DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Turning first to Figure l, there is shown the centerflow dispenser 10 of the present invention. The 4b centerflow dispenser 10 includes a wall mounting plate 12 (shown in Fig. 2 and 3.) which has affixed thereto and extending 90 degrees out therefrom lower housing or support member 14. Providing additional structural integrity for lower housing or support member 14 are brackets 16 which extend outwardly from wall mounting plate 12.
The dispenser 10 of the present invention is provided with a door or front housing 18 which pivotally connects to lower housing 14 by means of pins 20. Door or front housing 18 includes a top or lid section 22 and the side sections 23. Thus when a rolled paper product 25 is placed on lower housing 14 and door or front housing 18 is closed, the rolled paper web 25 is substantially enclosed such that access to the web is only through the lower exit port 24 ( see Fig. 4 ) in support member or lower housing 14 .
Lower housing 14 is comprised of lower wall 26 having peripheral wall member 28 extending upwardly therefrom and cover or lid 30. Lower wall 26 is attached to cover or lid 30 by means of screws 32.
Attachment of cover 30 to lower wall 26 creates a chamber 34 within lower housing 14. Contained within chamber 34 is drawer 35. There is a disk 38 rotatably attached to drawer 36 by means of pin 40. Disk 38 has a plurality of dispensing orifices 39 disposed in the 'r periphery thereof. The dispensing orifices 39 vary in diameter.
As shown more clearly in Figure 4, lower wall 26 of lower housing I4 has guide members 42 extending upwardly therefrom. That area of chamber 34 between guide numbers 42 provide a residence for drawer 35.
Drawer 36 includes a peripheral lip 44 extending upward from a planar surface 4S. Peripheral lip 44 is greater in height than the thickness of disk 38. The width of lip 44 is substantially equal to the height of guide members~42. In such manner, it is assured s p ;) fr ~ ~~ ~ ~ U if that when cover 30 is mounted to lower wall 26, cover 30 will not bind disk 38 to such extent that disk cannot be easily, manually rotated. Also extending upward from lower wall 26 is stop member 46. Stop member 46 is preferably arcuate having a radius substantially similar to the radius of lower exit port 24.
Drawer 36 includes handle member 48 which extends through notch 50 in peripheral wall 28. Drawer 36 further includes hole 52 which has a diameter equal to or greater than the diameter of the largest of orifices 39 in disk 38. Extending from hole 52 in drawer 36 is V-shaped opening 54 such that the point of the "V" (or point of convergence), if projected would converge and terminate within hole 52. Although opening~54 is preferably V-shaped, the shape of opening 54 may be varied so long as the sides of opening 54 remain substantially divergent.
Cover 30 includes a circular recess 56 in which the rolled paper web 25 rests. The cylindrical diameter of the circular recess 56 should therefore, preferably, be equal to or greater than the diameter of the rolled paper web. Cover 30 includes an upper exit port 58 therethrough which is substantially concentric with circular recess 56. Extending downward from upper exit port 58 is tapered lip 60 - making upper exit port 58 funnelled or frusto-conical in shape. Upper exit port 58 is in substantial vertical alignment with lower exit port 24 and is of like diameter. When drawer 36 is fully inserted into chamber 34 between guide members 42, hole 52 overlaps or aligns nonconcentricly with~lowar exit port 24 and upper exit port 58. Disk 38 can be rotated such that each of the orifices 39 can be rotated into a position 3s to vertically overlap or align with hole SZ. Tapered lip 60 extends down to contact disk 38. Thus, although disk 38 can be manually rotated, th. contact between disk 38 and lip 60 as well as between disk 38 and drawer 36 ensures that there is resistance to the free spinning of disk 38. Drawer 36 and disk 38 are also provided with a detent arrangement to prevent unintentional rotation of disk 38. As shown in Figure 10, the bottom surface of disk 38 includes a series of indentations 86. Each indentation 86 is spaced 180°
from a particular orifice 39. As disk 38 is rotated to select an orifice 39, the indentation 86 opposite the selected orifice 39 will engage protuberance 88 on drawer 36 (see Figure 6). Therefore, once the desired orifice is. selected, the action of pulling the paper web 25 through exit gorts 24 and 58 will not impart rotational movement to disk 38.
To load the centerflow dispenser 10 of the present invention, door 18 is unlocked and pivoted downwardly thereby exposing handle 48 of drawer 36.
