Description

PVC turning door with built-in type door closer}

The present invention relates to a PVC turning door with an embedded door closer. More specifically, the door closer that controls the opening and closing of the turning door is embedded and fixed on the upper surface of the turning door, thereby preventing damage to the product due to exposure of the structure. It improves marketability by increasing the aesthetics of the product, and the link member connected to the door closer and guide rail is easily fixed through the fixing part, shortening assembly time, and forming a seal between the turning door and the door frame provides sound insulation and wind protection. This is about a PVC turning door with a built-in door closer that maximizes effectiveness.

Generally, door closers are installed on entrances, evacuation stairs, and study area fire doors installed in homes or commercial buildings to keep the door completely closed even in the event of a fire or without direct force from the user. .

The door closer as described above is configured so that when a person opens the door, enters or leaves the door, and then lets go of the door, the door slowly closes with hydraulic force through a hydraulic system installed in the door closer, and then closes quickly at the end.

However, since the above-mentioned door closer is exposed to the outside of the door, it not only interferes with external structures, but also causes damage to the product due to exposure. Above all, the aesthetics of the product are reduced and its marketability is significantly reduced. There was a problem.

As shown in FIG. 4, the link member 151 is formed to have a certain length, one end is coupled to the shaft 121 formed at the top of the door closer 120, and the other end is coupled to the guide 152. It is coupled to the axis 152a.

Coupling spaces 151b that are open outward are formed at both ends of the link member 151.

The guide 152 is slidably coupled to the lower part of the guide rail 130, and the other end of the link member 151 is coupled to the lower part of the guide 152.

As shown in Figures 5 and 6, the fixing part 153 fixes the link member 151 to the axis 121 of the door closer 120 and the coupling axis 152a of the guide 152.

The fixing part 153 is formed as a circular plate body and is provided with fixing members 153a located at both ends of the link member 151, and the fixing member 153a has a fixing space 153b open in one direction. It is provided and coupled to the shaft 121 of the door closer 120.

A guide hole (153c) is formed penetrating in a semicircular shape based on the center of the fixing member (153a), and the guide hole (153c) is opened while the fixing member (153a) is located on the link member (151). A control member 153d is provided that is coupled to the link member 151 and controls the fixing member 153a to rotate only at a certain angle while allowing the fixing member 153a to rotate.

A fixing member 153a is protruded from one end of the fixing member 153a to rotate the fixing member 153a.

That is, the fixing part 153 configured as described above is configured to operate the door closer 120 with the coupling space 151b of the link member 151 and the fixing space 153b of the fixing member 153a positioned on the same line. After coupling to the axis 121, when the fixing member 153a is rotated 90°, the fixing space 153b is shifted from the coupling space 151b and the axis 121 of the door closer 120 is fixed. do.

The coupling shaft 152a of the guide 152 is also fixed in the same manner as the shaft 121 of the door closer 120.

A stepped portion 160 is formed on the edge of the turning door 10 and is in close contact with the outer surface of the door frame 11.

In addition, as shown in FIGS. 7 to 9, a sealing portion 170 is provided on one side of the door frame 11 and the turning door 10 to seal between the door frame 11 and the turning door 10. More may be provided.

The sealing part 170 is composed of a first sealing member 171, a second sealing member 172, and a third sealing member 173, and is fixed with a fixing screw or an adhesive.

The first sealing member 171 is fixed to the inner edge of the turning door 10, has at least one outer sealing protrusion 171a protruding in the outer direction of the turning door 10, and the second sealing member 171 is A receiving groove (171b) is recessed inward in the direction of the sealing member (172).

On the other side of the outer sealing protrusion 171a, an inclined surface 171c is formed that is inclined at a certain angle and comes into close contact with the second sealing member 172 when the turning door 10 is closed.

The second sealing member 172 has a sealing groove 172a formed to be coupled to the outer sealing protrusion 171a of the first sealing member 171, and an inclined surface 171c is formed on the other side of the sealing groove 172a. A contact guide 172c is formed correspondingly and inclined at a certain angle to ensure close contact.

At the center between the sealing groove 172a and the close contact guide 172c, a coupling protrusion 172b is formed to protrude toward the first sealing member 171 and is coupled to the receiving groove 171b.

The third sealing member 173 is fixed to the inner surface of the step portion 160 and is formed with a first sealing hole 173a having elasticity to be in close contact with the outer surface of the door frame 11, and the first sealing hole 173a is formed. A second sealing hole (173b) is integrally formed on one side of (173a) to seal between the door frame 11 and the step portion 160.

The first sealing hole 173a is formed in the shape of a tunnel, and the second sealing hole 173b is not shaped like a tunnel, but is formed with an extension piece 173b-1 that is open on one side and extends to a certain length.

A bent piece 173c is formed at the end of the extension piece 173b-1, and the bent piece 713c is used to connect the door frame 11 and the turning door 10 when the turning door 10 is closed. It is located in the gap between the upper surfaces 10a to maximize sealing force.
