14 Claims.

This invention relates to improvements in key sheaths.

It is the primary object of the invention to provide a novel and improved sheath for keys which is so organized that any one of a plurality of keys may be selectively advanced to position for use without requiring manipulation of buttons, snaps or other fastening means. y

Other objects of the invention have reference to a. novel and improved assembly by which manufacture of a key containing sheath is facilitated; and the provision of means for tangibly identifying to the touch of the operator the respective keys contained in the sheath; to provide a novel and improved arrangement for positioning the individual keys and providing for their manipulation; and to facilitate the insertion and removal of keys while avoiding accidental loss.

In the drawing:

Figure 1 is a perspective view of a key sheath showing one face thereof exposed and one key projected to position for use.

Figure 2 is a similar view showing the upper face of the device with both keys retracted.

Figure 3 is an enlarged detail view in longitudinal axial section.

Figure e is a detail view in enlarged transverse section taken in the plane indicated at /i-fi in Fig. 3.

Like parts are identified by the same reference characters throughout the several views.

Except for the retaining and manipulating pins which hold the `keys the entire device comprises a single piece of sheet metal out and 35 formed in reverse convolutions to provide a number of separate compartments corresponding to the number of keysv to be sheathed. For purposes of illustration I have shown only two such compartments.

One end of the strip of metal used in making up the device comprises a face plate 5 which is preferably arcuately rounded at its ends and joined by an integral connecting link 6 with an intermediate plate 7 corresponding in outline to the face plate 5. An integral hinge element 8 folded flat upon itself connects a second interfmediate plate 9 with intermediate plate '7, the two plates being in face contact. Except for convenience in manufacture the plates 7 and 9 might be integral. They may be so considered for many aspects of the present invention.

Intermediate plate 9 .is connected by an integral link member 10 with another face plate 11. The face plates 5 and 11 are tangibly differentiated 55 to the touch of the operator by means of a longitudinal rib 12 on face plate 11 and a transverse rib 13 on face plate 5. l

At one side of the device the connecting link elements 6 and 10 space the respective face plate 50 from the intermediate face plates 'Z and 9. At the ne. am zz other side of the device the face plates are provided with integral spacing lingers 14 and 15 which contact the hinge element 8, as clearly shown in Figures 2 and 4. The assembled rela.- tion ofthe parts is maintained by a. retaining tongue 16 connected integrally lto face plate 11 and upset at 17 about face plate 5, as clearly shown in Figures 1 and lThe compartments 20 and 21 are made to receive keys 22 of the ordinary ilat type used in tumbler locks. Each of lthe face plates has a'. longitudinally extending slot 24 of which the margins are-preferably flanged inwardly at 25, as shown in Figure e. Opposite ends of the respective slots communicate respectively With the 75 openings 26 of increased diameter suicient to permit insertion of the trunnion members 2'? 'which retain and facilitate manipulation of the several keys by engagement in the apertures of the handles thereof. A reduced extremity 29 on each trunnion member projects through slots 25 and is capable of sliding longitudinally in the slot to serve as a handle by means of which the operator can advance or retract the key within its compartment.

A concave depression 30 is formed in the bottom of each of the trunnion members 27, and bosses 3l of limited height are complementary to depressions 3@ to denne the extreme normal advance or retracted position of the trunnion and its associated key. e supplemental bosses 32 which register with opening 26 are larger and the trunnions can only with dimculty be forced upon these bosses. The opposition of bosses 32 to trunnion movement prevents the trunnion from accidentally moving into registry with openings 26 through which alone they are withdrawable for the insertion or removal of a key.

A device made in accordance with this inveny tion constitutes simple and compact means for sheathing two keys such, for example, as are required for an automobile and a garage door. By noting the relation oi each key to the tangibly designated face plate which covers it the operator is able, even in the dark, to select and instantly project, by means of handle 2a, the key desired for any given purpose. When the key has performed its function it may be speedily retracted and will be held in retracted position by the interaction of the detent bosses 31 with the trunnion by which the key is retained. Thus the device makes buttons and snaps unnecessary to the manipulation of the key and, with only three component parts, it provides for the storage of two separate keys.

I claim:

1. A sheath for keys comprising an open ended receptacle in which a key is longitudinally reciprocable between retracted and extended posiwill tions. a detent means for impositively deilning no the key reciprocable beneathy said slot, and a handle of less diameter than the trunnion projecting therefrom through the slot and adapted to facilitate manipulation of the trunnion, said slot having an enlargement beyond the normal range of reeiprocation of the trunnion through which ,the trunnion is removable.

3. A sheath for keys comprising an open ended receptacle having a slotted wall, a trunnion receivable through the opening in the handle of the key receprocable beneath said slot, and a handle of less diameter than the trunnion projecting therefrom through the slot and adapted to facilitate manipulation of the trunnion, said slot having an enlargement beyond the normal range of reciprocation of the trunnion through which the trunnion is removable, and detent means normally acting to restrain said trunnion from movement to a position in which it registers with the enlargement.

4. A sheath for keys comprising an open ended receptacle having a slotted wall, a trunnion reciprocable in said receptacle beneath the slot of said wall and provided with a handle projecting therethrough, and provided with a recess in its bottom, the Wall of said receptacle opposing said slotted Wall having a boss adapted in one trunnion position tointeract with the recess therein, whereby to provide an impositive detent dening said position.

5. A sheath for keys comprising an open ended receptacle having a slotted wall, a trunnion reciprocable in said receptacle beneath the slot of said wall, and provided with a recess in its bottom, the wall of said receptacle opposing said slotted wall having a boss adapted in one trunnion posistion to interact with the recess therein, whereby to provide an impositive detent defining said position, and another boss in said opposite wall presenting a greater obstacle to movement of said trunnion into registry therewith, the slotted wall of said receptacle having an opening opposite said last mentioned boss of sufficient diameter to permit the passage of said trunnion through said wall.
