DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure for connecting frame members to each other.

[0002]

2. Description of the Related Art Doors and windows installed in general houses and the like are constructed by holding various types of shoji in a rectangular frame or the like. Usually, the frame is formed by framing the upper and lower and left and right frames, and the shoji is formed by framing the upper and lower and left and right frames (these frames and frames may be combined with frame materials as necessary). Collectively). In the connection structure (connecting structure) of these frame members, the upper and lower frame members and the left and right frame members are arranged so as to be orthogonal or oblique, and the end surface of the other frame member is directly connected to the side surface of one frame member. This is done by screwing a connection screw that penetrates one frame member and reaches the other frame member.

[0003]

When the screw is screwed into the frame material as described above, the rotational force of the screw is transmitted to the frame material. Here, conventionally, since the frame members are directly in contact with each other, there is no force opposing the rotational force of the screw other than the contact resistance between the two frame materials, and thus the frame material is rotated with the rotation of the screw. May rotate together. When the frame members rotate in this way, the frame members are fixed in a twisted state, so that the frame members are distorted or the frame members are different from each other. There was a fear.

In recent years, a composite type heat insulating frame has been proposed. This heat insulation frame material is configured by covering the exposed surface of the metal frame material on the indoor side with a resin frame material, and aims to improve heat insulation properties and prevent dew condensation on the indoor side. The aim is to improve the design by eliminating visual coldness peculiar to metal and integrating it with interior decoration. In such a joint structure between heat-insulating frame materials, since a part of the frame material is formed of a resin, the frame material is easily deformed by a rotational force at the time of screwing, and a difference between the frame materials is caused. Was easy to occur. Also, the resin frame material may shrink under the influence of temperature change, but in the past, since the frame materials were just in direct contact with each other, there was a gap when the resin frame material shrank. However, there is a problem that the metal frame material is exposed, which is not preferable from the viewpoint of heat insulation and design.

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem in the conventional frame material joint structure. By preventing co-rotation at the time of frame material connection, a difference occurs between the frame materials. It is an object of the present invention to provide a connection structure for a frame material, which can prevent a gap between frame materials from being exposed and the like.

It is. In the present specification, "left" or "right"
In some cases, the case where the outdoor side is viewed from the indoor side is used as a reference. In the present embodiment, an example in which the present invention is applied to a connection structure of a shoji frame of an insulated door will be described. However, the present invention is not limited to a shoji frame but includes any frame material including a door or window frame. The present invention can be similarly applied to a connection structure, and can be similarly applied regardless of the presence or absence of a heat insulating structure. Further, the present invention can be similarly applied to not only frame members connected in an orthogonal shape but also frame members connected in an oblique shape.

In FIG. 1 and FIG. 2, an insulating door 1 has two sliding doors 4 and 5 on the outdoor side and the indoor side which are vertically movable in a rectangular frame 3 fitted into an opening 2 of a building wall. It is configured. Each of the frame members constituting the frame body 3 is a composite type frame member, and includes a metal frame 10 serving as a base and a resin frame 20 covering an exposed portion on the indoor side. A screen door 6 and a decorative lattice 7 are provided on the outdoor side of the metal frame 10.

The sliding doors 4 and 5 on the outdoor side and the indoor side are each framed in a rectangular shape by a composite frame material composed of a metal frame 30 and a resin frame 40 covering an exposed portion of the indoor side. The metal frame 30 is configured such that a metal upper frame 31, a metal lower frame 32, and left and right metal vertical frames 33 and 34 are framed in a substantially square shape, and are mutually fastened with screws. The resin frame 40 is

The upper resin frame 41 is attached to the upper metal frame 31, the lower resin frame 42 is attached to the lower metal frame 32, the vertical resin frame 43 is attached to the vertical metal frame 33, and the vertical resin frame 44 is attached to the vertical metal frame 34 with fixing screws. A composite upper frame 51, a lower frame 52, a left vertical frame 53, and a right vertical frame 54 are configured. A light-transmitting or non-light-transmitting panel 50 is accommodated in the frame framed by these frames.

