Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a mullion device that connects adjacent vertical frames using a continuous window or the like.

(Prior Art) This type of mullion device, for example, as in the one described in Publication of Utility Model Publication No. 55-5653, consists of three members: a mullion body that is approximately T-shaped in cross section, a mounting member, and a decorative batten. After a T-shaped mullus body is interposed between adjacent vertical frames, a mounting member is attached to one end of the T-shaped mullion body to clamp and fix the adjacent vertical frames, and an eye is placed on the indoor side of the mounting member. The common structure is to attach a board and decorate it.

Therefore, since the mullion device consists of three parts, it takes time and effort to manufacture and assemble it, and the structure is such that it is held between the mullion body and the mounting member, and the mounting member is decorated. Since battens are required, the expected dimensions of the constituent parts of the mullion inevitably become large, and as a result, at least one of the interior or exterior surfaces of the mullion is connected by the mullion to the adjacent sash or frame. They protrude from the indoor or outdoor surfaces of the body, and have the disadvantage of causing inconveniences such as, for example, when configuring a continuous window in an opening of a building, the appearance may be impaired.

(Problems to be solved by the invention) The object of this invention is to simplify the structure of the mullion device, which consists of a mullion body, mounting members, and vertical frames on both sides, and to provide a mullion device that is easy to assemble. .

(Means for solving the problem) Connect the indoor and outdoor panels in parallel to both sides of a connecting plate that is flat in the indoor-outdoor direction, and connect the screw receivers bent toward the outdoor side on both sides of the indoor panel to the outdoor panel. A long material having first engagement grooves facing the indoor side facing the outdoor direction on both sides, and second engagement grooves facing the outdoor direction on both sides in the middle of the connecting plate, respectively, integrally provided in the longitudinal direction. A first engagement piece bent toward the back side on the outdoor side of the main body, and a second engagement piece protruding toward the back side in the middle of the main body. It consists of a vertical frame each equipped with a mating piece and an auxiliary piece having the same protrusion length as the second engaging piece, the vertical frame is placed on both sides of the backbone, the back surface of the vertical frame is opposite, and the first engaging piece , the second engaging pieces are respectively engaged with the first engaging groove and the second engaging groove of the backbone, the auxiliary pieces are brought into contact with the connecting plate, and the screwing part is screwed into the screw receiving part to form a mullion. Configure the device.

(Function) The backbone and the vertical frames on both sides are connected to form a mullion device as a whole. The first engagement groove and the second engagement groove of the backbone engage the vertical frame to determine the position, and the screwed part is
Fix the backbone and vertical frame. The interior and exterior panels of the backbone also function as battens.

(Embodiment) FIG. 1 shows a first embodiment, in which a mullion device 1 is composed of a backbone 2 and a vertical frame 3 connected and fixed to both sides thereof. In the figure, the left side is a sash for a fixed window, and the right side is a sash for a rotating window. In this case, the vertical frames 3 on both sides of the backbone 2 are vertical frames for different types of sashes. Note that the vertical frame is not limited to a vertical frame of a window sash, but may also be a vertical frame of a door frame. However, the back surfaces of the vertical frame 3 fixed on both sides of the mullion are configured to be symmetrical on both sides.

As shown in FIG. 2, the backbone 2 has an indoor side plate 4 and an outdoor side plate 5 arranged in parallel, and is connected to both sides of a connecting plate 6 which is flat in the indoor/outdoor direction.
has screw receiving portions 7 bent toward the outdoor side on both sides, and the outdoor surface plate 5 has first engagement grooves 8 facing toward the indoor side and outdoors on both sides thereof,
Furthermore, the connecting plate 6 has second engaging grooves 9 on both sides in the middle. The second engagement groove 9 in the connecting plate 6 faces the outdoor side like the first engagement groove 8, and the outdoor side of these first and second engagement grooves is enlarged to form a connecting frame. The edges of the body are easier to engage. These screw receiving portions 7 and first and second engagement grooves 8 and 9
are provided in the longitudinal direction of the backbone 2.

In addition, in FIG. 2, the reference numeral 10 in the middle of the connecting plate 6 is a screw hole, and the reference numeral 11 is a spacer protrusion formed on the outdoor side end of the screw receiving part 7 in both directions. Back bone 2 with the above structure
The whole can be formed as an integral long material by extrusion molding of aluminum alloy or weather-resistant hard plastic.

FIG. 3 shows one of the vertical frames 3 facing the revolving window, and this vertical frame 3 has a screw fastening part 13 on the indoor side of the main body part which is flat in the direction of the sash, and a screw fastening part 13 on the outdoor side of the main body part 12. A first engagement piece 14 bent toward the back side, a second engagement piece 15 formed to protrude toward the back side at the middle portion of the main body, and an auxiliary member having the same protruding length as the engagement piece 15. A piece 19 is provided. The back side of the vertical frame means the side facing the backbone, which is opposite to the side on which the shoji is built.

