JP2002343106A - Magnifying glass desk lamp with hood - Google Patents

Abstract

PROBLEM TO BE SOLVED: To protect scattering light other than illuminating light which accompanies a desk lamp having a magnifying glass, to fix a free bending arm certainly, and in addition to attach it to a desk or the like, simply. SOLUTION: As a protecting means against scattering light other than illuminating light which accompanies a desk lamp having a magnifying glass, a space is prepared with a hood constituted by using dust absorption textiles around the magnifying glass. Further, as a fixing method for fixing the free bending arm or the apparatus, the method having a mechanical structure copes with it.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is an improvement of a loupe lamp.

[0002]

2. Description of the Related Art Conventionally, a desk lamp with a loupe has been widely used in processes such as processing and assembling precision instruments such as watches, cameras, jewelry, and the like. Although a desk lamp with a lamp is widely used, fine adjustments can be made when diffuse light or dust other than the attached light source enters between the position to be inspected and the lens, causing problems or changing the lighting angle of the lamp. Was extremely difficult to do.

[0003] In addition, if the loupe is made larger, the roof house becomes larger and the weight also increases. Therefore, in the case of the column of the coil spring type, even if the contact vibration is extremely unstable, even if the contact vibration is extremely weak, the position to be projected and viewed may be changed. I was

Further, when fixing a desk lamp or the like with a loupe to a desk or the like, since most products are of a screw knob type from the bottom, they cannot be visually recognized in a narrow place and are inconvenient to attach and detach.

[0005]

As described above, as described above,
Conventionally used desk lamp with loupe has many factors that are extremely unstable in use.In the present invention, the above-mentioned problems are solved, the desk lamp can be easily fixed, and strong against vibration. It is an object of the present invention to manufacture a desk lamp with a loupe that can easily set an angle with respect to an article to be illuminated.

[0006]

According to the present invention, as a measure for shielding scattered light other than a light source attached to a desk lamp with a loupe as much as possible to prevent dust adhering to the loupe, a dust-absorbing cloth is provided around the loupe. A space using a hood made of cloth is set to cope with the problem, and fine adjustment of the angle of the device and quake resistance are to be solved by using a gas-filled spring.

[0007] Also, as a measure to easily attach to a desk or the like,
It is intended to adopt a mechanical system.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 shows a procedure for shielding the scattered light other than the light source attached to the loupe with a loupe as much as possible to prevent dust adhering to the loupe. This shows a state in which a hood 3 made of a material in which a dust-absorbing woven fabric is bonded to a base material is used. In the figure, three directions are shielded. It is safe to block the direction.

The hood 3 is structured so that it can be easily attached and detached as necessary, and is constituted by a plurality of hoods so that attachment and detachment in only the required direction can be easily performed.

FIG. 3 is a view showing an apparatus for fixing the freely refracting arm 5 and the support 6. Conventionally, when such a flexible arm is used, a method of fixing with a coil spring is often used. However, as shown in FIG. 1, the load acting on the fulcrum 200 can withstand the amount of force applied to the power point 100. In the present invention, an oil damper 7 is employed at this fulcrum.

The pressure resistance capacity of the oil damper 7 is calculated based on a loupe, a lighting fixture, a hood, and the like attached to the power point. A lock knob for fixing was also used.

As shown in FIG. 4, the mechanism for fixing the machine to a desk or table uses a one-touch clamp system in which the fastener 11 slides and opens and closes by movement of a lever 10 set at a visible position.

[0014]

According to the present invention, when observing an object using conventional equipment, even if the illumination angle is fixed, an error occurs in the illumination angle due to vibration caused by a slight contact, so that it takes time to make fine adjustments and diffuse light from the outside. Although light rays penetrated and lacked accuracy in measuring objects, they can be easily fixed to a desk or the like by using the device of the present invention, and there is no influence of vibration etc. applied to the device, and scattered light beams from the outside Has been able to cope with intrusion by removing and attaching a plurality of shielding plates.

Further, due to the effect of the dust-absorbing woven fabric attached to the hood, fine dust adhering to the loupe has been significantly reduced.
