Description

[Detailed explanation of the invention] (a) Industrial application field This invention is attached to the door side of the case body of a record rack, cabinet, etc., and is attached to the magnetic surface of the magnetic catch of the case body.
It is a metal plate to be attracted that maintains the closed state of the door, and when it is attached to the door, it is called a stable.
This invention relates to a metal plate to be attracted by a magnetic catch that can be used with an automatic nail gun that drives out nails.

(B) Prior Art FIG. 4 is a sectional view showing a metal plate to be attracted by a conventional magnetic catch.

The conventional metal plate 7 to be attracted is a flat metal plate having a size corresponding to the magnetic surface 21 of the magnetic catch 2, and has a screw hole 71 for driving a countersunk screw in which a screw head is buried in the center of the surface. ing. When attaching to the door 3, position the metal plate 7 to be attracted to the magnetic surface 21 of the magnetic catch 2 on the case body side, and use a screwdriver to insert the countersunk screw 72 so that the screw head is buried in the screw hole 71. is driven in and fixed to door 3.

(c) Problems to be solved by the invention The above-mentioned conventional magnetic catch has a metal plate that is attracted to the same size as the magnetic surface of the magnetic catch, and the surface of the metal plate to be attracted is approximately the same size as the magnetic surface of the magnetic catch. A single screw hole is opened inside, that is, in the plane corresponding to the magnetic force plane. When the metal plate to be attracted is fixed to the door with a single screw, it can be firmly fixed in the screw driving direction, but since it is fixed at one point, there is no effect of preventing rotation of the metal plate to be attracted. Therefore, there is a possibility that the metal plate to be attracted may rotate due to frequent opening and closing operations of the door.
By the way, if two screws are driven into the door in the vertical direction, the rotation of the metal plate to be attracted can be prevented. However, the opening on the driving side of the screw hole is made larger in order to bury the screw head of the countersunk screw. Therefore, if many screw holes are provided on the metal plate to be attracted,
Since the degree of adsorption with the magnetic surface becomes weak, it is not possible to provide many screw holes.

On the other hand, if you use an automatic nailing machine (Tatsuker) that drives out two-legged nails (stable) with a U-shaped cross section, you will have to drive two legs vertically in one drive, and the It is thought that the metal plate can be fixed to the door with high work efficiency and to prevent it from turning. However, the stable has a U-shaped cross section, and the central portion where both legs are connected protrudes outward (in the direction of the magnetic force surface) from the metal plate to be attracted in the driven state, making it difficult to close the door. Even if a mounting part is provided in addition to the surface to be attracted, and a recess into which the tip of the tassel is fitted is provided in the mounting part, the depth of the recess will be shallow because the mounting part itself is thin. . Therefore, when the tip of the tacker is fitted into the recess when driving the stable, there is a risk that the tip of the tacker may be displaced in the vertical and horizontal directions. If the tassel is even slightly misaligned, there may be disadvantages such as the inability to drive the stable accurately. For these reasons, conventionally it has not been possible to use a tacker with good workability to attach the metal plate to be attracted to the door.

This invention solves the above-mentioned problems, and provides a metal plate for a magnetic catch that can be fixed to the door without turning with simple work using a tatcher, and that can be installed accurately. The purpose is to

(d) Means and operation for solving the problem In order to achieve this object, the metal plate for attracting the magnetic catch of this invention has the following structure.

The metal plate for the magnetic catch to be attracted is attached to the door side of the case body, and by attracting to the magnetic surface of the magnetic catch on the case body side, the metal plate for attracting the magnetic catch keeps the door closed. The metal plate to be attracted is provided with an attachment part to the door by protruding one end thereof, and an automatic nailer that drives a two-legged nail with a U-shaped cross section into this attachment part. It is characterized by having a fitting part into which the tip of the nail is fitted and which attracts and maintains the fitted state by magnetic force, and a nail hole corresponding to the nail foot of the two-legged nail is provided in the fitting part. .

