Definitions

  • the present invention relates to a removable thrust device for the opening by pushing of a door, capable of exerting a thrust on the vertical surface of the door and its pushing.
  • the present invention also relates to a method for exerting a thrust preferably of at least 50 kN on a door or any other vertical flat surface from external support points.
  • the invention relates to a device for opening, as quickly as possible from a set of at least 3 parts ready to be assembled, by force, without shock and in silence, any type of door for a home, industrial premises or other.
  • a device for exerting a thrust on the vertical surface of a door to effect the opening by pushing said door is perfectly adapted for the opening of doors opening by pushing or pulling, from the face of said door where the thrust or pull on said door must be exerted to open it.
  • These devices operate by pushing on the door thanks to supports at three levels, namely on the ground, on the central part of the door panel, where the door is pushed, and on the upper part or lintels of the door retaining and stop frame, where the direct thrust by a jack is exerted.
  • the articulation of the end of the movable rod of said jack on said intermediate sole plate allows it to be arranged at an inclination preferably of 20 to 35° relative to the vertical, so as to be able to exert a thrust preferably of at least 50 kN on said intermediate sole plate when said intermediate sole plate is applied in support on said door or vertical flat surface and said jack is in support on a lower external support point, preferably on the ground.
  • the articulation of said upper support bar on said intermediate sole plate makes it possible to arrange said bar substantially vertically so as to be able to apply its free end directly in support on an upper external support point preferably constituted by the frame of said door or a ceiling, or a horizontal flat surface located above said vertical flat surface.
  • the term "free end” means the end of said bar which is not fixed to said intermediate sole plate.
  • the device of FR 2 825 354 is perfectly suited for opening doors that open by pushing on the side where the push device is located on the door, i.e. so-called doors “push” doors opening towards the inside of the room from the outside of which it is sought to be opened.
  • the device works on push doors thanks to its supports at three levels, namely: on the ground, on the door and, on the upper part or lintel of the retaining and stop frame of the door.
  • the upper end of the upper support bar abuts below and against the part 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 abuts.
  • This part of the lintel located lower than the upper end of the door in fact ensures that the door is held in its frame when the door is closed by pulling it.
  • FR 2 944 709 provides a pushing device on a door with a vertical flat surface adapted for a pulling door, that is to say that one seeks to open from the outside, the retaining belt of the door frame being located on the inside.
  • This device for opening by pushing a door capable of exerting a push on the vertical surface of the door and its pushing, when the device is positioned against the door on the side where it opens by pulling it, comprises an upper support device fixed in an articulated manner, preferably in a removable manner, to the upper end of said upper support bar, said upper support device comprising at least one wedging and blocking part capable of allowing the rotational articulation of said wedging and blocking part relative to the upper end of said upper support bar.
  • Said wedging and blocking device thus fulfils the same technical effect as the part of the lintel projecting from the vertical plane of the door serving as a stop, in a door opening device without this blocking and wedging device at the upper end of the upper support bar, when the door opening device is located on the side where the door opens by pushing.
  • the jack is intended to rest on the ground, but could also rest on a lower external support point.
  • the intermediate sole is intended to rest on the door, but could rest on a median external support point.
  • articulatedly means that the two parts fixed to each other can pivot relative to each other at least around a horizontal axis when the longitudinal directions of said lower support bar and upper support bar are located in the same vertical plane.
  • thrust devices are known from GB 2 236 803 A , WO 2010/125263 A1 And FR 2 983 736 A1 .
  • the devices described in these known documents are not optimally suited for easy transport and implementation, in particular because the upper support bar and lower support bar are each in one piece and therefore of a relatively long length.
  • the device In its current configuration, the device is bulky, complicated to carry, particularly during interventions on the upper floors of a building, leading to risks of impact on the walls and the stairwell railings, and not easy to put in place on the door or remove after implementation.
  • This bulkiness also affects its packaging and transport for carrying over long distances, because currently the device can only be separated into two very long elements comprising (a) the lower support bar with the jack and the lower sole and (b) the upper support bar with the intermediate sole and the upper support device.
  • the aim of the present invention is to provide a device that overcomes these drawbacks.
