Abstract
Description
- 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.
- In addition to the wing, 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.
- In a two-wing door, it is necessary to make a distinction between the main wing, which is provided with an opening handle (with an anti-panic function) and is normally used to access the space, and a 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.
-
- 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.
- From the manufacturing standpoint, 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.
- Fully reversible locks are currently known for main doors which allow universality of the door on which they are fitted (said door can in fact open in either direction, depending on how it is installed).
- 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.
- Within this aim, 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.
- This aim and this and other objects that will become better apparent hereinafter are achieved by the present selvage for a secondary wing of fire doors, according to the invention that has the features set forth in
claim 1. - Further characteristics and advantages of the present invention will become better apparent from the following detailed description of a preferred but not exclusive embodiment of a selvage for a secondary wing of fire doors, illustrated by way of non-limiting example in the accompanying drawings, wherein:
-
Figure 1 is a partially sectional side view of a first embodiment of a selvage according to the invention, coupled to the corresponding lock; -
Figure 2 is a partially sectional side view of the first embodiment of a selvage according to the invention, coupled to the corresponding lock, actuated for opening; -
Figure 3 is a partially sectional side view of the first embodiment of a selvage according to the invention, proximate to the corresponding lock; -
Figure 4 is a partially sectional side view of the first embodiment of a selvage according to the invention, coupled to the corresponding lock, in which the latch releases the detent lever; -
Figure 5 is a partially sectional side view of a second embodiment of a selvage according to the invention, proximate to the corresponding lock; -
Figure 6 is a partially sectional side view of the second embodiment of a selvage according to the invention, coupled to the corresponding lock, in which the latch releases the slider locking element. - With reference to the figures, the
reference numeral 1 generally designates a selvage for a secondary wing of fire doors. - Each selvage 1 has a
front wall 2, arear wall 3, anupper 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 acentral opening 7 for the passage of thelatch 8 of thelock 9 associated with the selvage 1. - The
lateral faces 6 have tworespective 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 thelock 9 and of the selvage 1 on the fire door. - The shaft of the actuation handle inserted within the opening 10 (the upper one or the lower one, depending on the type of installation) engages in the
bit 11, which is provided with alever 12, by way of which any angular rotation of thebit 11 is transferred, in the form of a vertical translational motion, to a pair ofplates 13. - The
plates 13 have, at their central portion, a wider region 14: eachplate 13 has apusher 15 along one of the sides that delimit thewider region 14. Eachplate 13 has, at its ends, aslot 16, in which apawl 17 is engaged; said pawl is fixed on theface 6 so as to guide theplate 13 during translational motion. - The
pusher 15 is associated, by interposing adisengagement spring 18, with arespective 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 thedisengagement spring 18 has aninclined surface 20, which is faced by a threadedhole 21 inside which agrub screw 22 is screwed: the head of thegrub screw 22 rests on theinclined surface 20, allowing to adjust the protrusions of thesliders 19 from the door. - When the
sliders 19 are retracted, by way of the action of the handle, which by rotating its shaft entails a rotation of thebit 11, i.e., a translational motion of theplates 13 with a consequent movement of thepushers 15 toward the center, said sliders remain locked in said position to prevent the door from jamming in the open position due to the interference of any otherwise protruding portion of aslider 19 with the floor or ceiling. - There are various constructive solutions for locking the sliders in the retracted position.
- First of all, one might consider placing units, not shown in the figure, for locking the
slider 19 in the retracted position: each unit comprises a tubular element, in which one of thesliders 19 slides, a small spring, which is suitable to tilt the tubular element with respect to theslider 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 theslider 19. - As an alternative (as shown in
Figures 1 to 4 ), the selvage can be provided with adetent lever 23, which is interposed between theplates 13 and has anengagement tooth 24 that is forced elastically (by means of an elastic element 28) onto thering gear 25. - The
detent lever 23 has anend portion 26, which interferes with thelatch 8 of thelock 9, since thetooth 24 can move from a first configuration, in which it engages theteeth 27 of thering gear 25 by elastic forcing, to a second configuration, in which it is spaced from thering gear 25 by way of the action of thelatch 8 on theend portion 26. - Another alternative (shown in
Figures 5 and6 ) is to provide the selvage 1 with fixedpivots 29, in which thehorizontal slots 30 of alamina 31 are engaged; with an elastically yieldingstrut 32, which is arranged between therear wall 3 of the selvage 1 and the rear end of thelamina 31, and with ameans 33 for the pivoting of acarousel 34 whoseend 35 is accommodated within arecess 36 of thelamina 31. - The
carousel 34 has twolateral wings 37, each of which is pivoted to one of theplates 13; a translational motion of theplates 13 is associated with each rotation of thecarousel 34. Eachlamina 31 has aflap 38, which protrudes into the front opening 7 for accommodating the latch 8: theflap 38, and therefore thelamina 31 and theend 35 of thecarousel 34, by way of the action of thelatch 8, performs a translational motion from a first configuration, in which it rests on thefront wall 2 of the selvage 1 and thecarousel 34 is inclined with itsend 35 toward theflap 38, to a second configuration, in which it is spaced from thefront wall 2 by way of the action of thelatch 8 and in which thecarousel 34 has turned clockwise. - At least one of the
plates 13 has atoothed surface 39, which is suitable to engage detachably atooth 40 of thelamina 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. - As a consequence of the actuation of the panic bar, the
sliders 19 retract and remain retracted due to the presence of one of the three constructive solutions described above. - Their release occurs only, in the first case, when the door is arranged adjacent to the jamb, which presses the button, and in the other two cases when the
latch 8 presses respectively against theportion 26 or theflap 38. - It has thus been shown that the invention achieves the intended aim and objects.
- The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the invention as defined by the appended claims.
- All the details may further be replaced with other technically equivalent ones, without thereby abandoning the protective scope of the invention as defined by the appended claims.
- In practice, the materials used, as well as the shapes and dimensions, may be any according to requirements without thereby abandoning the protective scope of the invention as defined by the appended claims.
- Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
