Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tilting mechanism of a nailing machine for fixing the inclination of a nailing machine so that the direction of a nail driven from the nailing machine is always constant.

[0002]

2. Description of the Related Art In general, a floor material is formed by forming a tenon-shaped convex portion on one of the joining end surfaces with an adjacent floor material and a concave groove on the other, and joining them together by joining. Then, when the floor material is nailed and fixed on the base material, as shown in FIG. 6, the nail 13 is obliquely driven into the protrusion 20 at the end of one floor material 14b, and the protrusion 20 should be joined. The other floor member 14b is fitted and fixed in the concave groove 32. Thus, in order to drive the nail 13 obliquely, the nailer body 1 must be inclined obliquely. It is considered that this inclination angle is most preferably about 45 °.

[0003]

However, the body of the nailing machine itself is heavy, so that the arm gradually gets tired while being nailed to a large number of floor members. When fatigue accumulates, it becomes difficult to hold the nailing machine main body at a predetermined inclination, and the inclination of the nailing machine tends to decrease. If the inclination of the nailing machine is small, the nail will be driven out while lying down, and the tip of the nail will not reach the base material or will be very shallow even if it reaches, causing the problem of insufficient fixing. there were.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to provide a nailing machine tilt holding mechanism which can always hold a nailing machine at the same tilt regardless of fatigue of an operator.

[0005]

In order to solve the above-mentioned problems, an inclination holding mechanism for a nailing machine according to the present invention comprises: The tip of the guide at the time of projection is engaged with the surface of the material to be driven, and the tip of the nose portion for nail injection provided on the nailing machine body is attached to the material to be driven. The inclination of the nailing machine is fixed by engaging.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 denotes a nailing machine main body. The nailing machine main body 1 comprises a body 2 having a grip 3 and a nose portion 4 connected thereto, and further having a nose portion 4 provided with a magazine 5 connected thereto. And the main valve 8 is opened and actuated in conjunction therewith to supply the compressed air in the main chamber 9 to the striking cylinder 10 to drive the striking piston 11 and the driver 12 downward, so that the magazine 5
(Including staples) supplied to the nose part 4 from
3 is hit to the target material 14 (the base material 14a and the floor material 14b). The tip 15a of the contact arm 15 is arranged at the tip of the nose part 4,
The tip of the contact arm 15 is formed substantially at a right angle when viewed from the side. Therefore, the tip 15a of the contact arm 15 is the tip of the nose part 4 here.

A support shaft 16 is provided at an upper portion of the front end of the magazine 5 of the nailing machine main body 1 so as to protrude to both sides.
A pair of rod-shaped guides 17 are attached to both sides of the rotating member 6 on both sides thereof. The guide 17 is formed with a pin insertion hole 18 (see FIG. 2) at a slightly distal end side from the middle. A pin receiving portion 19 corresponding to the insertion hole 18 is formed in the nose portion 4 so as to protrude forward. When the guide 17 is rotated to a position corresponding to the pin receiving portion 19, the nailing machine main body 1 is tilted obliquely (about 45
(In such a manner as to incline at an angle of 90 °), it is arranged so as to protrude substantially vertically below the nailing machine body 1.

In the above configuration, the guide 17 is provided so as to rotate about the support shaft 16 between a position parallel to the upper edge of the magazine 5 and a position corresponding to the pin receiving portion 19. . When not used, the guide 17 is held at a position parallel to the upper edge of the magazine 5. In use, the guide 17 is rotated to a position corresponding to the pin receiving portion 19, and the guide 17 is rotated by passing the fixing pin 21 from the insertion hole 18 of the guide 17 to the pin receiving portion 19 as shown in FIG. Secure so that it does not move. In this state, the tip of the guide 17 is driven into the base material 14a of the target material.
When the tip 15a of the nose portion 4 for nail injection provided on the nailing machine main body 1 is engaged with the inner angle of the projection 20 of the floor member 14b to be driven, the nose portion The angle of 4 is automatically determined to an optimum of about 45 °. Further, the nailing machine main body 1 has a pair of guides 17 and a tip 1 of a nose portion.
The posture is stabilized because it is supported at three points 5a. Therefore, when the nail driver is operated by operating the trigger lever 6, the nail 13 is driven at the above angle. After nailing,
In the same manner as described above, the protrusion 20 of the floor member 14b is fitted into and joined to the groove of another floor member, and the protrusion of the floor member is nailed into the base member 14a in the same manner. Less than,
The nail driving operation may be continued in the same manner. Although the fatigue is increased by continuously performing the above operation, the inclination of the nailing machine can always be maintained at about 45 ° regardless of the fatigue of the operator. Therefore, the floor member 14b can always be reliably fixed.

