JP-A-2002-346951

However, since the inside of the magazine is shaded by the wall covering the magazine, there is a problem that it is dark and difficult to work.

For example, in the case of a tacker as described in Patent Document 1, if the magazine is opened while the remaining consumables are low, the remaining consumables may fall down in the magazine. If the visibility in the magazine is poor, new consumables may be loaded without noticing that the consumables have fallen, causing blank shots and needle clogging. Further, even when a needle is clogged, there is a problem that it is difficult to remove the needle if the visibility in the magazine is poor.

Therefore, it is an object of the present invention to provide a portable power drive tool that improves the visibility in the magazine and facilitates operations such as loading consumables.

The present invention has been made to solve the above-mentioned problems, and is characterized by including a magazine for loading consumables and a light source for illuminating the inside of the magazine.

As described above, the present invention includes a light source that illuminates the inside of the magazine, so that the visibility inside the magazine can be improved. Therefore, even if the consumables fall down in the magazine, it is easy to notice the fallen consumables and to stand up the fallen consumables. Further, even if the needle is clogged, the needle removal work can be easily performed.

It is a partially enlarged perspective view of the power tool which opened the magazine, and is the figure which shows the inside of a magazine. It is a partially enlarged perspective view of the power tool which opened the magazine of the power tool which concerns on modification 1, and is the figure which shows the inside of the magazine. It is a perspective view of the power tool which concerns on modification 2. FIG. It is a side view of the power tool which concerns on modification 2. FIG.

An embodiment of the present invention will be described with reference to the drawings. In the following description, as a portable power drive tool, an electric tool 10 (driving tool) that ejects a fastener (a U-shaped staple needle in the present embodiment) from an injection port 20a will be described as an example. However, the power tool 10 is only an example, and the present invention can be similarly applied to a driving tool driven by compressed air, a driving tool driven by burning flammable gas, and the like.

As shown in FIG. 1, the power tool 10 according to the present embodiment is covered with a housing 11. The power tool 10 includes an output unit 20, a grip 21, a magazine 23, a motor accommodating unit 24, and a battery mounting unit 25.

The output unit 20 is a portion that houses a driver (not shown) for punching out the fastener. The driver is slidable in the longitudinal direction of the output unit 20. An injection port 20a is opened at the tip of the output unit 20, and a fastener before launching stands in front of the injection port 20a. When the trigger 22 described later is operated and the driver slides in the direction of the injection port 20a, the fastener waiting in front of the injection port 20a is ejected from the injection port 20a by the driver and is driven into the material to be driven. ing.

The grip 21 is a rod-shaped portion that the operator grips when using the power tool 10. The grip 21 is connected so as to be substantially orthogonal to the output unit 20. Specifically, the grip 21 is connected to the rear side of the output unit 20 when the output unit 20 is viewed in the launch direction of the fastener. The grip 21 is provided with a trigger 22 for operating the power tool 10. The trigger 22 is arranged at a position where the index finger rests when the operator grips the grip 21. When the operator pulls the trigger 22, the micro switch (not shown) built in the grip 21 is turned on. When the micro switch is turned on, an electric signal is transmitted to the control board, the motor is driven and controlled by the control board, the electric tool 10 is operated, and the fastener is driven.

The magazine 23 is a part for loading the connecting fastener 40 as a consumable item. In the present embodiment, as shown in FIG. 2, a connecting fastener 40 in which fasteners (staple needles) formed in a substantially U shape are connected in a rod shape can be loaded into the magazine 23. The magazine 23 is connected so as to be substantially orthogonal to the output unit 20, and is arranged substantially parallel to the grip 21. Specifically, the magazine 23 is connected to the front side of the output unit 20 when the output unit 20 is viewed in the ejection direction of the fastener. The tip of the magazine 23 communicates with the output unit 20 internally, and a fastener can be supplied to the tip of the output unit 20 (near the injection port 20a).

The motor accommodating portion 24 is provided adjacent to the magazine 23 and accommodates the motor. The motor is a drive source for operating the power tool 10. In the present embodiment, the rotation of the motor causes the driver to perform a driving operation and the driver to return to the standby position.

The battery mounting portion 25 is a portion for making the battery pack 26 removable. The battery mounting portion 25 is provided at the lower end of the grip 21 (the end opposite to the output portion 20). In other words, the output unit 20 is connected to one end of the grip 21, and the battery mounting unit 25 is connected to the other end.

In the present embodiment, the battery pack 26 can be slid and attached / detached to the lower surface of the battery mounting portion 25. Although not particularly shown, a latch is provided on the upper surface of the battery pack 26 so as to be retractable, and the battery pack 26 is attached to the power tool 10 by engaging the latch with the lower surface of the battery mounting portion 25. When the battery pack 26 is attached to the power tool 10, the battery pack 26 and the power tool 10 are electrically connected, and the electric power stored in the battery pack 26 can be used by the power tool 10.

