It is desirable in key holders of the type having a closedkey retaining loop constructionto provide somestructure which will permit the ready positioningor removal of one or more of the individual'keys without interfering with the order of the other keys in the group held on the key retaining member, and to detach whatever key without the necessity for removing a' considerable number of the keys car- 30 ried upon the key loop; and in order to provide anextremely simple device for satisfying this desired result, I have provided a key holder structure in which the key retaining loop is of a separable or split construction and formed of two hinged arm members which are so constructed and arranged that they are relatively movable to bring their'free ends into separated or into connected relation whenputting keys on and ofl' the key loop, and these free end portions of the 40 arm members are bent transversely thereof to provide inwardly extending portions so arranged that their terminal ends will be substantially aligned and conneced in the closed position of the arm members for providing the transverse hanger member on which the keys are carried; and Ihave further provided means at the end of one of the extensions of which the hanger member is formed so arranged that it will have interfitting engagement with the terminal end of the corresponding extension of the opposite arm member when in their closed position to form a closed key'loop; and I have further provided positive mechanical means in the form of a rotary member separate from the arm members of the split loop acting at the hinged ends of the same and capable of manual operation by frlctionally turning between the flesh of the thumb and. a finger of the user and rotated to cause relative rocking movement of the loop sections into a separated or into a connected position to open and close the same as desired; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous resuits may be accomplished.

With reference to the drawing, I0 designates generally the novel key holder structure and comprises a head H which may be of any desired contour and formed either of cast metal or a metal stamping. The head H is provided with an enlarged bottom portion l2 from which depends the main key carrying loop as indicated generally at l3 which in the form shown is of a split or separable construction forming a closed loop of stirrup-shaped outline, but is not limited to such contour as it may have the general form of a partial ring or comprise a member having other common geometric shapes.

As shown in Figs. 1 to 4 of the drawing, the key retaining loop I3 is made up of two sections and comprises two oppositely disposed arm members [4 and I5 which are pivotally attached at their upper ends to the lower part of the enlarged portion l2 of the head ll of the key holder at oppositely disposed positions thereof, by means of the pivot pins 16 and I! respectively, passing through suitable holes l8 and I9 formed in the respective arm members, so that the latter are relatively movable with reference to each other in the same plane so as to bring the free ends of the arm members into separated or into connected relation with each other for providing a key opening at one time and a closed key loop at another time. The arm members l4 and I5 may be formed of suitable material and be of any desired crosssectional shape, but in the present construction each is shown as being formed of solid metal of round cross-section. The arm members HI and I5 are each of substantially the same construction except at their free ends, so that it is only necessary to describe but one of such members, thus in Fig. 6, the arm member I4 is shown as having an upper portion 20 bent to present an arcuate outline curving progressively downwardly from the pivot end of the arm member to form one side wall of a stirrup-shaped key loop. The lower end of the arcuate arm portion 20 is transversely bent as indicated at 2| to provide the inwardly extending hanger portion 22, the terminal end of which is provided with a stud portion 23 which is so arranged and of such shape that it will enter and have interfitting engagement with a correspondingly shaped opening 24 formed in the terminal end face of the cooperating hanger extension 25 of the opposite arm member l5 when in the closed position of the arm members, as shown in Figs. 1 and 2.

The enlarged portion l2 of the head H is provided with a channel 26 extending lengthwise of its undersurface to receive the U-shaped ears 2! and 28 which are struck out of the flattened stock of the pivot end portions of the arms I4 and I5 respectively, as shown in Figs. 3 and 4. The head II also is provided with a central bore 30 extending axially thereof at right angles to the channel 26 and communicating therewith to form a guideway for a reciprocable screw 3| having a flanged portion 32 which is disposed withm the channel 26 and projects into the U-.

shaped cars 21 and 28 of the arm members M and I5 to have connection therewith at diametrically opposite positions of the screw 3 l. A rotary nut 33 disposed within an enlarged opening 34 formed laterally of the head! I, has screw threaded opening 35 for connection with the threads on the shank of the screw 3| and provides a means for reciprocating the screw longitudinally of the bore 39 in order to positively move the arm members I4 and I5 about their pivots simultaneously into open or into closed position.

In use, the arm members l4 and I5 normally are in closed position, as shown in Fig. 1, with one or more of the keys carried in a suspended position by the bottom cross arm of the key loop formed by connection of the respective extensions 22 and 25 of the arm members l4 and I5. When it is desired to remove a key from the key loop or to place another key thereon one simply slides the different keys which are to be retained to a location at one side of the split and then manipulates the rotary nut member 33 between his thumb and forefinger in the proper direction to force the screw 3| inwardly or downwardly of the bore 30 and consequently move the head portion 32 sufficiently to swing the arm members l4 and I5 outwardly to separate their free ends, thereby providing a space between the terminal ends through which the desired key or keys may be passed to admit them to or to withdraw them from the cross bar extensions 22 and 25 respectively. If it is desired to position a key, the procedure then is reversed, in which instance the arm members l4 and I5 are first separated to provide a key opening through which the key is passed and placed on eitherof the cross bar extensions 22 or 25, after which the rotary member 33 is manipulated as above explained but in the opposite direction to draw in the screw 3! outwardly or downwardly of the bore 30 and move the arm members [4 and I5 together with their free ends into interfitting connection to provide the closed key loop.

The member 33 operates with sufficient friction so that it will not accidentally turn or rotate when in the pocket, thus rendering it substantially impossible for the keys to be removed except by manipulation of the rotary nut. A ring 36 passed through a suitable hole 31 formed in the top end of the head H serves for attachment of the key holder to a chain, swivel hook or other suitable means, as is usual in devices of this character, for fastening the keys topart of the clothing of the user.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.
