Title: Dual roll toilet tissue dispenser

Description:
BACKGROUND OF THE DISCLOSURE 
     a) Field of the Disclosure 
     This disclosure relates to the field of dispensing sheet product, and in particular to dispensing rolls of toilet tissue. One form of the disclosure pertains to dual-roll dispensers wherein a plurality of rolls of product are disposed on a plurality of cores. In one example, the disclosure relates to dispensers wherein a primary roll is at a fixed position and a secondary roll is repositioned from a reserve position to a usable position when a primary roll is substantially consumed. In another example, the disclosure relates to dispensers wherein each roll is at a fixed position and the door is provided to allow access to a secondary roll when a primary roll is substantially consumed. 
     b) Background Art 
     Several dual-roll paper product dispensers have been conceived. These prior art references have varying degrees of applicability and varying degrees of success in restricting access to a secondary roll until a primary roll is substantially consumed, and often require many steps to gain access to consumed rolls to facilitate restocking. 
     SUMMARY OF THE DISCLOSURE 
     In general, the object of this disclosure is a paper product dispenser for dispensing a toilet paper roll wherein a first roll or primary roll of product can be accessed by a user and a secondary roll of product is held in reserve until the primary roll is substantially consumed. Whereas it was sometimes possible in prior applications to be able to access the secondary roll before the primary roll was completely consumed, this often resulted in undesired waste of product and in waste of time as a janitor or other person responsible for replacing the paper product would have to do so prematurely. 
     A mechanism is disclosed wherein a swing arm extends from a portion of the interior of the dispenser which engages the outer surface of the primary roll of product. In one embodiment, this swing arm includes a portion configured to frictionally rest upon the outer radius of the primary roll of product until the roll is completely consumed, at which point this portion extends radially inward beyond the outer radius of the core of the product and a release latch or seer mechanism is activated which allows a user to access the secondary roll of product. 
     In one embodiment, a casing door is provided which is a movable portion of the casing which in one position prohibits access to the secondary roll of product and a second position allows access to the secondary roll of product. As the release latch or seer mechanism is activated, the casing door repositions from the first position to the second position. 
     Another advantage of the embodiments disclosed herein is an option wherein the entire apparatus is reset as the casing comprises a portion which is pivotally mounted to a frame and connected to a mechanism which resets the casing door previously discussed from the second position back to the first position and in one embodiment simultaneously resets the swing arm to allow the primary roll of product to be replaced without necessitating a separate motion to reset the casing door and/or reset the swing arm. This is much more convenient for a janitor or other service personnel and also saves time, which could reduce costs or allow the service personnel to be engaged in more needed responsibilities. 
     The paper product dispenser in one embodiment is a dispenser for dispensing toilet paper. The dispenser utilizes a primary roll of product having an outer surface accessible to a user, and a secondary roll of product which is not accessible to a user until the primary roll is consumed. The dispenser has a frame comprising a face side; a lateral extension having a face side, a back side, and a first end, the lateral extension coupled at the first end to the face side of the frame; a primary roll support fixedly coupled to the lateral extension and extending transversely from the face side of the lateral extension, operatively configured to support the primary roll; and a secondary roll support coupled to the lateral extension, configured to support the secondary roll. In one embodiment, the secondary roll support extends transversely from the face side of the lateral extension. In one form, the swing arm extends transversely from the lateral extension and is configured to engage the outer surface of the primary roll of product which is positioned upon the primary roll support. As the primary roll is consumed, the swing arm repositions toward the center of the primary roll of product as the product disposed upon the primary roll is consumed. Once the primary roll is substantially consumed, a release latch releases. The release latch is coupled to the swing arm and is operatively configured to deny a user access to the secondary roll until the primary roll is substantially consumed. 
     In another embodiment, the secondary roll support is movably coupled to a vertical channel disposed on the lateral extension. The secondary roll support extends transversely from the face of the lateral extension so that a new roll may be installed easily. The secondary roll support includes a release latch which allows it do drop to an accessible position when the seer latch is activated. The casing of the dispenser is arranged such that the swing arm is repositioned to a reserve position as the casing is opened. The action of opening the casing may also function to reposition the secondary roll support to a reserve position, effectively resetting the dispenser automatically. This saves the time and effort of the service person replacing the product rolls. 
     In one embodiment, a casing door is provided to deny access to the secondary roll of product until the primary roll of product is substantially consumed. In this embodiment, the secondary roll support may remain in a stable position. The casing door may include a release latch, which releases the door when the primary roll of product is consumed. This would then allow a user access to the secondary roll of product. This embodiment may also include a mechanism configured such that the swing arm is operatively configured to be repositioned to a reserve position when the casing is opened. Additionally, opening the casing may also reposition the casing door to a reserve position, functionally resetting the dispenser automatically. 
     The paper product dispenser in one form includes a mechanism, such that a swing arm, that is rotatably coupled to the frame at a first end of the lower member via a lower member pivot and the lower member further comprises a channel. This channel is substantially at the second end of the lower member and is configured to slidably engage the upper member wherein the channel of the lower member directly engages the swing arm. In one form, the swing arm extends transversely from the upper member through a surface defining a channel disposed upon the lateral extension. Additionally, the swing arm may include an engagement portion operatively configured to engage the outer surface of the primary product roll until the primary product roll is substantially consumed. Once the primary roll is consumed, the seer latch is released and the secondary product roll is repositioned to a usable position. To accomplish this, in one form the swing arm further includes an engagement portion operatively configured to release the seer latch, and thus release the vertically sliding member. This operates to release the secondary roll product roll to an operational position only after the primary roll is completely consumed. 
