Description

[Detailed description of the invention] [Industrial application field] The present invention is interposed between the door body of a hinged door and a sleeve panel that fits in to reinforce the sleeve panel, and at the same time, the door body of the movable part This invention relates to door mullions used to improve the fit of fixed part sleeve panels.

[Prior art]

Doors installed at entrances and exits, such as entrances, may have a relatively narrow sleeve panel attached to the door body in order to obtain sufficient lighting. In this case, a mullion is installed between the door body and the sleeve panel. This is done to reinforce the sleeve panels and to improve the fit between the door body and the sleeve panels.

FIG. 3 is a cross-sectional view showing a conventional example of an entrance door in which a mullion is provided between the door body and the sleeve panel.

In the figure, 1R and 1L are the left and right vertical frames of the door frame provided along the opening of the entrance, 2 is the door body of the hinged door that is attached to one vertical frame 1R with a hinge etc., and 3 is the door body of the hinged door. The sleeve panel 4 is fixed to the other vertical frame part 1L, and 4 is the door body 2 and the sleeve panel 3.
This is a mullion that is interposed between and reinforces the sleeve panel 3.

This mullion 4 is made of a hollow cross-section member such as an aluminum extrusion molded into a prismatic shape, and its front side protrudes slightly forward from the surfaces of the door body 2 and sleeve panel 3, which are the facing surfaces of the door. It was erected in
One side surface is engaged so as to abut along the prospective surface of the sleeve panel 3 to fixedly support the side end portion of the sleeve panel 3, and a matching portion 5a provided on the door body 2 on the other side surface. A matching portion 5b corresponding to the door is protruded to improve the fitting of the door body 2 and the sleeve panel 3.

[Problems with conventional technology]

By the way, many customers who purchase entrance doors dislike the appearance in which the mullion 4 is exposed between the door body 2 and the sleeve panel 3 because they think it looks bad.

Also, depending on the user's preference, the entrance door may be made into a double door by providing a child door that can be opened and closed instead of the sleeve panel 3, and this child door and sleeve panel 3 are unified with the door body 2. Usually, it has a unique design.

However, in the case of a child door, the child door and the door body 2 can be combined without a mullion like a freely swinging door, but in the case of a sleeve panel 3 that fits together, the sleeve panel 3 must be reinforced or the door Since it is necessary to insert a mullion 4 between the door body 2 and the door body 2 in order to fit it well with the main body 2, if the opening area of the entrance is the same, the width of the sleeve panel 3 should be made wider than that of the child door. It is necessary to select a width smaller than 4. Therefore, the sleeve panel 3 and the child door had to be manufactured separately in different sizes, which was a hassle.

[Purpose of invention]

Therefore, the present invention makes it possible to prevent the mullions interposed between the door body and the sleeve panel from being exposed on the facing side of the door, and also to reduce the width of the sleeve panel when installed in an entrance etc. with the same opening area. We provide a door mullion that can be selected to have the same dimensions as the door width, improving the visibility of the entire door and improving its appearance. At the same time, we make the sleeve panels and child doors compatible and manufacture them separately. The purpose is to eliminate the hassle.

[Structure of the idea]

In order to achieve this objective, the present invention provides a door mullion that is interposed between the door body of a hinged door and a fitted sleeve panel to reinforce the sleeve panel.
a support plate fixedly supporting a side end of the sleeve panel along a prospective surface of the columnar mullion body that stands on the back side of the door close to the gap between the door body and the sleeve panel; It is characterized by a protruding portion.

[Effect of invention]

According to the present invention, a columnar mullion body is erected on the back side of the door, and the support plate portion protruding from the mullion body fixedly supports the side end portion of the columnar mullion body along the expected surface of the sleeve panel. Therefore, the distance between the door body and the sleeve panel is sufficient by ensuring only the thickness of the support plate that supports the sleeve panel and a small gap necessary for opening and closing the door body. The sleeve panels can be placed close together like double doors without mullions.

Therefore, the pillar-shaped mullion body is not exposed on the facing side of the door and the overall appearance of the door is not deteriorated, and at the same time, the width of the sleeve panel can be attached to an opening with the same opening area so that it can be opened and closed. It can be formed to have the same width as the child door to be compatible with the child door.

〔Example〕

Hereinafter, embodiments of the present invention will be specifically described based on the drawings.

FIG. 1 is a cross-sectional view showing an example of a mullion according to the present invention and an entrance door using the mullion.

Note that parts common to those in FIG. 3 are given the same reference numerals and detailed explanations are omitted.

The mullion 4 according to the present invention includes a door body 2 of a hinged door,
A columnar mullion main body 4a stands on the back side of the door close to the gap S between it and the sleeve panel 3.
A supporting plate portion 4b is provided protruding along the facing surface 6 of the sleeve panel 3 to fixedly support the side end portion thereof.

Here, the door body 2 has a frame formed of a square pipe 7 made of extruded aluminum, and on the outside of the frame, a front cover 8 and a back cover 9 made of steel plates or the like are respectively provided with excellent heat insulation and airtightness. They are attached via sealing materials 10, 10, . . . made of vinyl chloride resin or the like.

