  • Publication number: 20170059847
    Abstract: The present invention provides an improved variable magnification device. The improved variable magnification device includes: a rotation bunch disposed around the outer side of lens barrel of a telescopic sight and moving a magnification lens mounted in the telescopic sight by turning around the outer side; a clamp unit covering the outer side of the rotation bunch and turning with the rotation bunch; and a handle disposed on the clamp unit and provided as a handle for a user to turn the rotation bunch, in which the clamp unit is detachably coupled to the rotation bunch.

  • Publication number: 20140152981
    Abstract: A lens for sighting, includes: a first lens which is inserted in a housing of a sight fixed to a gun and is disposed perpendicular to a line-of-sight of a shooter; a light emitting element which is mounted on one surface or the other surface of the first lens and emits light having a specific wavelength band; and first and second transparent wirings which are stacked on the one surface or the other surface of the first lens and supply power to the light emitting element. Dot and bow sight type sighting systems using the same are further disclosed.

  • Patent number: 8625211
    Abstract: The present invention relates to a variable magnification device and a telescopic sight using the same, and more particularly, to a variable magnification device which is capable of easily adjusting a magnification of a telescopic sight. The variable magnification device includes: a rotation bunch which has a ring shape conforming to the circumference of a barrel of a telescopic sight and includes a bent end formed on one side of the circumference of the rotation bunch; and a rod which is connected to the bent end and is bendable in the longitudinal direction of the barrel. The magnification of the telescopic sight can be adjusted with an aiming posture maintained, thereby allowing immediate hit on a target. In addition, a leverage effect can be used to easily and finely adjust the magnification of the telescopic sight with one hand, thereby preventing distortion of an aiming posture as maximally as possible.
