PAPER ROLL HOLDING AND DISPENSING DEVICE This invention relates to a holder and dispenser device for toilet paper and the like, and more particularly to a device for securely journaling toilet paper rolls or the like for ready removal of the paper as needed in a manner that substantially fully covers the roll.
Conventional toilet paper mounting arrangements the fixture so that the toilet paper is recessed mounted within the wall.
In any event, the roll of paper is ordinarily fully exposed to view and dust accumulations, and notinfrequently is either too readily displaced from its mounted position, or difficult to remove from the fixture due to the tendency of the retractable spindle to resist contraction and removal.
A principal object of this invention is to provide a toilet paper holder and dispensing device in which the roll is firmly journaled in placeand remains fully enclosed or masked while in use, and on opening up the device to replace the roll, the remaining roll core is readily removed and replaced by a new roll, which, on reclosing the device, again securely journals the roll for use in a masked condition.
Another object of the invention is to provide a toilet paper holder arrangement in which a pair of opposed core journaling assemblies provide a two stage roll core journaling action, whereby the roll core is securely journaled for use, and when the roll is to be replaced, the core journaling is reduced in securement to a snap fitting relation whereby the used roll core can be readily snapped free of the holder and the new roll just as readily snapped into place.
Still other objects of the invention are to provide a toilet paper holder and dispenser arrangement that is economical of manufacture, convenient to apply and use, and long-lived in operation.
In accordance with this invention, a toilet paper roll holder and dispenser is provided comprising a journaling arrangement for the roll having a two stage journaling function, in combination with a retractable cover that normally covers or masks the toilet paper when in use, with the parts being arranged such that when the cover masks the toilet paper, the roll is firmly journaled against displacement by a pair of opposed journaling assemblies that retract to an initial paper core mounting position, on the cover being moved to open position to replace the toilet paper, which then permits the empty roll to be readily snapped free from the journaling assemblies and a new roll readily snapped back into place with respect to the journaling assemblies. Return of the cover to its masking position over the roll extends the journaling assemblies into the core roll for secure journal mounting of the roll within the holder.
One embodiment of the invention is directed to new holder installations while another embodiment of the invention is directed to adapting existing holders to provide the advantages of this'invention.

GENERAL DESCRIPTION Reference numeral 10 of FIGS. 1 and 2 generally indicates one embodiment of the invention applied to a wall 12 of a water closet or the like for the purpose of mounting a toilet paper roll 14 (see FIG. 3) where needed. The roll of paper 14 illustrated is intended to represent any commercially available toilet paper available in roll form and comprises the usual paper ribbon l5 wound up as at 16 on a suitable tubular core 18. Core 18 usually takes the form of a tube formed from paperboard or the like and defining a bore 20 through which extends the usual spindle that mounts the roll 14 in connection with conventional toilet paper holders and dispensers.
The device 10, in accordance with this invention, comprises a pair of opposed roll retainer journaling assemblies 22 and 24 (see FIG. 3), between which the roll 14 is journaled, and which are in turn mounted in the respective arms 26 and 28 of an open centered frame 30 through which operates a pivotally mounted masking cover 32. Cover 32 has fixed to its outer marginal edge portion 34 a U shaped handle 36 that is suitably fixed to cover 32 and that includes arms 38 and 40 on either side of the cover each of which has fixed to the respective projecting ends thereof the respective receptacles 42 and 44 which are journaled in the recesses 46 and 48 of the respective arms 26 and 28 that are shaped to substantially complement the exterior surfaces 50 and 52, respectively, of the respective receptacles 42 and 44.
The journaling assemblies 22 and 24 are similar. The journaling assembly 22 in addition to the receptacle 42 comprises a casing 56 received in the receptacle 42 and containing a spring biased head 58 including a rounded protuberance 60. The journaling assembly 24 in addition to the receptacle 44 comprises casing 62 mounting a spring biased head 64 including a rounded protuberance 66.
