Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable light, and more particularly to a flashlight, a small lamp, a work auxiliary lamp and the like.

[0002]

2. Description of the Related Art Conventionally, various types and sizes of portable lights and flashlights have been sold and used according to the place of use and the situation. Most of the flashlights used when there is a power outage in a house are cylindrical handy type, and as the ones used for camping camps and security, the caliber of the light emitting part, the battery and the charging part are compared. Large lights are prepared. Furthermore, recently, a pen-type light having a small amount of light and a large amount of light emission is commercially available.

[0003]

By the way, in each light described above, the light emitting portion is fixed to the tip of the grip portion of the light, which is inconvenient when the user wants to change the irradiation area of the light. there were. Specifically, for example, when a nurse examines a patient (taking a pulse, measuring a body temperature, or taking an infusion) at a hospital at night, the lighting of the entire room is turned on so as not to wake up other patients. Instead, they often work with a flashlight. However, since it is difficult to carry out the work when the flashlight is held in one hand, the work is carried out after the flashlight is once placed on the bed side table, the bedside of the patient, or the like. However, as work, in addition to medical examinations and infusions, there are things such as recording the results of medical examinations in a notebook, checking the materials about the patient, etc., and changing the irradiation direction each time by taking up a flashlight etc. It had to be done and was very inconvenient.

Therefore, in view of the above problems, the object of the present invention is to simply change the irradiation direction in a work requiring a light irradiation such as a nursing work of a nurse at night or in a field. The purpose of the present invention is to provide a portable light whose irradiation direction can be fixed as it is to improve workability.

[0005]

In order to achieve the above object, a portable light according to claim 1 of the present invention comprises a main body having a power source, a flexible portion which can be bent, and a tip of the flexible portion. The light emitting section is provided in the flexible section, and the flexible section has a built-in energization section for supplying electric power from the power source section to the light emitting section. As described above, since the flexible portion is provided with only the conducting portion and the power source portion for sending electricity to the light emitting portion is built in the main body side, a long shape can be realized. Since this flexible portion can be bent in all directions such as front, rear, up, down, left and right, there is no limitation on the irradiation direction unlike the conventional desk light, for example.

According to a second aspect of the present invention, the flexible section is also provided with a wire section which is also used as the current-carrying section and which holds the bent shape in the protective tube. In this way, by incorporating the wire, the wire is bent according to the force applied to the flexible part,
Since the bent shape is maintained, the flexible function of the flexible portion can be easily realized. Moreover,
Since this wire constitutes one of the current-carrying parts, it also has the effect of reducing the number of parts.

As another embodiment, as claimed in claim 3, at least two pairs of the flexible portion and the light emitting portion at the tip thereof are provided. With such a structure, it is possible to illuminate two or more different places at the same time, so for example, while illuminating a gap in a part of the machine and illuminating the whole machine while keeping the whole field of view Can be promoted, and workability can be improved. Alternatively, both pages of a two-page spread book can be illuminated. Further, in each of the portable lights, as described in claim 4, the power supply unit is provided with a condenser to which electric power is externally supplied. By using the capacitor in this way, it is possible to instantly store the necessary electric power, and it is possible to use the capacitor for a relatively long time with respect to the charging time.

Further, preferably, in each of the portable lights described above, as described in claim 5, the main body is provided with a fixing portion for external connection. By providing such a fixed portion for connection to the outside, it is possible to easily illuminate a desired place by moving only the flexible portion by hand. In the case of a conventional light, the light emitting part is fixed to the tip of the main body even if a similar external fixing part is provided, so if the irradiation direction is changed, the fixing position itself must be changed. Although inconvenient, the structure of the present claim makes it easy. Moreover, since it is not necessary to hold the light itself with one hand, both hands are free, and workability such as confirmation work and repair work is significantly improved.

As a preferred embodiment, as in claim 6, a clip structure capable of being pinched and fixed to the connection fixing portion from the outside, for example, a plate-like structure biased by a spring or the like to the main body portion. It is characterized by having. By using the clip in this way, for example, even in the case of nursing work of a nurse in a hospital at night, the nurse attaches the portable light to the chest pocket of clothes by a clip so that both hands can be used for nursing. Not only is it open, but you can also bend the light irradiation point by touching it lightly with your fingertips if necessary, and since it can be fixed as it is,
The work efficiency can be significantly improved.

