PATENTED 2 I975 SHEET 2 [1F 2 FIG? GARMENT HANGER ASSEMBLY BACKGROUND OF THE INVENTION Wire coat hangers are expendable items conventionally provided as a free service by dry cleaning and similar establishments. large numbers of these wire hangers are normally retained by the consumers for subsequent home and other usage. The disadvantages in the initial use of such wire hangers as well as in their subsequent home use are matters of common knowledge with perhaps the greatest disadvantage being the inherent inability of a wire coat hanger to retain a desired garment shoulder conformance. Thus a freshly pressed coat, for example, frequently exhibits creased and/or misshapen shoulders due to having been supported on a wire hanger. Other disadvantages are derived from the inherent flexibility of wire hangers which tend to be bent out of shape under any substantial clothing load, such as by a heavy topcoat for example; and the likelihood of clothing damage by contact with cracked paint or corroded portions of an older hanger. The foregoing and other inherent disadvantages have long been tolerated in the marketplace on the basis of cost. Although contoured coat hangers capable of supporting virtually any garment weight in proper shoulder conformance are readily available and in widespread usage; the cost factor, alone, dictates that their home usage cannot extend to every garment hanger employed. Such contoured hangers are conventionally made of wood to provide the required strength and may, obviously, not be regarded as expendable or giveaway items for cleaning establishments whose cleaning charges would frequently not even equal, much less defray, the cost of such hangers. Similarly, in the home, requirements in excess of hundreds of hangers for storage, guest and other uses are typical and though contoured coat hangers may be purchased for use with particular garments, the typical home user relies upon the giveaway service provided by cleaning establishments for the great majority of the required hangers.

The obvious desirability of providing an economical, shoulder conforming attachment which could be readily assembled with a wire coat hanger to convert the same into a garment hanger possessing some of the advantages of a conventional contoured hanger has long been recognized. Typical prior art approaches have employed plastic moldings conforming generally to a desired shoulder shape and adapted for interfitting engagement with a wire hanger to overlie the shoulder supporting portions thereof. The interfitting engagement is normally effected by forming'the attachment with expansible slots or friction locking detents into which portions of the wire hanger may be snapped. Exemplary are the disclosures in U. S. Pat. Nos. 2,420,ll; 2,675,948 and 3,301,447. The maintenance of the assembly is this obviously dependent upon the frictional grip imposed by plastic detents. Because of the fact that such friction locking detents are primarily designed to preclude disassembly of the parts as opposed to effecting a rigidly interrelated assembly; the "feel" ofa quality contour hanger is lacking because of the relative movement between the wire hanger and the attachment as the same is handled. A far greater disadvantage in the use of plastic, friction locking detents is that they are unable to resist substantial disassembly forces. Thus as one starts to remove a coat from such a hanger attachment, substantial separating forces are imparted which are only resisted by the necessarily small, plastic friction locking detents. The situation is aggravated by the small relative movement which is inherently permitted by hanger attachments of this type.

Notwithstanding such disadvantages from the standpoint of the home user; the test of the marketplace will depend upon acceptance by commercial users who must purchase and then supply the attachments as a free service. Because of the obvious, though modest cost increase, the commercial user must not only be satisfied that his trade will increase through the offering of such an additional service, but that his own operations will not be adversely affected by the use of the attachment. Exemplary is the typical rough handling of hangers in a cleaning establishment. Thus if an attachment tends to become separated from its wire hanger by dropping on the floor or even throwing a group of the assembled hanger attachments into a pile; then most commercial establishments would tend not to use them because of the extra time and effort required for reassembly.

It has been found that hanger attachments employing plastic, friction locking detents do not provide a sufficient gripping force on the wire hanger to preclude either small relative movement therebetween or disassembly of the same under conditions of even normal, much less rough usage.

It is the object of the present invention to provide a hanger attachment that may be firmly interlocked with a wire hanger by virtue of deflecting the wire hanger, within its elastic limits, to produce a spring restoring force coacting with a particularly configured attachment to maintain the same in firmly assembled relation. Although wire hangers have previously been bent as a deliberate incident of an assembly procedure, as in U. S. Pat. No. 2,630,254; the concept of utilizing the spring restoring force of a wire hanger to maintain a hanger attachment assembly has, apparently, not been previously recognized.

Another important feature is the fact that manufacturing tolerances are not critical in order to realize the objects of the invention.

SUMMARY OF THE INVENTION A hollow coat hanger attachment includes a hollow interior adapted to overlie the shoulders of a wire hanger. The hollow interior is configured to, in effect, create spring lever arms of both wire hanger shoulder portions. Each wire hanger shoulder portion, at opposite ends thereof, engages a fulcral surface on the attachment about which fulcral surfaces the wire shoulders are deformed, within their elastic limits, during the assembly operation. The hollow attachment interior includes a compound cam surface intermediate the fulcral surfaces which produces the deformation and against which the spring restoring force of each wire shoulder is directed. The net result of the compound cam surfaces is to bias the wire hanger upwardly and inwardly relative to the assembled. attachment. The fulcral surfaces adjacent the hook portion of the hanger preferably take the form of slots into which the collar portion of the wire hanger is fitted. A removable locking tab may then be fitted over the fulcral surfaces adjacent the hook portion to positively preclude any but a deliberate disassembly. Alternatively, or in addition, a pair of rigid stops or abutments may be formed integrally with the attachment adjacent the cam surfaces to provide a positive stop precluding disassembly.

