Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a connection mechanism for an articulated vertical frame used in a continuous window structure.

(Prior art) As a method for connecting vertical frames for continuous windows of this type,
A type that connects the left and right vertical frames with a mullion and a cover member is common.
It is known as a continuous window mounting mechanism described in Japanese Patent No. 58-55179 and Japanese Patent No. 59-54688.

Further, as a device for connecting the backbone and the vertical frame, there are known sashes described in Japanese Utility Model Application Nos. 59-60276 and 56-121867.

(Problem to be solved by the invention) In this type of conventional device, when connecting vertical frames for consecutive windows, the mullion and the cover member are screwed separately, which makes the installation work twice as much. This creates an inconvenience in that each screw connection must be aligned.

On the other hand, in the case of the former, that is, Utility Model Application Publication No. 59-60276, the connection between the backbone and the vertical frame is basically done by screws, and the screws are It is installed at the location where the shoji is installed and is located on the outdoor side, so if the shoji is attached to the vertical frame in advance, such as by fitting it, the shoji will become an obstacle and will not be installed. You can't turn the screws, and even if the shoji is sliding, the wind and rain will blow in.
There is a problem with rainwater entering through the screw. Furthermore, in this known example, since the backbone and the vertical frame are simply overlapped at the indoor and outdoor ends, when the shoji is pressed by wind and rain and that external force is applied to the vertical frame, the vertical frame's outdoor side The end portion is moved in a direction away from the backbone, thereby creating a gap between the ends and the backbone, and there is a risk that wind and rain may enter through the gap. In addition, the mounting screws are
Since it is constructed from the back side of the backbone, that is, from the side of the building support, it is inconvenient that it is impossible to connect the two after they are attached to the building.

Furthermore, in the case of a conventional method used for a bay window, it was necessary to prepare a vertical frame for a continuous window with a completely different structure depending on the protrusion angle of the bay window from the building wall.

(Means for Solving the Problems) The present invention was made in order to solve the above-mentioned drawbacks, and is basically configured so that a pair of left and right vertical frames are connected by one backbone. That is, the present invention is a corner mullion device for continuous windows in which left and right vertical frames are connected by a backbone, and the backbone connects an indoor face plate and an outdoor face board with a connecting plate, and the indoor face plate is connected to the indoor face plate. Screw receiving parts bent toward the outdoor side are formed on both sides of the face plate, first engagement grooves facing the outdoor direction are formed on both sides of the outdoor face plate, and the connecting plate has a base on the indoor side, A bifurcated branching surface portion is provided from the base to the outdoor side, and a second engagement groove facing the outdoor side is formed in the branching surface portion;
The vertical frame includes a main body extending in an indoor/outdoor direction and having an indoor side as a screw fastening part, a first engaging piece bent toward the back side on the outdoor side of the main body, and an intermediate part of the main body. a second engaging piece protruding toward the back side; and an abutting piece having the same protruding length as the second engaging piece between the second engaging piece and the screw stopper. death,
A vertical frame is arranged to face both sides of the backbone, and a first engagement piece and a second engagement piece of the vertical frame are engaged with a first engagement groove and a second engagement groove of the backbone, and the abutting In the corner mullion device for a continuous window, the piece is brought into contact with the branching surface part, and the screw-fastening part is screwed to the screw-receiving part in the facing direction of the sash.

(Function) If the vertical frames are placed opposite to each other on both sides of the backbone and the vertical frame is slid from the outdoor side to the indoor direction with respect to the backbone, the first engagement piece and the second engagement piece of the vertical frame will engage the backbone of the backbone. By engaging the first engagement groove and the second engagement groove and abutting the abutment piece against the branching surface, the two are basically locked together. and,
By screwing the screw-fastening portion to the screw receiving portion in the direction in which the sash is found, the backbone and the vertical frame are prevented from disengaging from each other, and the backbone and the vertical frame are firmly connected.

(Example) The present invention will be explained below based on the illustrated example.

FIG. 1 is a diagram showing a corner mullion device for continuous windows according to the present invention, in which vertical frames 1, 1 made of a pair of left and right long materials are connected by a backbone 11 of the same long materials.

A second engagement groove 17 facing toward the outdoor side is formed in the branch surface portion. The first engagement groove 16, the second engagement groove 17, and the screw receiving part 15 described above are connected to the first engagement piece 4, the second engagement piece 5, and the screw stop part 3 of the vertical frame 1. Needless to say, they are provided in correspondence with each other. Further, a hollow portion is formed between the branched surface portions 14b, 14b and the outdoor surface plate 13, so that the rigidity of the backbone 11 can be improved. Therefore, screw holes are provided in the branching surface portions 14b, 14b.

