Abstract

Abstract Magnetic holder for keys and the like embodying this invention is in the form of a unitary extrusion of synthetic plastic, magnetic material. The extrusion has a planar web portion, and a key-shaped cut-out is provided through the base portion of said magnetic material. The extrusion includes longitudinal, inwardly opening side edge channels, and the sheet is slidably insertable within said channels as a closure for one side of said key shaped cut-out. Also disclosed is a method of manufacturing such key holders which includes the steps of extruding a unitary, continuous strip of synthetic plastic magnetic material with a planar web portion and inturned longitudinal edge channels. A key-shaped cut-out is punched through the web portion of the magnetic strip, and a flat panel is fitted over one side of the key-shaped cut-out, with the edges of the panel disposed in said channels.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 68 words
Magnetic holder for storing a key or other small article by magnetically attaching the holder to a ferrous metal surface comprising an integral strip of magnetic plastic material, said strip including a flat central web portion and inturned side edge channels, said web portion including a cut-out therethrough having a size and shape to accommodate said key or other object when oriented in the plane of said web.
Claim 2
Dependent Claim 68 words
Magnetic holder for storing a key or other small article by magnetically attaching the holder to a ferrous metal surface comprising an integral strip of magnetic plastic material, said strip including a flat central web portion and inturned side edge channels, said web portion including a cut-out therethrough having a size and shape to accommodate said key or other object when oriented in the plane of said web.
Claim 3
Dependent Claim 38 words
Magnetic holder as set forth in claim 1 in which a sheet is disposed against one surface of said web and is retained therein by its edges being fitted into the edge channels of said magnetic plastic strip.
Claim 4
Dependent Claim 17 words
Magnetic holder as set forth in claim 1 in which said magnetic plastic strip is an extrusion.
Claim 5
Dependent Claim 29 words
Magnetic holder as set forth in claim 2 in which said sheet includes a transparent outer layer for the visual display of indicia imprinted on a card disposed thereunder.
Claim 6
Dependent Claim 115 words
Method of manufacturing magnetic holders for the storage of keys and the like by magnetically attaching the holder to a ferrous metal surface, the method comprising the steps of extruding a synthetic plastic magnetic material into a unitary, continous strip having a flat central web portion and longitudinal edge portions which are inturned and form oppositely opening channels, cutting said strip transversely into a plurality of individual holders and making a cut-out through said web portion of a size and shape to accommodate a key or the like when oriented in the plane of said web and inserting against one surface of said web a cover sheet having its edges retained by said edge channels.
Claim 7
Dependent Claim 115 words
Method of manufacturing magnetic holders for the storage of keys and the like by magnetically attaching the holder to a ferrous metal surface, the method comprising the steps of extruding a synthetic plastic magnetic material into a unitary, continous strip having a flat central web portion and longitudinal edge portions which are inturned and form oppositely opening channels, cutting said strip transversely into a plurality of individual holders and making a cut-out through said web portion of a size and shape to accommodate a key or the like when oriented in the plane of said web and inserting against one surface of said web a cover sheet having its edges retained by said edge channels.
Claim 8
Dependent Claim 38 words
Method of making magnetic holders as set forth in claim 5 in which said cover sheet is in the form of a transparent layer for the visual display of indicia imprinted on a layer or sheet disposed thereunder.
Claim 9
Dependent Claim 74 words
Magnet holder for storing a key or other small article by magnetically attaching the holder onto a ferrous metal surface said holder comprising an extrusion of magnetic plastic material in the form of a planar strip having a cut-out therethrough to accommodate said key or other object when oriented in the plane of said web and a cover sheet affixed onto one surface of said strip to close off one side of said cut-out.
Claim 10
Dependent Claim 74 words
Magnet holder for storing a key or other small article by magnetically attaching the holder onto a ferrous metal surface said holder comprising an extrusion of magnetic plastic material in the form of a planar strip having a cut-out therethrough to accommodate said key or other object when oriented in the plane of said web and a cover sheet affixed onto one surface of said strip to close off one side of said cut-out.
Claim 11
Dependent Claim 63 words
Magnet holder as set forth in claim 7 in which said extrusion is an elongated strip with a plurality of longitudinally spaced cut-outs therethrough to accommodate in each a key or other object, said elongated strip being severable transversely to form a plurality of said key holders, said cover sheet including a transparent layer and an opaque inner layer bearing printed indication thereon.
