
Some coin chutes have an anti-pull back device (or assembly) that prevents or impedes coins from being pulled back and out of the coin chute. For example, pulling a coin back and out of the coin chute may be done by using a string fastened to the coin, and then pulling the coin out of the chute after the coin has fallen down the coin chute and been detected by the discrimination sensors. By employing an anti-pull back device, the same coin is prevented from being pulled back up the chute. This in turn prevents the same coin from passing through the discrimination sensors multiple times in order to receive credit for paid parking time without having deposited the required amount of coins. These anti-pull back devices can be found both in the meter, as well as at the entrance to the coin canister located in the lower vault area. The anti-pull back devices may be mechanical and may include a plurality of hinged fingers crossing the coin path. When the coin travels down the coin chute, the fingers may rotate out of the way. However, when the coin is attempted to be retrieved and pulled back up the coin chute, the fingers may be prevented from rotating out of the way.
While anti-pull back devices can prevent or impede pulling back the same coin in order to be counted numerous times, they may not prevent or impede all types of schemes to defraud a parking authority, or the public, of money. For example, a vandal or thief may force a foreign object into the coin chute in order to cause a jam in the coin chute, such as a jam just above the anti-pull back device that is located further down the coin chute. The foreign object may be non-metallic so that it may not be detected by sensors in the coin chute, which results in the parking meter remaining in service. When an unsuspecting customer attempts to make a payment, the inserted coins will remain in the coin chute instead of passing into the coin vault area. The thief or vandal may then attempt to fish out the inserted coins that are still in the coin chute.
An improved, additional or alternative coin chute that can impede the fishing of inserted coins from the coin chute is desirable.
In accordance with the present disclosure, there is provided a coin chute for use in a vending machine comprising: a coin channel defined by a first sidewall and a second sidewall opposite the first sidewall, the channel having a first portion through which coins may be inserted into the coin chute, and a second portion through which coins exit the channel; a coin discriminator for determining a denomination of coin passing the discriminator; and a first anti-fishing assembly located between the first portion of the channel and the coin discriminator comprising an anti-fishing finger rotatable between a first position in which the anti-fishing finger extends across the channel and a second position in which the anti-fishing finger is rotated out of the channel.

In an embodiment of the vending machine, the goods or services metered comprises parking time for a parking space.
Further features and advantages of the present disclosure will become apparent from the following detailed description, taken in combination with the appended drawings, in which:
A parking meter that incorporates a coin chute including an anti-fishing assembly or anti-fishing device may impede withdrawal of coins from a coin chute. As described further herein, the anti-fishing assembly (or device, as referred to interchangeably herein) may be incorporated into a coin chute during manufacture. The anti-fishing assembly may be incorporated into the coin chute in addition to an anti-pull back assembly that prevents or impedes a coin from being pulled back past a coin discriminator a plurality of times. As described further below, the anti-fishing assembly provides an obstacle in a coin channel that impedes fishing coins from the coin channel as well as reduces the number of coins that can be held within the coin channel. As described further below, the anti-fishing assembly comprises at least one anti-fishing finger that is located within an upper section of the coin channel.
The anti-fishing assemblies and anti-pull back assemblies are similar in purpose, namely to prevent or impede the withdrawal of inserted coins; however, each of the assemblies are directed to defeating different types of attacks. The anti-pull back assemblies prevent or impede inserted coins from being pulled back past the coin discrimination circuitry to have a single inserted coin counted multiple times. The anti-fishing assemblies of the present invention prevent inserted coins from being withdrawn from the coin channel, even if they have not passed the coin discrimination circuitry. Additionally, the anti-fishing assemblies of the present invention reduce or at least somewhat minimize the volume in the coin channel within which coins can rest in the event of a blockage within the coin channel, and as such reduce the number of coins that could potentially be fished out. As an example, a coin chute having only anti-fishing assemblies may be susceptible to time theft by inserting a coin on a string and repeatedly pulling the coin back past the discrimination circuitry. Although the anti-fishing assemblies may prevent the inserted coin from being retrieved, the coin may be counted multiple times and as such a single coin such as a nickel or dime may be used to pay for a dollar, two dollars or more of parking time. While the anti-pull back assemblies may prevent such types of attack, if there is a blockage in the chute, coins may accumulate in the coin channel by resting on top of the blockage. These accumulated coins may then be fished out of the coin channel; the anti-pull back assemblies do not provide any deterrent to such an attack.
In addition, the removable parking meter mechanism 102 may comprise alternative payment means such as a card payment means 114. The parking meter mechanism 102 may include a solar panel 116 for charging a battery pack of the mechanism. The parking meter mechanism 102 may also include one or more input controls 118 for controlling operation of the meter mechanism, as well as a display 120 for displaying an amount of parking time purchased.
Although not depicted, multi-space parking meters often have a number of the same components as the single space parking meter 100 of
A thief wishing to defraud a parking authority may do so in a number of different types of attacks. For example, a thief may place a coin attached to a string into the coin chute. Once the coin passes the coin discriminator, the thief can pull the coin up past or above the coin discriminator, and then allow the coin to be lowered and pass through the discriminator again. In order to prevent this type of theft, the coin chute 202 may include an anti-pull back assembly that prevents a coin 204 from being pulled up the coin chute once it has passed the coin discriminator. In addition, if the coin travels into the coin canister in the vault area, the coin canister may also have built-in anti-pull back levers that will trap the coin inside the coin canister. The anti-pull back assembly may comprise a number of moveable fingers that are pivoted out of the path of a downward-moving coin by the downward force of the coin, but are prevented from pivoting out of the coin path when the coin is pulled upwards. Although the anti-pull back device can prevent a single coin from being counted a plurality of times, other types of fraud are possible. For example, a thief or vandal may insert an object into the coin channel to block the channel. In this situation, when a user inserts a coin, it will enter the coin channel; however, it will not pass the anti-pull back assembly due to the foreign object jam. The inserted coin or coins will remain in the coin channel, and once the user leaves the parking meter, the thief may approach the meter and fish the inserted coins out of the coin channel. The addition of optical sensors incorporated into the coin chute, along with corresponding software, could provide additional detection of jams within the coin channel and place the parking meter into a non-functioning state; however, retrofitting or adding the required optical sensors to the coin chute may not be possible or practical, and may require replacement of the entire coin chute assembly. Moreover, additional sensors and/or software may result in increased power consumption, which is generally undesirable for unattended vending machines, including parking meters, which typically rely upon batteries for power supply.
