Description

  The present invention relates to a fastener driving tool having a head meshed at one end of a shaft such as a nailing machine or a hammer driving machine, and is particularly suitable for a gas combustion type driving tool.

  Driving tools such as nailers and nailers use compressed air as a power source and those using gas combustion pressure.

  Regardless of the driving principle, the driving tool includes a main body in which a rod-shaped rod for driving out fasteners such as nails, a head provided on the front surface of the main body for guiding the driving of fasteners by the rod, and a rod And a magazine for supplying fasteners one by one from below.

  Also, in order to prevent the fastener from being fired towards a person or into the air, a safety device is provided to prevent the rod from moving forward even if the trigger is simply pulled. The head is provided with a probe that moves backward when pressed against the workpiece, and the safety device is unlocked by the backward movement of the probe.

  The head includes an inner guide body that guides the forward movement of the fastener and the rod, and there are a head that is configured as a separate member from the inner guide body and a head that is also used as the probe. Further, in the gas combustion type driving tool, if the operator can easily operate the probe by hand, the meaning of the safety device is lost, and therefore, most of the head is covered with a shroud (cover).

  By the way, as a workpiece to be fastened with a gas type driving tool, for example, there is a grooved steel having a small groove width dimension. In the case of such a narrow groove type workpiece, the shroud cannot be held on the end surface of the workpiece and the probe cannot be applied to the construction surface, so that there is a possibility that the fastening operation cannot be performed. In addition, the shroud gets in the way, making it difficult to see the driving location, which makes it difficult to work.

  With regard to this point, it is considered that the tip of the shroud should be made narrow and long, but the shroud is generally manufactured by sheet metal processing and has a large processing error. Can not do it. On the other hand, the problem of driving into a narrow groove can be dealt with by increasing the length of the probe. However, if the probe protrudes greatly from the shroud, a person can easily operate the probe, which makes it meaningless as a safety device. End up. The first object of the present invention is to improve such a current situation.

  By the way, magazines are roughly classified into drum-shaped and elongated linear ones, and linear magazines are generally used for gas-fired driving tools. The linear magazine is loaded with a connecting fastener in which a plurality of fasteners arranged in parallel are connected by a connecting tool, and the connecting fastener is pushed by a follower urged by a spring. It has become.

  The follower is provided with a claw that pushes the end of the connecting fastener, but it is not a stopper that pushes the connecting fastener toward the head to the end with the claw, but a stopper that stops the follower with the last two left. Is provided. This is to prevent interference between the rod and the claw, and the stopper is set so as to hit the upper end of the head or magazine. When the follower moves to the end and stops, the next connected fastener is loaded, and the fasteners remaining in the magazine are pushed by the subsequent connected fasteners, so that all preceding fasteners are driven out.

  In order to keep the safety device from being unlocked even if the probe is pressed against the workpiece while the follower is stopped and, for example, two fasteners remain, the probe is moved backward by a stopper provided on the follower. However, the second object of the present invention is to use a simple structure to hold the last fastener in a locked state in a driving tool of the type in which the inner guide also serves as a probe. It is to be realized.

  The driving tool according to the present invention has, as a basic structure, a main body in which a rod-shaped rod for punching fasteners such as nails and scissors is built in, a head provided on the front surface of the main body, and a fastener one by one in front of the rod And a magazine loaded with a connecting fastener, and the head has a main probe that retreats when it hits the workpiece, and when the main probe is fully retracted, the safety device is unlocked and the rod moves forward. Is set to be possible.

  According to the first aspect of the present invention, the head is provided with a cylindrical auxiliary probe that protects the main probe from being manually operated by a person without damaging the backward movement of the main probe.

  According to a second aspect of the present invention, in the first aspect, the magazine is provided with a follower for moving a connected fastener formed by connecting a group of fasteners arranged in parallel with a connecting tool toward the head by a spring. It is set so that one or more fasteners remain in the magazine or in the head with the follower fully moved to the end.

  The main probe also serves as a guide for a fastener and a rod, and is set so that the auxiliary probe is retracted by being pushed by the main probe, and the follower is completely moved to the end. And a stopper for preventing the auxiliary probe from moving backward.

  In the invention of claim 1, for example, even if the main probe is elongated so that a fastener can be driven into a narrow groove-like portion, the presence of the auxiliary probe allows a person to operate the main probe by hand. The lock cannot be released. For this reason, the function as a safety device can be ensured while being a user-friendly tool that can be driven into a narrow portion.

