Description

  The present invention relates to a head-mounted magnifier equipped with a magnifying glass at the tip and mounted on the head, and relates to a commercially available product called a head loupe with a light source.

  The commercially available head magnifiers with light sources have been widely used when people with presbyopia or poor vision work finely in places with insufficient illuminance, etc., but the user operates the manual switch that is the operating means. For example, when a person working with a head loupe with a light source suddenly raises his face, or asks something When facing each other, the user is distracted by the light of the light source in the light-emitting state and makes others feel uncomfortable, so the user interrupts the work each time and manually operates the manual switch to extinguish the light. In addition to the trouble of manually operating the manual switch after turning off the head loupe with the light source, the light is emitted until the switch is manually operated and turned off. With wear It was those.

  The present invention has been made in consideration of such circumstances, and is provided with operation means for emitting and extinguishing light according to the intention of the user in a state where both hands are not used (hereinafter referred to as hands-free). Even if it is free, it automatically emits light when necessary, and can be extinguished when it is not needed.In other words, it can automatically emit or extinguish the light emitting part easily and in a short time when necessary, and wasteful use of power The purpose is to reduce energy consumption.

  According to the above-mentioned purpose, the first aspect of the present invention provides a light emitting unit provided so as to illuminate the front of a head loupe with a light source, and whether the elevation angle of the head loupe with a light source is an angle on the elevation side with respect to a reference angle. Angle detecting means for detecting whether or not, and an operating means for making the light-emitting part in a light-emitting state or a light-extinguishing state according to a user's operation, wherein the elevation angle is an angle of an elevation angle with respect to the reference angle In this case, the light emitting unit is quenched regardless of the operation of the operating means.

  According to the first aspect of the present invention, when the head loupe with a light source mounted with the operating means in a light emitting state is at an elevation angle with respect to the reference angle, the light emitting unit is extinguished regardless of the operation of the operating means. . For example, in a place where a person with reduced visual acuity has insufficient illuminance, when the head loupe with the light source is mounted and the face is directed toward an object provided on the depression side with respect to the reference angle, The attached head loupe has a depression angle with respect to the reference angle, and the light emitting part emits light. Therefore, the illumination of the light emitting part is added to the object enlarged through the magnifying glass so that the object can be easily seen. Further, when the elevation angle of the head loupe with light source is an elevation angle with respect to the reference angle, the light source is automatically extinguished regardless of the operation of the actuating means. When the head loupe with the light source is at an elevation angle side from the reference angle with the eyes raised away from it, the light source will automatically be extinguished, so that others will not be dazzled by the light of the light emitting part and feel uncomfortable Further, since the light is extinguished during the non-working time, that is, while looking away from the work object, the power is wasted and energy can be saved.

  The head loupe with a light source according to the second aspect of the present invention is provided with a function for adjusting the reference angle in the angle detecting means according to the first aspect of the present invention so that the user can arbitrarily change the reference angle.

  Considering the necessity of changing the irradiation angle depending on the shape, position or color of the work object when using the head loupe with a light source, the reference angle can be adjusted as in the second aspect of the present invention. desirable.

The head loupe with a light source according to the third aspect of the present invention includes a plurality of angle detection means capable of adjusting the reference angle in the previous period and a plurality of lamps in a light emitting unit corresponding to the angle detection means. For example, a total of three lamps, one lamp and two sets of lamps, can be used for two types of use, and whether the elevation angle is an elevation angle with respect to the reference angle Two types of angle detection means are provided for detecting whether or not, and the first angle detection means is a head loupe with a light source having a “horizontal state” as a first reference angle, if the angle is a depression angle from the reference angle. One lamp is turned on, and the second angle detection means has a head loupe with a light source that has two elevation angles if the elevation angle is greater than the second reference angle, with “15 degrees elevation from horizontal” as the second reference angle. The lamp is turned on. Therefore, if the head loupe with the light source is downward from the first reference angle “horizontal”, the first angle detection means turns to a depression angle from the first reference angle and turns on one lamp. The second angle detection means is directed downward from the second reference angle “15 ° elevation from horizontal” and is at a depression angle from the second reference angle, so that the two lamps are turned off.
On the contrary, when the head loupe with light source is at an angle of elevation from the second reference angle, the two lamps are turned on. At this time, the first angle detection means has an angle of elevation from the first reference angle. Since the angle is set, the one lamp is turned off.

