DETACHABLE SIGHT WITH MOMENTARY SWITCH OF LIGHT WITH CONTROL LOGIC

Abstract

In one aspect, a sight with a momentary switch to control a laser beam on the sight may include a main power switch, a switch with momentary sensor, a plurality of locking screw to lock the sight onto a firearm, an orifice for emitting laser beams, a charging socket, and a laser adjustment screw. When in use, the user can press the main power switch to turn on the sight. In one embodiment, the switch with momentary sensor can emit infrared light and if the infrared light is deflected, the laser beam 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 therein.

Claims

1. A sight for a firearm comprising: a main body; an orifice that emits a laser beam; and a main power switch, and a switch with a momentary sensor to control the laser beam; wherein the momentary sensor 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 temporarily shut off the laser beam, and wherein when the reflexed testing light is not deflected, the laser beam will stay on, while the main power switch is on.

2. A sight for a firearm of claim 1, wherein the laser beam can be shut off when the testing light is deflected to cause the change of the strength of the reflexed testing light.

DETAILED DESCRIPTION OF THE INVENTION

[0020] The detailed description set forth below is intended as a description of the presently exemplary device provided in accordance with aspects of the present invention and is not intended to represent the only forms in which the present invention may be prepared or utilized. It is to be understood, rather, that the same or equivalent functions and components may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the invention.

[0021] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs. Although any methods, devices and materials similar or equivalent to those described can be used in the practice or testing of the invention, the exemplary methods, devices and materials are now described.

[0022] All publications mentioned are incorporated by reference for the purpose of describing and disclosing, for example, the designs and methodologies that are described in the publications that might be used in connection with the presently described invention. The publications listed or discussed above, below and throughout the text are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as an admission that the inventors are not entitled to antedate such disclosure by virtue of prior invention.

[0023] As used in the description herein and throughout the claims that follow, the meaning of “a”, “an”, and “the” includes reference to the plural unless the context clearly dictates otherwise. Also, as used in the description herein and throughout the claims that follow, the terms “comprise or comprising”, “include or including”, “have or having”, “contain or containing” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. As used in the description herein and throughout the claims that follow, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise.

[0024] It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the embodiments. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

[0025] In one aspect, as shown in FIGS. 2 and 3, a sight 100 may include a main body 110, a main power switch 120, a switch with momentary sensor 121, an orifice 130 for emitting laser beams controlled by the main power switch 120 and the switch with momentary sensor 121, a plurality of locking screws 140 to lock the sight onto a firearm, a set of laser adjustment screws 150, and a charging socket 160. In one embodiment, the main body 110 is tactical low-profile and compact. In another embodiment, the laser beam emitted from orifice 130 is W/E adjustable. In another embodiment, the mode of the laser beam emitted from orifice 130 is switchable from constant to pulse, and vice versa. In another embodiment, the main power switch 120 can be pushed to be ON or OFF. It is important to note that a further embodiment, the switch with momentary sensor 121 can be easily controlled especially for silent and quick operation. In still a further embodiment, the charging socket 160 has a built-in rechargeable battery compatible with USB Type-C charger.

[0026] The sight 100 can be attached to a firearm as shown in FIG. 4. The user can first loosen the locking screws 140 of the sight 100, push/hold the locking screws 140, align the locking screws 140 with the groove of the rail of the firearm, clamp the sight onto the rail of the firearm, and tighten the locking screw 140 to complete the mounting process.

[0027] In an exemplary embodiment, a “Normal Close Switch” in the present invention is depicted in FIG. 5, where when the senor detects a reflection signal, the momentary switch would open the circuit and turn off the laser or light. On the other hand, when the reflection signal disappears, the momentary switch would close the circuit, and the laser would be turned on.

[0028] When in use, the user can press the main power switch 120 to turn on the sight 100. The switch with 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 can emit infrared light and if the infrared light is not deflected, the laser beam emitted from the orifice 130 will stay on according to the control logic shown in FIG. 5.

[0029] On the other hand, if the user wants to turn off the laser beam, the user can simply move the finger toward the switch with momentary sensor 121 to somewhat covers the switch with 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 switch with momentary sensor 121 can still be triggered to turn off the laser beam. For safety concerns, the user is required to put his/her index finger of the hand griping the pistol at finger rest position, i.e. on the side of the trigger guard, unless they are ready to shoot. It is noted that there are three mounting positions (140, 141, 142) on the sight 100 for user to adjust the mounting position to set the switches as much closer to the trigger guard as possible. Once the sight 100 are mounted at the position that user's index finger could reach, the user could use his index finger of the hand griping the pistol to temperately pause the laser. More importantly, when the user is ready to shoot, he merely needs to move the index finger away from the switch with momentary sensor 121 to the trigger, and the laser would be on at the moment of shooting. It is noted that the control logic in FIG. 5 applied in the present invention is the fastest way to active a laser.

[0030] It is also noted that the switch with momentary sensor 121 is configured to temporarily shut off the laser beam. Namely, when the user moves the finger away from the switch with momentary sensor 121, the infrared light emitting therefrom is not deflected and the laser beam from the orifice 130 can again be turned on. It is also noted that the main power switch 120 has to be “ON” to trigger the switch with momentary sensor 121.

[0031] In a further embodiment, the sight can be charged through the charging socket 160. More specifically, as shown in FIG. 6, one end of a USB charging cable can be plugged into the charging socket 160 on the sight 100 and the other end can be connected to a USB power adapter to complete the charging process.

[0032] Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalent.