     The paper product dispenser in another embodiment includes an upper member which is rotatably coupled to the back side of the lateral extension. This upper member includes a cam surface which slidably engages the release latch and releases the seer mechanism when the primary roll is substantially consumed. The upper member includes a cam surface and a seer point which are configured to slidably engage the seer latch while the primary product roll is not substantially consumed, and disengage from the seer latch when the primary roll is substantially consumed. To accomplish this automatic reset, the casing is rotatably attached to the frame at a casing pivot. A repositioning tab is provided, operatively configured to engage a repositioning surface on the first end of the lower member when the casing is opened to a substantially fully open position. Once the casing is opened, pressure against the repositioning surface of the lower member by the repositioning tab will rotate the lower member about the lower member pivot. This pressure will in turn rotate the upper member about the upper member pivot, operatively resetting the dispenser. Additionally, the paper product dispenser may be configured such that the lifting member is configured to exert force against a vertically sliding member, repositioning the secondary roll support to a reserve position. Thus a new secondary roll of product can be installed without additional movements. Once the rolls have been replaced, the door is re-closed and the lifting member engages the outer surface of the primary roll. 
     The paper product dispenser may also be configured such that the swing arm further includes an engagement portion operatively configured to engage the outer surface of the primary product roll until the primary product roll is substantially consumed. This engagement portion may be formed as part of the swing arm, or may be an additional structure coupled to the swing arm. Once the primary roll is consumed, the seer latch is released and a casing door is repositioned to an open position. 
     In one form, a lifting member is provided which is coupled at a first end to a lifting member pivot and extends from the lateral extension, the lifting member comprising an engagement surface substantially positioned at the second end of the lifting member which is operatively configured to slidably engage the vertically sliding member, and comprises a surface defining a channel positioned between the lifting member pivot and the engagement surface operatively configured to engage a sliding bar extending transversely from the upper member. 
     Another embodiment is disclosed wherein the seer mechanism is coupled to the casing and is operatively configured to reset from a position wherein the secondary product roll is accessible, to a position wherein the secondary product roll is inaccessible when the casing is substantially opened. Furthermore, a swing arm may be coupled to the seer mechanism, configured to engage the outer surface of the primary roll while the primary roll is being utilized. The swing arm is operatively configured to engage the seer mechanism and release the secondary roll support only when the primary roll is substantially consumed. This may be facilitated by a lower member coupled to the frame and engaging a portion of the casing. The lower member is configured to reposition the swing arm when the casing is substantially opened. 
     A paper product dispenser in one form for dispensing products is disclosed wherein the dispenser includes a swing arm coupled to the frame and configured to engage the outer surface of a primary roll of product while the primary roll is being utilized. The swing arm may be further coupled to the casing and operatively configured to reset to a first position when the casing is opened. 
     In one form a method is disclosed including the steps of first opening the casing of the dispenser. This operates the reset mechanism which is configured to automatically reset the secondary oil support and the release latch automatically. Next, the service person would remove any remaining cores on the primary roll support, and would then replace the consumed core with a substantially full roll of product; and finally, close the casing of the dispenser.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     To simplify the description and improve understanding, an axis system  10  is disclosed in  FIG. 1  and again in  FIG. 2  showing a vertical axis  12 , a lateral axis  14 , and a transverse axis  16 . The arrow indicated at  12  generally shows an upward vertical direction and the arrow at  16  generally shows a rightward direction. Of course, this axis system and the disclosed orientations are for understanding of the apparatus and should in no way be construed as limiting. 
     Looking at  FIG. 1 , there is shown one embodiment of a dispenser  20 , including a casing  22  and a latching mechanism  24 . As shown, the dispenser  20  is in the closed position and is ready for operation. The back side  26  of the casing  22  could be attached to a structure such as a wall or door. A product roll  28  is shown which in one form is a roll of toilet paper. Obviously, the dispenser  20  can be scaled to fit other rolls such as paper towels or the like. 
     Looking at  FIG. 2 , there is shown the dispenser  20  in one form with the casing  22  and product roll  28  removed. The casing  22  in one form could normally be rotatably attached to the frame  30  at the casing pivot  32 . In one form the casing pivot  32  is at the vertically lowermost extreme of the frame  30 . The product roll  28  of  FIG. 1  could be disposed upon the primary roll support  34 . As previously mentioned, a latching mechanism  24  is shown at the vertically upward portion of the frame  30 . As such latching mechanisms are known in the art, many such latching mechanisms could be made to operate as desired. A plurality of mounting holes  36  are shown which could be utilized to couple the frame  30  to a structure such as a wall or door by way of fasteners such as screws, nails and the like. 
     One embodiment of the frame  30  includes a face side  38 . Attached to the face side  38  of the frame  30  is a lateral extension  40 . The lateral extension is substantially a vertical wall-like structure having a first end  42  coupled to the face side  38  of frame  30 . The lateral extension  40  may be coupled to the face side  38  by way of frictional engagements or adhesive, or may conceivably be formed as a unitary structure. The lateral wall extension  40  provides a structure for supporting the primary roll support  34 . The primary roll support  34  may be formed as part of the lateral extension  40  or may be attached thereto by way of frictional engagements or adhesives. A plurality of gussets  44  may be provided to add rigidity to the lateral extension  40  where the primary roll support  34  couples thereto. 
