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 paper roll spindle assembly comprising:
an outer spindle member with a distal end, an open end spaced apart from the distal end, a cavity formed within the outer spindle member with a first diameter, and an annular array of retainer segments oriented within the cavity proximate to the open end, each spaced apart radially; and
an inner spindle member with a distal end, a proximal end spaced apart from the distal end with an outer diameter that is enlarged relative to a remainder of the inner spindle member and sized to be received within the cavity for translation and rotation relative to the outer spindle member, and a complementary array of longitudinal segments oriented on the remainder of the inner spindle member in cooperation with the annular array of retainer segments such that extension of the inner spindle member relative to the outer spindle member 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 until the proximal end of the inner spindle member engages the annular array of retainer segments.

2. The paper roll spindle assembly of claim 1 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.

3. The paper roll spindle assembly of claim 1 wherein the complementary array of longitudinal segments is in cooperation with the annular array of retainer segments to align with spaces between the annular array of retainer segments in the second rotational orientation of the inner spindle member relative to the outer spindle member.

4. The paper roll spindle assembly of claim 3 wherein the annular array of retainer segments comprises four retainer segments; and
wherein the complementary array of longitudinal segments comprises four longitudinal segments.

5. The paper roll spindle assembly of claim 3 wherein a detent is formed in each of the annular array of retainer segments facing the distal end of the outer spindle member, each detent sized to receive one of the complementary array of longitudinal segments to limit rotation of the inner spindle member relative to the outer spindle member.

6. The paper roll spindle assembly of claim 2 wherein the outer diameter of the proximal end of the inner spindle member is sized to engage the biasing member.

7. A paper roll spindle assembly comprising:
an outer spindle member with a distal end, an open end spaced apart from the distal end, a cavity formed within the outer spindle member with a first diameter;
an annular array of retainer segments oriented in the cavity proximate to the open end, each spaced apart radially;
an inner spindle member with a distal end, a proximal end spaced apart from the distal end with an outer diameter that is enlarged relative to a remainder of the inner spindle member and sized to be received within the cavity for translation and rotation relative to the outer spindle member;
a complementary array of longitudinal segments along the remainder of the inner spindle member in cooperation with the annular array of retainer segments such that extension of the inner spindle member relative to the outer spindle member is prevented in a first rotational orientation of the inner spindle member relative to the outer spindle member and;
wherein the complementary array of longitudinal segments aligns with spaces between the annular array of retainer segments in a second rotational orientation of the inner spindle member relative to the outer spindle member;
wherein extension of the inner spindle member relative to the outer spindle member is permitted in the second rotational orientation of the inner spindle member relative to the outer spindle member until the proximal end of the inner spindle member engages the annular array of retainer segments; and
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 paper roll spindle assembly of claim 7 wherein the outer diameter of the proximal end of the inner spindle member is sized to engage the biasing member.
