Description

[Detailed description of the invention] This invention relates to the improvement of fittings for hinged doors such as entrance doors and gates.

The above hinged door fittings have one side held by a hinge or a pivot so that they can be opened and closed, and therefore have the disadvantage that they are easily deformed by their own weight acting on the other side. In conventional fittings, the above deformation was prevented by elaborately machining handles and handle holes at the joints of the stile, and by holding and reinforcing the end plate within the frame made of the stile. However, a long-term deformation prevention effect cannot be obtained.
Further, the above-mentioned pattern processing requires a skilled technique, and there is a drawback that the entire surface of the hinged door is blocked by the mirror plate.

This invention was made to eliminate the above-mentioned drawbacks, and it is possible to reliably prevent the fittings from deforming with a simple structure, and it can be easily processed and assembled without requiring any skill. To provide a fitting for a hinged door which can open the part surrounded by the frame of the hinged door as appropriate without necessarily providing a mirror plate in the frame.

That is, this invention consists of an outer frame consisting of left and right vertical frames and upper and lower horizontal frames, an inner frame consisting of upper, lower, left and right side members, and a reinforcing frame made by integrally molding upper, lower, left and right metal plates into a picture frame shape. A slit into which the outer periphery of the reinforcing frame is fitted is formed on the inner peripheral surface of the outer frame, and a slit into which the inner periphery of the reinforcing frame is fitted into the outer periphery of the inner frame. That's what happens.

Embodiments of this invention will be described below with reference to the drawings. Figure 1 shows the disassembled state of the fittings according to this invention.
An outer frame 1 consisting of 2 and 13, a reinforcing frame 2 held inside this outer frame 1, and left and right side members 30 and 3.
1 and an inner frame 3 consisting of upper and lower side members 32 and 33. The reinforcing frame 2 is formed integrally into a picture frame shape by firmly joining upper, lower, left and right reinforcing plates made of strong metal plates such as stainless steel or aluminum by means such as welding, or by punching a flat metal plate. There is. Furthermore, a slit 14 into which the outer peripheral portion of the reinforcing frame 2 is fitted is formed in the inner surface of each of the frames 10 to 13 constituting the outer frame 1, and each of the side members 30 to 13 constituting the inner frame 3 is formed.
A slit 34 is formed on the outer surface of the reinforcing frame 2 into which the inner peripheral portion of the reinforcing frame 2 is fitted. This slit 1
4 and 34 can be easily and uniformly formed using a circular saw or the like.

In the above configuration, after assembling the inner frame 3 by fitting and press-fitting the slits 34 of each of the side members 30 to 33 into the inner periphery of the reinforcing frame 2 (see FIG. 1), the reinforcing frame 10~ each frame on the outer periphery of 2
The outer frame 1 is assembled by fitting the slits 14 of 13 onto the outside and press-fitting them. and Figures 2 and 3.
As shown in the figure, fittings 20 are formed by fitting the lattice material 4 into the inner frame 3 and fixing it by means of press-fitting, nailing, gluing, or the like. Further, the outer frame 1 and the inner frame 3 are press-fitted into the reinforcing frame 2 to be integrated. In addition, outer frame 1
The outer frame 1 may be integrated by connecting the corner portions of each with L-shaped metal fittings, or by fixing the outer frame 1 and the reinforcing frame 2 by adhesives, screws, or other means. Further, as shown in FIG. 4, a recess 15 into which the outer peripheral part of the inner frame 3 is fitted is formed on the inner surface of the outer frame 1, and by fitting them together, the outer frame 1 and the inner frame 3 can be connected. They may be integrated, and in this case there is an advantage that the reinforcing frame 2 can be completely hidden by the outer frame 1 and the inner frame 3.

Since the outer frame 1 and the inner frame 3 of this fitting 20 are reinforced by the reinforcing frame 2 which is integrally formed into a picture frame shape in advance, deformation can be reliably prevented.
That is, when one vertical stile 10 of the outer frame 1 is held by a hinge or a pivot and used as a hinged door, the other vertical stile 11 will sag under its own weight, and the upper and lower horizontal stile 12, 13 will be loaded in the direction of inclination. However, since this load can be received by the reinforcing frame 2, deformation of the outer frame 1 and the inner frame 3 can be reliably prevented.

In addition, the outer frame 1 and inner frame 3 can be easily assembled by simply fitting each component onto the reinforcing frame 2, and sufficient shape retention can be obtained without the need for elaborate pattern processing. , no skill is required for processing and assembly, and manufacturing costs can be kept low. In addition, in order to improve the appearance of the outer frame 1, handles and handle holes may be processed at the joints of the frames 10 to 13, and the joints may be connected to each other.

Further, it is not necessary to provide a shape-retaining end plate inside the inner frame 3, and the vertical bar 40 is not necessarily provided inside the inner frame 3.
By arranging the lattice material 4 consisting of the horizontal beams 41, the inside of the fitting 20 can be opened. Therefore, there is an advantage that it can exhibit an excellent appearance and that the weight of the entire fitting can be reduced. Note that various modifications are possible, such as arranging a louver and a glass plate inside the inner frame 3 instead of the lattice material 4 described above. For example, when arranging a glass plate, a recess 50 is formed in the inner periphery of one side of the inner frame 3 as shown in FIG.
By fitting the outer periphery of the glass plate 5 inside, placing the push plate 51 on top of it and fixing it with screws 52,
The outer periphery of the glass plate 5 may be held.

As explained above, this invention has a simple structure with sufficient shape retention, can be easily processed and assembled without requiring any skill, and can reliably prevent deformation of fittings. Furthermore, by opening the inside of the fitting, it has the advantage of providing an excellent appearance and reducing the weight of the fitting as a whole.
