Abstract

An extendable bag roller for supporting a bag of material during removal of the material from the bag includes a bag support having a curved surface configured to support the bag of material on the curved surface and a roller that rolls along the curved surface of the bag support to squeeze the material out of the bag. The bag support includes a base defining a first portion of the curved surface of the bag support and an extension defining a second portion of the curved surface of the bag support, the extension being moveable to selectively increase and decrease the area of the curved surface of the bag support to accommodate different bag sizes.

First claim

The invention claimed is:

1. An extendable bag roller for supporting a bag of material during removal of the material from the bag, the extendable bag roller comprising:
a bag support having a curved surface configured to support the bag of material on top of the curved surface, the bag support comprising:
a base defining a first portion of the curved surface of the bag support; and
an extension defining a second portion of the curved surface of the bag support, the extension being moveable to selectively increase and decrease the area of the curved surface of the bag support to accommodate different bag sizes; and

a roller that rolls along the curved surface of the bag support to squeeze the material out of the bag.

2. The bag roller of claim 1 , wherein the roller rolls along the first portion of the curved surface of the bag support and the second portion of the curved surface of the bag support.

3. The bag roller of claim 1 , wherein the extension is moveable between a retracted position in which part of the second portion of the curved surface of the bag support is underneath the base, and an extended position in which the part of the second portion of the curved surface of the bag support is extended beyond the base to contact and support the bag of material.

4. The bag roller of claim 1 , wherein the second portion of the curved surface of the bag support is positioned underneath the base such that the extension is fully below the base when the extension is in a fully retracted position.

5. The bag roller of claim 1 , wherein the second portion of the curved surface of the bag support is substantially seamless with the first portion of the curved surface of the bag support when the extension is in an extended position.

6. The bag roller of claim 1 , wherein the second portion of the curved surface of the bag support has the same curvature as a curvature of the first portion of the curved surface of the bag support.

7. The bag roller of claim 1 , wherein the second portion of the curved surface of the bag support is about five inches (about 12.7 centimeters) in length.

8. The bag roller of claim 1 , further including graduation marks located on the extension.

9. The bag roller of claim 8 , wherein the graduation marks are holes in the second portion of the curved surface of the bag support.

10. An extendable bag roller for supporting a bag of material during removable of the material from the bag, the extendable bag roller comprising:
a bag support having a curved surface configured to support the bag of material on the curved surface, the bag support comprising:
a base defining a first portion of the curved surface of the bag support; and
an extension defining a second portion of the curved surface of the bag support, the extension being movable to selectively increase and decrease the area of the curved surface of the bag support to accommodate different bag sizes; and

a roller that rolls along the curved surface of the bag support to squeeze the material out of the bag;
wherein the extension includes:
a curved surface making up the second portion of the curved surface of the bag support;
a side connected to the curved surface of the extension at an outer end of the side;
a fastener hole extending through the side at an inner end of the side, the fastener hole configured to accept a fastener of the bag roller;
a guide hole extending through the side; and
a guide extending through the guide hole to secure the extension to the base of the bag support.

11. The bag roller of claim 10 , wherein the side of the extension is wedge shaped.

12. The bag roller of claim 10 , wherein the side of the extension is aligned with a side of the base of the bag support.

13. The bag roller of claim 10 , wherein the extension further includes a second side connected to the curved surface of the extension at an outer end of the second side, wherein the distance between the sides of the extension is less than the distance between sides of the base of the bag roller such that the sides of the extension fit between the sides of the base.

14. The bag roller of claim 10 , wherein the guide is configured to act as a forward stop to an arm of the bag roller.

15. The bag roller of claim 10 , wherein the guide is configured to move along a slot in a side of the base of the bag roller.

16. The bag roller of claim 10 , wherein the extension further includes:
a second side connected to the curved surface of the extension at an outer end of the second side;
a guide hole extending through the second side;
a guide extending through the guide hole in the second side to secure the extension to the base of the bag roller; and
a crossbar extending between guide holes in each of the sides of the extension, wherein the crossbar is coaxial with the guides and accepts the guides to fasten the extension to the base of the bag roller.

17. An extendable bag roller for supporting a bag of material during removal of the material from the bag, the extendable bag roller comprising:
a bag support having a curved surface configured to support the bag of material on the curved surface, the bag support comprising:
a base defining a first portion of the curved surface of the bag support; and
an extension defining a second portion of the curved surface of the bag support, the extension being moveable to selectively increase and decrease the area of the curved surface of the bag support to accommodate different bag sizes; and

a roller that rolls along the curved surface of the bag support to squeeze the material out of the bag;
wherein the extension is moveable between a retracted position in which part of the second portion of the curved surface of the bag support is underneath the base, and an extended position in which the part of the second portion of the curved surface of the bag support is extended beyond the base to contact and support the bag of material.

18. An extendable bag roller for supporting a bag of material during removal of the material from the bag, the extendable bag roller comprising:
a bag support having a curved surface configured to support the bag of material on the curved surface, the bag support comprising:
a base defining a first portion of the curved surface of the bag support; and
an extension defining a second portion of the curved surface of the bag support, the extension being moveable to selectively increase and decrease the area of the curved surface of the bag support to accommodate different bag sizes; and

a roller that rolls along the curved surface of the bag support to squeeze the material out of the bag;
wherein the second portion of the curved surface of the bag support is positioned underneath the base such that the extension is fully below the base when the extension is in a fully retracted position.

19. An extendable bag roller for supporting a bag of material during removal of the material from the bag, the extendable bag roller comprising:
a bag support having a curved surface configured to support the bag of material on the curved surface, the bag support comprising:
a base defining a first portion of the curved surface of the bag support; and
an extension defining a second portion of the curved surface of the bag support, the extension being moveable to selectively increase and decrease the area of the curved surface of the bag support to accommodate different bag sizes; and

a roller that rolls along the curved surface of the bag support to squeeze the material out of the bag;
wherein the second
