Abstract
A safety air gun may include a body, a valve, and a valve-operating lever. The body may have a shape that curves from an inlet end to an outlet end, thereby defining a convex side and a concave side. The body may define a bore that extends between the inlet end and the outlet end. The valve may so intersect the bore as to regulate flow through the bore. The valve-operating lever may be positioned on the convex side of the body and operably coupled to the valve.
Claims23
A safety air gun comprising:
- a body having a shape that curves from an inlet end to an outlet end, thereby defining a convex side and a concave side;
- a bore that is defined by the body, extends between the inlet end and the outlet end, and is formed from:
- an inlet bore segment extending from and opening at the inlet end;
- a valve bore segment having an opening to the convex side of the body and communicating with the inlet bore segment;
- an intermediate bore segment communicating with the valve bore segment and oriented at an angle such that the intermediate bore segment is accessible from the convex side through the valve bore segment opening;
- and
- an outlet bore segment communicating with the intermediate bore segment and extending from and opening at the outlet end;
- a valve so disposed in the valve bore segment as to regulate flow through the bore;
- and
- a valve-operating lever positioned on the convex side of the body and operably coupled to the valve.

A safety air gun comprising:
- a body having an inlet end oriented along an inlet axis and an outlet end oriented along an outlet axis, the inlet axis and the outlet axis defining an included angle no larger than 133 degrees;
- a bore that is defined by the body, extends between the inlet end and the outlet end, and is formed from:
- an inlet bore segment extending from and opening at the inlet end;
- a valve bore segment having an opening to a side of the body opposite the included angle and communicating with the inlet bore segment;
- an intermediate bore segment communicating with the valve bore segment and oriented at an angle such that the intermediate bore segment is accessible from the side of the body opposite the included angle through the valve bore segment opening;
- and
- an outlet bore segment communicating with the intermediate bore segment and extending from and opening at the outlet end;
- a valve so disposed in the valve bore segment as to regulate flow through the bore;
- and
- a valve-operating lever positioned on the side of the body opposite the included angle and operably coupled to the valve.

A safety air gun comprising:
- a body having an inlet end and an outlet end and defining a bore that extends between the inlet end and the outlet end, the bore formed from:
- an inlet bore segment extending from and opening at the inlet end;
- a valve bore segment having an opening to an outside surface of the body and communicating with the inlet bore segment;
- an intermediate bore segment communicating with the valve bore segment and oriented at an angle such that the intermediate bore segment is accessible from the outside surface of the body through the valve bore segment opening;
- and
- an outlet bore segment communicating with the intermediate bore segment and extending from and opening at the outlet end;
- a valve so disposed in the valve bore segment as to regulate flow through the bore;
- and
- a valve-operating lever that:
- has a first end and a second end;
- is attached to the body at an attachment position that is at or adjacent one of the first and second ends;
- curves with a constant radius of curvature between the attachment position and the more distant of the first and second ends;
- and
- is operably coupled to the valve.
