DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1, 2 and 3, a sight 100 of a first embodiment of the invention includes a body 110. Two adjusting dials 122 and 132 are respectively provided on two surfaces 111 and 112 of the body 110 for adjusting elevation and windage to correct the bullet impact point. A depression 114 extends from an edge of the surface 111 to the adjusting dial 122, facilitating the user to operate the adjusting dial 122 with his finger for the elevation adjustments. Similarly, a depression 115 extends from an edge of the surface 112 to the adjusting dial 132, facilitating the user to operate the adjusting dial 132 with his finger for the windage adjustments.

In addition to user's finger, a flat head screw driver can be selectively utilized to operate the adjusting dials 122 and 132. Specifically, a flat head screw driver can be utilized to turn fixing screws 121 and 131 respectively disposed on the adjusting dials 122 and 132, thereby achieving the purpose of adjustments of elevation and windage.

FIG. 4 is an exploded view of the sight 100 of the first embodiment of the invention, and FIG. 5 is a cross-sectional view along a cross-sectional line V-V of FIG. 2. Referring to FIGS. 4 and 5, a light source (e.g. a red light-emitting diode, LED) 150 is disposed on an adjusting seat 140. A light beam produced by the light source 150 is directed to a lens 160 and reflected to the user's eyes, so that the user can see a red dot on the lens 160. With the red dot aimed at a distant target, the user can pull a trigger to shot the target.

In view of the bullet impact point to be influenced by gravity and wind, the light source 150 is configured to be movable for correcting a bullet impact offset and maintaining the accuracy of fire. The sight 100 of the invention includes an elevation adjustment mechanism and a windage adjustment mechanism, described in detail as follows.

FIGS. 4 and 5 illustrate the elevation adjustment mechanism, wherein an adjusting axle 126 is connected to the adjusting seat 140. The adjusting axle 126 is vertically movable for driving the light source 150 disposed on the adjusting seat 140 to move upward and downward, thereby performing the elevation adjustment. The body 110 has an opening 113 allowing the adjusting axle 126 to pass through. The opening 113 of the body 110 fits the adjusting axle 126 in shape, so that the adjusting axle 126 can only be linearly moved but cannot be rotated. A screw nut 125 is fixed in the body 110. A hollow screw 124 has internal threads to inwardly engage with the adjusting axle 126, and external threads to outwardly engage with the screw nut 125 and the adjusting dial 122. A pressure ring 123 fixed in the body 110 is utilized to compress the hollow screw 124, so that the hollow screw 124 can only be rotated but cannot be linearly moved. The fixing screw 121 is fixed to the adjusting dial 122. Accordingly, when the adjusting dial 122 or the fixing screw 121 is rotated, the hollow screw 124 is driven for rotation, the adjusting axle 126 is driven for upward and downward movements, and the light source 150 disposed on the adjusting seat 140 is driven for upward and downward movements, thereby performing the elevation adjustment.

A spring 1241 and a steel ball 1242 are disposed on the hollow screw 124, in which the steel ball 1242 is compressed between the hollow screw 124 and the screw nut 125 via the spring 1241. A perception and sound of click can be produced when the user rotates the adjusting dial 122 or the fixing screw 121.

FIGS. 4 and 6 illustrate the windage adjustment mechanism, wherein an adjusting axle 136 is propped against the adjusting seat 140. The adjusting axle 136 is horizontally movable for driving the light source 150 disposed on the adjusting seat 140 to move left and right, thereby performing the windage adjustment. A convex axle 137, a spring 138 and a stop part 139 are disposed on a side of the adjusting seat 140. The convex axle 137 is fixedly connected to the adjusting seat 140. The spring 138 is outwardly sleeved on the convex axle 137 and propped against the stop part 139. The stop part 139 is fixed on the body 110. When the adjusting axle 138 is withdrawn, the adjusting seat 140 can be kept to contact the adjusting axle 136 by a recovery force of the spring 138. The body 110 has an opening 116 allowing the adjusting axle 136 to pass through. The opening 116 of the body 110 fits the adjusting axle 136 in shape, so that the adjusting axle 126 can only be linearly moved but cannot be rotated. A screw nut 135 is fixed in the body 110. A hollow screw 134 has internal threads to inwardly engage with the adjusting axle 136, and external threads to outwardly engage with the screw nut 135 and the adjusting dial 132. A pressure ring 133 fixed in the body 110 is utilized to compress the hollow screw 134, so that the hollow screw 134 can only be rotated but cannot be linearly moved. The fixing screw 131 is fixed to the adjusting dial 132. Accordingly, when the adjusting dial 132 or the fixing screw 131 is rotated, the hollow screw 134 is driven for rotation, the adjusting axle 136 is driven to move left and right, and the light source 150 disposed on the adjusting seat 140 is driven to move left and right, thereby performing the windage adjustment.

A spring 1341 and a steel ball 1342 are disposed on the hollow screw 134, in which the steel ball 1342 is compressed between the hollow screw 134 and the screw nut 135 via the spring 1341. A perception and sound of click can be produced when the user rotates the adjusting dial 132 or the fixing screw 131.

Referring to FIG. 7, a sight 200 of a second embodiment of the invention includes a body 210. Two adjusting dials 222 and 232 are disposed on the surfaces 211 and 212 of the body 210 for elevation and windage adjustments, respectively. The sight 200 of the second embodiment differs from the sight 100 of the first embodiment in that the adjusting dials 222 and 232 are protruded from edges of the surfaces 211 and 212 of the body 210. Thus, the adjusting dials 222 and 232 can be also directly driven by a user's finger. The rest structure of the sight 200 of the second embodiment is similar to that of the first embodiment and the descriptions thereof are omitted.

In conclusion, with the configuration of the adjusting dials of the sight which are capable of being driven by the flat head screw driver or directly driven by the user's finger for elevation and windage adjustments, the invention surely can provide conveniences of usability and portability.

While this invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
