Description

Hinge structure for revolving door {HINGE STRUCTURE FOR HINGED DOOR}

The present invention relates to a revolving door hinge, and more specifically, to a revolving door hinge structure in which horizontal adjustment of a sliding door such as an entrance door is made simple.

In general, the door of a building or office has a hinged door or a swing door, which is a common type of door, and the door can be opened and closed by providing a hinge or a hinge at the upper and lower parts to open and close the door. is to make it In the case of such a hinged door, a leveling operation may be performed in the process of coupling one of the upper and lower parts during installation and coupling and fixing the other one. In the case of a door having a large weight, the process of fixing the door to the frame is performed by manpower, and there is a problem that it is very inefficient. On the other hand, the opening degree of the fixed opening/closing type door is generally 180 degrees, and in some cases, it is only about 90 degrees when it is coupled through a hinge. This may cause inconvenience to users using the door due to the narrow opening angle.

Therefore, there is a need for a door opening capable of solving the above-mentioned problems, and a structure in which more improved work efficiency can be expected in the construction process of combining the door is required.

The section can be narrowed as much as the spaced distance within the maximum by narrowing, and in this case, the door 1 can have a structure in which the door frame 3 and the door frame 3 are maximally spaced apart. Conversely, as the section is widened, it may be narrowed by the minimum spaced distance, and in this case, the door 1 may have a structure in which the door frame 3 and the door frame 3 are minimally spaced apart. Here, the section may be determined by adjustment of the adjustment pin 125a, and the adjustment pin 125a may be adjusted as illustrated in FIG. 6 below.

6 is a view showing that the adjusting unit 120 is coupled to the base unit 110 according to an embodiment of the present invention.

Referring to FIG. 6 , the adjustment unit 120 is seated on the body seating unit 112a and has a long hole 124 into which the guide bar 113 is inserted and a rotation hole 123 into which the first rotation shaft 101b is inserted. It includes a locking block 125 that is seated on the main body 121 and the block seating portion 112b. Here, the main body 121 and the locking block 125 may be connected to each other through an adjustment pin 125a so that the separation distance from each other can be adjusted.

In addition, the area of the body seating portion 112a is formed to be wider than the seating surface (the body seating portion 112a) of the main body 121 , and at least a spare area in the direction in which the long hole 124 extends may be secured. One end of the adjustment pin 125a is exposed so that it can be manipulated, passes through the locking block 125 from the one end through screw thread coupling, and the other end can be connected to the main body 121 so that it can rotate freely. When the adjustment pin 125a is drawn in or drawn out with respect to the locking block by the free rotation, the rotational force is not transmitted to the main body 121, but only the pressing force can be transmitted in the incoming or outgoing direction.

Specifically, referring to FIG. 6(c) , the adjustment pin 125a may be freely rotated within the rotation hole 128 provided in the protruding body 122 . Specifically, a pressure plate 129 having a diameter expanded from the adjustment pin 125a is formed in the rotation hole 128 and the pressure plate 129 can be rotated by the rotation of the adjustment pin 125a. Here, the pressure plate 129 can be pressed in the retracting direction when the adjusting pin 125a is in contact with the main body 121 at the time of the retraction, so that the main body 121 is moved by pressure on the body seating portion 112a. can Of course, the movement of the main body 121 means moving along the extension direction of the long hole (124).

Conversely, the pressure plate 129 can check the adjustment pin 125a in the withdrawal direction in a state of contact with the main body 121 during the withdrawal, so that the main body 121 is checked on the body seating part 112a. It can be moved in the withdrawal direction. Of course, the movement of the main body 121 means moving along the extension direction of the long hole (124).

Even when the door frame 3 is tilted at a predetermined angle by the pressing force, the door 1 can be kept level by compensating for the tilted angle. Here, the state of the adjustment unit 120 that implements the maximum angular range that can be compensated is shown in FIGS. 6(a) and 6(b), which are shown in FIGS. 7(a) and 7(b) below. The angle of the door frame 3 may be implemented.

7 is a view showing the side of the rotating door coupled to the forward and retracted state of the adjustment unit 120 according to an embodiment of the present invention.

Referring to FIG. 7 , as described above, the separation distance is adjusted within the range of the extended section of the long hole 124 with respect to the guide bar 113 by the adjustment of the adjusting pin 125a, whereby the first rotational shaft 101b) An angle formed between a coaxial axis formed by the second rotation axis 212 and a vertical axis may be varied. The variable angle can be compensated for as much as the angle of the inclined door frame 3 .

That is, it can be tilted to the left with respect to the door frame 3 to form a first angle A1 as shown in FIG. The second angle A2 may be formed together. Even when inclination of the door frame 3 occurs through the change of the angle, the door 1 connected to the first assembly 100 and the second assembly 200 may be aligned in vertical and horizontal directions. Of course, this means that it is possible when the inclination of the door frame 3 occurs within the angular range adjustable by the adjustment unit 120 .

8 is an exploded perspective view showing the first assembly 100a and the second assembly 200a according to another embodiment of the present invention.

Referring to FIG. 8( a ), in an embodiment except for the first door bracket 101 from the above-described first assembly 100 , the first rotation shaft 101b may be directly connected to the door 1 . This may be a connection through simple insertion, or may be a permanent fixed coupling. This is not limited as a matter that can be selectively determined according to construction conditions such as the material and weight of the door 1 by those skilled in the art.

In this example, since the first door bracket 101 is not included, it may not be fixedly coupled to the door 1 through means such as fasteners. Of course, in order to secure the rotation angle R, it is preferable to be spaced apart so that interference does not occur during rotation between the width of the door 1 and the door frame 3 even in this case.

Referring to FIG. 8( b ), the second rotation shaft 212 is located on the same axis as the first rotation shaft 101b to promote the rotation of the door 1 , and is formed from the second assembly 200a. In an embodiment except for the two door bracket 201 , the second rotation shaft 212 may be directly connected to the door 1 . This may be a connection through simple insertion, or may be a permanent fixed coupling. This is not limited as a matter that can be selectively determined according to construction conditions such as the material and weight of the door 1 by those skilled in the art. In addition, since the second door bracket 201 is not included for the same purpose as the first assembly 100a, it may not be fixedly coupled to the door 1 through means such as fasteners.

As described above, in the detailed description of the present invention, the most preferred embodiment of the present invention has been described, but various modifications are possible without departing from the technical scope of the present invention. It is not limited to the example, but the scope of protection should be recognized from the techniques of the claims to be described later and equivalent technical means from these techniques.