  When the follower is stopped at the end, the auxiliary probe cannot be moved backward and the main probe cannot be moved backward. Therefore, the last one or more fasteners are attached to the magazine or the head. However, since this lock is performed using an auxiliary probe, the structure can be simplified accordingly.

  Next, embodiments of the present invention will be described with reference to the drawings. In the following description, when displaying directions such as front / rear / left / right / up / down, the terms front / rear / left / right / up / down are used with reference to an operator who performs a driving operation on a wall.

(1) Overall Overview This embodiment is applied to a tool that uses gas combustion pressure as a rod drive mechanism. 1 to 16 show a first embodiment, in which FIG. 1 is an overall side view, FIG. 2 is a side view in a separated state, FIG. 3 is a longitudinal side view, and FIG. FIG.

  As shown in FIGS. 1 and 2, the driving tool includes a main body 1 incorporating a driving rod (blade) 2, a head 3 provided at the front end of the main body 1, and a magazine 4 overlapping the head 3 and the main body 1. It has. The head 3 has a protective shroud 5.

  The main body 1 includes a hollow housing 6, and the main body 1 also includes a grip 7 that is inclined in a side view, and the grip 7 is provided with a trigger 8. Although details are omitted, a gas cylinder (gas cartridge) serving as a driving source is loaded in a hollow portion above the grip 7 in the main body.

  The magazine 4 includes a storage portion 10 having a vertically long guide 9 and a mounting portion 11 that overlaps the front surface of the main body 1. The front surface of the main body 1 is inclined in a side view, and therefore the back surface of the mounting portion 11 is also inclined in a side view.

  A connecting fastener 14 formed by connecting a plurality of fasteners 12 arranged in parallel with a connecting tool 13 into the guide groove 9 of the storage unit 10 is loaded from below. On the up-block 15 provided at the upper end of the storage portion 10, two right and left pins 16 for positioning extend in an inclined manner.

  Further, the storage unit 10 is equipped with a follower (pusher) 17 for pushing the connecting fastener 14 upward. The follower 17 is pulled upward (in the direction of the head 3) by a spring (not shown). The lower end portion of the attachment portion 11 and the lower end portion of the grip 7 are fastened with a screw provided with a knob 9a.

  As shown in FIG. 3, a cylinder 18 is disposed inside the housing 6, and a piston (not shown) including the rod 2 is slidably fitted into the cylinder 18. A cushion rubber 23 is fitted into the front end of the cylinder 18.

  Although not shown, a combustion chamber is formed at the rear of the cylinder 18, and when the safety sleeve fitted to the cylinder 18 slidably from the outside moves backward, the combustion chamber is closed and the combustion chamber is filled with fuel gas. When the trigger 8 is pulled, the gas is ignited by the discharge of the plug, and the piston and the rod 2 move forward. The burned gas is discharged to the outside through an exhaust hole provided in the housing 6.

  The driving tool is provided with a safety device that locks the rod 2 so that the rod 2 does not advance only by pulling the trigger 8. For example, a part of the safety device may be a valve device provided in an appropriate portion of a pipe or the like for supplying fuel gas to the cylinder 18. In this case, unless the lock to the valve device is released, the fuel gas cannot be supplied to the combustion chamber even if the trigger 8 is pulled.

  A recess 19 opening forward is formed at the front end of the cylinder 18, and the front end of the first intermediate probe 20 is fitted into the recess 19. The first intermediate probe 20 is biased forward by a spring 21. As shown in FIG. 4, the first intermediate probe 20 is provided with a four-pronged foot 20a. When the foot 20a is retracted, the safety sleeve is retracted and the safety device is unlocked. The Note that the foot 20 a of the first intermediate probe 20 does not interfere with the cylinder 18 and the housing 6.

  A front plate 22 that closes the recess 19 is attached to the front end of the cylinder 18. Although not shown, an exhaust hole is formed in the front portion of the peripheral wall of the cylinder 18, and air and combustion gas pushed by the forward movement of the piston are discharged from the exhaust hole to the outside of the cylinder 18. . The housing 6 has a forward opening for allowing exhaust to escape.

(2). Structure of Head Next, the structure of the head 3 will be described with reference to FIGS. 5 to 10 in addition to FIGS. 5 is a plan view with the shroud 5 broken, FIG. 6 is a longitudinal side view of the main part, FIG. 7 is a sectional side view of the main member, and FIG. 8A is a view taken along line AA in FIG. Sectional view, (B) is a sectional view taken along line BB in FIG. 3, (C) is a sectional view taken along line CC in FIG. 3, and (A) of FIG. 9 is a sectional view taken along line AA in FIG. (B) is a cross-sectional view taken along the line BB of FIG. 5, and FIG. 10 is a cross-sectional view showing a driving state.

