Description
33~
FIELD_OF_THE_INVENTION
The present invention relates to a dispensing device in which a loading chute is adapted to feed articles to a rotating dispensing mechanism which through its rotation takes the articles from the loading chute to an opening through which the articles are dispensed.
_ACKGROUND OE THE INVENTION_____________________ There are presently available many different types of dispensing machines most of which have complicated inte~nal mechanisms to provide for the dispensing of articles from the machines. These complicated mechanisms are often subject to premature breakdowns resulting in inefficient operation and frequent maintenance to the machines.
According to most applications these dispensing machines are coin operated and coin operated vending machines have two further common drawbacks in addition to those described above. Firstly, many of the coin operated vending machines will accept coins even when the machines are empty so that the coin is lost without any articles being dispensed from the machine to the user.
Secondly, some coin operated vending machines are subject to constant pilfering because the article loading region is reachable through the dispensing opening without requiring the insertion of a coin into the machines.
SUMMARY_OF_THE_PRE~ENT_INVENTION
The present invention provides a dispensing device comprising a rotatable operating member moveable from an initiate position through an operate position to operate ~0 dispensin~ means which rotates for dispensing articles ( 3'r~2 1 from the dispensing device, a chute for loading the articles in the device and Eor feeding the articles to the dispensing means and a locking member which moves along the chute as the articles are fed to the dispensing means. The locking member is adapted to move to a locking position for engaging the dispensing means and for preventing its rotation ~hen the chute has been emptied. The operating member is held away from the initiate position when the locking member moves to the locking position to indicate that the chute requires further loading.
The system is extremely simple with very few moving components which substantially reduces the likelihood of any breakdowns within the device. In fact, the device is preferably set up such that the feed to and from the dispensing means is strictly gravity operated, further decreasing the likelihood of malfunctions.
According to an aspect of the invention the dispensing device is set up for coin operation. According to this aspect a coin opening is provided on and carried with the rotatable operating member. The coin opening is positioned on the operating member such that it is accessible to an appropriate coin when the operating member is in the initiate position. When the operating member is held away from the initiate position by the locking member the coin opening is inaccessible to the same appropriate coin so that the coin cannot be lost in the machine after it has been emptied.
The device may used to dispense a plurality of different types of goods. By way of example, the device 3~3~
1 is used for the vending of both boxed sanitary napkins and individual tampons with the chute and the dispensing means being arranged to accommodate either of these two items.

DETAILED DESCRIPTION ACCORDING TO THE PREFERRED
EMBODIMENTS OF THE PRESENT INVENTION
The preferred embodiment structure shown in Figure 1 comprises a housing formed from a rearward box portion 1 and a forward door 5 adapted to close the box portion.
The internal dispensing mechanism of the device is located within the housing.
The housing further includes a flange region 3 at the open face of box 1 and a skirt 4 on the flange region. Door 5 is provided with a skirt 6 adapted to overlie skirt 4 when the door is closed to essentially eliminate unauthorized access to the internal dispensing mechanism. The box is further provided with catches 7 and 8 adapted to receive locking bars 9 controlled by swivel handle 10 on the door for locking the unit closed.
Provided interiorly of the housing is a vertically extending storage chute 13 with a rotating drum 21 provided immediately beneath the chute. A handle 17 is journalled to the drum and extends through opening 47 provided in door 5 when the door is closed. A coin insert having a coin receiving portion 19 is provided immediately above handle 17 such that the coin insert is also exposed through door opening 47. A coin guide 49 is provided on the door to facilitate the insertion of coins at the coin insert when the door is closed.
A dispensing chamber 43 is provided within the housing immediately beneath rotatable drum 21. When the door is closed chamber 43 is exposed through door opening 45 which aligns with the chamber. A coin receiving box 3~
1 51 is provided immediately beside chamber 43 within the housing.
