Abstract
Abstract A magnetic closure for keycases, pocketbooks, wallets, and other containers which provides a positive opening as well as a closing by means of magnets with respective North and South poles so positioned as to bring opposite poles into proximity for positive closing and like poles into proximity for opening. One panel of the keycase or other container is provided with the sliding magnet and another panel of the keycase has the fixed magnet whereby manually sliding one with respect to the other causes the magnets to assume the position of similar or dissimilar polarity. The keys are held by fixed loops and a flexible wire.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
168 words
In a magnetic closure and the like, such as a keycase, wherein there is one panel which is movable relative to another panel: a. a first panel having a movable latch member thereon and a magnet movably mounted on said panel to be moved by said latch member, b. a second panel having a fixed magnet thereon opposite said movable magnet, said magnets being relatively movable with respect to each other, c. both of said magnets having North and South poles thereon and in closed condition said panels being latched by the magnetic attractions of said opposite poles being close enough to attract and said latch member being movable by hand to bring said like poles close enough to cause repulsion thereby opening said closure, said keycase having a loop member thereon with a plurality of loops therein; and a flexible key retainer member running through said loops providing other loops between said loops in said loop member, and keys strung on at least some of said loops.
Claim 2
Dependent Claim
168 words
In a magnetic closure and the like, such as a keycase, wherein there is one panel which is movable relative to another panel: a. a first panel having a movable latch member thereon and a magnet movably mounted on said panel to be moved by said latch member, b. a second panel having a fixed magnet thereon opposite said movable magnet, said magnets being relatively movable with respect to each other, c. both of said magnets having North and South poles thereon and in closed condition said panels being latched by the magnetic attractions of said opposite poles being close enough to attract and said latch member being movable by hand to bring said like poles close enough to cause repulsion thereby opening said closure, said keycase having a loop member thereon with a plurality of loops therein; and a flexible key retainer member running through said loops providing other loops between said loops in said loop member, and keys strung on at least some of said loops.
Claim 3
Dependent Claim
168 words
In a magnetic closure and the like, such as a keycase, wherein there is one panel which is movable relative to another panel: a. a first panel having a movable latch member thereon and a magnet movably mounted on said panel to be moved by said latch member, b. a second panel having a fixed magnet thereon opposite said movable magnet, said magnets being relatively movable with respect to each other, c. both of said magnets having North and South poles thereon and in closed condition said panels being latched by the magnetic attractions of said opposite poles being close enough to attract and said latch member being movable by hand to bring said like poles close enough to cause repulsion thereby opening said closure, said keycase having a loop member thereon with a plurality of loops therein; and a flexible key retainer member running through said loops providing other loops between said loops in said loop member, and keys strung on at least some of said loops.
Claim 4
Dependent Claim
168 words
In a magnetic closure and the like, such as a keycase, wherein there is one panel which is movable relative to another panel: a. a first panel having a movable latch member thereon and a magnet movably mounted on said panel to be moved by said latch member, b. a second panel having a fixed magnet thereon opposite said movable magnet, said magnets being relatively movable with respect to each other, c. both of said magnets having North and South poles thereon and in closed condition said panels being latched by the magnetic attractions of said opposite poles being close enough to attract and said latch member being movable by hand to bring said like poles close enough to cause repulsion thereby opening said closure, said keycase having a loop member thereon with a plurality of loops therein; and a flexible key retainer member running through said loops providing other loops between said loops in said loop member, and keys strung on at least some of said loops.
Claim 5
Dependent Claim
14 words
The device in claim 1: said fixed loops being formed from a continuous member.
