Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a magazine for storing a nail band in which nail groups are arranged in parallel in a wound state in a nail gun.

(Prior art) Conventional nailing machines use two types of nails: one is a chevron-shaped nail group in which the nail rows are wound so that the nail heads are arranged in a substantially chevron-like shape, and the other is a chevron-shaped nail group in which the nail rows are arranged in a flat shape. A flat type nail group with a row of nails wound around it was used, each of which was stored in its own magazine.

(Problem to be solved by the invention) Therefore, two types of magazines are required, each having a shape that is adapted to the winding form of both nail groups.
There was a problem that the management effort was complicated.

In view of the above problems, an object of the present invention is to provide a magazine for a nail gun that can be used commonly for the two types of nail groups.

(Means for Solving the Problems) The present invention has a magazine cap attached to the magazine case attached to the main body of the nailer in order to cover the magazine case so that it can be opened and closed. When storing a group of chevron-shaped nails in which rows of nails are wound so as to be arranged in a pattern, an inclined portion formed to be parallel to and opposite to a group of nail heads of this group of chevron-shaped nails, and a nail head. When storing a flat type nail group in which the nail rows are wound so that the groups are arranged in a substantially flat shape, the nails are arranged parallel to each other near the outer layer of the nail head group of the flat type nail group. The gist of the magazine is a magazine with a flat section connected inside and outside.

(Function) The magazine of the present invention has a flat part that covers the outer layer of the flat type nail group in the magazine cap, and an inclined part that covers the inner side of the outer layer of the chevron type nail group, respectively. The magazine is formed parallel to the shape and is configured so that the magazine can be used in common for a group of flat type nails and a group of chevron type nails.

(Embodiment) Next, an embodiment of the present invention will be described with reference to the drawings. In the figure, 1 is the main body of the nailer, 2 is a driver guide extending below the main body 1, and 3 is a driver. This is a magazine case for a magazine M installed to store a group of nails to be fed to the guide 2, and includes a protrusion 4a at the rear end of the handle 4 extending rearward of the main body 1, and a protrusion 4a at the rear end of the driver guide 2. mounted in an inclined manner with respect to the continuous guide rail 5, and
It is formed into a substantially bottomed semi-cylindrical shape with an open top and one side, and a storage chamber 6 for storing a group of nails is formed inside, and a wound state is formed in the center of the bottom surface 3a. A support shaft 7 for fitting and supporting the nail band is provided protrudingly, and a movable shaft 7a is elastically inserted into the support shaft 7.

A magazine cap 8 is installed opposite to the magazine case 3 to cover the sides of the guide rail 5 and the storage chamber 6 in an openable and closable manner, and is screwed onto the driver guide 2 and attached to the protrusion 4a of the handle 4. A substantially semi-cylindrical side wall portion 8a is provided at the rear of the storage chamber 6 to cover the open side surface of the storage chamber 6.
A lid portion 8b having a circular planar shape is connected to the upper end of the side wall portion 8a to cover the upper side of the storage chamber 6. Near the outer periphery of the lid part 8b, there is a group of nail heads K in a nail strip in which nails K to K are connected in parallel via wires, tapes, etc.
When the flat type nail group T1, in which the nail rows are wound so that the nails 1 to K1 are arranged in a flat shape with the nail head height L1 as a whole, is stored in the storage chamber 6 (see Fig. 1A). , in order to cover the vicinity of the outer layer of the flat type nail group T1 in close proximity to the nail head group K near the outer layer, it is placed parallel to the nail head group K near the outer layer and parallel to the bottom surface 3a of the magazine case 3. A flat portion 9 is formed in a substantially C-shaped plane over approximately half the circumferential surface of the lid portion 8b on the driver guide 2 side, and inside the flat portion 9, the height of the nail heads of the outermost layer nail row is formed. L
2 (where L2<L1), the nail head height gradually increases toward the inner layer, and near the outer layer of the chevron-shaped nail group T2, where the nail row is wound so that the nail head group K1 is arranged in an almost chevron-shape. In order to cover the inside of the nail head group K1 in close proximity to the nail head group K1, a sloped portion 10 is disposed parallel to the nail head group K1 and has a conical lower surface.