According to a seventh aspect of the present invention, the fixed portion is
By providing holes that allow the fixed parts prepared according to the connection surface to be attached and detached, the fixed parts can be replaced for various external connection surfaces, and this portable light can also be used as a variety. It can be effectively used in work and on-site. As the fixed part, for example, a magnet or a suction plate can be used as in claim 8 or 9. For example, by using a magnet as a fixed part, at the time of repairing a car at night, etc., this flexible light is fixed to the back side of the opened bonnet or a part of the chassis, and the flexible part is bent as necessary. By illuminating the place, it is not necessary to hold the light with one hand, and workability is very good. Moreover, the setting and removal of the light itself is extremely easy because you only need to attach or remove the magnet. Further, if a suction plate is used as the fixed part, it is possible to fix the flat surface, which has a smooth connection surface, such as a window glass of an automobile.

Further, in the figure, reference numeral 15 is an alternation type switch portion, 16 and 17 are fixing parts used in combination with a fixing portion 14 for attaching the portable light according to the present invention to various places, 16 is a suction plate, and 17 is a magnet. have. Reference numeral 18 is a fixing sheet for improving the adhesiveness when it is attached to the outside. The fixing parts 16 and 17 are used by attaching their respective protrusions 16 ′ and 17 ′ to the fixing holes 141 provided in the fixing part 14. The fixing portion 14 is biased toward the main body portion 11 by the spring 142, and a curved groove portion 19 is formed between the fixing portion 14 and the main body portion 11.

Here, a power supply unit 111 as shown in FIG. 3 is built in the main body 11. As the power supply unit 111, for example, a battery or a capacitor can be used, but a capacitor is used here. Figure 4
3A shows a circuit configuration when a battery is used, and FIG. 3B shows a circuit configuration when a capacitor is used. In the figure, 112 is a resistor, 13 is the above-mentioned LED, and 15 is an alternate type switch unit. In addition, this power supply unit 111
Can be connected to an external power source (not shown) by an external connection terminal 113. In addition, the flexible portion 12 is shown in FIG.
As shown in FIG.
Energization cords 122 and 123 are built in the inside.
The one energizing cord 122 is made of wire and has the function of retaining the curved shape of the flexible portion 12 at the same time in addition to the energizing function. The other 123 is a cord whose surface is covered with an insulating resin (to electrically insulate the energizing cord 122). The energizing cord 122 is not limited to the wire as long as it can be electrically energized and has a flexible shape and can be fixed in shape, and may be a braided thin metal wire. As the light of the light emitting unit 13, an LED having high brightness and long light emission life is used.

The method of using the portable light 1 having the above structure is as follows.
First, the external connection terminal 113 is connected to an external power supply unit (not shown) for charging. A 9V battery, for example, is used as the power supply unit. After charging, the flexible light 1 is removed from the power supply unit 1 and used. In this state, it can be used as a normal light, but the characteristic usage of this portable light will be described below. FIG. 5 shows a state in which the portable light 1 is attached to the chest pocket 50 of clothes. At the time of attachment to the chest pocket 50, the fixing portion 14 of the portable light 1 shown in FIG. 1 is lifted in the direction away from the main body portion 11 and the gap is inserted in the pocket. Since the fixing portion 14 is biased toward the main body portion 11 by the spring 142, the pocket 50 is firmly sandwiched and the portable light 1 is fixed to the clothes. As a result, as shown in FIG. 5, the portable light 1 has a chest pocket 5
Light is emitted from the light emitting portion 13 which is fixed at 0 and extends from there through the flexible portion 12. 100
Indicates the irradiated portion. In this state, the user can easily orient the light emitting portion 13 in a desired direction by simply bending the flexible portion 12, and the flexible portion 12 is fixed in that direction, so that the user can work with both hands free. This is extremely useful because it can irradiate a necessary place at any time depending on the work content and work state.