Handle 48 can thus be grasped and pulled outwardly ,from peripheral wall 28 thereby bringing V-shaped opening 54 in vertical alignment with lower exit port 24 and upper exit port 58. Arcuate extension 56 serves as a travel stop for drawer 36 when handle 48 is pulled outwardly thus insuring that all or at least a portion of selected orifice 39 will still reside in vertical alignment with lower exit port 24 and upper exit port 58. In such manner, a large opening is provided through which the lead end of the rolled paper web 25 can be easily inserted. Before the lead end of the paper web 25 is inserted, disk 38 is rotated to a position aligning the desired orifice 39 with hole 52. After the lead end of rolled paper web 25 has been pulled through, the user need only push handle 48 thereby driving drawer 36 back into fully inserted position in chamber 34. Therefore, the combination of drawer 36 and V-shaped opening 54 form a means for enlarging the opening through which th.
lead end of rolled paper web 25 is inserted when the ~~t~~~.~U~
dispenser of the present invention is loaded. This means for enlarging is a significant advantage when initially feeding the lead end of rolled paper web 25 through such opening when it is understood that the diameter of a dispensing arifice 39 may be on the order of 3/8 of an inch.The rolled paper web 25 can then be placed on cover 30 and door 18 closed. Aa drawer 36 is being closed, it may be necessary for the person loading the dispenser to bunch that portion of the lead end of paper web 25 which is in close proximity to the exit ports 24 and 58 toward hole 52 and selected orifice 39. This will aid in preventing a portion of the web 25 from being caught outside of selected orifice 39. However, it should be recagnized that the V-shaped opening 54 automatically promotes the bunching of the web 25 into hole 52 as drawer 36 is inserted.
Handle 48 and cover 30 are provided with ~ a locking detent mechanism (not shown). The detent mechanism prevents the forced exerted on drawer 36 during dispensing from urging drawer 36 against door 18 which, in turn, prevents V-shaped opening 54 from moving into overlapping vertical alignment with exit ports 24 and 58. Such movement of V-shaped opening 54 during dispensing could result in snagging of the web.
In the alternative, rather than providing handle 48 and cover 30 with a detent mechanism, drawer 36 can be spring biased to be urged into the closed position unless held in the open position by the operator.
Further, door 18 can be closely toleranced to reside in abutting relation with handle 48 upon tha closing of both door 18 and drawer 36 thus eliminating tho need foz the detent mechanism. In such manner, drawor 36 will be provided no room for lateral movesent during dispensing. If door 18 is ao closely toleranced to reside in abutting position with handy 48, then it may be desirable to spring bias drawor 36 such that it automatically opens upon the opening of door 38.
In the preferred embodiment, door 18 is provided with a closing rib 90 on the inside surface thereof.
(See Figures 11 ~ 12). If the operator attempts to close door 18 without first closing drawer 36, closing rib 90 will contact handle 48 and as door 18 is rotated to a closed position, closing rib 90 will urge handle 48 and drawer 36 to a closed position.
In an alternative embodiment an alternative drawer 60 can be used as shown in Figure 7. In such embodiment., drawer 60 includes a recessed lip 70, a hole 72 and~a U-shaped opening 74. Recessed lip 70 is adapted to receive U-shaped orifice member 76. There are a plurality of U-shaped orifice members 76 each having a different diameter restriction orifice 78 therethrough. U-Shaped orifice member 76 has extending downward therefrom key members 80 which insert into notches 82 in recessed lip 70 thus preventing movement of U-shaped member 76 relative to drawer 36.
Although the figures depict dispensing orifices 39 and 78 as being substantially circular, it should be recognized that dispensing orifices 39 and 78 could be any of a variety of geometric shapes such as, for example, elliptical or polygonal. Therefore, as used herein, the term diameter is defined as a chord passing through the center of a figure.
To accommodate the use of U-shaped orifice members 76 with drawer 60, cover 30 must include an opening 84 large enough such that U-shaped member can be inserted therethrough to reside on recessed lip 70. Once the U-shaped member 76 containing the desired orifice is selected, it is inserted through .
that keys 80 opening 84 and onto recessed lip 70 such engage with notches 82. Handle 48 can then be withdrawn aligning V-shaped opening ~4 with lower esit :~ ~ ~ ~'~ ~- '~
port 24 and opening 84. As with the first embodiment discussed above, this second embodiment allows for easy placement of the lead edge of the rolled paper web 25 through an enlarged opening. The drawer 60 can then be pushed inward such that the paper web becomes enclosed within the orifice of the selected U-shaped orifice member 76.
