The main body 110 constitutes an overall form of the apparatus 100 for eyeball angle measuring of the spectacle lens according to the present invention. The main body 110 includes first and second main bodies 110A and 110B which are separated and coupled to both sides. Components of the present invention described below are disposed in the inner space of the main body 110 formed by the combination of the first and second main bodies 110A and 110B.

In the present embodiment, the main body 110 is formed in a flat rectangular parallelepiped shape, but may be formed in another shape according to the needs of the user. However, one side of the main body 110 in contact with the front surface of the spectacle lens is preferably formed in a straight line to ensure the accuracy of the measurement.

One side of the main body 110 is formed with a slide groove 112 formed to a predetermined depth and length. The slide groove 112 is exposed to the inside of the fixed switch 134 to be described later, and the stopper 140 to be described later slides.

In addition, bearings 114 for fixing the rod rotating shaft 124 of the weight rod 122 to be described later are formed on the inner surfaces of the first and second bodies 110A and 110B.

The weight part 120 rotates in a predetermined direction according to the inclination of the contact surface while the main body 110 contacts the front surface of the spectacle lens.

The weight part 120 includes a weight rod 122 and a weight 126.

The weight rod 122 is formed in the shape of a rod having a predetermined length. One end of the weight rod 122 is connected to the rod rotating shaft 124 inside the main body 110, and the other end of the weight rod 122 is connected to a weight 126 having a predetermined weight. Accordingly, as the weight rod 122 contacts the front surface of the spectacle lens, the weight rod 122 may rotate based on the rod rotation shaft 124 to indicate a change in the angle of the contact surface of the main body 110. In order to facilitate the measurement of the angle change amount of the weight rod 122, an angle leader 128 formed in parallel with the weight rod 122 is displayed on the side of the weight 126.

The angle leader 128 indicates a scale formed on one side of the display window 150 to be described later according to the operation of the weight rod 122 and facilitates measurement of the measured angle.

The switch unit 130 interrupts the rotation of the weight rod 122. The switch unit 130 includes a switch body 132 and a spring 136.

The switch body 132 is formed in the form of a rod. The switch rotation shaft 133 connected to the inner side of the main body 110 is connected to the middle of the switch main body 110.

A fixed switch 134 is disposed at one end of the switch body 132 to be pressed by the user, and the other end of the switch body 132 is in contact with the rod rotating shaft 124 of the weight rod 122 by a user's operation. A pressing unit 136 for intermittent rotation of the rod 122 is disposed.

The pressing unit 136 may be formed in the shape of an arc according to the shape of the outer circumferential surface of the rotation shaft 124 of the weight rod 122.

The spring 138 applies an elastic force to one side of the switch body 132 so that the pressing unit 134 presses the rotation shaft of the weight rod 122. Except for the case where the user operates the fixed switch 134, the weight rod 122 is maintained by the elastic force of the spring 138.

The stopper 140 slides on the sliding groove 112 on one side of the main body 110 and fixes the fixed switch 134. The stopper 140 is formed in a hexahedral shape and is disposed to be movable on the sliding groove 112.

One end of the stopper 140, the locking projection 142 is formed. The locking protrusion 142 contacts one side of the fixed switch 134 by the operation of the stopper 140 and facilitates fixing of the fixed switch 134.

The display window 150 is formed at one side of the main body 110. The display window 150 cuts one side of the main body 110 so that the inside of the main body 110 is visible. The weight 126 of the weight rod 122 is exposed to the display window 150. The display window 150 is formed in an arc shape having a predetermined curvature. Here, the curvature of the display window 150 is equal to the rotational curvature of the weight 126 at the end of the weight rod 122 when the weight rod 122 rotates about the rotation axis, so that the weight rod 122 rotates. The movement of the weight 126 may be continuously monitored through the display window 150.

The width of the display window 150 may be formed in accordance with the diameter of the weight 126 exposed through the display window 150 to serve as a guider for guiding the movement of the weight 126 of the display window 150.

One side of the display window 150 may display an angle scale so that the rotation angle of the weight rod 122 may be easily grasped.

3 is an operation state diagram illustrating an operation of an apparatus for measuring the gaze angle of the spectacle lens illustrated in FIG. 1.

Referring to FIG. 3, first, the spectacle lens 10 is prepared.

