Utility Model Registration No. 20-0156792 'Hydraulic Floor Hinge',

Utility model registration No. 20-0151773, "reciprocating body of the floor hinge," and the like.

Conventional floor hinges as described above have a vertically installed hinge shaft inside the casing, the piston is advanced and retracted according to the rotation of the hinge shaft is connected to the piston rod is disposed long in one direction, the spring in the piston rod This structure adopts a structure that allows the door to close itself by obtaining an elastic restoring force from the spring as the piston moves forward and backward.

However, the structure that generates hydraulic pressure by moving the piston by using a separate rod as described above, there is a disadvantage in that the structure is complicated by the increase in the number of parts is not only difficult to manufacture, but also the process of assembling the product is not easy and the problem frequently occurs There is this.

In order to solve such a problem, the applicant has filed a patent application No. 10-2008-0084471 "floor hinge".

The floor hinge as described above has a casing in which a working space is formed, the inside of which is closed by a stopper, and a hinge hole is formed at one upper portion thereof, and a hinge is installed vertically through the hinge hole, and a cam is formed at the bottom thereof. A piston installed in the operating space and reciprocating by the rotation of the cam and having a roller supporting the cam at the center of the body and a force disposed at the rear of the piston to return the piston to its original position. It consists of a spring to give.

The floor hinge, which has been filed by the present applicant as described above, can minimize the number of required parts, increase the convenience of manufacturing and simplify the assembly of the finished product, and also have a spring that provides the cam with direct drive and restoring force. The direct support of the piston simplifies the construction of the floor hinge, improving the reliability of the product to avoid frequent failures.

The floor hinge of the prior application having such a structure causes the piston to move forward and backward while the cam integrally formed with the hinge shaft rotates in the same direction as the rotational direction of the hinge shaft, and thus the spring repeats compression and restoration.

However, as the spring is repeatedly compressed and restored as the piston retreats, the elastic restoring force is attenuated as the spring ages with the use of a long time, thereby weakening the force for pushing the piston.

In particular, in the case of a spring wound in the form of a coil made of metal, as the length increases, the elastic restoring force for restoring the spring to its original state after the compression is attenuated by repeated compression and restoration after a long time of use. You can't. Therefore, there is an inconvenience of replacing the old spring with a new spring.

In some cases, when the elastic restoring force of the spring pushing the piston acts on the piston forcibly, the door is closed at an excessive speed when the door is closed by an external force, leading to an accident in which the door and the door collide.

Therefore, in order to control the speed of the door to be closed, the elastic restoring force of the spring that gives the force to return the piston to its original position must be controlled. Control of the components reduces the compatibility of parts, which reduces the productivity and maintenance of the product.

The present invention is to solve the above problems, to simplify the structure of the floor hinge assembly to minimize the number of parts required to improve the convenience of manufacturing and to simplify the assembly of the product, to prevent frequent failures The purpose is to provide a floor hinge assembly.

An operating state of the floor hinge assembly according to the present invention having the above configuration will be described based on FIGS. 4 and 5.

4 and 5 are a plan sectional view showing an operating state of the floor hinge assembly according to the present invention, FIG. 4 is a plan sectional view with the door closed, and FIG. 5 is a plan sectional view with the door open.

Referring to the drawings, the casing 100 is embedded in the door installed in the doorway of the building, the hinge shaft 200 protruding on one side of the upper end of the casing 100 is axially coupled to the lower side of the door to the door The hinge shaft 200 rotates as it opens and closes.

In the closed state of the door, the piston 300 is positioned in a state where the piston 300 is advanced (in the left direction on the drawing) by the first spring 410 and the second spring 420, and thus the cam 210 is closed. The roller 320b formed in the cam receiving space 310 is held in the locking groove 212a formed at the rear.

When the door is opened, the roller 320b is separated from the locking groove 212a so that the cam 210 rotates clockwise (counterclockwise when the door is opened in the opposite direction). At the same time, the cam 210 pushes the roller 320b to retract the piston 300 in the working space 110 of the casing 100 (to the right in the drawing), and to retract the piston 300. Accordingly, the first spring 410 and the second spring 420 are respectively compressed.

That is, when the piston 300 retreats in the working space 110 formed in the casing 100, the partition wall 112 formed in the working space 110 through which the rod 340 extending from the piston 300 penetrates; The first spring 410 provided between the piston 300 is compressed, and the second spring 420 provided between the flange 350 and the other end 130b is compressed.

As such, when the door is rotated by 90 degrees, the roller 320b is caught by the locking groove 212b formed at the side of the cam 210, thereby maintaining the open state without closing the door.

On the other hand, when closing the door to maintain the open state, the roller 320b is released from the locking groove 212b by slightly pushing in the direction opposite to the rotation direction when the door is opened.

As such, when the roller 320b is separated from the locking groove 212b, the elastic restoring force is exerted in the first spring 410 and the second spring 420 in a compressed state at the rear of the piston, thereby advancing the piston 300. Leftward in the drawing).

As described above, by the elastic restoring force exerted by the first spring 410 and the second spring 420, the engine 300 moves forward in the working space 110 and returns to its original position before the piston 300 retreats. At the same time, in the process of returning the piston 300 to the original position, the roller 320b is rotated in the opposite direction when the cam 210 is opened to rotate the hinge shaft 200 and the door according to the rotation of the hinge shaft 200.

By adjusting the distance between the other end cap 130b for sealing the other side of the first spring 410 and the second spring 420 can control the distance from the compression to the restored distance, accordingly the first The elastic restoring force of the spring 410 and the second spring 420 may be controlled.

To this end, a fastening hole 302 having a thread is formed on the rear surface of the piston 300 facing the first spring 410, and a thread is formed at one end 340a of the rod so that the fastening hole 302 is formed. One end 340a of the rod is screwed together.

In addition, a threaded through hole 352 is formed in the flange 350, and a thread is formed in the other end 340b of the rod to thread the other end 340b of the rod to the through hole 352. .
