Description

Technological sector of invention [001] The present invention belongs to the field of weapons accessories, and refers, more specifically, to a set of sights with a stepped ramp and fiber optics, intended for sport shooting and hunting, specifically for domestically manufactured .22 caliber long guns, such as shotguns, rifles or carbines. State of the art [002] Most sight sets available on the market share a fairly similar construction, which presents significant technical challenges for shooters, especially in activities such as sport shooting and hunting. One of the main problems is related to the construction of the spring-loaded articulated ruler sight, which, although a common solution, brings with it a number of limitations that affect accuracy and usability. [003] This typical construction involves a horizontal and vertical adjustment system that operates via threaded parts lacking efficient locking mechanisms. In theory, this design should allow the shooter to make fine adjustments to the sights, adapting them to different distances and shooting conditions. However, in practice, this system proves complex and time-consuming to adjust correctly. The lack of adequate locking mechanisms means that, after adjustment, the sights remain vulnerable to unwanted displacements. Small impacts, simple handling of the weapon, or even transport can cause lateral movements in the sights, accidentally misaligning them. [004] This problem is particularly critical in the context of sport shooting, where precision is paramount. A sight that easily becomes misaligned compromises the shooter's ability to make accurate shots, which can be the difference between success and failure in competitions. Furthermore, the need to repeatedly adjust the sight to correct these misalignments makes the user experience frustrating and inefficient, distracting the shooter and increasing the time required for each shooting session. [005] The lack of robustness in the spring-loaded articulated ruler sight adjustment system not only affects accuracy but also reduces the reliability of the equipment as a whole. For the shooter, this means a constant risk of performance loss, requiring extra attention to keep the sight correctly calibrated. In a hunting scenario, for example, this failure can result in unsuccessful shots, harming the target and potentially increasing the risk of injuring the animal without properly killing it. [006] Among the main sight sets available on the market, the CZ and CBC brands stand out. The CZ sight set, manufactured in the United States, has an extremely high price due to its importation. For use on domestically manufactured weapons, adjustments with machining services are necessary. Made of steel, its articulated ruler construction includes pre-defined markings for shooting distances. Its operation is based on spring pressure, with a horizontal adjustment system via a threaded piece. However, the vertical adjustment is made by a ruler without a lock, which can easily result in accidental misadjustment. The sight point of the rear sight is very wide between the reference points of the fiber optics, and the sight point of the front sight, also in fiber optics, is very thick, which impairs the view of the target. The rear sight frequently exhibits lateral movements, as the articulated ruler construction and spring pressure do not allow lateral locking, seriously compromising the accuracy of the shots. [007] The CBC brand sight set, manufactured in Brazil, is extremely affordable, but this is due to the fact that it is made of polypropylene, which makes it very fragile. Its articulated ruler construction does not have pre-defined markings for shooting distances. Like the CZ model, its operation is based on spring pressure, with a system for adjusting shooting distances both horizontally and vertically, through two threaded keys. This makes adjustment very complex and time-consuming. In addition, the accessory does not have a locking mechanism, which facilitates accidental misadjustment. The sight point of the rear sight is very wide between the reference points of the fiber optics, and the sight point of the front sight, also in fiber optics, is very thick, making it difficult to see the target. The rear sight, similarly to the CZ model, exhibits lateral movement due to the articulated ruler construction and spring pressure, resulting in unsatisfactory shooting accuracy. [008] The predominant construction of currently available sight sets, based on spring-loaded articulated rulers without adequate locks, presents serious limitations. The complexity and time required to adjust the sight, coupled with the ease with which it can be misadjusted, represent a technical problem that directly impacts the accuracy and effectiveness of shots. More robust and reliable solutions are needed to meet the demands of shooters seeking performance and confidence in their equipment. New Invention Details [009] The new stepped ramp sig
