DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of hinged doors provided at openings of buildings such as houses, condominiums and buildings.

[0002]

2. Description of the Related Art Today, some hinged doors, such as hinges and pivot hinges, whose shaft support members are exposed to the outside, impair the appearance of the door. There is known an apparatus in which a pivot member for opening and closing is interposed between upper and lower door frames facing the above so as to prevent the shaft support member from being exposed. In this case, the state in which the door body is swung by approximately 90 degrees from the fully closed position may be set to the fully open position. In such a case, when opening the door body, the door body may be vigorously opened, and in order to prevent the door body from turning too much in such a case, as shown in FIG. Door frame 26 in the fully open position
And an extension 25a which is parallel to the extension 25a.
The door body 26 that is going to be opened beyond the fully open position hits the door body 26 to prevent the door body 26 from rotating.

[0003]

However, in this case, the vertical door frame 25 must be configured so that the extension 25a protrudes to the outdoor side, so that the door body 26 is located on the indoor side correspondingly. As a result, there is a problem that the interior space must be narrowed and the habitability is impaired, and there is a problem to be solved by the present invention. Furthermore, in the conventional hinged door, from the viewpoint of consideration for finger stuffing, as shown in FIG. 8, the door stop 27a of the hanging side vertical door frame 27 is made to have a small protrusion amount to substantially the pivotal support position,
It is proposed to avoid finger jamming by providing an airtight material 28 at the tip of the short door stop 27a. In this case, however, the resilient sliding relationship between the airtight material 28 and the hanging end surface 29a of the door body 29 is performed through the entire opening and closing process of the door body 29. As a result, finger tightness can be avoided. 28
Is not allowed to wear out early, but there is an error in the clearance between the airtight material and the door at the time of construction, and the airtightness is impaired due to too much clearance, or conversely There is a problem that the opening and closing operation of the door body becomes heavy because the material and the door body are too close. On the other hand, as shown in FIG. 7, the door body 26 is
The thickness of the flat surface portion 26b is made larger than the diameter of the flat surface portion 26b, and the step surface portion 26c is formed between the curved surface portion 26a and the flat surface portion 26b.
It is conceivable to prevent wear of the airtight material 30 as a configuration in which the hanging side end of the flat plate surface portion 26b that is thickened like a step only comes into contact with the airtight material 30 only when fully closed. In this case, in the process of closing the door body 26, a small gap is formed between the curved surface portion 26a and the tip of the door stop 25b by the thickness of the stepped surface portion 26c. When the finger enters, the finger may be pulled into the inner side of the vertical door frame 25 by the step surface portion 26c just before closing, and may be in a finger-packed state,
Each of them has a problem, and there is also a problem to be solved by the present invention.

[0004]

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention has been made to solve these problems, and has been developed to solve the above problems.

By doing so, the stopper surface portion is formed on the door stop surface, and the expected size of the door frame can be reduced. In this case, the stopper surface portion on the vertical door frame side of the present invention is formed integrally with an airtight material for ensuring airtightness by contacting the end of the door body hanging side when the door is fully closed. can do. Further, in this case, in addition to the stopper surface portion, the hanging end side end surface of the door body of the present invention abuts on the airtight material from the inside in the width direction of the frontage at a position immediately before the door body is fully closed, and the airtight material is removed. The contact surface portion for elastically deforming outward in the width direction of the frontage in the fully closed posture of the door body may be formed. Further, in this case, an intermediate surface portion set to be separated from the airtight material in a halfway open posture is formed between the stopper surface portion and the contact surface portion on the hanging end side end surface portion of the door body of the present invention. Things.
Still further, in this case, the suspension body side end surface portion of the door body has an intermediate surface portion set between the stopper surface portion and the contact surface portion so as to abut on the substantially natural airtight material in the halfway open position of the door body. Is formed. In this case, the pivot interposed in the door of the present invention may be eccentric with respect to the center of the thickness of the door.

[0005]

Next, an embodiment of the present invention will be described with reference to the drawings. First, the first embodiment is shown in FIGS.
As shown in FIG. 4, in the drawing, reference numeral 1 denotes a hinged door built at the opening of the skeleton, and a door 2 constituting the hinged door 1
On one side of the upper and lower end surfaces (on the hanging side and on the right side in FIG. 1), bearing recesses 2a and 2b are respectively provided. On the other hand, upper and lower door frames 3 and 4 and left and right door frames (vertical door frames) 5 and 6 are fixed to the opening of the skeleton, but project from the upper and lower door frames 3 and 4 toward the inside of the opening. Swing axis 3
The door body 2 is opened and closed with respect to each of the door frames 3, 4, 5, and 6 by swingably and internally fitting and supporting the bearing recesses 2a and 2b on the door body 2 side. It swings from the fully closed position to close the opening to the outside (in the direction of arrow A) to the open position to open the opening, and these configurations are all conventional.

[0006] A contact surface portion 2c formed by bending the door body 2 at a right angle from the indoor side surface is provided on an end surface on the hanging side.
A stopper surface portion 2d formed by being bent at a right angle from an outdoor side surface protruding outwardly in the frontage direction (frontage width direction) than the contact surface portion 2c, and the contact surface portion 2c and the stopper surface portion 2d. And an intermediate surface portion 2e formed in a curved shape and located therebetween. Furthermore, the center O of the concave portions of the bearing concave portions 2a and 2b (corresponding to the center of the pivot of the present invention) O formed at the end of the hanging body side is the thickness center line L The position is slightly eccentric to the outdoor side, and the position in the frontage direction is a distance of approximately 1/2 of the door body plate thickness from the stopper surface portion 2d. It is set to coincide with the formation position of 2c.

