Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method of manufacturing a mullion device that connects adjacent vertical frames with 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 interposing the T-shaped mullus body between adjacent vertical frames, by attaching a mounting member to one end of the T-shaped mullion body, the adjacent vertical frames are clamped and fixed, and an eye is placed on the indoor side of the mounting member. The common structure is to attach a board and decorate it.

(Problems to be Solved by the Invention) Therefore, since the mullion device has three parts, it takes time and effort to manufacture and assemble the device, and it is also difficult to hold the device between the mullion body and the mounting member. In addition to the structure, it requires a batten to decorate the mounting members, so the expected dimensions of the mullion components inevitably become large, and as a result, at least one of the interior or exterior surfaces of the mullion is They are connected by vertical sashes and protrude from the indoor or outdoor surfaces of adjacent sashes or frames, which can cause problems, such as spoiling the appearance when configuring a continuous window in an opening in a building, for example.

Furthermore, in conventional mullion devices, the vertical frame connected to the mullion body is usually a special one arranged for connection, or a so-called internal sash that is attached to the inner circumference of the building frame. Externally mounted sashes and especially semi-externally mounted sashes, which are popular these days, have mounting fins protruding from the vertical frame that is attached to the outside of the building frame. There has never been an attempt to convert the attached and semi-external sash vertical frames into this type of mullion device. In other words, conventionally, if a mullion device is provided when constructing an external or semi-external sash, a vertical frame for the mullion device must be formed separately in addition to the vertical frame attached to the building frame. It was impossible.

The first object of the present invention is to simplify the structure of a mullion device consisting of a mullion body, mounting members, and vertical frames on both sides, and to provide a method for manufacturing a mullion device that is easy to assemble. The second purpose is to obtain a method for manufacturing a mullion device that allows the assembly of a mullion device using semi-external sashes, which has not been done in the past, by using semi-external sashes having mounting fins for the frame. There is.

(Means for solving the problem) The indoor and outdoor panels are connected in parallel to both sides of a connecting plate that is flat in the indoor-outdoor direction, and the screw receivers bent toward the outdoor side on both sides of the indoor panel are attached to the outdoor panel. A first engagement groove facing the indoor side on both sides toward the outdoor direction, and a second engagement groove facing the outdoor direction on both sides in the middle of the connecting plate are provided integrally in the longitudinal direction, respectively, in the long material. While forming bones, a screw fixing part is provided on the indoor side of the main body which is flat in the indoor/outdoor direction, and a first engagement piece is bent toward the back side on the outdoor side of the main body and protrudes toward the back side in the middle of the main body. A vertical frame having a second engaging piece and a fin at the tip of the second engaging piece is prepared, and when the vertical frame is attached to both sides of the backbone, the fin is attached to the second engaging piece. After that, the back side of the vertical frame is made to face the backbone, and the first engagement piece and the second engagement piece are engaged with the first engagement groove and the second engagement groove of the backbone, respectively. Then, the screw stopper was screwed into the screw receiver.

(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.

Since the vertical frame is for semi-external attachment and has fins, the fins are cut off at predetermined locations, so it is possible to avoid a situation where the presence of the fins hinders the connection.

(Example) FIG. 1 shows a mullion device embodying the present invention. The mullion device 1 is composed of a backbone 2 and a vertical frame 3 connected and fixed to both sides of the backbone 2. In the figure,
The one on the left is a sash for a fixed window, and the one on the right 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 to both sides of the mullion are configured symmetrically 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 a screw receiving part 7 bent toward the outdoor side on both sides, the outdoor surface plate 5 has a first engagement groove 8 facing the indoor side on both sides, and the connecting plate 6 has a second engagement groove 9 on both intermediate surfaces. 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.

