Speargun handle
View Patent ↗The invention relates to a speargun handle ( 1 ) having a reinforced trigger guard ( 5 ) which creates a chamber ( 6 ) in which there is a trigger lever ( 7 ). The handle ( 1 ) has a retaining member ( 10 ) with chambers ( 12 ) surrounded by a non-slip retaining cover ( 11 ). It also has a loading aid ( 17 ), a front end ( 23 ) for fitting a tube ( 2 ), incorporated deflectors ( 25 ) for lines and a line holder ( 32 ). The handle ( 1 ) further comprises a reverse trigger mechanism, wherein the trigger lever ( 7 ) is located outside the cartridge ( 26 ). The retaining hook ( 27 ) may alternatively have a notch for a pivot pin ( 38 ) which receives the developing stresses derived from the shaft's ( 4 ) launching.
1. A speargun handle ( 1 ), comprising:
a guard ( 5 ), which creates a chamber ( 6 ) for a trigger lever ( 7 );
a retention member ( 10 ) with chambers ( 12 ), surrounded by a non-slip retaining cover ( 11 );
a loading aid ( 17 ), with a longitudinal groove ( 18 ), positioned along a rear end of the handle;
a front end ( 23 ) to which a tube ( 2 ) is securable for launching a shaft ( 4 );
line deflectors ( 25 ) positioned along an upper part of the handle; and
a trigger mechanism secured within the handle and having a cartridge ( 26 ), a retaining hook ( 27 ), and a line holder ( 32 ) secured within the cartridge by a screw ( 39 ) through a top of the cartridge ( 26 ),
wherein the retaining hook is secured within the cartridge and longitudinally extends forward toward the front end and beyond the cartridge, and
wherein the trigger lever ( 7 ) is located outside and in front of the cartridge ( 26 ), is held on the handle ( 1 ) by a pin passing through the hole ( 34 ), and, when the shaft ( 4 ) is loaded, prevents the retaining hook ( 27 ) from freely moving.
2. The speargun handle ( 1 ) according to claim 1 , wherein the trigger lever ( 7 ) has indentations ( 36 ) up to a projection ( 40 ), terminating the retaining hook ( 27 ) to reduce a total weight thereof.
3. The speargun handle ( 1 ) according to claim 1 , wherein the chamber ( 6 ) has a groove ( 8 ) in which the trigger lever ( 7 ) and a flat base ( 9 ) move, which acts as a stop in movement of the trigger lever ( 7 ).
4. The speargun handle ( 1 ) according to claim 1 , wherein the screw ( 39 ) can be unscrewed from the top of the cartridge ( 26 ) without disassembling the trigger mechanism.
5. The speargun handle ( 1 ) according to claim 1 , wherein the cartridge ( 26 ) is provided on either side with two oval holes ( 37 ), and a pivot pin ( 38 ) is engaged between the two oval holes and the recess of the retaining hook ( 27 ) during loading to receive and distribute developing stresses during launching, of the shaft ( 4 ), on both the cartridge ( 26 ) and the retaining hook ( 27 ).