  The head 3 serves as a guide for the fastener and the rod 2, and forms a substantially cylindrical main probe 24 that forms a part of the safety device, a main guide body 25 that controls the guide of the main probe 24, and a front portion of the main probe 24. A fitted auxiliary probe 26, a second intermediate probe 27 that moves back in conjunction with the backward movement of the main probe 24, and the shroud 5 as protective means are provided. The shroud 5 is fixed to the front surface of the main body 1 with a special screw 28.

  For example, as can be easily understood from FIG. 4, the main guide body 25 has a distal end portion formed in a small diameter cylindrical portion 25a and a substantially rear half portion formed in a wide width portion 25b. By providing 25c, the slit 30 of the up-and-down opening is formed in the longitudinal direction where the block body 29 fits slidably.

  The wide portion 25 b is provided with an attachment hole 31 for attaching the main guide 25 to the main body 1 and a positioning hole 32 for positioning the magazine 4. The main guide 25 is attached to a receiving portion (not shown) protruding from the front surface of the main body 1 with pins or screws. The main guide 25 can be integrally formed with the main body 1 (that is, non-detachable).

  As can be understood from FIG. 3, the main guide body 25 opens downward except for the small-diameter cylindrical portion 25a and the rear end portion. Needless to say, this is to allow passage of the fastener 12. The block body 29 is fixed to the second intermediate probe 27 with a screw 37, the rear end of the second intermediate probe 27 is bent downward, and the downward bent portion 27a of the first intermediate probe 20 is inserted through a washer. It is in contact with the front end. The second intermediate probe 27 is urged in the forward direction by the spring 21. Therefore, the tip of the block body 29 is in contact with the front surface of the slit 30 in a non-driving state.

  The main probe 24 is made of metal, and a slight length (for example, about 10 mm) of the tip portion thereof becomes a large diameter portion 24a, and the rear portion thereof is divided into an intermediate diameter portion 24b and a small diameter portion 24c having the same length. It is configured. Therefore, the main probe 24 includes the first step portion 33 and the second step portion 34, and the front end of the block body 29 is in contact with the second step portion 34. For this reason, when the main probe 24 moves backward, the block body 29 and the second intermediate probe 27 are also pushed and moved backward.

  The main probe 24 has an intermediate diameter portion 24b fitted into the small diameter cylindrical portion 25a of the main guide body 25 and a rear end portion of the small diameter portion 24c fitted into the rear end cylindrical portion 25d of the main guide body 25, so that only the forward and backward movement is performed. Held possible. The main probe 24 is formed with a slot 35 having a downward opening for allowing the fastener 12 to enter (see FIGS. 4 and 8).

  The front end of the shroud 5 is located at the same level as the front end of the magazine 4, so that the main probe 24 extends greatly forward from the front end of the magazine 4. On the other hand, the auxiliary probe 26 is slidably fitted into a portion of the main probe 24 that protrudes from the shroud 5 from the outside, and therefore most of the auxiliary probe 26 is exposed from the shroud 5.

  For example, as shown in FIGS. 6 and 8, the auxiliary probe 26 has an inner diameter that is slidably fitted into the large-diameter portion 24a of the main probe 24, and the inner surface of the main probe 24 on the inner surface near the front end thereof. An inward projection 36 that can contact the first step portion 33 is provided. For this reason, when the main probe 24 retreats to some extent L1, the auxiliary probe is pushed by the first step 33 and retracts together with the main probe 24. The dimension L1 in which only the main probe 24 is retracted is set to a dimension smaller than the retracting stroke L necessary for unlocking the safety device.

  In the present embodiment, a plurality (three) of inward projections 36 of the auxiliary probe 26 are provided along the circumferential direction. This is in order to eliminate the twist and make the relative movement smoothly.

  The outer diameter of the small-diameter cylindrical portion 25a of the main guide body 25 is set to be almost the same as the large-diameter portion 24a of the main probe 24, and the auxiliary probe 26 is also slidable from the outside to the small-diameter cylindrical portion 24a of the main probe 24. It is fitted.

  The auxiliary probe 26 is provided with a rearward plate portion 26a that enters the slit 30 of the main guide body 25, and a longitudinally long slot 38 is formed in the rearward plate portion 26a, while the left and right wall portions of the main guide body 25 are formed. A stay 39 is fixed to the upper surface of 25c with a screw 40, and a shaft portion of a guide screw 41 fixed to the left and right intermediate portion of the stay 39 by welding or screwing or the like is fitted into the elongated hole 38. For this reason, the auxiliary probe 26 is held non-rotatable. The guide means may use pins instead of the screws 41.

