FIG. 13 is a partially enlarged perspective view of a nose portion according to a second modification.

  An embodiment of the present invention will be described with reference to the drawings.

  The driving tool 10 according to the present embodiment can be used for, for example, tongue joint work of a floor material, and as shown in FIG. 1, a tool body 11 having a hitting mechanism inside, and a rear side of the tool body 11. , A trigger 14 operably provided on the grip 12, a magazine 13 connected near the tip of the tool body 11, and a nose portion provided to protrude from the tip of the tool body 11. 20.

  The striking mechanism built into the tool body 11 is operated by a known method, and operates the driver 15 using a force such as compressed air, explosion of gaseous fuel, or a spring restoring force. As shown in FIG. 2, the driver 15 is movable in the direction of the nose portion 20 in order to strike the nail, and moves in the nail driving direction when the impact mechanism generates a shocking force, The nail set in the nose part 20 is driven out.

  When using the driving tool 10, the grip 12 is gripped and gripped, and the trigger 14 is pulled. With this operation, the above-described hitting mechanism is operated, and the nail is driven.

  In the magazine 13, a connecting nail formed by connecting U-shaped staple nails is accommodated. The connecting nail is pressed forward by the pusher 16, and the leading nail is sequentially supplied in the direction of the nose portion 20 (just below the driver 15 before the driving operation).

  The nose portion 20 protrudes so as to be able to be pressed against the material 30 to be driven, and in this embodiment, also functions as a part of a safety device. That is, the nose portion 20 is provided so as to be able to reciprocate in the nail driving direction, and its tip protrudes from the tool body 11. When the nose portion 20 is pressed against the material 30 to be driven, the nose portion 20 moves upward relative to the tool body 11. When the nose portion 20 moves upward as described above, a switch (not shown) or the like is pressed to release the safety device, and the nail can be driven. In other words, the configuration is such that the trigger 14 cannot be operated or the nail is not driven out even if the trigger 14 is operated until the nose portion 20 is pressed against the driven material 30 and moves upward.

  At the tip of the nose portion 20, as shown in FIG. 3 and the like, an injection port 20a is formed so that a nail can be injected from the injection port 20a. The injection port 20a is formed to be horizontally long since one staple nail is injected one by one. The front and rear surfaces of the nose portion 20 include a parallel surface 20b parallel to the nail driving direction, and an inclined surface 20c provided on the tip side of the parallel surface 20b. The front and rear inclined surfaces 20c are each inclined at an angle of about 45 degrees with respect to the nail driving direction, and the front inclined surface 20c and the rear inclined surface 20c intersect at a substantially right angle at the tip of the nose portion 20. ing.

  The nose portion 20 is configured such that a front member 21 that supports the front side of the driver 15 and a rear member 22 that supports the rear side of the driver 15 are connected back and forth by bolts 23. When the front member 21 and the rear member 22 are fitted back and forth, a nail injection path is formed between the front member 21 and the rear member 22. The injection path is open at the tip to form an injection port 20a. When the striking mechanism operates, the driver 15 reciprocates in the injection path, and the nail is driven.

  As shown in FIGS. 3 and 4, the front member 21 includes a pair of bolt mounting portions 21 a provided for mounting the bolts 23, a parallel surface portion 21 b continuous with the distal end side of the bolt mounting portion 21 a, and a parallel surface portion 21 b And an inclined surface portion 21c that is continuous with the tip side of The parallel surface portion 21b is a portion forming the parallel surface 20b of the nose portion 20, and the front surface and the rear surface are formed parallel to the nail injection direction. The inclined surface portion 21c is a portion that forms the inclined surface 20c of the nose portion 20, and the front surface and the rear surface are inclined with respect to the nail injection direction. Grooves 21d are formed vertically in the center of the rear surface of the front member 21. The groove 21d is covered with the rear member 22 to form a nail injection path.

