Abstract

The present invention relates to a floor hinge for mounting a hinge that the door is restored to its original position and stopped when the door is opened and released to a desired position among the products applied to the floor door. In particular, the product is designed to be useful in places where people enter and exit frequently, such as tempered glass doors in shops or companies.

Since the hydraulic floor door hinges are operated by hydraulic pressure and strong spring force, it is not only hard to open and close the door, but also when the door is opened rapidly in the direction of closing the door before the door is naturally closed with the initial door open. Due to the strong spring force and the sudden pressure change of the internal hydraulic system, the floor hinge hydraulic system is easily broken. If the hydraulic system fails, the door closes instantly because the door is pulled only by the force of a strong spring. At this time, an object or part of the body is injured between the door frame and the door.

The present invention eliminates the inconvenience of existing when opening and closing doors such as tempered glass doors or front doors, suppresses the deformation of the door frame by powerful spring force, and prevents safety accidents caused by sudden change of position of the door. It is designed to contribute to maximization.

Description

Floor hinge {FLOOR HINGE}

The floor hinge supports a heavy load door made of glass glass or the like and is embedded in the floor to control opening and closing.

A common floor hinge includes a casing that is embedded in the floor and includes a floor hinge assembly, a floor hinge assembly that substantially supports the door and controls rotation opening and closing, and a cover covering and covering the upper portion of the casing.

The structure of the conventional floor hinge will be described in detail.

In general, the floor hinge is provided in the casing, the assembly is made of adjustment screws to support and adjust in the longitudinal and transverse directions, and has a height adjustment screw for adjusting the vertical height, the interview is in close contact with the casing wall by the screw It is made to fix the position.

1 and 2, the body 1 of the floor hinge assembly is formed to be elongated in the longitudinal direction, and a hinge axis for supporting the door and controlling the rotation is provided at one end thereof. In order to fix the body 1 in the casing without flow, adjustment screws are coupled to both sides in the longitudinal direction of the body, and a plurality of adjustment screws are provided on both sides in the transverse direction, and a height adjustment screw penetrating the body from the top to the bottom is moved. After, it is made of both sides.

The longitudinal adjustment screw and the lateral adjustment screw are used to contact the inner wall of the casing so that the body 1 remains in place without flow due to the opening / closing rotational force of the door, and the center of the hinge shaft according to the installation site. In the case of changing, the screw abuts against the inner wall of the four sides of the casing is adjusted.

On the other hand, the vertical adjustment of the floor hinge assembly is to adjust the height of the bottom surface of the hinge shaft by using a height adjustment screw assembled through the body (1) up and down.

Conventional hydraulic floor hinge is configured to close the door by gradually slowing the closing speed as the door closes automatically, so there is no problem when the door is opened and closed slowly. When the door is closed, the door is configured to be operated slowly while the user pushes the door with a strong force to rotate it.

In addition, when the door is closed, some mechanisms have been proposed to prevent the mechanical force applied to the hydraulic floor hinge by opening and closing the valve only when the user has a strong force, but this also prevents the operation of the valve so that the door is closed. Since the speed is not properly controlled, if the door closing speed is too slow, the hydraulic floor hinge will not only give a mechanical strain, but if the door closing speed is too fast, there may be a risk of a safety accident.

The present invention has been devised to solve the above problems, when the door is closed is driven and closed by the mechanical force of the spring's elasticity of the hinge itself, and when the artificial force is applied to the door Is to move freely. In addition, when the artificial force is removed from the door, the door is immediately operated by mechanical force only by the elasticity of the spring, so that the user is not injured by the momentary operation of the door even if the user opens or exits the door. Thus, it is to provide a hinge device that can suppress a sudden position change of the door and maintain a constant tension and a safe closing speed at all times.

In view of the above, the present invention requires frequent entry and exit, and is applied to floor doors using heavy doors such as tempered glass doors or fire doors, so that the door always operates stably, preventing from accidental closing of the door. The purpose is to provide a stable hinge device that can be.

Still another object of the present invention is to provide a hinge device that allows the door to be opened and closed quickly with little force during artificial operation of the door, and the closed state of the door can be maintained at a constant position at all times.

Hereinafter, the operation of the hinge device according to the present invention configured as described above.

First, in the assembled state, although not shown in detail in the drawings, it has a form as shown in Figs.

When the door is opened or closed, the curved surface of the inner surface of the main body 50 has a range of section A, section B, section C and the roller 40 moves within this range.

When the door is opened in the 90 degree position, the position of the roller 40 is located at the vertex 43 closest to the center of the shaft 30 as shown in FIG. 6, and the roller guide 35 is positioned on the shaft ( It is pushed along the penetrated keyway 32 of 30). At this time, the spring 60 is subjected to the maximum compression force and the repulsive force of the spring 60 is the maximum.

When the door is opened more than 90 degrees, the roller 40 moves in the section C, and in the section C in the main body 50 having a smooth surface with respect to the center of the shaft 30, the roller 40 opens in the door. The position is maintained as it is by the balance of the load of the door and the repulsive force of the spring 60 according to the angle. When the door is further opened, the roller 40 is stopped by the stop block 44 and the door is no longer opened.

When the opening angle of the door is 90 degrees or less, when the external force is removed from the door, the roller 40 moves in the section B and the section A along the curved surface inside the main body 50. Section B forms a parabolic curved surface from the closest vertex 43 from the center of the shaft 30 to the vertex 42 that meets the section A, and is provided between the shaft 30 and the roller guide 35. The roller guide 35 is pushed out by the repulsive force of the spring 60, and the roller 40 naturally moves from the vertex 43 to the vertex 42 direction. At this time, the roller 40 moves along the curved surface of the section B by the force of the spring 60 and has a slight speed while the door is closed. When the roller 40 moves from the section B to the section A, the roller 40 decelerates while passing through a gentle straight section, which is a characteristic of the section A, and the door 40 is slowly closed, so that the roller 40 has the shaft 30. The vertex 41 farthest from the center of the center is reached and is positioned in place by the repulsive elastic force of the spring 60.

When the door is in the closed state, the elastic repulsive force of the spring 60 is minimized, and the roller 40 is stopped at the vertex 41 farthest from the center of the shaft 30 and stops. The position is always positioned at the vertex 41 due to the nature of the spring 60 to minimize the repulsive force of the spring 60.

Based on the above description, depending on the design of the curved surface of the inner surface of the main body 50, it will be appreciated that the opening and closing range of the door can be up to 360 degrees.

As described above, the hinge device according to the present invention has a form in which the roller is in contact with the inner surface of the body when the door is opened and closed, so that the roller rolls the inner surface. There is no need to adjust the speed, so there is no sudden change of position of the door due to the failure of the hydraulic system, so it can be permanently escaped from the safety accident. In particular, it is very easy to enter and exit frequently, such as doors equipped with tempered glass or doors of general fire doors, and minimizes damage to the floor surface due to less space required for installation. In addition, when oil is filled in the hinge body, smoothness and semi-permanent service life can be achieved when the door is opened and closed, and a sudden change in the door can be prevented from safety accidents.

The present invention is not limited to the construction and operation as shown and described as such. Therefore, all appropriate changes, modifications, and equivalents should be considered to be within the scope of the present invention.
