Abstract

A paint dispersing training grenade includes a grenade body having dispersing passages extending between a central bore and an external surface of the grenade body, a plug threadedly received in one end of the bore, a piston resiliently urged by a spring toward the plug, a rupturable colorant containing capsule positioned between the piston and the plug, a separable release lever releasably pivotal on the grenade body and engaged with an abutment disk on a shaft extending from the piston, and an inertial delay mechanism engaged between the grenade body and the piston. The delay mechanism includes pivotable delay levers engaged with the piston at one end and having wheels rollably engaging a surface of the grenade body at another end. When the release lever is separated, movement of the piston by the spring is resisted by startup inertia of the wheels in rotating. When the inertia is overcome, the piston forceably ruptures the capsule and propels the colorant out of the grenade body through the dispersion passages.

Dependent claims

A training weapon comprising:

(a) a weapon body having a cavity therein and a plurality of dispersion passages communicating between said cavity and an external surface of said body;
(b) a rupturable colorant container positioned in said cavity, being filled with a colorant, and releasing said colorant upon being ruptured;
(c) colorant container crusher means positioned within said weapon body and being urged toward said colorant container;
(d) crusher release means engaged between said crusher means and said weapon body;
said release means normally maintaining said crusher means out of engagement with said colorant container and, upon being released, freezing said crusher means to rupture said colorant container to release said colorant and force said colorant out of said weapon body through said dispersion passages;
(e) crusher delay means engaged between said crusher means and said weapon body, said delay means preventing movement of said crusher means after release of said release means for a delay period and after said delay period allowing said crusher means to rupture said colorant container to release said colorant and force said colorant out of said weapon body through said dispersion passages;
(f) said crusher delay means including inertia delay means engaged between said crusher means and said weapon body, said inertia-delay means having a startup inertia which initially resists movement of said crusher means and which is overcome by said crusher means during said delay period;
and
(g) said inertia delay means including:
(1) a delay lever pivotally connected to said weapon body and engaged with said crusher means;
(2) a delay wheel rotatably connected to said delay lever and rollingly engaging said weapon body;
and
(3) said crusher means, when released, causing said delay lever to pivot and thereby causing said delay wheel to roll along said weapon body, rolling of said delay wheel being slowed initially by angular inertia of said delay wheel.

(b) a rupturable colorant container positioned in said cavity, being filled with a colorant, and releasing said colorant upon being ruptured;
(c) colorant container crusher means positioned within said weapon body and being urged toward said colorant container;
(d) crusher release means engaged between said crusher means and said weapon body;
said release means normally maintaining said crusher means out of engagement with said colorant container and, upon being released, freeing said crusher means to rupture said colorant container to release said colorant and force said colorant out of said weapon body through said dispersion passages;
(e) crusher delay means engaged between said crusher means and said weapon body, said delay means preventing movement of said crusher means after release of said release means for a delay period and after said delay period allowing said crusher means to rupture said colorant container to release said color ant and force said colorant out of said weapon body through said dispersion passages;
(f) said crusher delay means including inertia delay means engaged between said crusher means and said weapon body, said inertia delay means having a startup inertia which initially resists movement of said crusher means and which is overcome by said crusher means during said delay period;
and
(g) said inertia delay means including:
(1) a plurality of delay levers pivotally connected to said weapon body and engaged with said crusher means;
(2) a plurality of delay wheels rotatably connected respectively to said delay levers and rollingly engaging said weapon body;
and
(3) said crusher means, when released, causing said delay levers to pivot and thereby causing said delay wheels to roll along said weapon body, rolling of said delay wheels being slowed initially by angular inertia of said delay wheels.

A training weapon comprising:

(a) a weapon body having a central bore therethrough and a plurality of dispersion passages communicating between said bore and an external surface of said body;
(b) a plug removably positioned in said body to close one end of said bore;
(c) colorant container crusher means positioned within said bore at an opposite end of said bore from said plug, said crusher means being resiliently urged toward said plug;
(d) a rupturable colorant container positioned in said bore between said plug and said crusher means;
said container being filled with a liquid colorant and, in response to engagement by said crusher means, rupturing to release said colorant;
(e) crusher release means engaged between said crusher means and said weapon body, said release means normally maintaining said crusher means out of engagement with said colorant container;
(f) crusher delay means engaged between said crusher means and said weapon body, said delay means preventing movement of said crusher means after release of said release means for a delay period and after said delay period allowing said crusher means to rupture said colorant container to release said colorant and force said colorant out of said weapon body through said dispersion passages;
and
(g) said crusher delay means including:
(1) a delay lever pivotally connected to said weapon body and engaged with said crusher means;
(2) a delay wheel rotatably connected to said delay lever and rollingly engaging said weapon body;
and
(3) said crusher means, when released, causing said delay lever to pivot and thereby causing said delay wheel to roll along said weapon body, rolling of said delay wheel being slowed initially by angular inertia of said delay wheel.
