JP6788254B2 - How to control the amount of light emitted by tweezers and the illuminant of tweezers - Google Patents

Description

The present invention relates to tweezers, and more particularly to tweezers including a light emitter.

In the maintenance work of various electronic devices, dedicated terminals, etc., the work of replacing the internal parts of the device to be worked on may be performed. At that time, depending on the size of the device and the position where the part to be replaced is installed in the device, it may not be possible to secure a sufficient work space and the operator may not be able to reach it. In such a situation, the worker may work with tweezers.

Normally, the light of indoor lighting does not easily reach the inside of the equipment, and the inside of the equipment tends to be dark. For this reason, when working inside the device, it is necessary to illuminate the target object and its surroundings to be worked with tweezers by some means.

However, it is difficult to place the lighting equipment inside the equipment to be worked on. In addition, if the lighting equipment is placed outside the equipment, the light may be blocked by the worker's own body. It is conceivable that the operator himself holds the hand light in one hand to illuminate the inside of the device while holding the tweezers in the other hand, but such a method is difficult and has low workability. ..

There are tweezers equipped with a light source so that the user can work while illuminating the work space with one hand.

The tweezers of Patent Document 1 include two arms and a proximal end. The base end connects the arms in a bifurcated manner. The arm portion has a light emitting portion, a light guide portion, and a tip portion, respectively. The light emitting portion is provided on the base end side of the arm portion. The light emitted by the light emitting unit is emitted from the tip portion toward the outside of the arm portion via the light guide portion.

Patent Document 2 discloses a keyhole lighting device. The keyhole lighting device includes two L-shaped operating rods. Each L-shaped operating rod is provided with a light emitting diode at the tip.

Japanese Unexamined Patent Publication No. 2007-06937 Utility Model Registration No. 3100346

In each of the tweezers and the keyhole lighting device described in Patent Documents 1 and 2, the light source can be turned on and off, but the amount of light cannot be adjusted. Therefore, these light sources always irradiate a uniform amount of light.

Generally, tweezers are used to pick up various objects. Some objects have a surface that easily reflects light. On the contrary, some objects have a surface that does not easily reflect light. If the target object is irradiated with a certain amount of light without considering the strength of the reflection, the target object may be difficult to see because the reflected light is too strong or too weak.

The present invention has been made in view of such a situation, and an object to be solved by the present invention is to provide tweezers in which the amount of light of a light source can be adjusted.

In order to solve the above problem, the present invention provides, as one aspect, of the two arm portions, and the light amount adjusting means for controlling the light emitters disposed on at least one of the tip, the light emission amount of the light emitter When the tips of the two arms are in contact with each other, the power of the light emitter is turned off, and when the tips of the two arms are separated from each other, the light emitter Provided is a tweezers with a power switch to turn on the power .

Further, as another aspect of the present invention, a light emitting body arranged at at least one tip of the two arms, a light amount adjusting means for controlling the light emitting amount of the light emitting body, and a light amount adjusting means .
A power switch for turning on / off the power of the light emitting body is provided on the tweezers, and the light emitting amount of the light emitting body is controlled by the light amount adjusting means. In the power switch, the tips of the two arms are in contact with each other. Provided is a method of turning off the power of the light emitting body and turning on the power of the light emitting body when the tips of the two arms are separated from each other .

According to the present invention, it is possible to adjust the amount of light emitted from the light emitting body provided at the tip of the tweezers and perform the work with an appropriate amount of light according to the work space.

(First Embodiment)
The tweezers 100, which is the first embodiment of the present invention, will be described. Referring to FIG. 1, the tweezers 100 includes a base 1 and an arm 2. The arm portion 2 is composed of two arm portions 2L and 2R, and the arm portions 2L and 2R extend from the base portion 1 in a bifurcated shape. The base 1 includes a light amount adjusting unit 4, a power switch 5, and a power source 6. The arm portion 2L includes a tip portion 21L and a lead wire 22L. The tip portion 21L includes a light emitting portion 23L. Similarly, the arm portion 2R includes a tip portion 21R and a lead wire 22R. The tip portion 21R includes a light emitting portion 23R.

The base 1 supports the arms 2L and 2R as cantilever beams, respectively. Further, the base portion 1 houses a light amount adjusting unit 4, a power switch 5, and a power supply 6 inside. The base 1 is a hollow tubular housing made of, for example, metal, plastic, or the like. The base 1 houses a light amount adjusting unit 4, a power switch 5, and a power source 6 inside. Further, at the end portion of the base portion 1, the arm portions 2L and 2R are supported as cantilever beams, respectively. The base 1 may have a solid plate shape. In that case, the light amount adjusting unit 4, the power switch 5, and the power supply 6 are arranged on one side or both sides of the plate.

