The present invention relates to a door and a door frame, and more particularly, to a door that is opened and closed by a rotational movement around a fixed axis and a door frame in which the door is installed.

In general, the door is installed on the door frame using a hinge. For example, when installing the door frame and the door in the front porch of the house, the door is installed on the door frame by first fixing the door frame to the wall, then fixing one side of the hinge to the door frame and the other side to the door. However, it is difficult to install and difficult to level, and because the hinge protrudes to the outside, not only the appearance is not good, but the center of gravity of the door is not in the door, there is a problem inclined to one side.

As a technique for improving the above problems, a technique for fixing the shaft to the upper and lower portions of the door without using a hinge is disclosed in the Utility Model Registration No. 20-149147 filed by the present applicant and the Utility Model Registration No. Introduced in 20-223101, "Pivot Hinges for Entrance Doors." However, some problems arise when fixing the door by the shaft.

FIG. 1A is a diagram illustrating a main part of a query according to an example of the related art, and FIG. 1B is an operation state diagram of FIG. 1A.

Referring to FIGS. 1A and 1B, when the wall 590 and the door 510 are placed in a straight line and a fixed shaft 555 that is a rotation axis of the door 550 is installed within the thickness of the door 510, the door The fixed shaft 555 for fixing 510 is structurally stable because it is at the center of gravity of the door 510. However, a predetermined distance d is required between the door 510 and the wall 590 (or the door frame) so that the corner portion A of the door 510 does not hit the wall 590 when the door 510 is opened or closed. In other words, a distance d is required between the door 510 and the wall 530 so that the wall 590 is located outside the circular trajectory whose radius r from the center O of the fixed shaft 555 to the door edge A is a radius. As a result, a gap is formed between the door 510 and the wall 590, and therefore, it is not suitable as a security door or a fire door and the appearance is not beautiful. Also, as shown in FIG. 1B, since the door 510 is caught by the wall 590, the opening and closing angle of the door 510 is not large. In order to increase the opening and closing angle of the door 510, the distance between the door 510 and the wall 590 should be further increased.

FIG. 2A is a diagram illustrating a main part of a query according to another example of the related art, and FIG. 2B is an operational state diagram of FIG. 2A.

2A and 2B, when the pivot hinge 620 including the fixed shaft 655 is installed at the top of the door 610 at a position separated by a predetermined distance to the front or the rear of the wall 690, the door It is not necessary to consider contact with the wall 650 because the fixed shaft 655 provided as the rotating shaft when opening and closing 610 is not present on the rotational trajectory of the door 610. Thus, the door 610 may be in close contact with the wall 690. However, since the fixed shaft 655 to which the door 610 is fixed is installed at a distance away from the center of gravity of the door 610, the load received by the door 610 is large. Therefore, the inclination of the door 610 may be generated when used for a long time, and the wear of parts including the fixed shaft 655 proceeds quickly. Moreover, even after the door 610 is closed, there is a difficulty in using as a fire door or a security door because the part in which the door 610 is fixed in the pivot hinge 620 is outside the door, and the appearance is not beautiful.

Therefore, the object of the present invention is to provide a door that is structurally stable and aesthetically superior door and the door frame is installed so that the gap between the door and the door frame to the maximum and the fixed axis of the door exists within the center of gravity of the door.

In order to achieve the above object, the present invention is a door having a size and shape accommodated in the door frame and the door frame fixed to the wall,

A door having a fixed shaft that is perpendicular to each other on one side edge of the upper inner surface and the lower inner surface of the door frame and installed on the door frame, and having a size and shape accommodated inside the door frame; And shaft fitting holes having shaft fitting grooves installed on the upper and lower surfaces of the door at positions corresponding to the shaft fixing parts, respectively, to which the fixing shaft is fitted.

A groove is formed on the inner side of the inner side close to the fixing shaft to avoid the side trajectory of the door close to the center of the fixing shaft, and the door connects the upper and lower fixing shafts at the position corresponding to the inner side edge portion of the door frame on the front of the door. The front groove is formed to a predetermined depth in parallel with the virtual rotary shaft, and the shaft fitting groove of the shaft fitting hole provides a door positioned between the front groove of the door and a side close to the fixed shaft, and a door frame on which the door is installed.

