Patented July 11, 195) KEYHOLDERI $1 This invention relates to certain newand use- I ful' improvements in 'containersfor keys, and particularly 'relates to a new and improved key container which-is adapted to effect ejection of the'key'from a look when locking has been accomplished. 1 M

The-present application is a continuation in part "of our co-pending application, Serial No. 756,576. j- 1 Th'ere have been previous attempts to provide key containers which-include automatic ejection means, butthese previous attempts'have been presently"characterized by their inflexibility in use preventing their satisfactory employment alternatively with keysof varying sizes and 1 lengths. y

The principal object ofthisin'vention isto provide a key holding container" which includes means for ejecting the keyfrom a lockedlock and which is adjustable to accommodate keys of various sizes and length i A further object of the invention is to provide such a key holder with a removably fixed abutment for engaging the handle'end'of a key.

. A further object of the invention'is to provide a compact, substantially flat container of the character described r I And a further object of the invention is to generallyr improve the design, construction and utility of key ejctingholders'. .1 i

The means" by which the "foregoing" and other objects of the present inventionfare accomplished and the'manner of their accomplishment will readily beunderstood from; the' following specification upon" reference to the accompanying drawingsinwhichr *Figli 1 is a"top"*'plan View of 'the key holder of the present invention withthe top thereof removed. t I k r Fig. 2 is a similar'view with the preferred form oftop in position"and"tvith the eject'r mecha nism of the device compressed.

' 9 Claims. (olive-414') extend a minor distance inwardly" to provide for the purposes hereinplurality of longitudinallyyspaced', vertically disposed grooves which are adapted to slidably receivethe end lugs 2'! of an abutment member 29. Preferably the abutment member 29 along its forward face is provided with a shallow horizontally disposed groove (see; Fig. 3) which is adapted to engage an edge portion of the handle 3| of a conventional key 33. Atits forward end the device is provided with a box-like member whichis of rectangular cross section and is of a size to reciprocally slide'between the front wall portions 23 and between "the top 2| and the base H.- At its rearward end'the box 35 is open and is provided with laterally projecting flanges 31 which are adapted toengage the shoulder-like interiors of the front wall portions 23 to stop the forward movement of the box 35- outwardly from the base I I. At its forward end the box portion 35 is providedwith an opening 39 which is adapted to loosely surround'the shank. of a key 33. Housedwithin the box'35 is the major portion of a compression spring 4 I which spring at its rearward end isprovided with a distorted portion 43 which'is adapted-tooverliethe face of the key handle 3| and which includesa downwardly projecting, off-set hook portion which is provided to engage thestandardaperture 41 with which along the longitudinalmid line thereof to over lie a boss 5| with which Ith'e abutment member 29 is preferably provided, The channelwayfl is further preferably provided with indentations 53 which are spaced to correspond with the spacing of the vertical grooves 25 and which are adapted to. engage the boss 5! to retain the top 2 I; against undesired sliding movement.

,Insome instances it is preferable to substitute for the top 2|, which slidably engages the side walls I5, a top 12! .which is pivoted tothe side walls I5 as by a pin 123.: Preferably the top Hill is provided with a latchpin adapted'to engage a suitable slot l2! adjacent the forward edge of theside walls 15.,

determined the abutment member 29 is positioned so that its lugs 21. engage a selected pair of vertical grooves. 25, the abutment member being seated against the. base H withits grooved face forwardly,disposedt The spring 4|,maybe re-v moved fromthe spring box. 35 and the shank of p the key 33 threaded through the convolutions ammo 6f the spring with the distorted portion 43 brought into engagement with one face of the key handle 31 and the hook 45 engaged with the key aperture 47. Theed'ge' portion of the'key handle 3| may then be engaged with the groove of the forward face of the abutment member 39 and the flanges 31 seated in engagement with tl-i.

inner faces of the front wall portions 23. 'Ifhe tongues I9 of the top 2| may then be slidably engaged with the longitudinal grooves l1 and moved to position, effecting completion of the closure of the container. the channel 49 sliding along the boss 5| and the boss 5| engaging the indentation 53 which is in alinement with theagainst the front wall of the box 35 andthe rear-' ward hook and bearing against the interior of the key aperture 41. The key obviously may then be turned in the lock in usual; fashion, engagement of the key shank with the lock tumblers preventing-sliding movement ofthekey out of the lock and retainin it therein with the'box 35 and spring t l telescoped within the casing. When the key is again turned to normal unlocked position. so as to free the key from the-tumbler restra-int, the action of the spring 41 is effective to force the box 35 outwardly and tothereby effect the withdrawal or ejection of the key from the lock, thus preventing accidental presence of the key in the lock in undesired manner.

If desired the container may be provided with the pivoted top IZI. in which case the top would merely be snapped into closed position after the 7 key, spring 4|, and spring box-35 had'been positioned as previously described. It will of course beunderstood that the abutment member 29 may be permanently fixed in a single suitable posi-i tion, but it is preferred that the abutment bere'movable and adjustable to'accommodate keys of varying sizes. It will be seen thatakey 33 may be simply and readily fastened within the casing Without any change in its original shape or size and that it may as readily be removed ifdesired and another key substituted therefor.
