Description

Hinge structure for door reorganization

The present invention relates to a hinge structure for opening and closing the door, and more particularly, the structure of the hinge that is installed to enable the opening and closing of the door in front of various storage bodies such as a wardrobe or a student locker has a special appearance after installation. In addition, the installation state is also very strong and strong, and there is no gap in the hinge part, so there is no fear of injury due to fingers being caught during opening and closing of the door. It is a hinged structure for door opening and closing, which has a long life span so that there is no deformation or breakdown of form due to its excellent resilience to the original state after impact.

In general, closets, lockers, storage boxes, etc. are installed in homes, offices, schools, public baths, etc., and are called in various forms and names depending on their purpose.

Such closets, lockers, storage boxes, etc., and a storage body for storing the contents,

It consists of a door that opens and closes the front of the tooth,

Here, the door is configured by hinge-locking the rotating piece which is fixed to the door to the fixed piece that is fixed to the upper and lower sides of the receiving body to be rotated in various ways,

Conventional hinges are made of a metal material to simply lower the manufacturing cost as shown in the accompanying drawings, Figure 1, while the overall configuration is too simple to configure the overall configuration, but the installation state is not robust as a whole, In terms of characteristics, the hard feeling was not only beautiful in appearance but also rusted or peeled off the coating layer.

And, since the hinge coupling part is mostly exposed to the outside, when the door 220 is opened and closed, the hinge 1 is connected, that is, the gap 2 is opened between the receiving body 210 and the door 220 and the door During the opening and closing of the 220, injuries caused by the fingers of the distracted children, etc. were often caused.

In addition, when the hinges 1 of the conventional metal material are subjected to an external impact such as pulling or hanging the door 220 from the outside or kicking with a fist or a foot, deformation such as bending or bending occurs once due to the characteristics of the metal material. After being deformed, it does not naturally return to its original state, so when it is not used for a while, it does not work smoothly when it is opened and closed, and the breakdown frequently occurs, which shortens the overall service life, and requires high costs for maintenance or replacement. There were various issues of.

The present invention has been devised in view of the above-mentioned conventional problems,

After the hinge itself is manufactured from high strength and high elasticity synthetic resin and installed at the same time, by providing a high quality and high quality hinge door structure, the front of the fixing piece is installed to cover the entire side of the door.

The appearance is very beautiful and the installation is also very solid and durable,

Make sure there are no gaps at the hinges so that your fingers are caught during the opening and closing of the door, so that there is no fear of injury.

The purpose of the door is to make the opening and closing of the door soft and responsive to external shocks so that the restoring force to the original state after the impact is excellent so that there is no deformation of the form at all, making it convenient to use.

The present invention for achieving the above object is a fixing piece 110 is fastened by fastening the screw 151 to the inner surface of the various receiving body 210, such as a wardrobe or student locker as shown in the accompanying drawings, Figures 2a to 3c and,

It is used to open and close the door 220 consists of a rotating piece 120 which is fastened to the door 220 by a hinge shaft pin 130 so as to be rotatable to the fixing piece 110.

Here, the fixing piece 110 of the present invention,

It is formed from a synthetic resin material having a plurality of high strength and high elasticity.

In addition, the rotating piece engaging portion (110a) is formed integrally in the middle portion of the fixing piece 110, the rotating piece coupling portion (110a) is one side open from the front to the predetermined length from the front and the other side is blocked. It is formed to be.

And, the rotating piece 120 of the present invention,

It is hinged to the rotating piece coupling portion 110a formed on the fixing piece 110 by using a hinge shaft pin 130, which is also formed of a synthetic resin material having high strength and high elasticity as in the fixing piece 110.

Such rotation piece 120 is predetermined to be inserted into the rotation piece coupling portion (110a) by a predetermined length rearward from the hinge coupling portion when coupled to the rotation piece coupling portion (110a) of the fixing piece (110). The bent portion bent at an angle of 90 ° outward from the length portion is formed integrally.

Therefore, when one side end inner surface of the door 220 is fastened to the front surface of the bent portion of the rotating piece 120 by screw 152, the front of the fixing piece 110 to which the rotating piece 120 is coupled is the entire side of the door 220. It is installed to cover.

On the other hand, the present invention may be used by connecting the auxiliary fixing piece (not shown) in the middle of the fixing piece 110 when the installation length of the hinge 100 is long.

Here, the rotating piece coupling portion 110a is not formed in the auxiliary fixing piece, but may be used to selectively form the rotating piece coupling portion (110a).

Reference numerals 111 and 121 are threaded holes, and another reference numeral 140 is a cap coupled to a hole formed at an upper side and a lower side.

It describes the state of use of the present invention door opening and closing hinge 100 configured as described above.

First, the hinge engaging portion of the rotating piece 120 is positioned on each of the rotating piece coupling parts 110a formed at the middle of the upper fixing piece 110 and the lower fixing piece 110, and then rotates using the hinge shaft pin 130. Coupling piece 120 is rotatable.

In this state, the fixing pieces 110 are fastened to each other by fastening screws 151 on the inner surfaces of the various receiving bodies 210 such as a wardrobe or a student locker.

Then screw 152 the inner surface of one end of the door 220 on the front surface of the bent portion of the rotating piece 120 hinged by the hinge shaft pin 130 to the rotating piece coupling portion (110a) of the fixing piece (110) Tighten.

If you do the above can be completed installation of the hinge 100 of the present invention very simply, of course,

After installing the hinge 100 of the present invention, the front of the fixing piece 110, that is, the front projecting part of the hinge 100 of the present invention is installed to cover the entire side of the door 220, the appearance is very beautiful, The installation state of the hinge 100 is very solid and strong.

In addition, even when the door 220 is smoothly opened and closed, even when an external shock such as pulling or hanging the door 220 or kicking with a fist or foot is applied, the shock absorbing ability is excellent and the restoring force to the original state after the impact is excellent. There is no deformation, so there is no breakdown even after long-term use.

The hinge of the present invention as described above is easy to assemble and install,

The hinge itself is made of high strength and high elasticity synthetic resin and at the same time, after installation, the front of the fixing piece is combined to cover the entire side of the door, so the appearance is very beautiful.

Of course, the hinge is very solid and sturdy,

There is no gap at the hinge part, so there is no risk of injury due to your fingers getting caught during the opening and closing of the door.

In addition, the opening and closing of the door is smooth,

It responds elastically to external shocks, so it has excellent shock absorbing power and excellent restoring force to its original state after impact.

Therefore, the hinge of the present invention is a very innovative design that can be satisfied simultaneously with the supplier and the user, such as smooth opening and closing operation even after long use, there is no breakdown, the overall service life is long, and the cost of maintenance or replacement is saved. It is