The arms 2L and 2R are cantilever beams made of elastic materials such as metal and plastic, respectively. One end of each of the arms 2L and 2R is supported by the base 1, and the other ends are the tips 21L and 21R, respectively. The operator using the tweezers 100 holds the base 1 with the middle finger, the ring finger and the little finger so as to sandwich the arms 2L and 2R between the thumb and the index finger. When the space between the thumb and index finger is narrowed, the tips 21L and 21R approach each other. When the tweezers 100 are operated so that the target object is located between the tip portions 21L and 21R, the target object can be sandwiched between the tip portions 21L and 21R by narrowing the space between the thumb and the index finger.

The tip portions 21L and 21R have holding surfaces 24L and 24R facing inward of the arm portions 2L and 2R, respectively. The sandwiching surfaces 24L and 24R may be smooth flat surfaces. Alternatively, in order to prevent the sandwiched object from slipping, a large number of fine irregularities may be provided on the flat surface. Alternatively, it may be a curved surface having a recess in a shape along the outer shape of the object to be sandwiched.

Lead wires 22L and 22R are embedded in the arms 2L and 2R, respectively. The lead wire 22L electrically connects between the light amount adjusting unit 4 and the light emitting unit 23L, which will be described later. Similarly, the lead wire 22R electrically connects the light amount adjusting unit 4 and the light emitting unit 23R.

The light emitting units 23L and 23R convert the current supplied through the conducting wires 22L and 22R into light. The light emitting units 23L and 23R are, for example, LEDs (Light Emitting Diodes). The light emitting units 23L and 23R are not limited to LEDs, and the light emitting principle is not particularly limited as long as they convert electric power into light. The light emitting units 23L and 23R may be, for example, light bulbs. Hereinafter, the light emitting bodies that can be used as the light emitting units 23L and 23R are collectively referred to as a light emitting body. Each of the light emitting units 23L and 23R includes at least one light emitting body. The light emitting units 23L and 23R may each include a plurality of light emitting bodies.

The light emitting unit 23L is preferably arranged so that the optical axis 25L is substantially perpendicular to the sandwiching surface 24L, for example. In other words, in the plane including the longitudinal directions 26L and 26R of the arms 2L and 2R (for example, the paper surface of FIG. 1), the optical axis 25L is substantially perpendicular to the longitudinal direction 26L of the arms 2L. It is preferable that the light emitting unit 23L is arranged. The same applies to the optical axis 25R of the light emitting unit 23R.

FIG. 2 illustrates an example of the light emitting unit 23L. FIG. 2 shows a state in which the light emitting portion 23L is viewed from a direction perpendicular to the holding surface 24L. In the light emitting unit 23L of this example, one LED is embedded in the sandwiching surface 24L made of a smooth flat surface. The same applies to the light emitting unit 23R that is a pair of the light emitting unit 23L.

With such an arrangement of the optical axis, when the tweezers 100 are operated so that the target object is between the tip portions 21L and 21R, the light of the light emitting portions 23L and 23R can illuminate the target object from both side surfaces. Therefore, for example, when working in a dark part in the apparatus housing, the operator can easily visually recognize the target object until immediately before the target object is lifted by using the tweezers 100.

Consider a tweezers whose optical axis is oriented in a direction parallel to the holding surfaces 24L and 24R (arms 2L and 2R in the longitudinal direction 26L and 26R). Immediately before grasping the target object with tweezers, the target object is located between the tip portions 21L and 21R. In this positional relationship, the light along the optical axis does not go toward the target object. Light along the optical axis travels along the longitudinal directions 26L and 26R. For this reason, the target object and its surroundings become dark immediately before the target object is picked up by the tweezers.

The power source 6 supplies electric power for the light emitting units 23L and 23R to emit light. The power supply 6 may have a built-in battery such as a button battery or a secondary battery. Instead of providing an internal power source such as a battery in the base 1, a power port for connecting to an external power source may be provided in the base 1 as a power source 6. For example, a USB (Universal Serial Bus) port may be provided on the base 1 as a power source 6, and power may be supplied from an external power source (not shown) via a USB cable (not shown).

The power switch 5 is a switch for turning on / off the power supply from the power source 6 to the light amount adjusting unit 4, the conducting wires 22L and 22R, and the light emitting units 23L and 23R.