Further, the sleeve panel 3 also has a frame formed of a rectangular pipe 11 with an L-shaped cross section made of extruded aluminum, and the outer side of the frame is made of the same material as the front cover 8 and back cover 9 of the door body 2. A front cover 12 and a back cover 13 having a uniform design are attached via sealants 10, 10, . . . , respectively.

The mullion 4 has a supporting plate part 4b vertically protruding through a heat insulating material 14 made of urethane or the like attached to the central part of the front side of the mullion main body 4a, and the supporting plate part 4b is provided on one side of the mullion main body 4a. Projections 16, 16 that fit into the engagement grooves 15 provided on the facing surface 6 of the sleeve panel 3
is formed, and a sleeve panel 3 is formed on the tip side.
A hook 17 is formed to be hooked on the corner of the front surface of the sleeve panel 3 to fixedly support the side end of the sleeve panel 3. An engagement groove 20 is formed on the other surface of the support plate portion 4b for attaching a leaf spring-like rubber gasket 19 that slides in airtight contact with the facing surface 18 of the door body 2.

In addition, the mullion main body 4a has protrusions 21 on the left and right sides of the support plate portion 4b that abut along the back surface of the sleeve panel 3, and a back cover 9 of the door main body 2 made of a steel plate or the like is magnetically attracted. An engagement groove 23 for attaching a magnetic bead 22 is formed, and the protrusion 21 reinforces the sleeve panel 3 from the back side as well, and the magnetic bead 22 is attached to the mating portion 5a provided on the door body 2.
It has become a matching section 5b corresponding to this.

The joining part 5a of the door body 2 is formed of a substantially L-shaped metal plate, and its tip protrudes slightly forward from the facing surface 24 of the door to form a hook 17 that forms the tip of the support plate part 4b. In addition, a protrusion 26 is formed on the plate portion constituting the prospective surface 18 of the door main body 2 to fit into an engagement groove 25 provided along the square pipe 7.

The above is an example of the configuration of the mullion 4 according to the present invention and an entrance door using the mullion 4. Next, the operation and effects thereof will be explained.

First, the mullion 4 has a columnar mullion main body 4a erected on the back side of the door close to the gap S between the door main body 2 and the sleeve panel 3, and a support plate protruding from the mullion main body 4a. Since only the portion 4b is interposed between the door body 2 and the sleeve panel 3, the distance between the door body 2 and the sleeve panel 3 can be made very small, and at the same time, the gap between the door body 2 and the sleeve panel 3 can be made very small. The support plate part 4b and the gap S interposed between the door body 2 and the panel 3 can be completely hidden by the matching part 5a provided in the door body 2.

Therefore, on the facing surface 24 on the front side of the door,
Since not only the mullion main body 4a but also the supporting plate portion 4b protruding from the mullion main body 4a are not exposed at all, the visibility of the entire door becomes very good.

Furthermore, since the door body 2 and the sleeve panel 3 can be assembled in close proximity, the width of the sleeve panel 3 can be selected to be the same as the width of the child door forming the door body 2 and the double door. It can also be used as a child door. Therefore, the trouble of separately manufacturing the sleeve panel 3 and child door provided in the opening having the same opening area is eliminated.

In addition, as in the embodiment, the door body 2 is attached to the support plate portion 4b.
By attaching a rubber gasket 19 that comes into sliding contact with the prospective surface 18 of the door, the gap S between the door body 2 and the sleeve panel 3 can be
It can block outside air coming in.

Furthermore, if the joining part 5b is formed of a magnetic bead 22 that sticks to the back cover 9 of the door body 2, it is possible to reliably prevent outside air that has passed through the gasket 19 from entering the room.

Furthermore, if the gap S is surrounded by the magnetic bead 22, the mullion main body 4a made of a hollow cross-sectional member, and the heat insulating material 14, the heat insulating effect of the door can be significantly improved.

In the above embodiment, a case has been described in which the support plate portion 4b is provided protrudingly from the mullion main body 4a through the heat insulating material 14, but the mullion 4 according to the present invention is not limited to this, and may be provided as shown in FIG. Alternatively, the heat insulating material 14 may be omitted and the mullion main body 4a and the support plate portion 4b may be integrally extruded from aluminum.

Further, the support plate portion 4b is connected to the prospective surface 6 of the sleeve panel 3.
It is not limited to the case where the parts are fitted along the same line, but may be fastened with screws.

Furthermore, the mullion main body 4a has a magnetic bead 22.
It is also possible to use a door stop that comes into direct contact with the back surface of the door body 2 without attaching it.

[Effect of idea]

As described above, in the mullion according to the present invention, the columnar mullion main body is erected on the back side of the door, and the support plate part protruding from the mullion main body is attached along the expected surface of the sleeve panel. Since the side edges are fixedly supported, the distance between the door body and the sleeve panel is determined by ensuring only the thickness of the support plate that supports the shaft panel and a small gap necessary for opening and closing the door body. This is sufficient, and the door body and sleeve panel can be brought together in close proximity like a double door without a mullion. Therefore, the pillar-shaped mullion body is not exposed on the facing side of the door and does not spoil the appearance, and the overall appearance of the door is improved, which is an excellent effect. The sleeve panel and the child door can be made to have the same width as the width of the child door that can be opened and closed in an opening with the same opening area, so that the sleeve panel and the child door can be used separately. It also has the effect of eliminating the trouble of manufacturing, and is extremely useful.
