Collapsible Golf Club

Abstract

A collapsible golf club has three coaxially stored tapering shafts. Each of the shafts has a beveled annular ring that makes stops the extension of the shafts from the stored position to the fully extended stored position. In the fully extended position, the successive sections form interlocking or interleaved joints.

1 . A collapsible golf club shaft, comprising, 
 a. at least first, second and and third means for shaft sections with respective progressively narrowing diameters, with said first second and third means each comprising respective wide and narrow ends for nesting said first means within said second means and said second means withing said third means, in an extended coaxial relationship;    b. said first means comprising fourth means and second means comprising fifth means for forming a coextensive interleaving or interlocking joint over a coaxial length, when said first means is spatially displaced from said second means, along said axis;    c. said second means comprising sixth means and said third means comprising seventh means for forming a coextensive interleaving or interlocking joint over a coaxial length, when said second means is spatially displaced from said third means, along said axis;    d. said fifth mean in said second means comprising an annular bevel step in said narrow end of said second means and said said seventh means in said third means comprising an annular bevel step in said narrow end of said third means.    
   
   
       2 . The collapsible golf club of  claim 1 , wherein said respective means for forming a coextensive joint comprised means for forming said coextensive joint with uniform mating surfaces.  
   
   
       3 - 9 . (canceled)  
   
   
       10 . A collapsible golf club, comprising, 
 a. first, second, and third, shaft sections coaxially arranged in a spaced relationship;    b. said first, second, and third shaft sections, each having a respective tapering diameter with respective wide and narrow ends;    c. said first section comprising an an annular bevel step in said tapering diameter, displaced along said axis from said wide end of said first section;    d. said second section comprising an annular bevel step in said tapering diameter at said narrow end; and    e. said annular bevel step in said narrow end of said second section is narrower than said annular bevel step in first section.    
   
   
       11 . The collapsible golf club of  claim 10 , wherein said tapering diameter of said first section along a length of said axis between said annular bevel step and said respective wide end, is coextensive with said tapering diameter of said second section along a length of said axis starting at said narrow end; whereby displacement of said first section along said axis and in a direction to said annular bevel step in said narrow end of said second section, brings said coextensive tapering diameters into coextensive contact and an interlocking or interleaved coaxial length between said first and second sections.  
   
   
       12 . The collapsible golf club, of  claim 10 , wherein, said second section comprises an annular bevel step in said tapering diameter, displaced along said axis from said wide end of said second section; said third section comprising an annular bevel step in said tapering diameter at said narrow end of said third section; and said annular bevel step in said narrow end of said third section is narrower than said annular bevel step in first section.  
   
   
       13 . The collapsible club of  claim 12 , wherein said tapering diameter of said second section along a length of said axis between said annular bevel step and said respective wide end, is coextensive with said tapering diameter of said third section along a length of said axis starting at said narrow end; whereby a displacement of said second section along said axis and in a direction to said annular bevel step in said narrow end of said third section, brings said coextensive tapering diameters into coextensive contact and an interlocking or interleaved coaxial length between said second and third sections.  
   
   
       14 . A collapsible golf club, comprising, 
 a. first, second, and third, shaft sections coaxially arranged in a spaced relationship;    b. said first, second, and third shaft sections, each having a respective tapering diameter with respective wide and narrow ends;    c. said first section comprising an an annular bevel step in said tapering diameter, displaced along said axis from said wide end, of said first section;    d. said second section comprising an annular bevel step in said tapering diameter at said narrow end; and    e. said annular bevel step in said narrow end of said second section is narrower than said annular bevel step in first section;    f. said second section comprising an an annular bevel step in said tapering diameter, displaced along said axis from said wide end, of said second section;    g. said third section comprising an annular bevel step in said tapering diameter at said narrow end; and    h. said annular bevel step in said narrow end of said third second section is narrower than said annular bevel step in second section; and ‘wherein said tapering diameter of said first section along a length of said axis between said annular bevel step and said respective wide end, is coextensive with said tapering diameter of said second section along a length of said axis starting at said narrow end; and whereby a displacement of said first section along said axis and in a direction to said annular bevel step in said narrow end of said second section, brings said coextensive tapering diameters into coextensive contact and an interlocking or interleaved coaxial length between said first and second sections.    
   
   
       15 . The collapsible golf club, of  claim 14 , wherein said tapering diameter of said second section along a length of said axis between said annular bevel step and said respective wide end, is coextensive with said tapering diameter of said third section along a length of said axis starting at said narrow end; whereby a displacement of said second section along said axis and in a direction to said annular bevel step in said narrow end of said third section, brings said coextensive tapering diameters into coextensive contact and an interlocking or interleaved coaxial length between said second and third sections.  
   
   
       16 . (canceled)  
   
   
       17 . The collapsible golf club of  claim 14 , wherein said coextensive contact is uniform.  
   
   
       18 . (canceled)  
   
   
       19 . The collapsible golf club of  claim 1  wherein said fourth means comprises means for a narrowing annular step in said first means displaced from said wide end of said first means, whereby said fifth means narrowing annular bevel step in said second means stops said spatial extension of said first means along said axis; and wherein said sixth means comprises means for a narrowing annular bevel step in said second means displaced from said wide end of said second section whereby said seventh means narrowing annular step in said third means stops said spatial extension of said second mean along said axis.
