US 10,605,567 B1 · Sighting device for handheld mortar system

Abstract

A sighting assembly for a mortar employed in handheld mode. The sighting assembly is attached to the discharge end of a mortar tube by a mounting collar. The collar includes first and second distance indicator dials that employ a pointer to indicate the distance a mortar projectile will travel at different mortar angles and charges. The sighting assembly further includes structure allowing a compass to be locked in a housing by a first cam lever. The entire housing pivots about a cam bolt attached to a second cam lever that can lock the housing in a position parallel to the ground at any angle the mortar is positioned. This will allow a measurement of azimuth to a target to be taken. The azimuth and distance measurements can be used to deliver a mortar projectile to the target while keeping the target in the mortarman's line of sight.

Dependent claims

A sighting system affixed to a discharge end of a mortar comprising:

a hub;
a mounting bracket assembly;
a horizontal angle indicator assembly;
a vertical angle indicator assembly adapted to flank said horizontal angle indicator assembly;
wherein a horizontal angle indicator is received in a housing, said housing includes a cam lever securing mechanism attached to a clamping plate, such that when said cam lever securing mechanism is activated, said clamping plate moves and secures said horizontal angle indicator intermediate to said clamping plate and a linear sidewalk;
wherein said housing includes an integral depending hub bracket comprised of a first element and a second element, said first element and said second element each include an aperture, said apertures are further co-linear and are secured to a raised hub portion which includes a horizontal aperture there through;
and
wherein a hub cam lever is connected to a cam bolt which passes through said first element aperture, said horizontal aperture, and said second element aperture, allowing said housing to pivot about said cam bolt, and further permitting said housing to be locked in position by engaging said hub cam lever.

A sight for a mortar to be fired in hand held firing mode comprising:

a collar which is attached proximal to the discharge end of the mortar, said collar including:
a U-shaped hub, said U-shaped hub attached to a top side of said collar, said U-shaped hub having a central raised portion with an aperture there through, said U-shaped hub further includes a first indent on a first outer side and a second indent on a second outer side;
a housing with an extended bracket, said extended bracket connected to said central raised portion by a hinge bolt attached to a first cam lever;
a charge one dial having a first dovetail and a charge zero dial having a second dovetail;
and
whereby said charge one dial said first dovetail engages said first indent and said charge zero dial said second dovetail engages said second indent, and said housing can pivot about said hinge bolt when said first cam lever is released and said housing is locked in place when said first cam lever is secured.
