[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an opening device provided with, for example, a steel door frame.
[0002]
[Prior art]
Conventionally, the entrance door of each apartment, such as a condominium, is constructed by incorporating a door into a steel frame body, and since the frame body is an exterior product, the factory shipment is basically performed with each part of the frame body joined by frame welding. It was. However, this type of product has poor transport efficiency due to shipment of the finished product, and after welding, the finished state varies depending on the worker due to the sander finish, and the appearance is not stable, and the watertightness decreases depending on the welding method. There was a problem such as. In order to solve these problems, an assembly-type steel door sash frame has been proposed (for example, Japanese Patent Publication No. 59-19235).
[0003]
[Problems to be solved by the invention]
However, according to the conventional configuration, there is a problem with water tightness at each joint portion of the frame body. When a water tight member is used at each joint portion in order to increase the water tightness, the water tight member is the outdoor side surface portion. However, the design property is inferior, and the watertight member protrudes, so that there is a problem that the finished feeling of the outer surface coating is lacking.
[0004]
Accordingly, an object of the present invention is to provide an opening device capable of improving water tightness and improving designability in order to solve the above-described problems.
[0005]
[Means for Solving the Problems]
The invention according to claim 1 is configured by incorporating a door, a sash shoji, and the like into a frame, and the frame includes an upper frame, a lower frame, and a vertical frame, and the upper frame or the lower frame is attached to the vertical frame. The longitudinal frame against which the end portion is abutted is notched leaving the outdoor side surface portion, and a joining member is joined to the notched portion to form a joined portion. Is retracted with respect to the upper frame or the lower frame, and the retracted joint portion and the outdoor side surface portion form a watertight member accommodating portion, and the watertight member is accommodated in the accommodating portion and the frames Are joined by a fixing tool.
[0007]
According to this invention, since the watertight member is accommodated in the accommodating portion and the frames are joined together by the fixing tool, the watertightness can be improved, and the end of the other frame is abutted against one frame. The joint portion of at least one frame is made to recede with respect to the other frame, leaving the outdoor side surface portion, so that the outdoor side surface portion is flush with the presence of the outdoor side surface portion. Easy to paint.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
[0009]
In FIG. 1, the code | symbol 1 has shown the steel-made frame which comprises the entrance door, for example. A door 5 such as a door or a sash shoji is attached to the frame 1 through a plurality of hinges 3 so as to be freely opened and closed. The door body 5 is opened and closed in the direction of the arrow Y with respect to the suspension base TM. Reference numeral 7 denotes a knob.
[0010]
The frame body 1 includes an upper frame 11, a lower frame 13, and vertical frames 15 and 17, and in this embodiment, each frame 11, 13, 15, and 17 is an assembly type.
[0011]
If it demonstrates about the junction part A of the suspension side TM, it will assemble as shown in FIG. 2, FIG. That is, a joining member 23 having a female screw hole 21 is fitted to the opening end of the upper frame 11 at the right end in the drawing so as to be flush with the opening end, and is joined to the inside of the opening end by welding. On the other hand, the upper end surface of the vertical frame 15 against which the upper frame 11 is abutted is notched leaving the outdoor side surface portion 15a protruding toward the upper frame 11 and the upper end surface of the vertical frame 15 against which the upper frame 11 is abutted. A joining member 27 having a hole 25 is joined to the back surface of the, and a joining portion 31 to the upper frame 11 is formed there.
[0012]
The joint portion 31 is retracted with respect to the upper frame 11, and the housing portion 35 of a watertight member 33 made of, for example, a caulking sealer is formed by the retracted joint portion 31 and the outdoor side surface portion 15a. A watertight member 33 is accommodated in the accommodating portion 35, and the watertight member 33 is bonded to the joining member 27 by using, for example, a double-sided adhesive tape. After that, the frames 11 and 15 use tools such as a screwdriver. Used, for example, by a fixing tool 37 made of screws or the like. In addition, although illustration was abbreviate | omitted, the remaining three junction parts BD of the frame 1 are joined by the same structure.
[0013]
In this embodiment, when the upper end surface of the vertical frame 15 is notched, it is important to leave the outdoor side surface portion 15a protruding toward the upper frame 11 side. This is because when the frames 11 and 15 are joined together by leaving the outdoor side surface portion 15a, the watertight member 33 does not protrude outside the outdoor side, and the watertight member 33 can be covered.
[0014]
The extent to which the outdoor side surface portion 15a protrudes to the upper frame 11 side varies depending on the thickness of the watertight member 33. In this embodiment, since the thickness of the watertight member 33 is about 0.5 mm, when considering the compression allowance of the watertight member 33, the thickness of the watertight member 33 can be projected to the upper frame 11 side by about 0.4 mm. That's fine. If this protruding dimension is too large, when the upper frame 11 and the vertical frame 15 are brought into contact with each other and the frames 11 and 15 are joined together, the watertight member 33 is not crimped and the watertightness is lowered. There is a gap between 11 and 15, and the watertight member 33 is exposed outside the room. In this embodiment, by using the joining member 27, it is only necessary to manage the protrusion amount of the outdoor side surface portion 15a based on the surface of the joining member 27. Therefore, the projecting dimension can be easily managed almost accurately. it can.
[0015]
According to this embodiment, since the watertight member 33 is accommodated in the accommodating portion 35 and the frames 11 and 15 are joined together by the fixing tool 37, the watertightness can be improved, and the entrance door of each house such as an apartment can be used. Is preferred. The frame is packaged and shipped from the factory in a separate state and assembled on site. Therefore, compared with the conventional one, the transportation efficiency is improved, and the sanding finish after welding is not required, so that various effects such as improvement in appearance stability can be obtained.
[0016]
Moreover, in this embodiment, since the joining part 31 of the vertical frame 15 is made to recede with respect to the upper frame 11 leaving the outdoor side surface part 15a, the upper frame 11 in the outdoor side surface part 15a by the presence of the outdoor side surface part 15a. Since the vertical frame 15 is flush with the vertical frame 15, the outer surface of the frame 1 can be easily painted. Usually, the frame 1 is fitted into the entrance of a condominium or the like without being painted, and is finished when the interior construction of the apartment is completed. According to this, since the watertight member 33 does not protrude to the outdoor side and is covered and hidden by the outdoor side surface portion 15a, the design can be improved.
[0017]
As mentioned above, although this invention was demonstrated based on one Embodiment, it is clear that this invention is not limited to this. For example, in the above-described embodiment, the joining portion 31 is formed using the joining member 27. However, in order to reduce the number of parts, it is possible to form the joining portion by denting the upper end surface of the vertical frame 15 by pressing.
[0018]
【The invention's effect】
According to the first aspect of the present invention, since the watertight member is accommodated in the accommodating portion and the frames are joined by the fixing tool, the watertightness can be improved, and the upper frame or the lower frame is attached to the vertical frame. end and abutting by joining, with the devoted vertical frame ends butt cutting away leaving the outdoor side unit, a joint portion formed by joining the joining member to the notched portion, this bonding portion, since retracted relative to the upper frame or the lower frame can accommodate watertight member accommodating portion, not visible watertight member from the outside, it is possible to improve the design property, further, outdoor Management of the protruding dimension of the side surface is simplified.