The light amount adjusting unit 4 is a circuit for adjusting the amount of light emitted by the light emitting units 23L and 23R. The light amount adjusting unit 4 includes means for receiving the designation of the light amount by the operator. For example, a changeover switch for switching the amount of light into three stages of weak, medium, and strong may be provided. The operator switches the changeover switch with a finger or the like. Alternatively, when the power supply 6 receives power from an external power source via a USB cable or the like, the specified light amount may be input to the light amount adjusting unit 4 via the USB cable.

By providing the light amount adjusting unit 4, the operator can adjust the amount of light emitted by the light emitting units 23L and 23R according to the brightness of the work space, the degree of reflection of light on the target object, and the like. As a result, the worker can perform the work with an amount of light that makes it easy for him / her to see the target object or the like.

When the light emitting body is an LED, the light amount adjusting unit 4 may be a current control circuit that controls the magnitude of the current. That is, the brightness of the LED may be controlled by the supplied current value. In this case, the number of LEDs may be one or a plurality.

When the light emitting body is an LED, the light amount adjusting unit 4 may be a pulse width modulation circuit that modulates the pulse width. That is, the amount of light emitted from the LED may be adjusted by repeating on / off of a constant current in a short time and changing the length of time (pulse width) of turning on in one cycle of on / off. In this case, the number of LEDs may be one or a plurality.

Further, when the light emitting units 23L and 23R are each composed of a plurality of light emitting bodies, the light amount adjusting unit 4 may be a light emitting body selection circuit that selectively emits a part or all of the plurality of light emitting bodies. In such a light amount adjusting unit 4, instead of changing the light emitting amount of each light emitting body, the light emitting amount is adjusted by changing the number of light emitting bodies. The light emitter may be an LED or another light emitter.

For example, as shown in FIG. 3, it is assumed that the light emitting unit 23L includes three LEDs, 23L1, 23L2, and 23L3. The optical axes of the LEDs 23L1, 23L2, and 23L3 are substantially perpendicular to the holding surface 24L, respectively. At this time, the light amount adjusting unit 4 selects one of the following (1) to (3). (1) Only LED23L2 is turned on, and LEDs 23L1 and 23L3 are turned off. (2) Only LED23L2 is turned off, and LEDs 23L1 and 23L3 are turned on. (3) Turn on all of LEDs 23L1, 23L2, and 23L3. As a result, the amount of light is changed in three stages according to the number of LEDs to be emitted.

According to the tweezers 100 of the present embodiment, since the light amount adjusting unit 4 is provided, the operator can perform the tweezers work with a desired amount of light.

(Second Embodiment)
The tweezers 200, which is the second embodiment of the present invention, will be described. Compared with the above-mentioned tweezers 100, it is different in that the power switches 5L and 5R are provided instead of the power switch 5.

This will be described with reference to FIG. The power switches 5L and 5R are a set of switches. However, the power switches 5L and 5R are turned on when they are separated from each other. At this time, the light emitting units 23L and 23R are turned on. On the other hand, the power switches 5L and 5R are turned off when they are in contact with each other. At this time, the light emitting units 23L and 23R are turned off. In FIG. 4, the power switches 5L and 5R are turned on because they are separated from each other. Both the light emitting units 23L and 23R are lit.

Further, the tweezers 200 includes a binding tool 7. The binding tool 7 is a means for binding the arms 2L and 2R. When the arms 2L and 2R are bound by the binding tool 7, the power switches 5L and 5R maintain their contact with each other. The binding tool 7 may be, for example, a string made of natural fibers or synthetic fibers, or a band made of plastic, rubber, or the like. These strings and band-shaped binding tools 7 are separable from the arms 2L and 2R. However, the binding tool 7 is not limited to such a form. If the power switches 5L and 5R can be maintained in contact with each other, the binding tool may be provided in an inseparable form from the arm portions 2L and 2R and the base portion 1.

FIG. 5 shows how the rubber band is used as the binding tool 7. Since the binding tool 7 keeps the power switches 5L and 5R closed, both the light emitting units 23L and 23R are turned off at this time.

According to the tweezers 200, if the operator removes the binding tool 7 before the start of the tweezers work, the power switches 5L and 5R are separated from each other. As a result, the light emitting units 23L and 23R are turned on. Further, when the operator binds the arms 2L and 2R with the binding tool 7 after the tweezers work is completed, the power switches 5L and 5R come into contact with each other. As a result, the light emitting units 23L and 23R are turned off. Therefore, the operator does not need to operate the power switch for the purpose of causing the light emitting units 23L and 23R to emit light.

Although the present invention has been described above according to the embodiment, the present invention is not limited thereto. For example, in the above-described embodiment, the light emitting portions are provided at the tips of both of the two arms, but the present invention is not limited to this, and only the tip of one of the arms is provided.