Chute 13 although generally rectangular is provided with a pair of opposed channel regions 15 which are best seen in Figures 3 and 8. A locking member 33 also shown in Figures 3 and 8, but best shown in Figure 2 is adapted to slide downwardly within chute 13 guided by channel regions 15. This locking member which has a main body portion 41 is provided at its outer ends with a pair of lug portions 35. Each of these lug portions has opposed thin regions 37 facing upwardly in Figure 2 as well as opposed thicker regions 39 facing downwardly in Figure 2.
Referring to Figure 2a, rotating drum 21 is provided with an article receiving recess generally indicated at 23 and including a box receiving region 25 as well as a roll receiving region 27. Provided at the periphery of the rotating drum, away from the article receiving recess are a first pair of opposed slots 29 as well as a second pair of opposed slots 31. As can be seen in E'igure 2 slots 31 are slightly wider than slots 29 to cooperate with locking member 33 as described below.
Referring again to Figures 3 and 8, drum 21 is provided with a stem 22 connected directly through a supporting plate 20 to the rotating handle 17.
Therefore, when handle 17 is rotated drum 21 rotates with the handle.
~ andle 17 is locked against rotation until an appropriate coin is inserted into the coin slot 19 which releases a standard coin lock mechanism not shown in the drawings. The releasing of the coin lock mechanism 3~7~
1 allows rotating of handle 17.
In order to insert an appropriate coin into the coin insert 19, handle 17 must be in the zero or initiate position shown in Figures 3 and 8 because the coin insert rotates with handle 17 and once the handle is rotated away from the initiate position the coin insert is no longer accessible to the appropriate coin.
When there are articles stored in chute 13 handle 17 assumes the zero or initiate position through the coin lock mechanism which i5 spring loaded to move the handle to the zero position. This allows insertion of an appropriate coin into the dispenser without fear of the dispenser being empty. Furthermore, one very important feature of the present invention is that drum 21 in all positions of rotation completely blocks the lower end of chute 13 from the dispensing cavity 43 and door opening 45. This feature in combination with the tamper resistent construction of the housing makes the unit essentially pilfer-proof.
Figures ~ through 7 show the unit when used Eor the dispensing of the boxed napkins as indicated at N. These boxes are stored in chute 13 supported from beneath by drum 21 with locking member 33 sitting atop the upper most box in the chute. The locking member is positioned such that body portion 41 is supported by the boxes with lugs 35 fitted in the channels 15 to either side of the chute. The locking member is positioned such that the thinner lug portions 37 are turned downwardly for the dispensing of the napkins.
In Figure 4 coin C is inserted into coin insert 19 1 allowing handle 17 to be rotated away from the initiate position. At about 180 degrees rotation as shown in Figure 5 box receiving recess 25 is turned upwardly beneath the lower end of the chute such that the lower most napkin box falls into the box receiving region of the article recess. At the same time the remaining boxes move down a position with locking member 33 dropping down with the boxes. The lower end of the chute is covered by a shroud 26 which is bowed outwardly at 28 to allow the box in the drum to rotate away from the chute for continued rotation of handle 17 beyond the Figure 5 position with the napkin box being carried with the drum to the Figure 6 position where the napkins fall from the box receiving region down into cavity 43. As will be seen in Figure 6 drum 21 continues to rotate when there are further napkins in the chute so that handle 17 can be rotated slightly beyond the Figure 6 position back to the zero position of Figure 4.
However, once the final napkin box has been dispensed as shown in Figure 7, there is nothing to block the locking member away from the drum and therefore lug portions 37 of locking member 33 drop down into the peripheral slots 29 on drum 21. This locks the rotating drum and holds handle 17 and coin insert 19 away from the zero position making the coin insert totally inaccessible to the insertion of further coins into the unit. As will be seen in Figure 7 the locking of the drum does not occur until the drum has been rotated such that the last napkin box has cleared beyond shroud portion 26 allowing the box to drop down into the dispensing cavity.