From the foregoing, it will seen that this invention is one well adapted to attain all of the ends and objects hereinabove set forth together with other advantages which are apparent and which are inherent to the apparatus.
It will be understood that certain features and subcombinations are of utility and may be employed with reference to other features and subcombinations.
This is contemplated by and is within the scope of the claims.
As many possible embodiments may be made of the invention without departing from the scope thereof, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

Lower housing 14 is comprised of lower wall 26 having peripheral wall member 28 extending upwardly therefrom and cover or lid 30. Lower wall 26 is attached to cover or lid 30 by means of screws 32.
Attachment of cover 30 to lower wall 26 creates a chamber 34 within lower housing 14. Contained within chamber 34 is drawer 35. There is a disk 38 rotatably attached to drawer 36 by means of pin 40. Disk 38 has a plurality of dispensing orifices 39 disposed in the 'r periphery thereof. The dispensing orifices 39 vary in diameter.
As shown more clearly in Figure 4, lower wall 26 of lower housing I4 has guide members 42 extending upwardly therefrom. That area of chamber 34 between guide numbers 42 provide a residence for drawer 35.
Drawer 36 includes a peripheral lip 44 extending upward from a planar surface 4S. Peripheral lip 44 is greater in height than the thickness of disk 38. The width of lip 44 is substantially equal to the height of guide members~42. In such manner, it is assured s p ;) fr ~ ~~ ~ ~ U if that when cover 30 is mounted to lower wall 26, cover 30 will not bind disk 38 to such extent that disk cannot be easily, manually rotated. Also extending upward from lower wall 26 is stop member 46. Stop member 46 is preferably arcuate having a radius substantially similar to the radius of lower exit port 24.
Drawer 36 includes handle member 48 which extends through notch 50 in peripheral wall 28. Drawer 36 further includes hole 52 which has a diameter equal to or greater than the diameter of the largest of orifices 39 in disk 38. Extending from hole 52 in drawer 36 is V-shaped opening 54 such that the point of the "V" (or point of convergence), if projected would converge and terminate within hole 52. Although opening~54 is preferably V-shaped, the shape of opening 54 may be varied so long as the sides of opening 54 remain substantially divergent.
Cover 30 includes a circular recess 56 in which the rolled paper web 25 rests. The cylindrical diameter of the circular recess 56 should therefore, preferably, be equal to or greater than the diameter of the rolled paper web. Cover 30 includes an upper exit port 58 therethrough which is substantially concentric with circular recess 56. Extending downward from upper exit port 58 is tapered lip 60 - making upper exit port 58 funnelled or frusto-conical in shape. Upper exit port 58 is in substantial vertical alignment with lower exit port 24 and is of like diameter. When drawer 36 is fully inserted into chamber 34 between guide members 42, hole 52 overlaps or aligns nonconcentricly with~lowar exit port 24 and upper exit port 58. Disk 38 can be rotated such that each of the orifices 39 can be rotated into a position 3s to vertically overlap or align with hole SZ. Tapered lip 60 extends down to contact disk 38. Thus, although disk 38 can be manually rotated, th. contact between disk 38 and lip 60 as well as between disk 38 and drawer 36 ensures that there is resistance to the free spinning of disk 38. Drawer 36 and disk 38 are also provided with a detent arrangement to prevent unintentional rotation of disk 38. As shown in Figure 10, the bottom surface of disk 38 includes a series of indentations 86. Each indentation 86 is spaced 180°
from a particular orifice 39. As disk 38 is rotated to select an orifice 39, the indentation 86 opposite the selected orifice 39 will engage protuberance 88 on drawer 36 (see Figure 6). Therefore, once the desired orifice is. selected, the action of pulling the paper web 25 through exit gorts 24 and 58 will not impart rotational movement to disk 38.
To load the centerflow dispenser 10 of the present invention, door 18 is unlocked and pivoted downwardly thereby exposing handle 48 of drawer 36.