  Further, the rear end of the backward-facing plate portion 26a of the auxiliary probe 26 is close to the block body 29, and therefore, only the auxiliary probe 26 can hardly be retracted. A long groove 42 is formed in the main probe 24 to prevent interference with the guide screw 41.

  The auxiliary probe 26 is provided with a side stopper 26b that extends rearward toward the outside of the upper side surface of the magazine 4 (the relationship with the magazine will be described later). It is also possible to provide spring means for urging the auxiliary probe 26 in the backward direction.

  As shown in FIG. 10, when the tip of the main probe 24 is pressed against the workpiece W, the main probe 24 is retracted, but the auxiliary probe 26 is also pressed during the retraction, and is retracted together. The safety device is unlocked in the state. For this reason, when the trigger 8 is pulled, the rod 2 moves forward and the fastener 12 is driven into the workpiece W.

  Since the main probe 24 and the auxiliary probe 26 protrude greatly from the front end of the shroud 5, even if the workpiece W is a narrow groove steel, the driving operation can be reliably performed. Further, since most of the main probe 24 is hidden by the auxiliary probe 26 and an operator cannot pick up the main probe 24 with a finger and retract it, the safety function is not hindered.

  The auxiliary probe 26 can be machined as a casting, or can be machined out using a metal round bar or pipe material as a raw material. For this reason, the outer diameter can be secured while ensuring sufficient strength and dimensional accuracy. Can be made as small as possible. Accordingly, the outer diameter is much smaller than when the front portion of the shroud 5 is elongated in a cylindrical shape.

  The second intermediate probe 27 and its set screw 37 are completely surrounded by the shroud 5 and cannot access the screw 37 or the second intermediate probe 27 from the outside. Further, since the second intermediate probe 27 is surrounded by the left and right wall portions 25c of the main guide body 25, even if the magazine 4 is removed, the second intermediate probe 27 and the screw can be moved with a tool such as a screwdriver. Can not. The front end of the shroud 5 is slightly cylindrical, but this is for ensuring strength.

(3). Magazine Structure Next, the magazine 4 will be described with reference to FIGS. 11 is a perspective view with only the magazine removed, FIG. 12 is a side view with the head 3 attached, FIG. 13 is a sectional view taken along line XIII-XIII in FIG. 12, and FIG. 14 is a view taken along line XIV-XIV in FIG. 15 is a cross-sectional view taken along the line XV-XV in FIG. 16A, FIG. 16A is a side view of the follower 17 moved at the end (upper end), and FIG. FIG.

  As described above, the magazine 4 includes the storage unit 10 and the attachment unit 11, but only the storage unit 10 is shown in FIG. 11. The attachment portion 11 is composed of a split case 43 (see also FIGS. 1 and 2), and the case 43 is fixed to the storage portion 10. The storage portion 10 is composed of a plurality of members, and the guide groove 9 into which the connecting fastener 14 is loaded is formed therein.

  The up-block 15 fixed to the upper end of the storage unit 10 has a long hole 44 through which the fastener 12 passes. As described above, the magazine 4 includes the split case 43, and the upper ends of both cases 43 are fixed to the up block 15 with the screws 45. For this reason, the screw hole 46 is vacant in the up-block 15.

  As shown in FIG. 14, the follower 17 is provided with a claw 47 that presses the end of the coupling fastener 14. When the follower 17 is retracted to the start end (lower end), the claw 47 rotates so as to be detached from the guide groove 9, and the connecting fastener 14 can be loaded into the guide groove 9 from below the storage portion 10.

  When the claw 47 of the follower 17 enters the inside of the main probe 24, the rod 2 interferes with the claw 47, and the fastener 12 may fall so that the tip is directed upward. For this reason, the follower 17 is provided with a stopper 48 that abuts the lower surface of the main guide body 25 and regulates the end position.

  In the present embodiment, as shown in FIG. 15, the two fasteners 12 are set to remain in the magazine 4 in a state where the stopper 48 is in contact with the main guide body 25. When the follower 17 moves to the end, the follower 17 is retracted and a new connecting fastener 14 is loaded. The remaining two fasteners 12 are pushed by a new connecting fastener 14 and driven out.

  The stopper 48 of the follower 17 is disposed so as to overlap the side surface of the housing portion 10 near the front surface. Further, the up block 15 is provided with a notch 49 for preventing interference with the stopper 48, and the notch 49 is provided with a forward projection 50 for preventing the stopper 48 from falling down. .

