Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a door which is installed in an opening provided in a partition wall between rooms or a passage between rooms such as a house, and a method of installing the door.

[0002]

2. Description of the Related Art In order to impart sound insulation performance to a door, a sound insulation material is used for the structure of the door body, that is, the constituent material of the door body, while the door mounted on the door frame and the door stop are hermetically attached. Must be configured to meet. In particular, when the mounting accuracy of the door frame or the door stopper mounted on the door frame is poor, a gap is generated between the door and the door stopper, and the sound insulation is deteriorated. For this reason, it has been customary to use a latch receiving hinge with a function of adjusting the hinge for door-to-door contact or attaching the door to the door frame, even if there is some deviation in the construction. It is possible to correct the poor contact with the hit.

[0003]

However, according to the door-stopping device for cutting the door-contact surface, not only can it be applied to a wood-based material that can be cut, but also the skill of the processing technique is high. In addition, even if the door is warped due to aging even if it is processed accurately, a gap will be created between the door and the door stop, resulting in poor adhesion. There was a problem that the function as a soundproof door was impaired even if the packing was provided around it.

On the other hand, when a latch receiving hinge having an adjusting function is used, even if the door warps due to a change with time, the degree of close contact of the door with respect to the door contact can be finely adjusted. Since the adjustment range is small, there are cases where sufficient adhesion cannot be obtained even if the adjustment is performed. Further, in any case, the door or the door stop is displaced in the width direction of the door frame when the door is attached to the door frame provided with the door stop or when the door stop is attached to the door frame after the door is attached. If the door is mounted in a position, not only the door and the door stop cannot accurately contact each other in a surface contact state, but also there is a problem that a smooth opening / closing operation of the door cannot be performed.

That is, when the door stop is attached to the front of the door frame in the opening / closing direction of the door,
Not only does the door come into line contact with the corner of the door, but when the door is rotated from the open state to the closing direction, the door close to the door mounting position before the door closes. The pivoting side part of the door comes into contact with the contact part, that is, the door stop attached to the upper and lower door frame parts first, and even if packing is provided in the door stop, the packing of that part is strongly pressed and the door is pressed. Repress in the direction to open the
Door closing operation becomes heavy.

Further, when the door stop is attached to the door frame at a rearward position retracted in the opening / closing direction of the door,
The door tip will come into line contact with the inner corner of the door stop, and the swing angle of the door to that point will increase, resulting in excessive stress on the hinges for a lighter opening and closing operation. And the door stop attached to the upper and lower door frame parts gradually separates from the front end side of the door toward the pivot side, and a gap is created, which significantly reduces the sound insulation function. Dots occur. Further, if the door stop is attached in a state in which the length direction thereof is slightly inclined with respect to the width direction of the door frame, the door and the door stop are in a partial contact state, and airtightness and sound insulation are impaired. It will be.

The present invention has been made in view of the above problems, and has a door structure in which the mounting position of a door stop with respect to a door frame is adjustable to exhibit excellent airtightness and sound insulation, and a method for mounting the door. The purpose is to provide.

Then, the rear surface protrusion of the door stop is moved in the groove width direction in the recess groove of the door stop mounting frame portion to correct the inclination of the door stop in the length direction with respect to the contact surface with the door and to improve the parallelism. After adjusting the position so that the two are in surface contact over the entire length, the door stop is fixed.

At this time, as described in claim 2,
If the door stop is made hollow, the front side is a lid that can be opened and closed, and the projecting ridge has a long screw mounting long hole in the width direction, the door and door stop will contact. While looking directly at the state, adjust the door stop to the proper position by moving the door stop in the groove width direction along the long hole with respect to the screw temporarily fixed in the groove, and screw the screw with the lid open. Thus, the door stop can be easily fixed at an accurate position, and after the fixing work, the lid head is closed to conceal the screw head, thereby providing a good appearance. At this time, as described in claim 3, if the lid body is formed separately from the back surface side, the lid body does not get in the way and the door work can be smoothly attached, and the work can be performed smoothly. Efficiency improves.

By providing the packing at the door abutting portion of the door stop as described in claim 4, it is possible to obtain a door structure exhibiting better airtightness and sound insulation, and As described in Item 5, if a sealing material is provided on at least one of the groove bottom surface of the recessed groove of the door frame portion and the back surface of the door stop, the recessed groove provided in the door stop mounting frame portion or Even if there are variations in the dimensional accuracy and processing accuracy of the ridges on the door stop, the variations can be absorbed and accurate construction can be performed.

Also, after the door is installed, even if the door warps or twists due to aging, loosen the screws to move the door stop in the groove width direction in the recess groove of the door stop mounting frame portion. Thus, similarly to the above, the door stop can be position-adjusted and fixed to the accurate contact position with respect to the door.
