Definitions
- the present invention relates to a device for exerting a thrust on the vertical surface of a door to achieve the opening by depressing said door.
- the present invention also relates to a method for exerting a thrust preferably of at least 50 kN on a door or other vertical flat surface from external support points.
- the invention relates to a device for achieving the opening, as quickly as possible, in force, without shock and in silence, any type of residential door, industrial premises or other.
- These devices are intended to be used mainly either by relief organizations such as fire brigade or civil protection, or by special brigades of police or gendarmerie.
- FR-2,825,354 are already known devices of this kind, which include: a hydraulic cylinder preferably, a midsole and an upper support bar, said cylinder comprising a movable rod whose end is hingedly attached, preferably removably on said midsole, and said upper support bar being hingedly attached, more preferably removably, at one end thereof to said midsole.
- the articulation of the end of the movable rod of said jack on said midsole makes it possible to arrange it in inclination preferably of 20 to 35 ° with respect to the vertical, so as to be able to exert a thrust preferably of at least 50 kN on said midsole when said midsole is pressed against said midsole door or flat vertical surface and said cylinder is supported on a lower external support point, preferably on the ground.
- the articulation of said upper support bar on said intermediate sole makes it possible to arrange said bar substantially vertically so as to be able to apply its free end directly in abutment on an upper external support point constituted preferably by the frame of said door as shown in Fig. 1A or a ceiling, or a horizontal flat surface located above said vertical planar surface.
- the term "free end” here means the end of said bar which is not fixed to said midsole.
- This device is perfectly adapted for the opening of doors opening by pushing on the side where is located the thrust device on the door, that is to say so-called “pushing" doors opening towards the inside of the door. the room from the outside of which one seeks to open it.
- the device works on pushing doors thanks to its three-level supports, namely:
- the upper end of the upper support bar abuts below and against the portion of the lintel of the door frame projecting from the vertical plane of the door surface and against which the upper end of the door comes to a stop.
- This part of the lintel located lower than the upper end of the door ensures the retention of the door in its frame, when the door is closed by pulling it.
- the so-called "pulling" doors that is to say which open by pulling towards the outside of the part outside which one seeks to open it, do not have the same configuration of the Doorframe. Indeed, on the outside of the room, there is no upper support part projecting from the door frame on which the upper end of the upper support bar could come to rest.
- the object of the present invention is to provide a new thrust device on a vertical flat surface door adapted for a pulling door, that is to say that one seeks to open the outer side, the seat belt of the frame of the door being located on the inner side.
