Description
- The present invention basically relates to a manually operated mechanical device designed to release the swinging leaves of gates or doors motor-driven by the corresponding actuators, for example, of the arm type (both electromechanical ones and oleodynamic ones). The purpose of this is to enable ease of manual movement thereof, without the need for any particular effort and in emergency situations (for example, due to the absence of electrical supply or failure of the equipment), by persons that come to find themselves on the wrong side of the door, either closed in or closed out.
- Currently, the leaves of gates and doors with swinging leaves, which will be referred to hereinafter for convenience as "doors", can be motor-driven so as to control remote opening or closing thereof without having to carry out manual opening thereof. Amongst the types of actuators most widely used for this purpose are the so-called "arm" actuators.
- This type of actuator is fixed, via an appropriate articulation, at one end to the swinging leaf, whilst the other end is fixed to the doorpost. The electrically supplied arm actuator increases or reduces its length like a telescopic rod thus impressing the movement of opening or closing on the leaf.
- The arm actuators produced by the various manufacturers are equipped with an emergency release device that enables manual opening of the door in the case of breakdown or absence of electrical supply to prevent the danger of getting trapped inside by persons that have to use the door as exit from buildings, garages, ramps, etc.
-
FR 2 469 543 A1EP 0 748 916 A1 disclose actuators of this type. - The pushing or pulling force to be impressed upon the leaf to obtain opening thereof by persons can, however, become excessive in unfavourable situations where the ratio between the length of the leaf and that of the actuator is excessively low (approaching unity, i.e., with actuator and leaf of same length).
- This is due to the fact that in order to open the leaf of the door the actuator must necessarily be shortened or lengthened in a telescopic way (according to the mechanism adopted), but opposing this movement is the internal friction of the actuator (and viscosity of the hydraulic oil in the case of oleodynamic actuators).
- In addition, said release devices, on board the actuators, in general:
- are not immediate and simple to manoeuvre;
- are not accessible from outside with the door completely closed and panelled, thus not enabling the manual manoeuvre of emergency when entering.
- Consequently, a first purpose of the present invention is to provide a solution for enabling manual operation, in cases of emergency, of the motor-driven leaves of doors with an effort comparable to the one necessary to move said leaves in the absence of the actuators.
- A second purpose of the invention is to cause passage from motor-driven operation to manual operation to occur by means of a simple and immediate manoeuvre of a push or pull type by means of a knob in a way similar to the manoeuvre that would be made on said leaf if it were operated manually.
- A third purpose of the invention is to cause the aforesaid manoeuvre to be made (where necessary) both from inside and from outside.
- A fourth purpose of the invention is to be able to restore easily the normal automatic operation of opening/closing of the door.
- A fifth purpose of the invention is to enable installation of the device also on automatic opening systems already installed without having to make any substantial modifications to the system itself.
- The above and other purposes have been achieved, according to the invention, by providing a device as defined by
claim 1. - A better understanding of the invention will be obtained from the ensuing detailed description and with reference to the attached drawings, which illustrate, purely by way of non-limiting example, a preferred embodiment.
- In the drawings:
-
Figure 1 is a top plan view of a motor-driven leaf of a known type, with an arm directly fixed to the swinging leaf; -
Figure 2 is a 3D view that shows the invention from the inside of the swinging leaf, where the actuator is located; -
Figure 3 is a 3D view that shows the invention from the outside of the swinging leaf; -
Figure 4 , which is similar toFigure 1 , shows the device according to the present invention installed between the attachment of the actuator and the leaf in a system of a known type; -
Figure 5 is a vertical section of the invention, in a position corresponding to the bolt for blocking/releasing the leaf with respect to the actuator; -
Figure 6 is a horizontal section, according to the plane of trace X-X indicated inFigure 5 , of the blocking/releasing bolt; -
Figure 7 , which is similar toFigure 4 , shows manual opening of the leaf after actuation of the releasing bolt according to the present invention; and -
Figure 8 , which is similar toFigure 5 , shows a variant of the invention applied to a door with panic handle. - With reference to
Figure 1 , current motor-driven systems for automation of swinging leaves usually envisage: at least one swingingleaf 1, at least onearm actuator 2 equipped with afront attachment 3 fixed to the leaf to be opened/closed and with arear attachment 4 fixed to adoorpost 5 to which the leaf is hinged. - Usually, motor-driven swinging leaves are in any case provided with locks S that prevent opening of the leaf by non-authorized persons. Evidently, to be able to open the leaf in the case of failure of operation of the motor-driven opening mechanism, before acting on the releasing bolt and manually displacing the leaf it is necessary to open the lock S.
