## Title
Coin validation unit with clip feature

## Abstract

A separate removable and replaceable coin validation unit for use in a coin-operated device has a housing and clip formations by means of which the housing is releasably held in a cavity in the coin-operated device. The coin validation unit is electrically operable and has electrical connectors which connect with complementary connectors in the cavity. The coin operated device is particularly a single bay parking meter.

## Background
This application claims the benefit of U.S. Provisional Application No. 60/909,241, filed Mar. 30, 2007, by King et al., entitled COIN VALIDATION UNIT, which is incorporated in its entirety herein by reference.


FIELD OF THE INVENTION
THIS INVENTION relates to a coin validation unit and a device having the coin validation unit.
SUMMARY OF THE INVENTION
According to a first aspect of the invention, there is provided a coin validation unit that is suitable for use in a coin-operated device, the unit including

    
    
        a housing; and
        clip formations for releasably clipping the housing in the coin-operated device.
    
    


It will be appreciated that the unit is then easily removed from, and inserted into, the device.
In an embodiment of the invention, the coin validation unit is electrically operable. In this embodiment, the coin validation unit has connectors that are electrically connectable to complementary connectors in the coin operated device.
The invention extends to a coin operated device which includes a coin validation unit in accordance with the invention. The body may have a cavity in which the coin validation unit is received. In the embodiment in which the coin validation unit is electrically operable, the body may have connectors complementary to those of the coin validation unit.
The invention extends still further to a coin-operated device which includes:

    
    
        a body having a cavity in which a removable coin validation unit is receivable;
        a removable coin validation unit in the cavity; and
        interoperable clip formations on the body and the coin validation unit.
    
    


Once again, with the electrically operable embodiment, the body and the coin validation unit may have connectable complementary connectors.
Preferably, the device is a parking meter, more specifically a single bay parking meter.



BRIEF DESCRIPTION OF THE DRAWINGS
Embodiments of the invention are now described, by way of example only and without limiting the scope of the invention, with reference to the accompanying figures, wherein:
FIG. 1 is a perspective view of the coin validation unit;
FIG. 2 is a perspective view of the coin validation unit, aligned for insertion into a parking meter; and
FIG. 3 is a perspective view of the coin validation unit when inserted fully into the parking meter.



DETAILED DESCRIPTION
In the accompanying figures, the coin validation unit is generally designated by reference numeral 10 and comprises a housing 12 and a pair of clip formations 14, which are arranged on opposite sides of the housing 12, and which clip formations 14 are used to clip the housing 12 releasably in a coin-operated device, in the fashion described below. The unit 10 has an internal validation pathway (not shown), with an entrance opening 30 and an outlet opening 32. A top opening 34 is located opposite the outlet opening 32. Side portions 36 and 38 indicated at 28 are shown in the drawing.
The particular coin-operated device 16 depicted in FIGS. 2 and 3 is a parking meter. More specifically, the coin-operated device 16 is a single bay parking meter (ie a standalone parking meter). The parking meter 16 is constructed to include a cavity 18 for receiving the coin validation unit 10 therein, and the unit 10 is clipped snugly and releasably in the cavity 18 by virtue of the clip formations 14, as is described in greater detail below. The external shape and configuration of the housing 12 is designed to complement the internal dimensions of the cavity 18. For example, and as is depicted in FIG. 2, the unit 10 includes a pair of flanges 20, which flanges 20 are dimensioned and configured to be received within, and guided along, the corresponding grooves 22 that are provided in the cavity 18 of the parking meter 16.
Each of the clip formations 14 takes the form of a movable angled tooth, which is urged outwardly to project from the housing 12. In a preferred embodiment of the invention, the urging is achieved by means of an internal spring (not depicted). The parking meter 16 includes a pair of recesses 24 in the cavity 18 (Only one recess 24 is visible in FIG. 2. The other recess 24, which is obscured from view in this figure, is located directly opposite the recess 24 in view, in a symmetrical arrangement). Each recess 24 is dimensioned and configured to receive its associated tooth 14 therein when the unit 10 is inserted into the cavity 18. The teeth 24 are mechanically connected to, and movable by, buttons 25. In order to insert the unit 10 into the cavity 18, the user pushes the buttons 25 inwardly and against the urging force, so as to draw the teeth 14 at least partially within the housing 12. The unit 10 is then inserted into the parking meter 16, in the direction of arrow “A” and, when the teeth 14 are aligned with the recesses 24, the buttons 25 are released, causing the teeth 14 to revert to their urged positions in which they project outwardly from the housing 12, and each tooth 14 is held captive within its respective, associated recess 24. Instead, the unit 10 is pushed into the cavity 18, and the angled face of each tooth 14 slides against the wall of its associated recess 24 thus causing the teeth 24 to move inwardly until they are within their recesses 24, when they spring out again into locking positions. In order to remove the unit 10 from the cavity 18, the buttons 25 are pushed towards each other and against the urging force, so as to retract the teeth 14 into release positions within the housing 12 and free of the recesses 24, thus allowing the unit 10 to be slid from the cavity 18. It will be appreciated that the unit 10 is thus easily and selectively removed from, and inserted into, the parking meter 16. It will be appreciated that the device 16 has a coin entrance slot that aligns with the entrance opening 30 when the unit 10 is in the cavity 18.
In a preferred embodiment of the invention, the unit 10 is electrically operable, and includes a set 26 of electrical spade connectors, which connectors are dimensioned and configured to connect to a complementary set of electrical socket connectors (not depicted) that are located in the body of the parking meter 16.
The invention extends, too, to a coin operated device 16 which includes a coin validation unit 10 in accordance with the invention, as described above. This aspect of the invention is best depicted in FIG. 3.
The invention extends still further to a coin-operated device 16 which includes a body 12 having a cavity 18 in which a removable coin validation unit 10 is receivable; a removable coin validation unit 10 in the cavity 18; and interoperable clip formations 14 on the body 12 and the coin validation unit 10.
It will be appreciated by the person skilled in the art that application of this invention is not limited to parking meters only, but that this invention also has application to a multitude of coin-operated machines, including parking lot pay-point machines, vending machines, jukeboxes and laundromat washing machines.
