Scuba tank rack

A scuba rack for holding four scuba tanks with back packs and regulators attached securely in place. The scuba rack is especially suitable for securing scuba or diving tanks, with accessories attached, in an automobile, on the deck of a boat, raft or the like. A flat bottom support has four shallow cylindrical recesses in its upper surface for accommodating the bottoms of four scuba or diving tanks. The cylindrical recesses are symmetrically arranged about a rigid vertical upright post extending centrally from the bottom support. Four flexible straps are attached to the upper portion of the vertical upright and can be stretched to loop over the valve units of the respective diving tanks to force them inwardly against the vertical upright and downward securely against the bottoms of the cylindrical recesses.

I claim:

1. A portable rack for holding four cylindrical tanks securely in place, said rack comprising in combination:

(a) a bottom support means having an upper surface and a lower surface and including four retaining means in said upper surface for retaining the bottoms of said four cylindrical tanks, respectively, said four retaining means being arranged substantially symmetrically about a central portion of said upper surface of said bottom support means;

(b) upright means rigidly extending vertically from said central portion of said upper surface for laterally supporting four cylindrical tanks positioned on said bottom support means and having their bottoms respectively retained by said retaining means; and

(c) four flexible securing means engaged with said upright means for looping tautly over the necks of said four cylindrical tanks, respectively, to hold said four cylindrical tanks firmly against said upright means,

wherein each of said flexible securing means includes a flexible strand passing through an opening in said upright means, said flexible strand forming a loop, said loop having a length such that when said loop is stretched to engage the neck of one of said cylindrical tanks said loop is sufficiently taut to force said cylindrical tank securely against said upright means and wherein said loop extends both upwardly and outwardly from said opening to the neck of said cylindrical tank to produce a downward component of force on said cylindrical tank tending to force said cylindrical tank tightly against said bottom support means and a horizontal component force tending to force said cylindrical tank against said upright means.

2. The portable rack of claim 1 wherein said upright means is rigidly attached to said bottom support means.

3. The portable rack of claim 1 wherein said upright means is integral with said bottom support means.

4. The portable rack of claim 1 further including a plurality of pads attached to said lower surface.

5. The portable rack of claim 1 wherein said upright means includes means for aligned engagement of the cylindrical walls of said cylindrical tanks, such that said flexible securing means urges said cylindrical tank against said aligning means.

6. The portable rack of claim 1 wherein said bottom support means upper surface and lower surface are substantially flat.

7. The portable rack of claim 1 wherein said bottom support means and said upright means are formed from substance resistant to corrosion by salt water.

8. The portable rack of claim 1 wherein said bottom support means and said upright means are formed from wood.

9. The portable rack of claim 1 wherein said bottom support means and said upright means are formed from plastic.

10. The portable rack of claim 1 wherein said strand is flexible surgical tubing and said loop is formed by forming a knot of larger diameter than said opening at one end of said strand, said upright having an enlarged hollow space therein for concealing said knot, whereby said knot is retained within said hollow space by said opening.