In the door according to the present invention and the door frame in which the door is installed, the shaft fixture is preferably installed such that the shaft fitting ring is formed on the front side edge portion of the door while being close to the side of the door. And the shape of the groove formed in the door frame may be a "c" shape including an inclined surface inclined from the side edge of the door frame.

Hereinafter, embodiments of the door and the door frame according to the present invention will be described in detail with reference to the accompanying drawings.

Example

Figure 3 is a front view showing a door and a door frame according to an embodiment of the present invention, Figure 4 is a partially assembled perspective view of the door and the door frame according to an embodiment of the present invention.

3 and 4, the door 10 and the door frame 30 according to the present embodiment have the door 10 fixed to the door frame 30 by the fixed shaft 55 and the fixed shaft 55 as the rotating shaft. As a structure that is opened and closed by a rotational movement, the door 10 and the door frame 30 are installed in close contact with each other, and the side rotation trajectory of the door 10 is formed on the inner side of the door frame 30 facing the side of the door 10. Avoid the groove 33 is formed, the front surface of the door 10 is characterized in that the front groove 13 is formed in which the corner portion of the door frame 30 is accommodated in a certain portion.

In more detail, the door 10 is in the form of a square plate having a predetermined thickness and the door frame 30 is in the form of a square frame having an inner space in which the door 10 is accommodated. The door frame 30 is fixed to a wall (90 of FIG. 5) to which the door 10 is to be installed. And, the door frame 30 may have a step to limit the rotational movement of the door 10 and to guide the closed position so that the door frame 30 can be opened only in one direction. The door 10 and the door frame 30 may be made of various materials in a range where a certain level of strength is secured. For example, it may be made of iron or aluminum. In addition, the door 10 and the door frame 30 may be manufactured by bending and joining a plurality of metal plates. For example, the door 10 can be made by bending an iron plate or an aluminum plate and joining by welding.

Shaft fixtures 50 are installed at one side edge portion of the upper and lower surfaces of the door frame 10. The shaft fasteners 50 are fixed to the door frame 30 with fastening members, such as screws 81. The shaft fasteners 50 each have a fixed shaft 55. The fixed shaft 55 penetrates the door frame 30 to protrude inward. Fixing shafts 55 of the upper and lower portions of the door frame 30 are installed at positions facing each other and provided as a rotation axis of the door 10 within the thickness of the door 10. In the case of the upper shaft fastener 50, the protrusion and the rise of the fixing shaft 55 from the door frame 30 is configured by the raising and lowering of the fixing clamp 53. Thereby, the fastening and separation with the shaft fitting hole 70 to be described later can be easily made.

Shaft fittings 70 are installed at one edge portion of the upper and lower surfaces of the door 10, respectively. The shaft fitting 70 is fixed to the door 10 with a fastening member, for example a bolt 83. The shaft fitting holes 70 have a position adjusting fastening plate 73 having a shaft fitting ring 75 into which the fixing shaft 55 is inserted, and a fixing plate 71 fixed to the upper and lower surfaces of the door 10. The position of the shaft fitting groove 76 of the shaft fitting ring 75 can be adjusted by adjusting the position of the position adjusting fastening plate 73 using the hole 74 formed in the position adjusting fastening plate 73. Thereby, the horizontal adjustment of the door 10 is possible.

Here, the shaft fixture 70 is installed in the corner portion near the front side of the door 10 while the shaft fitting ring 75 is close to the side of the door 10, the rotation of the door side according to the rotation of the door 10 It is desirable to minimize the radius. In addition, the fixing plate 71 and the position adjusting fastening plate 73 of the shaft fastener 70 correspond to the front groove 13 of the door 10, and the fixing plate groove 71a and the position adjusting fastening plate are recessed in a predetermined portion. It is preferable to have the groove 73a.

On the other hand, the door 10 has a front groove 13 of the "c" shape formed in the vertical direction on one side edge portion of the front. The front groove 13 is formed in the longitudinal direction of the door 10 in parallel with the virtual rotation axis connecting the upper and lower fixed shaft 55. The front groove 13 of the door 10 is installed such that the shaft fitting groove 76 of the shaft fitting hole 70 is positioned between the side of the door closer to the shaft fitting groove 56.

