DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magazine for a nailing machine having a structure in which a grip does not interfere with the loading of nails.

[0002]

2. Description of the Related Art Generally, a nailing machine is, as shown in FIG.
The compressed air stored inside the grip portion 31 is discharged to the body 3
The nail is supplied instantaneously into a striking cylinder 33 provided inside 2 and drives a driver 35 coupled thereto along with a striking piston 34 to strike and strike a nail 37 supplied to a nose portion 36. Part 31 and nose part 3
A magazine 38 is provided between the nose portion 6 and the nose portion 36 through the guide passage 40.

In the conventional magazine structure, a nail post 41 is erected at the center of the bottom of the magazine 38, and the nail post 41 is located below the grip portion 31, and a gap between the magazine 38 and the grip portion 31 is provided. Loading a new connecting nail into the magazine was cumbersome because

Therefore, in order to facilitate the loading operation, the height of the nail post can be adjusted (for example, Japanese Utility Model Laid-Open Publication No. 6-85769), or the entire magazine can be tilted sideways (for example, the actual Japanese Utility Model Publication No. No. 39884) is known.

[0005]

However, all of the conventional solutions have a problem that the structure is complicated and the cost is high.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a magazine for a nailing machine which solves the above-mentioned problems and has a particularly simple structure and which can facilitate the work of loading a connecting nail.

[0007]

In order to solve the above-mentioned problems, a magazine for a nailing machine according to the present invention is divided into two right and left magazines for supplying a connecting nail to a nose portion for injecting a nail of a nailing machine. A magazine cap is mounted on the magazine main body so that one can be opened and closed with the other as a magazine main body, and the other is inserted into a space formed at the center of the connection nail wound in a coil shape at the bottom of the magazine main body. The nail post and the plate-shaped post support projecting from the base of the nail post are rotatably arranged so as to be tilted outward, and the rotation axis is displaced outward from the center of the nail post.
And the nail post and post support
Are always biased outward .

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a view of a magazine according to the present invention as viewed from the back side of a nailing machine. As shown in FIG. 4 , the magazine is mounted on a nail injection nose portion 36 of the nailing machine. It supplies a connecting nail and is divided into two parts on the left and right.

[0009] While the first magazine in the magazine body, the side walls 3 and top plate 4 and the bottom 5 of substantially half the circumference with integrally formed, the bottom 5 of the semicircular plate is wound on a coil form Nail post 6 to be inserted into the center space of the connecting nail and plate-shaped post support 7 projecting from the base of nail post 6
Are provided.

The nail post 6 and the post support 7 are formed integrally. As shown in FIG. 2, the nail post 6 is formed in a hollow cylindrical shape, is fitted to the outside of the inner cylinder 8, and has a coil spring with respect to a spring receiver 9 arranged at the base of the inner cylinder 8. Attached via 10. A bearing 11 is formed at a position offset from the center P of the base of the inner cylindrical body 8 to the outside, and a rotating shaft 12 provided on the bottom 5 of the magazine body 1 is supported on the bearing 11. ing. The rotating shaft 12 is also deviated outward from the center P of the nail post 6 . As a result, the nail post 6 can be rotated so that the magazine main body 1 is inclined outward about the rotation shaft 12 .

A connecting portion 13 protrudes from an upper portion of the top plate 4 of the magazine body 1, and the connecting portion 13 is attached to a mounting portion 14 which protrudes downward from an end of a grip portion 31 of the nailing machine.
Are connected via The front portion of the magazine body 1 is connected to the nail guide passage 40 as shown in FIG.

[0012] In contrast, the other 2 magazine cap magazine, magazine cap 2 a sidewall of the remaining substantially half 3
And a top plate 4 and a bottom portion 5 are integrally formed, and are rotatably connected to an end of the side wall 3 of the magazine body 1 via a hinge 16.

In the above configuration, when loading the connecting nail, the magazine is opened by rotating the magazine body 1 about the hinge as shown in FIG. Then, the nail post 6 and the post support 7 are rotated 45
Tilt about a degree. As a result, the nail post 6 is disengaged from the grip portion 31 of the nailing machine and is opened in the extension direction thereof. . Since the rotating shaft 12 of the nail post 6 is eccentric, the nail post 6 rotates in the direction of arrow A in FIG. Since the magazine top plate 4 does not move upward during the connection nail loading operation, the hand holding the grip portion 31 may be left as it is. Thereafter, the magazine main body 1 may be rotated so as to close with respect to the magazine cap 2.

[0014] Thus, the magazine is one which can be easily loaded work by a simple structure of simply decentering the pivot shaft 12.

The nail post 6 is provided with an appropriate elastic means 21 such as a spring as shown by a dotted line in FIG. 3 and biased so that the post support 7 is always inclined. Is inclined, so that the loading operation of the connecting nail 19 becomes easier. In this case, even when the connecting nail is not loaded, the edge of the support 5 of the slanted nail post 6 comes into contact with the edge of the bottom 5 of the magazine cap 2, and the post support 7 is closed by closing the magazine cap 2. When the edge of is pushed back to the original position and the magazine cap 2 is completely closed, the post support 7 is in the state shown in FIG.

Further , the magazine cap 2 may be rotatably connected to the bottom 5 of the magazine body 1.