To connect the left and right vertical frames 1, 1 with the backbone 11,
The vertical frames 1, 1 are placed opposite each other on both sides of the backbone 11, and the first engagement piece 4 and the second engagement piece 5 of the vertical frame are inserted into the first engagement groove 16 and the second engagement groove 17 of the backbone 11. The contact piece 9 may be brought into contact with the branch surface portion 14b, and the screw portion 3 may be secured to the screw receiving portion 15 with the screw 18. This screwing is done in the facing direction of the sash. In the embodiment, the screw fixing part 3 and the screw receiving part 15 are screwed in the tightening direction, but conversely, the screw fixing part 3 and the screw receiving part 15 may be screwed in the direction in which they are separated (separated direction). good.
That is, this screw fastening consists of the first and second engagement pieces 4 and 5, which are basic engagement grooves, and the first and second engagement grooves 16,
This is done for the purpose of ensuring engagement with 17. Note that the contact portion 10 formed on the contact piece 9 of the vertical frame 1 contacts the connecting plate 14 .

In FIG. 1, when attaching the right vertical frame 1 to the backbone 11, the first engaging portion 6 of the vertical frame first engaging piece 4
is engaged with the first engagement groove 16 of the backbone 11, the vertical frame 1 is rotated clockwise using this point as a fulcrum, and the second engaging portion 7 of the second vertical frame engagement piece 5 is engaged with the first engagement groove 16 of the backbone 11. 11 second

To install it, the above should be done symmetrically.

(Effects of the invention) Since the present invention is constructed as explained above, it is possible to connect a pair of left and right vertical frames with a single backbone, and therefore the mullion and the cover member can be connected separately as in the past. It is possible to avoid the need for double installation work such as screwing the parts together, and the connection can be done extremely simply and easily as the positioning is done simply by fitting the parts together. Ta.

In this type of corner mullion device, a pair of left and right vertical frames are connected at an angle so that the outside corner is an outside corner and the inside corner is an inside corner. The contact part of the vertical frame,
:Fixing the vertical frame after contact is an essential component, but in this invention, the protruding corner and the internal corner are fixed by the interior and exterior panels of the central frame, and the vertical frame is fixed in place. The joints are connected by connecting plates on the backbone, and the two are fixed by each engagement piece on the vertical frame and each engagement groove on the backbone, as well as the screw-fastening portions on the vertical frame and the screw receivers on the backbone. As a result, each of the essential constituent parts is constructed rationally without waste, and the connecting plate of the central bone has a very simplified shape with a Y-shape formed by the base and the bifurcated branching surface. , it is possible to obtain this type of corner mullion device with a minimum number of necessary components.

Since the left and right vertical frames have a structure in which the engagement piece and the contact piece are combined with the backbone, sufficient rigidity can be obtained when joining the two, while the engagement grooves on the backbone are both facing the same direction. Directionality can be given to the attachment work of the engagement piece, and the attachment work can be performed very easily. That is, since the abutting piece and the second engaging piece have the same protruding length, they can be stably positioned with respect to these branching surfaces. By shifting the vertical frame along the vertical frame, the engagement piece and the engagement groove can be smoothly engaged, and the subsequent screwing operation between the screw fixing part and the screw receiving part can also be performed easily. Particularly, since the screw fixing part and the screw receiving part are screwed together at a position close to each other on the indoor side, the screwing operation can be performed more easily. Moreover, since the work of assembling the left and right vertical frames and the backbone can be performed one by one, it is possible to take any procedure for the work.

Moreover, the installation is basically performed by the engagement of the first and second engagement pieces of the vertical frame with the first and second engagement grooves of the backbone, and the abutment of the abutment piece against the branching surface. The engagement and positioning of the two is done, and the screwing of the screw stopper and the screw receiver only has to play the role of preventing the disengagement of the two. Overall, it becomes possible to further improve the connection rigidity.

In such a connection between the backbone and the left and right vertical frames, each of the first and second engagements, the contact by the contact pieces, and the screwing on the indoor side in order from the outdoor side,
It has a symmetrical shape and is well-balanced, so that against external forces in the expected direction (indoor-outdoor directions) (for example, wind and rain blowing from the outside at right angles to the mullion), the engagement structure mainly works in the indoor-outdoor direction. The rigidity of the sash is improved by the engagement between the barrel engagement piece and the engagement groove, and mainly by the abutment by the abutment piece and screwing on the indoor side against external force in the finding direction. be able to.

In addition, in the connection between the above-mentioned backbone and the left and right vertical frames, the first and second engagement structures are provided in order from the outdoor side, so basically the locations of the first engagement piece and the first engagement groove are If the rain breaks through, the second engaging piece and the second engaging groove are used to prevent the rain from entering, so that the intrusion of rainwater can be minimized.
