Abstract

The present invention relates to a door structure combined with a hydraulic hinge and a spring hinge.

It is constructed by attaching a hydraulic hinge to the upper part of the door, similar to the existing hinge, and attaching a spring hinge to the lower part. In particular, it is configured to smoothly open and close by providing elasticity by the spring hinge when the door is opened and closed, and providing a shock action by the piston reciprocating in the hydraulic fluid inside the hydraulic hinge.

Description

Door structure with fluid hinge and spring hinge

The present invention relates to a door structure coupled to the fluid hinge and the spring hinge.

In case of swing doors, many types of door hinges are used to keep the closed doors intact and to mitigate the impact of sudden closing.

As an example, the door closer in the form of a link is installed at the upper part of the entrance of the building, and the structure configured to open and close the door smoothly by the elasticity of the spring and the buffering action of the fluid is mainly used. There was a problem with the appearance or poor appearance of the door.

Moreover, the door hinge comprised by the vertical type used for the entrance door of a building etc. is generally used in the form in which part is buried inside the building. In such a buried type, it is configured to use by combining one side of the door upwards on the hinge. However, since various contaminants and impurities may be introduced during cleaning to the part which is buried in use, there is a problem that it is difficult to disassemble during maintenance.

In the present invention, it is designed to be attached to the door and the like with the same shape and size as the existing hinge, it is designed to provide a flexible shock-absorbing function using the elastic opening and closing by the spring hinge.

The hydraulic hinge is configured such that when the upper plate attached to the door rotates and returns about the door frame, the piston coupled inside the housing moves up and down the inside of the hydraulic fluid having a constant viscosity, so that the upper plate is affected by the viscosity of the fluid and the resistance of the piston. Is configured to operate at a constant speed,

In the case of the spring hinge, when the upper plate rotates and returns, the coil spring wound inside the housing is wound or imparts elasticity to remain intact, thereby always giving a constant elasticity to the door.

Therefore, in this paper, not only the door is kept elastic at all times, but also the elasticity is prevented, and the door is prevented from being opened by a sudden force, and the cushion is provided so as not to be suddenly closed.

The door that is configured in the form of a hinge is fixed in one corner and rotated by a predetermined section about the fixed portion. Hinges are essential for this fixing.

In this paper, it is comprised by combining the hydraulic hinge 1 and the spring hinge 12 with the hinge part which comprises an entrance door.

The hydraulic hinge 1 is coupled to the upper end of the door 22. The change of the inside of the hinge according to the opening and closing of the door is shown in FIGS. 1 and 2.

1 shows the hydraulic hinge 1 inside the door is closed. The hydraulic hinge (1) consists of a lower plate (4) attached to the door frame and an upper (2) plate attached to the door, and inside the hydraulic hinge (1) by reciprocating movement of the upper plate (2) attached to the door. The piston 6 is configured to reciprocate inside the fluid so that a buffer action is effected by the resistance between the fluid and the piston.

The upper plate 2 and the lower plate 4 constituting the hydraulic hinge 1 are each composed of housings 3 and 5, and each lower plate (inside the housings 3 and 5) is formed. 4) and the fixed helical rod 9 and the upper plate 2 and the fixed piston 6 are combined.

A spiral rod 9 is vertically fixed inside the housing 5 which is integrally coupled with the lower plate 4, and a piston 6 is engaged inside the housing 3 of the upper plate 2. It is.

In the state in which the door is closed as shown in FIG. 1, the open part of the lower end of the piston 6 is kept slightly over the end of the spiral rod 9, and when the door is opened as shown in FIG. 2, the upper plate 2 rotates. The piston 6 is then lowered down while rotating downward along the helical rod. Each housing (3) (5) into which the helical rod (9) and the piston (6) is inserted is filled with hydraulic fluid (10) and these components are always operated in a submerged form.

The upper end of the piston is equipped with a check valve (8) is made when the piston is lowered when the door is opened, at this time the hydraulic oil (10) is drawn out to the check valve (8).

On the other hand, the door 22 in the open state is always received by the spring hinge 12, when the door is released, the door is moved to the closed state by the elasticity of the spring. At this time, the piston (6) inside the hydraulic hinge (1) is made to move in the opposite direction of the spiral rod (9) is made to move to the upper portion of the spiral rod (9).

In this case, the hydraulic fluid 10 does not move through the check valve 8 in the center of the piston, but the fluid moves through the narrow orifice 7 formed by the side of the piston 6 and the respective housings 3, 5. This provides resistance to fluid movement, so the door closes slowly. The upper end of the housing (3) formed on the upper plate (2) is equipped with a control valve (11), it is configured to adjust the speed of fluid movement inside the housing (3) (5) when the door is opened and closed According to the weight of the door, it was configured to provide an appropriate cushioning force.

The spring hinge 12 mounted on the door structure has a coil spring 18 mounted inside the housings 14 and 16 of the upper plate 13 and the lower plate 15 to the door 22 during opening and closing. It was configured to provide elasticity by torsion of the coil spring 18.

The spring hinge 12 also has a hinge shape in which the upper plate 13 and the lower plate 15 are coupled to each other, and is coupled to the housings 14 and 16 formed on the respective plates 13 and 15. To form the interior of the cylinder. A fixed rod 17 is mounted inside each of the cylindrically coupled housings 14 and 16, and a coil spring 18 is coupled to the outside of the fixed rod 17.

The spring end of the coil spring 18 is fixed to the housing 14 constituting the upper plate 13, and the other spring end 19 is fixed to one side of the housing 16 constituting the lower plate 15. It is. In the state in which the door 22 is closed, the coil spring 18 is fixed in a non-elastic state, and when the door 22 is opened, the coil spring 18 has a wound shape to provide elasticity. In addition, the adjustment plate 21 is attached to the housing of the lower plate is configured to adjust the elasticity of the coil spring 18 according to the weight and opening and closing strength of the door.

By making and combining similar size with the existing hinge, it has a beautiful effect in the simple appearance in the door structure, and the effect of providing a smooth opening and closing due to the buffering action of the hydraulic hinge with the elastic original return function of the spring hinge. have.