Figure 3 shows one of the vertical frames 3 facing the rotating window, with a screw fastening part 13 on the indoor side of the main part that is flat in the direction of the sash, and a bent part 13 of the main part 12 bent from the outdoor side to the back side. First engagement piece 1
A second engaging piece 15 is provided at the same intermediate portion as 4 and protruding from the back side. The back side of the vertical frame means the side facing the backbone, 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 at its end edge, and the second engaging piece 15 has a second engaging part 17 at its end edge. The screwing part 13 is a part of the indoor side of the main body part 12, and the spacer protrusion 11 of the backbone 2 is attached to the indoor end of the main body part 12.
It has a bending piece 18 that is bent toward the back side.
The vertical frame of the illustrated embodiment is used for a semi-external sash, and has an auxiliary piece 19 on the main body portion 12 that also protrudes toward the back side, and has an abutment portion 20 on the edge. . Further, the second engagement piece 15 includes a fin 21 extending further toward the back side than the second engagement piece 17 at the end edge. This fin 21 is
It is used when the sash is directly attached to an opening in a building without using it as a continuous window, and when used in the mullion device 1 of the present invention, it is cut out from the broken line part. Such a vertical frame 3 is also an extrusion molded material of an aluminum alloy or a weather-resistant rigid resin, and therefore, it is similar to the first one described above.
The engaging piece 14 up to the fin 21 is formed as a continuous elongated member in the longitudinal direction. The distance between the indoor and outdoor surfaces of the formed vertical frame 3, that is, the indoor side surface of the bent piece 18 that is the indoor end surface of the main body portion 12, and the outdoor surface of the first engagement piece 14 that is the outdoor end surface of the main body portion 12. is equal to the distance between the surfaces of the indoor surface plate 4 and the outdoor surface plate 5 in the backbone 2 described above.

As shown in FIG. The first engaging portion 16 of the first engaging piece 14 and the second engaging portion 17 of the second engaging piece 15 are engaged and positioned, and the screwed portion 13 on the indoor side of the main body portion 12 of the vertical frame 3 is positioned. The mullion device 1 is constructed by screwing and fixing the countersunk screws 22 into the screw receiving portions 7 of the backbone 2. The contact portion 20 of the auxiliary piece 9 simply contacts the flat surface of the connecting plate 6.
In reality, between the vertical frames 3 and 3 on both sides arranged in parallel, the backbones 2 with their longitudinal directions aligned are fitted into the above-mentioned engaging portions and grooves, and then slid in the indoor and outdoor directions. Assemble and screw.

The spacer protruding portion 11 and the bent piece 18 form a space between the screw receiving portion and the screw fixing portion 13 to ensure fixation by the countersunk screw 22. Note that the screws are attached to the first engaging piece 1 as shown by the broken line in FIG.
4 and the extended portions of the outer walls of the first engaging grooves 8 on both sides of the outdoor surface plate 5 of the backbone 2. This extension can also be cut off when not needed.

(Effect of the invention) Since the entire backbone is integrally formed, when configuring the mullion device, only one member is prepared other than the vertical frames on both sides, and the assembly is easy. According to the method of the present invention, when each engaging portion is slid in the indoor/outdoor direction and engaged with the engagement groove, the vertical frame is accurately positioned with respect to the backbone, and the indoor side of the vertical frame is moved into the middle. The mullion device can be easily assembled by simply screwing it toward the bone.

Since 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, as in the example, the indoor side surface 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 interior and exterior surfaces of the vertical frame and the interior and exterior surfaces of the backbone can be easily made flush with each other. It can be made into something beautiful.

In the present invention, a conventional semi-external sash vertical frame having mounting fins for a building frame cannot be assembled into a mullion device as it is, or even if it is assembled, the expected width (width in the left and right direction) becomes large. However, by cutting off the fin at the tip of the second engagement piece, it becomes possible to engage the second engagement piece with the second engagement groove of the backbone. be. Therefore, the manufacturing method of the present invention makes it possible to use a semi-external sash vertical frame as a mullion device, which was previously unthinkable. The mullion device that is the result of this process has the following points: The interior wall plate of the backbone has the function of a conventional batten, and does not require a separate batten.
A mullion device with a backbone and vertical frames on both sides has the advantage of having high rigidity against bending since at least four partitioned spaces are formed inside in cross section.
