7 Claims. v(Cl. 70-456) This invention relates to a key case.

A main object of the present invention is to provide a new and novel key case and particularly a new and novel key case constructed so that a plurality of keys can be individually pro- .jected from the case for use by manipulation of mechanism on the key case.

A more particular object of the present invention is to provide a key case having a key case body movably receiving a key retainer which is adapted to receive and retain a key, said case having spring means for urging the key to snap outwardly to be projected from the body, and mechanism for releasably latching the key within the body responsive to movement of the key retainer from one position to another to release the key for outward movement under the influence of the spring means. i

Various other objects of the present invention will be apparent from the following description 'in Fg. 1.

` Fig. 3 is an end view of the key case disclosed .in Fig. 1.

Pig. 4 is a sectional 4-4 of Fig. 3. i

Referring to 'the accompanying drawings wherein similar reference characters designate similar parts throughout, the key case shown in the drawing includes a flat, generally rectangular body, generally indicated at 9, separable centrally into two identical parts ll and |3. The key case body can assum'e many other shapes, althoughv the' shape shown is convenient and preferable. Parts Il and l3 are secured together by any conventional means; such as machine screws |5, receivable through apertures in part I! and threadedly received by part E3.

Each part of'the body has two key-receiving recesses fo'rmed therein, one of the recesses being shown 'for' part Il in Figs. 2 and 3 and being given reference numeral il, whereas both of the recesses arershown for part |3 in Fig. 4 and being Vgiven the reference numeral 19. 'The recesses of each part are reversely disposed with respect to one anothr, as is lclearly apparent fromrFig. 4iin case of recesses [9 for body part -View taken along line i !3,'and each recess is adapted't'c receive one key. Recesses ll and l9 are formed to leave lands or raised portions 2| for part ll, and 23 for part [3 which are disposed in engagement with one another, when the parts are assembled, as is clearly apparent from Figs. 2 and 3. A1- though parts II and |2 are of identical conlstruction except for the threaded holes for receiving machine screws |5, it is apparent that when the parts are assembled, the raised portions 2| and 23 Will not be in symmetrical engagement but in non-symmetrical engagement because of the face-to-face engagement of the body parts II and |I3. By this non-symmetrical engagement, lands 2| and 23 serve to retain the keys within their respective recesses by engagement with the heads of the keys as is apparent from the phantom lines of land 2| shown in Fig. 4.

There are four key retainers 25 assuming the form of separable threaded grommet units respectively disposed in and slidable along four pairs of aligned slots 21 formed in the case body 9. The slots are arranged to' converge generally centrally of the body so that When the key retainers are moved to their inwardmost positions, the keys, generally entitled A in the figures, are carried therewith and are completely disposed within the confines of the case. However, when any key retainer is moved to its outermost position, the key stem and a minor portion of the key head of the key carried by the retainer are projected from the key case to enable the ready insertion thereof into a key hole.

Each of the separable threaded grommet units includes a grommet nut 29 and a machine screw 3| (compare Figs. 2 and 4).

Formed on body parts II and |3 are four key retaining` lugs 33, each being associated with the horizontally remote key retainer opposite it. Each retaining lug is spaced from its associated or corresponding key retainer a distance such that when a key retainer is disposed in the outer `portion of its slots, a key thereon may be pivoted into the case past the associated lug, but as .the key retainer is slipped or moved inwardly lretained within its body part by fitting intermedilate its ends within a narrow passageway formed 'across the raised portion of the associated body part, as is clearly apparent in Fig. 4 in the case of strip spring 35. The ends of the strip springs are disposed behind the lugs 33 in yielding engagement with the lugs. When a key is snapped into the key case, the associated spring end is further deformed from its normal position tov be effective to quickly urge the associated key to snap outwardly of the key case when the key retainer carrying the key is moved outwardly in its slots.

The strip springs are arranged, as shown in Fig. 4, so that when a key is disposed Within the key case, the associated spring end applies a force to the key at a point generally opposite the associated lug, urging the key into engagement with the lug to set up a frictional force serving to frictionally retain the key within. the key case. When it is desired to withdraw a' selected key for use, the key retainer carrying the same is moved outwardly in its slots to clear the key of the associated locking lug, and the key, under the infiuence of the associated strip spring, will snap outwardly and be projected from the key case, as is shown in the case of the upper key in Fig. 4.

By the present invention a novel key case has been provided which is simple in construction, easy and inexpensive to manufacture and which, While containing a plurality of keys, is so constructed that upon simple manipulation of a selected key retainer, a selected key can be individually and separately projected from the key case for instant use. The projected key can then be readily snapped back into the key case by an inward pivoting movement and then inward 'shifting movement of key retainer on which the key is mounted.

While I have shown the preferred form of my invention, it is to be understood that various changes may be made in its construction by those skilled in the art Without departing from the spirit of the invention, as defined in the appended claims.

Having thus described my invention, What I claim and desire to secure by Letters Patent is:

l. A key case, comprising a key case body, a key retainer on the body for receiving and retaining a key, movable relative to the body from one position to another, said body having a stop member formed thereon engageable with the key when said key retainer is in said one position to latch the key Within the body and disengageable with the key to release the same When the key retainer is moved to said another position, and a strip spring mounted in the body having a free end disposed in yielding engagement With the stop member When the key is projected from the body to be limited in its outward movement and operable when the key is pivoted into the body to urge the key outwardly of the key case body.
