The rotatable wheel assembly includes a wheel member rotatably sandwiched between a pair of cover members. Grommetless securing means are provided on at least one of the cover members for securing it to the other cover member through an axial opening in the wheel member. The grommetless securing means, which in one embodiment constitute an adhesive patch formed on at least one of the cover members, also function as a pivot for rotation of the wheel member with respect to the cover members. In other embodiments of the invention, the grommetless securing means comprise an adhesive patch member, which can be formed as an appendage to one of the cover members, that spans an opening in one of the cover members to adhere to the other cover member through the axial wheel opening. In a further embodiment of the invention the grommetless securing means comprise tab members formed on one of the cover members to extend through the axial wheel opening and a tab reception opening in the other cover member for folding thereon. A sheet construction for the rotatable wheel assembly includes the wheel member and cover member in side-by-side relationship with separation and fold lines to facilitate arrangement of the construction into a rotatable wheel assembly. Mass production of the construction blank can be accomplished on a web wherein all separation and fold lines lie in the direction of movement of the web.
A rotatable wheel assembly comprising a pair of generally flat oppositely disposed parallel cover members, a generally flat wheel member sandwiched between said oppositely disposed cover members, said wheel member having an axis of rotation substantially perpendicular to the oppositely disposed cover members and including an axial opening encompassing said axis of rotation, the axial opening of said wheel member not encompassing any pivot disc that is contiguous with said wheel member, and grommetless securing means on at least one of said cover members for securing said one cover member to said other cover member through said axial opening in said wheel member such that the securance of said cover members through said axial opening forms a pivot for rotation of said wheel member substantially about said axis with respect to said cover members.
A construction for a wheel assembly comprising a sheet of generally flat flexible foldable material including a wheel member and a pair of cover members formed therein in integral side by side relationship, the wheel member having an axial opening and at least one of the cover members having a securance opening alignable with the axial opening of said wheel member when said construction is in an operable assembled condition, said other cover member incorporating a securance portion alignable with the axial opening of said wheel member when said construction is in said operable assembled condition, said axial opening, said securance opening and said securance portion being disposed colinear in said construction, and grommetless securing means on one of said cover members for securing said one cover member to said other cover member through said axial opening in said wheel member when said construction is in said operable assembled condition.