  The rear member 22 includes a pair of bolt mounting portions 22a provided for mounting the bolts 23, a parallel surface portion 22b continuous to the distal end side of the bolt mounting portion 22a, and an inclined surface portion 22c continuous to the distal end side of the parallel surface portion 22b. And. The parallel surface portion 22b is a portion that forms the parallel surface 20b of the nose portion 20, and the front surface and the rear surface are formed parallel to the nail injection direction. The inclined surface portion 22c is a portion that forms the inclined surface 20c of the nose portion 20, and the front surface is inclined with respect to the nail injection direction. In the present embodiment, the parallel surface portion 22b has a tapered shape when viewed from behind, and the inclined surface portion 22c also has a tapered shape when viewed from behind.

  By the way, as shown in FIG. 3B, the tip width W2 of the rear member 22 is formed smaller than the tip width W1 of the front member 21. The rear member 22 has a color different from that of the front member 21. More specifically, the front member 21 has been subjected to a surface treatment by plating to have a metallic color, and the rear member 22 has been subjected to a surface treatment by black dyeing to be black. With this configuration, as shown in FIG. 5, it is easy to grasp the position of the injection port 20a even when a nail is driven into the tongue 31 of the material 30 to be driven.

  That is, when the floor material is nailed to the base material, the tip of the nose portion 20 is hit against the corner 32 of the tongue 31 of the material 30 to be nailed. At this time, the operator checks the nail driving position while viewing the nose portion 20 from behind. The tip width W2 of the rear member 22 of the present embodiment is smaller than the tip width W1 of the front member 21 (that is, the tip width of the nose portion 20), and the injection port 20a is provided on an extension of the rear member 22. Therefore, the operator can predict the position of the injection port 20a by looking at the rear member 22 and work. In particular, in the present embodiment, since the tip end width W2 of the rear member 22 is equal to the width of the injection port 20a, it is possible to accurately predict the driving position and work. The rear member 22 has a color different from that of the front member 21 so that it can be easily visually recognized, and the position of the injection port 20a can be easily identified even in a dark place or the like.

  As described above, according to the present embodiment, the nose portion 20 includes the front member 21 that supports the front side of the driver 15 and the rear member 22 that supports the rear side of the driver 15. The tip width W2 of the front member 21 is smaller than the tip width W1 of the front member 21, and the rear member 22 has a different color from the front member 21. According to such a configuration, by increasing the tip width W1 of the front member 21, the tip width of the nose portion 20 is increased, and the posture at the time of driving can be stabilized. Further, since the rear member 22 has a small tip width and a different color, the position of the injection port 20a can be determined using the rear member 22 as a mark. Therefore, it is possible to achieve both stabilization of the posture at the time of driving and confirmation of the injection position. In addition, since the indication of the injection position can be realized without forming irregularities on the surface, the irregularities do not damage the surface of the floor material or the like.

  In order to make the rear member 22 and the front member 21 have different colors, at least one of the rear member 22 and the front member 21 is subjected to a surface treatment by plating or painting. According to such a configuration, unlike a seal, for example, it does not easily peel off, so that it is possible to enhance the durability of the mark display of the injection position.

  In addition, since a color difference is realized by combining a plurality of members (the front member 21 and the rear member 22), in order to indicate the injection position, one of the members is partially colored or painted. There is no need to paint separately. In particular, it is difficult to partially change the color of plating and black dyeing, but it is only necessary to perform different surface treatments on the front member 21 and the rear member 22. Can be suppressed.

  In addition, the rear member 22 has a tapered shape whose width decreases toward the injection port 20a. According to such a configuration, the width of the rear member 22 is narrowed toward the injection position, so that the nail driving position can be more easily aimed.

  Further, the tip end width W2 of the rear member 22 is equal to the width of the injection port 20a. According to such a configuration, the position of the injection port 20a can be known more accurately.

  Note that the shape of the rear member 22 is not limited to the shape of the above-described embodiment, and can be appropriately changed according to the nail used by the driving tool 10 or the like. For example, as shown in FIGS. 6 and 7, only the parallel surface portion 22b may be tapered when viewed from the rear, and the inclined surface portion 22c may not be tapered. Even with such a shape, since the rear member 22 is formed in a tapered shape as a whole, the width of the rear member 22 is narrowed down toward the injection position, so that the nail driving position can be easily aimed. be able to.

