Definitions
- the present invention relates to a selvage for a secondary wing of fire doors.
- Fire prevention regulations are designed to prevent the occurrence of fires, contain their expansion and stop their reaction by way of rapid extinguishing actions. Accordingly, prevention includes protection activities aimed at containing the effects of the energies released by a fire in space and time by reducing the rate of flame propagation and extending the period of ignition induction.
- Fire doors are within this field; in fact they must: divide contiguous spaces and prevent the passage of fire and superheated gases from the space at risk to the adjacent space; prevent the propagation of the fire also by heat irradiation, i.e., have a sufficient thermal insulation capacity; allow, even during the fire, the escape of individuals who have remained in the space where the fire has developed, and accordingly always open easily at least in the intended direction; after opening, fire doors must close automatically from any position, therefore even from the fully open position at 180°, in order to rapidly prevent fire propagation; and fire doors must be installed with a preset "direction of escape" from the space at risk toward the outside or toward lower-risk spaces.
- the details become particularly important, such as for example the panic bars that ensure opening by simply pushing on said bar and ensure escape from the premises where the fire has developed.
- main wing which is provided with an opening handle (with an anti-panic function) and is normally used to access the space
- secondary wing which is provided with a panic bar and is usually closed.
- the secondary wing is provided with the selvage associated with the latch that is present in the lock of the main wing.
- the document EP 0 849 425 describes a selvage for a secondary wing of a two-wing fire door according to the preamble of claim 1.
- Fire doors are installed so as to ensure escape from the space that is exposed to the highest risk of fire toward the space at lower risk: for this reason, both the main door and the secondary door can be installed according to the two different possible opening directions, depending on the installation characteristics.
- the disadvantage linked to this solution is the need to manufacture two different products in order to perform the task of allowing escape in the two possible directions.
- a door lock with a symmetrical locking configuration is known, for example, from CH 403541 .
- the aim of the present invention is to obviate the above-cited drawbacks and meet the mentioned requirements, by providing a selvage for a secondary wing of fire doors that is totally reversible, so as to ensure universality of installation of the door on which it is fitted.
- an object of the present invention is to provide a selvage that is simple, relatively easy to provide in practice, safe in use, effective in operation, and has a relatively low cost.
- the reference numeral 1 generally designates a selvage for a secondary wing of fire doors.
- Each selvage 1 has a front wall 2, a rear wall 3, an upper wall 4 and a lower wall 5: the four walls that are defined are delimited between two lateral faces 6 (only one of which is shown in the figure).
- the front wall 2 has a central opening 7 for the passage of the latch 8 of the lock 9 associated with the selvage 1.
- the lateral faces 6 have two respective openings 10, which are arranged symmetrically with respect to the centerline of the selvage 1 and in which the shaft of the actuation handle can engage.
- the handle must be installed on the selvage 1 so that it is aligned with the handle fitted to the lock 9: the choice is therefore dictated by the type of installation of the lock 9 and of the selvage 1 on the fire door.
- the shaft of the actuation handle inserted within the opening 10 engages in the bit 11, which is provided with a lever 12, by way of which any angular rotation of the bit 11 is transferred, in the form of a vertical translational motion, to a pair of plates 13.
- each plate 13 has a pusher 15 along one of the sides that delimit the wider region 14.
- Each plate 13 has, at its ends, a slot 16, in which a pawl 17 is engaged; said pawl is fixed on the face 6 so as to guide the plate 13 during translational motion.
- the pusher 15 is associated, by interposing a disengagement spring 18, with a respective slider 19, which can slide axially within appropriately provided receptacles of the door and whose end is suitable to engage in a receptacle of the threshold or lintel (depending on the direction of installation of the selvage 1).
- the portion of the slider 19 that makes contact with the disengagement spring 18 has an inclined surface 20, which is faced by a threaded hole 21 inside which a grub screw 22 is screwed: the head of the grub screw 22 rests on the inclined surface 20, allowing to adjust the protrusions of the sliders 19 from the door.
- each unit comprises a tubular element, in which one of the sliders 19 slides, a small spring, which is suitable to tilt the tubular element with respect to the slider 19, blocking its sliding, and a button, whose retraction, following the contact of the door with the lintel or threshold, disengages the small spring from the tubular element, releasing the slider 19.
- the selvage can be provided with a detent lever 23, which is interposed between the plates 13 and has an engagement tooth 24 that is forced elastically (by means of an elastic element 28) onto the ring gear 25.
- the detent lever 23 has an end portion 26, which interferes with the latch 8 of the lock 9, since the tooth 24 can move from a first configuration, in which it engages the teeth 27 of the ring gear 25 by elastic forcing, to a second configuration, in which it is spaced from the ring gear 25 by way of the action of the latch 8 on the end portion 26.
- FIG. 5 and 6 Another alternative (shown in Figures 5 and 6 ) is to provide the selvage 1 with fixed pivots 29, in which the horizontal slots 30 of a lamina 31 are engaged; with an elastically yielding strut 32, which is arranged between the rear wall 3 of the selvage 1 and the rear end of the lamina 31, and with a means 33 for the pivoting of a carousel 34 whose end 35 is accommodated within a recess 36 of the lamina 31.
- the carousel 34 has two lateral wings 37, each of which is pivoted to one of the plates 13; a translational motion of the plates 13 is associated with each rotation of the carousel 34.
- Each lamina 31 has a flap 38, which protrudes into the front opening 7 for accommodating the latch 8: the flap 38, and therefore the lamina 31 and the end 35 of the carousel 34, by way of the action of the latch 8, performs a translational motion from a first configuration, in which it rests on the front wall 2 of the selvage 1 and the carousel 34 is inclined with its end 35 toward the flap 38, to a second configuration, in which it is spaced from the front wall 2 by way of the action of the latch 8 and in which the carousel 34 has turned clockwise.
- At least one of the plates 13 has a toothed surface 39, which is suitable to engage detachably a tooth 40 of the lamina 31.
- the operation of the invention is as follows: since the selvage 1 is completely symmetrical, it can be fitted both on a door that turns clockwise when pushed and on a door that turns counterclockwise when pushed.
- the different installation depends exclusively on how the selvage 1 is orientated, and is provided so that the panic bar is at the same height as the handle provided on the door that is coupled to it and on which the lock 9 is fitted.
- the sliders 19 retract and remain retracted due to the presence of one of the three constructive solutions described above.