The battery mounting portion 25 has a built-in control board for controlling the operation of the power tool 10.

By the way, as shown in FIG. 2, the magazine 23 according to the present embodiment is formed in a square tubular shape. The magazine 23 includes an opening / closing portion 32 that covers the front surface (the surface facing the material to be driven when the fastener is driven). The opening / closing unit 32 is slidable with respect to the magazine 23, and the inside of the magazine 23 can be opened / closed by sliding the opening / closing unit 32.

When the opening / closing portion 32 is slid to open the inside of the magazine 23, the inner surface of the magazine 23 is exposed as shown in FIG. A second window portion 31 for emitting light is provided on the inner surface of the magazine 23. In the present embodiment, the second window portion 31 is provided on the inner surface facing the opening / closing portion 32. The second window portion 31 is covered with a transparent or translucent cover so that light emitted from behind can be transmitted or diffused.

Next to the second window portion 31, as shown in FIG. 3, a first window portion 30 is provided. Like the second window portion 31, the first window portion 30 is arranged so as to face the material to be driven when the fastener is driven. In the present embodiment, the first window portion 30 and the second window portion 31 are arranged on the same plane with the wall of the magazine 23 interposed therebetween.

Although not particularly shown, a light source such as an LED is arranged on the back side of the first window portion 30 and the second window portion 31. The light from this light source passes through the first window portion 30 and the second window portion 31 and is irradiated to the inside and the outside of the magazine 23. In other words, the first window portion 30 and the second window portion 31 are both window portions for emitting light from the same light source. However, the first window portion 30 is for illuminating the tip direction of the tool with the light of the light source, and is arranged outside the magazine 23. On the other hand, the second window portion 31 is for illuminating the inside of the magazine 23 with the light of the light source, and is arranged inside the magazine 23.

The above-mentioned light source is turned on when a predetermined opportunity is achieved, such as when a predetermined switch is turned on. When the light source is turned on, the light of the light source passes through the first window portion 30 and is irradiated to the outside to illuminate the vicinity of the consumable driving position (near the extension line of the injection port 20a). This makes it easier to work even when the driving position is dark. Further, when the light source is turned on, the light of the light source passes through the second window portion 31 and is irradiated into the magazine 23. As a result, the inside of the magazine 23 is illuminated, and the work becomes easy even when the inside of the magazine 23 is dark.

Although not particularly shown, a dedicated switch that can be operated by an operator may be provided in order to turn on the light source.

Further, the switch for turning on the light source may be turned on in association with other operations. For example, when the magazine 23 is opened (when the opening / closing unit 32 slides into the open state), the switch may be turned on and the light source may be turned on.

Further, when loading the connecting fastener 40, the light intensity of the light source may be lowered because it is dazzling if the light source is too strong. For example, the light source may emit light at a lower luminous intensity when the opening / closing portion 32 is in the open state than when the opening / closing portion 32 is in the closed state. In this way, when the opening / closing portion 32 is in the open state (during the loading operation of the connecting fastener 40), the light is weakened, so that the inside of the magazine 23 is not dazzling. Further, since the light becomes stronger when the opening / closing portion 32 is in the closed state, the driving position can be sufficiently brightly illuminated.

Further, the light source is configured to change its direction depending on the open / closed state of the open / close portion 32, and when the open / close portion 32 is in the closed state, light is emitted toward the first window portion 30, and when the open / close portion 32 is in the open state. , The light may be emitted toward the second window portion 31. For example, the direction of the light source may be changed mechanically in conjunction with the opening and closing of the opening / closing unit 32. In this way, when the opening / closing portion 32 is in the open state (during the loading operation of the connecting fastener 40), the inside of the magazine 23 can be irradiated to brighten the inside. Further, when the opening / closing portion 32 is in the closed state, the driving position can be irradiated. Further, a light guide member for introducing the light of a light source such as an LED into the magazine 23 may be provided so that the direction of the light guide member changes depending on the open / closed state of the opening / closing portion 32.

As described above, according to the present embodiment, since the light source that illuminates the inside of the magazine 23 is provided, the visibility inside the magazine 23 can be improved. Therefore, even if the consumables fall down in the magazine 23, it is easy to notice the fallen consumables and to stand up the fallen consumables. Further, even if the needle is clogged, the needle removal work can be easily performed.

