Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting device used for connecting ends of two members by abutting against each other.

[0002]

2. Description of the Related Art A structure in which the ends of a two-member frame member are butted against each other can be found in various fields. There are two types of connection, one is linear and the other is connected at an angle. For example, structures that connect at an angle often appear at so-called corners of joinery. FIG. 8 shows the door panel 1, in which frame members (frame members) 4 (a, b) are mounted around the openings 2 and 3 that both serve as decoration and lighting, and the frame 4 (a,
The ends of b) are connected at a right angle or at an angle of 120 ° to form corners (A, B).

As shown in FIG. 9, such a corner portion is formed by abutting the angled ends of the frame members 4 (a, b) on both sides, and applying a simple connecting metal fitting 5 bent at the corner portion angle, The screws 6 are attached to the frame members 4 (a, b) on both sides, and the connecting screw 7 is screwed and fixed from one frame member 4 a to the other frame member 4 b.

However, in such a joint structure, since the connecting screw 7 is not orthogonal to the abutting surface p of the frame members 4 (a, b) on both sides, when the connecting screw 7 is screwed in, the frame members on both sides are screwed together. Four
Slip occurs along the abutting surface between (a, b), and misalignment (step) occurs at the outer edge and inner edge of the corner portion. Also,
Since there is no portion that suppresses so-called twist in which the other frame member 4b rotates about the connecting screw 7 with respect to the one frame member 4a, sufficient caution is required for the connecting work.

The frame in the openings 2 and 3 is composed of the members 8 (a, b) which are divided into the front and back sides.
As described above, they are arranged on both front and back surfaces of the door plate 9 around the opening, and are integrated by the screw 10 screwed from the member 8b. Reference numeral 11 is a glass fitted in the opening. Further, in this example, the coupling fitting 5 is used to connect the frame members 4 (a, b) on the member 8a side.

Japanese Unexamined Patent Publication No. 58-20888 and Shokai Sho 6
In JP-A 3-138393, a main body (coupling metal 7, angle member 4) and a fastening bolt (bolt 14, fixing bolt 5) are disclosed.
A joint structure in which the fastening bolts are penetrated through the frame members 4 (a, b) on both sides in a direction substantially orthogonal to the abutting surface, and the frame members 4 (a, b) on both sides are drawn together via a coupling fitting to be joined. Is disclosed.

In this structure, the frame members 4 (a, b) on both sides are unlikely to cause misalignment due to sliding along the abutting surfaces,
One frame member 4a may be twisted to rotate with respect to the other frame member 4b. This twisting can be prevented to some extent if the width of the groove and the width of the main body are made to substantially coincide with each other by making the portions of the frame members 4 (a, b) on both sides where the fittings are mounted as grooves. It is necessary to make a groove structure in the part where the metal fitting is attached.

Such problems generally occur not only in connecting frame members but also in connecting members by screwing, and in addition to connecting members forming corners, connecting members connected in a straight line. It also occurs between.

[0009]

SUMMARY OF THE INVENTION An object of the present invention is to provide a two-member connecting device having a versatile structure that is unlikely to cause misalignment or twisting when connecting members by screwing.

[0010]

The connecting device of the present invention comprises:
It shall be equipped with a main body, a drawing screw and a joining screw.
The main body divides both ends into first and second attracting portions, and between the attracting portions into first and second abutting portions, and at least the attracting portions on both sides in the same direction from the abutting portions. Fold. as a result,
These are the first and second attracting portions facing each other. The main body is often made by bending a single relatively sturdy sheet metal (steel plate) by pressing.

Two members whose ends are butted (frame members, etc.)
In the meantime, the main body is brought into contact with the surface of the member where the first and second contact portions are abutted, and the first and second attracting portions are exposed from the abutted member and are attached to face each other. The first and second attracting portions are attracted with an attracting screw. After bringing the first and second abutting parts into a state where they are sufficiently drawn,
Bolts) to the member.

In order to expose the first and second attracting portions from the member while the first and second abutting portions are brought into contact with the surface of the member, the first and second abutting members are provided on both sides. It is necessary to provide a hole for penetrating the second attracting portion.

When the main body is mounted between the members on both sides and the first and second attracting portions are attracted by the attracting screw, the end portions of the both side members are attracted and the abutting surfaces are brought into close contact with each other. Then, while maintaining this state, the first and second contact portions are fixed to the member with the joining screws, and the mounting surfaces of the main body of the both side members coincide with the contact portions of the main body. Twisting at is eliminated.

