  • Fig. 1 is a perspective view showing a headlamp proof loupe system proposed in the present invention worn on the head.
  • This embodiment is composed of a light source (2), a headband (3, 4, 5, 6), and a loupe (7) mounted on the light source.
  • the headband is a ‘C’ shaped headband when viewed as a whole, extending from the forehead through the crown to the back of the head, and is composed of a front band (3), a front auxiliary band (4), a rear band (5), and a band size adjustment device (6).
  • the light source (2) generates light and shines it downward to illuminate a work area at a certain distance from which the objective lens of the loupe (7) is directed.
  • the light source (2) is hinged to the front band (3) on the opposite side from which the light is emitted, so that the direction of the light generated from the light source (2) can be changed up and down on the sagittal plane of the wearer.
  • the front band (3) is a long and thin member in the shape of the letter ‘S’ overall, hingedly connected to the light source (2) from the front downward, and has a square hole in the middle that accommodates the connecting portion (42) of the front auxiliary band (4) extending from the rear to the front, and a vertical hole (33) that is long and narrow in the vertical direction penetrating the square hole left and right so that a fixing screw (44) can pass through, and is connected to the rear band (5) from the rear upward so that the length can be adjusted.
  • the rear band (5) is a structure that supports the back of the wearer’s head, is connected to the front band (3) from the front so that the length can be adjusted, and has a battery compartment (51) that accommodates a battery at the rear.
  • the front auxiliary band (4) has a connecting portion (42) that protrudes forward and downward in the middle, and has wing portions (41) that extend left and right from the connecting portion and come into contact with the wearer’s forehead at the rear.
  • FIG. 2 is a side view from the left showing the headlamp proof system proposed in the present invention worn on two heads with different head shapes, that is, on a large head (11) in the left figure and on a small head (12) in the right figure.
  • the shape of each person's head is different.
  • the height of the eyes (13) of the large head (11) and the eyes (14) of the small head (12) are depicted as being the same.
  • the difference in the length from the forehead to the back of the head is resolved by the band size adjustment device (6) mentioned in FIG. 1. Adjusting this length is not difficult, but since it is not the subject of the present invention, a detailed description thereof will be omitted.
  • the differences in the shapes of the large head (11) and the small head (12) that are related to the present invention are as follows. First, the horizontal distance from the eyes (13) of the large head (11) to the point (P) where the central lower part of the front auxiliary band wing (41) and the front part of the forehead (15) of the large head (11) meet is 20.08 mm. The horizontal distance from the eye (14) of the small head (12) to the point (Q) where the lower center of the front auxiliary band wing (41) and the front part of the forehead (16) of the small head meet is 24.08 mm. That is, in the case of the large head (11), the eye (13) protrudes 4 mm further forward compared to the lower center of the forehead (15) in comparison to the small head (12).
  • the vertical distance from the eye (13) to the point (P), that is, the point (P) where the lower center of the front auxiliary band wing (41) and the front part of the forehead (15) meet is d2 longer than the vertical distance from the eye (14) of the small head (12) to the point (Q), that is, the point where the lower center of the front auxiliary band wing (41) and the front part of the forehead (16) meet.
  • the angle of inclination of the forehead (15) of the large head (11) is closer to vertical than the angle of inclination of the forehead (16) of the small head (12).
  • the ‘C’ shaped headband presented in this embodiment can rotate clockwise or counterclockwise around the center (O1, O2) of the circle formed by the three points (P, R, T) for a large head (11) and three points (Q, S, U) for a small head (12), regardless of the head shape. This rotation allows the light source (2), the loupe (7), and the front auxiliary band (4) to move up and down.
  • the headband rotates clockwise, the light source (2), the loupe (7), and the front auxiliary band (4) rise, and when the headband rotates counterclockwise, the light source, the loupe, and the front auxiliary band descend.
  • the angle between the line segment connecting the center of rotation (O1) to point P and the line segment extending horizontally from point P is 8.64 degrees
  • the angle between the line segment connecting the center of rotation (O2) to point Q and the line segment extending horizontally from point Q is 11.21 degrees.
  • the headband on the big head (11) is rotated 2.57 degrees more counterclockwise than the headband on the small head (12).
  • the light source (2) and the loupe (7) move downward by a distance obtained by multiplying the radian value of 2.57 degrees by the distance from the center of rotation (O1) to the radius of rotation.
