material 14 the slide coupler 200 consists of a coupler body 202 which is secured to one end of the compressible member 18 preferably by a locking dowel 204 or other conventional attachment means passing through the compressible member 18 seated in a recess 206 and engaging the coupler body 202 the coupler body 202 further includes a channel 208 into which the outer edge 16 of the automobile shade 12 is seated a release button 210 biased by a spring 212 is seated in a bore 214 intersecting the channel 208 the release button 210 includes a second channel 211 aligned parallel with the channel 208 and is biased by spring 212 to exert a locking pressure against the outer edge 16 securing the slide coupler 200 against sliding movement relative to the outer edge 16 when in the biased locking position a portion of the release button 210 protrudes from the bore 214 beyond the face of coupler body 202 when depressed inward towards the coupler body 202 the release button 210 compresses the spring 212 and shifts the second channel 211 into longitudinal alignment with the channel 208 when channel 208 and the second channel 211 are in longitudinal alignment the slide coupler 200 is capable of sliding movement along the outer edge 16 when released the release button 210 is biased outward from the coupler body 202 by the spring 212 moving the second channel 211 into parallel alignment with the channel 208 and trapping a portion of the outer edge 16 there between the trapped portion of the outer edge 16 resists sliding movement by the slide coupler 200.
