Abstract

An end support for supporting a roll of material wound on a tubular core is defined by a generally rectangular plate and a projecting hub member. The hub is dimensioned for insertion into a tubular core material roll. A plurality of spaced plate ribs are provided internally within the plate with at least one rib extending inwardly from each of the plate side perpendicular to the hub member. A plurality of crossing ribs are also provided and intersect with the perpendicular plate ribs and other crossing ribs to define a generally open areas lattice pattern. A plurality of corrugation surfaces are fixed to one or more of the side members, corner members, hub member, crossing ribs and plate ribs and extend into the open areas of the lattice pattern. The corrugations surfaces are alternately formed along the front and rear faces of the plate.

First claim

What is claimed is:

1. An end support for supporting a roll of material wound on a tubular core in a substantially horizontal orientation, the end support comprising:
a substantially planar plate member having a front face and a rear face; the front face and rear face being spaced from one another, the plate having an outer flange defining a number of side surfaces and the side surfaces arranged to form a generally rectangular periphery, the flange extending transverse to the plane of the plate, and an internal area defined within the periphery of the flange;
a substantially circular hub member having an outer dimension defined for insertion into a tubular core of a wound roll of material, the hub centrally positioned within the internal area of the plate and projecting outwardly in a perpendicular direction from the front face and the plane of the plate;
a plurality of spaced plate ribs formed transverse to the plane of the plate and positioned within the internal area, the plate ribs extending inwardly from the outer flange to the hub, a plurality of open areas defined between the plate ribs within the internal area of the plate, and at least one of the plate ribs extending substantially perpendicular to each rectangular side surface of the outer flange, the perpendicular plate ribs aligned with a radius of the circular hub member; and
a plurality of corrugation surfaces fixed to the plate ribs and extending from the plate ribs at least partially into the open area between the plate ribs; the corrugation surfaces alternately formed along the front and rear faces of the plate.

2. An end support as in claim 1 wherein said hub member is substantially hollow and comprises an internal wall, and wherein a plurality of hub rib portions are formed within the hub member and extend axially along the internal wall of the hub member.

3. An end support as in claim 2 wherein the hub rib portions are aligned with the perpendicular plate ribs.

4. An end support as in claim 3 wherein the hub rib portions extend radially from the internal wall only partially into the central area of the hub member.

5. An end support as in claim 1 wherein the side surfaces of the outer flange are formed by four flat side members, and wherein rounded corners connect the side members.

6. An end support as in claim 5 wherein the plate ribs further comprise a plurality of ribs extending radially between the hub member and the corners of the outer flange.

7. An end support as in claim 1 wherein the plate ribs further comprise a plurality of parallel ribs positioned within the internal area and aligned substantially parallel to the side members of the outer flange.

8. An end support as in claim 7 wherein the parallel ribs intersect with the perpendicular plate ribs.

9. An end support as in claim 8 wherein the parallel ribs and perpendicular plate ribs form an open lattice structure within the rectangular periphery and wherein the corrugation surfaces have a rectangular form within the lattice openings.

10. An end support as in claim 1 wherein the side surfaces of the plate each comprise an undulating wall portion creating a hand gripping portion for the plate.

11. An end support for supporting a roll of material wound on a tubular core in a substantially horizontal orientation, the end support comprising:
a plate having four side members, the side members forming a rectangular profile, the plate having four corners members, each corner member connecting two of the side members, and the plate having a front face and a rear face, the front and rear faces being spaced from one another by a plate thickness;
a hub member having an outer dimension defined for insertion into a tubular core of a wound roll of material, the hub centrally positioned within the rectangular profile of the plate member and projecting substantially perpendicular from the front face of the plate;
a plurality of spaced plate ribs provided internally within the rectangular profile of the plate, at least one of the plate ribs extending inwardly from each of the side members and substantially perpendicular thereto, each of the perpendicular plate ribs connected to the hub member;
wherein the side members, corner members, hub member and plate ribs define generally open areas there between within the plate; and
a plurality of corrugation surfaces fixed to one or more of the side members, corner members, hub member and plate ribs and at least partially into the open areas, the corrugation surfaces alternately formed along the front and rear faces of the plate.

12. An end support as in claim 11 further comprising a plurality of plate ribs intersecting the perpendicular plate ribs.

13. An end support as in claim 11 further comprising radius surfaces on the plate ribs at the front face and rear face of the plate.

14. An end support as in claim 11 further comprising a plurality of plate ribs angled inwardly from the side members.

15. An end support as in claim 11 further comprising corners members having outwardly convex surfaces.

16. An end support as in claim 11 wherein the hub member is generally cylindrical and comprises a substantially hollow interior.

17. An end support as in claim 16 wherein the perpendicular plate ribs are aligned with a radius of the cylindrical hub member.

18. An end support as in claim 17 wherein said hub member comprises a plurality of hub rib portions formed along an internal wall portion within the hollow of the cylindrical hub member.

19. An end support as in claim 18 wherein a number of the hub rib portions are aligned with the perpendicular plate ribs.

20. An end support as in claim 19 wherein the hub rib portions extend only partially from the internal wall portion into the central area of the hub member.