The metal plate for attracting a magnetic catch having such a structure includes an attracting part corresponding to the magnetic force surface of the magnetic catch, and a mounting part extending integrally from the attracting part. This mounting portion is magnetized and set to be magnetic, and the fitting portion within the surface of the mounting portion is also magnetized. When attaching a metal plate to be attracted to a door, the part of the metal plate to be attracted is placed on the door in a state corresponding to the magnet surface of the magnetic catch. In this state, the attachment part does not correspond to the magnet surface. Here, the tip of the tacker (metal tip) is fitted into the fitting part of the attachment part. At this time, the tip of the tacker is fitted into the fitting part, and the fitted state is temporarily fixed (adsorbed and maintained) by the magnetic force of the fitting part. Therefore, the tip of the tacker does not move vertically or horizontally within the fitting portion, and is maintained in a proper positioning state. In other words, the two legs of the stable that are ejected from the tatker correspond exactly to the two nail holes. Furthermore, the center portion of the stable (made of metal) that is hammered out and passes through the nail hole of the fitting portion is attracted to the bottom surface of the fitting portion, thereby further firmly fixing the metal plate to be attracted to the door. Therefore, in one driving operation, the metal plate to be attracted is fixed by the two upper and lower nail legs by the stable (two-legged nail), and rotation of the metal plate to be attracted is prevented.

(E) Embodiment FIG. 3 is a cross-sectional view showing a state in which a metal plate for being attracted by a magnetic catch according to this invention is attached to a door of the case body 4. Adsorbed metal plate 1
is attached to the door 3 of a case body 4, such as a record rack, in correspondence with the magnetic catch 2 attached to the open end of the case body 4.

The feature of this invention is that when attaching the metal plate 1 to be attracted to the door 3, an automatic nailer (tatsuker) is used to drive out two-legged nails (stable) 6 with a U-shaped cross section.
5 has a structure that can be used.

As shown in FIG. 2, the attracted metal plate 1 is a flat metal plate, and is set to a size corresponding to the magnetic surface 21 of the magnetic catch 2 (attracted part 11). A mounting portion 12 is integrally formed by extending one end of the suction portion 11 to protrude.

The attachment part 12 is a flat plate made of magnetized metal that has been subjected to magnetization treatment, for example, a metal plate for being attracted (attracted part 1
1) It is integrally connected to 1 by butt welding or the like. In addition, a shallow concave fitting part 14 into which the tip part (made of metal) of the tassel is fitted is provided in the plane of the mounting part 12, and this fitting part 14
Stable 6 of 2 hit by Tatsuker inside
Nail holes 15, 15 corresponding to the main legs are opened.
Therefore, when the tacker tip 5 is fitted into the fitting part 14, the fitted state is attracted and maintained by the magnetic force of the fitting part 14.

In order to attach the attracted metal plate 1 of the magnetic catch having such a configuration to the door 3, the attracted part 11 is positioned on the door 3 in a state corresponding to the magnetic surface 21 of the magnetic catch 2. . In this state, the mounting portion 12 does not correspond to the magnet surface 21. Here, as shown in FIG. 2, the tip portion (metal tip portion) 5 of the tacker is fitted into the fitting portion 14 of the attachment portion 12. At this time, the tip 5 of the tacker is fitted into the fitting part 14, and the fitted state is held by attraction (adsorption and retention) by the magnetic force of the fitting part 14. Therefore, the tacker tip 5 does not move vertically or horizontally within the fitting portion 14, and is maintained in a proper positioning state. In other words, the two legs of the stable 6 that are driven out from the tacker 5 correspond exactly to the two nail holes 15. Moreover, the nail hole 1 of the fitting part 14 is hammered out.
The center portion of the stable (made of metal) 6 that penetrates through the opening 5 is attracted to the bottom surface of the fitting part 14, and the metal plate 1 to be attracted is further firmly fixed to the door 3 (see FIG. 3). Therefore, in one driving operation, the metal plate 1 to be attracted is fixed by the two nail legs (upper and lower) by the stable (two-legged nail) 6, so that the metal plate 1 to be attracted is
There is no risk that it will rotate. Moreover, since the tip portion 5 of the tacker is accurately temporarily secured when fitted into the fitting portion 14, accurate nailing can be achieved.

(f) Effects of the invention As described above, in this invention, one end of the metal plate to be attracted is extended and protruded to provide a mounting part for the door, and this mounting part has two legs with a U-shaped cross section. It is provided with a fitting part into which the tip of an automatic nail gun for driving nails is fitted and which attracts and maintains the fitted state by magnetic force, and a nail hole corresponding to the nail foot of the two-legged nail is formed in this fitting part. Because of this, when attaching the metal plate to be attracted to the door, a tatker (automatic nailer) can be used, which improves work efficiency. Moreover, since the stable driven out from the tatker has two legs, the metal plate to be attracted can be secured to the door at two points and prevented from rotating in one driving operation. In addition, since the fitting part of the mounting part is magnetized, it can not only attract and hold the tip of the tassel in the proper position, but also attract and hold the driven stable, making it even more firmly fixed to the door. etc., it has excellent effects that achieve the purpose of the invention.