Here, the spectacle lens 10 is a convex lens having a predetermined frequency. In addition, the spectacle lens 10 is preferably mounted in the spectacle frame so that the measurement is performed while the user wears the spectacles to ensure the accuracy of the measurement. However, in FIG. 3, the illustration of the user and the glasses frame is omitted for simplicity of the drawings. Although the drawings for the user who wears the spectacle frame and glasses are omitted in the drawings, the description of the use state of the present invention described below is assumed to be made while the user wears the glasses. In this case, the measurement may be directly performed by a user, but it is preferable that a separate tester performs the measurement.

At this time, it is preferable that the weight rod 122 is set to a 0 degree state for use of the measuring apparatus 100. Although the setting state of the weight rod 122 may be set to a state other than 0 degree, it is preferable to set it to 0 degree state before a measurement start in order to make angle measurement easy.

4 is an operation state diagram illustrating an operation state of the stopper of FIG. 1.

In order to prevent the setting state set before the angle measurement using this apparatus from changing, it is preferable that the stopper 140 is moved to the A position on the slide groove 112 so that the fixing switch 134 is not operated.

The user makes contact with the measuring device according to the present invention to the front of the spectacle lens 10. Here, the front surface of the spectacle lens 10 is formed of a curved surface having a predetermined curvature, and a portion of the main body 110 of the measuring device 100 that contacts the front surface of the spectacle lens 10 is in a straight line shape.

Therefore, when the measuring device 100 is in contact with the front surface of the spectacle lens 10, the upper and lower portions of the spectacle lens 10 are measured while one side of the measuring device 100 is in contact with the center of the spectacle lens 10. Measurements are made with the same spacing as one side of the device 100.

When the measurement is started, the user moves the stopper 140 to the B position to release the lock on the fixed switch 134, thereby making the fixed switch 134 available.

Thereafter, the user pushes the fixed switch 134 so that the pressing part 134 contacting the rotation shaft of the weight rod 122 is spaced apart from the rotation shaft 124, so that the weight rod 122 rotates the rotation shaft 124. It becomes the state which can be rotated freely as a reference. The weight 126 of one end of the weight rod 122 is directed toward the gravity direction according to the inclination of the measuring device 100, and thus the weight rod 122 is rotated about the axis of rotation.

The side of the weight 126 at the end of the weight rod 122 is exposed to the outside through the display window 150. The user may check the eyeball angle of the spectacle lens by looking at the weight 126 through the display window 150. Here, since a value obtained by adding 90 degrees to the measured angle is a gaze angle, the angle displayed on one side of the display window 150 is preferably displayed in consideration of this.

At this time, the angle indicator line 128 is displayed on one side of the weight 126, so that the angle value displayed on one side of the display window 150 can be easily read.

If the rotation angle is displayed on one side of the display window 150, the user may further check the rotation angle of the weight rod 122 using the rotation angle.

When the angle check through the display window 150 is made, when the pressing operation of the fixed switch 134 is released, the pressure part 134 contacts the rotating shaft 124 so that the weight rod 122 does not rotate, so that the weight rod It is prevented that the angle confirmation becomes difficult by the vibration of 122.

At this time, even when the weight rod 122 is rotated without releasing the pressing operation of the fixed switch 134, the weight rod 122 is temporarily brought into contact with the front surface of the spectacle lens 10. ) Rotation is stopped. If the tester has a lot of experience in using the measuring device 100, the rotation angle of the weight rod 122 is checked using the moment when the rotation of the weight rod 122 is stopped without releasing the pressing operation of the fixed switch 134. Can be performed. In this case, there is an advantage that the measurement time can be shortened.

After the angle check through the display window 150 is completed, the tester may perform re-measurement while the weight rod 122 is freely rotatable with respect to the rotation shaft 124.

When the measurement of the lens of one side of the two lenses constituting the glasses is completed, the measurement of the lens of the other side is performed to determine whether the gaze angle of both lenses of the glasses are the same.

According to the present invention configured as described above, in the state in which the spectacle lens is mounted on the frame and the user wears the spectacles, the eye contact angle of the spectacle lens may be measured by contacting the measuring device with the front surface of the lens.

In addition, it is possible to measure whether the eye angles of both lenses of the glasses are the same.

While the present invention has been described with reference to exemplary embodiments, 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. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
