The verti- I cal bar is adapted to be oscillated about its axis, thereby swing ing the said actuating arms .in a generally horizontal plane. However, theanns are so arranged on the bar. that only one of the arms will be in an operative position to operate its respective latch means. This will thus cause lateral movement of its respective latch means thereby rendering the same inoperable and permitting the shelf associated therewith to fall to its vertical nonsupporting position. i

Other objects and the attendant advantages of the present invention will become apparent from the detailed description 'to follow together with the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS There follows a detailed description of a preferred embodiment of the invention together with the accompanying drawings. However, it is to be understood that this description and the accompanying drawings are provided only for purposes of illustration and that the invention is capable of numerous modifications and variations apparent to those skilled in the art without departing from the spirit and scope of the invention.

FIG. 1 is a front elevational view of an article dispensing apparatus constructed in accordance with the features of the present invention. I

FIG. 2 is an elevational view taken from the one side of FIG. I but with the side cover plate removed.

FIG. 3 is a perspective view of a portion of the apparatus shown in FIGS. 1 and 2.

FIGS. 4A through 4D are schematic views taken in the same direction as FIG. 2 and showing various stages in the operation of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings wherein like numerals are employed to indicate like parts throughout. and referring in particular to FIGS. 1 through 3, there is shown a dispensing apparatus I having a rear partition 11, a main side partition 12 and an opposite side partition 12A. Mounted on the ap paratus are a plurality of shelves 13A, 13B and 13C. While only three shelves are shown in FIGS. 1 through 3, it will be understood that any number of shelves could be provided below shelf 13C. These shelves are of a length less than the distance between partitions 12 and 12A.

In the following description of the preferred embodiment, the terms tight" and left will be used for convenience and refer to the location of the elements as shown in FIGS. 1 and Further, a prime is employed to show the moved position of an element.

Each shelf includes a right side flange 14 and a left side flange 15. A support rod 16 extends along the rear partition 1 1 with its ends 17 and I8 protruding through side partitions 12 and 12A respectively. The rear of each shelf 13 is mounted on this rod 16 so that each shelf is mounted for rotational movement from a horizontal position to a vertical position. Each rod includes a spring 20 acting between an enlarged portion 19 on the support rod and the inside of flange 14 thereby urging the shelf 13 to the right to an extent limited by a spacing element 21 located on the rod 16. Each shelf also includes a latching means comprising a latch pin 22 rigidly connected at one end 23 to the bottom of its respective shelf 13 at a substantial distance along the shelf forward of the pivotal connection. This rod 22 passes through the side flange l4 and its other end 24 is adapted to pass through an aperture 25 in the partition 12. Thus, it will be seen that when the shelf 13 is urged to the right by spring 20 the rod 22 enters the opening 25 and thereby holds the shelf in the horizontal position. If the shelf is now urged to the left by a sufficient amount, the end 24 will pass to the left side of opening 25 and the shelf 13 will swing downwardly around rod 16. A spacing element in the form of spring 26 is provided at the left side of rod 16 to limit the leftward movement of the shelf 13 after the shelf has moved a sufficient amount to remove the end 24 of rod 22 from the opening 25.

To assure smooth downward movement of each article as it passes the lower shelves which have already been placed in the vertical condition, there is provided a deflector arrangement including a rear deflector 30 and a side deflector 31. In the illustrated embodiment, these two deflectors are formed integrally with each other and with an upper plate 32, the latter of which is welded or otherwise connected directly to rear partition 1 1.

To provide the selective lateral movement of the shelves 13 there is provided a control means comprising a vertical control bar extending vertically alongside all of the shelves. This bar includes a plurality of rearwardly extending arms 41. One arm is provided for each shelf. Thus, in FIGS. 1 through 3, three pins are illustrated, namely 41A, 41B and 41C. These are best illustrated in FIG. 2.

This bar includes elements 44 through (which will be explained in greater detail below) for oscillating this bar through a slight angle. This angle is illustrated in FIG. 3 between the two arms 41B and 41C and the phantom line representations of the moved positions of the arms, namely 41B and 41C. The effect of the movement of the arm 41C is to move the shelf 13C to the left as illustrated by the phantom line side flanges l4 and 15. This distance is sufficient for the end 24 of rod 22 to pass to the right-hand side of partition 12. Consequently, the rod 22 is no longer held in the horizontal position by aperture 25, and the shelf 13C swings downwardly about rod 16 to the vertical position as illustrated by arrow X in FIG. 3, and moved position 13C in FIG. 1.

