Description

[0001] This invention relates to an operating system for a door or window.

[0002] In particular, the doors or windows according to the invention may comprise a fixed frame and a mobile frame with a side hung or tilt and turn opening.

[0003] Operating means comprise a plurality of movable rods positioned in the mobile frame in suitable housing channels and a plurality of bosses or pins fixed on the rods, in predetermined points of the fixed frame, configured to intercept contact elements associated with the fixed frame to determine the closed or open position of the door or window.

[0004] Control means makes it possible to operate the movement of the rods in such a way as to move the pins towards or away from the contact elements and determine a closed or open configuration of the mobile frame.

[0005] The control means may be in the form of a handle for a manual actuation or in the form of an electric actuator for an automatic actuation.

[0006] The handle may be associated or associable with the mobile frame in such a way that the user can control the closing or opening, of a side hung or tilt and turn type, of the mobile frame relative to the fixed frame by a relative rotation of it with respect to a pivot.

[0007] The electric actuator, usually associated with an upper crosspiece of the fixed frame, operates a movable kinematic unit which engages with a pin, associated with a respective rod, to control a sliding movement of the movable rods determining the closing or opening of the mobile frame relative to the fixed one.

[0008] The electric actuator is often required for controlling the opening of large tilt and turn doors and windows and, consequently, of considerable weight. In this situation, the electric actuator controls the movement of the movable rods to which is connected a system of articulated arms which allow the angled opening of the mobile frame to be controlled with respect to the fixed frame.

[0009] A correct tilt and turn opening, and consequent closing, depends on a correct relative movement of the entire kinematic mechanism which, in cascade, responds to the movement of the pin gripped by the movable kinematic unit driven by the electric actuator.

[0010] Consequently, when the door or window is closed, the various components of the kinematic mechanism, such as rods, pins, articulated arms, must be positioned in very precise relative positions, otherwise imprecise positions may determine a risk of incidental damage to the components due to an incorrect movement relative to the actuation of the electric actuator.

[0011] The imprecise positions are often determined following an operation of the operating system with the handle by the user, with the electric actuator switched off.

[0012] In fact, in doors and windows 1 with an electric actuator, the user can open the door or window manually to perform, for example, cleaning or maintenance operations.

[0013] For this reason, in the context in which there is both the automatic actuation for the tilt and turn opening and the manual actuation for opening and closing the door or window there is the need to preserve the correct movement of the kinematic mechanism actuated by the electric actuator for tilt and turn opening at the expense of manual opening.

[0014] The aim of the invention is to provide a system for operating a door or window which inhibits the tilt and turn opening if performed with a handle in order to preserve a correct opening and closing operation of the door or window by means of an electric actuator.

[0015] Said aim is fully achieved by a system for operating a door or window as described in independent claim 1.

[0016] Further features of the invention are described in the accompanying dependent claims.

[0017] The advantages of the invention are more apparent in the non-limiting description which follows of a non-exclusive embodiment of a system for operating a door or window as illustrated by way of example only and, therefore, without limiting the scope of the invention, in which: Figure 1 illustrates a door or window in which an operating system according to this invention is applied with some parts cut away to better illustrate others; Figure 2 illustrates a detail of the operating system with non-operating electric actuator and handle at 0°; Figure 3 illustrates a detail of the operating system with non-operating electric actuator and handle at 90°; Figure 4 illustrates a detail of the operating system with non-operating electric actuator and handle at 180°; - - Figure 5 illustrates a detail of the operating system of Figure 3 with some parts cut away to better illustrate others; Figure 6 illustrates a detail of the operating system in a first configuration corresponding to the door or window closed and electric actuator operational, automatic actuation; Figure 7 illustrates a detail of the operating system in a second configuration corresponding to the door or window open in a tilt and turn fashion and an electric actuator operational, automatic actuation; Figure 8 illustrates a detail of Figure 7 with some parts cut away to better illustrate others; Figures 9 and 10 illustrate the articulated arms in a closed / packed condition in the door or window closed or open in a side hung fashion and in an open / angled condition in the door or window open in tilt and turn fashion.

[0018] With reference to the accompanying drawings, and with particular reference to Figures 1, the operating device according to this invention, labelled 100 in its entirety, is applicable on doors and windows 1 having a fixed frame 2 and a mobile frame 3.

[0019] The door or window 1 passes from a closed configuration to an open configuration in relation to the relative position between the mobile frame 3 with respect to the fixed frame 2.

