Adjustable orientation apparatus with simultaneous adjustment of polar and declination angles

Claim 1

An adjustable orientation apparatus, comprising: first means to be oriented in accordance with a polar angle corresponding to the latitude of the geographical location of said apparatus, and a declination angle of an external object to be tracked by said apparatus; base means; second means comprising a polar axis shaft with a substantially, permanently fixed pivot casting and a first support arm, said second means orients said first means at said polar angle by said first support arm being pivotably secured to said base member at a first pivot point; said first means pivotably connected to said pivot casting at a second pivot point; third means comprising a sliding cam member and a cam plate, said cam plate secured to said first means, said cam member slidably received on said polar axis shaft at an end opposite said pivot casting, said third means orients said first means at said declination angle by pivotal movement of said first means about said second pivot point; support means pivotably secured to said base means at a third pivot point and slidably received on said polar axis shaft adjacent said cam member; manual angle adjustment means which permits adjustment of said polar angle and said declination angle by way of a single adjustment, said adjustment means interconnecting said base means and said support means; wherein, said adjustment means causes said support means to pivot about said third pivot point and to slide along said polar axis shaft, said sliding in turn causes said cam member to slide along said polar axis shaft and said cam plate causing said first means to pivot about said second pivot point, said polar axis shaft pivoting about said first pivot point.