FIGS. 3 and 4 show another example of the tilt holding mechanism of the nailing machine. A supporting member 26 is fixed to the front surface of the nose portion 4 of the nailing machine main body 1 by bolts 27, Member 2
A guide 17 is attached to 6 via a support shaft 28 so as to be rotatable by a predetermined angle. That is, the support member 26
An engagement portion 29 is formed on the upper part of the
An engagement portion 30 that can be engaged with the engagement portion 29 is also formed at the base of 7. The guide 17 is rotatable from the position indicated by the two-dot chain line in the same figure to the position indicated by the solid line where the engaging portions 29 and 30 are engaged with each other. At the tip of the guide 17, a thick rectangular plate-shaped contact portion 31 is formed.

In the above configuration, the guide 17 is held at the position shown by the two-dot chain line in FIG. 3 when not used. Then, at the time of use, the guide 17 is rotated to a position where the engaging portions 29 and 30 are engaged with each other. In this state, the tip of the guide 17 is engaged with the surface of the base material 14a of the material 14 to be driven, and the tip 15a of the nose portion 4 is engaged with the inner angle of the projection 20 of the floor material 14b of the material 14 to be driven. Let it. At this time, the angle of the nose part 4 is automatically set to the optimum
It is set so as to be determined at 5 °. Also, the nailing machine body 1
Is supported at three points: the contact portion 31 and the nose tip 15a, so that the posture is stable. Therefore, when the nail driving machine is operated, the nail can be driven at the above angle. Also in this case, the inclination of the nailing machine is always about 45 regardless of the fatigue of the worker.
°, the floor member 14b can always be reliably fixed.

FIG. 5 shows still another example of the tilt holding mechanism of the nailing machine. The guide 17 is formed in an elongated plate shape, and is rotatably attached to a support shaft 22 at the rear of the magazine 5. . At the tip of the guide 17, a contact piece 23 made of synthetic resin is integrally fixed so as not to damage the floor member 14b. On the other hand, a support rod 25 is also rotatably attached to a shaft 24 at the lower front end of the magazine 5. Guide 1
7 is always closed and is urged by a spring in a direction to rotate to a folding position shown by a dotted line in FIG. It is preferable that the support rod 25 is set to be stronger than the spring force so that the tip of the support bar 25 engages with the tip of the guide 17 and is stored inside the guide 17 when folded.

In the above configuration, the support rod 25 and the guide 1
7 can be used as an ordinary nailing machine by folding it as shown by the dotted line in FIG.

On the other hand, when driving a nail into the floor member 14b, the guide 17 and the support bar 25 are rotated downward as shown by the solid line in FIG. The tip of the support rod 25 is the guide 1
7, the angle formed by the support bar 25 and the guide 17 becomes substantially a right angle, and the angle is maintained by the strength of the spring. In this state, the contact piece 2 at the tip of the guide 17 is
3 is engaged with the surface of the floor member 14b to be driven, and the tip of the nose portion 4 for nail injection provided on the nailer body 1 is engaged with the inner angle of the projection 20 of the floor member 14b. And the angle of the nose part 4 is automatically optimized to about 4
Determined to be 5 °. Further, since the contact piece 23 at the tip of the fixing portion 17 is formed wide, the posture of the nailing machine main body 1 is stabilized. Therefore, when the nail driver is operated by operating the trigger lever 6, the nail is driven at the above angle. After nailing, the floor members may be joined in the same manner as described above.

Also in this case, the fatigue is increased by continuously performing the above-mentioned work, but the inclination of the nailing machine can always be maintained at about 45 ° regardless of the fatigue of the operator. . Therefore, the floor member 14b can always be reliably fixed.