[0020] The open configuration of the door or window 1 comprises both a side hung opening and a tilt and turn opening.

[0021] The door or window 1 comprises operating means 7, positioned along its perimeter, for varying the relative position of the mobile frame 3 relative to the fixed frame 2 and moving the door or window 1 from the closed configuration to the open configuration, and vice versa, and in the open configuration for forming a side hung or tilt and turn opening.

[0022] The door or window 1 comprises means 4 for controlling the operating means 7 in the form of a handle 5 for a manual operation and an electric actuator 6 for an automatic operation.

[0023] The electric actuator 6 is provided with a relative protective casing 11.

[0024] According to this embodiment, the handle 5 can be associated with the mobile frame 3 in such a way that it can be inserted in and removed from a suitable seat when required.

[0025] However, is possible that the door or window 1 comprises a handle 5 stably coupled to the mobile frame 3 by suitable prior art fixing means.

[0026] The electric actuator 6 is fixed to a portion 2a of fixed frame 2 and is provided with movement means 8.

[0027] According to the embodiment illustrated, the electric actuator 6 is fixed along an upper crosspiece.

[0028] This does not exclude that the electric actuator 6 can be positioned in other parts of the fixed frame 2.

[0029] The movement means 8 comprises a plurality of interconnected, movable elements by translation along an advancement direction.

[0030] This direction is parallel to the longitudinal direction of extension of the portion 2a of frame 2.

[0031] The operating means 7, which vary the relative position of the mobile frame 3 relative to the fixed frame 2, comprise a plurality of rods 9 and pins 10 interconnected with each other.

[0032] With reference to the tilt and turn type opening, the operating means 7 comprise a plurality of arms 12 articulated to each other to pass from a packed / closed configuration to an angled / open configuration for forming the tilt and turn opening, as shown in Figures 9 and 10.

[0033] The articulated arms 12 have respective ends connected to the mobile frame 3 and to the fixed frame 2.

[0034] According to this embodiment, the electric actuator 6 actuates the operating means 7 for a tilt and turn opening of the door or window 1.

[0035] The operating system 100 according to this invention comprises the electric actuator 6 and the movement means 8 actuated by it.

[0036] The movement means 8 comprise a gripping element 8a is configured to grip one of the pins 10 of the operating means 7 in such a way as to push or pull it, in other words translating it in a direction or in the opposite direction, to obtain the opening or closing of the door or window 1.

[0037] The operating system 100 comprises a slide 101 movably connected to a bracket 102 supporting the slide 101 for translating along a direction D.

[0038] The bracket 102 is positioned close to the casing 11 for protecting the electric actuator 6.

[0039] The bracket 102 is connected to the fixed frame 2 of the door or window 1.

[0040] The bracket 102 and the casing 11 for protecting the electric actuator 6 are relatively fixed relative to the slide 101 and to the movement means 8.

[0041] Connecting means 106, 107 of the male / female type connect the slide 101 to the bracket 102.

[0042] The connecting means 106, 107 comprise one or more pins 106 for connecting the bracket 102 to the slide and one or more slots 107 made in the bracket 102 in each of which a respective pin 106 is inserted.

[0043] According to the embodiment illustrated, the coupling means 106, 107 comprise a pair of pins 106 and a pair of slots 107.

[0044] The slots 107 have a main longitudinal extension and their length defines the movement stroke of the slide 101 relative to the bracket 102.

[0045] The main longitudinal extension is intended to be parallel to the above-mentioned direction of translation.

[0046] The two ends of the slot 107, a first end 107a and a second end 107b, define the end of stroke positions of a respective pin 106.

[0047] Elastic means 103, in the form of a spring, are interposed between the slide 101 and the bracket 102 in a suitable seat 104.

[0048] The seat 104 has a first wall 104a and a second wall 104b for contact with the ends of the elastic means 103.

[0049] The first wall 104a is integral with the bracket 102 by means of the pin 106, the second wall 104b is integral with the slide 101.

[0050] The seat 104 has a main longitudinal extension and the first wall 104a and the second wall 104b are perpendicular relative to the longitudinal extension of the seat 104.

[0051] The main longitudinal extension is intended to be parallel to the above-mentioned direction of translation.

[0052] The seat 104 is configured to vary its longitudinal extension in relation to the relative position between the first wall 104a and the second wall 104b, that is, in relation to the relative position between the bracket 102 and the slide 101.

