An aid for visual detection of a golfer's head movement, constructed of card or plastics sheet includes a black-faced sighting member that has a circular aperture there through and is hinged to a base member Adjustment of the inclination of the sighting member to the base member brings a black disc-marking line sight through the aperture. Lugs of a stay member which is hinged to the sighting member for setting the sighting-member inclination are held engaged in selected notches of the base member by a sprung-up tongue; in an alternative form of aid a stay member engages in transverse slots. Head movement is observed as apparent movement of the disc-marking within the aperture.
1. A golfing aid for assisting a golfer to detect head-movement during swing of a golf club, the golfing aid comprising:
(a) a base member having a background area and a reference marking located within the background area; and
(b) a sighting member mounted on the base member for inclination to the base member, the sighting member having an upper surface for viewing by the golfer, the upper surface including a colored region having an aperture therein, and the aperture extending through the sighting member to define a line of sight through the aperture to the reference marking within the background area of the base member;
wherein the reference making is of a first color, the colored region of the upper surface of the sighting member is of the first color, and the background area of the base member is of a second color that is visually-contrasting to the first color to enable the golfer to detect head-movement by observing apparent movement of the second color in the aperture of the sighting member.
2. The golfing aid according to claim 1 , wherein the aperture is a circular aperture in the colored region of the upper surface of the sighting member.
3. The golfing aid according to claim 1 , wherein the reference marking is a circular marking located within the background area of the base member.
4. The golfing aid according to claim 1 , wherein the first color is darker than the second color.
5. The golfing aid according to claim 1 , wherein the first color is black.
6. The golfing aid according to claim 1 , wherein the second color is white.
7. The golfing aid according to claim 1 , wherein the base member and the sighting member are each of sheet form.
8. The golfing aid according to claim 1 , including selectively-adjustable means for selective adjustment of inclination of the sighting member relative to the base member to vary inclination of the line of sight.
9. The golfing aid according to claim 8 , wherein the sighting member is hinged to the base member.
10. The golfing aid according to claim 9 , further includes a stay member hinged to the sighting member, the stay member being engageable with the base member for setting inclination of the sighting member relative to the base member, engagement of the stay member with the base member being selectively variable for varying the inclination of the sighting member relative to the base member.
11. The golfing aid according to claim 10 , wherein the stay member is selectively engageable with different ones of a series of notches in the base member for varying the inclination of the sighting member relative to the base member.
12. The golfing aid according to claim 11 , wherein the notches are a series of parallel, transverse notches of the base member, and the stay member engages selectively within one or other of these notches for setting the inclination of the sighting member relative to the base member.
13. The golfing aid according to claim 10 , wherein the base member is of elongate form, there are two series of notches spaced apart from one another transversely of the base member, the notches of each series being spaced from one another at intervals lengthwise of the base member, and the stay member has projecting lugs for engagement respectively with notches of the two series for setting the inclination of the sighting member relative to the base member.
14. A golfing for assisting a golfer to detect head-movement during swing of a golf club, the golfing aid comprising:
(a) a base member having a background area and a reference marking located within the background area; and
(b) a sighting member hinged to the base member and mounted on the base member for inclination to the base member, the sighting member having an upper surface for viewing by the golfer, the upper surface including a colored region having an aperture therein, and the aperture extending through the sighting member to define a line of sight through the aperture to the reference marking within the background area of the base member;
wherein the reference making is of a first color, the colored region of the upper surface of the sighting member is of the first color, and the background area of the base member is of a second color that is visually-contrasting to the first color to enable the golfer to detect head-movement by observing apparent movement of the second color in the aperture of the sighting member;
selectively-adjustable means for selective adjustment of inclination of the sighting member relative to the base member to vary inclination of the line of sight;
a stay member hinged to the sighting member, the stay member being engageable with the base member for setting inclination of the sighting member relative to the base member, engagement of the stay member with the base member being selectively variable for varying the inclination of the sighting member relative to the base member; and
a means for applying a resilient bias urging the stay member into engagement as aforesaid with the base member.
15. A golfing for assisting a golfer to detect head-movement while swing of a golf club, the golfing aid comprising:
(a) a base member having a background area and a reference marking located within the background area; and
(b) a sighting member mounted on the base member for inclination to the base member, the sighting member having an upper surface for viewing by the golfer, the upper surface including a colored region having an aperture therein, and the aperture extending through the sighting member to define a line of sight through the aperture to the reference marking within the background area of the base member;
wherein the reference making is of a first color, the colored region of the upper surface of the sighting member is of the first color, and the background area of the base member is of a second color that is visually-contrasting to the first color to enable the golfer to detect head-movement by observing apparent movement of the second color in the aperture of the sighting member;
a stay member hinged to the sighting member, the stay member being engageable with the base member for setting inclination of the sighting member relative to the base member, engagement of the stay member with the base member being selectively variable for varying the inclination of the sighting member relative to the base member; and
a means for applying a resilient bias urging the stay member into engagement as aforesaid with the base member.
