Abstract

A paper roll support assembly is provided with a collapsible spindle with distal ends to be received in a pair of bracket receptacles. Product packaging is sized to receive the collapsible spindle only in a collapsed state of the spindle to minimize an overall size. The collapsible spindle is provided with an outer spindle member, an open end spaced apart from the distal end, and a cavity formed therein with a first diameter. An inner spindle member is provided with a proximal end spaced apart from the distal end with an outer diameter sized to be received within the cavity for translation and rotation relative to the outer spindle. A first retainer is oriented in the cavity in cooperation with a second retainer oriented on the inner spindle member such that extension is prevented in a first rotational orientation and extension is permitted in a second rotational orientation.

First claim

What is claimed is:

1. A packaged paper roll support assembly comprising:
a pair of brackets to mount to a support surface, each bracket having a receptacle formed therein;
a collapsible spindle with a pair of distal ends sized to be received in the pair of bracket receptacles to support a paper roll on the spindle;
a box with panels that define a cavity, wherein a pair of the panels are spaced apart to receive the collapsible spindle only in a collapsed state and disassembled from the pair of brackets, and wherein the box is sized to receive the pair of brackets; and
a sheet sized to receive the collapsible spindle only in the collapsed state of the collapsible spindle, which is less than an overall length of the collapsible spindle, to retain the collapsible spindle in the collapsed state to minimize an overall size of the collapsible spindle in the collapsed state.

2. The packaged paper roll support assembly of claim 1 further comprising a flexible tie member cooperating with the pair of distal ends of the collapsible spindle to retain the collapsible spindle in the collapsed state.

3. The packaged paper roll support assembly of claim 1 wherein the collapsible spindle comprises:
an outer spindle member with one of the pair of distal ends of the collapsible spindle, an open end spaced apart from the distal end, a cavity formed within the outer spindle member with a first diameter, and a first retainer oriented within the cavity; and
an inner spindle member with the other of the pair of distal ends of the collapsible spindle, a proximal end spaced apart from the distal end with an outer diameter sized to be received within the cavity for translation and rotation relative to the outer spindle, and a second retainer oriented on the inner spindle member in cooperation with the first retainer such that extension of the inner spindle member relative to the outer spindle is prevented in a first rotational orientation of the inner spindle member relative to the outer spindle member and extension of the inner spindle member relative to the outer spindle member is permitted in a second rotational orientation of the inner spindle member relative to the outer spindle member.

4. The packaged paper roll support assembly of claim 1 wherein the collapsible spindle comprises a pair of trunnions each oriented on one of the pair of distal ends that are each sized to be received in one of the pair of receptacles.

5. The packaged paper roll support assembly of claim 4 wherein the sheet is provided with a pair of spaced apart apertures sized to receive the pair of trunnions to retain the collapsible spindle in the collapsed state.

6. The packaged paper roll support assembly of claim 5 wherein the sheet is formed from a polymeric material.

7. The packaged paper roll support assembly of claim 3 further comprising a biasing member oriented within the cavity in cooperation with a blind depth of the cavity and the proximal end of the inner spindle member to bias the inner spindle member towards extension relative to the outer spindle member.

8. The packaged paper roll support assembly of claim 3 wherein the first retainer comprises an array of annular segments oriented in the cavity proximate to the open end, each spaced apart radially;
wherein the inner spindle member has a portion with a reduced diameter extending distally from the proximal end; and
wherein the second retainer comprises an array of longitudinal extensions along the reduced diameter portion of the inner spindle member in cooperation with the array of annular segments in the first rotational orientation of the inner spindle member relative to the outer spindle member, and to align with spaces between the array of annular segments in the second rotational orientation of the inner spindle member relative to the outer spindle member.

9. The packaged paper roll support assembly of claim 8 wherein the array of annular segments comprises four annular segments; and
wherein the array of longitudinal extensions comprises four longitudinal segments.

10. The packaged paper roll support assembly of claim 8 wherein a detent is formed in each of the array of annular segments facing the distal end of the outer spindle member, each detent sized to receive one of the array of longitudinal extensions to limit rotation of the inner spindle member relative to the outer spindle member.

11. The packaged paper roll support assembly of claim 1 wherein the collapsible spindle is collapsed at least thirty-three percent in the collapsed state relative to the overall length of the collapsible spindle.

12. The packaged paper roll support assembly of claim 1 wherein the sheet prevents distribution of a tensile load from the collapsible spindle in the collapsed state to the box.

13. The packaged paper roll support assembly of claim 12 wherein the box is formed from cardboard.

14. A packaged paper roll support assembly comprising:
a pair of brackets to mount to a support surface, each bracket having a receptacle formed therein;
a collapsible spindle with a pair of distal ends sized to be received in the pair of bracket receptacles to support a paper roll on the spindle;
a box with panels that define a cavity, wherein a pair of the panels are spaced apart to receive the collapsible spindle only in a collapsed state and disassembled from the pair of brackets, and wherein the box is sized to receive the pair of brackets; and
a sheet sized to receive the collapsible spindle only in the collapsed state of the collapsible spindle, which is less than an overall length of the collapsible spindle, to retain the collapsible spindle in the collapsed state to minimize an overall size of the collapsible spindle in the collapsed state;
wherein the collapsible spindle comprises a pair of trunnions each oriented on one of the pair of distal ends that are each sized to be received in one of the pair of receptacles;
wherein the sheet is provided with a pair of spaced apart apertures sized to receive the pair of trunnions to retain the collapsible spindle in the collapsed state;
wherein the sheet is formed from a polymeric material;
wherein the collapsible spindle is collapsed at least thirty-three percent in the collapsed state relative to the overall length of the collapsible spindle;
wherein the sheet prevents distribution of a tensile load from the collapsible spindle in the collapsed state to the box; and
wherein the box is formed from cardboard.
