Abstract

This invention pertains to a device to secure a door chock to an industrial helmet. More particularly, this invention is a set of fixed and adjustable adapters with which to attach a door chock to a traditional or modern style firefighting helmet with a brim facing upward, downward, or parallel to the ground.

I claim: 
     
         1 . A device to secure a door chock to an industrial helmet comprising:
 an L-shaped body having a relatively flat planar vertical section and a relatively flat planar horizontal section;   a clamp;   an adapter;   means in which to secure said L-shaped body to said adapter;   means in which to secure said adapter to said clamp.   
     
     
         2 . The device according to  claim 1 , wherein said helmet is a traditional firefighter's helmet having an upward brim. 
     
     
         3 . The device according to  claim 2 , wherein said adapter is a fixed horizontal adapter;
 wherein said means of securing said horizontal adapter to said clamp is by screw;   wherein said means of securing said horizontal adapter to said L-shaped body is by two screws through two holes of the horizontal adapter body and two holes through the L-shaped body planar vertical section.   
     
     
         4 . The device according to  claim 1 , wherein said helmet is a modern firefighter's helmet having a downward brim. 
     
     
         5 . The device according to  claim 4 , further comprising:
 a clevis;   means in which to secure said adapter to said clevis; and   means in which to secure said clevis to said clamp.   
     
     
         6 . The device according to  claim 5 , wherein said adapter is a vertical adjustable adapter;
 wherein said means of securing said vertical adjustable adapter to said L-shaped body is by two screws through two holes of the vertical adjustable adapter body and two holes through the L-shaped body planar vertical section;   wherein said means of securing said adapter to said clevis is by a screw in an attachment hole of the vertical adjustable adapter and an attachment hole in the clevis; and   wherein said means of securing said clevis to said c clamp is by a screw through a slot in the clevis.   
     
     
         7 . The device according to  claim 5 , wherein said adapter is a horizontal adjustable adapter;
 wherein said means of securing said horizontal adjustable adapter to said L-shaped body is by two screws through two holes of the horizontal adjustable adapter body and two holes through the L-shaped body planar vertical section;   wherein said means of securing said adapter to said clevis is by a screw in an attachment hole of the horizontal adjustable adapter and an attachment hole in the clevis;   wherein said means of securing said clevis to said c clamp is by a screw through a slot in the clevis.   
     
     
         8 . The device according to  claim 5 , wherein said adapter is a universal adjustable adapter;
 wherein said means of securing said universal adjustable adapter to said L-shaped body is by two screws through two holes of the vertical adjustable adapter body and two holes through the L-shaped body planar horizontal section;   wherein said means of securing said adapter to said L-shaped body planar horizontal section is by a screw through one of three holes in the body of the universal adjustable adapter through the elongated mounting bore hole of the planar horizontal section of the L-shaped body.   wherein said means of securing said adapter to said clevis is by a screw in an attachment hole of the universal adjustable adapter and an attachment hole in the clevis; and   wherein said means of securing said clevis to said c clamp is by a screw through a slot in the clevis.   
     
     
         9 . The device according to  claim 6 , in which the adapter is secured to the clevis at such an angle that the planar vertical section of the L-shaped body is parallel or nearly parallel to the bell of the helmet. 
     
     
         10 . The device according to  claim 7 , in which the adapter is secured to the clevis at such an angle that the planar vertical section of the L-shaped body is parallel or nearly parallel to the bell of the helmet. 
     
     
         11 . The device according to  claim 8 , wherein the adapter is secured to the clevis at such an angle that the planar vertical section of the L-shaped body is parallel or nearly parallel to the bell of the helmet.
