Definitions

  • the object of the invention is a memory indicia system for forming an individual alignment range in an optical scope.
  • the object of the invention is also a method of forming an individual alignment range in an optical scope, wherein there is an alignment turret and a fixed point in relation to which the position of the alignment turret can be determined.
  • the distance of a bullet shot with a firearm in normal conditions is curved down-ward due to the influence of gravity on bullets.
  • the curve of the bullet's distance depends, in practice, on the speed, weight, and shape, etc., of the shot bullet as well as whether the firearm is shot upward or downward.
  • the most common optical scopes for firearms are adjusted such that the center of the point of aim of the optical scope and the points of impact of the shot bullet are in the same place on the target at a given distance.
  • optical scopes have their own alignments both in the horizontal and vertical directions from which the optical scope is aligned with the center of the bullets' points of impact.
  • the marksman must aim at the target upward or downward to ensure the impact is at the desired point. Estimating the magnitude to which the point of aim should be raised or lowered is difficult even though the distance has been measured or estimated correctly. It is specifically the difference between the distance of the bullet and the point of aim that determines the magnitude to which the point of aim is raised or lowered. If the shooter is not familiar with this difference or fails to consider it, then the shot bullet may miss the target completely. The possible magnitude ratio, which enlarges the target when looking through the optical scope, may make the estimation of the extent to which the point of aim should be raised or lowered more difficult.
  • Alignment is done in the ordinary way by shooting test shots in the desired distance after which the optical scope is adjusted to the proper position from the alignment turrets according to instructions. If the alignment is not made according to the cartridge to be shot, then it is possible that the bullet will completely miss the desired target.
  • EP1769213 presents an optical scope that has a memory ring(s) onto which the previous alignment can be saved.
  • the memory ring usually works reliably for only one distance, cartridge, and barrel at a time, and it can only be used for scopes designed exclusively for it. This type of memory ring cannot be used with ordinary scopes, which have not been designed for use with this memory ring.
  • U.S. Pat. No. 4,285,137 describes a distance compensating device, which includes an indicia carrying strip upon which fixed indicator marks have been made, whereby the shooter is unable to easily change the indicator marks or their location to suit his own the firearm, scope, or cartridge. Every firearm and cartridge combination possesses its own individual ballistic distance for which reason the invention described in U.S. Pat. No. 4,285,137 is not practical. It can only be used in a certain type of firearm, the ballistic speed and distance of which has been calculated beforehand. Because the afore-mentioned information is distinct and firearm-specific, it cannot be generalized that the said information would suit other firearms and scopes well.
  • the aim of the present invention is to introduce a memory indicia system for an ordinary optical scope with which a firearm and optical scope can be easily and reliably realigned to several previously aligned distances and types of cartridges without having to perform new alignment shots.
  • the object of the invention is a memory indicator system with which the shooter of a firearm can easily form an individual alignment range in an optical scope attached to a firearm.
  • the memory indicia system comprises a basic indicia indicator attached to the alignment turret of the optical scope and one or more additional indicia components attached on top of the basic indicia indicator. Both the basic indicia indicator and the additional indicia components have at least a range value, which indicates the alignment distance, and an alignment mark.
  • the range value describes the numerical value of the firearm's alignment distance, i.e. the distance from the muzzle of the barrel to the target.
  • the alignment mark is a mark which is placed at the point of a fixed or drawn mark on the saddle of the scope, when the firearm is being aligned. Using the alignment mark, the alignment turret can be precisely restored back to the point defined beforehand.
  • the basic indicia indicator and additional indicia components further have a cartridge code, descriptive of the cartridge used in alignment.
  • cartridge code descriptive of the cartridge used in alignment.
  • the range value, alignment mark and cartridge code appear as graphic notations distinct from the background of the basic indicia indicator.
  • the said graphic notations are rectangular, square, triangular or circular or a combination of these in shape.
  • the said graphic notations may also comprise numbers and/or letters.
  • the basic indicia indicator and additional indicia components are film-like components, on the one surface of which is a film adhesive covered with removable protective film. Therefore, the basic indicia indicator and the additional indicia components are ready to be attached after the protective film has been removed.
  • the basic indicia indicator and additional indicia components are layered in the rim or on top of the alignment turrets on the optical scope.