  In the state where the follower 17 has completely moved to the end, the backward movement of the side stopper 26b of the auxiliary probe 26 is set to be blocked by the stopper 48. As can be understood from FIG. 8C, the side stopper 26b of the auxiliary probe 26 is set so as to enter the notch 49 of the up-block 15 when retracted. For this reason, the side stopper 26b does not move in the normal driving state. There is no interference with the up-block 15.

  As can be understood from the above description, in the state where the follower 17 has moved all the way to the end, the auxiliary probe 26 can hardly move backward, so even if the operator accidentally presses the main probe 24 against the workpiece W, The main probe 24 cannot be retracted to the unlocked position. That is, the locked state is maintained. For this reason, the last fastener 12 remaining in the magazine 4 is not driven out in an unstable posture.

  By the way, in the type in which the inner guide body that guides the fastener 12 and the rod 2 is also used as the main probe 24, conventionally, as a means for holding the follower 17 in a state where it has been moved to the end, the follower is conventionally used. The stopper provided in 17 (the arrangement position is different from the present embodiment) is applied to a member corresponding to the second intermediate probe 27.

  On the other hand, the driving tool of the type in which the inner guide is fixed and the main probe is fitted at the tip of the inner guide uses the same follower 17 as in the present embodiment, and the locked state is achieved by applying the stopper 48 to the main probe. Was holding. Therefore, conventionally, two types of followers have been used for each type of driving tool.

  On the other hand, in the present invention, since the same type of follower can be used for the driving tool for the fixed inner guide and the driving tool for the movable inner guide, the members can be made common to contribute to cost reduction. Further, in the type in which the inner guide is formed of the main probe, it is not necessary to apply a stopper to the second intermediate probe as in the prior art, so that the structure can be simplified in this respect as well.

(4). Other Embodiments FIG. 17 shows an outline of another embodiment. Of these, in the second embodiment shown in (A), the auxiliary probe 26 is fixed so that only the main probe 24 slides. The auxiliary probe 26 is configured separately from the main guide body, and such a fixed auxiliary probe and structure are included in the present invention.

  In the third embodiment shown in (B), the auxiliary probe 26 is set to slide by the same dimension as the main probe 24. However, even if the auxiliary probe 26 is moved backward, the main probe 24 does not move backward, and the auxiliary probe 26 is moved backward only by the backward movement of the main probe 24.

  In the fourth embodiment shown in (C), the main probe 52 having only the function of the safety device is fitted into the small diameter cylindrical portion 51a of the fixed inner guide 51, and the auxiliary probe 26 can be slid from the outside to the main probe 52. It is fitted in. In the case of this example, as in the first embodiment, the auxiliary probe 26 cannot be independently retracted, but is set to be pushed back by the main probe 52.

  Each of the above embodiments is a case where the head is provided with a shroud, but the present invention can also be applied to a driving tool not provided with a shroud. The example is shown by (D) as 5th Embodiment. That is, in this embodiment, the main probe 24 that also serves as a guide for the fastener 12 and the rod 2 is slidably fitted into the block-shaped main guide body 25, and a portion of the main probe 24 that protrudes from the main guide body 25 is inserted. The majority is covered with the auxiliary probe 26. When the main probe 24 moves backward, the auxiliary probe 26 is also pushed back.

  In this embodiment, the main probe 24 is not exposed to the outside of the main guide body 25, and the safety device is unlocked by pushing an intermediate probe (not shown) at the rear end of the main probe 24. Done. The intermediate probe is covered with the main guide body 25 or disposed inside the main body.

(5). Others The present invention can be embodied in various ways other than the above embodiment. For example, the shape of the main probe or auxiliary probe can be changed as needed. Further, the auxiliary probe can be applied not only to a gas combustion type driving tool but also to other value insertion tools such as a pneumatic driving tool and an explosive driving tool. The magazine may be fixed to the head or the main body. Further, the connecting fastener may be coiled (in this case, the magazine is drum-shaped).

  Furthermore, in the first embodiment, the stopper that regulates the end position of the follower is also used as the stopper for preventing the backward movement of the auxiliary probe. However, it is also possible to configure both of them separately (however, if both are used together, the structure is simple) There is an advantage to become).

  Although it deviates from the present invention, as a safety mechanism that makes it impossible to drive in the state where the follower has moved all the way to the end, the backward movement of the main probe may be directly retracted by a stopper provided on the follower (therefore, In this case, an auxiliary probe is not necessarily required). Furthermore, it is also possible to directly stop the main probe that does not have the fastener and rod guide function with the follower stopper.