  • the headband can be rotated to move the loupe (7) eyepiece to near the height of the eyes (13).
  • the light source (2) and the loupe (7) are rotated counterclockwise by the above 2.57 degrees, and this angular change also changes the angle of the optical axis of the loupe (7) eyepiece.
  • the light source (2) and the front band (3) are hinged together. More specifically, when the light source (2) is rotated clockwise by the angle at which the headband is rotated around the hinge axis (31) with respect to the front band (3), i.e., by 2.57 degrees, the angle of the optical axis of the loupe (7) eyepiece does not change.
  • the height of the eyepiece of the loupe (7) may be slightly lowered by the light source (2) rotating about the hinge axis (31), but this height change is much smaller than the height change caused by the rotation of the headband and can be ignored. Even if it cannot be ignored, the problem can be solved by rotating the headband less enough to compensate for it.
  • the light source can rotate independently of the headband, it is possible to align the optical axis of the loupe eyepiece mounted on the light source with the wearer's line of sight.
  • FIG. 3 is a partially enlarged view of the headlamp proof system proposed in the present invention, showing the embodiment worn on a large head (11) in detail to illustrate the method of combining the front band and the front auxiliary band.
  • FIG. 3 illustrates the state in which the left side of the square hole (32) of the front band (3) is removed to clearly illustrate the state in which the front band (3) and the front auxiliary band (4) are combined.
  • the removed cross-section (34) is indicated by gray hatching.
  • the combination of the front auxiliary band (4) and the front band (3) will be described in detail.
  • a square hole (32) is formed from the rear to the front to accommodate the front auxiliary band (4) combination portion (42), and vertical holes (33) are formed in the left and right sides of the square hole, extending vertically in the left and right directions.
  • the front auxiliary band (4) has a connecting portion (42) protruding downward in the center, and a horizontal hole (43) having a long horizontal shape is bored left and right in the connecting portion.
  • the width of the square hole (32) from left to right is slightly larger than the width of the connecting portion (42) of the front auxiliary band (4), so that the connecting portion (42) can be inserted into the square hole with some space.
  • This front auxiliary band (4) can achieve the following three purposes. First, the forward and backward movement of the front auxiliary band (4) changes the distance between the eye (13) and the eyepiece of the loupe (7). Second, the front auxiliary band can be moved vertically to some extent to fit depending on the vertical distance from the front center lower end (P) of the forehead (15) to the crown of the head or depending on the vertical distance from the front center lower end (P) of the forehead (15) to the eye.
  • the front auxiliary band (4) is stably supported by contacting the lower end (P) of the forehead (15), and the rear side of the wing portion (41) of the front auxiliary band (4) is closely fitted according to the slope of the forehead (15), providing comfort to the wearer.
  • the horizontal distance from the lower end of the forehead to the eye varies greatly from person to person.
  • the length of the horizontal hole (43) of the front auxiliary band (4) must be greatly increased.
  • the length of the horizontal hole (43) of the front auxiliary band (4) is determined at an appropriate level considering only the relationship with the forehead, and it is better to additionally apply a means for changing the position of the loupe mounted on the light source.
  • FIG. 4 is a partial perspective view of an embodiment of the present invention in which the headlamp light source (2) and the loupe are separated.
  • the light source (2) has a pair of left and right arms (21) protruding rearward at the bottom, and four catches (23) protrude outward at regular intervals on the outer surfaces of each pair of arms.
  • the catches (23) are positioned between the loupe frame (71) and the next catches (24). At this time, the catches (23) serve to prevent the loupe from easily moving forward and backward.
  • the rear part of the second, third, and fourth catches is formed as a catch slope (25), and this catch slope (25) is inclined at an angle of about 45 degrees with respect to the protrusion direction of the catches (23), so that when the arm (21) is inserted into the loupe (7), it comes into contact with the hole slope (76) of the loupe and easily slides.
  • the loupe is composed of left and right magnifying glasses (73, 72), a loupe frame (71) that supports the left and right magnifying glasses, and a fixing lever (8).
  • Fig. 4 is illustrated with the front part of the right magnifying glass (72) removed.
  • the loupe frame (71) has an insertion hole (74) drilled in the front-back direction in the center, and a pair of left and right arms (21) extending from the light source (2) are inserted into this insertion hole.
  • the insertion hole (74) is narrow at the top and wide at the bottom, and the frontmost part of the insertion hole is connected to the front surface (77).
