Description

Hinges for swing doors{HINGE FOR HINGED DOOR}

The disclosed content relates to a hinge for a swing door that has a simple hinge structure and can be easily fastened to the door frame.

Unless otherwise indicated herein, the matters described in this identification are not prior art to the claims of this application, and are not admitted to be prior art by being described in this identification.

In general, the entrance door used in a greenhouse is made by cutting square steel pipes to specifications and fusing them together to form the entrance door. A vinyl fixing groove pad is fixed to the door frame with a piece, and a vinyl fixing wire is installed in the vinyl fixing groove to secure the vinyl. It is manufactured by fixing it.

At this time, the installation time and cost of the door are excessive, there are cases where the welded part is damaged due to corrosion during use, and there are many difficulties in dismantling the door.

Accordingly, hinges used in entrance doors are being developed to ease installation time and cost.

Meanwhile, a swing door generally refers to a door that is opened by pushing or pulling in or out by installing one or more hinges on the door frame and edge of the door, and is distinguished from a sliding door that opens and closes by pushing left and right.

Here, swing doors are used not only as entrance doors to various buildings or offices, but also as greenhouse doors, and hinges used in swing doors are developed in various forms depending on the purpose of use.

As an example of such a door hinge, Korea Registered Utility Model No. 20-0186543 (announced on June 15, 2000) states that a frame used for the entrance door of a greenhouse is easily constructed by bending a steel plate material, and then cutting it and attaching it with fastening bolts. The purpose is to manufacture entrance doors and provide an entrance door frame for greenhouses that can easily and quickly attach vinyl. The frame is constructed by bending steel plates, with an inner groove in the center of the bottom of the frame and an outer groove in the upper part. While forming the upper part, the outer plate is inclined inward to have a support surface and support force, so that it is configured to form a lower beam. This design is easy to manufacture the frame, so it can be mass-produced, and the frame is cut into squares. A greenhouse door frame is being disclosed that can easily manufacture doors and door frames using connecting plates and fastening bolts, and can easily fix vinyl to the doors and door frames.

In addition, Republic of Korea Patent No. 10-1213127 (announced on December 18, 2012) includes a hinge unit that rotatably connects a door to a door frame; and a door return unit provided on the hinge unit to provide a rotational force due to torsional elasticity to the door so that the door automatically closes, and the door return unit is mounted on the hinge unit to close the door. It is composed of a torsion member that is provided with a torsion for automatic closing, and a torsion supporter provided in the hinge unit to provide a torsion to the torsion member, so that the automatic closing function of the rotating body, that is, the swing door, can be secured. Since the hinge device performs the function of a rotating shaft and a door closer at the same time, a hinge device that greatly improves convenience in installation and use and a hinged door having the same have been disclosed.

In addition, Korea Registered Utility Model No. 20-0194674 (announced on September 1, 2000) has a pipe-shaped hinge body with hinge wings attached to the top and bottom with a thrust bearing inserted in the middle, and the upper and lower parts on the outside. Insert a rod-shaped operating rod on which an operating spring is inserted, the upper end of the operating spring is fixed to the operating rod, the lower end is fixed to the operating stopper screwed to the hinge body, and the upper and lower ends of the operating rod are fixed. Grooves are formed at regular intervals around the outer circumferential surface, and holes corresponding to the grooves are drilled on the outer circumferential surfaces of the upper and lower parts of the hinge body, and the movable ball and spring are sequentially inserted from the inside to the outside within these holes and are tightened with a wrench bolt from the back. As it is fixed, the door opens with an appropriate pressure adjusted by the operating spring and other devices, stops on its own even when released at a certain angle, and closes automatically without installing a separate device, allowing the door to open and close. Hinges for swing doors that allow for the most convenient operation are being disclosed.

However, the door frame of the greenhouse as described above is not easy to fold the steel plate to form a door frame, and the sharp threads of the assembly bolts may protrude outside the nut, so separate grinding work is required for user safety. There is a necessary problem.

In addition, the hinge device and the hinged door having the same are disclosed in a structure equipped with a torsion member or spring built into the pivot axis, but too many parts are required and the manufacturing cost is high, making it difficult to apply to simple hinged doors such as greenhouse doors. There is a problem.

In particular, the greenhouse entrance door is equipped with a door frame with pipes as the main frame, and if necessary, a swinging door without a threshold with a large door frame is required to allow smooth passage of handcarts or agricultural machinery. The conventional swing door used for this is As hinges are used by modifying those used for general building entrance doors, they have short service life and cannot be firmly fixed.
