  Therefore, the present invention has been made in view of the above points, and in a driving tool having an illumination device that performs a driving operation of a driving material such as a nail on a workpiece and irradiates a driving region of the driving material. It is an object of the present invention to provide a technique effective for improving operability.

  In order to achieve the above object, the invention described in each claim is configured. In the present invention, typically, various types of operations such as a nailing machine and a tucker are used to drive a workpiece by a driving material by linearly operating an operating member by the elastic force of a coil spring. It is a technique that can be applied to tools.

(First invention of the present invention)
A first invention of the present invention that solves the above-described problem is a driving tool according to claim 1.
The driving tool of the present invention is a driving tool for driving a driving material into a workpiece, and includes at least a driving device, a hand grip, a trigger, an operation member, a lighting device, and a lighting switch. The
The drive device of the present invention is configured as a device that applies a driving force to the driving material, and serves as a driving source for the driving material. As this drive device, a motor, a compressed air supply device, or the like is used. As the driving material, it is possible to use a straight rod having a pointed tip, a head having a cap or not, a U-shaped staple or the like.
The trigger according to the present invention is configured as a member that starts driving of the drive device by being pulled by an operator who holds the handgrip according to the present invention.
The operating member of the present invention is configured as a member that can be set to a first position where the trigger pulling operation is disabled and a second position where the pulling operation is enabled. When the operator pulls the trigger after the operating member is set at the second position, the driving device starts to be driven and the driving material is driven. As the operation member, a rotary lever, a slide switch, a push button, or the like can be used.

  The illuminating device of the present invention is configured as a device for irradiating a driving region of a driving material. The irradiation by the lighting device is started by the lighting switch of the present invention. In particular, the illumination switch of the present invention is configured to be turned on when the operation member is set from the first position to the second position when the trigger is pulled. With regard to this configuration, the illumination switch may be turned on based on the operation of setting the operation member from the first position to the second position, and the operation member and the illumination switch may be separate components. Alternatively, the operation member itself may be used as a lighting switch.

  According to such a configuration of the driving tool according to claim 1, since the illumination switch is turned on based on the operation of setting the operation member to the second position, the operation of irradiating the illumination device is individually performed. There is no need to do it. Therefore, it is possible to construct a driving tool that is easy to use and has high operability. At this time, the operation member is operated prior to the pulling operation of the trigger, and the actual driving material is driven after the illumination device is in the irradiation state. This is effective for surely aligning the position of the driving material to the part.

(Second invention of the present invention)
A second invention of the present invention that solves the above problem is a driving tool according to claim 2.
The driving tool according to the present invention is configured to further include a biasing means for biasing the operation member to the first position. The operation member is set from the first position to the second position against the urging force of the urging means when the trigger is pulled, and the illumination switch is turned on. On the other hand, the operation member is configured to return to the first position according to the urging force of the urging means by releasing the trigger pulling operation, and the illumination switch is turned off.

  According to such a configuration of the driving tool according to claim 2, when the operator is willing to drive and the operation member is set to the second position, the lighting device is set based on the setting. However, when the operator does not intend to drive and the operating member returns to the first position, the illumination device is released from the irradiation based on the setting. It is reasonable to save power.

(Third invention of the present invention)
A third invention of the present invention that solves the above problem is a driving tool according to claim 3.
The driving tool according to the present invention has the configuration described in claim 1 or claim 2 in the case where the handgrip is viewed by the operator from the worker side when the driving material is driven. The direction of the line of sight toward the worker's driving area and the direction of illuminating the driving area of the lighting device are configured to substantially overlap. Such a configuration is realized particularly by devising the position of the lighting device.

  According to such a configuration of the driving tool of the third aspect, when the driving material is driven, when the worker views the driving area, the illumination device is irradiated from the direction in which the worker can easily see. Therefore, it is difficult to form a shadow around the driving material in the driving region, which is effective in facilitating the driving operation.

  According to the present invention, in the driving work tool having the lighting device that performs the driving work of the driving material such as a nail on the work material and irradiates the driving region of the driving material, the operation of starting the irradiation of the lighting device in particular is performed. Further, it is possible to improve the operability by performing the operation based on the setting of the operation member that enables the trigger pulling operation.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. In the present embodiment, a rechargeable pin tacker will be described as an example of the “driving work tool” in the present invention. FIG. 1 is a side sectional view showing an overall configuration of a rechargeable pin tacker 100 according to an embodiment of the present invention, and FIG. 2 is a diagram showing a sectional structure taken along line AA of the rechargeable pin tacker 100 in FIG. . FIG. 3 is an enlarged cross-sectional view showing a configuration of a main part of the rechargeable pin tacker 100 in FIG.

