Abstract

A device for securing a strip of material to a spool having a longitudinal slot with undercut lips on each side of the slot. The device comprises a rod formed with a pair of intermediate sections pivotally engaging a loop at the end of the strip of material. A pair of legs project, one from each extreme end of the intermediate sections. The rod is bent centrally to form a stop tab to coact with a notch in the spool. The device is inserted into the slot and twisted to engage under the lips, and will resist pull-out irrespective of the direction of pull on the strip.

Claims

1. In combination, a strip of material and a member for securing the end of said strip to a spool said spool having an elongated slot extending in an axial direction with an undercut lip on at least one side of said slot, said strip securing member configured to reside in said slot, said member having a dimension in one transverse direction greater than the width of the opening of the slot and less than the depth of the slot and a dimension in the other transverse direction less than the width of the opening of the slot, said member having means engaging the strip to cause the strip to eminate from one side of said member in the longer transverse direction thereof, and means to limit the amount of rotation of said member in the slot in a direction to bring said one side toward the opening in the slot.

2. The invention as defined in claim 1, wherein said means to engage said strip includes means to pivotally engage a loop of the strip.

3. In combination, an elongated strip of material having a loop in one end thereof, and a device for securing said strip of material to a spool having an elongated axially extending open slot with an undercut lip on at least one side of said opening, said member including an intermediate rod section pivotally engaging said loop and a pair of legs at the opposite ends of said intermediate section extending transversely of said intermediate section, and means to limit the amount of rotation of said member in one direction when the member resides in the slot, said limit of said rotation being at a location with the legs disposed under said lip.

4. The invention as defined in claim 3 wherein said spool has a notch extending circumferentially from said slot, and said means to limit rotation is a tab at said intermediate section extending transversely of said rod, and the loop of said material has a cut-out portion through which said tab projects, said tab being shaped and configured to reside in said notch.

5. The invention as defined in claim 4 wherein said legs lie on a common plane with said intermedIate section and said tab lies, at least in part, on a plane non-common to the plane of said legs and intermediate section.

6. The invention as defined in claim 4 wherein said tab is formed by said rod being bent.

7. The invention as defined in claim 3 wherein said legs are formed by said rod being bent.

8. A device for securing an elongated strip of material to a spool in a slot thereon, having undercut lips, said device comprising, intermediate rod sections for pivotally engaging the end of a strip of material, legs extending from the opposite ends of said intermediate section transverse thereto, and stop means formed on said central section and extending transverse thereto.

9. The invention as defined in claim 8 wherein said legs and said intermediate rod section have a common plane, and said stop means lies at least in part on a plane non-common thereto.