     A secondary roll support  46  is also provided in one form which extends transversely from the lateral extension  40  and in one form is substantially a cylinder. The secondary roll support  46  includes an extension  48  which is coupled to a secondary roll support base  50  at a first end  52 . The secondary roll support base  50  further includes a second face  54  which frictionally and slidably engages the lateral extension  40  at a vertical channel  56 . The vertical channel  56  is comprised of a plurality of surfaces  58  and  60 , disposed within the lateral extension  40 . As shown in  FIG. 2 , the secondary roll support  46  is in a reserve position  62  wherein it is configured to support a secondary product roll  64  as shown in  FIG. 3 . Similarly, the primary roll support  34  is configured to support a primary product roll  66 . Referring back to  FIG. 2 , the second face  54  of the secondary roll support  46  engages the lateral extension  40  on a face side  68  of the lateral extension  40 . A plurality of surfaces defining a channel  70  are also disposed in the lateral extension  40  configured to allow passage and movement of a swing arm  72 . The swing arm  72  has a first end  74  substantially close to the face side  68  of lateral extension  40 , and a second end  76  substantially distant from the face  68  of lateral extension  40 . The swing arm  72  furthermore has an engagement portion  78  configured to ride on the outer surface of the primary product roll  66  as the primary product roll  66  is being used. The frame  30  may also include a recess  80  configured to accept the swing arm  72  when it is in position furthermost from the primary roll support  34 . 
     The primary roll support  34  of one embodiment may also include a channel  82  configured to receive a portion of the swing arm  72  when the swing arm  72  is in position closest to the primary roll support  34 . As will be discussed later, when a primary product roll  66  is used having a partial or split core as is known in the art, the engagement portion  78  of the swing arm  72  will ride along on the outer portion of the primary product roll  66  until the primary product roll  66  is substantially consumed at which point the engagement portion  78  will press past the end of the partial core and set substantially within or beyond the channel  82 . The end result of this operation will be discussed in detail. 
     Now looking at  FIG. 6 , a cutaway view of one embodiment of the dispenser  20  is shown including the casing  22 , and the frame  30 . As stated before, as the primary product roll  66  is consumed, the swing arm  72  will slide along channel  70  towards the primary roll support  34 . The swing arm  72  extends transversely from the upper member  84  to ride against the primary roll of product. The upper member  84  is shown in a reserve position  86 , and is coupled to the lateral extension  40  at an upper member pivot  88 . The upper member  84  further includes a cam surface  90  and a seer point  92 . These can also be seen in  FIG. 3  from a different angle. The upper member  84  in one form also includes a sliding bar  94  extending from the upper member  84 . The sliding bar  94  is coupled to the upper member  84  and engages a lifting member  96  at a channel  98  disposed within the lifting member  96 . The lifting member  96  is coupled to the lateral extension  40  at a lifting member pivot  100 . The lifting member pivot  100  is substantially at a first end  102  of the lifting member  96 . An engagement surface  104  is substantially at the second end  106  of the lifting member  96  and is configured to engage a vertically sliding member  108 . The vertically sliding member  108  is coupled through the vertical channel  56  within the lateral extension  40  to the secondary roll support  46 . The engagement surface  104  is configured to engage the vertically sliding member  108  as to reposition it. A lower member  110  is also disclosed having a first end  112  and a second end  114 . The lower member  110  is coupled to the frame  30  at a lower member pivot  116 . The lower member  110  could also be coupled to the lateral extension  40 . The lower member  110  in one form further comprises a channel  118  configured to engage the swing arm  72 . Furthermore, the lower member  110  may comprise a reset surface  120  configured to frictionally engage the reset tab  122  of the casing  22  when the casing is substantially opened as is shown in  FIGS. 14-16 . 
     Many prior art product roll dispensers require that a person attempting to restock one or more of the product rolls would first need to reset a release (seer) latch which provides access to the secondary roll of product, and then replace either the primary or the primary and the secondary roll(s) of product. In one embodiment of this disclosure as shown in  FIG. 6 , a dispenser  20  is provided wherein releasing the latching mechanism  24  (see  FIG. 1 ) and opening the casing  22  about the casing pivot  32  engages the reset tab  122  against the reset surface  120  of the lower member pivot  116  as shown in  FIG. 14 . This force upon the lower member  110  will rotate it away from the primary roll support  34  in direction of travel  140 , thus moving the swing arm  72  away from the primary roll support  34  and allowing the primary roll to be replaced without necessitating an additional movement of a user, manually repositioning the swing arm  72 . Additionally, as shown in  FIG. 15 , the dispenser  20  can be configured such that the movement of the swing arm  72  rotates the upper member  84  about the upper member pivot  88 . As the upper member  84  rotates, the sliding bar  94  exerts pressure upon the lifting member  96 , rotating it about the lifting member pivot  100 . This motion positions the engagement surface  102  against the surface  124  of the vertically sliding member  108 . As the engagement surface  104  puts pressure upon the surface  124  of the vertically sliding member  108 , it tends to reposition upwardly in direction of travel  150  along the vertical channel  56  (see  FIG. 6 ) to a reserve position. As such, if the secondary product roll  64  is substantially consumed, a user could replace it with a new unused roll. At this point the casing  22  could be closed, reengaging the latch mechanism  24  at which point the apparatus is once again ready for use. This reset mechanism would save a considerable amount of time and effort as a single motion of opening the casing  22  repositions the seer mechanism and the secondary roll support  46 . 
     Looking at  FIGS. 4 ,  7 ,  9 ,  12 ,  14 , and  15 , a progression of one embodiment is shown wherein the primary product roll  66  is consumed, the mechanisms are engaged, and upon complete consumption of the primary product roll  66 , the casing  22  is opened, resetting the apparatus of the dispenser  20 . Looking at  FIG. 4 , a primary product roll  66  is shown being a substantially new roll. Similarly, the secondary product roll  64  is in a reserve position  124  and is not available for use by a consumer. Also shown is the swing arm  72  including the engagement portion  78  which is in position to frictionally engage the outer surface  126  of the primary product roll  66 . Obviously, friction reducing agents such as Teflon, plastic, a wheel, or other mechanisms can also be employed to reduce friction between the swing arm  72  and the outer surface  126  of the primary product roll  66 . Looking at  FIG. 7 , it can be seen how the swing arm  72  moves in the direction of travel  128  as the outer surface  126   a  reduces in diameter when the primary product roll  66  is consumed. As shown, the engagement portion  78  is engaging the outer surface  126   a  of the primary roll  66  at engagement point  130 . As shown, the primary product roll  66  includes a core  132  having an outer diameter  134 . In one form, the core  132  is a partial or split core, wherein one portion of the core is supported by the primary roll support  34  and any other portions of the core extend from the transverse end  136  of the primary roll support  34  as shown in  FIG. 2 . Thus, as shown in  FIG. 9  wherein the secondary product roll  64  is still in the reserve position  124 , the swing arm  72  has traveled in the direction of travel  128  along channel  70  beyond the outer diameter  134  of the core  132 . The majority of the swing arm  72  would, not move beyond the outer diameter  134  of the core  132 ; however, the engagement portion  78  could move beyond the outer diameter  134 . 