In the main body, each of the first and second abutting portions may be provided with a fixing piece bent from one side perpendicular to the abutting portion. It can be used when the frame members on both sides to be connected have a surface perpendicular to the surface with which the abutting portion of the main body contacts. A member in which the contact portion of the main body is brought into contact with the surfaces of the members on both sides and the first and second attracting portions projected from the member are attracted by the attracting screw, and then the fixing piece is butted by the joining screw. Fix on a vertical surface. Since the fixing piece corresponds to each of the members on both sides, if the fixing piece is fixed to the vertical surface of the member with the joining screw, the vertical portions of the members on both sides are aligned on the same surface,
The twist is eliminated.

A groove-shaped engaging portion parallel to the width direction of the abutting portion (direction intersecting the attracting screw) is provided at or near the bent portion of the abutting portion and the abutting portion in the main body, and the pulling operation is performed. In some cases, a part of the width direction of the member (direction intersecting the pulling screw) is engaged with the engaging portion to fix the main body. By fixing a main body by engaging a part of the member in the width direction with the engaging portion, the surfaces of both side members are unified with the surface of the main body at this part, and twisting is eliminated.

In some cases, the first and second abutting portions may be bent at partition portions on both sides. The bending angle is made to coincide with the angle of the corners of both side members to be connected.

1 to 3 show a door panel 1 of FIG.
3 shows a portion of the opening 2 corresponding to the frame member 4 (a, b) (frame member). The frame members 4a and 4b are cut at their ends so that the corner angle is 120 °, and the vertical through holes 12 (a and b) are provided near the ends of both frame members 4 (a and b). ) Is provided (FIG. 3). Further, the cross section has a rising portion on the front side. The two-member connecting device 13 in FIG. 1 is a first example, and is composed of a main body 14, a drawing screw 15, and a joining screw 16 (screw, bolt).

The main body 14 is formed by bending a single steel plate having a thickness of 1.6 mm by press working, and has first and second attracting portions 17 and 18 at both ends, and a first portion between them. It is divided into the second contact portions 19 and 20, and the attracting portions 17 and 18 are bent downward from the contact portions 19 and 20 so that the first and second attracting portions 17 and 18 face each other. In addition, the first and second contact portions 19, 20 are respectively contacted with the contact portions 19, 2 from one side.
The first and second fixing pieces 21 and 22 are bent and provided perpendicularly to the 0 plane. The first attracting portion 17 has a attracting screw 1
The female screw 23 to which 5 is screwed is cut, and the second pulling portion 18
The through hole 24 of the pulling screw 15 is formed in the first,
The second fixing pieces 21 and 22 also have through holes 25 through which the joining screws pass (FIG. 2).

The two-piece connecting device 13 is used as follows. The ends of the frame members 4 (a, b) on both sides are butted.
The facing attracting portions 17 and 18 of the main body 14 are respectively inserted into the through holes 12 (a, b) of the frame member 4 (a, b) so as to project downward. At the same time, the first and second contact portions 1 of the main body 14
9 and 20 are brought into contact with the upper surfaces of the corresponding frame members 4 (a, b), and the first and second fixing pieces 21 and 22 are arranged along the rising portions of the respective frame members 4 (a, b). Let

Opposing first and second attracting portions 17, 18
Attach the pulling screw 15 in between and screw in. Then, the first and second attracting portions 17, 18 approach each other, and the frame members 4a,
Since the edges S1 and S2 of the through hole 12 (a, b) in 4b are pressed, the abutting surfaces of the frame members 4 (a, b) on both sides are in close contact. At this time, the vertical positions of the edges S3, S4 on the corners of the frame members 4 (a, b) on both sides are located at the bent portion between the first and second contact portions 19, 20. Is regulated, and there is no difference.

After the pulling work is completed, the first and second fixing pieces 21, 22 are fixed to the rising portions of the corresponding frame members 4 (a, b) by the joining screws 16, 16. As a result, the twisting of the frame members 4 (a, b) on both sides is eliminated at the corner side of the corner portion. Since the position of the joining screw 16 screwed into the rising portion from the fixing pieces 21 and 22 is located away from the contact portions 19 and 20, the action of eliminating the twist is great, and the corner portion is also reinforced.

