Description

Folding part locking device of large revolving door using wind pressure {APPARATUS TO LOCK THE FOLDING PART OF SWING DOOR TO USE THE WIND PRESSURE}

The present invention relates to a folding part locking device of a large revolving door using wind pressure, and in particular, the wing door hinged to the showcase door can be locked or released automatically according to the strength of the wind blowing from the outside for convenience, stability and It relates to a folding unit locking device of a large revolving door using the wind pressure to improve the durability.

In general, a large revolving door is composed of a cylindrical glass wall with four (or three) doors attached to a central rotating shaft or a showcase and enclosing the outside of the revolving door. When a pedestrian approaches, the top sensor detects or rotates automatically by the user pressing the push button, so the user can pass comfortably without the inconvenience of pushing the door by hand. In addition, large revolving doors (e.g., 3.6M or more in diameter) are larger than existing revolving doors (e.g., 3M or less in diameter) and have more space between the doors. You can pass through things you could not afford, and you can pass uncomplicated during rush hours or when many people are crowded at once.

In addition, even if people and luggage pass through, the door is not opened and the revolving door always acts as a partition between the outdoors and indoors to achieve windproof, dustproof, soundproofed, and warmth effects, keeping the inside air comfortable, and cooling / heating energy loss. This can reduce waste of air conditioning costs.

And the door of the revolving door is made of a swing door (swing door) type hinged to the showcase door so as to be folded when the user touches or pulls. Therefore, the revolving door is folded when the user's moving speed is slow and the wing door is contacted with the user, and when the user falls from the wing door, the revolving door is returned to its original position by the restoring mechanism so that it can pass safely. You can fold doors when you need them and when you need them, for example, to carry your luggage.

However, conventionally, the door is easy to swing even with light force, so even when the wind blows a little, the wind does not act as a windshield, and the gap is opened between the door and the wall, thereby eliminating airtightness. There was a problem falling. In addition, when the wind is strong, the door is severely shaken, which not only threatens the safety of passers-by, but also causes a problem of deterioration in durability.

In order to solve such a problem, conventionally, a switch operated by a manual operation is attached to one side of the revolving door, and when the wind is blowing, the wing door is locked so that the wing door is not folded by the manager such as the water level and the doorman. If it is weakened, the wing door can be folded back by pressing the switch again, but it is inconvenient to manage because it must be locked and released by manipulating the switch, and it is difficult to accurately detect the strength and weakness of the wind. There is a defect that it is impossible to properly perform the release operation when necessary, and because the manager should always wait and pay attention to the management of the revolving door, there is a problem that not only management is difficult but also waste of manpower.

The present invention was devised to solve such a conventional problem and defects, and it automatically locks or releases the wing door hinged to the showcase door in accordance with the strength of the wind blowing from the outside for convenience and stability in use. And to provide a folding unit locking device of a large revolving door using the wind pressure to improve the durability.

Referring to the operation of the present invention as described above are as follows.

First, the operation according to the entrance and exit of the revolving door that is the device of the present invention is briefly examined, the revolving door employing the folding part locking device of the large revolving door using the wind pressure according to the present invention is the sensor when the user approaches the Since the showcase door 11 and the wing door 12 are rotated together by sensing, the user can easily enter and exit.

And, while the entrance and exit using the automatically rotating rotary door 10, for example, when the elderly, children and people unfamiliar with the use of the slow moving and the rotary door 10 is rotated faster the wing door 12 ) Is in contact with the user's body, and when the showcase door 11 and the wing door 12 is manufactured in a fixed form, the user hits the wing door 12 while being hurt and injured or inconvenient to use. As mentioned above, since the showcase door 11 and the wing door 12 are hinged to be foldable, the wing door 12 is folded back while being in contact with the user's body. Thus, the user can move safely without being hit.

And, users can fold the wing door 12 as needed, and enter and exit conveniently.

Wing door 12 of the revolving door 10 as described above is foldably coupled to the showcase door 11 has the advantage of allowing the user to enter and exit safely and conveniently, while the wind is blown by the wind flowing from the outside As shown in phantom 2, the noise is not only generated while shaking back and forth, but also has the disadvantage of inconvenient user access. This disadvantage is that the wing door 12 of the revolving door 10 is designed according to the present invention. It is eliminated by automatically locking and releasing by the folding part locking device.

The folding part locking device of the large revolving door using the wind pressure of the present invention, when the wind flowing from the outside flows into the vent 31 of the wind pressure detecting means 30, the rotary blade coupled to the shaft 33 of the encoder 32 Since the 34 is rotated in proportion to the wind pressure, the encoder 32 detects a change in the wind pressure flowing therein, and the detection signal is input to a controller for controlling the operation of the electromagnetic brake 46 so that the controller controls the electromagnetic brake. By operating (46) on and off depending on the degree of wind pressure, the adverse effect of the wind pressure is eliminated.

That is, the encoder 32 detects the wind pressure acting on the vent 31 of the wind pressure detecting means 30, so that power is not input to the power line 47 when the detected wind pressure is less than or equal to the set value. In this case, the electromagnetic brake 46 does not operate, and thus the brake gear 43 is not braked. In this case, the brake gear 43, the idler gear 45 and the door gear 44 which are engaged with each other may rotate. Thus, the wing door 12 hinged to the showcase door 11 can be folded freely.

When the wind pressure is greater than or equal to the set value, as the power is input to the power line 47 under the control of the controller, the armature 48 of the electromagnetic brake 46 protrudes to stop the brake gear 43 from rotating. The engaged idler gear 45 and the door gear 44 are prevented from rotating, which causes the wing door 12 to lock and prevent rotation.

Therefore, the wing door 12 of the revolving door 10 is freely folded when the wind pressure is less than the set value to ensure the safe entrance of the user, when the wind pressure is more than the set value is locked so as not to be folded, the wing door ( Problems such as noise and discomfort caused by the fluctuation of 12) can be solved.

The present invention as described above is configured to automatically lock or release the wing door hinged rotatably to the showcase door by measuring the wind pressure in accordance with the wind pressure, so that the wing door in case of severe wind blowing By eliminating the problem of swinging back and forth by the wind, it can be used more conveniently and safely, there is an advantage that can prevent the problem of falling durability as well as noise generated by the wing door is shaken by the wind.

Therefore, the present invention can improve the convenience, safety and reliability of the use of the revolving door, there is an effect that can prevent the waste of manpower and extend the service life.