     As the primary product roll  66  of one embodiment of the disclosure is substantially consumed, the secondary roll  64  is released, and the secondary roll support  46  slides along the vertical channel  56  from the reserve position  124  as shown in  FIG. 9  to an operational position  136  as shown in  FIG. 12 . In this position, a consumer would have access to the outer surface  138  of the secondary product roll  64  through the opening  23  as further shown in  FIG. 1 . 
     Obviously, at this stage it would be inconvenient to replace the primary product roll core  132  with a new roll even after the casing  22  were opened, as the secondary product roll  64 , the secondary roll support  46 , and the swing arm  72  could interfere with such action. Thus, an embodiment is disclosed wherein as shown in  FIG. 14 , as the casing  22  is opened about pivot point  32 , the reset tab  122  engages the reset surface  120  of the lower member  110 , which forces the lower member  110  to pivot about the lower member pivot  116  and repositions the swing arm  72  in the direction of travel as shown at  140 . In one embodiment, opening the casing  22  as described also repositions the secondary roll support  46  from an operational position  136  to a reserve position  124  in the direction indicated at  142 . 
     The specific sequence as shown in  FIG. 15 , of one embodiment of the disclosure, is that as the casing  22  rotates about the case pivot  32  in the direction as indicated at  144 , pressure is put upon the lower member  110 . The pressure exerted by the casing  22  against the lower member  110  rotates the lower member  110  about the lower member pivot  116  in the direction as indicated at  146 . This rotation and movement of the lower member  110  exerts force against the swing arm  72  by way of the channel  118 . As the swing arm  72  is connected to the upper member  84 , this force tends to rotate the upper member  84  about the upper member pivot  88  in the direction as indicated at  148 . This rotation of the upper member  84  about the upper member pivot  88  exerts force against the lifting member  96  by way of the sliding bar  94  engaging the surfaces of the channel  98 . The sliding bar  94  is coupled to the upper member  84 . This force against the lifting member  96  tends to rotate the lifting member  96  about lifting member pivot  100  in the direction as indicated at  150 . This exerts force from the lifting member  96  upon the secondary roll support  46  as previously discussed. This force tends to move the secondary roll support  46  in the direction as indicated at  152 . Thus, the two operations of the reset mechanism  154  are achieved. These operations are: repositioning the swing arm  72  such that a new roll can be placed upon the primary roll support with a minimum of effort, and also ensuring that the secondary roll support  46  is moved from an operational position  136  to a reserve position  124  as shown in  FIG. 14 . Should the secondary product roll  64  need to be replaced, that can easily be achieved at this point. 
     It is also conceived that whereas it may be beneficial to provide the primary product roll with a split or partial core, it may also be desirable to provide the secondary product roll  64  with a full-length core. 
     Now looking at  FIGS. 5 ,  8 , and  10 , it can be seen how the same sequence is achieved in views showing the reset mechanism  154  of one embodiment. Once again,  FIG. 5  shows a primary roll  66  as a substantially new roll wherein the outer surface  126  comes very close to its maximum position against the frame at the position indicated at  154 . The secondary roll support  46  is in its uppermost reserve position. The lower member  110  is shown positioned very near the frame  30  and the upper member  84  is in its position to engage the secondary support  46 . However, the seer point  92  has not passed beyond the seer latch  162 . Now moving on to  FIG. 8 , it can be seen how the outer surface  126   a  of the primary roll  66  has a substantially reduced diameter and the lower member  110  has pivoted in a direction as indicated at  156 . Thus, in turn, the upper member  84  has pivoted in the direction as shown at  158 , and the lifting member  96  has pivoted in the direction as shown at  160  wherein the engagement surface  104  of the lifting member  96  is no longer in contact with the surface  124  of the secondary roll support  46 . Moving on to  FIG. 10  the core  132  of the primary roll  66  is substantially consumed, exposing the core  132 , and the lower member  110  has rotated in direction  156   a  to its furthest position. Thus, the upper member  84  has rotated to its furthermost position as indicated in direction  158  and the lifting member  96  has rotated to its furthest position as indicated in direction  160   a . Looking closely at the point where the upper member  84  comes in contact with the secondary roll support  46 , it can be seen that the seer latch  162  is still in contact with the cam surface  90  of the upper member  84 . In one embodiment, as the upper member  84  rotates such that the cam surface  90  is no longer in contact with the seer latch  162 , to be more specific the seer point  92  has passed beyond the edge of the seer latch  162 , it can be seen how the secondary roll support  46  will then drop down, exposing the secondary product roll  64  through the opening  23  to an operational position. 
     This particular embodiment of a seer mechanism can further be seen in  FIGS. 11 and 13 , wherein at  FIG. 11  the primary roll is not completely consumed and the secondary roll is still in its reserve position. In  FIG. 13  however, the seer latch  162  is no longer in contact with the cam surface  90 , and the upper member  84  is rotated such that the seer point  92  has passed beyond the seer latch  162  and the secondary roll support  46  has dropped along the vertical channel  56  from the reserve position  124  to the operational position  136 . 
