Description

The present invention relates to a driving tool that protects the left and right side surfaces of a body with plate-shaped protectors and effectively prevents sliding off on an inclined work surface.

  In general, a body provided with a driving unit such as a striking mechanism inside, a nose part provided at the lower end of the body, a nose part provided at the lower end of the body, and a connecting nail through the nail feed passage to the nose part The nailing machine equipped with a magazine to be supplied is connected to the compressor via an air hose. Sometimes the driving tool is left on the roof. And when returning to work, pulling an air hose and dragging a nail driver is performed.

  Therefore, when using a material with a rough surface such as asphalt single, if the nailing machine is dragged over it, the part that contacts the work surface will wear, and the body may be damaged and scraped off. Yes, if this is repeated, there is a possibility that air leaks due to holes and becomes unusable.

For this reason, a driving tool in which a steel plate protector is attached to the side of the body has been proposed. According to this, when the driving tool is placed on the work surface, the protector comes into direct contact with the work surface, so that the body is hardly damaged.

  However, when a driving tool such as a nailing machine, a screw driving machine, or a screwing machine is placed on the roof, or when the tool is dropped by any margin during work, it may slide down from an inclined roof. There is a risk of the driving tool being damaged or falling onto the underlying device or other operator.

  In such a case, the above-mentioned protector could not prevent sliding off. For this reason, the driving tool is prevented from slipping off by being hooked on the foot.

  It is an object of the present invention to provide a driving tool that solves the above-mentioned problems, prevents surface wear, and makes it difficult to slip without having to do the trouble of hooking the driving tool on a foot. .

  In order to solve the above-mentioned problem, a driving tool according to claim 1 includes a body provided with a driving portion therein and a nose portion provided at a lower end of the body, and a fastener supplied to the nose portion is driven by the driving portion. In a driving tool to be driven, metal plate-like protectors are formed to protrude laterally on the upper and lower sides of the left and right side surfaces of the body, and when the driving tool is placed horizontally on a horizontal work surface In addition, a notch portion is formed in an opening at a portion in contact with the work surface, and the notch portion is wider on the back side than the opening side.

According to a second aspect of the present invention, the distance between the contact surface portions where the left and right upper protector cutout portions are formed is larger than the distance between the contact surface portions where the lower protector left and right cutout portions are formed. It is characterized by being formed.

According to a third aspect of the present invention, there is provided a driving tool including a body having a driving portion therein and a nose portion provided at a lower end of the body, and driving the fastener supplied to the nose portion by the driving portion. has a plate-like protector which projects from the surface, the above protector uneven portion at a portion facing against the working surface when placing the driving tool on a work surface is formed, on the uneven portion The at least one notch is formed as an opening, and the notch is formed wider on the back side than on the opening side.

  According to the first aspect of the present invention, when the driving tool is placed horizontally on a work surface such as a roof, the upper and lower protectors protect the body even if it slips, so that wear and scraping can be effectively prevented. it can.

  Further, the protector is formed with a notch at the portion that contacts the work surface when the driving tool is placed horizontally on the work surface, and the notch is located on the far side from the opening side. Since the width is wide, the angle formed between the contact surface portion of the opening and the inner surface of the notch portion is an acute angle, and when the driving tool slides down, it is easily caught on a work surface with many irregularities. Therefore, it is possible to effectively prevent the driving tool from sliding down without troublesome things such as hooking the driving tool on the foot, and improve workability. At the same time, since the driving tool is less likely to fall from the roof, the tool is less likely to break and the safety is also increased.

According to the invention which concerns on Claim 2, the distance between the contact surface parts which formed the notch part of the upper protector of right-and-left both sides becomes larger than the distance between the contact surface parts which formed the left and right notch part of the lower protector. Since the protector is worn obliquely with respect to its end surface, the angle formed between the lower surface of the protector and the inner surface of the opening is always an acute angle even if the wear proceeds. Accordingly, the effect of the notch portion being caught on the work surface is not deteriorated, and the anti-slip effect can be maintained for a long time.

According to the third aspect of the present invention, the concavo-convex portion is formed in a portion that contacts the work surface when the driving tool is placed on the work surface, and the concavo-convex portion has at least one notch opening. This notch is formed wider on the back side than on the opening side, so that the effect of catching on the work surface when the driving tool slides down can be increased, and the effect is maintained for a long time. Therefore, it is possible to effectively prevent the driving tool from sliding down.

  1 to 4, reference numeral 1 denotes a nailing machine (driving tool). This nail driver 1 includes a body 2 provided with a striking mechanism (drive unit), a grip 3 disposed rearward from the body, a nose portion 4 provided at the lower end of the body 2, and a connecting nail attached to the nose portion 4. A cylindrical magazine 5 to be supplied, and a connecting nail A (not shown) is supplied from the magazine 5 to the nose portion 4 to trigger a leading nail (not shown) sent to an injection port inside the nose portion 4 By operating the lever 6, the internal striking mechanism is actuated for launching, and the leading nail is driven into the material to be driven. Compressed air is sent from the compressor 7 to the inside of the grip 3 through the air hose 8, and the striking mechanism is operated by this compressed air. The body 2 is constituted by integrally connecting a body main body 2A and a cylinder cap 2b thereon.

