Definitions

  • the present invention relates to the technical field of doors and windows frames, and particularly concerns a safety door or window frame structure that is especially suitable to simplify the maintenance works of the door or window frame.
  • the invention further concerns a door or window frame and a profile for manufacturing such a door or window frame structure.
  • Safety door or window frames are known in the art, in particular safety door or window frames of the fire-resistant type or the like, which comprise a frame made of a plurality of internally hollow metallic profiles, reciprocally connected to one another.
  • the expansion of the intumescent layer is independent from the user's will, and takes place only in case of fire. Further, in this known solution the layer of intumescent material is fixed inside the profile and cannot be replaced.
  • Safety door or window frames are also known, which generally comprise a mechanic safety lock which includes locking metallic bars vertically movable by a user between a working position where they are engaged with a stationary support to prevent the opening of the door or window frame and a rest position where the door or window frame can be freely opened.
  • the engagement of the metallic bars with the stationary support takes place by holes manufactured into the support that suitably house the ends of the bars.
  • the bars In the working position, the bars extend outwardly from the door or window frame so as to engage the holes, whereas in the rest position they are retracted within the frame.
  • a main object of this invention is to overcome, at least partly, the above drawbacks, by providing a door or window frame structure which is highly efficient and relatively cost-effective.
  • Another object of the invention is to simplify the maintenance of the safety lock of a safety door or window frame structure, particularly of the fire-resistant type or the like.
  • Another object of the invention is to minimize the maintenance costs and time for the safety door or window frame structure.
  • Another object of the invention is to provide a door or window frame structure having a particular aesthetic appeal.
  • a safety door or window frame structure particularly of the fire-resistant type or the like, as defined in claim 1.
  • a metal frame is provided for manufacturing a safety door or window frame structure, particularly of the fire-resistant type or the like, as defined in claim 14.
  • a metal profile is provided for manufactuirng a safety door or window frame structure, particularly of the fire-resistant type or the like, as defined in claim 15.
  • safety door or window frame structure and the like is intended to indicate a door or window frame structure, for example a door, a gate or a window, which is fire-resistant, flame trap, smoke barrier and/or emergency door or window, or door or window frame structures placed on the escape way according to specific law rules.
  • the metal profile 1 which may be made for instance of steel, is particularly suitable for manufacturing a safety door or window frame structure 100, such as for example a door or a window, particularly of the fire-resistant type or the like.
  • the safety door or window frame structure 100 may be operatively connectable to a stationary support, which may be a wall M, a floor B, a door frame T' and/or a secondary frame C, or a combination of two or more thereof.
  • a stationary support which may be a wall M, a floor B, a door frame T' and/or a secondary frame C, or a combination of two or more thereof.
  • the safety door or window frame structure 100 may include a shutter frame T connected to a door frame T', which may be fixed by means of fixing screws V to a secondary frame C, that is housed in the wall M.
  • the door or window frame structure 100 may be fixed to the wall M by means of the door frame T' and the secondary frame C.
  • the shutter frame T may be provided with glass fastener F 1 , F 2 for the installation of a glass plate G, and may be connected to the door frame T' by means of hinges R.
  • Every frame T, T' may be manufactured with a plurality of internally hollow metal profiles connected to one another, for example by welding.
  • the embodiment of the profile 1 illustrated in FIGS. 2 and 3 results particularly advantageous upon connection by welding of the different profiles, as hereafter illustrated.
  • the door or window frame structure 100 may include a safety lock L.
  • the locks of this type may generally have several locking points, for example central, up and down locking points, or up and down locking points.
  • the safety lock L of the door or window frame structure 100 according to the invention may be of the substantially mechanical type, and in particular it does not include any intumescent seal.
  • the lock L may comprise a couple of locking metal bars A, defining a longitudinal axis X.
  • the bars A may be selectively actionable by a user, for instance by means of a key or similar members, so as to slide along the axis X between a working position, illustrated in FIG. 5 , and a rest position, illustrated in FIG. 6 .
  • the bars A may extends outwardly from the door or window frame structure 100 to engage a corresponding hole H manufactured into a stationary support, which may be a wall M or the door frame T' or the secondary frame C. This way, the incidentally unintentional opening of the door or window frame structure 100 will be prevented.
  • the bars A may be retracted within the door or window frame 100, so that the door or window frame 100 can be freely opened.
  • the door or window frame structure 100 may include a frame T manufactured by a plurality of profiles 1.
  • the profile 1 includes, respectively consists of, an internally hollow elongated element 2, which defines a longitudinal axis Y.
