Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magazine for a nail gun in which a large number of nails are connected in parallel by a connecting member such as iron wire, and connected nails are loaded in a coiled manner.

Conventionally, the following configuration is known as a magazine for loading this type of connecting nail.

In other words, a cylindrical magazine body is formed with an opening that serves as a nail loading port at the upper end, a column is installed in the center of the bottom wall of the magazine body, and the opening is connected to the magazine body through a hinge mechanism. The connecting nail is loaded from the upper side of the magazine main body so that the center part of the connecting nail fits into the support column.

The support column is essential in the magazine in order to prevent the connecting nail from unwinding when the connecting nail is pulled out from the magazine body by the nail feeding mechanism.

One side of the magazine configured as described above is fixed to a nail guide plate constituting a nail feeding device provided on the nose side protruding from the nailer main body, and the other side is fixed to the nail guide plate that constitutes the nail feeder provided on the nose side protruding from the nailer main body. The magazine body is fixed to a mounting portion provided at the distal end of a grip portion protruding from one side of the magazine, and the opening of the magazine body is located substantially below the grip portion.

Therefore, when loading the connecting nail into the magazine main body, the connecting nail is inserted into the limited space formed between the grip part and the magazine main body so that the center part of the connecting nail is inserted into the support column of the magazine main body. The reality is that the nail must be loaded so that it fits into the body, making loading the nail time-consuming.

Therefore, the present invention was proposed in order to solve the above-mentioned conventional drawbacks, and it is possible to connect a large number of nails in parallel using a connecting material, and to easily load the connected nails into a magazine by winding them into a coil. The purpose is to reduce the reloading time.

Another object of the present invention is to reduce the weight of the entire magazine.

The present invention also provides a bottom plate on which a plurality of nails are connected in parallel with a connecting material and is wound in a coil shape on which the connecting nails are placed, and a lower edge is fixed to the bottom plate and a portion of the outer periphery is fixed to the bottom plate. The connecting nail is provided with an annular side plate connected to a nail guide plate constituting the nail feeding device, and a column body inserted into the center of the connecting nail, and the connecting nail is inserted through a nail loading port provided in the side plate. The pillar body is placed on the bottom plate, and the pillar body is configured to be inserted and held in the center of the connecting nail via an elevating means after the connecting nail is placed on the bottom plate. .

A connecting plate 16 connected to a mounting plate 15 extending from the tip 3a side is fixed, and the state of attachment to the nail gun main body 2 is stable.

Further, in the side plate 11, about 2/3 of the area from the attachment part 11c to the midway part 11d of the connection plate 14 is at the upper edge 1.
1b to the lower edge 11a, and an opening 17 that serves as a nail loading port for the connecting nail 100 is formed.

On the other hand, the column 18 inserted into the center part 101 of the connecting nail 100 has a column operation plate 1 bent at approximately 90 degrees.
It is fixed to the lower surface 20a of the bent portion 20 of No. 9 so as to hang down.

The column body 18 has a tapered shape whose diameter gradually decreases from the middle part 18a to the tip 18b so that it can be easily inserted into the center part 101 of the connecting nail 100.The connecting nail 100 is attached to the base end 18c.
An annular groove 21 is formed so that the head of each nail on the inner peripheral side of the connecting nail 100 is turned inward when the connecting nail 100 is loaded.

One end 19a side of the columnar operation plate 19 has an inclined surface 2.
2 and is bent into a U-shape to form a joint portion 23.

The upper end 24a side of a shaft body 24, which is located on the outer circumference 11A side of the side plate 11 of the magazine body 9 and is arranged to stand up between the bottom plate 10 and the top plate 12, is inserted into the end portion 23a of the joint portion 23. A through-hole 25 is provided for the purpose of the present invention.

The upper end 24b side of the shaft body 24 is inserted into a through hole 26 formed in the bottom plate 10, and the upper end 24a side is inserted into the top plate 12 through the through hole 25 of the end 23a of the joint portion 23.

Further, a conical joint receiving portion 28 is provided on the upper end 24a side of the shaft body 24, and the end portion 23 of the joint portion 23 is provided with a conical joint receiving portion 28.
The lower surface 29 of a is received by the annular inclined surface 30 of the joint receiving portion 28.

Further, the shaft body 24 has a compression coil spring 32 which is fitted on the outer circumference of the shaft body 24 and whose both ends 32 a t 32 b are supported between the lower surface 31 of the joint receiving portion 28 and the top of the bottom plate 10 . It is always elastically biased upward.

On the other hand, on the lower surface 33 on the other end 19b side of the column operation plate 19, an L is provided which engages with the head of the outermost nail of the connected nail 100 so that the connected nail 100 loaded therein does not unravel outward. A letter-shaped presser plate 34 is fixed in a hanging manner.

Next, the process of loading the connecting nails 100 into the magazine 8 having the above structure will be explained.

First, lift the other end 19b side of the column operation plate 19 upward to bring the column 18 out through the insertion hole 13 of the top plate 12 of the magazine body 9, and position the column 18 on the outside of the magazine body 9. The operation plate 19 is rotated in the direction of arrow A in FIG. 3 using the joint portion 23 as a fulcrum until it is turned.

When the column 18 is located outside the magazine body 9, the lift-up state of the other end 19b of the column operation plate 19 is released.

Then, the operation plate 19 returns to its pre-operation state due to the biasing force of the compression coil spring 32 provided in the joint 23, that is, the state in which the operation plate 19 is parallel to the top plate 12 of the magazine body 9. .

After the column 18 is taken out from the magazine body 9 in this way, the connecting nail 100 is placed on the bottom plate 10 through the opening 17 formed in the side plate 11 of the magazine body 9.

Then, the column operation plate 19 is operated to return, and the column 1 is
8 is the center portion 10 of the connecting nail 100 placed on the bottom plate 10 through the insertion hole 13 of the top plate 12 of the magazine body 9.
Insert into 1.

As described above, according to the magazine 8 having the above configuration, even if one hand is holding the grip part 3 of the nail gun main body 2, the connecting nail 100 can be inserted into the magazine from the lateral direction of the magazine 8 with the other hand. Since the connecting nail 1'00 can be loaded into the main body 9, loading of the connecting nail 1'00 is easy even when the nail runs out in the middle of the nail driving operation, and time can be shortened.

Further, since the column 18 is inserted into the center part 101 of the loaded connecting nail 100, it is possible to prevent the connecting nail 100 from unraveling inwardly. 34 can also prevent the connecting nails 100 from unraveling outward, so that a stable loading state of the connecting nails 100 loaded into the magazine body 9 can be ensured.

Further, by removing about two-thirds of the side plate 11 of the magazine body 9, the weight of the entire magazine 8 can be reduced.

As described above, according to the present invention, a large number of nails are connected in parallel using a connecting material, and the time required to load a connected nail into a magazine in a coiled manner is shortened. Even if a nail runs out, a connecting nail can be loaded immediately.

Therefore, operator fatigue is reduced compared to the conventional method.

In addition, since it is easy to load the connecting nails, it is very effective at work sites with poor footing.

In addition, the overall weight of the magazine can be reduced, so
This reduces the overall weight of the nailer, making nail driving easier.