  That is, the third aspect of the present invention described above is the first angle detection means for turning off the lamp when the angle of elevation is higher than the set reference angle, and the second angle detection means for turning on the lamp when the angle of elevation is higher than the separately provided reference angle. Thus, the illumination of the light emitting part can be properly used according to a plurality of uses required by the user. For example, for the local illumination, the first reference angle is detected by the first angle detection means. While one lamp is turned on, the second reference angle is detected by the second angle detection means for remote illumination so that two lamps can be turned on. . The plurality of angle detection means used in the third aspect of the present invention may be fixed at a predetermined angle.

  The light source-equipped head loupe according to the fourth aspect of the present invention includes the first to third aspects of the present invention provided with means for adjusting the light emission amount of the light emitting section.

  When using the above-mentioned head loupe with a light source, it is desirable to have a mechanism for adjusting the light emission amount of the light emitting unit according to the position, shape, or color of the work object, and the appropriate light emission amount varies depending on the work object. It is desirable to adjust the light emission amount of the light emitting unit. That is, in order to obtain a desired brightness for the work object, it is desirable to adjust the light emission amount of the light emitting unit according to the ambient illuminance. Therefore, it is preferable that the light emission amount of the light emitting portion as in the fourth aspect of the invention can be adjusted.

  As described above, the head loupe of the present invention is a light source that can quickly switch between light emission and extinction of the light emitting unit in accordance with the operation intended by the user, that is, a light source that can emit and extinguish the light emitting unit in a hands-free manner according to the user's intention. A head loupe with a head is provided. Furthermore, the present invention allows the angle of illumination to be changed by changing the reference angle of the angle detection means for the user to operate it intentionally, and allows the amount of light emission to be adjusted according to the color and shape of the object. Thus, the application of the head loupe is expanded. In addition, by quickly emitting or extinguishing the light emitting portion by the above operation, it is possible to reduce useless lighting time and save energy.

  Hereinafter, a head loupe with a light source according to the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of a head loupe with a light source according to an embodiment of the present invention, and FIG. 2 is a side view showing an operation (light emission) state of the head loupe with a light source.

The head loupe 1 with the light source of the present invention 1 includes a light emitting unit 2 using a discrete white LED lamp 2a, a power source unit 3, a slide switch 4 as an operation unit for turning on and off the power, and mercury used as an angle detection unit. The switch 5 is integrated, and the head loupe main body 1a is further integrated with a ring belt type head fixture.
In the following description of the embodiments, illustration and description of the electric circuit, wiring diagram, and battery of the power source are omitted. Further, the reference numerals and description of the magnifying glass 1s of the head loupe and the stopper 1t using the magic tape provided at the rear of the main body are omitted from FIG.

  In the embodiment of the present invention 1, in a state in which the slide switch 4 is turned on, the mercury switch 5 depends on whether or not the elevation angle of the head loupe body 1a is on the elevation side with respect to the reference angle. Emits and extinguishes light. That is, when the elevation angle of the head loupe main body 1a is on the depression side with respect to the reference angle as shown in the side view showing the operation state of FIG. The light emitting part is automatically extinguished.

  Therefore, the head loupe 1 with a light source of this embodiment is mounted on the head with the slide switch 4 turned on in advance, and if the main body 1a is at a depression angle from the reference angle, the light emitting part emits light in a hands-free manner. Since the target direction is illuminated and turned off when the angle is on the elevation angle side, for example, when the level of the head loupe main body 1a is set as the reference angle, the head loupe 1 with a light source is attached and the work is performed downward on the depression side. At that time, since the mercury switch 5 has an angle on the depression side with respect to the reference angle, the white LED lamp 2a is turned on, and when the operation is temporarily stopped and turned upward, which is on the elevation side, the angle is on the elevation side with respect to the reference angle. Therefore, since the white LED lamp 2a is extinguished, even if someone turns on and turns around, the white LED lamp 2a is immediately extinguished. There is no.

  FIG. 3 is a perspective view of a head loupe with a light source according to the second embodiment, and FIG. 4 is a side view showing an operating state.

  The light source-equipped head loupe 21 according to the second embodiment uses a light emitting unit 22 using a discrete LED lamp 22a, a power source unit 23, a slide switch 24 which is an operating means for turning on / off the power source, and a stop 25n. The mercury switch 25 of the angle detection means and the head loupe main body 21a that can vary the reference angle.

  In some cases, this type of head loupe with a light source is desirably viewed by changing the illumination angle of the light emitting unit depending on the position and shape of the work object. The reference angle can be changed by moving the mercury switch 25 as described above clockwise or counterclockwise.

