Description

  The present invention relates to a manual nail driver that can easily drive nails without using a large-scale device such as an air compressor.

  As a conventional manual nailing device (a nailing device that can be driven only by human power), in Patent Document 1, a gripping portion is provided on one end side, and a chain nail storage portion is provided on the inside from the middle portion toward the other end side. The striking part is installed in the orthogonal direction at the tip of the provided plate main body, and a piston body having a rod facing the head of the tip of the chain nail is provided inside the striking part at the other end side. Describes a hammer in which a straight nail feed hole is formed from the rod through a nail. Thereby, it is not necessary to drive a part of the nail in advance, and the working efficiency can be improved.

  Patent Document 2 describes a nailing device in which a piston and a spring with a handle are attached to a cylinder and a nail case is attached to the lower part of the cylinder. Thereby, it is supposed that the nail driver which can drive in a nail by operating a handle can be provided.

  However, since the hammer of Patent Document 1 is used by swinging down the whole, it is not always possible to accurately drive the nail at the position where the nail is aimed, and the nail may be driven obliquely. If this hammer is accidentally dropped, the nail may be driven out by the impact, and there is a doubt about safety.

  On the other hand, the nailing device of Patent Document 2 has a configuration in which a moment of force centering on the tip of the cylinder and the wrist is likely to occur during the nailing operation, and is very easy to wobble. If the nailing device wobbles during the nailing operation, the nail that is being driven may be bent or tilted from the target. There are also doubts about safety when dropped.

  The present invention has been made to solve the above-described problems, and provides a manual nail driver that can accurately drive a nail into a target position. It is another object of the present invention to provide a manual nailing device that can prevent nails from being damaged. Furthermore, the present invention provides a safe manual nail driver that does not allow a nail to be launched without permission even when an impact is accidentally applied.

  The above-described problems include a magazine loaded with a nail, a nose provided with a nail injection port at the front end, a striking piston for striking a nail sent from the magazine to the nose from the rear and launching from the nail ejection port, and a striking piston This is solved by providing a manual nailing device having a manual hammer for striking the striking piston from the rear side and attached to the outer peripheral surface of the cylinder so as to be movable back and forth. As a result, it is possible to provide a manual nail driver that can accurately drive a nail at a target position and has less wobble and damage. Also, with this manual nailing device, not only the nail but also the plate on which the nail is driven can be beaten at the same time, so the finish is beautiful. Furthermore, the nail head can be struck repeatedly as long as it is flush with the surface of the plate on which the nail is driven.

  The manual hammer is preferably a cylindrical body that holds the outer peripheral surface of the cylinder. This not only prevents the manual hammer from falling off the cylinder, but also allows the manual hammer to have a shape that is easy to grip. In order to improve the adhesion between the manual hammer and the finger, it is preferable to form irregularities on the outer peripheral surface of the manual hammer.

  It is also preferable that a straight long hole along the longitudinal direction of the cylinder is provided on the cylinder peripheral wall. Thereby, the operability and safety of the manual nailer can be further improved. At this time, it is more preferable that a knob is fixed to the striking piston and the knob protrudes from the elongated hole to the outside of the cylinder.

  It is also preferable that a nail feeding means is provided which can supply the nail loaded in the magazine to the nose and press the striking piston when the striking piston enters the nose. As a result, not only can the nail feed from the magazine to the nose be performed automatically, but also the malfunction of the manual nailer can be prevented. It is also preferable that a locking means for fixing the manual hammer to the nose or the cylinder is provided. As a result, it is possible to prohibit the longitudinal movement of the manual hammer and the striking piston.

  It is also preferable that an upright piece is suspended from the upper surface of the nose. Thereby, it is also possible to use the manual nailing device as a fitting device for the tongue joint plate. This standing piece is more preferably detachable.

  It is also preferable that an attachment can be attached to the tip of the nose, and the shape of the tip of the nose can be changed by attaching or detaching or replacing the attachment. Thereby, the shape of the tip of the nose can be selected according to the shape of the material to be nailed, and the manual nailing device can be used for a wide range of applications.