  Next, metal plate protectors 10, 11 such as steel plates are formed so as to protrude laterally from the upper and lower portions of the left and right side surfaces of the body 2. That is, the upper protector 10 is an elongated plate-like member and is formed to project from the upper side of the left and right side surfaces of the body 2. That is, as shown in FIG. 1 and FIG. 3, the inner end surface thereof has a shape conforming to the shape of the upper side surface of the cylinder cap 2b, and both ends thereof are mounting surfaces for coupling the cylinder cap 2b to the body main body 2A. 12 is fixed to the body main body 2A together with the cylinder cap 2b by a bolt 14. Further, the outer end surface of the upper protector 10 is formed in a mountain shape, and a notch 13 is formed in the top, that is, a portion that contacts the work surface when the nailing machine is placed on a horizontal work surface. ing. In addition, the said notch part 13 is formed so that the back | inner side may become wider rather than the opening side.

  As shown in FIGS. 1 and 5, the lower protector 11 is formed by hanging two left and right attachment pieces 11 b below the U-shaped main body portion 11 </ b> A, and is disposed between the body 2 and the nose portion 4. The mounting piece 11 b is arranged and fixed to the front portion of the body 2 by tightening the mounting piece 11 b on the upper portion of the nose portion 4 with the left and right bolts 14. A cutout portion 15 is formed in the outer end surface of the lower protector 11, that is, a portion that contacts the work surface when the nailing machine is placed on a horizontal work surface. The notch 15 is also formed so that the back side is wider than the opening side. Triangular protrusions 16 are also provided on the left and right front portions of the lower protector 11 for protection.

  Incidentally, as shown in FIG. 4, the distance L <b> 1 between the notch portions of the upper protector 10 on both the left and right sides is formed to be larger than the distance L <b> 2 between the left and right notch portions of the lower protector 11.

  In addition, protective protrusions 17 are formed on both sides of the magazine 5.

  According to the above configuration, when the nailing machine 1 is placed horizontally on the work surface, as shown in FIG. 4, the nailing machine has the notch 13 of the upper protector 10, the notch 15 of the lower protector 11, and the magazine. It is supported at three points of the five projecting pieces 17. When the driving tool is placed horizontally on a work surface such as a roof, the upper and lower protectors protect the body 2 even if it slides, so that wear and scraping can be effectively prevented. In addition, when pulling the nail driver 1 by pulling the air hose, the grip side and the magazine side are pulled upward and floated, so that the wear is not so much.

  Further, the protectors 10 and 11 are formed with notches 13 and 15 at portions that contact the work surface when the nailing machine 1 is placed horizontally on the work surface, and the notches 13 and 15 are formed. Is wider on the back side than the opening side, the angle α formed by the contact surface portion 20 and the inner surface 18 of the notches 13 and 15 becomes an acute angle as shown in FIG. It is easy to get caught on the work surface when 1 slides down. Therefore, it is possible to effectively prevent a sliding accident without having to do the trouble of hooking the nail driver 1 on the foot, and the workability can be improved.

  Furthermore, since the possibility that the nailing machine 1 falls from the roof is reduced, the possibility of damaging the tool is low and the safety is also improved.

  Moreover, since the distance L1 between the cutouts 13 of the upper protector 10 on both the left and right sides is larger than the distance L2 between the cutouts 15 of the lower protector 11, the upper and lower protectors 10, 11 The contact surface portion 20 is worn obliquely with respect to the end surface. Therefore, as shown in FIG. 6B, the wear surface (contact surface portion) 20 is formed obliquely in the thickness direction. When this is viewed in a plane, it is as shown in FIG. 2A, and the angle β formed by the upper surface 19 of the opening and the wear surface (contact surface portion) 20 is an acute angle as described above. Further, when viewed from the opening side, it is as shown in FIG. Even if wear progresses, the angle γ formed by the upper surface 19 of the protectors 10 and 11 and the inner surface 18 of the opening is always an acute angle. Therefore, even if the protectors 10 and 11 are worn, the openings 13 and 15 are always formed with three acute angles α, β, and γ. The anti-slip effect of the opening can be maintained for a long time.

  As described above, the anti-slip effect can be obtained by the metal protectors 10 and 11, so that it is not necessary to provide a special anti-slip component. Therefore, the driving tool does not increase in weight or size.

  In addition, the said structure is not limited only to a nailing machine. For example, the present invention can be applied not only to nails but also to driving tools such as screw driving machines, screwing machines, and electric tools for driving fasteners such as screws and parallel pins.

  In order to obtain the anti-slip effect, the plate-shaped protector may be configured such that an uneven portion is formed in a portion that contacts the work surface when the driving tool is placed on the work surface. In this case, since the driving tool is easily caught on the work surface when it slides down, it is possible to effectively prevent the driving tool from sliding down. Furthermore, the uneven portion has at least one notch formed as an opening, and by forming the back side wider than the opening side, the catching effect on the work surface is greater than in the case of only the uneven portion, Moreover, the effect can be maintained for a long time.