The first engaging piece 14 has a first engaging part 16 bent toward the indoor side on its edge, and the second engaging piece 15 has a second engaging part 17 on its edge. The screwing part 13 is a part of the indoor side of the main body part 12, and has a bending piece 18 bent toward the back side, which corresponds to the above-described spacer protrusion 11 of the backbone 2, at the indoor end. Note that the auxiliary piece 19 has an abutment portion 20 on the edge.
have. Further, the second engaging piece 15 may include fins 21 that extend further toward the back side than the second engaging portion 17 at the end edge. This Finn 2
1 is used when the sash is not used as a continuous window but is directly attached to an opening in a building, and is unnecessary when used in the mullion device 1 of the present invention, so it is cut out from the broken line part. Such a vertical frame 3 is also an extrusion molded material of aluminum alloy or weather-resistant synthetic resin, and therefore, the first engaging piece 14 and up to the fin 21 are continuous in the longitudinal direction as a long member. It is formed. The indoor and outdoor surfaces of the formed vertical frame 3, that is, the indoor side surface of the bent piece 18 that becomes the indoor end surface of the main body portion 12, and the first
The distance between the engagement piece 14 and the outdoor surface is the same as the above-mentioned backbone 2.
The distance between the surfaces of the indoor surface plate 4 and the outdoor surface plate 5 in

As shown in FIG. 1, the backbone 2 and the vertical frames 3 on both sides of the backbone 2 are connected to the first engagement groove 8 and the second engagement groove 9 of the backbone 2 on both sides of the backbone 2. The first engagement piece 14
The engaging portion 16 and the second engaging portion 17 of the second engaging piece 15 are respectively engaged, and the countersunk screw 22 is inserted into the screw of the backbone 2 from the screwing portion 13 on the indoor side of the main body portion 12 of the vertical frame 3. The mullion device 1 is constructed by screwing and fixing into the receiving portion 7. Contact portion 2 of auxiliary piece 19
0 simply contacts the plane of the connecting plate 6.

In reality, the backbone 2 is used when connecting unit window bodies framed by upper, lower, left, and right frames, that is, when forming continuous windows in the unit window bodies. In other words, the unit window bodies are arranged side by side, the backbone 2 is held between the opposing vertical frames 3, 3, and the engaging portion and engagement groove between the vertical frame 3 and the backbone 2 of one unit window body are placed. After aligning the two, move them both indoors and outdoors and assemble them, and then screw them together. Furthermore, the vertical frame 3 of the other unit window body
and the backbone 2 are assembled in the same manner and screwed together. Then, the left and right unit window bodies are connected via the backbone (continuous window).
After that, this continuous window body is installed in the opening of the building.

In the continuous window, the spacer protrusion 11 and the bent piece 18 form a space between the screw receiving part and the screw fixing part 13 to ensure fixation by the countersunk screw 22. In addition, as shown by the broken line in FIG. 1, the screws must also be tightened between the first engaging piece 14 and the extended portion of the outer wall of the first engaging groove 8 on both sides of the outdoor surface plate 5 of the backbone 2. There is. This extension can also be cut off when not needed.

(Effect of the invention) Since the entire backbone is integrally formed, when constructing a mullion device, only one member is prepared other than the vertical frames on both sides, and the vertical frames and When assembling the backbones, the moving distance during connection can be shortened by arranging them facing each other and moving them both indoors and outdoors. Since the two vertical frames that are connected via the backbone are each a constituent frame of a unit window body, it is actually very meaningful to shorten the distance traveled between the vertical frame and the backbone when they are connected. be. Then, with the indoor side of the vertical frame facing the backbone,
Since it is only necessary to fasten screws at certain points, it is easy and requires no effort, as it can be done in close proximity.

The first engagement groove of the backbone is located on the indoor side on both sides of the outdoor exterior surface plate, and the screw receiving part is located on the outdoor side of the interior surface board, so that, as in the example, the indoor and outdoor surfaces of the vertical frame and the backbone If the distance between the indoor and outdoor surfaces is equal,
When the vertical frame is assembled to the backbone, the indoor and outdoor surfaces of the vertical frame and the inner and outer surfaces of the backbone can be easily made flush with each other. It can be made into something.

The interior panel of the backbone has the function of a conventional batten and does not require a separate batten. Since the first engagement groove in the outdoor surface plate and the second engagement groove in the connection plate are shifted in position in the left-right direction, rainwater that has entered from the first engagement part can be removed from the connection plate or the vertical frame. Since it reaches the second engaging portion via the back surface, it is possible to reduce the amount of rainwater entering the room.

A mullion device consisting of a backbone and vertical frames on both sides has at least four partitioned spaces in the cross section, so it has high rigidity against bending. Furthermore, since the vertical frame is provided with auxiliary pieces having the same protruding length as the second engaging pieces, when this vertical frame is assembled from both sides to the backbone, these second engaging pieces and the auxiliary piece are positioned so as to sandwich the connecting plate of the backbone from each other. Therefore, even if some external force is applied to the mullion device of the present invention and the mullion tries to curve in either the left or right direction, the stress applied to the second engagement piece and the auxiliary piece of one vertical frame will be applied to the backbone of the mullion. Since it is received by the second engaging piece and the auxiliary piece of the other vertical frame via the connecting plate, together with the rigidity maintained by the four compartment spaces mentioned above, it is possible to resist this stress that tends to curve. deformation of the member can be prevented. In this case, since the external force is received by the second engaging piece and the auxiliary piece of the vertical frame, the connecting plate of the backbone may be a flat thin plate. Therefore, in the combination of the backbone and the left and right vertical frames, the dimension (the dimension in the left-right direction) is substantially equal to the dimension of the left and right vertical frames combined, and the mullion itself is made more compact.
