A45c 11/32 U.S. Cl. 70-457 13 Claims ABSTRACT F THE DISCLOSURE A key holder having a housing containing a spring urged reel about which a key carrying chain is Windable to retract the chain, with the keys being carried by a retaining element at the outer end of the chain and being retractable into compartments in the housing located at opposite sides of the spring containing portion of the reel.

BACKGROUND OF THE INVENTION This invention relates to key holders of the general type including a chain or other elongated flexible element which carries the keys and is windable about a reel to retract the keys when not in use.

There have in the past been devised various reel type key holders of the above mentioned general type, with the winding reel usually mounted in a housing which is connectible to the belt of a wearer. One disadvantage of these prior devices has resided in the inconvenient manner in which the carried keys dangle loosely from the reel device when in retracted condition. These dangling keys present an undesirable appearance, and further may cause wear of a persons clothing by continually rubbing against that clothing. Additionally, the exposed loosely carried keys may scratch or otherwise damage furniture, or catch on such furniture or other articles.

SUMMARY OF THE INVENTION A key carrying reel device embodying the present invention includes a housing structure within which the reel is rotatably mounted, and which forms within the housing a compartment or compartments within which the keys are at least partially receivable in the retracted condition of the chain or other flexible element. Thus, the keys are protected against contact with clothing, furniture, or the like, and are so retained as to avoid the undesirable appearance usually associated With devices of this character. Preferably, the keys are received radially between a portion of the reel which contains a retracting spring, and a peripheral Wall of the reel. The reel may have a relatively large diameter portion adjacent this spring carrying portion of the reel and forming a groove within which the chain is windable, with the keys in their retracted position being receivable axially opposite this larger diameter portion of the reel. A key retaining element carried at the outer end of the chain or other flexible element may have two oppositely projecting portions for carrying two sets of keys, with these two sets being receivable at diametrically opposite sides of the spring containing portion of the reel in their retracted positions.

`Certain additional features of the invention relate to a unique manner of attaching a group of keys to a retaining element, specifically by means of a U-shaped spring clip, having two arms which are confined with the keys between two spaced wall surfaces, with these two arms of the spring clip bearing laterally against the two wall surfaces respectively and engaging them in a relation releasably securing the clip and carried keys against detachment from the rest of the device. The interftting relation between the clip and engaged wall surfaces may be by provision of projections on one of the engaging parts received within recesses in the other engaging part.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring first to FIG. l, I have shown at 10 a key holder constructed in accordance with the invention, and adapted to be detachably carried on the belt 11 of a user. The holder includes a housing 12 containing a reel 13 mounted to turn about a horizontal axis 14 (FIGS. 2 and 3). The reel winds a flexible chain 15 which carries a key retaining element 15 to which there are connectible two sets of keys 16 and 17.

As seen best in FIG. 2, the housing 12 is formed of two front and rear sections 18 and 19 which meet each other in a vertical separation plane 20 disposed transversely of axis 14. More particularly, the forward section 18 has a vertical planar front wall 21 having the peripheral outline illustrated in FIG. la. Specifically, this front Wall, as Well as the entire housing have two spaced parallel vertical opposite side edges 22 and 23, as well as a horizontal edge 24 and horizontal top edge 25, and inclined edges 26, 27, 28, and 29. Similarly rear section 19 has a vertical planar back wall 31 spaced from and parallel to front wall 21 and having this same polygonal shape.

Extending forwardly from the rear wall 31, the rear section 19 of the housing carries an axially turned peripheral wall 30 having the vertical cross section illustrated in FIG. 3, and which, as seen clearly in FIG. 3, extends along the various edges 22, 23, 24, 26, and 27, but is interrupted at and does not extend along the upper edges 25, 28, and 29 of the housing. This peripheral Wall 30 terminates forwardly at the previously mentioned Vertical plane 20.

The front wall 21 of the housing carries a similar rearwardly directed integral peripheral wall 32 which has the same vertical cross section as wall 30 of FIG. 3, to meet that wall 30 at the vertical housing separation plane 20 in a complementary relation. As in the case of the wall 30, the wall 32 extends along the side and bottom edges of the housing, but does not extend across the top edges of the housing, corresponding to edges 25, 2S, and 29 of FIG. l. At its rear side, the vertical wall 31 of rear housing section 19 carries a spring clip 33, formed of leaf spring material secured rigidly at 34 to wall 31, and extending downwardly adjacent the wall to provide a clip which can be slipped over the belt 11 of the user to attach the device thereto.

The reel 13 may be formed of two sections 36 and 37, the former of which has an outer cylindrical surface 38 of a diameter substantially less than the minimum diameter of the peripheral housing anges or walls 30 and 32, to be spaced radially a substantial distance from those anges or walls 30 and 32, and thereby define between those walls and outer surface 38 two compartments 39 and 40 (FIG. 3), at diametrically opposite sides of the reel and of axis 14, to receive the two sets of keys 16 and 17 in their retracted positions. Radially inwardly of surface 38, section 36 of the reel contains a cylindrical rearwardly facing recess 41, defined by a cylindrical outer surface 42 and a transverse planar front wall 43, and containing a coil spring 44 for yieldingly urging the reel rotatively in a retracting direction. One end of the coil spring is secured permanently to reel section 36, as by a rivet 45, while the opposite end of the spring may extend through a slit 46 in a central boss or post 35, in a manner retaining that end against rotation. The boss 35 may be carried by and be formed integrally with front wall 21 of the housing, and be externally cylindrical and centered about axis 14.