  • the elongated element 2 includes one couple of outer walls 3, 4 substantially parallel to one another and designed to define the faces of the door or window frame exposed at sight during use.
  • a couple of glass fastener F 1 , F 2 may be coupled in a per se known manner to the elongated element 2.
  • the elongated element 2 has, for its whole length, a substantially U-shaped section, so as to define a longitudinal compartment 5.
  • This compartment may have two substantially parallel facing side walls 6, 7 connected to one another by an end wall 8, which defines the bottom of the U-shaped section.
  • the side walls 6, 7 of the compartment 5 may respectively face the outer walls 3, 4 of the elongated element 2.
  • the end wall 8 of the compartment 5 may be substantially perpendicular to the side walls 6, 7.
  • the longitudinal compartment 5 may have dimensions sufficient to removably house at least the vertical bars A of the lock L during the use. When the vertical bars A of the lock L are housed into the longitudinal compartment 5, the two longitudinal axis X and Y are substantially parallel.
  • the bars A are easily accessible by an operator, for example for maintenance or replacement.
  • the longitudinal compartment 5 may house the lock L and, in general, the whole inner mechanisms of the locking devices of the door, for instance the mechanisms of an antipanic pushbar, so as to facilitate to the utmost the maintenance and substitution work of the operator.
  • a further advantage of the invention consists in the fact that all fixing screws V of the frame T' to the secondary frame C, which is embedded into the wall M, are hidden to the user's sight, as they are inserted through the longitudinal compartment 5. This increases the aesthetic appeal of the door or window frame.
  • at least one cover element 13 of the longitudinal compartment 5 may be provided.
  • the bars A which may have generally cylindrical shape, may have a diameter comprised between 5 and 15 mm.
  • the longitudinal compartment 5 may have a minimum width L 1 of 8 mm, and even more preferably a minimum width of 10 mm.
  • the width L 1 may be comprised between 10 mm and 20 mm.
  • the longitudinal compartment 5 may have a minimum depth P of 10 mm, preferably of 25 mm, and even more preferably a minimum depth P of 35 mm.
  • the depth P may be comprised between 10 mm and 50 mm.
  • the elongated element 2 may be manufactured starting from a metal plate, with a minimum thickness S of 1,3 mm.
  • the thickness S may be maximum 2,0 mm, so as to facilitate the bending of the plates for forming the frames T, T'.
  • the thickness S may be close to 1,8 mm.
  • the distance D between the walls 3, 4 of the elongated element 2 may be not greater than 90 mm, so as to facilitate the rotation movement of the shutters of the door or window frame and to allow the best opening and closing action thereof.
  • At least one between the outer walls 3, 4 may have a total length L 2 , possibly with the glass fasting element F 2 , not greater than 100 mm.
  • the elongated element 2 may comprise insulating means interposed therebetween.
  • the insulating means may comprise a first plurality of passing through apertures 9, preferably having the shape of elongated slots, manufactured through the end wall 8.
  • a second plurality of apertures 10 may be manufactured through the back wall 11 which connects the walls 3, 4, so as to face the first plurality of apertures 9.
  • the back wall 11 faces the end wall 8 and the front walls 15, 16 which connect the walls 3, 4 with the side walls 6, 7 of the longitudinal wall 5.
  • the insulating means may comprise, as an alternative or in combination with the apertures 9 and possibly the apertures 10, at least one layer 12 of insulating material coupled to the end wall 8 and to the side walls 6, 7.
  • the layer 12 of insulating material may be configured so as to be spaced apart from both the outer walls 3, 4, in such a manner to increase the heat transport resistance therebetween because of the presence of the air gap.
  • the absence of insulating material in contact with the outer walls 3, 4 allows a better reciprocal welding of the profiles 1.
  • the welding operations may be carried out exclusively in correspondence of the outer walls 3, 4, i.e. far from the insulating material.
  • the welding temperatures may be lower with respect to the prior art, and it will be possible to avoid damages to the insulating material during the welding.
  • the several welding operations may be carried out with the insulating material already placed into the profile, which greatly simplify the assembly operations of the frame.
  • the insulating material may be chosen in the group constituted by mineral wools, preferably rock or glass wool, materials based on thermosetting polymers, such as furanic, phenolic or polyuretanic resins, also in the form of foams, materials based on thermoplastic polymers, such as polyphenilether, polyetheretherketone, polyolefins, materials based on inorganic silicates, also in aerogel form, intumescent compositions having polymeric or inorganic base, possibly with expanding graphite.