The journaling assemblies 22 and 24 are operably associated with cover 32 such that when the cover 32 is moved counterclockwise of FIGS. 1 and 2 to expose the roll 14, casings 56 and 62 retract from the extended positions of FIG. 3 to the contracted position illustrated by FIG. 4. Opening of the cover 32 in this manner gives access to the space 70 from the front side 72 of the frame 30, and when the cover 34 and handle 36 are in the dashed line position of FIG. 2 the roll may then be inserted in the space 70 and snapped between heads 58 and 64, with the protuberances of the respective heads substantially centered in the bore 20 of core 18.
As indicated in FIGS. 2 and 3, the rear side 74 of the frame 30 is equipped with a back wall structure 76, the inside of which complements the configuration of the cover 32 and receives same when the cover is in its open position. Wall structure 76 projects through the open center 78 of frame 30, as at 80, and mounts one or more rollers 82, which cooperate with corresponding roller 84 carried by the handle 36, in training the paper ribbon through the restricted opening 88 that is provided between the cover 32 and portion 80 of wall structure 76 in the closed position of the cover.
Once the roll 14 is seated on the heads 58 and 64, the sheet of toilet paper is pulled down off the roll 14 sufficiently to overlie the wall structure roller 82 several inches, after which the cover 32 and its handle 36 are returned to the position of FIGS. 1 and 2, which has the effect of extending the casings 56 and 62 into the bore of the roll core 18 to firmly journal the roll 14 for use.
The handle 36 is notched as at 90 and on either side of the notch 90 the handle is formed with cutting edges 92 and 94 to facilitate separating a length of the toilet paper from the roll. After such separation, the notch 90 provides a finger gripping recess for gripping the severed edge of the paper to pull it downwardly of rollers 82 and 84 for obtaining another length of the paper.
The embodiment 10A of FIGS. 8 13 is adapted for application to existing conventional toilet paper holder fixtures, one familiar form of which is indicated at and comprises a frame 102 having an open center 104 and defining a pair of forwardly projecting arms 106 and 108. Curved rear wall structure 110 closes off the rear side of frame 102 to define a space 112 in which the toilet paper is mounted on a resiliently contractible spindle journaled between the arms 106 and 108. Arms 106 and 108 are conventionally socketed as at 114 to receive the ends of the said conventional spindle (which is not shown).
The device 10A comprises a pair of side members and 122 that snap into interfitting relation along the sides of frame 102 and are equipped with the respective bosses 124 and 126 that seat in the respective recesses 114 in arms 106 and 108, respectively.
Cover 32A is journaled between the side members 120 and 122 for swinging movement between the open position shown in FIG. 7 and a closed position overlying the space 112 to operably mount the roll 14 (not shown in FIGS. 7 13) in operation position for rotation about an axis 129 (see FIG. 13) that is in substantial alignment with recesses 114 of frame arms 106 and 108.
Cover member 32A is equipped with a pair of journaling assemblies 22A and 24A on either side of same that are respectively adapted to cooperate with the respective side pieces 120 and 122 to provide the two phase roll mounting or journaling action described in connection with the device 10.
Thus, the journaling assembly 22A comprises a generally rounded casing 130 mounted in the cover 32A for reciprocating movement in opposition to the assembly 24A and is spring biased to the relative position indicated in FIGS. 9 and 10 with respect to the cover 32A. Casing 130 includes a spring biased head 132 provided with a rounded or spherically contoured protuberance 134. The casing 130 is formed with a cam surface 136 positioned to engage side member 120 as the cover 32A is sw'ung to its closed position to move the casing 130 from the position of FIGS. 9 and 10 to.
the position of FIG. 12 in which the casing 130 is extended toward its opposing casing 130A for insertion into the core 18 of the toilet paper.
Journaling assembly 24A is arranged in an identical manner, except that the cam surface (not shown) of its casing 130A is oppositely curved for cooperation with the side piece 122 in a manner similar to that described in connection with the casing 130 but in the opposite direction.
