Tear gas spray can effectively ward off a robbery attack. However, in many cases, the great speed and the surprise employed by expert attackers allow too little time for mobilization and aiming of the canister. The present invention fits over the canister, dispensing with the cap, and supplies a guiding tunnel over the discharge button for the distal phalanx of the triggering digit. Various identifying configurations of the parts are furnished and utilized so that, by feel alone, the fitted canister, resting in the pocket or purse, may be quickly grasped, rotated, and positioned in the hand, and the triggering digit tip may be placed in the tunnel, so that the fitted canister may then be quickly brought out and used, the pointing of the digital phalanx at the assailant's face assuring that the jet reaches its mark as the discharge button is depressed.
I claim an attachment to be put on aerosol dispenser canisters of the type having a shoulder, a discharge button with a sloping top, and a crimped ferrule in between forming a neck, particularly those spraying tear gas such as Mace, comprising:
I claim the device of claim one wherein said encircling band is barely larger than said canister, and by being formed or deformed slightly out of round, fits said canister tightly enough to prevent accidental sliding and rotation, while yet allowing these motions when made intentionally;
I claim the device of claim one wherein a series of substantially rigid adapters graded as to size of tunnel groove cross-section so as to fit triggering distal phalanges of various sizes without looseness provide split-second accuracy of aiming, said adapters alike in other dimensions so that they all snap-fit into place beneath said arch, wherein four short blunt pins spaced far apart on a single level near the bottom of each of said adapters fit into four appropriately placed holes high on the limbs of said arch, and wherein each said adapter has its median region thinned and removed from said arch sufficiently that said adapter responds resiliently to distortion and permits the maneuver of snapping it into place.
I claim the device of claim one wherein said arch is so formed that said tunnel is sufficiently wedge-shaped in lengthwise section as to fit triggering distal phalanges of successively smaller sizes as the discharge button in the resting position is adjusted closer and closer to the top of said arch.
I claim the device of claim one wherein, for fitting said tunnel to various sizes of triggering distal phalanges thus assuring accuracy of aiming, said retaining ring has a plurality of threaded holes whereby it may be attached in any of a plurality of positions higher or lower on the limbs of said arch by a plurality of fitted screws each passed through a hole selected from a row of holes in said limbs, said rows matching up with said threaded holes;
I claim the device of claim one wherein said arch at one opening, when taken with the slope of said discharge button, gives ample room for entry of the triggering digit, but which, at the other opening, which is located above the jet pore, it noticeably too small for easy insertion, wrongly, of said digit;