As shown in FIGS. 1 and 2, the pin tacker 100 according to the present embodiment generally includes a main body 101 that forms an outer shell of the pin tacker 100, a battery case 109 that houses a battery, and a cover. It is mainly composed of a magazine 111 loaded with pins as driving materials to be driven into the workpiece. The main body 101 includes a motor housing 103 that accommodates the drive motor 113, a gear housing 105 that accommodates the driving mechanism 117 and the hammer drive mechanism 119, and a hand grip 107 that is gripped (gripped) by the operator ("hand grip in the present invention" ”). A hand grip 107 is disposed above the motor housing 103, a gear housing 105 is disposed at one horizontal end (the right side in FIG. 1) of the motor housing 103 and the hand grip 107, and a battery case 109 is disposed at the other horizontal end. Be placed. A magazine 111 is disposed below the motor housing 103 and the gear housing 105. The main body 101 has a configuration in which a handgrip 107 is attached to a long gear housing 105 that accommodates at least the driving mechanism 117, and the main body 101 corresponds to a “main body” in aspect 1 described later. Further, the driving mechanism 117 corresponds to a “driving mechanism” in aspect 1 described later, and the gear housing 105 corresponds to a “housing” in aspect 1 described later. The hand grip 107 extends in a long shape in a direction intersecting the gear housing 105 while being separated from a housing end portion on the opposite side of the pin driving region among the portions of the gear housing 105.
The magazine 111 is configured to supply the pins to be driven to the lower end portion of the gear housing 105, that is, the pin injection portion 112 provided at the distal end portion of the main body portion 101.

  As shown in FIG. 3, the driving mechanism 117 includes a rod-shaped slide guide 121 that extends linearly in the vertical direction and has an upper end portion and a lower end portion fixed to the gear housing 105, and a cylindrical shape on the slide guide 121. A hammer 125 mounted so as to be movable up and down via a slider 123, a compression coil spring 127 that applies a resilient force to the hammer 125 so as to drive the hammer 125 downward, and a hammer 125 that is moved and injected. Mainly composed of a driver 129 that applies a striking force (giving a striking force) to a pin as a driving material supplied to the pin driving port 112a of the portion 112 and thereby drives the pin into the workpiece. Has been.

  Here, the compression coil spring 127 according to the present embodiment is compressed to accumulate the elastic force, and the compression coil spring 127 in which the elastic force is accumulated freely expands to release the elastic force. It is a coil spring of composition. The compression coil spring 127 is also referred to as “compression coil spring”. Further, the hammer 125 and the driver 129 in the present embodiment constitute an operating member that operates linearly by a free extension operation of the compression coil spring 127 in which the elastic force is accumulated.

  The hammer 125 and the driver 129 are connected by a connecting pin 131. The hammer 125 has an upper engagement protrusion (engagement protrusion 125a in FIGS. 2 and 3) and a lower engagement protrusion (engagement protrusion 125b in FIG. 2). The upper engaging protrusion 125a is configured to engage with the upper lift roller (lift roller 137 in FIG. 2) of the hammer drive mechanism 119 and push it upward. The lower engaging protrusion 125b is configured to be engaged with a lower lift roller (lift roller 139 in FIGS. 2 and 3) of the hammer drive mechanism 119 and pushed upward. The pin as the driving material is in the form of a straight bar with a sharpened tip, and a pin having or not having a shade on the head is used. For convenience, illustration of pins and workpieces is omitted.

  The rotational output of the drive motor 113 is transmitted as a rotational motion to the hammer drive mechanism 119 via the planetary gear type reduction mechanism 115. As shown in FIGS. 2 and 3, the hammer drive mechanism 119 includes upper and lower gears 133 and 135, which are meshed and engaged with each other and rotated in opposite directions within the vertical plane, and lower gears 133 and 135. The upper and lower lift rollers 137 and 139 (see FIG. 2) that push the hammer 125 upward in accordance with the rotational movement of 135 are mainly configured.

