BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a resilient plastic hanger with some incorporated interlocking cam clips having a strong gripping force.
2. Description of the Prior Art
U.S. Pat. No. 5,400,932 issued to Joseph C. Hollis on Mar. 28, 1995 disclosed a hanger with gripping clips. The user of this hanger has to apply a bigger force than the clamping force to open the clip.
U.S. Pat. No. 6,389,657 issued to William Joseph Hunt on Aug. 19, 1997 disclosed a clip with a locking mechanism. The user of this clip has to apply a bigger force than the clamping force to close the jaws, because the area for pressing force is between the jaws and the pivot.
U.S. Pat. No. 5,890,634 issued to Andrew M. Zuckerman on Apr. 6, 1999 disclosed a hanger with two end latching means. This hanger has many parts to be assembled.
BRIEF SUMMARY OF THE INVENTION
The present invention discloses a resilient plastic hanger using some incorporated interlocking cam clips to grip some garments. Pushing the cam through the gap between one ends of the clip's arms, generates a clamping force to the other ends of the clip's arms, because the clip's arms are hinged together at about their middles. The generated clamping force is strong enough to keep heavy garments from falling during transportation.
Because the clip using a cam to generate the clamping force, the user of this clip can open and close the latches with a lesser force than the clamping force.

DETAILED DESCRIPTION OF THE INVENTION
In FIG. 6, the hanger has a hanging hook 2, two extentions 3 and 4, two clips 5 and 6, two cams 7 and 8.
In FIG. 7, the cam has two concentric cylindrical axles 9 and 10. One arm of the clip has two cantilevers 11 and 12 with two concentric holes 13 and 14. By inserting respectively, the axles 9, 10 into the holes 13, 14, the cam can only rotate around the center line of the holes 13, 14.
In FIG. 12 the clip has two arms 15 and 16, a hinge bar 17, two jaws 18 and 19, a latch 20. The cam has a pushing surface 21, a latch receptacle 22, a closing surface 23.
In FIG. 13, the cam has an opening surface 24.
in FIG. 12, by pressing the clip at direction A-A, the gap between the two jaws 18 and 19 is more wide. The insertion of garment into the gap at direction B is easier. Once the garment is between the two jaws 18 and 19, by pressing the clip at direction C-C, the space between the latch 20 and the cam's axles is opened more. A torque applied in direction D on the closing surface 23 of the cam, rotates the cam around its axles. Under the torque, the surface 21 pushes the latch 20 away from the cam's axles, the cam continues to rotate until the latch 20 goes into the latch receptacle 22. Now the cam is locked by the latch 20 and the latch receptacle 22.
In FIG. 12, when the pushing surface 21 of the cam pushes away the latch 20, and with the hinge 17, the cam generates a strong clamping force onto the jaws 18 and 19.
In FIG. 13, a force applied in direction E onto the cam at opening surface 24, releases the latch 20 from the latch receptacle 22. The jaws 18 and 19 are opened by the resilient hinge 17, to the initial free state. The garment can be moved away from the hanger.
