Abstract

Abstract A magnetic closure for keycases, pocketbooks, wallets, and other containers which provides 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 magnet to assume the position of similar or dissimilar polarity. The keys are held by fixed loops and a flexible wire.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 259 words
In a magnetic closure for a case and the like, such as a keycase, wherein there is one panel which is movably attached to another panel: a. a first panel having an inwardly turned edge with a movable, outside, latch member extending through a slot in said edge and a first magnet movably mounted on and near the margin of said edge within said case to be moved by said latch member, said first magnet having an exposed magnet portion near the margin of said edge, b. a second panel having an inwardly turned edge with a fixed, second, magnet adjacent the margin of said edge thereon within said case opposite said movable magnet, said second magnet having an exposed magnet portion exposed near the margin of said edge to be affected by the exposed portion of the movable magnet when the panels are closed, said magnets being relatively movably with respect to each other with a respective panel and said respective edges of said panels engaging and abutting substantially in a line when said panels are closed and said magnets being close to each other inside said case without interfering with the closing and alignment of said edges against 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 in said slot by hand to bring said like poles close enough to cause repulsion thereby opening said closure.
Claim 2
Dependent Claim 259 words
In a magnetic closure for a case and the like, such as a keycase, wherein there is one panel which is movably attached to another panel: a. a first panel having an inwardly turned edge with a movable, outside, latch member extending through a slot in said edge and a first magnet movably mounted on and near the margin of said edge within said case to be moved by said latch member, said first magnet having an exposed magnet portion near the margin of said edge, b. a second panel having an inwardly turned edge with a fixed, second, magnet adjacent the margin of said edge thereon within said case opposite said movable magnet, said second magnet having an exposed magnet portion exposed near the margin of said edge to be affected by the exposed portion of the movable magnet when the panels are closed, said magnets being relatively movably with respect to each other with a respective panel and said respective edges of said panels engaging and abutting substantially in a line when said panels are closed and said magnets being close to each other inside said case without interfering with the closing and alignment of said edges against 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 in said slot by hand to bring said like poles close enough to cause repulsion thereby opening said closure.
Claim 3
Dependent Claim 17 words
The device iN claim 1: said outside latch member having a finger operated block with protrusions thereon.
Claim 4
Dependent Claim 17 words
The device in claim 1: said case panels being hinged along a side opposite from said closure.
