CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims benefit under 25 U.S.C. 119(e) of U.S. Provisional Application Ser. No. 61/725,217, filed Nov. 12, 2012, the entirety of which is incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates generally to dispensers for rotatably supporting toilet paper or other rolled paper products, and more particularly to a dispenser with unique anti-theft and anti-waste features that prevent removal of the roll support member until the roll is substantially empty and inhibit or allow rotation of the roll depending on a direction in which force is applied to the roll by the user.

BACKGROUND OF THE INVENTION

A known problem with toilet paper dispensers used in public washrooms are theft of toilet paper rolls, and deployment of wasted sheets from toilet paper rolls, each of which has a cost to the provider who keeps the washroom supplies stocked.

Applicant has developed a unique dispenser that provides anti-theft and anti-waste functionality without the need for keys or specialized tools to facilitate replacement of an empty roll.

SUMMARY

OF THE INVENTION

According to a first aspect of the invention there is provided a paper roll dispenser for supporting a roll of paper product for dispensing of pieces of said product from off said roll, the dispenser comprising:

a first and second channel members extending parallel to one another in a first direction and being spaced apart from one another in a second direction perpendicular to said first direction, each channel member defining a respective channel that has a length running in the first direction and is bordered by channel walls running in the first direction on three respective sides of the channel, the channel walls of each channel member comprising a central channel wall disposed at an outer side of the channel member opposite the other channel member and two side channels walls projecting from said central channel toward the other channel member at spaced apart positions leaving a fourth side of the channel open at an inner side of the channel member opposite the central channel wall, the inner sides of the two channel members being spaced apart by a first distance that only slightly exceeds an axial length of the roll of paper product, and access to each channel at longitudinal ends thereof being closed off;

an insertion feature opening into the channel of the first channel member through the central channel wall thereof;

an elongated support member having axial length that is greater than the first distance between the inner sides of the two channel members and less than a second distance between the central channel walls of the channel members, and a cross-section sized and shaped for axial passage of at least one end of the elongated supported member through the opening in the first channel member with only a slight clearance, and also through an axial hole of the roll of paper product;

whereby the roll of paper product is supportable on the dispenser by using the insertion feature to place the elongated support member in an installed position placing the opposite ends of the elongated support member respectively in the channels of the channel members with the roll rotatably disposed around the support member for support between the channel members.

Preferably the elongate support member is slidable back and forth in the channels in first direction.

Preferably the channel members are horizontally spaced apart and obliquely positioned to slope upwardly away from a connecting feature that joins together lower ends of the two channel members.

Preferably the connecting feature is part of a mounting bracket for attaching the paper roll dispenser to an upright surface of a support structure, the channel members projecting to one side of said mounting bracket to extend outwardly away from said support structure.

Preferably the central channel wall of the second channel member lacks a sufficiently sized opening for insertion of the elongate support member therein.

Preferably the second channel member is fully closed at the outer side of said second channel member.

Preferably a width of each channel between the side walls thereof is no greater than a diameter of the axial hole of the roll of paper product.

Preferably a width of the elongate support member is less than the length of each channel.

In one embodiment, the width of the elongate support member is greater than a width of each channel, as measured between the channel side walls. In such an embodiment, the support member may comprise a bar of greater length than width and greater width than thickness, and the insertion feature in the central channel wall of the first channel member may be an elongated slot running lengthwise in the first direction.

In another embodiment, the elongate support member is a cylindrical member, a diameter of which defines the width of the elongated support member and is less than the width of each channel. In such an embodiment, the insertion feature in the central channel wall of the first channel member is preferably a circular through-hole.

Preferably the insertion feature in the central channel wall of the first channel member is spaced above a bottom one of the side walls of the channel of said first channel member to prevent alignment of the elongated support member with said insertion feature when said elongated support member lies on said bottom one of the side walls.

According to a second aspect of the invention there is provided a paper roll dispenser for supporting a roll of paper product for dispensing of pieces of said product from off said roll, the dispenser comprising:

a first and second channel members extending parallel to one another in a first direction and being spaced apart from one another in a second direction perpendicular to said first direction, each channel member defining a respective channel that has a length running in the first direction and is bordered by channel walls running in the first direction on three respective sides of the channel, the channel walls of each channel member comprising a central channel wall disposed at an outer side of the channel member opposite the other channel member and two side channels walls projecting from said central channel toward the other channel member at spaced apart positions leaving a fourth side of the channel open at an inner side of the channel member opposite the central channel wall, the inner sides of the two channel members being spaced apart by a first distance that only slightly exceeds an axial length of the roll of paper product, and access to each channel at longitudinal ends thereof being closed off;

an opening extending into the channel of the first channel member through the central channel wall thereof;

an elongated support member having axial length that is greater than the first distance between the inner sides of the two channel members and less than a second distance between the central channel walls of the channel members, and a cross-section sized for axial passage of the elongated supported member through the opening in the first channel member with only a slight clearance, and also through an axial hole of the roll of paper product;

whereby the roll of paper product is supportable on the dispenser by receipt of the roll between the channel members with the axial hole of the roll aligned with the opening in the first channel member and passage of the elongated support member through the aligned opening and axial hole to place opposite ends of the elongated support member respectively in the channels of the channel members to rotatably support the roll between the channel members on the elongate support member.

