The present invention relates to a steel front door of an apartment capable of variable gap filling.

The front door of each generation of apartments is made of steel, which prohibits unauthorized outsiders from entering and increases durability against damage. However, such steel is difficult to fill the space between the door frame and the door itself made of steel because the surface strength is relatively large and the flexibility and cushioning function is relatively small.

In particular, the bottom of the door that slides directly facing the floor does not come into direct contact for smooth rotation of the door while leaving a distance between the floor and the door. However, this separation distance can weaken the sealing function of the door by increasing the gap between the steel door and the door frame and the door and the floor.

In order to solve such a problem, conventionally, an airtight member such as a synthetic resin is applied to the bottom of a door to fill a gap between the door and the floor.

However, the airtight member can not only cause friction due to the actual contact with the floor, noise is generated when the door is operated, and it is difficult for the user to open and close the door.

Accordingly, the present invention has been made to solve the above problems, to minimize the noise and friction force generated when the door is opened and closed by the airtight member installed along the bottom of the door, so that the door can be smoothly closed The technical task is to provide a steel front door of an apartment that is capable of remodeling a flexible gap.

The present invention to achieve the above technical problem,

A door frame, a door that is rotatably connected through the door frame and the hinge, and a door that is opened and closed, a lock barrel having a latch fixed horizontally and rotatably fixed through the lock cylinder and the handle shaft, and the handle shaft is interlocked with the latch. In the front door including a handle,

A first gear fixed to the handle shaft to rotate;

A second gear that is rotatably fixed via the door and the rotating shaft and meshes with the first gear to rotate;

A rotary disk fixed coaxially with the second gear;

A rod-shaped crank arm whose one end is rotatably fixed to the rotary disk; And

A support bar having one end rotatably fixed to the other end of the crank arm, a plurality of connection bars connected downwardly with the other end of the support bar while being disposed along a horizontal length at the bottom of the door, and horizontally at the end of the connection bar A linker comprising a connecting member and a sealing member protruding downward along the lengthwise direction of the connecting member and configured to move up and down together with the support bar, the connecting bar and the connecting member through the bottom of the door;

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view showing a structure for the operation of the airtight member according to the present invention, Figure 2 is a partial cross-sectional view schematically showing the structure shown in Figure 1 installed on the steel front door, with reference to this Explain.

The present invention relates to a front door consisting of a door (400) for allowing a user to enter and exit while indoors and outdoors and a door frame (300) for rotatably fixing the door (400). The front door is a door (400). The airtight member 165 filling the gap between the door frame 300 and the door 400 is inserted into the door 400 during the rotation of the door 400 to minimize friction and interference with the floor.

The door frame 300 for this purpose is installed on the wall surface formed to be cut open for the interior, the door 400 is fixed to the door frame 300 to be rotatable through the hinge 420 disposed on one side. Since the coupling structure and the installation structure of the door frame 300 and the door 400 having a hinged structure are well known technologies, further description of the conventional structure of the door frame 300 and the door 400 will be omitted.

Subsequently, the inside of the door 400 has the following structure.

The airtight member 165 according to the present invention is linked to the operation of a handle (not shown) that the user manipulates when the door 400 is opened and closed. That is, when the user manipulates the handle, the airtight member 165 moves up and down, which will be described in detail below.

As shown in the drawing, a general latch groove 310 is formed in the door frame 300, and a latch 210 installed in the door 400 enters and exits from the latch groove 310. That is, when the user operates by turning the handle, the latch 210 may be fixed to the latch door 310 so as not to open the closed door 400.

The handle for this purpose is a rotary or push type of the operation method, such as automatic or using a manual operation to be operated by the user using the operating equipment, such as a motor, and the like, the above-described rotary, push, automatic and manual are all rotational force Since the operation of the door handle is a way to use the rotational force as the driving force is applicable to the technical idea according to the present invention, and will be carried out within the claims described below.

The lock barrel 200 for manipulating the latch 210 is disposed at one point of the door 400, and the handle is connected to the lock barrel 200. However, the handle is connected to the lock barrel 200 via the handle shaft 110. That is, when the user grabs the handle and rotates it, the handle shaft 110 rotates to transmit the force to the lock barrel 200.

In the embodiment according to the present invention, the handle shaft 110 is connected to the first gear 120, so that when the handle shaft 110 rotates, the first gear 120 also rotates together. At this time, since the handle is generally not rotated 360 degrees structurally, the first gear 120 is limited in the range of the rotation angle. Therefore, rather than forming a complete circle that the first gear 120 can occupy the space unnecessarily, the shape of the bow having it within the required range as shown in order to efficiently utilize the limited space of the door 400 It is desirable to achieve.