The metal frame 10 and the metal frame 30 are both formed by extruded aluminum. Both the resin frame 20 and the resin frame 40 are molded from vinyl chloride, acrylic resin, or the like. By covering the exposed portion of the metal frame 10 on the indoor side with the resin frame 20 and the exposed portion of the metal frame 30 on the indoor side with the resin frame 40 as described above, the cold feeling of metal is hidden and the thermal conductivity is low. The heat insulation effect is improved by the resin. In addition, wood powder or the like can be mixed into these resin materials to give an appearance as if they were formed of wood.

Next, details of the frame structure will be described. In addition, since the sash 4 on the outdoor side and the sash 5 on the indoor side have substantially the same structure, the sash 5 on the indoor side will be described below as an example. A connection cover 6 is provided at each connection between the upper frame 51 and the left vertical frame 53 and between the upper frame 51 and the right vertical frame 54.
0 is provided. Also, a lower frame 52 and a left vertical frame 53,
In each connection part of the lower frame 52 and the right vertical frame 54,
A connection cover 70 is provided. 4 is an exploded perspective view of a main part of an upper frame and a left vertical frame, and FIG. 5 is a diagram showing the left vertical frame. FIG. 4A is a plan view, and FIG. 6 is a view showing the right vertical frame, and FIG. 6A is a plan view, and FIG. 6B is a side view as seen from the center in the direction in which the door is found.

FIGS. 7A and 7B are diagrams showing a connection cover on the upper end side, wherein FIG. 7A is a plan view and FIG. 7B is a side view. This FIG.
As shown in the figure, the connection cover 60 is composed of a fixed piece 61 and a contact piece 6.
2 are formed in a plane substantially T-shape with each other being orthogonal to each other. The fixing piece 61 is sandwiched between the frames, is formed in a flat plate shape, and has two screw holes 63. A notch 64 is formed between the fixing piece 61 and the contact piece 62. As shown in FIGS. 5 to 7, the connection cover 60 is configured such that the fixing piece 61 is brought into contact with the side of the vertical frame 53, 54 on the upper frame 51 side in a state where the contact piece 62 faces the indoor side. I have.
Then, this fixing piece 61 is screwed to the vertical frames 53, 54 with screws 65.
Are fixed to the vertical frames 53 and 54 by being screwed to the vertical frames 53 and 54. In addition, as shown in FIG.
The rib piece 53a of the vertical frame 53 is inserted into the notch 64 of the connection cover 60 fixed to.

FIGS. 8A and 8B are views showing a lower end side cover, wherein FIG. 8A is a plan view and FIG. 8B is a side view. This FIG.
As shown in FIG. 7, the connection cover 70 is provided with the connection cover 6 on the upper end side.
0, and is formed slightly longer than 0.
Similarly to the case of FIG. 0, it is provided with a fixing piece 71 and a contact piece 72 and is formed in a substantially T-shaped plane. The fixing piece 71 is provided with three screw holes 73, and the fixing piece 71 and the contact piece 72
A notch 74 is formed between. As shown in FIG. 5, when the connection cover 70 is attached to the left vertical frame 53, the cutout 74 is arranged with the notch 74 facing upward.
The rib pieces 53a of the vertical frame 53 are inserted into the notches 74. On the other hand, as shown in FIG. 6, when attached to the right vertical frame 54, the notch 74 is disposed with the notch 74 facing downward, and the rib piece 54 a of the vertical frame 54 substantially abuts the upper end of the fixing piece 71. I have. As described above, since the lower end position of the rib piece 54a differs between the left and right vertical frames 53 and 54 due to the relationship between the rib pieces 54a,
This is achieved by changing the direction of the connection cover 70. Further, since the connection cover 70 is attached in different directions as described above, the fixing piece 71 has three screw holes 73 as described above.
Are fixed to the vertical frames 53 and 54 by screwing a screw 75 into a screw hole 73 at the center thereof.

