Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door support.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, an upper surface 2a of a door body 1a, an upper frame 4a of a doorway frame 3a to which the door body 1a is attached, a lower surface 5a of the door body 1a and a lower frame 6a of the doorway frame 3a (or There is known a support structure for a door body in which a floor surface) is pivotally connected to the floor surface by pivots 7a and 8a, respectively.

The support structure of the door body 1a can obtain a large opening degree unlike the support structure by the hinge, and since the weight of the door body can be directly received by the lower pivot portion, the door body 1a is It has many advantages such as being unable to open and close due to its own weight.

However, in the conventional support structure for the door body, the door body 1a into which the pivots 7a and 8a have been previously inserted is held at a predetermined mounting position on the upper frame 4a and the lower frame 6a of the entrance / exit frame 3a, and a set screw or the like is held. It is fixed by using, or the pivots 7a and 8a are fixed in advance at predetermined mounting positions on the upper frame 4a and the lower frame 6a of the entrance / exit frame 3a,
There is a problem in that it is necessary to fix the door body 1a with a set screw or the like while holding the door body 1a, and it is difficult to mount the door body 1a in an accurate position and the mounting work is not easy. Especially, it is remarkable in the case of a door having a weight made of metal or dense wood.

[0005]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is that it is difficult to mount it at an accurate position and the mounting work is not easy with a conventional support structure for a door body pivotally attached by a pivot. Is.

[0006]

According to the present invention, pivots projectingly supported on either the upper surface of the door body or the lower surface of the upper frame in the doorway frame facing these surfaces are provided on the lower surface of the upper frame or the door body. A door support for fitting the door to the entrance frame by inserting it into an axial hole formed on the upper surface of the door,
A first support member attached to either one of the upper surface of the door body or the lower surface of the upper frame, and the pivotally attached removably attached to the first support member opposite to the attachment surface of the pivot to the first support member. Of the second support member and a set screw for fixing the first support member and the second support member to each other, and the first support member has a locking portion formed at one end thereof. And a screw hole into which the set screw is screwed is formed at the other end, and the second member engages with the locking portion of the first support member at one end. Is formed, and the insertion hole for the set screw is formed at the other end so as to communicate with the screw hole, so that it can be easily attached to an accurate position. The purpose is to provide a support structure for doors that is easy to install. It is formed.

[0007]

The locking portion of the second support member, which is fitted into the shaft hole formed in advance so as to face the lower surface of the upper frame of the doorway frame or the upper surface of the door body, is provided with the pivot portion of the upper frame of the doorway body or the upper frame of the doorway frame. The door body is temporarily fixed to the entrance / exit frame by engaging with the locking portion of the first support member previously attached to the lower surface, and then the set screw is inserted into the screw hole of the first support member through the insertion hole of the second support member. The first supporting member and the second supporting member are screwed to each other and are superposed on each other.

[0008]

Embodiments of the present invention will now be described with reference to the drawings.

FIGS. 1 to 3 show an embodiment of the present invention, in which a door support 1 includes a first support member 5 attached along an upper frame 3 and a lower surface 4 of an entrance / exit frame 2, and a first support member 5 of the first support member 5. A second support member 6 detachably attached to the support member 5
And a set screw 7 for fixing them.

The first support member 5 is formed in an L shape as a whole by a flat plate having substantially the same width as the door body 8 and is orthogonal to a horizontal portion 9 attached along the lower surface 4 of the upper frame 3 in the doorway frame 2. The vertical portion 12 is attached along the outer surface 11 of the vertical frame 10. At the end portion 13 of the horizontal portion 9 on the vertical portion 13 side, there is a locking portion 15 formed by bending a U-shaped punched tongue piece opened to the other end portion 14 into a side surface L shape. And a screw hole 16 for screwing the set screw 7 is formed in the other end portion 14.

The second supporting member 6 has a plate shape having the same width as the horizontal portion 9 of the first supporting member 5 and a slightly shorter length, and the one end 17 has a locking portion of the first supporting member 5. A locking portion 18 for engaging with 15 is formed and the other end portion 19 is formed.
An insertion hole 20 for the set screw 7 that communicates with the screw hole 16 when engaged with the locking portion 15 of the first support member 5 is formed therein.

The locking portion 18 is formed by bending a tongue piece formed by two notches formed along the edge of the end portion 17 of the second support member 6 upward to a side face L shape.

Further, a pivot 24 which can be fitted into a shaft hole 23 formed in the upper surface 22 of the door 8 is provided on the lower surface 21 of the second support member 6 so as to project therefrom.

In such an embodiment, first, the first support member 5 is attached to the vertical frame by using the set screw 25 so that the horizontal portion 9 of the first support member 5 extends along the lower surface 4 of the upper frame 3 in the entrance / exit frame 2. Then, the door body 8 is in a state (not shown) in which the pivot projectingly provided on the lower surface is fitted and inserted into the shaft hole formed in the lower frame of the entrance / exit frame 2.
The engaging portion 18 of the second support member 6 in which the pivot 24 is fitted in the shaft hole 23 formed to face the upper surface 22 of the first support member 5
The door body 8 is inserted into the locking portion 15 of the
Is temporarily fixed to the doorway frame 2.

Next, with the door 8 open, the insertion hole 20 of the second support member 6 is exposed, and the set screw 7 is inserted into the insertion hole 20.
The first support member 5 and the second support member 6 are superposed on each other by screwing them into the screw holes 16 through the door body 8 to pivotally attach the door body 8 to the doorway frame 2.

Therefore, in this embodiment, the door body 8 can be pivotally attached to the doorway frame 2 by screwing the set screw 7 while the door body 8 is temporarily fixed to the doorway frame 2. It is not necessary to fix the door body by using a set screw while holding the door body like a supporting body for the door body, and the attachment work is easy even in the case of a heavy door body.

In the above embodiment, the pivot 24 is projected on the lower surface 4 of the upper frame 3 of the entrance / exit frame 2, and the shaft hole 23 into which the pivot 24 is fitted is opposed to the upper surface 22 of the door body 8 which faces the pivot 24. Although the case where the pivot 24 is formed is shown, the same applies to the case where the pivot 24 is projectingly provided on the upper surface 22 of the door body 8 and the shaft hole 23 for inserting the pivot 24 is formed in the upper frame 3 of the entrance / exit frame 2 which is the opposite surface. Can be carried out.

[0018]

According to the present invention, the door body can be pivotally attached to the doorway frame by screwing a set screw in a state where the door body is temporarily fixed to the doorway frame. It is not necessary to fix the door body by using a set screw while holding the door body like a support tool, and the attachment work is easy even in the case of a heavy door body.
