Definitions

  • the present invention relates to a panic-opening device.
  • panic-opening devices are used for rapid opening of safety doors in places such as supermarkets, public offices etc.
  • the current panic-opening devices comprise a spring latch suitable for engaging a respective seat obtained on the doorpost of the safety door and a bar which is moved by the action of the user and is suitable for releasing the spring latch so as to disengage the seat and permit opening of the door.
  • said panic-opening devices are used to rapidly evacuate people from a place in the event of fire, for example. It is obvious that in the case of such an event, people crowd towards the safety door often in a state of confusion and therefore there are people who push both the bar and the door.
  • the object of the present invention consists in providing a panic-opening device which is free from the above-mentioned drawbacks, i.e. which permits rapid and effective opening of the door on which it is applied even by pushing the safety door on which the panic-opening device is installed.
  • a panic-opening device applied to a safety door comprising a first U-shaped body and having a central part with horizontal longitudinal axis parallel to the plane defined by said door and two lateral parts bent square to said central part and fixed to said door, a first of said lateral parts housing inside it a mechanism which determines closing and opening of said door, characterised in that said mechanism comprises:
  • the panic-opening device 1 comprises a U-shaped body 2 and has a central part 3 with horizontal longitudinal axis X parallel to the plane defined by the door not illustrated and two end lateral parts 4 and 5 bent square to the central part 3 and fixed to the door not illustrated by means of screws not illustrated.
  • the end part 4 has a rear wall 6 fixed to the door, two walls 7, upper and lower respectively, square to the rear wall 6 and supporting a vertical pin 8, and a lateral wall 11 defined on a plane square to the walls 7 and to the rear wall 6.
  • a mechanism 12 is installed which determines closing and opening of the door not illustrated. It should be noted that, for a better understanding of the mechanism 12, in figures 1, 2 and 3 the part 4 is drawn as if it were made of transparent material.
  • the mechanism 12 comprises:
  • the lever 27 is defined by a sheet bent in a U-shape and having:
  • the panic-opening device 1 furthermore comprises a control bar 44 supported by the central part 3 and suitable for translating due to the action of the user towards the inside of the part 3 so as to press with its appendix 45, against the action of the spring 32, the appendix 31 towards the appendix 23 thus determining rotation of the lever 27 and permitting opening of the safety door.
  • a pin 46 originates from the bar 15 in the direction of the bar 13 but without coming into contact with it; said pin is suitable for coming into contact in a certain operating position of the lever 27 with a section 47 of the second lateral wall 33 of the lever 27.
  • a further pin 48 is installed parallel to the pin 8 and suitable for constituting the stroke end to rotation of the lever 27 around the pin 8 since the lower face of the appendix 31 or a section 49 (figure 8) of the walls 33 can rest against the same.
  • Figure 4 illustrates the mechanism 12 with the safety door closed.
  • Figures 2 and 5 illustrate the mechanism 12 with the safety door closed but with the control bar 44 pushed towards the inside of the central part 3.
  • the spring latch 14 By pushing the control bar 44 again or the door itself, the spring latch 14, being free in its movement apart from the counter force of the spring 24 and having a wedge-shaped head, due to the contact that occurs between said head of the spring latch 14 and the walls of the seat 29 which are also triangular-shaped, retracts inside the part 4 causing opening of the safety door.
  • Figure 7 illustrates the mechanism 12 with the door open.
  • a panic-opening device is provided unlike the devices currently on the market in which, to open the door, a force must be applied to a lever which mechanically determines translation of the main spring latch.
  • the pressure on the control bar 44 determines only release of the translation of the spring latch 14 and not its translation. Basically, by pushing the control bar 44 the lever 27 is released from the spring latch 14 so that a further pressure on the control bar 44 or on the door itself determines the opening thereof. It is evident that to open a safety door with the panic-opening device subject of the present invention a reduced force applied on the control bar 44 is sufficient. It should be underlined that the mechanism 12 is simple to produce and, above all, increases the safety level of the door.
