Description

Industrial Safety Door Having Structure Allowing Simultaneous Access For Two People}

The present invention relates to an industrial safety entrance door, and more specifically, to an industrial safety entrance door that is installed at an industrial site and includes a configuration that can dramatically reduce the probability of a safety accident occurring by allowing two or more people to enter the site at the same time.

There are factories or sites that require two or more people to form a group for the purpose of significantly reducing the risk of safety accidents when performing work in the factory or field.

Specifically, in addition to the purpose of preventing safety accidents in advance, the purpose of solving the problem of not being able to respond quickly when a safety accident occurs by one person is to form a group of two or more people to work.

As a rule, if two or more people form a group and perform work, even if a safety accident occurs, another worker in the same group can respond quickly, preventing the scale of the safety accident from increasing.

Although most employers and workers are aware of the risk of safety accidents related to one-person work, they often enter the work site and perform work without considering safety for work efficiency.

If an accident occurs while one person is performing a task, such as a stuck accident or a fall accident, in which the worker cannot escape on his or her own, the scale of the accident can gradually increase if there are no witnesses or nearby workers, and in extreme cases, it can result in the death of the worker. there is.

To solve this problem, as shown in Figure 1, a locking device is installed on the door, and access is controlled by the manager.

However, the door according to the prior art has a problem in that it requires a relatively long time and manpower to open and close as it is a heavy structure. In addition, the door according to the prior art has the problem of requiring a separate manager for access control.

Therefore, there is a need for a technology that can solve the problems caused by the prior art mentioned above.