  • the basic indicia indicator and additional indicia components are made of a transparent material. This transparency allows all of the notations to be identified even if the basic indicia and additional indicia either completely or partially cover each other.
  • a separate cartridge item indicator that has the same cartridge code as on the basic indicia indicator and additional indicia components, which can be attached to the cartridge box. Thanks to the cartridge item indicator, the user of the firearm knows what cartridges have been used to align the firearm.
  • a distinct alignment range is created on the optical scope.
  • the scope should have a rotating alignment turret and the saddle should have a fixed point, the relation to which the position of the rim of the alignment turret can be determined.
  • the method involves first choosing the first distance to which the firearm is to be aligned.
  • the alignment distance can be, for example, 100 meters.
  • the firearm is aligned to the chosen distance according to the instructions of the scope's manufacturer, i.e. the scope's reticle is moved to the center of the bullets' point of impact. Alignment usually requires the elevation of the scope's reticle, which is done by turning the height alignment turret.
  • the basic indicia indicator which has at least the range value indicating the alignment distance and the alignment mark, is attached to the alignment turret on the optical scope.
  • the basic indicia indicator is attached in place such that the alignment mark on it is positioned at the fixed point on the optical scope.
  • At least one other desired distance to be aligned is subsequently chosen and the firearm is aligned at the chosen distance in the previously described way.
  • the additional indicia component which has at least the range value indicating the alignment distance and the alignment mark, is attached to the alignment turret on the optical scope. It is attached such that the alignment mark of the additional indicia component is positioned at the fixed point on the optical scope.
  • the scope has a distinct alignment range with which the shooter can quickly align the scope to the desired distance aligned beforehand.
  • basic indicia indicator and additional indicia components which also have a cartridge code describing the cartridge used in alignment, are used in the method. Thanks to the cartridge code, the user of the firearm knows immediately what cartridges have been used to align the firearm and knows how to choose the correct cartridges for shooting.
  • the basic indicia indicator and additional indicia components are layered in the rim or on top of the alignment turrets on the optical scope.
  • the basic indicia indicator and additional indicia components are film-like components which are attached in place with the film adhesive on them.
  • the memory indicia indicator can be adjusted to function on the firearm and cartridge in question at the desired distance.
  • the memory indicia indicator also makes it possible to align other suitable types of cartridges for the firearm at the same time, whereupon using another cartridge type tested beforehand does not require realignment of the optical scope; rather, the alignment can be restored to the value tested beforehand if so desired.
  • FIG. 1 illustrates the memory indicia system, according to the invention, from the isometric direction of view, attached to the rim of rotating axle of the alignment turret on the optical scope, having the markings according to the example,
  • FIG. 1 a illustrates, from the isometric direction of view, the cartridge item indicator associated with the memory indicia system of the optical scope, according to the invention attached to the cartridge box, having the markings according to the example,
  • FIG. 2 illustrates, from the isometric direction of view, the memory indicia system, according to the invention whereby the different components of the systern have been separated from each other and,
  • FIG. 2 a illustrates, from the isometric direction of view, the cartridge item indicator associated with the memory indicia system of the optical scope, according to the invention, whereby the cartridge item indicator is detached from the cartridge box.
  • the memory indicia indicator comprises a basic indicia indicator 2 and/or one or more additional indicia components 3 , 4 .
  • the indicia are attached on top of or in the rim of the alignment turrets 5 of an optical scope, such as a rifle scope 1 , to be attached to a firearm.
  • Rifle scopes are as such a well-known type of optical scope, which have two alignment turrets for aligning the scope.
  • the alignment turret on top of the rifle scope is used to move the scope's sighting point in a horizontal direction and the alignment turret on the side of the scope is used to move the scope's sighting point in a vertical direction.
  • 1 and 2 by way of example, is a rifle scope.
  • the invention is not, however, limited to be used with rifle scopes only; rather, it can be used in all optical scopes that have at least one alignment turret for moving the scope's sighting point.
  • the optical scope itself does not belong to the scope of this invention and therefore the function and structure of it will not be explained in any detail herein.
  • the film-like component of the basic indicia indicator 2 can be in the shape of a circle, rectangle, square, parallelogram, or a combination of these.
  • the base material for the basic indicia indicator can be either completely transparent or non-transparent or it may constitute of transparent and non-transparent portions.