  As described above, the manual nail driver of the present invention makes it possible to accurately drive a nail at a target position. It is also possible to prevent the nails from being broken. Furthermore, it is also possible to provide a manual nailing device that does not allow the nail to be unnecessarily driven even if an impact is applied accidentally. For this reason, it is possible to provide a manual nailing device excellent in operability and safety. Furthermore, it is a drawback of automatic nailers that use air compressors in combination with continuous noise generation, dust rising due to air, troublesomeness when handling air hoses, and adjustment of driving force. Deterioration of the quality due to the inability to do so (In the case of automatic nailers, nails can only be driven once and the momentum is too high. In many cases, there is a gap in the nail head, and when the base wood is hard, the nail head was often looked into.).

  As shown in FIG. 1, the manual nailer 10 of the present invention includes a magazine 20, a nose 30, a striking piston 40, a cylinder 50, and a manual hammer 60. As shown in FIGS. 2 to 4, the manual nail driver 10 is used with a nose tip abutted on a place where a nail is to be driven. For this reason, it is possible to accurately drive the nail at a target position. Further, the manual nailing device 10 is configured such that when the hammer 60 is driven toward the nose side with the striking piston 40 being pulled rearward, the nail is driven out, and there is a momentum for hitting the manual hammer 60. The better, the better. For this reason, the manual nailing device 10 can also adjust the force of nail driving.

  Each part of the manual nailer 10 will be described. As shown in FIG. 5, the magazine 20 is attached to the lower side of the nose 30 so as to be perpendicular to the longitudinal direction of the cylinder 50, and when operating the manual nailing device 10, If you are a good person, you can usually grip with your left hand). Further, the magazine 20 is configured such that the lid 21 slides up and down, and a plurality of nails can be loaded therein. In this embodiment, a connecting nail 70 (FIGS. 2 to 4) in which a plurality of nails are connected in a band shape with glue is loaded inside the magazine. The type of nail to be used is not particularly limited, and for example, nails (general nails 71, cup nails 72, T-shaped nails 73, mat nails 74, finish nails 75) as shown in FIG. 6 can be used. .

  On the back side of the lid 21 (side facing the inside of the magazine), nail feeding means 80 is provided as shown in FIG. The nail feeding means 80 is not particularly limited as long as it can supply the nail to the nose 30, but it is preferable to use an elastic body. In this embodiment, the coil spring 81 is accommodated in the groove 22 provided on the back side of the lid 21. A plate-like push-up member 82 is fixed to the upper end portion of the coil spring 81, and the upper end surface of the push-up member 82 comes into contact with the lower end surface of the connecting nail 70.

  As shown in FIG. 1, the nose 30 is provided with a nail injection port 31 at the front end. Nails are supplied from the magazine 20 into the nose. When the nail supplied into the nose is struck from behind by the striking piston 40, the nail is peeled off from the lower nail and ejected from the nail exit port 31. The shape of the tip of the nose can be easily changed by mounting the attachment 90 shown in FIG. 8 or the attachment 91 shown in FIG. The attachment 90 can be suitably used when it is desired to drive a nail perpendicular to the planar portion, and the attachment 91 can be suitably used when it is desired to drive a nail into a corner portion.

  As shown in FIG. 2, the striking piston 40 uses a rod-like one, and receives a blow from the manual hammer 60 at the rear end 41 and hits the nail supplied into the nose at the front end 42. It is like that. When the striking piston 40 enters the nose, it receives a pressing force from the nail feeding means 80 via the connecting nail 70 (FIG. 4). For this reason, when one end of the striking piston 40 enters the inside of the nose, the striking piston 40 does not move to the extent that the manual nailing device 10 is shaken.

  As shown in FIG. 1, a rod-like knob 43 is suspended from the outer peripheral surface of the striking piston 40. The knob 43 protrudes from the long hole 51 provided in the cylinder peripheral wall to the outside of the cylinder. For this reason, the striking piston 40 can be moved from the outside of the cylinder by moving the knob 43 back and forth. For this reason, the manual nailing device 10 is in a state where the nailing can be performed again when the knob 43 is pulled backward after the nail driving is completed. In other words, as long as the knob 43 is not pulled backward, the nail is not driven no matter how much the manual hammer 60 is hit against the striking piston 40, so that misfire of the nail can be prevented.