3~2 1 When the unit is used to dispense tampons as shown in Figures 9 through 12 the tampons which are slightly wider than the napkin boxes, are Eitted directly into channels 15 of chute 13. Furthermore locking member 33 is reversed such that the wider lug portions 39 of the locking member are turned downwardly. Tbese lug portions seat directly atop the tampons which are again supported from beneath by drum 21.
The dispensing of the tampons T is generally the same as the dispensing of the napkins described above with the exception that the actual movement of the tampons to cavity 43 is slightly retarded relative to the napkin dispensing and as such the locking of drum 21 during the dispensing of the last tampon must also be slightly retarded.
More specifically, when the tampons are loaded in the chute as described above, and with handle 17 in the Figure 9 coin receiving position, coin insert lg is accessible to an appropriate coin. AEter the coin is inserted the handle can be released to rotate drum 21 such that the article receiving recess is exposed to the stacked tampons. The lowermost tampon rides over the relatively narrow box receiving region to the cut away roll receiving region 27 where the tampon drops down into a dispensing position. It will be noted that the dispensing position for the tampon is rearward of the dispensing position for the napkins producing the retarded dispensing mentioned aboveO Continued rotation of the drum to the Figure 11 position results in the tampon dropping from the drum into the dispensing 3c~
1 cavity. The handle is then released and the spring in the coin lock mechanism automatically returns the handle to the Figure 9 position as long as there are further tampons in the chute blocking the locking member away from the drum.
During the dispensing of the final tampon from the dispenser chute 13 is emptied as the tampon falls down into the roll receiving recess so that the lug portions 39 of locking member 33 ride on the periphery of the drum. The drum is rotated in order to move the tampon to the dispensing cavity past shroud 26. Premature locking of the lug portions into slots 29 which would otherwise prevent the clearing of the tampon past the shroud is prevented by virtue of the downward positioning of thick lug portions 39 which ride over the thinner peripheral slots. This allows the drum to be rotated far enough to drop the tampon into the dispensing cavity as shown in the Figure 12 position. At the same time that the tampon is dropped from the drum lug portions 39 align with the wider peripheral slots 31 which are adapted to receive the thicker lug portions and lock the drum in the Figure 12 position. As will be seen, the coin insert is held away from the coin insert position so that no further coins can be placed in the unit after it has been emptied.
With both the napkins and the tampons the principle of operation is the same i.e. to hold the coin insert away from the coin receiving position when the chute is empty although the positioning of operating handle 17 is slightly different from one application to the other.
According to the napkin dispensing arrangement the handle 1 is prevented Erom rotating a full 360 degrees so that it cannot ret~rn to the initiate position whereas according to the tampon dispensing arrangement the handle is rotated beyond 360 degrees and prevented from returning to the 360 degree position by the locking member.
As will be seen from the description above, the dispensing system of the present invention is extremely simple requiring very few moving components making it inexpensive from both a manufacturing as well as a maintenance standpoint. Furthermore, the system when used in a coin operated vending machine is essentially pilfer-proof while at the same time being adapted to assure that coins cannot be lost in the unit when all the articles have been dispensed resulting in customer satisfaction.
Although various preferred embodiments of the invention have been described herein in detail it will be appreciated by those skilled in the art that variations may be made thereto without departing from the spirit of the invention or the scope of the appended claims.

DETAILED DESCRIPTION ACCORDING TO THE PREFERRED
EMBODIMENTS OF THE PRESENT INVENTION
The preferred embodiment structure shown in Figure 1 comprises a housing formed from a rearward box portion 1 and a forward door 5 adapted to close the box portion.
The internal dispensing mechanism of the device is located within the housing.
The housing further includes a flange region 3 at the open face of box 1 and a skirt 4 on the flange region. Door 5 is provided with a skirt 6 adapted to overlie skirt 4 when the door is closed to essentially eliminate unauthorized access to the internal dispensing mechanism. The box is further provided with catches 7 and 8 adapted to receive locking bars 9 controlled by swivel handle 10 on the door for locking the unit closed.
