This disclosure relates to spindles for supporting a roll of paper products in a dispenser, such as toilet paper and paper towels.
Spindles for supporting paper product rolls in a dispenser are known.
However, known spindles often lack versatility as they are often dispenser specific and usable in only one brand or type of dispenser.
In addition, some prior spindles become skewed when used in plural roll dispensers, making it more difficult to retrieve paper from the dispenser.
Therefore, for these and other reasons a need exists for improve paper roll spindles.
A spindle assembly for supporting a roll of paper product is disclosed with features that make the spindle versatile and useable for supporting paper product rolls in a plurality of styles of dispensers. A combination of rings and spindle portions of differing cross sectional dimensions, such as of different diameters, are positioned in a way that allows the spindle assembly to be received in different dispensers. The spindle assembly also includes features that assist in maintaining the supported paper rolls in a desired orientation, such as horizontally in a vertically oriented dispenser. This resists skewing of the rolls in the dispenser and facilitates the separation of the rolls as paper is used from a lower roll in a dispenser. As a desirable example, a spring biases enlarged end portions, such as respective rings, at the outer ends of rod and sleeve portions of a spindle assembly that are positioned within a dispenser slot against surfaces of the dispenser to assist in retaining the spindle assembly and supported paper roll in the desired orientation.
A brake can be incorporated into the spindle to increase friction between a supported paper roll and the spindle to reduce the tendency of the roll to over spin and dispense excess paper when the exposed end of the paper roll is grabbed and pulled by a user.
The paper roll can be supported on the spindle assembly between a first large ring on the sleeve portion and a second large ring on a rod portion. The sleeve portion includes a rod receiving passageway and the rod portion includes a rod body with a distal end portion sized for insertion into the rod receiving passageway. A biasing spring within the rod receiving passageway is compressed as the distal end portion of the rod body is inserted into the rod receiving passageway. By varying the depth of insertion of the distal end portion into the rod receiving passageway, the axial length of the spindle assembly is varied such that the assembly can be used in dispensers of different widths.
In accordance with more specific aspects of an embodiment of this disclosure, a spindle assembly is disclosed for supporting a roll of paper product in a paper product dispenser, the roll of paper product having a spindle receiving core with an inner core diameter. The spindle assembly can comprise a sleeve body having first and second sleeve body ends and a sleeve body longitudinal axis, the sleeve body having a rod receiving passageway extending through the first sleeve body end and axially into the sleeve body. In addition, a first ring extends outwardly from the sleeve body and has a first outer diameter. The first ring is positioned between the first and second sleeve body ends and nearer to the second sleeve body end than to the first sleeve body end. The spindle assembly of this embodiment can comprise a second ring that extends outwardly from the sleeve body and that is positioned at the second sleeve body end. The second diameter can be less than the first outer diameter. In addition, in this embodiment, the portion of the sleeve body between the first and second rings can have an outer diameter that is less than the second outer diameter. A biasing spring is also positioned within the rod receiving passageway. In addition, the embodiment includes a rod body having first and second rod body ends and a rod body longitudinal axis. A third ring can extend outwardly from the rod body and can have a third outer diameter, the third ring being positioned between the first rod body end and the second rod body end and nearer to the second rod body end than to the first rod body end. At least one fourth ring can extend outwardly from the rod body between the first rod body end and the third ring and the at least one fourth ring can have a fourth outer diameter that is less than the third outer. In this embodiment, a fifth ring extends outwardly from the rod body and can have a fifth outer diameter; the fifth ring being located at the second rod body end and the fifth outer diameter can be less than the third outer diameter. Furthermore, in this embodiment, the portion of the rod body between the third and fifth rings can have an outer diameter that is less than the fifth outer diameter. Moreover, the rod body can comprise a spindle rod portion between the at least one fourth ring and the first end of the rod body. The first end of the rod body also comprises a first end of the spindle rod portion. The first end of the spindle rod portion and the spindle rod have a cross sectional dimension that is sized to permit sliding of the spindle rod portion into and along the rod receiving passageway upon assembly of the sleeve body and rod body into the spindle assembly, the first end of the spindle rod portion engaging the biasing spring and compressing the engaged biasing spring as the spindle rod portion is inserted into the rod receiving passageway, the compressed biasing spring applying a force that urges the second and fifth rings away from one another and against portions of the dispenser.
