Description of the Related ArtThanks to the ongoing development of technology, electronic products such as sighting devices are becoming increasingly versatile. For example, such devices can be mounted or disposed on a hunting implement such as a hunting rifle, to aid in targeting game. The possible applications of such devices grow as newer models continue to offer high performance. Traditional sighting devices for hunting game usually includes a mirror or a glass where an aim point is shown thereon, and the user directly watches the target and the aim point shown on the glass to aim at the target by eye. However, when hunting in the early morning or close to night, it is difficult for the user to sight a target using only his or her eyes. Therefore, to provide a good product design which is convenient for the user and easier to operate is an important issue.

The making and using of the embodiments of the sighting devices are discussed in detail below. It should be appreciated, however, that the embodiments provide many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the embodiments, and do not limit the scope of the disclosure.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It should be appreciated that each term, which is defined in a commonly used dictionary, should be interpreted as having a meaning conforming to the relative skills and the background or the context of the present disclosure, and should not be interpreted by an idealized or overly formal manner unless defined otherwise.
As shown in
In this embodiment, the sight module 10 may be a gun sight or crossbow sight that is configured to sight or aim at a target, and it is able to mount on a shooting device (e.g. hunting rifle or crossbow) for accurate hunting shoot. The rangefinder module 20 can transmit an infrared beam or laser beam to measure the distance from the rangefinder module 20 to the target. Here, the first clamp member C1 of the securing mechanism is affixed to the bottom surface of the rangefinder module 20 by screws. In some embodiments, the first clamp member C1 may be detachably attached to the rangefinder module 20 by magnets or hook-and-loop fasteners.
The sight module 10 in
In this embodiment, the rangefinder module 20 is disposed above the sight module 10, and it may be a laser rangefinder which uses a laser beam to determine the distance to the target. For example, the rangefinder module 20 can emit a laser pulse toward the target and start timing, and then stop timing when the reflected light is received.
Still referring to
In this embodiment, the rangefinder module 20 can transmit a laser beam to a target through the window 23, and the laser beam can be reflected by the target and enter the rangefinder module 20 via the window 23, whereby the distance between the rangefinder module 20 and the target is determined. The distance information between the rangefinder module 20 and the target is then displayed on the digital numeric display 24, so that the user can make an accurate hunting shot via the sighting device.
For example, the digital numeric display 24 may be a seven segment display that is suitable for use outdoors in the dark, wherein the seven segment display may comprise a plurality of red, blue, white, yellow, green or yellow-green LEDs. However, the digital numeric display 24 may also be an LCD, OLED or touch display. When the user is inactive and the system is idle for a certain period of time (e.g. 3 to 5 minutes), the rangefinder module 20 can automatically turn off the digital numeric display 24 and switch into a low power mode for power saving. Additionally, a cable may be used to electrically connect the rangefinder module 20 to a power bank or computer via the connection port 25 (e.g. USB port), whereby a rechargeable battery inside the rangefinder module 20 can be charged even during usage.

On the contrary, when the user does not need the rangefinder module 20, the rotating quick-release lever L can be rotated around the axis A in a direction opposite to the predetermined direction, so that the quick-release lever L and the third clamp member C3 are loosen from the first clamp member C1. Therefore, the rangefinder module 20 can be rapidly detached from the recess R to achieve convenient disassembly of the sighting device.

Specifically, when the user is inactive and the system is idle for a certain period of time (e.g. 3 to 5 minutes), the rangefinder module 20 can automatically turn off the digital numeric display 24 and switch into a low power mode for power saving. As shown in
In summary, the invention provides a sighting device configured to aim at a target. The sighting device includes a sight module, a rangefinder module, and a securing mechanism configured to detachably secure the rangefinder module to the sight module. Since the securing mechanism includes several clamp members and is easy to assemble, the rangefinder module can be easily mounted on the sight module, so that the user can make an accurate hunting shot via the sighting device. Moreover, as the rangefinder module has a seven segment display, it is especially suitable for use outdoors in the dark. In some embodiments, the seven segment display of the rangefinder module may comprise a plurality of red, blue, white, yellow, green or yellow-green LEDs, so that it is also suitable for red-green or blue-yellow colorblind users.