  The gears 133 and 135 are rotatably mounted on a frame 134 disposed in the gear housing 105 via shafts 133a and 135a. The lift rollers 137 and 139 are rotatably mounted via support shafts 137a and 139a at positions eccentric from the rotation centers of the gears 133 and 135, and circularly move around the centers of the gears 133 and 135 as the gears 133 and 135 rotate. To do. In the present embodiment, the amount of eccentricity of the upper lift roller 137 from the support shaft 137a is equal to the amount of eccentricity of the lower lift roller 139 from the support shaft 139a. The lower gear 135 is meshed with and engaged with a drive gear 115b formed on the output shaft 115a of the speed reduction mechanism 115, and is driven to rotate at a predetermined speed reduction ratio. The gear ratio of the lower gear 135 and the upper gear 133 is set to 1: 1. Further, the lower lift roller 139 and the upper lift roller 137 are arranged to have a phase difference of about 180 degrees. The upper and lower lift rollers 137 and 139 are positioned farthest from each other, that is, the lower lift roller 139 is placed at the lower position of the lower gear 135, and the upper lift roller 137 is placed above the upper gear 133. This state (the state shown in FIG. 2) is the initial position.

  When the drive motor 113 is energized and the upper and lower gears 133, 135 are rotated in the direction of the arrow in FIG. 2, the lower lift roller 139 engages with the lower engaging protrusion 125 b of the hammer 125 from below. Circular movement is performed upward, and the hammer 125 is pushed upward by a vertical component of the circular movement. When the push-up amount of the hammer 125 by the lower lift roller 139 reaches near the maximum, the upper lift roller 137 engages with the engagement protrusion 125a of the upper portion of the hammer 125 from below and circularly moves upward, Push the hammer 125 upward.

  Thus, the hammer 125 is moved from the bottom dead center (pin driving end position, which corresponds to the initial position) to the upper side, that is, the top dead center side via the relay between the upper and lower lift rollers 137, 139. The compression coil spring 127 is compressed by the upward movement operation of 125, and the elastic force is accumulated. In the vicinity of the top dead center, the engagement protrusion 125 a on the upper portion of the hammer 125 is further transferred from the upper lift roller 137 to the cam 140. When the driver 129 is moved upward together with the hammer 125, the pins loaded in the magazine 111 are supplied to the pin driving port 112a of the injection unit 112. Thereafter, at the same time as the engagement with the cam 140 is released, the hammer 125 is driven downward by the elastic force of the compression coil spring 127. As a result, the pins supplied to the pin driving port 112 a of the injection unit 112 are driven into the workpiece through the driver 129. The hammer 125 that has been driven is brought into contact with the stopper 126 and stopped and held at the bottom dead center.

  The hand grip 107 includes a trigger 141 that energizes and drives the drive motor 113 when a worker who holds the hand grip 107 performs a pull operation, and a rotary safety lever 143 that prohibits the pull operation of the trigger 141. And are arranged. When the safety lever 143 is placed at the locked position indicated by the solid line in FIG. 1, the trigger 141 cannot be pulled, and the safety lever 143 is at the unlocked position indicated by the two-dot chain line (virtual line) in FIG. 1. Pull operation is possible when placed. The trigger 141 corresponds to a “trigger” in the present invention, and a drive motor 113 that is driven by a pulling operation of the trigger 141 and applies a driving force to a pin that is a driving material is a “driving device” in the present invention. Equivalent to. The safety lever 143 corresponds to the “operation member” in the present invention. Further, the lock position relating to the setting of the safety lever 143 corresponds to the “first position where the trigger pulling operation is disabled” in the present invention, and the lock release position is the “trigger pulling operation in the present invention”. This corresponds to the “second position where“

  Further, in each part of the main body 101, a light 145 for irradiating a pin driving area is provided in a connecting area where the motor housing 103 and the hand grip 107 are connected. This connection region is also defined as an extension portion of the hand grip 107 toward the battery case 109 or an extension portion of the motor housing 103 toward the battery case 109. The light 145 of the present embodiment is configured to operate in conjunction with the setting of the safety lever 143. Specifically, when the safety lever 143 is set to the unlocked position, the safety lever 143 is turned on when the light lighting switch 147 is turned on, and the safety lever 143 is set to the locked position. Sometimes, the light turn-on switch 147 is turned off to turn off the light. The light 145 constitutes an “illumination device” in the present invention, and the light lighting switch 147 corresponds to the “illumination switch” in the present invention. In the present invention, the safety lever and the light lighting switch may be separate components as in this embodiment, or the safety lever itself may be used as the light lighting switch. A more detailed configuration regarding the trigger 141, the safety lever 143, and the light 145 will be described later with reference to FIGS.

