  • Patent number: 8876178
    Abstract: A door handle for a sliding door having a handle and a handle base having a pair of opposed arms. The arms are provided with corresponding clips, each clip having an opening that receives a corresponding pivot pin. The handle pivots between the arms on the pivot pins. The pins are axially aligned and slidably installed in the clips for sliding motion to extend towards and retract away from each other, into and out of engagement with the handle. With the pins extended, they engage the handle, preferably with each pin engaging a corresponding insert in each end of the handle. With the pins retracted, the handle may be removed from between the arms of the handle base. The pins are preferably held in the extended position with corresponding wedges that snap into the corresponding clips behind the pins.

  • Patent number: 6207599
    Abstract: A nonwoven primary carpet backing includes thermoplastic polymer filaments or fibers bonded by means of a binder polymer. The backing includes at least a distinguishable thermoplastic woven layer, a distinguishable thermoplastic continuous layer, or a distinguishable nonwoven layer including filaments or fibers bonded by means of a binder polymer, which layer reduces the delamination strength of the backing, measured in accordance with DIN 54310, by at least 30% and preferably by at least 50%, with respect to the same backing without the distinguishable layer. Although the breaking strength of the untufted backing according to the invention is lower than that of untufted backings not including the distinguishable layer, the tufted backing according to the invention actually has a higher breaking strength and elongation than tufted backings not including the distinguishable layer.
