Abstract

A rod assembly for mounting a roll of sheet material within its own box including a rod member with a cylindrical bearing and an enlarged diameter end-cap which collectively form a first component, and a second component collectively formed by a matching bearing and end-cap having an axial slot for removably receiving the rod member. After initial perforation of the panels at the end of the box by the rod member, the two components are insertable through and mounted in such end panels so that both bearings are journaled inside the open ends of the roll when the rod member is received in the axial slot. When the roll becomes empty, the two components can be manually pulled apart and reused by being compressed together into mounting engagement inside a full roll of material in another box.

Claims

1. A portable rod assembly for providing supplemental mounting of a roll of sheet material which is already housed in a storage box, in order to facilitate dispensing the sheet material without the need of or the risk of the roll being removed from the box, comprising:

small diameter rod means for inserting through the roll of sheet material including tapered tip means on at least one end for initially perforating opposite panels at the ends of the box containing the roll of material;

a pair of bearing members each having central bearing means of substantially constant diameter which is more than the diameter of said rod means and less than the diameter of the roll of material and further including tapered bevel means on the forward end which are manually insertable through opposite panels at the end of the box, respectively, into the roll for making enlarged perforations to receive said bearing members, with adjacent portions of said central bearing means capable of loosely journaling the roll of material during its rotation to retain the roll inside the box while also holding the roll in a suspended position off the bottom of the box and snugly engaging the edges of the box perforations formed by said tapered bevel means;

cap members having a diameter greater than the diameter of said central bearing means and carried on the outer ends of said bearing members, respectively;

said rod means extending between said pair of bearing members for holding said bearing members together in mounted position in the aforesaid box panels with said cap members a predetermined distance apart outside the aforesaid box panels; and

attachment means removably connecting at least one of said bearing members to said rod means for coupling the rod assembly together into an integral unit with the box during use and to enable the rod assembly to be disengaged after use from a box having an empty roll of material and reinserted into another box having a full roll of material.

2. The device of claim 1 wherein said rod means includes a free end and a non-free end, and carries one of said bearing members and one of said cap members on its non-free end to collectively from one assembly component;

and

wherein the other ones of said bearing and cap members carry said attachment means to collectively form a second assembly component; and

wherein said attachment means receives said free end of said rod means to hold said bearing members together in mounted position passing through the box to inside the roll.

3. The device of claim 1 wherein said rod means includes longitudinal adjustment means for varying the predetermined distance between said cap members to accomodate differently sized boxes and/or to accomodate wall-mounted brackets for holding the boxed rolls.

4. The device of claim 1 wherein both of said cap members are close-ended on their outer surface to prevent said rod means from extending outwardly beyond said cap members.

5. A method of removably mounting a pair of bevel-headed bearing components through opposite ends of a box to journal a hollow roll of material in suspended position inside the box without having to remove the hollow roll of material from the box, including the steps of:

manually grasping a box in one hand and placing a free end of a rod carrying a first bearing so that the free end is adjacent to the box;

perforating the central portion of both ends of the box at points aligned with the open ends of the hollow roll of material, including a first perforating step of inserting the rod and at least partially pushing the beveled head of the first bearing through a first box end, followed by the step of withdrawing the first bearing and its attached rod from the first box end and leaving an aperture in the first box end at least partially communicating with the interior of the hollow roll, and a second perforating step of inserting the rod and at least partially pushing the beveled head of the first bearing through a second box end to bring the rod into the hollow roll;

aligning longitudinally the bearing components including inserting and at least partially pushing the beveled head of the second bearing through the aperture in the first box end into the hollow roll; and

manually compressing the two bearing components toward each other to frictionally engage the free end of the rod with the second bearing and to bring a non-beveled bearing surface of both bearing components into snug engagement in the apertures formed by said perforating steps and to engage the beveled heads of both bearings into opposite ends of the hollow roll of material to raise the roll from the bottom of the box while at the same time securely holding the roll inside the box before, during and after material is dispensed from the roll.

6. The method of claim 5 wherein said aligning step includes protruding the free end of the rod out through the aperture in the fist box end to facilitate its engagement by the second bearing during said manually compressing step.

7. The method of claim 5 wherein said manually compressing step includes pushing the beveled heads of both bearing components sufficiently into opposite ends of the hollow roll to bring a portion of the non-beveled bearing surface of both bearing components into loose supporting relationship with the inside of the hollow roll.