According to this structure, the end faces of the two side frame members 4 (a, b) are brought into contact with each other by screwing in the pulling screw 15, and the both side frame members 4 are rotated by screwing in the joining screw 16. Since the twist between (a, b) is eliminated, a clean corner can be created. Since the joining screw 16 is used to eliminate the twist, the contact portions 19, 2 are provided on the frame member side.
It does not require a groove structure for restricting 0 in the width direction and is highly versatile.

FIGS. 4 and 5 show a second example of the two-member connecting device 13, which has substantially the same structure as the first example, but has fixing pieces 21 on the first and second abutting portions 19, 20. , 22 are not provided, and the through holes 25 are formed in the first and second contact portions 19, 20. The method of using the connecting device 13 is almost the same as that of the first example, but after the pulling operation, the joining screw 16 is directly connected to the frame member 4 (a, a) from the first and second contact portions 19, 20. Screw it into the upper surface of b). As a result, the inclination of the upper surfaces of the frame members 4 (a, b) on both sides is unified in conformity with the inclination (horizontal) of the surface of the main body 14, so that twisting of the frame members 4 (a, b) on both sides is eliminated. It

FIGS. 6 and 7 show a third example in which a two-member connecting device 13 is composed of a main body 14 and a drawing screw 15 and is not provided with a joining screw 16. The main body 14 includes the attracting portions 17, 18
And the bent portions of the contact portions 19 and 20 each have a groove-shaped engaging portion 26 (a, b) parallel to the width direction of the contact portion (direction intersecting the pulling screw). The engaging portion 26 (a, b) is
It is formed so as to open inside the bent shape of the main body 14. Other configurations are not different from those of the first and second examples.

In this connecting device 13, first, the main body 14 is
From the through holes 12 (a, b) of the frame members 4 (a, b) arranged on both sides with their ends abutted to each other, the first and second pulling portions 17,
18 is made to protrude, and the 1st, 2nd contact parts 19 and 20 are made to contact | abut to the upper surface of the frame material 4 (a, b) of both sides, respectively, and are attached. Then, pull in the pulling screw 15 to fix the frame members 4 on both sides.
The ends of (a, b) are drawn close together. At this time, the through hole 12 (a, a) is formed in the groove-shaped engaging portion 26 (a, b) provided in the bent portion of the attracting portions 17, 18 and the abutting portions 19, 20.
The edges S1 and S2 of b) are made to be widely engaged in the width direction.

With this structure, the end portions of the frame members 4 (a, b) on both sides are brought into close contact with each other by screwing in the pulling screw 15, and the groove-shaped engaging portion 26 is formed.
Edge S1 of the frame member 4 (a, b) engaged with (a, b),
Since S2 is not allowed to rotate due to the engagement with the groove, twisting does not occur at the time of drawing and the joining screw 16 is not required. As a result, it is possible to reduce the work amount for managing and connecting the parts. Moreover, the engagement state between the edges S1 and S2 and the engaging portion 26 is such that the pulling portions 17 and 18 are moved as the pulling proceeds.
Since the amount of bending of the contact portions 19 and 20 is increased, the strength is further increased, and it is easy to obtain a twisted connection state. The groove-shaped engaging portion 26 (a, b) is not only a bent portion,
It may be a structure provided in the vicinity thereof.

Although the frame of the door panel has been described above as an example, the present invention can be applied to other frame structures. Further, although it has been described that the abutting of the end portions is made to a corner portion having an angle, it is also applicable to a case where members on both sides are connected in a straight line.

[0028]

According to the structure of the first aspect, the members on both sides can be connected to the abutting ends without misalignment or twisting. Since the joining screw is used to eliminate the twist, a groove or the like for restricting the position of the main body of the connecting device of the two members is not required on the member side, and the versatility as a connecting device of the two members is high. According to the configuration described in claim 2, the twist between the both side members can be efficiently eliminated by the fixing piece. Further, the fixing piece has the effect of reinforcing the connecting portion.

According to the third aspect of the present invention, since no connecting screw is required, the number of parts to be managed and the amount of work for connection are reduced. According to the configuration of claim 4, it can be used as a connecting device for two members of a corner portion, and a clean corner portion connecting structure without misalignment or twisting can be obtained.
