19 Claims. (Cl. 23243.4)

ABSTRACT OF THE DISCLOSURE A service compartment accessible by door means alter natively from one of two sides for respectively receiving an article or rendering the received article available for removal from the compartment. The compartment is provided with lock means, operable by key means. Thev key means becomes inaccessible for unauthorized use respon sive to the operation of the lock means for gaining access to the article disposed in the compartment and the subsequent motion of the door means.

This invention refers to service compartments and, more specifically, has reference to a service compartment adapted to receive an article which is to be rendered available to a patron in response to the patron providing an appropriate key means which operates door mean associated with the compartment.

This invention is related also to my copending applications for US. Letters Patent, Ser. No. 466,705 filed June 24, 1965, entitled, Service Compartment, now US. Patent No. 3,300,016 dated Jan. 24, 1967, and Ser. No. 598,027 filed Nov. 30, 1966, entitled, Article Delivery System, and is related further to my earlier US. Patent No. 3,130,395 dated Apr. 21, 1964, entitled, Service Area With Compartments.

Quite specifically, this invention relates to certain alternative design features and improvements which endow the service compartment disclosed hereafter with novel and unique features not disclosed in the patent and-applications stated heretofore.

With reference to the drawings: I

FIGURE 1 is a front and side perspective view of my new service compartment;

FIGURE 2 is an enlarged view of a portion of FIG- URE 1 showing the lock and key means in an alternative position;

FIGURE 3 is a top plan view, partly in FIGURE 1;

FIGURE 4 is a side elevational view along section line 4-4 in FIGURE 3; I

FIGURE 5 is a sectional view along line 55 in FIG- URE 4;

FIGURE 6 is a vertical section of the compartment taken along section line 66 of FIGURE 3;

FIGURE 7 is a schematic illustration showing the difsection, of

means of pins 14 and pillow blocks 15..The platform is adapted to receive and support thereupon an article A which may comprise a tray having a meal ordered by a patron. As seen in FIGURE 1, the front will be consid-, ered the side exposed to a patron while the opposite, rear, sidewillbe considered the compartment servicingside.

Referring still to FIGURE 1, the door 13 as shown is disposed in the closed position, preventing access to platform 12 from the patrons side, i.e. the front side. This closed position of the, door 13 is the first position and, while the door is,in this first position, no access is available to the interiorof the compartment from this first side. In. FIGURE 1, a lock means 16 associated with the door is covered by a :cover 17 and is not accessible, therefore, for operation by a patron who may be in receipt of an appropriate key by virtue of having ordered and paid for a m eal. The compartment is accessible, however, from the servicing side, second side, when the door 13 isin its first psition as is clearly evident in FIGURE 1 and, hence, the compartment can be provided with the purchased meal or article A. The arrow 18 points through the opening used for providing the article in the compartment.

When an article A, after having been prepared, is placed into the compartment from the servicing (second) side, one or more sensing switches S1 associated with the platform 12 sense such condition and the lock cover 17, previously precluding access to the lock means 16 since no article was present, snaps open as is shown in FIGURE 2. The lock cover 17 is mounted for pivotal motion to the frame 20, FIGURE 4, and a spring 21 engaging the .cover urges the cover toward its raised position, i.e. exposing the tumbler lock 16. When no article is on the compartment platform 12, sensing switch S1 is not actuated and a not-energized solenoid S2, by means of an associated latch 22, causes the cover 17 to be in closed position.

The tumbler lock 16, mounted for motion with the door 12, is operable by inserting an appropriate key which is issued to a patron. The lock 16 has fastened thereto a cam 25 which is attached to the lock plug and rotated in response to the lock plug being rotated by the key 26. When the door is locked in its first position, preventing access to the platform from the patron side, the condition shown in FIGURES l and 4, the cam 25 (solid lines FIG- URE 5) engages a spring biased lever 31, pivoting about a pin 32 and mounted to a bracket 33 which is aflixed to the stationary frame structure 10.

Proceeding now from the condition shown in FIGURE 2, that is an article being present in the compartment, the patron inserts a key 26 issued to him and rotates the lock to unlock the door for motion from its first position. The

cam 25 responsive to turning the key assumes the rotated ferent positions which the door means assumes during a cycle of operation;

FIGURE 8 depicts schematically an alternative construction of the door means;

FIGURE 9 is a schematic electrical circuit diagram, and

FIGURE 10 is an explanatory sketch showing the cam motion provided by the lock means.

Referring now to the figures and to FIGURES 1, 2, 3, 4 and 6m particular, there is shown a pedestal 10 which supports at a convenient distance from the floor level a service compartment 11. The compartment 11 includes as its main element a horizontal stationary platform 12 which is provided with an arcuate door means 13 having a front cover and two side plates and being mounted for pivotal motion relative to the platform and'pedestal by position shown by the dashed lines 25A in FIGURE 5. Also, the cam 25 when rotated to its unlocked position actuates the switch S6 which is fastened to the frame structure. For the moment, no action takes place until the patron recloses the spring biased cover 17, which condition is sensed by a switch S3, FIGURE 3. By virtue of this procedure, the patron no longer has access to the key which now. is hidden and inaccessible underneath the cover 17. A motor 27, FIGURE 4, by means of pulleys 28, 29 and a drive belt 30, is actuated and causes pivotal motion of the door 13 from its first position to its second position, the latter position being defined as the condition when the platform 12 is fully accessible from the patrons side for enabling removal of the article A while being closed off for access to the platform from the servicing side, the rear side.