  The drive motor 113 includes a first motor drive switch 148 that is directly operated by a trigger 141 and a second motor drive switch that is operated by a switch mechanism 161 that is interlocked with a pulling operation of the trigger 141 (not shown). ) Are energized when each of them is turned on, and the current is cut off when either the first switch 148 or the second switch is turned off. 1 and 3, the first switch 148 and the second switch are arranged so as to overlap each other. For this reason, illustration of the second switch is omitted. When the drive motor 113 is energized, the hammer drive mechanism 119 is driven via the speed reduction mechanism 115 as described above. The hammer drive mechanism 119 moves the hammer 125 up from the bottom dead center while compressing the compression coil spring 127. Push up to the dead center. The hammer 125 that has reached the top dead center is driven downward by the resilient force of the compression coil spring 127, thus completing a single driving operation by the hammer 125.

  In addition, as described above, when the first driving operation by the hammer 125 is performed by pulling the trigger 141, the second switch operated by the switch mechanism 161 has completed the first pin driving operation. Even if the pulling operation of the trigger 141 is maintained as it is at the time, it is configured to be turned off. That is, when the first pin driving operation by the hammer 125 is completed, the drive motor 113 is de-energized at that time, and even if the pulling operation of the trigger 141 is maintained, the configuration cannot be shifted to the second pin driving operation. Has been. This prevents so-called double hitting of the pin, but since this double hit prevention is not directly related to the present invention, the detailed description of the configuration is omitted. In addition, when the pulling operation of the trigger 141 is canceled after the drive motor 113 is energized by the pulling operation of the trigger 141 and before the pin driving operation by the hammer 125 is completed, the first operation is performed directly by the trigger 141. 1 switch 148 is turned off, and it is possible to interrupt the driving operation of the pin by the hammer 125 by cutting off the energization to the drive motor 113.

  Here, the further detailed structure regarding the trigger 141, the safety lever 143, and the light 145 will be described with reference to FIGS. 4 is a partially enlarged view of the pin tacker 100 in FIG. 1, and FIG. 5 is a view schematically showing the pin tacker 100 in FIG.

  As shown in FIG. 4, the safety lever 143 is provided with an elastic spring 144 that elastically biases the safety lever 143 from the unlocked position indicated by the two-dot chain line in FIG. 4 to the locked position indicated by the solid line. Yes. This elastic spring 144 corresponds to the “biasing means” in the present invention. Accordingly, when the operator rotates the safety lever 143 in the direction of the arrow 10 in FIG. 4 with a force stronger than the elastic biasing force of the elastic spring 144, the safety lever 143 is elastically applied to the elastic spring 144. It is configured to rotate from the locked position to the unlocked position by overcoming the force. On the other hand, when the operator releases the safety lever 143 or the force pulling the safety lever 143 is weaker than the elastic biasing force of the elastic spring 144, the safety lever 143 is unlocked according to the elastic biasing force of the elastic spring 144. It is configured to automatically return from the position to the locked position. At this time, the safety lever 143 is rotated by the operator's middle finger or ring finger, and the trigger 141 is pulled by the operator's index finger or middle finger.

  In the pulling operation of the safety lever 143, when the safety lever 143 rotates about the rotation shaft 143b in the direction of the arrow 10 in FIG. The pressing member 146 is pressed. The pressed member 146 rotates from the position indicated by the solid line in FIG. 4 to the position indicated by the two-dot chain line (virtual line) around the rotation shaft 146a by the pressing force from the safety lever 143. Sometimes, the switch contact 147a which is elastically deformable of the light lighting switch 147 is pressed in the ON direction against the elastic force. Thus, when the safety lever 143 is operated in the unlocking direction, the trigger 141 can be pulled, the light lighting switch 147 is turned on, and the light 145 is turned on (irradiation state). . When the light 145 is turned on, an irradiation region 145 a is formed at the tip portion of the emission unit 112. The irradiation region 145a is configured as a region including a driving region in which a pin is driven into the workpiece W (corresponding to “a workpiece” in the present invention).