  As shown in FIG. 5, the cylinder 50 extends rearward of the nose and is parallel to the direction in which the nail is driven out. The shape of the cylinder 50 is not particularly limited as long as it can guide the manual hammer 60, but is preferably a prismatic shape. Thereby, the manual hammer 60 can be easily moved back and forth without rotating in the circumferential direction of the cylinder 50. In this embodiment, the cylinder 50 is formed in a square cylinder, and a straight long hole 51 is provided on the side surface.

  The manual hammer 60 is slidably attached to the cylinder 50 as shown in FIGS. 2 to 4, and can be moved forward and backward by grasping with one hand (usually the right hand if right-handed). ing. The center of gravity G of the manual hammer 60 is preferably as close as possible to the extension line L of the striking piston 40 as shown in FIG. If the center of gravity G is away from the extension line L, when the manual hammer 60 is moved back and forth, a moment of force occurs around the tip of the nose, and the manual nailing device 10 moves in the direction of the arrows A and B. This is because it becomes easier to rotate. The distance between the center of gravity G and the extension line L is usually 5 cm or less, although it varies depending on the weight balance of the manual nailer 10. The distance between the center of gravity G and the extension line L is more preferably 3 cm or less, and further preferably 2 cm or less. It is optimal if it is 1 cm or less. In the present embodiment, the distance between the center of gravity G and the extension line L is 0 cm, and the center of gravity G moves on the extension line L.

  The shape of the manual hammer 60 is not particularly limited as long as it can be fitted to the cylinder 50, but as shown in FIGS. 2 to 4, it may be a cylindrical body that can hold the cylinder 50. preferable. In this embodiment, the manual hammer 60 is formed in a square cylinder, and can hold the square columnar cylinder 50. Manual hammer 60 is designed so that once it is advanced to the position of FIG.

  As shown in FIGS. 2 to 4, an impacting body 61 for hitting the rear end portion 41 of the impacting piston 40 is provided on the front end side of the manual hammer 60. In this embodiment, the striking body 61 is provided by making a pair of holes in the peripheral wall of the manual hammer 60 and inserting a rod body that becomes the striking body 61 into the pair of holes. Both ends of this rod are fixed with bolts 62. The bolt 62 can also be used for locking means described later. Moreover, the intermediate part of the rod is formed in a flat shape so that the rear end 41 of the striking piston 40 can be easily hit. The striking body 61 is guided to the long hole 51 when the manual hammer 60 is moved back and forth. The striking body 61 also has a function as a stopper that prevents the manual hammer 60 from falling out behind the cylinder (FIG. 2).

  The weight of the manual hammer 60 is preferably 200 g or more. This is because if the weight is less than 200 g, the inertia of the manual hammer 60 becomes too small and a great deal of labor may be required for nailing. The weight of the manual hammer 60 is more preferably 500 g or more, and further preferably 600 g or more. The weight of the manual hammer 60 is preferably 1500 g or less. This is because if this weight exceeds 1500 g, the manual nail driver 10 may become too heavy and difficult to operate. The weight of the manual hammer 60 is more preferably 1000 g or less, and further preferably 700 g or less. In this embodiment, the weight of the manual hammer 60 is about 650 g.

  As shown in FIG. 10, the manual hammer 60 can be fixed to the cylinder 50 by the lock means 100. In this embodiment, the locking means 100 is provided by attaching a hook 101 to a bolt 102 fixed to the cylinder 50. In this case, the manual hammer 60 is fixed to the cylinder 50 when the hook 101 is rotated in the direction of arrow C and hooked on the bolt 62. Moreover, the position of the manual hammer 60 is fixed in a state where the manual hammer 60 is pushed to a position where it cannot be advanced any further. For this reason, when the manual hammer 60 is fixed to the cylinder 50, the striking piston 40 is also fixed to the cylinder 50.

  As shown in FIG. 11, the manual nailing device 10 of the present invention can also be used as a fitting tool for the tongue joint plate 111 by extending a standing piece 92 on the upper surface of the nose. That is, the tongue joint plate 111 can be easily fitted by hitting the manual hammer 60 backward while the upright piece 92 is applied to the end surface of the tongue joint plate 111. In this embodiment, the standing piece 92 is provided by attaching an L-shaped angle to the upper surface of the nose.