  Further, in the above-described embodiment, no projection is provided on the parallel surface portion 21b and the inclined surface portion 21c of the front member 21 and the parallel surface portion 22b and the inclined surface portion 22c of the rear member 22, and the surface is flat. . However, as shown in FIG. 8, a protrusion 22 d may be provided on the rear surface of the parallel plane portion 22 b of the rear member 22, and the color of the protrusion 22 d may be different from that of other portions of the rear member 22. According to such a configuration, the position of the injection port 20a can be made prominent by using the projection 22d.

More specifically, the front member 21 has been subjected to a surface treatment by plating to have a metallic color, and the rear member 22 has been subjected to a surface treatment by black dyeing to be black. With this configuration, as shown in FIG. 5, it is easy to grasp the position of the injection port 20a even when a nail is driven into the tongue 31 of the material 30 to be driven.

  That is, when the floor material is nailed to the base material, the tip of the nose portion 20 is hit against the corner 32 of the tongue 31 of the material 30 to be nailed. At this time, the operator checks the nail driving position while viewing the nose portion 20 from behind.

The tip width W2 of the front member 21 is smaller than the tip width W1 of the front member 21, and the rear member 22 has a different color from the front member 21. According to such a configuration, by increasing the tip width W1 of the front member 21, the tip width of the nose portion 20 is increased, and the posture at the time of driving can be stabilized. Further, since the rear member 22 has a small tip width and a different color, the position of the injection port 20a can be determined using the rear member 22 as a mark. Therefore, it is possible to achieve both stabilization of the posture at the time of driving and confirmation of the injection position. In addition, since the indication of the injection position can be realized without forming irregularities on the surface, the irregularities do not damage the surface of the floor material or the like.

  In order to make the rear member 22 and the front member 21 have different colors, at least one of the rear member 22 and the front member 21 is subjected to a surface treatment by plating or painting. According to such a configuration, unlike a seal, for example, it does not easily peel off, so that it is possible to enhance the durability of the mark display of the injection position.

  In addition, since a color difference is realized by combining a plurality of members (the front member 21 and the rear member 22), in order to indicate the injection position, one of the members is partially colored or painted. There is no need to paint separately. In particular, it is difficult to partially change the color of plating and black dyeing, but it is only necessary to perform different surface treatments on the front member 21 and the rear member 22. Can be suppressed.

  In addition, the rear member 22 has a tapered shape whose width decreases toward the injection port 20a. According to such a configuration, the width of the rear member 22 is narrowed toward the injection position, so that the nail driving position can be more easily aimed.

  Further, the tip end width W2 of the rear member 22 is equal to the width of the injection port 20a. According to such a configuration, the position of the injection port 20a can be known more accurately.

  Note that the shape of the rear member 22 is not limited to the shape of the above-described embodiment, and can be appropriately changed according to the nail used by the driving tool 10 or the like. For example, as shown in FIGS. 6 and 7, only the parallel surface portion 22b may be tapered when viewed from the rear, and the inclined surface portion 22c may not be tapered. Even with such a shape, since the rear member 22 is formed in a tapered shape as a whole, the width of the rear member 22 is narrowed down toward the injection position, so that the nail driving position can be easily aimed. be able to.

  Further, in the above-described embodiment, no projection is provided on the parallel surface portion 21b and the inclined surface portion 21c of the front member 21 and the parallel surface portion 22b and the inclined surface portion 22c of the rear member 22, and the surface is flat. . However, as shown in FIG. 8, a protrusion 22 d may be provided on the rear surface of the parallel plane portion 22 b of the rear member 22, and the color of the protrusion 22 d may be different from that of other portions of the rear member 22. According to such a configuration, the position of the injection port 20a can be made prominent by using the projection 22d.