On the other hand, of the left and right door frames 5 and 6, the right hanging side door frame 6 has a door stop surface 6 a facing the indoor side surface of the door body 2 and a hanging side end surface of the door body 2. Inner surface 6b facing
Are formed in a substantially L-shape. The front end of the door stop surface 6a extends to a position substantially opposite to the hanging side end of the indoor side surface of the door body 2 in the fully closed state. It is fixed over the whole direction. Here, the airtight material 7 is formed of a rubbery elastic material and is elastically deformed. The airtight material 7 of the present embodiment has an indoor side surface of the door body 2 having a front end surface (outside end surface) 7a in a fully closed position. It is provided with a dimension setting protruding to a position slightly beyond the position. The hermetic member 7 measures the airtightness between the door body 2 and the hanging side door frame 6 by abutting on the contact surface 2c of the door body 2 in the fully closed posture of the door body 2. However, in this state, the positional relationship between the contact surface portion 2c and the airtight material 7 is such that the door body contact surface portion 2c is pressed by the airtight material 7 and the front end portion 7a side of the airtight material 7 has a front end inner end portion 7b. Are set to elastically deform. Further, in the state where the door body 2 is in the fully open position, the swing center (recess center O) of the door body 2 is eccentric to the outdoor side. The stopper surface 2d is set so as to just contact the airtight material front end surface 7a in the natural state.
Is set so that the stopper surface portion 2d is prevented from rotating by the airtight material front end surface 7a, and further opening swing is restricted. Thereby, the airtight material 7 is set so that the front end 7a functions as a stopper surface for the door body 2 and the front end 7b functions as an airtight surface.

In the middle state of the door 2 swinging from the fully opened position with the center O of the concave portion as the axis, the door body intermediate surface 2e faces the airtight material front end surface 7a. Since 2e is a curved surface extending from the stopper surface portion 2d that just contacts the airtight material 7 to the abutting surface portion 2c retracted inward in the frontage direction, the intermediate surface portion 2e is set so as not to come into contact with the airtight material 7. Have been. The door body 2 comes into contact with the front end 7b of the airtight member 7 from the front side at the position immediately before the door body 2 is completely closed from this halfway open position, and the door body 2 is brought into contact with the front end. With the fully closed position,
As described above, the contact surface portion 2c is set so as to press the airtight material inner end portion 7b to be elastically deformed.

Incidentally, the end surface of the hanging side of the door body 2 is constructed as follows. In other words, the suspension-side edge member 8 of the door body 2 is formed with three-step prospect surfaces 8c, 8d, and 8e by forming two-step surfaces 8a and 8b. Then, the edge of the indoor-side surface plate 9 is bent from the first-stage expected surface 8c to the first-stage step surface 8a, and the outdoor-side surface plate 10 is bent.
Is bent along the third-stage expected surface 8e. When the door body 2 opens and closes, both end edges of the intermediate surface portion 2e are overlapped with the end portions of the surface plates 9 and 10 in order to reduce a gap facing the airtight material 7 in the process of opening and closing. Then, the door body 2 is fixed to the edge member 8 by a stopper member 11 such as a rivet, thereby forming a hanging side end surface of the door body 2.

[0010] In the embodiment of the present invention configured as described above, the door body 2 has the bearing recesses 2 recessed in the upper and lower end surfaces.
a swing support shaft 3 protruding from the upper and lower door frames 3 and 4 on a and 2b
a, 4a are fitted and supported by being pivoted, thereby opening and closing the opening part. In this case,
The air-tight member 7 for air-tightness between the door body 2 and the hanging side door frame 6 has its front end surface 7a serving as a stopper surface, and just abuts against the stopper surface portion 2d of the door body 2 in the fully opened posture. It is arranged in. As a result, the airtight material tip surface 7a is
Will function as a detent member for avoiding the open swing exceeding the fully open position of the first position. Therefore, unlike the conventional one, there is no need to form an extension portion extending to the outdoor side on the vertical door frame to measure the rotation of the door body, and to reduce the expected size of the door frame 6 to reduce the indoor space. There is no loss.

In this case, one airtight material 7 is
When the door body 2 is fully closed, the front end 7a of the door body 2 abuts against the door body contact surface 2c in a resilient manner to function to secure airtightness with the door body 2. In the fully opened state, the tip 7b functions as a stopper surface to function as a stopper for the door body stopper surface 2d to fulfill the function of preventing the door body 2 from rotating, so that the members can be shared.

Further, in this case, the door body 2 and the airtight material 7 come into contact only when the door body 2 is fully closed and fully opened, and do not come into contact when the door body 2 is halfway open, thereby reducing abrasion of the airtight material 7. In this case, the door body contact surface portion 2c is formed in a stepped shape on the hanging side end surface of the door body 2 while the contact surface portion 2c and the airtight material 7 The contact is made at the front end of the airtight material 7 on the outdoor side, and since the contact surface 2c comes into contact with the airtight material 7 from the inside in the width direction of the frontage, the finger is drawn into the door frame 6 by the contact surface 2c. Even so, the finger is protected by the airtight material 7.
