The invention relates generally to packing meters, and more particularly to a novel disconnectible hinge construction for quick removal of the meter compartment door by an authorized person.

Certain conventional parking meters have an upper meter compartment and a lower coin collectng compartment, the doors for both compartments being hinged on a pin located between the compartments. In many parking meters, some of the meter mechanism is a part of or is iixedly mounted on the inside of the meter compartment door, so that in replacing the meter it is necessary to remove the door and meter as a unit, and this requires removal of the hinge pin.

The hinge pin cannot be made removable from outside of the meter housing because in such case an unauthorized person could break into the meter; nor should the hinge pin be made removable from within the meter compartment because this would give access to the coin compartment, and in many localities the meter maintenance man is denied access to the coin compartment and it is accessible only to an authorized collector.

Accordingly, removal of the hinge pin should be made possible only from within the coin compartment, in which case the presence of both the meter maintenance man and the authorized collector would be required. Moreover, where the hinge pin is held in place by a set screw located within the coin compartment, the presence of a coin box carried on the coin compartment lid makes the set screw diliicult of access.

It is an object of the present invention to provide a novel hinge construction which is easily disconnectible from within the meter compartment without requiring or giving access to the coin compartment.

A further object is to provide a novel hinge construction in which the hinge pin for the meter compartment door and coin compartment door need not be removed in order to remove the meter compartment door.

Another object is to provide a novel disconnectible hinge construction for a meter compartment door in which the door in open position may quickly be disconnected from the hinge.

Another object is to provide a novel quickly disconnectible hinge construction for a parking meter door, which is inaccessible from the exterior of the meter housing and easily operable from within the meter compartment.

A still further object is to provide a novel 10 Claims. (Cl. 16-175) quickly disconnectible hinge construction for a parking meter door which is easily applied to conventional parking meter constructions.

These and other objects are accomplished by the parts, constructions, arrangements and combinations comprising the present invention, the nature of which is set forth in the following general statement, a preferred embodiment of which is disclosed in the accompanying drawings and specification as exemplifying the best known mode of carrying out the invention, the scope of the invention being defined in the appended claims.

In general terms, the invention is applied to a parking meter housing having an upper meter compartment door and a lower coin compartment door hinged on a pin located between the doors, and includes a laterally removable clip inserted around one end of the hinge pin between a hinge 'ear of the meter compartment door and the housing, said door being slidable axially on the pin when the clip is removed, to detach the opposite hinge ear of the door from the other end of the pin, and the hinge pin hole in said rst ear of the door being enlarged to permit swinginer the opposite ear laterally away from the oppcsite end. of the hinge pin for removing the door therefrom.

Referring to the drawings in which a preferred embodiment of the invention is shown by way of example;

Figure l is a fragmentary front elevation of a parking meter embodying the invention, showing the hinge connection between the upper meter compartment door andthe lower coin compartment door;

Fig. 2 is a similar view with the meter compartment door entirely removed;

Fig. 3 is a fragmentary side elevation showing the meter compartment door swing about the hinge pin to fully open position; Fig. 4 is an expanded view similar to Fig. 3, showing the door removed and the locking clip also removed;

Fig. 5 is a fragmentary plan sectional view through the meter compartment with the door swung to fully open position and the locking clip Similar numerals refer to similar parts throughout the drawings.

ln the drawings, the housing of the parking meter is indicated generally at 9, and has an upper meter compartment Iii having a door il, and a lower coin compartment door l2. The door i l has side anges ll hinged at their lower ends on a horizontal hinge pin I3, and the door I2 is hinged at its upper' end on the same pin i3, the door H being adapted for swinging outwardly downward as indicated in Fig. 3, and the door i2 being adapted for swinging outwardly upward.

Between the meter mechanism compartment and the coin compartment, the housing is provided with forwardly extending side walls I4 which terminate in forwardly projecting laterally spaced ears Mia and l5b in which the hinge pin is mounted. As best shown in Figs. 2 and 4., the ears i554 and lEb are offset laterally inwardly of the walls l5.. The coin compartment door i2 is provided with a central upwardly extending ear l@ which is pivoted on the central portion of the hinge pin, and a set screw (not shown) may be screwed through the ear ll from within the coin compartment to engage the hinge pin i?! and prevent its removal.

