Bracket for holding and clamping gas cylinder type fire extinguisher tanks

Claim 1

A bracket for securing a fire extinguisher of the type including a cylindrical tank which comprises: a one-piece molded plastic bracket having multiple generally parallel lateral ribs extending rearwards and running axialwise of the supported fire extinguisher, at least one of said ribs having holes therethrough for securing means to a support surface, the upper end of which are L-shaped in a frontwards direction and the lower end of said ribs having a seating means for resting the bottom of the fire extinguisher thereon; a first pair of parallel cross-ribs positioned at the lower end of and bridging the space between said lateral axialwise ribs and having a curved surface facedLy exposed to the lower portion of the cylindrical surface of the bottle portion of the fire extinguisher, whereupon the surface is in facewise engagement against the fire extinguisher cylinder wherein the bottle portion extends beyond the end portion of said parallel ribs; a second parallel pair of cross-ribs positioned intermediate of and bridging the space between said lateral axialwise parallel ribs and being formed, in extension therefrom, into two strap extremities starting at said outermost parallel axialwise ribs, the extremity of one strap having a hole into which the narrower extremity of the other strap having a barb is engaged by embracing the inner edge of the hole thereby imparting a tension to both said strap extensions and compression to the fire extinguisher circumscribed by said strap extremities whereupon radially directed movement of the fire extinguisher is restricted; and an annular ring clamp positioned axially in alignment with said strap extensions at the L-shaped upper end in a frontwards direction and bridging the space between said lateral axialwise ribs and having a slot opening, adapted to permit the insertion therethrough of the neck portion of the fire extinguisher, and containing a ridge projecting laterally and radially of the internal surface of said ring clamp thereby providing engagement with the groove of the neck of the fire extinguisher preventing axially directed movement of the fire extinguisher in both directions.
