Abstract

PROBLEM TO BE SOLVED: To provide a hand lighting apparatus by which fine work using fingertips can be performed, whose light volume can be easily adjusted, and which can be used even while a glove is worn.SOLUTION: A hand lighting apparatus includes an annular wearing part having elasticity to be worn so as to cover the palm and back of the hand, and a lighting part attached to the wearing part which is located on the palm side when the hand lighting apparatus is worn, and irradiates light. Since the lighting part is located on the palm side when the hand lighting apparatus is worn, a degree-of-freedom of fingertips increases and fine work can be performed easily. Also, since the wearing part has elasticity, the hand lighting apparatus can be moved to the wrist or the arm when performing work for which the hand does not need to be illuminated. Furthermore, since the light volume can be easily adjusted by a hand-opening degree, convenience can be improved significantly as compared with a conventional apparatus in which a switch needs to be operated for adjusting the light volume.

Description

The present invention relates to a hand lighting apparatus that is mounted on an operator's hand and illuminates only the vicinity of the hand.

Usually, when performing various operations such as writing, reading, work, repair, etc. in a dark environment, an operator needs to illuminate his hand with a flashlight or a headlight.
However, since the flashlight is held by either the left or right hand, there is a problem that it is not suitable for work using both hands, and the headlight is slightly out of focus with just moving the head position slightly. There is a problem of end. In addition, both the flashlight and the headlight have a problem that the light spreads over a wide area other than the operator's hand, which makes the surrounding people feel dazzling.
Therefore, as a lighting fixture intended to illuminate only the operator's hand, there is an appliance (see Patent Documents 1 to 4) that is used by winding a light around the operator's finger or back of the hand with an elastic belt or hook-and-loop fastener. Are known.

Utility Model Registration No. 3140354 JP 2008-84844 A JP 2011-60576 A JP 2013-145658 A

However, the above prior art has the following problems.
That is, there is a problem that what is worn on the finger of the hand becomes an obstacle when performing fine work using the fingertip. In addition, because the structure of what is attached to the back of the hand spreads to some extent other than the operator's hand, the problem of dazzling the surrounding people cannot be solved.
Also, both the ones worn on the fingers of the hand and the ones on the back of the hand are troublesome because it is necessary to operate a separate switch when adjusting the amount of light, or when performing work that does not need to illuminate the hand However, there is also a problem that it is necessary to remove the light from the finger or hand by releasing the restraint by the belt or the like, which takes time.
Further, for example, a nurse working in a hospital may work in a hospital room at night while changing thin translucent gloves many times from the viewpoint of hygiene management. Therefore, a hand-held lighting fixture that can be used even while wearing gloves and can be easily replaced is useful, but in the case of a lighting fixture to be worn on the finger of a hand, the light is caught on the finger part of the glove. There is a problem that gloves cannot be worn.

  In view of the above problems, an object of the present invention is to provide a hand lighting apparatus that can perform fine work using a fingertip, can easily adjust the amount of light, and can be used even when a glove is worn.

The hand lighting apparatus of the present invention is an annular ring having elasticity, and is mounted so as to cover the palm and the back, and is attached to the mounting part and is irradiated on the palm side when mounted. And an illuminating unit.
The illumination unit is detachable from the mounting unit.
Further, the direction of light irradiation by the illumination unit is variable.
Further, the mounting portion is made of silicone rubber.

In the hand lighting device of the present invention, the lighting unit is positioned on the palm side when worn. Therefore, the degree of freedom of the fingertip is increased compared to the case where the illumination unit is attached to the fingertip, and fine work can be easily performed.
Moreover, since the mounting portion has elasticity, the diameter of the mounting portion can be increased by pulling the annular mounting portion, and the hand lighting device itself can be moved to the wrist or arm. As a result, nothing is attached to the hand, so that finer work can be performed.
As for the adjustment of the amount of light, the hand may be opened wide when the hand is brightly lit, the hand is swung down when the hand is slightly lit, and the illuminating unit is gripped by hand when the light is almost completely dark. In this way, the entire hand functions like a lamp shade, and the amount of light can be easily adjusted by opening the hand, greatly improving convenience compared to operating the light amount adjustment switch as in the past. it can. In addition, since the light stays within the range surrounded by the palm of the operator and the light is less likely to leak to the outside, the surrounding people are not dazzled.

Moreover, a glove can be easily fitted without the illumination part being caught by positioning the illumination part in a slight gap generated between the hollow part of the palm and the glove. That is, a glove can be used in a state in which the hand lighting apparatus is attached to the hand, and a glove attachment / detachment (exchange) operation can be easily performed.
In addition, if the illumination part has a structure that is detachable from the mounting part, it is preferable in terms of hygiene management because only the mounting part can be cleaned with a detergent or soaked in a disinfecting solution or the like.
Further, by making the light irradiation direction by the illumination unit variable, it is possible to irradiate light only in a direction and range more preferable for the worker, and workability can be further improved.
Further, if the mounting portion is made of silicone rubber, it can be easily manufactured with an injection molding machine or the like, and is easy in terms of hygiene management because it is easy to clean and disinfect and is easy to dry.