     Now looking at  FIG. 16 , the reset series as previously discussed is shown from the left transverse side, showing once again the reset mechanism  154 . As has been previously discussed, as the casing  22  is rotated to an open position, forces are exerted upon the lower member and other associated portions of the reset mechanism  154  to reposition the swing arm  72  to a position furthest from the primary roll support  34 , and in one embodiment, substantially simultaneously reposition the secondary roll support  46  from the operational position  136  to the reserve position  124 . 
     Now looking at  FIG. 3   a , a detailed view of the release system  164  in one form can be seen. As previously discussed, the vertical sliding member  108  rides substantially within the vertical channel  56 , which allows it to move vertically but hinders any rotation or lateral or transverse motion. The seer latch  162  in this embodiment is comprised as a portion of the vertically sliding member  108 . As can be seen, the seer latch  162  comprises a first end  164  and a second end  166 . Furthermore, the seer latch  162  comprises a back side or surface  168  and generally consists of a spring portion  170 . The second end  166  of the spring portion  170  rides along the cam surface  90  of the upper member  84 . As the primary product roll is consumed, the upper member  84  is caused to rotate about the upper member pivot  88  in the direction indicated at the arrow  158 . As can be seen, the radius  172  between the center of the upper member pivot  88  and the cam surface  90  allows the second end  166  to ride along the cam surface  90  with no substantial movement of the vertical sliding member  108 . Once, however, the upper member  84  rotates such that the second end  166  of the seer latch  162  passes the seer point  92 , the entire secondary roll support  46  is released downward from the reserve position to an operational position. 
     In this embodiment, one advantage of the spring portion  170  is that as the casing is opened, resetting the device as previously discussed, the upper member  84  tends to rotate prior to repositioning the vertically sliding member  108 . Thus, as the vertically sliding member  108  is repositioned upwardly along the vertical channel  56 , the spring portion  170  deforms and the back surface  168  rides against the transverse inward edge  174  of the cam surface  90 . Once the second end  166  passes vertically beyond the cam surface  90 , the spring portion  170  reforms to its original orientation and as the vertically sliding member is released. The second end  166  once again engages the cam surface  90  and the process begins again. 
     Looking at  FIG. 17  is shown another embodiment of a dispenser  420 , including a casing  422  and a latching mechanism  424 . As shown, the dispenser  420  is in the closed position and is ready for operation. The back side  426  of the casing  422  could be attached to a structure such as a wall or door. A casing door  600  is provided, partially covering an opening  423  in the casing which controls access to a secondary roll of product. A product roll  428  is shown which in one form is a roll of toilet paper. Obviously, the dispenser  420  can be scaled to fit other rolls such as paper towels or the like. 
     Looking at  FIG. 18 , there is shown the dispenser  420  in one form with the casing  422  and product roll  428  removed. The casing in one form could normally be rotatably attached to the frame  430  at the casing pivot  432 . In one form the casing pivot  432  is at the vertically lowermost extreme of the frame  430 . The product roll  428  could be disposed upon the primary roll support  434 . As previously mentioned, a latching mechanism  424  is shown (in  FIG. 17 ) at the vertically upward portion of the frame  430 . The latching mechanism  424  engages the surfaces defining openings  425  near the topmost portion of the frame  430 . As such latching mechanisms are known in the art, many such latching mechanisms could be made to operate as desired. A plurality of mounting holes  436  are shown in  FIG. 18  which could be utilized to couple the frame  430  to a structure such as a wall or door by way of fasteners such as screws, nails and the like. 
     One embodiment of the frame  430  includes a face side  438 . Attached to the face side  438  of frame  430  is a lateral extension  440 . The lateral extension is substantially a vertical wall-like structure having a first end  442  coupled to the face side  438  of frame  430 . In the embodiment shown in  FIG. 18 , the lateral extension  440  is attached via a box-like portion  443 . The lateral extension  440  may be coupled to the face side  438  by way of frictional engagements, adhesive, or may conceivably be formed as a unitary structure. The lateral wall extension  440  provides a structure for supporting the primary roll support  434 , the secondary roll support  446 , and other elements. The primary roll support  434  may be formed as part of the lateral extension  440  or may be attached thereto by way of frictional engagements or adhesives. 
     A secondary roll support  446  is also provided which extends transversely from the lateral extension  440  and in one form is substantially a cylinder. The secondary roll support  446  includes an extension  448  which is coupled to a secondary roll support base  450 . The secondary roll support  446  is configured to support a secondary product roll  464  as shown in  FIG. 20 . Similarly, the primary roll support  434  is configured to support a primary product roll  466 . Referring back to  FIG. 18 , a plurality of surfaces  469  defining a channel  470  may be disposed in the lateral extension  440  configured to allow passage and movement of a swing arm  472 . Referring to  FIG. 5 , as the swing arm  472  is attached to the upper member  484 , which exhibits about an upper member pivot  488 , it may be convenient to have these surfaces  469  form and arc centered about the center of the upper member pivot  488 . Looking again at  FIG. 2 , the swing arm  472  having a first end  474  near the face side  468  of lateral extension  440 , and a second end  476  substantially distant from the face side  468  of lateral extension  440 . The swing arm  472  furthermore has an engagement portion  478  configured to ride on the outer surface of the primary product roll  466  as the primary product roll  466  is being used. The frame  430  may also include a recess  480  disposed within the face side  438  configured to accept a portion of the swing arm  472  when it is in position furthermost from the primary roll support  434 . 
     The primary roll support  434  of one embodiment may also include a channel  82  as shown in  FIG. 2  configured to receive a portion of the swing arm  472  when the swing arm  472  is in position closest to the primary roll support  434 . As will be discussed later, when a primary product roll  466  (see  FIG. 20 ) is used having a partial or split core as is known in the art, the engagement portion  478  of the swing arm  472  will ride along on the outer portion of the primary product roll  466  until the primary product roll  466  is substantially consumed, at which point the engagement portion  478  will press past the end of the partial core and set substantially within the channel. The end result of this operation will be discussed in detail. 