- The device forming the subject of the present invention, represented in
Figures 2 ,3 and 4 responds to the requirements referred to above and may be made of steel and/or metal alloys and/or plastic materials of adequate mechanical characteristics suitable for the use. - According to a peculiar characteristic of the invention, the device must be set between the
leaf 1 and thefront attachment 3 of the actuator 2 (seeFigure 4 ). - With reference to
Figures 5 and6 , the device comprises: - two elements having a length of approximately 50 cm, one of which is a
slide 6 designed to slide within the other element that functions asguide 7; - according to the invention, the
guide 7 is designed to be fixed to theleaf 1, and theslide 6 is designed to be constrained to thefront attachment 3 of theactuator 2; - a preferably wedge-shaped bolt 9 designed to slide within its
own casing 10 that is fixed with respect to theguide 7, the tip of which is designed to co-operate with a hole or slot appropriately provided in theslide 6 for blocking/releasing the latter with respect to theguide 7; - a
spring 11 designed to push the bolt 9 towards theslide 6; - an
internal manoeuvring rod 12 with end knob fixed to the bolt 9; and - an
external manoeuvring rod 13 with end knob fixed to the bolt 9 and passing through theleaf 1 by means of a hole appropriately made in the latter. - It should be noted that fixing of the
guide 7 to theleaf 1 can occur, for example, by means of screws passing in holes 8 appropriately provided in theguide 7 or by means of welding; the same may be said as regards the anchorage of theslide 6 to thefront end 3 of theactuator 2. - During the normal automatic operation of the door, the bolt 9 is inserted in a blocking position in the hole provided in the
slide 6, thanks to the thrust exerted by thespring 11. - In the example of embodiment illustrated, instead of a single hole in the
slide 6 for the end of the bolt 9, two slots or holes are provided, which are set on top of one another, are appropriately made one in theslide 6 and the other in the guide 7 (seeFigure 6 ), and are designed to receive the end of the bolt 9 that blocks them with respect to one another in such a way that they cannot slide with respect to one another. The result is that the device described mechanically constrains theleaf 1 of the door to thefront attachment 3 of theactuator 2, which may thus exert its action on the leaf itself. The tip of the bolt 9, opposing relative sliding between theslide 6 and theguide 7, is subject to a shear stress. - In the case illustrated, the tip of the bolt 9 is wedge-shaped, and consequently the holes or slots with which it co-operates have a section that is appropriately flared or V-shaped.
- According to the invention, in order to be able to move the leaf manually in a situation of emergency, for example in the case of failure or of absence of electrical supply, it is sufficient to pull (from inside) or push (from outside) the
corresponding manoeuvring rod spring 11. In this way, the bolt 9 will slide in itscasing 10, and its wedge-shaped tip will be disengaged from the two slots (Figure 6 ). - In said configuration, the
slide 6, which is fixed with respect to theactuator 2, is free to slide in theguide 7, which is instead fixed with respect to theleaf 1, consequently releasing theleaf 1 from theactuator 2, which cannot hinder the movement that the user impresses manually on the leaf itself. In practice, corresponding to the rotation of theleaf 1 is only a sliding of theslide 6 and not a shortening or lengthening of theactuator 2, which in this case turns about itsrear attachment 4 keeping its length unvaried (Figure 7 ). - Once the cause that has rendered the manoeuvre of release necessary has been solved, it is advantageously possible to constrain the
actuator 2 again to theleaf 1 by simply moving the leaf in the opposite direction. - According to the invention, in fact, as soon as the
leaf 1 is brought back into the original position, i.e., the one in which the manoeuvre of release has been made, the two slots or holes present on theslide 6 and on theguide 7 again set themselves on top of one another, and the tip of the bolt 9, pushed by thespring 11 and facilitated also by its wedge shape, automatically slides back into said holes, thus blocking theslide 6 again in theguide 7. At this point theactuator 2 can exert again its action on theleaf 1 impressing, in a known way, the movement upon the latter. - A variant of the invention envisages applying the releasing/blocking device described so far also to automated swinging doors equipped with panic handles.
- With said variant of the invention, the release device described so far makes it possible to use, as emergency exit, an automated swinging door (with opening towards the outside and without electrical lock) with the association of a normal panic handle.
- In this case, the panic handle is provided with an appropriate mechanism preferably of the lever type, designed to transmit the movement imposed by the user on the panic handle directly to the pin 9 described above, overcoming the force of the
spring 11 and bringing about immediate release of theslide 6 from itsguide 7 in such a way that the door can be opened without theactuator 2 opposing any resistance to said opening. - With reference to
Figure 8 , which shows a vertical section of the device with the variant referred to above, it should be noted that in this case, by pushing the panic handle 22 in the direction of the arrow, a purposely provided L-shapedlever 16 is operated, designed to displace backwards the pin 9 for releasing theslide 6 from therespective guide 7, in such a way that the door can be opened even if theactuator 2 is stationary. - In particular, the smaller side of the L-shaped
lever 16 is provided with an end slot A in such a way that the wedge-shaped bolt 9 is pulled by means of themanoeuvring rod 12, which in this variant is equipped with a throughpin 15 instead of with the knob already described. The throughpin 15 of the axial rod 24 is inserted in the slot A of the L-shapedlever 16, which turns about a purposely providedcorner pin 19 fixed to thecasing 10 of the pin 9 via asupport 14. - Along the
horizontal rod 26 of the panic handle 22 aring 18 is provided, which is preferably blocked by fiction in an appropriate position on therod 26 of the handle 22, by means of ascrew 21, which, by advancing through the threaded hole made in thering 18, grips the ring itself on the walls of therod 26, which as a result is in no way altered or mechanically weakened. - The
ring 18 is provided with abracket 27 equipped with an end pin 25, hinged to which is atelescopic rod 17 that is adjustable in length by means of blocking of a screw 28 screwed on the outer part of the rod itself. The other end of thetelescopic rod 17 is hinged, by means of apin 20, to the long end of the L-shapedlever 16, to which it transmits the movement imposed by the panic handle 22. Thetelescopic rod 17 is adjustable so as to adapt to the various dimensional situations that can arise according to the positioning of the actuator and the type of door and/or panic handle that is installed directly on theleaf 1 or with the interposition of adepth adapter 23 of a known type.
