Abstract
Abstract A vertically adjustable sport trainer restrains a golfer''s head from movement until club-ball impact, sensed by an adjustable switch adjacent the ball, energizes a solenoid actuator disabling a set of engaged detents thereby permitting a head restraint mounting arm to be spring driven about a pivot pin horizontally away from a golfer.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
250 words
A golf training device for preventing rearward movement or turning of a golfer''s head until impact of a golf club with a target ball comprising an upstanding support, a vertically oriented pivot pin connected to the support near an upper portion thereof, an arm connected to the pivot pin, a head rest connected to the arm remote from the pivot pin, a torsion spring connected to the arm and to the support for moving the arm and head rest horizontally away from a first golfer''s head engaging position adjacent the rear side of a golfer''s head, opposite the intended direction of ball travel, to a second position away from a golfer''s head, first and second disengageable detents, the first detent being connected to the arm and the second detent being connected to the support, the detents being engaged when the head rest is adjacent the golfer''s head, and actuator means connected to one of the detents for disengaging the detents and permitting the spring to drive the arm to the second position, a supply line connected to the actuator, a source of power connected to the supply line and a valve in the supply line for controlling application of power from the source to the actuator, the valve having means to sense a golf club in a position normally associated with impact of a golf ball to operate the valve and to thereby operate the actuator, permitting the spring to drive the arm and head rest to the second position.
Claim 2
Dependent Claim
250 words
A golf training device for preventing rearward movement or turning of a golfer''s head until impact of a golf club with a target ball comprising an upstanding support, a vertically oriented pivot pin connected to the support near an upper portion thereof, an arm connected to the pivot pin, a head rest connected to the arm remote from the pivot pin, a torsion spring connected to the arm and to the support for moving the arm and head rest horizontally away from a first golfer''s head engaging position adjacent the rear side of a golfer''s head, opposite the intended direction of ball travel, to a second position away from a golfer''s head, first and second disengageable detents, the first detent being connected to the arm and the second detent being connected to the support, the detents being engaged when the head rest is adjacent the golfer''s head, and actuator means connected to one of the detents for disengaging the detents and permitting the spring to drive the arm to the second position, a supply line connected to the actuator, a source of power connected to the supply line and a valve in the supply line for controlling application of power from the source to the actuator, the valve having means to sense a golf club in a position normally associated with impact of a golf ball to operate the valve and to thereby operate the actuator, permitting the spring to drive the arm and head rest to the second position.
Claim 3
Dependent Claim
51 words
The device of claim 1 wherein the support comprises a support plate having an upper horizontal flange and a lower horizontal flange, wherein the pivot comprises a pivot pin vertically mounted between the upper and lower horizontal flanges, and wherein the arm comprises a cam yoke pivoted on the pivot pin.
Claim 4
Dependent Claim
36 words
The device of claim 2 wherein the first detent comprises a shoulder on the cam yoke, and wherein the second detent comprises first and second pivotally interconnected links, one of which is connected to the actuator.
Claim 5
Dependent Claim
48 words
The device of claim 3 wherein a guide is formed by an opening in one of the horizontal flanges and wherein the second detent further comprises a cam pin connected to one of the pivotally interconnected links and constrained to move in a predetermined space by the guide.
Claim 6
Dependent Claim
82 words
The device of claim 1 wherein the support comprises a wall mounting member and a second support member which is vertically adjustable along the wall mounting member, a pivot pin support extending outward from the second member, and wherein the pivot comprises a pivot pin vertically mounted in the pivot pin support, a detent pivot pin connected to the pivot pin support and wherein the second detent comprises first and second pivotally interconnected links, one of which is connected to the actuator.
