Telescopically adjustable game cue

A cue the length of which is continuously telescopically adjustable comprising:

• a central section;
• a butt section telescopically receiving said central section, said butt section comprising a tubular main part and a grip part threadably engaging said main part at one end of said main part and having a tubular extension extending forwardly within said main part towards an opposite end of said main part, said central section being slidably received in said tubular extension, said tubular extension having a forward end;
• and
• a lock to fix the relative axial positions of said central and butt sections by frictional engagement and comprising at least one externally bevelled collet disposed around said central section within said main part, and means co-operating with said collet such that relative rotation of said main and grip parts in one sense compresses said collet into locking frictional engagement with said central section to secure said central section relative to said butt section to fix the length of said cue, and relative rotation of said main and grip parts in an opposite sense releases said locking frictional engagement to permit relative movement of said central and butt sections to adjust the length of said cue.

A telescopic cue the length of which is infinitely adjustable between two end positions corresponding to maximum and minimum cue lengths, comprising:

• a butt section having a main part threadably engaged with a grip part;
• a central section telescopically received within said butt section for adjusting said cue length;
• and
• a lock disposed within said butt section for securing said central section relative to said butt section to fix said cue length, said lock comprising at least one externally bevelled collet disposed around said central section between first and second relatively movable abutments, and said grip part having a forward extension within said main part operable upon relative rotation of said main and grip parts in one sense to urge one of said abutments towards the other to compress said collet into locking frictional engagement with said central section to secure said central section relative to said butt section to fix said cue length, and upon relative rotation of said main and grip parts in an opposite sense to release said locking frictional engagement to permit relative movement of said central and butt sections to adjust said cue length.