[0053] In particular, the extension of the seat 104 is variable between a minimum extension, wherein the elastic means 103 are in a compressed configuration, and a maximum extension, wherein the elastic means 103 are in an extended configuration.

[0054] The minimum extension of the seat 104 is reached in a position of maximum vicinity between the first wall 104a and the second wall 104b of the seat 104 corresponding to a position of the pin 106 in the first end 107a of the slot 107, see Figure 5.

[0055] The maximum extension of the seat 104 is reached in a position of maximum distance between the first wall 104a and the second wall 104b of the seat 104 corresponding to a position of the pin 106 in the second end 107b of the slot 107, see Figure 8.

[0056] The slide 101 has two ends, a free end 101a, and an end 101b positioned in contact with an element of the movement means 8.

[0057] When the window is in the closed position, at the non-operating position of the electric actuator 6, in the rest condition of the movement means 8, the slide 101 is positioned relative to the bracket 102 in such a way that the seat 104 of the elastic means 103 has a minimum extension and, consequently, the elastic means 103 are in compression, a condition reached in Figure 2.

[0058] In an operating condition of the electric actuator 6 for bringing the door or window from the closed position to the tilt and turn open position, by activating the gripping element 8a of the movement means 8for gripping one of the pins 10 of the operating means 7, the slide 101 is moved by being translated by the action of the elastic means 103, compensating for the gap between the element of the movement means 8 and the second end 101b of the slide 101, see Figure 6.

[0059] Once the pin 10 has been gripped, the gripping element 8a of the movement means 8 continues its translation to achieve the actuation of the operating means 7 and the articulated arms 12 for the tilt and turn opening (see Figure 7).

[0060] During this translation of the slide 101, the slot 107 translates relative to the pin 106 moving it towards the second end 107b of the slot 107 until it reaches the configuration of Figure 8.

[0061] At the second end 107b of the slot 107, the elastic means 103 cease their action since they are in the extended condition.

[0062] The elastic means 103 are moved in compression, following a translation in the opposite direction to that described, to pass from a tilt and turn open position to a closed position of the door or window 1.

[0063] The translation of the movement means 8 with the pin gripping occurs in the opposite direction relative to the previous one, the slot 107 translates relative to the pin 106 returning it towards the first end 107a at which the extension of the seat 106 is minimum, Figure 5.

[0064] According to the invention, the operating system 100 is configured to inhibit the tilt and turn opening of the door or window 1 if its opening is controlled by the handle 5.

[0065] This is possible as the slide 101 comprises retaining means 108 which can be engaged with the pin 10 to retain it in the tilt and turn opening position of the door or window 1 with the handle and in the non-operating condition of the electric actuator 6.

[0066] In this way, if the user associates the handle 5 to the mobile frame 3 and rotates the handle by 90° for the tilt and turn opening, the retaining means 108 do not allow the pin 10 to move for actuating the articulated arms 12, Figure 3.

[0067] The handle 5 can only be used for side hung opening, following a rotation through 180°, after which the pin 10 is disengaged from the retaining means 108, Figure 4.

[0068] It should be noted that the manual operation with the handle 5 moves the operating means 7 relative to the slide 101, which moves the retaining means 108, which maintains its position since the electric actuator 6 is not operational, as shown in Figures 2 to 4.

[0069] It should be noted that, upon the actuation of the electric actuator 6, the retaining means 108 translate with the slide 101 leaving the pin 10 disengaged to allow the tilt and turn opening of the door or window 1, as in Figure 7.

[0070] The retaining means 108 are in the form of side panels, facing each other. When the door or window 1 is closed, whether the actuation is with the handle 5 or automatically with an electric actuator 6, the control pin 10 of the articulated arms 12 is disengaged from the retaining means, see Figure 2.

[0071] According to this invention, the retaining means 108 can be engaged with a pin 10 for controlling the opening and closing of the articulated arms 12 for keeping it in a non-operating condition of the electric actuator 6 and in a position of the handle 5, preferably by 90°, corresponding to a tilt and turn opening configuration of the door or window 1 and for disengaging it in an operating condition of the electric actuator 6 for forming a tilt and turn opening of the door or window 1.

[0072] This allows the kinematic mechanisms designed for the tilt and turn opening of the door or window 1 to be preserved if the door or window is opened manually, preventing the user from opening it in a tilt and turn fashion.

[0073] The tilt and turn opening are only allowed by an electric actuator 6 and, therefore, if it is operational the pin 10 for controlling the opening of the articulated arms 12 is free to move.