     Now looking at  FIG. 21 , a hidden line view of one embodiment of the dispenser  420  in one form is shown including the casing  422  and the frame  430 , As stated before, as the primary product roll is consumed, the swing arm  472  will slide along channel  470  towards the primary roll support  434 . The swing arm  472  extends from the upper member  484 . The upper member  484  is shown in a reserve position  486 , and is coupled to the lateral extension  440  at an upper member pivot  488 . The upper member  484  further includes a cam surface  490  and a seer point  492 . These can also be seen in  FIG. 19  from a different angle. A lower member  510  is also shown in  FIG. 21  having a first end  512  and a second end  514 . The lower member  510  is coupled to the frame  430  at a lower member pivot  516 . The lower member  510  could also be coupled to the lateral extension  440 . The lower member  510  further comprises a plurality of surfaces forming a channel  518  configured to engage the swing arm  472 . Furthermore, the lower member  510  comprises a reset surface  520  configured to frictionally engage a reset tab  522  when the casing is substantially opened as is shown in  FIGS. 31 and 33 . 
     Many prior art product roll dispensers require that a person attempting to restock one or more of the product rolls would first need to reset a release (seer) latch which controls access to a secondary roll of product, reset the mechanism which releases the secondary roll, and then replace either the primary and/or the secondary rolls of product. In one embodiment of this disclosure, a dispenser  420  is provided as shown in  FIG. 31  wherein releasing a latching mechanism and opening the casing  422  about the casing pivot  432  engages the reset tab  522  against the reset surface  520  of the lower member  510 . This pressure tends to rotate the lower member  510  away from the primary roll support  434  in the direction indicated at  506 . The motion of the lower member  510  repositions the swing arm  472  away from the primary roll support  434 , allowing the primary roll to be replaced without necessitating an additional movement of a user manually repositioning the swing arm  472 . Additionally, the dispenser  420  can be configured such that a lifting member  496  engages the outer surface  526  of the primary product roll  466  as in  FIG. 36  which tends to rotate a casing door  600  from an open position  536  as shown in  FIG. 28 , to a reserve position  524  as shown in  FIG. 36 . Looking at  FIG. 22 , it can be seen how the lifting member  496  may extend from the right and/or the left transverse portion of the casing door  600 . The casing pivots  602  can also be seen clearly and are furthermore shown in  FIG. 23  rotatably coupled to the casing  422 . A casing door pivot  602  is provided which rotationally couples the casing door  600  to the lateral extension  440 . As such, if the secondary product roll  464  and/or primary product roll  466  is substantially consumed, a user could replace it with a new unused roll. At this point the casing  422  could be closed, reengaging the latching mechanism at which point the apparatus is once again ready for use. This reset mechanism would save a considerable amount of time and effort as the motion of opening and re-closing the casing  422  repositions the seer mechanism and the casing door  600  to a reserve position  524 . 
     Looking at  FIGS. 20 ,  24 ,  26 ,  28 ,  30 ,  32 ,  34 , and  36 , a progression of one embodiment is shown beginning with  FIG. 20 , wherein the primary product roll is consumed, the mechanisms are engaged, and upon complete consumption of the primary product roll, the casing door is opened providing access to a secondary product roll  464 , the consumed product rolls are replaced, and the casing is re-closed. These actions reset the apparatus of the dispenser  420 . Looking at  FIG. 20 , a primary product roll  466  is shown being a substantially new roll. The casing door  600  is closed and thus, the secondary product roll  466  is not available for use by a consumer. This can be seen by looking at  FIG. 1 , and at  FIG. 4  where the casing door  600  is in the closed or reserve position  524  and the lip  601  of the casing  422  overlaps the recess  603  of the casing door  602 . Also shown is the swing arm  472  including the engagement portion  478  which is in position to frictionally engage the outer surface  526  of the primary product roll  466 . Obviously, friction reducing agents such as Teflon, plastic, a wheel, or other mechanism can also be employed to reduce friction between the swing arm  472  and the outer surface  526  of the primary product roll  466 . A plurality of tabs  473   a  and  473   b  may also be utilized to maintain the swing arm  472  upon the plurality of surfaces  469   a  and  469   b  to maintain their position upon the channel  470 . 
     Looking at  FIG. 24 , it can be seen how the swing arm  472  moves in the direction of travel  528  as the outer surface  526   a  reduces in diameter when the primary product roll  466  is consumed. As shown, the engagement portion  478  is engaging the outer surface  526   a  at point  530 . As shown, the primary product roll  466  includes a core  532  having an outer diameter  534 . In one form, the core  532  is a partial or split core wherein one portion of the core is supported by the primary roll support  434  and any other portions of the core extend from the transverse end  537  of the primary roll support  434  as shown in  FIG. 18 . Thus, as shown in  FIG. 26  wherein the casing door  600  is still in the reserve position  524 , the swing arm  472  has traveled in the direction of travel  528  along channel  470  beyond the outer diameter  534  of the core  532 . The majority of the swing arm  472  would, of course, not extend beyond the outer diameter  534  of the core  532 , however, the engagement portion  478  would extend beyond the outer diameter  534 . 
     As the primary product roll  466  s substantially consumed, the casing door  600  of one embodiment of the disclosure is released as shown in  FIG. 28 , and from the reserve position  524  as shown in  FIG. 26  to the open position  536  as shown in  FIG. 28 . In this position, a consumer would have access to the outer surface  538  of the secondary product roll  464  through the opening  423 . 