  • the present invention provides a door opening device that can be dismantled into at least 3 parts. manually and without any tools, which allows easier carrying because it can be shared between several people if necessary, and without the risk of shock in stairwells when carrying up and down the floors of a building, and finally it can be assembled in a few seconds on the door concerned. It can also be packaged in a much smaller carrying case than the one currently used, which can be carried by a single person.
  • the present invention provides a door opening push device that can be mounted from a ready-to-assemble assembly of at least 3 parts by reversible fixing devices that can be activated and deactivated manually, and capable of maintaining in rectilinear alignment lower and upper parts of the lower and upper support bars.
  • the present invention provides a pushing device for exerting a push on a door or any other vertical flat surface such as a partition, comprising a lower support bar, an intermediate support sole and an upper support bar, and preferably a lower support sole, each of said lower support bar and respectively upper support bar being capable of being actuated in telescopic extension in which the pushing device is capable of being assembled from a ready-to-assemble assembly of at least 3 parts comprising two reversible fixing devices which can be activated and deactivated manually, capable of carrying out the reversible fixing of the lower and upper parts of each of said lower support bar and respectively upper support bar and capable of maintaining said lower support bar and upper support bar in rectilinear alignment when they are actuated in said telescopic extension.
  • varying the distance between said lower part and upper part of the upper support bar means that it is a question of varying the ends of said lower part and upper part of the upper support bar fixed or capable of being fixed on said intermediate sole and respectively said upper support sole, and by "fixed in an articulated manner in rotation on said sole fixed in an articulated manner in rotation on and relative to said sole..”, that it is a articulation in rotation relative to said sole concerned.
  • said first fixing device comprises an upper end portion of said first cylinder rod capable of cooperating and being reversibly fixed to a complementary lower end portion of said upper portion of the lower support bar.
  • said first fixing device comprises a said upper end portion of said first cylinder rod of male shape, preferably outside said cylinder body when said first cylinder rod is in the retracted position, capable of engaging and being fixed reversibly in a said complementary lower end portion of female shape such as a first cavity of said upper portion of the lower support bar.
  • said upper terminal part of the first cylinder rod and said first cavity are of shapes complementary cylindrical rods capable of fitting into each other to activate said first fixing device and deactivate it under manual control, and of the same length d1 sufficient to maintain said rectilinear alignment, preferably of smaller diameter than that of said first cylinder rod.
  • said first fixing device comprises an upper end portion of said first cylinder rod in the form of a cavity capable of receiving and being reversibly fixed to a said lower end portion of complementary male shape of said upper portion of the lower support bar.
  • said first cylinder rod comprises two telescopic elements. It is understood that said upper end portion of the first cylinder rod is at the end of the rod element furthest from the cylinder body when the cylinder rod is extended.
  • This embodiment is advantageous because it allows the cylinder body to be of shorter length while being able to receive the cylinder rod retracted inside the cylinder body and offers safety with regard to the risk of buckling of the cylinder rod when the thrust device is implemented.
  • said second fixing device comprises an upper end portion of said second rod capable of cooperating and being reversibly fixed to a complementary lower end portion of said upper portion of the upper support bar.
  • said second fixing device comprises a said upper terminal part of said second rod, preferably of smaller diameter than that of said second rod, capable of engaging and being fixed reversibly in a second cavity at the lower end of said upper portion of the upper support bar.
  • said upper terminal part of the second rod and said second cavity are of complementary cylindrical shape capable of entering into one another to activate said second fixing device and deactivate it under manual control and of the same length d2 sufficient to maintain said rectilinear alignment.
  • said second fixing device comprises a said upper end portion of said second rod in the form of a cavity capable of receiving and being reversibly fixed to a complementary male end portion at the lower end of said upper portion of the upper support bar.
  • said second rod comprises a thread which is capable of cooperating with a peripheral wheel crossed by said second rod such that the manual rotation of said wheel causes said relative sliding of said second rod relative to said lower part of the upper support bar.
  • said upper support device is fixed in an articulated manner, preferably removably, to the upper end of said upper support bar, said upper support device comprising at least one wedging and blocking part capable of allowing the opening of a pull door.
  • At least one of said lower sole and intermediate sole comprises a flat support, one face of which is intended to come to bear on the ground or respectively said door or vertical flat surface, comprising non-slip elements, preferably hard points, and the other face of which comprises articulation means on which articulated fixing means are fixed.
