Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a hinge attaching device for a metal door, which is formed by joining door panels on both inner and outer sides through a reinforcing member having a U-shaped cross section.

[Conventional technology]

As shown in Japanese Utility Model Publication No. 58-34224 and Japanese Utility Model Publication No. 61-8283, both ends of the inner and outer door panels are hook-shaped with end plates and folding plates, and the inner and outer door panels are provided with a reinforcing material. There is known a metal door which is joined to the back plate of the reinforcing member by being abutted on the back plate of the reinforcing member.

[Problems to be solved by the device]

To attach a hinge to such a metal door, simply attach the hinge to the end plates of the inner and outer door panels and screw the screws from the hinge to the back plate of the reinforcing material to make the hinge easier. Can be attached to.

However, when the hinge is attached in this way, the folded plate and the end plate may be deformed by tightening the screws strongly, and the attachment strength of the hinge cannot be increased.

In order to solve this, it can be considered to interpose a reinforcing liner between the end plate and the back plate of the reinforcing material so that the folding plate and the end plate are not deformed even when the screws are strongly tightened.

However, in this case, a reinforcing liner must be provided between each of the inner and outer door panel end plates and the folding plates, which not only increases the number of reinforcing liners, but also increases the number of reinforcing liners to a predetermined value until the screw is tightened. It has to be temporarily held in a position, and its operation becomes very troublesome, which makes the hinge installation troublesome.

Therefore, an object of the present invention is to provide a hinge attaching device for a metal door which can easily attach the hinge and can increase the attaching strength of the hinge.

[Means and Actions for Solving the Problems]

A reinforcing liner is interposed between the end plate of the door panel and the reinforcing material, and the hinge that abuts the outer surface of the end plate penetrates the reinforcing liner and is tightened with a screw screwed to the back plate provided on the inner surface of the reinforcing material. In addition to forming a notch that the reinforcing liner faces on the folded back plate of the door panel, attach the back plate with the protruding piece to the reinforcing material and reinforce the through hole that fits and snaps with the protruding piece It is a hinge attachment device formed on the liner, which prevents deformation of the end plate and folded plate even if screws are tightened strongly, and can increase the attachment strength of the hinge. Since the reinforcing liner can be temporarily held at a predetermined position of the reinforcing member by fitting the through hole to the protruding piece of the back plate, the hinge can be easily mounted.

〔Example〕

As shown in FIG. 1, both ends of the inner and outer door panels 1 are bent in a hook shape and provided with an end face plate 2 and a folding plate 3, and a reinforcing member 4 is a cross section of a back plate 5 and both side plates 6 and 6. The door panels 1 on the inner and outer surfaces are joined to each other through the reinforcing member 4, and the end faces of the folding plates 3 are in contact with the rear plate 5 of the reinforcing member 4.

The hinge 7 is brought into contact with the outer surface of each of the end plates 2 and 2, and a reinforcing liner 8 is arranged between the inner surface of the end plate 2 and the outer surface of the back plate 5 of the reinforcing member 4 to form the back plate 5. The back plate 9 is provided on the inner surface of the
Screw 7 is attached to back plate 9 from hinge 7 to attach hinge 7.

Next, the hinge attachment portion will be described in detail.

As shown in FIG. 2, a cutout portion 11 is formed in the hinge attachment portion of the folding plate 3, and a cutout recess portion 12 and a pair of screw insertion holes 13 and 13 are formed in the end face plate 2 to enhance the reinforcement. As shown in FIGS. 2, 3, and 4, the liner 8 is a rectangular resin plate having a predetermined width, length, and thickness, and its width a and length b are the inner and outer door panels 1,1. The cutout recesses 11, 11 formed in the above are fitted to each other, and the thickness c contacts the outer surface of the back plate 5 of the reinforcing member 4 and the inner surface of the end face plate 2 of the door panel 1, and the reinforcing liner. A through hole 14 is formed in the central portion of 8, and the through hole 14 is a square hole, and wedge-shaped projection pieces 15 and 15 are formed on the inner surfaces facing each other, and screws are provided on both sides in the longitudinal direction. Insertion holes 16 are formed so as to face the screw insertion holes 13 formed in the end plates 2 and 2 of the pair of door panels 1 and 1, respectively, and a through hole 14 is further formed. Both sides in the width direction toward the space portion 17, 17 in order to facilitate elastic deformation is formed, respectively.

As shown in FIGS. 2 and 4, the back plate 9 has a rectangular plate-shaped body having a narrow central portion in the longitudinal direction and is bent in a U shape to have a protruding piece 18. The piece 18 is fitted into the through hole 19 formed in the back plate 5 of the reinforcing member 4,
Screw holes 20 are formed in the protruding piece 18 and the wide portions on both sides.

Because of this, the projection piece 18 of the back plate 9 is fitted into the through hole 19 of the reinforcing member 4 and temporarily held, and the through hole 14 of the reinforcing liner 8 is fitted into the projection piece 18 to form a wedge shape. The projection piece 15 is temporarily fixed by engaging with the projection piece 18, and in that state, the door panels 1, 1 on both the inner and outer surfaces are joined via the reinforcing member 4.

Then, the hinge 7 is brought into contact with each of the end plates 2 and 2 so that the screws 10
Is screwed into the screw hole 20 of the back plate 9 and the hinge 7 is attached.

5 and 6 show a second embodiment, in which the length b of the reinforcing liner 8 is made longer than the notch 11 and the slit grooves 21 into which the folding plates 3 are fitted are formed on both sides in the longitudinal direction,
The slit groove 21 is fitted to the portion of the folding plate 3 near the notch 11 so that the folding lines 3, 3 of the pair of door panels 1, 1 are sandwiched by the reinforcing liner 8.

In this way, the reinforcing liner 8 can prevent the door panels 1, 1 on both the inner and outer surfaces from expanding and deforming.

As shown in FIGS. 7 and 8, a pair of locking protrusions 22, 22 are integrally formed on the back surface of the reinforcing liner 8, and holes 23, 24 are formed in the back plate 5 and the back plate 9 of the reinforcing member 4. The locking projection 22 into the holes 23, 24.
The reinforcing liner 8 can be attached by fitting it to.

By doing so, the reinforcing liner 8 is attached to the portion where the hinge is not attached as shown in FIG.
It is possible to prevent the expansion deformation of 1,1.

[Effect of device]

Since the reinforcing liner 8 is interposed between the end face plate 2 and the reinforcing member 4, the end face plate 2 and the folding plate 3 are not deformed even if the screw 10 is strongly tightened, and the attaching strength of the hinge 7 can be strengthened. .

Since the notches 11 are formed in the folding plates 3 and 3 of the door panels 1 and 1 on both the inner and outer surfaces, the reinforcing liner 8 is formed from the notches 11 to the end plates 2 and 2 of the door panels 1 and 1 on both the inner and outer surfaces and the reinforcing member 5. Since the reinforcing liners 8 can be arranged over the space, the number of the reinforcing liners 8 can be reduced, and the projection pieces 18 of the back plate 9 provided on the inner surface of the reinforcing material 5 project to the outer surface from the through holes 19 of the reinforcing material 5 to form the reinforcing liner 8. Is formed with a through hole 14 for snap-fitting and locking to the projection piece 18, so that by fitting the through hole 14 of the reinforcing liner 8 to the projection piece 18 by snap-fitting, the outer surface of the reinforcing member 5 is The reinforcement liner 8 does not have to be temporarily held at the time of tightening the screws, and together, the work of attaching the hinge can be facilitated.