The cover 32A is equipped with spaced rollers 140 adapted to cooperate with spaced rollers 142 carried by the side members 120 and 122 to train the toilet paper through a restricted opening 144 that is formed between the cover 32A and frame 102 when the cover 32A is swung to its closed position. Cover 32A is formed with cutting edges 146 and 148 on either side of a notched paper access gripping portion 150 of the cover that serves the same purposes as the corresponding parts of the device 10.
When the cover 32A is in its position of FIG. 7, the roll 14 may be snapped between the journaling assembly heads 134 to lodge them in the bore 20 of the roll core 18, and the paper ribbon 15 is trained through opening 144. The cover is then swung upwardly to bring the casings 130 into camming engagement with the side pieces 120 and 122, respectively, in the manner already indicated, to then extend the casings into the roll core. This same action brings rollers 140 against the paper ribbon to press it against rollers 142, as indicated in FIG. 8. The spring biasing action of the casings 130 against side pieces 120 and 122 holds the cover 32A in closed position, although if desired the side pieces 120 and 122 may be formed with shallow indentations in which the casings 130 are to lodge to provide a simple type of latching device for maintaining the cover 32A in its closed position.
SPECIFIC DESCRIPTION Returning to device 10, the frame 30, cover 32, and wall structure 76 may be formed from any suitable plastic or metallic materials having the general shapes indicated.
The frame 30 is preferably quadrilateral in configuration defining top and bottom portions 160 and 162 and side portions 164 and 166 integrally joined at the corners 165 of the frame. Wall structure 76 comprises a curved rear wall 168 that curves in a concentric manner about the axis 170 of pivotal movement of the cover 32 and its handle 36. Wall structure 76 also includes planar sides 172 and 174, with the sides 172 and 174 and curved wall 168 being a one piece structure in the form illustrated, and suitably fixed to the frame 30 in the position indicated, with portion 80 thereof extending forwardly of the frame through its open center portion 78. This securement may be by way of suitable adhesives, or welding, or the like, depending on the materials from which these parts are formed.
The frame arms 26 and 28 are suitably formed to define the generally cylindrical recesses 46 and 48, respectively, that receive the respective receptacles 42 and 44. r i
The cover 32 is in the form of a curved wall 180 that is arced to be concentric with the axis 170 and also telescope within wall structure 76. Cover 32 also includes planar side walls 182 and 184 which are suitably notched as at 186 and 188, respectively to accommodate the respective journaling assemblies 22 and 24."
The handle 36 is of generally U shaped configuration comprising cross member 190 and side members 38 and 40. The cross member 190 in the form shown is provided with suitable brackets 192 between which the rollers 84 are journaled. While the one roller 84 is shown, the rollers 84, like rollers 82, may be in spaced opposed pairs in the manner suggested in FIG. 7 with regard to rollers 140 and 142.
The cover 32 is suitably fixed to handle 36 along its side members 38 and 40, by employing a suitable adhesive, soldering or the like, depending upon the materials from which these parts are formed. In the form shown, the cross piece 190 of handle 36 includes a flange 194 that is also suitably affixed to the cover wall 180 to close off access to the space 70 at this point.
The casing 42 of journaling assembly 22 is of cylindrical cupped shaped configuration comprising an annular rim 200 and a substantially planar end wall 202 suitably joined together to define the operating recess 203 formed by receptacle 42. Receptacle 42 is open ended as'at 204 to receive the casing 56. As indicated in FIG. 5, the rim or side wall 200 of receptacle 42 is formed with a helically contoured slot 206 into which extends lug 208 of the casing 56. Lug 208 also operates in rectilinear slot 210 of the arm 26 (see FIGS. 3 and 4), which slot 210 extends parallel to the axis 170. As the handle arm 38 is fixed to the receptacle 42, when the handle 36 is moved from the full line position to the broken line position of FIG. 2, the receptacle 42 moves with it and the action of helical slot 206 on the casing lug 208 moves the casing 56 from the position of FIG. 3 to the position of FIG. 4. Movement of the handle 36 back to the full line position of FIG. 2 returns the casing 56 to the position of FIG. 3. Slots 206 and 210 and lug 208 thus form cam and cam follower means for moving the casing 56 rectilinearly in a reciprocating manner.
