A MOTOR INSTALLMENT STRUCTURE OF AUTOMATIC REVOLVING DOOR}

The present invention relates to an automatic revolving door for entry and exit, and more specifically, to enable a more beautiful and diverse implementation of the installation appearance during the initial construction of the revolving door by changing the installation position of the driving device for rotating drive of the automatic revolving door. The installation structure of the revolving door drive device.

In general, the revolving door has several doors radially installed on the rotating shaft, and each door can open and close the door according to the rotation of the shaft. It is intended to provide convenience.

In addition, the general revolving door as described above is generally installed at the center of the building entrance side of the building, and it is common to install extra swing doors on both sides of the revolving door.

This conventional manual revolving door has the inconvenience that the person must push in the door by hand. Therefore, in recent years, by installing a sensor to detect the entrance of the entrance into the rotating space by rotating the revolving door by the signal of the sensor to automatically rotate the door without the user to push the revolving door by hand to enable easy entry and exit Revolving door is developed.

1 and 2, the conventional automatic revolving door as described above, the upper and lower ends of the rotating drum (1) constituting the center of rotation is supported by the bearing (2), respectively, the peripheral edge of the rotating drum (1) Several doors 3 having the same rotation radius are installed in the door. Each of the doors 3 requires a predetermined space (hereinafter referred to as a 'rotation space') required for rotation. Then, the sensor 5 for detecting the person entering into the rotating space (S) is installed.

On the other hand, the drive motor 6 and the drum 7 are connected to the upper part of the rotating drum 1 by a chain 8 as a driving means for rotating the rotating drum 1 in response to a signal of the sensing sensor 5. It is. Therefore, when a person enters the rotating space S, the sensor 5 detects this and applies a driving signal to the driving means, so that the power of the driving motor 6 is rotated through the drum 7. The door 3 is rotated by a predetermined angle.

However, such a conventional automatic revolving door has to secure a space for mounting the drive means in the upper part of the ceiling more than a predetermined height (h), the door height is relatively low, due to these installation parts There was a problem that the construction is impossible in the nude form that can be seen inside.

The present invention has been proposed to improve the installation structure problem of the conventional revolving door drive device, the height of the door can be increased by changing the installation position of the drive devices for rotating the revolving door and the top can be constructed in nude form. The purpose is to make the exterior of the building more beautiful.

The object of the conventional automatic revolving door structure is provided with a rotating drum in which a plurality of inner doors are radially installed at regular intervals and a driving motor and a speed reducer as driving means for transmitting a rotating driving force to a rotating shaft in the rotating drum. The rotating drum is provided with upper and lower bearing parts, respectively, for supporting rotation; The drive motor and the reducer can be achieved through the drive mechanism installation structure of the automatic revolving door, characterized in that installed in the rotating drum.

Hereinafter, a detailed embodiment of the present invention will be described in detail with reference to FIGS. 3 to 5.

Figure 3 is a cross-sectional view showing the automatic revolving door drive installation state according to an embodiment of the present invention, Figures 4 and 5 shows a sectional view of the main portion and an operating state diagram for showing the folding structure of the revolving door.

First, looking at the overall configuration of the automatic revolving door according to the present embodiment, a plurality of inner doors 14 are radially fixed at regular intervals in the rotating drum 10 forming a cylindrical cylinder, the rotating drum 10 The upper and lower portions of the bearings 11 and 12 are configured to support rotation, respectively.

In addition, a driving motor 15 and a reduction gear 16 are installed in the driving housing 17 as a driving means in the rotating drum 10, and a rotational force from the reduction gear 16 is applied to the driving housing 17. Rotating shaft (13) for receiving is arranged in a coaxial axis.

In addition, the rotating shaft 13 and the rotating drum 10 are configured to be transmitted to the rotational force from the drive motor 15 by being fixed to each other by the flange 18 at the top.

On the other hand, the plurality of inner doors 14 which are radially installed are provided with folding means for allowing folding of the door alone when entering or exiting cargo or when an accident or failure occurs, which is the upper portion of each of the inner doors 14. The rotary shaft 20 protrudes from the tip, and the cam plate 24 having the settling groove 21, the curved portion 22, and the locking jaw 23 is fixed to and mounted on the rotary shaft 22.