In accordance with additional aspects of this disclosure, the spindle assembly can have first and third rings with respective first and third outer diameters that are equal to one another. In addition at least a portion of the sleeve body between the first ring and the first sleeve body end can have an outer diameter that is equal to the fourth outer diameter.
As a further aspect of this disclosure, a spindle assembly can have a sleeve body between the first ring and first sleeve body end, apart from any openings or recesses formed in the sleeve body, is a right cylinder.
As yet another aspect of this disclosure, each of the rings of the spindle assembly can be annular, coaxial and have a geometric center intersected by the longitudinal axis of the assembled spindle assembly. These rings can project perpendicularly outwardly from the longitudinal axis.
As a further aspect of this disclosure, the spindle assembly desirably includes at least one brake element or member positioned to engage the interior core of a paper roll when positioned on the spindle. The brake element provides friction against the interior core of the paper roll and limits the rate of rotation of the paper roll when a user engages and pulls on the end of the paper roll. The brake member can be annular and desirably has a cross sectional dimension that is less than the cross-sectional dimension of the paper roll core. Desirably there is at least one brake member positioned on each of the rod body and sleeve body. The brake member on the sleeve body is desirably positioned between the first ring and the first sleeve body end. In addition, the brake member on the rod body is desirably positioned between the third ring and the first rod body end and more desirably between the fourth ring and the first rod body end. The brake members can comprise elastomeric members, such as rings. O-rings or O-bands are a specific example. In one specific form, each of the brake members comprises a plurality of O-rings of rubber that are positioned side by side on the respective sleeve and rod bodies. For example, each brake member can comprise a set of three O-rings. The brake members can be held axially in position by adhesive. Alternatively, they can be positioned in a seat with respective wall portions at the axial ends of each seat. The seats can comprise a recess in the sleeve body. In addition, the seat in the rod body can be positioned in a portion of the rod body that is enlarged in cross-sectional dimension, such as an annular portion spaced from the first end of the rod body that has the same diameter as the fourth ring. The distal end of the rod body seat nearest to the first end of the rod body can be tapered, such as frustoconical, to facilitate insertion into the interior of the paper roll. In addition, the first end or distal end of the sleeve body can also be tapered, such as frustoconical for the same reason.
Desirably, the distal end of the sleeve body and the distal end of the rod body are spaced apart by a gap when the spring is fully compressed.
In accordance with an embodiment, the dispenser can comprise a toilet paper dispenser comprising a housing having a first side wall with a first channel mounted to the first side wall and a second side wall opposed to the first side wall, a second channel being mounted to the second side wall, the first channel having a first spindle receiving slot and the second channel having a second spindle receiving slot facing the first spindle receiving slot, the second spindle receiving slot being spaced from the first spindle receiving slot by a spacing distance that is less than the distance between the second end of the sleeve body and the second end of the rod body when the spindle rod portion is inserted into the rod receiving passageway and the spindle rod portion has not compressed the spring, the spacing distance also being greater than the distance between the second end of the sleeve body and the second end of the rod body when the spindle rod portion is inserted a maximum distance into the rod receiving passageway and compresses the spring. A toilet paper roll is carried by the spindle assembly with a first ring being positioned between the first channel and the toilet paper roll and a third ring being positioned between the second channel and the toilet paper roll. The toilet paper roll is thus positioned between the first and third rings and supported by brake elements between the first and third rings. In addition, second and fifth rings of the spindle assembly are respectively positioned in the first and second slots to load the toilet paper dispenser with the roll of toilet paper. A biasing spring urges the second and fifth rings against surfaces of the channels or of the dispenser to hold the toilet paper roll in a desired orientation in the dispenser.
