Rotatable wheel assembly
摘要:
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.
