Toy hand grenade

Abstract

A toy hand grenade comprises a cardboard tube, pyrotechnic compositions including a smoke agent, an emitting charge and a color powder, a pulling thread and friction ignition means, an ignition mechanism including friction composition, ignition composition, a pulling thread, a safety fuse and a quick fuse. The quick fuse is firstly ignited by the friction between the cotton pulling thread and the friction composition. The toy hand grenade is thrown at an open space beyond 10 meters after ignition to release a great quantity of smoke and generate a great quantity of gases. The gases may destroy the structural shape of the cardboard tube and set off massive color powder. The invention is mechanically simple and inexpensive to manufacture as compared with the conventional toy hand grenade. Of course, it does not lose its effectiveness due to rusting.

We claim:  
     
         1 , A toy hand grenade, comprising 
 a cardboard tube sealed by first and second clay in both ends to form a chamber;    pyrotechnic compositions including a smoke agent, an emitting charge and a color powder being placed in the chamber of the cardboard tube;    a means for friction and ignition;    characterized in that said means for friction and ignition includes a mean for friction on which a friction composition is covered, and a means for ignition on which an ignition composition is covered, which is kept the means for friction at some distance and is above the means for friction; a quick fuse, one end of which is in contact with the friction composition and another one is connected to a pulling thread; and a safety fuse, one end of which is in contact with pyrotechnic composition and another one is in contact with the ignition composition, thereby when a pulling ring connected to the pulling thread is pulled downwardly, the means for friction is frictionally moved against one another so that the friction composition is ignited, by which the quick fuse and the safety fuse are also ignited in an orderly way, finally, pyrotechnic composition is burned upon ignition to release a great quantity of smoke.    
     
     
         2 , A toy hand grenade according to  claim 1 , wherein said friction composition consists of 30 parts by weight of potassium perchlorate, 30 parts by weight of magnalium, 20 parts by weight of sulphur and 20 parts by weight of copper oxide.  
     
     
         3 . A toy hand grenade according to  claim 1 , wherein said friction composition consists of 20 weight percent of phosphorus and 80 weight percent of potassium chlorate.  
     
     
         4 , A toy hand grenade according to  claim 1 , wherein said friction composition consists of 75 weight percent of lead oxide and 25 weight percent of silicon.  
     
     
         5 , A toy hand grenade according to  claim 1 , wherein said ignition composition consists of 75 weight percent of potassium nitrate, 10 weight percent of sulphur and 15 weight percent of carbon.