Forwardly of the outer cylindrical surface 38 of the rear section 36 of the reel, this reel section has a radially outwardly projecting flange 47, having a planar annular surface 48 at its forward side defining one side of an annular groove 49 within which chain 15 is wound. The second section 37 of the reel may take the form of an annular disc of sheet metal having an external diameter corresponding to that of flange 47 of section 36, and rigidly secured to an axially projecting annular portion 50 of rear section 36, as by extended rivets 51.

The chain winding forward portion of the reel which forms chain receiving groove 49 is desirably confined and received rotatably within a cylindrical recess 52 formed in the rear face of forward wall 21 of the forward housing section 19. More particularly, this recess may be considered as having a cylindrical radially outer wall 53 (see FIGS. 3, 5 and 6) and a planar vertical wall 54 disposed transversely of axis 14. About recess 52, the forward wall 21 of the housing has a rearwardly facing planar surface 55 (FIGS. 3 and 5), disposed transversely of axis 14, and lying in a plane essentially flush with the rear surface of flange 47 of the reel. This surface 55 and the peripheral wall 53 of recess 52 are interrupted at the top of the housing, to form a passage 56 through which the chain extends upwardly from recess 52 for connection to key retaining element 15.

To describe the interior of the housing in different terms for clarity, it is noted that the housing has the internal cross section illustrated in FIG. 3 through the entire axial distance from rear wall 31 of the housing to the plane of surface 55, and has the cross section of FIG. 6 forwardly of surface 55 to the front of the forward disc portion 37 of the reel.

The rear housing section 19 may be secured to the forward section 18 by a screw 57 (FIG. 2) extending through the center of the rear wall 31 of the housing, and threadedly connecting into boss or post 35 of the forward housing section. Also, one of the two housing sections may have two or more locating pins `S projecting parallel to axis 14 and receivable within locating recesses formed in the other section, to prevent shifting movement of one of the sections relative to the other transversely of axis 14.

The key retaining element has a central horizontally extending portion 60 to which chain 15' is connected, as by extension of the chain through a central aperture 61 in portion 60, with an enlargement 62 on the chain being received above this aperture. Extending in two opposite directions from central portion 60, the retaining element 15 has two projections 63 and 64, to which the two sets of keys 16 and 17 respectively are connected. Each of these projections 63 and 64 desirably consists of two spaced planar vertically extending parallel arms 65 and 66, spaced essentially in correspondence with the axial width of the key receiving gap g between the upper portion of the forward surface of rear wall 31 of the housing and the upper portion of the opposed rearwardly facing surface 5S of the forward wall 21 of the housing (see top of FIG. 2). Between each of these pairs of walls 65 and 66, of the two projections 63 and 64, there is provided a key holding spring clip 67 (FIG. 4), formed of leaf spring material having the essentially U-shaped configuration of FIG. 4. More particularly, each of these clips 67 has a cross piece portion 68 which extends through the openings 69 in a series of keys 16 or 17, to hold those keys, and with the two arms 70 of the U- shaped clip projecting parallel to one another at opposite sides of the keys and spaced for reception between the two coacting side walls 65 and 66 of retaining element 15. The arms 70 of the spring clip are deformed to have small circular projections 71 receivable within correspondingly shaped circular recesses 72 formed in the walls 65 and 66, with the resilience of the spring clip urging projections 71 into interfitting engagement with recesses 72, to releasably hold the clip in its FIG. 4 position of assembled relationship between walls 65 and 66. As will be apparent, when it is desired to remove the keys, sufficient force may be exerted against them to move projections '71 out of recesses 72, and allow removal of an er1- tire group of the keys from the retaining element 15 with one of the clips 67.

To now describe the manner of use of the device, assume that the two sets of keys 16 and 17 have already been connected to key retaining element 15, at its opposite ends, by two clips of the type illustrated at 67 in FIG. 4. Also assume that the device has been mounted to the belt of a wearer as seen in FIG. 1, and that the two sets of keys 16 and 17 are nested within the two compartments 39 and 40 at opposite sides of the reel. When it is desired to then use one of the keys, the wearer merely pulls upwardly on retaining element 15 to withdraw the keys 16 and 17 from their compartments within the housing, with this withdrawing action being resisted yieldingly by the unwinding of chain 15 from reel 13 against the resistance of spring 44. The particular key which is to be used may be swung about portion 68 of the associated spring clip 47 to an outwardly projecting position in which the key may be inserted into a lock (position 16' of FIG. la). After use of the key, it and all the other keys may be returned to the downwardly projecting positions of FIGS. 1 and 3 relative to the key retaining element 15, and the latter may be allowed to retract toward housing 12 under the influence of the retracting spring 44, until the two sets of keys ultimately move downwardly at opposite sides of the reel and to the FIG. 3 position of complete retraction. In this condition, the keys are protected within the housing and are hidden from view, and the entire assembly presents an attractive overall external appearance. If it is desired to change one of the keys, or to remove a group of the keys from retaining element 15, this may be done by merely forcing a corresponding one of the clips 67 from its position of retention within element 15, as previously described, and subsequently reinserting the clip and carried keys into position within the retaining element.
