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.

Henry [57] ABSTRACT A magnetic closure for keycases, pocketbooks, walv 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.
3 Claims, 6 Drawing Figures BACKGROUND OF THE INVENTION 1. Field of the Invention Closures for pocketbooks, keycases, wallets and the like. Magnetic closures for keycases.
2. Description of the Prior Art Broadly the use of magnetic material or magnets for closures is old. Specifically magnets have been used as closures for pocketbooks as shown by US. Pat. No. 2,327,532 but such magnets are fixed and provide only limited magnetic attraction for holding the pocketbook closed and such magnetic force must be small enough to be overcome easily by hand. Such arrangements do not provide any motion of one magnet to assist in closing or opening and merely provide an arrangement of opposite magnet poles to hold the device closed and manual force necessary to pull them apart.
SUMMARY OF THE INVENTION which must be overcome by manual force to pull the keycase or pocketbook apart, the present arrangement movable magnet is moved manually a small amount which causes the opposite poles to separate and like poles to come into proximity thereby opening the latch or closure. A stronger magnetic attraction may be provided in closed position since shifting of the magnet will overcome this attraction without a lot of manual force from the fingers. Keys may be mounted on a flexible cord in fixed rigid loops.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. I is a perspective view of a typical keycase with the present magnetic closure thereon and in open position.
FIG. 2 is a front elevation view of the loop arrangement in FIG. 1.
FIG. 3 is a top plan view of the loop arrangement in FIG. I.
FIG. 4 is a cross-sectional view taken along lines 44 in FIG. I with parts removed.
FIG. 5 is a cross-sectional view taken along lines 55 in FIG. 1 with parts removed.
FIG. 6 is a perspective view of a detail of the latch.
DESCRIPTION OF THE PREFERRED EMBODIMENT A typical keycase is designated by reference number 10 in FIG. I and comprises two panels 12, and 1.4 which for sake of description may be considered as the stationary panel 12 which holds the keys in the hand and movable panel 14 which moves out of the way to expose the keys for use. Panels 12 and 14 are mounted together by means of a hinge 16 of conventional construction comprising a fixed plate 18,attached by glue or otherwise to panel 14, a fixed plate 20 attached by glue or otherwise to panel 12, and a pivot pin 22 through matching, alternate hinge loops 24.
28 and provided with openings 30. The bent, looped wire 32 shown in FIGS. 2 and 3 is inserted through openings 30 by extending each loop 34 through a respective hole 30 and then the material of edge 28 is turned against the wire 32 to hold it in place. A flexible cable of nylon, plastic, wire and the like 36 is looped through each loop 34 and has its ends fixed in the matepole and it is glued or otherwise secured in place on panel 14 opposite the magnet 50 in panel 12 when the panels are closed against each other. However, latch member 42 moves slightly in its slot to bring the South pole of its magnet 50 against the North pole of magnet 52 in one position (the closed, latched position) and movement'of the latch member 42 in the other direction brings the South poles of each magnet 50, 52 in close proximity initially thereby causing repulsion and opening of the panels l2, 14.
While this has been illustrated with a keycase, it may be applied to other cases such as wallets, suitcases, instrument cases and in fact any case or device which has a closure. Therefore, while I have shown and described a particular case (keycase) and a special arrangement, this is by way of illustration only and does not constitute any sort of limitation on my invention as various changes, alterations, omissions, additions, deviations, and departures may be made in the embodiment shown without avoiding the claims hereinafter.
What is claimed is:
1. 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 3 4 said case without interfering with the closing and thereby opening said closure. alignment of 531d edges agamst each Other- 2. The device in claim 1: said outside latch member c. both of said magnets havinglflorth and South poles having a finger Operated block with protrusions thereon and in closed condition said panels being thereon latched by the magnetic attractions of said opposite 5 poles being close enough to attract and said latch The devlce m Clalm Sald a panels bemg member being movable in said slot by hand to bring hmged along a slde Opposite from 531d Closuresaid like poles close enough to cause repulsion
Claims (3)
1. 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.
2. The device iN claim 1: said outside latch member having a finger operated block with protrusions thereon.
3. The device in claim 1: said case panels being hinged along a side opposite from said closure.
