KR200348750Y1 - Clearance opening at the bottom of the door - Google Patents

Abstract

The architecture that removes the threshold of the visit is novel, but there is a gap under the door and there is no preventive measure.

The design of the present invention is to lift and lower the seat and pull down between L and pull the L and pull the corner between L and the permanent magnet embedded in the edge of the door. On the contrary, the permanent magnets move away from each other when the door is closed and the door is raised to open and close the gap.

Description

Clearance opening at the bottom of the door {omitted}

It is to provide an automatic opening and closing device that prevents the door of the door and the bottom of the door is left open due to the architectural wind that prevents the door from closing on the floor.

If you remove the door at the door, you will not be caught by the foot, but the bottom of the door is slightly lifted, so it is unprotected against the invasion of cold wind, dust, and insects, and the technology to prevent the closure has not been developed.

When the door is closed at the bottom of the door, it descends and closes the gap at the bottom of the door, and when the door is opened, it rises first to configure the device that automatically opens and closes the gap when opening and closing the door.

A. Configuration

In the present invention, when the door is closed, the door is lowered to close the open gap under the door, and when the door is opened, the door is raised first to open and close the door without scratching the floor. Let's configure.

In other words, the space 2 is formed at the lower side of the door 1 with the lower end open, and the left and right L spaces 3 and 4 are laid on the front wall so as to be able to rotate about an axis. (3 ') and (4'), each of which has a loop at both ends and connects the upper end of the annual (5) (6) which can be connected between the two actuators, and the lower end is long, ragged and rubber-coated. And suspended the hooks (8) and (9) at the upper left and right sides of one of the subplates (7), respectively. Each end of the), taste the holes of the object and insert the short axis to observe the joints to form a four-sided joint, insert the spring (12) on the left side of the left medal (11) The left end of the rod 12 was attached to the rod 12, and the spring 14 was fitted to the right end of the rod 12, and the right end 15 was pivoted in a hole having a shaft, and the right end of the rod 12 was rubbed. 19) Rain with side fixed It is connected to the inner end (N pole) of the movable permanent magnet 17 inserted into the metal barrel 16, and the outer S pole extends only to the right end of the door 1, and stops. When the door 1 is almost closed, the movable permanent magnet is closed. The permanent magnet 18 was buried in the rubbing 19 as shown in FIG. 1 so that the S pole of (17) and the N pole of the fixed permanent magnet 18 approached most.

B. Action

When the door having the device of the present invention is opened as described above, in Fig. 1, the springs 12 and 14 push the upper L (3 "and 4") between L to the left, and the lower angle between L (3 ') and 4'. ) Maintains the horizontal posture, so that the state of the vehicle plate 7 is pulled up to the maximum.

When the door 1 is rotated by 90 degrees to close it, the door 1 is caught by the jaws of the door 19, and the catch of the handle is locked.

The device of the present invention embeds a permanent magnet (18) in front of the locking jaw of the door (19) as shown in Figure 1 and closes the door (1), the movable permanent magnet (17) is fixed permanent magnet (18) and Come to the opposite position. At this time, the N pole and the S pole of both magnets are attracted to each other, but the permanent permanent magnet 18 is buried at the edge of the door and is fixed, so the movable permanent magnet 17 is pulled out and comes to the edge of the door to stop. (10) pulls the upper angle (3 ", 4") between L to the right, so the ends of the lower angles (3 ') and (4') are lowered, and the lower plate (7) is lowered as shown by the imaginary line. It acts to close the gap.

When the door is opened, the movable permanent magnet (17) of the door moves away from the magnetic field of the fixed permanent magnet (18) of the door, so that it is pulled by the force of the spring (12) (14) to the movable permanent magnet (17). In the process of returning to the original height and opening and closing the door, the bottom is not scratched and only when the door is completely closed, the bottom opening and closing action is performed to close the open state under the door.

The device devised by opening and closing the gaps under the door as needed as described above, the construction to eliminate the door to the door has eliminated the bleeding foot, but it does not prevent the side effects of the gap under the door to completely solve the trouble It is a new and beneficial device with the effect of further developing such architecture.

Claims (1)

Create a space open downward to the lower side of the door, and lay the intermediate point between L (3) (4) on the front wall of the door and annually (5) () at the lower angle (3 ') (4'). 6) Suspend the vehicle plate 7 with the upper edge 4 " attached to the left end of the rod 10, insert the spring 12, and again pass the left end 11 through the left medal 11 to L ( The spring 14 is inserted into the rod 13 which is attached to the upper angle 3 "of the upper part 3) and the left end is attached to the upper angle 3", and the right end penetrates through the right medal 15, and is inserted into the nonferrous metal barrel 16. It is connected to the left end of the movable permanent magnet (17) and the gap opening and closing device at the bottom of the door formed by embedding the fixed permanent magnet (18) on the edge of the door (19).
