Conventionally, this type of framework was
The one described in Publication No. 24519 is known. but,
In order to orthogonally connect the first member and the second member,
A large notch was required at the connecting part, and machining thereof was time consuming. On the other hand, in the connection structure generally referred to as the "horse-rest type," it is difficult to position the connection part.

The present invention solves these problems, reduces machining, simplifies manufacturing, and enables reliable positioning of two orthogonally connected members. The purpose is to improve the sense of beauty.

Hereinafter, the present invention will be explained in detail based on drawings showing embodiments.

In FIGS. 1 to 5, 1 is a first member; 2 is a first member;
is a second member, both of which are made of metal extrusion, and furthermore, both members 1 and 2 have support pieces 4 and 4 on the opening edge 3 in the longitudinal direction for holding the panel (described later);
The first member 1 and the second member 2 are orthogonally connected to form a framework for doors, shoji screens, and other fittings.

The first member 1 on the upper side is a cylindrical portion 5 having a substantially square cross section.
A supporting portion 8 having a contact surface 7 having a width equal to the plate thickness dimension T of the side plate portions 6, 6 projects from the parallel side plate portions 6, 6 of the cylindrical portion 5; An inclined edge surface 9 that slopes inward is continuously formed, and the tip of the inclined edge surface 9 is bent inward to form a grip portion 1.
0 is formed. That is, the supporting pieces 4, 4 each have a supporting part 8, an inclined edge surface 9, and a gripping part 10, and have a cross-sectional shape in which the opening edge 3 is gradually narrowed. 10 is parallel to the bottom surface 11 of the cylindrical portion 5.

Further, the lower first member 1 serving as a middle support is similarly formed with a pair of support pieces 4 on the upper and lower sides, with a web 12 in the shape of a single horizontal letter being interposed therebetween. Also,
The second member 2 has the same cross section as the latter first member 1.

Thus, a shallow notch 13 is formed in the middle of the first member 1 in the longitudinal direction. Specifically, only the gripping portion 10 of the support piece 4 of the first member 1 is cut out to form a shallow notch 13, and this shallow notch 1
The width H of the web 12 is set to be the same as or slightly larger than the thickness G of the web 12.

Further, on the end surface A of the second member 2, a notch recess 14 is formed by cutting out the support pieces 4, 4 and the central web 12 in an inverted triangular shape as shown in FIG.
An inclined cutout 15 corresponding to the inclined edge surface 9 of the support piece 4 of the member 1 is formed. Then, the web 12 remains in the center with both sides open, and the end surface A
stand out.

Next, as shown by arrow B, the protrusion of the web 12 at the end of the second member 2 is cut into the shallow notch 13 of the first member 1.
By fitting the notches 15, 15 into contact with the inclined edge surfaces 9, 9, respectively, misalignment in the direction of arrow X in FIG. 1 and misalignment in the direction of arrow Y in FIG. 2 can be reliably prevented. and positioned. In addition, the ends 16 of the support portions 8 on the front and back surfaces of the second member 2 are in contact with the contact surfaces 7, 7 of the first member 1, so that the outermost surfaces of both the front and back surfaces of the first member 1 and the second member 2 are the same. It becomes flat.

In addition, in FIG. 3, the end face of the second member 2 is shaped like Mt. Fuji, but the second member 2, which has the same cross section as the lower first member 1 in FIG. This is because if the holes 14 and 14 are notched, they will be formed by themselves.

Next, FIGS. 6, 7, and 8 show another embodiment in which only the gripping parts 10, 10 are made to protrude in the longitudinal direction by a predetermined length in the notch 15 of the second member 2. Protrusions 17, 17 are formed, and correspondingly, the width H of the shallow notches 13, 13 of the first member 1 is made the same as the width F of the second member 2. When the second member 2 is fitted into the first member 1 as shown by arrow B, the protrusions 17, 17 are fitted into the shallow notches 13, and come into contact with the ends of the shallow notches 13, 13. It can be positioned without sagging.

Another embodiment shown in FIG.
0 is formed into an L-shape in cross section, and shallow notches 13, 13 are provided in the inner protruding portion of this L-shape. In this case as well, assembly is possible as shown in FIG.

Another embodiment shown in FIG. 10 differs from the embodiment shown in FIG. 9 in that the shapes of the grips 10, 10 of the support pieces 4, 4 of the first member 1 and the second member 2 are changed. , shallow notches 13, 13 are provided in the inner protruding portions of the opposing convex shapes.

Another embodiment shown in FIGS. 11 and 12 is the first
The supporting pieces 4 of the member 1 and the second member 2 are formed so that only the front side is formed in an inclined shape as in the previous embodiment, and the back side is formed in a vertical shape. Thickness dimension E is smaller than in the previous embodiment. In addition, the support piece 4 on the back side of the first member 1
The cutout recess 14 of the second member 2 for the supporting piece 4
It is formed in the shape of a vertical narrow groove to fit into it. Note that the connection and positioning structure between the first member 1 and the second member 2 is the same as in the previous embodiment.

Another embodiment shown in FIG.
This embodiment does not have the grip portion 10 of the support piece 4 on the back side of the first member 1 and the second member 2 in the embodiment shown in FIG. Therefore, the shallow notch 13 is connected to the support piece 4 on the front side.
It is only necessary to provide the grip part 10 of the first member 1, and when the second member 2 is fitted into the first member 1 as shown by arrow B, the grip part 10 is fitted into the shallow notch 13, and both members 1,
2 is prevented from misaligning and positioned.

FIG. 14 shows a part of a door in which the first member 1 and the second member 2 described above are orthogonally connected and a panel 18 of glass plate, plastic plate, wood plate, plywood, etc. is fitted into each frame. It shows. In addition, it can be applied to various fittings other than doors (for example, shoji screens, etc.) and various furniture, etc. In particular, when decoration is required only on the front side, such as storage furniture, the embodiments shown in Figs. 11 to 13 can be applied. It is sufficient if the back side is made substantially planar as shown in FIG.

Next, in the fittings such as doors or sliding doors shown in FIG. 15 and FIG. In the figure, they are commonly fitted into adjacent frames above and below. For this purpose, as shown in Figure 17, the second
Web 12 of the first member 1 as member 2 or mid-piece
An elongated insertion window 19, which is slightly larger than the cross section of the panel 18, is provided in the panel 18. This figure 15 to 17
If the panels 18 are shared in adjacent frames as shown in the figure, there is an advantage that the panels 18 are less likely to wobble and are easier to hold.

The present invention has effectively achieved the intended purpose with the configuration detailed above. That is, in a metal frame body formed by orthogonally connecting a first member 1 and a second member 2 having support pieces 4, 4 for holding a panel 18 on the opening edge 3, the support pieces 4, At least one of the supporting pieces 4 forms an inclined edge surface 9 that slopes inward, and the supporting pieces 4,
A bent gripping portion 10 is provided at the tip of the first member 1, and a shallow notch 13 is formed only in the gripping portion 10 in the middle of the longitudinal direction of the supporting pieces 4, 4 of the first member 1. At the end surface A of the member 2, cutouts 15 corresponding to the support pieces 4, 4 of the first member 1 are formed in the support pieces 4, 4 and the central web 12,