Reference numeral 11 denotes a leaf spring-like spring fixed to the inner surface near the center of the side wall 8a of the magazine cap 8 via a pin 12, and a base piece 11a attached perpendicularly to the inner surface of the side wall 8a. At the upper end, a magazine cap 8 is provided to press against the nail head group K1 of the chevron nail group T2 when the chevron nail group T2 is stored in the storage chamber 6, and to restrict the upward movement of the chevron nail group T2. The upper resilient contact piece 1 extends inwardly along the inclined portion 10 of the
1b is bent and formed, while the lower end of the base piece 11a is pressed against the circumferential body surface of both nail groups T1, T2 when the winding diameter of both nail groups T1, T2 stored therein is large. , a lower elastic contact piece 11 extending laterally along the inner peripheral surface of the side wall portion 8a in order to restrict the movement of the outer layer of T2.
c is integrally formed.

Next, the operation and effects of the embodiment having the above configuration will be explained.

Now, in this example, the nail head group K1 is approximately in the top on the lid part 8b of the magazine cap 8, which is installed opposite to the magazine case 3 in order to cover the magazine case 3 attached to the main body 1 of the nailer so that it can be opened and closed. When the chevron-shaped nail group T2, in which nail rows are wound so as to be arranged in a pattern, is stored in the storage chamber 6, the nail head group K of the chevron-shaped nail group T2
1, and a flat type nail group T1 in which the nail rows are wound so that the nail head groups K1 are arranged randomly, are stored in the storage chamber 6. A flat part 9 is formed so as to be parallel to the outer layer of the nail head group K1 of the flat type nail group T1 when the flat type nail group T1 is pressed.

For this reason, a flat type nail group T with a constant nail head height
1 is covered and stored in a flat part 9 so that the upward movement of the nail group T1 is regulated, and a chevron-shaped nail group T2 whose nail head height gradually increases is regulated in its upward movement by a slope part 10. Both nail groups T1 and T2 can be stored with the lids covered as shown in FIG.
1 and T2, which has the effect of eliminating the disadvantages of using two types of magazines together.

Further, in this example, when the winding diameter is large, the lower elastic contact piece 11c of the spring 11 is pressed against the circumferential body surface of the flat nail group T1 and the chevron nail group T2 stored in the storage chamber 6, respectively, And angle-shaped nail group T2
The upper elastic contact piece 11b of the spring 11 is attached to the nail head group K1.
Since the structure is such that both nail groups T
1. To accurately prevent rattling during use of T2, the lower elastic contact piece 11c is used to protect the vicinity of the outer layer of both nail groups T1 and T2, where the arrangement of nails K tends to fluctuate especially when the winding diameter is large. This has the effect of stabilizing the arrangement posture of the nail rows near the outer layer and preventing troubles during use due to rattling of both nail groups T1 and T2.

(Effect of the invention) In other words, the present invention has a magazine cap attached to the magazine case attached to the nailer body in order to cover the magazine case so that it can be opened and closed.
A row of nails is wound so that the nail heads are arranged in a substantially chevron shape.When storing a chevron-shaped nail group, the nail row is formed so as to be placed parallel to the nail head group of the chevron-shaped nail group. When storing a flat type nail group in which a row of nails is wound so that the slope part and the nail heads are arranged in a substantially flat shape, the flat type nail group is placed parallel to the vicinity of the outer layer of the nail head group of the flat type nail group. By arranging the flat part shaped like this inside and outside in a row, flat nail groups and chevron nail groups with different winding forms can be stored stably, and both nails can be stored in a common magazine. It has the effect of allowing the groups to be used together.