Here, the front groove 13 of the door 10 is formed at a position corresponding to the inner side edge edge portion of the door frame 30 when the door 10 is rotated. When the door 10 is opened, a portion of the corner of the door frame 30 is accommodated in the front groove 13. The depth of the front groove 13 determines the degree of opening and closing of the door 10. When the depth of the front groove 13 is made deep, the angle which can open and close the door 10 becomes large. Even when the front groove 13 is not formed, the opening and closing angle of about 90 ° is secured due to the groove 33 of the door frame 30 to be described later. The depth of the front groove 13 can be appropriately set within the range in which the open door 10 can be opened and closed sufficiently. The front groove 13 can be formed by bending by press working, punching, or the like. Here, the front groove 13 may have various shapes. The case of the "c" shape is preferable because it is easy to process by a press.

And, the door frame 30 is formed with a groove 33 on the inner side close to the fixed shaft 55 of the inner side to avoid the side trajectory of the door 10 close to the center of the fixed shaft 55. That is, the groove 33 is formed in the longitudinal direction on the inner side of the door frame 30. The groove 33 enables the rotation of the door 10 in a state where the door 10 is installed in close contact. The groove 33 of the door frame 30 can be formed by bending by press working or punching processing similarly to the door 10. Here, the groove 33 is substantially "c" shaped, and is formed to have an inclined surface 33a at the inner side edge portion of the door frame 30.

Figure 5a is a main configuration of the door and the door frame according to an embodiment of the present invention, Figure 5b is an operating state diagram for the door and the door frame of Figure 5a.

Referring to FIG. 5A, the front groove 13 of the door 10 and the groove 33 of the door frame 30 will be described in more detail. Since it is installed at the top and the bottom, the central axis of rotation O 'is provided within the thickness of the door 10. Since it is formed close to the center of gravity of the door 10, the load applied to the door 10 is greatly reduced compared to the case where the fixed shaft 55 is installed on the outside of the door (10).

The side face 10a of the door 10, in particular the corner portion d ', is the farthest from the fixing axis 55. When the door 10 rotates, a rotational trajectory having a radius r 'having a distance between the rotational center axis O' and the corner A 'of the door is formed. The groove 33 of the door frame 30 is formed to be excavated to the outside of the rotation radius r 'so that physical contact with the door 10 does not occur. Therefore, the door 10 and the door frame 30 can be rotated even in a state in which they are installed in close contact.

The opening and closing angle of the door 10 can be greatly increased by receiving the corner portion A 'of the door frame 30 in the front groove 13 of the door 10.

 Referring to FIG. 5B, when the door 10 is opened, the door 10 is rotated about the fixed shaft 55. The corner portion A 'of the door 10 enters the groove 33 of the door frame 30 and the corner portion B' of the door frame 30 enters the front groove 13 of the door 10. The corner portion B 'of the door frame 30 is opened until it is in contact with the bottom surface of the front groove 13 of the door 10.

6 and 7 are main components of the door and the door frame according to another embodiment of the present invention.

The door 110 and the door frame 130 shown in FIG. 6 is an embodiment implemented with an aluminum chassis. Aluminum chassis are manufactured by extrusion molding. Since the groove 133 is formed without a separate press working, it does not have a bent portion. On the other hand, the rubber packing 85 is provided on the inner side surface of the door frame 130. It is shown that by installing the airtight member such as the rubber packing 85, the sound insulation and the inflow of the outside air can be blocked. In addition, the door 210 and the door frame 230 illustrated in FIG. 7 are examples in which the front groove 213 formed in the door 210 and the groove 233 formed in the door frame 230 are formed in a round shape. The grooves 233 formed in the door 10 and the door frame 230 may have various shapes.

On the other hand, the door and the door frame according to the present invention is not limited to the above-described embodiment. Various modifications can be made within the scope without departing from the technical spirit of the present invention will be readily apparent to those skilled in the art.

According to the door according to the present invention and the door frame in which the door is installed, because the fixed shaft for fixing the door is on the center of gravity of the door is structurally stable. Therefore, even if it is used for a long time, the installation state can be maintained without tilting the door to one side. In addition, the possibility of abrasion due to the contact of the door frame and the door and the wear of the shaft fixing members such as the shaft fastener and the shaft fitting are greatly reduced.

And according to the door according to the present invention and the door frame is installed, the fixing member such as the shaft fastener and the shaft fitting for fixing the door is installed inside the door frame, so it is impossible to dismantle the fixing member in the locked state. It is suitable for use as a security door or a fire door because the door frame is closely attached.

Moreover, the exterior is beautiful because the door and the door frame can be in close contact without the fixing member being exposed to the outside.