In addition, the lower surface of the cam plate 24 is mounted to the fixing bracket 25 on the upper surface of the rotating drum 10, the operating rod 27 is mounted on the upper end of the fixed bracket 25, the rotary roller 26 at the end ), The rotary roller 26 is inserted into the settling groove 21 of the cam plate 24.

Let us look at the effect of the operation of the automatic revolving door of the present invention that constitutes such a configuration.

When a person enters and exits in the state where the automatic revolving door is installed, a detection sensor (not shown) detects the driving signal, and a driving signal is applied to the driving motor 15. The power generated from the driving motor 15 is again reduced by the reducer 16. It is transmitted to the rotating shaft 13 which is connected to the upper portion while decelerating through).

In this way, the rotational force of the rotational shaft 13 gradually rotates the rotating drum 10 which is connected by the flange 18 in the same direction, so that each of the inner doors 14, which are radially installed, is in the same direction in one direction. As it is rotated, the visitor can easily know that the access is made even without applying a separate force to push the door.

In particular, the automatic revolving door of the present invention in which the driving operation as described above is performed, since the driving means for rotating the inner door is installed inside the rotating drum 10 instead of being installed in the ceiling, the distance from the ceiling slab compared to the prior art ( H) can be greatly reduced, and accordingly the installation and construction can be designed and constructed in a nude form where the upper space can be viewed.

Therefore, when the automatic revolving door is constructed, it is possible to increase the simplicity and beauty of the exterior, and to add the beauty of the urban space and to add the interest to the visitors.

On the other hand, the inner door 14 in the present embodiment can be folded individually at the time of entering or exiting the cargo or accident or failure, which is shown in each of the inner door 14 by the artificial force as shown in FIG. When pushing in the direction of the entrance of the inside of the door 14, the cam shaft 24 is rotated at the same time while the rotary shaft 20 of each inner door 14 is rotated, wherein the cam plate 24 of the rotary shaft 20 is rotated in the direction of the entrance In this case, since the operating rod 27 and the fixing bracket 25 are rotated at the same time by the locking jaw 23 of the cam plate 24, the rotating drum 10 and all the inner doors 14 are rotated at the same time.

However, when an external force such as pushing the inner door 14 in the opposite direction rather than the advancing direction of the visitor acts, the cam plate 24 rotates in the opposite direction and the rotary roller inserted into the settling groove 21 of the cam plate 24 is rotated. Since the 26 retracts the working rod 27 along the curved portion 22, the cam plate 24 can be rotated alone, so that the rotating drum 10 is not rotated and only the inner door 14 is folded.

Therefore, the inner door 14 that is pushed in the advancing direction at the time of entry and exit is operated by the rotational force of the rotating drum 10 and simultaneously rotates all the inner doors 14 so that the same action as a normal revolving door occurs, and the opposite direction of the advancing direction of the accessor. When the inner door 14 is pushed in the direction, only the corresponding inner door 14 is folded, so that it can be seen that effective handling is possible when entering or exiting a cargo or failure or accident.

In addition, when the folded inner door 14 is to be returned to its original state, when the folded inner door 14 is rotated to its original state, the cam plate 24 on the rotating shaft 20 is rotated and the cam plate 24 is rotated. Since the rotating roller 26 of the operating rod 27 is settled in the settling groove 21, and the operating rod 27 having the rotating roller 26 is not moved by the locking jaw 23 of the cam plate 24. The cam plate 24 is no longer able to rotate, and the inner door 14 is returned to its original state.

Although the specific embodiments of the present invention have been described and illustrated in the present invention in which such an operation is made, it is obvious that the automatic revolving door structure of the present invention can be variously modified and implemented by those skilled in the art.

For example, in the above embodiment, the driving means installation structure of the automatic revolving door is provided so that the inner door can be individually folded, the drive means installation structure of the present invention is a fixed general automatic revolving door that can not be folded of the inner door It can be seen that the application is also possible.

Therefore, such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments shall fall within the appended utility model registration claims of the present invention.

As described above, the automatic revolving door of the present invention is provided with a drive means for transmitting rotational force to the inner door inside the rotating drum which is a central axis, and thus has excellent space utilization compared to the conventional ceiling mounting structure, and in particular, the appearance is simpler. It is a useful design that can be constructed in the nude form that the upper space of the revolving door has been recently spotlighted by forming the revolving door structure.