Provided interiorly of the housing is a vertically extending storage chute 13 with a rotating drum 21 provided immediately beneath the chute. A handle 17 is journalled to the drum and extends through opening 47 provided in door 5 when the door is closed. A coin insert having a coin receiving portion 19 is provided immediately above handle 17 such that the coin insert is also exposed through door opening 47. A coin guide 49 is provided on the door to facilitate the insertion of coins at the coin insert when the door is closed.
A dispensing chamber 43 is provided within the housing immediately beneath rotatable drum 21. When the door is closed chamber 43 is exposed through door opening 45 which aligns with the chamber. A coin receiving box 3~
1 51 is provided immediately beside chamber 43 within the housing.
Chute 13 although generally rectangular is provided with a pair of opposed channel regions 15 which are best seen in Figures 3 and 8. A locking member 33 also shown in Figures 3 and 8, but best shown in Figure 2 is adapted to slide downwardly within chute 13 guided by channel regions 15. This locking member which has a main body portion 41 is provided at its outer ends with a pair of lug portions 35. Each of these lug portions has opposed thin regions 37 facing upwardly in Figure 2 as well as opposed thicker regions 39 facing downwardly in Figure 2.
Referring to Figure 2a, rotating drum 21 is provided with an article receiving recess generally indicated at 23 and including a box receiving region 25 as well as a roll receiving region 27. Provided at the periphery of the rotating drum, away from the article receiving recess are a first pair of opposed slots 29 as well as a second pair of opposed slots 31. As can be seen in E'igure 2 slots 31 are slightly wider than slots 29 to cooperate with locking member 33 as described below.
Referring again to Figures 3 and 8, drum 21 is provided with a stem 22 connected directly through a supporting plate 20 to the rotating handle 17.
Therefore, when handle 17 is rotated drum 21 rotates with the handle.
~ andle 17 is locked against rotation until an appropriate coin is inserted into the coin slot 19 which releases a standard coin lock mechanism not shown in the drawings. The releasing of the coin lock mechanism 3~7~
1 allows rotating of handle 17.
In order to insert an appropriate coin into the coin insert 19, handle 17 must be in the zero or initiate position shown in Figures 3 and 8 because the coin insert rotates with handle 17 and once the handle is rotated away from the initiate position the coin insert is no longer accessible to the appropriate coin.
When there are articles stored in chute 13 handle 17 assumes the zero or initiate position through the coin lock mechanism which i5 spring loaded to move the handle to the zero position. This allows insertion of an appropriate coin into the dispenser without fear of the dispenser being empty. Furthermore, one very important feature of the present invention is that drum 21 in all positions of rotation completely blocks the lower end of chute 13 from the dispensing cavity 43 and door opening 45. This feature in combination with the tamper resistent construction of the housing makes the unit essentially pilfer-proof.
Figures ~ through 7 show the unit when used Eor the dispensing of the boxed napkins as indicated at N. These boxes are stored in chute 13 supported from beneath by drum 21 with locking member 33 sitting atop the upper most box in the chute. The locking member is positioned such that body portion 41 is supported by the boxes with lugs 35 fitted in the channels 15 to either side of the chute. The locking member is positioned such that the thinner lug portions 37 are turned downwardly for the dispensing of the napkins.
In Figure 4 coin C is inserted into coin insert 19 1 allowing handle 17 to be rotated away from the initiate position. At about 180 degrees rotation as shown in Figure 5 box receiving recess 25 is turned upwardly beneath the lower end of the chute such that the lower most napkin box falls into the box receiving region of the article recess. At the same time the remaining boxes move down a position with locking member 33 dropping down with the boxes. The lower end of the chute is covered by a shroud 26 which is bowed outwardly at 28 to allow the box in the drum to rotate away from the chute for continued rotation of handle 17 beyond the Figure 5 position with the napkin box being carried with the drum to the Figure 6 position where the napkins fall from the box receiving region down into cavity 43. As will be seen in Figure 6 drum 21 continues to rotate when there are further napkins in the chute so that handle 17 can be rotated slightly beyond the Figure 6 position back to the zero position of Figure 4.