As shown in Fig. 2, a recess IIb is provided in the housing wall It around one end of the hinge pin I3, to allow a rounded boss or hinge ear I8?) on the flange II' in one side of the door Il to fit against the adiacent housing ear I5b, as indicated in Figs. 5 and 6. A similar recess ila is formed in the other housing wall I4, but the recess I'Ia is extended through the top of the housing wall for a purpose to be described. As shown in Figs. 5. 6 and 7, the rounded boss or hinge ear ma on the opposite side of the door is cut off substantially flush with the other side flange Il", so that when the door is in connected position a space is provided between the boss lila and the adiacent housing ear |511. The hinge pin i3 is extended suiciently beyond the ear Hifi to extend' across the space between the ear Ita and the ear Ia and have its outer end journaled in the ear [8a.

` As best shown in Fig. 2, the tops of the housing ears i511 and I5b are connected by a vertical plate and transverse web portion 20 and a partition wall 2l rests on top of the web and the housing walls i4. As shown in Figs. 5, 6 and 7 the front end of the partition wall 2l may be secured to the web 20 bv screws Z2. The partition wall separates or divides the meter mechanism compartment from the coin compartment and a coin receiving slot 23 may be provided in the partition wall for receiving coins discharged from the meter mechanism and discharging them into the coin compartment. As shown in Figs. 2 and 5, the housing walls around the meter compartment I!! may be provided with a gasket 24 against which the inner edges of the door anges il seat to make a tight seal.

The novel means for making the meter compartment door Il quickly removable, by an authorized person having access to the interior of said door, preferably includes a locking clip 26 which normally occupies the space between the housing ear Iba and the hinge ear I 8a of the door. when the door is in place as in Figs. l and 5. The C1110 25 is made With a lower hook portion 2l which fits around the extended end portion of the hinge pin I3, and the upper end 2a of the clip terminates at the top of the housing wall I4 and at the bottom surface of the partition. Well. 2l.

as best shown in Fig. 3. The upper portion 28 of the clip is provided with a narrow slot 29 for wedgeably engaging the blade 30 of a screw driver or the like, as indicated in Fig. 4, to facilitate quick removal of the clip when the meter door II is in open position. However, the clip may be removed with the fingers although not as conveniently.

In order to remove the door II and the meter mechanism attached thereto when the door is in the open position as shown in Fig. 5, the locking clip is first removed by inserting the blade 30 in the slot 29 and lifting the clip outwardly and upwardly. With the clip removed, the door II may be manually moved axially of the hinge pin to the right, whereupon the hinge ear ISb of the door will be moved so that the hinge pin hole 32 therein is moved beyond and free of the end of the hinge pin. i

The hinge pin hole 33` which is provided in the hinge ear Ia is slightly tapered or enlarged as shown, so that when the hinge ear |812 is thus moved free of the other end of the hinge pin, the door II may be swung laterally with the extended end of the hinge pin still pivoted in the hinge ear Ita in the manner indicated in Fig. 6. After the ear ISD is swung in this fashion to crear the housing ear Ib, the door is then moved manually to' the left, as in Fig. 7, to disengage the hole 33 from the extended end of the hinge pin, whereupon the door is entirely disconnected, and the door with the meter mechanism attached thereto may be removed as a unit, and replaced. V

The disconnectible hinge construction comprising the present invention is easily applied to a conventional parking meter, for making the meter compartment door quickly removable by the maintenance orY repair man who has access to the meter compartment. All that is necessary to make the application is to shift the hinge pin i3 bodily to the left to provide a slightly extended portion on the left end, cut out lor extend upwardly the recess lla, enlarge the hole 33, and cut 01T the ear or boss Ida on the door, so as to provide the space for receiving one of the locking clips 26. It is understood that the hinge pin I3 will be secured in its shifted position as by a set screw screwed through the ear I6 from within the coin compartment, so that the hinge pin cannot be removed from the exterior of the meter or from within the meter compartment.

Accordingly, the novel disconnectible hinge construction provides for quick removal of the meter compartment door only by an authorized person who has access to the meter compart-l ment, without giving access to or affecting in any way the coin compartment or the coin compartment door. Moreover, the meter compartment door may be disconnected and removed without the use of special tools, and may be accomplished by the use of an ordinary screw driver, or merely by using the fingers if no screw driver is available. The novel hinge construction is simple and economical to make, and extremely easy to operate.

ln the foregoing description, certain terms have been used for brevity, clearness and understanding, but no unnecessary limitations are to be implied therefrom beyond the requirements of the prior art, because such words are used foi` descriptive purposes herein and are intended to be broadly construed.

Moreover, the embodiment of the improved construction illustrated and described herein is by way of example, and the scope 0f the present invention is not limited to the exact details of construction.

Having now described the invention, the construction, the operation and use of a preferred embodiment thereof, and the advantageous new and useful results obtained thereby; the new and useful constructions, and reasonable mechanical equivalents thereof obvious to those skilled in the art, areset forth in the appended claims.
