Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a metal frame body, and particularly to a metal lattice-like frame body for doors and shoji screens.

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,
In order to make an extremely large notch in one member, cutting was required and the cutting took time.
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 is a novel invention made in view of the above points, and is designed to enable easier work such as press working, and to ensure the positioning of two members connected orthogonally. At the same time,
The purpose is to improve the aesthetic appearance of doors, shoji, etc.

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

In Figures 1 to 4, 1 is a first member and 2 is a second member, both of which are made of metal extrusion.
It has support pieces 4, 4 that hold the panel, and the first member 1 and the second member 2 are orthogonally connected, and the door, shoji, etc.
Constructs a framework for other fittings, etc.

In FIGS. 1 and 2, the first member 1 on the upper side has a cylindrical portion 5 having a substantially square cross section, and the plate portion 5 is parallel to the surface of the parallel plate portions 6, 6 of the cylindrical portion 5. A stepped support surface 7 having a step lowered by the plate thickness dimension T of the parts 6, 6 is provided, and a tapered edge surface 8 that slopes inward is continuous on this support surface 7, and the tip of the tapered edge surface 8 is bent. A gripping portion 9 is formed in this manner. That is, the support pieces 4, 4 respectively have a stepped support surface 7, a tapered edge surface 8,
and a gripping part 9, and the cross-sectional shape is such that the opening edge 3 is gradually narrowed, and the gripping parts 9, 9 of the small strip plate piece are parallel to each other.

Further, the lower first member 1 serving as the middle support is similarly formed with a pair of support pieces 4 on the upper and lower sides, with a web 10 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 11 is formed in the middle of the first member 1 in the longitudinal direction. Specifically, only the gripping portion 9 of the support piece 4 of the first member 1 is cut out to form a shallow notch 11, and this shallow notch 11
has a flat trapezoidal shape with sloped portions 12, 12 on both sides.

Furthermore, on the end surface A of the second member 2, the support pieces 4, 4 are notched in an inverted triangular shape as shown in FIG.
A tapered notch 14 corresponding to the shape is formed. The web 10 remains in the center and protrudes to the end surface A.

Next, as shown by arrow B, the end of the second member 2 is
If the first member 1 is fitted into the shallow notch 11 and the tapered notches 14 are brought into contact with the tapered edge surfaces 8, 8, respectively, the positional shift in the direction of the arrow X in FIG.
And positioning is ensured while positional shift in the direction of the arrow Y in FIG. 2 is reliably prevented.

Also, at this time, the web 1 at the end of the second member 2
The zero protrusion is inserted between the tip gripping parts 9, 9 of the pair of support pieces 4, 4, making it even more stable. Further, the front and back protrusions 15, 15 of the second member 2 are fitted into the stepped support surfaces 7, 7 of the first member 1,
The outermost surfaces of both the front and back surfaces of the first member 1 and the second member 2 are on the same plane.

Although the end face of the second member 2 is in the shape of Mt. Fuji as shown in FIG.
This is because if the notch is made at 13, it will be formed by itself.

Next, FIGS. 5 and 6 show another embodiment, in which the shape of the shallow notch 11 of only the gripping parts 9, 9 of the first member 1 is changed so that the left and right short sides are vertical parts 12a, 12a. Correspondingly, the end surfaces of the gripping parts 9, 9 of the second member 2 are cut at right angles.

Next, in another embodiment shown in FIG. 7, the cross-sectional shape of the gripping portions 9, 9 of the respective support pieces 4, 4 of the first member 1 and the second member 2 is bulged into a substantially semicircular shape. It has a shape. In this case as well, assembly is possible as shown in FIG.

Therefore, in another embodiment shown in FIG. 8, the thickness of the second member 2 is set slightly smaller than the thickness of the first member 1, and the thickness of the first member A contact portion 16 is formed on the base plate portion of the tapered edge surface 8 of the first support piece 4, 4, and the tip end portion 15a of the second member 2 comes into contact with the contact portion 16. Of course, the tapered notch 1 of the second member 2
4 and 14 come into contact with the tapered edge surfaces 8 and 8 of the first member 1, as in the above embodiment.

Next, in another embodiment shown in FIG. 9, the thickness dimension G of the second member 2 is set smaller than the thickness dimension E of the first member 1, as will become clear when compared with FIG. 7. In addition, a stepped part such as a stepped support surface is omitted on the support piece 4 of the first member 1, and the tapered notches 14, 14 are in contact with the tapered edge surfaces 8, 8 as shown in the imaginary line,
Positioned.