However, once the final napkin box has been dispensed as shown in Figure 7, there is nothing to block the locking member away from the drum and therefore lug portions 37 of locking member 33 drop down into the peripheral slots 29 on drum 21. This locks the rotating drum and holds handle 17 and coin insert 19 away from the zero position making the coin insert totally inaccessible to the insertion of further coins into the unit. As will be seen in Figure 7 the locking of the drum does not occur until the drum has been rotated such that the last napkin box has cleared beyond shroud portion 26 allowing the box to drop down into the dispensing cavity.
3~2 1 When the unit is used to dispense tampons as shown in Figures 9 through 12 the tampons which are slightly wider than the napkin boxes, are Eitted directly into channels 15 of chute 13. Furthermore locking member 33 is reversed such that the wider lug portions 39 of the locking member are turned downwardly. Tbese lug portions seat directly atop the tampons which are again supported from beneath by drum 21.
The dispensing of the tampons T is generally the same as the dispensing of the napkins described above with the exception that the actual movement of the tampons to cavity 43 is slightly retarded relative to the napkin dispensing and as such the locking of drum 21 during the dispensing of the last tampon must also be slightly retarded.
More specifically, when the tampons are loaded in the chute as described above, and with handle 17 in the Figure 9 coin receiving position, coin insert lg is accessible to an appropriate coin. AEter the coin is inserted the handle can be released to rotate drum 21 such that the article receiving recess is exposed to the stacked tampons. The lowermost tampon rides over the relatively narrow box receiving region to the cut away roll receiving region 27 where the tampon drops down into a dispensing position. It will be noted that the dispensing position for the tampon is rearward of the dispensing position for the napkins producing the retarded dispensing mentioned aboveO Continued rotation of the drum to the Figure 11 position results in the tampon dropping from the drum into the dispensing 3c~
1 cavity. The handle is then released and the spring in the coin lock mechanism automatically returns the handle to the Figure 9 position as long as there are further tampons in the chute blocking the locking member away from the drum.
During the dispensing of the final tampon from the dispenser chute 13 is emptied as the tampon falls down into the roll receiving recess so that the lug portions 39 of locking member 33 ride on the periphery of the drum. The drum is rotated in order to move the tampon to the dispensing cavity past shroud 26. Premature locking of the lug portions into slots 29 which would otherwise prevent the clearing of the tampon past the shroud is prevented by virtue of the downward positioning of thick lug portions 39 which ride over the thinner peripheral slots. This allows the drum to be rotated far enough to drop the tampon into the dispensing cavity as shown in the Figure 12 position. At the same time that the tampon is dropped from the drum lug portions 39 align with the wider peripheral slots 31 which are adapted to receive the thicker lug portions and lock the drum in the Figure 12 position. As will be seen, the coin insert is held away from the coin insert position so that no further coins can be placed in the unit after it has been emptied.
With both the napkins and the tampons the principle of operation is the same i.e. to hold the coin insert away from the coin receiving position when the chute is empty although the positioning of operating handle 17 is slightly different from one application to the other.
According to the napkin dispensing arrangement the handle 1 is prevented Erom rotating a full 360 degrees so that it cannot ret~rn to the initiate position whereas according to the tampon dispensing arrangement the handle is rotated beyond 360 degrees and prevented from returning to the 360 degree position by the locking member.
As will be seen from the description above, the dispensing system of the present invention is extremely simple requiring very few moving components making it inexpensive from both a manufacturing as well as a maintenance standpoint. Furthermore, the system when used in a coin operated vending machine is essentially pilfer-proof while at the same time being adapted to assure that coins cannot be lost in the unit when all the articles have been dispensed resulting in customer satisfaction.
Although various preferred embodiments of the invention have been described herein in detail it will be appreciated by those skilled in the art that variations may be made thereto without departing from the spirit of the invention or the scope of the appended claims.
