FIG. 1 shows an embodiment of the present invention.
This will be described with reference to FIG. FIG. 1 shows a nailing machine 1 of the present embodiment. The nailing machine 1 includes a main body 2 having a substantially prismatic shape, a nail driving section 3 protruding from the lower surface of the main body 2, and a nail feed section 4 provided on a side of the nail driving section 3. A handle portion 5 protruding laterally from a side portion of the main body 2, and a substantially cylindrical nail magazine 6 attached in a bridging manner between the handle portion 5 and the nail feed portion 4. I have.

The nailing machine 1 of this embodiment is provided with a scratch preventing member for preventing the floor material W from being damaged when the nailing machine 1 is placed on the floor material W for driving nails. It has features in terms of form and its arrangement, and the internal structure and functions of the main body 2, the nail driving section 3, the nail feed section 4, the handle section 5, the nail magazine 6, and the like are particularly different from the conventional configuration. The description and illustration are omitted because no change is required.

The main body 2 has a substantially prismatic shape having a back surface 2a and both side surfaces 2b, 2b. The main body 2 is provided with substantially U-shaped scratch prevention members 11, 12 at two front and rear positions so as to straddle the back surface 2a and the side surfaces 2b, 2b. The scratch prevention members 11 and 12 are made of rubber having a certain elasticity and a function as a non-slip material.

Next, the nail magazine 6 has a substantially cylindrical shape for loading a connecting nail wound in a coil shape, and its bottom surface 6a has a substantially circular shape. The side surfaces 6b of the nail magazine 6, which are opposed to the floor material W when the nailing machine 1 is placed in a horizontal position, are also provided on the side surfaces 6b.
4 is attached. The both scratch prevention members 13,
14 is also made of rubber like the scratch prevention members 11 and 12. The both damage prevention members 13 and 14 have a substantially L-shape, and are attached across the corner between the bottom surface 6a and the side surface 6b.

FIG. 3 shows a state in which the nailing machine 1 is placed horizontally. As shown in the drawing, when the nailing machine 1 is placed horizontally, one side surface 2b of the main body 2 and the side surface 6b of the nail magazine 6 are directed to the floor material W, and the scratch prevention members 11 and 12 of the main body 2 The side surfaces 14b of the scratch prevention member 14 of the side surfaces 11b and 12b and the nail magazine 6 abut against the floor material W. As described above, in the case of the horizontal installation, the damage prevention members 11 and 12 of the main body 2 and the damage prevention member 14 of the nail magazine 6 are supported at three points.
1 and 12 and side surface portions 11b and 12b and scratch prevention member 14
Only the side surface portion 14b abuts on the flooring material W, thereby preventing the flooring material W from being damaged and preventing the floor material W from slipping horizontally. In addition, if the nailing machine 1 is laid horizontally in a direction opposite to the above, the side portions 11b and 12b on the opposite side to the scratch prevention members 11 and 12 and the side portion 13b of the scratch prevention member 13 become floor material W. Connect to ground.

In the case of the horizontal installation, the side portions 11b and 12b of the anti-scratch members 11 and 12 attached to the front and rear two places of the main body 2 and the anti-scratch members 14 of the nail magazine 6 are provided.
(Or 13), the side surface 14b (or 13b) is grounded to the floor material W, and the center of gravity of the nailing machine 1 is located inside the triangle formed by these three points. , 12, 13, and 14 are set,
Other portions (for example, the tip of the handle portion 5 or the tip of the nail driving portion 3) do not come into contact with the floor material W, and stable three-point support is realized.

Next, on the bottom surface 6a of the nail magazine 6, the above-mentioned both scratch preventing members 13, 14 (bottom portions 13a, 14a) are provided.
In addition, a scratch prevention member 15 is attached. The nailing machine 1 can be self-supported vertically by grounding the three scratch preventing members 13, 14, 15 to the floor material W. This vertically placed state is shown in FIG. In the case of this vertical installation, the positions and shapes (dimensions) and the like of the damage preventing members 13, 14, 15 are set so that the tip of the nail driving portion 3 is slightly floated as shown in the figure. For this reason, in the state where the nailing machine 1 is placed vertically, the contact arm provided at the tip of the nailing portion 3 so as to be able to move up and down does not come into contact with the floor material W and move upward. I have. Note that this contact arm has a function of a safety device for validating the pulling operation of the trigger by pressing the nail against the nail driving member and moving it upward during the nail driving operation. Since this contact arm is a conventionally known technique, it will not be described in detail.

