Description

HINGE FOR HINGED DOOR WITH PLATFORM

The disclosed subject matter relates to a hinge for a swing door having a simple hinge joint structure, which can be easily attached to a door frame and a door, and a step formed so that the door can be fixed in a closed state.

Unless otherwise indicated herein, the matters described in this identifier are not prior art to the claims of this application, and their description in this identifier is not intended to be an admission that they are prior art.

Typically, doors used in vinyl greenhouses are manufactured by cutting square steel pipes to specifications and fusing them to form a door, fixing a vinyl fixing groove pad to the door frame with a piece, installing a vinyl fixing wire into the vinyl fixing groove to fix the vinyl.

At this time, the installation time and cost of the door were excessive, there were cases where the door was damaged due to corrosion of the welded part during use, and it was also difficult to keep the door closed without a fixing device.

Accordingly, hinges for doors are being developed to facilitate the installation time and cost of doors.

Meanwhile, a swing door is generally a door that is opened by pushing or pulling in or out, with one or more hinges installed on the door frame and the edge of the door leaf, and is distinguished from a sliding door that is opened by pushing left or right.

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

As an example of such a door hinge, Republic of Korea Utility Model Registration No. 20-0186543 (announced on June 15, 2000) discloses a door frame for a vinyl house that is easily constructed by bending sheet metal to form a frame used for the door of a vinyl house, and that is manufactured by cutting and joining the frame with fastening bolts, and that vinyl can be easily and quickly attached. The frame is constructed by bending sheet metal, and an inner groove is formed in the center of the bottom of the frame and an outer groove is formed in the upper part thereof, and the outer plate is inclined inwardly so as to have a support surface and support force in the upper part so that the lower plate can be supported, and the lower plate can be easily manufactured and mass-produced. In addition, the present invention discloses a door frame for a vinyl house that is easy to manufacture because the frame is easy to manufacture and can be mass-produced by cutting the frame to a certain size and using a frame connecting plate and fastening bolts to easily manufacture the door and door frame, and that vinyl can be easily fixed to the door and door frame.

In addition, Republic of Korea Patent Registration No. 10-1213127 (announced on December 18, 2012) discloses a hinge device and a swing door having the same, which comprises a hinge unit that rotatably connects a door to a door frame, and a door return unit that is provided on the hinge unit to provide a rotational force by torsional elasticity to the door so that the door automatically closes, wherein the door return unit comprises a torsion member that is mounted on the hinge unit and is provided with a torsion for automatic closing of the door, and a torsion supporter that is provided on the hinge unit to provide a torsion to the torsion member, thereby ensuring an automatic closing function of the rotating body, i.e., the swing door, and since the hinge device performs the function of a door closer as well as the function of a rotational shaft, the convenience in installation and convenience in use are greatly improved.

In addition, Republic of Korea Utility Model Registration No. 20-0194674 (announced on September 1, 2000) is a hinge body in the shape of a pipe with hinge wings attached to the upper and lower parts while a thrust bearing is inserted in the middle, and a rod-shaped operating rod with an operating spring inserted at the upper and lower parts on the outside is inserted, and the upper end of the operating spring is fixed to the operating rod, and the lower end is fixed to an operating plug screwed to the hinge body, and grooves are formed at regular intervals on the outer surface of the upper and lower parts of the operating rod, and holes corresponding to the grooves are bored on the outer surface of the upper and lower parts of the hinge body, and a moving ball and a spring are sequentially inserted from the inside to the outside in the holes and fixed from the rear with a wrench bolt, so that the door opens while being controlled by an appropriate pressure by the operating spring and other devices, and the door stops by itself when released at a certain angle, and the door closes automatically without installing a separate device, so that opening and closing the door is easy. A hinge for a swing door that allows maximum convenience of operation is disclosed.

However, as mentioned above, the door frame of the vinyl house is not only difficult to form by folding sheet metal into a door frame, but also has the problem that the sharp screw threads of the assembly bolts can protrude outside the nut, requiring additional grinding work for the safety of the user.

In addition, although a hinge device and a swing door having the same are disclosed with a structure equipped with a twisting torsion member or spring built into a pivot axis, there is a problem that it is difficult to apply to simple swing doors such as greenhouse entrance doors because too many parts are required and the manufacturing cost is high.

In particular, the greenhouse entrance door is equipped with a door frame with a pipe as the main structure, and if necessary, a large door frame and a swing door without a threshold are required so that a cart or farm machinery can pass through smoothly. However, the conventional swing door hinges used for this purpose have been modified from those used for general building entrance doors, and therefore have the problem of a short service life and inability to be firmly fixed.

In addition, there is a problem in that it is cumbersome to fix the heavy door in a closed state because a separate fixing member must be provided to fix the door in a closed state because it is formed of a pipe.

1. Republic of Korea Registered Utility Model No. 20-0186543 (Publicly Announced on June 15, 2000) 2. Republic of Korea Patent No. 10-1213127 (announced on December 18, 2012) 3. Republic of Korea Registered Utility Model No. 20-0194674 (Publicly Announced on September 1, 2000)
