Variable height golf tee

Abstract

Methods and devices are provided for teeing a golf ball. A first tee has a detachably coupled post and base. The post may be a cylinder, such as a hollow cylinder, and may be made of deformable resilient material that reliably returns to a vertical position after receiving momentum originated from a golf club. The first post end includes a threaded shaft that engages with a tapped aperture of the base. The second post end presents a repeatable height from the base when the threaded shaft is fully seated into the tapped aperture. The post may be coupled with and decoupled from the base by the golfer applying manual force to alternately screw the threaded shaft into the base for coupling and then away from the base for decoupling. A plurality of posts of different lengths are provided. The base may be coupled with a mat.

What is claimed is: 
     
         1 . A golf tee comprising:
 a. A base having a planar top surface and a receiver; and   b. A post, the post having an attachment end and a top end, the top end for supporting a golf ball, and the attachment end comprising a detachable insertion feature, the detachable insertion feature for removable insertion into the base.   
     
     
         2 . The golf tee of  claim 1 , wherein the base receiver is tapped and the post detachable insertion feature is threaded for engagement with the base receiver. 
     
     
         3 . The golf tee of  claim 1 , wherein the post comprises a cylinder extending from the attachment end and comprising the top end. 
     
     
         4 . The golf tee of  claim 1 , wherein the post is flexibly resilient, whereby the post bends upon impact and returns after impact to a position for supporting a golf ball. 
     
     
         5 . The golf tee of  claim 1 , further comprising a second post, the second post having a length extending from a second post attachment end to a second post top end longer than the post. 
     
     
         6 . The golf tee of  claim 5 , further comprising a third post, the third post having a length extending from a third post attachment end to a third post top end shorter than the post. 
     
     
         7 . The golf tee of  claim 1 , wherein the base has a planar bottom surface parallel with the planar top surface. 
     
     
         8 . The golf tee of  claim 7 , wherein the top surface and the bottom surface present a height of less than 0.50 inch. 
     
     
         9 . The golf tee of  claim 1 , wherein the base presents a substantively circular cross section. 
     
     
         10 . The golf tee of  claim 1 , wherein the base comprises legs extending from the receiver, each leg having a top element disposed within the planar surface. 
     
     
         11 . The golf tee of  claim 1 , wherein the base receiver comprises a keyed ramp and the post detachable insertion feature is a keyed shaped for engagement with the keyed ramp of the base receiver. 
     
     
         12 . The golf tee of  claim 1 , wherein the receiver extends less than 0.5 inch above the base planar top surface. 
     
     
         13 . The golf tee of  claim 1 , wherein the base further comprises an anchor feature, the anchor extending from top planar surface, the anchor feature for coupling the base with a ground surface. 
     
     
         14 . A golf tee system comprising:
 a. A tapped plate;   b. A plurality of posts for supporting a golf ball above the tapped plate, each post comprising a threaded element for removable coupling with the tapped plate.   
     
     
         15 . The golf tee of  claim 14 , wherein at least one post is flexibly resilient, whereby the post bends upon impact and returns after impact to a position for supporting the golf ball. 
     
     
         16 . The golf tee of  claim 14 , wherein at least one post has a length within the range of 0.5 inch to 4.0 inches. 
     
     
         17 . The golf tee of  claim 14 , wherein at least one post further comprises a bottom shelf, the bottom shelf maintained in contact with the tapped plate when the at least one post is coupled with the tapped plate. 
     
     
         18 . A golf mat comprising:
 a. a section of durable fabric;   b. a receiver, the receiver coupled with the durable fabric and comprising a receiver attachment feature; and   c. a post for supporting a golf ball above the durable fabric, the post having a post attachment feature for detachably coupling the post with the receiver attachment feature.   
     
     
         19 . The golf mat of  claim 18 , wherein the post comprises a cylindrical body. 
     
     
         20 . The golf mat of  claim 18 , further comprising a plurality of posts of different lengths.
