Definitions
- the present invention relates to a contact mechanism attached to a driving tool such as a nailing machine and a screw driving machine for safety.
- a driving tool is a tool for driving a fastener such as a nail screw into wood or concrete, and a contact mechanism is usually provided to ensure safety.
- the contact mechanism is used to validate the trigger valve activation operation that activates the driving tool only when a contact member that is relatively movable along the nose part with the nail injection path is pressed against the workpiece. It is.
- the contact member is normally panel-biased so as to protrude in the driving direction from the tip of the nose part, and when the fastener is driven, the contact member is in contact until the tip of the nose hits the driving part of the workpiece.
- the tip is pressed against the material to be driven, it moves relatively to the opposite side of the pressing direction, and the trigger operation is enabled by detecting that the tip of the nose has hit the material to be driven by this movement. Can do.
- the contact member is strongly pressed by a force greater than the panel load. Therefore, when a fastener is driven into a decorative material, such as when a pin nail is driven into a groove of a skirting board, the tip of the nose portion is narrowed to engage with the groove.
- the surface of the material to be driven may have indentations and other scratches, and if the finish is poor, you may need to start over. For this reason, as a safety work before driving, the contact member must be pressed with a force slightly larger than the panel force, and the operator is required to be careful in adjusting the pressure. Was annoying.
- Japanese Patent Laid-Open No. 2002-283253 always holds the contact member on the top dead center side, that is, keeps the tip of the outer member of the contact and the tip of the nose at the same position, and pulls the trigger. Same as When the contact member sometimes protrudes downward, the trigger operation is enabled when the contact member cannot hit the driven material and cannot be protruded. When the contact member protrudes without hitting anything, the trigger operation is disabled.
- a mechanism is disclosed. According to this mechanism, it is not necessary to perform a safe operation different from the operation of the trigger by pressing the tip of the nose portion against the workpiece, so that the operation can be performed quickly.
- One or more embodiments of the present invention provide a contact mechanism in a driving tool that has good operability without causing indentations such as scratches and dents in the material to be driven.
- the driving tool is provided in the lower part of the tool body and is provided so as to be movable in the vertical direction along the injection path of the nose portion for driving the fastener.
- a member is provided.
- the lower end of the contact member protrudes beyond the tip of the nose portion.
- the contact member when the trigger is pulled, the contact member opposes the lower panel in conjunction with the valve stem of the trigger valve. You can move down! /
- the contact member since the contact member is held between the upper and lower two panels, the contact member has a cushioning property, and the stroke of the contact member when actually driven. Because it can be short, it is easy to control the force when pressing. In addition, it is constructed along the injection path of the contact member carcass part, and when moving up and down, other members do not mix with the nail so that the movement can be performed smoothly. it can Therefore, the panel load of the upper panel may be small. Therefore, the contact member can press a short stroke against the material to be driven with a small force, so that even when a fastener is driven into a soft material, the material is easily damaged and has dents. Yes.

- the injection path 6 is formed between a driver guide 8 constituting the front wall of the nose portion 4 and a wear plate 9 constituting the rear wall.
- the trigger 10 When driving the nail, the trigger 10 is pulled and the trigger valve 12 for activation is operated to send the compressed air supplied to the air compressor force to the striking mechanism and drive the leading nail by the air pressure. Force The pulling operation of the above trigger 10 effectively activates the trigger valve 12 when the contact arm 11 is actually pressed against the material to be driven by the contact arm mechanism A as the contact mechanism shown below. Configured to let you! RU
- the trigger valve 12 is the same as a conventionally known one, and when compressed air is supplied to the air compressor, the valve stem 13 is pushed downward, and the valve stem 13 is pushed upward by the trigger 10. It is actuated to start by.
- the contact arm mechanism A includes a contact arm 11 that is integrally provided with a shaft body 14 that moves in parallel with the axis of the nose portion 4, and an upper arm 15 that is an upper part of the contact arm 11.
- the shaft body 14 is formed by integrally coupling the upper shaft body 14a and the lower shaft body 14b, so that the lower shaft body 14b is provided so as not to rotate with respect to the upper shaft body 14a.
- An adjustment dial 16 is screwed onto the upper portion of the upper shaft body 14a, and the vertical position of the connecting arm 17 can be adjusted by rotating the adjustment dial 16.
- the contact arm 11 includes a lower shaft body 14b and a contact portion 18 disposed downward via a connecting arm 17 bent at a right angle from the lower portion of the lower shaft body 14b. It comprises an actuating arm 19 bent at a right angle from the middle part of the lower shaft body 14b.
- the contact portion 18 is formed separately from the wear plate 9 and is arranged so as to move up and down along the rear surface of the wear plate 9.
- the base portion 19a of the operating arm 19 is formed in a cylindrical shape, and the cylindrical portion 19a is fixed to the upper end of the lower shaft body 14b.
- panel receivers 21 and 22 are formed at positions corresponding to the upper and lower parts of the shaft body 14, and the upper panel 23 and the lower panel are interposed between the upper and lower panel receivers 21 and 22 and the operating arm 19. 24 are arranged.
- the contact arm 11 is held between the upper panel 23 and the lower panel 24 and is against the upper panel 23. It can move up and move down against the lower panel 24.

