Abstract
Abstract A viewing device to assist a golfer or the like in assessing transverse inclination of terrain along his sight line, including a base assembly adapted for attachment to a cap, hat or headpiece worn by the golfer or the like, a vertical plumb element pivoted to the base assembly about an axis parallel to the wearer's sight line of the terrain and a horizontal sighting element fixed perpendicularly along its length permitting the wearer to view seleccted terrain relative to the horizontal sighting element and rapidly assess its transverse inclination. With the base assembly secured to the bill of a cap or the like, a viewing frame surrounds the vertical plumb element and horizontal sighting element while including means for retaining both the viewing frame and vertical plumb element and horizontal sighting element out of the wearer's sight line when desired.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
155 words
A viewing device which can be optionally used by a golfer or the like for assessing transverse inclination of terrain, comprising base means for attachment to a cap, hat or headpiece worn by the golfer or other wearer, a vertical plumb element supported on the base means in front of the wearer for pivotal movement about an axis parallel to the wearer's sight line of the terrain, a horizontal sighting element afffixed to the vertical plumb element perpendicular both to the plumb element and its pivotal axis whereby the wearer may view selected terrain relative to the horizontal sighting element and rapidly assess transverse inclination of the terrain, hinge means interconnecting the base means and vertical plumb element for permitting selective movement of the vertical plumb element and horizontal sighting element out of the wearer's sight line, and retainer means for selectively maintaining the plumb element and sighting element out of the wearer's sight line.
Claim 2
Dependent Claim
155 words
A viewing device which can be optionally used by a golfer or the like for assessing transverse inclination of terrain, comprising base means for attachment to a cap, hat or headpiece worn by the golfer or other wearer, a vertical plumb element supported on the base means in front of the wearer for pivotal movement about an axis parallel to the wearer's sight line of the terrain, a horizontal sighting element afffixed to the vertical plumb element perpendicular both to the plumb element and its pivotal axis whereby the wearer may view selected terrain relative to the horizontal sighting element and rapidly assess transverse inclination of the terrain, hinge means interconnecting the base means and vertical plumb element for permitting selective movement of the vertical plumb element and horizontal sighting element out of the wearer's sight line, and retainer means for selectively maintaining the plumb element and sighting element out of the wearer's sight line.
Claim 3
Dependent Claim
35 words
The viewing device of claim 1 wherein the retainer means comprises a viewing frame surrounding the intersection of the vertical plumb element and horizontal sighting element to enhance the wearer's use of the viewing device.
Claim 4
Dependent Claim
48 words
The viewing device of claim 2 wherein the viewing frame comprises a transverse member intersecting the vertical plumb element below the horizontal sighting element so that the combined vertical plumb element and horizontal sighting element are simultaneously moved out of the wearer's sight line with the viewing frame.
Claim 5
Dependent Claim
54 words
The viewing device of claim 2 adapted for mounting on a bill of a cap, the base means being adapted for attachment to the bill of the cap, the vertical plumb element and viewing frame both being hinged to the base means generally parallel with a forward edge of the bill of the cap.
Claim 6
Dependent Claim
23 words
The viewing device of claim 3 further comprising detent means formed in the hinge joint between the viewing frame and the base means.
Claim 7
Dependent Claim
39 words
The viewing device of claim 5 wherein the detent means comprises stop means for maintaining the viewing frame and accordingly the intersected vertical plumb element and horizontal sighting element in a retracted position on the bill of the cap.
Claim 8
Dependent Claim
31 words
The viewing device of claim 6 wherein the detent means comprises additional stop means for maintaining the viewing frame in a selected viewing position with respect to the wearer's sight line.