Patented Oct. 29, 1968 pass past the pin 40, the cam and hence the plug of the lock is rotated by 90 degrees, causing the lock to resume its previous or normal position. The several stages of cam rotation in response to the passing of the cam past the stationary pin are indicated in FIGURE 10, steps A B and C. FIGURE 10A shows the condition when the rotated cam (unlocked lock) first encounters the pin 40, while FIGURE 10C shows the again normalized cam position.

The lock 16 is provided with a key ejection spring, such as is well known in the art, i.e. the key, unless depressed in the normal position, is ejected from the lock plug. As the lock plug is returned to its normal position, FIGURE 10C, at which time the lock with the door has travelled to the dashed position shown in FIGURE 4, the ejection spring of the lock ejects the key from the plug and the now ejected key is propelled into a conduit as indicated by the dashed arrow 46A in FIGURE 4. The key 26 falls onto a tray 46 which is on the servicing side of the compartment and thus the key is not accessible to the patron who meanwhile is gaining or has gained access to the article A. The key is available, however, to authorized personnel for return to the cashier. The door 13 reaches its fully second position at which time the edge of the arcuate door actuates the limit switch S4 which interrupts the motor drive circuit.

In order to reload the compartment with a new article, servicing personnel operating on the servicing side, rear side as seen in FIGURE 1, cause the door 13 to be returned to its first position, the position shown in FIG- URES 1 and 4. By virtue of the spring associated with the lever 31, the normalized cam 25 is able to depress the upstanding left edge of the lever, pass over the lever and thereafter latch as shown in FIGURE 5.

FIGURE 7 shows the three main conditions of the compartment. FIGURE 7A shows the door 13 in its first position, the lock cover 17 being open for access to the lock since an article A is present on the platform, FIG- URE 7B shows the condition of the compartment after, a patron has supplied the key, operated the lock and caused the door to assume its alternative second position. The article A is available to the patron while the opposite, servicing, side of the compartment is closed off. FIGURE 7C shows the compartment door 13 returned to its first position, the lock cover 17 covering the lock in order to prevent access to the lock and operation of the door since no article has as yet been deposited on the platform and, hence, no article is available for issuance to the patron.

FIGURE 9 is a schematic electrical circuit diagram. All switches, the solenoid and the relay are shown in position when the door 13 is in its first position and the compartment platform 12 is ready to receive an article. As an article, represented by the outline A, is placed on the platform, the sensing switch S1 is actuated, energizing the solenoid S2 which releases the lock cover 17, causing the cover to be raised. The open lock cover exposes the lock 16, FIGURE 2, and operates the switch S3, lowering the movable contact arm. When the patron inserts the appropriate key in the lock and rotates the plug for unlocking the door, the locking cam 25 associated with the plug moves out of the way and permits switch S6 to be closed, signifying that the door 13 has been unlocked. Closed switch S6 applies power via the lowered contact of switch S3 to the coil of the relay K1 which locks up via the associated contact *Kl-l and switch S4. Contact K1-3 removes power from the solenoid S2, permitting the lock cover to relatch when depressed hereafter. The key being turned in the lock is retained therein while the remaining control circuit is ready to be started for providing access to the article A.

In order to proceed, the cover 17 is manually depressed and relatches, thus applying power to the motor 27 via the closed switches S6, S3 and relay contact K1-2, causing the motor to run in a direction to pivot the compartment door from its first position to its second position. The door moves until it actuates the limit switch S4, actuation of which drops out the relay K1. The article then is available for removal by the patron. When a new article is ready to be placed upon the platform of the compartment, an attendant manually operates the switch S5, causing the compartment door to return to the closed position, ready for the next key holding patron.

If the door is to be returned to its first position fully automatically, responsive to the removal of the article A as sensed by the switch S1, a suitable relay is actuated for causing the motor to start and return the door 13 to its first position. -A limit sensing switch, similar in function to switch S4, will be provided to interrupt the motor circuit when the door reaches its end position.

An alternative compartment door design is shown in FIGURE 8. Two doors 60 and 61 are mounted for reciprocating motion to alternatively expose or close off one of the compartment sides. The doors are linked by a chain 62 driven by a motor 63 over sprockets 64, 65. As seen in FIGURE 8, the door 60 is closed and prevents access to the platform 70 from a first side while at the same time access is available from the opposite side, the door 61 being raised. Conversely, when the door 61 is lowered, the door 60 is raised and the reverse access condition to the platform 70 prevails. It will be apparent that instead of vertically moving doors, horizontally moving doors may be substituted without deviating from the principles disclosed.

In a further alternative embodiment the stationary platform may be replaced by a movable band which transports the article A onto the platform and also from the platform toward the patrons side out of the compartment.

While there has been described and illustrated a preferred embodiment of my invention and several modifications have been indicated, it will be apparent to those skilled in the art that various further changes and modifications may be made therein without departing from the broad principle and intent of this invention.
