Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving tool for driving a stopper at an angle near a corner of the upper surface of a convex portion of a floor material having a convex portion and a concave portion at both ends thereof. .

[0002]

2. Description of the Related Art FIG. 3 shows an example in which a floor material, which is a mounting material in a flooring construction, is driven by a conventional driving machine, and FIG. 4 is a partially enlarged view of the tip of the injection part 3 of FIG. Show. The floor member 10 has a convex portion 11 and a concave portion (not shown) at substantially central portions of both end surfaces, and a stopper 8 is driven at an angle (usually approximately 45 °) with respect to a corner portion 12 of the convex portion 11, It is adapted to fit in the recess of the next floor material 10. At the time of flooring construction, a nose cap 6a dedicated to flooring construction is attached to the tip of the push lever 5 to perform the work. At this time, the convex portion 13 at the tip for guiding the nose cap 6a to the corner portion 12 of the floor member 10 has the injection port 4
Was on axis 17. That is, the center line of the nose cap 6a and the axis line 17 of the injection port 4 were aligned. In addition, 1 is a driving machine main body, 2 is a body including a cylinder (not shown), a compressed air accumulating chamber, etc., 9 is a driven material to which a floor material 10 is stopped by a stopper 8, and 14 is a drive integrated with a piston. Bit 16 is a magazine.

[0003]

FIG. 5 shows an example of the state of the stopper 8 in the injection port 4. A stopper 8 in the injection port 4
The longitudinal direction of 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 comes off the corner 12 of the floor material 10 and is driven into the upper surface of the floor material 10 (FIG. 6).
The floor material 10 may be driven into the convex portion 11 side while being displaced. If the stopper 8 is driven into the upper surface of the floor material 10, the floor material 10 cannot be used, and it is necessary to remove the stopper 8 and the floor material 10 and re-tighten the new floor material 10. It is an object of the present invention to provide a driving machine which eliminates the above-mentioned drawbacks of the prior art and can improve the finish and workability of flooring construction.

[0004]

The above object can be achieved by providing a convex portion of the tip of the nose cap for guiding the tip of the injection portion to the corner of the floor member, offset from the axis of the injection port.

[0005]

In the driving machine constructed as described above, when driving the stopper on the floor material, a dedicated nose cap is attached to the tip of the push lever, and the convex portion of the tip of the nose cap is attached to the axis line of the injection port. By providing the stoppers in a staggered manner, it is possible to prevent the stopper from being driven into the upper surface of the floor material due to the inclination of the stopper in the injection port.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example in which a stopper 8 is driven into a floor material 10 in flooring construction by a driving machine according to the present invention, and FIG. FIG.
In the installation work of the floor material 10 in the flooring work, the convex portion 11 is provided at the substantially central portion of the end surface of the floor material 10.
The structure is such that the stopper 8 is driven into the corner 12 on the upper surface of the convex portion 11 at an angle (usually about 45 °) and fitted into the concave portion of the next floor member 10. For this reason, in the driving machine, in order to drive the stopper 8 at an accurate point, a dedicated nose cap 6 which is usually made of an elastic body such as rubber or plastic is attached to the tip end of the push lever 5 which is usually made of steel. It is attached by utilizing it, and has a structure that guides to the upper corner 12 of the convex portion 11 of the floor material 10. Then, in the driving machine, the push lever 5 which is constantly pressed to the lower side of the driving machine main body 1 by a spring (not shown) is pressed against the floor material 10 to push up the push lever 5 and pull the trigger 15 to drive the stopper 8. Has become. Alternatively, the trigger 15 is first pulled, and then the push lever 5 is pushed up to drive the stopper 8.

When the floor material stopping work is carried out by the driving machine of the present invention, the nose cap 6 is attached to the tip of the push lever 5 as shown in FIG. Since the mounting plane is attached so as to be parallel to the straight line which is the corner 12 of the floor member 10, the driving tool body 1 is tilted in the lateral direction (usually about 45 °), and the projection 13 at the tip of the nose cap 6 is provided. Is applied to the corner portion 12 of the floor material 10 to perform the driving operation. At this time, as shown in FIG. 2, the protrusion 13 at the tip of the nose cap 6 is about 0.5 to 2.0 toward the end of the floor member 10 in the direction perpendicular to the axis 17 of the injection port.
If the stopper 8 is provided with a shift of mm (dimension n), the stopper 8 is displaced by that amount and is driven into the floor material 10.
Even if is tilted, it can be prevented from being driven into the upper surface of the floor material 10. That is, according to the present invention, the tip of the stopper 8 is driven into the convex portion 11 side of the floor material 10, and the probability of being driven into the upper surface of the floor material 10 is reduced.

[0008]

According to the present invention, the nose cap for guiding the tip of the injection port to the corner of the convex portion of the floor member is attached to the tip of the push lever, and the convex portion of the tip of the nose cap is ejected. Since the stopper is provided so as to be shifted in the direction perpendicular to the axis line toward the end portion of the floor member, the probability that the stopper is driven into the upper surface of the floor member is reduced, and the finish in the floor member stopping work can be improved.
