Abstract
A handle attachment structure primarily designed for use for the gripping of opposite sides, but at least one side wall, of a cardboard or like penetrable material box of the type intended to carry computer paper or like material and including two leaves at least one of which is provided with supporting teeth on its inwardly facing surface thereof for the penetrating engagement of the side wall of the box. A handle means is movably attached to the leaves and is selectively positionable into and out of a coplanar position with the wall being gripped, the latter coplanar position defining a lifting position of the handle relative to the box and leaves.
Claims12
A handle attachment for a cardboard box having at least one flat side wall, comprising:
- (a) an inner leaf and outer leaf removably connected to the flat side wall and at least partially defining a hinge means for movably interconnecting said inner and outer leaves to one another,
- (b) each leaf including a facing surface positioned to engage a corresponding one of an inner and outer surface of the flat wall, a plurality of teeth formed on at least one of said facing surfaces and extending angularly outwardly therefrom and into penetrating engagement with the corresponding surface of the flat side wall,
- (c) said hinge means further including spring means disposed in biasing relation to said inner and outer leaves for urging said leaves towards each other, whereby said plurality of teeth are forced into penetrating engagement with the flat side wall, and
- (d) handle means for lifting the box pivotally connected to said hinge means and selectively positionable into and out of a substantially coplanar position relative to the side wall, said substantially coplanar position of said handle means relative to the flat side wall defining a lifting position of said handle means and said handle means being swingable into overlaying relation of the box wall defining a stored position.