Next, in another embodiment shown in FIGS. 10 and 11, the second member 2 is composed of two symmetrical sections, arranged at a predetermined distance H, and this distance H will be described later. Set it slightly larger than the wall thickness of the panel.
Then, similarly to the previously described embodiments, inverted triangular notch recesses 13, 13 are formed, and tapered notches 14, 14 are provided. On the other hand, in the first member 1, a shallow notch 11 is formed in the grip portion 9 and the tapered edge surface 8. Therefore, the deep part of the notch recess 13 fits relatively above the support piece 4 of the first member 1 .
Then, a notch recess 13 corresponding to the side of the protruding piece 15 is provided.
The vertical side of the supporting piece 4 of the first member 1 is in contact with the inner edge of the shallow notch 11, and the tapered notch 1
4 comes into contact with the tapered edge surface 8, and positioning in the left-right direction in FIG. 10 is performed.

Therefore, in FIGS. 12, 13, and 14, when shallow notches 11, 11 are formed halfway in the tapered edge surfaces 8, 8 of the support pieces 4, 4 as the first member 1 ( 10), the depth of the shallow notch 11 is determined in advance, and a protrusion 17 such as a triangle is formed on the back surface of the tapered edge surface 8 of the support piece 4 corresponding to the position of the depth. Form it. By doing this, when the shallow notch 11 is formed by cutting to the position of the imaginary line (K-K) in FIG. , there is no ``sagging'' and accurate positioning is possible. Of course, it is highly desirable to increase the number of protrusions 17 on the back surface to a plurality of pieces to form a shape material that can accommodate a plurality of notch depths, but this is not shown.

Next, if the cutting direction of the supporting pieces 4, 4 is changed by 90 degrees as shown in FIG. 15, the second member 2 will be cut as shown in FIG.
A similar good result can be obtained by increasing the thickness L that abuts the side of the protruding piece 15.

Therefore, in the fittings such as the door or sliding door (shoji) shown in FIG. 17 or 18, the connection part where the first member 1 and the second member 2 are orthogonally connected is connected to the surrounding frame M. It can be freely applied to each part shown in . Panels 18, such as glass plates, plastic plates, wood plates, plywood, etc., are fitted in common in the left and right adjacent frames in FIG. 17, and are commonly fitted in the top and bottom adjacent frames in FIG. It's embedded. To this end, as shown in FIG. 19, an elongated insertion window 19, which is slightly larger than the cross section of the panel 18, is provided in the web 10 of the second member 2.

Or, as shown in Figures 11 and 20, the second
The member 2 has a structure in which it is divided into two sections, and the panel 18 is inserted into the space H, and the panel 18 is held by the grips 9, 9 in a clamp-like manner with the gaskets 20 interposed therebetween. If the panels 18 are shared in adjacent frames as shown in FIGS. 17 to 20, the panels 18
This has the advantage of reducing "rattle" and making it easier to hold.

As described in detail above, the present invention is directed to a metal frame body formed by orthogonally connecting a first member 1 and a second member 2, each having support pieces 4, 4 for holding a panel 18 on an opening edge 3. Each of the support pieces 4 is provided with a tapered edge surface 8 that slopes inward, and a grip portion 9 formed by bending the tip of the tapered edge surface 8. , 4, a shallow notch 11 is formed only in the grip part 9 or in the taper edge surface 8 of the grip part 9, and the supporting pieces 4, 4 are formed at the end surface A of the second member. Tapered edge surface 8 of the first member 1
A tapered notch 14 corresponding to the second
The tapered notch 14 of the member 2 is brought into contact with the tapered edge surface 8 of the first member 1, and the second member 2
Since the end portion of the first member 1 is fitted into the shallow notch 11 of the first member 1 for positioning, the structure is simple, and the machining work of the connecting portion is extremely easy, and cutting work can be omitted. It is also possible to use press processing, which is suitable for mass production. Moreover, the positioning in the X direction illustrated in FIG. 1 using the shallow notch 11 and the positioning in the Y direction illustrated in FIG. It can be done. Moreover, it has the advantage that the appearance of doors and shoji screens can be beautifully finished after assembly is completed.
