The structure as well as preferred modes of use, further objects, and advantages of this invention will be best understood by referring to the following detailed description of some illustrative embodiments in conjunction with the accompanying drawings, in which:
The sighting device 10 further includes a lens or at least one lens assembly 111 disposed in the accommodating space 12 of the body 11, and the reticle 13 is also disposed in the accommodating space 12 of the body 11. The body 11 can be a tube in which a first lens 113 and a second lens 115 are disposed respectively at two ends of the body 11, thereby forming an optical beam path between the first lens 113 and the second lens 115. The reticle 13 is positioned on the optical beam path between the first lens 113 and the second lens 115, for example, the first lens 113 can be ocular lens and the second lens 115 can be objective lens.
Referring to
The lighting unit 15 is disposed on the body 11 for generating a light, wherein the light generated by the lighting unit 15 is projected onto the reticle 13 to form a reticle pattern 133 on the reticle 13. When the marking 131, for example, is a crosshair, and the reticle pattern 133 is a crosshair, the crossing point of the crosshair of the reticle pattern 133 overlaps the crossing point of the crosshair of the marking 131.
In one embodiment, the lighting unit 15 is located on a side of the reticle 13, as shown in
In the embodiment of
The touch unit 17 is disposed on the body 11 for sensing an external touch and generating a touch signal corresponding to the external touch. The touch unit can be disposed on a side of the body 11 so the users can touch the touch unit 17 with fingers conveniently. The touch unit 17 shown in the figure is circular, but in practice the touch unit 17 can have a shape of a triangle, a square, a rectangular, or a polygon.
The controller 19 is disposed on the body 11 and electrically connected to the touch unit 17 and the lighting unit 15. The controller 19 receives the touch signal transmitted by the touch unit 17 and adjusts a brightness level and/or color of the light generated by the lighting unit 15 according to the touch signal.
In one embodiment, the touch unit 17 can be set to generate different touch signals base on the number of times the touch unit 17 is touched by the user, and the controller adjusts the brightness level and/or color of the lighting unit 15 according to the number of times the user touched the touch unit 17 and/or the touch signal. For example, when the touch unit 17 is touched just once, the lighting unit 15 is set to be the lowest brightness level, and when the touch unit 17 is touched again, the brightness level of the lighting unit 15 increases. Moreover, touching the touch unit 17 one more time would increase the brightness level of the lighting unit 15 more. Through this mode the brightness of light projected by the lighting unit 15 onto the reticle 13 can be adjusted.
In a different embodiment, the touch unit 17 can also generate different touch signals according to a touch position, and the controller 19 adjusts the brightness level and/or color of the lighting unit 15 according to the position on the touch unit 17 where the users touched and/or the touch signal. In one example, when the front end of the touch unit 17 or a position on the touch unit 17 that is closer to the second lens 115 is touched, the lighting unit 15 increases its brightness, and when the back end of the touch unit 17 or a position on the touch unit 17 that is closer to the first lens 113 is touched, the brightness level of the lighting unit 15 decreases. In practice, the touch unit 17 may be set to be touched by other different ways to adjust, through controlling the controller 19, the brightness level and/or color of the lighting unit 15. Therefore, the touch methods described in the above embodiments are merely examples of the invention and do not limit the scope of the invention. In one other embodiment of the invention, there are more than one touch unit 17, for example, two touch units 17, wherein when one touch unit 17 is touched, the brightness level of the lighting unit 15 increases, and when the other touch unit 17 is touched, the brightness level of the lighting unit 15 decreases.
As described, the invention discloses a sighting device 10 equipped with a touch unit 17, a controller 19, and a lighting unit 15 thereon, wherein the user can touch the touch unit 17 directly with fingers and change the brightness level and/or color of light generated by the lighting unit 15, thereby enhancing the convenience of the sighting device 10 during usage. Moreover, in comparison to controlling the light brightness level of the lighting unit 15 with physical buttons, using the touch unit 17 not only can reduce the size of the sighting device 10, but also can prevent water vapor from entering the sighting device 10, which in turn extends the usage life of the sighting device 10 and expands usage environments.
The touchpad 175 is electrically connected to the controller 19 and the mount 171 has an annular structure. The mount 171 mounts the touchpad 175 on the body 11, and because the surface area of the hollow portion of the mount 171 is smaller than the surface area of the touchpad 175, a part of the touchpad 175 placed in the hollow portion of the mount 171 is exposed externally to the outside environment, so that the user can touch the touchpad 175. In particular, when the touchpad 175 is coupled to the controller 19 and placed at a predetermined position on the body 11, the mount 171 is further placed over the touchpad 175, and mounted on the body 11 with securing elements 172, thereby completing the assembly of the touch unit 17.
In one of the embodiments, waterproof seals 173 are used to enhance the durability and waterproof of the touch unit 17, wherein one water proof seal 173 is disposed between the touchpad 175 and the mount 171 and another waterproof seal 173 is disposed between the touchpad 175 and the body 11. The waterproof seal 173 can be, for example, a rubber ring or an O-ring. In a different embodiment, a cushion 177 is disposed between the touchpad 173 and the body 11 and a protective cover 179 is disposed between the touchpad 175 and the mount 171 to provide more protection to the touchpad 175. The protection cover 179 can be made of glass or acrylic.
