Description

Door open notification and door handle / panic bar locator

The present invention relates to a door opening notification and door handle / panic bar position display device, and more specifically, to the people on the other side that the door is opened to prevent the collision and to inform the position of the door handle / panic bar An open notification and door handle / panic bar position indicator.

In general, the door is installed in the doorway when partitioning the indoor and outdoor, such as the entrance or office. Although the door has a sliding door type, there are many sliding door types that can be locked more effectively through the door lock. The sliding door is formed in a form that is rotated only in one of the interior or exterior by the hinge, the door lock is provided at a predetermined position, and the front and rear surfaces of the door is provided with an inner and outer handle coupled to the door lock.

In addition, the panic device is a push operation method of opening the door to push the push bar to open the door, it is easier to operate than the rotation operation method of opening the door by rotating the handle or lever, which is installed in the emergency or fire door of the building. .

However, when the door is open at the same time inside and outside the office, there is a problem that a person on the outside collides with the door and may be injured as the door is rotated to the outside. In particular, the visually impaired or the hearing impaired are not easily aware of the door being opened quickly, so it is more difficult to avoid collision with the door.

On the other hand, there is a sign indicating the position of the door in case the fire can not determine the position of the door in the event of a fire, but this sign is located on the upper side of the door, so the position of the door handle / panic bar Because of this, it is difficult to find the handle / panic bar of the door in a situation where the front is almost invisible by the smoke. Accordingly, there is a problem that a fire accident that is choked by the smoke to open the door and do not evacuate quickly.

The present invention is to solve the problems described above, the object of the present invention is to prevent the collision with the door that is opened by informing the person on the other side of the door, especially the disabled person to open the door handle and panic in the event of a fire The present invention provides a door opening notification and a door handle / panic bar position indicating device capable of easily visualizing the position of the bar so that the door can be opened and evacuated quickly.

At this time, since the door 1 is opened through the speaker 64, the voice flows out to be careful, so that a collision with the door 1 that is open to both the visually impaired and the hearing impaired, as well as the general public, can be easily avoided.

When the fire detection sensor 80 detects heat or smoke during a fire, the light emitting module 90 for position display is operated by the controller 70. Accordingly, as shown in FIG. 11, the position indicating LED 91 positioned outside the push bar 1002 emits light, so that the person inside the office or the like does not see the front due to the smoke. It can be found easily to open the door (1) can be quickly evacuated.

On the other hand, the position display light emitting module 90 may be operated at all times as well as during a fire.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
