Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C. § 119 (e) to U.S. Provisional Patent Application Ser. No. 62/827,732, filed on Apr. 1, 2019, the entire contents of which are hereby incorporated by reference.

FIELD OF THE INVENTION

The present invention relates to a detachable sight and more particularly to a detachable sight with control logic of the light thereon.

BACKGROUND OF THE INVENTION

Laser sights are particularly effective as sighting devices because the lasers illuminate spots on their targets and do not require users to align an eye with a sighting device, which can limit or obscure the user's view of the targets or their surroundings. When mounted on firearms, the laser sights emit beams that are directed along the expected flight paths of projectiles discharged from the firearms. Usually the laser beam is triggered to turn on when the user pushes or touches the on button. In the present invention, with a different control logic, the laser beam can be triggered to “turn off” when the user touches the sensor on the sight.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a detachable sight with a switch with a momentary sensor for a firearm.
It is another object of the present invention to provide a detachable sight with a momentary sensor that can be used to shut off the laser beam of the sight when the user's finger blocks the momentary sensor.
In one aspect, a sight with a switch to control a laser beam thereon may include a main body, a switch with a momentary sensor, a laser sight, a plurality of locking screws to lock the sight onto a firearm, a laser adjustment screw, and a charging socket. In one embodiment, the laser of the laser sight is tactical low-profile compact W/E adjustable green laser. In another embodiment, the mode of the sight is switchable from constant to pulse, and vice versa. In another embodiment, the switch can be pushed to be ON or OFF. It is important to note that a further embodiment, the momentary sensor can be easily controlled especially for silent and quick operation. In still a further embodiment, the charging socket has a built-in rechargeable battery compatible with USB Type-C charger.
The sight can be attached to a firearm. The user can first loosen the locking screws of the sight, push/hold the locking screws, align the locking screws with the groove of the rail of the firearm, clamp the sight onto the rail of the firearm, and tighten the locking screw to complete the mounting process.
When in use, the user can press the switch to turn on the sight. In one embodiment, the momentary sensor can emit infrared light and if the infrared light is deflected, the laser beam emitted from the laser sight will be turned off. So, if the user wants to turn off the laser beam, the user can simply move the finger toward the momentary sensor to somewhat covers the momentary sensor to deflect the infrared light emitting therefrom. In one use case, when the firearm with the sight is disposed into a gun bag, the momentary sensor can still be triggered to turn off the laser beam.
It is noted that the momentary sensor is configured to temporarily shut off the laser beam. Namely, when the user moves the finger away from the momentary sensor, the infrared light emitting therefrom is not deflected and the laser beam from the laser sight can again be turned on. It is also noted that the switch has to be “ON” to trigger the momentary sensor.
In a further embodiment, the sight can be charged through the charging socket. More specifically, one end of a USB charging cable can be plugged into the charging socket on the sight and the other end can be connected to a USB power adapter to complete the charging process.

When in use, the user can press the switch 120 to turn on the sight 100. The momentary sensor 121 is configured to periodically emit a testing light with a predetermined frequency and detect the strength of a reflexed testing light to determine whether to shut off the laser beams. In one embodiment, the momentary sensor 121 can emit infrared light and if the infrared light is deflected by the user's finger to cause the change of the strength of the reflexed infrared light, the laser beam emitted from the laser sight 130 will be turned off. So, if the user wants to turn off the laser beam, the user can simply move the finger toward the momentary sensor 121 to somewhat covers the momentary sensor 121 to deflect the infrared light emitting therefrom. In one use case, when the firearm with the sight 100 is disposed into a gun bag, the momentary sensor 121 can still be triggered to turn off the laser beam.
It is noted that the momentary sensor 121 is configured to temporarily shut off the laser beam. Namely, when the user moves the finger away from the momentary sensor 121, the infrared light emitting therefrom is not deflected and the laser beam from the laser sight 130 can again be turned on. It is also noted that the switch has to be “ON” to trigger the momentary sensor 121.
