Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor material having a convex portion and a concave portion substantially at the center of both end faces, and stopping at an angle near the upper corner of the convex portion of the floor material. The present invention relates to a driving machine for driving a tool. 2. Description of the Related Art FIG. 3 shows an example in which a conventional driving machine is used to drive a floor material which is a mounting material in flooring construction, and FIG. FIG. The floor member 10 has a convex portion 11 and a concave portion (not shown) substantially at the center of both end surfaces, and the stopper 8 is driven into the corner portion 12 of the convex portion 11 at an angle (usually approximately 45 °), It fits into the recess of the next floor material 10. At the time of flooring work, a nose cap 6a dedicated to flooring work is attached to the tip of the push lever 5 to perform work. At this time, the projection 13 at the tip for guiding the nose cap 6a to the corner 12 of the floor material 10
On the axis 17. That is, the center line of the nose cap 6a coincided with the axis 17 of the injection port 4. Reference numeral 1 denotes a driving machine main body, 2 denotes a body containing a cylinder (not shown), a compressed air storage chamber and the like, 9 denotes a driven member to which a floor member 10 is stopped via a stopper 8, and 14 denotes a drive integrated with a piston. Bit 16 is a magazine. FIG. 5 shows an example of the state of the stopper 8 in the injection port 4. Stopper 8 in injection port 4
Does not always coincide with the direction of the axis 17 of the injection port 4 and may be installed in an inclined state.
In this case, the tip of the stopper 8 is disengaged from the corner 12 of the floor member 10 and is driven into the upper surface of the floor member 10 (FIG. 6).
For example, the floor material 10 may be shifted toward the convex portion 11 and driven. If the stopper 8 is driven into the upper surface of the floor member 10, the floor member 10 becomes unusable, and it is necessary to remove the stopper 8 and the floor member 10 and re-attach a new floor member 10. An object of the present invention is to provide a driving machine which eliminates the above-mentioned disadvantages of the prior art and can improve the finish and workability of flooring construction. The above object can be attained by providing a projection at the tip of a nose cap for guiding the tip of an injection portion to a corner of a floor material, offset from the axis of the injection port. In the driving machine configured as described above, when driving the stopper into the floor material, a dedicated nose cap is attached to the tip of the push lever, and the projection at the tip of the nose cap is projected. By displacing the stopper from the axis of the outlet, it is possible to prevent the stopper from being driven into the upper surface of the floor member due to the inclination of the stopper in the outlet. FIG. 1 shows an example in which a fastener 8 is driven into a floor member 10 during flooring by a driving machine according to the present invention, and FIG. 2 is an enlarged view of the tip of an injection part 3. . FIG.
In the flooring construction, the work of attaching the floor member 10 is performed by using the convex portion
There is a structure in which the stopper 8 is driven into the corner 12 of the upper surface of the projection 11 at an angle (usually approximately 45 °), and is fitted into the recess of the next floor material 10. For this reason, the driving machine attaches a special nose cap 6 made of an elastic body such as rubber or plastic to the tip of the push lever 5 usually made of steel in order to drive the stopper 8 at an accurate point. It is configured to be guided by using the upper surface corner 12 of the convex portion 11 of the floor member 10. The driving machine always pushes the push lever 5, which is pressed below the driving machine main body 1 by a spring (not shown), onto the floor member 10, pushes up the push lever 5, and further pulls the trigger 15 to strike the stopper 8. Has become. Alternatively, the trigger 15 is first pulled, and then the push lever 5 is pushed up to strike the stopper 8. When the floor material is stopped by the driving machine of the present invention, as shown in FIG. 1, a nose cap 6 is provided at the tip of the push lever 5 so that the axis 17 of the injection port and the axis 20 of the handle are aligned. Since the mounting plane is mounted so as to be parallel to the straight line which is the corner 12 of the floor material 10, the driving machine body 1 is inclined laterally (usually approximately 45 °), and the projection 13 at the tip of the nose cap 6 is formed. Is applied to the corner 12 of the floor member 10 to perform the driving operation. At this time, as shown in FIG. 2, the convex portion 13 at the tip of the nose cap 6 is approximately 0.5 to 2.0 in the direction perpendicular to the axis 17 of the injection port and toward the end of the floor material 10.
When the stopper 8 is provided with a distance of mm (dimension n), the stopper 8 is driven into the floor member 10 with a corresponding displacement, so that the stopper 8 is
Can be prevented from being driven into the upper surface of the floor member 10 even if the member is inclined. That is, according to the present invention, the tip of the stopper 8 is driven into the convex portion 11 side of the floor member 10, and the probability of being driven into the upper surface of the floor member 10 is reduced. According to the present invention, the nose cap for guiding the tip of the injection port to the corner of the projection of the floor material is mounted on the tip of the push lever and the projection of the tip of the nose cap is provided. Is shifted in the direction perpendicular to the end of the floor material from the axis of the injection port, the probability that the stopper is driven into the upper surface of the floor material is reduced, and the finish in the floor material fixing work can be improved. .