Specifically, it is very convenient for a nurse to examine a patient (taking a pulse, measuring a body temperature, or performing an infusion) in a hospital at night. Conventionally, it is common to work with a flashlight etc. without turning on the lighting of the whole room so as not to wake up other patients, but having a flashlight in one hand makes it difficult to work, I used to put a flashlight on the bed side table, the patient's bedside, etc. to do the work. However, as work, in addition to medical examinations and infusions, there are things such as recording the results of medical examinations in a notebook, checking the materials about the patient, etc., and changing the irradiation direction each time by taking up a flashlight etc. It had to be done and was very inconvenient. In this respect, if this portable light is used, both hands are open with the light fixed in the chest pocket, and the light emitting portion 13 at the tip thereof is used.
As necessary, the patient can be irradiated with light by simply bending it toward the patient, or the note at hand, etc., and the irradiation direction of the light is fixed in that state,
Even in the case of continuous work, the light irradiation direction can be changed one after another, so that work efficiency is significantly improved. Also, in the case of removal, it is possible to easily remove it from the pocket simply by lifting the fixing portion 14 from the main body portion 11.

FIG. 6 is a view showing another example of use of the portable light according to the present invention. As shown in FIG. 6, the portable light 1 can be used by fixing it to the pipe portion 61 of the pipe bed 60. In this case, the fixing portion 14 of the portable light 1 is connected to the main body portion 1 in the same manner as described in the embodiment of FIG.
1 is lifted in a direction away from 1, and the groove portion 19 between the fixing portion 14 and the main body portion 11 is applied to the pipe portion 61, and is fixed by being sandwiched. Here, the groove portion 19 is provided with the fixing sheet 18 having excellent cushioning and fixing properties, and the fixing sheet 18 further improves the degree of fixing the portable light to the pipe 61. In this way, by equipping a part of the bed with the portable light, for example, in a bed of a patient in a hospital, the book light irradiates only a necessary portion, so that the patient can use his / her own light without disturbing other patients. Can be used for Moreover, since the irradiation direction can be easily changed and the irradiation direction of light can be fixed, it is excellent in usability.

FIG. 7 shows an example in which the portable light is used for the handle 70 of a bicycle or the like. Even in this case, as in each of the above embodiments, the light irradiation direction is set to 10 as shown in the figure.
It can be changed in any direction such as 0, 101, 102. Reference numerals 100 and 101 are used to assist a light normally provided on a bicycle and to illuminate a direction that cannot be illuminated by the light. However, in the case of 102, the presence of the bicycle is notified to a car behind the vehicle. It can also be used as a function to do.

FIG. 8 is a view showing a method of using a portable light according to still another embodiment, showing a case where the inside (80 in the drawing) of the automobile is checked by opening the hood of the automobile. In this case, first, a fixed part (magnet) is attached to the fixing hole portion 141 of the fixing portion 14 of the portable light 1 of FIG.
The protrusion 17 ′ of 17 is fitted and attached. As a result, the portable light 1 can be directly attached to a part of the chassis with the bonnet opened by using the magnet. Therefore, similar to the above, one hand is not occupied to illuminate with a flashlight as in the conventional case, which is very convenient. Moreover, since the irradiation direction can be easily determined only by moving the flexible portion 12 by hand, and the irradiation direction is fixed even if the hand is released, the workability is extremely excellent. Further, when the work is completed, the entire portable light 1 is merely fixed by the magnetic force, so that it can be easily separated.

In this embodiment, the magnet is used as the fixed part, but the present invention is not limited to this, and the attraction plate (see FIG.
16), it can be fixed to a place with a smooth surface. With this configuration, when used in a passenger car, for example, it can be used for confirming the map of the navigator by attaching it to the window of the passenger seat.

Although not shown, as another method of use, since the flexible portion 12 has a long shape, the flexible portion 12 may be provided with a gap between objects or a curved portion as needed. The light emitting portion provided at the tip can illuminate the gap or the back portion by pushing it along and bending. Further, a plurality of flexible portions 12 of the portable light 1 according to the present invention and a plurality of light emitting portions 13 at the tip thereof may be provided. With this structure, since there are a plurality of light emitting portions 13, for example, it is shown in FIG. When the nurse is pointing to one of the light emitting parts 13 in the direction of the document at hand while using it in the chest pocket,
It can be used such that the other light emitting unit 13 is directed toward the patient. It should be noted that the present invention is not limited to the above-described respective embodiments and usages, and it is needless to say that various improvements and changes may be made without departing from the gist of the present invention.

[0020]

As described above, according to the portable light of the present invention, the direction of the light emitting portion can be freely bent in all directions such as front, rear, up, down, left and right, and can be easily bent by a hand or the like, and the light emitting posture can be fixed. It is useful for, for example, nursing work of a nurse at night, as well as various confirmation and repair work. Furthermore, by using the external connection and fixing part, the operator has both hands free, which further improves workability.
