Description

[Detailed Description of the Invention] The present invention relates to a connecting device for rectangular framework bodies that constitute fittings such as doors and sliding doors.

Conventionally, in this type of rod assembly, the end faces of a pair of adjacent frames were
A pair of frames are connected at a 90° angle with their 45° end faces touching.

In order to correctly connect a pair of frames at 90 degrees without causing misalignment, a groove is formed in the corner block bent at 90 degrees, and the pair of frames is fitted into this groove. A protrusion is formed and the groove and the protrusion are fitted to properly connect a pair of frames at 90° without causing misalignment.

On the other hand, in a door in which a small window 2 is provided in the door body 1 as shown in FIG. Therefore, in order to make the corner block 7 provided in the connecting part 4 and the connecting part 6 double, a groove 8 is formed in the widthwise center of the corner block 7, and a protrusion 9 is formed in the side wall 3 of the frames 3 and 5.
It must be formed at the center in the length direction of b and 5b.

That is, the stile 3 of the door body 1 is installed so that the opening 3a faces inward, and the stile 5 of the small window 2 is installed so that the opening 5a faces outward, so the groove 8 and the protrusion 9 are installed from the center to either side. If the groove 8 and the protrusion 9 are fitted in the shifted position and the corner block 7 is provided in an out corner, the groove 8 and the protrusion 9 are fitted in the case that the corner block 7 is provided in the inner corner. corner block 7 cannot be used.

For this reason, the groove 8 can only be provided in the center of a corner block that can be used for both external and internal corners, and the protrusion 9 must also be provided in the longitudinal center of the side walls 3a and 5a of the frames 3 and 5. Since the fitting part is necessarily in the center, when the frames 3 and 5 are fitted to the corner block 7, the frame 3.5 tends to expand and deform due to the resistance of the fitting part between the groove 8 and the protrusion 9. There is a problem with this.

The present invention was developed in view of the above circumstances, and its purpose is to be able to connect the external corner connecting part and the internal corner connecting part using a common corner block, and also to make it possible to connect the external corner connecting part and the internal corner connecting part using a common corner block, and to make it possible to connect the external corner connecting part and the internal corner connecting part by using a common corner block. It is an object of the present invention to provide a connecting device for a frame body that is made difficult to expand and deform.

Embodiments of the present invention will be described below with reference to FIG. 4 and subsequent figures.

The door body 10 is provided with a small window 11.
Panels 13 are placed on both sides 12 a of the core material 12 and 12 a.
It has a structure in which a pair of panels 13 and 13 are attached to each other, and a frame body 14 is attached to the peripheral end surface of the frame body 14.
The connection part A of the inner stile 15 includes an inner stile (muntin) 15 located between and an outer stile 16 screwed to the inner stile 15.
is the protruding corner connection part.

On the other hand, the small window 11 has a structure in which a frame body 18 is provided in the opening 17 of the door body 10, and a glass 19 is fitted and attached within the frame body 18, and the frame body 18 is attached to the pair of panels 1.
3. Inner stile (kumiko) 20 located between 13, said inner stile 2
An outer stile 21 is provided with a pair of holding frames 22 and 23 which are fixed with screws to the inner frame 22 and 23 to press and support the glass 19 from the inside, and the connecting part B of the inner stile 20 is an inside corner connecting part.

The connecting portion A of the inner stile 15, which is the protruding corner of the frame body 14, is constructed as follows.

That is, the inner stile 15 is formed into a substantially U-shape with an opening 15C formed by a pair of side walls 15a, 15a and a connecting wall 15b, and is installed so that the opening 15C faces inward. The projections 24 are integrally formed in the longitudinal direction at positions closer to the connecting wall 15b than the longitudinal center position (+L) on the inner surface of the pair of side walls 15a, and the end surfaces 15'a of the pair of side walls 15a, First and second grooves 26 and 27 into which the protrusion 24 fits, and a protrusion 28 are formed on both end surfaces 25 a and 25 a of the corner block 25 bent at a right angle. The first groove 26 is formed at a position above the center position (+H) in the thickness direction and coincident with the protrusion 24, and the second groove 27 is formed at a position below the center position (+H) in the thickness direction and at the second groove 26. It is formed at a position symmetrical to the first groove 26.

The protruding portion 28 has a tapered surface 28 inclined downward in the fitting direction.
a, and is positioned above the first groove 26 and below the second groove 27.

Then, a pair of adjacent inner frames 15.15 are respectively fitted into the blocks 25 and connected via the blocks 25.

At this time, the protrusion 24 fits into the first groove 26 and plays the role of a guide, allowing the pair of inner frames 15, 15 to be reliably and easily connected correctly without causing misalignment.

Further, the protrusion 24 is located closer to the connecting wall 15 than the center position in the longitudinal direction.
Since the inner stile 15 is shaped at the b-side position, it becomes difficult for the inner stile 15 to expand and deform due to the reaction force of the fitting between the protrusion 24 and the first groove 26.

On the other hand, the connecting portion B of the inner stile 20, which is the inner corner of the frame body 11, is constructed as follows.

That is, like the inner stile 15, the inner stile 20 has a U-shape formed by a pair of side walls 20a, 20a, and a connecting wall 20b, and a protrusion 29 is formed on the inner surface of each side wall 20a. The block 25 is formed similarly to the corner block 25 described above.

Then, the corner blocks 25 are fitted into the corner blocks 25 with the pair of adjacent inner frames 20 facing upward.
Connect via 5.

At this time, the protrusion 29 of the inner stile 20 fits into the second groove 27 of the corner block 25, and as described above, the pair of inner stile 20 can be reliably and easily connected correctly without facing each other, and the inner stile 20 is It becomes difficult to expand and deform.

Since the present invention is constructed as described above, a pair of adjacent frames 15, 15, 20, 20 can be connected via the corner block 25, and the outer corner connecting portion A and the inner corner connecting portion B can be connected to each other through the common corner block 25. It can be connected using the corner block 25, and furthermore, when the stile 15.20 and the corner block 25 are fitted, the stile 15.20 can be made difficult to expand and deform.