The casing 56 defines an end wall 210 and an annular rim or side wall 212 that are integrally united to define the cupped shaped configuration that is indicated, which is open ended as at 214 to receive the head 58. Head 58 generally comprises a body 216 shaped to define the spherically contoured protuberance 60 in hemispherical form which has a flange 218 in circumambient relation thereabout. Rim 212 of the casing 56 is formed with a turned over edge portion 220 against which the flange 218 seats to serve as a stop limiting movement of the head 50 outwardly of the casing 57. Edge portion 220 has an outer curved annular surface 221 that cams the roll core ends into centered relation with casing 56 when the casing 56 is extending into the roll core bore 20. The outer surface 223 of casing 56 is cylindrical and is proportioned for a loose friction fit within the roll core bore. Lug 208 is integral with casing 56.
The head 58 includes a suitable number of centering nibs 222 about its periphery that are in sliding engagement with the rim 212 of the casing 56.
The head 58 on opposite sides of its flange 218 is equipped with lugs 230 that ride in guide slots 232 formed in the rim or side wall 212 of the casing 56. A suitable compression spring 234 is interposed between the casing wall 210 and head 58 to spring bias the head outwardly of the casing.
The journaling assembly 24 is arranged in the same manner as journal assembly 22 except that the helically contoured slot 206A of the receptacle 44 is oppositely threaded and on the opposite side of receptacle 44 so that casing 62 moves oppositely of casing 56. Corresponding parts of operating assembly 24 where shown have been given the same reference numerals as employed in connection with the same parts of operating assembly 22, and those parts of the receptacle 44, the casing 62, and head 64 that are not shown are the same as the corresponding parts of journaling assembly 22. The lug 208 of casing 62 operates in rectilinear slot 210A formed in the frame arm 28.
Casings 56 and 62 and heads 58 and 64 may be formed of suitable plastic or metallic substance.
Rollers 82 of the wall structure 76 are suitably journaled on suitable mounting plates 240 suitably affixed to the wall 168.
Frame 30 and the parts it carries may be fixed to wall 12 in any suitable manner, as by applying suitable screws through wall 168 that is received in a suitable recess (not shown) preformed in wall 12.
Referring back to the device 10A, the side pieces and 122 may be formed of any suitable material,
though a resiliently flexible plastic is preferred.
The side pieces 120 and 122 are generally planar in configuration and each include a rounded forward edge 250 and a rearward edge 252 (see FIG. of rectilinear configuration. At the upper and lower ends 254 and 256 of the side pieces 120 and 122, lugs 158 and 160 are provided which are intended to fit behind the frame 102 and against its rear surface (not shown). For this purpose side pieces 120 and 122 are made resiliently flexible so that they can be flexed sufficiently to be slipped into place with the lugs 258 and 260 behind the rear side of the frame 102.
As indicated, side pieces 120 and 122 are each formed with bosses 124 that slip into and substantially complement the recesses 114 of the arms 106 and 108, respectively, of the conventional frame 102. Bosses 124 are indented as at 124A to receive the respective casings 130 for latching purposes.
Cover 32A comprises a curved wall 270 that is struck about an arc that is concentric with the axis 129 about which roll 14 rotates when applied to journaling assemblies 22A and 24A. Cover 32A also includes substantially planar side walls 274 and 276 in which the respective journaling assemblies 22A and 24A are mounted, and which include the respective extensions 278 and 280 that are pivotally connected to the respective side pieces 120 and 122 by cross rod 282 on which rollers 142 are journaled. Cross rod 282 has its ends 284 suitably fixed in the respective side pieces 120 and 122.