According to a third aspect of the invention there is provided a paper roll dispenser for supporting a roll of paper product for dispensing of pieces of said product from off said roll, the dispenser comprising:

a first and second channel members extending parallel to one another in a first direction and being spaced apart from one another in a second direction perpendicular to said first direction, each channel member defining a respective channel that has a length running in the first direction and is open at an inner side of the channel member facing toward the other channel member, the inner sides of the two channel members being spaced apart by a first distance that exceeds an axial length of the roll of paper product;

an elongated support member having axial length that is greater than the first distance between the inner sides of the two channel members and less than a second distance between the central channel walls of the channel members, and a cross-sectional size that is less than the axial length and sufficiently small for axial passage of the elongated supported member through an axial hole of the roll of paper product, opposite ends of the elongated support member being respectively receivable in the channels in a condition slidable back and forth in the channels in the first direction.

For use, the paper roll dispenser is mounted in an installed position on an upright support structure, wherein the channels of the channel members are positioned to slope upwardly away from the upright support structure, whereby downward pulling of a free end of the roll will act to force the roll downwardly toward the support structure to abut the roll against a connecting feature spanning between lower ends of the channel members.

DETAILED DESCRIPTION

FIG. 1 shows the frame 10 of a toilet paper dispenser according to one embodiment of the present invention. The dispenser is mounted to the upright surface of a vertical wall or other suitable support structure by fastening of a mounting bracket 12 of the dispenser to the wall. The illustrated bracket 12 features a right angle structure 16 having a planar lower leg 16a from which a planar upper leg 16 projects perpendicularly so that flush placement of the upper leg 16b against the vertical surface of the wall or support structure places the lower leg in a position jutting horizontally outward from the wall.

First and second channel members 20a, 20b project perpendicularly from the vertically mounted upper leg 16b of the angle iron 16 from respective ends thereof in respective vertical planes. Each channel member 20a, 20b features a generally rectangular channel 22a, 22b having a longitudinal direction sloping obliquely upward from the lower end of the upper leg 16b of the right angle structure 16 in a direction moving away from the wall surface 100 at approximately forty-five to fifty degrees to the wall surface. However, other oblique angles above or below this range may alternatively be employed. Each channel 22a, 22b is bound on three sides by rectangular channel walls, particularly a top side wall 24a, 24b running along the top of the channel member, a matching bottom side wall 26a, 26b facing and lying parallel to the top side wall 24a, 24b at a distance therebelow, and a central wall 28a, 28b spanning between the side walls in a vertical plane and defining the outer side of the respective channel member. An inner side of each channel member 20a, 20b located nearest the other channel is left open, to define an open fourth side of the respective channel 22a, 22b facing toward the opposite channel member.

A distal end of each channel member 20a, 20b located furthest from the angle iron 16 and wall surface 100 is closed off by a respective end wall 30a, 30b. The proximal end of each channel member 20a, 20b nearest the wall surface is likewise closed off by the upper leg 16b of the angle iron 16, which forms a flat connection wall joining together the two channel members 20a, 20b over their full heights.

As best seen in FIG. 2, the central wall 28a of the first channel member 20a features a circular hole 34 cut therethrough to communicate the inner channel 22a of the member with the outer side thereof. The hole 34 is spaced a short height above the top surface of the bottom side wall 26a of the channel 22a. The central wall 28b of the second channel member 20b features no such hole, instead being closed over the full area of the respective channel 22b.

The channel members are horizontally spaced apart in a direction perpendicular to their obliquely oriented lengths, and parallel to the plane of the upper leg 16b of the right angle structure 16 of the mounting bracket 12, by a distance that only slightly exceeds the axial length of a roll of conventional toilet paper, for example exceeding such length by less than 3/16-inch, and preferably between 1/16-inch and ⅛-inch, inclusive. For example, for compatibility with a conventional toilet paper roll length of 4-inches, the channel members are preferably 4 1/16-inches to 4⅛-inches apart. Accordingly, as shown in FIGS. 6 to 8, a roll of toilet paper 200 can be received between the two channel members 20a, 20b in a horizontal orientation with a small clearance to allow free rotation of the roll about its horizontal axis without interference from the channel members.

Referring to FIG. 3, a roll support member 38 is provided in the form of a round cylindrical rod or bar having a length that exceeds the distance between the open inner sides of the channel members, but is less than the distance between the central channel walls 28a, 28b that define the outer sides of the two channel members. In planes perpendicular to this length of the support bar 38, the uniform circular cross section of the support bar 38 has a diameter that is only slightly less than the diameter of the circular hole 34 in the first channel member 20a. Accordingly, as shown in FIG. 3, the support bar 38 can be passed through the hole 34 from the outside of the first channel member 20a in order to axially slide the support bar 38 into a position spanning between the two channel members 20a, 20b. In such a position, each end of the support bar 38 is received in a respective one of the two channels 22a, 22b and rests atop the respective bottom wall 28a, 28b of that channel 22a, 22b.
