Spindle for roll paper products

摘要

An expandable and contractible spindle for dispensing rolled paper product, such as toilet paper, is described. The spindle comprises two elongated housings slideably coupled together, and a spring disposed there between. The first housing has a hallow interior portion and a side opening that provides access to the interior. The second housing has at least three sections with different diameters. The first section has a diameter that fits into the hollow interior of the first housing, but is too large to exit the side opening. The second section has a diameter smaller than the side opening. The third section has a diameter larger than the side opening. In this manner, first housing slides with respect to second housing along the length of the second section of second housing. The spring is disposed in the hallow interior, causing the spindle to expand.

主权项

1. A spindle for dispensing a roll of paper product, comprising:
a first elongated housing having an outer diameter, an inner diameter, and a side opening having a diameter; wherein the first elongated housing comprises first and second separate members that couple to form a hollow interior portion; a second elongated housing consisting of a first end portion, a middle portion, and a second end portion having first, second, and third outer diameters, respectively; wherein the first outer diameter of the second elongated housing is smaller than the inner diameter of the first elongated housing and larger than the side opening diameter of the first elongated housing; wherein the second outer diameter of the second elongated housing is smaller than the side opening diameter of the first elongated housing; wherein the third outer diameter of the second elongated housing is larger than the side opening diameter of the first elongated housing; wherein the second end portion has a constant diameter that extends from the middle portion to an end of the second elongated housing; and a spring having a diameter smaller than the first elongated housing inner diameter, wherein the spring is disposed in the hollow interior portion of the first elongated housing between the first elongated housing and the second elongated housing and biased to expand the first elongated housing away from the second elongated housing.