Cross rod 286 extending between the cover side walls 274 and 276 journals the rollers 140. Rollers 140 and 142 may be held against movement lengthwise of their respective journaling rods in any suitable manner, as by employing suitable stopping lugs and the rods, lock rings, or the like, as will be obvious to those skilled in the mechanical arts. When the cover 32 is moved to its closed position, a paper 82 extends between the rollers 140 and 142 in the manner indicated in FIG. 8.
Referring now more specifically to the journaling assembly 22A, the casing 130 thereof is received in opening 290 formed in the cover side wall 274. The casing 130 comprises a generally rounded rim or side wall 292 integrally united with end wall 294, with the rim 292 and wall 294 being suitably shaped at one side of the casing to define the cam surface 136. The rim or side wall 292 is formed with opposed slots 296 and 298 in which are received opposing pins 300 and 302 suitably fixed to the cover side wall 274, as by soldering or employing a suitable adhesive where indicated at 304 and 306, respectively.
The casing 130 is also slotted as at 308 to receive pin 310 that is affixed to cover side wall 274 as by employing soldering or a suitable adhesive where indicated at 312. The movement of casing 130 relative to the cover 32A is thus guided by the three pins 300, 302 and 310, these pins being in the plane ofthe flange 274.
In the form shown, the pins 300 and 302 are longer than pin 308 and operate in the respective slots 314 and 316 of the head 134 for the purposes of guiding the movement of the head relative to the casing and precluding rotation of the head relative to the casing.
The head 132 is generally similar to head 58 of the device 10 and comprises the body 320 shaped to define spherically contoured protuberance 134 in substanmaterial tially hemispherical form, together with the flange or edge portion 322 that is in circumambient relation thereabout. The rim 292 of casing 130 is flanged as at 324 to serve as a stop engaging the head flange 322 to preclude movement of the head 132 outwardly of the casing 130 under the action of the compression spring 326 that is interposed between the head and the casing wall 294. Edge portion 325 of flange 324 is angled as at 327 to cam the casing 130 with the roll core on being extended into same.
The spring 326 is proportioned to seat on the inner ends of the pins 300 and 302 when the journaling assembly 22A is in the condition of FIGS. 9 and 10, with the result that the casing 130 is biased outwardly of cover wall 274. Pressing the head 132 inwardly of the casing 130 unseats the spring 326 from the pins 300 and 302, as indicated in FIG. 11. The pins 300 and 302 seat at the ends 340 of the respective casing slots 296 and 298 to preclude the casing 130 from being removed from flange 274 under the action of spring 326. Pin 310 has a similar action with regard to the slot 308 (see FIG. 11).
When the cover 32A is moved to its closed position, the cam surface 136 engages the edge 250 of the side piece to cam the casing from the position of FIG. 9 and 10 to the position of FIG. 12.
The head 132 is provided with suitable centering nibs 345 for guiding its movement relative to the casing 130. The journaling assembly 24A is arranged similarly to the journaling assembly 22A, the only difference being that the cam surface of its casing 130A is inclined oppositely of the cam surface 136 for insuring that the casings 130 and 130A move in opposite directions relative to the cover as the cover is opened and closed to achieve the taper roll mounting relationships that have been described.
Heads 134 and 134A serve the same snap action type releasable holding action on the roll core 18 that is described with reference to heads 58 and 64 of device 10. When cover 32A is swung from its closed position to its open position, springs 326 act to retract casing 130 and 130A from roll core 18, leaving held on heads 132 and 132A for ready snap action removal and reapplication ofa new roll 14.
It will therefore be seen that we have provided several forms of toilet paper holding dispensing device which not only insures a firm journaling of the roll and ready replaceability of'same, but also that the roll is fully masked in use. One of the significant features of this invention is that the operation of unmasking the roll sets up the device so that the roll can be readily replaced, and remasking or recovering the roll firmly journals the roll in operation position.
The foregoing description and the drawings are given merely to explain and illustrate the invention and the invention is not to be limited thereto, except insofar as the appended claims are so limited, since those skilled in the art who have the disclosure before them will be able to make modifications and variations therein without departing from the scope of the invention.