A feature of the invention is the spacing between the arms 41. Assuming that the shelf 13C is in fact the lowermost shelf, then at the starting position the arm 41C will rest on the rod 22. Concurrently, the rod 418 will be spaced a distance H (FIG. 2) above its corresponding rod 22 on shelf 138. Similarly, the rod 41A will be spaced a distance 2H above its rod 22 on shelf 13A. Stating this relationship more generally, for any number of shelves, when the lowermost shelf rests on its pin 22, the second from the lowest shelf will be spaced a distance H above its pin 22 and all higher arms will be spaced 'a distance (rt-l H above their respective pins 22 wherein n" is an integer representing the number of that shelf counting up from the bottom shelf, for which n=l.

An actuating arm is considered to be in its operative" position when it rests on its respective pin 22. When in this operative position, as illustrated in FIGS. 2 and 3 for arm 41C, swinging movement of the rod 40 will swing the arm 41C against flange 14 of the shelf 13C thereby moving this shelf to the left as indicated at 14' and 15 in FIG. 3 so that the shelf will fall in the manner described above, thereby releasing the article mounted on that shelf to be dispensed through an opening located below the shelves.

As the arm 41C swings to the left, all higher pins swing above their respective shelves so that they do not urge their respective shelves to the left. After the shelf 13C has fallen to the vertical position, and after the rod 40 has been turned back to its original position, the rod 40 will drop downwardly until the arm 41B engages its respective rod 22 in preparation for the next actuation (oscillation) of rod 40. Since the arm 41A was located a distance 2H above its pin 22, it will now move down to a distance H, still above the level of its shelf 13A. After actuation of the bar 40 to operate shelf 138, the rod 40 will fall downwardly once again until arm 41A engages its respective rod 22 in preparation for operation of shelf 13A. After shelf 13A is in fact operated by oscillation of bar 40, the bar will fall downwardly until its horizontal bent portion 44 engages a fixed stop member 51.

It is important to note that the downward movement of the bar 40 will continue until one of its arms 41 engages its respective pin 22. However, this need not be the next highest shelf to that which was just actuated. For example, assume that it is desired to dispense an article which requires a space greater than that provided between two adjacent shelves but less than that provided between three adjacent shelves. Such articles could be dispensed by initially employing only every other shelf, leaving the intermediate shelves in the vertical position. Assume that such an article is placed on the shelf 13C and that shelf 13B is initially placed in the vertical condition. Then, after movement of arm 41C to lower the shelf 13C, the rod 40 will start its downward movement. However, the pin 22 of the shelf 13B is no longer in the path of arm 418 so that arm 41 8 will continue to move downwardly. This downward movement will continue to move downwardly. This downward movement will continue until the arm 41A engages and rests upon it respective pin 22 of the shelf 13A. Thus, the control means, after lowering a shelf, moves automatically to the next shelf which happened to be in the horizontal article-supporting position whether or not that is the next adjacent shelf.

Although it is believed that the operation of the invention is clear from the foregoing description of the preferred embodiment, nonetheless the operation of the invention will be described below with reference to schematic FIGS. 4A through 4D. In this illustration shelf ISD is provided in addition to shelves 13A through 13C. Further, referring to FIG. 4A, in the initial position only shelves 13A, 13C and 13D will be utilized to support articles. This might be the case where an extra tall article is placed on the shelf BC. In these FIGS., the partition 12 is not shown but the apertures 25 are indicated diagrammatically by circles.

rested uponits respective pin 22. Between FIGS. 48 and 4C the bar is once again oscillated. Arm 4lC' thereby moves shelf 13D to the left, causing the same to drop to-the position shown in FIG. 4C. The bar40 then drops until the next highest shelf which happens to be in a horizontal position, namely theshelf -l3A, is engaged by its respective arm 41A. Sincethe shelf 13B wasin'a vertical position before the actuation of shelf 13C, then its pin 22 was alreadyout of the path of arm 4lB sothat arm 41B continues its downward movement unobstructed until the pin 41A engages its respectivepin 22.-Between FIGS. 4C and 4Dthe: bar is once again oscillatedthereby causing the shelf 13A torbe lowered and permitting the bar 40 to fall until its upper bent'portion 44 engages the fixed stop 51.

It can be seenthat articles falling-from the upper shelves might well become snaggcdin thes'helves already placedin the vertical position or in the latch means 'for the lower shelves. The deflectors 30 and 3t assure the smooth downward movement of the articles and prevent the-possibilityofsnagging'. w f t R= f FIGS. 1 and 2 illustrate the mechanismfor causing the said oscillating movement of the bar 40. The bar :40 includes-a horizontally bent portion 4.4 and an upper vertical'portion 45,

which extends through the bottom'of a U-shaped clamp.46

A dispensing'apparatus according to latch means of each shelf is-horizontally'rnovable between an 48 and partition 50causes return movement of the elements art without departing from thespirit and scopeof the invention as defined in the claims.