  On the other hand, in releasing the pulling operation of the safety lever 143, when the safety lever 143 rotates in the lock position direction around the rotation shaft 143b, the pressed member 146 by the pressing portion 143a on the distal end side of the safety lever 143 is released. Pressing is released. When the pressing force from the safety lever 143 is released, the pressed member 146 returns to the position indicated by the solid line in FIG. 4 around the rotation shaft 146a. At this time, the light lighting switch 147 The switch contact 147a is elastically returned to the off direction when the pressing force from the pressed member 146 is released. Thus, when the safety lever 143 is operated in the locking direction, the pulling operation of the trigger 141 becomes impossible, the light lighting switch 147 is turned off, and the light 145 is turned off.

In such a configuration, when a pin driving operation is performed, the operator rotates the safety lever 143 with the middle finger or the ring finger. In conjunction with this pulling operation of the safety lever 143, the light lighting switch 147 is turned on and the light 145 is turned on. In the state where the light 145 is turned on, the position of the injection portion 112 can be adjusted to a desired part of the workpiece W by bringing the injection portion 112 close to or in contact with the workpiece W. The operator further pulls the trigger 141 with the index finger or the middle finger while the safety lever 143 is still rotated with the middle finger or the ring finger. As a result, a pin driving operation is performed in a state where the light 145 is irradiated toward the driving region.
On the other hand, when the pin driving operation is finished, the pulling operation of the trigger 141 and the safety lever 143 is released. The pin driving operation is stopped by releasing the pulling operation of the trigger 141, and the light lighting switch 147 is turned off in conjunction with the release of the pulling operation of the safety lever 143 so that the light 145 is turned off.

  According to such a configuration related to the safety lever 143, the operation of turning on the light 145 is performed in conjunction with the pulling operation for setting the safety lever 143 in the unlocking direction. There is no need to do it. Therefore, it is possible to construct a pin tacker that is easy to use and has high operability. At this time, the pulling operation of the safety lever 143 is performed prior to the pulling operation of the trigger 141, and the actual pin driving operation is performed after the light 145 is turned on. This is effective for surely aligning the position of the injection portion 112 with a desired portion of W.

  In addition, when the operator has an intention of driving operation and the safety lever 143 is pulled, the light 145 is turned on in conjunction with the pulling operation, while the operator has no intention of driving operation. When the pulling operation of the safety lever 143 is released, the light 145 is turned off in conjunction with the release of the pulling operation. Therefore, it is reasonable to reduce the battery power consumption related to the light 145.

  Further, as shown in FIG. 5, the light 145 in the pin tacker 100 of the present embodiment is a predetermined position on the left side of the main body 101, specifically, a predetermined distance to the grip tip side of each part of the handgrip 107. It is arranged at a position separated by only. Therefore, the direction of irradiating the driving area of the light 145 (direction to the irradiation area 145a) is from the left side in FIG. 5 to the driving area. When the right-handed operator operates the pin tacker 100, the line of sight of the worker is directed from the left side in FIG. 5 to the driving area. At this time, in the connection region between the motor housing 103 and the hand grip 107, the pin tacker 100 in a state where the hand grip 107 is gripped by a right-handed operator is set by appropriately adjusting the setting position of the light 145. When viewed from the arrow B direction (worker side) in FIG. 1, the direction of the line of sight toward the worker's driving area and the direction of irradiating the driving area of the light 145 (direction to the irradiation area 145a) Are substantially overlapped.

  In addition, when targeting a left-handed worker, it can be configured to be disposed at a predetermined position on the right side of the main body 101 (a position symmetrical to the position of the light 145 in FIG. 5). Also, a pair of left and right lights 145 in FIG. 5 are provided at positions that are symmetrical with respect to each other, and a light that is turned on is switched by a switch or the like when a right-handed worker works or when a left-handed worker works. It can also be configured to select as appropriate.

  According to such a configuration relating to the arrangement of the light 145, when the operator looks at the driving area at the time of driving the pin, the irradiation light from the light 145 is not obstructed (obstructed) by the gear housing 105 or the like. The light 145 is irradiated from the direction in which the operator can easily see, and the shadow around the emission unit 112 is hardly formed in the driving area. Therefore, the operator can easily recognize the driving area, which is effective for facilitating the driving operation.

  In addition, as a work form of the pin tacker 100, not only low place work but also high place work is assumed. In such a high-altitude work, there is a case where the operator performs a pin driving work while looking up at the pin tacker 100 from below. In such a case, if the configuration in which the direction of the line of sight toward the worker's driving area and the direction of irradiating the driving area of the light 145 are substantially overlapped as in the present embodiment, the operator is further increased. Therefore, it is possible to further facilitate the driving operation.
