Abstract
Abstract A golf training aid (10') is provided and includes first and second pairs of telescopically extendable rails (16, 18, 16', 18') and a pair of adjustable slide rails (26, 30). Screws (38, 48) interconnect rails (16, 18, 16', 18') and rails (26, 30) in an operational position and folded storage position.

Claims Analysis

Claim 1
Independent Claim
418 words
A golf training aid comprising: a housing having first and second ends; first and second elongated telescopically extendable rail means each having first and second ends and being connected to said housing and being selectively extendable from said first end of said housing to an operational position or retracted to a storage position with said housing; third and fourth elongated telescopically extendable rail means each having first and second ends and being connected to said housing and being selectively extendable from said second end of said housing to an operational position or retracted to a storage position with said housing; first elongated adjustable slide rail means having first and second ends, said first end thereof being pivotally connected to said first end of said first elongated telescopically extendable rail means, said second end thereof being selectively pivotally connected to said first end of said second elongated telescopically extendable rail means in said operational position to thereby rigidly couple said first ends of said first and second elongated telescopically extendable rail means in said operational position; second elongated adjustable slide rail means having first and second ends, said first end thereof being pivotally connected to said first end of said third elongated telescopically extendable rail means, said second end thereof being selectively pivotally connected to said first end of said fourth elongated telescopically extendable rail means in said operational position to thereby rigidly couple said first ends of said third and fourth elongated telescopically extendable rail means in said operational position; said first elongated adjustable slide rail means being disposed substantially perpendicular to said first and second elongated telescopically extendable rail means to thereby maintain said first and second elongated telescopically extendable rail means in a preselected spaced apart relationship throughout the entire length of said first and second elongated telescopically extendable rail means in said operational position; said second elongated adjustable slide rail means being disposed substantially perpendicular to said third and fourth elongated telescopically extendable rail means to thereby maintain said third and fourth elongated telescopically extendable rail means in a preselected spaced apart relationship throughout the entire length of said third and fourth elongated telescopically extendable rail means in said operational position; said first and second elongated adjustable slide rail means being disposed transversely to said housing to enable the golf training aid to collapse to a compact configuration; and means for rigidly locking together said elongated telescopically extendable rail means and said elongated adjustable slide rail means in said operational position and said storage position.
Claim 2
Dependent Claim
418 words
A golf training aid comprising: a housing having first and second ends; first and second elongated telescopically extendable rail means each having first and second ends and being connected to said housing and being selectively extendable from said first end of said housing to an operational position or retracted to a storage position with said housing; third and fourth elongated telescopically extendable rail means each having first and second ends and being connected to said housing and being selectively extendable from said second end of said housing to an operational position or retracted to a storage position with said housing; first elongated adjustable slide rail means having first and second ends, said first end thereof being pivotally connected to said first end of said first elongated telescopically extendable rail means, said second end thereof being selectively pivotally connected to said first end of said second elongated telescopically extendable rail means in said operational position to thereby rigidly couple said first ends of said first and second elongated telescopically extendable rail means in said operational position; second elongated adjustable slide rail means having first and second ends, said first end thereof being pivotally connected to said first end of said third elongated telescopically extendable rail means, said second end thereof being selectively pivotally connected to said first end of said fourth elongated telescopically extendable rail means in said operational position to thereby rigidly couple said first ends of said third and fourth elongated telescopically extendable rail means in said operational position; said first elongated adjustable slide rail means being disposed substantially perpendicular to said first and second elongated telescopically extendable rail means to thereby maintain said first and second elongated telescopically extendable rail means in a preselected spaced apart relationship throughout the entire length of said first and second elongated telescopically extendable rail means in said operational position; said second elongated adjustable slide rail means being disposed substantially perpendicular to said third and fourth elongated telescopically extendable rail means to thereby maintain said third and fourth elongated telescopically extendable rail means in a preselected spaced apart relationship throughout the entire length of said third and fourth elongated telescopically extendable rail means in said operational position; said first and second elongated adjustable slide rail means being disposed transversely to said housing to enable the golf training aid to collapse to a compact configuration; and means for rigidly locking together said elongated telescopically extendable rail means and said elongated adjustable slide rail means in said operational position and said storage position.
Claim 3
Dependent Claim
49 words
The golf training aid of claim 1 and further including: means for interconnecting said second end of said first elongated adjustable slide rail means to said housing and means for interconnecting said second end of said second elongated adjustable slide rail means to said housing in said storage position.
Claim 4
Dependent Claim
66 words
The golf training aid of claim 2 wherein said first and second elongated adjustable slide rail means include slotted apertures for receiving said locking means, such that the spacing between said first and second elongated telescopically extendable rail means and the spacing between said third and fourth elongated telescopically extendable rail means is selected by varying the position of said locking means in said slotted apertures.
Claim 5
Dependent Claim
25 words
The golf training aid of claim 3 wherein said first and second elongated adjustable slide rail means includes indexing indicia disposed adjacent said slotted apertures.
Claim 6
Dependent Claim
47 words
The golf training aid of claim 1 wherein said locking means includes: boss means disposed on said first end of said first elongated telescopically extendable rail means; and said first end of said second elongated telescopically extendable rail means includes an aperture for receiving said boss means.
