Description
- The present invention claims priority to U.S. Provisional Patent Application Ser. No. 60/763,233, filed Jan. 30, 2006, the entire disclosure of which is herein incorporated by reference in its entirety.
- The present invention relates to instruments for achieving improved accuracy in targeting objects from a distance. In particular, the present invention provides instruments designed to measure the slope of a reference point to an object at a distance. In addition, the present invention provides instruments designed to measure the cant level of a reference point to an object at a distance.
- Accurately targeting an object with a weapon (e.g., rifle) requires keen perception and skill. For long-range targets, the use of a scope with the weapon greatly enhances a user's precision. However, the use of scopes does not correct for all limitations. For example, a user must account for cant level errors, and a user must account for slope and cosine measurements. What is needed are improved devices for obtaining enhanced accuracy with a weapon (e.g., rifle).
- The present invention relates to instruments for achieving improved accuracy in targeting objects from a distance. In particular, the present invention provides instruments designed to measure the slope of a reference point to an object at a distance. In addition, the present invention provides instruments designed to measure the cant level of a reference point to an object at a distance.
- In certain embodiments, the present invention provides an angle slope level indicator (ASLI) device, comprising a housing secured with an attachment member, the housing having therein a slope indicator and a cant level indicator, wherein the cant level indicator is configured to display changes in cant level resulting from movement of the device, and wherein the slope indicator is configured to display changes in slope level resulting from movement of the device. In certain embodiments, the attachment member is configured for attachment onto a rifle scope. In certain embodiments, the cant level indicator is separated from the slope indicator.
- In certain embodiments the present invention provides a system, comprising an ASLI device rigidly attached onto a scope. In certain embodiments, the device is used with a spotting scope, rifle, telescope, artillery launcher, or any other device that launches projectiles.
- In certain embodiments, the present invention provides methods of targeting an object, comprising providing an ASLI instrument secured to a shooting device (e.g., a rifle). In some such embodiments, a user views the object through the scope, measures the slope measurement with the slope indicator, measures the cant level with the cant indicator, and adjusts the aim of the object based upon the slope measurement and the cant level measurement. In some embodiments, a ballistics calculator or computer is used to further assist in aiming.
- In certain embodiments, the present invention provides kits comprising an ASLI instrument of the present invention and a scope.

FIG. 1A andFIG. 1B show an image of an ASLI instrument embodiment of the present invention. -
FIG. 2 shows a schematic illustration of a slope gauge embodiment of the present invention. -
FIG. 3 shows an ASLI instrument rigidly attached onto a rifle scope. - The following description relates to instruments for achieving improved accuracy in targeting objects from a distance. In particular, the present invention provides instruments designed to measure the slope of a reference point to an object at a distance. In addition, the present invention provides instruments designed to measure the cant level of a reference point to an object at a distance.
FIGS. 1-3 illustrate various preferred embodiments of the instruments of the present invention. The present invention is not limited to these particular embodiments. - The angle slope level indicator (ASLI) instruments provided in the present invention are designed, for example, for a sophisticated rifleman who engages targets at high or low angles. The ASLI instruments of the present invention provide fast, precise, easy to read, vertical angle information and, in some embodiments, corresponding cosine values. In addition, the ASLI instruments of the present invention provide cant leveling for retaining a bullet's flight path in line with an optical sighting. Factoring accurate cant and slope measurements into, for example, a firing solution dramatically reduces the margin of shooting error. In some embodiments, the present invention provides an ASLI instrument capable of slope and cant level measurement combined into a single, precision-engineered, hermetically sealed unit. The ASLI instruments are not limited for use with particular devices. Indeed, the ASLI instruments of the present invention are designed for use with rifles, grenade launching devices, tanks, binoculars, telescopes, hand-guns, bows, cross-bows, etc (e.g., any device requiring improved target accuracy through obtaining cant level and/or slope measurements).