Handle 48 can thus be grasped and pulled outwardly ,from peripheral wall 28 thereby bringing V-shaped opening 54 in vertical alignment with lower exit port 24 and upper exit port 58. Arcuate extension 56 serves as a travel stop for drawer 36 when handle 48 is pulled outwardly thus insuring that all or at least a portion of selected orifice 39 will still reside in vertical alignment with lower exit port 24 and upper exit port 58. In such manner, a large opening is provided through which the lead end of the rolled paper web 25 can be easily inserted. Before the lead end of the paper web 25 is inserted, disk 38 is rotated to a position aligning the desired orifice 39 with hole 52. After the lead end of rolled paper web 25 has been pulled through, the user need only push handle 48 thereby driving drawer 36 back into fully inserted position in chamber 34. Therefore, the combination of drawer 36 and V-shaped opening 54 form a means for enlarging the opening through which th.
lead end of rolled paper web 25 is inserted when the ~~t~~~.~U~
dispenser of the present invention is loaded. This means for enlarging is a significant advantage when initially feeding the lead end of rolled paper web 25 through such opening when it is understood that the diameter of a dispensing arifice 39 may be on the order of 3/8 of an inch.The rolled paper web 25 can then be placed on cover 30 and door 18 closed. Aa drawer 36 is being closed, it may be necessary for the person loading the dispenser to bunch that portion of the lead end of paper web 25 which is in close proximity to the exit ports 24 and 58 toward hole 52 and selected orifice 39. This will aid in preventing a portion of the web 25 from being caught outside of selected orifice 39. However, it should be recagnized that the V-shaped opening 54 automatically promotes the bunching of the web 25 into hole 52 as drawer 36 is inserted.
Handle 48 and cover 30 are provided with ~ a locking detent mechanism (not shown). The detent mechanism prevents the forced exerted on drawer 36 during dispensing from urging drawer 36 against door 18 which, in turn, prevents V-shaped opening 54 from moving into overlapping vertical alignment with exit ports 24 and 58. Such movement of V-shaped opening 54 during dispensing could result in snagging of the web.
In the alternative, rather than providing handle 48 and cover 30 with a detent mechanism, drawer 36 can be spring biased to be urged into the closed position unless held in the open position by the operator.
Further, door 18 can be closely toleranced to reside in abutting relation with handle 48 upon tha closing of both door 18 and drawer 36 thus eliminating tho need foz the detent mechanism. In such manner, drawor 36 will be provided no room for lateral movesent during dispensing. If door 18 is ao closely toleranced to reside in abutting position with handy 48, then it may be desirable to spring bias drawor 36 such that it automatically opens upon the opening of door 38.
In the preferred embodiment, door 18 is provided with a closing rib 90 on the inside surface thereof.
(See Figures 11 ~ 12). If the operator attempts to close door 18 without first closing drawer 36, closing rib 90 will contact handle 48 and as door 18 is rotated to a closed position, closing rib 90 will urge handle 48 and drawer 36 to a closed position.
In an alternative embodiment an alternative drawer 60 can be used as shown in Figure 7. In such embodiment., drawer 60 includes a recessed lip 70, a hole 72 and~a U-shaped opening 74. Recessed lip 70 is adapted to receive U-shaped orifice member 76. There are a plurality of U-shaped orifice members 76 each having a different diameter restriction orifice 78 therethrough. U-Shaped orifice member 76 has extending downward therefrom key members 80 which insert into notches 82 in recessed lip 70 thus preventing movement of U-shaped member 76 relative to drawer 36.
Although the figures depict dispensing orifices 39 and 78 as being substantially circular, it should be recognized that dispensing orifices 39 and 78 could be any of a variety of geometric shapes such as, for example, elliptical or polygonal. Therefore, as used herein, the term diameter is defined as a chord passing through the center of a figure.
To accommodate the use of U-shaped orifice members 76 with drawer 60, cover 30 must include an opening 84 large enough such that U-shaped member can be inserted therethrough to reside on recessed lip 70. Once the U-shaped member 76 containing the desired orifice is selected, it is inserted through .
that keys 80 opening 84 and onto recessed lip 70 such engage with notches 82. Handle 48 can then be withdrawn aligning V-shaped opening ~4 with lower esit :~ ~ ~ ~'~ ~- '~
port 24 and opening 84. As with the first embodiment discussed above, this second embodiment allows for easy placement of the lead edge of the rolled paper web 25 through an enlarged opening. The drawer 60 can then be pushed inward such that the paper web becomes enclosed within the orifice of the selected U-shaped orifice member 76.
From the foregoing, it will seen that this invention is one well adapted to attain all of the ends and objects hereinabove set forth together with other advantages which are apparent and which are inherent to the apparatus.
It will be understood that certain features and subcombinations are of utility and may be employed with reference to other features and subcombinations.
This is contemplated by and is within the scope of the claims.
As many possible embodiments may be made of the invention without departing from the scope thereof, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