Next, the work of connecting the upper frame 51 and the vertical frame 53 will be described. The upper frame 51 and the vertical frame 54 are bilaterally symmetric, and the lower frame 52 and the vertical frames 53 and 54 are substantially symmetrical with respect to the vertical frame. As shown in FIG. 4, in a state where the connection cover 60 is fixed to the side surface of the vertical frame 53 on the side of the upper frame 51 via the screw 65, the upper frame 51 is attached to the side surface of the vertical frame 53 (the side surface of the fixing piece 61). The upper frame 51 and the vertical frame 53 are connected to each other by screwing a fixing screw 66 that passes through the vertical frame 53 and the fixing piece 61 from the outside into the screw hole 51 a of the upper frame 51.

At the time of this connection, when the frame members are brought into contact with each other, the contact piece 62 of the connection cover 60 is moved to the upper frame 5.
1 indoor side surface 51b and indoor side surface 5 of vertical frame 53
3b. Therefore, when the fixing screw 66 is screwed in, even if the rotational force is transmitted to the upper frame 51 and the vertical frame 53, the relative movement of the upper frame 51 and the vertical frame 53 is regulated by the interposition of the contact piece 62. Therefore, the upper frame 51 and the vertical frame 53 do not rotate together. Therefore, there is no difference between the upper frame 51 and the vertical frame 53.
Further, when the upper resin frame 41 or the like shrinks due to a change in heat or the like, a gap is generated by the shrinkage, and the upper metal frame 31 is exposed, but this exposed surface is covered with the contact piece 62. Therefore, the design can be maintained by exposing the metal portion to the indoor side so as not to be exposed.
In particular, when the contact piece 62 is formed of resin, the exposed surface of the upper metal frame 31 is covered with resin, so that heat insulation can be maintained.

Next, an airtight structure between the upper frame 51 and the vertical frame 53 will be described. The upper frame 51 and the vertical frame 54 are bilaterally symmetric, and the lower frame 52 and the vertical frames 53 and 54 are substantially symmetrical with respect to the vertical frame. As shown in FIGS. 4 to 6, the fixing piece 61 of the connection cover 60 is formed to have a width smaller than that of the vertical frame 53, and a sealing material 80 is provided on the outdoor side of the fixing piece 61. . The sealing material 80 is formed of an elastic foamed resin body or the like, and as shown in FIG.
The upper frame 51 and the vertical frame 53 are formed as shown in FIG.
Are compressed to a thickness substantially corresponding to the mutual interval between the upper frame 51 and the vertical frame 53. As described above, since the gap generated by providing the connection cover 60 can be closed by the sealing material 80, airtightness and heat insulation can be maintained.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and may be implemented in various forms within the scope of the technical idea. First, the contact piece is described as being fixed to the vertical frame, but may be fixed to the upper and lower frames. That is,
It can be fixed to any one of the two frame members to be connected. For example, as shown in FIG. 9, when connecting each frame in a horizontal manner, a port cover 60 is fixed to the lower surface of the end of the upper frame 51, and the port cover 60 is attached to the vertical frame with fixing screws 66. 53 may be fixed.

Although the abutment piece has been described as abutting on both side surfaces of the vertical frame and the upper and lower frames, at least two of the two frame materials to be connected other than the frame material to which the connection cover is fixed. Any material may be used as long as it comes into contact with the side surface of the frame material. For example, FIG.
As shown in FIG. 0, when the connection cover 90 is fixed to the vertical frame 53, the contact piece 92 may be formed so as to contact only the side surface of the upper frame 51. Also in this case, if the fixing piece 91 is firmly fixed to the vertical frame 53, the movement between the frames can be restricted. However, when the contact pieces are brought into contact with the side surfaces of the both frames as in the above-described embodiment, even when the fixing force between the vertical frame and the door cover is weak, the mutual movement can be prevented.

Further, the contact position of the contact piece may be any other side surface instead of the indoor side surface of the frame. For example, even in the case of contact with the side surface on the outdoor side, it is possible to prevent mutual movement of the frames. However, by abutting the side surface on the indoor side, it is possible to close the space between the frames to be exposed on the indoor side and maintain the design property and the heat insulating property. In addition, it is not always necessary to sandwich the door cover between the upper frame and the vertical frame. For example, the door cover may be arranged on the upper surface or the lower surface of the upper frame. For fixing the frame and the connection cover, an arbitrary structure such as bonding may be adopted other than the fixing screw.