In order to discourage fishing types of theft, an anti-fishing assembly may be incorporated into the coin chute. The anti-fishing assembly is preferably placed as close as possible to the insertion point of the coin chute but without being visible, or being of reduced or limited visibility, to a person at least horizontally peering into the coin chute at coin slot 112. Placing the anti-fishing assembly as close as possible to the insertion point of the coin chute in this regard reduces or at least somewhat minimizes the volume in the coin channel within which coins can rest in the event of a blockage within the coin channel, and as such reduce the number of coins that could potentially be fished out. As described further herein, the anti-fishing assembly may comprise one or more fingers that extend from a side of the coin channel into the coin channel. The fingers allow a coin to be inserted into the coin channel; however, if the coin is attempted to be withdrawn from the coin channel, the fingers may block the coin from being withdrawn.
A coin chute with an anti-fishing assembly used in the parking meter of
When a coin is inserted into the coin chute, it passes through the opening 304 and into a coin channel. The coin channel 318 may be formed from two connected walls 318a, 318b (see
The coin chute 202 includes an anti-fishing device, or anti-fishing devices, 314, 316. Like the anti-pull back devices 328, the anti-fishing devices 314, 316 prevent, or at least hinder, the withdrawal of coins from the coin chute. In particular, the anti-fishing devices 314, 316 prevent or hinder the withdrawal of coins that may be resting in the coin chute above the anti-pull back device 328. The anti-fishing devices 314, 316 are located within the coin channel 318 so that they impede withdrawal of coins. As depicted in
The anti-fishing devices 314, 316 may include a plurality of spaced apart rotatable fingers. The fingers may be constructed or assembled in a manner similar to or the same as the manner in which fingers for known anti-pull back devices are constructed or assembled. For example, the fingers of anti-fishing devices 314, 316 may rotate into the coin channel under the force of gravity, or some other slight biasing means. In order to allow the fingers to rotate freely within the coin channel, the outer housing 302a of the coin chute may include a cut out portion 330 to allow the fingers to rotate. When a coin is inserted into the coin channel, the coin passes down the coin channel and the force of the coin rotates the fingers out of the coin channel. Once the coin passes the anti-fishing devices, the fingers rotate back into the coin channel to prevent any coins that may be at rest in the coin channel from being pulled up or withdrawn past the anti-fishing devices and out of the coin channel. The anti-fishing devices 314, 316 reduce the volume of space within the coin channel in which coins may be at rest. For example, the anti-fishing devices 314, 316 reduce the available volume of space within the coin channel that may be available for accumulating and withdrawing coins due to a jam, or obstruction in the coin channel. This is because coins accumulated below or downstream of the anti-fishing devices due to jams or obstructions located below or downstream of the anti-fishing devices 314, 316 are not available for withdrawal as a result of the operation of the anti-fishing devices 314, 316. Preferably, and as shown in
As depicted in
As discussed above and depicted in the Figures, the anti-fishing device 316, which is located on the side of the coin channel that is towards the coin entrance (as opposed to away from the coin entrance as is the case with anti-fishing device 314), may have a wider spacing between its fingers in order to impede fishing of larger sized coins. The anti-fishing device 314 may have narrower spacing between its fingers and may be located further up the coin channel relative to anti-fishing device 316. The narrower spacing of the fingers may be useful in preventing the withdrawal of smaller sized coins.
The anti-fishing finger 800, as well as the anti-fishing fingers described above, may include a counter weight portion 808 on the opposite side of the pivot point 806. The counter weight portion 808 may provide sufficient weight to rotate downward and cause the end of the finger 804 to rotate into the coin channel. The counter weight portion 808 is light enough so that the anti-fishing finger may be rotated out of the coin channel under the weight of a falling coin.
Preferably, the fingers of the present description are coloured black or a dark colour so that a person peering into a coin channel would have greater difficulty identifying or locating any fingers than if the fingers were of a bright or light colour. Minimizing the visibility of the fingers to potential vandals and thieves is preferred.
In order to further minimize the amount of theft of coins by vandals or thieves that may engage in fishing activities with respect to coin chutes, an insert or filler piece/object (not shown in the Figures) may be inserted into the coin channel such that the insert or filler object occupies a space extending from the entrance to the coin channel to the anti-fishing devices, either in whole or in part. The purpose of the insert or filler object is to restrict or narrow the width of the coin channel. By narrowing the width of the coin channel to, for example, accommodate the width of only one high value coin, the ability to fish coins is impeded, as the insert or filler prevents multiple coins from accumulating side-by-side in the coin channel.
A coin chute incorporating an anti-fishing device, as well as a parking meter incorporating a coin chute with an anti-fishing device, have been described by way of examples. It will be appreciated that components of one example may be incorporated into another example. Furthermore, although specific embodiments of a coin chute are described, it will be appreciated that anti-fishing fingers may incorporated into coin chutes of different designs. Variations and modifications not described herein will be apparent to one of ordinary skill in the art having regard to the description herein.