On the other hand, the first gear 120 is engaged with the second gear 130 is rotatably fixed to the inside of the door (400). The second gear 130 operates in accordance with the operation of the first gear 120. Since the first and second gears 120 and 130 mesh with each other in parallel, their rotation directions will be opposite to each other.

The first gear 120 rotates in a direction in which the user grasps the handle and rotates it. That is, when the user rotates the handle to the right, the handle shaft 110 also rotates to the right while rotating the first gear 120 downward (see FIG. 4), and when the user turns the handle to the left, the handle shaft 110. ) Rotates the first gear 120 upward while rotating to the left (see FIG. 3).

In the drawing, the contact surfaces of the first gear 120 and the second gear 130 are shown as a simple curved surface without bending, but in reality, they are formed on the contact surfaces of the first and second gears 120 and 130. It would be desirable to engage through. However, the interworking between the first and second gears 120 and 130 is not limited to the above.

On the other hand, according to the present invention, the airtight member 165 should be able to move upward regardless of the direction in which the user grasps the handle and the airtight member 165 is connected to the second gear 130 in a crank manner. .

This will be described in detail below.

The second gear 130 is rotatably fixed to the inside of the door 400 around the rotation shaft 131, it is installed in conjunction with the rotary disk 140 having the rotation shaft 131 coaxial. Therefore, when the second gear 130 rotates in engagement with the first gear 120, the rotating disk 140 also rotates in the same direction.

The rotary disk 140 is connected to the linker 160 via the crank arm 150 having first and second rotary grooves 151 and 152 at both ends thereof.

In more detail, a first rotating groove 151 is formed at one end of the crank arm 150 so as to be rotatably connected to the rotational position of the rotating plate 140 via the first rotating shaft 153. At the other end, a second rotary groove 152 is formed so as to be rotatably connected through the rotation hole 161 and the second rotation shaft 154 of the linker 160.

3 and 4 is a partial cross-sectional view schematically showing the operation of the steel front door according to the present invention, will be described with reference to this.

As described above, when the rotary disk 140 and the linker 160 are connected to each other via the crank arm 150, the crank arm 150 is upward when the rotary disk 140 rotates. The linker 160 is moved up and down while moving. In this case, the crank arm 150 is rotatable with the support bar 162 protruding vertically from the linker 160 so that the crank arm 150 can perform a precise linear motion even in conjunction with the rotary disk 140. Are connected to each other, and the support bar 162 is supported by guides 410 abutting on both sides thereof.

Therefore, as shown in FIGS. 3 and 4, when the user manipulates and rotates the handle, the first gear 120 moves upwards or downwards due to the force, and the second gear 130 moves the first gear. Rotate clockwise or counterclockwise while interlocking with one gear 120. However, since the second gear 130 is coaxially connected with the rotating disk 140, the rotating disk 140 rotates in the same direction as the second gear 130. The rotating disk 140 that rotates in this way is rotatably connected to one end of the crank arm 150, so that the crank arm 150 moves along the rotation of the rotating disk 140, and the crank arm 150 The other end of the linker 160 is rotatably connected to the support bar 162 of the linker 160 moving up and down, so that the linker 160 including the support bar 162 is rotated when the turntable 140 rotates. Go to.

As a result, as shown in FIG. 2, in the state where the latch 210 protrudes, the crank arm 150 is positioned at the lower end of the turntable 140 so that the linker 160 is positioned at the lowest point, and the user's handle manipulation is performed. Since the first gear 120 is rotated when the latch 210 is inserted inwardly, the linker 160 moves upward and moves the airtight member 165 protruding from the bottom surface of the door 400 upward. Will move.

A plurality of connection bars 163 protrude side by side at the end of the support bar 162 of the linker 160, the end of the connection bar 163 is a connecting rod 164 is fixed to the airtight member 165 is disposed. do. In the present invention, the connecting table 164 to which the airtight member 165 is attached is disposed to protrude to the bottom of the door 400. When the support bar 162 is located at the lowest point, the airtight member 165 of the door 400 is disposed. When protruding to the bottom surface and positioned at the highest point, the airtight member 165 moves upward and is inserted into the door 400. As a result, the airtight member 165 does not come into contact with the floor when the door 400 moves, so that the opening and closing of the door 400 is not difficult and the noise due to the friction sound can be eliminated.

According to the present invention as described above, when the door is closed and the latch is inserted into the latch groove of the door frame, the airtight member moves downward to fill the gap between the door and the door frame, and the user turns the handle to open the door. The force of the airtight member moves upwards while the airtight member is not in contact with the floor and does not interfere with the movement of the door, while eliminating friction between the bottom and the airtight member to reduce the noise generated when the door is opened and closed.
