Marker attachment for rules

Claim 2

A marker attachment for an elongated rule or tape comprising a piece of flexible plastic sheet material formed into at least two panels integrally hinged along a hinge line and foldable over opposite sides of an elongated rule, said panels having integral tab-like projections on their distal ends with registering pencil-point receiving holes therein, and hook means integrally formed on the distal end of one of said panels for retaining said panels in their folded condition with said holes in registration, at least one of said panels having a window therein for viewing markings on said rule or tape.

Claim 3

A marker attachment for an elongated rule or tape comprising a piece of flexible plastic sheet material formed into at least two panels integrally hinged along a hinge line and foldable over opposite sides of an elongated rule, said panels having integral tab-like projections on their distal ends with registering pencil-point receiving holes therein, one of said tab-like projections has at least one retention prong integrally projecting therefrom toward the other of said tab-like projections, and said other of said tab-like projections has a prong-receiving hole therein for corresponding to each of said retention prongs, at least one of said panels having a window therein for viewing markings on said rule or tape.

Claim 4

A marker attachment for an elongated rule or tape comprising a piece of flexible plastic sheet material formed into at least two panels integrally hinged along a hinge line and foldable over opposite sides of an elongated rule, said panels having integral tab-like projections on their distal ends with registering pencil-point receiving holes therein, one of said tab-like projections has at least one retention prong integrally projecting therefrom toward the other of said tab-like projections, and said other of said tab-like projections has a prong-receiving hole therein for corresponding to each of said retention prongs, at least one of said panels having a window therein for viewing markings on said rule or tape.

Claim 5

A marker attachment for an elongated rule or tape comprising a piece of semi-rigid plastic sheet material formed into three panels one being a middle panel, another panel being a first end panel integrally hinged to one of two parallel edges on opposite sides of said middle panel, and the remaining panel being a second end panel integrally hinged to the other of said two parallel edges of said middle panel, said first of said end panels having a length permitting it to overlap said middle panel and having a tab integrally formed from the material thereof and which remains attached to said middle panel by an intermediate portion of the hinge integrally interconnecting said first end panel and said middle panel, said second end panel having a length greater than the length of each of said first end panel and said middle panel so as to have a projecting portion when said piece of flexible sheet material is wrapped around an elongated rule, said second end panel having a window opening therein through which said tab may be inserted and then folded back over onto said projecting portion of said second end panel, and said tab and said projecting portion each having a pencil-point receiving hole therein which holes are in registration when said tab is folded over onto said projecting portion of said second panel.

Claim 6

A marker attachment for an elongated rule or tape comprising a piece of semi-rigid plastic sheet material formed into three panels one being a middle panel, another panel being a first end panel integrally hinged to one of two parallel edges on opposite sides of said middle panel, and the remaining panel being a second end panel integrally hinged to the other of said two parallel edges of said middle panel, said first of said end panels having a length permitting it to overlap said middle panel and having a tab integrally formed from the material thereof and which remains attached to said middle panel by an intermediate portion of the hinge integrally interconnecting said first end panel and said middle panel, said second end panel having a length greater than the length of each of said first end panel and said middle panel so as to have a projecting portion when said piece of flexible sheet material is wrapped around an elongated rule, said second end panel having a window opening therein through which said tab may be inserted and then folded back over onto said projecting portion of said second end panel, and said tab and said projecting portion each having a pencil-point receiving hole therein which holes are in registration when said tab is folded over onto said projecting portion of said second panel.

Claim 7

The marker attachment of claim 3 wherein a piece of resilient rubber-like material is carried on a side of said middle panel so as to have frictional engagement with the confronting adjacent side of an elongated rule and thereby resist sliding movement of said marker attachment except when positively moved therealong.

Claim 8

The marker attachment of claim 3 wherein said middle panel has an integrally formed pointer projecting from said intermediate portion of the hinge integrally interconnecting said first end panel and said middle panel, said pointer being aligned with said pencil-point receiving holes.

Claim 9

The marker attachment of claim 3 wherein said tab bends around one edge of said window opening and said window opening has tab-receiving notches therein at opposite ends of said one edge of said window opening.

Claim 10

The marker attachment of claim 6 wherein said tab has a width greater than the width of said window opening but not great enough to prevent it from fitting into said tab-receiving notches.

Claim 11

The marker attachment of claim 3 wherein said projecting portion of said second end panel has a distal end portion from which a trapezoidal locking tang is formed leaving a trapezoidal opening in said distal portion through which tab may be inserted and for locking engagement with said distal portion.