     At this stage it would be inconvenient to replace the primary product roll with a new roll as the swing arm  472  could interfere with such action. Thus, an embodiment is disclosed wherein as shown in  FIG. 31 , as the casing  422  is opened about pivot point  432  in direction of travel  544 , the reset tab  522  engages the reset surface  520  of the lower member  510 , which forces the lower member  510  to pivot about the lower member pivot  516  in direction of travel  545  and repositions the swing arm  472  in the direction of travel as shown at  540 . This provides sufficient space between the primary roll support  434  and the swing arm  472  to replace the consumed core with a new primary roll of product. 
     Now looking at the embodiment shown in  FIG. 30 , the latching mechanism has been released, and the casing  422  has been partially opened, and rotated about casing pivot  432 . 
       FIG. 31  shows the dispenser  420  in the same position as  FIG. 30 , but from the right side. In both of these views, it can be seen is how the lifting member  496  has moved a short distance away from the primary roll support  434  as the casing  422  is opened. As the casing  422  continues to rotate to a more open position, the casing door pivot  602  will thus be caused to move further from the casing frame  430 . Looking at  FIG. 30 , it can be seen how as the casing door  600  is allowed to freely pivot about the casing door pivot  602 . The center of gravity  605  of the casing door  600  will tend to remain vertically below the casing pivot  602  as the casing  422  is opened and closed. As the casing  422  is opened about casing pivot  432 , and the casing pivot  602  moves laterally away from the frame  430 , the center of gravity  605  of the casing door  600  will remain in a line  607  which is substantially vertically below the casing pivot  602 . Thus the lifting member  496  will tend to be repositioned away from the primary roll support  434 . This allows for a primary roll of product to be positioned on the primary roll support  434  without the additional effort of moving the casing door  600  nor the lifting member  496 . 
     As shown in  FIG. 34 , the dispenser  420  in one form can be configured such that a lifting member  496  engages the outer surface  526  of the primary product roll  466  which tends to rotate the casing door  600  from an open position  536  as shown in  FIG. 28  towards a reserve position  524  as further shown in  FIG. 36 . Referring back to  FIG. 34 , casing door pivot  602  is provided which rotationally couples the casing door  600  to the lateral extension  440 . At this point, the casing  422  could be closed, reengaging the latching mechanism at which point the apparatus is once again ready for use. Thus, the motion of opening and re-closing the casing  422  repositions the seer mechanism, and the casing door  600  to a reserve position  524  as shown in  FIG. 36 . 
     The specific sequence as shown in  FIG. 31 , of one embodiment of the disclosure, is that as the casing  422  rotates about case pivot  432  in the direction as indicated at  544 , pressure is put upon the lower member  510 . The pressure exerted by the casing  422  against the lower member  510  rotates the lower member  510  about lower member pivot  516  in the direction as indicated at  545 . This rotation of the lower member  510  exerts force against the swing arm  472  along the channel  418  in the direction of travel  540 . As the swing arm  472  in one form is connected to the upper member  484 , this force tends to rotate the upper member  484  about the upper member pivot  488  in the direction as indicated at  548 . A new primary roll  466  is then positioned upon the primary roll support  434  as shown in  FIG. 32 . As the casing  422  is re-closed, the lifting member  496  engages the outer surface  526  of the primary roll  466  as shown in  FIG. 34 . This repositions the casing door  600  to the reserve position  524  of  FIG. 36  wherein the secondary product roll  464  is no longer accessible. Looking at  FIG. 37 , it can be seen how as the casing  422  is re-closed, the seer latch  562  moves past the upper member  484  without engaging the seer point  492 , nor the cam surface  490 . As shown, the casing door  600  is substantially closed. As the new primary roll is consumed, the lifting member  496  continues to ride on the outer surface  526  of the primary roll  466  as shown in  FIG. 36 , until the seer latch  562  once again engages the cam surface  490  as shown in  FIG. 21 . At this point the primary roll  466  no longer engages the lifting member  496 , and the secondary product roll  466  is still not available for use (see  FIG. 20 ) until the primary roll  466  is substantially consumed. Thus, the two operations of the reset mechanism are achieved. These operations are: repositioning the swing arm  472  such that a new roll can be placed upon the primary roll support  434  with a minimum of effort and also the casing door  600  is moved from an operational position  536  as shown in  FIG. 28  to a reserve position  524  as shown in  FIG. 20 . Should the secondary product roll need to be replaced at the same time, that can easily be achieved. 
     It is also conceived that whereas it may be beneficial to provide the primary product roll with a split or partial core, it may also be desirable to provide the secondary product roll  464  with a full-length core. 
     This particular embodiment of a seer mechanism can further be seen in  FIGS. 27 and 29 , wherein at  FIG. 27  the primary roll is not completely consumed and the casing door  600  is still in its reserve position  524 . In  FIG. 29  however, the seer latch  562  is no longer in contact with the cam surface  490  and the upper member  484  is rotated in direction of travel  549  such that the seer point  492  has passed beyond the seer latch  562  and has dropped along the channel  456  causing the casing door  600  to pivot from the reserve position  524  of  FIG. 27  to the operational position  536  of  FIG. 29 . 
     Now looking at  FIG. 33 , the reset mechanism  554  as previously discussed is shown from the right transverse side. As has been previously discussed, the casing  422  is rotated to an open position, forces are exerted upon the lower member  510  and other associated portions of the reset mechanism  554  to reposition the swing arm  472  to a position furthest from the primary roll support  434  and functionally reset the apparatus. In this form, a primary roll of product is easily positioned upon the primary roll support  434 . And a secondary roll of product is easily positioned upon the secondary roll support  446 . 
