Referring now to FIGS. 6a and 7a, the operation of the garment hanger 100a of the present invention will be explained with regard to size indicator 108a. Size indicator 108a is mounted on the web 106a by sliding it over web 106a in the direction of arrow. C. While being mounted in the direction of arrow C, the pivoting latch 112 pivots in the direction of arrow A until the inwardly facing ridges 134a, 134b of finger means 134 pass over the fixed and pivoting ridges 110,112. After which, the inwardly facing fingers 134a, 134b snap into place in an area defined by the guide 136 and a bottom edge of the fixed and pivoting ridges 110,112, the area being referenced by reference numeral 152 (illustrated in FIGS. 4 and 5). As such, the size indicator 108a is releasably secured on the web 106a.

Referring now to FIGS. 6b and 7b, the operation of the garment hanger 100a of the present invention will be explained with regard to second version of the first embodiment of the size indicator 1lia. Similar to the manner in which size indicator 108a is mounted, size indicator llla is mounted on the web 106a by sliding it in the direction of arrow C over web 106b. While being mounted in the direction of arrow C, the pivoting latch 112 pivots in the direction of arrow A until the inwardly facing ridges 134a, 134b of finger means 134 pass over the fixed and pivoting ridges 110,112.

After which, the inwardly facing fingers 134a, 134b snap into place in an area defined by the guide 136 and a bottom edge of the fixed and pivoting ridges 110,112, the area being referenced by reference numeral 152 (illustrated in FIGS. 4 and 5). Simultaneously, the engagement abutments 126a and 128a touch and engage with a face of the fixed and pivoting latches, 110, 112, respectively. As such, the size indicator Illa is releasably secured on the web 106a.

To release the size indicators 108a, llla from the web 106a, a releasing force (F) is applied to the cantilevered end 122 of the pivoting latch 112, preferably by engaging. the dimple 140 thereon with a release tool (not shown). The release force (F) results in the pivoting latch 112 to pivot about the living hinge 120 in the direction of arrow A. As can be seen in FIGS. 7a. and 7b, planar side wall of the pivoting latch 112 causes the inner ridge 134a of the finger means 134 of size indicators 108a, llla to extend past the furthest extending portion of the fixed latch 110. At this point, the size indicator 108a, llla may be manually removed from the web 106a.

Preferably, the size indicators 108a, llla are fabricated from a resilient material and thereby the sides 126, 128 may be slightly biased towards each other. Thus, when the side 126 of the size indicator 108a, llla extends past the furthest extending portion of the fixed latch 110 the resilient bias of the size indicator 108a, llla pops the size indicator off of the web automatically, without further manual intervention.

Preliminary testing of the releasable size indicators 108a, llla of the present invention has indicated that a force of approximately 25-30 pounds is needed to pull the size indicators from the latches of the web. Thus, the size indicators 108a, 1'lla of the present invention are considered to be child-proof, since industry standards require a minimum force of 15 pounds to pull off a size indicator from a hanger for the size indicator to be considered child-proof.