An important feature of the invention as it relates to precluding any relative movement between the assembled parts irrespective of manufacturing tolerances is the presence of an additional pair of fulcral engagement surfaces positioned adjacent to but displaced approximately 90 from the lower fulcral engagement surfaces previously discussed. The reaction of the spring restoring forces against the compound cam surfaces thus results in seating the wire hanger firmly both upwardly and inwardly of the hollow attachment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 2 is illustrated a garment hanger assembly 10 comprising a plastic hanger attachment 12 having a hollow interior 14 adapted for interlocking assembly with a conventional wire hanger 16 in the manner generally indicated in FIG. 1. Thus, as indicated in FIG. 2, the generally straight wire hanger shoulder support arms 18 are deflected downwardly intermediate the ends thereof adjacent the position of arrows 20 by a longitudinally extending portion of a compound cam surface 22 formed integrally'with the hollow interior of the attachment 12 which cam surface 22 extends across a straight line joining the fulcral surfaces 24, 26 engaging opposite ends of each wire shoulder 18. The upper fulcral surfaces 24 associated with the collar support portion of the wire hanger and attachment take the form of downwardly inclined slots adapted to receive the shoulder portion of the wire hanger while the other of the fulcral engagement pairs simply comprise an upper, inner surface of the hollow attachment interior at the position of the arrows 27. Prior to final assembly of the parts but after insertion of wire hook 28 through a central surrounding aperture 30 in attachment 12; the parts are in the position of FIG. 1 with the lower end 32 of each wire hanger shoulder portion 18 spaced outwardly of and slightly below its associated fulcral engagement surface 26. Exertion of an upward and rearward pressure on the collar support portion 34 of wire hanger 16, to snap the same into slots 24 in the manner generally indicated by the arrows in FIG. 1, results in the concomitant deflection of a medial portion 36 of wire shoulder arms 18 due to deflecting engagement with cam surface 22 while the lower ends 32 of each wire shoulder arm come into engagement with lower fulcral engagement surfaces 26. The deflection of the wire arms 18 within their elastic limits creates an upward restoring force adjacent the mid-point of the contoured attachment shoulder supports 38 as indicated by the force vector 40 in FIG. 4. Cam surface 22 presents a compound cam surface which not only projects across a straight line joining each fulcral engagement surface pair 24, 26, as already explained, but also slopes upwardly and inwardly relative to the direction of assembly. Accordingly, the spring restoring force also exhibits a force vector 42 (FIG. 4) which is directed inwardly or away from the open side of the attachment. The hollow interior of attachment 12 is formed, in part, by a downwardly and outwardly (relative to the direction of assembly) curved lower flange 44 against which the lower ends 32 of wire shoulders 18 and/or the cross arm 46 of wire hanger 16 are biased by the inwardly directed force vectors 42.

The wire hanger is thus firmly biased upwardly into engagement with a lower interior surface of the attachment by the collar portion of the wire hanger engaging a lower wall 48 of each of the fulcral engagement surfaces or slots 24 while the lower end of each wire hanger engages a fulcral surface 26 and is biased into upward engagement therewith by force vector 40 resulting from the deformation and consequent spring restoring force of intermediate wire arm portions 36. Additionally the biasment of wire hanger 16 against flanges 44 adjacent opposite ends of cross arm 46 provides a distinct four point engagement (the cam surfaces and the flanges) between the wire hanger and attachment.

In order to effect a disassembly of the hanger assembly shown in FIG. 2 it is necessary to apply separating forces in excess of the spring biasing forces and in directions generally opposed thereto since it will be apparent that separating forces which are not directly opposed to the force vectors of FIG. 4 will require a greater magnitude to effect separation. In practice it has been found that the hanger attachment of FIG. 2 may be dropped from standing height without separation and without affecting the feel of solidarity of the assembly.

The fact that wide manufacturing tolerances are permissible while yet retaining the advantages of the invention willbe apparent from an inspection of FIGS. 4 and 5; a comparative inspection of which Figures also makes clear the longitudinally curved nature of cam surface 22. Thus, it will be seen that the wire hanger shoulder portions need not engage the attachment at an area between the lowest portion of cam surfaces 22 and the lower fulcral engagement'surfaces (FIG. 5) though it is apparent that if such engagement did take place, it would not appreciably alter the restoring forces exerted on the compound cam surfaces. Similarly, the precise degree of inward placement of the wire hanger within the hollow attachment as would be defined by the outward extent of lower flanges 44 and the depth of slots 24 is not critical since substantially the same inward force vector 42 would be exerted if the hanger were displaced in either direction from the position of FIG. 4.

It will be noted that slots 24 are formed in an integral, annular extension 50 of the hollow attachment interior which includes spaced integral stops 52 and a small recess 54 for positioning locking tab 56 (FIG. 7) in overlying relation to wire hanger collar portion 34. This assembly is shown in FIG. 6 wherein it will be appreciated that tail 58 on tab 56 is received in recess 54 and the tab bottoms in a friction fit against stops 52. This provides one additional means of insuring against inadvertent separation of the assembly which is particularly attractive because of the susceptibility of removable tab 56 to being inscribed with advertising and/or other information. Thus, the tabs could be prepared and inscribed for each individual commercial user, such as a cleaning establishment, and the same sold in bulk lots for subsequent assembly without affecting the overall standardized manufacture of the attachments shown in FIGS. 1 and 6.

A very Simple addition to the attachment of FIGS. II and 2 which may be formed integrally therewith to positively resist all but a determined effort to disassemble the parts comprises a pair of integral stops or abutments 60 which extend downwardly from upper attachment flanges 62 a distance just less than that which would result in permanent deformation of wire shoulder arms 18 during assembly. Thus, in the embodiment of FIG. 6, the assembly procedure of FIG. 1 must be accompanied by a downward, manual deflection of intermediate wire arm portions 36 to slip beneath abutment 60. It will be apparent that nothing less than a similar deflection will permit separation of the parts and, in actual use, the assembly of FIG. 6 has been thrown against walls and into piles with other hangers without separation.
