Abstract
A device centralizes a roll of toilet tissue onto a rod or spindle. Assuming the roll of tissue has an inner diameter D and a width W, and that the rod or spindle has an outer diameter d1, the invention comprises a pair of disks and a plurality of flexible elements interconnecting the disks and maintaining the disks in spaced-apart relation. The disks are separated by a distance corresponding to W, thereby defining a cylindrical volume having a central longitudinal axis. Each disk has an outer diameter D′ slightly less than D, and an inner diameter d1′ slightly greater than d1. Each flexible element has a central section extending outwardly beyond the cylindrical volume, such that when a roll of toilet tissue is inserted over the device the elements flex inwardly toward the central longitudinal axis and achieve a frictional coupling to the roll.
Description
- This invention relates generally to bathroom tissue and, in particular, to apparatus that allows a roll of toilet tissue to be centered on a spindle.
- While there may have been a time when the inside diameter of a roll of toilet paper corresponded to the outside diameter of the rod or spindle onto which it is placed, that is no longer the case. Reference is made to
FIG. 1 , which shows a roll oftissue 108, ordinarily wound onto a cardboard tube having an inner diameter D which is much larger than the diameter ofspindle 120 upon which it is placed. This creates certain problems, especially with respect to in-wall type dispensers 101, as shown. Today, for example, the inner diameter D is typically greater than 1 inch, whereas the outside diameter ofspindle 120 is typically 1 inch or less. In particular, D may be 1½ to 1⅝ inches, whereas the outside diameter ofspindle 120 may be ¾, ⅞ or 1 inch. With the diameter D being sufficiently larger than the diameter of thespindle 120, it is not centered on the spindle, and rubbing may occur at point “X,” causing sanitation issues or sheets to tear at unwanted times. -
FIG. 2 illustrates a typical existing spring-loaded-type spindle. This spindle, also designated as 120, includes aportion 112 having an outside diameter d2 of 13/16 to 1 inch, depending upon whether metal or plastic construction is used. Theportion 112 is received by a smaller-diameter portion 116, having an outside diameter d1 of approximately ¾ inch. In any case, these dimensions are also significantly less than the inner diameter of tissue rolls, leading to the problems outlined above. - This invention solves problems of the type just described by providing a device for centralizing a roll of toilet tissue onto a rod or spindle. Assuming the roll of tissue has an inner diameter D and a width W, and that the rod or spindle has an outer diameter d1, the invention comprises a pair of disks and a plurality of flexible elements interconnecting the disks and maintaining the disks in spaced-apart relation.
- The disks are separated by a distance corresponding to W, thereby defining a cylindrical volume having a central longitudinal axis. Each disk has an outer diameter D′ slightly less than D, and an inner diameter d1′ slightly greater than d1. Each flexible element has a central section extending outwardly beyond the cylindrical volume, such that when a roll of toilet tissue is inserted over the device the elements flex inwardly toward the central longitudinal axis and achieve a frictional coupling to the roll.
- In the preferred embodiment, D is on the order of 1½ to 1⅝ inches, d1 is on the order of ¾ inch or greater, and W is on the order of 4½ inches. In the case where the rod or spindle is a spring-biased unit having a first section with an outer diameter d1 and a second section with an outer diameter d2 which is greater than d1, the disks have different inner diameters. In particular, one of the disks has an inner diameter d2′ slightly greater than d2, wherein d2 is on the order of 13/16 to ⅞ inches or greater. The preferred embodiment uses three equally spaced springy metal flexible elements.

FIG. 2 , the preferred embodiment of the invention includesdisks disk 102, to be received overportion 112 of thespindle 120, would have an inside diameter d2′ just greater than ¾ to ⅞ inch. Accordingly, d2′ would preferably be 15/16 to 1 inch, or thereabouts.Disk 104, on the other than, to be received overportion 116 ofspindle 120, would have an inside diameter 114 (d1′) slightly greater than ¾ inch. Accordingly, diameter d1′ would preferably be on the order of 13/16 to ⅞ inch, or thereabouts. - The

FIG. 4 is an end-view of the preferred embodiment ofFIG. 3 seen from the direction shown inFIG. 3 . This view is shown to illustrate how flexible elements, regardless of number, extend outwardly from diameter D′ to diameter D″ which is larger, preferably on the order of 2″. As shown, when theapparatus 100 is placed over a spindle such as 120, and inserted into a roll of tissue as shown inFIG. 5 , flexible elements such as 105, 106, 107 bend inwardly toward the overall axis of the system, thereby centering the roll on the spindle, and avoiding the problems depicted inFIG. 1 .
