DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a nailing machine 1 according to this embodiment. This nail driving machine 1 includes a main body 2 having a generally prismatic body shape, a nail driving portion 3 provided so as to protrude from the lower surface of the main body 2, and a nail feeding portion 4 provided on a side portion of the nail driving portion 3. A handle portion 5 provided so as to protrude from the side of the main body 2 to the side, and a substantially cylindrical nail magazine 6 attached between the handle portion 5 and the nail feed portion 4 in a spanning manner. Yes.
[0008]
The nailing machine 1 according to the present embodiment is provided with a damage preventing member mounting form for preventing the floor material W from being damaged when the nail driving machine 1 is placed on the floor material W into which the nail is driven, and It has characteristics in terms of arrangement and the like, and the internal structure and functions of the main body 2, the nail driving portion 3, the nail feeding portion 4, the handle portion 5, the nail magazine 6 and the like need to be changed especially compared to the conventional configuration. Therefore, the description and illustration are omitted.
[0009]
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 preventing members 11 and 12 at two front and rear positions so as to straddle the back surface 2a and both side surfaces 2b and 2b. The both scratch preventing members 11 and 12 are made of rubber having a certain elasticity and a function as an anti-slip material.
[0010]
Next, the nail magazine 6 has a substantially cylindrical shape for loading a connection nail wound in a coil shape, and its bottom surface 6a has a substantially circular shape. The scratch preventing members 13 and 14 are also attached to the side surface 6b of the nail magazine 6 and facing the floor material W when the nailing machine 1 is placed horizontally. Both the damage preventing members 13 and 14 are made of rubber, like the damage preventing members 11 and 12.
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.
[0011]
FIG. 3 shows a state in which the nailing machine 1 is placed horizontally. As shown in the figure, when the nailing machine 1 is placed horizontally, one side surface 2b of the main body 2 and a side surface 6b of the nail magazine 6 are directed to the floor material W, so that the scratch preventing members 11 and 12 of the main body 2 are not damaged. The side surface portions 11 b and 12 b and the side surface portion 14 b of the scratch-preventing member 14 of the nail magazine 6 abut against the flooring W.
As described above, in the case of the horizontal placement, the scratch prevention members 11 and 12 of the main body 2 and the scratch prevention member 14 of the nail magazine 6 are supported at three points. In this case, the side portions of the scratch prevention members 11 and 12 are also supported. 11b, 12b and only the side surface portion 14b of the scratch preventing member 14 are brought into contact with the flooring W, thereby preventing the flooring W from being scratched and preventing slipping in the horizontal state.
If the nailing machine 1 is placed sideways in the direction reversed from the above, the side surface portions 11b, 12b on the opposite side of the scratch preventing members 11, 12 and the side surface portion 13b of the scratch preventing member 13 become the floor material W. To ground.
[0012]
Further, in the case of the horizontal installation, the side portions 11b and 12b of the scratch preventing members 11 and 12 attached to the front and rear two places of the main body 2 and the side portion 14b of the scratch preventing member 14 (or 13) of the nail magazine 6 are provided. (Or 13b) is grounded to the flooring W, and the position of each scratch preventing member 11, 12, 13, 14 is such that the center of gravity of the nailing machine 1 is located inside the triangle formed by these three points. Therefore, stable three-point support can be realized without contacting other parts (for example, the tip of the handle portion 5 or the tip of the nail driving portion 3) with the floor material W. ing.
[0013]
Next, the scratch preventing member 15 is attached to the bottom surface 6a of the nail magazine 6 in addition to the both scratch preventing members 13, 14 (bottom surface portions 13a, 14a). By making these three scratch-preventing members 13, 14, and 15 contact the floor material W, the nailing machine 1 can be made to stand vertically. This vertically placed state is shown in FIG.
In the case of this vertical installation, as shown in the drawing, the positions and shapes (dimensions) of the scratch preventing members 13, 14, 15 are set so that the tip of the nail driving portion 3 is slightly lifted. For this reason, in a state where the nailing machine 1 is placed vertically, the contact arm provided at the tip of the nail driving portion 3 so as to be movable up and down does not contact the floor material W and move up. Yes. The contact arm has a function of a safety device for making the trigger pulling operation effective by pressing the nail driving material 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.
[0014]
The scratch preventing member 15 is attached at a position corresponding to the apex of an isosceles triangle having a base connecting the bottom surface portions 13a and 14a of the scratch preventing members 13 and 14. In a state where the nailing machine 1 is placed vertically, the positions and shapes (dimensions) of the scratch preventing members 13, 14, 15 and the like are such that the vertical line passing through the center of gravity of the nailing machine 1 intersects the isosceles triangle. Thus, the vertical position of the nailing machine 1 is stabilized.
[0015]
According to the nailing machine of the present embodiment configured as described above, the scratch preventing members 13 and 14 (side portions 13b and 14b) are attached not only to the side surface 2b of the main body 2 but also to the side surface of the nail magazine. Therefore, the floor material is not damaged by the nail magazine 6 even when the nailing machine 1 is placed horizontally. Since the scratch-preventing 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 sideways toward the floor material W. There is nothing.
[0016]
In addition, since the bottom surface portions 13a and 14a of the scratch preventing members 13 and 14 and the scratch preventing member 15 are located at three locations on the bottom surface 6a of the nail magazine 6, the nail driving machine 1 relates these three points. The floor material W can be grounded and placed vertically, and in this case as well, only the rubber scratch-preventing members 13, 14, 15 are grounded, so that the floor material W is not damaged. Also, in the case of this vertical installation, three points are supported by the scratch-preventing members 13, 14, and 15, and the 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. Can be placed vertically in a stable state.
[0017]
Further, the scratch preventing members 11 and 12 attached to the main body 2 are substantially U-shaped and have back portions 11a and 12a. According to this, for example, when the user holds the air hose connected to the tip of the handle part and hangs the nail driver 1 upside down on the floor material W , as shown in FIG. The damage prevention member 11, 12 a of the damage prevention member 11, 12 abuts against the flooring W, and then the nailing machine 1 falls sideways to the sideways state. 11 and 12 side surface portions 11b and 12b (or the joint portions of the back surface portions 11a and 12a and the side surface portions 11b and 12b (corner portions of the scratch preventing members 11 and 12)) are in contact with the floor material W. The damage of the material W is reliably prevented. If it becomes a horizontal installation state, as mentioned above, the damage prevention member 11, 12, 14 (or 13) will prevent the flooring W from being damaged.
[0018]
Various modifications can be made to the embodiment described above. For example, the scratch preventing members 11 and 12 attached to the main body 2 are substantially U-shaped, and a single scratch preventing member 11 and 12 is illustrated as straddling between the back surface 2a of the main body 2 and both side surfaces 2b and 2b. The back surface 2a side and the side surface 2b side may be separated.
In addition, the configuration in which the substantially U-shaped scratch preventing members 11 and 12 are attached to the front and rear two places of the main body 2 is illustrated. However, the side surface 2b and / or the rear surface 2a of the main body 2 are, for example, front and rear as shown in FIG. It is good also as a structure which attaches the damage prevention members 16 and 17 which make a long strip shape.
[0019]
Furthermore, although each damage preventing member 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 raw material.
In the illustrated embodiment, the scratch preventing members 11 to 16 are prepared separately from the main body 2 or the nail magazine 6 and are mounted at predetermined positions, respectively. When the members are made of plastic, these may be integrally formed on the case surface of the main body 2 and may be integrally formed on the side surface 6b or the bottom surface 6a of the nail magazine 6.