Further, as a window portion that emits the light of the light source, a first window portion 30 and a second window portion 31 are provided, and the first window portion 30 illuminates the tip direction of the tool by the light of the light source. The second window portion 31 is arranged inside the magazine 23 in order to illuminate the inside of the magazine 23 by the light of the light source. With such a configuration, one light source can be used for two different purposes. Therefore, it is possible to improve the visibility in the magazine 23 with a simple structure in which the number of parts is reduced.

By the way, in the above-described embodiment, one light source illuminates both the inside and the outside of the magazine 23, but the present invention is not limited to this, and two or more light sources may be provided. For example, as shown in FIG. 4, a magazine light source 33 such as an LED may be arranged inside the magazine 23. Then, apart from the magazine light source 33, an irradiation light source that illuminates the tip direction of the tool may be provided. The irradiation light source is arranged on the back side of the first window portion 30. Therefore, when the irradiation light source is turned on, the light of the irradiation light source irradiates the tip direction of the tool through the first window portion 30. Even in this case, the magazine light source 33 that illuminates the inside of the magazine 23 can improve the visibility inside the magazine 23. Since the magazine light source 33 and the irradiation light source can be individually controlled to be lit, it is not necessary to turn on the irradiation light source during the loading operation, and the irradiation light source is not dazzling. In the example shown in FIG. 4, the second window portion 31 is provided, but when the magazine light source 33 is provided, the second window portion 31 may not be provided.

The magazine light source 33 described above may be attached to the slideable opening / closing portion 32, or may be attached to the inner wall portion of the magazine 23.

Further, the magazine light source 33 and the irradiation light source may be controlled to be lit by the same specific switch. That is, both the magazine light source 33 and the irradiation light source may be turned on when a specific switch is turned on. However, the magazine light source 33 and the irradiation light source do not necessarily have to be turned on when the switch is turned on, and may be turned on only when a specific condition is satisfied.

For example, the above-mentioned irradiation light source may not be lit when the opening / closing unit 32 is in the open state, and may be lit when the opening / closing unit 32 is in the closed state. That is, if the opening / closing unit 32 is in the open state when the switch is turned on, the irradiation light source may not be turned on, and if the opening / closing unit 32 is in the closed state, the irradiation light source may be turned on. With this configuration, the irradiation light source is turned off when the opening / closing portion 32 is in the open state (during the loading operation of the connecting fastener 40), so that the operator during the loading operation does not feel the irradiation light source dazzling. .. Further, when the opening / closing portion 32 is in the closed state, the driving position can be irradiated by the irradiation light source. Further, since the light source for irradiation does not light when the opening / closing part 32 is not closed firmly, the operator can easily notice that the opening / closing part 32 is not closed, and the opening / closing part 32 is not completely closed before driving. You can prevent mistakes.

Further, the above-mentioned magazine light source 33 may be turned on when the opening / closing part 32 is in the open state, and may not be turned on when the opening / closing part 32 is in the closed state. With this configuration, the inside of the magazine 23 can be illuminated and brightened only when the opening / closing portion 32 is in the open state (during the loading operation of the connecting fastener 40).

In the above embodiment, the magazine light source 33 and the irradiation light source are controlled to be turned on and off, but the present invention is not limited to this, and the light from the magazine light source 33 or the light from the irradiation light source is physically used. A shielding member for shielding may be provided to operate the shielding member. Even with such a configuration, it is possible to substantially switch the light source on and off.

In the above-described embodiment, the tool provided with the straight rod-shaped magazine 23 has been described, but the present invention is not limited to this, and as shown in FIG. 5, in the tool provided with the cylindrical magazine 23, the magazine 23 A light source that illuminates the inside may be provided. In the example shown in FIG. 5, a lighting device 34 is provided at the rear end of the grip 21 (the end opposite to the output unit 20), and a light source such as an LED is mounted on the lighting device 34. This light source is arranged so as to illuminate the inside of the magazine 23 when the inside of the cylindrical magazine 23 is opened. Even with this configuration, the light source that illuminates the inside of the magazine 23 can improve the visibility inside the magazine 23.

Further, the tool provided with such a cylindrical magazine 23 sends the connecting nail wound in a coil shape to the nose portion 35 in which the nail ejection port 20a is formed. A door 37 that can be opened and closed is attached to the nose portion 35. By opening the door 37, as shown in FIG. 6, the nail feeding path 36 from the magazine 23 to the nose portion 35 and the inside of the nose portion 35 can be opened. Therefore, if the lighting device 34 illuminates not only the inside of the magazine 23 but also the inside of the nail feeding path 36 and the nose portion 35, the nail loading work and the nail clogging removing work can be easily performed. In this case, the lighting of the lighting device 34 may be linked not only to the opening and closing of the magazine 23 but also to the opening and closing of the door 37.
