Description

Folding automatic door using straight motion apparatus and link apparatus}

The present invention relates to a folding automatic door. More specifically, a folding automatic door using a linear movement mechanism and a linkage device, in which the transfer unit is linearly moved by the forward / reverse rotation of the motor, and the door is folded by the link unit fixed to the door and the transfer unit, respectively. It is about.

The automatic door is installed at the entrance to enter the room from the outside. Automatic door is a door is opened by a drive motor is driven when a person approaches the automatic door by a sensor to transfer the door connected to the belt (belt) or chain (chain) to one side, the door is closed after a certain time, Automatic doors such as this are of the sliding type that is installed in a lot of entrances such as large buildings.

However, the conventional sliding door type in the form of a single door is difficult to use for a wide doorway, there is a problem that the doorway waiting time is long due to the narrow entrance in a large building that many people come and go.

In the prior art Republic of Korea Utility Model (No. 20-0213329) "automatic door opening and closing device", each inner bracket 103 of the left door 101 and the right door 102, as shown in the state of automatic door opening of Figure 1 The wire rope fixing parts 105 and 106 are formed by extending a predetermined length in a direction facing the upper end of the 104 so that the inner brackets 105 and 106 are driven pulleys 107 or driven pulleys 108 when the automatic door is opened. The wire rope fixing portion 105 of the left door 101 inner bracket 103 is bent at a right angle upward and the wire rope high of the right door 102 inner bracket 104 The government 106 is bent downward at right angles so that when the automatic door is closed, the wire rope fixing portion 106 of the right side door 102, the inner bracket 104 is the wire rope fixing portion 105 of the left side door 101, the inner bracket 103 ) Inside the inner bracket (103) of the left door (101) without interference It is good.

However, the prior art as described above has a structure in which the wire rope fixing portion extending from the left door and the right door is fixed to the wire rope so that each door is simply linearly moved, and the left door and the right door enter the inside of the column when the door is opened. There is a problem that the space can be used in the building is reduced due to the automatic door is required more space.

In addition, when the size of the doorway increases, the size of the left and right doors is large, which requires a large amount of power to drive the automatic door and slows down the speed of opening and closing the door, making it difficult for users to quickly pass through the doorway. There was another problem.

In the present invention, a plurality of doors (hinges) are connected by a hinge, but the upper and lower parts of the conveying line is conveyed in a straight line by the guide rail, and the door is folded due to the link part fixed to the conveying part and the door, thus the automatic door The space occupied in this building is reduced, and its purpose is to provide a folding automatic door using a linear motion mechanism and a linkage device in which the automatic door is opened and closed quickly.

In addition, the folding structure of the door is to provide a folding automatic door using a linear motion mechanism and a linkage device that can be installed in a narrow space, such as a corridor of the building.

The present invention is a timing in which the first pulley is fixed to one side and the rotational force is generated when the power is applied, the second pulley fixed at a predetermined interval away from the first pulley, and the rotational force of the first pulley to the second pulley A folding automatic door in which a door fixed to a hinge is rotated by a drive unit provided with a belt (belt-belt), and is coupled to a support box fixed to a wall by processing in a U-shape and having a rhombus-shaped rail in the center. The upper guide rail is protruded (rail), the extension bar is fixed to the lower end of the upper guide rail and is coupled to the support box is formed, the lower guide rail formed with a roller groove in the lower inner side, and a plurality of rotating by engaging the upper and lower parts of the rail A roller fixing plate to which two rollers are fixed, a belt fixing plate fixed to an upper or lower part of the roller fixing plate, and fixed to a timing belt, and a guide bra coupled to a lower part of the roller fixing plate a guide part having a guide-bracket, a first fixed shaft inserted into the guide bracket vertically, a horizontal bar coupled to a lower end of the first fixed shaft, and a lower end of a second fixed shaft fixed to the other end of the horizontal bar. A link portion having a first pivot arm coupled to and fixed to the door, a second and third pivot arm inserted into and fixed to one side of the upper and lower sides of the door, and a rotating shaft having a lower portion fixed to the second and third pivot arms; It consists of a structure in which the upper / lower pivot is formed with a groove fixed to the upper or lower portion of the rotary shaft.

In addition, the guide bracket is fixed to the protruding groove, the first roller is inserted into the roller groove and transported there is formed a guide groove formed with a groove of a quarter circle radius.

In addition, the link part is fixed to the upper end of the first fixed shaft and inserted into the guide groove and moved along the trace, and fixed to the upper end of the second fixed shaft fixed to one side of the horizontal bar is inserted into the roller groove is linear movement The second roller is formed.

In addition, the link portion is a linear linear guide bearing along the roller groove, the guide bearing is angular movement along the guide groove is formed so that the door is folded.

In order to solve the problems as described above, the folding automatic door using the linear motion mechanism and the linkage device according to the present invention is fixed to the conveying portion, and the conveying portion and the door (door) to be transported in a straight line by the upper and lower guide rails Due to the folding of the door due to the rotating link portion, there is an effect that the building area required for the automatic door is reduced.

In addition, due to the structure of the door to be folded, it is possible to open and close quickly without a sagging door even in a large entrance, it is installed in a narrow space, such as a corridor of the building has the effect of increasing the heat efficiency of cooling / heating and control the accessor.