  The mercury switch 25 that is the angle detection means provided in the head loupe main body 21 causes the light emitting unit 22 to emit light or extinguish by the operation of the head loupe main body 21 in a state where the slide switch 24 is turned on. That is, if the elevation angle of the head loupe main body 21 is an angle on the depression side with respect to the reference angle set by the angle detection means, the light emitting unit 22 emits light. Automatically extinguishes.

  As shown in the operation state of FIG. 4, for example, when the reference angle of the mercury switch 25 serving as the angle detection means is set to “10 degrees elevation from the horizontal” of the head loupe main body 21, the depression angle side from the “10 degrees from the horizontal” If the angle is, the light emitting unit 22 emits light. Accordingly, even if the head loupe main body 21a is at an elevation angle from the horizontal, if the head loupe body 21a is on the depression side within the range of the reference angle, the light emitting unit 22 is turned on, so that the illumination can also be performed from below within the range of the reference angle. In addition to providing easy-to-see illumination even when viewing at a different angle of the object, the light-emitting unit 22 emits light and extinguishes hands-free according to the user's intention, thereby reducing power consumption and reducing energy consumption.

  FIG. 5 is a perspective view of a head loupe with a light source according to a third embodiment, and FIG. 6 is a side view showing an operating state.

  A head loupe 31 with a light source according to a third embodiment includes a light emitting unit 32 and a power source unit 33 having a plurality of discrete white LED lamps 32a, 32b, and 32c, and a slide switch that is an operating means for turning on and off the power source. 34 and a stop 35an (not shown), a mercury switch 35a used as a first angle detector that can change the reference angle, and a mercury switch 35b that allows the reference angle to be changed by a stop 35bn used as a second angle detector. Further, the head loupe main body 31a is mounted on a pair of stoppers 31n as a shaft, and is configured by a ring belt type head fixing tool 31v attached so as to be moved up and down.

  In the present embodiment, for example, mercury switches 35a and 35b are used as two types of angle detection means capable of changing the reference angle, and the light emitting unit 32 is selectively used for two-way illumination according to two types of applications assumed in advance. When the LED lamp 32a is turned on by the mercury switch 35a which is the first angle detection means and used as the hand illumination, the LED lamps 32b and 32c are turned on by the mercury switch 35b which is the second angle detection means and the other side is illuminated. It can be used for two types of applications.

  In the third embodiment, for example, the first reference angle is set to the first reference angle by changing the angle of the mercury switch 35a, which is the first angle detection means, clockwise or counterclockwise around the stopper 35an (not shown). When the head loupe main body 31a is on the depression side with respect to the first reference angle, the LED lamp 32a is lit to illuminate the hand while the mercury switch 35b as the second angle detection means is set. When the angle is changed in the same manner as described above with the stopper 35bn as an axis, the second reference angle is set to “15 ° elevation angle from the horizontal” of the head loupe body 31a, and the LED lamp is turned on when the body 31a is on the elevation side from the second reference angle. 32b and 32c are turned on to illuminate the other side. That is, as shown in FIG. 6, when the head loupe main body 31a is at an elevation angle from the “horizontal” and within an angle of depression from the “15 ° elevation from the horizontal”, the first angle detection means is the LED lamp 32a. Since the second angle detection means turns off the LED lamps 32b and 32c, the light emitting section 32 is turned off.

  As described above, in the present embodiment, for example, after the user of the head loupe 31 with light source turns on the slide switch 34, the head loupe body 31a with light source performs a hand operation at a downward angle that is a depression angle from the horizontal. The LED lamp 32a is turned on by the first angle detection means to illuminate the hand, and the light is turned off when the angle is higher than the first reference angle “horizontal”, while the head loupe main body 31a with the light source is The LED lamps 32b and 32c are turned on by the second angle detection means when the angle is higher than the reference angle “15 ° depression from the horizontal”, and the other side is illuminated. In this case, the head loupe main body 31a is turned off within a range of 15 degrees which is the sum of the first and second reference angles (FIG. 6). One LED lamps will light up either by. Therefore, the user can select and use two types of illumination in a hands-free manner by arbitrarily setting two types of reference angles as required. Further, by moving the head loupe main body 31a about the pair of stoppers 31n, the same operation as described above can be obtained, so that the LED lamp can be turned on and off without changing the orientation of the face. Moreover, in this embodiment, it is not necessary for all the LED to face the same direction, and you may change an angle suitably.
