Abstract
Abstract An elongated life line reel used by a scuba diver to contain a length of line secured at one end to the reel and at the other end to a float so that at all times the diver''s presence is known. As the diver descends the line is unwound or removed from the reel which is secured about his arm or leg by means of a pair of flexible straps respectively attached to the reel by a pair of spring members. The elongated shape of the reel allows the reel to fit securely on the forearm or leg of the diver, contain a long length of line and allow unrestricted movement of the diver in the water. The spring members function to permit easy attaching of the reel to the arm or leg and will operate to maintain the reel about the arm or leg at the different underwater pressures encounted by the diver.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
221 words
An underwater diver''s life line reel comprising: a pair of elongated flexible straps; a first rectangular elongated flat member having end edges transverse to the direction of length of said member; a second substantially rectangular elongated flat member parallel to and spaced from said first elongated member, said second elongated member having a pair of spaced apart recessed strap receiving means extending transversely to the direction of length of said member for respectively receiving said straps, said straps adapted to be secured in a spaced apart relationship around the extremity of the diver; an interconnecting substantially thin rectangular flat core member connected orthogonal to each elongated flat member for maintaining said elongated members in a parallel spaced apart relationship, said member having a length substantially less than the length of said elongated members and positioned midway between the long sides of said members and equally distant from each end of said members having the difference in length between said core and said members is substantially greater than the difference between the width of said members and the thickness of said core; and a length of line secured at one end thereof to said interconnecting core member and wound therearound, wherein said end edges of said first member cooperate with said line for preventing unintentional unwinding when said line is under tension.
Claim 2
Dependent Claim
221 words
An underwater diver''s life line reel comprising: a pair of elongated flexible straps; a first rectangular elongated flat member having end edges transverse to the direction of length of said member; a second substantially rectangular elongated flat member parallel to and spaced from said first elongated member, said second elongated member having a pair of spaced apart recessed strap receiving means extending transversely to the direction of length of said member for respectively receiving said straps, said straps adapted to be secured in a spaced apart relationship around the extremity of the diver; an interconnecting substantially thin rectangular flat core member connected orthogonal to each elongated flat member for maintaining said elongated members in a parallel spaced apart relationship, said member having a length substantially less than the length of said elongated members and positioned midway between the long sides of said members and equally distant from each end of said members having the difference in length between said core and said members is substantially greater than the difference between the width of said members and the thickness of said core; and a length of line secured at one end thereof to said interconnecting core member and wound therearound, wherein said end edges of said first member cooperate with said line for preventing unintentional unwinding when said line is under tension.
Claim 3
Dependent Claim
102 words
An underwater diver''s life line reel according to claim 1 wherein each of said flexible straps includes: a ring attached at one end, said ring adapted for receiving and passing the other end of said strap therethrough; hook means attached along the flat surface of saiD strap and adjacent the other end, and loop means attached along the same flat surface of said strap and spaced from said hook means, whereby said reel is secured about a diver''s extremity by means of said other end of said strap passed through said ring and said hook and loop means are interconnectively secured together.
Claim 4
Dependent Claim
27 words
An underwater diver''s life line reel according to claim 1 wherein each of said recessed strap receiving means is positioned adjacent the ends of said core member.
Claim 5
Dependent Claim
35 words
An underwater diver''s life line reel according to claim 3 wherein each of said recessed strap receiving means has a width and depth substantially equal to the width and thickness respectively of said strap means.
Claim 6
Dependent Claim
41 words
An underwater diver''s life line reel according to claim 1 wherein the length of said first and second elongated flat members are equal and the length of said core member is substantially one third the length of said elongated flat member.
Claim 7
Dependent Claim
29 words
An underwater diver''s life line reel according to claim 1 wherein said first and second elongated flat members and said rectangular interconnecting member are an integral unitary plastic structure.
Claim 8
Dependent Claim
19 words
An underwater diver''s life line reel according to claim 6 wherein said integral unitary plastic structure is molded nylon.
Claim 9
Dependent Claim
42 words
An underwater diver''s life line reel according to claim 1 additionally including torsion spring means respectively attached to said straps adjacent said second elongated member for receiving the free end of said strap and compressively maintaining said reel securely about the diver.
Claim 10
Dependent Claim
133 words
An underwater diver''s life line reel according to claim 8 wherein said torsion spring means comprises; a plurality of closely wound coils intermediate the ends of the spring wire, said coils having a constant internal diameter; a pair of loops for receiving said straps, said loops formed respectively by said wire ends, said loops having a long side parallel to and spaced from the axis of said coils, said loops normally in contact with each other along their long sides; U shaped means formed at the end of each of said wire ends, said U shaped means having a maximum width across the sides of said U equal to the internal diameter of said coils; and said U shaped means inserted with said coil for maintaining said loops normally in an abutting relationship.