- the upper arm 15 is arranged on the upper part of the operating arm 19 so as to be movable up and down, and is urged so as to be positioned upward by the panel 25. Further, as shown in FIG. 7, the upper end of the upper arm 15 has a central portion 15a that is higher than the shoulder portions 15b on both sides.
- a trigger 10 is disposed on the upper arm 15. As shown in Fig. 2 and Fig. 3, the trigger 10 has a first contact lever 26 and a second contact lever 27 arranged so as to be pivotable about the support shaft 28 and the support shaft 29, respectively. Has been.
- the upper arm 15 is disposed between the first contact lever 26 and the second contact lever 27.
- the tip 26a of the first contact lever 26 is provided at the center 15a at the upper end of the upper arm 15, and the tip 27a of the second contact lever 27 is provided at the shoulders 15b on both sides.
- the middle of the first contact lever 26 is positioned below the valve stem 13 of the trigger valve 12 for activation, and the tip is positioned above the upper arm 15 as described above. Then, when the trigger 10 is pulled up by pushing up the tip end side of the first contact lever 26 with the upper arm 15 moved up, the first contact arm 11 pushes in the above-described nove stem 13.
- the trigger valve 12 is configured to be activated.
- the second contact lever 27 is panel-biased so as to protrude upward from the upper arm 15 in conjunction with pulling the trigger 10.
- the contact arm 11 is normally positioned below the upper panel 23, and the contact portion 18 at the tip protrudes below the nose portion 4.
- the valve stem 13 of the trigger valve 12 is pushed downward by the compressed air, so the first contact lever 26 is the valve stem.
- the tip 26a pushes the upper arm 15 against the panel 25 against the panel 25. Since the lower end of the upper arm 15 is engaged with the operating arm 19, the shaft body 14 and the contact portion 18 together with the operating arm 19 protrude further downward against the lower panel 24. Therefore, the nailer 1 does not start at this time. [0027] Further, when the trigger 10 is pulled in this manner, the upper arm 15 protrudes downward as described above. At the same time, the second contact lever 27 is rotated and the tip 27a thereof is moved to the upper arm.
- the nailer 1 can be driven by pressing the tip of the contact arm 11 against the material to be driven.
- the contact portion 18 of the contact arm 11 is pressed against the driven material.

- the first contact lever 26 pivots with the engagement with the upper end of the upper arm 15 as a fulcrum, so that the middle part pushes the valve stem 13 upward and operates the trigger valve 12 to nail Machine 1 can be activated.
- the contact arm 11 As described above, since the contact arm 11 is held between the upper and lower two panels 23, 24, the contact arm 11 itself has a cushioning property, and the stroke of the contact arm 11 when actually driving is short. It is easy to control the force when pressing. Also, since the contact arm 11 has a small stroke, and the contact arm 11 is provided independently of the injection path 6 of the nose part 4, it must rub with other nails when moving up and down. Therefore, the movement of the upper panel 23 can be smooth and the structure can be simple and lightweight. Therefore, even when a fastener is driven into a soft material, the contact arm 11 can be pressed against the material with a small force! /, So scratches and dents are difficult to attach!
- the contact arm 11 has a long stroke, the panel load increases and the pressing force also increases, so the impact when the tip of the nose portion 4 hits the surface of the workpiece is increased. In order to avoid this, it is necessary to pay attention to the pressing force, so the operation is troublesome.
- the stroke of the contact arm 11 is short, and the panel load of the upper panel 23 may be small, improving operability. To do.
- the contact arm 11 only needs to be movable in parallel with the axis of the nose portion 4, that is, along the injection path 6. Therefore, the lower shaft body 14b, the connecting arm 17, and the operating arm 19 are not limited to their shapes and connecting modes as long as they are configured to be linked in the vertical direction.
- the upper arm 15 and the actuating arm 19 may not be separate. It may be an integral structure in which the operating arm 19 is bent upward and extended. In this case, the panel 25 is unnecessary.
- the stroke of the contact arm 11 is not necessarily limited to a half of the conventional stroke. It should be longer and shorter than half.
- the contact mechanism is described as a separate contact arm from the nose portion, but a contact nose in which the tip of the nose portion serves as a contact may be used.
- the present invention is not limited to a nailing machine.
- the present invention can also be applied to a driving tool driven by electric power using only a screwdriver or a pneumatic tool.
- the present invention can be used for a contact mechanism attached to a driving tool such as a nailing machine or a screw driving machine for safety.