  • the outer dimensions of the basic indicia indicator are a little smaller than the length and height of the rim of the alignment turret on the optical scope.
  • the range value 8 and the cartridge code 9 indicating the used cartridge, possibly comprising letters, numbers, symbols or a combination of these, are indicated on the basic indicia indicator clearly differentiated from the base material.
  • the markings in question may be indicated in different colors whereby they are easy to distinguish from each other. FIGS.
  • FIGS. 1 and 2 illustrate, by way of example, the distance with a numerical value of 100 and the letter X as the cartridge code.
  • the alignment mark 11 is located under or adjacent to the distance and the cartridge code on the basic indicia indicator. It may be a dot, line or other clearly distinctive geometric shape.
  • FIGS. 1 and 2 illustrate, by way of example, the alignment mark as an arrow pointing downward.
  • the distance and cartridge code as well as the alignment mark 11 may be located at different heights on the basic indicia indicator 2 . In this case, it must be ensured they are joined together with a line connecting the marks or, for example, with the same colors.
  • An indication 13 denoting the direction of alignment of the alignment turret 5 may be located on the basic indicia indicator 2 , which facilitates the alignment of the optical scope.
  • the symbol indicating the direction of alignment illustrated in FIGS. 1 and 2 is the shape of a triangle, the one tip of which indicates the direction of rotation of the alignment turret.
  • the basic indicia indicator 2 When the firearm is aligned to the distance and cartridge indicated by the distance 8 and cartridge code 9 on the basic indicia indicator 2 , according to the instructions of the manufacturer of the optical scope, the basic indicia indicator 2 is attached on top of the alignment turret of the optical scope.
  • the basic indicia indicator 2 is positioned on the rim of the alignment turret 5 such that the alignment symbol 11 is at the point of the fixed mark 6 located on the optical scope's saddle 1 .
  • the saddle of the optical scope already has a fixed mark, which helps in determining the rotating position of the alignment turrets. If the optical scope does not include a fixed mark such as this, it can be made with a marker, for example.
  • the basic indicia indicator 2 is attached on top of the alignment turrets 5 with glue.
  • the other side of the basic indicia indicator already has a transparent film adhesive on it for attaching the basic indicia indicator.
  • the film adhesive is covered with a removable protective film, which is removed just before attaching the basic indicia indicator.
  • the glue on the film adhesive is soft and sticker-like, which allows the basic indicia indicator 2 to be attached and detached many different times.
  • the memory indicia system comprises a number of additional indicia components 3 , 4 whereon the distance, cartridge code and alignment symbol are indicated with graphic symbols as with the basic indicia.
  • the additional indicia component is attached onto the alignment turret on top of the basic indicia indicator 2 or directly on the surface of the elevating alignment turret 5 .
  • the alignment symbol 11 of the additional indicia component is placed at the point of the fixed mark 6 on the optical scope's saddle 1 .
  • the material of the additional indicia components 3 , 4 is transparent enabling the previous alignment values under the additional indicia to be read even though the additional indicia may cover the basic indicia partially or completely.
  • the additional indicia components may be of equal size and/or shape as the basic indicia indicator 2 , or their size and/or shape may deviate from the basic indicia indicator.
  • the additional indicia components 3 , 4 are attached on top of the basic indicia indicator 2 or the alignment turret 5 of the optical scope using the film adhesive on the other surface of the additional indicia component.
  • the additional indicia components are thus film-like components like the basic indicia indicator with a film adhesive covered with a removable protective film ready on one side.
  • the features of the adhesive correspond to those of the adhesive on the basic indicia indicator. Alignment of the firearm can continue as described above for other desired distances as needed.

  • the firearm's alignment can be restored to the distances on the memory indicia indicator tested beforehand at a later time.
  • the alignment is restored to a certain distance by adjusting the optical scope's 1 alignment turrets such that the alignment mark 11 in the indicia corresponding to the distance 8 and the cartridge symbol 9 moves to the point of the fixed mark 6 on the optical scope's saddle 1 .
  • the symbol indicating the adjustment direction 13 assists in remembering the direction of rotation of the alignment turret.
  • the additional indicia may be located in a different order because they are transparent and therefore can be seen although they are one upon the other in different layers. When the basic indicia indicator and additional indicia components have been put in place, they form a distinctive alignment range in the optical scope.