The scratch preventing member 15 is mounted at a position corresponding to a vertex of an isosceles triangle having a base line connecting the bottom surfaces 13a and 14a of the scratch preventing members 13 and 14. In the state where the nailing machine 1 is placed vertically, the position and the shape (dimensions) of the scratch preventing members 13, 14, 15 are set so that the vertical line passing through the center of gravity of the nailing machine 1 intersects the isosceles triangle. Therefore, the nail driver 1 is stabilized in the vertically installed state.

According to the nailing machine of the present embodiment configured as described above, not only the side surface 2b of the main body 2 but also the side surfaces of the nail magazine are prevented from being damaged by the damage preventing members 13 and 14 (side surface portions 13b and 13b).
14b) is attached, so that even if the nailing machine 1 is placed horizontally, the nail magazine 6 does not damage the floor material. Since the scratch prevention members 11, 12, 13, and 14 are attached to both side surfaces of the main body 2 and the nail magazine 6, the floor material W is damaged even if any side surface is placed horizontally toward the floor material W. Never.

At three places on the bottom surface 6a of the nail magazine 6, bottom surface portions 13a, 14a of the scratch prevention members 13, 14 are provided.
And the damage prevention member 15 are located, the nailing machine 1 can vertically place the three points on the floor material W by touching the three points, and also in this case, the rubber damage prevention member is used. 1
Since only 3, 14, 15 are grounded, the floor material W is not damaged. Also, in the case of this vertical installation, the scratch prevention member 1
Since three points are supported by 3, 14, and 15, and a vertical line passing through the center of gravity of the nailing machine 1 intersects the inside of the triangle having the three points as vertices, it can be stably placed vertically.

Further, the scratch preventing members 11 and 12 attached to the main body 2 are substantially U-shaped and have rear portions 11a and 12a.
have. According to this, for example, when the user lowers the nailing machine 1 on the flooring W in a state of being held upside down by holding the air hose connected to the tip of the handle portion, first, the scratch preventing members 11, 12 rear portions 11a, 1
2a comes into contact with the floor material W, and thereafter, during the time until the nailing machine 1 falls down to the horizontal position, the side portions 11b, 12b (or, alternatively, the scratch prevention members 11, 12). Since the joints between the back portions 11a and 12a and the side portions 11b and 12b (the corners of the damage preventing members 11 and 12) come into contact with the floor material W, the floor material W is reliably prevented from being damaged. If it is placed in the horizontal position, the damage preventing members 11, 12, 1
4 (or 13) prevents the floor material W from being damaged.

Various modifications can be made to the embodiment described above. For example, the anti-scratch members 11 and 12 attached to the main body 2 are substantially U-shaped, and one anti-scratch member 11 and 12
2b, the rear surface 2a and the side surface 2b
The side may be separated. In addition, the configuration in which the substantially U-shaped scratch prevention members 11 and 12 are attached to the front and rear two places of the main body 2 has been illustrated, but the side surface 2b and / or the rear surface 2a of the main body 2 are, for example, as shown in FIG. It is good also as a structure which attaches the damage prevention members 16 and 17 which have a long strip shape.

Furthermore, although each of the damage preventing members 11 to 17 is made of rubber, other materials that can prevent the floor material W from being damaged, such as cloth or wood, may be used as a material. In the illustrated embodiment, each of the scratch preventing members 11 to 16 is prepared separately from the main body 2 or the nail magazine 6 and is attached to a predetermined position. When the members are made of plastic, they may be integrally formed on the case surface of the main body 2 or integrally formed on the side surface 6b and the bottom surface 6a of the nail magazine 6.