     Looking at  FIG. 38 , an embodiment of the dispenser  620  is disclosed comprising a swing arm  673  which is considerably longer than previously disclosed embodiments. A secondary roll support  446  is also provided which extends transversely from the lateral extension  440  and in one form is substantially a cylinder. The secondary roll support  446  includes an extension  448  which is coupled to a secondary roll support base  450 . The secondary roll support  446  is configured to support a secondary roll of product. Similarly, the primary roll support  434  is configured to support a primary roll of product. A plurality of surfaces defining a channel  470  are also disposed in the lateral extension  440  configured to allow passage and movement of a swing arm  673 . The swing arm  673  has a first end  674  near the face side  468  of the lateral extension  440 , and a second end  676  substantially distant from the face  468  of lateral extension  440 . The swing arm  673  furthermore has an engagement portion  678  configured to ride on the outer surface of the primary product roll as the primary product roll  466  is consumed. The frame  430  may also include a recess  480  upon the face side  438  configured to accept a portion of the swing arm  673  when it is in position furthermost from the primary roll support  434 . 
     The primary roll support  434  of one embodiment may also include a channel (not shown) configured to receive a portion of the swing arm  673  when the swing arm  673  is in position closest to the primary roll support  434 . As will be discussed later, when a primary product roll is used having a partial or split core as is known in the art, the engagement portion  678  of the swing arm  673  will ride along on the outer portion of the primary product roll until the primary product roll is substantially consumed at which point the engagement portion  478  will press past the end  536  of the primary roll support. The end result of this operation will be discussed in detail. 
     The swing arm  673  as shown is substantially longer than the primary roll support  434 . Furthermore, the swing arm  673  includes a reset extension  624  which extends transversely beyond the end  536  of the primary roll support  434 . Furthermore, the reset extension  644  includes an outer surface  627  adapted to engage the outer surface of the primary roll of product as will be discussed in detail. The user exerting force upon the reset extension  624  functions to reposition the swing arm  673  away from the primary roll support  434  to position a primary roll of product thereupon. 
     Looking at  FIG. 39 , it can be seen how force exerted upon the swing arm  673  away from the primary roll support  434  will cause the upper member  484  to rotate about the upper member pivot  488  in the direction as indicated at  548 . This will rotate the cam surface  490 , and the adjacent seer point  492  to a position to engage the seer latch  562  when the casing is re-closed, as has been previously discussed. Looking at  FIG. 40  it can be seen how as the primary roll of product is consumed, the swing arm  673  will ride upon the outer surface of the primary roll of product, and reposition the swing arm  473  in the direction as indicated at  528  towards the primary roll support  434 .  FIG. 41  shows the upper member  484  repositioned closer to the primary roll support  434  as shown in  FIG. 40 .  FIG. 42  shows the last moment in which the seer latch  562  is engaged by the cam surface  490 , and any further rotation of the upper member  484  towards the primary roll support  434  will result in the seer point  492  passing beyond the seer latch  562  releasing it to an operational position  536  as shown in  FIG. 43 . 
     As shown in  FIG. 44 , the casing  422  has been opened about casing pivot  432  which provides for replacement of a primary roll of product  466  upon the primary roll support  434 , and a secondary roll of product  464  upon the secondary roll support  446 . As shown in  FIG. 45 , the secondary roll of product  464  is positioned upon the secondary roll support  446  and the primary roll of product  466  is positioned beyond the end  536  (see  FIG. 38 ) of the primary rolled support  434 . Thus the outer surface  526  has engaged the outer surface  627  of the reset extension  624  and is thus repositioning the swing arm  673  in the direction as indicated at  540 . Looking at  FIG. 48 , it can be seen how as the swing arm  673  (which is attached to the upper member  484 ) is repositioned in the direction indicated at  540 , the upper member  484  rotates about the upper member pivot  488 .  FIG. 46 , which is taken along line  46  of  FIG. 45 , shows a cut away end view of the dispenser  620  and shows in much better detail how the primary roll of product is positioned past the end  536  of the primary roll support  434 . This figure further shows how the outer surface  526  of the primary roll of product  466  engages the outer surface  627  of the swing arm  673 . Once the primary roll of product  466  has sufficiently repositioned the swing arm  673 , the core of the primary roll of product  466  can be positioned upon the outer surface of the primary roll support  434 . It can then be repositioned transversely along the outer surface  627  of the swing arm  673  into its final position. In its final position, the engagement portion  678  will ride upon the outer surface  526  of the primary roll of product  466 . The engagement portion  678  may comprise friction reducing elements as previously discussed and may further comprise a flat spot or a recess  679 . As the primary roll of product  466  is positioned transversely upon the outer surface of the primary roll support  434 , the recess  679  ensures that the engagement portion  678  will not “catch” on the primary roll of product  466 . 
     Once the above mentioned steps have been accomplished, as shown in  FIG. 47 , the casing  620  may be re-closed as shown in  FIG. 49  functionally resetting the dispenser  620 . As previously discussed, the lifting member  496  will engage the outer surface  526  of the primary roll of product  466 , closing the casing door  600 . 
     At this stage it would be inconvenient to replace the primary product roll  466  with a new roll, as both the secondary product roll  464  and the swing arm  673  could interfere with such action. Thus, an embodiment is disclosed wherein as shown in  FIG. 44-50 , as the casing  422  is opened about pivot point  432  a new primary roll  466  is positioned past the primary roll support  434 , such that the outer surface  526  of the primary roll  466  presses upon the outer surface  627  of the reset extension  624  of the swing arm  673 . The pressure exerted by the outer surface  526  of the primary roll  466  rotates the lower number  510  about lower member pivot  516  in the direction as indicated at  540 . Once the swing arm  673  has been repositioned a substantial distance from the primary roll support  434 , the primary roll  466  can be positioned upon the primary roll support  434 . Thus it is provided that the swing arm  673  can be repositioned and the primary roll  466  replaced very easily and quickly may be accomplished using only one hand. 
     The individual elements of this disclosure may be formed of machined or molded polymer, metals, resins, similar materials, or a combination thereof.
